Description

The password check lock lever

The utility model relates to a kind of password check lock lever that is exclusively used in the lock rifle.Existing both at home and abroad various rifles lock all is to pin trigger, puts easily to remove and do not damage gun.

The purpose of this utility model provides a kind ofly can pin bore, removes the brand-new rod-type password rifle that the rifle lock will damage gun by force and locks.

The utility model is achieved in that the tapered end outside makes the cartridge case shape, places bore to be caught on by slip hook.Locking bar inserts from gun barrel and is connected with tapered end, axially the moving back and forth of locking bar inside, makes the steel ball of locking bar front portion be evagination or indentation state by lock core, thereby the tapered end that will be enclosed within the locking bar head is stuck or discharges.The locking bar rear portion connects a password locking device, and when password was upset, lock core can not move axially in locking bar inside, and locking bar can not be extracted from gun barrel, and the bore inner lock head can't take out, the bullet of can not packing into, and rifle can't use.If folding removes the rifle lock by force, rifle is promptly destroyed.Easy to use, safe and reliable.

Concrete structure of the present utility model is drawn by following examples and accompanying drawing.

As shown in the figure, locking bar front portion (3) form locking bar with locking bar rear portion (4).Between locking bar front portion (3) and lock core front portion (5) cylinder (12) steel ball (2) is arranged, have on the cylinder (12) and the corresponding arc groove (21) of steel ball (2).Tapered end (1) outward appearance is the cartridge case shape, and there is the arc groove (20) that adapts with steel ball (2) inside.Go up with steel ball (2) corresponding positions in locking bar front portion (3) and to be equipped with the duck eye (19) that internal diameter is slightly less than steel ball (2), partly stretch out, snap in the tapered end groove (20) to catch on tapered end (1) for steel ball (2).Spring (16) is arranged outside lock core front portion (5) cylinder (12), spring (7) is arranged outside locking bar rear portion (4) clamp (18).The clamp at lock core rear portion has gear on (18), has on the clamp of lock core front portion (17) and the corresponding gear of clamp (18).Centring ring (8) places before the coded lock, can position by pin (9) according to the different size gun.Sealing cap (13) is fixed together by pin (14) with lock core rear portion (6).Between locking bar rear portion (4) and sealing cap (13) space is arranged.When lock was the breakdown state, steel ball (2) did not stretch out the anterior duck eye (19) of locking bar in arc groove (21) and duck eye (19), and tapered end (1) can separate with locking bar.Push sealing cap (13) with hand, it is reciprocating vertically in locking bar that sealing cap drives lock core, lock core rear portion (6) drives clamp (18) and rotates, make clamp (18) inconsistent with the gear protuberance of clamp (17), the anterior cylinder of lock core (12) moves forward, and steel ball (2) leaves groove (21), headed into duck eye (19), the part of steel ball (2) is stretched out the groove (20) that snaps in the tapered end (1) from duck eye (19), and locking bar promptly can't be extracted from tapered end (1), is interim locking-in state.Upset password this moment, by pin (11) space between locking bar rear portion (4) and sealing cap (13) disappeared, and external force acts on lock core is moved axially, and rifle is promptly pinned for a long time.

During use, earlier tapered end (1) is put into bore as putting bullet, catch on, in gun barrel, insert locking bar, click lock nut, promptly pin temporarily, then upset password, promptly pin for a long time with slip hook.When using rifle, set four number passwords earlier correctly, click lock nut, locking bar is extracted gently, draw back rifle bolt, tapered end can be jumped out as shell case is automatic, and rifle can use.

Claims (2)

1, a kind of password check lock lever, it is characterized in that forming by lock core rear portion, lock core front portion, locking bar rear portion, sealing cap (13) locking bar front portion (3) (4) (5) (6) centring ring (8) tapered end (1) steel ball (2) coded lock (15), tapered end (1) profile is the cartridge case shape, inner fluted (20).

2, password check lock lever according to claim 1, it is characterized in that, on the cylinder of lock core front portion (5) fluted (21), duck eye (19) is arranged on the locking bar front portion (3), clamp (17) is arranged on the lock core front portion (5), clamp has gear on (17), and clamp (18) is arranged on lock core rear portion (6), has on the clamp (18) and the corresponding gear of clamp (17).
