Abstract
The utility model discloses a kind of plastic helical bellow, comprise by the body of body plastics blank strip spiral winding, described tube wall is provided with spiral helicine stiffening rib, described stiffening rib is the plastic tube be spirally wound on tube wall, described tube wall is bonded with the clad be tightly coated on by described stiffening rib on tube wall, described clad is the clad plastics blank strip be spirally wound on tube wall.The plastic helical bellow of this structure is lightweight, good rigidly, and bearing capacity is strong.
Description
Technical field
The utility model relates to a kind of plastic helical bellow.
Background technique
The plastic tube of overall plastic structural walls, has the advantages such as lightweight, interface quality is high, the life-span is long, corrosion-resistant, easy construction, is widely used in town water supply, draining, the remote engineering such as water delivery and irrigation and water conservancy irrigation because of it.But the ring stiffness of overall plastic tubing is poor, and bearing capacity is weak.
Model utility content
The technical problems to be solved in the utility model is for above-mentioned defect, provides a kind of ring stiffness better, the plastic helical bellow that bearing capacity is high.
For solving the problems of the technologies described above, the utility model provides a kind of plastic helical bellow of following structure, comprise by the body of body plastics blank strip spiral winding, it is characterized in that described tube wall is provided with spiral helicine stiffening rib, described stiffening rib is the plastic tube be spirally wound on tube wall, described tube wall is bonded with the clad be tightly coated on by described stiffening rib on tube wall, described clad is the clad plastics blank strip be spirally wound on tube wall.
Described body plastics blank strip comprises blank strip body, the upper surface of blank strip body is interval with many with the isometric convex tendon of blank strip body, the upper surface of blank strip body is to the upper bonding jumper extending to form thickness outside and be less than blank strip body, the lower surface of blank strip body is to the lower bonding jumper extending to form thickness outside another and be less than blank strip body, and the thickness sum of lower bonding jumper and upper bonding jumper equals the thickness of blank strip body.
Described clad plastics blank strip comprises blank strip main body, and the upper surface of blank strip main body is provided with many ribs isometric with blank strip main body.
The outer wall of described plastic tube is provided with many spaced ring muscle.
Body of the present utility model is provided with the spiral helicine stiffening rib by wound plastic tube, namely stiffening rib is hollow structure, not only can increase the ring stiffness of plastic helical bellow and improve its bearing capacity, and the weight of plastic helical bellow can be reduced, make it have lightweight, that bearing capacity is strong advantage; Be provided with clad outside stiffening rib, what stiffening rib not only can be made to be connected with body is more firm, and can also improve the bearing capacity of plastic helical bellow further.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the cross-sectional configuration schematic diagram of body blank strip;
Fig. 3 is the cross-sectional configuration schematic diagram of clad blank strip;
Fig. 4 is the A portion enlarged view of Fig. 1;
Fig. 5 is the structural representation of plastic tube.
Embodiment
Shown in Fig. 1, plastic helical bellow comprises body 1, described body 1 outer wall is provided with spiral helicine stiffening rib 2, described stiffening rib 2 is for being spirally wound on the plastic tube on body 1 outer wall, described body 1 outer wall is bonded with the clad 3 be tightly coated on by described stiffening rib 2 on body 1 outer wall, described clad 3 is for being spirally wound on the clad blank strip on body 1 outer wall.
The plastic helical bellow production technology of said structure is: body 1 is formed by body blank strip spiral winding, body plastics blank strip spiral winding becomes in the process of body 1 by corrugated pipe production equipment, simultaneously spiral winding plastic tube thus form spiral helicine stiffening rib 2 on shaping outer surface of tube body, while wound plastic tube, clad plastics blank strip is also wrapped in and body 1 makes clad plastics blank strip and body 1 is molten is connected as a single entity, thus form the clad 3 be coated on by stiffening rib 2 on body 1.Above-mentioned production technology is prior art, is well known to those skilled in the art, and no longer enters to repeat to detail at this.
As shown in Figure 2, described body plastics blank strip comprises blank strip body 4, the upper surface of blank strip body 4 is interval with many with the isometric convex tendon 5 of blank strip body, the upper surface of blank strip body 4 is to the upper bonding jumper 6 extending to form thickness outside and be less than blank strip body, the lower surface of blank strip body 4 is to the lower bonding jumper 7 extending to form thickness outside another and be less than blank strip body, and the thickness sum of lower bonding jumper 7 and upper bonding jumper 6 equals the thickness of blank strip body 4.Above-mentioned convex tendon 5 the intensity that can improve body plastics blank strip is set, and then improve the intensity of body, during body plastics blank strip spiral winding, lower bonding jumper 7 and upper bonding jumper 6 form a pair faying surface, the two its thickness that overlaps is identical with the thickness of blank strip body 4, and the uniform wall thickness of body can be made consistent.
As shown in Figure 3, described clad plastics blank strip comprises blank strip main body 8, the upper surface of blank strip main body 8 is interval with many with the isometric rib 9 of blank strip main body, rib 9 arranges the intensity that can improve coating plastics blank strip.
As shown in Figure 4 and Figure 5, the outer wall of described plastic tube is provided with many spaced ring muscle 10, arranging of ring muscle 10 one is the intensity that can improve plastic tube self, and two is to improve plastic tube and body and clad area of contact, and what plastic tube was connected with body and clad is more firm.
