Abstract

The utility model discloses a lock head structure, which comprises a lock body; two ends inside the lock body are provided with racing lock cores with the same structure. The utility model is characterized in that: the lock core of the racing lock core and a clutching core are suited inside the lock body with the lock core in front and the clutching core at back; wherein, the clutching core is an unlocking main body and a shifting block are respectively fixed at ends of each lock core clutching core. Compared with the existing lock head, the utility model further improves the performance of preventing the technical unlocking and the destructive prying lock by adopting the racing lock core.

Description

A kind of lock head structure

Technical field

The utility model belongs to mechanical lockset, is specifically related to a kind of lock head structure 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 clutch core 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 the relative clutch core idle running of lock core, 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 lock head structure 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 lock head structure comprises lock body, two in the lock body is provided with the idle-run lock pin of same structure, and the lock core of idle-run lock pin and clutch core retainer plate are in lock body, and lock core is preceding, the clutch core after, the clutch core is the main body of unblanking, and lock core vertically has one to two several pellet shot from a slingshot holes of row, places a spring in the hole, a main pellet shot from a slingshot, vertically have secondary bullet groove at lock core perpendicular to main pellet shot from a slingshot place, secondary pellet shot from a slingshot is placed in the inside, and there are several projections secondary pellet shot from a slingshot the inner, have the clutch cotter way at the clutch core corresponding to secondary pellet shot from a slingshot place, built-in on-of pin has lock slots at lock body corresponding to the on-of pin place, is provided with the pellet shot from a slingshot hole in the groove, put into a spring, a pellet shot from a slingshot, the order of connection is: lock body, spring, on-of pin, secondary pellet shot from a slingshot, main pellet shot from a slingshot, the end of clutch core is fixed with shifting block;

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

The utility model lock head structure 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.

The specific embodiment

The utility model lock head structure is seen Fig. 1 to Fig. 5, one lock body 1 is arranged, two in the lock body 1 is provided with the idle-run lock pin of same structure, the end of each lock core clutch core 3 all is fixed with shifting block 2, and lock core 10 and clutch core 3 are enclosed within the lock body 1, and lock core 10 is preceding, clutch core 3 after, clutch core 3 is the main body of unblanking, and lock core 10 vertically has one to two several pellet shot from a slingshot holes of row, places a spring 4 in the hole, a main pellet shot from a slingshot 5, vertically have secondary bullet groove 12 at lock core 10 perpendicular to main pellet shot from a slingshot 5 places, secondary pellet shot from a slingshot 8 is placed in the inside, and there are several projections 11 secondary pellet shot from a slingshot 8 the inners, have the clutch cotter way at clutch core 3 corresponding to secondary pellet shot from a slingshot 8 places, built-in on-of pin 13 has lock slots 14 at lock body 1 corresponding to on-of pin 13 places, is provided with the pellet shot from a slingshot hole in the groove, put into a spring 16, a pellet shot from a slingshot 15, the order of connection is: lock body 1, spring 16, pellet shot from a slingshot 15, on-of pin 13, secondary pellet shot from a slingshot 8, main pellet shot from a slingshot 5.

Fig. 2, shown in Figure 3 is inserted with key 9 in the lock core 10, clutch core 3 separates with lock body 1, is connected as a single entity with lock core 10, and lock is in opening.

See Fig. 4 and Fig. 5, do not have key in the lock core, the clutch core separates with lock core, is connected as a single entity with lock body, and lock is in closure state, and lock core can arbitrarily rotate.
