[0026] Embodiment 1:

[0027] In this embodiment, a cable tray, as Figures 1 to 3As shown in the figure, it includes a bridge frame main body. The above bridge frame main body includes a bottom plate 1 and two side plates 2 connected in a "U" shape. The above bottom plate 1 and the two side plates 2 can be integrally formed by bending a stainless steel plate, with high structural strength and corrosion resistance. The above side plates 2 are provided with a plurality of louver holes 3 along the length direction. The above louver holes 3 have the functions of ventilation and dust prevention. The above bottom plate 1 is provided with a plurality of ventilation holes 4 along the length direction. A first reinforcing rib 5 for enhancing the structural strength of the bottom plate 1 is provided between every two adjacent ventilation holes 4.

[0028] Adopting this structure, three-sided open ventilation is formed through the above louver holes 3 on both sides and the above ventilation holes 4 at the bottom, so as to form an efficient heat dissipation channel in the cable tray, enhance air convection, and greatly improve the heat dissipation effect. The above first reinforcing rib 5 improves the overall rigidity and strength, improves the structural stability, enhances the bearing capacity, and extends the service life, making the practicality of the present utility model stronger.

[0029] As a specific implementation manner of this embodiment, as Figure 3 shown, the above ventilation holes 4 are oblong holes, and a plurality of the above ventilation holes 4 are arranged in parallel and at intervals along the length direction of the above bottom plate 1. Compared with the closed structure, the above ventilation holes 4 improve the ventilation capacity below the above bridge frame main body and form convection channels in three directions with the louver holes 3 on the above side plates 2, improving the heat dissipation capacity.

[0030] In this embodiment, as Figure 3 shown, the above bottom plate 1 is recessed inward on one side to form the above first reinforcing rib 5. The inward recessed direction can be upward or downward. The above first reinforcing rib 5 is parallel to the above ventilation holes 4, and a plurality of the above first reinforcing ribs 5 and ventilation holes 4 are arranged in parallel in sequence. As an optimization, the width of the above first reinforcing rib 5 is the same as the width of the above ventilation holes 4, which not only improves the heat dissipation effect but also ensures the structural strength.

[0031] In this embodiment, as Figure 3 shown, the above first reinforcing rib 5 is provided with a plurality of heat dissipation holes 6 along the length direction. The above heat dissipation holes 6 are arranged along the width direction of the first reinforcing rib 5. The plurality of the above heat dissipation holes 6 further improve the heat dissipation capacity of the above bottom plate 1.

[0032] In this embodiment, as Figure 2 shown, the above side plates 2 are provided with a plurality of round holes 7. The above round holes 7 have both the functions of heat dissipation and connection. The positions and numbers of the above round holes 7 can be determined according to the positions of the hanging brackets or supports to be connected.

[0033] According to a preferred implementation manner, as Figure 4As shown in the figure, it further includes a cover plate 8 and a locking device. A plurality of the above-mentioned locking devices are provided on the upper part of the above-mentioned side plate 2. The above-mentioned cover plate 8 is detachably covered on the tops of the two above-mentioned side plates 2 through the locking device. The above-mentioned cover plate 8 can improve the structural strength of the cable tray, and the above-mentioned cable bridge is fixed on the hanger or bracket through the cover plate 8 and the locking device.

[0034] Specifically, as Figure 4 shown in the figure, the above-mentioned locking device includes a connecting plate 9 and a bolt 10. The bottom end of the above-mentioned connecting plate 9 can be fixed to the outside of the above-mentioned side plate 2 by means of fasteners or welding. The top end of the above-mentioned connecting plate 9 is bent laterally towards the side of the above-mentioned cover plate 8 to form a pressing plate 11. The above-mentioned pressing plate 11 is provided with a screw hole, and the above-mentioned bolt 10 is screwed into the above-mentioned screw hole. During installation, the edge of the hanger or bracket is located between the above-mentioned cover plate 8 and the bolt 10, and then the above-mentioned bolt 10 is tightened so that the above-mentioned cover plate 8 and the bolt 10 tightly clamp the edge of the hanger or bracket, thereby detachably installing the cable tray on the hanger or bracket. As an optimization, the tops of the two above-mentioned side plates 2 are both bent towards each other to form a support plate 13 for supporting the above-mentioned cover plate 8 to increase the contact area with the above-mentioned cover plate 8.

[0035] In this embodiment, the above-mentioned cover plate 8 is concave inward on one side to form a second reinforcing rib 12. A plurality of the above-mentioned second reinforcing ribs 12 are arranged parallel and spaced along the length direction of the cover plate 8. The above-mentioned second reinforcing ribs 12 enhance the rigidity and structural strength of the above-mentioned cover plate 8, thereby improving the overall structural stability and bearing capacity.

[0036] The cable tray of the present utility model reserves the above-mentioned louver holes 3 and heat dissipation holes 6, making it extremely convenient for the cable to dissipate heat. The above-mentioned stainless steel cover plate 8 can play the roles of anti-corrosion, rain-proof, dust-proof, moisture-proof, and anti-interference. The locking device ensures the tight and firm connection between the above-mentioned cover plate 8 and the bridge body, and is convenient for disassembly and assembly, with a neat and beautiful appearance, and can play an efficient heat dissipation role in places with a strong corrosion environment.
