Abstract
The utility model provides a wear-resisting protective tube which adopts a protective tube structure of which the frictional resistance of the inner wall is small. The integral wear-resisting protective tube adopts a cylindrical tubular structure; the pipe wall adopts a multi-layer structure; the pipe wall of the protective tube is formed by combining an outer plastic layer, a metal steel wire layer, an inner plastic layer and a wear-resisting layer from outside to inside; the frictional resistance of the wear-resisting layer is smaller than that of the inner plastic layer; the thickness of the wear-resisting layer is smaller than that of the inner plastic layer; the wear-resisting layer and the inner plastic layer are in no clearance fit. Further, the metal steel wire layer is formed by winding circular steel wires. Furthermore, the wear-resisting layer and the inner plastic layer are matched through no clearance hot melting bonding.
Description
Technical field
The utility model relates to auto parts and components, is specifically related to the pillar assembly on the automobile guy cable.
Background technique
The individual parts that have on the automobile guy cable are called pillar, its conventional construction as shown in Figure 3, Figure 4, tradition pillar structure is by three layers of pipe, be outer plastic layer 1, metal steel wire floor 2 and inner plastic layer 3, because the material that usually adopts of inner plastic layer 3 is PE, its shortcoming is that intensity is guaranteed and surface friction drag is relatively high, if the whole employing PTFE of inner plastic layer 3, its cost is higher again, is unfavorable for promoting widely and using.
Summary of the invention
The utility model provides a kind of wear-resistance protective pipe inwall surface friction drag little pillar structure for above-mentioned the deficiencies in the prior art.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of wear-resistance protective pipe, and integral body is cylindrical body tubulose structure, tube wall is multi-layer structure, the outer plastic layer of pillar tube wall by arranging from outside to inside, the metal steel wire floor, inner plastic layer, wearing layer combines; The friction factor of described wearing layer is less than the friction factor of inner plastic layer, and the thickness of described wearing layer is less than the thickness of inner plastic layer, and wearing layer and inner plastic layer are that gapless cooperates.
Further be: above-mentioned metal steel wire floor is twined by round wire and forms.
Further be: above-mentioned wearing layer and inner plastic layer cooperate by the gapless hot melt adhesion.
The beneficial effects of the utility model are:
The utility model pillar pillar has more in the past increased wearing layer, and wearing layer also is plastic material.The inner plastic layer material is PE, has higher intensity and toughness, and wearing layer is the very little PTFE of friction factor, and inner plastic layer is that gapless cooperates with wearing layer, both guarantee the intensity of this pillar after two kinds of plastic layers cooperate, obtained again the good higher problem of friction factor that has solved pillar.Because this wearing layer is very thin one deck, its manufacture cost reduced more greatly, and the economic performance of this pillar is improved, and fabricating cost is minimized.Can make the pillar of all size, thereby be widely used.

Description of reference numerals:
The 1-outer plastic layer, 2-metal steel wire floor, 3-inner plastic layer, 4-wearing layer.
Embodiment
Below in conjunction with drawings and Examples the utility model embodiment is described:
Fig. 1, Fig. 2 show a specific embodiment of the present utility model, a kind of wear-resistance protective pipe of the utility model, and integral body is cylindrical body tubulose structure, tube wall is multi-layer structure, the outer plastic layer 1 of pillar tube wall by arranging from outside to inside, metal steel wire floor 2, inner plastic layer 3, wearing layer 4 combines; The friction factor of described wearing layer 4 is less than the friction factor of inner plastic layer 3, and the thickness of described wearing layer 4 is less than the thickness of inner plastic layer 3, and wearing layer 4 and inner plastic layer 3 cooperate for gapless.
The above-mentioned metal steel wire floor 2 of stating is comprised of the round wire winding.
Above-mentioned wearing layer 4 and inner plastic layer 3 cooperate by the gapless hot melt adhesion.
The utility model pillar pillar has more in the past increased wearing layer 4, and wearing layer 4 also is plastic material.Inner plastic layer 3 materials are PE, has higher intensity and toughness, and wearing layer 4 is the very little PTFE of friction factor, and inner plastic layer 3 cooperates for gapless with wearing layer 4, both guarantee the intensity of this pillar after two kinds of plastic layers cooperate, obtained again the good higher problem of friction factor that has solved pillar.Because this wearing layer 4 is very thin one deck, its manufacture cost reduced more greatly, and the economic performance of this pillar is improved, and fabricating cost is minimized.Can make the pillar of all size, thereby be widely used.
The above has done detailed description to the utility model preferred implementation by reference to the accompanying drawings; but the utility model is not limited to above-mentioned mode of execution, and all improvement in the ken that those of ordinary skills were possessed of carrying out as the basis take thought of the present utility model all drop in the protection domain of the present utility model.
Do not break away from design of the present utility model and scope and can make many other changes and remodeling.Should be appreciated that the utility model is not limited to specific mode of execution, scope of the present utility model is defined by the following claims.
