Description

[Detailed Description of the Invention] This invention relates to a plate for determining the position of a connection hole of a conduit when connecting the conduit to a distribution board, pool box, etc.

Traditionally, power distribution boards, pool boxes, etc. (hereinafter referred to as "boxes, etc.")
In order to connect conduits, the positions and sizes of the connection holes in the conduits and boxes, etc., were determined each time using a ruler and a raking needle.

Therefore, determining the dimensions is not only complicated, but also requires considerable skill to distribute the connection positions of the plurality of conduits connected to the box etc. in an attractive manner.

The object of this invention is to provide a plate that allows the position and size of the connection hole of the conduit to be determined very easily.

An example will be described below based on the drawings.

A center hole 2 is passed through the center of the disc body 1, and fan-shaped through holes 3, 3 are provided on the disc body 1 apart from the center hole 2.

The circumferential edges 4 of the through holes 3, 3 are arcuate with the center of curvature being the center of the central hole 2.

The disc body 1 has through holes 5, 5, and the through holes 5
, 5, a magnet 6°6 is fixedly attached thereto.

In this embodiment, the small pieces 7, 7 are extended around the disc body 1, so that when a plurality of disc bodies 1 are arranged on the surface of a box or the like, a constant spacing can be maintained. This is preferable because the conduit pipes can be connected while maintaining the distance, but it is not necessary.

In order to manufacture the plate t-A of the present invention, in addition to making the disk body 1 from a synthetic resin plate or a metal plate and fixing a magnet, the disk body 1 is made from a magnetic metal plate or a rubber magnet sheet. Naturally, it is also possible to fabricate a magnet, and the latter case is advantageous because there is no need to separately fix the magnet.

Further, the outer diameter of the disc body 1 in the present invention is approximately equal to the diagonal distance of a lock nut used when fixing a conduit to a box etc., and the radius of curvature of the edge 4 of the through hole 3°3 is:
Slightly larger than half of the outer diameter of the conduit is appropriate.

Next, how to use plate A of the present invention will be explained.

The plate 1-A for each conduit is adsorbed to the surface to which a group of conduit such as a box is to be connected in an optimal arrangement relationship, and the plate 1-A for each conduit is attached to the surface of the box etc. along the edge 4 of the through hole 3 of each plate A. Mark and mark.

Next, after drilling a through hole through the center hole 2 of each plate 1-A, the plate A is removed.

Then, expand the drill hole with a hole saw or reamer, and first,
Make the hole a diameter that reaches the mark made along the edge 4, insert the end of the conduit into this hole, and fix the conduit to a box or the like with a lock nut.

As described above, with the plate A of the present invention, if a plurality of plates of several different sizes are prepared according to the thickness of the electric conduit, etc., the sizing operation can be carried out very easily.

In addition, plate A can be magnetically attracted to a box, etc., so when connecting multiple conduits of different sizes to the surface of a box, etc., the plate can be regarded as a model for positioning the conduits. At the time of positioning, it is very convenient because the optimum arrangement can be performed after moving and looking at various things, and there is no room for mistakes in dimensioning.
