Detailed Implementation

[0028] 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.

[0029] like Figure 1As shown, this utility model embodiment provides a small bridge-type side-opening cable chain. The cable chain includes several chain link bodies 1 and connectors 2 and 3 at both ends. The chain link bodies 1 are sequentially connected end-to-end. Connectors 2 and 3 are rotatably connected to adjacent chain link bodies 1. The chain link body 1 has an openable assembly structure with an outer crossbeam 10, which facilitates the assembly and laying of cables and various pipelines, and also facilitates later maintenance. In specific manufacturing, the chain link body 1 and connectors 2 and 3 at both ends are injection molded from reinforced nylon material, which can improve its comprehensive mechanical properties, while being lightweight and achieving low-noise operation.

[0030] In specific embodiments of this utility model, such as Figure 2 , 3 As shown, the main body 1 of the chain link includes two parallel chain plates 11 on both sides. The top middle positions of the two chain plates 11 are connected by an openable crossbeam 10, and the bottoms of the two chain plates 11 are connected by a support plate 12. The support plate 12 and the two chain plates 11 are an integral structure. One end of the crossbeam 10 is rotatably engaged with a rotating shaft in the mounting groove 4 at the top of one chain plate 11. The other end of the crossbeam 10 is provided with two parallel claws 5, which are used to clamp the top position of the other chain plate 11. The crossbeam can be opened to lay cables and various pipelines; after assembly, the claws can be pressed and locked onto the top of the other chain plate.

[0031] In the specific production process, such as Figure 4 , 5 As shown, the chain link 11 has a groove 6 in the middle of its top. The inner side of the groove 6 has a recess for accommodating the inner claw 5. The bottom surface of the recess is an inwardly sloping surface 7, and the inner edge of the bottom of the groove 6 has an inwardly sloping guide surface 8. This structure provides space for the claw, facilitating its smooth insertion into the groove. Furthermore, shoulders are provided on both sides of the crossbeam, which can abut against the inner openings of the mounting groove and recess, thereby improving the stability of the connection.

[0032] As a preferred option, such as Figure 3 , 6As shown in Figure 7, several chain links 11 are rotatably connected end-to-end via a snap-fit ​​structure. The connecting end of the first connector 2 is rotatably connected to the first chain link 11, and the connecting end of the second connector 3 is rotatably connected to the last chain link 11. One end of each chain link 11 has a semi-circular edge, and the other end has a fan-shaped limiting groove 9. The snap-fit ​​structure includes a positioning shaft 13 and a corresponding positioning hole 14. The positioning shaft 13 is located on the side of the connecting end of the first connector 2 and in the middle of the recessed platform 15 on the outer side of one end of the chain link 11. The positioning shaft 13 on the chain link 11 is located at the root of the limiting groove 9. The sidewall of the recessed platform 15 is arc-shaped to match the semi-circular edge of the adjacent chain link 11 end. The positioning hole 14 is located at the center of the semi-circle of the other end of the chain link and at the connecting end of the second connector 3. The inner side of the positioning hole 14 on the chain link 11 has a recessed platform 16, and the middle of the sidewall of the recessed platform 16 has a wedge-shaped limiting block 17 that mates with the limiting groove 9. When assembling the main body of the chain link and the connectors at both ends, insert the positioning shaft into the positioning hole and place the limiting block in the limiting groove. As the cable chain bends, the positioning shaft rotates relative to the positioning hole, and the limiting block can slide in the limiting groove. The degree of bending of the cable chain is controlled by the central angle of the limiting groove.

[0033] In specific design, such as Figure 6 As shown, the connector 2 includes a first connecting plate 20 arranged side by side on both sides and a cover plate 21 on top. One end of the first connecting plate 20 is arc-shaped, and a positioning shaft 13 is provided on the outer side of the center of the arc, which is used to cooperate with the positioning hole 14 at the end of the adjacent chain piece 11. The arc-shaped end edge of the first connecting plate 20 is provided with two fan-shaped grooves 18, which are used to cooperate with the limiting block 17 at the end of the adjacent chain piece 11. The other end of the first connecting plate 20 is rectangular, and its bottom edge is tangent to the arc-shaped edge of the other end. The cover plate 21 has a protruding comb-shaped plate 19 in the middle, which is used to fix the cable and ensure that the cable is arranged neatly and orderly. By cooperating with the limiting block and the fan-shaped grooves at different positions, the connection angle between the connector and the mechanical equipment can be adjusted.

[0034] like Figure 7 As shown, the connector 3 includes a second connecting plate 30 arranged side by side on both sides and a bottom plate 31 at its bottom. One end of the second connecting plate 30 is arc-shaped, and a positioning hole 14 is provided at the center of the arc for cooperating with the positioning shaft 13 at the end of the adjacent chain piece 11. The other end of the second connecting plate 30 is rectangular, and its bottom edge is tangent to the arc edge of the other end. The bottom plate 31 has a protruding comb-shaped plate 19 in the middle for fixing the cable and ensuring that the cable is arranged neatly and orderly.

[0035] Further optimizing the above scheme, both connector 2 and connector 3 are integral structures, and weight-reducing holes 22 are provided on both the cover plate 21 and the bottom plate 31; the chain plate 11 of the chain link body 1, the support plate 12, the crossbeam 10, connector 2 and connector 3 are all integrally injection molded from nylon material. This process facilitates mass production; connector 2 and connector 3, with the help of weight-reducing holes, can reduce material usage and weight.

[0036] 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.
