Abstract

PROBLEM TO BE SOLVED: To facilitate coupling a lid with protrusions to avoid deviating in any direction from an opening by forming coupling holes into the lid to couple it with the protrusions and mounting the lid on a box with the coupling holes facing at the protrusions. SOLUTION: Conical protrusions 9 are mounted on the end face 8 of a side face opening 6. To mount a side face plate 7 on a box 1, holes 10 are formed positions of the plate 7 facing at the protrusions 9. When the plate 7 is mounted in the opening 6 of the box 1, the holes 10 of the plate 7 are hooked on the protrusions 9 of the end face 8 of the opening 6 to position it, thereby easily coupling the lid with the protrusions and avoiding deviating it in any direction from the opening.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of an electric equipment housing box for housing various electric equipment.

[0002]

2. Description of the Related Art As shown in FIGS. 2 and 3, the structure of a conventional electrical equipment housing box is an electrical equipment housing box 31.
When the opening portion 33 is provided on the side surface 32 of the and the lid 34 is used to apply the lid, the hook metal fitting 35 welded to the lid 34 is provided.
Is hooked on the end 36 of the opening 33, and the protrusion 38 provided on the handle 37 is used to cover the opening 3 with the lid 34.
3 was covered.

Alternatively, as shown in FIGS. 4 and 5, the lid 4
0 is provided with a hole 41, the box body 42 is tapped, the hole 41 of the lid body 40 and the tap 43 of the box body body 42 are opposed to each other, a screw 44 is inserted, and the lid body 40 is opened. It was fixed.

[0004]

However, according to the conventional technique of hooking the hooking metal 35 on the end 36 of the opening 33, as shown in FIGS. There is a drawback that the protrusion 38 interlocked with is difficult to engage with the box body.

When the lid 40 is screwed to the box body 42 as shown in FIGS. 4 and 5, it is difficult to align the hole 41 of the lid 40 with the tap 43 of the box body 42 and the screw 44. The workability was poor.

[0006]

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a box for storing electrical equipment, which has a simple structure and can be easily attached, and which has an opening covered with a cover.
The structure is such that an opening is provided on a side surface or a back surface and a projection is provided on an end surface of the opening in order to cover the opening with a lid, and the projection can be engaged with the lid. A fitting hole is provided, and the lid body is attached to the box body with the engagement hole of the lid body facing the projection body.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION In many cases, an electric equipment housing box for housing electric equipment such as office automation equipment and measuring instruments has a side surface or a back surface opened. The opening is covered with a side plate or a back plate. A conical projection is provided on the end face of the opening of the box body, and the hole provided in the side plate or the back plate is engaged with the projection to position it. Cover with.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the structure of a box for housing electric equipment according to the present invention will be described with reference to the accompanying drawings.

A box for storing electric equipment according to the present invention is shown in FIG.
As shown in FIG. 3, an opening 4 is provided on the front surface 2 of the box body 1 and is covered with a door body 3 that can be rotated by a hinge. The side surface 5 of the box body 1 is also opened.

The side opening 6 is covered by a side plate 7, and a conical projection 9 is attached to the end face 8 of the side opening 6. When the side surface plate 7 is attached to the side surface opening 6 of the box body 1, a hole 10 is provided at a position where the protrusions 9 of the side surface plate 7 face each other. When the side plate 7 is attached to the side opening 6 of the box body 1 in the vicinity of the hole 10,
A cushioning material 11 is attached so that the box body 1 is not damaged. A handle 12 is attached to the side surface plate 7 for attaching and detaching the side surface plate 7, and a stopper portion 13 for locking the side surface plate 7 in the side surface opening 6 is provided.

The box for storing electrical equipment according to the present invention has an O
Electrical equipment such as A equipment and measuring instruments are stored, and the side surface of the box body 1 is opened for maintenance and inspection of these electrical equipment.
The side surface plate 7 covers the side surface opening 6. The side plate 7 is the door body 3
Unlike, you rarely use hinges. When the side plate 7 is attached to the side opening 6 of the box body 1, the side plate 7 is attached to the protrusion 9 provided on the end face 8 of the side opening 6.
The hole 10 provided in the is hooked for positioning.
Then, the stopper 13 is locked to the end of the side surface opening 6 of the box body 1, and the side plate 7 is attached to the box body 1.

The shape of the projection 9 is not limited to the conical shape of this embodiment, and can be changed as appropriate without departing from the gist of the present invention. Further, the opening provided in the box body is not limited to the above-mentioned side surface, and can be changed as appropriate without departing from the gist of the present invention. For example,
Even when an opening is provided on the back of the box body, as in the case of the side surface, the opening is covered with a back plate, a projection is provided on the end face of the opening, and the back plate is hooked on this projection. Attach the back plate to the box body.

[0013]

As described above, in the box for storing electrical equipment according to the present invention, the box body is provided with the protrusions, and
Since the lid has an engaging hole into which the protrusion can be engaged, and the engaging hole of the lid is opposed to the protrusion to attach the lid to the box body, the lid is inserted into the protrusion. It is easy and the lid does not shift back and forth and left and right with respect to the opening, so that workability can be improved.
