Anti-deformation inhaul cable sheath

Abstract

The invention provides an anti-deformation inhaul cable sheath. The anti-deformation inhaul cable sheath is of a four-layer structure, the innermost layer is a plastic lining pipe, the second layer isa steel wire layer, the third layer is a tight hoop steel layer, and the outermost layer is a plastic wrapping layer; grooves for limiting the positions of steel wires are formed in the tight hoop steel layer; the steel wires in the steel wire layer are uniformly arranged through the grooves, and are wrapped outside the plastic lining pipe; and the plastic wrapping layer is wrapped outside the tight hoop steel layer. Through the special structure comprising the non-torque straight steel wires and limited tight hoop steel, the stability of the inhaul cable sheath is higher, the length when thesheath is bent does not change under the premise without increasing the cost, and then the stability of an inhaul cable is improved, so that the length of the inhaul cable sheath does not change, andthe precision when the inhaul cable is used is improved.

Description

technical field [0001] The invention relates to the field of automobile cable manufacture, in particular to an anti-deformation cable sheath. Background technique [0002] The cable is used as the control cable of the car's gear shift, door lock, fuel tank cover, and front cover, as well as the brake control line of motorcycles and bicycles. It plays an important role in the driving process of the vehicle. Dimension B is the functional dimension, and the current traditional cable sheaths are generally pure plastic tubes, reed tubes and their composite tubes, braided composite tubes, traditional straight wire composite tubes, etc. The above cable sheaths will cause A+ due to stress release or deformation. The length of the B dimension is shortened, which leads to a change in the length of the cable sheath, which does not meet the needs of users. Therefore, it is particularly important to design a sheath that can ensure that the length will not change due to stress release or ...
