Description

[Detailed Description of the Invention] The present invention relates to an end connection fitting for ropes such as wire ropes.

Conventional means for connecting the ends of ropes include bundling, braiding, and wire clips. However, bundling spoils the appearance and is easy to unravel; braiding is impossible for amateurs and takes too much effort; and in the case of clips, it is necessary to use multiple clips, and the left and right bolt nuts on the clips must be tied together. It is complicated, as it requires uniform tightening, and has various drawbacks, such as long bolts that protrude and are dangerous.

The present invention aims to provide a rope end connecting fitting that can eliminate such conventional drawbacks, and its features include a pair of opposing holders each having a pressing portion on the inner surface and a wedge-shaped hole at the tip. The proximal ends of the ropes are connected so that one of the supports is centered around the eccentric position of the base end, and the opposing wedge-shaped holes are tightly connected using a fixing device, and the end portion of the rope is clamped by the pressing part on the inner surface of the support. At the same time, the end of the rope is inserted and protruded into one of the wedge-shaped holes, and the rope is tightened by the pressing part and bit into the wedge part by the tightening force of the fastener.

Furthermore, by setting the eccentric position of the proximal end of one of the holders as the center of rotation, the rope can be inserted smoothly by rotating the holder open, and the rope can be reliably compressed by rotating the holder closed. .

Further, the structure and operation of the present invention will be explained in detail with reference to illustrative drawings.

As shown in Figure 1, Figure 2, and Figure 4, the stepped portion 1
A pair of receivers 4 and 5 are facing each other, each having a pressing portion 2 projecting inwardly and downwardly from the center, and having a wedge-shaped hole 3 narrowing downwardly at its tip. The pressing portion 2 may or may not be provided with a plurality of protrusions 6.

As shown in Figure 1, Figure 3, and Figure 4, a pair of receivers 5
A pair of horizontally elongated receiving plates 7 are fixed 8 by welding or screws to the base end of the receiver 4, and the outer eccentric position of the base end of the receiver 4 is pivoted 9 to the other side of the receiving plate 7. .

A space 11 is formed by a stepped portion 1 above approximately the center of the opposing receivers 4 and 5, and a fastener, such as a bolt 12, is inserted into the opposing wedge-shaped hole 3 and screwed with a nut 13. .

Then, as shown in FIG. 3, the receiver 4 is rotated approximately 180 degrees, and the wire rope 15 is inserted through the gap 14 between the proximal ends of the receivers 4 and 5. In this case, since the eccentric position of the proximal end of the receiver 4 is the center of rotation, a gap 14 is formed in which the wire rope 15 can be smoothly inserted by rotating 180 degrees.

Next, the end of the wire rope 15 is inserted into the wedge-shaped hole 3 of the receiver 5, and then the receiver 4 is rotated to the normal position shown in FIG. Then, due to the eccentricity of the receiver 4, the pressing portions 2 of the receivers 4 and 5 come close to each other, and the gap 14 becomes very small to support the wire rope 15 with pressure.

Thereafter, a bolt 12 is inserted into the opposing wedge-shaped hole 3 and tightened with a nut 13.
3, the tightening force is generated by tightening the wire rope 15 by the pair of pressing parts 2, and by tightening the wire rope 15 by the lower wedge part 3 of the wedge-shaped hole 3.
Push firmly into part a to firmly connect the rope ends.

In that case, it is easier to tighten by inserting the bolt 12 from the receiver 5 side and screwing the nut 13 onto the receiver 4 side.

Since the present invention has the above configuration, it has the following effects.

Firstly, since the proximal ends of the receivers 4 and 5 having the wedge-shaped holes 3 at the tip of the pressing part 2 on the inner surface are connected, the wedge-shaped holes 3 on both sides can be simply connected with a fastener.
The force tightens the rope at the pressing part 2 and the wedge part 3
Since it is strongly bitten into a, it becomes a connecting metal fitting that can exert a strong connecting force with just one touch operation.

Second, since the eccentric position of the proximal end of one of the receivers 4 is set as the center of rotation, the receivers 4 and 5 can be rotated by opening the receiver 4.
The rope can be smoothly inserted into the space, and the rope can be reliably clamped and supported by the return rotation of the receiver 4, making handling simple and reliable.

Thirdly, the tensile force applied to the rope rubs against the pressing portion 2 and acts to bite into the wedge portion 3a more strongly, resulting in an extremely large connecting force.

Fourthly, the pair of receivers 4 and 5 are arranged close to each other in parallel, making it compact and having a good appearance, no protrusions, and is safe and of high commercial value.

Fifth, as shown in FIG.
The hook 16a of No. 6 can be hooked on, and it can be widely used as a joint fitting that also serves as a clamp, and its effect is great.
