Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to specific embodiments and the accompanying drawings.

In order to achieve the purpose, the embodiment of the invention provides a flexible towline cable. As shown in fig. 1 to 3, a flexible towline cable includes: a plurality of wires 1, a plurality of connectors 2, and a plurality of balls 3, wherein,

the axes of a plurality of the wires 1 are coplanar;

in some cases, the outer diameters of the plurality of wires 1 may be the same, and thus may be arranged more closely and neatly.

A plurality of connecting piece 2 fixed connection is respectively at the surface of many wires 1, the connecting piece 2 keeps away from its fixed wire 1's one side and is the cambered surface, the radian of cambered surface with wire 1's radian is the same.

In some embodiments, the connector 2 may be fixedly attached to the outer surface of the lead 1 by gluing.

The plurality of spheres 3 are movably connected to the cambered surface.

In some embodiments, the ball 3 may be movably connected to the arc surface in an embedded manner.

The ball 3 is in contact with the adjacent telescopic cable.

When the cable is dragged, because two adjacent wires 1 are connected through the movable ball body 3, the friction force between the two wires 1 is reduced, the uneven stress of the wires 1 caused by the large friction force between the wires 1 is reduced, and the probability that the wires 1 are broken due to pulling is caused under the condition that the wires 1 are used for a long time. Meanwhile, the arrangement of the cambered surface can limit the lead 1, and the phenomenon that the lead 1 is twisted with each other after long-term use is reduced.

In some embodiments, the lead 1 is sequentially provided with a sheath 4 and a wrapping cloth 5 from outside to inside, four core wires 6 are uniformly distributed in the wrapping cloth 5 in an annular shape, a middle tensile wire body 7 is arranged in the middle of each of the four core wires 6, and a side tensile wire body 8 is arranged between two adjacent core wires 6 and the wrapping cloth 5.

Optionally, the core wire 6 includes a core wire 61 and a core insulation layer 62 wrapped outside the core wire 61.

Optionally, the middle tensile wire body 7 includes a kevlar fiber 71 and a centerline body sheath layer 72 wrapped outside the kevlar fiber 71. The Kevlar fiber 71 has good flexibility and can effectively protect the core wire 6 from being damaged.

Optionally, the lateral tensile strand 8 includes a lateral polyester fiber layer 81 and a lateral strand body wrapping layer 82 wrapped outside the lateral polyester fiber layer.

In some embodiments, two limiting portions 83 are symmetrically disposed on the lateral tensile wire body 8, the limiting portions 83 are used for preventing the core wire 6 from moving to the outside, and in the case that there are only four lateral tensile wire bodies 8 on the outside, when the cable is extruded, the core wire 6 may move to the outside of the lateral tensile wire body 8, so that the lateral tensile wire body 8 loses the protection function for the core wire 6. Optionally, spacing portion 83 and the side tensile line body 8 integrated into one piece, spacing portion 83 has a spacing arcwall face, and the radian of spacing arcwall face is the same with heart yearn 6's radian.

In some embodiments, a groove (not shown) is formed on the inner wall of the wrapping cloth 5, and the lateral tensile wire body 8 is located in the groove. The groove can play a limiting role for the tensile wire body 8 on the opposite side, so that the structure in the wrapping cloth 5 is more stable.

In some embodiments, a hollow layer 9 is further provided between the sheath 4 and the wrapping 5. The hollow layer 9 plays a role of isolation, and the moisture-proof effect of the cable is improved.

In some embodiments, the hollow layer 9 is filled with carbon dioxide. After the cable is on fire, the hollow layer 9 is burnt out by the fire, and carbon dioxide in the hollow layer 9 can play a certain fire extinguishing role, so that the safety of the cable in use is improved.
