Floating pivot mechanism, reciprocating clamping mechanism and related airtight device

Abstract

The invention provides a floating type pivot mechanism, a reciprocating clamping mechanism and a related airtight device. The floating type pivot mechanism comprises a base, a connecting piece and a bolt. The base is provided with a long-strip-shaped slot. The connecting piece is provided with a shaft hole. The plug pin penetrates through the long-strip-shaped slot in a sliding mode and rotatably passes through the shaft hole. The connecting piece rotates and / or moves relative to the base through the plug pin. A reciprocating clamping mechanism comprises a pivot, a rotating disc, a first clamping piece and a connecting rod module. The rotating disc is rotatably arranged on the pivot. The connecting rod module is connected between the rotating disc and the first clamping piece. And the connecting rod module drives the first clamping piece to switch and move between a locking mode and an unlocking mode along with the rotation of the turntable. The floating pivot mechanism and the reciprocating clamping mechanism can be applied to an airtight device with a shell and a cover plate which can be opened and closed relatively. The airtight effect of the airtight device can be improved.

Description

technical field [0001] The invention provides a floating pivot mechanism, a reciprocating engagement mechanism and related airtight devices for reducing gas dissipation, especially a floating pivot mechanism and a reciprocating engagement mechanism that can provide better airtight effects and its associated airtight devices to reduce gas escape. Background technique [0002] Traditional airtight equipment places objects to be cooled in the storage space of the tank, and then installs the upper cover on the tank to cover the storage space, and uses the water cooling device in the airtight equipment to cool down; however, the cooling of the water cooling device The liquid will be vaporized due to heating, so the upper cover of the airtight device needs to provide a stable pressure and bond to the tank to prevent the gas from escaping. The upper cover has opposite first and second sides. The first side is close to the pivot mechanism, and the upper cover is rotatably arranged...

AI Technical Summary

Problems solved by technology

Therefore, the force on the ring gasket is uneven, resulting in inconsistent compression

In the process of closing the upper cover of traditional airtight equipment, there may be defects such as the ring gasket falling out of the installation groove of the tank body, or the upper cover being bent and deformed by force, which will affect the airtight effect of the airtight equipment
