Abstract

The invention discloses an abrasion-proof rotation structure. The abrasion-proof rotation structure is provided with a tightening cap, wherein the tightening cap is provided with a thread suitable to be screwed into a screwed hole; an outer elastic gasket is arranged between the tightening cap and an inner elastic gasket; a contact surface between the outer elastic gasket and the inner elastic gasket is in force fit; the contact surface is gradually expanded along the direction of the tightening cap which is screwed into the screwed hole. When the abrasion-proof rotation structure is practically used and when a clearance between the inner elastic gasket and the outer elastic gasket or between the inner elastic gasket and a rotating shaft exists due to abrasion, the tightening cap is screwed up clockwise or anticlockwise along the direction of the thread on the outer wall of the tightening cap; the tightening cap is extruded to the direction of the front section of the rotating shaft along the thread; meanwhile, the outer elastic gasket downwards moves to extrude the inner elastic gasket so as to solve the problem that a fixing device in the prior art can not be normally used after abrasion.

Description

technical field [0001] The invention relates to a rotating mechanism, in particular to a wear-resistant rotating structure. Background technique [0002] Rotating structures are widely used in faucets and other equipment. The early rotating structure usually uses the clearance fit between the rigid rotating shaft and the hole to realize the rotation. Due to its high strength, this structure is usually used in occasions with high requirements on the life of the parts. However, the defect of this early rotating structure is that: because there is a gap between the shaft and the hole, the rotating shaft is easily deviated from the axial direction of the hole, that is, the phenomenon of "eccentricity" occurs. [0003] In order to solve the problem that the above-mentioned rotating shaft is easy to "eccentric", Chinese patent document CN200946620Y discloses a rotating structure, which provides a device for fixing and adjusting the rotating shaft. The rotating shaft in this paten...
