The joints are rotatably connected to the chain link bodies and adjacent chain link bodies. Each chain link body includes two opposing and parallel chain plates. The joints include two opposing and parallel connecting plates. The tops and bottoms of the opposing chain plates and the opposing connecting plates are connected by crossbeams. The chain plates, connecting plates, and upper and lower crossbeams form a cavity. Buffers are provided between the connecting plates and the chain plates and adjacent chain plates. Gaps for bending the cable chain are provided at the bottom of the junctions between the connecting plates and the chain plates and adjacent chain plates.

[0006] Furthermore, both ends of the crossbeam are detachably connected to the chain plate and connecting plate via a connecting structure.

Detailed Implementation

[0031] The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this utility model will be described below with reference to the accompanying drawings.

[0032] This utility model provides a high-speed, quiet bridge-type cable chain. The cable chain includes several chain link bodies and joints at both ends. The joints are rotatably connected to the chain link bodies and adjacent chain link bodies. Each chain link body includes two opposing and parallel chain plates 2. The joints include two opposing and parallel connecting plates 1. The tops and bottoms of the opposing chain plates 2 and the opposing connecting plates 1 are connected by crossbeams 3. The connecting plates 1, chain plates 2, and upper and lower crossbeams 3 form a cavity. Buffers 4 are provided between the connecting plates 1 and chain plates 2, and between adjacent chain plates 2, to reduce noise and vibration during operation. Gap 5 for bending of the cable chain is provided at the bottom of the junction of the connecting plates 1 and chain plates 2, and between adjacent chain plates 2, facilitating the reciprocating motion of the cable chain. This design is suitable for high-frequency reciprocating motion scenarios. For ease of understanding, as follows... Figure 1 The embodiment shown depicts only one link body, but the number of link bodies can be designed to be several according to actual needs.

[0033] As a preferred structure, such as Figure 1 , 2 As shown in Figures 3, 6, and 10, the two ends of the crossbeam 3 are detachably connected to the chain plate 2 and the connecting plate 1 via a connecting structure. The connecting structure includes a sliding groove 6, a locking groove 7, and a connector 8. The sliding groove 6 and locking groove 7 are located at both ends of the crossbeam 3; the sliding groove 6 is located at the bottom of both ends of the crossbeam 3, and the locking groove 7 is located in the middle of the sliding groove 6. The connector 8 is correspondingly located on the inner edge of the chain plate 2 and the connecting plate 1. The two sides of the connector 8 can mate with the sliding groove 6, and the outer end of the connector 8 has a boss that mates with the locking groove 7. During assembly, the connectors 8 on the inner sides of the upper and lower ends of the chain plate 2 and the connecting plate 1 can be slid into the sliding groove 6 of the crossbeam 3, and the boss at the end of the connector 8 can be slid into the locking groove 7, thus connecting and fixing the crossbeam 3 to the chain plate 2 and the connecting plate 1. Using this assembled structure, cables, oil pipes, air pipes, water pipes, etc., can be installed or repaired by removing the crossbeam, making the operation convenient and quick.

[0034] In specific embodiments of this utility model, such as Figure 1 , 4As shown, the chain plate 2 and the connecting plate 1, as well as the upper and lower parts of two adjacent chain plates 2, are connected by a snap-fit ​​structure, making assembly convenient and quick. The buffer 4 is located in the middle of the chain plate 2 and the connecting plate 1. The buffer 4 is a spring sheet, with cylindrical limiting posts 11 at both ends. The middle edges of the chain plate 2 and the connecting plate 1 are provided with limiting holes 9 that cooperate with the limiting posts 11. The edges of the limiting holes 9 have notches for the spring sheet to pass through. The inner sides of the upper and lower edges of the notches are provided with limiting tongues 18. The middle of the limiting posts 11 is provided with limiting grooves 14 that cooperate with the limiting tongues 18. Both sides of the notches of the chain plate 2 and the connecting plate 1 are arc-shaped grooves 10. After the spring sheet is connected, the arc-shaped grooves 10 on both sides of the chain plate 2 and the connecting plate 1 can be closed to form a circular through hole, which provides space for the spring sheet to bend up and down. The limiting grooves on the limiting posts at both ends of the spring piece cooperate with the limiting protrusions in the limiting holes, allowing the spring piece to bend with the bending of the drag chain. The bent spring piece can bend up and down within the circular hole surrounded by the arc groove, which can reduce friction and vibration between the chain plate and the connecting plate, and between adjacent chain plates, thus achieving the purpose of low-noise operation.

[0035] In specific design, such as Figure 5 , 6 As shown in Figures 7, 8, 9, and 10, the snap-fit ​​structure includes a positioning groove 12 and a corresponding positioning block 13. The positioning groove 12 is located on the inner edge of the chain plate 2 and the connecting plate 1, while the positioning block 13 protrudes from the outer edge of the connecting plate 1 and the chain plate 2. The inner protrusion at the end of the positioning block 13 can be placed within the positioning groove 12, and the inner wall of the positioning groove 12 is an arc-shaped surface for the protrusion to slide back and forth. The connecting plate 1 has positioning blocks 13 and positioning grooves 12 staggered on both sides and at its upper and lower ends. When the cable chain is long and has a large number of chain links, the positioning blocks on the upper part of multiple chain plates and connecting plates are sequentially snapped into the positioning groove in one direction, and the positioning blocks on the lower part are sequentially snapped into the positioning groove in the opposite direction. This structure allows multiple chain plates to interlock sequentially, and the chain plates at both ends to interlock with the connecting plate. The positioning groove provides sliding space for the positioning blocks, thereby meeting the bending requirements of the cable chain.

[0036] In specific embodiments of this utility model, such as Figure 1 , 11 As shown, one or more partitions 15 are provided between the upper and lower corresponding crossbeams 3. The partitions 15 are arranged parallel to the chain plate 2 and the connecting plate, and the upper and lower ends of the partitions 15 are detachably connected to the crossbeams 3. The upper and lower edges of the partitions 15 are provided with protruding C-shaped buckles 16, which can slide and engage with the edges of the crossbeams 3. This structure facilitates the adjustment of the position of the partitions on the crossbeams, and multiple partitions can be installed side-by-side as needed to easily separate cables and various pipelines.

[0037] To further optimize the above scheme, the chain plate 2, connecting plate 1, crossbeam 3, and partition plate 15 are all integrally injection molded from engineering plastics, a process that facilitates mass production. Specifically, the crossbeam 3 and partition plate 15 are each equipped with multiple weight-reducing holes 17, and the chain plate 2, connecting plate 1, and crossbeam 3 are each equipped with weight-reducing grooves. This reduces material usage and the weight of the cable chain, while also minimizing deformation caused by shrinkage.

[0038] In summary, this utility model has the advantages of simple and compact structure, convenient and quick assembly and disassembly, and low noise. The chain plate, connecting plate, crossbeam, and partition all adopt a prefabricated structure for easy and rapid assembly. The partitions separate the chain plate, connecting plate, and upper and lower crossbeams into cavities for easy classification and installation of cables, oil pipes, air pipes, water pipes, etc. The easily detachable crossbeams allow for installation and maintenance of cables, oil pipes, air pipes, and water pipes without the need for threading, improving work efficiency. The gap between the connecting plate and the chain plate facilitates bending of the cable chain, while the spring clips between the connecting plate and the chain plate reduce friction and vibration, achieving low-noise operation. This utility model has a simple and compact structure, convenient and quick assembly and disassembly, and low operating noise, making it suitable for high-frequency reciprocating motion scenarios.

[0039] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
