A practice gun for shooting sports

Abstract

The invention provides an exercise gun for shooting, and belongs to the technical field of gun equipment. The exercise gun comprises a gun body, a gun barrel and a gun stock; the gun barrel is connected with the gun stock through the gun body, and the front end of the gun barrel is provided with a muzzle; a muzzle brake is installed on the muzzle and comprises a brake chamber of a box-body structure; the left side wall and the right side wall of the brake chamber are provided with first exhaust holes, the position, away from the muzzle, of the front wall of the brake chamber is provided with athrough hole, and the through hole and the muzzle are coaxial; the left side wall and the right side wall of the brake chamber are provided with air collecting covers; the two first exhaust holes correspond to the two air collecting covers one by one, and the air collecting covers are located on the outer sides of the corresponding first exhaust holes; the lower side surface of the gun body is provided with an air collecting box through a bracket, an installation cavity is formed in the air collecting box, and the two air collecting covers communicate with the installation cavity through airconveying pipes; and the air collecting box is provided with a power generation device which conducts power generation through explosive fuel gas exhausted through the muzzle brake. According to the exercise gun for shooting, the recoil of the gun can be reduced, and meanwhile, the exercise gun can generate power and is environmentally friendly.

Description

technical field [0001] The invention belongs to the technical field of gun equipment, and relates to a practice gun used for shooting sports. Background technique [0002] When a firearm fires a bullet, the bullet shell is subjected to the impact pressure of the gunpowder gas, thereby pushing the gun body to recoil, and the recoiled gun body hits the butt, generating recoil force. Theoretically, the larger the caliber, the harder the impact, and the greater the recoil force. [0003] Muzzle brakes have been used in most existing firearms to reduce recoil. The principle of the muzzle brake is to control the flow ratio of the gunpowder gas through the central bullet hole and the side hole during the aftereffect period in different structural forms, and to control the flow rate of the side hole. The direction and speed of the hole airflow can reduce the recoil energy of the gunpowder gas to the firearm in the way of momentum transfer. The gunpowder gas sprayed behind the muzzl...

AI Technical Summary

Problems solved by technology

The gunpowder gas sprayed behind the muzzle brake will generate a large impact energy, but there is no corresponding buffer device on the existing muzzle brake, so that the impact energy may cause damage to the shooter, and the impact energy is not used reasonably
