The invention provides an embedded junction box opening plastering device which comprises a hollow column, a plurality of movable plates, a plurality of retaining sheets and a spring mechanism. The upper half portion of the hollow column is provided with a plurality of windows, the lower half portion of the hollow column is provided with a plurality of containing grooves, and each containing groove is used for containing threaded-hole posts in an embedded junction box; the movable plates are mounted in the windows of the hollow column through hinges respectively, and each movable plate is capable of rotating around one own side; the retaining sheets are mounted at the edges of the movable plates respectively to prevent the movable plates rotating outwards from extending out of the outer lateral side of the hollow column; and the spring mechanism is contained in the hollow column and applies outward force to each movable plate. The shape and size of the outer lateral side of the hollow column enable the outer lateral side of the hollow column to be in close fit with the inner wall of the embedded junction box when the hollow column is inserted into the embedded junction box. Using the embedded junction box opening plastering device can conveniently form a qualified plastered opening shape for one time when an embedded junction box opening is plastered.
Description
technical field [0001] The invention relates to the field of construction engineering, in particular to a plastering forming device for a box opening of a pre-embedded wire box. Background technique [0002] There are many electrical switches and / or sockets installed on the walls of civil and industrial housing buildings, the panels of these electrical switches and / or sockets are exposed outside the wall, and the electrical structures of these electrical switches and / or sockets accommodate In the pre-buried wire box in the wall behind the panel. At present, the pre-embedded wire box generally adopts the 86-type wire box. figure 1 is a schematic perspective view showing an example of a Type 86 wire box. Such as figure 1 As shown, the so-called 86-type wire box is basically a square box without a cover 1, wherein screw holes 2 are arranged on the two opposite inner walls of the box. The 86-type wire box is pre-buried in the wall, and the box mouth Facing outwards, the box ...
