Abstract
The utility model reveals a high-leakproofness corrugated pipe. The high-leakproofness corrugated pipe comprises a corrugated pipe body, wherein the two ends of the corrugated pipe body are provided with a first end part and a second end part respectively, the first end part of the corrugated pipe is connected with the second end part of an adjacent corrugated pipe, and the corrugated pipe body comprises a plurality of corrugated units. The first end part comprises two corrugated units, a sealing mechanism is arranged between the two corrugated units, and the sealing mechanism comprises two or more sealing rings. According to the high-leakproofness corrugated pipe, due to the fact that the two or more sealing rings are arranged, the leakproofness of the corrugated pipe can be prolonged in the using process of the corrugated pipe.
Description
Technical field
The utility model belongs to plastic pipe technical field, relates to a kind of bellows, relates in particular to a kind of high-airtightness corrugated pipe.
Background technique
Buried pipeline underground owing to being deeply buried in (for draining, blowdown, ventilation etc.), needs larger bearing capacity, and bellows is a kind of buried plastic pipe that is widely used in.
Refer to Fig. 1, the structural representation that Fig. 1 is existing bellows.Existing bellows comprises bellows main body 1, and bellows main body 1 comprises some corrugated unit.Between two corrugated unit (low order end in Fig. 1) of bellows main body 1 one end, be provided with seal ring 2 ', the other end is provided with the second end 3; During use, bellows arranges the sealing that cooperatively interacts of one end of seal ring 2 ' and the second end 3 of adjacent corrugations pipe.
As shown in Figure 1, existing seal ring 2 ' only has a slice conventionally, and after sealing circle is damaged, the sealing of bellows is existing problems just.
In view of this, nowadays in the urgent need to designing a kind of new bellows, to overcome the above-mentioned defect of existing bellows.
Model utility content
Technical problem to be solved in the utility model is: a kind of high-airtightness corrugated pipe is provided, can improves the sealing of bellows.
For solving the problems of the technologies described above, the utility model adopts following technological scheme:
A high-airtightness corrugated pipe, described bellows comprises bellows main body, the two ends of bellows main body arrange respectively first end, the second end; The first end of bellows is connected with the second end of adjacent corrugations pipe; Described bellows main body comprises some corrugated unit; Described first end comprises two corrugated unit, between two corrugated unit, is provided with sealing mechanism, and sealing mechanism comprises two or more seal rings.
As a kind of preferred version of the present utility model, described two or more seal ring integrated designs.
As a kind of preferred version of the present utility model, described first end comprises three or three above corrugated unit, and adjacent corrugations shape is respectively equipped with described sealing mechanism between unit.
As a kind of preferred version of the present utility model, described the second end is roughly the cylindrical of hollow, and the external diameter of the corresponding seal ring of the internal diameter of the second end makes the sealing that cooperatively interacts of the second end and seal ring.
As a kind of preferred version of the present utility model, described bellows comprises inwall and the corrugated outer wall of hollow; Between two adjacent corrugated unit of described corrugated outer wall, be provided with at least two stiffening ribs.
As a kind of preferred version of the present utility model, described stiffening rib is hollow structure.
The beneficial effects of the utility model are: the high-airtightness corrugated pipe the utility model proposes, by a plurality of seal rings are set, can improve the sealing in bellows using process.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing sealed type bellows.
Fig. 2 is the structural representation of the utility model bellows.
Fig. 3 is the structural representation of the utility model bellows first end.
Embodiment
Below in conjunction with accompanying drawing, describe preferred embodiment of the present utility model in detail.
Embodiment one
Refer to Fig. 2, Fig. 3, the utility model has disclosed a kind of high-airtightness corrugated pipe, and described bellows comprises bellows main body 1, and the two ends of bellows main body 1 arrange respectively first end 4, the second end 3; The first end 4 of bellows is connected with the second end 3 of adjacent corrugations pipe; Described bellows main body 1 comprises some corrugated unit.
Described first end 4 comprises two corrugated unit, between two corrugated unit, is provided with sealing mechanism 2, and sealing mechanism 2 comprises two or more seal rings.Described two or more seal ring can separatedly arrange, also can integrated design.
Described the second end 3 is roughly the cylindrical of hollow, and the external diameter of the corresponding seal ring of the internal diameter of the second end 3 makes the sealing that cooperatively interacts of the second end 3 and seal ring.
In addition, described bellows comprises inwall and the corrugated outer wall of hollow; Between two adjacent corrugated unit of described corrugated outer wall, be provided with at least two stiffening ribs.Described stiffening rib is hollow structure.
Embodiment two
The present embodiment and embodiment's one difference is, in the present embodiment, described first end 4 can comprise three or three above corrugated unit, and adjacent corrugations shape is respectively equipped with described sealing mechanism between unit.More than 2 groups or 2 groups sealing mechanisms can be set.
In sum, the high-airtightness corrugated pipe the utility model proposes, by a plurality of seal rings are set, can improve the sealing in bellows using process.
Here description of the present utility model and application is illustrative, not wants by scope restriction of the present utility model in the above-described embodiments.Here disclosed embodiment's distortion and change is possible, and for those those of ordinary skill in the art, the various parts of embodiment's replacement and equivalence are known.Those skilled in the art are noted that in the situation that not departing from spirit of the present utility model or substantive characteristics, and the utility model can be with other form, structure, layout, ratio, and realizes with other assembly, material and parts.In the situation that not departing from the utility model scope and spirit, can carry out other distortion and change to disclosed embodiment here.
