Description

Technical Field

[0001] The utility model relates to the field of cable locks, in particular to a self-locking micro cable lock. Background Art

[0002] Cable locks generally use a steel cable lock as a flexible part, which is locked in conjunction with a one-way locking mechanism. The current one-way locking mechanism has a complex structure. For example, CN203796859U, a multifunctional steel cable lock, has a conical clamping block 6 and a spring 12 structure. Since the structure is not a standard finished product kit, it is time-consuming to assemble each individual component, which makes the assembly time-consuming and labor-intensive. At the same time, although the existing steel cable lock is equipped with a lock core to achieve controllable unlocking, it is impossible to achieve multiple identity authentication locking. Utility Model Content

[0003] In view of the above problems, the utility model aims to provide a self-locking micro cable lock which has a simple structure, is easy to assemble, can effectively reduce production costs and has reliable locking.

[0004] In view of the above problems, the following technical solutions are provided: a self-locking micro cable lock, comprising a lock shell, a cable with one end fixed to the lock shell, the lock shell also being provided with a socket for inserting the non-fixed end of the cable, a one-way locking mechanism located on the path of the socket being provided in the lock shell, the non-fixed end of the cable being inserted into the one-way locking mechanism via the socket, the one-way locking mechanism being a tension head, the tension tube of the tension head facing the insertion end of the socket, the cable being inserted into the tension tube via the socket and being locked and prevented from retreating by the tension head; a lock core and a lock tongue being provided in the lock shell, a control slider being provided in the lock shell, the sliding freedom of the control slider being controlled by the lock tongue, the sliding direction of the control slider being in the same direction as the unlocking direction of the tension tube or the tension head and being adapted to either of them.

[0005] In the above structure, the tension head (also known as a wire guide or a hanging wire lock or a hanging rope fastener) is an existing finished standard part, and patent No. CN202321370953.8 can be selected. It is specially used for fixing ceiling steel wires, and the finished kit can be directly obtained by bulk procurement. Therefore, the whole can be loaded into the lock shell as a finished kit, which greatly improves the convenience of assembly and improves production efficiency, effectively reduces production costs and labor costs, and cooperates with the lock core and the lock tongue to achieve the locking and unlocking of the control slider, so as to indirectly control the locking and unlocking of the cable by the tension head.

[0006] The utility model is further configured such that when the control slider abuts against the tension tube, the tension head and the lock shell are relatively fixed; when the control slider abuts against the tension head, the tension tube and the lock shell are relatively fixed.

[0007] In the above structure, the control slider preferably abuts against the tension tube.

[0008] The utility model is further configured that the control sliding block is provided with a control portion exposed outside the lock housing.

[0009] In the above structure, when the lock core controls the lock tongue to lock the control slider, the control part exposed from the lock shell cannot control the sliding of the control slider; when the lock core controls the lock tongue to unlock the control slider, the control part exposed from the lock shell can be pushed to slide the control slider, so that it pushes the tension tube to unlock the tension head.

[0010] The utility model is further configured that the control part is provided with one or more external lock holes, and when the control slider slides to unlock the cable, the external lock hole follows the sliding of the control slider and sinks into the lock housing.

[0011] In the above structure, the external lock hole is used to install a third-party padlock. When the external lock hole is occupied by the third-party padlock, the external lock hole will prevent the control slider from sliding. Even when the lock core and the lock tongue are unlocked, the control slider can still maintain a locked state, thereby realizing multiple locking verifications.

[0012] The utility model is further configured that the control slider is provided with a reset spring, and after the tension head is unlocked, the reset spring drives the control slider to slide in the opposite direction to restore the tension head to a locked state.

[0013] In the above structure, when the control slider pushes the tension tube to unlock the tension head, the return spring is controlled to be in a compressed and force-storing state.

[0014] The utility model is further configured that the control sliding block is provided with a guide hole located on the opening path of the insertion hole, and the guide hole is arranged concentrically with the center of the tension tube.

[0015] In the above structure, the guide hole is conical, with the tip of the cone facing the tension tube, and is used to guide the cable to be inserted into the tension tube.

[0016] The utility model is further configured that the tension tube sleeve has a guide sleeve that abuts against the control sliding block.

[0017] In the above structure, the guide sleeve is a spring sleeve, which is used to assist in guiding the cable to pass into the tension tube.

[0018] The utility model is further configured that the insertion hole is arranged through the lock shell.

[0019] In the above structure, when the cable is long, the redundant cable can be passed out.

[0020] The utility model is further configured such that the lock tongue is provided with a retreat surface, and when the lock core is in a locked state, the lock tongue is located on a sliding path of a control slider to restrict its sliding, and when the lock core is in an unlocked state, the retreat surface of the lock tongue provides a sliding space for the control slider.

[0021] In the above structure, the lock tongue is a rotating body, and its retreat surface is arranged on its outer edge or outer side wall.

[0022] The utility model is further configured such that when the control slider unlocks the cable by sliding, the retreat surface is invaded by the control slider to restrict the lock core from returning to the locked state.

[0023] In the above structure, it can be ensured that the lock core is always in the unlocked state before the control slider is reset, so as to avoid the situation that the control slider is not reset after the lock core returns to the locked state, causing the tension head to be unable to lock the cable.

[0024] The beneficial effects of the utility model are as follows: the tension head (also known as a wire guide or a hanging wire lock or a hanging rope fastener) is an existing finished standard part, and patent No. CN202321370953.8 can be selected. It is specially used for fixing ceiling steel wires, and the finished kit can be directly obtained by bulk procurement. Therefore, the whole can be loaded into the lock shell as a finished kit, which greatly improves the convenience of assembly and improves production efficiency, effectively reduces production costs and labor costs, and cooperates with the lock core and the lock tongue to realize the locking and unlocking of the control slider, so as to indirectly control the locking and unlocking of the cable by the tension head.
