Liftable cover

Abstract

A structure of a liftable cover includes a cover having a pivoting end and a covering seat that allows the cover to be disposed thereon. The covering seat is formed thereon with a notch. Both sides of the notch are formed with a sidewall for the covering seat respectively. The notch is hollowed in the vertical direction. Both ends of the pivoting end of the cover are pivotally provided with a pivotal sliding block. The sidewalls on both sides of the covering seat are provided with a sliding trough to correspond to the pivotal sliding block respectively. The two pivotal sliding blocks slide into the two sliding troughs and are connected thereto respectively. Via the indirect pivotal connection of the two pivotal sliding blocks, components can be replaced and assembled in a rapid and convenient manner.
