Plumbing box for buried wire wiring for preventing damaged coating

摘要

The present invention is a piping box for wire wiring that is installed on a ceiling slab or wall surface of a building and used to wire wires for electrical and communication purposes. It was developed so that it does not occur, and in composing the piping box for wire wiring, a guide roller that rotates on the opposite side to the opposite inlet and outlet is formed on the periphery of the inlet of each inlet and outlet inside the piping box, and the electric wire passing through the piping box The guide roller is configured to rotate at least one bearing or roller on the shaft so that both ends are supported by force fitting in the shaft coupling part formed around the inlet and outlet of the pipe box to rotate. By composing a piping box for wiring, the friction between the piping box and the electric wire is minimized, so that the wiring proceeds smoothly and the electric wire coating is prevented from being damaged. It is a novel invention that creates the effect of reducing construction costs by reducing labor costs and reducing labor costs.
