Description

[Detailed Description of the Invention] The present invention relates to metal boxes such as distribution boxes and operation panels.

Conventionally, this type of box is made by bending a single metal plate and welding its corners, or by separately pressing left and right and top and bottom side plates and welding them together.

Therefore, transportation is expensive, space is a problem when it comes to inventory, and there are also problems with packaging.

The present invention has been made in view of the above points, namely, horizontal grooves and vertical grooves are formed on the front and rear ends of the left and right and upper and lower side plates, and the upper and lower and left and right ends are cut off at approximately 45 degrees so that they can be connected to each other. The left and right and top and bottom side plates are fixed to each other using screws that abut each other, insert the frame frame into the horizontal groove at the front edge, insert the back plate into the horizontal groove at the rear edge, and insert the back plate and frame frame into the vertical grooves of the left and right and top and bottom side plates. death,
Doors are screwed onto the front surfaces of the left and right and top and bottom side plates, which eliminates the need to weld the box into shape, making it easy to transport and effective for inventory, packaging, etc. The purpose is to eliminate the need for special tools for assembly.

The present invention will be explained below based on drawings showing one embodiment of the invention. X is a metal box body;
The lower box 1 and front door 2 are connected. Reference numeral 3 denotes a metal back plate constituting the lower box 1, which faces the wall H side. Reference numeral 4 denotes left and right side plates, each of which has a horizontal groove 6 extending vertically at its front and rear ends, and its upper and lower ends 4a are cut off at approximately 45 degrees. Reference numeral 5 designates upper and lower side plates, each of which has a horizontal groove 6 continuous with the horizontal groove 6 of the left and right side plates 4 at its front and rear ends, and the left and right ends 5a are cut off at approximately 45 degrees.
The upper and lower ends 4a of the left and right side plates 4 are brought into contact with each other.
Horizontal grooves 6 at the rear ends of the left and right and upper and lower side plates 4 and 5
The back plate 3 is inserted into the frame frame 7, and the frame frame 7 is inserted into the horizontal grooves 6 at the front ends of the left and right and upper and lower side plates 4 and 5. Furthermore, the ends 4a, 5 of these left and right and upper and lower side plates 4, 5
The joining of a is as in the embodiments shown in FIGS. 1 to 4,
Located inside the horizontal groove 6, its opening is the horizontal groove 6
Vertical grooves 8 that are substantially perpendicular to the openings are provided at the front and rear ends of the left and right and upper and lower side plates 4 and 5, and tapping screws 9 that pass through the back plate 3 and the frame frame 7 are screwed into the vertical grooves 8. The left and right and upper and lower side plates 4 and 5 are fixed by interposing them, and if necessary, they may be fixed by using triangular corners 10 as shown in FIG. Reference numeral 11 is a hinge fitting, and the left and right and upper and lower side plates 4,
5 and the front door 2, and the door 2 is rotatably screwed. In addition, in the embodiment, the hinge fitting 11 is
A part of the hinge is attached to one of the left and right and upper and lower side plates 4 and 5, and the rest is attached to the front door 2, and a pivot pin is attached at the assembly site. It is also possible to attach the entire assembly to one of the left and right and upper and lower side plates 4 and 5 or the front door 2 in advance, and screw the hinge fitting 11 to the other side at the assembly site.

As described above, the present invention forms horizontal grooves 6 and vertical grooves 8 at the front and rear ends of the left and right and upper and lower side plates 4 and 5, and cuts off the upper and lower left and right ends 4a and 5a at approximately 45 degrees so that they abut each other, and the front ends are horizontal. Insert the frame frame 7 into the groove 6, insert the back plate 3 into the horizontal groove 6 at the rear end, and insert the left and right and upper and lower side plates 4,
The left and right and upper and lower side plates 4 and 5 are fixed to each other by screws 9 that are screwed into the vertical grooves 8 of 5 through the back plate 3 and the frame frame 7, and the door 2 is hinged at the front side of the upper and lower side plates 4 and 5. Therefore, no welding is required to make the mold of the box body 1, and the box can be transported, inventory managed, and packaged flatly without being molded. It is also effective for packaging, etc., and no special tools are required for assembly.
