TECHNICAL FIELD

[0001] The present application relates to the technical field of lifesaving equipment, in particular to a folding inflatable life jacket. BACKGROUND

[0002] Common life jackets are mostly a kind of life-saving clothes designed like a vest, which have important applications in many fields such as water sports, water operations, water entertainment, emergency rescue, etc. However, the existing life jackets are generally inflatable, which occupy a large volume and are inconvenient for users to carry, and need to be worn on the body or held in hand at all times, which limits the other actions of the users, and thus needs to be improved. CONTENT OF THE UTILITY MODEL

[0003] In order to improve the portability and applicability of the life jacket, the present application provides a folding inflatable life jacket.

[0004] The folding inflatable life jacket provided by the present application adopts the following technical scheme:

[0005] The folding inflatable life jacket comprises a folding air bag, a wearing gap for the head of a user is formed on the folding air bag, two buoyancy air bags are arranged on the bottom wall of the folding air bag, the folding air bag and the buoyancy air bags are in communication with each other, a valve seat is arranged on one of the buoyancy air bags, and an inflation assembly for inflating the folding air bag is mounted on the valve seat.

[0006] By adopting the above technical scheme, when the life jacket is not needed, no gas exists in the folding air bag and the buoyancy air bags, and thus the folding air bag and the buoyancy air bags occupy a small volume and can be folded and stored in a waist bag, so as to facilitate the user to carry it on the body. When the life jacket is needed, the air bag can be quickly inflated only by the inflation assembly, so as to improve the convenience and applicability of the life jacket.

[0007] Optionally, the inflation assembly comprises an inflation valve and a gas storage tank, the inflation valve is in communication with the valve seat, a connecting pipe for mounting the gas storage tank is arranged on the inflation valve, the open end of the gas storage tank is inserted into the connecting pipe, a diaphragm is arranged on the inner wall of the open end of the gas storage tank, a thimble is arranged in the connecting pipe, a driving pipe is arranged on the surface of the inflation valve, a pressing column is slidably connected in the driving pipe, one end of the pressing column is inserted into the inflation valve, a flap is arranged in the inflation valve, the flap is rotatably connected with the bottom wall of the inflation valve, one end of the flap is connected with the pressing column, and the other end of the flap is connected with the bottom wall of the thimble, an elastic member is arranged in the driving pipe, and the elastic member makes the pressing column tend to extend out of the driving pipe.

[0008] By adopting the above technical scheme, when the user needs to inflate the buoyancy air bag and the folding air bag, the user needs to press the pressing column, the pressing column drives the rocker plate to rotate, one end of the rocker plate connected with the pressing column is pressed down, on the contrary, one end of the rocker plate with the thimble moves towards the direction of the gas storage tank, so that the thimble pierces the diaphragm, and then inflation is realized, which is high in convenience.

[0009] Optionally, the inflation assembly further comprises a drive wrench, the drive wrench is rotationally connected to one side of the inflation valve provided with the connecting pipe, one end of the drive wrench located in the inflation valve is provided with a cam block, the cam block is located below the rocker plate, the cam block abuts against the bottom wall of the rocker plate, and the cam block drives the thimble to move towards the diaphragm after being rotated.

[0010] By adopting the above technical scheme, the rocker plate drives the thimble to move towards the diaphragm by rotating the drive wrench, so that the thimble pierces the diaphragm, the gas in the gas storage bottle enters the valve seat through the inflation valve, and then enters the air bag, thereby realizing inflation of the air bag, effectively preventing the pressing column from being stuck and unable to start, and improving the use stability of the inflatable life jacket.

[0011] Optionally, the outer wall of the inflation valve is provided with a buckle for fixing the drive wrench.

[0012] By adopting the above technical scheme, the buckle can effectively improve the stability of the drive wrench and prevent the drive wrench from rotating and causing the thimble to pierce the diaphragm.

[0013] Optionally, the outer wall of the opening of the gas storage tank is provided with external threads, the inner wall of the connecting pipe is provided with internal threads, and the gas storage tank and the connecting pipe are detachably connected through the external threads and the internal threads.

[0014] By adopting the above technical scheme, the gas storage tank and the connecting pipe are in the form of threaded connection, which facilitates quick assembly of the gas storage bottle, improves the efficiency during use, and also facilitates replacement of the gas storage bottle when the life jacket is recycled, while the buoyancy air bag and the folding air bag can continue to be used, thereby reducing the use cost and having high convenience and economic benefits.

[0015] Optionally, the drive pipe is provided with a protective cover.

[0016] By adopting the above technical scheme, the protective cover can prevent the pressing column from being accidentally touched, thereby preventing the rocker plate from rotating and causing the thimble to pierce the diaphragm, and preventing the folding air bag and the buoyancy air bag from being inflated in a state of not being used, thereby improving the stability of the inflatable life jacket and effectively reducing the waste of the gas storage bottle.

[0017] Optionally, the other buoyancy air bag is provided with a blowing pipe in communication with the buoyancy air bag.

[0018] By using the above technical scheme, the blowing pipe enables the user to blow air into the buoyancy air bag autonomously, so that the buoyancy air bag can maintain sufficient gas and thus ensure effective buoyancy, improving the safety and flexibility of use.

[0019] Optionally, the two buoyancy air bags are each provided with a buckle strap at the end close to each other.

[0020] By using the above technical scheme, the buckle strap enables the inflatable life jacket of the present application to be worn on the user more stably, thereby improving the stability during use.

[0021] In summary, the present application has at least one of the following beneficial technical effects:

[0022] 1. When the life jacket is not needed, no gas exists in the folding air bag and the buoyancy air bag, so that the folding air bag and the buoyancy air bag occupy a smaller volume, can be folded and stored in the waist bag, thereby facilitating the user to carry it on the body;

[0023] 2. The inflatable assembly of the present application is provided with two driving modes of driving wrench and pressing column, so as to ensure that the life jacket of the present application can normally inflate when needed, improving the stability of use. BRIEF DESCRIPTION OF DRAWINGS

In addition, the driving wrench 33 can be rotated, so that the cam block 331 rotates with the driving wrench 33, so that the flap 315 drives the thimble 312 to move towards the diaphragm 321, and then the thimble 312 pierces the diaphragm 321. The gas in the gas cylinder will enter the valve seat 21 through the inflating valve 31, and then enter the air bag, so as to realize the inflation of the air bag, and effectively prevent the pressing column 314 from being stuck and unable to start, and the life jacket cannot be normally used.

[0034] The above are the preferred embodiments of the present application, which do not limit the protection scope of the present application, therefore: any equivalent changes made on the structure, shape and principle of the present application shall be covered within the protection scope of the present application.
