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

The invention is a mechanical structure module which can make an automatic weapon have a continuous shooting function.

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: 1. Only semi-automatic shooting can be implemented (the trigger can only shoot 1 round in one shot), and continuous shooting cannot be performed automatically (the trigger can not be continuously shot). 2. This principle can't fix the gun body on the tripod. If there is an obstacle behind the gun, it will not be able to shoot. (Because the gun body can not be instantly back seated after the shooting, the inertia drive principle is invalid.)

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

In view of the shortcomings of the Inertia driven inertial drive technology of the above-mentioned Italian Benelli shotgun, the main purpose of the present invention is to provide a new principle of the action of the continuous shooting automatic weapon mechanism, which is generated by the moment of the rear seat of the barrel when the barrel is fired to generate the motive force to drive the machine. The seat reaches the continuous shooting function and is not limited by the shooting space and mode (such as shooting on the stand).

In order to achieve the above purpose, the present invention provides a new continuous firing gun barrel rear seat type automatic weapon circulation shooting mechanism, which comprises a barrel group with an ammunition firing to provide a warhead to accelerate forward, and a barrel to retreat, one having a high The rigid spring (gun spring) and the gun unit of the rifle, the needle group having the function of firing the ammunition, and the reversing spring seat group providing the function of the rear seat force buffer and the re-entry of the gun. 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 rifle unit completes the push and In the spring action, the last bolt 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 lance unit are simultaneously at the same time, and the rear seat of the barrel is repeated. The purpose of automatic continuous shooting of weapons.

When the bolt 221 retreats, the gun 221 is fixed to the gun 221. The cam pin 224 is also rearward. Under the cam groove stroke limit of the breech block 222, the locomotive 221 drives the breech block 222 to rotate and separate from the barrel sleeve 212 (opening the latch). After the barrel 211 is retracted to the extreme position, the barrel is closed. Spring 213 spring force release began to return to home.

The gun 221 and the lance 222 continue to pull the shell backwards. When the shell is separated from the barrel sleeve 212, the shell is lifted by the shell spring, and the shell is thrown away from the gun body 20 to complete the "back shell" and "shell". action.

When the reversing spring seat 241 of the reversing spring seat group 24 retreats and hits the bottom of the gun body 20, the "rear seat" of the automatic cycle is completed, and at this time, the recoil spring 242 starts to rebound and releases energy to push the gun unit 22 and hit. The needle set 23 and the recoil spring set 24 are retracted forward, and the bolt 222 teeth will push the secondary shot forward into the magazine to complete the "push" and "inject" movements of the automatic cycle, and finally the bolt 222 Entering the barrel sleeve 212 to end the end of the barrel 211, the bolt 221 continues to push the breech block 222, is limited by the cam groove stroke of the breech block 222, and the breech block 222 is squeezed and rotated to combine with the barrel sleeve 212 to complete the automatic cycle. The "lock" action.

At this time, the firing pin 231 of the firing pin group 23 naturally protrudes due to the rotation of the urging bolt 222, and is caught by the ejector pin 233 combined with the retracting spring seat 241, and the impact of the secondary munition is sufficient and continuous. When the gun 221 re-enters the impact of the impactor spring 223, the impact force is interrupted (it is easy to cause non-fire), and after successfully firing the secondary ammunition, it begins to enter the "back shell", "shell", "back seat", Automatic weapon shooting action of "re-entry", "pushing" and "injection", "locking" and "striking" Ring, the purpose of automatic continuous shooting.
