Problems solved by technology

[0007] Although the safety level of the angle-adjustable positioning lock cylinder can reach the C-level standard, but there are many parts, the structure is complicated, the production cost is high, and it is not suitable for large-scale production. An application for an angle-adjustable comb-tooth positioning lock cylinder has solved this problem to a large extent, but in order to further reduce the number of parts and reduce manufacturing costs, the applicant has improved again and designed a wheel lock lock cylinder

Embodiment

[0046] Such as Figure 1-20 As shown, the rear-action wheel calibration lock cylinder of this embodiment includes a lock shell 1 and a lock cylinder 2 , the lock cylinder 2 is installed in the lock shell 1 , and a key hole 201 is opened on the end surface of the lock cylinder 2 .

[0047] A ring-shaped hollow skeleton 3 is arranged in the lock case 1, and the skeleton 3 is installed on the lock cylinder 2, and the tail of the skeleton 3 is provided with a key slot 301, and the shape of the key slot 301 can be a non-circular shape such as a square, a triangle, a rhombus, an ellipse, etc. In this embodiment, the shape of the key slot 301 is square. When the key is fully inserted, the front end of the key is inserted into the key slot 301, so that the key can drive the skeleton 3 to rotate.

[0048] The lock cylinder 2 is provided with five password units, and the password unit includes a proof ring 4, an angle positioning device for controlling the rotation angle of the proof ri...

Embodiment 2

[0062] In this embodiment, the afterbody of lock cylinder 2 is provided with tail ridge block 206, and the afterbody of skeleton 3 is provided with slot 306, and fixed alignment ring 14 is arranged in slot 306, and is provided with tail ridge block 206 in fixed alignment ring 14. Corresponding notch 141, when installing, firstly install the fixed alignment ring 14 in the slot 306, and then align the tail spine block 206 with the gap 141, the skeleton 3 can be set on the lock cylinder 2, after installation, the tail spine The block 206 is in the gap 141; the circumference of the fixed alignment ring 14 is provided with a fixed alignment groove 142, and the fixed alignment groove 142 is aligned with the lock cylinder alignment groove 204, so that the two ends of the connecting rod 10 are always subject to the fixed alignment groove 142 and the lock cylinder alignment. Due to the role of the groove 204, twisting does not occur.

[0063] Such as Figure 21 and 22 As shown, the s...

Abstract

The invention discloses a lock liner of a wheel lock. The lock liner is of a cylindrical structure, a key hole is formed in the lock liner, a plurality of fixing seats axially distributed at intervalsare arranged on the outer wall of the lock liner, spring holes communicated with the key hole are formed in the fixing seats, clamp arm slots communicated with the spring holes are formed in the axial side faces of the fixing seats, and dovetail slots are formed in the axial side faces of the fixing seats. The fixing seats arranged on the lock liner are used for mounting special lock springs of the wheel lock more conveniently. Besides, the lock liner is reasonable in structural design, and the structure of a lock cylinder can be simplified.

Description

technical field [0001] The invention belongs to the technical field of locks, and in particular relates to a wheel lock, in particular to a cylinder of the wheel lock. Background technique [0002] The lock cylinder is the main part that controls the opening of the lock, and is the core part that is matched with the key to drive the lock tongue to rotate. According to GAT73-2015 "Mechanical Anti-theft Locks" promulgated by the Ministry of Public Security, the national standards for anti-theft locks are divided into three levels: A, B, and C. The opening time of the first-level lock cylinder anti-technology technology is not less than 5 minutes, and the opening time of the C-level lock cylinder anti-technology technology is not less than 10 minutes. At present, the safety level of the C-level lock cylinder is the highest. [0003] A-level locks are single-row marble locks. Generally, one-word locks, cross locks, and crescent locks are common. Their anti-theft performance is ...
