Description

Technical Field

[0001] This utility model relates to the field of cable tie technology, specifically a detachable cable tie. Background Technology

[0002] In numerous fields such as electronic equipment, automotive manufacturing, industrial control, and home wiring, the organization and securing of wire harnesses are crucial for ensuring normal equipment operation, improving space utilization, and enhancing safety. To prevent wire harnesses from becoming tangled, worn, or loosened due to vibration, they are typically secured using cable ties.

[0003] Currently, most common plastic cable ties on the market are single-use structures. They are mainly locked by the interaction of serrations on the ties and locking teeth in the buckle. However, in practical applications, they have drawbacks such as poor disassembly and assembly flexibility and difficulty in reuse. Once the cable ties are tied, if it is necessary to loosen or adjust the cable ties, it is often necessary to use tools such as scissors to cut the cable ties, making the cable ties unusable for reuse. Furthermore, fine-tuning the number of cable ties is cumbersome, especially in scenarios where frequent adjustments to the cable ties are required. This single-use characteristic significantly reduces work efficiency. In addition, the locking force of existing cable ties depends entirely on the degree of manual tightening. If the tightening force is insufficient, the cable ties are prone to gradually loosening due to environmental factors such as cable ties vibration and temperature changes, and even the cable ties may slip off. On the other hand, if the tightening force is too great, it may cause squeezing damage to thinner cable ties, which can easily lead to problems of clamping too loosely or too tightly.

[0004] These shortcomings make it difficult for existing cable ties to meet the actual needs of scenarios with high requirements for flexibility, reusability and clamping stability. Therefore, the development of a cable tie that is easy to install and remove, has stable clamping and is highly adaptable has become an urgent need in the industry. Utility Model Content

[0005] The purpose of this invention is to provide a detachable cable tie to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a detachable cable tie, comprising a cable tie, wherein a clamping and positioning mechanism is provided at one end of the lower surface of the cable tie, the clamping and positioning mechanism comprising a first clamping plate, a second clamping plate and an elastic component, the first clamping plate being fixed to the lower end of the cable tie, the second clamping plate being disposed above the first clamping plate, and the elastic component being disposed between the first clamping plate and the second clamping plate.

[0007] Preferably, the elastic component includes a spring sleeve, which is fixed to the side surface of the elastic component. A rotating shaft is rotatably connected inside the spring sleeve. A first rotating plate is fixed to one end of the rotating shaft extending out of the spring sleeve, and a second rotating plate is fixed to the other end of the rotating shaft extending out of the spring sleeve.

[0008] Preferably, a torsion spring is fitted inside the spring sleeve outside the rotating shaft, one end of the torsion spring is fixed to the inner end wall of the spring sleeve, and the other end of the torsion spring is fixed to the inner end face of the second rotating plate.

[0009] Preferably, a connecting arm is fixed to the upper end of both the first and second rotating plates, and the connecting arm is fixed to the side surface of the second clamping plate.

[0010] Preferably, the inner surface of the second clamping plate is provided with a positioning groove, and the inner top wall of the positioning groove is fixed with an anti-wear pad.

[0011] Preferably, the inner top wall of the positioning groove of the second clamping plate is provided with a strap-through opening, and a relief groove is provided inside the positioning groove on one side of the anti-wear pad, and the relief groove is connected to the strap-through opening.

[0012] This utility model provides a detachable cable tie, which has the following advantages compared with the prior art:

[0013] (1) With the continuous rebound force provided by the torsion spring, the first clamping plate and the second clamping plate can be driven to form a stable clamping force, achieving continuous and stable clamping of the wire harness binding part. This effectively avoids the problem of wire harness loosening or wire harness slippage caused by factors such as wire harness vibration and changes in ambient temperature when simply tightening the wire harness manually, greatly improving the durability of wire harness fixation, and is particularly suitable for scenarios with continuous vibration such as automobiles and machinery. At the same time, the clamping plate spacing can be adjusted by twisting the first and second rotating plates, which can adapt to wire harnesses of different diameters or wire harness binding parts of different thicknesses, avoiding the problem of clamping too loose or too tight due to fixed size, and further expanding the scope of application.

[0014] (2) When it is necessary to increase, decrease or fine-tune the number of wire harnesses later, there is no need to disassemble the wire harness. Simply twist the rotating plate again to overcome the torque of the torsion spring and widen the gap between the clamps to make the adjustment. After adjustment, release the rotating plate, and the clamps will be clamped again under the action of the spring force. The operation is convenient and greatly improves the flexibility during use. There is also a strap-through port for the end of the wire harness to pass through the second clamp. This design can play a clear indication role, allowing users to quickly find the end of the wire harness when disassembling, so as to smoothly carry out the untying operation of the binding structure, saving disassembly time and effort.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4 This utility model provides a detachable cable tie, comprising two main parts: the cable tie 1 and a clamping and positioning mechanism 2. The clamping and positioning mechanism 2 consists of a first clamping plate 3, a second clamping plate 4, and an elastic component 5. The first clamping plate 3 is fixed to the lower end of the cable tie 1, and the second clamping plate 4 is arranged parallel above the first clamping plate 3. The two are elastically clamped by the elastic component 5. During the binding operation, one end of the cable tie 1 firstly and cyclically winds and initially fixes the cable bundle. Then, the first rotating plate 7 is rotated, causing the second rotating plate 8 to rotate synchronously via the rotating shaft 10. During this process, the torsion spring 11 is twisted and stores force, widening the clamping opening between the second clamping plate 4 and the first clamping plate 3. After the end of the cable tie is passed through the threading opening 15, the rotating plate is released, and the rebound force of the torsion spring 11 drives the clamping plate to reset, forming a continuous and stable clamping force.

[0022] The key component of the elastic assembly 5 is the spring sleeve 6, which is rotatably connected to the rotating shaft 10. Spring sleeves 6 extend from both ends of the rotating shaft 10 and are fixedly connected to the first rotating plate 7 and the second rotating plate 8. Notably, a torsion spring 11 is fitted inside the spring sleeve 6 outside the rotating shaft 10. One end of this spring is fixed to the inner end wall of the spring sleeve 6, and the other end is connected to the inner end face of the second rotating plate 8, forming a stable elastic reset structure.

[0023] To achieve linkage adjustment of the clamping plates, the upper ends of the first rotating plate 7 and the second rotating plate 8 are fixed to the side surface of the second clamping plate 4 through the connecting arm 9, so that the rotational movement of the rotating plate can be directly converted into the lifting and lowering adjustment of the second clamping plate 4, thereby changing the clamping distance between it and the first clamping plate 3.

[0024] The inner surface of the second clamping plate 4 is provided with a positioning groove 12, and the top wall of the groove is fixed with an anti-abrasion rubber pad 13, which can enhance the friction of the wire harness and prevent damage to the outer sheath of the wire harness during clamping. The wall where the positioning groove is located is provided with a strap-through opening 15, and a clearance groove 14 connected to the strap-through opening 15 is also reserved in the groove to provide space buffer for the end of the wire harness 1 to pass through; when adding or removing wire harnesses later, there is no need to disassemble the wire harness 1, and the clamping plate can be loosened for adjustment. The design of the strap-through opening 15 can also quickly position the end of the wire harness 1, which is convenient for disassembly operations.

[0025] This solution has the following working process: When binding the wire harness, one end of the wire harness strap 1 is cyclically bound to the wire harness. Then, the first rotating plate 7 is twisted along the spring sleeve 6, causing the rotating shaft 10 to rotate inside the spring sleeve 6. At the same time, the first rotating plate 7 and the second rotating plate 8 overcome the torque of the torsion spring 11 during the torsion adjustment process. This can widen the clamping opening between the second clamping plate 4 and the first clamping plate 3. Then, the end of the wire harness strap 1 is passed out of the second clamping plate 4 through the strap opening 15. The wire harness strap 1 first fixes the wire harness by cyclic binding. Then, the rebound force of the torsion spring 11 drives the clamping plate to close the clamping opening, which can form a continuous and stable clamping force on the wire harness binding part. To prevent the cable tie 1 from loosening or the cable harness from slipping, compared to simply manually tightening the cable tie 1, the continuous torque provided by the torsion spring 11 can counteract the loosening caused by factors such as cable harness vibration and changes in ambient temperature, making it especially suitable for scenarios with vibration, such as automobiles and machinery; the clamping plate spacing can be adjusted by twisting the first clamping plate 3 and the second clamping plate 4 (to overcome the torque of the torsion spring to open), which can adapt to cable harnesses of different diameters or cable tie 1 binding parts of different thicknesses, avoiding the problem of clamping too loose or too tight due to fixed size. For scenarios where the number of cable harnesses needs to be increased or decreased later, the clamping plates can be loosened again, adjusted and reset, without disassembling the cable tie, which is highly flexible;

[0026] After the first clamping plate 3 and the second clamping plate 4 have finished clamping the wire harness, the end of the wire harness 1 passes through the threading opening 15 of the second clamping plate 4. Positioning the end of the wire harness 1 that is free from the wrapping restriction in the threading opening 15 can serve as an indicator, making it easier to quickly find the end of the wire harness 1 and perform the untying operation during subsequent disassembly.
