DETAILED DESCRIPTION OF THE EMBODIMENTS

[0013] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments; based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0014] By Figure 1 and Figure 2Provided that, the utility model includes a U-shaped bridge frame body 1 and an n-shaped cover plate 2. The n-shaped cover plate 2 is movably clamped on the top of the U-shaped bridge frame body 1 for dust sealing. Inside the U-shaped bridge frame body 1, there are two movable plates 3 that can be lifted and adjusted. U-shaped cable placement groove plates 4 are fixedly installed at the bottom of the U-shaped bridge frame body 1 and the tops of the two movable plates 3. Lifting and adjusting components 5 are installed between the sides of the opposite sides of the two movable plates 3 and between the sides of the movable plates 3 and the inner bottom of the U-shaped bridge frame body 1. Transmission components 6 are installed between the middle of the bottom of the movable plates 3 and the middle of the two lifting and adjusting components 5 at the bottom of the movable plates 3.

[0015] The four lifting and adjusting components 5 each include a pair of first fixed blocks 7 fixedly installed on the side of the bottom of the movable plates 3. A bidirectional threaded shaft 8 is rotatably connected between the four pairs of first fixed blocks 7. At both ends of the four bidirectional threaded shafts 8, runners 9 are fixedly installed. On both sides of the surfaces of the four bidirectional threaded shafts 8, moving blocks 10 are equidistantly threadedly connected. At both ends of both sides of the top of one of the movable plates 3 and at both ends of both sides of the inner bottom of the U-shaped bridge frame body 1, second fixed blocks 11 are equidistantly fixedly installed. Connecting bars 12 are rotatably connected between the adjacent moving blocks 10 and the second fixed blocks 11. At the middle of the four bidirectional threaded shafts 8, first bevel gears 13 are fixedly installed. At the middle of the bottom of the two movable plates 3, a pair of third fixed blocks 14 are fixedly installed. Between each pair of third fixed blocks 14, a rotating rod 15 located between the two first bevel gears 13 is rotatably installed. At both ends of the two rotating rods 15, second bevel gears 16 are fixedly connected. The four second bevel gears 16 are respectively meshed with the first bevel gears 13, so as to effectively adjust the distance between the movable plates 3.

[0016] When it is necessary to adjust the distance between the upper and lower layers of the adjacent two U-shaped cable placement groove plates 4, by rotating any one of the runners 9 at the lower part of the movable plate 3, the bidirectional threaded shaft 8 on this runner 9 rotates. The rotation of this bidirectional threaded shaft 8 drives the first bevel gear 13 thereon to rotate. The rotation of this first bevel gear 13 drives the rotating rod 15 to rotate through the second bevel gear 16 meshed with it. The rotation of the rotating rod 15 drives another second bevel gear 16 to rotate. The rotation of another second bevel gear 16 rotates the first bevel gear 13 and another bidirectional threaded shaft 8 at the lower part of the movable plate 3 meshed with it. Finally, the two bidirectional threaded shafts 8 at the bottom of the movable plate 3 rotate synchronously. The rotation of the bidirectional threaded shaft 8 makes the moving blocks 10 on both sides of it move away from each other. The movement of the moving blocks 10 pushes the movable plate 3 to move upward through the fixed second fixed blocks 11 and the rotatable connecting bars 12. The upward movement of the movable plate 3 drives the U-shaped cable placement groove plate 4 to move upward, so as to adjust the distance between the upper and lower layers of the adjacent two U-shaped cable placement groove plates 4, making the connection or arrangement of the cables inside the upper and lower U-shaped cable placement groove plates 4 more convenient.

[0017] This cable tray structure has a multi-layer telescopic adjustment function. It can adjust the distance between the upper and lower layer cables according to the layout and connection requirements of the cables, making the connection or layout operation between the upper and lower layer cables more convenient and efficient. Thus, the applicable range of the cable tray is effectively improved. At the same time, the design of this cable tray structure is simple, the use and operation are convenient, and the adjustment is stable and reliable. Its performance can meet the usage requirements of cable laying.
