[0002] Projection refers to the use of a set of light rays to project the shape of an object onto a plane, which is called "projection". The image obtained on the plane is also called "projection". Projection can be divided into orthographic projection and oblique projection. Orthographic projection means that the center line of the projection line is perpendicular to the projection plane, and the projection center line is not perpendicular to the projection plane, which is called oblique projection. Projection is also called true shadow, a kind of object shadow; it refers to an area where the light of the light source is blocked by the object. With the continuous development of science and technology, 3D dynamic projection technology is becoming more and more advanced. For the display and explanation of art objects, 3D dynamic projection devices are often used to display art works. However, traditional 3D dynamic projection devices are usually hoisted to connect the projection device to the mounting frame by bolts. Since the hoisting has a certain height and multiple bolts need to be tightened and fixed, the installation efficiency is slow. Therefore, a 3D projection device is proposed to solve the above technical problems. Utility Model Content
