Fireproof and heat-insulating heavy-duty cable protection pipe

Abstract

This utility model belongs to the technical field of cable protection equipment, specifically a fireproof and heat-insulating heavy-duty cable protection pipe. It includes a cable core, with a waterproof layer and a fireproof layer respectively provided on the outer side of the insulation layer. A protective layer is provided on the outer side of the fireproof layer. A connecting plate is provided on the surface of the protective layer, and a connecting box is provided on the outer side of the connecting plate. The surface of the connecting box has a connecting groove and a limiting groove. The interior of the connecting box is provided with a limiting guide rod, a limiting plate, a limiting spring, and a pull plate. This fireproof and heat-insulating heavy-duty cable protection pipe, by using a connecting plate and a connecting box, allows the connecting plates at both ends of two cable protection pipes to be connected and limited by the limiting plate inside the connecting box. This uses multiple short cable protection pipes to protect the surface of a long cable, solving the technical problem of existing cable protection methods that use a single cable protection pipe the same length as the cable, making installation or disassembly of the protection pipe inconvenient.
