VACUUM SUCTION CUP Russian patent published in 2023 - IPC A47G29/87 

FIELD: suction device.

SUBSTANCE: vacuum suction cup contains a suction plate formed in the form of a disk of a given thickness and equipped with a disk-shaped insert with a connecting protrusion in the centre, and the said insert is configured to provide selective suction through its lower surface; a rotor having a cylindrical shape and provided with a connecting hole passing through its centre and guide projections extending from the opposite sides of the outer circumference of the rotor, the said rotor being centred on an upper surface of the suction plate by using the connecting hole and the connecting projection of the insert; a base including: a disc-shaped connecting part for a suction plate configured to accommodate the suction plate at its lower part; and a rotor connecting part protruding in the form of a cylinder at the centre of the upper surface of the connecting part for the suction plate, allowing the rotor to be placed therein and moved up and down, the rotor connecting part being provided with a pair of penetrating guide grooves for the rotor and a pair of penetrating connecting grooves for the cap at a given point on its outer circumferential surface; and a cap having the shape of a wide cylinder with an open lower part and equipped with a central through hole, said cap being rotatably mounted on the upper part of the base by means of a pair of hooks clamped in a pair of connecting grooves for the cap by a connecting part of the base under the rotor passing through the through hole to apply external force to the rotor.

EFFECT: configuration that allows for multiple suction, has a super-strong structure and can be attached and detached, while simultaneously exhibiting high adhesion ability to the surface during operation.
