Abstract
A liftable hinge mechanism includes a base, a connecting component and a pin. The base has a narrow slot. The connecting component has an axle hole. The pin slidably passes through the narrow slot and rotatably inserts into the axle hole. The connecting component can be rotated and/or shifted relative to the base via the pin. A reciprocating engaging mechanism includes a shaft, a rotary plate, a first engaging component and a linkage module. The rotary plate is rotatably disposed on the shaft. The linkage module is connected between the rotary plate and the first engaging component. Rotation of the rotary plate drives the linkage module to move the first engaging component into a locking mode or an unlocking mode. The liftable hinge mechanism and the reciprocating engaging mechanism are applied to an airtight device with a housing and a cover capable of being folded and unfolded.
