Abstract

A general cartridge receiver assembly for front-air-guide firearms is characterized in that a gun barrel is arranged in a cartridge receiver, an air guide protection bush is arranged on the lower side of the front end of the cartridge receiver, a piston rod is arranged in the air guide protection bush, a piston is arranged at the front end of the piston rod, a cavity air guide chamber is reserved on the rear side of the piston, a communication air guide hole is formed between the gun barrel and the air guide chamber, a connecting rod and a firearm bolt shifting rod are arranged at the rear end of the piston rod, a reset spring is arranged on the firearm bolt shifting rod, a firearm bolt is arranged on the rear side of the upper end of the firearm bolt shifting rod, and a cartridge holder is arranged on the lower side of the firearm bolt. An axial firearm bolt spring is arranged on the rear portion of the firearm bolt, an axial firearm bolt lock is arranged in the firearm bolt, an axial firing pin is arranged in the firearm bolt lock, a firing hammer is arranged at the position, arranged at the rear end of the firing pin, of the rear side of the firearm bolt, and a firing gear is arranged at the lower end of the firing hammer. A front-arrangement pushing rod is arranged on the right side of the lower portion of the firing gear, and a trigger is arranged at the front end of the pushing rod. The problem that when a rear-air-guide type firearm performs shooting, a back seat of the firearm bolt affects the firing accuracy is solved, and the general cartridge receiver assembly is suitable for being used by the manufactured firearms such as rifles and submachine guns.

Description

technical field [0001] The invention relates to the field of design and manufacture of firearms, in particular to a common casing structure for firearms. Background technique [0002] The current gas-guiding firearms with support and no support design all adopt the rear gas-guiding structure, and the accessories cannot be interchanged for common use. Because the gunpowder gas pushes the piston when shooting, the piston pushes the rear seat of the bolt, and the rear seat of the bolt violently hits the machine. The box is used to shoot people, which seriously affects the shooting accuracy. Contents of the invention [0003] The invention aims to solve the problem that the back seat of the gun bolt affects the shooting accuracy when the accessories are not universally used for firearms designed with and without the rear gas guide, and designs a universal casing for the firearm with the front gas guide structure. [0004] The technical solution of the present invention is a u...
