Holographic projection device capable of jacking and rotating holographic projection screen

Abstract

The invention discloses a holographic projection device capable of jacking and rotating a holographic projection screen, and relates to the technical field of holographic projection devices. The holographic projection device comprises an outer framework, a jacking rotating device and a holographic projection device, wherein the outer framework comprises a base frame and a top plate; four groups ofguide cylinders are arranged on the surface of the U-shaped frame; a guide rod is arranged in each guide cylinder; a guide rail is arranged in the upper surface of a lifting plate; a sliding block isarranged on the guide rail; a movable plate is arranged on the sliding block; a fixed base is arranged at the front end of the guide rail; a rotating base is arranged in the middle of the lifting plate; a rotating rod is arranged on the rotating base; a rack is fixed on the upper surface of the movable plate; a gear is arranged on the rotating rod in a sleeved mode, and the rack is in meshed transmission with the gear; the front end of a push rod of the electric push rod II is fixedly connected with the middle of the lower surface of the lifting plate; and a holographic projector is fixed onthe lower surface of the top plate. The whole device is simple and compact in structure and capable of rotating and lifting and adjusting the holographic projection screen, the adjusting effect is good, and the ornamental effect is improved.

Description

technical field [0001] The invention relates to the technical field of holographic projection devices, in particular to a holographic projection device with a holographic projection screen that can be lifted and rotated. Background technique [0002] Holographic projection technology, also known as virtual imaging technology, is a technology that uses the principles of interference and diffraction to record and reproduce real three-dimensional images of objects. The holographic projection screen of some holographic projection equipment is generally placed on a fixed table, and the adjustment of the rotation angle and height cannot be adjusted. Therefore, a simple structure is developed, which can rotate and lift the holographic projection screen. It is very necessary to improve the holographic projection device with good adjustment effect and improved viewing effect.
