Description of the drawings
Fig. 1 is a kind of structural schematic diagram of air extracting seal lid specific implementation mode of the present invention.
Fig. 2 is enlarged drawing at F1 in Fig. 1.
Fig. 3 is enlarged drawing at F2 in Fig. 1
Specific implementation mode
The invention will be further described with reference to the accompanying drawings and examples：
Referring to Fig. 1-Fig. 3, a kind of air extracting seal lid, including lid 100,100 inside of lid is inner cylinder 110, institute
It is provided with the screw thread that can be assembled with 520 helixseal of bottle on the inner cylinder side wall stated, is provided on 110 top surface of lid
One groove body 101, open pore 102, the second groove body 104 form resigning platform between the open pore 102 and the first groove body 101
103；
102 top inner wall of open pore is fixed with 230 end face seal of diaphragm seal, and the diaphragm seal 230 is equipped with
Several aspirating holes 231, at least one clamping column 410, the clamping column 410 are fitted into sealing hole 221, the sealing hole
221 are arranged on switchboard 220, and described 220 one end of switchboard is connected and fixed with the first groove body, and pressing is provided on the other end
Piece 222 is provided with pulling buckle 210 on the pressing piece 222, and 222 bottom surface of pressing piece is adjacent to resigning platform.
The diaphragm seal is made of highly elastic material, and such as modified silica-gel, the switchboard 220 is using with certain
The material of elasticity is made, such as elastoplastic.
When original state, clamping post part is packed into sealing hole or is not loaded into sealing hole, and diaphragm seal is detached with switchboard.
It is assembled in use, lid 100 is mounted on bottle 520 and is sealed with bottle 520 first, then by suction tube
510 nozzles cover on the first groove body 101, are aspirated to the air in inner cylinder by suction tube, in the process, diaphragm seal meeting
It is adjacent to switchboard 220 under the action of suction (draught head), while clamping column 410 can be across sealing hole 221 and and sealing hole
221 sealings, clamping assembly, to realize to the low pressure or vacuum inside bottle 520, and since diaphragm seal is adjacent in switchboard
On 220, switchboard also have elasticity, therefore external pressure lid can be pressed on bottle, by switchboard with sealing film compacting, from
And realize sealing and preferable sealing effect for a long time.
When needing depressurization, it is only necessary to it pulls with hand pulling buckle 210 and upwards lifts switchboard, in the process,
Clamping column is detached from sealing hole, and outer gas stream enters in inner cylinder, and diaphragm seal is detached from switchboard under the action of its own elastic force.
Further, its end face and lid, which generate gap, when suction tube 510 aspirates in order to prevent influences suction effect, can be with
Bayonet slot ring 1041 is set on the second groove body 104, sealing ring 310 is installed in the bayonet slot ring 1041.In use, suction tube
510 are fitted into the second groove body so that sealing ring 310 is adjacent to sealing with suction inside pipe wall.
Further, 310 inside of sealing ring is hollow cavity 311, sealing ring and 510 contact surface of suction tube
For outwardly projecting cambered surface 311.In use, the cambered surface 311 may be implemented preferably to seal suction tube.And due to close
Seal ring 310 is simultaneously non-solid, can have preferable drawing effect, therefore can relatively easily be fitted into bayonet slot ring 1041.And
When suction tube is aspirated since the air pressure outside cambered surface 311 becomes smaller, cambered surface 311 can expand, to improve sealing effect.
Further, the clamping column top is provided with big end 411 made of highly elastic material, the big end 411
Diameter can make clamping column pass through big end and realize that preferable sealing and clamping are imitated with sealing hole in this way slightly larger than sealing bore dia
Fruit.
Place is not described in detail by the present invention, is the known technology of those skilled in the art.
The preferred embodiment of the present invention has been described in detail above.It should be appreciated that those skilled in the art without
It needs creative work according to the present invention can conceive and makes many modifications and variations.Therefore, all technologies in the art
Personnel are available by logical analysis, reasoning, or a limited experiment on the basis of existing technology under this invention's idea
Technical solution, all should be in the protection domain being defined in the patent claims.
