Abstract

A rigid-collision-free transmission line spacer clamp connection structure includes a spacer frame, rotating joint rubber gaskets and spacer connecting clamps, the spacer frame being uniformly provided with a plurality of rotating joint slots that are rotationally connected with spacer connecting clamps, adopting a “spacer frame, rotating joint rubber gasket and spacer connecting clamp body tail” connection form. The spacer connecting clamp has a connecting rod and a clip, the connecting rod being provided with a connecting rod mounting hole at a rear end and the rotating joint slot being provided with a rotating joint rubber gasket and a spacer connecting clamp rotating shaft therein. The spacer connecting clamp rotating shaft penetrates through the connecting rod mounting hole and a rotating joint rubber gasket mounting hole.

First claim

The invention claimed is:

1. A rigid-collision-free transmission line spacer clamp connection structure, comprising:
a spacer frame;
a plurality of rotating joint rubber gaskets wherein each of the rotating joint rubber gaskets is a circular rubber plate, an upper surface of the circular rubber plate being provided symmetrically with two bosses, the shape of the sides of the bosses close to a rotating joint rubber gasket mounting hole being matched with that of an arc-shaped projection on a connecting rod; and edges of the connecting rod at two sides of the connecting rod mounting hole project radially outwards along a connecting rod mounting hole to form arc-shaped projections; and
a plurality of spacer connecting clamps, the spacer frame being uniformly provided with a plurality of rotating joint slots, each of which is rotationally connected with one of the plurality of spacer connecting clamps therein wherein each of the plurality of rotating joint slots is provided symmetrically with two limiting blocks therein, and the lower parts of the bosses are symmetrically provided with two limiting grooves matched with the limiting blocks;
wherein each of the plurality of spacer connecting clamps comprises the connecting rod and a clip, the clip being arranged at a front end of the connecting rod, the clip being provided with an elastic material at the inner side, the elastic material being clamped to the clip, the connecting rod being provided with the connecting rod mounting hole at a rear end; and
wherein each of the plurality of rotating joint slots is provided with one of the plurality of rotating joint rubber gaskets and a spacer connecting clamp rotating shaft therein, each of the plurality of rotating joint rubber gaskets being provided with the rotating joint rubber gasket mounting hole at the center, the spacer connecting clamp rotating shaft penetrating through the connecting rod mounting hole and the rotating joint rubber gasket mounting hole.

2. The rigid-collision-free transmission line spacer clamp connection structure of claim 1 , wherein each of the plurality of spacer connecting clamps further comprises a clip cover plate, the connecting rod and the clip forming an integral structure, a front end of the clip and a front end of the clip cover plate being hinged via a clip rotating shaft, the clip and the clip cover plate being each provided with an elastic material at the inner side, the elastic material being clamped to the clip and the clip cover plate.

3. The rigid-collision-free transmission line spacer clamp connection structure of claim 2 , wherein the clip comprises a horizontal connecting part, a vertical connecting part and a clamp clip body, wherein a lower surface of the horizontal connecting part is connected to a front end of the connecting rod; a first end of the horizontal connecting part is connected to a rear end of the vertical connecting part; a front end of the vertical connecting part is connected to a rear end of the clamp clip body; the clamp clip body is an arc-shaped clamp clip body; and a front end of the clamp clip body is hinged to the front end of the clip cover plate through the clip rotating shaft.

4. The rigid-collision-free transmission line spacer clamp connection structure of claim 3 , wherein the clip cover plate comprises a clip cover plate body and a limiting part, wherein the clip cover plate body and the limiting part form an integral structure, the clip cover plate body being an arc-shaped clip cover plate body, a front end of the clip cover plate body being hinged to the front end of the clamp clip body through the clip rotating shaft, a rear end of the clip cover plate body being connected to the limiting part, a second end of the horizontal connecting part of the clip is provided with a limiting hinge pin which is detachably connected to the clip, and when the clip cover plate body and the clamp clip body form a closed state, the limiting hinge pin is located at the outer side of the limiting part to form a stop limit.

5. The rigid-collision-free transmission line spacer clamp connection structure of claim 4 , wherein the clamp clip body and the clip cover plate body are each provided with one or more clamping grooves at the inner side, and an outer surface of the elastic material is correspondingly provided with one or more clamping blocks, the shape of the clamping blocks being matched with the one or more of the clamping grooves, and the shape of a space defined by the elastic material arranged at the inner side of the clamp clip body and the elastic material arranged at the inner side of the clip cover plate body is matched with the shape of sub-conductors in a bundle of a transmission line.

6. The rigid-collision-free transmission line spacer clamp connection structure of claim 5 , wherein the elastic material is a rubber gasket, and the clamping block is one of cylindrical, strip-shaped, or cylindrical and strip-shaped.

7. The rigid-collision-free transmission line spacer clamp connection structure of claim 1 , wherein the spacer frame is of a double-frame-board structure, with an upper frame board and a lower frame board being correspondingly provided with bumps and grooves receptively, and the upper frame board and the lower frame board being bucked to form the spacer frame.

8. The rigid-collision-free transmission line spacer clamp connection structure of claim 1 , wherein the spacer frame has rivet holes formed in the spacer frame at two sides of the rotating joint slot, and rivets are arranged in the rivet holes.
