Structure of life jacket

Abstract

A life jacket structure includes a life jacket body, at least one set of hanging devices, a blowing tube and an inflation starting device. An inflatable airbag is sewed onto an internal side of the body, and the body further includes at least one pair of strap holes disposed on corresponding position on both sides. Both ends of the hanging device are connected onto the corresponding strap holes of the life jacket. The blowing tube is installed at an appropriate position of the life jacket body and penetrated through the life jacket into the inflatable airbag. The inflation starting device is installed on the life jacket and disposed on the same side of the blowing tube, and further includes an inflation cylinder and a starting mechanism. The starting mechanism is provided for receiving a start signal to start inflating the life jacket by the inflation cylinder.

1 . An improved structure of a life jacket, comprising:
 a life jacket body, with an internal side sewed into an inflatable airbag, and the life jacket body having at least one pair of strap holes disposed at corresponding positions on both lateral sides of the life jacket body;   at least one set of hanging devices, with at least two ends, and the first end being linearly fixed into the first hanging hole of the life jacket body, and the second end being linearly fixed into the second hanging hole of the life jacket body;   a blowing tube, installed at an appropriate position of the life jacket body, and penetrated through the life jacket body into the inflatable airbag, such that air can be blown through the blowing tube into the inflatable airbag for inflating the inflatable airbag; and   an inflation starting device, installed on the life jacket body, and disposed on the same side of the blowing tube, and the inflation starting device comprising:   an inflation cylinder; and   a starting mechanism, installed at an appropriate position of the life jacket body, and coupled to the inflation cylinder, for receiving a start signal to start the inflation cylinder to inflate the life jacket body.   
   
   
       2 . The improved structure of a life jacket of  claim 1 , wherein the life jacket body is made of a light, thin, water-proof and wind-proof material, and the life jacket body has a foldable, rollable and deformable feature. 
   
   
       3 . The improved structure of a life jacket of  claim 1 , wherein the set of hanging devices is a hanging strap. 
   
   
       4 . The improved structure of a life jacket of  claim 3 , wherein the hanging strap further comprises:
 at least two connecting elements, installed on two distal surfaces of the hanging strap, and corresponding to the pair of strap holes of the life jacket body, for coupling the hanging strap with the life jacket body; and   an adjusting element, for adjusting the length of the hanging strap.   
   
   
       5 . The improved structure of a life jacket of  claim 4 , wherein the connecting element of the hanging strap is a connecting structure selected from the collection of an elastic latch, a button, a hanging hook, a knot, and a Velcro tape. 
   
   
       6 . The improved structure of a life jacket of  claim 1 , wherein the starting mechanism of the inflation starting device further includes a pull ring provided for a user to pull and generate the start signal of the starting mechanism.
