Sensing air guide

Abstract

The invention provides a sensor-type air guiding device, comprising: a gun barrel, a sensing air hole, a sensing piston, an openable and closable air guiding hole and an ejection piston. The air hole, the sensing air hole is located at the front end of the gun barrel, close to the muzzle position, the sensing air hole communicates with the sensing cylinder parallel to the gun barrel; the sensing piston includes a first end and a second end , the first end is set in the sensing cylinder, and moves back and forth in the sensing cylinder, the second end is in contact with a return spring, and under the push of the return spring, the sensor The sense piston has a thrust to move towards the muzzle direction. The sensor-type air-guiding device of the present invention adopts the design of the sensor system, increases the shooting range under the condition of ensuring the re-entry cycle, and solves the trade-off problem between the re-entry cycle and the sealing design of the traditional air hole design.

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
