Abstract
A reciprocating engaging mechanism is applied to an airtight device and includes a shaft, a rotary plate, a plurality of first engaging components and a linkage module. The rotary plate is rotatably disposed on the shaft. A plurality of bridging bars of the linkage module is connected between the rotary plate and the plurality of first engaging components in a respective manner, rotation of the rotary plate drives the plurality of bridging bars to rotate in the same direction, so as to switch the plurality of first engaging components between a locking mode and an unlocking mode.
Claims4
An airtight device of preventing gaseous matter from leakage, comprising:
- a cover;
- a housing, the cover being movably assembled with the housing, a groove being formed on a side of the housing facing the cover;
- a liftable hinge mechanism connected to the housing and the cover, the liftable hinge mechanism comprising:
- a base disposed on the housing and having a narrow slot;
- a connecting component connected to the cover and having an axle hole;
- and
- a pin slidably passing through the narrow slot and rotatably inserting into the axle hole, multi-dimensionally liftable motion of the connecting component relative to the base being generated via a movement of the pin inside the narrow slot and the axle hole, so as to seal the housing by the cover for preventing the gaseous matter inside the housing from leakage;
- and
- a resilient gasket disposed inside the groove on the housing, wherein the cover is in a level state when contacting the resilient gasket due to liftable motion of the liftable hinge mechanism;
- wherein the liftable hinge mechanism further comprises a constraining component disposed between the base and the connecting component, two opposite surfaces of the constraining component respectively abut against the base and the connecting component in a slidable manner.
