[0023] Please refer to Figures 1-4, in the present utility model, a lightweight and high-strength molded grid-type cable tray includes a U-shaped tray body 1. A set of weight-reducing ventilation holes 2 are provided on both the front and the back of the U-shaped tray body 1. A set of weight-reducing grids 3 are provided on the bottom surface of the U-shaped tray body 1. A dust-proof cover 4 is provided above the U-shaped tray body 1. Two reinforcing strips 5 are fixedly connected to the bottom surface of the U-shaped tray body 1. Two clamping plates 6 are fixedly connected to the bottom surface of the dust-proof cover 4. A clamping block 7 is fixedly connected to each side surface of the two clamping plates 6 away from each other. A clamping groove 8 is provided on the upper surface of the U-shaped tray body 1. A groove 9 is provided on the inner side wall of the clamping groove 8. By using the U-shaped tray body 1 and the reinforcing strips 5, it is convenient to lay cables, and at the same time, the bearing capacity of the U-shaped tray body 1 can be improved. In combination with the weight-reducing ventilation holes 2 and the weight-reducing grids 3, not only can more cables be loaded, but also the weight of the U-shaped tray body 1 can be reduced. By making the dust-proof cover 4 match the U-shaped tray body 1, the clamping plates 6 match the clamping grooves 8, and the clamping blocks 7 match the grooves 9, it is convenient to install the dust-proof cover 4 on the U-shaped tray body 1 and limit it at the same time. In addition, it is convenient to shield the cables, improving the protection of the cable performance.

[0024] The inner side wall of the reinforcing strip 5 is in an inner T shape. An anti-rust layer is sprayed on the outer surface of each reinforcing strip 5. By making the reinforcing strip 5 in an inner T shape and setting an anti-rust layer on the outer surface of the reinforcing strip 5, the strength of the U-shaped tray body 1 can be increased. The clamping groove 8 matches the clamping plate 6, and the groove 9 matches the clamping block 7. By using the clamping groove 8 and the clamping plate 6 to be connected in cooperation, and the groove 9 and the clamping block 7 to be clamped, it is convenient to install the dust-proof cover 4 on the U-shaped tray body 1. Two anti-tensile reinforcement plates 10 are fixedly connected to the inner side wall of the U-shaped tray body 1. The bottom surface of each anti-tensile reinforcement plate 10 is fixedly connected to the inner bottom wall of the U-shaped tray body 1. By providing the anti-tensile reinforcement plates 10, the loading capacity of the U-shaped tray body 1 can be improved under the rated load condition by using the anti-tensile reinforcement plates 10.

[0025] A galvanized layer is sprayed on the outer surface of the U-shaped tray body 1. The production batch number is engraved on the upper surface of the dust-proof cover 4. By spraying a galvanized layer on the outer surface of the U-shaped tray body 1 and engraving the production batch number on the surface of the dust-proof cover 4, the corrosion resistance of the U-shaped tray body 1 can be improved, and at the same time, it is convenient to know the production date of the device. The weight-reducing grid 3 is rectangular. The U-shaped tray body 1 matches the dust-proof cover 4. By making the weight-reducing grid 3 rectangular so that the U-shaped tray body 1 and the dust-proof cover 4 are of matching sizes, it is convenient to reduce the weight of the U-shaped tray body 1 and improve the strength of the U-shaped tray body 1.
