Abstract

The embodiment of the invention provides a curtain lifting mechanism and projection equipment. The curtain lifting mechanism comprises a base, a winding device, a curtain and a folding device; the winding device is mounted on base, the curtain is provided with a first edge and a second edge opposite to the first edge; the first edge is connected to the winding device, the winding device can wind the curtain through the first edge, the folding device comprises a telescopic support and an elastic component, the telescopic support is connected with the base and the second edge of the curtain, thetelescopic support can contract or extend relative to the base to drive the second edge to be close to or away from the base, and the elastic component is elastically connected to the telescopic support to provide elastic force for unfolding the telescopic support relative to the base so that the curtain can be kept flat after being unfolded. After the winding device unfolds the curtain, the curtain is kept in a flattened state through the telescopic support and the elastic component, the curtain can overcome the influence of gravity, the unfolding mode from bottom to top is achieved, and thebase can be placed on any platform and does not need to be hung on a ceiling.
