Described proposes cover structure design rationally, various pieces close fit, in assembly first by hold-down support card Dress is fixed on pallet, the pallet by guide post and hold-down support on chuck guiding mounting hole and guide and limit hole match Close, realize the connection between pallet and chuck, the end of the guide post and hold-down support stretches out respectively guiding mounting hole with Guide and limit hole is equipped with pivoted frame between the extension end of the guide post, and the extension end of hold-down support is equipped with limited block, described Voussoir on limited block and pivoted frame cooperates, and then withholds on mounting hole again by gland, the rotary movement of pivoted frame is by above it Gland driving is pressed, the bottom end for mentioning pot cover pedestal later is equipped with pressure ring engaged therewith, finally installs sealing cover, sealing cover Upper end and the bottom end of pallet screw connection, clamp sealing ring in the card slot of sealing cover, when specific movement: closure: by by pressing Gland drives pivoted frame rotation by gland, to drive tray motion, tray motion drives sealing cover movement, and sealing cover movement makes Butterfly sealing ring and pressure ring cooperate, to realize that butterfly sealing ring cooperates with the sealing for mentioning pot inner cavity；It opens: by pressing again Gland is pressed, is led by the triangle limit that gland drives pivoted frame rotation that the U-shaped fixed link for pressing base end face is made to be detached from hold-down support It to block, is bounced by gland, while under the action of spring restoring force, pallet downward actuation, drives sealing cover downward, butterfly sealing Circle is detached from the compression spreading of pressure ring, thus make butterfly sealing ring and mention it is endless hermetically sealed between pot inner cavity, so that singlehanded lifting is It is openable.

To sum up structure of the invention design rationally, can not only prevent inner box from mentioning generation shaking and abnormal sound in pot, and can rise Open closure function to quick, by pressing it is intermediate press gland, make elastic guide position-limit mechanism that sealing cover be driven to move up and down, One-handed performance, it is time saving and energy saving, meet convenient and practical requirement, it is easy to operate in whole process, it is time saving and energy saving, And good airproof performance, meet requirement.
