Abstract:
Disclosed are an O-ring vacuum sealing structure, and a vacuum apparatus comprising the O-ring vacuum sealing structure. The O-ring vacuum sealing structure comprises a mounting member (20) and a sealing ring (26), the mounting member being provided with a sealing groove (22) in which the sealing ring is arranged; and same further comprises an accommodating groove (28) and a positioning exhaust block (30), the accommodating groove being provided in the mounting member and being in communication with the sealing groove, and the positioning exhaust block being detachably arranged in the accommodating groove and abutting against the sealing ring. In the O-ring vacuum sealing structure, the mounting member is provided with the accommodating groove for embedding the positioning exhaust block, which ensures the integrity of the sealing groove and allows the sealing groove to limit the side wall of the sealing ring so as to reach the predetermined amount of compression deformation when the sealing ring is pressed, thereby achieving better sealing. In addition, when the sealing ring is removed, there is no need to use a special pry hook tool, which prevents scratching of a sealing face of the mounting member or the sealing ring by the pry hook tool so as to ensure the sealing effect during the re-assembly and use of same.
