Abstract

L'invention concerne une structure d'amortisseur d'abattant de toilettes, comprenant un manchon de corps de vanne (1), un manchon de carter (2) et un amortisseur (3), où le manchon de corps de vanne (1) et le manchon de carter (2) s'engainent respectivement à l'une et l'autre extrémité de l'amortisseur (3). La dimension radiale du manchon de carter (2) peut être conçue à la demande, selon les exigences, à des tailles différentes, de sorte que les exigences en termes d'abattants de toilettes de différentes tailles peuvent être satisfaites. Une lame (36) de l'amortisseur (3) est collée à une paroi externe d'une nervure (354) du corps de vanne (35), et une pièce de blocage (361) et une pièce de limitation (362) sur la lame (36) sont respectivement agencées de part et d'autre de la nervure (354) du corps de vanne (35). Grâce à la réduction appropriée des tailles des deux nervures (354) de la lame (36) sur le corps de vanne (35), un angle d'ouverture de l'amortisseur est augmenté pour garantir l'intégrité des pièces. La fonction d'amortissement est réalisée au moyen d'un déflecteur d'huile (373) sur un carter de cavité à huile (37) qui coopère avec la nervure (354) sur le corps de vanne (35) et une face de paroi du corps de vanne, et une surface d'une face saillante interne du déflecteur d'huile (373) et une rainure à huile de décompression (355) qui forment un passage d'écoulement d'huile d'amortissement, rendant l'action d'oscillation de l'abattant de toilettes plus stable. Une bague rotative (34) est en outre adjointe en même temps, ce qui permet de garantir la stabilité du temps de descente lent de l'abattant de toilettes.
