Abstract

The invention provides a base with an adjustable inclination angle and a projection device. The base with the adjustable inclination angle is applied to the projection device, the projection device is provided with a projection body, and the base with the adjustable inclination angle comprises a fixed plate, a rotating plate and an adjusting piece. The rotating plate is fixedly connected to the projection body and is in pin joint to the fixed plate, the adjusting piece comprises a spiral track, and the adjusting piece penetrates through the fixed plate and the rotating plate and forms interference with the rotating plate. During use, the adjusting piece is rotated to enable the spiral track to drive the rotating plate and the projection body to rotate, so that the included angle of the rotating plate and the projection body relative to the fixed plate is adjusted so as to adjust the inclination angle of the projection device, and therefore by simply rotating the adjusting piece, the inclination angle of the base can be adjusted, and the image projection angle of the projection device can be changed.

Description

technical field [0001] The invention relates to a base with adjustable inclination and a projection device, in particular to an adjustable base with adjustable projection angle and a projection device. Background technique [0002] At present, projectors are widely used in various occasions, such as office meetings, school education, home theaters and entertainment venues. Projectors are no longer just used to play report slides in classrooms or meeting rooms, but are closely related to entertainment, life, fashion, and intelligence. One of the conveniences is that they can be projected anywhere. All you need is a curtain, a wall, or even a ceiling, and the projector can project images. In addition, if the user needs to change the position of the projected image, the general method is that the user manually moves the body of the projector to adjust. As a result, the convenience of operation is affected. [0003] Therefore, it is necessary to design a novel tilt-adjustable...
