Description

Anti-drilling lock core

Technical Field

The utility model relates to a lock core, in particular to prevent boring lock core.

Background

The Chinese utility model patent with publication number CN 213330452U, published on 1/6/2021, discloses an anti-theft lock cylinder, and the lock cylinder with the structure adopts the combination of an outer spring transverse locking device and an inner spring transverse locking device, thereby improving the anti-theft effect. The spring lock and blade lock in the prior art can be provided with transverse grid locking mechanisms, but the locking mechanisms with transverse grids have certain defects, and an illegal unlocking person can easily draw out the transverse grids after drilling corresponding parts through an electric drill, so that the locking effect of the transverse grids is lost, and the aim of illegal unlocking is fulfilled. The prior art needs to be improved.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects in the prior art, the utility model provides an anti-drilling lock core which can avoid the transverse bar to be drawn out.

The utility model provides a technical scheme that its technical problem adopted is:

the utility model provides an anti-drill lock core, includes lock shell, lock courage and dials cover and horizontal bars locking device, the lock shell has the mounting hole of axial setting, the lock courage is installed in the mounting hole, lock courage axial direction is equipped with the key hole, state horizontal bars locking device including set up in horizontal bars groove on the lock courage, set up on the lock courage and with the horizontal bars groove side pearl hole that communicates mutually, can horizontal bars inslot radial motion's horizontal bars, can gliding side pearl in the side pearl hole, anti-drill lock core still includes a round pin post be equipped with the bayonet socket on the horizontal bars the lock courage corresponds the position of bayonet socket is equipped with the jack, after the assembly, the round pin post run through in the jack with in the bayonet socket.

Further, the bayonet is arranged at the rear half part of the transverse grid.

Furthermore, the two cross bar locking devices are respectively arranged at two sides of the key hole.

Still further, the cross-sectional shape of the pin is circular or rectangular.

The utility model has the advantages that: compared with the prior art, the bayonet is arranged on the transverse grid and can not be drawn out from the lock cylinder by the pin column clamping column, so that the anti-drilling purpose is achieved, and the anti-theft effect is improved.

Drawings

The present invention will be further explained with reference to the accompanying drawings.

FIG. 1 is an exploded view of one embodiment of the present invention;

figure 2 is a cross-sectional view of the structure of figure 1 as assembled.

Detailed Description

Fig. 1 to 2 show an embodiment of the present invention, including lock shell 1, lock courage 2 and dial cover 3 and horizontal bars locking device 4, lock shell 1 has mounting hole 11 that the axial set up, lock courage 2 is installed in mounting hole 11, lock courage 2 axial direction is equipped with key hole 21, horizontal bars locking device 4 including set up in horizontal bars groove 41 on lock courage 2, set up on the lock courage and with the side pearl hole 42 that horizontal bars groove 41 is linked together, can horizontal bars 43 that the radial motion is in horizontal bars groove 41, can gliding side pearl 44 in the side pearl hole 42. The invention of the utility model is that the lock core also comprises a pin 5, a bayonet 431 is arranged on the cross bar 43, and a jack 22 is arranged at the position of the lock core 2 corresponding to the bayonet 431. When the lock cylinder is assembled, the pin 5 penetrates through the insertion hole 22 and the bayonet 431. The shape and size of bayonet 431 is such that it will accommodate the pin while not interfering with the movement of cross-bar 43 in cross-bar slot 41. The lock core of this kind of structure, at the shutting state, the horizontal bars are the card between lock courage and lock shell, round pin post 5 is in the bayonet socket of horizontal bars 43, after the illegal person of unblanking drills open corresponding position through the electric drill, want to take horizontal bars 43 out, nevertheless because the restriction of round pin post 5, can't take horizontal bars 43 out, even the electric drill destroys the part that horizontal bars 43 are close to the key inserting face, because the effect of blockking of round pin post, the horizontal bars that do not destroy stay in the lock courage also can't be taken out, the horizontal bars that stay in the lock core this moment still can block lock courage and lock shell, the illegal person of unblanking can't unblank, played the theftproof effect, the utility model discloses a round pin post structure is applicable in all tool to locks that have horizontal bars locking device, and horizontal bars locking device can be outer bullet formula, also can be in the inner bullet formula, the utility model discloses a horizontal bars locking device of outer bullet formula.

In order to further improve the anti-theft function, the bayonet 431 is provided at the rear half of the horizontal bar 43. The rear portion here refers to the portion remote from the key insertion. Because the bayonet socket is located the lock courage depths, the electric drill is difficult to destroy bayonet socket and round pin post, further improves the electric drill and destroys the degree of difficulty.

In order to further improve the anti-theft performance, two transverse fence locking devices 4 are respectively arranged on two sides of the key hole 21.

Preferably, the cross-sectional shape of the pin 5 is circular or rectangular. Of course, the cross-sectional shape of the pin 5 may be other shapes.

The above embodiments are not intended to limit the protection scope of the present invention, and those skilled in the art will not depart from the present invention, which is intended to be applicable to the field of the present invention.
