Preferably, a connecting rib is arranged between the outer protective layer and the inner protective layer on the outer wall of the bump.

Preferably, the inner diameter of the groove is larger than the outer diameter of the bump.

Preferably, the inner diameter of the first mounting groove and the second mounting groove is larger than the outer diameter of the shielding layer.

Compared with the prior art, the beneficial effects of the utility model are that: according to the bending-resistant towline cable, the outer protective layer, the groove, the inner protective layer and the bump are arranged, so that the bump of the inner protective layer can move in the groove of the outer protective layer, the inertia moment between the inner protective layer and the outer protective layer is increased, the effects of increasing the inertia moment of the protective layer and improving the bending resistance of the protective layer are achieved; through setting up first soft layer, first mounting groove, the soft layer of second, the second mounting groove, can produce the gasbag through first mounting groove and second mounting groove mutually supporting, at the in-process of buckling, frictional force reduces between cable conductor and the soft layer, reach the effect that makes the more easy bending of tow chain cable, make this resistant crooked tow chain cable, moreover, the steam generator is simple in structure, the cost of manufacture is low, can effectively increase the resistant bending property ability of tow chain cable, the service life of improvement tow chain cable, and economic loss is reduced.

Drawings

Fig. 1 is a structural cross-sectional view of a bending-resistant towline cable according to the present invention;

in the figure: the cable comprises an outer protective layer 1, a groove 2, an inner protective layer 3, a bump 4, a waterproof protective sleeve 5, a first soft layer 6, a first mounting groove 7, a second soft layer 8, a second mounting groove 9, a cable conductor 10, a conductor structure 11, an insulating layer 12, a shielding layer 13, a nylon core 14 and a connecting rib 15.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1, the present invention provides a technical solution: the utility model provides a resistant crooked tow chain cable, including outer inoxidizing coating 1, 1 inside recess 2 that is equipped with of outer inoxidizing coating, inoxidizing coating 3 in 1 internally connected with of outer inoxidizing coating, install lug 4 on the outer wall of interior inoxidizing coating 3, lug 4 sets up inside

recess

2, 3 internally connected with water proof protection cover 5 of interior inoxidizing coating, 5 internally mounted of water proof protection cover has first soft layer 6, it is isosceles triangle-shaped and is equipped with first mounting groove 7 on 6 outer walls of first soft layer, it has second soft layer 8 to be located 6 internally connected with of first soft layer, it is equipped with second mounting groove 9 to be isosceles triangle-shaped on 8 inner walls of second soft layer, install cable conductor 10 between second mounting groove 9 and the first mounting groove 7, cable conductor 10 inside is equipped with conductor structure 11, conductor structure 11 external connection has insulating layer 12, insulating layer 12 externally mounted has shielding layer 13, the inside nylon core 14 that is equipped with of second soft layer 8.
