Description

[Detailed Description of the Invention] The present invention relates to an improvement of a box for storing electrical equipment that can be used both indoors and outdoors.

Conventional electric equipment storage boxes for both indoor and outdoor use are box-shaped by welding side plates to each side edge of a rectangular back plate made of metal plate material.
Welding requires a lot of time, and finishing of the weld marks requires a lot of work, which increases costs.In addition, if the weld is long, welding distortion occurs, making it difficult for the opening/closing door to fit properly into the front opening. There was a problem in that many defective products were produced because they did not adhere tightly to the surface and rainwater penetrated inside.

The present invention was completed with the aim of creating a box for storing electrical equipment that solved the above problems. , 3 and a lower side plate 4 are connected to each other, the upper opening 6 of a horizontally long box material 5 is closed with an upper side plate 7, and only the upper side plate 7 faces downward from its rear edge along the back surface of the back plate 1. This is characterized in that a short eave plate part 8 which is bent and formed is partially fixed to the back plate 1 with spot welds 9.

A device configured in this way can be used indoors or outdoors by having an opening/closing door pivotally attached to the front opening and installing electrical equipment inside, but the present invention is suitable for storing electrical equipment. The box body includes a box material 5 in which left and right side plates 2, 3 and a lower side plate 4 are connected to a rectangular back plate 1 made of metal plate material by welding or bending, and a short eave plate portion 8 is directed downward from the rear edge. and an upper side plate 7 for closing the upper opening 6 of the box material 5 which is bent and formed, and this upper side plate 7 connects the short eaves plate part 8 to the upper rear surface of the back plate 1. In addition, since it is partially fixed to the back plate 1 with a plurality of spot welds 9, even when the box material 5 is horizontally long, the reinforcing effect of the short eave plate part 8 is maintained. Due to the reduction in welding area, there is almost no distortion of the box body, the opening/closing door is brought into close contact with the front opening edge of the box material, and rainwater from between the upper edge of the back plate 1 and the upper side plate 7 is prevented. The intrusion of rainwater is properly prevented by attaching the bent short eave plate part 8 to the back of the back plate 1, and the occurrence of defective products that may be caused by rainwater infiltration is almost eliminated. Yield is significantly improved. Moreover, since the upper side plate 7 is attached to the back plate 1 by means of a plurality of spot welds 9 formed by means such as spot welding, the time and labor required for welding work are reduced, and the finish of the weld marks is improved. It also has the advantage of reducing costs since no processing is required. In the above embodiment, the joints between the edges of the upper side plate 7 and the upper edges of the left and right side plates 2 and 3 are serially welded to eliminate gaps. A short eave plate part is provided along the outer surface of the upper part of the side plates 2 and 3, and this short eave plate part is also partially fixed to the outer surface of the box material 5 with a spot welded part like the short eave plate part 8. Of course, it is possible.

Therefore, the present invention has great practical value as it solves the problems of the conventional boxes for storing electrical equipment of this type.

Claims (1)

[Scope of utility model registration request] The upper opening 6 of a horizontally long box material 5, which is made up of a rectangular back plate 1 made of metal plate material, with left and right side plates 2, 3, and a lower side plate 4 arranged in series, is closed with an upper side plate 7, and only the upper side plate 7 is closed. An electrical device characterized in that a short eave plate portion 8 bent downward from its rear edge along the back surface of the back plate 1 is partially fixed to the back plate 1 with spot welds 9. Storage box.
