Embodiment 1

[0026] Figure 1 to Figure 3 The anti-theft lock according to an embodiment of the present invention is schematically shown. As shown in the figure, the device includes a lock housing 1 and a lock core 2.

[0027] Wherein, the lock shell 1 is provided with a lock shell hole 11 and a lock shell groove 12.

[0028] The lock housing groove 12 is provided on the side wall of the lock housing hole 11.

[0029] The lock core 2 is arranged in the lock housing hole 11 and can rotate freely in the lock housing hole 11.

[0030] The side walls of the lock core 2 are respectively provided with a pin slot 21, a lock lever slot 22 and a lock plate slot 23.

[0031] The lock cylinder 2 is generally provided with a plurality of pin slots 21.

[0032] For example, in this embodiment, the side wall of the lock cylinder 2 is provided with three pin slots 21.

[0033] A plurality of pin slots 21 are respectively arranged along the axial direction of the lock cylinder 2 and the outer ends penetrate the loc...

Embodiment 2

[0058] Figure 4 with Figure 5 The anti-theft lock according to another embodiment of the present invention is schematically shown. As shown in the figure, the difference from Embodiment 1 is that a lock sleeve 6 is also included.

[0059] The lock sleeve 6 is provided with a lock sleeve hole 61.

[0060] The lock sleeve 6 is arranged in the lock shell hole 11.

[0061] The lock core 2 is arranged in the lock sleeve hole 61.

[0062] The side wall of the lock sleeve 6 is provided with a through lock pin hole 62.

[0063] A lock pin 7 is provided in the lock pin hole 62.

[0064] When locking, the lock pin 7 enters the lock shell groove 12 to fix the position of the lock sleeve 6 and the lock shell 1, and the lock core 2 can rotate freely in the lock sleeve 6, thereby forming an idling lock.

[0065] In this embodiment, the thickness of the lock pin 7 is slightly larger than the depth of the lock pin hole 62, and the inner end of the lock pin 7 is in contact with the outer surface of the...

Abstract

The invention discloses an anti-theft lock. The anti-theft lock comprises a lock shell and a lock cylinder. A lock shell hole and a lock shell groove are formed in the lock shell. The lock groove is formed in the side wall of the lock shell hole. The lock cylinder is arranged in the lock shell hole and can rotate freely in the lock shell hole. Marble grooves, a lock rod groove and a lock plate groove are formed in the side wall of the lock cylinder. The multiple marble grooves are formed in the lock cylinder. A marble assembly is arranged in each marble groove. Each marble assembly comprises a marble rod and a spring. A lock plate is arranged in the lock plate groove. The lock plate is in contact with the marble rods. Containing grooves are formed in each marble rod. A lock rod is arranged in the lock rod groove. The lock rod is in contact with the lock plate. The lock rod enters or protrudes out of the surface of the lock cylinder under the effect of the lock plate. By the adoption of the anti-theft lock, the key quantity is increased, the technical unlocking can be prevented effectively, and the safety performance is enhanced greatly; and besides, the marbles are designed in a rod shape, the strength is larger, the situation that the lock cylinder is twisted forcedly with a tool and the marble assemblies in the lock are catastrophically destroyed is avoided, and thus the forced unlocking is prevented effectively.

Description

Technical field [0001] The invention relates to a lock, in particular to an anti-theft lock. Background technique [0002] Locks are common anti-theft tools. Pinball locks are widely used because of their simple structure and practicality. The structure of the pin lock is roughly the same, that is, a set of cylindrical pin is installed in the pin hole of the lock cylinder, and the key has a corresponding depth of teeth. The method of unlocking is also roughly the same, that is, move the corresponding pin up and down through the difference in the height of the key teeth, so that the height of each lock cylinder pin is at the interface between the lock shell and the lock cylinder, and then rotate the key to drive the lock cylinder , To achieve the purpose of unlocking. This type of lock can be inserted into various unlocking tools through the gear channel for technical unlocking. At the same time, this structure wastes the effective stroke of the marble, reduces the density of ...
