Background technique
In well known technical field, high density polyethylene (HDPE) (HDPE) double-wall corrugated pipe is a kind of with cyclic structure outer wall
With the novel tube of smooth internal walls.Density polyethylene (HDPE) has excellent chemical stability, ageing-resistant and environmental stress resistance
The performance of cracking.Existing bellows is mainly connect by being flared with the mutual socket joint of jackended, and the effect of socket joint connection is good
Roundness that is bad then depending on flaring structure.But the tubing to get off from production line is due to thermal deformation or is squeezed, and is easy to cause
Tubing flaring deforms, and the flaring of deformation increases the difficulty of socket joint connection, leverages construction efficiency, increase economy at
This.Accordingly, it is considered to which a kind of on-deformable flaring structure is very necessary.
Utility model content
The utility model in order to overcome at least one of the drawbacks of the prior art described above, provides a kind of distortion-free bellows
Flaring structure and its plastic pipe structure, in a pipeline enlarging circle provided circumferentially about or the reinforcing rib of multi-turn evagination indent, enhancing
The annular stress-bearing capability of flaring, the deformation for reducing flaring thermal deformation or generating when being squeezed influence, and reduce product defect rate, just
It is connected in tubing socket joint.
In order to solve the above technical problems, the technical solution adopted in the utility model is:
A kind of distortion-free bellow flare structure, the flaring including bellows and positioned at bellows one end, the flaring
Circumferential section, which is equipped with, is used for distortion-free reinforcing rib.Add a circle or multi-turn reinforcing rib in flaring circumference, enhancing flaring annular by
The ability of power weakens the deformation of flaring.
Preferably, the reinforcing rib is ring stiffener.Reinforcing rib is cirque structure, it is ensured that uniform force.
Preferably, the reinforcing rib is in bulge-structure in flaring outer wall, it is in concave inward structure in flaring inner wall.Reinforcing rib exists
It is flared protrusion on outer wall, and the indent on flaring inner wall prevents plastics from shrinking primarily to keeping reinforcing rib monolith thick uniformly
And generate defect.
Preferably, the material of the reinforcing rib is thick uniformly.
Preferably, the thick average material for being equal to flaring of the material of the reinforcing rib is thick.The material of reinforcing rib is thick to be averaged with what is be flared
Material thickness is equal or approximately equal, primarily to tubing is made to reduce shrinking deformation in injection molding.
Preferably, the cross sectional shape of the reinforcing rib is rectangle or semicircle.Shape one of the reinforcing rib in flaring outer wall
As can be rectangle or semicircle.
Preferably, the reinforcing rib and flaring are integrally formed.Reinforcing rib and flaring are integrated extrusion and are cooled and shaped, and are not required to
Additional molding procedure is wanted, economic cost is lower.
A kind of plastic pipe structure using distortion-free bellow flare structure, the plastic pipe structure includes HDPE
Bellows, PP bellows or other plastic pipes connected by flaring socket joint.
Compared with prior art, the utility model has the beneficial effects that the utility model discloses a kind of anti-deformations
Bellow flare structure and its plastic pipe structure, the flaring including bellows and positioned at bellows one end, flaring circumference
The reinforcing rib of upper one circle of setting or multi-turn evagination indent, enhances the annular stress-bearing capability of flaring, reduce flaring thermal deformation or by
The deformation generated when extruding influences, and reduces product defect rate, connects convenient for tubing socket joint, and economic cost is lower, is conducive to wide
General application.Meanwhile the distortion-free bellow flare structure can be applied to HDPE bellows, PP bellows or other pass through flaring
The plastic pipe of socket joint connection.
Detailed description of the invention
Fig. 1 is the utility model overall structure sectional view.
Wherein, 1 bellows, 2 flarings, 3 reinforcing ribs.
Specific embodiment
The attached figures are only used for illustrative purposes and cannot be understood as limitating the patent；In order to better illustrate this embodiment, attached
Scheme certain components to have omission, zoom in or out, does not represent the size of actual product；To those skilled in the art,
The omitting of some known structures and their instructions in the attached drawings are understandable.Being given for example only property of positional relationship is described in attached drawing
Illustrate, should not be understood as the limitation to this patent.
The same or similar label correspond to the same or similar components in the attached drawing of the utility model embodiment；It is practical at this
In novel description, it is to be understood that if having the orientation or position of the instructions such as term " on ", "lower", "left", "right" " length " " short "
Setting relationship is to be based on the orientation or positional relationship shown in the drawings, and is merely for convenience of describing the present invention and simplifying the description, and

Those of ordinary skill for, can understand the concrete meaning of above-mentioned term as the case may be.
Below by specific embodiment, and in conjunction with attached drawing, the technical solution of the utility model work is further specifically retouched
It states:
Embodiment 1
As shown in Figure 1, present embodiments provide a kind of distortion-free bellow flare structure, including bellows 1 and it is located at
The flaring 2 of 1 one end of bellows, 2 circumferential sections of flaring are equipped with the reinforcing rib 3 for distortion-free annular, the present embodiment reinforcing rib 3
Cross sectional shape be rectangle, in the case of other, the cross sectional shape of reinforcing rib 3 can also be semicircle.
Specifically, reinforcing rib 3 is in bulge-structure being flared 2 outer walls, is in concave inward structure being flared 2 inner walls, primarily to
Keep 3 monolith of reinforcing rib thick uniformly, meanwhile, the thick average material for being equal to flaring 2 of the material of reinforcing rib 3 is thick, effectively prevent material thickness ununiformity
The plastics shrink phenomenon of generation.
Specifically, reinforcing rib 3 and flaring 2 are integrally formed.Reinforcing rib 3 and flaring 2 are integrated extrusion and are cooled and shaped, and do not need
