[0028] like Figure 1-4 As shown in the embodiment of this utility model, a composite telescopic cable chain includes a fixed connector 10, a fixed link 20, a movable link 30, and a movable connector 40. The fixed connector 10 is disposed on one side of the fixed link 20, one end of the fixed link 20 is movably disposed on the movable link 30, and one end of the movable link 30 is disposed on the movable connector 40. The movable connector 40 drives the movable link 30 and the fixed link 20 to move. Movable chain plates 31 are provided on both sides of the movable link 30. Two sets of movable chain plates 31 are provided, and the two sets of movable chain plates 31 surround both sides of the movable link 30 to form a movable cavity 32. Movable grooves 33 are provided on the movable chain plates 31, and the fixed link 20 telescopically moves along the movable grooves 33 within the movable cavity 32 of the movable link 30. In this embodiment, the movable joint 40 can flexibly drive the movable link 30 and the fixed link 20 to move, realizing the telescopic movement of the cable chain and meeting the needs of length changes under different working conditions. The two sets of movable chain plates 31 set on both sides of the movable link 30 form a movable cavity 32, and the movable chain plate 31 is designed with a movable slide groove 33, so that the fixed link 20 can move smoothly along the movable slide groove 33 in the movable cavity 32, which enhances the overall structural stability of the cable chain, improves the smoothness of the telescopic process, and reduces jamming. The movable cavity 32 provides a relatively stable space for cables and other components, avoiding them from being interfered with or damaged by external factors during the telescopic process of the cable chain, thus improving its overall durability and reliability. The structure is compact, saves installation space, improves space utilization, and is easy to install and arrange in different equipment and scenarios, further enhancing its application flexibility and adaptability, and making it highly practical.

[0029] like Figure 3As shown, the fixed joint 10 includes a fixed plate 11, a mounting plate 12, and fixed pins 13. The fixed plate 11 and the mounting plate 12 are arranged opposite to each other on both sides of the joint. Two sets of fixed pins 13 are provided, each set being located on one side of the mounting plate 12, with the fixed pins 13 facing the fixed link 20. In this embodiment, by having the fixed plate 11 and the mounting plate 12 arranged opposite to each other on both sides of the joint, a stable support can be formed on both sides of the joint, ensuring that the joint maintains a stable position during the operation of the composite telescopic cable chain, reducing swaying and deviation. The fixed pins 13, located on both sides of the mounting plate 12 and facing the fixed link 20, can effectively and tightly connect the mounting plate 12 and the fixed link 20, enhancing the overall stability of the cable chain structure.

[0030] The fixing plate 11 is provided with fixing holes 112, the edges of which are inwardly curved, and the mounting plate 12 is an L-shaped plate. In this embodiment, the inwardly curved design avoids sharp edges on the fixing holes 112, reduces stress concentration, lowers the risk of cracking of the fixing plate 11 due to excessive stress during use, and improves structural stability. The inward curve also provides a certain buffering effect, protecting the connectors passing through the fixing holes 112 during installation and connection, preventing their surfaces from being scratched. The L-shaped mounting plate 12 increases the flexibility and versatility of installation, allowing for easy adaptation to different structures and various installation scenarios.

[0031] Limiting rings 14 are provided on both sides of the fixed joint 10 near the mounting plate 12, and one end of the limiting ring 14 is engaged with both sides of the fixed link 20. In this embodiment, by engaging one end of the limiting ring 14 with both sides of the fixed link 20, the position of the fixed link 20 can be precisely limited, preventing unnecessary displacement or shaking during operation and ensuring the stability of the overall cable chain structure.

[0032] The fixed link 20 includes a fixed chain block 21, a fixed chain plate 22, and a fixed chain pin 23. Two sets of fixed chain plates 22 are provided, each set positioned on both sides of the fixed chain block 21 to form a fixed cavity 24 within the fixed link. The fixed chain pins 23 are positioned at both ends of the fixed chain block 21, facing the movable chain link 30. In this embodiment, the fixed cavities 24 formed by the two sets of fixed chain plates 22 on both sides of the fixed chain block 21 provide stable protection space for internal components, enhancing the overall structural stability and sealing, and effectively preventing debris from entering and affecting the cable chain operation. The fixed chain pins 23, positioned at both ends of the fixed chain block 21, precisely achieve a reliable connection with the movable chain link 30, ensuring the stability and continuity of the cable chain connection during extension and retraction, allowing the cable chain to perform smooth extension and retraction movements, and improving the overall durability and operating performance of the cable chain.

[0033] Fixed chain grooves 221 are provided at both ends of the fixed chain plate 22. One end of the fixed locking pin 13 cooperates with the fixed chain groove 221 so that the fixed joint 10 is placed in the fixed cavity 24. In this embodiment, by fixing the chain groove 221 and cooperating with one end of the fixed locking pin 13, the fixed joint 10 can be accurately positioned and secured in the fixed cavity 24, ensuring that the components of the cable chain are tightly and stably connected during operation, reducing wear and failure caused by shaking and displacement; reliable connection can effectively transmit power and signals, ensuring the continuous and stable operation of the cable chain under complex working conditions, improving its overall operational reliability and stability, extending the service life of the cable chain, and reducing maintenance costs.

[0034] The fixed chain groove 221 is a built-in funnel shape, and one end of the fixed locking pin 13 is an external funnel shape. In this embodiment, the built-in and external funnel shapes enhance the containment capacity of the fixed chain groove 221, adapt to different flow requirements, facilitate the quick and accurate insertion of the fixed locking pin 13 into the corresponding position, optimize the installation process, and reduce installation difficulty and time costs.

[0035] The movable link 30 also includes a movable chain pin 34 and a movable chain groove 35. The movable chain pin 34 is disposed at one end of the movable chain plate 31, and the movable chain groove 35 is disposed at the other end of the movable chain plate 31 opposite to the movable chain pin 34. In this embodiment, by having the movable chain pin 34 disposed at one end of the movable chain plate 31 and the movable chain groove 35 disposed at the other end, the precise positioning and reasonable layout make the connection between the movable links 30 more stable and flexible during the operation of the cable chain.

[0036] The movable chain groove 35 includes a first movable chain groove 36 and a second movable chain groove 37. The first movable chain groove 36 and the second movable chain groove 37 are respectively provided at both ends of the movable slide groove 33. The second movable chain groove 37 is close to the movable chain pin 34. One end of the fixed chain pin 23 cooperates with the movable chain groove 35. When the fixed chain pin 23 is located in the second movable chain groove 37, the fixed chain link 20 is telescopically disposed within the movable cavity 32. In this embodiment, by placing the first movable chain groove 36 and the second movable chain groove 37 at both ends of the movable slide groove 33, a reasonable layout provides a stable track for chain movement, ensuring the smooth operation of the cable chain. Furthermore, the second movable chain groove 37's proximity to the movable chain pin 34 optimizes structural compactness and facilitates overall space utilization. The cooperation between the fixed chain pin 23 and the movable chain groove 35 allows for flexible implementation of different connection states. When the fixed chain pin 23 is in the second movable chain groove 37, the fixed chain link 20 extends and retracts in the movable cavity 32, giving the cable chain the function of extension and retraction. The length can be flexibly changed according to the actual working conditions, which enhances the adaptability of the cable chain to different working environments and improves the overall performance of the equipment.

[0037] The movable joint 40 includes a movable plate 41 and a movable block 42, which are disposed opposite to each other on both sides of the movable joint 40. The movable plate 41 has a movable positioning hole, and the movable block 42 has a movable mounting hole. One end of the movable chain pin 34 engages with the movable positioning hole. In this embodiment, by displacing the movable plate 41 and the movable block 42 on both sides, their respective functional areas are clearly defined. The movable positioning hole on the movable plate 41 engages with one end of the movable chain pin 34 to accurately position the movable chain pin 34, ensuring the accurate position of the moving part when the cable chain extends or retracts, thus making the cable chain run smoothly. The movable mounting hole on the movable block 42 facilitates the secure connection of the movable joint 40 with other components, enhancing the overall structural integrity.

The movable connector 40 drives the movable link 30 and the fixed link 20 to move. Movable chain plates 31 are provided on both sides of the movable link 30. Two sets of movable chain plates 31 are provided, and the two sets of movable chain plates 31 surround both sides of the movable link 30 to form a movable cavity 32. Movable grooves 33 are provided on the movable chain plates 31, and the fixed link 20 telescopically moves along the movable grooves 33 within the movable cavity 32 of the movable link 30. In this embodiment, the movable joint 40 can flexibly drive the movable link 30 and the fixed link 20 to move, realizing the telescopic movement of the cable chain and meeting the needs of length changes under different working conditions. The two sets of movable chain plates 31 set on both sides of the movable link 30 form a movable cavity 32, and the movable chain plate 31 is designed with a movable slide groove 33, so that the fixed link 20 can move smoothly along the movable slide groove 33 in the movable cavity 32, which enhances the overall structural stability of the cable chain, improves the smoothness of the telescopic process, and reduces jamming. The movable cavity 32 provides a relatively stable space for cables and other components, avoiding them from being interfered with or damaged by external factors during the telescopic process of the cable chain, thus improving its overall durability and reliability. The structure is compact, saves installation space, improves space utilization, and is easy to install and arrange in different equipment and scenarios, further enhancing its application flexibility and adaptability, and making it highly practical.
