Description

The rifle lock

The utility model discloses a kind of rifle lock, belong to the gun lock technology field.

Be protection gun safety; prevent that the illegal firearms holder from abusing gun, or, need lockset be installed for gun for preventing that legal gun holder from gun use maloperation taking place; gun are had only under normal circumstances could be used, and can not use under improper situation.

The purpose of this utility model provides a kind of rifle lock, can pin gun, has only legal gun holder just can open the rifle lock, normally uses gun.

The designed rifle lock of the utility model is made up of rifle lock body and dud body, the rifle lock body is made up of mechanical lock head, eccentric pipe, coupling bar and eccentric cap, the shell of mechanical lock head connects with eccentric pipe, the lock core of mechanical lock head connects with coupling bar, coupling bar is installed in the eccentric pipe, and eccentric cap is installed in the end of coupling bar, and lock core and coupling bar are same axial line, eccentric cap and eccentric pipe are same axial line, and eccentric cap is setovered with the relative core of axial line of eccentric pipe and the axial line of coupling bar; The profile of dud body is the cartridge case profile, and dud body front end center has centre bore, and the centre bore rear end has the groove hole greater than center-hole diameter, and the rear end of dud body has centre bore, and mechanical lock head has two latched positions.

Have annular groove in the shell endoporus of described mechanical lock head, the lock core band non-return pin-and-hole of mechanical lock head is equipped with spring and non-return pin in the non-return pin-and-hole, after lock core is packed shell into, in the annular groove in the non-return pin insertion shell endoporus.

Block rubber or spring are housed in the centre bore of dud body rear end.

The designed rifle lock of the utility model can pin gun effectively, prevents illegal use of gun or maloperation.It is simple in structure, easy to use, safe and reliable, not fragile that rifle is locked, and can also protect striker.

Fig. 1 is the front view of the structural representation of rifle lock.

Fig. 2 is the front view of another kind of rifle lock construction schematic diagram.

Below in conjunction with drawings and Examples the utility model is elaborated.

Embodiment 1

The structure of the described rifle lock of present embodiment is seen shown in Figure 1.

The rifle lock is made up of rifle lock body and dud body.The rifle lock body is made up of mechanical lock head 1, eccentric pipe 2, coupling bar 3 and eccentric cap 4.Mechanical lock head 1 is made up of shell 5 and lock core 6, on the inner hole wall of shell 5, have pellet shot from a slingshot hole 7, on lock core 6, have pellet shot from a slingshot hole 8 and keyhole 9, pellet shot from a slingshot 10 is contained in the pellet shot from a slingshot hole 8 on the lock core 6, and can enter in the corresponding pellet shot from a slingshot hole 7 on the shell 5, behind key 11 insertion keyholes 9, lock core 6 can rotate in shell 5.In the endoporus of shell 5, also have annular groove 12, on lock core 6, also have non-return pin-and-hole 13, spring 14 and non-return pin 15 are contained in the non-return pin-and-hole 13, and in lock core 6 is packed the endoporus of shell 5 into, non-return pin 15 will insert in the annular groove 12, make lock core 6 can not withdraw from shell 5.Shell 5 front ends and eccentric pipe 2 usefulness pins 16 are linked together.Coupling bar 3 usefulness pins 17 connect with the front end groove of lock core 6.Eccentric cap 4 usefulness screws are installed in the front end of coupling bar 3.Coupling bar 3 is same axial line with lock core 6, and eccentric pipe 2 is same axial line with eccentric cap 4, the relative coupling bar 2 of axial line of eccentric pipe 2 and eccentric cap 4 and the biasing of the axial line of lock core 6.The profile of dud body 18 is shapes of cartridge case, has centre bore 19 at the front end of dud body 18, and groove hole 20 is arranged behind centre bore 19, and the diameter of groove hole 20 has centre bore 21 greater than the diameter of centre bore 19 in the rear end of dud body 18.

In use, dud body 18 is contained in the rifle boring of gun, the eccentric pipe 2 of rifle lock body is inserted in the gun barrel from muzzle, make the front end of eccentric pipe 2 insert the front end centre bore 19 of dud body 18.Key 11 is inserted in the keyhole 9, lock core 6 is rotated 180 °, lock core 6 drives coupling bar 3 and rotates, the eccentric cap 4 that is installed in coupling bar 3 front ends rotates thereupon, makes eccentric cap 4 cylindricals protrude the cylindrical of eccentric pipe 2, is stuck in the annular groove 20 of dud body 18 front ends, rifle lock body and dud body 18 are linked together, the rifle lock body is fixed in the gun barrel of gun, gun are pinned, Fig. 1 represents that rifle is locked in the state when pinning.

If will open the rifle lock, only need to use key 11 with 180 ° of lock core 6 counter-rotatings, the cylindrical of eccentric cap 4 is overlapped with the cylindrical of eccentric pipe 2, the rifle lock body can separate with dud body 18, takes out the rifle lock body.

Owing between lock core 6 and shell 5 non-return pin 15 is housed, so after lock core 6 packed in the shell 5, lock core 6 can not withdraw from from shell 5 again, thereby can prevent from illegally to take out lock core 6 bittings, thereby the security performance of rifle lock is very high.After preventing that legal gun holder from losing key, can not open the situation of rifle lock, can be with rifle lock numbering, the key model of this rifle lock is kept at the firearm management center backs up.

Embodiment 2

The structure (seeing shown in Figure 2) of the described rifle of present embodiment lock is described basic identical with embodiment 1, difference be eccentric pipe 2 with shell 5 between connects without pin 16, but eccentric pipe 2 and shell 5 are connected as a single entity with welding manner, improved the safety that rifle is locked.The another one difference is in the rear end of dud body 18 centre bore 21 block rubber 22 to be housed, and can cushion striker, the protection striker.Using method is described identical with embodiment 1.Fig. 2 represents that rifle is locked in the state when opening.
