Suction cup structure
A suction cup structure includes a housing including a connector and a bracket. A tube is connected to the connector. The bracket includes an accommodation recess. A magnet is located within the accommodation recess and a gasket is at a center of the magnet. A suction cup assembly includes a screw component and a suction cup. The screw component includes a head portion which is securely connected to a protrusion on a top of the suction cup. The head portion includes passages in which material of the protrusion of the suction cup is filled during production. The threaded shaft of the screw component extends through the gasket and is threadedly connected to a screw hole located within the accommodation recess of the housing.
1. A suction cup structure comprising:
a housing ( 1 ) including a connector ( 11 ) and a bracket ( 13 ), the connector ( 11 ) including an end hole ( 12 ), one of two ends of a tube ( 100 ) connected to the end hole ( 12 ) of the housing ( 1 ), the bracket ( 13 ) including an accommodation recess ( 14 );
a magnet ( 2 ) located within the accommodation recess ( 14 ) and having a central perforation ( 21 ), a gasket ( 3 ) located in the central perforation ( 21 ), and
a suction cup assembly ( 4 ) comprising a screw component ( 41 ) and a suction cup ( 42 ), the screw component ( 41 ) including a threaded shaft ( 411 ) and a head portion ( 412 ), the head portion ( 412 ) connected to a protrusion ( 421 ) on a top of the suction cup ( 42 ), the suction cup ( 42 ) having a suction recess ( 422 ) formed in an underside thereof, the head portion ( 412 ) including multiple passages ( 413 ), the protrusion ( 421 ) of the suction cup ( 42 ) being formed in the passages ( 413 ) that provides multiple ribs ( 423 ) in the passages ( 413 ), the threaded shaft ( 411 ) of the screw component ( 41 ) extending through the gasket ( 3 ) and threadedly connected to a screw hole ( 141 ) located within the accommodation recess ( 14 ) of the housing ( 1 ).
2. The suction cup structure as claimed in claim 1 , wherein a positioning member ( 5 ) is installed within the accommodation recess ( 14 ) of the housing ( 1 ), the positioning member ( 5 ) is a disk-shaped member and includes a peripheral wall extending from a periphery thereof so as to form a recessed area ( 51 ) in an underside of the positioning member ( 5 ), an outer peripheral surface of the peripheral wall of the positioning member ( 5 ) abuts against an inner periphery of the accommodation recess ( 14 ).
3. The suction cup structure as claimed in claim 1 , wherein a central part ( 142 ) is formed to a center of the accommodation recess ( 14 ) of the housing ( 1 ), multiple flanges ( 143 ) are formed between an outer periphery of the central part ( 142 ) and an inner periphery of the accommodation recess ( 14 ).
4. The suction cup structure as claimed in claim 3 , wherein the central part ( 142 ) includes a threaded sleeve ( 144 ) located centrally in a distal end thereof, the screw hole ( 141 ) is formed in the threaded sleeve ( 144 ), the screw component ( 41 ) is threadedly connected to the screw hole ( 141 ) of the threaded sleeve ( 144 ).
5. The suction cup structure as claimed in claim 1 , wherein the suction cup ( 42 ) is deformed to create a vacuum state between the suction cup ( 42 ) and an object.
6. The suction cup structure as claimed in claim 1 , wherein a threaded hole ( 121 ) is formed in the end hole ( 12 ) of the connector ( 11 ), the tube ( 100 ) has a threaded rod ( 200 ) which is threadedly connected to the threaded hole ( 121 ).
7. The suction cup structure as claimed in claim 1 , wherein the magnet ( 2 ) includes a recessed area ( 22 ) located corresponding to the suction cup ( 42 ), when the suction cup ( 42 ) is deformed, the suction cup ( 42 ) is accommodated within the recessed area ( 22 ).
