Abstract

The utility model discloses a lock, which comprises a lock body. Wherein, the two points in the lock body is provided with racing lock cores with the same structure, and the utility model is characterized in that: each lock core turn sheath top part is provided with a shifting block. The utility model novel tapered end compared to the current tapered end, as adopting the racing lock core, thus the utility model greatly improves the performance that prevent technological unlock and destructively lock picking.

Description

A kind of tapered end

Technical field

The utility model belongs to mechanical lockset, is specifically related to a kind of tapered end that is used for the built-in type mortise door lock.

Background technology

The tapered end of existing built-in type mortise door lock wherein has a kind of twin-lock cored structure, can be from two different directions with key respectively with lock-switch.Two lock cores all are to adopt identical structure, are provided with a shifting block between two lock core ends, and shifting block is realized and the interlock of dead bolt thereby each lock core can drive by an arrangement of clutch.The deficiency of this tapered end is that the lock core that is adopted is not high aspect safety, can not effectively prevent skilled unlocking and destructive picking lock.

Preventing skilled unlocking and destructive picking lock aspect of performance, the lock core that some theftproofs better can dally has appearred at present, this lock core is provided with a turning set between lock core and lock body, be characterized in, can unblank when unblanking with matched key, and when using non-matching key to unblank, can only make lock core relatively rotate cover idle running, this lock core can make external force can't act on lock body and sword iron, thereby has solved powerful unblanking and a destructive difficult problem of unblanking preferably.At present, this class lock core does not also have to find to be applied on the tapered end of built-in type mortise door lock.

Summary of the invention

The purpose of this utility model is at above-mentioned situation, and a kind of tapered end that is used for the built-in type mortise door lock that comprises idle-run lock pin is provided.

The utility model purpose is achieved in that tapered end comprises lock body, and the two in the lock body is provided with the idle-run lock pin of same structure, and the end of each lock core turning set is fixed with shifting block;

Described idle-run lock pin, form by internal cylinder and turning set, columniform internal cylinder is nested in the columnar turning set, arranged side by side vertically on the internal cylinder, have two several main marble holes of row, built-in spring and main pellet shot from a slingshot, one end of spring connects the bottom of main marble hole, the other end connects the afterbody of main pellet shot from a slingshot, the head of main pellet shot from a slingshot extend in the keyhole, main pellet shot from a slingshot is a cylinder, its outside has a V-ring ditch or V-arrangement pit, arrange the V-ring ditch of main pellet shot from a slingshot or the position of V-arrangement pit corresponding to two on the internal cylinder, be provided with auxiliary marble hole, built-in secondary pellet shot from a slingshot, turning set is opened turning set pellet shot from a slingshot hole 1 to several corresponding to the auxiliary marble hole place, built-in turning set pellet shot from a slingshot, lock body has lock hole corresponding to place, turning set pellet shot from a slingshot hole, built-in lock body spring and lock spring, the outer end of lock body spring connects lock body, and the outer end of lock spring is being pressed in the inner, the outer end of turning set pellet shot from a slingshot extend in the lock body lock hole, be connected with the inner of lock spring, the inner of turning set pellet shot from a slingshot is connected with the outer end of the secondary pellet shot from a slingshot of lock core, and the inner of secondary pellet shot from a slingshot is pressed on the outside of main pellet shot from a slingshot.

Although the turning set on the idle-run lock pin engages with shifting block, but can only make lock core relatively rotate cover idle running when unblanking, can not unblank, have only the use matched key owing to the use non-matching key, turning set and lock core are rotated together, drive shifting block and rotate the switch of realizing lock.

The utility model tapered end is compared with existing tapered end owing to adopt idle-run lock pin, make its prevent skilled unlocking and and the performance of destructive picking lock be further enhanced.

Further specify technical solutions of the utility model below in conjunction with accompanying drawing.
