Publication number: 20200288903Abstract: A sealing gasket with two deformation spaces is configured to be mounted in a cup-shaped structure and has a through bore that opens on the top and bottom sides of the sealing gasket. The sealing gasket is characterized in that: an inner deformation space and an outer deformation space extend downward into the top side of the sealing gasket, the inner deformation space is adjacent to the through bore such that an inner deformable portion is formed between the inner deformation space and the through bore, and the outer deformation space is adjacent to the outer wall of the sealing gasket such that the outer wall forms an outer deformable portion corresponding to the outer deformation space. The two deformation spaces provide the sealing gasket with enhanced deformability to adapt to a through hole whose diameter may vary within engineering tolerances.Type: ApplicationFiled: June 13, 2019Publication date: September 17, 2020Inventor: Ming-Tung LIU

Patent number: 8479644Abstract: An assembly structure of a rigid body and an elastic body is provided. The rigid body made of glass or ceramics has a chamber and an opening exposing the chamber. The elastic body made of plastics has an indentation and a through hole inside the indentation. The assembly structure further contains an interface element attached to a bottom side of the chamber and has an extension element corresponding to the opening of the chamber. The interconnection between the rigid and elastic bodies is achieved by joining the extension element with the indentation so that the rigid and elastic bodies could be easily put together and separated. The advantages of the rigid body such as robust to deformation and fine surface finish are thereby combined with the advantages of the elastic body such as easy shaping and assembly.Type: GrantFiled: January 28, 2010Date of Patent: July 9, 2013Inventor: Ming-Tung Liu
