Description

Technical Field

[0001] The utility model relates to the technical field of projection devices, and particularly relates to an interactive projection device. Background Technique

[0002] Projection refers to using a group of light rays to project the shape of an object onto a plane, which is called projection. The image obtained on this 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 rays is perpendicular to the projection plane, and the projection whose projection center line is not perpendicular to the projection plane is called oblique projection. A projector, also known as a projection machine, is a device that can project images or videos onto a screen and is widely used in homes, offices, schools, and entertainment venues.

[0003] The existing utility model patent with the application number: CN202020813905.1 proposes a wall interactive projection device. The wall interactive projection device described in the utility model can achieve excellent protection effects, reduce the phenomenon of damage to the holographic projector caused by external factors, and at the same time can also achieve better heat dissipation effects, which is more conducive to use.

This connection method is very troublesome to operate, and the projector cannot be conveniently removed for maintenance. Moreover, the projector often needs to be adjusted in position during projection, and the process of angle adjustment is relatively cumbersome, reducing the practicability of the device. Therefore, an interactive projection device is provided to solve the above problems. Content of the Utility Model
