Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a box for storing electrical equipment called a cubicle.

[0002]

2. Description of the Related Art A conventional box for storing electric equipment called a cubicle has a framework of a welding structure as shown in FIG. The assembling method is as follows. First, square frames 2 for the number of doors welded and assembled are set on the front and back of the square base 1 and bolted to each other, as shown in FIG. Bolt the vertical beam 3 between 2 and 2, and bolt the horizontal beam 4 and the waterproof plate 5 like
Then, the side plate 6 is bolted, and the roof 7 and the door 8 are attached last.

However, such a conventional box for accommodating electric equipment is welded when assembling the frame body 2 and has many problems such as the number of parts and the number of welded parts, so that the weight becomes heavy and the cost becomes high. there were. In addition, since a force is applied to a member to which the lifting bracket 9 required for this type of electric appliance storage box is fixed, the cross beam 4 is attached to the upper part of the frame 2 to increase the strength, but this also increases the weight. Was the cause.
In addition, the number of steps for bolting the waterproof plate 5 to the cross beam 4 was required.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned conventional problems and to provide a light-weight and low-cost box for housing electrical equipment with a reduced number of parts and welding points. .

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, a box for accommodating electric equipment according to the present invention comprises a back plate having an end portion bent to integrally form a rear pillar and two back plates. Equipped with a front pillar standing on a base, a vertical beam erected between the upper end of the rear pillar and the front pillar, and a horizontal beam erected between the front pillars and fixed with bolts. It is. In addition, it is preferable to adopt a structure in which the lifting bracket is attached to the upper end side surface of the rear pillar and the upper end side surface of the front pillar,
In addition, it is preferable that a drainer is integrally formed on the cross beam and a drainer is also integrally formed on the front pillar.

[0006] The electric appliance storage box of the present invention has a structure in which the rear pillar is integrally formed by bending the end of the back plate and the whole frame is fixed by bolts. It is not necessary to assemble, the number of parts is reduced, and the weight and cost can be reduced. Claim 2
If the lifting bracket is attached to the upper end side surface of the rear pillar and the upper end side surface of the front pillar as described above, the strength of the cross beam is not required even without the frame, so that the weight can be further reduced. In addition, if the drainer is integrally formed on the cross beam and the front pillar as in claim 3, the number of parts can be further reduced.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below. FIG. 1 is a perspective view showing a framework structure according to an embodiment of the present invention, FIG. 2 is a front view, and FIG. 3 is a right side view. FIG. 4
Is a horizontal sectional view, and FIG. 5 is a perspective view of a corner portion. In this embodiment, an electric appliance storage box having two doors is shown.

As shown in FIG. 4, in the present invention, the rear plate 12 is integrally formed by bending the end of the metal plate constituting the back plate 11. In this embodiment, two back plates 11 integrally formed with rear pillars 12 on opposite sides are erected on the rear side of a square base 13.

Reference numeral 14 denotes two independent front pillars,
Each of them is erected on both sides of the front side of the base 13. Further, an intermediate column 15 is erected at the center of the front side of the base 13. Door 1
In the case of a single sheet, the intermediate pillar 15 is unnecessary. It is preferable that a water drain 16 having a U-shaped cross section is integrally formed at the ends of the front pillar 14 and the intermediate pillar 15 by bending.

The rear plate 11, the front pillars 14, and the intermediate pillars 15 in which the rear pillars 12 are integrally formed are erected on the base 13 and fixed with bolts.
The vertical beam 17 is installed between the upper ends of the rear plate 4 and the intermediate column 15. Both ends are fixed with bolts. In this embodiment, one intermediate pillar 15 is used because two doors are used. However, two intermediate pillars 15 are used for three doors.

Next, a cross beam 18 is erected between the front columns 14, 14, and is also fixed with bolts. Since the cross beam 18 does not require strength, it may be lightweight. The lower part of the front surface of the cross beam 18 is bent to integrally form a drainer 19 having a U-shaped cross section. The end of the drain 19 of the cross beam 18 coincides with the vertical drain 16 formed on the front pillar 14 and the intermediate pillar 15, and rainwater or the like flows from the drain 19 into the drain 16. .

After the frame is formed by bolting in this way, as shown in FIGS. 2 and 3, the side plate 21, the door 2
2. By attaching the roof 23 and the like, it becomes a box for electric appliance storage.
Further, as shown in FIG. 5, a lifting bracket 20 is attached to the upper end side surface of the rear column 12 and the upper end side surface of the front column 14 to complete the product. As described above, the lifting bracket 20 is attached to the upper end side surface of the rear pillar 12 and the front pillar 14, and the horizontal beam is further attached to the upper portion of the frame body to increase the strength as compared with the conventional case where the lifting bracket is attached to the horizontal beam 18. It is not necessary to obtain it, and the weight can be reduced. In addition, as shown in FIG.
0 has different heights.

The electric appliance housing box according to the present invention thus constructed is different from the conventional one in which a frame is assembled by welding, and the rear column 1 is formed by bending the end of the back plate 11.
Since the skeleton has a structure in which the entire skeleton is fixed by bolts using components integrally formed with the components 2, the number of components is reduced and the number of welding points is reduced as compared with the related art. Therefore, it is possible to significantly reduce the weight and cost.

Further, by changing the mounting position of the lifting bracket 20, the strength of the cross beam 18 is not required, and the weight can be further reduced. Furthermore, cross beam 18 and front pillar 1
If the drainers 19 and 16 are integrally formed on the crosspiece 4, it is not necessary to weld the waterproof plate 5 to the cross beam 4 as in the related art, and it is possible to further reduce the number of parts and reduce the weight.

[0015]

As described above, the box for storing electrical equipment according to the present invention has a reduced number of parts and welded parts as compared with the conventional one by improving the frame structure, the mounting bracket, the mounting method of the drainer, and the like. It has succeeded in significantly reducing the weight and cost.
