Sensing type air guiding device

Abstract

The invention provides a sensing type air guiding device. The sensing type air guiding device comprises a gun barrel, a sensing air hole, a sensing piston, an openable and closable air guiding hole and a bullet return piston. The gun barrel is provided with the sensing air hole and the openable and closable air guiding hole. The sensing air hole is formed in the position, close to a muzzle, of thefront end of the gun barrel. The sensing air hole communicates with a sensing air cylinder parallel with the gun barrel. The sensing piston comprises a first end and a second end. The first end is arranged in the sensing air cylinder and moves back and forth in the sensing air cylinder. The second end is in contact with a reset spring, and under push of the reset spring, the sensing piston has thrust for moving toward the muzzle. According to the sensing type air guiding device, the design of a sensing system is adopted, and under the circumstance that a counter-recoil cycle is guaranteed, the firing range is increased; and the balancing problems of the counter-recoil cycle and sealing design in the traditional air hole design process are solved.

Description

technical field [0001] The invention relates to the field of firearms, in particular to a sensor-type air guiding device. Background technique [0002] Most of the modern automatic firearms adopt the principle of air-guiding. The principle is to use the high-pressure gas produced by the combustion of the propellant in the projectile to push the projectile to accelerate in the barrel, and the gas passes through the air hole on the barrel to push the structure connecting the bolt, such as the piston and the piston connecting rod, or Conduit and supercharger to complete the automatic process of unlocking, shell extraction, shell feeding and locking. [0003] The position of the air guide hole, the diameter and the performance of the gunpowder determine the time relationship between the projectile leaving the muzzle and unlocking. The prior art has the following two structures: [0004] 1. The piston transmission structure consists of an air guide hole, a piston, a piston conn...

Problems solved by technology

[0008] Since the diameter of the air duct must be kept small enough to allow the high-pressure gas to maintain enough pressure to blow the bolt, if the quality of the propelling powder of the projectile is not good, it will easily cause serious carbon deposits in the air duct and the bolt, which will easily lead to failure of the bolt. Normal operation, insufficiency occurs
