Since it is not possible to move integrally with the band piece during the process of winding the band piece around the utility pole, the tightening nut screwed onto the tip side of the tightening bolt cannot be moved by hand or when winding the band piece around the utility pole by manipulator. , The other band piece does not automatically catch on the tightening piece. For this reason,
After winding the band piece around the utility pole, it is necessary to work to lock the tightening nut to the corresponding tightening receiving piece.

The present invention was devised with a view to such a conventional example for the purpose of providing a utility pole band which is easy to use.

[0005]

One or both of a pair of opposing semicircular arc-shaped band pieces are attached to a supporting member or other supporting material for supporting a device, and one end side is supported by one end side or the other band piece. A locking piece for rotating one or both of the band pieces in contact with the electric pole surface is provided at the one end of the band piece screwed to the material, and a tightening receiving member is provided at each of the other ends of the band pieces. In a utility pole band in which a pair of band pieces in which a tightening nut is screwed into the pair of tightening bolts are fastened to a utility pole, one tightening receiving piece that locks the head of the tightening bolt and the tip A pressure spring is interposed between a pressure receiving piece provided at an intermediate portion of the tightening bolt in which the tightening nut is screwed on, and the tightening bolt engages with the other one of the tightening receiving pieces to lock the tightening nut. Notches were provided along the length of the band piece And it formed.

[0006]

[Function] When the free end on the side of the tightening receiving piece is opened and pressed against the utility pole, the locking piece contacts the utility pole and the band pieces are rotated around the hinged part as a fulcrum to wind the band piece around the utility pole. To be done.

Since a pressure spring such as a coil spring is interposed between the pressure receiving piece and the pressure receiving piece that locks the head of the tightening bolt, the tightening bolt is biased by the biasing force of the pressing spring. Without moving during the turning operation, the tightening nut screwed in a certain direction, that is, the tip of the tightening nut, continues to be in the direction of locking to the tightening receiving piece on the side where the bolt head is not locked. When the winding operation is completed, the tightening nuts are arranged at the positions where they are locked to the corresponding tightening receiving pieces.
