Cleaning-free wire box protection device

A cleaning-free wire box protection device relates to the technical field of mechanical and electrical installation and comprises a cubic supporting box body with an open front end, the supporting box body is made of metal materials, a cross-shaped supporting frame is arranged in the supporting box body, the end portion of the cross-shaped supporting frame abuts against the inner surface of the side wall of the corresponding supporting box body, and the end portion of the cross-shaped supporting frame abuts against the inner surface of the side wall of the supporting box body. And the supporting box body forms an internal supporting structure of the wire box to be pre-embedded. The supporting box can be used in a turnover mode, after a wall formwork is removed, the supporting box body can be taken out and put into secondary use, wire box cleaning and garbage recycling in the later period are avoided, the construction cost is saved, and environmental protection is better facilitated. 一种免清理的线盒保护装置，涉及机电安装技术领域，包括
