China Patent No. is ZL 201220119995.X, and the internal-rib of entitled a kind of band and preparation thereof strengthens spiral to be twined
Patent around tubing discloses a kind of band, including panel, arc body and stud, described arc body be positioned at panel outside and
A cavity is formed, in described stud cavity between arc body and panel and by cavity one between described panel and arc body
Being divided into two, the dual-side of described panel is clinch.The described panel in band, arc body and stud is through being once extruded into
Type.Tubing body is the tubular body formed through winding happy and harmonious welding by described band, and described arc body is at tubing body
Outside forms outer bellows-shaped, and is connected to pipe joint at the two ends plastic welding of tubing body.
The internal-rib of above-mentioned band and preparation thereof strengthens spiral winding tubing and possesses following defect:
1, it is the band of band hollow and overlap edge due to extrusion molding, the when of causing producing band in cavity
Heat cannot discharge, and clinch and the stud of adding both sides need molding, so the speed producing this band can be very slow, and nothing
Method realizes real benefit.
2, being first preforming due to band, then the both sides of the band of cold conditions overlap the tubing being welded into, tubing overlaps
Portion is the weakest place and is the outside being exposed at tubing, and climate temperature, the change transported and install impact very greatly, overlap
Portion's hot strength is inadequate, it is easy to fracture, ripple is spring-like.
China Patent No. is: 201110121186.2, entitled internal rib reinforcing outer ripple type plastic twining structured wall pipe
And the patent of manufacture method discloses a kind of internal-rib and strengthens ripple type plastic winding structural wall tube, this tubing is to be had by both sides
The plastic shaped band having the tubular lobes including cavity is helically wound and forms tubing body through melten gel fusion, with
Two cavities adjacent to each other between the adjacent plastic shaped band that spiral way is wound around form hollow after fusion and strengthen
Muscle, and fusion position forms upright enhancing internal-rib in the middle part of hollow reinforced rib, described tubing body includes cylindrical wall, spiral shell
Rotation is looped around hollow reinforced rib thereon and is positioned at the enhancing internal-rib being perpendicular to tube wall of hollow reinforced rib, this enhancing internal-rib
Described hollow reinforced rib is divided into two cavities arranged side by side, and the faying face of fusion is positioned at this enhancing internal-rib.This tubing be by
Both sides have the plastic shaped band of the tubular lobes including cavity and are helically wound and are formed, with spiral shell through melten gel fusion

[detailed description of the invention]
Below by specific embodiment, a kind of plastics reinforcement of the present invention is wound around corrugated tube to make the most in detail
Describe.
As shown in Figure 1 and Figure 2, a kind of plastics reinforcement is wound around corrugated tube, including tubing tail band 6 and plastic material, plastic material
Being spirally wound on the outside of tubing tail band 6, form outer bellows-shaped, described plastic material includes body 1 and the stud 2 of hollow,
For coextru-lamination molding between described body 1 and stud 2.Described body 1 is isoceles triangle body or isosceles trapezoid body, at this
Being isoceles triangle body in embodiment, described stud 2 is I shape, and its upper/lower terminal is respectively arranged with fixing groove 3 and lower solid
Determining groove 4, the shape of upper fixing groove 3 and lower fixing groove 4 is in semicircle in the present embodiment, wherein upper fixing groove 3 and lower fixing groove 4
Shape can also be other shapes such as dove-tail, belong to the protection category of the present invention.Described stud 2 is positioned in body 1
And the cavity within body 1 is divided into two, the top of body 1 is arc-shaped, when body is isosceles trapezoid body, body 1
Liang Ge angle, top is all with arc transition.Angle a at the base angle of body 1 is between 60 °～80 °.
Preferably, described stud 2 is provided with longitudinal through hole 5, thus reduces the meter Chong of corrugated tube, and
Linear velocity during production can be made to be improved.The arrangement mode in the pass of through hole 5, hole count and hole the most specifically limits in this programme
Fixed, belong to the protection category of the present invention.
Preferably, described tubing tail band 6 is to be wound around, by the base band of strip, the tubular body that also welding is formed, described
Bottom plastic material, fusion mutually hot with base band junction is wound around compound, and the two ends of tubing tail band 6 are respectively provided with pipe joint, wherein
Pipe joint is bellmouth and the socket of electrified heating.
Preferably, the middle part fusion mutually hot with base band welded side seam 7 bottom described plastic material.Its plastic material
The middle part fusion mutually hot with base band welded side seam 7 of bottom is wound around, thus the most hot compound with the weakness of corrugated tube
Molding, substantially increases the intensity of corrugated tube and axial pulling capacity.
Preferably, the both sides of described base band use the cross structure overlapped up and down.Base band is made by cross structure
Connect when being wound around also welding relatively reliable, and ensure that the flatness on base band surface.
When manufacturing, its stud 2 first molding, it is thus possible to determine stud 2 according to the ring stiffness needed for corrugated tube
Width, thus ensure the ring stiffness of corrugated tube, stud 2 and body 1 phase coextru-lamination molding form plastic material, are not only beneficial to
Distributing of heat, moreover it is possible to be greatly improved extrusion speed.Its stud 2 is I shape, and its upper/lower terminal is respectively arranged with solid
Determine groove 3 and lower fixing groove 4.When plastic material and stud 2 use commaterial, both can realize stably fusing, even if
When plastic material and stud 2 use different materials, due to upper fixing groove 3 and the existence of lower fixing groove 4, also can guarantee that both energy
Reliably connect, will not collapse because of by torsion when spiral winding it is thus possible to be effectively prevented plastic material.Shaped plastics
After material manufacture completes, the base band of strip it is wound around and welding forms tubing tail band 6, and simultaneously by bottom plastic material
Between position fusion mutually hot with base band junction be wound around compound, described plastic material forms outer ripple in the outside of tubing tail band 6
Shape, and bellmouth and the socket of band heating wire it is respectively welded at the two ends of tubing tail band 6, thus form corrugated tube.
The principle of the above embodiments only illustrative the invention and effect thereof, and the enforcement that part is used
Example, not for limiting the present invention；It should be pointed out that, for the person of ordinary skill of the art, creating without departing from the present invention
On the premise of making design, it is also possible to make some deformation and improvement, these broadly fall into protection scope of the present invention.
