Abstract

PROBLEM TO BE SOLVED: To provide a panel board in which an attachment structure of rails can be simplified and which can be installed with the improved installation performance. SOLUTION: Long metal fittings 4 having long holes 6 are put across left and right bolts 8 and tightened to fix by nuts 10. Rails 2 are put across the upper and lower long metal fittings 4 and holding metal fittings 5, which are bent so as to fit the shapes of the rails 2, are pressed against the rails 2 at arbitrary positions and fixed by screws to fix internal apparatuses.

Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a panel in which electric equipment is mounted on rails arranged parallel to bolts provided at least near four corners on the back inside a box body. The present invention relates to a mounting structure of an inner unit of a distribution board formed by fixing an attached inner unit. 2. Description of the Related Art Rails 3 of a distribution board 31 according to the prior art.
For fixing 2, the mounting bracket 35 from which the bolt 34 protrudes was attached to the box 33, and the rail 32 facing the mounting pitches A and B of the mounting bracket 35 was attached by tightening the nut to the bolt 34. [0003] However, in the method of fixing the rails 32 of the distribution board 31 in the above-mentioned prior art, since the mounting pitches A and B of the mounting brackets 35 differ depending on the manufacturer, for example, renewal or the like. Box 33
If the device is used as it is and only the internal device is to be replaced, the trouble has occurred that the rail 32 cannot be fixed or the mounting bracket 35 must be replaced. SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a distribution board having a simple rail mounting structure and improved workability, and the structure includes two right and left bolts. Pass the long metal fitting with a long hole, tighten and fix with a nut, pass the rail to the upper and lower long metal fittings, and hold the holding metal fitting bent at any position on the long metal fitting so as to face the shape of the rail. The inner machine is fixed by abutment screw. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An internal unit of a distribution board according to the present invention is mounted on a panel mounted on a rail and fixed with a long metal fitting and a holding metal fitting. The long metal fitting is provided with a long hole and a screw hole for fixing the rail, and the holding metal is bent to face the bent structure of the rail. Attach mounting brackets with bolts to the bottom and four corners of the box, insert the bolts of the mounting brackets into the long holes of the long metal fittings, and tighten and fix with nuts. The rail is placed facing the screw hole provided in the long metal fitting, and the holding metal fitting is covered and screwed and fixed. Since the long bracket is provided with a long hole, the mounting position of the long bracket can be moved within the range of the long hole,
The holding metal can also be fixed at any position on the long metal. An embodiment of the distribution board according to the present invention will be described with reference to the accompanying drawings in FIG. [0007] The inner machine (not shown) of the distribution board 1 is a rail 2
A panel (not shown) or the like is attached to the box 3, and is placed on the panel and attached to the box 3. The rail 2 is fixed by the long metal fitting 4 and the holding metal fitting 5. A long hole 6 for fixing the long metal member 4 is formed in the long metal member 4, and the holding metal member 5
It is bent to face the shape of the rail 2. On the bottom surface 7 of the box 3, a mounting bracket 9 on which bolts 8 are erected is mounted. The long metal fitting 4 is passed to the left and right mounting metal fittings 9, the bolt 8 is inserted into the long hole 6 of the long metal fitting 4, and tightened and fixed with the nut 10. Since the long metal member 4 is provided with the long hole 6, the mounting position of the long metal member 4 can be moved right and left within the range of the long hole 6. In the case of replacing only the inner unit of the distribution board by renewal etc., the pitch of the mounting bracket 9 originally attached is
Even if the distance between the rails 2 is not opposed, the adjustment can be performed with the long metal fittings 4. The rail 2 is placed on the long metal fitting 4, the holding metal fitting 5 is covered, and the screw 11 is inserted and tightened and fixed. The holding metal 5 can be fixed at any position on the long metal 4. If the adjustment cannot be made within the range of the long metal fittings, as shown in FIG. 2, the rail 15 can be directly attached to the bottom surface 14 of the box 13 with only the holding metal fittings 12. As described above, in the distribution board according to the present invention, a long metal fitting having a long hole is passed between two right and left bolts.
Tighten and fix with nuts, pass the rails to the upper and lower long metal fittings, fix the inner machine by screwing a holding metal fitting bent so as to face the rail shape at any position on the long metal fittings Therefore, the inner machine can be freely fixed regardless of the pitch of the mounting brackets mounted on the box. In addition, since a member having a special size is not required and can be attached with a standard member, the manufacturing time and cost can be reduced.
