Abstract
The utility model discloses a single wall PP (Polypropylene) bellows which comprises a pipe body made of PP plastic, and is characterized in that the pipe body is in an axisymmetrical pipy structure, wherein annular grooves and annular bosses are arranged on a side wall of the pipe body at intervals mutually; the cross section of a bus of the PP bellows is in a waviness shape formed by an interconnected I-shaped structure; and wave troughs of the annular grooves and wave crests of the annular bosses in the waviness shape are horizontal planes respectively. The single wall PP bellows is reasonable in structural design; the structural strength of a product is ensured; threading in the pipe is unaffected; and the operating requirement is met.
Description
Technical field
The utility model relates to a kind of bellows, relates in particular to a kind of single wall PP bellows.
Background technique
Other material bellowss such as plastics have irreplaceable effect in fields such as medium transport, electric power threading, lathe, household electrical appliances, and singel-ply bellows is used more.Multiply bellows intensity is high, good endurance, and stress is little, is used in the important measurement.And existing singel-ply bellows is simple in structure, but its bearing strength is limited, can affect threading in pipe simultaneously, can not satisfy usage requirement.
The model utility content
The purpose of this utility model is in order to remedy the deficiency of prior art, a kind of single wall PP bellows to be provided, solved existing singel-ply bellows simple in structure, but its bearing strength is limited, can affect threading in pipe simultaneously, can not satisfying the problems such as usage requirement.
The utility model is achieved through the following technical solutions:
A kind of single wall PP bellows, include the body that the PP plastics are made, it is characterized in that: described body is with axisymmetric tubular structure, the sidewall of described body is provided with annular groove and the annular boss of space, the cross section of its bus is the bellows-shaped that interconnective I-shape construction forms, and the crest of the trough of annular groove and annular boss is respectively horizontal plane in the described bellows-shaped.
All adopt between the junction surface of the trough of described annular groove and the crest of annular boss and seamlessly transit.
The pipe thickness at described trough place is greater than the pipe thickness at crest place.
Its principle is: because of the intensity of PP material own high, so products material is selected the PP material, product cross section is the bellows-shaped that interconnective I-shape construction forms, be engaged in trough and trough place and do the flat construction processing, the intensity of the product structure that namely guarantees, do not affect again threading in pipe, satisfied usage requirement.
The utility model has the advantages that:
The utility model reasonable in design, the intensity of the product structure that namely guarantees does not affect again threading in pipe, has satisfied usage requirement.
Description of drawings
Fig. 1 is the utility model structure sectional view.
Embodiment
Referring to accompanying drawing, a kind of single wall PP bellows, include the body 1 that the PP plastics are made, body 1 is with axisymmetric tubular structure, the sidewall of body 1 is provided with annular groove 2 and the annular boss 3 of space, the cross section of its bus is the bellows-shaped that interconnective I-shape construction forms, and the crest 5 of the trough 4 of annular groove 2 and annular boss 3 is respectively horizontal plane in the bellows-shaped; All adopt between the junction surface of the trough 4 of annular groove 2 and the crest 5 of annular boss 3 and seamlessly transit; The pipe thickness at described trough 4 places is greater than the pipe thickness at crest 5 places.
Claims (3)
1. single wall PP bellows, include the body that the PP plastics are made, it is characterized in that: described body is with axisymmetric tubular structure, the sidewall of described body is provided with annular groove and the annular boss of space, the cross section of its bus is the bellows-shaped that interconnective I-shape construction forms, and the crest of the trough of annular groove and annular boss is respectively horizontal plane in the described bellows-shaped.
