JP3709104B2 - Sheet scissors for indirect methods - Google Patents

Description

[0001]
BACKGROUND OF THE INVENTION
In the hot line construction of the high-voltage distribution line, this invention covers the charged part of the electric wire with an insulating sheet, so that the insulating sheet is not detached. The present invention relates to a sheet scissors for indirect method used when temporarily fixed to an electric wire.
[0002]
[Prior art]
The sheet clip that has been used in the past has been developed for direct hot wire construction, and the grip portion of the sheet clip is spaced apart like a clothespin, so When the sheet clip is used at the time of construction, the grip part of the sheet clip is sandwiched in the remote operation of the operator by an indirect hot wire tool such as an insulating Yatco attached to the tip of the insulating operation rod. It is very difficult to do so. There was a problem on the work surface such as not being able to
[0003]
[Problems to be solved by the invention]
The present invention has been made to solve the problems described in the prior art, and does not require any special attachments, and provides sheet scissors for indirect methods that can be approached from any direction. It is the purpose.
[0004]
[Means for Solving the Problems]
The sheet scissors for the indirect method of the present invention are provided with large and small concave portions that are gently curved inside the upper and lower jaws, and when the upper and lower jaws are closed by spring force, the surface is slipped and stopped. The flat upper and lower grips are configured so that the upper surfaces thereof are substantially parallel.
[0005]
DETAILED DESCRIPTION OF THE INVENTION
An example of an embodiment of the present invention will be described with reference to the drawings. As shown in FIGS. 1 and 2, large and small concave portions 3 and 4 that are gently curved are formed inside the upper and lower jaw portions 1 and 2, respectively. When the upper and lower jaws 1 and 2 are closed by a spring force, as shown in FIG. 1, the upper surfaces of the flat upper and lower grips 5 and 6 whose surfaces are slipped and stopped are substantially parallel to each other. Has been.
[0006]
The large concave portion 3 can be applied, for example, when gripping a 6.6 KV high voltage pull-down line having a size of 120 to 200 square millimeters and the small concave portion 4 having a size of 5.5 to 58 square millimeters. Molded. Since the recesses 3 and 4 are gently curved as shown in FIG. 1, a relatively rough operation (in the case of using an indirect hot wire tool, an accurate operation directly performed by the operator's hand is expected. However, it is easy to attach the wire of the applicable size to the recesses 3 and 4.
[0007]
The upper jaw part 1 and the upper grip part 5 having the large and small concave parts 3 and 4 and the lower jaw part 2 and the lower grip part 6 having the large and small concave parts 3 and 4 are made of an insulating material such as plastic. 1 is formed in a shape as shown in FIG. 1, and both are rotatably connected to a plastic fixing pin 7. Both ends of the upper and lower grips 5 and 6 are wound around the plastic fixing pin 7 and expanded to the end. The distal ends of the upper and lower jaws 1 and 2 are always closed by the spring force of the metal spring 8 pressed against the lower side. The metal spring 8 is covered with the upper and lower grips 5 and 6 made of an insulator and is not exposed on the surface.
[0008]
The surfaces of the flat upper and lower grips 5 and 6 are, for example, processed in an eye-like shape so that they do not slip when sandwiched by an indirect operation tool such as an insulating yarn, and the surface area is also slightly larger. .
[0009]
【The invention's effect】
Since the present invention is configured as described above, the following effects are exhibited.
(1) When closed, since the upper surfaces of the flat upper and lower grips, which are slipped and stopped on the surface, are almost parallel, the indirect hot tool can be approached from all directions.
{Circle around (2)} Since the small and large concave portions that are gently curved are provided inside the upper and lower jaws, an electric wire of an applicable size can be easily mounted and held in the concave portion even with a relatively rough operation.
(3) Since metal members such as metal springs are not exposed at all, they are safe.
(4) The work of attaching and detaching the insulation sheet becomes easy and the work efficiency is improved.

Claims (1)

Inside the upper and lower jaws (1, 2), there are provided large and small concave portions (3, 4) that are gently curved. A high-voltage power distribution characterized in that the upper surfaces of the applied flat upper and lower grips (5, 6) are substantially parallel and one end in the width direction of the upper and lower grips (5, 6) protrudes.
