Description

Technical Field

[0001] The invention relates to the field of locks, and in particular to a cable lock. Background Art

[0002] Cable locks generally use steel cables as flexible parts and cooperate with one-way locking mechanisms for locking. Generally, some parts with holes are locked to prevent them from being unlocked.

[0003] Traditional cable locks can only be opened with one or multiple copies of a key, and cannot be cross-verified when opened. Therefore, it is necessary to design a cable lock that can achieve cross-verification of different identity information. Summary of the invention

[0004] Based on the above problem, an object of the present invention is to provide a cable lock capable of realizing multiple cross-verification.

[0005] In view of the above problems, the following technical solutions are provided: a cable lock comprises a lock shell and a cable connected to the lock shell at one end, the lock shell being provided with a tapered guide groove, a rope threading path passing through the narrow end and the wide end of the tapered guide groove and through the lock shell, the cable passing through the rope threading path and passing through the tooth surface of the extrusion block in the tapered guide groove, one end of the extrusion block being provided with an elastic member to tighten it toward the narrow end of the tapered guide groove, and also comprising an eccentric block which is controlled by a knob to rotate from a first position to a second position to push the extrusion block to move toward the wide end of the tapered guide groove and to loosen the tooth surface of the cable; the eccentric block is provided with a rotation-stopping portion, the lock shell being provided with a lock core and a locking slider which is moved from a third position to a fourth position by rotating the lock core, thereby disengaging from the rotation-stopping portion to unlock the eccentric block and allowing the reset member to accumulate force; the lock shell is also provided with a first interlocking hole which is opened through, an interlocking slider is provided in the lock shell, and a second interlocking hole is provided on the interlocking slider, and when the eccentric block rotates, the interlocking slider is driven to slide to align or stagger the first interlocking hole with the second interlocking hole.

[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 interlocking hole and the second interlocking hole are multiple; when the eccentric block is in the first position, the first interlocking hole and the second interlocking hole are connected to each other.

[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 meshing with the first gear.

[0008] The present invention is further configured such that the lock core is provided with a second gear, and the locking slider is provided with a second rack meshing with the second gear.

[0009] The present invention is further configured such that the lock core is provided with a first torsion spring for driving the lock core to reset.

[0010] The present invention is further configured as follows: the locking slider is provided with a resistance portion; a locking plate is also provided in the lock housing, and after the locking slider is displaced from the third position to the fourth position, the locking plate falls down and resists the resistance portion to limit the locking slider from resetting from the fourth position to the third position; the eccentric block is provided with an unlocking cam, and when the eccentric block is rotated from the first position to the second position, the unlocking cam resists the locking plate to lift it up and disengage from the resistance portion, and the reset member pushes the locking slider to resist the eccentric block to limit its reset to the third position, at which time the locking plate is located above the resistance portion; after the knob controls the eccentric block from the second position to the first position, the anti-rotation portion corresponds to the locking slider, and the locking slider is reset to the third position under the push of the reset member; at the same time, the lock core is reset 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 down by a second torsion spring.

[0012] The present invention is further configured such that an engagement groove is provided at the end of the eccentric block rotating shaft, and the engagement groove engages 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 that are symmetrically arranged.

[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] Beneficial effects of the present invention: 1. When locking, the free end of the cable passes through the rope passage and is clamped by the tooth surface of the extrusion block to prevent it from falling off; when unlocking is required, the key is used to drive the lock core to rotate, so that the lock core drives the locking slider to escape from the anti-rotation part. At this time, the eccentric block is unlocked, and the eccentric block is rotated by turning the knob, so that its eccentric part abuts against the extrusion block and pushes the extrusion block to release the cable; 2. When multiple verifications are required, the padlock is passed through the first interlocking hole and the second interlocking hole in the locked state. In this state, the sliding freedom of the interlocking slider is restricted by the padlock. Therefore, even if the lock core drives the locking slider to unlock the eccentric block, the eccentric block and the interlocking slider cannot rotate the knob to make the eccentric block move from the first position to the second position due to the linkage relationship, thereby achieving the purpose of interlocking and multiple verifications; the elastic member is a cylindrical spring (preferably) or a conical spring or a tension spring or a torsion spring; 3. After the key is inserted into the lock core, the locking slider is driven to move from the third position to the fourth position by twisting the lock core, and then remain in the unlocked state, so that the user can free his hands to turn the knob; after the locking is completed, 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 to make the locking slider automatically bounce into the anti-rotation part to lock the eccentric block. When the locking slider automatically bounces into the anti-rotation part, the lock core is reset together. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0029] refer to Figures 1 to 11 ,like Figures 1 to 11 The cable lock shown in the figure comprises a lock housing 10 and a cable 11 connected to the lock housing 10 at one end. The lock housing 10 is provided with a conical guide groove 101. A cable passage 102 passes through the narrow end and the wide end of the conical guide groove 101 and penetrates the lock housing 10. The cable 11 passes through the cable passage 102 and passes through the tooth surface 121 of the extrusion block 12 in the conical guide groove 101. An elastic member 13 is provided at one end of the extrusion block 12 to tighten it toward the narrow end of the conical guide groove 101. The cable 11 is also controlled by a knob 14 to move the cable from a first position (reference Figure 4 , Figure 7 ) to the second position (reference Fig.10 ) to push the extrusion block 12 to move toward the wide end of the tapered guide groove 101 and to make the tooth surface 121 release the eccentric block 15 of the cable 11; the eccentric block 15 is provided with a stopper 151, and the lock housing 10 is provided with a lock core 16 and the lock core 16 is rotated to realize the rotation from the third position (reference Figure 2 ) to the fourth position (reference Figure 5 ), thereby disengaging from the anti-rotation portion 151 to unlock the eccentric block 15 and allowing the locking slider 18 of the reset member 17 to store force; the lock shell 10 is also provided with a first interlocking hole 103 that is opened through, and an interlocking slider 19 is provided in the lock shell 10, and a second interlocking hole 191 is provided on the interlocking slider 19. When the eccentric block 15 rotates, the interlocking slider 19 is driven to slide to achieve alignment or staggered alignment of the first interlocking hole 103 and the second interlocking hole 191.

[0030] In the above structure, when locked, the free end of the cable 11 passes through the rope passage 102 and is clamped by the tooth surface 121 of the extrusion block 12 to lock and prevent it from falling off; when unlocking is required, the lock core 16 is driven to rotate by the key, so that the lock core 16 drives the locking slide block 18 to disengage from the anti-rotation portion 151, and the eccentric block 15 is unlocked at this time. The eccentric block 15 is rotated by turning the knob 14 so that the eccentric portion 152 abuts against the extrusion block 12 and pushes the extrusion block 12 to release the cable 11; when multiple verifications need to be achieved, the padlock (not shown in the figure) is passed through the first interlocking hole 103 and the second interlocking hole 191 in the locked state. In this state, the sliding freedom of the interlocking slide block 19 is restricted by the padlock (not shown in the figure). Therefore, even if the lock core 16 drives the locking slide block 18 to unlock the eccentric block 15, the eccentric block 15 and the interlocking slide block 19 cannot rotate the knob 14 to move the eccentric block 15 from the first position (reference Figure 4 , Figure 7 ) Go to the second location reference Fig.10 ), so as to achieve the purpose of interlocking and multiple verification; the elastic member 13 is a cylindrical spring (preferably) or a conical spring or a tension spring or a torsion spring; the reset member 17 is a cylindrical spring (preferably) or a conical spring or a tension spring or a torsion spring.

[0031] 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 connected to each other.

[0037] In this embodiment, the lock core 16 is provided with a first torsion spring 162 for driving the lock core 16 to return to its original position.

[0038] In the above structure, the first torsion spring 162 is used to control the automatic resetting of the lock cylinder 16 so that it can be reset to the angle of the key insertion position.

[0039] In this embodiment, the locking slider 18 is provided with a resisting portion 182; the lock housing 10 is further provided with a locking piece 20, and the locking slider 18 is moved from the third position (reference Figure 3 ) to the fourth position (reference Figure 7 ), the locking piece 20 falls down and abuts against the abutment portion 182 to limit the locking slider 18 from the fourth position (reference Figure 7 ) reset to the third position (reference Figure 3 ); The eccentric block 15 is provided with an unlocking cam 154, and the eccentric block 15 is moved from the first position (reference Figure 3 , Figure 7 ) to the second position (reference Fig.10 ) when the unlocking cam 154 abuts against the locking piece 20 to lift it up and disengage the abutting portion 182, and the reset member 17 pushes the locking slider 18 to abut against the eccentric block 15 to limit its reset to the third position (reference Fig.10 ), at this time, the locking piece 20 is located above the abutment portion 182; the knob 14 controls the eccentric block 15 from the second position (reference Fig.10 ) to the first position (reference Figure 4 ) The rear anti-rotation portion 151 corresponds to the locking slider 18, and the locking slider 18 is reset to the third position (reference Figure 4 ); At the same time, the lock core 16 is reset to the position before unlocking under the reverse drive of the locking slider 18.

[0040] In the above structure, when the key is inserted into the lock core 16, the lock slide 18 is driven from the third position (reference Figure 4 ) to the fourth position (reference Figure 7 ) and then remain unlocked, so that the user can free his hands to turn the knob 14; after the locking is completed, the eccentric weight 15 can be moved from the second position (reference Fig.10 ) to the first position (reference Figure 4 ), at this time, the anti-rotation part 151 is reset so that the locking slider 18 automatically bounces into the anti-rotation part 151 to achieve locking of the eccentric block 15, and when the locking slider 18 automatically bounces into the anti-rotation part 151, the lock cylinder 16 is reset together.
