Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings in conjunction with the following detailed description. It should be understood that the description is intended to be exemplary only, and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.

As shown in fig. 1-3, the wear-resistant towline cable with a buffer structure provided by the utility model comprises an outer tube 1 and an inner tube 4, wherein the outer tube 1 and the inner tube 4 are flexible tubes which can be bent and deformed along with the towline, an inner stay bar 5 is arranged at the center of the inner tube 4, and a cable core 6 is coiled on the outer layer of the inner stay bar 5;

the outer cladding of inner tube 4 has woven mesh 3, woven mesh 3 is articulated by crisscross wire, promote the wear resistance of inlayer, be provided with buffer structure 2 in the clearance of woven mesh 3 and outer tube 1, buffer structure 2 includes ball ring 21, spring 22 and ball 23, connect through spring 22 between two adjacent ball ring 21, ball ring 21 is including A crown plate 211 and the B crown plate 212 that the symmetry set up, connect through slipway board 213 between A crown plate 211 and the B crown plate 212, a plurality of ball 23 has been placed in the clearance that the three connects.

In the embodiment, the buffer structure 2 can perform lateral external force buffering and circumferential external force buffering;

as an example of lateral external force damping: the two adjacent ball rings 21 are connected through four groups of springs 22, when the cable is bent, the springs 22 between the adjacent ball rings 21 are deformed and bent by external force to consume the external force, and transverse external force buffering is realized;

as an example of the buffering of the external force in the circumferential direction: the ring plate A211, the ring plate B212 and the slide plate 213 are connected to form a ball ring 23 with an inner cavity, the inner cavity of the ball ring 21 is of an annular structure, external force generated when the cable is bent acts on the ball ring 21, the ball 23 slides in the annular inner cavity under the influence of the external force, the external force is consumed in the sliding process, and external force buffering in the circumferential direction is achieved.
