Preferably, the material of the inner restrictive coating and external sheath layer is compound PUR polyurethane.

Preferably, the material of the insulating layer is PVC or TPE.

Preferably, the quantity of the conductor is no less than 6.

Preferably, the steel wire is zinc-coated wire, its quantity is no less than 2.

Preferably, the steel wire, which interts, is arranged between the copper wire of copper-wire braided layer.

Preferably, the density of the continuous packing of melamine bubble is not less than 20Kg/m³。

Compared with prior art, the beneficial effects of the utility model are as follows：

The utility model steeps continuous packing in the centrally disposed belting layer and melamine of cable, improves the tight ness rating of structure, protects The rounding, smooth and beautiful of cable appearance is demonstrate,proved, by steel wire, is ensureing that rubber cable has the same of unrivaled pliability When, there is higher tensile strength, prevent cable core break phenomenon, extend service life of the cable under frequent mobile status, carry High security；The utility model has excellent fire resisting, flame-retarding characteristic and electric field shielding effect, and technical maturity, cost is low, is applicable in In lasting bending, mobile towing chain device, there is stable structure, safe.

Brief description of the drawings

Fig. 1 is the structure diagram of the utility model.

In figure：It is 1 inner restrictive coating, 2 external sheath layers, 3 copper-wire braided layers, 4 steel wires, 5 conductors, 6 insulating layers, 7 belting layers, 8 close The continuous packing of amine bubble.

Embodiment

The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work All other embodiments obtained, shall fall within the protection scope of the present invention.

Referring to Fig. 1, the present embodiment provides a kind of flexible single drag chain cable, including the continuous packing 8 of melamine bubble, it is described close The continuous outside of packing 8 of amine bubble is coated with belting layer 7, and the outside of belting layer 7 is provided with inner restrictive coating 1, the belting layer 7 and interior Circumference uniform distribution conductor 5 between restrictive coating 1, the outside of conductor 5 are coated with insulating layer 6, and the outside of inner restrictive coating 1 is coated with Copper-wire braided layer 3, steel wire 4 is provided with the copper-wire braided layer 3, and the outside of copper-wire braided layer 3 is coated with external sheath layer 2.

Wherein, the material of the inner restrictive coating 1 and external sheath layer 3 is compound PUR polyurethane；The material of the insulating layer 6 For PVC or TPE；The quantity of the conductor 5 is no less than 6；The steel wire 4 is zinc-coated wire, its quantity is no less than 2；It is described Steel wire 4 is interspersed to be arranged between the copper wire of copper-wire braided layer 3；The density of the continuous packing 8 of melamine bubble is not less than 20Kg/m³。

The present embodiment is using inner restrictive coating 1, external sheath layer 2, copper-wire braided layer 3, steel wire 4, conductor 5, insulating layer 6, band The combination of layer 7 and the continuous packing 8 of melamine bubble, steeps silk floss by the centrally disposed belting layer 7 and melamine of the conductor 5 in annular arrangement and fills out Bar 8, belting layer 7 and the continuous integral-filled cable center gap of packing 8 of melamine bubble are filled, the tight ness rating of structure is improved, ensures cable It is the rounding of appearance, smooth and beautiful, the anti-flammability of cable is improved, by the steel wire 4 set in copper-wire braided layer 3, is ensureing rubber While skin cable has unrivaled pliability, there is higher tensile strength, prevent cable core break phenomenon, extend cable Service life, improves security；Belting layer 7 coats the continuous packing 8 of melamine bubble, the continuous packing 8 of melamine bubble have it is heat-resisting, fire-retardant, The advantages that rebound degree is high, not only increases the fire resistance of cable, and can keep the construction of cable, improve the steady of the construction of cable It is fixed, and buffering is provided for the bending of the conductor 5 and insulating layer 6 of cable, cable abrasion is reduced, extends cable service life；In short, The flexible single drag chain cable of the present embodiment, has excellent fire resisting, flame-retarding characteristic and an electric field shielding effect, technical maturity, into This is low, suitable for lasting bending, mobile towing chain device, has the advantages that stable structure, safe.
