Abstract

The utility model provides a combination type anti-theft lock. A plurality of lock body through holes used to be connected with a lock cylinder are installed on the side surface of a lock body. A locking pin used for controlling the relative rotation of the lock cylinder and the lock body is arranged between the lock body and the lock cylinder. The combination type anti-theft lock is further provided with a plurality of marbles, a plurality of locking beads, a plurality of compressed springs and a plurality of seal beads. A plurality of lock cylinder through holes matched with the lock body through holes are positioned on one side of the lock cylinder. A plurality of blades, a plurality of blade springs and a plurality of isolation pieces are further installed inside the lock cylinder. According to the combination type anti-theft lock, a double locking mode combined by locking pin locking and marble locking is utilized, a large number of key codes exist and difficulties of technical unlocking and destructive unlocking are improved, and anti-theft performance can be higher and stronger.

Description

A kind of Combined anti-theft lock

Technical field

The utility model relates to antitheft field, relates in particular to a kind of Combined anti-theft lock.

Background technology

Be locked in antitheft field and belong to an indispensable part, lock also is modal anti-theft tool, is irreplaceable important tool during people live.

Traditional lock all adopts the single lock mode of pellet locking, and this just brings the pins amount few, thereby technical unlocking and the destructive defending performance of opening do not cause by force the shortcomings such as theftproof performance is not strong.

Summary of the invention

For above defective, the utility model provides the novel anti-burglar lock of a kind of hinge, pellet combination.

For achieving the above object, the utility model is by the following technical solutions:

A kind of Combined anti-theft lock, comprise lock body, lock core, described lock body side has some lock body through holes for connecting lock core, also be provided with one between described lock body and the lock core and be used for control lock core and the counterrotating stop pin of lock body, described Combined anti-theft lock also is provided with pellet, locking pearl, stage clip, sealing bead.

Further, described lock core one side is provided with the lock core through hole that is complementary with described lock body through hole, also is provided with hinge, leaf spring and spacer in the described lock core.

The beneficial effect that the utility model brings is: the pins amount is many, adopts the double locking mode of lock pin locking and the combination of cylinder lock phasing, greatly increases technical unlocking and destructive difficulty of opening, and theftproof performance is Gao Gengqiang more.

The specific embodiment

Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that protection domain of the present utility model is made more explicit defining.

Shown in Fig. 1 to 6, a kind of Combined anti-theft lock, comprise lock body 1, lock core 3, described lock body 1 side has some lock body through holes 110 for connecting lock core 3, also be provided with one between described lock body 1 and the lock core 3 and be used for control lock core 3 and lock body 1 counterrotating stop pin 6, described Combined anti-theft lock also is provided with some pellets 7, some locking pearls 9, some stage clips 10, some sealing beads 11; Also establish in addition a jump ring 8, structure such as Fig. 6 are used for lock core 3 is fixed in lock body 1.

Be provided with the lock core through hole 310 that is complementary with described lock body through hole 110 in lock core 3 one sides, also be provided with some hinges 4, some leaf springs 2 and some spacers 5 in the described lock core 3, structure as shown in the figure.

When inserting original key, the spoon code of the identical key of concavo-convex correspondence of tooth code of lock core 3 interior hinges 4, pins will automatically be recombinated and be arranged hinge 4 positions, thereby be directed at hinge 4 top concave indentation word orders, this moment, stop pin 6 was drawn close to lock core 3 centers immediately, and consistent with lock core 3 external diameter levels, lock core 3 is free to rotate, and namely this lockout failure is considered as and can opens.The pellet part also is that same principle is opened.

The utility model adopts the double locking mode of stop pin locking and the combination of cylinder lock phasing, and the pins amount is many, greatly increases technical unlocking and destructive difficulty of opening, and theftproof performance is Gao Gengqiang more.

The above; it only is the specific embodiment of the present utility model; but protection domain of the present utility model is not limited to this; any those of ordinary skill in the art are in the disclosed technical scope of the utility model; variation or the replacement that can expect without creative work all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
