Abstract

The invention provides a projection device for interactive visual communication, and mainly relates to the field of projection devices. The projection device for interactive visual communication comprises: a first fixing seat; slideways, wherein the slideways are arranged in parallel on the horizontal direction; a first rotating shaft, wherein the first rotating shaft is rotatably connected with the first fixing seat; a first motor, wherein a first transmission device is disposed between the first motor and the first rotating shaft; a curtain, wherein the curtain can be wound on an outer wallof the first rotating shaft; a second fixing seat; a second rotating shaft, wherein the second rotating shaft is rotatably connected with the second fixing seat; a hoisting wheel, wherein a ring groove is formed in a side wall of the hoisting wheel; a hoisting belt, wherein the width of the hoisting belt adapts to the width of the ring groove; and a second motor, wherein a second transmission device is arranged between the second motor and the second rotating shaft. The projection device for interactive visual communication provided by the invention has the beneficial effects of being able oflaterally expand the projection screen to enlarge the projection display area, so that rich multimedia information can be effectively displayed.

Description

technical field [0001] The invention mainly relates to the field of projection equipment, in particular to a projection device for interactive visual communication. Background technique [0002] Projection equipment is widely used today, which enriches the way of publicity, makes people receive information more diversely, and the content is more vivid. Visual communication is expressed and communicated to the audience through visual media, which embodies the characteristics of the times and rich connotations of design. The emergence of digital multimedia constantly challenges and enriches traditional visual communication methods, and expands the extension of contemporary visual communication design. The planarization and staticity in form began to gradually change to dynamic and comprehensive direction, from single media to multimedia, from two-dimensional plane to three-dimensional and space, and from traditional printing design products to virtual information convey the i...
