技术领域Technical Field

本实用新型涉及教学设备技术领域,具体为一种经济学教学对比展示板。The utility model relates to the technical field of teaching equipment, in particular to an economics teaching comparison display board.

背景技术Background Art

在经济学的教学课堂上,教师通常需要在展示板上绘画各类教学图表,然后将不同的图表重叠进行对比,可以让学生直观地感受各类图表的数据变化。In economics classes, teachers usually need to draw various teaching charts on the display board, and then overlap different charts for comparison, so that students can intuitively feel the data changes in various charts.

经检索,专利申请号为CN202120528037.7的申请书中,公开了一种经济类数据对比分析教学展示板,其包括底部支座和书写机构,其中,书写机构固定于底部支座上方且包括第一固定框架以及固定于第一固定框架内的第一书写板,书写机构还包括第二书写板,该第二书写板为透明材料件,第一固定框架的上沿设有枢转轴,第二书写板的上部设有能够与枢转轴配合的枢转孔,使得第二书写板能够转动覆盖在第一书写板的第一书写面;After searching, the application with patent number CN202120528037.7 discloses an economic data comparison and analysis teaching display board, which includes a bottom support and a writing mechanism, wherein the writing mechanism is fixed above the bottom support and includes a first fixed frame and a first writing board fixed in the first fixed frame, and the writing mechanism also includes a second writing board, which is a transparent material piece, and a pivot shaft is provided on the upper edge of the first fixed frame, and a pivot hole capable of cooperating with the pivot shaft is provided on the upper part of the second writing board, so that the second writing board can rotate to cover the first writing surface of the first writing board;

虽然该经济类数据对比分析教学展示板通过第二书写板能够绕着枢转轴为旋转,便于使第二书写板覆盖在第一书写板的前方,继而可以对两个书写板上的数据进行对比,但是该经济类数据对比分析教学展示板在使用时,第一书写板和第二书写板始终保持重叠,不便于教师对第一书写板和第二书写板上的数据进行单独的讲解分析。Although the economic data comparative analysis teaching display board can rotate around a pivot axis through the second writing board, so that the second writing board can cover the front of the first writing board and then compare the data on the two writing boards, when the economic data comparative analysis teaching display board is in use, the first writing board and the second writing board always remain overlapping, which is not convenient for teachers to conduct separate explanations and analyses of the data on the first writing board and the second writing board.

因此,我们提出了一种经济学教学对比展示板。Therefore, we propose a comparative display board for economics teaching.
