Abstract
The utility model discloses a gun stock folding structure, which comprises a gun stock body and a gun breech that are connected rotationally, a gun stock shaft is arranged on one side of the gun breech adjacent to the gun stock body, a barrel-shaped gun stock insert is arranged on one side of the gun stock body adjacent to the gun breech, and the gun stock insert is nested on the gun stock shaft; the gun stock folding structure is characterized in that a projecting tenon extends out of one end of the gun stock insert axially, a positioning groove matched with the projecting tenon is formed at one end of the gun breech, and after the projecting tenon is inserted in the positioning groove, a tailstock body and the gun stock body can be fixed mutually. Preferably, a return spring is arranged between the gun stock insert and the gun stock shaft in a crimping manner. Compared with the prior art, the utility model has the advantages that the gun stock folding structure can be folded and expanded conveniently and quickly.
Description
Technical field
The utility model relates to a kind of alert tommy gun of using, and is especially a kind of alert with tommy gun gun stock foldable structure.
Background technology
At present, domestic firearms field gun stock foldable structure mostly is, comprise the gun stock that is rotatably connected and the tailstock body of genus (descending) casing, the adjacent side of tailstock body and gun stock is provided with the gun stock axle, gun stock body front center is provided with a gun stock trip, and the design of tailstock body bottom has locating slot, gun stock wire-wrap tool holder axle rotation like this, be folding, the expansion of gun stock, its location just must cooperate with the locating slot of tailstock body by the gun stock trip finishes.Therefore, gun stock is folding, launch, and particularly rotates gun stock from folding into again after just can only making its locating slot from tailstock body free the location by the gun stock trip earlier when launching, and it is inconvenient so promptly to have an operation, and gun stock launches long defective consuming time.
The utility model content
Technical problem to be solved in the utility model is, overcomes above-mentioned defective and provides a kind of gun stock to launch more convenient, gun stock foldable structure efficiently.
In order to solve the problems of the technologies described above, adopted following technical scheme in the utility model:
A kind of gun stock foldable structure, comprise the gun stock body and the gun breech that are rotatably connected, an adjacent side with the gun stock body is provided with the gun stock axle on the gun breech, its characteristics are, an adjacent side with gun breech is provided with the gun stock inserts of tubular on the gun stock body, be socketed on the gun stock axle to described gun stock inserts coupling, one end direct-axis of described gun stock inserts is to extending a prominent tenon, described gun breech upper end corresponding position is provided with the locating slot with described prominent tenon coupling, after described prominent tenon inserts locating slot gun breech and gun stock body is interfixed.As optimization, go back crimping between described gun stock inserts and the gun stock axle and be provided with back-moving spring.
Adopted tommy gun of the present utility model, during use, gun stock is from folding into expansion, only need directly upwards spur the gun stock body, make the prominent tenon of gun stock inserts termination break away from locating slot on the gun breech, back-moving spring stretches, it is promptly deployable to rotate the gun stock body, must not press trip again, can make faster and more convenient operation.
In sum, so than prior art, the utility model possesses from folding into and launches convenient, advantage efficiently.
