Description

[Detailed explanation of the invention] A. Purpose of the invention [Industrial field of application] This invention is designed to attach a tie strap attached to a telephone line or other communication line to a utility pole, mainly a utility pole for a drop-in line, when bringing a telephone line or other communication line to a customer. This relates to a band for hanging.

[Conventional technology]

Conventional communication line anchoring straps have been attached either directly to utility poles or by hooking them to hooks provided through utility pole bands.

[Problem that the invention attempts to solve]

However, the entrance of the above-mentioned conventional hook is open upwards, and the hook for the communication line hold-down strap is simply hooked onto it from above, so if the lead-in communication line swings greatly due to strong winds, etc., the hold-down strap may become loose. There were times when I got off the hook.

It would be possible to provide a snap, a stopper, or other mechanism for preventing the hook from slipping out at the entrance of the hook, but this would result in high costs and problems with durability and workability.

The object of the present invention is to solve the above-mentioned problems in the conventional hook for hooking a communication cable hold-down strap.

B. Structure of the invention [Means for solving the problem] In order to achieve the above-mentioned purpose, the present invention has a part of the band equipped with a tightening bolt/nut at at least one location on the circumference, which is attached to a utility pole. A substantially U-shaped bent part is provided that forms a space between the pole and the telephone pole when it is attached, one end of the U-shaped hook is fixed to the center of the outer circumferential surface of the substantially U-shaped bent part, and the other end is fixed to the substantially U-shaped bent part. Extending in the direction of the center of the band beyond the upper edge of the bent part and bending inward of the bent part, between the extended end of the U-shaped hook and the upper edge of the approximately U-shaped bent part of the band. This communication line anchoring band for a utility pole is characterized in that the diameter and the width between the tip of the extension end and the utility pole are each formed slightly larger than the thickness of the hanging ring of the communication line anchoring strap.

[Effect]

The band is attached around a utility pole in the same way as a regular utility pole band and secured with bolts and nuts.

The communication line anchoring strap is hooked onto the hook by inserting its hanging ring from above between the substantially U-shaped bent part around the extended end of the U-shaped hook and the utility pole.

When the communication line anchoring strap flips up, its hanging ring hits the upper side of the U-shaped hook, and even if it tries to move toward the utility pole at the same time as it flips up, it also hits the extended end of the U-shaped hook and the roughly U-shaped bent part of the band. blocked by the edge.

〔Example〕

Figure 1 shows band 1 of the present invention attached to a utility pole for service wires.
FIG. 3 is a perspective view showing a state in which a communication line holding strap S is attached to and hooked to.

The band 1 is made by bending a banded iron plate made of mild steel or the like into a circular shape surrounding the utility pole P, forming a pair of facing tabs 2, 2 bent outward at each end, and A U-shaped bent portion 3 that protrudes outward is formed in a part. The bent portion 3 is not limited to the U-shape, but may be U-shaped, semicircular, or the like.

A hole 5 through which a tightening bolt 4 is passed is opened in the center of each of the ear pieces 2, 2. The nut attached to bolt 4 is hidden behind ear piece 2. Reference numeral 6 in the figure indicates a punched hole for improving the flexibility and reducing the weight of the band 1.

At the center of the outer peripheral surface of the U-shaped bent portion 3 of the band 1,
One end 7A of the U-shaped hook 7 is welded. U
The other end 7B of the hook 7 extends beyond the upper edge 3A of the U-shaped bent portion 3 toward the center of the band 1.
Further, it is bent downward, that is, toward the inside of the U-shaped bent portion 3, into an F-shape.

As shown in FIGS. 2 and 3, the U-shaped hook 7
between the extended end 7B of the band 1 and the upper edge 3A of the U-shaped bent portion 3 of the band 1 = D1, and between the tip of the extended end 7B of the U-shaped hook 7 and the circumferential surface of the utility pole P = D2, Each of them is formed to be slightly larger than the thickness of the hanging ring R of the communication line anchoring strap S.

After hanging the steel core wire W1 of the telephone line W on the main body of the communication line holding strap S, the hanging ring R is attached to the utility pole P and the U-shaped bent part 3 of the band 1, as shown by the chain line. It is fitted from above between the extended end 7B of the enclosed U-shaped hook 7 and hooked onto the U-shaped hook 7.

C. Effects of the invention Since the communication line anchoring band for utility poles of the present invention has the above structure, the communication line anchoring strap can be easily hooked onto the U-shaped hook fixed to the outside of the approximately U-shaped bent portion of the band. can. However, once it is hooked, it will not fall off the U-shaped hook even if the communication line is agitated by wind or the like and the tie strap flips.

Moreover, the number of parts is small and it can be easily manufactured, and it is robust and can be provided at low cost.

Claims (1)

[Scope of utility model registration request] A part of the band equipped with a tightening bolt/nut at at least one location on the circumference has a roughly U-shaped bent part that forms a space between the belt and the pole when attached to the pole. One end of the U-shaped hook is fixed to the center of the outer peripheral surface of the bent portion, and the other end extends toward the center of the band beyond the upper edge of the approximately U-shaped bent portion, and extends inside the bent portion. The extended end of the U-shaped hook and the approximate U of the band.
A communication line anchoring band for a telephone pole, in which the distance between the upper edge of the letter-shaped bent part and the distance between the tip of the extension end and the utility pole are each slightly larger than the thickness of the hanging ring of the communication line anchoring strap.
