Description

a projection mechanism

technical field

The utility model relates to the technical field of projectors, in particular to a projection mechanism.

Background technique

A projector, also called a projector, is a device that can project images or videos onto a screen. It can be connected to a computer, VCD, DVD, BD, game console, DV, etc. through different interfaces to play the corresponding video signal. Projectors are becoming more and more common now, and are used in businesses, schools and homes. The projector used at home is a portable small projector, which itself does not have the function of angle adjustment. It is necessary to adjust the angle of the projector lens when projecting. At the same time, some thick things such as books are placed on the side of the bottom of the projector, so as to raise the side of the projector and change the angle of the lens. Insufficient, because it relies on foreign objects to raise one end of the projector, and does not fix the projector itself, which makes the height of the projector have certain limitations. Once one end is too high, the projector tends to move to the lower side It is slippery, and there is a phenomenon that it cannot meet the angle adjustment needs of movie viewers. Contents of utility models.
