[0002] A filter wheel refers to a rotating filter device used in projectors or other optical devices. It is usually composed of several filter sheets of different colors. These filter sheets are installed on a turntable. By rotating different colored filter sheets into the optical path, the filter wheel can control the color of the light passing through, so that the projected image presents the required color effect.

[0003] The filter sheet wheel will be fixed at a specific position on the turntable, and the entire turntable will be controlled to rotate by a rotating device, usually a motor. The filter sheet is fixed at a specific position on the turntable. Usually, screws are used to firmly connect the filter sheet to the turntable to prevent displacement or falling off during rotation. However, the filter sheet will be worn and damaged during use. At this time, the installed screws need to be disassembled. The screw structure is small and the number is large. The process of disassembling and replacing the filter sheet is very cumbersome. Therefore, those skilled in the art have provided an installation structure of a filter wheel to solve the problems raised in the above background technique. Content of the Utility Model
