PAD FOR VACUUM SUCTION DEVICE

摘要

PURPOSE: A pad for a vacuum suction device is provided to effectively improve the convenience and stiffness of assembly with a coupling unit because the pad has an inner wall structure and the round and each inner diameter thereof are adroitly designed. CONSTITUTION: A pad(20) for a vacuum suction device(100) comprises a coupling part(22) and a suction part(21). The coupling part supports a coupling unit in a state of closely surrounding the outer surface of the coupling unit upwardly inserted. The suction part is downwardly extended from the coupling part to be contacted on the surface of an object. The coupling part has a support(27) and a sealing protrusion(25). The support is inwardly extended at the bottom of the coupling part and is contacted to the underside of the coupling unit. The sealing protrusion is upwardly extended from the support.
