[0002] Cable fireproof trough boxes are usually made of metal materials, and their structural design mainly includes two parts: the box body and the cover plate. The box body is an open rectangular structure used to accommodate cables and has certain fireproof functions. The cover plate is used to cover the top of the box body to seal and protect it. The functions of cable fireproof trough boxes are mainly reflected in the following aspects: Fire isolation: In the event of a fire, the cable fireproof trough box can isolate and block the spread of fire, delay the damage of the fire to the cable, and thus protect the cable and surrounding equipment from the fire; Protect cables: The cable fireproof trough box can provide an additional layer of protection to prevent damage to the cable by external objects or the environment, and extend the service life of the cable; Safety isolation: The use of cable fireproof trough boxes can effectively isolate cables from other equipment or environments, reduce fire risks, and ensure the safety of personnel and equipment; Beautiful and neat: The cable fireproof trough box can effectively hide cables, making the cable wiring look more neat and beautiful. Although the cable fireproof trough box will not be ignited by open flames, high temperature will still cause the cable insulation layer inside the cable fireproof trough box to melt and be damaged. Therefore, it is necessary to solve the problem of how to ensure the safety of the internal cables when the cable fireproof trough box is subjected to high temperature. Therefore, we propose a spliced partitioned cable fireproof trough box. Utility Model Content
