Inflatable life jackets are made by forcefully pulling the pull rope on the inflation device, causing the pull rod to rotate at least 90 degrees. The needle pierces the diaphragm in the high-pressure gas storage cylinder (disposable, replaceable), and high-pressure carbon dioxide gas rushes into the airbag. The gas expands to generate buoyancy, thus achieving the purpose of life saving. Inflatable life jackets mainly consist of sealed inflatable vest airbags, miniature high-pressure gas cylinders, and quick inflation valves, and are often used in work with the possibility of falling into the water. Under normal circumstances (not inflated), the entire inflatable life jacket is worn as a belt and draped over a person's shoulder. Due to its compact size, it does not hinder people's freedom of operation; Once falling into the water and encountering a danger that requires buoyancy in an emergency, it can automatically expand and inflate according to the action of the water (fully automatic inflatable lifejacket), or manually pull the cable on the inflation valve (manual inflatable lifejacket), which will complete inflation within 5 seconds to generate 8-15 kilograms of buoyancy, lift the human body upwards, and expose the head and shoulders of the person who accidentally fell into the water to obtain safety protection in a timely manner.

Firstly, before use, it is necessary to carefully check to ensure that the lap is intact and undamaged; After confirming that there is no damage to the baby's swimming lap, inflate it; Attention: The baby swimming circle has five inflation ports, which should be inflated in the correct order; The inflation sequence is: first inflate the abdominal airbag, then inflate the back strap, then the protective airbags on both sides, and finally inflate the main airbag; After inflation, cover the air nozzle well and do not inflate too much, reaching 80% is sufficient to avoid affecting comfort; Press the air nozzle into the swimming circle, ensure that the surface of the lap is flat, and place it in water for about 20 minutes to check again for air leakage; When confirming that there is no air leakage, moisten the baby's skin, place the baby in the lap and fasten the straps;

Single day hiking without camping itinerary - Outdoor backpacks within 30L are usually sufficient for single day hiking. If you are hiking lightly on weekends, then your outdoor backpack only needs to carry the basic equipment commonly used throughout the year. For example, raincoats, insulated cups, daily food and water, life blankets, headlights, and warm clothing; When choosing a backpack, there is also a need for a hanging point to hang or fix inconvenient hiking sticks and tripods. A suitable day backpack can achieve twice the result with half the effort in various hiking activities. 2-3 day hiking or camping - When hiking or camping for 2-3 days, mountain enthusiasts should choose a backpack with a capacity of 30L-50L, which is just right. A backpack larger than 40L is large enough if filled. If lightweight and in place, only 40L can fully accommodate all materials for 2-3 days, such as tents, sleeping bags, moisture-proof mats, food, water, cooking utensils, down jackets, and submachine jackets. If you carry around 40 pounds for heavy hiking, 60L is enough for most activities. (Over 5 days) Multi day Hiking - Undoubtedly, a large outdoor backpack with a capacity between 60L and 85L is an essential equipment for long-distance hiking. The well-known Wolf Tower, Xiate, and Aotai Crossing in China are all very suitable. If you are interested, please visit https://www.dydoing.com.

Compared to ordinary outdoor activities, hiking is an outdoor activity carried out for the purpose of physical and mental pleasure or health, accompanied by a certain amount of weight. If we only carry ordinary daily backpacks, it often brings us many problems. Compared to professional outdoor backpacks, ordinary daily backpacks do not have a backpack and cannot provide us with support during long and long-distance treks. The fabric of ordinary daily backpacks is generally made of canvas, leather, or other synthetic materials. Professional outdoor backpacks usually need to be adjusted according to the climate and outdoor environment, providing waterproof, durable and other functions to meet the needs of mountain enthusiasts camping or hiking. Ordinary daily backpacks do not have padded shoulder straps, while professional outdoor backpacks have shoulder straps and belts that can wrap around our bodies more comprehensively, ensuring that they do not shake during hiking. Secondly, the comfort of outdoor backpacks is incomparable to ordinary daily backpacks. When walking outdoors, you need a professional outdoor bag to enjoy walking in the mountains.

A waterproof backpack has a unique process from design to formation and cannot be arbitrarily modified, and every process in the production process will affect the quality of the backpack. Generally speaking, the production process of backpacks includes various processes such as material selection, sampling, sample setting, material preparation, cutting, sheet printing, sewing, packaging, etc. A backpack is usually assembled by splicing dozens or even hundreds of components, and the complexity of its production is self-evident. Sewing is the most important process in the production of backpacks, which directly affects the quality of the entire backpack's workmanship. Sewing can be divided into front seam, seam surround, seam lining, filler seam, seam side pocket, seam accessories, assembly accessories, installation pull head, seam back seam, high seam integration package, etc. Each process is very important. Designing a special backpack even requires the use of some special techniques, such as skinning, laminating, oiling, gluing, riveting, drawing, spraying, etc. In order to make a high-quality backpack, every process must be strictly controlled.

Target muscle groups: latissimus dorsi, trapezius, rhomboid, core Just like the practice methods of barbells and dumbbells, you can also use sandbags to strengthen your back muscles. Grasp the sandbag with both hands, bend your knees slightly, align your neck, back, and buttocks, and keep your weight back with your buttocks. After fixing the posture, place your consciousness on your back, feel the compression of your back muscles, pull the sandbag from the floor to your chest, and repeat the movements back and forth. Basically, the weight of the sandbag comes from the filling material inside the sandbag (usually filled with bags of soft sand). The advantage of this is that you can adjust the weight according to your personal abilities; It is relatively safer to throw, throw, hit, and kick heavily.

Target muscle groups: legs, buttocks, shoulders From holding a barbell, bending the knee to receiving the bar, the power clean movement can be said to be quite complex. Practicing with barbells not only requires a lot of explosive power, excellent softness, and stability, but most people do not recommend practicing on their own without the assistance of professionals. In contrast, sandbags have a large volume and a soft surface, especially when connected to sandbags, their risk is relatively low. Whether you use a barbell or a sandbag, the high somersault movement still needs to be practiced to improve athletic performance. 1. With feet shoulder width apart, straighten your back, crouch back, and grab the sandbag. 2. Using the force of standing straight on your buttocks and legs, pull the sandbag up to the chest position, and prepare to reach out your forearm to catch the sandbag. 3. When catching the sandbag, the upper arm will be parallel to the ground, and the knee can be slightly bent to facilitate you to catch the sandbag. At this time, the wrist will also be folded upwards. 4. Finally, straighten your arms and squat your body back to the starting position. The sandbag will follow the trajectory and roll back to its starting position. If you are interested, please visit https://www.

Target muscle groups: legs, buttocks, shoulders, hands Place the sandbag in front of your toes, with the grip facing up. Feet shoulder width (or slightly wider than shoulder width). 1. Squat back straight, buttocks back, and grasp the sandbag. 2. Using the force of standing straight on your buttocks and legs, pull the sandbag up to the height of your chin, and your elbows will extend outward. 3. Finally, let gravity take you back to the preparatory action, but due to the fast speed of the action, there may be a lack of reaction and the phenomenon of "rounded back". Remember to keep your head, back, and waist straight as much as possible during the movement. If you are interested, please visit https://www.dydoing.com.

This type of fitness aqua bag, due to the inertia of its fluid at the beginning and end of the movement, allows the human body to mobilize more muscles to control, which can effectively train the body's ability to accelerate, brake, and change gears during movement. Due to the fluidity, instability, and inertia of the contents of this training water bag, it can cause unstable interference in various directions for the human body during movement, forcing the activation of deep stabilizing muscles and shallow large muscle groups in various parts of the body to complete stable movements. This allows ordinary training movements to reach muscle groups that cannot be fully practiced in daily life, greatly improving the efficiency of training. This water bag has an automatic exhaust valve, which can be filled with water, inflated, and folded. The weight of the water bag can be controlled by the amount of water injected, thereby meeting the requirements of strength training. The functional safety and material safety factor of this water bag are extremely high. The new PVC material will not cause harm to humans, effectively avoiding sports injuries, and ensuring safe and efficient sports training and rehabilitation treatment. This water bag is made of imported materials and bonded with imported glue, with high strength, compression resistance, tear resistance, resistance to scorching sun exposure, corrosion resistance, wear resistance, high temperature resistance, hydrolysis resistance, and UV resistance.

Fitness Aqua Bag Moving Scissor Squat The movement requirements are no different from those of barehanded squatting. During the movement, the body must strive to maintain balance by controlling the center of gravity of the water bag, greatly increasing the difficulty of the movement. Fitness Aqua Bag Over Top Squat There are many benefits to deep squatting, with water bags over the top. Deep squatting requires a certain level of shoulder blade flexibility, which is difficult for those with poor shoulder blade flexibility to complete. Note that during the squat, the core is stable, the arms are straightened, and the center of gravity is maintained, which will recruit and utilize more of our small muscle groups. Fitness Aqua Bag flipping high The water bag flip is usually initiated in a hanging flip form, rarely starting from the ground. The technical points are the same as flipping, lifting the water bag to shrug, stretching the hips and legs, actively extending the elbows, and bending the knees to give way to the water bag. Fitness Aqua Bag thrown at each other (requires cooperation from two people) This action is a great exercise for core stability, requiring the core to tighten throughout the entire process

Compared to instruments such as barbells, the highly imbalanced and unstable weight-bearing water bag training has long been popular in Europe and America. The main reason is that when the water volume is one-third to half of the volume of the water bag, it provides a space for the water flow to collide, causing the water to constantly shake in the bag. At this time, the water bag is in an extremely unbalanced and unstable state. The difficulty will increase exponentially because the center of gravity is constantly moving, requiring higher control over the core muscle group, and the body must constantly adjust to maintain balance and maintain a good posture. The recommended water content for a sleeping bag is one-third to one-half of the volume of the water bag. Provide a space for water flow to collide and better utilize the characteristics of water bags. In order to strive to maintain the stability of the center of gravity of the water bag, our body must also constantly adjust to maintain balance and maintain a good posture, so that our body is always in a tense state. Enhance the stability of the core and strengthen the balance attribute. This helps trainees to independently maintain and control body stability, maintain balance, and improve exercise performance under various sports situations. Many barbells can play and do the same movements as our water bags. The difficulty of water bags will increase exponentially, as the center of gravity is constantly moving, requiring higher core control. Training actions: Water bag cutting squat, water bag over top deep squat, water bag flipping,

The basic production process of a set of couches can be divided into: the production of sofa frames, frame bottoming, sofa fillers, jacket cutting and sewing, and a set of sofa jackets. Production of sofa frame Before starting the production of sofas, experienced masters will draw a good sofa board, and without a good sample, it is impossible to make a good set of sofas. After the board is ready, the frame of the sofa can be officially made. At present, sofa frames are mainly divided into solid wood and composite boards. The frame of a sofa is similar to a human skeleton, supporting the entire sofa. The firmness of the sofa frame structure and the rationality of the design angle will affect the quality and functionality of the sofa. Underlay The foundation mainly involves adding springs and bandages to the sofa. 1. Rubbing: Tie rubber bands on the back of the sofa! Because the load-bearing capacity of the back frame is not as large as that of the seat frame, rubber bands can be used. Some people also use so-called black belts, which are made from discarded tires. 2. Safety spring: Springs generally use serpentine s

(1) The front and back sides of the air cushion bed are mistaken The reason for the mistake between the front and back sides is that some people are not familiar with the laying method of air cushion beds, and neglect the difference between the front and back sides when laying. Instead, the side that should have been laid on the bottom is laid on top, and the side that should have been laid on the top is laid on the bottom. (2) Using a disposable single bed on or under an air cushion bed In order to prevent air cushion beds from being contaminated, some air cushion bed users place disposable sheets (plastic or rubber products) above or below the sheets, which can easily lead to pressure ulcers in the elderly. Plastic or rubber products have strong waterproof properties and can effectively protect the air cushion bed from contamination by secretions or excreta. However, their poor breathability can affect the airflow after use, greatly reducing the function of the air cushion bed to keep the skin dry.

Step 1: Preparation Before deflating, we need to do some preparatory work. Firstly, close all valves on the air cushion bed. Secondly, prepare an electric or manual inflation pump. If you are using an electric inflation pump, you need to ensure that the power supply of the inflation pump is sufficient. Finally, locate the air outlet on the air cushion bed, usually located next to the mattress or on the bedstead. Step 2: Bleed Next, we can start deflating. Firstly, open the air vent on the air cushion bed. If you are using a manual inflation pump, you can connect the bell mouth of the inflation pump to the air outlet, and then press the handle of the inflation pump to allow air to flow out of the air cushion bed. If you are using an electric inflation pump, you can connect the hose of the inflation pump to the air release port, and then adjust the inflation pump to the air release mode to allow air to flow out of the air cushion bed. Step 3: Roll up the air cushion bed After the air cushion bed is deflated, we can start rolling it up. Firstly, remove all the sheets, blankets, and other items from the air cushion bed. Then, starting from one side of the mattress, gradually roll up the air cushion bed. During the rolling process, it is necessary to gradually press out the air in order to make the air cushion bed more compact. Step 4: Store the air cushion bed Aft

1. After the gas bed is purchased, it can be inflated immediately, but it can only be used after 8 hours (preferably 12 hours) of initial inflation. The tension straps and seams inside the gas bed require a buffering process; 2. Within 24 hours after the first inflation, the air bed will become slightly loose, which is a normal phenomenon. The material of the air bed is a bit elastic, and after inflation, the bed will become slightly swollen and soft, feeling relaxed. As long as the inflation reaches the desired effect, it is enough, but it cannot be inflated too much; 3. One person can use it to replenish some qi, while two people need to release some qi when using it; 4. During seasonal changes, the temperature rises and the gas inside the bed expands. Pay attention to deflation; On the contrary, when the temperature drops, the bed will become soft, so pay attention to supplementing air appropriately; 5. Any inflatable product (including tires) will naturally leak air, which is a normal phenomenon. Pay attention to regularly replenishing air; 6. Ensure that the floor or bed frame on which the bed is made is free from sharp objects such as nails or thorns; 7. If used in water, ensure that the suede surface is facing upwards and children should use it under adult supervision.

Compared to common beds, water beds are more in line with the curves of the human body, reducing stress on the body, and improving comfort. The pressure on the water surface is lower, and the treatment effect is better. Later, after continuous improvement, it was improved to have the current water bed. In fact, the water in the water bed is all specially treated water. To ensure that the water inside does not become odorous over time, some preservatives will be added. So what if the water wound ruptures? People also consider the possibility of a water bed breaking, but it is rare because during production, special substances are added to ensure that the water bed can withstand the weight of four or five people, even if it breaks, without causing significant harm. In addition, the material of the water bed is a substance that does not absorb dust, which is a blessing for those who are very sensitive to dust and asthma patients. Although water beds are not yet common in our daily lives, they are already used by many people in some European and American countries. Water beds are also a very healthy way of life because water can adjust the body temperature and regulate the body's temperature. Moreover, using water beds is very comfortable and can improve the quality of sleep. If you are interested, please visit https://www.dydoing.com.

The production process of backpacks for different purposes is similar, but it is basically inseparable from the word "sewing". As for the quality of the finished product, it largely depends on the fabric and the skill of the sewing technician. Here, you know what details determine success or failure. Firstly, it is the collection of fabrics. It is understood that the commonly used fabrics and fabrics in backpacks include: DuPont nylon fabric, Oxford nylon fabric, high-density nylon fabric, adhesive nylon fabric, etc. (For information on the uses of various fabrics and fabrics, please go to the end of the article). Only a few commonly used fabrics are introduced here, and each manufacturer may also have their own secret recipe in the actual production process. This category involving trade secrets will not be discussed. The next task is to turn the backpack on the blueprint into a physical object. Cutting is an indispensable process. The entire piece of cloth is cut into small pieces according to the specifications as needed, which correspond to various parts of the backpack, such as the mesh pocket, rain cover, helmet cover... Of course, when cutting, enough space must also be reserved for easy sewing. Furthermore, it involves stitching each part one by one. In the workshop, every part of the backpack is sewn by fixed tailors, most of whom are women. Some of them have been engaged in this industry for more than ten years and are already skilled. They are agile and their stitching is clean and smooth, without any procrastination. Usually, several tailors work together to form a production line, which is manually sewn using a sewing machine. After several steps, the prototype

Student and office workers: neck protection is crucial Teenagers are in the stage of physical development, and their bodies have great plasticity. Especially during this period, attention should be paid to protecting the cervical spine. Most parents choose soft mattresses to provide comfort to their children with heavy academic workload, which can help them sleep comfortably and with peace of mind. Little did they know that a soft mattress may not be beneficial for a child's body. As for office workers, they spend most of their time working and resting on their computers and phones, and neck soreness is a common problem for almost everyone. In addition to changing the habit of bowing your head for a long time, strengthening shoulder and neck movements can alleviate discomfort. In addition, when sleeping at night, choosing a comfortable mattress is particularly crucial for relaxing and restoring the neck and shoulders during sleep. The elderly: neither too soft nor too hard Short sleep time and low quality are the confusion of many elderly people. In addition, elderly people are prone to problems such as osteoporosis, lumbar muscle strain, and lower back and leg pain, so they are not suitable for sleeping on soft beds. A suitable mattress for the elderly should maintain normal physiological lordosis of the lumbar spine when the body is in a supine position, without lateral curvature of the lumbar spine. Th

1. Is it comfortable to touch the mattress Touching a mattress is not about touching a girl. When touching it, pay attention to the following points: The threads on the fabric should be uniformly elastic and tight, without wrinkles, jumpers, etc The edges of the mattress are evenly curved and there are no exposed edges Heavy pressure mattress, no friction sound inside, very comfortable to touch 2. Smell if there is any pungent odor in the inner bladder Open the zipper to check the inner lining of the mattress and smell if the smell of the lining is pungent. 3. Lie down and feel if it fits your body well Nowadays, many businesses highly recommend experiencing a mattress in person, so lie down and sleep for ten minutes. If this mattress has good elasticity and is enough to fit the body curve, then there is nothing wrong. If a double mattress, it would be even better if one person did not feel the shaking of the mattress while rolling over.

Stacking two sleeping pads is not a difficult method to think of, as it was first seen being used during camping in Houhe in the winter of 2016. Now this method is more popular. On the one hand, it is estimated that the air cushion and foam cushion equipment have made some progress in lightweight, especially the foam cushion. The minimum value of 1.4R foam cushion is only 99 grams, and there are many styles of inflatable cushion below 300 grams. Superimposed use does not add too much weight, but it can bring additional benefits. Taken together, the value of double sleeping pads is higher. The advantage of stacking - using two sleeping pads on top of each other not only makes them warmer and more reliable, but also has many additional benefits. 1. It is warmer. The foam pad under the air cushion can enhance the warmth retention (the R value after superposition should be less than the R value of the two), which can expand the original three season sleeping pad to four season sleeping pad. Not only can it save money, but it can also be more silent, because: the sleeping pad with a high R value (about 5 or more), or it is noisy (multiple compartments are used inside, and the materials for turning over will sound, such as the NeoAir of ThermoARest, which will be loud when turning over), or it is heavier (more thermal insulation materials are filled inside). If you can use a lower R value sleeping pad with a foam pad, the weight may not be heavier, but it may also be more silent. 2. More reliable. The superposition of the two brings more reliability than the previous one. Because the air cushion can't be used once it is punctured, the foam cushion is not preferred in many o

It's really difficult to rest on a business trip, travel, and tiring journey. A regular U-shaped pillow is as big as that, and whoever takes care of it will be in trouble. Even if it is reluctantly stuffed into the bag, it is too soft and unsupported, and too hard for the neck, it is a waste of space in vain. This inflatable pillow that can be massaged is super portable. While perfectly fitting and supporting your head, neck, and shoulders, it can also simulate a real person massage to relax the stiff and sore neck. It is definitely a must-have for business trips and office rest! I'm most afraid of having too much luggage when I go out, which is heavy and troublesome. This massage neck pillow looks no different from a regular neck pillow, but it is inflatable and does not have heavy padding. After releasing the air, it becomes the size of a scarf and can be easily stuffed into a suitcase or bag. It can be carried wirelessly and has an ultra long range, and can be used anywhere. The hump of the back neck is raised and filled with high-density memory cotton. The cheeks are slightly higher on both sides and lower on the other parts, perfectly fitting the ergonomic curve, providing soft and powerful support for your head, neck, and cheeks. Wearing it around the neck, the buckle design can adjust the neck circumference, and the air valve can adjust elasticity. No matter how long or thin your neck is, front, back, left, or right, it will follow you, providing good support without any pressure. So whether you sleep on
