Description

[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a utility pole band used for tensioning a branch line or mounting various types of equipment.

[0002]

2. Description of the Related Art Tightening receiving pieces provided on a pair of band pieces are opposed to each other, and a bolt through hole provided on at least one of the tightening receiving pieces is constituted by a long hole extending horizontally and penetrates the long hole. The head of the tightening bolt screwed with a tightening nut at the tip protruding from the bolt through hole provided on the other one of the tightening receiving pieces is shorter than the lateral width of the bolt through hole configured by the long hole, and has a vertical width. A rectangular pole pole band having a longer one side width and the other side width shorter than the vertical width is known (for example, Japanese Utility Model Laid-Open No. 5-41055).

[0003]

In the conventional structure described above, the head of the tightening bolt is passed through a horizontally long bolt through hole provided in the tightening receiving piece of one band piece, and then the tightening bolt is removed. The tightening nut is turned by a tool such as a spanner while tightening it by 90 ° while the head of the bolt is locked to the upper and lower edges of the bolt through hole. Remove the tightening nut from the tightening bolt on the pillar. Because it can be installed without
Although the workability is very good, the worker is located on the tightening nut side and tightens the tightening nut, so that the tightening bolt head engaged with the tightening receiving edge on the opposite side has upper and lower edges of the bolt through hole. The operator does not always visually check whether or not they are properly locked, but if the tightening nut is tightened while these engagement states are insufficient and the pole mounting work is completed, the band will be temporarily suspended. However, if there is shaking or impact from the wind, the engaging relationship between the head of the tightening bolt and the bolt through hole may be released.In that case, the band may come off the utility pole and cause an unnecessary accident. Happens and is very dangerous.

The present invention has been made by paying attention to the drawbacks of the conventional example.

[0005]

Means for Solving the Problems A pair of band pieces are made to have tightening receiving pieces opposed to each other, and at least one of the tightening receiving pieces is provided with a bolt through hole which is a long hole extending in the horizontal direction. The head of the tightening bolt with the tightening nut screwed to the tip protruding from the bolt through hole provided in the other tightening receiving piece through the through hole is more than the lateral width of the bolt through hole composed of the long slot. Is short and has one side width longer than the vertical width, and the other side width is a rectangular structure shorter than the vertical width, and the horizontal one edge of the bolt through hole formed by the long slot is The configuration is such that it is projected to the outside of the tightening piece.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The drawings show an embodiment of a utility pole band according to the present invention. FIG. 1 is a front view of a main portion before tightening, and FIG.
FIG. 3 is a sectional view taken along line c, FIG. 3 is a sectional view taken along line d-d, FIG. 4 is a sectional view of an essential part in use, and FIG. 5 is a partially cutaway plan view.

In the figure, 1 is a first band piece, 2 is a second band piece, 3 is a first band piece tightening receiving piece, 4 is a second band piece tightening receiving piece, and 5 is one tightening receiving piece 3. And 6 denote bolt through holes provided in the other tightening receiving piece 4, respectively.

The bolt through hole 5 on the side of the first band piece 1 is a long hole that is long in the horizontal direction, and one end edge of the bolt through hole 5 in the horizontal direction is projected toward the outside of the tightening receiving piece 3 and bulges out. Edge 1
0 is provided.

The bolt through hole 6 on the second band piece 2 side
May be the same as the first band piece 2 bolt through hole 5 as long as the tightening bolt 7 can pass therethrough.

Further, 7 is a tightening bolt which penetrates through the bolt through holes 5 and 6, and 8 is a tightening nut which is screwed onto the tip of the tightening bolt 7 protruding from the bolt through hole 6. The tightening bolt 7 has a rectangular head 9 having a side width shorter than the lateral width a of the bolt through hole 5 and longer than the vertical width b, and the other side width shorter than the vertical width b. It is a thing.

The tail ends of the first and second band pieces 1 and 2 are connected to the third band piece 11 by connecting bolts 12 and nuts 1.
Connected by 3.

Then, the band is attached to the electric pole so as to be passed between the tightening receiving edges 3 and 4, and the head 9 of the tightening bolt 7 previously assembled to the tightening receiving edge 5 with the tightening nut 8 is attached to the other side. The band of the embodiment is fixed to the electric pole by engaging with the tightening receiving edge 3 and then tightening the tightening nut 8 screwed to the tip.

[0013]

[Effect] Since the present invention is as described above, since the band body can be fixed to the utility pole without removing the tightening nut from the tightening bolt on the pole, the tightening nut etc. is accidentally dropped during the work on the pillar. The installation work can be done quickly without worrying about causing it, and the workability is excellent, and even if the tightening state of the tightening bolt head is initially insufficient, the tightening nut tightens the head and the head expands. It is forced to rotate along the slope of the car, and as a result, it rotates 90 ° and stays in its original position, so it always has a perfect locked state, so it is excellent in safety, practical and useful idea. .
