The top cover of the cable tray is generally slidably inserted on the top of the cable tray. When the cables inside the cable tray need to be inspected, the entire top cover needs to be pulled to slide on the top of the cable tray. The top cover needs to be completely separated from the cable tray before it can be removed. As a result, the removal of the top cover is greatly affected by the environment. When there are objects blocking the installation location of the cable tray, it is difficult to remove the top cover. Summary of the invention

[0010] Furthermore, the end of the moving rod extends to the outer end of the sliding hole frame, the number of the moving rods is two, the ends of the two moving rods that are close to each other are in contact with each other, the semicircular block is arranged below the moving rod, the surface of the moving rod is adapted to the inner wall of the socket, and the end of the force-bearing rod extends to the outer end of the triangular plate.

[0011] The present invention has the following beneficial effects: After the cable is placed inside the bridge, the present invention places the top cover on the top of the bridge, and the bottom of the top cover slides to below the top of the bridge through the groove. At this time, the surface of the bridge is located at the limiting groove, and the disc uses the elasticity of the tension spring to push the center frame downward.

[0013] The present invention utilizes the force-bearing rod to push the triangular plate to produce deformation, and the triangular plate will push the moving rod to move toward the outer end of the sliding hole frame. When the disc corresponds to the sliding hole frame, the moving rod will utilize the elasticity of the spring to slide into the inside of the insertion hole to fix the disc. At this time, the disc can fix the positioning plate to the center bottom of the top cover, thereby improving the convenience of disassembly of the top cover. When the top cover needs to be fixed to the top of the bridge frame, the moving rod is pushed to separate from the inner wall of the insertion hole, and the disc will utilize the elasticity of the tension spring to move downward to the inside of the round hole rod, and push the positioning plate to move to the limit groove to fix the top cover.

The surface of the disk 11 contacts the inner wall of the round hole rod 6 , and the bottom of the vertical rod 15 passes through the round hole rod 6 and extends to the inside of the bridge frame 2 .

[0021] The surface of the extrusion frame 13 contacts the inner wall of the bridge frame 2. After the cable is placed inside the bridge frame 2, the top cover 1 is placed on the top of the bridge frame 2. The bottom of the top cover 1 will slide to the bottom of the top of the bridge frame 2 through the groove 7. At this time, the surface of the bridge frame 2 will be located at the limiting groove 8. The disc 11 uses the elasticity of the tension spring 17 to push the center frame 10 to move downward. When the center frame 10 moves downward, it pushes the sliding frame 12 to move toward the end of the top cover 1 through the inclined plate 14. At this time, the sliding frame 12 will push the extrusion component 4 to move to the limiting groove 8 and contact the bridge frame 2. The top cover 1 is fixed to the top of the bridge frame 2 by the extrusion component 4.

At this time, the sliding frame 12 will push the extrusion component 4 to move to the limiting groove 8 and contact the bridge frame 2, and the top cover 1 is fixed to the top of the bridge frame 2 by using the extrusion component 4. When the disc 11 moves downward, the vertical rod 15 pushes the extrusion frame 13 to move toward the bottom of the inner wall of the bridge frame 2, and the extrusion frame 13 is used to squeeze and limit the cable to improve the stability of the cable inside the bridge frame 2. When the sliding frame 12 pushes the positioning plate 20 to separate from the top cover 1, the tripod 21 will move upward by utilizing the elasticity of the elastic rod 25. When the tripod 21 moves upward, it pushes the inclined panel 22 to slide inside the sliding hole 23 and contact with the surface of the bridge frame 2.
