【Example】
Next, the present invention will be described in detail based on the illustrated embodiment.
Reference numeral 1 denotes a rectangular box for storing electrical equipment, and 2 is a flat metal holder that is attached to the upper and lower positions on both sides of the back of the box 1. In this metal fitting holder 2, a horizontal insertion port 21 and a vertical insertion port 22 serving as bar insertion ports are arranged adjacent to each other by changing the direction by 90 degrees, and a bolt insertion hole 23 is provided on the surface. The metal fitting holder 2 has a lateral insertion opening 21 close to both side edges of the box 1 and is sufficient to receive at least a protruding piece 31 of the bar 3 described later between the vertical insertion opening 22 and the upper and lower edges of the box 1. It is attached to the box 1 by welding the bent leg ends of the two sides where the horizontal insertion port 21 and the vertical insertion port 22 are not formed to the back of the box so as to leave a gap.
[0007]
On the other hand, the bar 3 to be inserted into each bracket holder 2 can be inserted into either the horizontal insertion port 21 or the vertical insertion port 22 and is formed with a screw hole 34 into which the bolt 4 is screwed. A protruding plate 32 provided with a mounting hole 35 at the tip of the insertion portion 31 is a bent plate that is continuously connected via a bending step portion 33 so that the surface thereof is positioned higher than the head of the bolt 4. The bar 3 can be freely rotated between the horizontal insertion port 21 and the vertical insertion port 22 around the bolt 4 when the bolt 4 is loosened, and the bolt 4 is tightened tightly. In some cases, the bolts 4 are fastened and fixed so as not to be able to rotate around the bolt 4. In order to simplify this work, in the embodiment, a gap between the horizontal insertion port 21 and the vertical insertion port 22 is used. A leg seat 24 for preventing slippage is located on the opening edge of Previously formed by pressing a. Then, when the bolt 4 is loosened, the bar 3 descends and can pass between the lateral insertion port 21 and the vertical insertion port 22 through the leg seat portion 24 around the bolt 4, and the bolt 4 When the is tightened, the bar 3 rises and comes into contact with the back surface of the bracket holder 2 so that the bar 3 cannot rotate.
[0008]
In the non-use state shown by a chain line in FIG. 1 in which the insertion portion 31 of the bar 3 is inserted into the vertical insertion port 22 of the metal fitting holder 2, the vertical insertion port 22 and the box 1 are configured as described above. Since there is sufficient space between the upper and lower edges of the bar 3 to receive the protruding pieces 32 of the bar 3, the protruding pieces 32 of the bar 3 may protrude from the upper and lower edges as well as the left and right edges of the box 1. The bar 3 can be accurately boxed in a small space, and the bar 3 has a protruding piece 32 at the tip of the insertion portion 31 and the surface of the bolt 4 screwed into the screw hole 34 of the bar 3 from the bolt insertion hole 23. Since the bent projections 33 are arranged so as to be positioned higher than the head, the flat plate-like projecting pieces 32 that are substantially parallel to the back of the box at the four back corners of the box 1 are provided in a plurality. It becomes the receiving surface when the box 1 is stacked, and the bending step Box 1 under elastic by 33 may be a can to be overlaid over the projecting pieces 32 of the four bar 3 box surface eliminate precisely that are damaged by fitting the holder 2 and the bolt 4.
[0009]
Thus, when the box 1 is temporarily installed on a wall of a building or a temporary enclosure at a construction site, when the bolt 4 is reversely rotated so as to release the tightening of the bolt 4, the bolt 4 is connected to the bolt 4 through the bolt insertion hole 23. Since the screwed bar 3 is lowered and reaches the position where the bar 3 can rotate between the horizontal insertion port 21 and the vertical insertion port 22 under the leg seat portion 24, the vertical insertion is performed in this state. If the protruding piece 32 of the bar 3 protruding from the insertion port 22 is pushed with a finger, the bolt 4 rotates about the bolt 4 toward the horizontal insertion port 21, so that the protruding piece 32 comes close to both side edges of the box 1. 1 and FIG. 2 projecting from the lateral insertion port 21 is tightened until the bar 3 is in contact with the back surface of the bracket holder 2 to fix the bar 3 to the bracket holder 2. After that, the box 1 is built using the mounting hole 35 near the tip of the overhanging piece 32. It is sufficient to accurately easily temporary against such temporary enclosure of the wall or construction site.
[0010]
【The invention's effect】
As is apparent from the above description, the present invention can prevent the protruding piece of the bar from protruding from the side edge of the box when not in use. When the boxes are stacked, the box-shaped projecting pieces, which are substantially parallel to the back of the box at the four corners of the back of the box, become the box receiving surface and accurately support the box under the elasticity of the bent stepped portion. It is convenient for transportation and storage, such as the bolt head and bracket holder are not damaged, and has the advantage that the structure is simple and inexpensive.
Also, as shown in the examples, if the bracket holder is formed with a leg seat portion for preventing slippage located between the horizontal insertion port and the vertical insertion port, the bar can be used when tightening the bolt. Since the rotation can be prevented, the position of the bar can be changed more easily.
Therefore, the present invention contributes to the development of the industry as a mounting device for an electrical equipment storage box that solves the conventional problems, and is extremely large.
