[0020] The utility model has the following beneficial effects:

[0021] 1. Compared with the prior art, the present invention relates to a hidden projector structure for a conference room. The present invention comprises a motor, a double-threaded screw, a movable block, a connecting bar, an upper plate, a connecting column, a ceiling supplementary plate, a projector, a first groove, and a ceiling. The motor drives the double-threaded screw to rotate, thereby driving the movable blocks to move closer or farther away from each other, thereby causing the connecting bar to deflect, thereby controlling the upper plate to move up and down, thereby controlling the connecting column, the ceiling supplementary plate, and the projector to move up and down. When the projector is needed, the projector is placed at the lowest movable position to start projection. When the projector is not needed, the projector is retracted into the first groove. At this time, when viewed from below, the ceiling supplementary plate and the ceiling are in contact with each other, without affecting the overall aesthetics. Compared with the existing projector structure for a conference room, when it is installed, it is generally placed directly on a table or cabinet or hung on the ceiling. The position of the projector installed on the ceiling is fixed and cannot be hidden, making the conference room look less beautiful. The present invention relates to a hidden projector structure for a conference room. When the projector is not in use, the projector can be hidden and stored, without affecting the overall aesthetics of the conference room.

[0022] 2. Compared with the prior art, the hidden projector structure for a conference room comprises a projector, a movable frame, a first latch, a second latch, a first inclined slot, a second inclined slot, a first limiting block, a second limiting block, a first spring, a second spring, a first limiting slot, a second limiting slot, a ceiling supplementary plate and a slider. When the projector needs to be removed, the movable frame is pulled forward, thereby moving the first latch and the second latch forward. Due to the presence of the first inclined slot and the second inclined slot, the two first limiting blocks and the two second limiting blocks are brought close to each other, which causes the first spring and the second spring to move forward. The two springs are compressed, and the first limit block and the second limit block are respectively disengaged from the first limit groove and the second limit groove. At this time, the projector can be easily removed from the ceiling supplementary plate. When the projector needs to be installed, the same operation is performed to pull the movable frame, and finally the two first limit blocks and the two second limit blocks are close to each other. The first spring and the second spring are compressed. At this time, the projector is placed in the specified position, and the movable frame is released. Finally, the first spring and the second spring rebound, and the first limit block and the second limit block re-fix the slider, that is, fix the projector, which makes it easier to inspect and repair the projector.
