[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting structure of a mounting rail for an internal machine such as a distribution board which houses various electric devices.

[0002]

2. Description of the Related Art Conventionally, the inner unit mounting rail of a distribution board is shown in FIG.
Left and right side surfaces 31 of the inner back surface 31a of the box body 31
b, two inner machine mounting rails 3 facing each other near 31b
A plurality of through holes 33 are provided in the inner machine mounting rails 32, 32, and a substantially U-shaped mounting hole 34 is formed at the upper and lower edges, and the through hole 33 is used. A device mounting plate 35 is provided between the inner machine mounting rails 32, 32, and mounting holes 34 at upper and lower edges are formed on the inner back surface 31a of the box body 31.
The mounting bolts 36 provided at the four corners are inserted through the mounting bolts 36, and all the mounting bolts 36 at the four corners are screwed with nuts 37.

Further, as shown in FIG. 7, mounting bolts 36 suspended from the four corners of the inner rear surface 31a of the box body 31 are inserted into the mounting bracket 38 so that the heads 36a of the mounting bolts 36 are vertically suspended. The support bolt 39 prevents the mounting bolt 36 from coming off, and the nut 40 fixes the mounting bolt 36 in a vertically suspended state.

[0004]

However, according to the above prior art, the inner machine mounting rail 32 is screwed to the mounting bolts 36 erected at the four corners of the inner rear surface 31a of the box body 31 with the nuts 37. Therefore, for example, when the inner body mounting rail 32 on which various electric devices are mounted in a state where the box body 31 is previously installed on a wall surface, the inner mounting rail which is provided with various electric devices on the device mounting plate 35 and has increased in weight. 32
Is lifted, and in that state, the mounting hole 3 at the lower edge is
Mounting bolts 3 located on the lower side of the box body 31
It is very difficult to keep the mounting holes 34, 34 aligned with the mounting bolts 36 ', 36' and to continue to lift the heavy internal machine mounting rail 32 because the mounting holes 34, 34 must be directly mounted on the mounting holes 6 ', 36'. Had the disadvantage that it was a difficult task.

[0005] Further, as shown in FIG. 8 (a), an inner machine mounting rail 32 on which various electric devices are mounted is connected to a distribution board 41 mounted on the main body 31 of the box. The mounting bolt 36 'or the mounting bracket 38, or the inner unit mounting rail 32 in FIG.
8B, the inner unit mounting rail 32 is lowered as shown in FIG. 8B, and the inner door 42 of the distribution board 41 cannot be opened or closed.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a structure of an inner machine mounting rail such as a distribution board, in which the mounting operation of the inner machine mounting rail is easy and the durability against impact is extremely excellent.

[0007]

In order to solve the above-mentioned problem, the structure of the inner unit mounting rail according to the present invention comprises a support extending from the lower end edge of the inner unit mounting rail toward the bottom surface of the box body. The support tool has a through hole formed at least in the bearing that faces the mounting hole at the lower edge of the inner machine mounting rail.

[0008] A cushioning member is provided at the lower edge of the support.

In a state in which the lower end of the support provided on the inner machine mounting rail is placed on the bottom surface of the box body, the insertion hole of the support is opposed to the mounting bolt vertically provided on the inner back surface of the box body. It is in.

[0010]

The lower edge of the support provided on the lower edge of the inner mounting rail provided with an equipment mounting plate provided with various electric devices is placed on the bottom surface of the box body, and the inner mounting rail is mounted in that state. Is slid toward the rear side of the box body, the mounting holes provided on the inner rear surface of the box body opposing the mounting holes at the lower edge of the inner unit mounting rail, the insertion holes of the support tools, and the mounting holes at the upper edge. Bolts are inserted, and nuts are screwed onto the respective mounting bolts to fix the inner unit mounting rail to the back of the box body.

A support 3 is provided at the lower end of the main body 2 so as to extend in the direction of the bottom surface 2a of the box body 2. The support 3 has an insertion groove 3c formed between the body 3a and the shaft 3b from above. The insertion groove 3
c, the lower end of the inner machine mounting rail 1 is inserted therethrough, and the main body 3a and the shaft 3b of the support 3 are formed with an insertion hole 4 facing the mounting hole 1a of the lower end of the inner machine mounting rail 1. Yes,
Further, a cushioning member 5 is provided at the lower edge of the support 3.

FIG. 3 is an explanatory view of a mounting structure of the inner unit mounting rail. The lower end of the supporting unit 3 provided on the inner unit mounting rail 1 is placed on the bottom surface 2a of the box body 2, and the supporting unit is mounted. 3 is located at a position opposed to a mounting bolt 6 suspended from a rear surface 2b inside the box body 2, and the support 3 provided on the inner machine mounting rail 1 is attached to the bottom surface of the box body 2. 2a, and in this state, the inner machine mounting rail 1 is
When sliding in the direction b, the boxes oppose the mounting hole 1a of the inner machine mounting rail 1 and the insertion hole 4 of the support 3 in FIG. 2 and the mounting hole 1b at the upper end edge of the inner machine mounting rail 1 in FIG. The mounting bolts 6 provided on the inner rear surface 2 b of the body 2 are inserted, and the nuts 7 are screwed into the respective mounting bolts 6 to fix the inner machine mounting rail 1 to the rear surface 2 b of the box body 2.

The inner unit mounting rail 1 constructed as described above.
