Abstract
An adapter assembly and a projection device are provided. The projection device includes a device body, an illumination system, a light valve, the adapter assembly, and a projection lens. The light valve is disposed in the device body to convert the illuminating beam provided by the illumination system into an image beam. The projection lens includes a plurality of protruding claws that surround a circumferential surface of a main body and protrude along the radial direction. The adapter assembly includes a first ring member, a rotating plate, and a second ring member sequentially disposed along the axial direction of the adapter assembly. When the projection lens is assembled to the adapter assembly, the rotating plate rotates to limit the protruding claws within a limiting assembly space formed by the first ring member and the second ring member to lock the projection lens to the device body.
