Problems solved by technology

[0002] In the process of water rescue, life jackets, life belts and life buoys are indispensable tools, but the general life jackets, life belts and life buoys are filled with gas before use, resulting in the large size of such life saving tools, which is inconvenient Carrying and taking up a lot of space, it is easy to bring some inconvenience to the user during the wearing process, such as the phenomenon that the life jacket looks very bulky when worn.
[0003] In the prior art, there are life preservers that can be automatically inflated when drowning, but the contact surface between this type of life preserver and the water body is relatively fixed, and the resulting buoyancy is relatively fixed. If the user who is overweight wears it, it may cause The life-saving effect is not ideal. Moreover, when the user wears this type of life jacket in the water, the center of gravity is low, and the entire lower body is completely immersed in the water body. function, which is not conducive to practical use, let alone in the long-term rescue process

Embodiment 1

[0032] Such as Figure 1 to Figure 5 As shown, the self-inflating inflatable lifeguard in this embodiment includes a lifejacket main body, and two front body airbags 3 are fixedly installed on the front surface of the lifejacket main body, and the two front body airbags 3 are connected by a waterproof zipper 7. The surface of the airbag 3 is divided into four regional airbags, and the interior of the regional airbags is connected by a one-way valve. And the three regional airbags are connected by a one-way valve, and the surfaces of the front body airbag 3 and the rear body airbag 13 are all equipped with a connecting mechanism, and the connecting mechanism and the inside of the front body airbag 3 and the rear body airbag 13 are connected and connected. The surface of the mechanism is fixedly equipped with an automatic inflation mechanism, which can fill the interior of the front airbag 3 and the rear airbag 13 with gas at the moment when the lifeguard touches the water body,...

Embodiment 2

[0040] The structure of the water self-inflating inflatable life preserver of this embodiment is basically the same as that of the water self-inflating inflatable life preserver in Embodiment 1, the difference being that two binding cassettes 20 are installed on the inner surface of the rear airbag 13 , the inner surfaces of the two predecessor airbags 3 are all equipped with two high-fiber pull rings 21 (see Figure 6 ). The fastening performance of the binding cassette 20 is good, and it can bind the human body when wearing it, so as to increase the connection effect between the entire life preserver and the human body. The high-fiber pull ring 21 is made of a flexible high polymer, such as Ultra-high molecular weight polyethylene fibers, etc., are convenient for manual application of tension during the entire lifesaving deployment process.

[0041] The use method of this embodiment is: before actual use, the user can bind the binding cassette 20 on the body when wearing it...

Embodiment 3

[0043] The structure of the water self-inflating inflatable life preserver of this embodiment is basically the same as the structure of the water self-inflatable inflatable life preserver in Embodiment 1 or 2, the difference being: the surface of the rear air bag 13 below the second gas cylinder 10 Telescopic floating rods 23 are fixedly installed, that is, two telescopic floating rods 23 are hollow inside and are made of high-quality carbon fiber materials, and the two ends of the telescopic floating rods 23 extend outwards and are connected by rods of different thicknesses. It has a telescopic function, and the surface of the predecessor airbag 3 on one side of the first gas cylinder 2 is fixedly equipped with two insert rings 22, which are made of general nylon cloth ( Figure 7 ). In actual use, when the two predecessor airbags 3 are deployed in the forward direction, the insert ring 22 and the telescopic floating rod 23 are at the same level.

[0044] The use method of t...

Abstract

The invention discloses a water-meeting self-filling type air inflatable life-saving apparatus. The water-meeting self-filling type air inflatable life-saving apparatus comprises a life vest main body, wherein two front airbags are fixedly mounted on a front-end surface of the life vest main body; the two front airbags are connected through a waterproof zip fastener; a rear airbag is mounted on arear-end surface of the life vest main body; connection mechanisms are mounted on surfaces of the front airbags and the rear airbag; an automatic inflation mechanism is fixedly mounted on the surfaceof each connection mechanism; an expanding mechanism is mounted on a bottom-end surface of the life vest main body; an auxiliary extending mechanism is fixedly mounted at each of the bottom end of theexpanding mechanism and the top end of the rear airbag. A folding mechanism is mounted at the bottom end of the rear airbag. According to the water-meeting self-filling type air inflatable life-saving apparatus, a series of structures are arranged, so that the life-saving apparatus can realize automatic inflation and is easy to wear; the life-saving apparatus can be used for supporting a whole body of a user to lift the gravity center, so that the whole body is prevented from being immersed in a water body for a long period and the utilization effect of a life raft can be realized, and furthermore, self-saving is convenient to realize and a cyclic air inflation function is realized.

Description

technical field [0001] The invention relates to the technical field of lifesaving on water, in particular to a self-filling inflatable lifesaving device when encountering water. Background technique [0002] In the process of water rescue, life jackets, life belts and life buoys are indispensable tools, but the general life jackets, life belts and life buoys are filled with gas before use, resulting in the large size of such life saving tools, which is inconvenient While it takes up a lot of space to carry, it is easy to bring some inconvenience to the user during the wearing process, such as when the life jacket is worn, it seems very cumbersome and the like. [0003] In the prior art, there are life preservers that can be automatically inflated when drowning, but the contact surface between this type of life preserver and the water body is relatively fixed, and the resulting buoyancy is relatively fixed. If the user who is overweight wears it, it may cause The life-saving...
