Display device for ethnology teaching

Abstract

The invention relates to the technical field of teaching display devices, and particularly relates to a display device for ethnology teaching. The display device for ethnology teaching comprises a support base, wherein the bottom surface of the support base is provided with a plurality of universal wheels. The display device for ethnology teaching is characterized in that a plurality of clamping blocks fixedly connected with a first connecting rod are installed on a display board, a push block fixedly connected with a second connecting rod is installed above each clamping block, opposite side surfaces of the two connecting rods are provided with a row of sawteeth, and opposite movements of the two connecting rods are realized through a gear between the two connecting rods, so that movements of the clamping blocks are realized through pushing a push rod, and materials in ethnology teaching are clamped and fixedly or quickly taken down. Node clamping and fixing for the second connecting rod are realized through a clamping rod on the second connecting rod, and swinging for the clamping rod is realized through a pull rod above the push blocks, so that release for the second connecting rod is realized, and automatic return of the second connecting rod is realized. The materials in ethnology teaching can be fixed and displayed or taken down and replaced conveniently according to the mode, and the display device for ethnology teaching is very convenient and practical.
