Abstract

The utility model relates to a latching structure of firearms, in particular to a short recoil latching structure of a gun. By adopting a simple processing way, the short recoil latching structure ofthe gun reduces the tolerance, improves the interchangeability among the parts, and effectively lowers the cost, moreover, the structure is simple and the action is reliable, The short recoil latchingstructure of the gun leads a sleeve to be directly and tightly wrapped on the gun pipe, causes the gun pipe and the sleeve to slide parallel when in shooting, reduces the loss due to friction and prolongs the service life, and improves the shooting accuracy; and a long inner guide rail improves the shooting stability. A large latching port greatly increases the locking latching area and improvesthe safety by using large-caliber bullets. The design for separating the pipe from the lock leads the width of a whole gun to be equal to the sum of the pipe diameter and the wall thickness of the sleeve, and is beneficial to the miniaturization of firearms. Moreover, one lock with multi-pipe can achieve fast replacement of the caliber.

Description

The firearms closedown structure

Technical field

The utility model relates to the closedown structure of firearms, especially the short recoil closedown structure of pistol.

Background technology

At present, what known firearms closedown mode was common has two kinds, a kind of floating barrel closedown structure as Austrian Glock17 automatic pistol.It fluctuates by gun barrel and blocks sleeve and finish block action.But in the block action of this mode, gun barrel raises up bigger to the wearing and tearing of sleeve, can influence fire accuracy year in and year out; The floating type gib closedown structure of another kind of as Italian Beretta M92 automatic pistol, he is that the locking lug by the gun barrel below fluctuates and blocks sleeve and finish block action.But this complex structure and huge is unfavorable for the miniaturization of firearms.

Summary of the invention

The utility model can not only improve fire accuracy, increases the service life, and also simple in structure, reliable in action, easy to process, help the miniaturization of firearms.

The technical scheme that its technical problem adopted that the utility model solves is: make sleeve directly wrap tightly gun barrel, gun barrel and sleeve are done parallel sliding during shooting, reduce frictional dissipation and increase the service life, and improve fire accuracy; Guide rail in long improves shooting stability.Large tracts of land locking mouth increases lock iron locking area greatly, improves the security of using large caliber ball cartridge; The design that the pipe lock separates makes the width of whole rifle equal the wall thickness that caliber adds upper bush, is beneficial to the miniaturization of firearms.And a lock multitube can be realized the quick replacing of bore.

The beneficial effects of the utility model are: adopt simple processing mode to reduce tolerance, improve the interchangeability between the parts, effectively reduce cost, improve fire accuracy and security.Increase the service life.More spaces have been arranged, for Chinese military project is done little by little contribution again in the firearms configuration design.

Figure 10 is that figure is finished in the firearms assembling

Figure 11 is firearms when to be hit, locking figure

After Figure 12 was the firearms percussion, figure unblanked

Among the figure: 1. sleeve, 2. gun barrel, 3. locking lug, 4. mouth of pipe sticking patch, 5. whole bar, 6. the kicker tailstock of keeping, 7. kicker bar, 8. whole bar, the 9. kicker of keeping of kicker, 10. gib integral body keeps bar, 11. gib location tapered end, 12. gib back stops, 13. kicker assemblies, 14. the locking lug assembly, 15. receivers.

Concrete implementing method

In Fig. 3, mouth of pipe sticking patch (4), kicker (9), kicker tailstock (6) penetrate in the kicker bar (7) successively.

In Fig. 4, compression kicker (9) is fixed on whole bar (8) the reeve kicker bar (7) that keeps of kicker on the kicker bar (7) with kicker tailstock (6) then, unclamps kicker (9).As Fig. 5, kicker assembly (14) has just assembled.

In Fig. 6, gib back stop (12), gib are located the afterbody that tapered end (11) is put into locking lug (3) successively, pin gib location tapered end (11), the more whole bar (10) that keeps of gib is pacified to go in the locking lug (3) from the side.As figure, locking lug assembly (3) is with regard to installation.

In Fig. 7, the front end of gun barrel (2) from sleeve (1) inserted.

In Fig. 8, with locking lug assembly (14) from the below of sleeve (1) is packed gun barrel (2) into.

In Fig. 9, with pack into the below of sleeve (1) of kicker assembly (14), load onto receiver (15) as figure then, the guide groove that at last integral body is kept bar (5) vertically to pass in the locking lug (3) is installed on the receiver (15).As Figure 10, whole rifle assembling is finished.

In Figure 11,, wait to hit as figure.The lug of locking lug (3) snaps in the locking mouth of sleeve (1), and this moment, block action was finished.

In Figure 12, as figure, behind the percussion bullet, sleeve (1) is slided backward by reaction force, because locking will be with the motion backward together of gun barrel (2), locking lug (3).Locking lug this moment (3) is subjected to the whole guiding that keeps bar (5) to begin downward turn the lug of locking lug (3) is separated with the locking mouth of sleeve (1), and unlocking action is finished at this moment.

Claims

1. firearms closedown structure, assemble in proper order by sleeve, gun barrel, locking lug, kicker assembly, gunlock seat, the structure that when the percussion bullet, prolongs uncaging time, it is characterized in that: after gun barrel is packed into from sleeve the place ahead, refill locking lug, therefore the ammunition feed well width is not subjected to the influence of gun barrel width, can reduce the width of whole rifle.

2. structure according to claim 1 is characterized in that: the sleeve stability in use is long guideway preferably, and large tracts of land locking mouth improves security.

3. structure according to claim 1 is characterized in that: gun barrel separates with locking lug, only need change gun barrel during the conversion bore.
