The invention discloses a projection device for multimedia teaching and a using method of the projection device. A box body is included, and the top of the box body is fixedly connected with a plate body; the inner side of the plate body is provided with a slide groove; an inner cavity of the slide groove is in sliding connection with a sliding block; the top of the sliding block is fixedly connected with a connection rod; and the top of the connection rod is fixedly connected with a top plate. According to the device, a motor is started through a switch, an output shaft of the motor drives adriving gear to rotate, and the driving gear drives a driven gear to rotate; the driven gear drives a rotating shaft to rotate, and the rotating shaft drives a first bevel gear to rotate; the first bevel gear drives a second bevel gear to rotate; the second bevel gear drives a rotating rod to rotate in a bearing pedestal; the rotating rod drives a disk to rotate; meanwhile, the rotating shaft drives a shell to rotate, and the shell drives a projector to rotate, so that the projection angle of the projector is adjusted; and scales on the disk and the positions corresponding to pointers are memorized so that the purposes that adjusting is convenient and reusing is convenient are achieved.
Description
technical field [0001] The invention belongs to the field of multimedia teaching, and in particular relates to a projection device for multimedia teaching and a method for using the same. Background technique [0002] Multimedia teaching means that in the teaching process, according to the characteristics of teaching objectives and teaching objects, through teaching design, rational selection and use of modern teaching media, and organic combination with traditional teaching methods, to jointly participate in the whole process of teaching, with the role of a variety of media information. For students, form a reasonable teaching process structure and achieve the optimal teaching effect. Multimedia teaching requires the use of corresponding multimedia equipment, such as projection devices, projectors, also known as projectors, which can project images or videos onto the screen. The equipment on the projector can be connected to the computer, VCD, DVD, BD, game console, DV, etc...
