Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention is arranged at the top of utility poles to cut off or introduce the flow of electricity to the electric wires installed between the utility poles. This invention relates to display tags attached to switches used for this purpose.

[Technical background of the invention and its problems]

As is well known, when performing power outage work, it is customary to operate a switch placed on a utility pole to interrupt the current flowing through the electric wires in a predetermined construction section. In the conventional switch 20, as shown in FIG. 6, an arm 13 is attached to the wall surface of the switch main body 11, the central part of which is fixed to a shaft, and the arm 13 is swingable about the shaft 12 as a fulcrum. Arm 13
By pulling downward one of the drawstrings 14 connected to both ends of the arm 13, the arm 13 is swung about its axis 12, thereby cutting off or turning on the flow of electricity within the switch main body 11. I'm starting to do that.

The switch that is operated in this way to cut off and turn on the current is placed at the top of the utility pole, and during electrical work it is necessary to check whether the switch is in the ``cut off'' or ``on'' state. In this case, the decision was made by looking at the inclination of the arm 13 and the hanging condition of the drawstring 14 (which drawstring hangs further downwards).

However, switches are usually placed quite high on utility poles, and it is not always easy to accurately judge the status of the switch by looking at the tilt of the arm or the hanging condition of the pull cord from the ground. It is impossible to see the condition of the arm from the opposite side of the arm, and the status of the pull strings at both ends of the arm cannot be determined due to the obstruction of the utility poles, allowing safe and quick electricity supply. There were serious obstacles to carrying out construction work.

[Purpose of invention]

The present invention was developed based on the above-mentioned circumstances, and can be easily attached to the drawstring hanging from the arm of an existing switch, allowing the current status of the switch to be accurately confirmed at a glance from the ground. The purpose is to provide display tags for switchgear that can be obtained.

[Summary of the idea]

The outline of the present invention for achieving the above object is that a guide groove for guiding a drawstring on the central imaginary line is provided on the opposite sides of the display board bodies of the same form constituting a pair, and a loop for the drawstring is provided at the upper end on the central imaginary line. a protrusion into which the corner part is fitted and has a corresponding surface in the same direction; a protrusion and a fitting hole arranged in parallel at equal distances on both sides of the imaginary line; and a projection having sloped surfaces in the same direction on both sides of the guide groove, and An upright piece having a locking portion at the lower edge of the inclined surface is provided on each of the upright pieces, so that the display plate bodies having display symbols attached to the opposite surfaces of the display plate bodies can be fitted face-to-face with each other. It is characterized by

The protrusions 4 and the fitting holes 5 are arranged at the upper and lower parts of the display board 1, respectively, so that the male and female shapes of the parallel protrusions 4 and the fitting holes 5 match. There is. The pair of upright pieces 6 facing each other are provided in a protruding manner in the vicinity of the convex portion 4 and the fitting hole 5, respectively, which are respectively arranged at the upper and lower parts. The tip portion is approximately wedge-shaped, and an inclined surface 6A is formed in the same direction in the wedge-shaped tip portion, and a flange portion 6 is formed on the lower edge of the inclined surface 6A.
B is provided. A rectangular hole 7 of a size into which the upright piece 6 can be inserted is bored close to each upright piece 6 on the inclined surface 6A side of each upright piece 6 .

In the figure, 8 is a step support surface that joins the pair of display boards 1, 1 when they face each other, and 9 is a support surface that connects the pair of display boards 1, 1 to each other when they face each other, and 9 is a support surface that connects the pair of display boards 1, 1 to each other when they face each other.
This is the lower end depression formed on the top.

On the other hand, on the opposite side of the pair of display boards 1, 1, there is attached a display code 30 that indicates, for example, "off" which means the switch is cut off, or "on" which means the switch is turned on. (In Fig. 2, "ON" is indicated).

A pair of display board bodies 1, 1 configured as described above
When attaching the cords to the drawstrings hanging from both ends of the switch arm, proceed as follows.

First, the pair of display boards 1, 1 are joined face-to-face so that the hanging drawstring 14 is sandwiched from both sides. At this time, the ring portion 14A of the drawstring 14 fits into the projections 3, 3 of each display plate body 1, 1, and the drawstring 14 is guided to the guide grooves 2, 2 and the lower end recessed portions 9, 9. to be located. In addition, the display board 1,
1 face each other, so that the corresponding surfaces 3A, 3A of the protrusions provided on the facing sides, the protrusions 4, 4 and the fitting holes 5, 5, and the inclined surfaces 6A, 6A of the upright pieces are arranged in opposite directions. It's summery. Therefore, the tips of the corresponding surfaces 3A, 3A of the respective protrusions on the facing display board bodies 1, 1 are joined, and the respective protrusions 4 are shallowly fitted into the facing fitting holes 5, and further, The inclined surface 6A of each upright piece is lightly joined to the inclined surface 6A of the opposing upright piece.
