Description

Continuous firing of the barrel rear seat type automatic weapon circulation shooting mechanism

This creation is a mechanical structure module that allows automatic weapons to have continuous shooting capabilities.

The Benelli shotgun of Italy uses Inertia driven inertial drive technology to shoot semi-automatic shots. The principle of action is: the gun pushes the bullet into the lock, the shooter releases the hammer, the hammer strikes the shot, the shot hits the impact. After the ammunition primer ignites the propellant, the high-pressure gas pusher pops out the muzzle, and the rear seat force is generated, which instantly pushes the whole body of the gun body (except for the components other than the gun, including the barrel, the bolt, the gun body, and the buttstock). ...etc.) and the shooter's body is backwards, the mass inertia of the gun is still in place, and the overall body of the gun body compresses the high-strength spring (gun spring) between the bolt and the gun to store energy, and then the gun spring releases energy. The gun machine, after the gun receives the energy, presses the hammer to rotate downward, and presses the recoil spring to travel backwards, and at the same time drives the rear end of the gun to complete the unlatching and shelling action. When the recoil spring bears and consumes the rear seat force of the gun, the recoil spring re-bounces and pushes the gun forward. The gun pushes the bolt to complete the push (in) bomb, and the bolt and the barrel sleeve are combined and locked, and the whole gun is Presented in a ready state. The use of this principle is limited to the implementation of semi-automatic shooting (only one shot can be fired once in a single trigger), and continuous shooting cannot be performed automatically (the trigger can not be continuously shot). This principle does not fix the gun body on the tripod. In the case of obstacles behind the gun, it will not be possible to shoot (the Inertia driven inertial drive system may fail due to the fact that the gun body cannot be instantaneously seated after the shot) .

In view of the shortcomings of the above-mentioned Inertia driven inertial drive technology, the present invention provides a mechanism for automatically firing a barrel rear seat type weapon, which can implement automatic shooting, and the gun body can be installed on any gun frame for fixed use without the space behind the gun. The limitation is a new principle of continuous firing of the barrel rear seat type automatic weapon cycle shooting mechanism.

In view of the above-mentioned Italian Innovative driving technology of Benelli shotgun Point, the main purpose of this creation is to provide a new principle of continuous shooting automatic weapon mechanism. When the barrel is fired, the rear seat is instantaneously generated, and the motive force is generated to drive the rear seat of the gun to achieve continuous shooting and no shooting space. The limit of the way (such as tripod shooting).

For the above purposes, the creative department provides a new type of continuous firing gun barrel The seat type automatic weapon circulation shooting mechanism comprises a barrel group with an ammunition firing to provide a warhead to accelerate forward, and a barrel to retreat, a gun unit with a high rigidity spring (gun spring) and a bolt bolt, and an ammunition The firing pin group of the firing function has a reversing spring seat group that provides a recoil cushioning and a re-entry function. The barrel assembly includes a barrel, a barrel spring and a barrel sleeve, and the gun unit includes a gun bolt, a gun machine and a gun spring. The needle group includes a needle, a needle spring and a needle top. The rod and the like comprise a unit, and the reversing spring seat group comprises a composite spring seat, a buffer spring and a recoil spring. The single cycle operation of the automatic cycle shooting mechanism is as follows: the gun unit stays at the rear end of the gun, the shooter pulls the trigger, releases the gun unit forward, pushes the B-arm ammunition into the magazine, and after the ammunition is fired, the gun of the barrel is instantly The sleeve unit is combined with the lance unit of the gun unit and the rear seat. The gun spring unit of the compression gun unit stores energy, and then the gun spring unit releases energy to push the gun unit, and the gun unit receives energy and compresses the retracting spring seat. The group travels backwards, and at the same time drives the rifle unit to complete the unlatching and shelling action. After the recoil spring unit and the buffer spring unit withstand and consume the rear seat force of the gun unit, the re-feed spring unit rebounds to push the re-entry spring unit and the gun unit forward, and the push-pull unit completes the push and the spring action. Finally, the breech block and the barrel sleeve unit are combined and locked, and the secondary munition is fired by the ejector pin and the squeezing unit, and the barrel and the rifle unit are simultaneously at the same time in the rear seat, so that the barrel rear seat weapon is automatically continuous. The purpose of shooting.
