Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a box for storing electrical equipment having hanging bolts.

[0002]

2. Description of the Related Art A heavy electrical equipment housing box needs to be provided with hanging bolts on the upper surface of the box body for hanging and moving with a crane or the like. Conventionally, as shown in FIG.
Is provided with a suspension bolt 22 and a suspension bolt insertion hole 23 for attaching the suspension bolt 22.

[0003] box body 2 places hanger bolt insertion holes 23 in the vicinity of the right and left ends of the front and rear direction of the intermediate portion of the upper surface 21 is provided, hanging from the box top 21 to the hanging bolt insertion hole 23 bolt 2
2 and then tightened and fixed from the inside of the box with the flat washer 24 and the suspension bolt tightening nut 25.

[0004]

However, after the electric device storage box is installed, the suspension bolts 22 become unnecessary.
If the hanging bolts 22 are left attached, there is a disadvantage that the appearance is impaired. Therefore, the hanging bolts 22 are removed from the upper surface 21 of the box body, and the hanging bolt insertion holes 23 are covered with special parts. It is necessary to use dedicated parts to cover the parts.
However, there is a disadvantage that the production cost is increased . Also,
Since the electrical equipment housing box was not provided with an entrance / exit line port, there was a drawback in that it took time to open the entrance / exit line port.

[0005]

Means for Solving the Problems The conventional electric equipment storage described above.
The purpose of the present invention is to remove the suspension bolts
When detached, hanging bolts can be easily used without using dedicated parts
The insertion hole can be covered, which can also impair the beauty
Installation and installation of entrance / exit lines can be omitted.
A box for storing electrical equipment that can reduce the work time for
At least a rectangular entry and exit on the top of the box
A line opening, a covering plate covering the input / output line opening,
A suspension bolt insertion hole is provided in front of the entrance / exit line opening, and the suspension bolt
And a suspension bolt which is detachably attached to the insertion hole.
Electrical equipment storage box, the longitudinal direction of the cover plate
The width dimension of the front is different from that of the rear,
The hanging bolt insertion hole is exposed by inverting the rear.
That is, it is formed so as to be able to change the outflow and coating.

[0006]

[Function] A state in which a suspension bolt is attached to the suspension bolt insertion hole
In this state, the side with the shorter width in the longitudinal direction of the cover plate is
And attach it. At this time, the width of the covering plate is
Hanging bolt insertion hole is exposed because it is shorter than the interval between insertion holes
I do. On the other hand, a suspension bolt is inserted into the suspension bolt insertion hole.
When not attached, the longitudinal width of the cover plate is long.
With the other side facing the front. At this time, the width of the covering plate
Method is longer than the interval between the suspension bolt insertion holes,
The insertion hole is covered with a cover plate.

[0007]

1 to 3 show an embodiment of a box for storing electric equipment according to the present invention. Hereinafter, description will be given based on these drawings.

[0008] Electrical device-accommodating box body, covering the input and line opening 2 of substantially length <br/> square-shaped in a box body upper surface 1, the input and line opening 2
Cover plate 5 to be inserted and hanging bolts inserted in front of the input / output line opening 2.
Removably attached to through hole 3 and hanging bolt insertion hole 3
And a suspension bolt 6 . The covering plate 5 has a width in the longitudinal direction.
The law is formed so that the front and back are different and the hanging bolt
A substantially convex shape having an insertion hole covering portion 4 that covers the insertion hole 3
It is formed. A hanging bolt 6 is detachably attached, and a stud bolt 7 is welded to the cover plate 5 so as to cover the input / output line opening 2 from the upper surface 1 of the box body and to be attachable thereto. Are provided, and stud bolt insertion holes 8 provided so as to cover the input / output line opening 2 are provided.
Tighten and fix.

Further, a suspension bolt 6 is inserted into the suspension bolt insertion hole 3 on the upper surface 1 of the box body, and is tightened and fixed from the inside of the box body 9 by a flat washer 11 and a suspension bolt tightening nut 12.

FIG. 2 is a top view of the box for storing electric equipment in FIG. 1 with hanging bolts attached thereto, and FIG.
Electrical equipment hanging bolt accommodating box member is a top view of a state in which no attached, hanging bolts 6 are two positions in the vicinity of the right and left ends of the front and rear direction of the intermediate portion A of the box on <br/> surface 1 in provided, and out line opening 2 is substantially rectangular, longitudinal direction of the intermediate portion B of the input and line opening 2 before the middle portion a of the box top 1
In FIG. 2, only the input / output line opening 2 is attached to the cover plate 5 with the insertion hole covering portion 4 facing the direction in which the input / output line opening 2 is displaced. On the other hand, FIG. 3 reverses the direction of the insertion hole covering portion 4 of the covering plate 5 to the direction opposite to that of FIG. 2 to cover the input / output line opening 2 and the suspension bolt insertion hole 3,
Attached.

The hanging bolt 6 is inserted into the hanging bolt insertion hole 3.
In the attached state, the side where the width in the longitudinal direction of the cover plate 5 is shorter
To the front side. At this time, the width dimension of the cover plate 5
Is shorter than the space between the suspension bolt insertion holes 3,
The insertion hole 3 is exposed. On the other hand, the suspension bolt insertion hole 3
When the suspension bolts 6 are not attached to the
With the long side in the longitudinal direction
You. At this time, the width dimension of the cover plate 5 is
Since it is longer than the interval, the suspension bolt insertion holes 3
More covered.

In the above embodiment, the input / output line opening 2 is used.
Is formed in a rectangular shape, and the cover plate 5 is formed in a convex shape. However, this is an example, and the shapes of the input / output line opening 2 and the cover plate 5 are not limited thereto. It can be changed as appropriate without departing from the spirit.

[0013]

[Effects of the Invention] As described above, the box for storing electrical equipment according to the present invention has a substantially rectangular input / output line at least on the upper surface of the box.
An opening, a covering plate for covering the entrance / exit line opening,
A suspension bolt insertion hole in front of the wire opening;
In a box for storing electrical equipment , comprising: a suspension bolt detachably attached to a through hole ; a longitudinal width of the cover plate;
Dimensions are made different between front and back, front and back
The hanging bolt insertion hole is exposed by reversing
The hanging bolts can be removed
When removed, easily insert hanging bolts without using dedicated parts
The through-hole can be covered, and the appearance is not impaired.
And the need to open the entrance / exit lines can be saved.
Work time can be shortened .
