Life jacket with alarming and positioning functions

Abstract

The invention relates to a life jacket with alarming and positioning functions. The life jacket comprises a jacket body, a connecting cover, a mounting plate, a positioner, an expansion assembly, rearshoulder straps and a power supply. A mounting groove for mounting the mounting plate is formed in the connecting cover; the positioner is electrically connected with the power supply, and the positioner and the power supply are both arranged on the mounting plate; the mounting plate is provided with an inflating disc capable of releasing gas when being impacted; and an air outlet end of the inflating disc is communicated with a first mounting cover and a third mounting cover. The expansion assembly comprises the first mounting cover, a first expansion air bag, a second mounting cover, the third mounting cover and a second expansion air bag. The first mounting cover and the second mounting cover are connected to form a cover body; the cover body is filled with the first expansion air bag;the rear shoulder straps are connected to the shoulders of the jacket body and provided with warning lamps electrically connected with the power supply. The personnel can trigger the inflation disc to inflate by patting the life jacket so as to provide buoyancy; the warning effect of the warning lamp is better, and the life jacket has a positioning function and facilitates accurate search and rescue of the search and rescue personnel.

Description

technical field [0001] The invention relates to the technical field of life jackets, in particular to a life jacket with an alarm and positioning function. 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 material, buoyancy material or inflatable material, and reflective material. The general service life is 5-7 years, and it is one of the life-saving equipment on ships and planes. Life jackets are generally vest-style and 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] For lifejackets with buoyancy materials, the volume is large; for lifejackets that can be inflated by inflation, the volume is small. Generally, the inflator inflates the airbag by pulling the drawstring on the inflator to generate buoyancy. However, the personnel wearing the lifejacke...

Problems solved by technology

[0003] For lifejackets with buoyancy materials, the volume is large; for lifejackets that can be inflated by inflation, the volume is small. Generally, the inflator inflates the airbag by pulling the drawstring on the inflator to generate buoyancy. However, the personnel wearing the lifejacket It is not easy to pull the pull rope, so that the personnel cannot conveniently and directly trigger the inflator to inflate the airbag, and the existing life jackets generally only have reflective strips, the warning function is limited, and there is no positioning function, which has certain limitations
