Abstract

A toilet seat structure including a toilet seat, a link, a pedal and a fixing plate can be lifted up through the pedal. The toilet seat is connected to one end of the link. The other end of the link is pivoted on the pedal. A middle of a bottom surface of the pedal is mounted with the fixing plate. Stamping the pedal can raise the other end to move the link and push the toilet seat to rotate upward according to the connection structure. When the pedal is loosened, the toilet seat automatically restores to be horizontally placed on a toilet bowl to make the link and the pedal restore. Thus, the cleanliness and sanitation of the toilet seat can be kept, and the position of the toilet seat can be conveniently changed by the stamping foot.
