Combined truss for holographic projection curtain wall

Abstract

The invention relates to the technical field of holographic projection, and discloses a combined truss for a holographic projection curtain wall. The combined truss comprises a truss body, an installation plate is fixedly installed on the front face of the truss body, a curtain roll is installed on the front face of the installation plate in a sliding mode, a projection screen is stretched out ofone side of the curtain roll, a pull column is fixedly installed at one end of the projection screen, and a transverse frame is fixedly installed in the middle of a truss stand column. According to the combined truss for the holographic projection curtain wall, the curtain roll is vertically arranged at one side of a truss; the projection screen is driven by rotation of wind-blowing fan blades todrive the belt to rotate, so that a pull column pulls the projection screen to be transversely unfolded; blowing of left and right wind directions to the projection screen is overcome; through holes are formed in a wood plate arranged in the middle, the wood plate is installed in cooperation with a draught fan, wind blown by the draught fan is parallel to the wood plate, the air flowing speed on the back face of the wood plate is increased, the projection screen is adsorbed, shaking of the projection screen is further prevented, it is guaranteed that after holographic projection of the unfolded projection screen, pictures are stable, and the watching effect of audiences is guaranteed.

Description

technical field [0001] The invention relates to the technical field of holographic projection, in particular to a combined truss for a holographic projection curtain wall. Background technique [0002] Holographic projection technology refers to the technology that uses the principle of interference to record and reproduce the real three-dimensional images of objects. With the continuous use of technology, the concept of holographic projection is extended to stage performances, exhibitions and other commercial activities. Holographic projection equipment includes holographic projectors, holographic Projection screen, holographic projection transparent film, holographic projection content production, etc. [0003] In outdoor stage performances, holographic projection equipment needs to be built. The holographic projection screen is built with a combined truss to form a 16:9 door, and then the roll-shaped holographic projection screen is fixed to the beam of the truss door. L...
