Abstract

The utility model relates to a lock for special use, particularly a lock for firearm. The lock for firearm solves the defects that the lock body of a chain lock used for locking the inner chamber of firearm is exposed outside, and is easy to be sawed, rasped, gripped, detected with poor safety, but not easy to be put into a gun case, etc. The lock for firearm is characterized in that a lock rod is inserted into the track chamber of a gun barrel, the lock anchor tip of the lock rod is clamped into an anchor tip buckled step arranged inside a lock seat hole which is arranged in a cartridge chamber, and then the lock for firearm is locked. The lock body of the lock for firearm is hidden inside the gun barrel, and a gunpoint lock rod cover as big as a coin is exposed outside, so that the lock for firearm can not be damaged by saws, rasps, etc. With favorable safety performance, the utility model can be made into various specifications for various firearms.

Description

Gun bore lock

The present invention is a kind of specific use lock, and particularly firearms are with locking.

Have firearms now with lock, generally adopt the lock of locking trigger, and thorax in the lock firearms then adopts chain lock, the shortcoming of this lock is that lock body exposes after locking, and outside the outstanding body of a gun, is easily made rifle release, poor stability by hacksaw, file and cutting pliers destruction; Go up the gun of this lock in addition and easily realized, and be difficult for putting in the holster by the people.

It is hidden in gun barrel to the objective of the invention is to design a kind of lock body, is exposed to the outer muzzle lid that has only a coin size, does not influence gun and packs in the holster; Be a kind of with hacksaw, file and cutting pliers all can not destroy and the firearms that reach security purpose with lock.

The object of the present invention is achieved like this: internal bore locks for firearms, formed by lock, locking bar and rifle lock key, and it is characterized in that locking bar inserts in the gun barrel rifling, its lock-anchor tip snaps in step of anchor tip button in the lock seat hole of putting in the cartridge chamber and locks gun barrel; Lock is for intending being placed on the little cylinder by this bullet shell of the outer likeness in form of size in the cartridge chamber of lock firearms; Locking bar overcoat locking bar cover back external diameter is for locking the cylinder that firearms rifle internal diameter is complementary with quilt; This cylinder outer end is the locking bar lid, and cover is intended with lock in the inner end; Cylinder is provided with the break adrift groove of placing break adrift; Each break adrift is provided with the break adrift head, lock shaft hole, snap and anchor point; On rifle lock key body, be provided with and the corresponding step of break adrift head; Inclined to one side 0.9 millimeter of keyhole center and locking bar center line; And on locking bar, also be provided with corresponding lock shaft hole; Be provided with the step of anchor tip button endoporus bottom of matching on lock endoporus top and place top spring and top spring cap with the anchor point.

Above-mentioned design scheme is after being placed on lock, locking bar respectively by the rifle and cartridge chamber of lock firearms, the anchor point will hook step of anchor tip button under the effect of snap, only after inserting this rifle lock key, just can make break adrift put middle position and make locking bar can extract rifle, and then lock taken out in cartridge chamber, releasing is locked, as seen safety is fabulous, and nowhere latch fitting is given prominence to outside the body of a gun, has reached the design effect of expection.

Mark among the figure:

1. rifle lock key, 2. locking bar, 3. locking bar cover, 4. left end break adrift, 5. right-hand member break adrift, 6. left break adrift, 7. right break adrift, 8. in break adrift, 9. lock shaft, 10. lock, 11. top spring caps, 12. top springs, 13. endoporus, 14. left end break adrift steps, 15. right-hand member break adrift steps, 16. left break adrift step, 17. right break adrift steps, break adrift step in 18., 19. the break adrift head, 20. lock shaft holes, 21. snaps, 22. the anchor point, 23. step of anchor tip button, 24. endoporus, 25. spring hole, top, 26. keyholes, 27. locking bars lid, 28. the lock shaft hole, 29. break adrift grooves, 30. inner ends.

As shown in the figure: internal bore locks for firearms, formed by lock 10, locking bar 2 and rifle lock key, it is characterized in that lock 10 is for intending being placed on the little cylinder by this bullet shell of the outer likeness in form of size in the cartridge chamber of lock firearms; Locking bar 2 overcoat locking bars cover 3 back external diameters are for locking the cylinder that firearms rifle internal diameter is complementary with quilt; This cylinder outer end is a locking bar lid 27, and cover is intended with lock 10 in inner end 30; Cylinder is provided with the break adrift groove 29 of placing break adrift; Each break adrift is provided with break adrift head 19, lock shaft hole 20, snap 21 and anchor point 22; On rifle lock key body 1, be provided with and break adrift head 19 corresponding steps; Inclined to one side 0.9 millimeter of keyhole 26 center lines and locking bar 2 center lines; And on locking bar 2, also be provided with corresponding lock shaft hole 20; Be provided with the step of anchor tip button 23 that matches with anchor point 22 on lock 10 endoporus 24 tops; Top spring 12 and top spring cap 11 are placed in endoporus 24 bottoms.As shown in the figure: break adrift comprises left end break adrift 4, right-hand member break adrift 5, left break adrift 6, right break adrift 7 and middle break adrift 8; On rifle lock key 1 body, correspondingly be provided with left end break adrift step 14, right-hand member break adrift step 15, left break adrift step 16, right break adrift step 17 and middle break adrift step 18.

Therefore the break adrift number of the embodiment of the invention is corresponding with the break adrift step of rifle lock key, is five formations, to have five functions not at the same level to the rifle lock key like this, more increased safety of the present invention, the present invention can make different specifications, can be widely used in various firearms.
