The present invention relates to a wiring device fixing device, and more specifically, to a wiring device fixing device that can simply fix an electric wiring device in a square hole formed in a wall attachment plate during interior wall partition construction by simply tightening two bolts. .

In general, outlets, switches, and connectors are necessary to connect to electric appliances or cut off electricity supply in the indoor wiring of a building. These outlets, switches, and connectors are collectively called wiring appliances, and wiring appliances are embedded and installed in indoor walls.

Additionally, in the process of constructing the walls of a building, a wiring device buried groove is formed into which the wiring device is inserted into the wall of the interior space of the building.

And on the inner side of the partition wall of the indoor space of the building, gypsum board, insulation board, etc. (hereinafter collectively referred to as "partition wall attachment plate"), which have the effect of insulating and noise blocking, are attached to the wall and constructed.

In addition, after constructing the partition wall attachment plate, in order to attach the wiring device embedded in the wall, a square hole for attaching the wiring device is drilled in the partition wall attachment plate at a position corresponding to the wiring device embedding groove.

First, when attaching a wiring device to a wiring device embedding groove through the square hole of the wall attachment plate, a wiring device fixture that is inserted into the square hole and fixed around the square hole is used.

Several types of such wiring fixtures are known and sold on the market, and one example is the “electrical wiring fixture with a double screw fastening support structure” (hereinafter referred to as “conventional wiring fixture”) of Republic of Korea Patent Registration No. 1842090. there is.

A conventional wiring device includes a support in which one or more pairs of support legs extend from a hollow frame formed through the center and a hooking wing protruding outward along the hollow frame, and a pair of supports facing each other on the support. It includes a fixing plate with guide protrusions on both sides fitted so as to be movable along a guide groove formed on the inside of the leg, and a tightening screw that penetrates the fixing plate through the support and is screwed to move the fixing plate along the guide groove.

Therefore, when installing the support that constitutes the conventional wiring device so that it penetrates the wiring device installation hole, first, the fixing plates provided on the upper and lower sides of the support are rotated horizontally.

Next, insert the support bar into the wiring device installation hole formed in the partition wall constructed on the inner side of the wall concrete.

Next, the worker inserts his or her finger into the inside of the support, erects each fixture vertically with the finger, then fastens the fastening screw to the screw hole formed in the fixture, moves the fixture, and fixes the support within the wiring fixture installation hole. It is ordered.

However, in the process of installing the support constituting the conventional wiring device configured as above inside the wiring device installation hole, the support member is inserted into the wiring device installation hole and then the worker inserts his or her finger into the inside of the support member and uses his or her finger to insert the support member into the wiring device installation hole. There was a problem with the installation of the support, which was inconvenient because each fixture that was lying horizontally on the support had to be erected vertically.

In addition, the conventional wiring device had the disadvantage that only one and two sheets of gypsum board were fixed because the range of movement within the frame in which the fixing plate was fixed was limited, so there was a limitation in that it could not be used for variable thicknesses of various thicknesses.
