Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a louver attached to ventilate a box for storing electrical equipment such as a distribution box that requires heat radiation, and relates to a hood structure for preventing rainwater from entering the louver when used outdoors. .

[0002]

[Prior art]

 Conventionally, a louver was attached to the side of the box in order to ventilate a box for storing electrical equipment such as a heat generating control device such as an inverter or a sequencer or a ballast or transformer of a lighting fixture for discharge. In order to use this electric device storage box outdoors, a hood covering the louver was necessary to prevent rainwater and the like from entering.

That is, as shown in FIGS. 2 and 3, a rectangular mounting hole 12 is provided on the side surface of the electrical equipment housing box 1, and a rectangular louver 14 is inserted from an opening 13 a at the bottom of the hood 13. Then, the peripheral edge portion 14a is overlapped so as to cover the opening portion 13b on the back surface of the hood 13, and this state is maintained to overlap the rectangular mounting hole 12. Then, a screw insertion opening 12 'provided near the corner of the square mounting hole 12, a screw insertion opening 13' provided near the corner of the opening 13b on the back surface of the hood, and a corner of the square louver 14 near the corner. The screw 5 was inserted from the inside of the box body so as to be inserted into any of the screw insertion ports 14 'provided in the above, and was fixed by tightening.

As another means, as shown in FIGS. 4 and 5, a circular mounting hole 22 is provided on the side surface of the electrical equipment housing box 1, and a circular shape is formed from an opening 23 a on the bottom surface of the hood 23. The louver 24 is inserted, the peripheral edge portion 24a is inserted into the opening portion 23b on the back surface of the hood 23, and this state is maintained, and the circular attachment hole 22 is inserted. The round louver fixing body 26 was screwed onto the peripheral edge 24a. The peripheral portion 24a of the round louver 24 and the round louver fixing body 26 have a male screw and a female screw, and they are screwed and fixed to each other.

[0005]

[Problems to be solved by the device]

 In such a louver hood, the shape of the opening on the back of the hood differs between the square louver and the round louver. Had to prepare a hood for each round louver. In addition, packing must be prepared in both square and round shapes, which has the drawback of complicating parts management and increasing costs.

[0006]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the louver hood in the electrical equipment housing box of the present invention has a rear hood having an opening formed in a substantially square shape that fits a rectangular louver, and each side of the hood. The approximately middle part is formed in an approximately arc shape that fits the round louver, and can be attached to both the square louver and the round louver.

[0007]

[Action]

 A louver for ventilation can be easily formed by mounting the louver by sandwiching the plate and the hood of the electrical equipment storage box.

[0008]

【Example】

 Hereinafter, an embodiment of a louver hood in a box for storing an electric device according to the present invention will be described with reference to the accompanying drawings.

In FIG. 1, a hood 3 attached to a box 1 for housing electrical equipment has an opening 3a on the bottom surface and an opening 3b on the back surface. The shape of the opening 3 b on the back surface is formed in a substantially quadrangular shape that fits the rectangular louver 14, and the substantially middle portion of each side is formed in a substantially arc shape that fits the round louver 24.

When the square louver 14 is attached to the electrical equipment storage box 1, a square attachment hole 12 is provided on a side surface of the electrical equipment storage 1, and the square louver 14 is inserted from the opening 3 a on the bottom surface of the hood 3. The louver 14 is inserted, and its peripheral portion is overlapped so as to cover the opening 3b on the back surface of the hood 3, and while maintaining this state, the louver 14 is overlapped so as to cover the rectangular mounting hole 12. Then, a screw insertion opening 12 ′ provided near the corner of the square mounting hole 12, a screw insertion opening 3 ′ provided near the corner of the opening 3b on the back surface of the hood, and the square louver 14 are provided. The screw 5 is inserted from the inside of the box so as to be inserted into any of the screw insertion openings 14 'provided near the corners, and is fixed by tightening. In this case, since the corners of each side of the opening 3b on the back surface of the hood 3 are covered by the corners of the rectangular louver and the mounting holes 12 of the rectangular shape, they are not opened. On the other hand, the substantially arcuate portion of each side is covered with the peripheral edge of the rectangular louver 14 and is provided with a packing (not shown), so that it does not become an opening.

In addition, when the round louver 24 is attached to the electrical equipment housing box 1, a round mounting hole 22 is provided on the side surface of the electrical equipment housing 1, and the opening 3 a on the bottom surface of the hood 3 is used. The round louver 24 is inserted, the peripheral edge portion 24a is inserted into the opening 3b on the back surface of the hood 3, and this state is maintained, and the round louver 24 is inserted. Then, the round louver fixing body 26 is screwed onto the peripheral portion 24a. The peripheral edge 24a of the round louver 24 and the round louver fixing body 26 have a male screw and a female screw, and are screwed and fixed to each other. In this case, the substantially arcuate portion of each side of the opening 3b on the back surface of the hood 3 is covered with the peripheral edge of the rectangular louver 14, and packing (not shown) is applied. It does not become an opening. Then, the peripheral edge 24a is inserted into the opening 23b on the back surface of the hood 23, and this state is maintained, and the circular attachment hole 22 is inserted. Then, the round louver fixing body 26 is screwed onto the peripheral edge portion 24a. The peripheral portion 24a of the round louver 24 and the round louver fixing body 26 have a male and female screw relationship, and were screwed together and fixed. In this case, since the corners of each side of the opening 3b on the back surface of the hood 3 are covered with the rectangular mounting holes 11 and are provided with packing (not shown), no opening is formed. On the other hand, the portion where the substantially middle portion of each side is formed in a substantially arc shape is covered by the contact of the peripheral edge portion 24a of the round louver 24 and is provided with packing (not shown), so that it becomes an opening. There is no.

[0012]

[Effect of device]

 With the louver hood according to the present invention, the shape of the opening on the back of the hood is suitable for both square louvers and round louvers. It is not necessary to prepare a round louver hood for each type louver, and it is only necessary to prepare one type of packing common type, eliminating the need to prepare a square type and a round type. Therefore, there is an effect that parts management can be simplified and costs can be suppressed.
