BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a louver for an electric equipment cabinet that ventilates an electric equipment cabinet containing electric equipment.

[0002]

2. Description of the Related Art As a conventional louver for an electric equipment cabinet used for ventilation in an electric equipment cabinet accommodating an electric equipment, a ventilation opening having a rectangular shape and a ventilation opening having a circular shape are known. Further, in the case where the ventilation port has a rectangular shape, screws are fixed at the four corners, so a ventilation fan corresponding to the screw fixing position and the mounting pitch is mounted on the back side of the louver to enhance the ventilation efficiency in the cabinet. However, in the case where the ventilation port is circular, it is common to screw it with a connecting tube part that is connected to the back side of the circular ventilation port, so a ventilation fan is attached to the back side of the louver to improve ventilation efficiency inside the equipment. I couldn't do that.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention The problem to be solved by the present invention is to solve the above-mentioned drawback of the louver having the conventional circular ventilation port, and to provide a ventilation fan despite having the circular ventilation port. It is to provide a louver for an electric equipment cabinet which can be attached to the back side of the louver to enhance the ventilation efficiency in the cabinet, and which does not require any trouble to be attached to the cabinet.

[0004]

A louver for an electric equipment cabinet according to the present invention, which has solved the above-mentioned problems, comprises:
A louver body having a circular ventilation opening and a male screw cylinder portion projecting from the circular ventilation opening on the back surface, a tightening screw having a female screw to be screwed into the male screw cylinder portion, and the tightening screw To
It is characterized by comprising a mounting seat corresponding to a mounting screw hole of a ventilation fan which is mounted to the circular ventilation port via .

[0005]

With such a louver for an electric equipment cabinet, the male screw cylinder portion projecting from the rear surface of the louver body is fitted into the louver mounting through hole provided in the electric equipment cabinet for tightening in the cabinet. Tighten the screw to the male screw cylinder to firmly fix the louver body to the cabinet, and when you want to install the ventilation fan, install the ventilation fan mounting screw hole in the mounting seat arranged around the tightening screw in the cabinet. It should be tightened with screws and attached with a ventilation fan on the back side of the louver body, and the ventilation fan should be activated when necessary to improve the ventilation efficiency in the electrical equipment cabinet.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described in detail with reference to FIGS. Reference numeral 1 denotes a louver main body made of a synthetic resin in which a circular ventilation port 2 is formed in the center and a male screw cylinder portion 3 following the circular ventilation hole 2 is projected on the back surface. Is a nut-shaped tightening screw also made of synthetic resin formed on the inner peripheral surface, and at the outer peripheral edge of the tightening screw 4, there are four mounting screw holes 12 provided in the ventilation fan 11. Four mounting seats 5 having corresponding screw holes 5a are arranged.

In such a structure, the male screw cylinder portion 3 projecting from the rear surface of the louver body 1 is fitted into the louver mounting through hole 20 which is provided in the electric equipment cabinet, and the electric equipment is also mounted. Tightening screw 4 from the inside of the cabinet
The louver body 1 can be accurately attached to the electrical equipment cabinet with a simple number of steps by screwing the male screw cylinder portion 3 into the male screw cylinder portion 3 and tightening it. Next, the mounting screw holes 12 of the ventilation fan 11 are made to face the mounting seats 5 which are arranged at a required interval on the outer peripheral edge of the tightening screw 4 which is tightened to the male screw cylindrical portion 3. By tightening with, the ventilation fan 11 can be easily installed on the back side of the louver body 1 in the cabinet, so that the ventilation fan 11 can be operated when necessary to enhance the ventilation efficiency in the electric equipment cabinet.
In the embodiment, the mounting seat 5 is arranged on the outer peripheral edge of the tightening screw 4.
Although installed, a separate mounting seat 5 is circularly ventilated by the tightening screw 4.
Of course, it may be attached to the mouth 2.
It

[0008]

As is apparent from the above description, the present invention is provided with a louver body having a circular ventilation opening and a male screw cylinder portion projecting from the circular ventilation mouth on the back surface, and a louver body screwed to the male screw cylinder portion. The louver body has a female screw that is attached to the louver body, and the louver body has a male screw cylinder that fits into the louver mounting through hole. Then, not only can the louver body be installed simply by screwing the tightening screw into the male screw cylinder and tightening it, but also let the mounting seat of the louver face the mounting seat that is mounted via this tightening screw. simply by screwing in louvers with circular ventilation openings are those capable of enhancing the ventilation efficiency mounted easily ventilating fan, also if one provided integrally with the mounting seat to the periphery of the clamping screw, The mounting seat is a separate member Of course installation work parts count becomes smaller parts management than in the case there are many advantages such as very easy reduction. Therefore, the present invention solves the problems of the conventional louver for electric equipment cabinets, and has an extremely great practical value in combination with the advantage that the structure is simple and can be provided at a low cost.
