Description

[Detailed description of the invention] Various types of utility pole band tighteners are known, but the worm tightening type is easy to handle and operate, so it is suitable for installing relatively simple and lightweight equipment. However, this method is not adopted because the extra length of the free end of the band that is fed out due to tightening protrudes and is dangerous.

Therefore, the present applicant proposed a device described in Japanese Utility Model Publication No. 57-40326 (Utility Model Application Publication No. 56-15805).
In this invention, the free end of the band sent out by a worm is received between the band wrapped around the utility pole, thereby preventing it from coming out. For this purpose, a space is required to accommodate the above-mentioned feed, and bending protrusions are formed on both sides of the end of the band facing the worm mechanism, facing the utility pole, to separate the band from the surface of the utility pole. Because of the bending protrusion processing at one end of each band, it is not possible to cut a long band to the required length, and each band must be processed individually, which is uneconomical.

This project solves the above problems, and as shown in the drawing, a tightening worm 1, a worm housing 2 that holds the worm 1 in a manner that prevents it from coming out, and a long hole 4 that engages with the screw of the worm 1 are arranged in a row. When attaching the device 5 by fixing one end of the band 3 to the housing 2 and winding it around the utility pole P, the free end 3a of the band is tightened so that the free end 3a of the band is on the outer surface of the fixed side 3b of the band. A band passage hole 2a is provided in the housing 2 so that the band can be fed out, and the device 5 is positioned on the feeding side, and a recess 5a is formed in the device 5 to receive the feeding band end 3a. This is a device for attaching a device to a utility pole, which consists of a band with a tightening worm located on the opposite side of 5 and the device.

With the above configuration, the end 3a of the band 3 that is tightened and sent out can be stored in the recess 5a of the instrument 5 and installed without protruding outside as shown in the figure. The disadvantage of protrusion is eliminated, and the worm tightening type band tightening device can be applied to tightening utility pole bands. Note that it is better to use a left-handed thread for the worm so that the direction of rotation when tightening the worm is in the right direction R of the turning hand. Moreover, since it is only necessary to weld one end of the band 3 to the worm housing 2, the band can be mass-produced at low cost by cutting a long object and punching a long hole that engages with the worm, compared to the above-mentioned known example. Economical and highly practical.

The illustrated device 5 is an example of a hollow triangular scaffold metal fitting formed by sheet metal press molding, and in the case of various other equipment support brackets, a recess or space for receiving the band end is provided on the side to be pressed by the band. It is.

[Brief explanation of the drawing]

FIG. 1 is a perspective view of the proposed mounting device, and FIG. 2 is an enlarged cross-sectional view thereof. 1 is a tightening worm, 2 is a worm housing, 3 is a band, 4 is a long hole, 5 is an instrument, and P is a utility pole.

Claims (1)

[Scope of utility model registration request] A tightening worm 1, a worm housing 2 for retaining the worm 1, and the worm 1.
When the band 3 is fixed at one end to the housing 2 and is wound around the utility pole P to attach the appliance 5, the free end of the band is tightened. A band passage hole 2a is provided in the housing 2 so that the band 3a is fed out onto the outer surface of the fixed side 3b of the band, and a recess 5a is provided in the device 5 to position the instrument 5 on the side from which the band is fed out, and to receive the feeding band end 3a. A device for attaching a device to a utility pole, which is composed of a band and a device, and is provided with a tightening worm with a rotating part 1a of the worm located on the opposite side of the device 5.
