[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The present utility model aims to solve the problems that the bearing capacity is relatively low relying only on the strength of the frame itself, it is prone to deformation due to external forces, which is not conducive to protecting the safety of the internal cables. At the same time, the aluminum alloy cable tray frame uses connecting pieces to connect the top and the bottom, and the connection part is relatively fragile and easy to break and fall off when encountering external forces. It provides a combined aluminum alloy cable tray structure as shown in Figures 1 - 3 Figure 4, which includes a bottom plate 1. On both sides of the top surface of the bottom plate 1, side plates 11 are fixedly connected. At the top of the side plates 11, there is a top plate 2. A reinforcing plate 21 is fixedly connected to the bottom surface of the top plate 2. The inner wall of the reinforcing plate 21 is arched. On both sides of the top surface of the bottom plate 1, sliding grooves 14 are opened. Both ends of the bottom of the reinforcing plate 21 are slidably connected to the sliding grooves 14. Both sides of the outer wall of the reinforcing plate 21 are in close contact with the inner walls of the two side plates 11; the bottom plate 1 and the side plates 11 form a concave-shaped integral frame structure, and the top plate 2 and the reinforcing plate 21 form a top structure. During the installation process, both ends of the bottom of the reinforcing plate 21 slide in the sliding grooves 14 to assist in positioning and ensure the accuracy of the installation of the cable tray. At the same time, due to the arched shape of the reinforcing plate 21, the outer wall of the reinforcing plate 21 is in close contact with the inner wall of the side plate 11 and is inserted into the sliding groove 14. When subjected to pressure extrusion from both sides, the reinforcing plate 21 can withstand the pressure from both sides, avoid the deformation of both sides of the cable tray caused by external forces, enhance the lateral stability, and the arched support can evenly disperse the pressure structurally, so it has a higher bearing capacity and becomes a support for resisting longitudinal pressure, ensuring the longitudinal stability. The setting of the reinforcing plate 21 strengthens the overall strength inside the cable tray and guarantees the safety of the internal cables.

[0025] In the present utility model, on the top of the sides of the two side plates 11 close to each other, clamping plates 15 are fixedly connected. Between the top plate 2 and the reinforcing plate 21, there are two slotted openings 22. The clamping plates 15 are inserted into the slotted openings 22; by inserting the clamping plates 15 into the slotted openings 22, the cooperation of the clamping plates 15 and the slotted openings 22 fixes the bottom plate 1, the side plates 11, the top plate 2 and the reinforcing plate 21 together to form the entire cable tray, and the installation is convenient and fast.

[0026] Furthermore, on the bottom surface of the ends of the two clamping plates 15 close to each other, bending parts 16 are fixedly connected. On the bottom surface of the sides of the two slotted openings 22 close to each other, bending grooves 23 are opened. The bending parts 16 are inserted into the bending grooves 23; due to the hooked shape of the bending parts 16, after the bending parts 16 are inserted into the bending grooves 23, the connection part is strengthened and will not break and fall off due to external forces, making the cable tray more stable and avoiding the shaking of the top plate 2 and the reinforcing plate 21.

[0027] In the present utility model, a plurality of reinforcing ribs 13 are fixedly connected to the outer wall of the side plate 11, and the reinforcing ribs 13 are hollow strip-shaped shells; the hollow structure of the reinforcing ribs 13 can reduce the overall weight of the cable tray, and the setting of the reinforcing ribs 13 strengthens the external strength of the side plate 11.

[0028] In the present utility model, a plurality of through holes 12 are uniformly and penetratingly formed in the top surface of the bottom plate 1; the through holes 12 can help the internal cables dissipate heat, avoid overheating of the cables, and reduce the probability of cable aging.

[0029] In the present utility model, threaded rods 3 are threadedly connected to both sides of the top plate 2 and the reinforcing plate 21. The bottom end of the threaded rod 3 is rotatably connected to a pressing plate 31; after the cable is installed in the cable tray, the threaded rod 3 is rotated, and the rotation of the threaded rod 3 drives the pressing plate 31 to move. The pressing plate 31 contacts the cable and fixes it.

[0030] It should be noted that the pressing plate 31 is located between the inner walls of the reinforcing plate 21, and the pressing plate 31 is an elastic arc-shaped plate structure; the elastic structure of the pressing plate 31 can reduce the pressure of the pressing plate 31 on the cable, avoid damage to the cable, and at the same time, after the pressing plate 31 contacts and fixes the cable, it can also prevent the top plate 2 and the reinforcing plate 21 from moving.
