CN2275538Y - Plastic protecting sleeve for operating wire of motor-vehicle - Google Patents

Abstract

The utility model relates to a plastic protective sleeve for an operating wire of a motor-vehicle, which comprises a metal hose 2 and an outer wrapped layer 1 out of the metal hose 2. The utility model is characterized in that the metal hose is spaced, coiled, wound and shaped by two flat yarns 3 and 4 with different shapes. Hence, the surface smoothness of the existing hose is destroyed by the utility model, the gap among each circle is enlarged, the movable volume of an outer section is increased when the hose is bent, the utility model can be bent at will without deformation under the action of outer force, the work of a shaft core is raised till the work is not changed through following the multiple curvatures of the work, and thereby, the normal work state for the shaft core in the hose is ensured.

Description

Self-propelled vehicle control wire plastic jacket pipe

The utility model relates to a kind of automobile-use annex, relates in particular to a kind of self-propelled vehicle control wire plastic jacket pipe.

In motor bike, automobile operation line family, used mileometer soft shaft, rotating speed line generally all adopt the monofilament protecting pipe, and promptly the metallic hose of protecting pipe is by a flat filament winding shaping.In use we find: because this monofilament tube-surface planeness is good, gap little (almost nil) between each circle, flexible pipe elasticity is big, work under control wire whip situation, axle core work liter reaches and can change with its many curvatures, thereby has influenced the normal operation of axle core in flexible pipe.

The purpose of this utility model is to provide the big self-propelled vehicle control wire plastic jacket pipe in gap between each circle of a kind of metallic hose.

The utility model is achieved in that a kind of self-propelled vehicle control wire plastic jacket pipe, comprises metallic hose and its outer surrounding layer, is characterized in that metallic hose is to be reeled at interval by two difform flat filaments to form.

The utility model can be achieved in that also described two difform flat filaments are triangle wire and halfround wire.

Compare with existing plastic jacket pipe, the utility model has been broken the custom of a flat filament winding shaping in the past, employing is wound into a flexible pipe at interval by two difform flat filaments, destroyed the surface evenness of original flexible pipe, increased the gap between each circle, made the movable volume increase in flexible pipe outer cross section when the bending, be subjected under the external force effect, can be crooked arbitrarily and indeformable, a core work liter is reached do not change, thereby guaranteed the normal working of axle core in flexible pipe with its many curvatures.

Fig. 1 is an integral structure scheme drawing of the present utility model.

Fig. 2 is the A-A cutaway view of Fig. 1.

Below in conjunction with accompanying drawing the utility model being done one describes in detail:

Shown in Fig. 1-2, the utility model be with the 70# steel wire by the hard alloy roller, produce triangular shape flat filament and semicircle flat filament, then these two flat filaments are wound into metal mariages flexible pipe at interval, outside the mariages pipe, be coated with shoe-PVC cladding again and get final product.

Claims (2)

1, a kind of self-propelled vehicle control wire plastic jacket pipe, comprise metallic hose (2) with and outer surrounding layer (1), it is characterized in that metallic hose (2) is by two difform flat filaments (3), (4) coiling and molding at interval.

2, a kind of self-propelled vehicle control wire plastic jacket pipe according to claim 1 is characterized in that flat filament (3), (4) are respectively triangle wire and halfround wire.
