[0025] The cable tray 1, cable laying assembly 2, and connector 3 are installed. By setting the connector 3 on the opposite side of two adjacent cable trays 1, multiple cable trays 1 can be installed in a multi-layer combination. The cable laying assembly 2 is set in the cable tray 1 to arrange various cables in an orderly manner, avoiding the cables from being messy and disorderly, which would affect the subsequent staff to find the cables quickly when repairing them.

[0026] like Figure 2-3As shown, this utility model provides a combined multi-layer cable tray technical solution: the cable tray 1 includes a cable tray base 11 and a cable tray assembly 12. The cable tray base 11 is U-shaped. Protrusions 13 are fixedly connected to the top of the vertical outer wall of the cable tray base 11. L-shaped locking blocks 14 are fixedly connected to the left and right sides of the bottom of the cable tray assembly 12. Through-holes 110 are equidistantly arranged on the lower sides of the front and rear sides of the cable tray base 11 near the protrusions 13 in the vertical direction. A plurality of studs 121 are equidistantly arranged and fixedly connected to the top of the cable tray assembly 12. The outer walls of studs 121 are threaded with nuts 122. The inner walls of the two L-shaped locking blocks 14 engage with the outer walls of the two protrusions 13. The protrusions 13 on the cable tray base 11 and the L-shaped locking blocks 14 on the cable tray plate 12 facilitate fastening the cable tray plate 12 to the top of the cable tray base 11, and also facilitate opening and closing the interior of the cable tray base 11. The bottom of the transverse surface of the cable tray base 11 is fixedly connected to studs 111 in an equal array to the number of studs 121. The outer walls of the studs 111 are threaded with nuts 112.

[0027] like Figure 4 As shown, this utility model provides a combined multi-layer cable tray technical solution: the cable laying assembly 2 includes a connecting rod 21, two fixed sleeves 22, two positioning rings 23, and several annular clamps 24. The outer walls of the left and right ends of the connecting rod 21 are fixedly connected to the interior of the two fixed sleeves 22, and one end of each of the two positioning rings 23 is fixedly connected to the opposite face of the two fixed sleeves 22. Positioning rings 23 are installed on both sides of the connecting rod 21 to limit the placement position of the cables. The outer wall of the connecting rod 21 has a threaded groove 210 near the inner side of the two positioning rings 23. The interior of each of the several annular clamps 24 is threadedly connected to the outer wall of the connecting rod 21. Grooves 240 are provided on both sides of the outer wall of each of the several annular clamps 24. Grooves 240 are provided on the annular clamps 24 to facilitate the rotation of the annular clamps 24 along the threaded grooves 210 on the connecting rod 21 and to adjust the spacing between adjacent annular clamps 24. The ends of the two fixed sleeves 22 that are far apart are fixedly connected to the inner wall of the cable tray base 11.

[0028] like Figure 5As shown, this utility model provides a combined multi-layer cable tray technical solution: the connector 3 includes a U-shaped frame plate 31 and two reinforcing plates 32. The middle of the transverse surface of the U-shaped frame plate 31 is provided with a vertically penetrating insertion hole 310. The two reinforcing plates 32 are set in a V shape. The upper and lower ends of the outer walls of the two reinforcing plates 32 are respectively fixedly connected to the left and right sides of the inner wall of the U-shaped frame plate 31 near the insertion hole 310. The reinforcing plates 32 are set inside the U-shaped frame plate 31 to strengthen the support of the U-shaped frame plate 31. The interior of the two insertion holes 310 are respectively sleeved with the outer walls of stud 111 and stud 2121. Stud 111 and stud 2121 are respectively sleeved into the U-shaped frame plate 31 through the insertion holes 310 and are screwed together with nuts 112 and 122 to complete the assembly between the two cable trays 1.

[0029] The working principle of this type of combined multi-layer cable tray will be explained in detail below.

[0030] like Figure 1-5 As shown, when placing cables, the operator first adjusts the spacing between adjacent annular clamps 24 by rotating the annular clamp 24 along the threaded groove 210 on the surface of the connecting rod 21 using the operating groove 240, according to the thickness of the cable. This allows the adjacent annular clamps 24 to position and clamp the cable surface, arranging different cables neatly and orderly. After the cables are installed, when installing multiple cable trays 1, the stud 121 on the cable tray 1 is first inserted into the U-shaped frame plate 31 through the lower insertion hole 310, and then the stud 121 is screwed together. Then, the stud 111 under another cable tray 1 is inserted into the upper insertion hole 310, and then the nut 112 is screwed together to connect the two cable trays 1. Through the above installation method, multiple cable trays 1 can be assembled and connected in multiple layers.

[0031] The specific types and structures used are all existing products, and the specific circuit connection structure and control relationship are all existing technologies, so they will not be elaborated on here.

[0032] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
