When the upper cover body 2 is covered on the cable tray main body 1, the clamping block 21 is inserted into the limit block receiving groove 11, and the movable limit block 121 moves towards the bottom of the limit block sliding groove 12. When the upper cover body 2 is completely covered, the movable limit block 121 is reset through the return spring and is inserted into the limit block fitting groove 211 on the clamping block 21.

[0027] The installation of the cable tray can be more convenient. In the present utility model, the tray body 1 is designed as a U-shaped device with an upward opening. A top cover 2 is provided at the upper opening thereof, and closing covers 3 are installed at the two open ends of the tray body 1. Along the length direction of the tray body 1, a plurality of limiting block receiving grooves 11 are provided. Each limiting block receiving groove 11 is provided with a limiting block sliding groove 12, and a movable limiting block is installed in the limiting block sliding groove 12. These movable limiting blocks 121 are connected to the bottom of the limiting block sliding groove 12 through a return spring, enabling them to move freely and reset. The top cover 2 is provided with clamping blocks 21 equal in number to the limiting block receiving grooves 11. On both sides of each clamping block 21, a limiting block fitting groove 211 is provided. When the top cover 2 is placed on the tray body 1, these clamping blocks 21 will be inserted into the limiting block receiving grooves 11. At this time, the movable limiting blocks 121 will move towards the bottom of the limiting block sliding groove 12 due to the insertion of the clamping blocks 21. Once the top cover 2 is completely covered on the tray body 1, the movable limiting blocks 121 will reset through the action of the return spring, and then be inserted into the limiting block fitting grooves 211 on the clamping blocks 21, thereby realizing the quick locking and fixing of the top cover 2 and the tray body 1. This design makes the installation process of the cable tray more convenient and efficient.

[0028] Refer to Figures 2-5 , Figure 8 and Figure 9 : The top cover 2 is provided with a first snap-in receiving groove 22 and a first snap-in guiding post 24.
