Abstract

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.
