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 and are locked in conjunction with a one-way locking mechanism. They are generally used to lock parts with holes to prevent them from being unlocked.
[0003] Traditional cable locks can only be opened with one or more duplicate keys, and cannot perform cross-verification during opening. Therefore, it is necessary to design a cable lock that can achieve cross-verification of different identity information. Utility Model Content
[0004] Based on the above problems, the purpose of this utility model is to provide a cable lock that can achieve multiple cross-verification.
[0005] To address the above problems, the following technical solution is provided: A cable lock includes a lock housing and a cable connected to one end thereto. The lock housing has a conical guide groove, a cable passage extending through the narrow and wide ends of the conical guide groove and through the lock housing, and the cable passes through the cable passage and passes over the toothed 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 an eccentric block, controlled by a knob, which rotates from a first position to a second position to push the pressing block towards the wide end of the conical guide groove and release the cable from its toothed surface. The eccentric block has an anti-rotation part. The lock housing has a lock cylinder and a locking slider that, by rotating the lock cylinder, moves from a third position to a fourth position, thereby disengaging from the anti-rotation part and unlocking the eccentric block, and storing the resetting element. The lock housing also has a through-hole first interlocking hole, an interlocking slider inside the lock housing, and a second interlocking hole on the interlocking slider. When the eccentric block rotates, it drives the interlocking slider to slide, aligning or misaligning the first and second interlocking holes.
[0006] The present invention is further configured such that, when there are multiple first interlocking holes, they are spaced apart along the sliding direction of the interlocking slider; when there are multiple second interlocking holes, they are spaced apart along the sliding direction of the interlocking slider; when there is one first interlocking hole, there are multiple second interlocking holes, or when there are multiple first interlocking holes, there is one second interlocking hole, or both the first and second interlocking holes are multiple; when the eccentric block is in the first position, the first interlocking hole and the second interlocking hole are interconnected.
[0007] The present invention is further configured such that the eccentric block is provided with a first gear, and the interlocking slider is provided with a first rack that meshes with the first gear.
[0008] The present invention is further configured such that the lock cylinder is provided with a second gear, and the locking slider is provided with a second rack that meshes with the second gear.
[0009] The present invention is further provided that the lock cylinder is provided with a first torsion spring for driving its reset.
[0010] The present invention is further configured such that the locking slider has an abutment portion; the lock housing also has a locking plate, after the locking slider moves from the third position to the fourth position, the locking plate falls down and abuts against the abutment portion to restrict the locking slider from resetting from the fourth position to the third position; the eccentric block has an unlocking cam, when the eccentric block rotates from the first position to the second position, the unlocking cam abuts against the locking plate, causing it to lift up and disengage from the abutment portion, and causing the reset member to push the locking slider against the eccentric block to restrict it from resetting to the third position, at which time the locking plate is located above the abutment portion; after the knob controls the eccentric block to move from the second position to the first position, the anti-rotation portion corresponds to the locking slider, and the locking slider resets to the third position under the push of the reset member; at the same time, the lock cylinder resets to the position before unlocking under the reverse drive of the locking slider.
[0011] The present invention is further configured such that the locking piece is controlled to fall by a second torsion spring.
[0012] The present invention is further configured such that the end of the eccentric block rotary shaft is provided with a meshing groove, and the meshing groove meshes with the knob to realize power transmission.
[0013] The present invention is further configured such that the extrusion block is one piece or two pieces arranged symmetrically.
[0014] The present invention is further configured such that the second gear is fan-shaped; when the locking slider is in the third position, the second gear and the second rack are separated; when the lock core rotates, the second gear approaches and meshes with the second rack and controls the locking slider to move from the third position to the fourth position.
[0015] The beneficial effects of this utility model are:
[0016] 1. When locked, the free end of the cable passes through the cable passage and is clamped by the toothed surface of the compression block to lock and prevent it from getting off. When unlocking is required, the key drives the lock cylinder to rotate, causing the lock cylinder to drive the locking slider to disengage from the anti-rotation part. At this time, the eccentric block is unlocked. By turning the knob, the eccentric block is rotated, causing its eccentric part to abut against the compression block and push the compression block to release the cable.
[0017] 2. When multiple verifications are required, the padlock is passed through the first interlock hole and the second interlock hole in the locked state. In this state, the sliding freedom of the interlock slider is restricted by the padlock. Therefore, even if the lock cylinder drives the locking slider to unlock the eccentric block, the eccentric block and the interlock slider cannot rotate the knob to make the eccentric block move from the first position to the second position due to the linkage relationship. This achieves the purpose of interlocking and multiple verifications. The elastic element is a cylindrical spring (preferably), a conical spring, a tension spring, or a torsion spring.
[0018] 3. When the key is inserted into the lock cylinder, the locking slider is moved from the third position to the fourth position by turning the lock cylinder and remains in the unlocked state, so that the user can free up his hand to turn the knob. After locking, the eccentric block can be turned from the second position to the first position by turning the knob. At this time, the anti-rotation part is reset and the locking slider automatically springs into the anti-rotation part to lock the eccentric block. When the locking slider automatically springs into the anti-rotation part, the lock cylinder is reset in conjunction with it. Attached Figure Description

Detailed Implementation
[0031] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.
[0032] refer to Figures 1 to 11 ,like Figures 1 to 11 The cable lock shown includes a lock housing 10 and a cable 11 connected to one end thereto. The lock housing 10 has a conical guide groove 101. A cable passage 102 passes through the narrow and wide ends of the conical guide groove 101 and through the lock housing 10. The cable 11 passes through the cable passage 102 and passes through the toothed surface 121 of a pressing block 12 within the conical guide groove 101. One end of the pressing block 12 has an elastic element 13 that compresses it towards the narrow end of the conical guide groove 101. The lock also includes a knob 14 that controls its movement from a first position (see reference). Figure 4 , Figure 7 Move to the second position (reference) Figure 10 The eccentric block 15 pushes the compression block 12 towards the wide end of the conical guide groove 101 and releases the cable 11 from the tooth surface 121; the eccentric block 15 is provided with an anti-rotation part 151, and the lock housing 10 is provided with a lock cylinder 16 and a third position (see reference) achieved by rotating the lock cylinder 16. Figure 2 ) Displaced to the fourth position (reference) Figure 5 This allows the eccentric block 15 to disengage from the anti-rotation part 151, unlocking the eccentric block 15 and causing the locking slider 18, which is charged by the reset member 17, to be released. The lock housing 10 is also provided with a through first interlocking hole 103, and an interlocking slider 19 is provided inside the lock housing 10. The interlocking slider 19 is provided with a second interlocking hole 191. When the eccentric block 15 rotates, it drives the interlocking slider 19 to slide so that the first interlocking hole 103 and the second interlocking hole 191 are aligned or misaligned.
[0033] In the above structure, when locked, the free end of the cable 11 passes through the cable passage 102 and is clamped by the toothed surface 121 of the compression block 12 to lock and prevent it from slipping. When unlocking is required, the key drives the lock cylinder 16 to rotate, causing the lock cylinder 16 to drive the locking slider 18 to disengage from the anti-rotation part 151. At this time, the eccentric block 15 is unlocked. By rotating the knob 14, the eccentric block 15 is rotated, causing its eccentric part 152 to abut against the compression block 12 and push the compression block 12 to release the cable 11. When multiple verifications are required, in the locked state, the padlock (not shown in the figure) is passed through the first interlocking hole 103 and the second interlocking hole 191. In this state, the sliding freedom of the interlocking slider 19 is restricted by the padlock (not shown in the figure). Therefore, even if the lock cylinder 16 drives the locking slider 18 to unlock the eccentric block 15, the eccentric block 15 and the interlocking slider 19 cannot be linked by rotating the knob 14 to move the eccentric block 15 from the first position (reference). Figure 4 , Figure 7 (Go to the second location for reference) Figure 10 This achieves the purpose of interlocking and multiple verification; the elastic element 13 is a cylindrical spring (preferably), a conical spring, a tension spring, or a torsion spring; the reset element 17 is a cylindrical spring (preferably), a conical spring, a tension spring, or a torsion spring.
[0034] In this embodiment, when there are multiple first interlocking holes 103, they are spaced apart along the sliding direction of the interlocking slider 19; when there are multiple second interlocking holes 191, they are spaced apart along the sliding direction of the interlocking slider 19; when there is one first interlocking hole 103, there are multiple second interlocking holes 191, or when there are multiple first interlocking holes 103, there is one second interlocking hole 191, or both the first interlocking hole 103 and the second interlocking hole 191 are multiple; when the eccentric block 15 is in the first position, the first interlocking hole 103 and the second interlocking hole 191 are interconnected.

Figure 10 At this time, the locking piece 20 is located above the contact part 182; the knob 14 controls the eccentric block 15 from the second position (see reference). Figure 10 ) to the first position (reference) Figure 4 The rear stop part 151 corresponds to the locking slider 18, and the locking slider 18 is reset to the third position by the push of the reset member 17 (see reference). Figure 4 Meanwhile, the lock cylinder 16 is reset to its pre-unlock position under the reverse drive of the locking slider 18.
