Lifesaving gun for drowning people

Abstract

The invention provides a lifesaving gun for drowning people. The lifesaving gun comprises a trigger, a gun body, a spring compression disc, a bullet, an impact spring and a gunsight. The structure of the lifesaving gun is characterized in that a handle of the gun body is provided with the trigger, the trigger is connected with the spring compression disc arranged at the central part of the gun body, one end of the impact spring is connected with the spring compression disc, the other end of the impact spring abuts with the bullet, and the gunsight is connected with the front end of the gun body. The bullet is composed of a bullet body and an elastic lifebuoy; and the bullet body is composed of a bullet head, a foaming medicine bag, a gas-guide tube, a minisized motor, a crank connecting rod, a time delay relay, a sealed pipe and an impact switch. The lifesaving gun provided by the invention is small-sized emergency drowning lifesaving equipment which has the advantages of a compact light structure, convenience in use, usage of an electromagnetic time-delay function, adoption of chemical foaming, a fast reaction speed, accurate launching of the lifesaving bullet to drowning people, fast inflation of the lifebuoy and great popularization and application values.

Description

technical field [0001] The invention relates to a drowning lifesaving gun. Background technique [0002] Water sports are people's favorite sports in summer, including swimming, diving and boating. Because water sports are dangerous, people generally take necessary anti-drowning measures, such as life buoys, life jackets and other equipment, but these measures are limited It is very large, which also makes the annual death toll of water sports far higher than that of car accidents. Generally, people who can swim are mostly drowned due to physiological factors such as cramps, while those who can't swim are the reaction of protective measures. Slowness or its own factors, so the lack of current water sports protection measures and the singleness of protective equipment make this kind of sports still very dangerous. The current protective equipment is very passive when used, and the response is also very slow. It is troublesome to operate and use. It is impossible to rescue th...

[0002] Water sports are people's favorite sports in summer, including swimming, diving and boating. Because water sports are dangerous, people generally take necessary anti-drowning measures, such as life buoys, life jackets and other equipment, but these measures are limited It is very large, which also makes the annual death toll of water sports far higher than that of car accidents. Generally, people who can swim are mostly drowned due to physiological factors such as cramps, while those who can't swim are the reaction of protective measures. Slowness or its own factors, so the lack of current water sports protection measures and the singleness of protective equipment make this kind of sports still very dangerous. The current protective equipment is very passive when used, and the response is also very slow. It is troublesome to operate and use. It is impossible to rescue the drowning person in time, and there are similar throwing lifesaving devices at present, such as a lifesaving throwing device disclosed in Patent No. 200420024242.6. This type of device has the advantage of fast lifesaving speed, but the current design is very unscientific , using gas cylinders, pressure gauges and other mechanical designs, it is very error-prone and the volume is very large, so it cannot be widely used
