[0025] In order to solve the problem that when a freely bendable cable bridge is in use, it is not convenient to flexibly adjust the angle of the cable bridge, which reduces the convenience of use of the cable bridge, please refer to Figures 1 to 4 , the structure of the device body is such that a bridge main body 1 for laying cables and being freely bendable is provided. The provided bridge main body 1 presents an inverted U-shaped structure, which is convenient for installing and laying cables on the inner bottom wall of the bridge main body 1, so that the bridge main body 1 provides a supporting effect on the laid cables. The adjacent sides of the bridge main body 1 are rotatably connected to each other through a pin shaft, which is convenient to realize the relative rotation of the two bridge main bodies 1, adapt to the bending angle requirements of the cables for the cable bridge, and improve the convenience of use of the cable bridge. The two side surfaces of the bridge main body 1 are fixedly connected with limit plates 2 with hollow interiors. The inner side walls of the limit plates 2 are slidably connected with a moving plate 3. The provided limit plates 2 fix the moving path of the moving plate 3 and improve the moving stability of the moving plate 3. A chute is opened on one side of the limit plate 2 away from the bridge main body 1, and a movable plate 4 is slidably connected to the inner wall of the chute of the limit plate 2.

[0026] The side of the movable plate 4 is welded to the moving plate 3. The movable plate 4 and the moving plate 3 are combined into a side-mounted T-shaped structure. The right-view height of the set moving plate 3 is greater than the right-view height of the movable plate 4 to prevent the moving plate 3 from separating from the movable plate 4, further fixing the moving paths of the moving plate 3 and the movable plate 4, and improving the structural stability of the components of the cable tray. On the side of the movable plate 4 away from the moving plate 3, a limiting bearing 5 is fixedly connected by embedding. An interference fit is arranged between the inner ring of the limiting bearing 5 and a rotating block 6. The set limiting bearing 5 fixes the rotating position of the rotating block 6 and realizes the relative rotation of the rotating block 6 and the movable plate 4 at the same time. The end face of the rotating block 6 is in rotational frictional contact with the movable plate 4. On the side of the rotating block 6 away from the movable plate 4 on the same side, a connecting plate 7 is welded. Two bridge bodies 1 are arranged adjacent to the two connecting plates 7. The set connecting plate 7 provides a connecting function, strengthening the relative rotation stability of the two bridge bodies 1 during the transmission process, and facilitating the flexible angle bending adjustment of the two bridge bodies 1 at the same time, adapting to the bending angle requirements of the cables laid and installed for the cable tray, and further improving the use convenience of the cable tray.

[0027] On the side of the rotating block 6 close to the connecting plate 7, it extends out of the inner ring of the limiting bearing 5 to prevent frictional resistance between the connecting plate 7 and other structures, and improve the structural stability of the components of the cable tray. On the top surface of the movable plate 4, a fixing plate 8 is fixedly connected. The side of the fixing plate 8 is slidably connected to the limiting plate 2. On the side of the fixing plate 8 away from the limiting plate 2, a knob 10 is arranged. A threaded rod 9 is welded to the side of the knob 10. The threaded rod 9 is threadedly connected to the fixing plate 8, facilitating the rotation of the knob 10, and then the rotation of the threaded rod 9, causing the threaded rod 9 to move downward along the threaded path of the fixing plate 8. The end face of the threaded rod 9 penetrates the side of the fixing plate 8. One end of the threaded rod 9 away from the knob 10 is fixedly connected to a connecting rod 11. The set connecting rod 11 provides a connecting function. The end face of the connecting rod 11 is fixedly connected to a rubber plate 12. The side of the rubber plate 12 abuts against the bridge body 1. The set rubber plate 12 provides an anti-slip function, preventing the cable tray from shaking and rotating after being bent to a specified angle, and further improving the structural stability of the components of the cable tray. By moving the threaded rod 9 toward the side of the bridge body 1, under the connecting function provided by the connecting rod 11, the extrusion abutting force between the rubber plate 12 and the bridge body 1 is strengthened, further preventing the two bridge bodies 1 from relatively shaking and rotating, and further improving the structural stability of the components of the cable tray. The rubber plate 12 is arranged on the top of the limiting plate 2.

[0028] The control circuit of the controller can be realized by simple programming by those skilled in the art. The provision of power also belongs to the common knowledge in the art. And this utility model is mainly used to protect mechanical devices, so the control method and circuit connection of this utility model will not be explained in detail.

[0029] Working principle

[0030] For this freely bendable cable tray, when in use, the user lays and installs the cables on the inner bottom wall of the tray body 1. Under the connection of the pin shaft, the two tray bodies 1 rotate relative to each other. The limiting plate 2 fixes the moving paths of the moving plate 3 and the movable plate 4. The provided limiting bearing 5 enables the relative rotation of the rotating block 6 and the movable plate 4. The provided connecting plate 7 provides a connecting function, strengthening the relative rotation stability of the two tray bodies 1 during the transmission process, thereby adapting to the bending angle requirements of the cables for the cable tray and improving the usability of the cable tray.

[0031] The provided fixed plate 8 provides a supporting function, causing the knob 10 to rotate, and then driving the threaded rod 9 and the knob 10 to rotate synchronously. The threaded rod 9 moves downward along the threaded path of the fixed plate 8. The provided connecting rod 11 provides a connecting function, causing the rubber plate 12 and the threaded rod 9 to rotate and move synchronously. During the transmission process, it is convenient for the rubber plate 12 to abut against the outer wall of the tray body 1. During the transmission process, it prevents the two tray bodies 1 from relatively shaking and rotating after rotating to a specified angle, thereby improving the structural stability of the components of the cable tray.
