Description

Gun lock

The utility model relates to a kind of rifle lock, and particularly a kind of bore of inserting is with the rifle lock of bore locking.

At present, for carrying out strict management to gun, adopt lockset with the gun locking of keeping a kind of good way of getting up can yet be regarded as to the armed people of the consideration of safety.Usually adopt chain lock with gun barrel or gun trigger locking now, gun can not normally be used, thereby reach safe-deposit purpose.But because the chain lock lock body exposes, not only influence the attractive in appearance of gun integral body, also make this lock than destructible simultaneously, the safety of influence keeping gun.

The purpose of this utility model is to provide a kind of lock body hidden in bore, and it is attractive in appearance not influence the rifle body, and firmly the rifle of safety is locked simultaneously.

The utility model is to realize like this, by key and lock rifle lock dimerous, it is characterized in that said lock is made up of following each several part: can insert cylindrical circular lock housing in the bore, be installed in the lock core of an end in the lock housing, to be the lock of garden cylindricality stifled for the vee-cut that has that is installed in that the other end can move forward and backward in the lock housing in lock housing, around lock is stifled, be equipped with simultaneously several can slide along the inclined-plane of vee-cut radial expansion can be with the pintle hook lock of lock body swelling in bore, and between lock housing internal cylinder and lock are stifled, be equipped with one and can spur to lock and get lodged in the locking pull bar that moves forward and backward in the lock housing with inserting key rotation in the lock core.During use, the rifle lock can be inserted bore, key is inserted lock core to rotate, at this moment lock is stifled to travel forward along with the rotation of key constantly spurs to lock pull bar, make pintle hook lock along lock the vee-cut inclined-plane on stifled constantly in the last swelling of radial extent, make whole lock body be locked in securely in the bore, make gun can not shoot shooting, reached safe-deposit purpose.

Advantage of the present utility model is that volume is little, in light weight, simple in structure, cost is low, easy to use, simultaneously because employing band vee-cut lock is stifled, pintle hook lock mechanism finishes locking work, thereby avoided rifle being locked knocking-on possibility at the gun barrel other end, make that the rifle lock is more reliable, guaranteed the safety requirements of gun keepings.

Introduce an embodiment in detail below in conjunction with accompanying drawing

In Fig. 1, lock housing (5) adopts general steel pipe, spacing gets out some apertures on the lock housing one end tube wall, and screw in several Luo silks different in size as snap (4), form lock core, simultaneously make the key (1) that is mated, screw dynamics for strengthening key in addition, also the shank of the key is made into the form that to turn back mutually with the key denticle according to spacing between snap and length.At the lock core other end, fixing one by screw (7) can be with the locking Luo cap of sheet key rotation, the Luo cap cooperates with Luo bolt (9), along with the rotation Luo bolt of Luo cap just can move with stifled one of lock and back that the other end and lock stifled (12) are closely connected, at this moment the steel ball (11) that is installed in the lock housing lockhole will be along locking stifled vee-cut (13) at radial expansion, thereby the lock body swelling in bore, is reached safe-deposit purpose.For preventing that further steel ball slippage in vee-cut from also having installed jump ring additional on lock is stifled, in addition for making stifled reset smoothly also of lock lock on the Luo bolt suit back-moving spring (10).

In Fig. 2, the locking steel ball that symmetry is placed is locked in rifle lock (4) in the bore (15) securely.Want rifle to be locked from the gun barrel other end knocking-on, can under the effect of vee-cut, making the rifle lock be locked in the bore more securely.

For the anti-drilling ability of further strengthening the rifle lock also installs an anti-drilling sheet of locking a door (2) that rotates flexibly additional between lock tube (3) and lock housing outside the keyhole of rifle lock, as Fig. 1

Claims (5)

1, a kind of rifle lock is made up of key and lock two parts, it is characterized in that said lock is made up of following components:

A, can insert and be lock housing cylindraceous in the bore,

B, be installed in the lock core of an end in the lock housing,

C, be installed in that the other end can move forward and backward in the lock housing in lock housing to have the cylindrical lock of vee-cut stifled, around lock is stifled, be equipped with simultaneously several can slide along the inclined-plane of vee-cut radial expansion can be with the pintle hook lock of lock body swelling in bore,

D, between lock housing internal cylinder and lock are stifled, be equipped with one and can spur lock and get lodged in the locking pull bar that moves forward and backward in the lock housing with inserting key turns in the lock core.

2, rifle lock as claimed in claim 1 is characterized in that said pintle hook lock is the symmetrical steel ball that is placed in the stifled vee-cut upper lock body through hole of lock.

3, rifle lock as claimed in claim 1 is characterized in that said locking pull bar is the lock core end to be installed can with blocking up to be connected with lock the stifled screw rod that moves forward and backward of lock be formed with the nut of the key turns of inserting in the lock core.

4, rifle lock as claimed in claim 1 is characterized in that said lock core front end has also installed an anti-drilling sheet of locking a door that can rotate flexibly additional between lock tube and lock housing.

5, rifle lock as claimed in claim 1 is characterized in that said key, and is reflexibie between its shank of the key and the key tooth plate.
