Problems solved by technology

Since the number of pins is limited by the size of the lock cylinder, it is impossible to have too many pins. Therefore, the pin lock cylinder can be easily opened in a few seconds, which poses a safety hazard.
[0003] The anti-technical opening measures currently used, such as: special-shaped pins, multi-row pins, beads in beads, etc., all have the same defects as above-mentioned, which is also a key factor for the easy technical opening of the existing pin lock cylinder.

Embodiment 1

[0016] Embodiment 1: As shown in Figures 1 and 2, the key blade 1 is composed of a reverse toothed part 2 and a main body anti-torsion part 3. The cross section of the key blade 1 is W-shaped, and the root of the reversed toothed tooth is anti-rotating to the main body. The torsion part 3 is disconnected, and the anti-torsion part 3 of the main body is connected to the side surface of the anti-twist part 2 in the opening direction of the anti-twist part 2 . The upper denture of the reverse denture part 2 is sunken inwards, and the depth is different, such as: deep denture 15, shallow denture 16, the anti-twist part 3 of the main body and the reverse denture part 2 are in the shallow denture 16 The connection at the side, that is, the direction of the opening of the reverse corrugation is towards the joint of the anti-torque part 3 and the reverse corrugation part 2 of the main body. The lock cylinder 7 is located in the lock cylinder shell 6, and the lock cylinder 7 is provide...

Embodiment 2

[0018] Embodiment 2: As shown in Figures 3 and 4, the key blade 1 is composed of an indented reverse toothed part 2 and a main anti-torsion part 3. The cross section of the key blade 1 is Z-shaped, and the root of the reversed toothed It is disconnected from the anti-torsion part 3 of the main body, and the anti-torque part 2 is connected with the anti-torsion part 3 of the main body through the side of the anti-torsion part 3 in the opening direction of the corrugation. The upper denture of the reverse denture part 2 is sunken inwards, and the depth is different, such as: deep denture 15, shallow denture 16, the anti-twist part 3 of the main body and the reverse denture part 2 are in the shallow denture 16 The connection at the side, that is, the direction of the opening of the reverse corrugation is towards the joint of the anti-torque part 3 and the reverse corrugation part 2 of the main body. On the key blade 1, there is another row of common teeth 10 arranged in parallel ...

Abstract

The present invention discloses a cylinder lock plug capable of preventing illegal unlocking. Its key is formed from reverse toothed pattern portion and torsion-resisting portion, and in the keyhole interior a 'U'-shaped ball groove is set, said ball groove can be used for closing ball head and its two sides, the front end of said key hole at least has one high-position ball, said high-position ball can be used for preventing other key or tool from inserting into said 'U'-shaped ball groove. Said invention can be extensively used in the field of door lock, padlock, car lock, bicycle lock and safe lock, etc.

Description

technical field [0001] The present invention relates to a lock cylinder, especially a tumbler lock cylinder technical background [0002] The existing tumbler lock cylinder is composed of a lock cylinder shell, a lock cylinder, a pin, an elastic element and a key. Middle; when the key is inserted into the keyhole, the tooth flower compresses the head of the pin, so that the pin stops at different heights, and the lock cylinder is opened. Just because the head or two sides of the pin are exposed in the keyhole, a tool can be inserted into the keyhole, and the pin head can be easily moved to try to open the lock. Since the number of pins is limited by the size of the lock cylinder, it is impossible to have too many pins. Therefore, the pin lock cylinder can be easily opened in a few seconds, which poses a safety hazard. [0003] The anti-technical opening measures that adopt at present, as: all there is above-mentioned same defect in special-shaped marble, multi-row marble, ...
