Description

[Detailed description of the invention] (Field of industrial application) This invention belongs to the field of power transmission line maintenance, and is used to fix color-coded sheets for line identification to be displayed on the pedestals of steel towers that support power transmission lines. used.

(Prior art) Conventional color-coded sheets for the above-mentioned fields of use are ones that are glued to the pedestals of steel towers, those that are wrapped in aluminum foil, or those that are made of synthetic resin plates that are tied together as L-shaped plates and attached to the tower pedestals. However, the effectiveness of the adhesive decreases due to rain, wind, and snow, and the color-coded sheet peels off.If the color-coded sheet is torn by the glass, it takes time and effort to replace the color-coded sheet. However, synthetic resin plates have inherent problems such as being expensive.

(Problems to be solved by the invention) In order to solve the above-mentioned problems, the present invention provides a fastener that can easily fix color-coded sheets for power transmission line identification to the pedestal of a steel tower. This contributes to improving the efficiency of maintenance and maintenance.

(Means for Solving the Problem) The fastener of the present invention has oblique sides erected on the left and right sides of a slightly horizontal base, and the oblique sides are formed to bulge outward. A locking portion formed by curving the upper end downwardly in an arc shape is disposed at the upper end.

(Function) According to the above configuration, the oblique side of the stopper and the locking part fix the color-coded sheet in an angle shape, and a small space is formed between the bottom side and the corner of the angle.

(Example) To specifically explain the present invention using an example, as shown in FIG. Wind it up and lock the stopper a shown in Figure 2 from above the color-coded sheet 2.
is fixed at angle 1. That is, the fastener a has oblique sides 4, 4' erected on the left and right sides of a slightly horizontal base 3 in a shape that expands toward the end, and each of the oblique sides 4, 4' is formed to bulge outward. At each upper end, locking portions 5, 5' are provided which are curved outwardly and downwardly into an arc shape. The locking parts 5, 5' of the stopper a are attached to the edges 6, 6 of the angle 1.
To lock it, first lock one of the locking parts, for example, the locking part 5, to one edge 6 of the angle 1 around which the color-coded sheet 2 is wound, and then When the opposite oblique side 4' is pressed with a finger in the direction of the other edge 6' of the angle 1, the other locking part 5'
has its outer end tip 7' connected to the other edge 6 of angle 1.
It slides on the inner surface of the edge 6' and is locked to the edge 6'. At this time, the oblique sides 4 and 4' are elastically formed by applying internal stress to bulge outward from the bent part of the bottom side 3. It will be crimped.
When removing the stopper a from the angle 1, since a space 9 is formed between the bottom side 3 and the corner 8 of the angle 1 when it is installed, insert your finger into the space 9 to move the bottom side 3 vertically. When pressed, the locking parts 5, 5' engage both edges 6, 6 of the angle 1.
You can easily get rid of it by gradually moving away from it. Therefore, maintenance such as replacing and attaching the color-coded sheets 2 does not require much effort.

(Effects of the invention) As described above, according to the invention, the color-coded sheet 2 can be firmly fixed to the angle 1 without having to use adhesive on the entire surface, and when it is removed, only the bottom side 3 needs to be pressed. Since the stopper a can be easily removed from the tower pedestal, maintenance such as replacing and fixing the color-coded sheets does not require much effort.
