Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a clamp used for attaching spacers, dampers, etc. to power transmission lines.

As shown in FIG. 1, a conventional clamp includes a clamp body 20 and a clamp cap 2 hinged on the body.
1, and hold the wire C with spring 2.
A hook bolt 22 to be tightened through the clamp body 20 is inserted into the clamp body 20 and a hook portion 23 formed at the tip thereof is inserted.
The slide bar 25 is fitted into a pocket provided in the clamp cap 21 via a spring 26.
It was attached to wire C by forcibly engaging it, but
Because the repulsive force of the spring 26 is large, the electric wire C
When installing or removing the clamp body 20 and the clamp cap 21, use a large special tool to fix the clamp body 20 and the clamp cap 21 as shown in FIG. Because the hook part 23 has to be pushed down to engage and disengage from the slide bar 25, work at high places is very troublesome and takes a long time, and the tool is blown away due to the repulsive force of the spring 24 especially during removal. It was dangerous.

The present invention has been made in view of the above points, and an embodiment illustrating the same will be described below.
In FIG. 2, 1 is a clamp body, 2 is a clamp cap hinged to the end of the clamp body 1, and wire gripping grooves 3, 3 are formed in the clamp body 1 and the clamp cap 2. 4 is a bolt insertion hole formed in the clamp body 1, 5 is a screw hole formed in the clamp cap 2, and 6 is a slide plate having sleeve pieces 7, 7, which are formed in the clamp cap 2 as shown in FIG. Sleeve pieces 7, 7 are slidably fitted into the horizontal groove 9 with a spring 10 protruding outward from the horizontal groove, and a semicircular shape is formed in the center of the side surface of the slide plate 6 as shown in FIG. An engagement groove 8 is provided. 11 is an engagement groove 8 of the slide plate 6 at the tip.
A tightening bolt 13 provided with an engagement groove 12 that engages and disengages with the
is a spring that is inserted into the shaft of the tightening bolt 11. To fix the clamp to the electric wire C, the spring 13 is inserted into the shaft of the clamp body 1 from the bolt insertion hole 4 of the clamp body 1. The horizontal groove 9 of the clamp cap 2 is inserted into the engagement groove 12 formed at the tip of the clamp cap 2 by screwing it into the screw hole 5 of the clamp cap 2.
In order to fix the clamp by engaging the engagement groove 8 of the slide plate that is slidably fitted into the clamp cap 2, and to remove the clamp from the electric wire C, use the sleeve pieces of the slide plate 6 that protrude from both sides of the horizontal groove 9 of the clamp cap 2. 7,7 to spring 1
Pull back against the spring force of 0 to disengage the tightening bolt 11 from the engagement groove 12, loosen the tightening bolt 11, and remove it.

According to the present invention as described above, the clamp body 1
A tightening bolt 11 inserted through the bolt insertion hole 4 is screwed into the threaded hole 5 of the clamp cap 2 and slid into the engagement groove 12 of the tightening bolt 11 and into the horizontal groove 9 of the clamp cap 2 via the spring 10. It can be attached to the electric wire C by simply engaging the engagement groove 8 of the freely fitting slide plate 6, and the clamp cap 2
It can be removed from the wire C by releasing the engagement with the sleeve pieces 7, 7 of the slide plate 6 protruding from both sides of the horizontal groove 9 and loosening the tightening bolt 11, so it can be removed from the wire C as in the conventional method. It has excellent effects such as not requiring large special tools for removal, allowing work at high places to be performed easily, quickly and safely, and also being simple in structure, easy to manufacture, and can be provided at low cost.
