  Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a configuration diagram showing a configuration of a marker ring according to the present invention. FIG. 1b is a front view of the marking ring of the present invention, and FIG. 1a is a side view of the marking ring of the present invention. In FIG. 1, a sign ring 100 of the present invention includes a conductor gripping part 10 that grips a conductor that is an overhead power transmission line, and a sign body 20 that is suspended below the conductor gripping part 10.

  The conductor gripping portion 10 has an opening ring structure, one end of the opened conductor gripping portion 10 has a convex shape A, the other end has a concave shape B, and the conductor gripping portion 10 has a marker on the concave shape side. A sign body hanging hole fitting 15 for attaching 20 is provided. The sign body 20 includes a sign piece 24 that indicates the presence of an overhead power transmission line, and a rod-shaped connecting portion 22 that penetrates the sign object suspension hole fitting 15 on the sign piece 24. The attachment of the sign ring 100 to the overhead power transmission line and the sign effect are the same as in FIG.

  FIG. 2 is an enlarged view of the conductor gripping portion of the present invention. FIG. 2 a is an enlarged view of the conductor gripping portion 10, and FIG. 2 b is an enlarged view of the convex portion A and the concave portion B. 2 is the same as FIG. 5 except that the marker suspension hole fitting 15 is provided on the concave portion B side of the conductor gripping portion 10, and thus the description thereof is omitted.

  FIG. 3 is a marker ring attachment diagram showing a state in which the marker ring of the present invention is attached to the overhead power transmission line. In the sign ring 100 attached to the overhead power transmission line 40 in FIG. 3, the sign piece 24 hangs perpendicularly to the ground direction when there is no wind, but in a light wind condition, the sign piece 24 sways to the left and right to make it easier to recognize its presence. This is the same as in the case of FIG. However, when strong wind or an equivalent external stress F is applied in the direction of the arrow, the concave portion B presses the convex portion A toward the outside, so that the fitting becomes stronger, the fitting is released, and the conductor gripping portion 30 is opened. As a result, the overhead transmission line cannot be gripped. For this reason, the trouble that the sign ring 200 is detached from the overhead power transmission line 40 and falls to the ground can be prevented.

  Thus, since the obstacle that the sign ring is detached from the overhead power transmission line and falls to the ground can be prevented, the sign ring capable of maintaining the gripping force of the overhead power transmission line against external stress can be provided. . Further, by attaching a plurality of marker rings to the overhead power transmission line, the presence of the overhead power transmission line can be recognized more safely and easily, and necessary attention can be drawn.
