Lock core structure

Abstract

This invention discloses a lock cylinder structure, including a first lock cylinder part, a second lock cylinder part, and a connecting part. The connecting part is partially connected to the first lock cylinder part and the second lock cylinder part to form a weakened lock cylinder. When the lock cylinder structure is pulled out by an external force, it will break at the connection between the first lock cylinder part or the second lock cylinder part and the connecting part. Therefore, it can avoid the problem in the prior art where the entire lock cylinder is completely pulled out, causing the lock assembly to lose its function.

Claims

1. A lock cylinder structure, installed in the lock sleeve of a lock assembly, the lock cylinder structure comprising: First lock core section; Second lock core section; And a connecting part, with the first lock core and the second lock core respectively connected at both ends, so that the connecting part forms a weakened structure.

2. The lock core structure as described in claim 1, wherein, The first lock core, the second lock core, and the connecting part are cylindrical, and the radius of the connecting part is smaller than the radius of the first lock core and the radius of the second lock core.

3. The lock core structure as described in claim 2, wherein, The radius of the connecting part is one-third to two-thirds of the radius of the first locking part or the radius of the second locking part.

4. The lock core structure as described in claim 1, wherein, The first lock cylinder, the second lock cylinder, and the connecting part are integrally formed.

5. The lock core structure as described in claim 1, wherein, The first lock cylinder and the second lock cylinder each include a plurality of radially arranged slots.

6. The lock core structure as described in claim 5, wherein, The connecting part is located between two adjacent slots of the first lock core and the second lock core.

7. The lock cylinder structure as described in claim 5 further includes a key slot that communicates with each of the slots along the axial direction.

8. The lock core structure as described in claim 1, wherein, The structural dimensions of the connecting part are smaller than those of the first lock core and the second lock core.

9. The lock core structure as described in claim 1, wherein, The connecting part is located at or off the axis of the first lock core and the second lock core.

10. The lock core structure as described in claim 1, wherein, The connecting part is semi-cylindrical or block-shaped.
