[0022] Please refer to Figures 1-4, in the present utility model, the modular expandable molded cable tray includes two tray bodies 1. On the outer surface of each tray body 1, two positioning seats 2 are fixedly connected. In the inner side wall of each positioning seat 2, a groove 3 is provided. Outside each tray body 1, a connecting plate 4 is provided. On the upper surface of each connecting plate 4, a group of clamping plates 5 are fixedly connected. On the side surfaces of each group of clamping plates 5 away from each other, a clamping block 6 is fixedly connected. On the left side surface of each tray body 1, two connecting blocks 7 are fixedly connected. On the right side surface of each tray body 1, two annular positioning plates 8 are fixedly connected. By making the connecting blocks 7 and the annular positioning plates 8 match each other, it is convenient to dock the tray bodies 1 of the pull rod. And by making the clamping plates 5 match the positioning seats 2 and the clamping blocks 6 match the grooves 3, it is convenient to limit the two tray bodies 1, and at the same time improve the fixing property of the tray bodies 1 and avoid the situation of their separation.

[0023] On the bottom surface of each tray body 1, two reinforcing ribs 14 are fixedly connected. On the outer surface of each reinforcing rib 14, an anti-rust layer is sprayed. By providing the reinforcing ribs 14 and spraying the anti-rust layer on the surface of each reinforcing rib 14, the loading capacity of the tray body 1 can be increased by using the reinforcing ribs 14, and at the same time, the situation of the reinforcing ribs 14 rusting can be avoided, improving the service life of the tray body 1 and the reinforcing ribs 14. On the inner side wall of each tray body 1, two fixing plates 13 are fixedly connected. The bottom surface of each fixing plate 13 is fixedly connected to the inner bottom wall of the tray body 1. By providing the fixing plates 13 and the bottom surface of each fixing plate 13 can be fixedly installed on the inner bottom wall of the tray body 1, the loading capacity of the tray body 1 can be improved by using the fixing plates 13, avoiding the situation of the tray body 1 bending and increasing the strength of the tray body 1. On the inner side wall of each tray body 1, a group of weight-reducing holes 10 are provided. On the bottom surface of each tray body 1, a group of heat dissipation holes 9 are provided. By providing the weight-reducing holes 10 and the heat dissipation holes 9, through the cooperation of the weight-reducing holes 10 and the heat dissipation holes 9, the self-weight of the tray body 1 can be reduced, without affecting the loading capacity of the tray body 1, and can assist in dissipating heat from the cable.

[0024] On the upper surface of each tray body 1, two connecting grooves 12 are provided. Above each tray body 1, a cover plate 11 is provided. By providing the connecting grooves 12 and the cover plate 11, through the cooperation of the connecting grooves 12 and the cover plate 11, it is convenient to shield the cables inside the tray body 1. Each annular positioning plate 8 matches the connecting block 7, and each clamping block 6 matches the groove 3, which is convenient to connect the two tray bodies 1.

[0025] The working principle of the present utility model is:

[0026] First, fix a single bridge frame body 1 to the mounting frame. When it is necessary to connect two bridge frame bodies 1, directly insert the connecting block 7 into the annular positioning plate 8, and push the connecting plate 4 so that the clamping plate 5 is inserted into the positioning seat 2. At the same time, the clamping block 6 is engaged with the groove 3. Then, fix the connected bridge frame body 1 to the mounting frame, and at the same time, place the cable into the bridge frame body 1. Immediately afterwards, snap the cover plate 11 into the connecting groove 12 to shield the cable. The above is the entire usage process of the present utility model.
