Description
Technical field
The present invention relates to a kind of corrugated tube, more particularly to a kind of compound bending corrugated tube.
Background technology
Corrugated tube, the housing of the cylinder-shaped thin wall wrinkle with multiple transverse waves.Corrugated tube is typically by PP, PA or PE material
Material is made, and which has elasticity, can produce displacement or bending under pressure, axial force, cross force or Moment.Bending through
Cheng Zhong, due to the housing that corrugated tube is the cylinder-shaped thin wall wrinkle with multiple transverse waves, which can be bent to any direction.By
In the non-directional flexural property of corrugated tube so as to be widely used in the line of Building wood and plant equipment.In addition, in having
Corrugated tube is also adopted by the production of the outer ripple plastic winding structure wall pipe of empty reinforcement for hollow reinforced rib, and which is mainly former
Because can arbitrarily to the characteristic of bending using corrugated tube.The concrete production method of the structure-wall pipe material is, in the appearance of corrugated tube
After bread wraps up in melten gel, with spiral winding mode cross-pressure on uncooled winding tube wall, then after the rolling of pinch roller, corrugated tube
And melten gel and tube wall are fused together, the outer ripple plastic winding structure wall pipe with hollow reinforced rib is formed.However,
This technique is suffered from the drawback that： 1）Due to corrugated tube softer, in the parcel melten gel after being rolled by pinch roller of being heated, corrugated tube
Section becomes ovalisation, causes the ratio between the width of hollow reinforced rib and height more than 1, reduces outer ripple plastic winding
The ring stiffness of structure-wall pipe material, reduces the integral bending of wall tube material；2）Due to deforming after being heated and roll of corrugated tube, should
The height of the hollow reinforced rib of wall tube material can only achieve the 6 ~ 8% of wall tube material diameter；3）Corrugated tube and tube wall of the section for annular
Contact area few, cause both connections weak, reduce the integral bending of wall tube material.
Therefore, it is necessary to a kind of new corrugated tube is provided, to overcome the various shortcomings in above-mentioned technique and structure.
Content of the invention
The purpose of the present invention, is to provide a kind of compound bending corrugated tube.
The present invention solves the solution of its technical problem：Compound bending corrugated tube, it include integrally formed pipe sheet

The first reinforcement that axis direction runs through.
As the further improvement of above-mentioned technical proposal, first reinforcement to flexible wall section be provided with and
The second relative reinforcement of one reinforcement.
As the further improvement of above-mentioned technical proposal, there is on the flexible wall section ripple of plural bar indent evagination
Stricture of vagina, the section of the ripple are in sharp triangle, obtuse triangle shape, trapezoidal shape, rectangle, toroidal or elliptical shape one
Kind.
Used as the further improvement of above-mentioned technical proposal, the width of first reinforcement is equal to or less than the second reinforcement
Width.
Used as the further improvement of above-mentioned technical proposal, the cross section of the flexible wall section is circular, oval, rectangle
Or trapezoidal middle one kind.
Used as the further improvement of above-mentioned technical proposal, the cross section of the flexible wall section is isosceles trapezoid or right angle ladder
Shape.
Used as the further improvement of above-mentioned technical proposal, the angular range that the flexible wall section can bend is 0 ~ 180 °.
Used as the further improvement of above-mentioned technical proposal, the material of the tube body is PE, PP, EVA, PVC or ABS material
Material.
The invention has the beneficial effects as follows：The lateral wall of the flexible wall section in the present invention is provided with the axis direction along tube body
The first reinforcement for running through, based on said structure, due to arbitrarily can not bending for the first reinforcement, therefore flexible wall section can not be to
Any direction bend, can only bend along specific direction, the first reinforcement to flexible wall section on be provided with first add
After the second relative reinforcement of strong muscle, under the common guide effect of the first reinforcement and the second reinforcement, flexible wall section is only
Can bend along the rightabout of specific one direction and/or the specific direction, it is achieved that the bidirectional oriented bending of corrugated tube, can
To be used for producing outer ripple plastic winding structure wall pipe as hollow reinforced rib.

Specific embodiment
Below in conjunction with the accompanying drawings, the application of the present invention is described in detail.
With reference to Fig. 1～Fig. 2, compound bending corrugated tube, it include integrally formed tube body, and the material of the tube body is modeling
Material, is integrally formed or injection moulding integrated molding by extruding, and the tube body is provided with the flexible wall section 1 that can be stretched, described
The lateral wall of flexible wall section 1 is provided with the first reinforcement 20 that the axis direction along tube body runs through.
Be further used as preferred embodiment, first reinforcement 20 to flexible wall section be provided with and first
The second relative reinforcement 21 of reinforcement 20.
The lateral wall of flexible wall section is provided with the first reinforcement 20 that the axis direction along tube body runs through, based on above-mentioned knot
Structure, due to arbitrarily can not bending for the first reinforcement 20, therefore flexible wall section can not be bent to any direction, can only be along specific
Direction bend, the first reinforcement 20 to flexible wall section on be provided with second reinforcement 21 relative with the first reinforcement 20
Afterwards, under the common guide effect of the first reinforcement 20 and the second reinforcement 21, flexible wall section can only be along specific one side
To and/or the specific direction rightabout bending, it is achieved that the bidirectional oriented bending of corrugated tube, can be used as hollow reinforced rib
For producing outer ripple plastic winding structure wall pipe.
It is further used as preferred embodiment, there is on the flexible wall section 1 ripple 10 of plural bar indent evagination,
As interval between adjacent ripple 10, when tube body bends, ripple 10 is stretched, and the section of the ripple 10 is in sharp triangle
One kind in shape, obtuse triangle shape, trapezoidal shape, rectangle, toroidal or elliptical shape.Certainly, the cross sectional shape of ripple 10 is not
The above-mentioned shape for enumerating is only limited to, different moulds can be made and produce different cross section shape according to the actual needs
The ripple of shape.
It is further used as preferred embodiment, the width of first reinforcement 20 is equal to or less than the second reinforcement 21
Width.As the width of the bending strength of material, the first reinforcement 20 and the second reinforcement 21 can not be wide or narrow, mistake
The first wide reinforcement 20 and the second reinforcement 21 can cause the bond strength between reinforcement and ripple to reduce, and in bending
Easily there is Decrepitation Phenomena；The first narrow reinforcement 20 and the second reinforcement 21 can not play a part of to be oriented to orientation.
It is further used as preferred embodiment, the embodiment as shown in Fig. 3 ~ Fig. 6, the flexible wall section's 1 are transversal
