ABSTRACT:
It is an automatically lifting devise for toilet seat; the device mainly comprises a sleeve shaft, a sleeve, a main shaft, a torsional spring, and a torsion adjusting assembly. The aforesaid torsion adjusting assembly further includes a displacement shaft, a shaft seat, a worm gear and a worm. The feature of the aforesaid lifting device is that when the lid being lifted up, the toilet seat will be lifted upwards automatically and slowly because of the torsion of the torsional spring is higher than the gravity of the toilet seat, and because of a grease of high viscosity being coated on the surface between the sleeve shaft and the sleeve; moreover, the object of the torsion adjusting assembly is to adjust the torsion of the torsional spring after a long period of use so as to maintain the automatically lifting device to have a normal torsional spring and operation.
