BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for temporarily fixing a frame of an electric device storage box comprising a box body, a frame and a door.

[0002]

2. Description of the Related Art Conventionally, an electric device housing box for housing various electric devices basically comprises a box body, a frame, and a door, and the frame is rotated around one side of the door as a support shaft. It had hinges that were movable, and was fixed to the box body and hinged on the door. In the electric device housing box configured as described above, in order to attach the frame to the box body, screw insertion holes are formed in the upper plate and the lower plate of the frame 21 as shown in FIGS. 22 are provided at two places, respectively, and the box body 23 is provided with two frame body mounting brackets 25 at the opening side peripheral edges 24 of the upper side plate and the lower side plate. A screw insertion hole 26 is provided at the center of the frame mounting bracket 25. Screw insertion hole 22 and screw insertion hole 26
Are formed at opposing positions. In order to attach the frame body 21 to the box body 23, the frame body 21 is placed so as to cover the frame body 21 from the opening surface direction of the box body 23, the screw insertion holes 22 and the screw insertion holes 26 are aligned, and both the screw The screw 27 was inserted through the insertion hole and fixed by tightening.

However, when attaching the frame 21 to the box body 23, the operator first supports the frame 21 with one hand, and fastens the frame 21 to the box body 23 with the other hand using screws 27. This has the disadvantage that both hands are closed and the mounting work is extremely difficult, and the work is dangerous. The work becomes even more difficult as the box for storing electrical equipment becomes larger,
It was difficult to work by one worker, and it was necessary to work by two or more workers.

[0004] In order to solve such a disadvantage, for example, Japanese Unexamined Utility Model Publication No. 4-114705 has been proposed.

When the frame is mounted on the box body, a rod-shaped temporary fixing jig 33 is mounted on the frame mounting bracket 32 on the upper side plate of the box body 31 as shown in FIG.
4 is an excellent one in which the temporary fixing jig 33 is inserted into the screw insertion hole 35, and the frame body 34 is temporarily fixed and attached.

[0006]

[Problem to be solved by the invention] However, FIG.
According to the above prior art, when the frame body 34 in the state where the door body 36 is closed and attached is temporarily fixed to the box body 31, the screw insertion hole 35 of the frame body 34 is not visible, so the jig for temporary fixing is used. If it is very difficult to position the frame body 33 with the screw insertion hole 35 and the door body 36 in a state where the door body 36 is opened and attached, the door body 3 is
6 is an unstable state, and thus has a drawback that the operation involves danger.

After temporarily fixing the frame 34, the frame 34
When the main body is permanently fixed to the box body 31, the screws must be inserted through the screw insertion holes 35 of the frame body 34 and screwed to the frame body mounting brackets 32 of the box body 31.
Had to be removed.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a structure for temporarily fixing a frame of a box for storing electric equipment, in which a single worker can safely and easily mount the frame.

[0009]

Means for Solving the Problems In order to solve the above-mentioned problem, a temporary fixing structure for a frame of a box for storing electric equipment according to the present invention comprises
The frame body is provided with a hook on the upper back surface, the support member is provided on the lower back surface, and the box body is provided with a receiving member facing the hook member.

The frame body mounting bracket of the box body and the receiving member provided on the frame body and opposed to the hooking member are integrally formed.

The inner or outer edge of the support is formed in a tapered shape, and the tapered inner or outer edge is brought into contact with the frame mounting bracket of the box body. , And the support is provided on the lower back surface of the frame.

[0012]

When the frame is attached to the box body, the inner edge or the outer edge of the tapered support is provided on the lower back surface of the frame, and the frame mounting bracket at the lower portion of the box body. After setting the mounting position of the frame by abutting on the supporting body, placing the supporting member on the periphery of the opening surface at the lower part of the box body and hooking it, the hook provided on the upper back surface of the frame body is attached to the box body. And a frame is temporarily fixed and attached. When the frame is removed from the box body, the frame can be removed from the box body by lifting the frame and pulling only the upper portion of the frame toward the user.
