Abstract

The utility model relates to an indirect heterodromous anti-drilling safety lock, which is a theftproof anti-drilling lockset. Lock cores are arranged at the anti-drilling board, the theftproof board, the bushing, the driving head in an indirect order; the spigot of the theftproof board and the end head of the bushing are matched and then fixed in the lock body to make the cross-shaped key slot of the driving head and the cross-shaped key slot of the theftproof board in different directions so that the driving head can occlude the cross-shaped key slot of the theftproof, and occlude the locating tab of the driving head. Therefore, the locating tab is not viewable and operable, and illegal technological opening can be prevented. Putting the cross-shaped key slot of the anti-drilling board and the cross-shaped key slot of the theftproof board in the same direction, and locating the locating tab and the pressure spring on the lock body by the anti-drilling can make the anti-drilling board under twisting and drilling; therefore, the anti-drilling goal can be achieved.

Description

The incorgruous insurance anti-drill lock of segmented

Affiliated technical field:

The incorgruous insurance anti-drill lock of segmented is a kind of antitheft anti-drilling lockset.

Background technology:

Most of security doors adopt the cross key slot of single hop theftproof lock on the preceding market, its structure and operation are: adopt the cross key slot of single hop lock core in lock body, be provided with respectively on lock body and the lock core corresponding alignment pin to the alignment pin on lock core location (i.e. locking) and lock body and the lock core perpendicular to cross key slot, when cross key inserts cross key slot to the alignment pin reorientation (unblanking) on lock body and the lock core, because the alignment pin on lock body and the lock core is perpendicular to cross key slot and adopt the cross key slot of single hop lock core, so the alignment pin of this lock core has visuality, when the person that illegally do not unblank adopt the method for revising the key size to increase the size between key and key slot and use just thread stir alignment pin (alignment pin that is this lock core has operability) can be to the alignment pin reorientation (promptly unblanking) on lock body and the lock core, thereby lost the effect of burglary insurance.

Summary of the invention:

In order to overcome the deficiency that existing theftproof lock has visual and operability, the utility model provides a kind of segmented incorgruous insurance anti-drill lock, and this lock not only can block (be alignment pin on the lock core not visible and can not operate) but also can be effectively anti-drilling to the alignment pin on the lock core.

The technical scheme that its technical problem that solves the utility model adopts is: in lock body, anti-drilling board, anti-theft panel, lining, driving head divides four sections assembled in sequence to become lock core, be fixed in the lock body after the not-go-end of the seam of anti-theft panel and lining cooperated, make the direction of cross key slot on the driving head and the cross key slot on the anti-theft panel incorgruous, anti-theft panel is blocked the cross key slot on the driving head, thereby simultaneously the alignment pin on the driving head is blocked so that the alignment pin on the driving head is not visible and play the purpose that prevents illegal skilled unlocking with operating, cross key slot on the anti-drilling board is consistent with cross key slot direction on the anti-theft panel, and anti-drilling board is positioned at by alignment pin and compression spring pressure can turns round to play anti-drilling purpose when making anti-drilling board be subjected to twist-drill power on the lock body, card is filled up the rear portion that is connected to driving head, shell is fixed on the lock body with screw.

The beneficial effects of the utility model are, can prevent illegal skilled unlocking and bore lock, and are simple in structure.

The specific embodiment:

In figure one, anti-drilling board (9), anti-theft panel (8), lining (7) (seam on the anti-theft panel cooperates with not-go-end on the lining), pack into lock body (1) and lining (7) is fixed on (anti-theft panel (8) is fixed simultaneously) in the lock body (1) of driving head (6) order, with cross key slot direction on the driving head (6) and cross key slot direction consistent (being positioned on the lock body) on the anti-theft panel (8) by alignment pin and compression spring pressure, pack on positioning hole corresponding respectively alignment pin and compression spring places lock-out state with driving head (6), the driver blade (5) of packing at the fluting place at driving head (6) rear portion also will block the draw-in groove that pad (4) snaps in driving head (6) rear portion, with two screws (3) shell (2) will be fixed on the lock body (1).

In figure eight, key when unblanking (10) is by the cross key slot on cross key slot insertion lining (7) key (10) the insertion driving head (6) on anti-drilling board (9), the anti-theft panel (8).

Claims

1. theftproof lock, in lock body, anti-drilling board, anti-theft panel, lining, driving head segmentation assembled in sequence becomes lock core, be fixed in the lock body after the not-go-end of the seam of anti-theft panel and lining cooperated and make cross key slot on the driving head and the direction of the cross key slot on the anti-theft panel incorgruous, anti-drilling board is positioned on the lock body by alignment pin and compression spring pressure, and it is the cross key slot on the anti-drilling board is consistent with cross key slot direction on the anti-theft panel, it is characterized in that: the lock core segmentation structure, in lock body, anti-drilling board, anti-theft panel, lining, the driving head segmentation is assembled into lock core.
