Abstract
The utility model provides a kind of anti-deformation protective sleeve of pulling cable, including four-layer structure, innermost layer is plastic inner lining pipe, the second layer is steel wire floor, and third layer is lock ring steel bands layer, and outermost layer is to drape over one's shoulders modeling layer, the groove that restricted wire cut is set is set on the lock ring steel bands layer, it is by groove that the steel wire in steel wire floor is evenly distributed, and be wrapped in outside plastic inner lining pipe, the modeling layer that drapes over one's shoulders is wrapped in outside lock ring steel bands layer.Pass through the structure of the special straight wire without torque and the lock ring steel band with limit, keep protective sleeve of pulling cable stability more preferable, and length is constant when realizing sheath bend under the premise of not increasing cost, and then improve the stability of drag-line, guarantee that the length of protective sleeve of pulling cable is constant, improves precision when drag-line uses.
Description
Technical field
The utility model relates to automobile guy cable manufacturing field more particularly to a kind of anti-deformation protective sleeve of pulling cable.
Background technique
Drag-line is as automobile gear shift, door lock, fuel tank cap, the control drag-line of preceding warehouse lid and the brake of motorcycle, bicycle
Vehicle control line plays critically important effect in vehicle travel process, since the A+B at drag-line both ends is having a size of functional dimension, and
Bracing wire sheath traditional at present is generally pure plastic pipe, reed pipe and its multiple tube, braiding multiple tube tradition raw silk rings multiple tube etc., on
Stating bracing wire sheath can make A+B size is elongated to be shortened by its stress release or deformation, and then the length of bracing wire sheath is caused to be sent out
Changing is unsatisfactory for the use demand of user, and therefore, designing one kind can guarantee that length will not be due to stress release or deformation hair
The raw sheath changed is just particularly important.
Utility model content
In view of the deficiencies of the prior art, the purpose of the utility model is to provide a kind of anti-deformation protective sleeve of pulling cable, pass through spy
The structure of the different straight wire without torque and the lock ring steel band with limit, keeps protective sleeve of pulling cable stability more preferable, and not
Length is constant when realizing sheath bend under the premise of increasing cost.
The utility model provides a kind of anti-deformation protective sleeve of pulling cable, including four-layer structure, and innermost layer is plastic inner lining pipe, and second
Layer is steel wire floor, and third layer is lock ring steel bands layer, and outermost layer is to drape over one's shoulders modeling layer, and restricted wire cut is arranged on the lock ring steel bands layer
The groove set, it is by groove that the steel wire in steel wire floor is evenly distributed, and be wrapped in outside plastic inner lining pipe, it is described to drape over one's shoulders modeling layer packet
It is rolled in outside lock ring steel bands layer.
The plastic inner lining pipe needs the plastic tube of selection according to cooperation, can be round tube, polygonal tube or other moulding
Pipe.
The groove that wire cut is set is limited on the lock ring steel band, is determined according to the stress of its use environment and bending situation
Screw pitch, the not close winding of steel band.
Modeling layer is draped over one's shoulders mainly to shield.
Further improvement lies in that: the steel wire in the steel wire floor is straight wire, and is uniformly distributed outside plastic inner lining pipe, nothing
Spiral winding.
The sheath is raw silk rings pipe, and length variation will not be generated because of bending.
Further improvement lies in that: the groove, using mold roll forming is corresponded to, is limited before steel wire wound after steel wire wound
The groove alignment relative of same root steel wire processed.
Further improvement lies in that: the modeling layer that drapes over one's shoulders also is embedded in steel wire floor in addition to wrapping in lock ring steel bands layer outer layer
In steel wire gap.
Straight wire can according to need slight sliding when sheath bend, can eliminate larger internal stress caused by bending.
The beneficial effects of the utility model are: passing through the special straight wire without torque and the lock ring steel band with limit
Structure, keep protective sleeve of pulling cable stability more preferable, and under the premise of not increasing cost realize sheath bend when length it is constant, into
And the stability of drag-line is improved, guarantee that the length of protective sleeve of pulling cable is constant, improves precision when drag-line uses.

Specific embodiment
In order to deepen the understanding to the utility model, the utility model is made below in conjunction with embodiment further detailed
It states, the present embodiment is only used for explaining the utility model, does not constitute the restriction to scope of protection of the utility model.
It can be seen that, most of in present protective sleeve of pulling cable is all one of these structures in from Fig. 2 to Fig. 5, from upper
It states in structure it can easily be shown that the length of protective sleeve of pulling cable can be due to stress release or change when protective sleeve of pulling cable bends
Shape changes.
As shown in Figure 1, present embodiments providing a kind of anti-deformation protective sleeve of pulling cable, including four-layer structure, innermost layer are plastics
Internal lining pipe 1, the second layer are steel wire floor 2, and third layer is lock ring steel bands layer 3, and outermost layer is to drape over one's shoulders modeling layer 4, on the lock ring steel bands layer 3
The groove 5 that restricted wire cut is set is set, it is by groove 5 that the steel wire in steel wire floor 2 is evenly distributed, and it is wrapped in plastic inner lining
Outside pipe 1, the modeling layer 4 that drapes over one's shoulders is wrapped in outside lock ring steel bands layer 3.
Modeling layer is draped over one's shoulders mainly to shield.Steel wire in the steel wire floor 2 is straight wire, and outside plastic inner lining pipe 1
Even distribution, no spiral winding.The sheath is raw silk rings pipe, and length variation will not be generated because of bending.The groove 5 steel wire around
Using mold roll forming is corresponded to before system, 5 alignment relative of groove of same root steel wire is limited after steel wire wound.It is described to drape over one's shoulders modeling layer 4
In addition to wrapping in 3 outer layer of lock ring steel bands layer, also it is embedded in the steel wire gap of steel wire floor 2.
Straight wire is slightly slided as needed when sheath bend, eliminates larger internal stress caused by bending.By special
The structure of straight wire without torque and the lock ring steel band with limit, keeps protective sleeve of pulling cable stability more preferable, and is not increasing
Length is constant when realizing sheath bend under the premise of cost, and then improves the stability of drag-line, guarantees the length of protective sleeve of pulling cable not
Become, improves precision when drag-line uses.
