Disclosure of Invention
An object of the utility model is to provide a life vest convenient to carry, hand-carry life vest can help people to open the life vest fast under the proruption situation (like flood, pleasure boat) and put on, thereby improve the survival rate greatly.
The utility model discloses an aim at and solve its main technical problem and adopt following scheme to realize:
the utility model provides a portable life vest, includes the life vest main part, the life vest main part is vest formula, divides anter and back part, and two about the life vest main part anter divides, and life vest main part back part is equipped with button trigger device, and button trigger device is connected with the gas reaction bag, the gas reaction bag is connected including sodium azide and tungsten filament, adopts NaN 3 =Na+N 2 The nitrogen gas filled in the gas is rapidly prepared according to the reaction principle, and the button trigger device and the gas reaction bag are electrically connected with a power supply; the left and right sheets of the front piece of the life jacket main body are provided with a plurality of rows of connecting buckles, and one row of the connecting buckles are connected with hanging buckles.
Furthermore, the life jacket main body is made of polyethylene foam or chloroprene rubber.
Further, the connecting buckles are arranged in at least three rows.
Furthermore, the connecting buckle is a common plastic buckle.
Furthermore, the button trigger device adopts a physical pressing type structure, and the tungsten filament is quickly heated by pressing to switch on a power supply so as to trigger the sodium azide reaction of the gas reaction bag.
Furthermore, the hanging buckle is made of stainless steel.
The life jacket main body of the utility model is provided with the connecting buckle, and the life jacket main body can be bundled by the connecting buckle in the compressed and folded state and can be carried about; when in use, the connecting buckle is unfastened, the power supply is switched on by pressing the button trigger device to ensure that the tungsten filament is quickly heated to trigger the reaction, and NaN is adopted 3 =Na+N 2 The nitrogen gas as the filling gas is quickly prepared according to the reaction principle, the life jacket can be instantly inflated, and the life jacket main body is fixed on the body by using the connecting buckle after the life jacket is inflated.
The utility model discloses the appearance is succinct light, about 25 cubic centimeters, can hand-carry, can do the key ring, and cell-phone shell pendant, user carelessly drowned can become rapidly wearable life vest that can grasp with the hand through touching aerating device to save life. The lifesaving problem in case of sudden drowning is well solved, and mass production can be realized.
