Description

[Detailed description of the invention] This invention relates to a switch box that is buried in a wall or the like to which switches, outlets, etc. are attached.In particular, mounting bolts are provided at the top and bottom centers of the box for attaching a support plate equipped with switches, outlets, etc. to the box. It has a structure that allows it to be temporarily fixed horizontally in the groove of the mounting seat, making it easier to use, and also blocking the screw hole of the mounting seat with the mounting bolt to prevent foreign matter such as dust and dirt from entering, which is convenient for implementation. That is.

Conventionally, it is known that a concave part for supporting a mounting bolt is integrally formed on the floor surface of a box, etc., but it is difficult to attach and detach the bolt, and it is also very difficult to form. Also, put tape on the screw hole of the mounting seat to remove dust.
Although it prevents the intrusion of earth and sand, it has the drawback of extremely poor workability, such as the need to remove the tape during installation.

This invention eliminates the drawbacks of the conventional method.The box has a mounting seat with a screw hole for screwing the mounting bolt in the upper and lower center of the box, and the mounting bolt is fitted into the mouth of the mounting seat. The present invention relates to a switch box in which a concave groove is bored in the horizontal direction, and a mounting bolt is removably fitted in the horizontal direction by utilizing the elasticity of the concave groove to provide temporary support and to close a screw hole.

An embodiment of this invention will be described below based on the drawings.

In the drawings, reference numeral 1 denotes a rectangular box with an open front side, which is made of, for example, a resin material.

Reference numerals 2 and 2' denote mounting seats integrally formed in the center of the upper and lower inner surfaces of the box 1, and there is a screw hole 5 into which a mounting bolt 3 and 3' can be screwed.
, 5'.

Reference numerals 4 and 4' denote grooves cut horizontally in the center of the openings of the mounting seats 2 and 2', and the mounting bolts 3 and 3' can be easily attached and detached horizontally using the elasticity of the grooves. , and is designed to prevent it from falling off unnecessarily after being fitted.

That is, the grooves 4, 4' match the outer diameter of the bolt 3.3', and the bolt 3.3' closes the screw holes 5, 5'.

In the figure, reference numerals 6 and 6' designate mounting legs provided on one side wall of the box 1, 7 a temporary fixing leg, 8 and 8' mounting legs, and 9 a punched hole.

In the above structure, when the mounting bolts 3.3' are fitted and supported sideways into the grooves 4, 4' of the mounting seats 2, 2', the bolts 3.3' are firmly held and do not fall off unnecessarily. Never.

Therefore, the bolts will not fall out and be lost during storage, transportation, or other handling of the box.

Also, attach the mounting bolts 3.3' to their insertion holes 5, 5'.
This prevents dust, dirt, etc. from entering the screw hole during handling.

Furthermore, when using Bolt 3.3',
, 3' are located at the open end of the box 1, so that they can be easily removed.

According to this invention explained above, the switch box is fixed to a wall pillar, crosspiece, etc. with the mounting bolts fitted into the grooves at the mouths of the screw holes of the mounting seat and the screw holes closed.
To prevent foreign matter such as wall soil and dust from entering a screw hole and clogging it during wall construction, and to prevent a mounting bolt from becoming impossible to screw in.

In other words, when installing the switch mounting board between the mounting seats of the switch box after wall construction, remove the mounting bolt from the groove, open the mouth of the screw hole, align the mounting hole on the board with the screw hole, and screw the mounting bolt. Therefore, the mounting bolts can be screwed together reliably and easily, workability can be improved, and there is great practicality in actual use.
