Segmented tube recoil barrel

By using a segmented barrel recoil design, the front fixed barrel remains stationary before the projectile leaves the barrel, while the rear moving barrel recoils independently. This solves the problems of shooting accuracy impact and high manufacturing difficulty caused by the recoil of traditional gun barrels, achieving a reduction in mass and a buffering effect.

AI Technical Summary

Technical Problem

Traditional recoil-operated gun barrels suffer from problems such as reduced shooting accuracy due to the recoil of the entire barrel, high weight, and high manufacturing difficulty.

Method used

It adopts a segmented tube recoil design, with the front fixed tube body and the rear moving tube body separated. The front fixed tube body remains stationary before the projectile leaves the barrel, while the rear moving tube body recoils independently to buffer the recoil force.

Benefits of technology

This achieves the goal of reducing barrel weight and manufacturing difficulty while maintaining shooting accuracy, and lowers the requirements for the buffer mechanism.

Abstract

The application relates to a segmented tube recoil rifle barrel in the field of weapon equipment technology, which comprises a front fixed barrel body rigidly connected with a frame and a rear movable barrel body coaxially inserted into a sleeve cavity at the rear end of the front fixed barrel body. The rear movable barrel body can move rearward along the axis under the action of gunpowder gas, so that the barrel is segmented and the recoil is buffered; and the front fixed barrel body remains static before the bullet is fired, so that disturbance to the bullet posture is avoided. The application is mainly applied to various rifles, and is especially suitable for automatic weapons which need to reduce the recoil and improve the shooting precision. Compared with the existing whole-recoil tube recoil rifle barrel, the application has the advantages of simple structure, significantly reduced recoil, obviously improved shooting precision and convenient maintenance.

Description

Technical Field

[0001] This invention belongs to the field of weaponry technology, specifically relating to a segmented recoil barrel for firearms. Background Technology

[0002] The automatic operating principles of existing firearms are mainly divided into gas-operated, recoil-operated, and bolt-operated. Recoil-operated firearms utilize propellant gases to propel the entire barrel backward, driving the automatic mechanism to complete the cycle. Typical recoil-operated weapons include the Browning Auto-5 shotgun and the M82 sniper rifle, whose common feature is the recoil of the entire barrel. However, traditional recoil-operated barrels have the following drawbacks: the recoil of the entire barrel causes a change in the barrel position before the bullet leaves the barrel, affecting shooting accuracy; the overall barrel mass is large, resulting in high recoil energy and demanding requirements for the buffer mechanism; the long mating surface between the barrel and the receiver makes manufacturing difficult. Therefore, a new barrel structure is needed that can both utilize the recoil principle to buffer recoil force and avoid the impact of the entire barrel's recoil on accuracy. Summary of the Invention

[0003] A segmented recoil-type barrel includes a front fixed barrel and a rear moving barrel. The front fixed barrel is rigidly connected to the frame and has a fitting cavity at its rear end; the front end of the rear moving barrel is coaxially inserted into the fitting cavity and can move axially backward, so that the front fixed barrel remains stationary before the projectile leaves the barrel to avoid disturbing the projectile, while the rear moving barrel recoils independently to buffer the recoil force.

Claims

1. A segmented recoil-type gun barrel, characterized in that: The front fixed tube has a fitting cavity at its rear end; the front end of the rear moving tube is coaxially inserted into the fitting cavity and can move axially backward relative to the front fixed tube.
