Abstract

The invention relates to a replacement-free fixing device for an electric junction box buried in wall in a concealed manner. The replacement-free fixing device comprises a fixing clamp body, a slidable inverted trapezoidal block and a bolt, wherein the fixing clamp body is a rectangular frame body comprising an internally-embedded inverted trapezoidal frame, the slidable inverted trapezoidal block is clamped in the internally-embedded inverted trapezoidal frame, the bolt penetrates through the fixing clamp body to be connected with the slidable inverted trapezoidal block, the slidable inverted trapezoidal block is driven to slide in the internally-embedded inverted trapezoidal frame up and down; when the replacement-free fixing device is used, the fixing device is arranged in the electric junction box and is closely fitted to the inner side wall of the electric junction box, the slidable inverted trapezoidal block is pushed downwards by the bolt to extrude the side edge of the internally-embedded inverted trapezoidal frame, the rectangular frame body is deformed and two sides of the rectangular frame body are enabled to be closely fitted to the electric junction box, and the electric junction box and the rectangular frame body are fixed together through friction force generated by extrusion. According to the replacement-free fixing device, the whole electric junction box is replaced without hole cutting on the wall, the maintaining time is improved, the used material is simple, the cost is reduced and the environmental protection requirement is met.

Description

technical field

[0001] The invention relates to a buried electric junction box in a wall, in particular to a replacement-free fixing device for a buried electric junction box in a wall. Background technique

[0002] The buried junction box is an indispensable electrical device in various buildings. It is usually fixed by drilling holes on the box body and fixing it with bolts. However, the buried junction box is often damaged during construction and daily use. In particular, the nuts fixing the panel cannot be used after falling off. At this time, the wall needs to be chiseled to take out the electrical junction box. First, it affects the appearance of the wall, and second, it increases the workload and construction waste.

[0003] Existing solutions such as Chinese patent CN103401192A provide a kind of fixed card for the electric junction box buried in the wall without replacement. Buried in the electrical junction box, the disadvantage of this patent is that it is not eas...
