Holographic projection equipment capable of being quickly folded and unfolded

Abstract

The invention discloses holographic projection equipment capable of being quickly folded and unfolded, which is provided with an equipment shell, and a sealing baffle cover is hinged to the top of the equipment shell; comprising a fixed cylinder fixed to the center of the inner bottom surface of the equipment shell, a guide rod movably penetrates through the top of the fixed cylinder, a display stand is arranged at the top of the guide rod, and a supporting rod movably penetrates through the edge of the display stand; the guide plate is fixed at the edge of the display stand, and a first ball is embedded into the end part of the guide plate; and the movable shaft movably penetrates through the side wall of the equipment shell, and a movable block is fixed to one end of the movable shaft. According to the holographic projection equipment capable of being rapidly folded and unfolded, the holographic projector can be rapidly and stably displayed and stored so that the holographic projector can be protected when the holographic projector is not used, air can be blown to the holographic projector in real time in the display process, heat can be dissipated, dust adhesion can be avoided, and the viewing definition can be improved.

Description

technical field [0001] The invention relates to the technical field of holographic projection, in particular to a rapidly retractable holographic projection device. Background technique [0002] Holographic projection is a manifestation of the increasingly mature application of 3D technology. Through the three-dimensional image technology, the two-dimensional plane information in the traditional technology can be converted into three-dimensional information that is more fully observed by the naked eye. In the existing technology, this type of projection equipment is mostly used for The display of goods or other items, so the requirements for high-transparency glass in the equipment are relatively high. For example, a holographic projection display device with publication number CN215067737U includes a display box, a holographic projector inside the display box, and a holographic projector installed in the display box. The projection hole at the top of the box, the side of th...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a holographic projection device that can be quickly retracted to solve the above-mentioned background technology. It is proposed that most of the traditional holographic projection devices are directly placed on the display stand, which is inconvenient to display and store according to the needs, and the holographic projection device is in During the display process, the clarity of viewing will be affected by dust, and the traditional holographic projection equipment lacks the structure of soot blowing during the display process
