Abstract
The utility model discloses a high strength winding internal -rib bellows, including inner wall layer and outer wall layer, inner wall layer is the planomural face, outer wall layer surrounds in the inner wall layer outside with the heliciform, it packs the bed of material to be provided with " chevron shape " between inner wall layer and the outer wall layer. The utility model discloses it packs the bed of material to have increased by one " chevron shape " outside and between the wall layer at inner wall layer for outer wall layer receives external force when extrusion owing to pack the support of the bed of material, is difficult for receiving the damage or is out of shape, has both played strengthening effect, plays the cushioning effect of power again, has increased intensity, greatly reduced the effort of external force to pipe inner wall, make the resistance to compression of bellows with better function, increased the ring rigidity of tubular product on the whole, improved life.
Description
Technical field
This utility model relates to tubing field, specifically, relating to a kind of high intensity and being wound around internal-rib corrugated tube.
Background technology
At present, domestic commonly use large-diameter steel-plastic corrugated tube, mainly some double-wall corrugated pipes and steel plastic strip
Water pipe, double-wall corrugated pipe is a kind of novel tube with circulus outer wall and smooth internal walls, has heatproof
The advantage such as property is strong, resistance is little, flow is big, steel plastic drain pipe has not easy to leak, good fluidity, use longevity
The advantages such as life is long.But above two corrugated tube of the prior art in use has a disadvantage in that
Double-wall corrugated pipe is because being limited by mould, and ring stiffness is relatively low；Although steel plastic drain pipe ring stiffness is high, but not
Being in place of foot that the corrosive nature of steel is poor, steel band is once fragile by corrosion, thus affects the use of pipeline,
The additionally moulding process of steel plastic drain pipe also relative complexization.
Summary of the invention
In place of this utility model is in order to avoid shortcoming and defect present in above two tubing, it is provided that a kind of
Reasonable in design, security performance is high, operates with very convenient, low cost, the most perishable, operation safety
A kind of high intensity is wound around internal-rib corrugated tube.
For solving the problems referred to above, this utility model be the technical scheme is that
A kind of high intensity is wound around internal-rib corrugated tube, including inner wall layer and outer wall layer, it is characterised in that in described
Parietal layer is planomural face, and described outer wall layer is spirally looped around outside inner wall layer, described inner wall layer and outer wall layer
Between be provided with " herringbone " fill the bed of material.
Further, a fulcrum of the described filling bed of material wherein one end is connected with outer wall layer, the other end
Two fulcrums are connected with inner wall layer.
Further, between described inner wall layer and outer wall layer, in addition to filling the bed of material, remainder is cavity structure.
Further, the cross section of described outer wall layer is arc, is designed as rounded feature at its convex outer surfaces.
Further, described inner wall layer, outer wall layer and the filling bed of material are made by PE material.
This utility model improves the integral loop rigidity of corrugated tube, adds intensity, and the impact to external force is played
Cushioning effect, resistance to compression effect is more notable, simple and beautiful structure, the life of the most Wrapping formed technology tubing
Produce and manufacture.
This utility model is embodied in: this corrugated tube adds " a people between inner wall layer and outer wall layer
Font " fill the bed of material so that supported due to the filling bed of material when outer wall layer is extruded by external force, be not easily susceptible to damage
Wound or deformation, both played reinforcement effect, and played again the cushioning effect of power, add intensity, greatly reduce
The external force active force to pipe material inner wall, the resistance to compression making corrugated tube is with better function, adds the ring of tubing on the whole
Rigidity, improves service life.It addition, after adding " herringbone " filling bed of material, when tubing is by environment
Factor affects and can also play cushioning effect when generation is expanded with heat and contract with cold.
The utility model is described in further detail with detailed description of the invention below in conjunction with the accompanying drawings simultaneously.
Accompanying drawing explanation
Fig. 1 is the cross section enlarged diagram that a kind of high intensity of this utility model is wound around internal-rib corrugated tube；
Fig. 2 is the overall structure schematic diagram that a kind of high intensity of this utility model is wound around internal-rib corrugated tube；
Wherein, in figure: 1-inner wall layer；2-outer wall layer；3-fills the bed of material；4-fulcrum；5-cavity.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, to the technical side in this utility model embodiment
Case is clearly and completely described.
As it is shown in figure 1, the utility model discloses a kind of high intensity to be wound around internal-rib corrugated tube, including inner wall layer 1
And outer wall layer 2, described inner wall layer 1 is planomural face, and described outer wall layer 2 is spirally looped around outside inner wall layer 1
Side, is provided with " herringbone " and fills the bed of material 3 between described inner wall layer 1 and outer wall layer 2.
Comparing with the internal-rib corrugated tube of traditional double-wall corrugated pipe and " 1 " font, this utility model one is high
Intensity is wound around internal-rib corrugated tube and internal rib formations is made that further reformed AHP, i.e. described " herringbone "
One fulcrum 4 of the wherein one end filling the bed of material 3 structure is connected with outer wall layer 2, two of the other end
Point 4 is connected with inner wall layer 2, and three fulcrums 4 define a stable triangular structure, when outer wall layer 2
When being extruded by external force, this filling bed of material 3 can effectively play resistance to compression effect, it is to avoid outer wall layer 2 is subject to
To damage or deformation, and then reduce the external force active force to inner wall layer 1, make the resistance to compression function of corrugated tube
Higher, add the ring stiffness of tubing on the whole, improve service life.
It addition, be except the filling outer remainder of the bed of material 3 between this utility model inner wall layer 1 and outer wall layer 2
Cavity 5 structure, after which increasing " herringbone " filling bed of material 3, when tubing is produced by such environmental effects
Cushioning effect can also be played when expanding with heat and contract with cold.
For further prioritization scheme, the cross section of this utility model outer wall layer 2 is arc, and this high intensity twines
Being a sector around the whole cross section of internal-rib corrugated tube, hollow space is separated by " herringbone ", by cross section
It is divided into three parts.It addition, the part of this utility model outer wall layer 2 projection is designed as rounded feature, the most not
The most more attractive, and the pipeline formed is round and smooth, without corner angle, is difficult to incised wound or scratches human body.
For further prioritization scheme, this utility model high intensity is wound around inner wall layer 1 described in internal-rib corrugated tube, outer
Parietal layer 2 and " herringbone " are filled the bed of material 3 and are made by PE material, the most not only increase intensity, also
It is difficult to be corroded.
Above-described this utility model embodiment, is not intended that the restriction to this utility model protection domain.
Any amendment, equivalent and improvement etc. made within spirit of the present utility model and principle, all should wrap
Within being contained in claims of the present utility model.
