Detailed Description

Referring to fig. 1-6, the present invention is directed to a locking mechanism for a pump shotgun, which comprises a wood guard handle assembly 2, a trigger 32 assembly 3, a magazine and a magazine door 4 for blocking the magazine, wherein the above structures are all disposed in a gun body 1 of the pump shotgun and are the structures existing in the prior art. The wood protection handle assembly 2 is in transmission connection with the magazine door 4 and drives the magazine door 4 to close or open the magazine, the trigger 32 assembly 3 further comprises a trigger 32 and a trigger base 33, the trigger 32 assembly 3 further comprises a locking mechanism 31, and the locking mechanism 31 is arranged in the gun body 1 and close to the magazine door 4 or the wood protection handle assembly 2; the locking mechanism 31 does not contact the magazine door 4 or the wood protection handle assembly 2 under normal conditions, and the magazine door 4 is not limited by the locking mechanism 31 when being blocked or opened; when the trigger 32 component 3 fires the bullet by external force, the locking mechanism 31 is abutted against the magazine door 4 or the wood protection handle component 2, and the magazine door 4 is limited and cannot be opened. When the trigger 32 is pulled, the cartridge door 4 is prevented from being opened to cause shell clamping by rigid locking based on the principle of the wedge block 312; when the trigger 32 is released, the wood protection handle assembly 2 can be normally in transmission connection with the magazine door 4 and drive the magazine door 4 to close or open the magazine.

The wood guard handle assembly 2 may adopt the following structure: the wood protection handle component 2 comprises a wood protection 21 handle and a sliding rod 22, the wood protection 21 handle is arranged at the lower part of the gun body 1, one end of the sliding rod 22 is connected with the wood protection 21 handle, and the other end of the sliding rod 22 is connected with the magazine door 4; when external force makes the back-and-forth movement of fender 21 handle, fender 21 handle drives magazine door 4 back-and-forth movement through slide bar 22 in order to shutoff or open the magazine.

The lock mechanism 31 may adopt the following structure: the locking mechanism 31 comprises a swing rod 311, a wedge block 312 and a boss 313, the trigger base 33 is arranged in the gun body 1, the trigger 32 is arranged on the trigger base 33, one end of the trigger 32 extends out of the gun body 1, and the swing rod 311 is hinged with the trigger base 33 and is shifted by the wedge block 312 to swing; a gap 314 is arranged between the boss 313 and the swing rod 311; the wedge block 312 is hinged with the trigger base 33 and is shifted by the trigger 32 to swing, and the boss 313 is arranged between two positions where the wedge block 312 and the swing rod 311 are respectively hinged with the trigger base 33; when the bullet magazine is used, when an external force pulls the trigger 32, the trigger 32 drives the wedge block 312 to swing until one end of the wedge block 312 is inserted into the gap 314, the wedge block 312 drives the swing rod 311 to swing until one end of the swing rod 311 is in an upward swinging state and abuts against the slide rod 22, the slide rod 22 is limited and cannot move to open the magazine, and at the moment, the swing rod 311 is rigidly locked and cannot swing; when the trigger 32 is released by external force, the wedge 312 moves backwards to unlock the lock, and the swing rod 311 restores the swing function and can open the magazine by moving the handle of the fender 21.
