The invention discloses a multi-directional moving device of a projection display device, and relates to the technical field of projection display. The multi-directional moving device of the projection display device is characterized in that a plurality of mounting screws are screwed on a base plate through threads, a suspender is fixed on the lower surface of the base plate, the lower end of thesuspender is fixed on a sliding block, the sliding block is slidably arranged on a guide rail, the guide rail is fixed on a bottom plate, first ferrite ceramics are fixed to the lower surfaces of thetwo ends of the bottom plate, the first ferrite ceramics are movably clamped in a circular groove formed in the upper surface of a mounting ring, screw rod seats are fixed to the two ends of the guiderail, the two ends of a screw rod are screwed into the screw rod seats through bearings, and one end of the screw rod sequentially penetrates through the lower end of the suspender and the screw rodseat on one side and then is connected with an output shaft of a motor. The multi-directional moving device of the projection display device can meet the use requirements of different display curtainsin multiple distances, is high in adjustability, and widens the application range.
Description
technical field [0001] The invention relates to the technical field of projection display, in particular to a multi-directional mobile device for a projection display device. Background technique [0002] A projection display device generally includes a projector and a display screen. At present, the distance between the suspended projector and the display screen is fixed to ensure that the content projected onto the display screen has better brightness, resolution and uniformity. Therefore, after a projector is installed and fixed in position, it is only suitable for a display screen at a distance matched with it. It cannot be applied to display screens at multiple distances, which limits its scope of application. Contents of the invention [0003] The object of the present invention is to address the defects and deficiencies of the prior art, and provide a rationally designed multi-directional mobile device for projection display devices, which can meet the use of diff...
