Description

Technical Field

[0001] The invention relates to the technical field of life jackets, in particular to a quick-wearing multifunctional life jacket. Background Art

[0002] Life jackets are required in maritime operations, water sports, and emergency rescue. Life jackets can protect the wearer and extend the time for subsequent rescue work. The life jackets currently on the market have a variety of functional designs, which enable them to protect the wearer to the greatest extent. For example, the patent disclosed in the prior art with the publication number "CN115520354A" is named "A multifunctional rapids life jacket that is easy to wear", which discloses a fixing ring, a locking rope, a shoulder guard and a connecting belt structure, so that the life jacket can be quickly put on. When putting on the life jacket body, first pass both arms through the locking rope at the bottom end of the fixing ring, and then drape the shoulder guard fixedly connected by the connecting belt around the shoulders of the person to prevent the shoulders of the person from being injured under water. By pulling the locking belt, the life jacket body is prevented from floating upward when the person enters the water, thereby avoiding the need for the person to bend over and use the crotch rope to fix the life jacket, making it more convenient and quick for the person to put on the life jacket body, thereby improving the wearing effect of the life jacket body. For example, the patent disclosed in the prior art with the publication number "CN210681097U" The patent is titled "A Quick-Don and Buckle Life Jacket", which discloses that when in use, the life jacket consists of a front half and a back half. The user puts it on from the top of the head through the perforation, and then aligns the two sides of the armpits. It is first fixed by binding the fixing straps on the insertion layer, and then pulls the zippers on both sides from the bottom up to the end of the zipper, and finally fastens the fixing buckles on the inflatable layer to complete the entire quick-donning process. The structure is simple and easy to use. The perforations are wrapped with elastic bands to solve the problem of looseness around the user's neck. The surface layer of the life jacket is an inflatable layer, which can be inflated through the inflation holes below. The inflatable layer will not expand under the action of the fixed line. At the same time, the back layer of the life jacket is an insertion layer. The user can fill the insertion layer or replace the floating sponge structure through the filling port below, which is faster to use.

[0003] When donning the life jacket in the prior art, although the life jacket is first fixed by tying the fixing straps on the inserting layer and then pulling the zippers on both sides upwards from the bottom, this operation can achieve a quick-donning effect to a certain extent, but the process of tying the fixing straps and pulling the zippers takes a long time, and thus the quick-donning effect cannot be further achieved. Therefore, we propose a quick-donning multifunctional life jacket to solve the above problems. Summary of the Invention

Subsequently, the protective plate and the extension plates are used in conjunction with each other to increase the usable area of the protective plate, making it easier for the user's hands and front half of the body to lie on the protective plate, further improving the supporting force. At the same time, the user blows air into the air tube continuously, so that the user can inhale and exhale continuously. This operation is repeated, which not only makes it easier to blow air into the air tube, but also makes it easier for the user to take a deep breath, thereby reducing the user's tension.

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figures 1-8 , the present invention provides the following technical solutions: Embodiment 1: The quick-wear multifunctional life jacket in this embodiment can further facilitate the quick-wear operation and reduce the time spent on wearing, so it is easy to wear the life jacket. At the same time, the life jacket has diverse functions and can meet different usage needs. For specific structure, please refer to the attached Figure 1-Figure 5As shown, it includes a shoulder protection cloth assembly 1 with a sleeve hole 2 in the middle, the rear side of the shoulder protection cloth assembly 1 is connected to the rear protection cloth assembly 4, and the front side of the shoulder protection cloth assembly 1 is connected to the front protection cloth assembly 3, and rubber rods 15 are installed in the shoulder protection cloth assembly 1 on the left and right sides of the sleeve hole 2, the left and right sides of the front protection cloth assembly 3 and the rear protection cloth assembly 4 are connected by a quick-connect assembly, the front side of the front protection cloth assembly 3 is connected to the protective plate 9 through the installation rope 10, the rear end of the rubber rod 15 is inserted into the upper interior of the rear protection cloth assembly 4, and the front end of the rubber rod 15 is inserted into the upper interior of the front protection cloth assembly 3, and the length of the rubber rod 15 inside the front protection cloth assembly 3 and the rear protection cloth assembly 4 is equal to that of the front protection cloth assembly The quick-connect assembly is one-quarter of the length of the component 3. The quick-connect assembly includes a first Velcro 5 installed on the left and right sides of the rear protective cloth assembly 4, and a connecting rope 7 is installed on one side of the first Velcro 5. A fixing ring 71 is installed on the end of the connecting rope 7 away from the first Velcro 5. The connecting rope 7, the fixing ring 71 and the installation rope 10 are made of rubber band material. The left and right sides of the front protective cloth assembly 3 are fixed with a second Velcro 6, and the second Velcro 6 is bonded to the first Velcro 5. The front side of the front protective cloth assembly 3 is symmetrically installed with a fixing buckle 8, which is sleeved with the fixing ring 71. The front protective cloth assembly 3 and the rear protective cloth assembly 4 are arranged in an inclined shape, and the shoulder protective cloth assembly 1, the front protective cloth assembly 3 and the rear protective cloth assembly 4 form an inverted "V" shape.

[0020] First, put the whole life jacket as shown in the Figure 1-Figure 3 As shown in the figure, at this time, since a row of rubber rods 15 are installed in the shoulder protection cloth assembly 1, the front protection cloth assembly 3 and the rear protection cloth assembly 4 are well stretched outward by the row of rubber rods 15, so that the distance between the front protection cloth assembly 3 and the rear protection cloth assembly 4 is larger. This arrangement makes it unnecessary to manually stretch the front protection cloth assembly 3 and the rear protection cloth assembly 4 outward when wearing, so the operation is convenient, time-saving and labor-saving. At this time, you can manually take out the front protection cloth assembly 3 and the rear protection cloth assembly 4, pass the head through the head hole 2, and then make the shoulder protection cloth assembly 1 Contact with the shoulder part, then manually pull the connecting rope 7 and the fixing ring 71 of the rubber band material with a certain elasticity on the left and right sides of the rear protective cloth assembly 4, so that the rear protective cloth assembly 4 fits the back position of the human body, and manually press the front protective cloth assembly 3 to make the front protective cloth assembly 3 fit the chest position of the human body, put the fixing ring 71 on the outside of the fixing buckle 8, and at the same time stick the first Velcro 5 and the second Velcro 6 to fix them. At this time, the rubber rod 15 is bent, and then the entire life jacket can be put on. The operation is convenient and the life jacket can be put on quickly.

[0021] When the life jacket needs to be taken off later, the fixing ring 71 is separated from the fixing buckle 8 as shown above, and the first Velcro 5 is separated from the second Velcro 6. At this time, the bent rubber rod 15 slowly recovers its deformation, so that the rubber rod 15 can drive the front protective cloth assembly 3 and the rear protective cloth assembly 4 to expand outwards, as shown in the attached figure. Figure 1-Figure 2 As shown, at this time, the life jacket can be quickly taken off by moving the head downward from the head hole 2. During the taking-off process, there is no need to manually stretch the front protective cloth assembly 3 and the rear protective cloth assembly 4 outward, and the operation is convenient.

[0022] When a user falls into the water while wearing a life jacket, the life jacket composed of the shoulder protection cloth assembly 1, the front protection cloth assembly 3 and the rear protection cloth assembly 4 will protect the user's body, allowing the user's body to float on the water. The materials of the shoulder protection cloth assembly 1, the front protection cloth assembly 3 and the rear protection cloth assembly 4 are the same as those of existing life jackets on the market, so they are not introduced in detail here. At this time, the user can manually pick up the protective plate 9 so that the protective plate 9 is placed in a horizontal state. At this time, the protective plate 9 floats on the water, and then the user's hands and front half of the body can lie on the protective plate 9, so that the protective plate 9 can be used as a float on the market to provide a certain floating support force for the user who falls into the water, thereby making the life jacket functionally diverse and meeting different usage needs.

[0023] Embodiment 2: The quick-wear multifunctional life jacket in this embodiment can further increase the area of the protective plate 9 on the basis of embodiment 1, thereby further improving the supporting force of the protective plate 9. For the specific structure, refer to the attached Figure 5-Figure 8 As shown, the left and right sides of the protective plate 9 are grooved and slidably connected with the extension plate 12, and the left and right sides of the protective plate 9 are provided with slide grooves 91, and sliders 121 are installed inside the front and rear sides of the extension plate 12, and the sliders 121 are engaged and slidably connected with the slide grooves 91. The length of the slide grooves 91 is less than half the length of the protective plate 9. Staggered air storage pipes 13 are installed in the upper and lower interiors of the protective plate 9, and the interior of the air storage pipes 13 is fitted with a piston assembly 131 for sliding connection. One end of the piston assembly 131 is connected to the extension plate 12 at the corresponding position, and an air blowing pipe 11 is installed in the middle of the air storage pipe 13. The air blowing pipe 11 is connected to the rear side of the protective plate 9, and a valve is installed inside the outer end of the air blowing pipe 11. The rear side of the protective plate 9 is provided with an inclined "U"-shaped air supply pipe 14, and both ends of the air supply pipe 14 pass through the rear side of the protective plate 9 and are respectively inserted into one end of the two air storage pipes 13.

[0024] When the protective plate 9 is placed in a horizontal state, the user can take a deep breath first, and then blow air into the air blowing pipe 11, and then control the valve in the port of the air blowing pipe 11 to block the port of the air blowing pipe 11 to prevent air leakage, and then take a deep breath again, and then open the valve to blow air into the air blowing pipe 11, and repeat this process several times, so that the gas in the air blowing pipe 11 enters the air delivery pipe 14, and then the gas is simultaneously delivered to the two air storage pipes 13 through the "U"-shaped air delivery pipe 14. When the gas in the air storage pipe 13 increases, the piston assembly 131 is pushed outward, and then the piston assembly 131 is pushed outward. Component 131 drives the extension plate 12 at the corresponding position to move outward. At this time, the sliders 121 on the front and rear sides of the extension plate 12 slide stably in the slide groove 91 in the protective plate 9. When the extension plate 12 slides to a certain position, the blowing into the air pipe 11 is stopped and the valve is closed. This allows the extension plates 12 on the left and right sides of the protective plate 9 to move outward and expand well. Subsequently, through the coordinated use of the protective plate 9 and the extension plate 12, the usable area of the protective plate 9 can be increased, which makes it easier for the user's hands and front half of the body to lie on the protective plate 9, further improving the supporting force.

[0025] At the same time, the user blows air into the air blowing tube 11 continuously, so that the user can inhale and exhale continuously. This operation is repeated, which not only makes it easier to blow air into the air blowing tube 11, but also makes it easier for the user to take a deep breath, which can reduce the user's tension and thus complete a series of tasks.

[0026] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
