Extrusion unit is included, the extrusion unit is mutually closely wound together, and the extrusion unit includes the first cuboid and the second square
Body, first cuboid and the second cuboid are hollow setting；The lower end of first cuboid and the second cuboid connects
It is integrated, first cuboid and the second cuboid point are listed in the left and right ends of extrusion unit, first cuboid and the
Air blanketing is provided between two cuboids, the width of the air blanketing is the 0.8- of the thickness of the right side wall of the first cuboid
1.1 again；Pass through adhesive linkage bonding forming between the two neighboring extrusion unit；Also include enhancement layer, the enhancement layer covers
Cover in the outside of extrusion unit, and the thickness of described enhancement layer is 0.5-1.2 times of the thickness of the madial wall of the first cuboid；
Described extrusion unit, adhesive linkage and enhancement layer is HDPE material；Stainless steel strip is nested with the air blanketing.
As the further improvement of above-mentioned technical proposal, first cuboid is to wait wall thickness component.
As the further improvement of above-mentioned technical proposal, the complete phase of shape of first cuboid and the second cuboid
Together.
The beneficial effects of the utility model are：The utility model extrudes the shape and structure of unit by improving so that extrusion
Unit includes three middle cavitys in the vertical so that the tubing intensity after winding is higher, and is provided with air blanketing
Stainless steel strip, using the good crushing resistance of stainless steel, improve the anti-pressure ability of tubing；Tubing also includes from inside to outside simultaneously
Three layers of wall, wherein two layers of wall for extrusion unit, outermost layer is enhancement layer, and the pipe of three layers of wall construction also substantially increases tubing
Intensity.
Brief description of the drawings
, below will be to needed for embodiment description in order to illustrate more clearly of the technical scheme in the embodiment of the utility model
The accompanying drawing to be used is briefly described.Obviously, described accompanying drawing is part of the embodiment of the present utility model, rather than entirely
Portion's embodiment, those skilled in the art on the premise of not paying creative work, can also obtain it according to these accompanying drawings
His design and accompanying drawing.
Fig. 1 is tubing expansion section view of the present utility model.
Embodiment
Design, concrete structure and caused technique effect of the present utility model are carried out below with reference to embodiment and accompanying drawing
Clearly and completely describe, to be completely understood by the purpose of this utility model, feature and effect.Obviously, described embodiment
It is part of the embodiment of the present utility model, rather than whole embodiments, based on embodiment of the present utility model, the skill of this area
The other embodiment that art personnel are obtained on the premise of not paying creative work, belong to the model of the utility model protection
Enclose.In addition, all connection/annexations being previously mentioned in text, not singly refer to component and directly connect, and refer to can be according to specific reality
Situation is applied, by adding or reducing couple auxiliary, to form more excellent draw bail.Each technology in the invention is special
Sign, can be with combination of interactions on the premise of not conflicting conflict.
Reference picture 1, HDPE stainless steels strengthen three layers of hollow wound pipe, include extrusion unit 1, the extrusion phase of unit 1
Mutually be closely wound together, the extrusion unit 1 includes the first cuboid 11 and the second cuboid 12, first cuboid 11 and
Second cuboid 12 is hollow setting；The lower end of first cuboid 11 and the second cuboid 12 is connected as a single entity, and described first
The cuboid 12 of cuboid 11 and second divides the left and right ends for being listed in extrusion unit 1, the cuboid of the first cuboid 11 and second
Air blanketing 13 is provided between 12, the width of the air blanketing 13 is the 0.8- of the thickness of the right side wall of the first cuboid 11
1.1 again；Pass through the bonding forming of adhesive linkage 2 between the two neighboring extrusion unit 1；Also include enhancement layer 3, the enhancement layer
3 are covered in the outside of extrusion unit 1, and the thickness of described enhancement layer 3 is the thickness of the madial wall of the first cuboid 11
0.5-1.2 times；Described extrusion unit 1, adhesive linkage 2 and enhancement layer 3 is HDPE material；It is nested in the air blanketing 13
There is stainless steel strip 4.When production, extrusion unit is squeezed out from mould first, extrusion unit is just automatic when shaping
The first cuboid and the second cuboid are formd, and the lower end of the first cuboid and the second cuboid closely connects together,
So as to improve shaping after tubing intensity, although the double-wall corrugated pipe of existing market have rectangle extrusion unit wind and
Into, but be simply bonded between extruding unit two-by-two simply by glue, so that overall intensity is little.And this
Three layers of composite intensifying tube of utility model are also wrapped between cuboid two-by-two by when unit formation is extruded, ensuring that
An air blanketing has been included, has gone to improve the ring stiffness of tubing using air blanketing.Meanwhile one layer is covered again outside extrusion unit
HDPE enhancement layer so that tubing is after shaping, by it is interior include outward have three layers of wall, improve the intensity of tubing.Though
So in the prior art, have and cover one layer of HDPE film outside extrusion unit, but change HDPE films and simply play an anti-corruption
The effect of erosion, because its thickness is relatively low, it is difficult to play a part of an enhancing intensity, and enhancement layer of the present utility model is then
Not so, by increasing its thickness, the intensity of tubing is improved while air blanketing is protected.Moreover, also by air
Increase stainless steel strip in interlayer, improve the anti-pressure ability of tubing.
Preferred embodiment is further used as, first cuboid 11 is to wait wall thickness component.First cuboid
11 is identical with the shape of the second cuboid 12.By rationally setting the shape and structure of extrusion unit, extrusion unit is improved
Convenience is produced, and improves the final product quality of extrusion unit.
Better embodiment of the present utility model is illustrated above, but the invention be not limited to it is described
Embodiment, those skilled in the art can also make a variety of equivalent changes on the premise of without prejudice to the utility model spirit
Type or replacement, these equivalent modifications or replacement are all contained in the application claim limited range.
