Detailed Implementation

[0022] 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.

[0023] Example 1:

[0024] like Figures 1-9 As shown, this utility model provides a fixing structure for a cable chain, including an upper plate 1 and a lower plate 2. A corrugated pipe 3 is fixedly installed on the upper plate 1 and the lower plate 2. The corrugated pipe includes a first assembly 4 and a second assembly 5. The corrugated pipe 3 has continuously alternating first concave waves 6 and second concave waves 7. Both the upper plate 1 and the lower plate 2 have a first fixing part 8, which has a first ridge 9. The first ridge 9 is inserted and fixed to the first concave wave 6. A fixing clip 10 is provided inside the corrugated pipe 3. The fixing clip 10 has a second ridge 11, which is inserted and fixed to the second concave wave 7. The fixing clip 10 includes a first clamp 12 and a second clamp 13. The first clamp 12 is fixedly connected to the second clamp 13 via a connecting strap 14. The first clamp 12, the second clamp 13, and the connecting strap 14 are integrally formed. The first clamp 12 has a locking hole 15, and the second clamp 13 has a buckle 16, which is engaged and fixed to the locking hole 15. Both the first clamp 12 and the second clamp 13 are provided with clamping grooves 17. A middle plate 18 is fixedly installed between the upper plate 1 and the lower plate 2. The middle plate 18 is provided with a second fixing part 19 and a third fixing part 20. Both the second fixing part 19 and the third fixing part 20 are provided with a third ridge 21.

[0025] Through the above technical solution, this utility model uses the first convex ridge 9 of the upper plate 1 and the lower plate 2 to insert and fix the first concave corrugation 6 of the corrugated pipe 3, so that the corrugated pipe 3 is stably connected to the fixed structure and the displacement of the corrugated pipe 3 is prevented during the movement of the cable chain. The fixing clamp 10 is provided with a second convex ridge 11, which is inserted and fixed with the second corrugation, so that the fixing clamp 10 is fixed inside the corrugated pipe 3. The fixing clamp 10 is provided with a clamping groove 17, which is designed according to different specifications of cables, to fix the cable to both ends of the corrugated pipe 3, reduce friction loss and noise, and extend the cable life.

[0026] Example 2:

[0027] like Figures 1-9As shown, a corrugated pipe 3 is fixedly installed between the upper plate 1 and the lower plate 2 of this utility model. The upper plate 1 and the lower plate 2 have the same structure and cover each other to fix the corrugated pipe 3. The corrugated pipe 3 is composed of a first assembly 4 and a second assembly 5, which facilitates the insertion of cables into the corrugated pipe 3. The two assemblies are connected to form a complete corrugated pipe 3. The corrugated pipe 3 has continuously alternating first concave waves 6 and second concave waves 7. That is, the first concave wave 6 is concave relative to the outer surface of the corrugated pipe 3, and the second concave wave 7 is concave relative to the inner wall of the corrugated pipe 3. This corrugated structure gives the pipe body good bending performance. Both the upper plate 1 and the lower plate 2 are provided with a first fixing part 8. The size of the first fixing part 8 matches the size of the corrugated pipe 3. The first fixing part 8 has an inwardly protruding first ridge 9. The first ridge 9 and the first concave wave 6 of the corrugated pipe 3 are interlocked and fixed. Through this interlocking connection method, a stable connection between the corrugated pipe 3 and the cable chain body (upper plate 1 and lower plate 2) is achieved. A fixing clip 10 is installed inside the corrugated pipe 3, and the fixing clip 10 has a second protruding ridge 11. The second protruding ridge 11 is inserted and fixed to the second concave wave 7 on the inner wall of the corrugated pipe 3, so that the fixing clip 10 can be firmly installed inside the corrugated pipe 3. This internal fixing structure solves the problem of the lack of effective clamping and fixing of cables inside the corrugated pipe 3 in traditional cable chains. During the use of the cable chain, the upper plate 1 and the lower plate 2 are tightly inserted into the first concave wave 6 of the corrugated pipe 3 through the first protruding ridge 9 of the first fixing part 8, ensuring that the corrugated pipe 3 will not fall off the cable chain body. At the same time, the fixing clip 10 is inserted into the second concave wave 7 of the corrugated pipe 3 through the second protruding ridge 11, so that it is firmly fixed inside the corrugated pipe 3. The fixing clip 10 can be designed with corresponding clamping grooves 17 according to different specifications of cables to fix the cables at both ends of the corrugated pipe 3. This fixing method significantly reduces the shaking and friction of the cables during the movement of the cable chain, thereby reducing noise, reducing cable wear, and extending the service life of the cables. The entire fixing structure is simple to assemble and firmly connected, capable of meeting the demands of frequent reciprocating motion of the cable chain. This fixing structure effectively solves the problems of the single fixing method of the corrugated pipe 3 and the lack of effective clamping and fixing of cables within the corrugated pipe 3 in existing technologies, thus improving the overall stability and reliability of the cable chain system.

[0028] Example 3:

[0029] like Figures 1-9As shown, this utility model further optimizes the structure of the fixing clip 10. The fixing clip 10 includes a first clamping member 12 and a second clamping member 13. The first clamping member 12 is fixedly connected to the second clamping member 13 via a connecting strap 14. One end of the connecting strap 14 is fixedly connected to the connecting piece of the first clamping member 12, and the other end is fixedly connected to the slot of the second clamping member 13. This design allows the fixing clip 10 to form an openable and closable clamping structure, facilitating the clamping clip 10 to hold cables. In use, the cable is placed on the first clamping member 12, and then the second clamping member 13 is closed, forming a surrounding clamping of the cable. The connecting strap 14 acts like a pivot, allowing the first clamping member 12 and the second clamping member 13 to open and close. That is, the flexibility of the connecting strap 14 allows the first clamping member 12 and the second clamping member 13 to adjust the opening and closing angle within a certain range, facilitating the installation and clamping of cables. The clamping slots 17 of the first clamping member 12 and the second clamping member 13 are designed as arc-shaped structures that match the shape of the cable, increasing the contact area and improving clamping stability. The outer surface of the fixing clip 10 is provided with an outwardly protruding second ridge 11, which is used to insert and fix with the second concave wave 7 on the inner wall of the corrugated pipe 3. This structural design enables the fixing clip 10 to be firmly installed in the corrugated pipe 3, improves the stability of the fixing clip 10 in holding the cable, and can effectively prevent the cable from shifting or shaking during the movement of the cable chain, thereby improving the stability and reliability of the entire cable chain system.

[0030] Example 4:

[0031] like Figures 1-9 As shown, this utility model further optimizes the manufacturing process of the fixing clip 10. The first clamp 12, the second clamp 13, and the connecting strap 14 are manufactured using an integral molding process to form a single structure. Both the first clamp 12 and the second clamp 13 are provided with clamping grooves 17 for accommodating and holding cables. The connecting strap 14 is located between the two clamps and adopts a thin-walled structure design to ensure sufficient flexibility. The outer surface of the fixing clip 10 is provided with an annular protrusion, forming a second ridge 11, for insertion into the second concave corrugation 7 of the inner wall of the corrugated pipe 3. The integral molding manufacturing process not only simplifies the production process and reduces manufacturing costs, but also improves the overall strength and durability of the fixing clip 10.

[0032] Example 5:

[0033] like Figures 1-9As shown, the fixing clip 10 of this utility model includes a first clamp 12 and a second clamp 13. The first clamp 12 is fixedly connected to the second clamp 13 via a connecting strap 14. In this embodiment, the first clamp 12 is provided with a locking hole 15, and the second clamp 13 is provided with a snap fastener 16, which engages and fixes with the locking hole 15. This design provides a simple and effective connection method, allowing the fixing clip 10 to be easily opened, closed, and locked. The locking hole 15 is located on one side of the first clamp 12 and can be circular, square, or other shapes. The snap fastener 16 is located on the second clamp 13, corresponding to the locking hole 15 on the first clamp 12. The shape of the snap fastener 16 matches the locking hole 15, and it adopts an elastic design for easy insertion and removal. The head of the snap fastener 16 is slightly larger than the locking hole 15, and it can be firmly locked after insertion to prevent accidental disengagement. The base of the snap fastener 16 is designed with a certain degree of elasticity to absorb vibration and impact during use. In use, close the first clamp 12 and the second clamp 13, align the buckle 16 with the locking hole 15, and then press firmly. The buckle 16 will then insert into the locking hole 15 and lock. This snap-fit ​​method is simple to operate and can be completed without tools, making it suitable for scenarios with frequent opening and closing.

[0034] Example 6:

[0035] like Figures 1-9 As shown, both the first clamp 12 and the second clamp 13 of this utility model are provided with clamping grooves 17. These clamping grooves 17 are designed to better fix and protect the cables, reducing cable swaying and wear during the cable chain's movement. In some testing processes, the clamping grooves 17 of the first clamp 12 and the second clamp 13 can also be used to clamp other components, such as the keel used in the cable chain structure. The inner surfaces of both the first clamp 12 and the second clamp 13 have one or more clamping grooves 17. In use, the operator first opens the fixing clamp 10, and then places cables of different specifications into the corresponding diameter clamping grooves 17. After all cables are in place, the fixing clamp 10 is closed and locked, and the cables are firmly fixed in their respective clamping grooves 17. This design not only effectively fixes the cables but also prevents different cables from tangling and interfering with each other.

[0036] Example 7:

[0037] like Figures 7-9As shown, in some implementations, the cable chain structure requires multiple layers of corrugated pipes 3 to increase cable capacity. This invention addresses this by providing a middle plate 18 between the upper plate 1 and the lower plate 2. The middle plate 18 has a second fixing part 19 and a third fixing part 20 on both sides, extending along the length of the cable chain. Both the second fixing part 19 and the third fixing part 20 have multiple spaced third ridges 21, the shape of which matches the structure of the first concave wave 6 of the corrugated pipe 3. During installation, the first concave wave 6 of the corrugated pipe 3 is first aligned with the first ridge 9 of the lower plate 2 and fixed by insertion. Then, the second ridge 11 of the fixing clip 10 is aligned with the second concave wave 7 of the corrugated pipe 3 and inserted for fixation, thus securing the fixing clip 10 inside the corrugated pipe 3. Next, align and insert the third ridge 21 on the second fixing part 19 or the third fixing part 20 of the middle plate 18 with the first concave wave 6 structure of the other part of the corrugated pipe 3. Repeat the above operation according to the stacking of the drag chain structure. Finally, put the upper cover on the middle plate 18 to complete the installation of the multi-layer corrugated pipe 3.
