The invention discloses a simple wall curtain in the field of projection curtains. The simple wall curtain includes a curtain. A plurality of curtain through holes are arranged in the peripheral edgesof the curtain. The curtain is unfolded and spread out to be fixed on a frame. The frame includes an outer frame and an inner frame, and the inner frame and the outer frame are fixedly connected to each other through a plurality of connecting rods. The inner frame is provided with a plurality of tension adjusting mechanisms that correspond to the curtain through holes and that is capable of tensioning the curtain. A mounting boss is arranged on the inner frame, and the tension adjusting mechanisms are arranged on the mounting boss. The curtain is unfolded and spread on front sides of the outer frame and the inner frame, the peripheral edges of the curtain are turned over backwards to cover the peripheral sides of the outer frame, and then the curtain is fixedly connected with the tensionadjusting mechanisms on the inner frame to make the curtain arranged on the frame in a tensioned manner. The inner frame is further provided with a plurality of suspension fixing assemblies that enable the frame to be hung stably. The advantages are that the simple wall curtain has a simple structure, can be stably hung, can be conveniently fixed, and exhibits good use effects.
Description
technical field [0001] The invention relates to the field of projection screens, in particular to a simple wall screen. Background technique [0002] The projection screen is the carrier used by the projector to project images and video files, and is usually used in offices, home theaters, large conferences and other occasions.
