Description

[Detailed description of the invention] This invention relates to high-hanging hardware for outdoor electric wires, and in particular to improving high-hanging hardware that uses flexible reinforced plastic (for example, glass fiber-filled plastic) for the high-hanging rod. .

Conventionally, it has been known that reinforced plastics containing glass fibers have been used as high-end rods, and it is also known that this has considerable advantages over those made of steel.

However, in this type of high-mounted hardware, the high-end rod naturally bends due to wind pressure, etc., so the lower end of the circular rod and the hollow part of the cylindrical support hardware fit together or are screwed together. The conventional method of connecting rods and supporting metal fittings has the disadvantage that wear and damage tend to occur between the lower end where the rod is supported and the supporting metal fittings, and as a result, the mode of support becomes unstable over time.

In order to eliminate such drawbacks, the present invention is characterized by improving the lower end of the elevated rod and the receiving portion of the supporting hardware so that the elevated rod can be supported in a stable manner over time.

Next, an embodiment of the present invention will be explained with reference to the drawings.

Reference numeral 1 is a high-rise hardware according to the present invention, which is made of a high-rise rod 2 made of glass fiber-filled reinforced plastic, a support metal 3 having a holding cylinder part 4 that supports the lower end of the rod 2, and a mounting bracket 5 for attaching to a building. ing.

Reference numeral 6 designates a wire retaining hook attached to the tip of the rod 2, 7 a wire clasp provided on the rod as required, and 8 a through hole for a fastener formed in the mounting fitting.

Reference numeral 9 denotes a downwardly facing truncated conical fixing section integrally provided at the lower end of the high upper rod, and a fixing bolt 10 is provided downwardly protruding from the circular mound along the downward extension axis of the rod 2, but in this example, A case is shown in which a circular mound 9' having a smaller diameter is formed at the lower part of the boundary part 9 and protrudes from this part.

The hollow part of the holding cylinder part 4 is a funnel-shaped hole 11 into which the fixing head part 9 of the upper force button 2 is tightly fitted from above, and the lower hollow part 12 is a funnel-shaped hole 11 through which the fixing bolt 10 of the rod 2 passes. This is a through hole that extends downward from the holding cylinder.

In addition, in this example, the small round tomb part 9' of the boundary part 9 also has a hollow part 12.
It is designed to fit loosely.

Numeral 13 is a fastening nut that is combined with bolt 10 to fix rod 2 to holding cylinder portion 4, and 14 is a washer.

Since the present invention is constructed as described above, even if the high rod fixed on the holding cylinder part 4 is bent due to wind pressure, etc., the fixed neck part 9 at the lower end is in the form described above, so that the rod 2 is not bent. This reduces the resistance of the retaining cylinder against the wear and tear, thereby significantly reducing wear and tear.

Further, since the fixing bolt 10 is provided protrudingly along the downward extension axis of the high upper rod and is combined with the fastening nut 13 to fix the rod 2 on the holding cylinder, it may be provided in any other manner for the same purpose. This also has the advantage that the resistance to bending of the rod 2 is lower than in the case of the rod 2, and inconveniences such as breakage caused by this can be minimized.

Claims (1)

[Scope of utility model registration request] A high rod made of glass fiber-containing reinforced plastic, which is equipped with a wire anchoring hook at the upper end, and has a downwardly facing truncated conical fixing boundary part 9 and a fixing bolt 10 projecting downward from the fixing lever part at the lower end. and; the attachment part to be attached to the building and the fixed boundary part of the above-mentioned high rod are cut out from the supporting hardware having the holding cylinder part 4 which is fitted and supported from above, and the above-mentioned fixing bolt is cut along the downward extension axis of the high above rod. The hollow portion of the holding cylinder has an upper portion formed into a funnel-shaped hole into which the fixing boundary portion 9 is tightly fitted, and a lower portion formed into a through hole through which the fixing bolt 10 is loosely inserted.
The high rod is fixed on the holding cylinder in such a manner that the fixing bolt engages a nut on the outside of the lower surface of the holding cylinder 4 and tightens the cylinder between the fixing boundary of the high rod and the nut. High-grade hardware for outdoor electric wires.
