Description
Technical field
The present invention relates to a kind of bellows, more particularly to a kind of bend in one direction bellows.
Background technology
Bellows, the housing of the cylinder-shaped thin wall wrinkle with multiple transverse waves.Bellows is general by PP, PA or PE material
Material is made, and its is flexible, and displacement or bending can be produced under pressure, axial force, cross force or Moment.Bending through
Cheng Zhong, due to the housing that bellows is the cylinder-shaped thin wall wrinkle with multiple transverse waves, it can bend to any direction.By
In the non-directional flexural property of bellows, it is set to be widely used in the line of Building wood and plant equipment.In addition, with
Bellows is also used for hollow reinforced rib in the production of the outer ripple plastic winding structure wall pipe of empty reinforcement, and it is main former
Because can any characteristic to bending using bellows.The specific production method of the structure-wall pipe material is, in the appearance of bellows
Bread is wrapped up in after melten gel, with spiral winding mode cross-pressure on uncooled winding tube wall, then after the rolling of pinch roller, bellows
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 has the following disadvantages： 1）Because bellows is softer, after being rolled in heated parcel melten gel and by pinch roller, bellows
Section becomes ovalisation, causes the ratio between the width of hollow reinforced rib and height to be 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）Deformed due to the heated of bellows and after rolling, should
The height of the hollow reinforced rib of wall tube material can only achieve the 6 ~ 8% of wall tube material diameter；3）Section is the bellows and tube wall of annular
Contact area it is few, cause both connections weak, reduce the integral bending of wall tube material.
Therefore, it is necessary to a kind of new bellows be provided, to overcome the various shortcomings in above-mentioned technique and structure.
The content of the invention
The purpose of the present invention, is to provide a kind of bend in one direction bellows.
The present invention solve its technical problem solution be：Bend in one direction bellows, it includes integrally formed pipe sheet
Body, the side of the tube body is provided with the flexible wall section that can be stretched, and the opposite side of tube body is provided with the axis along tube body
The flat wall that direction is run through, forms a pipe sheet with middle cavity after round and smooth connection between the flexible wall section and flat wall
Body.
As the further improvement of above-mentioned technical proposal, there is the ripple of plural bar indent evagination on the flexible wall section
Line, the section of the ripple is in one in sharp triangle, obtuse triangle shape, trapezoidal shape, rectangle, toroidal or elliptical shape
Kind.
As the further improvement of above-mentioned technical proposal, the outside wall surface of the flat wall is provided with parallel straight recessed of multiple tracks
Groove, the angle of the longitudinal center line of the straight groove and tube body is acute angle.
As the further improvement of above-mentioned technical proposal, the outside wall surface of the flat wall is provided with knurled recesses.
As the further improvement of above-mentioned technical proposal, the cross section of the flexible wall section for rounding off arc or
The flexible wall section is trapezoidal with the cross section after the round and smooth connection of flat wall.
As the further improvement of above-mentioned technical proposal, the flexible wall section and the cross section after the round and smooth connection of flat wall
For isosceles trapezoid or right-angled trapezium.
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 beneficial effects of the invention are as follows：Tube body in the present invention along the flexible wall section and flat wall being stretched by that can justify
Constituted after slip, based on said structure, when tube body is bent, flexible wall section's stretching, flat wall can only bending and a guiding
Effect, makes the optional position on flat wall be bent along specific direction, also, tube body can only be bent in one direction, realizes
The unidirectional orientation bending of bellows, can be used to produce outer ripple plastic winding structure wall pipe as hollow reinforced rib.

Embodiment
Below in conjunction with the accompanying drawings, the application of the present invention is described in detail.
1~Fig. 2 of reference picture, bend in one direction bellows, it includes 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 side of the tube body is provided with the flexible wall section 1 that can be stretched,
The opposite side of tube body is provided with the flat wall 2 that runs through of axis direction along tube body, the flexible wall section 1 and flat wall 2 it
Between a tube body with middle cavity 3 is formed after round and smooth connection.When tube body is bent, flexible wall section's stretching, flat wall 2
Energy bending simultaneously play the guiding role, and the optional position on flat wall 2 is bent along specific direction, also, tube body can only be along one
Individual direction bending, realizes the unidirectional orientation bending of bellows, can be used to produce outer ripple plastic as hollow reinforced rib
Winding structure wall pipe.
It is further used as preferred embodiment, there is the ripple 10 of plural bar indent evagination on the flexible wall section 1,
