Abstract
The utility model discloses a kind of entwining tube, comprise entwining tube body, described entwining tube body being wound with cross section is the first oval pipe crimping, described first pipe crimping scribbles the first coating, described first coating being wound with cross section is the second oval pipe crimping, and described second pipe crimping scribbles the second coating.Disperse the local compression suffered by entwining tube by the first pipe crimping 2 and the second pipe crimping 4, increase the anti-pressure ability of entwining tube, increase working life and the Applicable scope of entwining tube.Cross section is the ratio of the first oval pipe crimping 2 or the second pipe crimping 4 major axis and minor axis when being 2:1, and the dispersion effect of pressure is best.Integrally manufactured technique makes the mechanical strength of entwining tube higher, resistance to compression better effects if.
Description
Technical field
The utility model relates to entwining tube, especially relates to a kind of entwining tube.
Background technique
Entwining tube, large diameter wound pipe, binary wall twisting and pipe, hollow wound pipe be a kind of with high density polyethylene (HDPE) (HDPE, PVC) for raw material, through being wound around a kind of tubing of welding fabrication, due to the moulding process of its uniqueness, can produce the tubing that diameter reaches 3 meters, this is that other production technologies have been difficult to.But the resistance to compression effect of the entwining tube in market is still not good, pays arrears height at some pourings and cannot not be suitable in field.
Model utility content
The purpose of this utility model is to provide a kind of entwining tube, has the advantages that resistance to compression effective mechanical strength high using scope is wide.
In order to achieve the above object, the technological scheme that the utility model provides is: a kind of entwining tube, comprise entwining tube body, described entwining tube body being wound with cross section is the first oval pipe crimping, described first pipe crimping scribbles the first coating, described first coating being wound with cross section is the second oval pipe crimping, and described second pipe crimping scribbles the second coating.
Described cross section is the major axis of oval cross section of the first oval pipe crimping and the ratio of minor axis is 2:1, and described cross section is the major axis of oval cross section of the second oval pipe crimping and the ratio of minor axis is 2:1.
Described entwining tube body and the first coating is integrally manufactured forms, described first coating and the second coating is integrally manufactured forms.
The beneficial effects of the utility model are: the utility model adopts a kind of entwining tube, by comprising entwining tube body, described entwining tube body being wound with cross section is the first oval pipe crimping, described first pipe crimping scribbles the first coating, described first coating being wound with cross section is the second oval pipe crimping, and described second pipe crimping scribbles the second coating.Disperse the local compression suffered by entwining tube by the first pipe crimping 2 and the second pipe crimping 4, increase the anti-pressure ability of entwining tube, increase working life and the Applicable scope of entwining tube.Cross section is the ratio of the first oval pipe crimping 2 or the second pipe crimping 4 major axis and minor axis when being 2:1, and the dispersion effect of pressure is best.Integrally manufactured technique makes the mechanical strength of entwining tube higher, resistance to compression better effects if.
accompanying drawing illustrates:
Fig. 1 is sectional view of the present utility model;
Fig. 2 is the part A enlarged view of sectional view of the present utility model.
Embodiment
Embodiment 1
A kind of entwining tube, comprise entwining tube body 1, described entwining tube body 1 being wound with cross section is the first oval pipe crimping 2, described first pipe crimping 2 scribbles the first coating 3, described first coating 3 being wound with cross section is the second oval pipe crimping 4, and described second pipe crimping 4 scribbles the second coating 5.Disperse the local compression suffered by entwining tube by the first pipe crimping 2 and the second pipe crimping 4, increase the anti-pressure ability of entwining tube, increase working life and the Applicable scope of entwining tube.
Described cross section is the major axis of oval cross section of the first oval pipe crimping 2 and the ratio of minor axis is 2:1, and described cross section is the major axis of oval cross section of the second oval pipe crimping 4 and the ratio of minor axis is 2:1.Cross section is the ratio of the first oval pipe crimping 2 or the second pipe crimping 4 major axis and minor axis when being 2:1, and the dispersion effect of pressure is best.
Described entwining tube body 1 and the first coating 3 is integrally manufactured forms, described first coating 3 and the second coating 5 is integrally manufactured forms.Integrally manufactured technique makes the mechanical strength of entwining tube higher, resistance to compression better effects if.
