Abstract

The invention relates to the technical field of teaching aids, and discloses a graphic display device for mathematics teaching, which comprises a bottom plate, mounting rods are symmetrically and fixedly connected to the upper surface of the bottom plate, a double-sided blackboard is arranged between the two mounting rods, the tops of the opposite sides of the two mounting rods are rotationally connected with turnover rods I through rotating shafts, and the turnover rods I are rotationally connected with turnover rods II through rotating shafts. The bottoms of the opposite sides of the two first overturning rods are rotationally connected with connecting rods through rotating shafts correspondingly, the opposite ends of the two connecting rods are rotationally connected with the two sides of the double-face blackboard through rotating shafts correspondingly, and a second overturning rod is arranged between the mounting rod and the double-face blackboard. The bottoms of the opposite sides of the two second overturning rods are rotationally connected with the opposite sides of the two mounting rods through rotating shafts correspondingly. The turnover rods I, the connecting rods and the turnover rods II which are arranged on the two mounting rods above the bottom plate are matched with the double-sided blackboard, so that the double-sided blackboard can be turned over during use.

Description

technical field [0001] The invention relates to the technical field of teaching tools, in particular to a graphic display device for mathematics teaching. Background technique [0002] Blackboard refers to a plane that can be repeatedly written with chalk, and is mostly used for teaching. In the process of mathematics teaching, teachers usually need to draw graphics on the blackboard for students to watch for the convenience of teaching. [0003] Most of the existing blackboards are single-sided, so teachers often need to wipe the blackboard after writing on one side. Here we propose a graphic display device for mathematics teaching. Contents of the invention [0004] (1) Solved technical problems [0005] Aiming at the deficiencies of the prior art, the present invention provides a graphic display device for mathematics teaching, which solves the problems raised in the background above. [0006] (2) Technical solution [0007] In order to achieve the above object, the...
