The invention discloses intelligent teaching demonstration equipment for art teaching. The intelligent teaching demonstration equipment comprises four supporting legs and a circular plate, wherein the tops of the four supporting legs are fixedly connected with a mounting cylinder; the mounting cylinder is internally provided with an adjusting mechanism enabling the circular plate to ascend or descend; the adjusting mechanism comprises a screw rod, and the screw rod is rotatably connected to the inner bottom of the mounting cylinder; the outer wall of the screw rod is in threaded connection with a screw rod sleeve; the outer wall of the screw rod sleeve is fixedly connected with two mounting frames; the tops of the two mounting frames are fixedly connected with the bottom of the circular plate; the outer wall, located below the two mounting frames, of the screw rod sleeve is fixedly connected with a limiting block; a plurality of limiting grooves are formed in the inner wall of the mounting cylinder in a circumferential array mode; and the limiting block is connected with the inner walls of the limiting grooves in an up-down sliding mode. Through the cooperation of the above structures, a diversified and rich light environment can be constructed for teachers and students, demonstration and explanation of the teachers and observation of the students are facilitated, and the students can conveniently cultivate the sense of space and the sense of light.

The invention discloses a lifting platform for a teaching instrument and an application method of the lifting platform and relates to the technical field of tools for the teaching instrument. The lifting platform comprises a bottom plate and a top plate. Two lifting mechanisms are symmetrically installed between the bottom plate and the top plate. The top face of the bottom plate is provided witha set of sliding ways. Each lifting mechanism comprises an oblique plate, a supporting rod and two symmetrically arranged supporting plates, wherein the close faces of the two supporting plates are provided with rectangular grooves, the bottom face of the supporting plate close to the bottom plate is fixedly provided with a set of sliding blocks matched with the sliding ways, the top face of the other supporting plate is rotationally connected with the top face of the top plate through a plurality of rotating bodies, and the two ends of the oblique plate are hinged to different end side wallsof the upper rectangular groove and the lower rectangular groove correspondingly. According to the lifting platform, the height adjustment of the top plate and the bottom plate is achieved through thelifting mechanisms, the space adjustment of the bottoms of the lifting mechanisms is achieved through the sliding fit of the sliding blocks on the supporting plates and the sliding ways on the bottomplate, teaching demonstration of a teacher and student observing can be facilitated, and the learning efficiency of a student is guaranteed.

The invention provides a classroom interactive teaching demonstration device. The classroom interactive teaching demonstration device comprises a device body, a baffle is fixedly installed at the bottom of the device body, a driving motor is fixedly installed at the bottom of the baffle, a lead screw is fixedly installed on an output shaft of the driving motor, a supporting plate is movably installed at the top of the baffle, and the supporting plate is movably installed on the lead screw through a lead screw nut. According to the classroom interactive teaching demonstration device, the lead screw is driven by the driving motor to lift and store a first display screen, a second display screen and a third display screen, so that the phenomenon that the display screens are damaged due to accidents can be avoided; a left stepping motor and a right stepping motor can drive rotating shafts to adjust the angle between the first display screen and the second display screen and the angle between the first display screen and the third display screen, and the first display screen, the second display screen and the third display screen can display different teaching contents, so that the teaching quality can be improved; and a teacher can conveniently know the learning condition of students through a camera.
