Description
Technical field
The present invention relates to tubing technical field, specifically relate to a kind of plastic pipe and revolve extrusion sealing part.
Background technology
The feedwater of current building field, draining, exhaust tubing, ratio shared by plastic pipe is more and more higher, be commonly both ends open formula or use packaging bag sealed type, packaging used is all generally that disposable plastic bag is packed, easily break, and the most blowing-by of the port at tubing two ends, cause tubing before non-construction usage, be just easily subject to the pollution of external environment, the pipe fitting that particularly feeds water just was polluted before also not using, can not be guaranteed to the quality of human lives's water after being polluted, the healthy of people brings very large harm.
Existing Chinese patent notification number is steel-belt-pipe otch enclosuring structure disclosed in CN202392311U, comprise polyethylene helical bellows and steel band, steel band is converted into inverted U, by sealing, the cutting part of the steel band of inverted U is closed, and with hot-air heater or electric soldering iron heating and melting, make it to combine together with polyethylene helical bellows, can not there is corrosion in this tubing in storage, transportation.This enclosuring structure can ensure that pipe fitting is not contaminated before not using to a certain extent, but this complex structure, leak tightness and stability deficiency, and can not split, use inconvenience, be also not easy to the packed and transported of plastic pipe.
Summary of the invention
Technical matters to be solved by this invention be to provide a kind of easy to operate, leak tightness is high, stability is strong, collection for convenience detach revolves extrusion sealing part with the plastic pipe installed and used.
For solving the problems of the technologies described above, the invention provides following technical scheme: a kind of plastic pipe revolves extrusion sealing part, comprise elasticity cock body, elasticity cock body comprise corresponding with tubing madial wall in piston part and the outward flange section corresponding with tube end face, interior piston part and outward flange section one-body molded; Described outward flange section is embedded with an annular groove matched with tubing thickness, and slot opening is towards side, interior piston part, and groove cross section is isosceles trapezoid shape left large and right small; Described interior piston part is placed in tubing inside, the tapped bore be connected is coaxially arranged with in interior piston part and outward flange section, the externally threaded screw rod having a band corresponding with tapped bore is rushed across tapped bore and is placed in outside outward flange section inside interior piston part, described screw rod cross-sectional plane is isosceles trapezoid shape left large and right small, one end that screw rod is placed in inside interior piston part is extended with epitaxy part, and epitaxy part external diameter is less than interior piston part external diameter.
On such scheme basis preferably, described screw rod one end be placed in outside outward flange section is connected with a balanced handle.
On such scheme basis preferably, described balanced handle is arranged porose.
The beneficial effect that the present invention compared with prior art has is: wherein, the external flange part of resilient plug is embedded with groove, groove cross section is isosceles trapezoid shape left large and right small, on the left of groove, openings of sizes is corresponding with tubing thickness, in installation process, tube end face is placed in groove, and elasticity cock body more gos deep in tubing, tube end face and groove fit tightr, contribute to improving tubing and elasticity cock body leak tightness and fitment stability; Wherein, in elasticity cock body, expanded by being produced by screw extruding to inner rotary of screw rod in piston part, and then piston part and tubing madial wall leak tightness and fitment stability in improving, and it is easy to install, meanwhile, when not needing to use elasticity cock body, screw rod is inwardly rotated, original state just can be replied in interior piston part, lower collection for convenience detach.
Accompanying drawing explanation
Fig. 1 is that elasticity cock body of the present invention and tubing are with the use of status architecture cutaway view.
Number in the figure is: 1-elasticity cock body, piston part in 11-, 111-tapped bore, 12-outward flange section, 121-groove, 2-screw rod, 21-epitaxy part, 3-balanced handle, 31-hole.
Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
In describing the invention, it will be appreciated that, term " longitudinal direction ", " laterally;;, " on ", the orientation that indicates of D score, "front", "rear", "left", "right", " vertically ", " level ", " top ", " end ", " interior ", " outward " etc. or position relationship be based on orientation shown in the drawings or position relationship; be only the present invention for convenience of description; instead of indicate or imply the device of indication or element must have specific orientation, with specific azimuth configuration and operation, therefore can not be interpreted as limitation of the present invention.
Known with reference to Fig. 1, a kind of plastic pipe revolves extrusion sealing part, comprises elasticity cock body 1, elasticity cock body 1 comprise corresponding with tubing madial wall in piston part 11 and the outward flange section 12 corresponding with tube end face, interior piston part 1 is one-body molded with outward flange section 12; Described outward flange section 12 is embedded with an annular groove 121 matched with tubing thickness, and groove 121 opening is towards side, interior piston part 11, and groove 121 cross-sectional plane is isosceles trapezoid shape left large and right small; Described interior piston part 11 is placed in tubing inside, the tapped bore 111 be connected is coaxially arranged with in interior piston part 11 and outward flange section 12, the externally threaded screw rod 2 having a band corresponding with tapped bore 111 is rushed across tapped bore 111 and is placed in outside outward flange section 12 inside interior piston part 11, described screw rod 2 cross-sectional plane is isosceles trapezoid shape left large and right small, one end that screw rod 2 is placed in inside interior piston part 11 is extended with epitaxy part 21, and epitaxy part 21 external diameter is less than interior piston part 11 external diameter.
