Description

Technical Field

[0001] The invention relates to the technical field of fireproof blocking, in particular to a fireproof blocking mechanism for wiring. Background Art

[0002] Fireproof sealing of wiring is a crucial link in building electrical safety. Its core purpose is to effectively prevent fire and smoke from spreading inside the distribution equipment through cables, pipes and other penetrating objects when a fire occurs. Fireproof mud or fireproof sealant is used to seal the inlets and outlets of distribution boxes and cabinets to prevent fire from entering the distribution box through cable gaps and causing electrical fires.

[0003] Existing fireproof plugging usually selects suitable fireproof materials to seal the cables at the blocking position. The blocking operation is relatively troublesome. When replacing and maintaining the cables, the fireproof materials are attached to the outside of the cables, which makes it inconvenient to disassemble the cables and unable to replace the cables in time, affecting the subsequent normal use.
