Technical Field

[0001] This utility model relates to the field of locks, specifically to a cable lock. Background Technology

[0002] Cable locks typically use steel cables as flexible components, coupled with a one-way locking mechanism for locking. Traditional cable locks can only be opened with one or more duplicate keys, making cross-verification during opening impossible. To address these issues, the applicant filed a cable lock application on March 5, 2025 (application number 2025102574494), comprising a lock housing and a cable connected to one end thereto. The lock housing has a conical guide groove, and a cable passage extends through the narrow and wide ends of the conical guide groove and through the lock housing. The cable passes through the cable passage and passes through the meshing surface of a pressing block within the conical guide groove. One end of the pressing block has an elastic element that compresses it towards the narrow end of the conical guide groove. The lock also includes a... The invention utilizes a knob control to rotate from a first position to a second position, thereby pushing the compression block towards the wide end of the conical guide groove and releasing the eccentric block from the cable. The eccentric block is equipped with an anti-rotation part, and the lock housing is equipped with a lock cylinder and a locking slider that moves from a third position to a fourth position by rotating the lock cylinder, thereby disengaging from the anti-rotation part to unlock the eccentric block and accumulating force on the reset component. The lock housing is also equipped with a first interlocking hole, an interlocking slider inside the lock housing, and a second interlocking hole on the interlocking slider. Although this invention solves the above problems, its structure is relatively complex and assembly is relatively troublesome. Therefore, it is necessary to optimize its structure to ensure a simplified structure while satisfying the co-locking function. Utility Model Content

[0003] Based on the above problems, the purpose of this utility model is to provide a cable lock with a simple structure that can achieve multiple cross-verification.

[0004] To address the above problems, the following technical solution is provided: a cable lock, comprising a lock housing with a lock cylinder, and a cable fixed at one end to the lock housing; the lock housing has a conical guide groove, and the conical guide groove has a pressing block; it also includes a cable passage that passes through the lock housing and is set through the conical guide groove; the cable passes through the cable passage and passes through the meshing surface of the pressing block in the conical guide groove, one end of the pressing block has an elastic element that compresses it towards the narrow end of the conical guide groove, the narrow end of the conical guide groove has an eccentric block that is controlled to rotate by the lock cylinder, thereby pushing the pressing block towards the wide end of the conical guide groove and causing the tooth surface to release the cable, the eccentric block has a common locking gear; the lock housing also has a common locking slider that can slide relative to the lock housing, the common locking slider has a rack that meshes with the common locking gear, the lock housing has a first hole, and the common locking slider has a second hole that is aligned with or offset from the first hole when it slides.

[0005] The present invention is further configured such that, when there is one first hole, there are multiple second holes arranged at intervals along the sliding direction of the co-locking slider; or when there is one second hole, there are multiple first holes arranged at intervals along the sliding direction of the co-locking slider; or both the first hole and the second hole are multiple and arranged at intervals along the sliding direction of the co-locking slider, and the number of the first hole and the second hole is equal to that of each other.

[0006] The present invention is further configured such that when the eccentric block rotates from the first position to the second position, it pushes the extrusion block to move towards the wide end of the tapered guide groove, and at the same time drives the co-locking slider to make the first hole and the second hole offset from each other; when the eccentric block rotates from the second position to the first position, it releases the extrusion block, and the extrusion block moves towards the narrow end of the tapered guide groove under the push of the elastic element, and at the same time drives the co-locking slider to make the first hole and the second hole aligned with each other.

[0007] The present invention is further configured such that the compression block is two blocks, arranged symmetrically or mirror-imagely to each other, and the cable passes between the two compression blocks; the side of the compression block facing the cable passage is provided with a meshing tooth surface for biting the outer surface of the cable when locked.

[0008] The present invention is further configured such that the end of the extrusion block facing the eccentric block is provided with an inclined surface, and the inclined surface is inclined toward the other extrusion block so that the ends of the two extrusion blocks facing the eccentric block form a V shape; when the eccentric block rotates, it abuts and adapts to the inclined surface.

[0009] In the above structure, the two inclined surfaces are V-shaped. When the eccentric block rotates and pushes the extrusion block, the two V-shaped inclined surfaces can be used to help the two extrusion blocks move away from each other.

[0010] The beneficial effects of this utility model are: 1. While the lock cylinder drives the eccentric block to rotate and unlock the pressing block, the common locking gear and the common locking slider mesh with each other to achieve mutual linkage. In the locked state, the pressing block bites the cable, and the first hole and the second hole are aligned with each other, thus hooking the padlock to achieve co-locking. In this state, the common locking slider is locked by the padlock, and the lock cylinder cannot drive the eccentric block to unlock the pressing block. When the padlock is removed, the common locking slider restores its sliding freedom. At this time, the lock cylinder drives the eccentric block and the common locking slider to unlock the pressing block. The cable can be freely pulled out without the biting and fixing of the pressing block, and the first hole and the second hole are offset from each other. 2. Multiple sets of first and second holes can be set according to the needs of co-locking, so that multiple padlocks can be hung; 3. The two inclined surfaces form a V shape. When the eccentric block rotates and pushes the extrusion block, the two V-shaped inclined surfaces can be used to help the two extrusion blocks move away from each other.
