Description

Anti-theft lock with double-mortise

Technical field

This utility model belongs to field of lockset, particularly a kind of anti-theft lock with double-mortise.

Background technology

Lock is that people's daily life is requisite, and the species of lock is also varied, has bright lock, built-in lock, coded lock etc., The safety of lock is extremely important, and the bright lock of some using now and built-in lock only have row's snap, and corresponding key only has row's key Tooth, structure is simple, and encryption degree is low, and safety is low, and the encryption degree of coded lock is high, and safety is higher, but expensive, commonly Other difficult to accept.

Content of the invention

The purpose of this utility model is to provide a kind of rational in infrastructure, safe, anti-theft lock with double-mortise of reasonable price.

According to anti-theft lock with double-mortise of the present utility model, including lock body, lock core and key it is characterised in that lock core includes locking Core frame, internal cylinder and outer lock core, alignment pin, internal cylinder is made up of the fuse of core body, the dead bolt on core body top and core body bottom, fixed Location dimples are had, alignment pin one end is plane, the other end is spherical shape, planar ends pass through spring with lock core frame even in the groove of position Connect, the corresponding location dimples in locating slot are inserted at ball end, the circumference of core body lower surface point centered on end face center Carry the sine wave curved surface for continuous convex-concave, outer lock core one end is the continuously concavo-convex sinusoidal curve corresponding with core body lower surface Face, the other end is connected with lock frame with spring by pad, has 1-5 bar snap passage on outer lock core；Key top be provided with The corresponding groove of fuse shape, is provided with the key bit corresponding with snap passage along key side face.

Described outer lock core quantity is 2,4 or 6.

Anti-theft lock with double-mortise of the present utility model, rational in infrastructure, due to internal cylinder and outer lock core separately, increased adding of lock Density, the variable amounts of outer lock core simultaneously, the encryption degree that increased lock more at double, it is considered to the factor of cost and price, can set Put different outer lock core quantity, both ensure that the safety of lock, reduce cost again.

Brief description

Fig. 1 is the structural representation of this utility model lock core.

Fig. 2 is the structural representation of this utility model key.

Specific embodiment

Specific embodiment of the present utility model is described below in conjunction with the accompanying drawings.

As shown in Figure 1 and Figure 2, anti-theft lock with double-mortise of the present utility model, including lock body, lock core and key it is characterised in that Lock core includes lock core frame 1, internal cylinder 4 and outer lock core 10, alignment pin 3, and internal cylinder 4 is by core body 8, the dead bolt 7 on core body 8 top and core The fuse 9 of body 8 bottom forms, and core body 8 periphery has locating slot 5, has location dimples 6 in locating slot 5, and alignment pin 3 one end is Plane, the other end is spherical shape, and planar ends are connected with lock core frame 1 by spring 2, and ball end is inserted right with it in locating slot 5 In the location dimples 6 answered, core body 8 lower surface circumferential band of point centered on end face center is the sine wave curved surface of continuous convex-concave, Outer lock core 10 one end is the continuously concavo-convex sine wave curved surface corresponding with core body 8 lower surface, and the other end passes through pad 12 and spring 13 are connected with lock core frame 1, have 1-5 bar snap passage 11 on outer lock core 10；Key top is provided with relative with fuse 9 shape The groove 14 answered, is provided with the key bit 15 corresponding with snap passage 11 along key side face, as shown in Figure 2.

In order to increase encryption degree, improve safety, outer lock core quantity is 2,4 or 6.

Anti-theft lock with double-mortise of the present utility model, when key is correct, can smooth opening；When only key bit and external lock When core spring tooth correspondence is correct, internal cylinder is motionless, and outer lock core sine wave curved surface is formed with internal cylinder sine wave curved surface and slides, outer lock core Crest slides to internal cylinder crest, and now internal cylinder is motionless, and outer lock core is pressed down against spring, forms outer lock core idle running, lock can not Open；When only key bit is corresponding with internal cylinder fuse correct, outer lock core is motionless, and internal cylinder sine wave curved surface is with outer lock core just String curve face correspondence remains stationary as, and locks nor opens.

This anti-theft lock with double-mortise is rational in infrastructure, and encryption degree is high, safe and reliable, is the bright of low encryption degree in the market Lock, the renewal product of built-in lock.
