[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-3 This utility model provides a technical solution: a fiberglass support cable tray structure, including a support frame 1, a slider 2 and a fiberglass cable tray 3. The support frame 1 is provided with a sliding groove 4, and the slider 2 is slidably connected in the sliding groove 4. A transverse fiberglass cable tray 3 is fixed on the outside of the slider 2. Fixing plates 5 are installed on the top and bottom of the slider 2, and the fixing plates 5 are located outside the support frame 1. A coaxial support plate 6 is fixed inside the fiberglass cable tray 3. Several wire grooves 7 are arranged side by side on the support plate 6. A bottom plate 8 is provided at the bottom of the support plate 6. A pressure plate 9 is provided at the top of the support plate 6. A pressure cover plate 10 is pressed onto the top of the fiberglass cable tray 3.

[0019] The bottom of the pressure plate 9 is connected to the base plate 8 via a telescopic column 11. A spring 12 is sleeved at the bottom of the telescopic column 11. The telescopic column 11 passes through the support plate 6. A rotating screw 13 is provided on the pressure plate 10. The bottom end of the rotating screw 13 passes through the pressure plate 10.

[0020] The bottom of the telescopic column 11 is connected to the base plate 8 via a spring 12. When the pressure plate 9 is pressed down, the telescopic column 11 moves down and the spring 12 at the bottom of the telescopic column 11 contracts.

[0021] Heat dissipation holes 14 are provided on the outer surfaces of both sides of the fiberglass cable tray 3.

[0022] The top of the fiberglass cable tray 3 is hollow. The fiberglass cable tray 3 and the cover plate 10 are slidably connected and fixed with bolts, so that the cover plate 10 can be easily slid outward when it is disassembled.

[0023] When the rotating screw 13 rotates downwards, the bottom of the rotating screw 13 presses against the pressure plate 9 downwards.

[0024] In this structure, the fiberglass cable tray 3 and the cover plate 10 are separate structures. During assembly, the bolts on the cover plate 10 are removed, and the cover plate 10 is slid outward from the top of the fiberglass cable tray 3 or lifted upward to separate it. The fiberglass cable tray 3 has a support plate 6 fixed inside along its length. Several horizontally arranged wire grooves 7 are arranged in rows on the support plate 6. The wire grooves 7 are semi-circular grooves, and each wire groove 7 is used for placing cables.

[0025] There is a pressure plate 9 on the top of the tray 6 and a base plate 8 at the bottom of the tray 6. The two sides of the base plate 8 are fixed to the inner wall of the fiberglass cable tray 3. The bottom of the pressure plate 9 is supported by a telescopic column 11. The bottom of the telescopic column 11 passes through the tray 6, and a spring 12 is sleeved at the bottom end of the telescopic column 11. Multiple telescopic columns 11 are arranged according to the length of the cable tray.

[0026] After the cables are inserted into the different grooves 7 on the corresponding tray 6, the pressure plate 10 is slidably installed on the top of the fiberglass cable tray 3, and then the pressure plate 10 and the fiberglass cable tray 3 are fixed with bolts. There are two rotating screws 13 on the top of the pressure plate 10. By rotating the rotating screws 13, the rotating screws 13 rotate and move downward on the top of the pressure plate 10 until the bottom end of the rotating screws 13 slowly moves downward and contacts the pressure plate 9, pressing the pressure plate 9 downward. At this time, the pressure plate 9 presses on the multiple parallel grooves 7 to prevent the cables from easily coming out of the grooves 7. The heat dissipation holes 14 on both sides of the fiberglass cable tray 3 are used to ventilate and dissipate heat for the fiberglass cable tray 3.

[0027] The installation height of the fiberglass cable tray 3 can be adjusted up and down in the slide groove 4 of the support frame 1 by the slider 2, and the height can be locked on the wall by the fixing plate 5.

[0028] After removing the cover plate 10 from the fiberglass cable tray 3, rotate the rotating screw 13 on the cover plate 10 in the opposite direction to remove it. The pressure plate 9 will move upward under the action of the spring 12, that is, it will move upward from the multiple wire grooves 7, making it convenient to take the cable out from the wire groove 7 of the semi-circular groove.
