Life jacket with automatic inflating and tightening buoyancy device

Abstract

The invention relates to the technical field of marine lifesaving, in particular to a life jacket with an automatic inflating and tightening buoyancy device, which comprises a lifesaving vest, a buoyancy foam block sewn on the outer side surface of the lifesaving vest and an automatic inflating device. According to the life jacket with the automatic inflating and tightening buoyancy device, a bottom supporting cover internally provided with an inflating air bag is connected to a bottom bandage at the lower end of a life vest, annular inner air bags are sewn to the inner sides of arm wearing openings in the two sides of the life vest, the supporting area of the bottom of a wearer is increased, and meanwhile the annular inner air bags expand and extrude out; an internal opening of the arm wearing opening is tightened, so that the wearing comfort is improved while the wearing stability of a person is ensured; solid sealing liquid is inserted into the connecting end of the internal air delivery pipe, and the solid sealing liquid is fused with water to form a cementing substance through automatic water encountering or manual pressing, so that the damaged end of the air bag is sealed and plugged, air leakage is avoided, and the safety of the life jacket is greatly improved.

Description

technical field [0001] The invention relates to the technical field of marine lifesaving, in particular to a lifejacket with an automatic inflation tightening buoyancy device. Background technique [0002] Life jacket, also known as life vest, is a life-saving clothing designed similar to a vest, made of nylon fabric or neoprene (NEOPRENE), buoyancy material or inflatable material, reflective material, etc. The general service life is 5-7 years, and it is one of the life-saving equipment on ships and planes. It is generally a vest type, made of foam plastic or cork. It has enough buoyancy when worn on the body, so that the head of the person who falls into the water can come out of the water. [0003] However, the current life jackets on the market are simple in structure and have a single function. In order to improve the stability after wearing, it is necessary to install straps at the bottom, but the straps installed at the bottom do not have an adjustable storage mecha...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is: in order to solve the problems existing in the above-mentioned background technology, provide an improved lifejacket with automatic inflation tightening buoyancy device, solve the problem that the lifejackets currently on the market are simple in structure and very single in function, in order to improve For stability after wearing, straps need to be installed at the bottom, but there is no adjustable storage mechanism for the straps installed at the bottom, which leads to long-term dragging on the outside and serious wear and tear. Moreover, during use, the buoyancy of the life jacket will be carried out through the arm connection. Pulling, resulting in relatively large friction at the arm end, poor comfort, and at the same time, once the inflatable airbag of the life jacket is damaged, it cannot be used, resulting in a problem of low safety
