Air pistol constant pressure device

Abstract

An air pistol constant-pressure device comprises an air bottle connecting base and a pressure reducer body connected with the air bottle connecting base. A cavity I and a cavity II are formed in the air bottle connecting base and the pressure reducer body respectively. After the air bottle connecting base and the pressure reducer body are connected, an air supply chamber is formed by the cavity I and the cavity II. A disc spring and a piston are arranged in the air supply chamber. It can be guaranteed that the amount of bullets shot in a competition or training meets a competition standard, air pressure is constant every time the bullets are shot, and therefore the shooting accuracy is guaranteed. In addition, a special exhaust channel is arranged, after the competition is finished and an air bottle is detached, redundant high-pressure air in the air supply chamber and a pressure stabilizing chamber can be exhausted without redundancy, the condition that an air pistol can be used for shooting after the air bottle is detached is avoided, and potential safety hazards are eliminated. The air pistol constant-pressure device is simple and compact in structure, convenient to install and stable in performance.

Description

technical field [0001] The invention relates to an air pistol for competitions, in particular to a constant pressure device for an air pistol for competitions. Background technique [0002] In the air pistol shooting competition, 60 rounds of ammunition must be fired within the specified time. Due to the time limit, this requires that a gas cylinder must be able to meet more than 60 rounds of shooting when it is full of gas. However, as the shooting progresses, the gas in the cylinder is gradually consumed and the pressure continues to decrease. If the working pressure is not kept constant through a device, the air pressure of each shot is determined by the pressure of the cylinder. When the cylinder is filled with gas , the working pressure is high, and the working pressure will decrease when the gas is gradually consumed, and the unstable working pressure will greatly affect the shooting accuracy. At the same time, during training, if the gas needed to shoot a bullet is m...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the technical problem in the prior art that affects the shooting accuracy due to the unstable pressure of the gas cylinder during use, further, in order to solve the technology in the prior art that the residual gas in the gas chamber causes safety hazards after the gas cylinder is removed Problem, the purpose of this invention is to provide a constant pressure device for an air pistol, which can ensure a constant pressure for each shot, thereby ensuring shooting accuracy
