Abstract

The invention relates to the field of electric power safety, in particular to a combined type special wall drill for low-voltage household connecting lines. The wall drill comprises an arch-shaped support and an eye pull tab support, wherein clamping devices are inserted into the arch-shaped support and the eye pull tab support; the arch-shaped support is connected to outer wall bolts through boltholes and is used as a straight wall drill; the eye pull tab support is connected to the outer wall bolts through the bolt holes and is used as a terminal wall drill; and the arch-shaped support andthe eye pull tab support are combined as a corner wall drill. The wall drill can be suitable for carrying of low-voltage household connecting lines under various conditions, and is safe and convenient; the clamping devices are arranged at a plurality of positions on the wall drill, and a wiring space is reserved, so that the different low-voltage household connecting lines can be separated in order, the phenomena of mutual lap joint, cross and spanning are avoided, and furthermore, an unsaturated polyester acrylate hydrophobic coating coats the surface of the wall drill, the hydrophobicity ofthe wall drill is improved, and the rust or corrosion caused by long-term outdoor exposure is effectively prevented.

Description

technical field [0001] The invention relates to the field of electric power safety, in particular to a combined low-voltage household connecting line special wall brazing. Background technique [0002] The existing wall brazing has only one channel for the connection of low-voltage households. The weak current units such as mobile, telecommunications, and radio and television can only be erected in disorder on the power lines, which is prone to overlapping, crossing, and crossing. There are many self-built houses, and the layout of the lines is relatively messy, which brings great hidden dangers to the safe operation of the household connection line. , the arrangement is irregular, so it is necessary to design a variety of wall joints to deal with different arrangements and situations of self-built houses. However, most of the existing wall joints are only suitable for one situation. However, the amount of different types of wall joints is unknown during construction. It de...
