Description

Technical Field

[0001] This utility model relates to the field of cable chain technology, and in particular to a cable link body with an integrated cable insertion notch structure and its cable chain. Background Technology

[0002] In the current industrial development process, small precision power mechanisms, with their high precision and compactness, are shining brightly in many cutting-edge fields such as high-end electronics manufacturing, micro medical devices, and precision optical instruments. Proper cable arrangement is indispensable for the operation of these power mechanisms, making cable carriers a key element in ensuring their stable operation, bearing the responsibility of keeping cables neatly arranged and free from external interference. Traditional cable carriers commonly employ two assembly methods for their link bodies. One method involves a U-shaped link base and a cover plate that can open and close, with the two components assembled as independent units via a pivot connection. The other method involves the cover plate being fixed to both ends of the link base via snap-fit ​​connections. In the past, in ordinary industrial scenarios and equipment where precision and size requirements were not stringent, these traditional cable carriers were generally sufficient for cable management needs.

[0003] However, times have changed, and small, precision power mechanisms have flourished, leaving traditional cable chains inadequate. On one hand, these power mechanisms are tiny, leaving extremely limited installation space for the cable chains, which must be custom-made to fit their small dimensions. On the other hand, high-precision operating standards demand ever-increasing precision from all cable chain components, with millimeter and micrometer-level tolerances becoming the norm. Against this backdrop, whether it's a shaft connection or a snap-fit ​​method, the connection structure between the cover plate and the chain link base becomes significantly more difficult to assemble due to the need to meet ultra-high precision requirements. Even slight assembly errors during operation can lead to defective products, increasing production costs and drastically reducing efficiency. More problematic is that after deployment, frequent minor vibrations and cable pulling can easily overload the precision connection structure, causing loosening, breakage, and other damage, seriously threatening the operation of the power mechanism, leading to frequent equipment failures and a surge in maintenance costs. Therefore, it is necessary to propose an improved technical solution to address these issues. Utility Model Content

[0004] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.

[0005] A chain link body with an integrated cable insertion notch structure includes a chain link body, the chain link body having two side plates, a bottom plate integrally connected between the lower ends of the two side plates, and a baffle integrally formed on the upper end of the two side plates. The two baffles extend between the two side plates, and a cable insertion notch for cable insertion is formed between the two baffles.

[0006] The front of the two side plates has an inner abutment recess, and the rear of the two side plates has an outer abutment recess corresponding to the inner abutment recess. An outwardly extending connecting post is formed on the inner abutment recess, and a connecting hole corresponding to the connecting post is opened on the outer abutment recess.

[0007] Preferably, the two baffles are designed with a central protrusion on one side, so that the cable can be inserted into the notch to form a structure that is narrow in the middle and wide on both sides.

[0008] Preferably, the upper surface of the baffle is set as an inclined surface, so that the upper ends of the two baffles form a structure that guides the inclination along the middle.

[0009] Preferably, a reinforcing section is formed on the side plate at the position between the inner and outer abutting recesses, and both the baffle and the bottom plate extend at the position of the reinforcing section.

[0010] A cable chain includes a chain link body with an integrated cable insertion notch structure as described above. Multiple chain link bodies are provided, and the multiple chain link bodies are sequentially connected by the cooperation of inner and outer abutment recesses. The multiple chain link bodies are sequentially connected by the rotational connection of connecting posts and connecting holes to form a mutually rotating and cooperating connection structure.

[0011] Preferably, a limiting block is formed at the position of the forming base plate of the side plate, and a blocking part adapted to the limiting block is provided at the front end of the side plate, so that the rotation angle of two adjacent chain links is limited by the limiting block and the blocking part.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] By using two baffles to form a cable insertion notch, the cable can be inserted into the link body along the cable insertion notch during wiring. Once inserted, the cable will be blocked inside the link body without any other external force and will not come out along the cable insertion notch. In other words, the cable insertion notch formed between the two baffles allows the cable to be inserted into the link body and will basically not come out automatically from the cable insertion notch.

[0014] Furthermore, this structural design eliminates the need for workers to open the cover plate during wiring; they can simply insert the cable along the cable guide notch into the main body of the chain link. This simple operation greatly improves the efficiency of wiring work.

[0024] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Please see Figure 1-5 In this embodiment of the utility model, a chain link body with an integrated cable insertion notch structure and its drag chain include a chain link body 10. The chain link body 10 has two side plates 20, a bottom plate 30 integrally connected between the lower ends of the two side plates 20, and a baffle 40 integrally formed on the upper ends of the two side plates 20. The two baffles 40 extend between the two side plates 20, and a cable insertion notch 50 for cable insertion is formed between the two baffles 40.

[0026] The front of the two side plates 20 has an inner abutment recess 21, and the rear of the two side plates 20 has an outer abutment recess 22 corresponding to the inner abutment recess 21. An outwardly extending connecting post 23 is formed on the inner abutment recess 21, and a connecting hole 24 corresponding to the connecting post 23 is opened on the outer abutment recess 22.

[0027] Multiple chain link bodies 10 are connected to form a drag chain. The multiple chain link bodies 10 are connected in sequence through the cooperation of the inner abutment recess 21 and the outer abutment recess 22. After the multiple chain link bodies 10 are connected in sequence through the rotational connection of the connecting post 23 and the connecting hole 24, they form a connection structure that rotates and cooperates with each other.

[0028] When assembling the cable chain, multiple chain link bodies 10 are prepared first. Since the two side plates 20 of each chain link body 10 are designed with inner abutment recesses 21 and outer abutment recesses 22, the front inner abutment recesses 21 and the rear outer abutment recesses 22 can precisely match, allowing adjacent chain link bodies 10 to connect sequentially and initially determine their relative positions. Simultaneously, the connecting post 23 extending outward from the inner abutment recess 21 will be inserted into the connecting hole 24 on the outer abutment recess 22. When the cable chain runs with the small precision power mechanism, the chain link bodies 10 rotate flexibly with each other through the rotating connection structure formed by the connecting post 23 and the connecting hole 24. Regarding cable arrangement, the cables pass through the cable insertion notches 50 between the two baffles 40 sequentially. As the cable chain bends and extends, the cables are securely fixed on the predetermined route, preventing interference or entanglement with the power mechanism throughout the process.

[0029] The main body 10 of this structure is integrally formed, and the side plate 20, bottom plate 30 and baffle 40 are integrated together. The main bodies 10 of each link are connected by simple inner abutment recess 21 and outer abutment recess 22, as well as the rotational connection of the connecting hole 24 and the connecting post 23. This greatly reduces the assembly difficulty, makes it easier for workers to operate, significantly improves production efficiency, and reduces the defect rate.

[0030] By using two baffles 40 to form a cable insertion notch 50, the cable can be inserted into the link body 10 along the cable insertion notch 50 during wiring. After the cable is inserted, it will be blocked in the link body 10 without any other external force and will not come out along the cable insertion notch 50. That is, the cable insertion notch 50 formed between the two baffles 40 allows the cable to be inserted into the link body 10 and will basically not come out automatically from the cable insertion notch 50.

[0031] Furthermore, this structural design eliminates the need for workers to open the cover plate during wiring. They can simply insert the cable along the cable guide 50 into the link body 10, making the operation simple and greatly improving the efficiency of wiring.

[0032] Please see Figure 2-5 The two baffles 40 are designed with a central protrusion on one side, which makes the cable insertion notch 50 narrow in the middle and wide on both sides. The upper surface of the baffles 40 is set as an inclined surface, so that the upper ends of the two baffles 40 form an inclined guiding structure along the middle. Through this setting, the cable can be squeezed into the cable insertion notch 50 more quickly, which further improves the wiring efficiency of workers.

[0033] Please see Figure 2-4 A reinforcing section 25 is formed on the side plate 20 at the position between the inner abutting recess 21 and the outer abutting recess 22. The baffle 40 and the bottom plate 30 are both extended at the position of the reinforcing section 25, which improves the structural strength between the baffle 40, the side plate 20 and the bottom plate 30, thereby improving the overall strength of the chain link body 10.

[0034] Please see Figure 2-3 A limiting block 26 is formed at the position of the forming base plate 30 of the side plate 20. A blocking part 27 adapted to the limiting block 26 is provided at the front end of the side plate 20, so that the flipping angle of two adjacent chain links 10 is limited by the limiting block 26 and the blocking part 27.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
