3D holographic projection equipment convenient to install and maintain and used for11 cultural transmission, exhibition and display

Abstract

The 3D holographic projection equipment comprises a base, a mounting box is arranged at the top end of the base and fixed to the top end of the base through bolts, and a hydraulic rod is arranged in the base and fixedly connected with the base through bolts; and a fixed box is arranged on one side of the hydraulic rod in the base. By arranging the motor and the first main bevel gear, when the device needs to be moved to an exhibition stand, the motor and the second main bevel gear are controlled to rotate through the rotating shaft, and the second main bevel gear drives the third screw to rotate through the second gear, so that the supporting legs are driven to move upwards; meanwhile, a second gear drives a second screw to rotate through a first gear, the second screw pushes a rotating wheel to move downwards through a push rod, the supporting legs are separated from the ground, the rotating wheel makes contact with the ground, and the projection device can be pushed.

Description

technical field [0001] The invention relates to the field of projection devices, in particular to a 3D holographic projection device for cultural communication, exhibition and display that is easy to install and maintain. Background technique [0002] Holographic projection technology is a kind of 3D technology. It originally refers to the technology of recording and reproducing real three-dimensional images of objects by using the principle of interference. Later, with the guidance of science fiction movies and commercial promotion, the concept of holographic projection gradually extends to stage performances, exhibitions, etc. In commercial activities, the holography we usually know is often not a holographic projection in the strict sense, but a kind of holographic projection technology that uses methods such as Pepper's phantom and edge blanking to achieve 3D effects. [0003] At present, when it is used in practice, the first problem is that the traditional holographic ...

AI Technical Summary

Problems solved by technology

[0003] At present, when it is used in practice, the first problem is that the traditional holographic projection device for exhibition is mostly installed and fixed by bolts, which is time-consuming and laborious. The demand for mobile installation is low in practicability and adjustability. The second problem is that when transported to the exhibition, the holographic projection device takes up a large space and is exposed to the outside, and the projection film is mostly fragile products, which are easy to be touched and squeezed. Damaged, inconvenient for protection, transportation and storage. Problem 3. The holographic projection lens is used for a long time, and it is easy to adhere to dust, which is not easy to clean, resulting in poor projection effect, and it is not easy to clean automatically.
