Abstract

The invention relates to the technical field of projectors, in particular to a multimedia projection system. The system comprises: a projector; an accommodating box, an opening is formed in one side,facing the ground, of the accommodating box; a baffle which is used for bearing the projector and can move in the vertical direction; one end of a shear fork lifting frame is assembled with the accommodating box, the other end of the shear fork lifting frame is assembled with the baffle, and the shear fork lifting frame comprises multiple connecting rods. A driving assembly which is installed in the accommodating box and used for driving the shear fork lifting frame to be unfolded or folded in the vertical direction, and the driving assembly comprises a winding reel installed in the accommodating box; reversing wheels which are mounted at two ends of the connecting rod; one end of a winding rope is fixed to the baffle, the other end of the winding rope is fixed to the winding reel after being reversed along the reversing wheel, and winding is conducted through the winding reel; and a driving piece which is assembled with the winding reel and used for driving the winding reel to rotateso as to wind and unwind the winding rope. When the projector is not used, the projector can be stored, so that dust accumulation on the projector can be reduced, and the service life of the projectoris prolonged.

Description

technical field [0001] The invention relates to the technical field of projectors, in particular to a multimedia projection system. Background technique [0002] A projector, also known as 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 and DV through different interfaces to play the corresponding video signal. It is usually used in scenes such as teaching and meetings, but the existing projectors are usually fixed and suspended on the ceiling without protection measures, resulting in easy accumulation of dust on the projector, thereby affecting the service life of the projector. Contents of the invention [0003] Therefore, the technical problem to be solved by the present invention is to overcome the defect that the projector is fixedly installed in the prior art, causing dust to accumulate on the projector and affecting the service life of the projector, so as to provide a multimedia...
