Abstract
The utility model relates to a kind of flexible pipe, it is for improving the pliability of flexible pipe, concrete technological scheme is: a kind of flexible pipe, comprise body, the sidewall of body is double layer construction, comprise skin and internal layer, skin is fixedly connected with by the link of helix structure with internal layer, between skin and internal layer, form along the axially extended spirality cavity of tube wall, the outer surface of body and internal surface are all level and smooth shape, double-deck tube wall makes flexible pipe more firmly wear-resisting, the link of helical structure, strengthen the support force to tube wall, and make to have formed in tube wall a spirality cavity, the existence of cavity strengthens the pliability of flexible pipe, the easier bending deflection of flexible pipe is to adapt to various application, level and smooth outer surface and internal surface can reduce the surface friction drag that flexible pipe is in use encountered.
Description
Technical field
The utility model relates to a kind of flexible pipe.
Background technique
Flexible pipe is the vitals in modern industry, in air conduit and filtration, material processing, on machinery and electric tool and special medical equipment and dental equipment, be widely used, and medical equipment use time due to its particularity, some equipment need often to move and coordinate doctor to implement medical care precess, cable also will often change its position, therefore the protective tube of cable is playing abrasionproof, anti-also need to keep extraordinary pliability when the protective action such as losing, and the pumping tube that dental laboratories uses also needs flexible pipe also to have fabulous pliability in having good conducting effect, otherwise in operating process, be easy to the bottleneck throat of human body to produce injury.
Model utility content
In order to overcome the deficiencies in the prior art, the technical problems to be solved in the utility model is to improve the pliability of flexible pipe.
For addressing the above problem, the technological scheme that the utility model adopts is as follows: a kind of flexible pipe, comprise body, the sidewall of body is double layer construction, comprise skin and internal layer, skin is fixedly connected with by the link of helix structure with internal layer, between skin and internal layer, forms along the axially extended spirality cavity of tube wall, and the outer surface of body and internal surface are all level and smooth shape.
Preferably: in spirality cavity, be provided with spiral supporting element.
Preferably: between internal layer and link, be provided with some along the axially extended linear toughness part of body.
Preferably: the material of linear toughness part is nylon wire or PP silk.
Preferably: the material of link is that hard is moulded muscle.
Compared to existing technology, the beneficial effects of the utility model are: double-deck tube wall makes flexible pipe more firmly wear-resisting, the link of sidewall spiral structure forms a solid os osseum of complete spiral, strengthen the support force to tube wall, and make to have formed in tube wall a spirality cavity, the existence of cavity strengthens the pliability of flexible pipe, the easier bending deflection of flexible pipe is to adapt to various application, the outer surface of tube wall and internal surface are all held in smooth state, it is smooth and easy that smoothly can the ensureing of internal surface managed interior object conducting, reduce both frictions, outer surface smoother can avoid flexible pipe in use to produce resistance not with the external world, especially in the time being used in human body, the pumping tube of for example dentistry, the more convenient operation of level and smooth outer surface, can not produce unnecessary scratch yet.
Brief description of the drawings
Fig. 1 is the profile schematic diagram of the utility model flexible pipe;
Fig. 2 be the utility model flexible pipe side-wall shaft to partial sectional view.
In figure, mark is described as follows:
1, body; 2, link; 3, skin; 4, internal layer; 5, cavity; 6, linear toughness part; 7 supporting elements.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1-2, a kind of flexible pipe, comprise body 1, the sidewall of body 1 is double layer construction, comprise skin 3 and internal layer 4, outer 3 are fixedly connected with by the link 2 of helix structure with internal layer 4, the material of link 2 is preferably the muscle of moulding of hard, spiral connecting piece 2 forms solid spirality os osseum in body 1 sidewall, strengthen the supporting effect to body 1, strengthen its fastness, between skin 3 and internal layer 4, form along the axially extended spirality cavity 5 of body 1 sidewall, this cavity 5 be formed at link and sidewall in, between skin, cavity 5 has strengthened the overall flexibility of body 1, conveniently body 1 being implemented to external force makes its bending deflection adapt to different application occasion, the outer surface of body 1 and internal surface are all level and smooth shape, level and smooth outer surface can avoid flexible pipe to produce resistance with the external world in moving process, such as being stuck, tangle etc., and level and smooth internal surface makes the conducting of flexible pipe more smooth and easy, reduce the frictional force that the interior object of flexible pipe and internal surface produce.
Further improve, in spirality cavity 5, be provided with spiral supporting element 7, supporting element 7 extends axially along body 1 sidewall spirality cavity 5 is interior, and the outer perimeter of supporting element 7 is less than the interior girth of spirality cavity 5, supporting element 7 just has activity space in spirality cavity 5 like this, has both filled spirality cavity 5, increases its load performance, can also be in not affecting the bending deflection performance of flexible pipe, reinforced hose support force radially and the toughness of flexible pipe entirety greatly.
Further improve, be provided with some along the axially extended linear toughness part 6 of body 1 between internal layer 4 and link 2, the material of linear toughness part 6 is preferably nylon wire or PP silk (polypropylene fiber silk).Linear toughness part 6 invests on internal layer 4, has strengthened axial toughness and the fastness of flexible pipe, reduces flexible pipe in use because frequent bending deflection or the external force effect of pullling cause the risk of its fracture.
Above-mentioned mode of execution is only preferred implementation of the present utility model; the scope that can not limit with this utility model protection, the variation of any unsubstantiality that those skilled in the art does on basis of the present utility model and replacement all belong to the utility model scope required for protection.
