A slot 564 is provided on the outer side of the roller core 563. A fixing nut 565 is screwed on the outer side of the roller core 563.

[0026] As a further implementation of this solution, the included angle between the vertical plate 41 and the bottom support plate 44 is 90°, and a number of first bolts 42 are provided, each of the first bolts 42 being parallel to each other. The included angle between the first bolts 42 and the vertical plate 41 is 90°, and the number of first nuts 43 corresponds one-to-one with the number of first bolts 42. This design can strengthen the mutual support between components and improve the stability of the device.

[0027] As a further implementation of this scheme, four curved grooves 2 are provided, which are symmetrically distributed in front, back, left and right on the inner side of the cable tray body 1. Four rounded corners 3 are provided, which are located in the four corner areas of the cable tray body 1. This design facilitates the adjustment and modification of components and expands the applicability of the device.

[0028] As a further implementation of this scheme, two vertical brackets 41 are provided, and the two vertical brackets 41 are symmetrically distributed. The outer side of the vertical bracket 41 is attached to the inner side of the cable tray body 1, and the upper end surface of the bottom support plate 44 is on the same horizontal plane as the bottom end surface of the cable tray body 1.

This design can improve the wedge fit between components and make the installation of components more precise.

[0032] Workflow: During installation, the required number of cable tray bodies 1 is determined based on the quantity, type, and wiring requirements of the cables. The installation angle is determined by measuring the building structure. When two cable tray bodies 1 need to be connected end-to-end on the same plane, a vertical clamping plate 41 is placed inside the cable tray body 1, and the cable tray body 1 is placed on the base plate 44, which supports the cable tray body 1. Then, the first bolt 42 is rotated to install it onto the vertical clamping plate 41, and one end of the first bolt 42 passes through the curved groove 2 and is screwed into the first nut 43, ensuring all connections are secure and reliable without loosening. This fixes the supporting component 4 to the cable tray body 1. When a certain angle is required at the connection point of two cable tray bodies 1... At the angle, the connecting component 5 can be used to connect the two cable tray bodies 1. After the second bolt 54 passes through the threaded groove 52 and the curved groove 2, it is screwed to the second nut 55. The anti-slip texture on the surface of the second bolt 54 and the second nut 55 is used to enhance the fixation, so that the grooved fixing plate 51 is firmly fixed on the two cable tray bodies 1. Then, the slot 564 is aligned with the limiting groove 53, and the roller frame component 56 is inserted into the grooved fixing plate 51. The fixing nut 565 is rotated to screw the fixing nut 565 to the roller core 563, and the grooved fixing plate 51 is fixed on the roller core 563. The subsequent cable tray bodies 1 are connected to the already spliced ​​cable tray bodies 1 in sequence according to the requirements until the assembly is completed. Then, the cables are laid according to the design requirements to ensure that the cables are neatly arranged and firmly fixed.
