Description
Technical field:
The present invention relates to a kind of container plunger, relate in particular to a kind of tear drop bottle special piston.
Background technology:
Piston be a kind of be used for bearing gas pressure parts, in various containers, be all used to.In existing piston, piston is fixed structure, and people are directly placed in appearance by piston in the process usingIn device, with the effect of playing sealing and bearing gas pressure. But along with the development in epoch, simple and easy merit like thisCan piston cannot meet people's demand at all, existing piston on air isolated, the making of pistonWith all perfect not with the sealing property of taking-up, piston, user is caused to great inconvenience, to producingQuality has caused great threat.
Summary of the invention:
For the deficiencies in the prior art, the present invention has designed a kind of tear drop bottle special piston, by piston only andSeal cover composition, described piston only is cylindrical, is provided with a groove at the top of piston only, recessedThe outward flange of groove is provided with sealing ring A, is provided with cylindrical hole in the centre of groove; One end at groove is provided withOne passage, described passage is through whole piston only; Side at piston only is provided with indenture, instituteThe indenture of stating is embedded with sealing ring B; Bottom surface at piston only is provided with setscrew nut; Described seal cover is by coveringBody and cylinder plugs composition, lid is round pie, its diameter is identical with the diameter of piston only; At lidBe provided with a passage, described passage is through whole lid; Have cylinder plugs at lid, instituteThe cylinder plugs diameter of stating is identical with the diameter of the cylindrical hole of groove centre, in cylinder plugsBottom is provided with a through hole; Above lid, be provided with projection, on projection, be provided with hook hole.
As a further improvement on the present invention: described cylindrical hole is being less than near the size of groove one endAway from groove one end.
As a further improvement on the present invention: described setscrew nut quantity is 2.
As a further improvement on the present invention: in described cylindrical hole, be also provided with spring.
Beneficial effect of the present invention: sealing property is splendid, installation and removal are simple, and can effectively isolate skyGas.
Brief description of the drawings:
Fig. 1 is main TV structure figure of the present invention;
Fig. 2 is the main TV structure figure of piston only of the present invention;
Fig. 3 is the main TV structure figure of seal cover of the present invention;
Wherein, 1-projection, 2-lid, 3-piston only, 4-sealing ring B, 5-setscrew nut, 6-through hole,7-cylinder plugs, 8-groove, 9-sealing ring A, 10-cylindrical hole, 11-passage, 12-hook hole.
Detailed description of the invention:
A kind of tear drop bottle special piston of the present invention, first inserts the cylinder plugs of seal cover 7 piston only 3In cylindrical hole 10, then by a metallic rod through the through hole 6 of cylinder plugs 7 bottoms, metallic rod is fixedBetween two setscrew nuts 5; Owing to being provided with a spring in cylindrical hole 10, when metallic rod is through logical, the elastic force of spring acts in metallic rod when in the hole 6, and metallic rod and through hole 6 are close together, sealingBetween lid and piston only 3, reach the effect of zero leakage. The projection 1 that twists again lid 2 tops, makes lid 2On passage 11 be conducted with the passage 11 on piston only 3, by special a kind of the present invention tear drop bottlePiston is slowly inserted in the container that fills material, and extruding, makes the air in container arrange from passage 11 downwardsGo out; In the time having a little material to overflow from passage 11, again twist projection 1, make upper and lower 2 passages 11Stagger, complete exhaust work.
The present invention, by 2 setscrew nuts 5 are set in bottom, makes the anglec of rotation of lid 2 be fixed on oneIn scope. In the time rotating lid 2 to one end, two passage 11 conductings; When rotation lid 2 is to the other endTime, two passages 11 are isolated completely, very easy to use, and moment is very little.
The present invention all arranges sealing ring in the groove 8 of piston only 3 and in the indenture of piston only 3 sides,Make very perfect of sealing property of the present invention. When the material in container be used up finish time, piston also canAlong with material declines, because the pressure in container is very large, take out piston and become particularly difficulty, the present invention passes throughOne hook hole 12 is set on the projection 1 at lid 2 tops, when material is finished using need to take out piston time,Only hook need be stretched in container, aim at hook hole 12, once piston be taken out, very easy to use.
