Abstract
The utility model relates to a kind of collar tension spring type and to stretch blowing pipe, belongs to technical field of hoses.The body of this flexible blowing pipe is circular perpendicular to the cross section of length direction, and the cross section being parallel to length direction is the trough of fluctuating continuously and the wavy of crest formation, when described flexible blowing pipe is in and pulls extended configuration, described trough is in the shape of the letter V, and described crest is formed by transition arc; When described flexible blowing pipe is in and draws nature in, the two side of described trough closes up contact, and described crest becomes semi-circle.Collar tension spring type of the present utility model stretch blowing Guan Wu liner elastic metallic yarn when, relying on the elasticity of plastics self, can realizing stretching by pulling completely, recover rounding state completely after external force release.Its manufacturing process is practical, as long as pulverizing treatment during recovery, very convenient.
Description
Technical field
The utility model relates to a kind of flexible blowing pipe, and especially a kind of collar tension spring type stretches blowing pipe, belongs to fluid delivery pipeline technical field.
Background technique
According to the applicant understood, existing nature be in the stretched flexible pipe of deflated state all need at the corresponding elastic metallic yarn of plastic outer tube liner.This existing flexible pipe not only manufacturing process is comparatively complicated, and when scrapping recycled plastic, the wire of liner is separated to get up extremely to bother.
Model utility content
The purpose of this utility model is: for above-mentioned prior art Problems existing, proposes a kind of collar tension spring type without the need to liner elastic metallic yarn and to stretch blowing pipe, thus slow down Structure and energy, and very convenient when making plastics recycling.
In order to reach above object, the stretch body of blowing pipe of the utility model collar tension spring type is circular, oval or other shape perpendicular to the cross section of length direction, and the cross section being parallel to length direction is the trough of fluctuating continuously and the wavy of crest formation, when described flexible blowing pipe is in and pulls extended configuration, described trough is in the shape of the letter V, and described crest is formed by transition arc; When described flexible blowing pipe is in and draws nature in, the two side of described trough closes up contact, and described crest becomes semi-circle.
During manufacture, first pull by inner chamber and flexible blowing pipe the mould blow molding that extended configuration matches, after being pressed setting to toast afterwards on shaping mould, namely can be made into the stretched flexible pipe that nature is in deflation.Collar tension spring type of the present utility model stretches after blowing pipe can realize being subject to pull stretching, extension, external force release and recovers rounding state completely.Obviously, its manufacturing process is practical, as long as pulverizing treatment during recovery, very convenient.
Further, when described flexible blowing pipe is in and pulls extended configuration, trough is the V-shaped that base angle is 90 °.
Further, the angular bisector at described base angle departs from the vertical line in tube length direction, forms the angle of slip of 2 °-8 °.
Further again, when described flexible blowing pipe is in and pulls extended configuration, the pitch of waves that fluctuating trough and crest are formed and wave height are than being 1.5-2.5.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.
Fig. 1 is the gathering nature structural representation of the utility model embodiment.
Fig. 2 is the perspective view of Fig. 1.
Fig. 3 is the pulling extended configuration structural representation of Fig. 1 embodiment.
Fig. 4 is the A place partial enlarged drawing of Fig. 3.
Embodiment
Embodiment one
The collar tension spring type of the present embodiment stretches blowing pipe as shown in Figure 1, Figure 2, Figure 3 shows, body 1 is circular, oval or other shape perpendicular to the cross section of length direction, and the cross section being parallel to length direction is the trough 1-1 of fluctuating continuously and the wavy of crest 1-2 formation.During manufacture, first pull by inner chamber and flexible blowing pipe the mould blow molding that extended configuration matches, as shown in Figure 3 and Figure 4, trough 1-1 is the V-shaped that base angle is 90 °, and the angular bisector a at base angle departs from the vertical line b of body 1 length direction, form the angle of slip of 5 ° (2 °-8 ° also can), like this can in flexible blowing pipe telescopic process, when especially drawing at it, produce self contering leading role, thus make flexible blowing pipe have the trend keeping axial stretching.Crest 1-2 is formed by transition arc, and this circular arc can be determined by pitch of waves T and wave height H ratio, and pitch of waves T and the wave height H ratio of the present embodiment are about 2 (1.5-2.5 also can).Pressed afterwards on shaping mould, flexible blowing pipe is in and draws nature setting in, as depicted in figs. 1 and 2, the two side of trough 1-1 closes up contact, and crest 1-2 becomes semi-circle.The stretch two ends of blowing pipe of collar tension spring type form interface 1-3,1-4 of disjunctor respectively.
Test proves, collar tension spring type of the present utility model stretch blowing Guan Wu liner elastic metallic yarn when, relying on the elasticity of plastics self, can realizing stretching by pulling completely, recover rounding state completely after external force release.Its manufacturing process is practical, during recovery, as long as pulverizing treatment.
In addition to the implementation, the utility model can also have other mode of executions.All employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
