Abstract

The invention discloses a hidden projection screen, which comprises a bottom plate arranged at one side of a wall body, wherein the wall body is provided with a placement groove corresponding to the bottom plate in position, two first sliding blocks are symmetrically arranged at the lower side of the bottom plate, the inner bottom of the placement groove is provided with first sliding slots corresponding to the first sliding blocks, the inner side wall of each first sliding slot is rotatably connected with a screw, each first sliding block is in threaded connection with the corresponding screw, one end of the screw penetrates through the inner side wall of the corresponding first sliding slot and is fixedly connected to an adjustment knob, two fixing plates are symmetrically arranged at the upper side of the bottom plate, the opposite sides of the two fixing plates are provided with connecting shafts respectively, and each fixing plate is provided with an insertion opening corresponding to the connecting shaft. The hidden projection screen is simple in structure and convenient to use, and reduces the occupation for the space through setting the placement groove used for placing the projection screen on the wall body, thereby being more clean and beautiful indoors, preventing a curtain from being exposed in the air for a long time at the same time, and prolonging the service life.

Description

technical field [0001] The invention relates to the technical field of projection screens, in particular to a hidden projection screen. Background technique [0002] Projection screens are used in movies, offices, home theaters, large conferences, etc. to display images and video files. The size of the projection screen in different spaces is also different. For example, if there are many people watching or viewing horizontally, it is better to choose a screen with a wide viewing angle and low gain. The gain screen helps to improve the contrast of the screen, so that the gray scale of the image is increased, the color is vivid, and the image is impressive. [0003] Existing projection screens generally use glass bead screens, which are installed on one side of the wall and are in direct contact with the outside. The small glass beads on the glass bead screen are exposed to the air and easily oxidize and turn yellow, thereby affecting the projection effect. It cannot be res...
