Abstract

According to the technical scheme, the show window advertisement projection system for propaganda is characterized by comprising a base and projection cloth, the bottom of a sliding plate is fixedly connected with a first fixing plate through a first fixing screw, a fixing mechanism is arranged on the sliding plate, and a second gear is arranged at the bottom of a rotating rod; a rotating rod is rotated to enable a second gear to drive a first gear to rotate, then a threaded column is rotated, a sliding plate slides on a sliding groove, the height of the projector can be conveniently adjusted, the projection angle can be conveniently adjusted, sliding of the sliding plate is limited through a fixing mechanism, and then the projector is fixed. The projector can be disassembled conveniently by disassembling the first fixing screw from the first fixing plate, and the projector, the second gear and the supporting column can be disassembled conveniently by disassembling the second fixing screw from the second fixing plate, so that the projector, the second gear and the supporting column can be disassembled and stored conveniently.

Description

technical field [0001] The invention relates to the field of advertisement projection, in particular to a display window advertisement projection system for publicity. Background technique [0002] Projection refers to the use of a set of rays to project the shape of an object onto a plane, called "projection". The image obtained on this plane is also called "projection". Projection can be divided into orthographic and oblique. Orthographic projection means that the center line of the projection line is perpendicular to the projection plane, and the projection center line is not perpendicular to the projection plane, which is called oblique projection. [0003] However, the existing display window advertising projection system for publicity is inconvenient to adjust the height of the projector, to perform projection, and to disassemble and store the projection device. Contents of the invention [0004] In view of the problems mentioned in the background art, the object ...
