The technical scheme adopted by the invention is as follows:

the towline link for the robot cable comprises two link plates which are arranged in parallel, wherein the two link plates can be connected with each other through a cover plate to form an accommodating annular structure for placing the cable; the link plate comprises a first connecting part and a second connecting part, the first connecting part and the second connecting part are stacked and connected into a whole through the mutual connecting end parts of the first connecting part and the second connecting part, a buckle is arranged on the first connecting part, and a clamping hole is arranged on the second connecting part; the buckle and the clamping hole are respectively used for being matched and connected with the clamping hole and the buckle on the adjacent connected link plate so as to form the drag chain capable of continuously extending.

Due to the adoption of the structure, one end part of the first connecting part and one end part of the second connecting part are connected into a whole through the overlapped structural form, the structure similar to the Z shape is formed, the connection of the adjacent tow chain links can be realized through the extrusion force by the first connecting part and the second connecting part, and under the structural restoring force of the first connecting part and the second connecting part and the laminating and installing effect of the first connecting part and the second connecting part on the other tow chain links, the phenomenon that the tow chain links are easy to fall off can be effectively placed.

According to the towline link for the robot cable, the connecting end parts of the first connecting part and the second connecting part are of cambered surface structures which are respectively a cambered surface one and a cambered surface two; the other end of the first connecting part and the other end of the second connecting part are both arc-shaped end parts, and the arc-shaped end parts can be matched with arc-shaped structures on the adjacent connecting plates to rotate.

Further, the length and the thickness of the first connecting part and the connecting part are the same.

Furthermore, the buckle is arranged on the outer side of the first connecting part, and the second connecting part is stacked on the outer side wall of the first connecting part; the height of the buckle is larger than or equal to the thickness of the second connecting part.

Furthermore, the buckle is clamped with a clamping hole on a connecting part II of the adjacent connected drag chain link by inwards extruding the connecting part I.

By adopting the structure, the arc-shaped end part on the connecting part can be attached to the corresponding arc surface to rotate in the rotating process, so that the rotating action before the drag chain section is more stable while the compact design of the structure is ensured, and the mutual restriction action of parts in the rotation can be avoided, so that the drag chain formed by the utility model has good flexibility in the bending process; the buckle sets up in the outside of connecting portion one to make and run through to the outside in card hole through the card hole by the inside wall department of connecting portion two through extrusion connecting portion one, further placing droing between the tow chain section of such structural design, structural connection is simple and stable.

According to the towline link for the robot cable, the edge of the link plate is further provided with the connecting groove for connecting the clamping part of the cover plate.

furthermore, the same side edge parts of the two link plates are fixedly connected through the bottom plate so as to limit the distance between the two link plates.

Further, the distance between the first connecting parts on the two link plates is equal to the width of the cover plate packaging part.

Owing to adopt above-mentioned structure, through the annular space that bottom plate or bottom plate and apron formed the confession cable and pass with the tow chain joint between the link plate for the cable can be settled regularly in this space, avoids the cable to flee out the normal use that influences equipment outside the tow chain easily, maintains good operational environment for machine equipment.

In summary, due to the adoption of the technical scheme, the invention has the beneficial effects that:

1. The towline link for the robot cable has a simple structure and is convenient to install and use;

2. the tow chain formed by the tow chain links has good car playing flexibility;

3. The structural stability is good;

4. The practicability is strong.
