Description

[Detailed description of the invention] This invention relates to the improvement of an outlet box for storing electrical outlets installed on the floor of a building, etc., and in particular, the height of the box itself can be easily adjusted using adjustable legs. The present invention also relates to connectable outlet boxes in which the box bodies can be connected near the corners using connecting plates.

Conventionally, outlet boxes buried under the floor had little means for adjusting the height, so if there was a difference in the installation depth of the outlet box, it was necessary to put stuffing under the box itself. There was a problem that adjustment work was time consuming. In addition, if the box bodies that accommodate outlets for different purposes, such as those for light electrical power and those for heavy electrical power, are constructed as independent units, there is a drawback that on-site work becomes complicated.

The present invention eliminates the disadvantages of the conventional outlet box described above, uses almost L-shaped adjustment legs and connecting plates, and allows the height of the box body to be easily adjusted. It is an object of the present invention to provide a connectable outlet box in which a large number of box bodies can be connected to each other as required.

To explain the present invention in detail, an approximately L-shaped adjustment leg, which is formed by connecting a horizontal piece to the lower end of a vertical piece with a long hole bored along its length, is attached to a rectangular or rectangular box. A connecting plate that is attached near the edge of the side plate of the main body so as to be slidable in the vertical direction so that the set screw is located in the elongated hole of the adjustment leg, and has notches at both ends into which the set screw can be inserted. This is a connectable outlet box, characterized in that the box bodies are connected to each other near the corner portions by using the box bodies.

EMBODIMENT OF THE INVENTION Hereinafter, the specific structure of this invention will be explained in detail based on the illustrated Example.

In the figure, 1 is a square or rectangular box body with side plates 3 erected on the four sides of a bottom plate 2, and a knockout hole 5 is provided in the side plate 3 of the box body 1 for attaching a conduit 4, etc. be. Also,
At a suitable position on the upper surface of the box body 1, a mounting member 6 having a screw hole for mounting a floor base or the like is provided to protrude inward of the housing.

Reference numeral 7 denotes an adjustment leg that is attached to the box body 1 near the edge of the side plate 3 using a set screw 8.

This adjustment leg 7 has a long hole 1 located approximately in the center in the longitudinal direction.
A set screw 8 screwed into the vicinity of the edge of the side plate 3 is connected to a long hole 10 of the adjustment leg 7. It is now located within. In addition,
Although it is possible to use only one set screw 8, it is better to attach two setscrews in the vertical direction of the side plate 3 so that the adjustment leg 7
stability is improved, and favorable results can be obtained. When this set screw 8 is loosened with a screwdriver or the like, the adjusting leg 7, which was clamped between the screw head and the side plate 3, becomes free and can slide vertically within the elongated hole 10. The support height of the main body 1 can be changed freely.

Reference numeral 12 in the figure is a connecting plate provided with notches 13, 13 at both ends into which the set screw 8 can be inserted, and after passing the shaft of the set screw 8 into the notches 13, 13, When tightened, the connecting plate 12 and the adjusting leg 7 are clamped between the side plate 3 of the box body 1 and the screw head of the locking screw 8, and the box bodies 1 can be connected to each other near the corners. be.

The adjustment legs 7 are installed near each corner of the box body 1, and the connection between the box bodies 1 using the connecting plate 12 is performed when the mounting surface of the conduit 4, etc. is connected as shown in FIG. By maintaining the opening at approximately 90 degrees, the connection work of the conduit 4 etc. can be carried out smoothly. In addition to the connection configuration shown in FIG. 3, it is of course possible to connect the side plates 3 in parallel by making them contact each other. Note that if the knockout holes 5 provided in the side plate 3 of the box body 1 are provided at different heights for each box body 1, collisions with the conduit pipes 4, etc. can be prevented, and wiring work can be carried out in an orderly manner. Become.

The outlet box of the present invention has the above-mentioned configuration, and when there are variations in the ground surface at the work site, the height can be adjusted by loosening the set screw 8 and sliding the adjusting leg 7 in the vertical direction.
For example, when wiring two or more types of wiring for different purposes, such as signal lines and power lines, the box bodies 1 can be connected and integrated using the connecting plate 12, making on-site work even more efficient. be.

As described above, according to the present invention, the height of the box body can be easily adjusted, and a large number of box bodies can be connected together as necessary, which is highly effective for wiring work on site. It is something.
