The invention discloses a miniature projector with a projection angle regulation device, which comprises a shell, a projection component, a lifting connecting piece and a rotating component, wherein the projection component comprises a projection module and a projection module bracket which are connected in a rotating way; the rotating component comprises an eccentric wheel fixing frame and an eccentric wheel; the eccentric wheel fixing frame is provided with a through hole adapted to an inner cylinder of the eccentric wheel; the inner cylinder of the eccentric wheel is extended out of the eccentric wheel fixing frame; the eccentric wheel fixing frame is fixed in the shell; the projection component, the lifting connecting piece and the rotating component are arranged in the shell; the lifting connecting piece is arranged between the projection component and the rotating component; and the upper end of the lifting connecting piece is in contact with the projection component, while a lower end is in contact with an outer wheel of the eccentric wheel. The rotating component is provided with the eccentric wheel and the outer wheel is driven to rotate by rotating the inner cylinder of the eccentric wheel to further ascend and descend the projection component, thereby achieving the effect of regulating a projection angle.
Description
technical field [0001] The invention relates to a projector, in particular to a miniature projector with a projection angle adjustment device. Background technique [0002] Because the existing projection computer projection lens is fixed on the projection computer, there is no projection angle adjustment mechanism of the projection lens, when the user needs to use the projection computer to project on the projection screen, it is necessary to adjust the position or angle of the entire projection computer to adapt Projection screens, such as placing books or gaskets between the projection computer and the supporting desktop, or replacing the supporting desktop, however, due to the thickness or height of the books, gaskets and desktop, it is more difficult to adjust some small angles Realized, resulting in failure to reach a suitable imaging angle and affecting users viewing projected images.
