Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an electrical equipment storage box equipped with a removable roof.

(Prior art) As shown in Fig. 2, a conventional electric equipment storage box with a roof has a front cover attached to the front opening.
Above the box body 21, which is tightened and fixed with cover bolts screwed into the corners, there is a roof 20 in which a metal plate is pressed into a U-shaped cross section and the side plates 3, 3 are provided downward from both sides of the top plate. Screw hole 2 provided in the box body 21
It was attached using a screw 23 that was screwed into 2.

(Problem to be Solved by the Invention) However, such an electrical equipment storage box requires screw holes 22 for roof attachment to be provided through the box body 21, which not only requires time and effort for processing;
This results in a disadvantage that the airtightness of the box body 21 is impaired due to the screw holes 22 provided through the through hole, so there is a need for an electrical equipment storage box in which the roof can be accurately and easily attached without any processing to the box body 21. was.

(Means for Solving the Problems) The present invention was completed in order to solve the above-mentioned problems, and consists of a box body in which a front cover is secured to the front opening by tightening cover bolts screwed into the four corners of the front cover. In an electrical equipment storage box with a roof attached above 12, in which the side plates are provided downward from both sides of the top plate, the engagement plate having the engagement portion with the cover bolt faces inward from the front end of the mounting plate. Attach the L-shaped roof fixing metal fittings stretched to the inner surface of each of the side panels with the mounting plate portions, and engage the engaging portions of the respective engaging plate portions with the cover bolts to attach the roof to the box body. It is characterized by being installed above the.

(Example) Next, the present invention will be explained in detail with reference to illustrated examples.

Reference numeral 1 denotes a roof in which an aluminum alloy plate is pressed and side plate parts 3, 3 are provided downwardly on both sides of a top plate part via folding lines 2, 2, and the front inner surface of each side plate part 3 of the roof 1 is Roof fixing fittings 4 are attached to each of them. The roof fixing metal fitting 4 has an engaging plate part 5 having a cutout-shaped engaging part with a cover bolt, and extends inward from the front end of the mounting plate part 6.
shape, and each roof fixing metal fitting 4 is attached to the mounting plate part 6.
is attached to the inner surface of each side plate part 3, and is attached using a screw 8 inserted into a screw insertion hole 7 formed in the side plate part 3. Reference numeral 12 denotes a box body for an electrical equipment storage box, and the box body 12 has an opening at the front, and a front cover 13 is secured to the front opening by tightening cover bolts 14 screwed into the four corners of the box body 12. The front cover 13 is formed with an operating section to which a push button switch 15 and an indicator light 16 are attached. The roof 1 equipped with the roof fixing fittings 4 as described above has an engaging portion on the shaft portion of the cover bolt 14 that tightens and fixes the engaging plate portion 5 to the front cover 13 of the box body 12. It is mounted above the box body 12 by engaging the cover bolts 14 and sandwiching them between the seat surface of the cover bolts 14 and the surface of the front cover 13.
In addition, 9 and 9 are other screw insertion holes provided below the screw insertion holes 7 provided in the side plate part 3 in order to change the mounting position of the roof fixing metal fittings 4 to below the side plate part 3,
When attaching the roof main body 1 above the box body 12 using this screw insertion hole 9, the box body 12 and the roof main body 1
A gap is formed between the two, which has the advantage of improving ventilation.

(Function) This structure has one roof and one box body, similar to the conventional electrical equipment storage box with a roof of this type.
The roof 1 is used in a state where rainwater is prevented from falling on the roof 1.The roof 1 is used by attaching the engaging plate portions 5 of the roof fixing fittings 4 provided on the front inner surface of the side plate portions 3 to the upper both sides of the box body 2. The front cover 13 is attached above the box body 12 by engaging with the bolt shaft portion between the front cover 13 and the bolt bearing surface of the cover bolts 14, 14 that are tightening and fixing the front cover 13 to the box body 12. Therefore, the roof 1 can be easily attached and detached by loosely tightening the cover bolts 14.
and tighten the engaging plate part 5 to the bolt seat surface and the cover 13.
If the roof 1 is firmly held between the box 12 and the
2 to block rainwater and direct sunlight from hitting operating parts such as a push button switch 15 attached to a front cover 13. Note that if the engagement plate portion 5 is not formed in the notch shape as in the embodiment but is formed in a circular hole, the cover bolts 14 must be completely removed from the front cover 13 before installation.

(Effects of the invention) As is clear from the above description, the present invention allows the roof to be attached to the electrical equipment storage box without any processing such as drilling screw holes through the box body.
The electrical equipment storage box can be used indoors or outdoors without any risk of compromising its airtightness, and it is also safe to use when installing electrical equipment in the electrical equipment storage box or for storing electrical equipment. When the cover is removed for maintenance and inspection, the roof is also removed at the same time, which has the advantage that the tip of the roof does not protrude above the front opening of the box, making the work easier.

Therefore, the present invention has great practical value as it eliminates the problems of the conventional electrical equipment storage box with a roof.
