Description
Technical Field
[0001] This utility model relates to the field of cable integration technology, specifically a cable tie with a self-locking function. Background Technology
[0002] Cable ties are tools used to secure and organize wires, cables, pipes, and other cables. They are widely used in industries such as electronics, electrical engineering, communications, automotive, aerospace, and construction to keep cables neat and safe. For example, in the engine compartment of a car, cable ties can be used to secure battery cables, sensor cables, and control cables, ensuring the reliability and safety of the wiring.
[0003] Existing cable ties are basically composed of clips and cable ties. The clips have a deformable and resettable arc-shaped tooth block inside. The resettable nature of the arc-shaped tooth block enables self-locking engagement with the cable ties and completes the limiting of the cable ties. However, after long-term use, the reset speed and reset degree of the arc-shaped tooth block will gradually decrease, eventually leading to the inability to properly engage and limit the cable ties, which reduces the reliability of the cable ties to a certain extent. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cable tie with a self-locking function, including a buckle, a strap body fixedly provided on one side of the buckle, the end of the strap body extending away from the buckle extending into the buckle, an arc-shaped toothed block that can deform and reset fixedly provided inside the buckle, one side of the arc-shaped toothed block engaging with one side of the strap body, a limiting block provided on the side of the arc-shaped toothed block away from the strap body, the limiting block slidingly connected to the arc-shaped toothed block, a power component fixedly provided on the side of the limiting block away from the arc-shaped toothed block, the power component extending into the buckle on the side away from the limiting block, the power component slidingly connected to the buckle, a spring fixedly provided at one end of the power component, the end of the spring away from the power component fixedly connected to the inside of the buckle.
[0006] As a preferred technical solution of this utility model, the power component includes a transmission block, one side of which is fixedly connected to the side of the limiting block away from the arc-shaped tooth block, and a movable groove is provided inside the buckle. The side of the transmission block away from the arc-shaped tooth block extends into the movable groove, and the outer surface of the transmission block is slidably connected to the inner surface of the movable groove.

[0010] As a preferred technical solution of this utility model, two blocking blocks are fixedly provided inside the square groove, and one end of the two blocking blocks is slidably connected to one end of the power block.
[0011] Compared with the prior art, the present invention provides a cable tie with a self-locking function, which has the following advantages:
[0012] The operator applies a thrust to the power component, causing it to drive the limiting block away from the arc-shaped toothed block, thus releasing its support. Simultaneously, the power component compresses the spring. The operator then inserts the belt into the buckle. As the belt enters, it causes the arc-shaped toothed block to deform. When the belt is fully inserted or stops moving, the arc-shaped toothed block resets, engaging with the belt and achieving self-locking. The operator then releases the power component and spring. Due to the spring's elasticity, it drives the limiting block through the power component into the arc-shaped toothed block, providing support. This structure supports the arc-shaped toothed block, ensuring effective engagement between the block and the belt, extending its lifespan, guaranteeing its reset speed and degree, and improving the reliability of the cable tie to some extent.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0020] Please see Figures 1-5 In this embodiment: a cable tie with a self-locking function includes a buckle 1, a strap body 2 fixedly provided on one side of the buckle 1, the end of the strap body 2 extending out of the buckle 1 away from the buckle 1, an arc-shaped toothed block 3 that can deform and reset is fixedly provided inside the buckle 1, one side of the arc-shaped toothed block 3 meshes with one side of the strap body 2, a limiting block 4 is provided on the side of the arc-shaped toothed block 3 away from the strap body 2, the limiting block 4 is slidably connected with the arc-shaped toothed block 3, a power component is fixedly provided on the side of the limiting block 4 away from the arc-shaped toothed block 3, the power component extends into the buckle 1 on the side away from the limiting block 4, the power component is slidably connected with the buckle 1, a spring 5 is fixedly provided on one end of the power component, and the end of the spring 5 away from the power component is fixedly connected to the inside of the buckle 1.
[0021] The blocking block 10 is used to prevent the power block 9 from sticking to the inner wall of the square groove 8 under the drive of the spring 5, thus avoiding the situation where it is difficult for the operator to drive the power block 9 to move, and improving the convenience of the structure. The edge of the limiting block 4 is chamfered so that the chamfered limiting block 4 can smoothly enter the arc-shaped tooth block 3. At the same time, the limiting block 4 is driven by the spring 5 to move. Even if the arc-shaped tooth block 3 suffers material fatigue and cannot be reset normally, the limiting block 4 will automatically enter the arc-shaped tooth block 3, further ensuring the self-locking function of the arc-shaped tooth block 3, ensuring that the arc-shaped tooth block 3 can be reset normally, and ensuring the meshing effect between the arc-shaped tooth block 3 and the belt body 2. To a certain extent, it improves the meshing limit between the arc-shaped tooth block 3 and the belt body 2.
[0022] The power assembly includes a transmission block 6, one side of which is fixedly connected to the side of the limiting block 4 away from the arc-shaped toothed block 3. A movable groove 7 is provided inside the buckle 1. The side of the transmission block 6 away from the arc-shaped toothed block 3 extends into the movable groove 7, and the outer surface of the transmission block 6 is slidably connected to the inner surface of the movable groove 7. A square groove 8 communicating with the movable groove 7 is provided on one side of the buckle 1. A power block 9 is provided inside the square groove 8, and the outer surface of the power block 9 is slidably connected to the inner surface of the square groove 8. The side of the transmission block 6 away from the limiting block 4 extends into the power block 9, and the outer surface of the transmission block 6 is fixedly connected to the inner surface of the power block 9. One end of the power block 9 is fixedly connected to one end of a spring 5. The end of the spring 5 away from the power block 9 is fixedly connected to the inner wall of the movable groove 7. One edge of the outer surface of the limiting block 4 is chamfered. Two blocking blocks 10 are fixedly provided inside the square groove 8, and one end of each blocking block 10 is slidably connected to one end of the power block 9.
[0023] The transmission block 6 limits the position of the limiting block 4 through the movable groove 7, preventing the limiting block 4 from shifting at an angle during movement.
[0024] The working principle and usage process of this utility model are as follows: The operator applies a pushing force to the power block 9, causing the power block 9 to drive the limiting block 4 away from the arc-shaped toothed block 3 through the transmission block 6, thus releasing the support for the arc-shaped toothed block 3. At the same time, the power block 9 drives the spring 5 to be in a compressed state. Then, the operator inserts the belt body 2 into the buckle 1. When the belt body 2 enters the buckle 1, the belt body 2 will drive the arc-shaped toothed block 3 to deform. When the belt body 2 is fully inserted into the buckle 1 or the belt body 2 stops moving, the arc-shaped toothed block 3 performs a reset movement, and the arc-shaped toothed block 3 meshes with the belt body 2, completing the self-locking of the belt body 2. Then, the operator releases the drive of the power block 9 and the spring 5. According to the extensibility of the spring 5, the spring 5 drives the transmission block 6 through the power block 9 to move, causing the transmission block 6 to drive the limiting block 4 into the arc-shaped toothed block 3, thus completing the support for the arc-shaped toothed block 3.
