Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a mounting bracket structure for a relay box used when the relay box is mounted on a column.

[Conventional technology]

Generally, to install a relay box on a pillar, as shown in Fig. 6a and b, the relay box 31 is
A structure is adopted in which the relay box 31 is suspended and supported from an arm 41 fixed to a telephone pole by a mounting bracket structure consisting of a support member 37 etc. fixed to the telephone pole.

That is, the mounting bracket structure of this relay box has a substantially U-shaped cross section corresponding to the width of the arm 41, and includes a support member 37 fixed to the upper surface of the relay box 31, and both left and right sides of the support member 37. A pair of threaded rods 38 whose lower ends are irremovably supported by a connecting portion protruding outward from the threaded rod 3

[The problem that the idea attempts to solve]

However, depending on the location where the relay box 31 is attached to the utility pole, it may not be possible to suspend and support the relay box 31 from the arm 41 due to space constraints, and the relay box 31 may be forced to be directly attached to the utility pole. However, since the above-mentioned mounting bracket structure is exclusively used for mounting on an arm, there is a problem that it cannot be applied to a mounting location where direct mounting to a telephone pole is required.

Therefore, in the past, it was necessary to prepare multiple types of relay boxes 31, each with a different type of mounting bracket structure, such as one for direct mounting on a utility pole or one for arm mounting. There was a problem in that a separate mounting bracket structure had to be manufactured, resulting in high costs.

This idea was devised in view of the above-mentioned problems, and its purpose is to make it possible to easily install the relay box either directly on a utility pole or on an arm, and also to simplify the management work. It is an object of the present invention to provide a mounting bracket structure for a relay box that can be easily carried out and also suppress high manufacturing costs.

[Means to solve the problem]

In order to achieve the above-mentioned purpose, this invention has a bottom fixed to the back side of the relay box, and a pair of openings that are erected almost parallel to the opposite side of the relay box and extend along the length of the utility pole. a support member having a side piece, on both sides of which are provided mounting surfaces that form the same plane with each other and an insertion hole through which an attachment band can be inserted; It has a plate-shaped base that is removably installed, and on the side opposite to the mounting surface of the plate-shaped base, there is a side edge that is perpendicular to the plate-shaped base and can come into contact with the arm side of the utility pole, and an insertion hole. a pair of connecting members provided with a locking protrusion having a locking protrusion, and a pressing plate capable of holding the arm between the mounting surface of the supporting member;
one end is lockable in the insertion hole of the locking protrusion,
The present invention further includes a fastening member having a pair of connecting rods whose other ends are fastened to the pressing plate.

[Effect]

Therefore, when the relay box is mounted on the arm of a telephone pole, the relay box is mounted on the pole using the supporting member, the pair of connecting members, and the fastening member. That is, the arm is held between the mounting surfaces of the supporting member, the side edges of the connecting members arranged to face each other, and the pressing plate of the fastening member, and one end is locked in the insertion hole of the connecting member. By tightening the other end of the connecting rod to the pressing plate, the relay box is suspended and supported by the arm.

Also, when directly attaching the relay box to a utility pole, the attachment band is inserted into the band insertion hole of the support member without using the connecting member and the fastening member, and when the band is tightened to the utility pole, the relay box is attached. is firmly attached directly to the utility pole.
