Technical Field

[0001] This application belongs to the field of cable tray technology, specifically a flame-retardant and heat-dissipating galvanized cable tray. Background Technology

[0002] Cable trays are support structures used to support and protect cables, wires, and other wires. They are typically made of metal (such as steel or aluminum) or plastic and are available in various sizes and configurations to suit different installation needs and cable capacities. Cable trays not only effectively organize and manage cables, preventing them from tangling and getting damaged, but also improve the security of cabling systems and facilitate maintenance and repair.

[0003] For example, application CN212183024U discloses a flame-retardant galvanized cable tray, including a frame. The upper surface of the frame has a first sliding groove, and a first sliding block is provided inside the first sliding groove. A sliding cover is provided above the first sliding block. The lower inner surface of the frame has slots, and a buckle is provided inside the slots. A fixing block is provided above the buckle, and a handle is provided inside the fixing block. A clamping block is provided on one side of the handle. Heat dissipation holes are provided on both sides of the frame, and a second sliding groove is provided on both sides of the frame. This flame-retardant galvanized cable tray, through the sliding cover and the first sliding groove, facilitates the opening and closing of the device, making it convenient for workers to open and repair damaged internal parts and cables, improving the practicality of the device and reducing the labor intensity of workers when repairing it.

[0004] However, in this application, the cable tray connection structure is redundant, and thermal deformation is detrimental to the functionality of the cable tray. Utility Model Content

[0005] The purpose of this application is to provide a flame-retardant and heat-dissipating galvanized cable tray to solve the problems mentioned above, such as redundant cable tray connection structures and thermal deformation that is detrimental to the functionality of the cable tray.

[0006] The technical solution adopted in this application is as follows: a flame-retardant and heat-dissipating galvanized cable tray, including a straight frame, a bottom heat insulation plate welded to the outer surface of the lower end of the straight frame, a support strip welded to the inner surface of the lower end of the straight frame, a heat dissipation expansion plate welded to the upper surface of the straight frame, a straight placement frame movably connected to the inner surface of the straight frame corresponding to the support strip, a side fixing hole provided on the outer surface of the straight frame, and a straight connecting plate provided on the inner surface of the side fixing hole.

[0007] By adopting the above technical solution, when exposed to high temperatures, the temperature of the bottom support bar extends to both sides of the straight frame.

[0015] By adopting the above technical solution, the first locking plate and the outer edge support strip support the right-angle placement frame on the inner and outer sides respectively, ensuring the stability of the placement.

[0016] In a preferred embodiment, an auxiliary heat insulation plate is welded to the lower surface of the outer edge support strip, and a second fastening plate is welded to the outer surface of the auxiliary heat insulation plate on the side away from the outer edge support strip.

[0017] By adopting the above technical solution, the auxiliary heat insulation plate is bent to protect the right-angle placement frame at the bottom, and the second fixing plate is bent and inserted between the right-angle placement frame and the first fixing plate to complete the fixation of the second fixing plate.

[0018] In a preferred embodiment, the straight placement rack is made of polyphenylene sulfide, the T-shaped placement rack is made of polyphenylene sulfide, and the right-angle placement rack is made of polyphenylene sulfide.

[0019] By adopting the above technical solution, polyphenylene sulfide (PPS) is a high-performance, high-temperature stable engineering plastic and an excellent flame-retardant material. It possesses superior mechanical properties, chemical corrosion resistance, and heat resistance, and can be used for extended periods at high temperatures without deformation or cracking.

[0020] In a preferred embodiment, the auxiliary supplementary strip is made of aluminum alloy, and the auxiliary heat insulation plate is made of aluminum alloy.

[0021] By adopting the above technical solution, the outer alumina layer of aluminum alloy has good chemical stability, while the aluminum alloy has relatively low hardness, making it easy to bend and form the required shape.

[0022] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0023] In this application, when exposed to high temperatures, the temperature of the bottom support bar extends to both sides of the straight frame. Above, the heat dissipation area is increased by the heat dissipation extension plate to conduct heat out of the straight placement rack as much as possible, ensuring the stability of the cables in the straight placement rack. The side fixing holes ensure external connection while ensuring internal ventilation. The straight connection plate completes the connection of the straight ends of the cable tray, ensuring the extension of the cable tray and facilitating free combination. Attached Figure Description

The side fixing hole 5 ensures external connection while ensuring internal ventilation. The straight connection plate 7 completes the connection of the straight ends of the cable tray, ensuring the extension of the cable tray and facilitating free combination.
