Description

Balanced recoil buffer structure of automatic rifle

Technical Field

The invention relates to the technical field of rifle recoil, in particular to a balanced recoil buffer structure of an automatic rifle.

Background

In the conventional automatic rifle, taking AK107 as an example, a recoil spring of a counterweight piston is arranged right behind, but the recoil spring of a rifle bolt frame is squeezed to the left, the stress of a spring wire is larger, a recoil spring guide rod is thinner, and a transverse overturning moment is generated when the rifle bolt frame is pushed to recoil. In addition, the disassembly of the whole gun is troublesome, and the number of small parts is large.

The rifle has the advantages of complex structure, excessive parts, large recoil and excessive movable parts, can influence the precision of the rifle, increase the weight of the rifle and increase the fault probability.

Therefore, the problem which is mainly solved for improving the shooting precision of the automatic rifle is the problem of overlarge recoil when the automatic rifle is used for full-automatic shooting.

As an improvement, the front sealing cover is provided with an air hole.

As a modification, in the initial state, a gap is provided between the air guide piston and the deceleration piston connector.

As an improvement, a balance hedging structure is formed by the air guide collecting cylinders of the air guide pistons of the speed reducing pistons, high-pressure fuel gas can respectively apply pressure to the two pistons after entering the air guide collecting cylinders, the speed reducing pistons cannot move forwards due to the action of the front sealing covers and only can apply force to the upper surfaces of the air guide pistons, the air guide pistons push the gunlock to unlock, the unlocked gunlock drives the speed reducing pistons to move backwards, and due to the fact that a large amount of high-pressure gas still exists in the air guide cylinders, the gas delays the speed of a rear seat of the gunlock, and the gunlock cannot reach the bottom of the rear seat.

As an improvement, the connection of the bolt and the speed reduction piston is in a sliding connection mode, the connection is realized by pulling a bolt handle, the sliding distance is the unlocking distance of the air guide piston, and the air guide piston can only play a role after the bolt is unlocked.

Compared with the prior art, the invention has the advantages that: the air guide balance backseat principle solves the problem that the recoil of the automatic rifle during full-automatic shooting is too large, which affects the precision. The gas principle of ammunition is adopted as a deceleration and balance means. After the bolt is unlocked, a method of air guide delay is adopted, so that the reaction force during the backseat is increased, and the speed of the backseat of the bolt is reduced. The air guide balance structure is used, and the impact force brought by the gunlock rear seat to the shooter is buffered. So that the bolt carrier can not impact the bolt body.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

With reference to fig. 1-6, a balanced recoil buffer structure of an automatic rifle comprises a barrel 1, a decelerating piston 2, an air guide piston 3, a decelerating piston connector 4, a handle 5, a rifle bolt 6, a front sealing cover 7, an air guide collecting cylinder 8 and a rear sealing cover 9, wherein the air guide collecting cylinder 8 is connected and arranged above the barrel 1, the bottom of the front end of the air guide collecting cylinder 8 is communicated with the barrel 1 through an air guide hole 12, the front sealing cover 7 and the rear sealing cover 9 are respectively arranged at the front end and the rear end of the air guide collecting cylinder 8, the decelerating piston 2 is arranged in the air guide collecting cylinder 8 and close to the front sealing cover 7, the air guide piston 3 is nested at the rear end of the air guide collecting cylinder 8, a piston rod 11 is arranged on the decelerating piston 2, the piston rod 11 sequentially passes through the air guide piston 3 and the rear sealing cover 9 to be connected and arranged in the decelerating piston connector 4, the decelerating piston connector 4, the pulling handle 5 extends perpendicular to the surface of the bolt face 6 to the connecting piston rod 11 in the deceleration piston connector 4, and the bolt face 6 is connected and arranged at the rear end of the gun barrel 1 and the air guide collecting cylinder 8.

The front sealing cover 7 is provided with an air hole 12, a gap is formed between the air guide piston 3 and the speed reduction piston connector 4 in an initial state, a balance hedging structure is formed by the air guide piston 3 and the air guide collecting cylinder 8 of the speed reduction piston 2, the connection between the gun machine 6 and the speed reduction piston 2 is in a sliding connection mode, the connection is realized through the machine pulling handle 5, and the sliding distance is the unlocking distance of the air guide piston 3.
