Description
Technical field
The present invention relates to planar linkage mechanism fields, and in particular to a kind of open-and-close mechanism of vacuum reservoir cylinder cap.
Background technique
Nano impression field also can apply recessed AB glue, AB glue first in cylinder body after mixing need to also into cross air-extraction function,
The bubble mixed in glue can be extracted, that just needs to be sealed cylinder body.It is to the sealing of vacuum reservoir in the prior art
One circle of cylinder cap is bolted, needs that manually each bolt is locked or removed, inefficiency is also easy to appear
Part locking loosely the case where, so that influence vacuum reservoir vacuumizes operation.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of open-and-close mechanism of vacuum reservoir cylinder cap, realization cylinder cap and vacuum cylinder body
Quickly open and close and improve air-tightness.
To solve the above problems, the present invention provides a kind of open-and-close mechanism of vacuum reservoir cylinder cap, in order to achieve the above objectives, this hair
Technical solution used by bright its technical problem of solution is：
A kind of open-and-close mechanism of vacuum reservoir cylinder cap, including：Cylinder cap, positioned at the top of vacuum cylinder body；Fixed bin is located at cylinder cap
Top and spatial position is fixed；Link mechanism is made of first connecting rod, the second connecting rod being hinged, and first connecting rod is separate
One end of second connecting rod is connect by first rotating shaft with fixed bin, and second connecting rod passes through vertical shape in one end far from first connecting rod
The compression bar of state is connect with cylinder cap, and the own axes of compression bar own axes and first rotating shaft are located in the same space perpendicular；It is dynamic
Power part is connect with the hinged place of first connecting rod, second connecting rod, and force piece exports the reciprocal motional force along straight line, to change the
The mutual corner dimension of one connecting rod, second connecting rod；Fixed bin is equipped with vertical waist-shaped hole, the hinged place of second connecting rod and compression bar with
Waist-shaped hole assembly connection is provided simultaneously with the vertical alternating translational freedom degree along waist-shaped hole length direction.
Beneficial effect by adopting the above technical scheme is：There is provided that a kind of just efficiently means of press seals, upper lift are opened under cylinder cap
Mechanism improves the folding efficiency of vacuum reservoir, directly snaps together cylinder cap using big pressure with vacuum cylinder body, guarantee cylinder cap with
The air-tightness of vacuum cylinder body guarantees the completion that operation is vacuumized in vacuum reservoir.Again due to link mechanism component, force piece
Lesser power can be exported, connecting rod can be downwardly applied to biggish power.The interaction force of last vacuum reservoir and cylinder cap is very big,
Reach dead point when connecting rod is finally in vertical straight angle state, pressing force depends on the structure compression strength of connecting rod material itself.It is perpendicular
To waist-shaped hole can guarantee that the upper end of compression bar moves in a vertical straight line always, prevent compression bar crooked.
As a further improvement of the present invention, force piece is cylinder, and cylinder passes through Telescopic-cylinder arm and first connecting rod, second
The hinged place of connecting rod connects, and cylinder is fixed by the second shaft with fixed bin, and cylinder has the rotational freedom around the second shaft,
Second shaft is parallel with first rotating shaft direction and does not coincide with the same space perpendicular.
