Description

Technical Field

[0001] This utility model relates to the field of cable transmission technology, specifically a spring reset mechanism for cables. Background Technology

[0002] In vehicle door locks, household appliances, or other structures that require a pull cord to unlock or operate, a return spring inside the lock is often used to reset the steel cable, thus achieving automatic closing. However, in some scenarios, due to limitations in the lock's internal structure, a return spring cannot be installed, causing the steel cable and pull cord to fail to reset promptly. To solve this problem, a spring reset mechanism needs to be added to the middle of the pull cord to provide external reset force, thereby ensuring the reliability and sensitivity of the pull cord's operation.

[0003] Based on this, the present invention designs a spring reset mechanism for cables to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a spring reset mechanism for cables to solve the above-mentioned technical problems.

An auxiliary slider is fixedly connected to the outside of the wire rope located inside the installation cavity. A spring is sleeved on one end of the auxiliary slider along the direction of the wire rope, and the end of the spring away from the auxiliary slider abuts against the cavity wall of the installation cavity between the main shell and the sub-shell.

[0006] Preferably, the main housing has multiple locking holes at one end facing the sub-housing, and the sub-housing has multiple wedge-shaped locking blocks fixedly disposed at the corresponding locking holes at one end facing the main housing, with the connecting ends of the wedge-shaped locking blocks engaging in the corresponding locking holes.

[0007] Preferably, a spherical block is fixedly provided at one end of the wire rope, and a tension strap is fixedly connected to the end of the wire rope away from the spherical block.

[0008] Compared with the prior art, the beneficial effects of this utility model are: the wire rope slides smoothly in the installation cavity, and the auxiliary slider and spring cooperate to achieve automatic reset, effectively solving the problem of the door lock body having no return spring or insufficient force, and improving the reliability and life of the cable reset.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0013] Please see Figure 1-4 The present invention provides a technical solution: a spring reset mechanism for a cable, comprising: a main housing 1 and a secondary housing 2; the main housing 1 and the secondary housing 2 are interlocked with each other, and two symmetrical limiting guide tubes 3 are interlocked between the main housing 1 and the secondary housing 2, and a steel wire rope 4 is threaded between the limiting guide tubes 3, the main housing 1 and the secondary housing 2; An installation cavity is provided at the joint of the main shell 1 and the sub-shell 2. An auxiliary slider 5 is fixedly connected to the outside of the wire rope 4 located in the installation cavity. A spring 6 is sleeved on one end of the auxiliary slider 5 along the direction of the wire rope 4. The end of the spring 6 away from the auxiliary slider 5 abuts against the cavity wall of the installation cavity of the main shell 1 and the sub-shell 2. Through the cooperation of the main housing 1, the secondary housing 2 and the limiting guide tube 3, the wire rope 4 slides smoothly in the installation cavity, and the auxiliary slider 5 cooperates with the spring 6 to achieve automatic reset.

[0014] More preferably, the main housing 1 has a plurality of locking holes 8 at one end facing the sub-housing 2, and the sub-housing 2 has a plurality of wedge-shaped locking blocks 9 fixedly provided at the corresponding locking holes 8 at one end facing the main housing 1, with the connecting end of the wedge-shaped locking block 9 engaging in the corresponding locking hole 8; The locking holes 8 of the main housing 1 and the wedge-shaped locking blocks 9 of the secondary housing 2 engage with each other, simplifying the installation process, eliminating the use of screws and other fasteners, improving assembly efficiency and stability, ensuring the overall strength of the structure, and reducing manufacturing costs.

[0015] A further preferred embodiment has a spherical block fixedly installed at one end of the wire rope 4, and a pull strap 7 fixedly connected to the end of the wire rope 4 away from the spherical block; The steel wire rope 4 is installed by engaging the door lock device with a ball block at one end to provide force transmission; the pull strap 7 at the other end facilitates user operation, and combined with the reset function of the spring 6, the transmission process is smooth, the action is light and reliable, and the overall practicality of the device is enhanced.

[0016] A specific application of this embodiment is as follows: the wire rope 4 passes through the limiting guide tube 3 in sequence, the spherical block is fixed at one end, the other end is connected to the pull strap 7, and the auxiliary slider 5 is fixed on the outer surface of the wire rope 4, the spring 6 is sleeved and one end of the spring 6 is abutted against the mounting cavity wall of the main housing 1, the main housing 1 and the sub-housing 2 are fixed by wedge-shaped locking block 9 and locking hole 8 to form an integral assembly; When the user pulls the pull strap 7, the steel wire rope 4 drives the door lock or actuator to move, and the auxiliary slider 5 and spring 6 are compressed synchronously. When the user releases the pull strap 7, the spring 6 releases its stored energy, pushes the auxiliary slider 5 to drive the steel wire rope 4 to move in the reset direction, so that the door lock returns to the closed state. The rebound force of spring 6 replaces or supplements the return spring 6 inside the door lock body, ensuring that the cable can reliably reset after the pulling action is completed, and preventing the wire rope 4 from becoming loose or stuck.
