BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for adjusting a mounting angle of a board mounted with a breaker or a conductive member or a frame mounted with a door with respect to a box mounted on a wall surface. Such a device, when the box is tilted and attached to the wall surface, when viewed from the surface using its function,
It is a device for attaching a visible makeup cover or door to a box body without tilting, in other words, for attaching the makeup cover or door to the box body while tilting.

[0002]

2. Description of the Related Art Conventionally, as this type of angle adjusting device,
There were those shown in FIGS. 3, 4 and 5. Both are for adjusting the mounting angle of the frame body to which the door is mounted, but the same applies basically to a substrate to which a breaker or a conductive member is mounted. In FIG. 3, the rotation center of the frame body 2 with respect to the box body 1 is a virtual point substantially at the center of the arrangement of the mounting screws 3, 4, 5 and 6 at four locations. When the frame body 2 is rotated right and left by the screw through holes 7, 8, which escape from the loci of the screws 3, 4, 5, 6 attached to the box body 1 relative to the frame body. 9 and 10 are provided on the frame body, and the frame body can be screwed to the box body at any angle. As shown in FIG. 4, the screw through-holes 7, 8, which have escaped the relative movement locus of the screw with respect to the frame body so that the frame body 2 is rotated around the screw 3 or 6,
The frames 9 and 10 are provided. Further, as shown in FIG. 5, the frame body is provided with screw through holes 8 and 9 which escape the relative movement path of the screws 3 and 5 with respect to the frame body so that the frame body 2 is rotated around the screw 4. ing.

[0003]

However, such an apparatus has the following inconveniences.

In the conventional example shown in FIGS. 3 and 4, the angle of the frame body is not determined with respect to the box body when the screws are not completely tightened, which is difficult to handle. In other words, it is difficult to tighten the screws while supporting the frame with two hands until the screws are tightened, and it is difficult to tighten the screws. There was a risk of it. In that respect, in the conventional example shown in FIG. 5, the frame 4 is supported by the screw 4 with one hand and the left side of the figure is set to a desired angle and held, and the screw 3 is temporarily tightened with the remaining hand. Since it is fixed to the box body, it is only necessary to tighten the screws 5 and 4 after that, but the work can be done easily, but if the screws 3 and 5 are not tightened sufficiently, the screws loosen and the left side of the frame penetrates the screw. There was an inconvenience that it fell down to the full hole. Particularly in recent years, construction technology has advanced, and it is less likely that the box body will be installed on the wall surface with a large inclination, and when the frame body slides down, the left side of the frame body looks extremely lowered and it looks It was easy to become a problem.

[0005]

SUMMARY OF THE INVENTION Therefore, the invention of the present invention is, firstly, for mounting a frame body to which a door is attached and a substrate to which a breaker or a conductive member is attached to a box body by adjusting an angle and tightening a screw. The workability is good, and secondly, even if the mounting screws are loosened, the frame and the board can be displaced only up to the mounting angle of the wall surface of the box body, and the angle adjustment device of the distribution board that can not notice the tilt deviation is provided. There is to do.

Explaining an actual construction method when the above-mentioned angle adjusting device for the distribution board is used, the case 100 is fixed to a predetermined portion of the wall surface 500 with screws or the like. After that, a breaker and a conductive member, which are not described, are fixed inside the case. At this time, when a person stands in front of the wall and looks at the wall, the case attaches to the lower right. Next, the screws 201, 202, 203, and 204 are attached to the screw holes 101, 102, 103, and 104 of the case so that the gap between the head of the screw and the screw hole does not come into close contact with each other and a gap larger than the thickness of the frame can be secured. Lightly tighten. Next, the screw through holes 301, 302, 303, 3 of the frame 300 to which the door 400 is attached
Part of holes 04, 3013, 3023, 3033, 304
3, the head of screws 201, 202, 203, 204 is passed through and the frame 201 is attached to the box 100.
Hang on 202, 203, 204 and hang it. If left as it is, the frame is tilted downward to the right according to the tilt of the box by the screws 201, 202, 203, 204.
320 on the right side of the frame 300 centering on the screw 201 on the upper left
Is lifted to correct the inclination of the frame body, and while holding the frame body with one hand, tighten the screw 203 with the remaining hand to fix the frame body to the box body for the time being. After that, the remaining screws 201, 202,
When 204 is tightened, the frame is completely fixed to the box without tilting.

If the box body is installed tilting downward to the left, the frame body is lifted with the left side of the frame body around the screw 203 and the remaining screws are tightened, and the angle is similarly corrected to fix the frame body. It can be fixed.

In the above work, when correcting the angle of the frame body, the frame body can be supported by the one end of the frame body by the screws 201 or 202 while lifting the other end portion of the frame body. The weight burden on the body is halved, and the frame can be easily supported with one hand, and if you tighten the screw on the side lifted with the other hand, the frame will be attached to the box with the angle corrected for the time being, so the frame Can be done very easily by tightening the remaining three screws without supporting them by hand.

Further, the screw through holes 301, 302, 30
Since the holes through which the screw head can pass through are provided continuously in 3, 304 with the inner peripheral edge of the screw through hole being the same,
It is possible to lightly attach 202, 203, and 204 to the box body 100 and then attach the frame body by hooking it on the screw, and press the frame body against the box body to support it, and tighten the screw through the frame body. Is eliminated, and work can be done easily in this respect as well.

The above is an example of the case where the box 100 is tilted and attached to the wall surface. If the box is falling to the right, the right side of the frame is lifted, and if the box is falling to the left, the frame is lowered. The left side of the
It is not necessary to lower the left side of the frame body 300 or lower the right side 320 of the frame body 300 with respect to the screw 203.
Therefore, the screws 201 and 203 are connected to the screw through holes 301 and 303.
Even if the frame body 300 is set so as not to be tilted relative to the box body 100 in a state in which the box body is fully tilted to the upper side of FIG. If attached to the wall, screws 201, 201
02, 203, and 204 include screw through holes 30 of the frame 300.
The frame body is attached to the wall surface without tilting just by hooking and placing 1, 302, 303, 304. In other words, even if the screws are loosened after the frame is attached, the frame does not deviate from the box and tilt greatly. However, in the above-mentioned conventional example, when there is no inclination deviation of the frame body with respect to the box body, the screw is positioned almost in the middle of the elongated screw through hole, so when the screw loosens, the weight of the frame body against the box body There was a possibility of falling down and tilting.

The present invention can also be applied to a substrate to which a breaker or a conductive member is attached as shown in FIG. In FIG. 6, 100 is a box, 201, 202, 203, 204
Is a screw, 9 is a board, and breakers 6, 6'are attached to the board 9.
The conductive cover 8 is attached, and a decorative cover (not shown) that covers the front surface of the distribution board is also attached to the substrate. Box 1
When the angle of the substrate 6 is adjusted with respect to 00, the decorative cover has a structure in which the angle is adjusted integrally with the substrate 9. 90
Reference numerals 1, 902, 903, and 904 denote screw through holes having the same structural shape as the screw through holes 301, 302, 303, and 304 shown in FIG. The method and effect of mounting the substrate and adjusting the angle with respect to the box mounted on the wall surface are the same as those shown in FIG.

[0021]

As described above, according to the invention of the present application, a frame cover attached to a door, a breaker, a conductive member, and a decorative cover for covering a front surface of a distribution board are attached to a box body attached to a wall surface. The workability when adjusting the tilt of the board to be installed and tightening the screws is good, and even if the screws loosen after installation, the frame and board do not slide down more than the box body and tilt, and the box body does not tilt and mounts on the wall surface. If so, it is possible to obtain a device for adjusting the mounting angle of the distribution board that does not require tilt adjustment.
