[0002] Cable trough, also known as wiring trough, distribution trough, and line trough (varies from place to place), is an electrical tool used to organize power cables, data cables and other wires in a standardized manner and fix them on the wall or ceiling. According to different materials, cable troughs are divided into many types, commonly used ones include environmentally friendly PVC cable trough, halogen-free PPO cable trough, halogen-free PC / ABS cable trough, steel and aluminum and other metal cable troughs, etc.

[0003] Some floor cable ducts currently on the market: for example, the utility model patent with authorization announcement number CN212518282U discloses a waterproof and pressure-resistant floor cable duct, which is provided with an L-shaped notch at the upper end of the bottom trough, an L-shaped mounting block matching the L-shaped notch under the cover plate, and a sealing rubber pad between the two to enhance the air tightness between the cover plate and the bottom trough, thereby achieving a good waterproof effect. However, since the cable trough is relatively sealed as a whole and lacks a breathable structure, the heat generated by the cables cannot be effectively dissipated, resulting in heat accumulation, reducing the service life of the internal cables and increasing the risk of electrical failure.

[0004] Therefore, we propose a waterproof ground cable trough that is waterproof, breathable and heat-dissipating, so as to solve the above-mentioned problems. Utility Model Content

[0007] Furthermore, the wire fixing mechanism comprises a special-shaped plate, both ends of the special-shaped plate are connected with connecting columns, and a plurality of U-shaped wire fixing grooves are arranged on the special-shaped plate, and one end of the connecting column is fixed to the placement box.

[0008] Furthermore, the outer side surface of the drainage box is configured as an inclined structure.

[0009] Furthermore, the inner bottom wall of the cable trough box is symmetrically arranged as a slope structure with the support plate as the center, and a plurality of water holes are opened on the support plate.

[0010] Furthermore, the fixing mechanism includes a mechanism tube fixed to the side of the cover plate, a limit plate and a compression spring are arranged in the mechanism tube, a fixed clamping block is connected to the side of the limit plate, and a pulling wire is connected to the other side of the limit plate, a pull ring connected to the pulling wire is arranged on the outside of the mechanism tube, and fixed clamping grooves are opened on both side surfaces of the wire trough box near both ends, and the fixed clamping grooves are slidably connected to the fixed clamping block.

[0011] Furthermore, the lower surface of the fixed block is configured as an arc-shaped structure.

[0012] The beneficial effects of the utility model are as follows: a placement box is fixed on the top of the support plate of the bottom wall of the line trough box, a plurality of line fixing mechanisms are arranged in the placement box, drainage boxes are arranged at positions near the bottom on both sides of the line trough box, and a plurality of drainage holes are opened on the sides of the drainage box, a water retaining disc is hinged on the outer side of the drainage box, and a plurality of first heat dissipation holes are symmetrically opened on both side surfaces of the line trough box, a plurality of second heat dissipation holes are opened on both side surfaces of the placement box near the top, so that the second heat dissipation holes are located above the first heat dissipation holes, when liquid enters the line trough box through the first heat dissipation holes, it will fall into the bottom of the line trough box, when there is too much liquid, the water retaining disc will be pushed open and flow out from the drainage holes, thereby playing a waterproof role, and at the same time, the provision of the first heat dissipation holes and the second heat dissipation holes improves the air permeability, can dissipate heat, and prevent heat accumulation.
