[0002] About 372,000 people lose their lives due to drowning every year in the world. Drowning mainly occurs in rivers, lakes, reservoirs and other places. There is a risk of falling into the water when performing operations or activities near the water. Although many life-saving tools have emerged to deal with the risk of falling into the water, such as life buoys and life jackets, these life-saving tools are large in size, inconvenient to carry, and not conducive to activities. This is also the reason why many people are reluctant to carry life-saving tools in many cases. In order to solve this problem, it is necessary to provide a small and easy-to-carry life-saving pendant. Summary of the invention

[0003] In order to solve the above technical problems, the present invention provides a lifesaving pendant for people who fall into water.

[0005] As a further improvement of the above solution, a gas collecting sleeve is provided on the airbag, and the gas collecting sleeve is arranged on the trigger seat and connected to the air hole on the trigger seat, so that the gas in the gas tank can enter the airbag through the air hole.

[0006] As a further improvement of the above solution, a safety hoop is provided on the protective shell, and the safety hoop clamps the portion of the pull rope extending outside the trigger seat on the protective shell, so that when the pull rope is pulled, the safety hoop can be driven to detach from the protective shell.

[0007] As a further improvement of the above solution, the protective shell is composed of two half shells, so that after the safety hoop is detached, the protective shell without restriction can be split into two and fall off directly.

[0008] As a further improvement of the above solution, buckles are provided at the bottom of the two half shells, and the two buckles are snap-fitted with the protrusions at the bottom end of the gas tank, so as to limit the bottom of the protective shell and prevent the two half shells from separating.

[0009] As a further improvement of the above solution, the airbag is wrapped around the gas tank and the trigger seat in a Z-folded form, so that it can be smoothly stretched and formed after being inflated.

[0010] As a further improvement of the above solution, one end of the pull rope extending outside the trigger seat is connected to a whistle, so that the person who falls into the water can call for help by blowing the whistle, and the whistle also serves as a handle for pulling the pull rope.

[0011] As a further improvement of the above solution, a sling is provided at the bottom of the gas tank, a bracket with a hole is provided on one side of the protective shell, one end of the sling passes through the bracket with a hole and is provided with a hanging ring, so that the user can carry it more conveniently.

[0013] As a further improvement of the above solution, a sealing ring is sleeved on the rotor, and the outer ring of the sealing ring contacts the inner wall of the trigger seat, thereby satisfying the requirement of rotor rotation and ensuring sealing performance.

[0014] Compared with the prior art, the present invention has the following beneficial effects: The present invention integrates an air bag, an air tank for supplying air to the air bag, and a tank breaking mechanism for breaking the air tank to form a compact pendant-type life-saving tool for drowning. Compared with the existing life-saving tools for drowning, the pendant-type life-saving tool has the advantages of being small in size and easy to carry. The tank breaking mechanism is composed of a rotor, a pull rope, a thimble and other structures. The tank opening of the gas tank can be broken by pulling the pull rope. The mechanism cooperates with the gas tank and the air bag in a folded state, so that the lifesaving pendant can maintain a compact structure and be easy to carry under normal circumstances. When needed, the gas tank can be quickly broken to inflate the air bag, thereby integrating portability and practicality; The protective shell is composed of two half shells. When it cooperates with the safety hoop and the pull rope, the falling of the protective shell and the tank breaking mechanism form a linkage structure, so that when the user needs to use the life-saving pendant, he only needs to pull the pull rope to synchronously realize the falling of the protective shell and the breaking of the gas tank, and then automatically completes the inflation and molding of the air bag, thereby making the operation method simpler and more convenient without affecting the functionality of the life-saving pendant; The airbag is composed of multiple independent small airbags, and each small airbag is provided with a one-way valve, which can improve the safety of the airbag. Even if a hole appears in the airbag, it will not cause the entire airbag to leak and lose buoyancy, thereby improving the safety of the life-saving pendant. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0018] Please combine Figures 1 to 8 , a lifesaving pendant for falling into water, comprising: a gas tank 7 and a trigger seat 6 sleeved on the tank mouth of the gas tank 7, a top cover 1 is arranged on the top of the trigger seat 6, and at the same time, a positioning groove is arranged at the bottom of the top cover 1, and a positioning shaft is arranged on the top of the rotor 2, and the positioning shaft at the top of the rotor 2 extends into the bottom positioning groove of the top cover 1 and is rotatably connected thereto, so as to ensure the stability of the rotor 2 during rotation, the trigger seat 6 is a cylindrical structure, the lower half of which is an annular body, and the upper half is a tube body, and a thread is arranged on the inner ring of the annular body at the bottom, and a thread is also arranged on the tank mouth of the gas tank 7, and the two are threadedly connected and sealed by glue, air holes are arranged on both sides of the trigger seat 6, a tank breaking mechanism is arranged in the trigger seat 6, an air bag 8 is wrapped on the trigger seat 6 and the gas tank 7, and a protective shell 10 is arranged outside the air bag 8; The airbag 8 is composed of a plurality of independent small airbags, and each small airbag is provided with a one-way valve 16, so as to improve the safety of the airbag 8. Even if a hole appears in the airbag 8, it will not cause the entire airbag 8 to leak and lose buoyancy, thereby improving the safety of the lifesaving pendant. In addition, an auxiliary air guide rope 15 is also provided in the airbag 8, which leaves a gap in the airway of the airbag 8, so that the gas can smoothly enter the airbag 8 and then enter each small airbag; The can breaking mechanism includes a pin 5 threadedly installed in a trigger seat 6, a rotor 2 which can drive the pin 5 to rotate is arranged in the trigger seat 6, a pull rope 3 which can drive the rotor 2 to rotate is wound around the rotor 2, and pulling the pull rope 3 can drive the rotor 2 and the pin 5 to rotate, and a rope groove is arranged on the rotor 2, and the pull rope is wound around the rope groove, and the rope groove allows more space on the rotor 2 to accommodate the pull rope 3, and can also limit the wound pull rope 3 to prevent the pull rope 3 from being scattered, a thread is arranged on the inner wall of the trigger seat 6, and the pin 5 is composed of an octagonal column, a threaded column and a drill needle. The threaded column on the ejector pin 5 is threadedly connected to the trigger seat 6, and an octagonal groove is provided at the bottom of the rotor 2. The octagonal column at the top of the ejector pin 5 extends into the octagonal groove and is telescopically and slidably connected to the octagonal groove, so that the rotor 2 can not only drive the ejector pin 5 to rotate, but also enable the ejector pin 5 to drill through the mouth of the gas tank 7 by relying on the threaded rotation and descending while rotating. At the same time, the drill needle on the ejector pin 5 is a polygonal cone, which makes it easier to break the mouth of the gas tank 7 during rotation. A through hole is provided on one side of the trigger seat 6, and the pull rope 3 can extend to the outside of the trigger seat 6 through the through hole.

[0019] The airbag 8 is provided with a gas collecting sleeve 11 , which is sleeved on the trigger seat 6 and connected to the air hole on the trigger seat 6 , so that the gas in the gas tank 7 can enter the airbag 8 through the air hole.

[0020] The protective shell 10 is provided with a safety hoop 9, and the safety hoop 9 hoopes the portion of the pull rope 3 extending outside the trigger seat 6 on the protective shell 10, so that when the pull rope 3 is pulled, the safety hoop 9 can be driven to detach from the protective shell 10. In addition, the protective shell 10 is provided with a hoop groove and an N-shaped groove. The portion of the pull rope 3 clamped by the safety hoop 9 is N-shaped and is located in the N-shaped groove. The safety hoop 9 is sleeved in the hoop groove, so as to ensure the stability of the pull rope 3 and the safety hoop 9 and avoid the detachment of the two. The protective shell 10 is composed of two half shells, so that after the safety hoop 9 is detached, the protective shell 10 that loses its restriction can be split into two and fall off directly.

[0021] Through the above technical solution, since the protective shell 10 is composed of two half shells, when it cooperates with the safety hoop 9 and the pull rope 3, the falling of the protective shell 10 and the tank breaking mechanism form a linkage structure, so that when the user needs to use the life-saving pendant, he only needs to pull the pull rope 3 to simultaneously realize the falling off of the protective shell 10 and the breaking of the gas tank 7, and then automatically complete the inflation and molding of the airbag 8, thereby making its operation simpler and more convenient without affecting the functionality of the life-saving pendant.

[0022] Buckles are provided at the bottom of the two half shells, and the buckles on the two half shells have different heights, one above and one below, so that both can be snapped onto the protrusion at the bottom of the gas tank 7 without restricting each other. The two buckles are snapped onto the protrusion at the bottom of the gas tank 7, so that the bottom of the protective shell can be limited to avoid separation of the two half shells. In addition, the holes in the two buckles are elliptical, serving as redundant space, so that when the two half shells are separated, the buckles at the bottom will not be restricted by the protrusion at the bottom of the gas tank 7, causing the two half shells to be unable to be separated.

[0023] The airbag 8 is wrapped around the gas tank 7 and the trigger seat 6 in a Z-folded form, so that it can be smoothly stretched and formed after being inflated.

[0024] One end of the pull rope 3 extending outside the trigger seat 6 is connected to a whistle 12 , so that the drowning person can blow the whistle 12 to ask for help, and the whistle 12 also serves as a handle for pulling the pull rope 3 .

[0025] A hanging rope is provided at the bottom of the gas tank 7, and a bracket with holes is provided on one side of the protective shell 10. One end of the hanging rope passes through the bracket with holes and is provided with a hanging ring, so that the user can carry it more conveniently.

[0026] The upper and lower ends of the airbag 8 are respectively provided with a first force rope 13 and a second force rope 14, which are respectively wound around the trigger seat 6 and the protrusion at the bottom end of the gas tank 7, thereby improving the connectivity between the airbag 8 and the main structure of the life-saving pendant and ensuring the stability of the airbag 8.

[0027] The rotor 2 is provided with an annular groove for accommodating the sealing ring 4. The sealing ring 4 is sleeved in the annular groove on the rotor 2. The outer ring of the sealing ring 4 contacts the inner wall of the trigger seat 6, thereby satisfying the rotation requirement of the rotor 2 and ensuring the sealing performance.

[0028] The implementation principle of the water rescue pendant of the present application is: When the user needs to work or do activities near the water, he can carry the life-saving pendant with him; When the user falls into the water, he can hold the whistle 12 to pull the drawstring 3. After being stretched, the drawstring 3 will be separated from the N-shaped groove and straightened, and directly drive the safety hoop 9 to be separated from the protective shell 10. At this time, without the restriction of the safety hoop 9, the protective shell 10 will spread from the top to the two sides, thereby achieving the shedding of the protective shell 10; At the same time, when the pull rope 3 is pulled, it will drive the rotor 2 to rotate, and the rotor 2 will drive the thimble 5 to rotate. Under the action of the thread, the thimble 5 will move downward when rotating until it drills the mouth of the gas tank 7. Subsequently, the gas in the gas tank 7 will enter the trigger seat 6 and enter the air bag 8 through the gas collection sleeve 11 along the air hole, so that the air bag 8 will expand and become a floating object to provide buoyancy for the drowning person.

[0029] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
