Document Type and Number:
WIPO Patent Application WO/2018/068412
Kind Code:
A1
Abstract:
A suction cup with a press ring comprises a suction pad (3), a rounded suction switch cap (1), and a tightening press ring (2). The tightening press ring is provided in an axial direction between the suction pad and the rounded suction switch cap. A portion of the suction pad passing through the tightening press ring is in thread engagement with the rounded suction switch cap, such that the tightening press ring is tightly pressed against and connected to the aforementioned two components. In the suction cup with a press ring, turning the rounded suction switch cap enables an edge of the suction pad to tightly press against a medium while pulling a middle portion of the suction pad in a direction away from the medium, such that contact of the suction pad with the medium and vacuum performance of the suction pad are ensured, thereby enabling the suction cup with a press ring to be installed securely. The suction cup with a press ring of the invention can be used conveniently, and has improved safety and convenience.
