Title:
DAMPING ROTATING SHAFT MECHANISM WITH SELF-COMPENSATING SEAL AND TOILET COVER HAVING SAME
Document Type and Number:
WIPO Patent Application WO/2015/161797
Kind Code:
A1
Abstract:
A damping rotating shaft mechanism with self-compensating seal and a toilet cover having the same, comprising a rotating shaft (1), a guide sleeve (2), a housing (3) and a blade (4). The housing is in threaded connection with the guide sleeve; the guide sleeve and the rotating shaft are arranged in the housing and the inner cavity of the housing is partitioned into a first cavity (31) and a second cavity (32) by the guide sleeve. The guide sleeve is provided with a first channel (61) connecting the first cavity with the second cavity. The blade is movably arranged on the guide sleeve and located on the side of the first channel close to the second cavity so as to open/close the first channel. The blade is annular or arc-shaped to match the inner wall surface of the housing. The blade is provided with a first thin wall (41) capable of deforming. The first thin wall deforms toward the inner wall surface of the housing when the blade moves towards the second cavity. Through the arrangement of the self-compensating structure, clearances caused due to mechanical abrasion can be automatically compensated when the fit clearances between those components become large, and therefore the damping rotating shaft mechanism is kept in a stable state for a long time, and the service life of the damping rotating shaft mechanism is prolonged.
