Example

As shown in FIG. 1 to FIG. 4 , the present embodiment discloses a textbook frame diagram shorthand teaching aid, which includes a support board 100 and a demonstration board 200 .

The bottom of the support plate 100 is provided with a main bracket 110, and the support plate 100 is a whiteboard or a blackboard, which is convenient for teachers to be equipped with blackboard writing to assist in explaining the knowledge of the frame diagram, with high flexibility and improved learning efficiency for students. The demo board 200 is slidably connected to the support board 100. Specifically, slide rails 120 are provided on the upper and lower sides of the front side of the support board 100, and sliders 250 matched with the slide rails 120 are provided on the upper and lower sides of the back of the demo board 200, so that The demo board 200 can reciprocate along the arrangement direction of the slide rail 120 . Through the above sliding connection method, the support board 100 and the demonstration board 200 can be unfolded and folded. When the teacher needs to further explain the content of the demonstration board 200 during teaching, he can slide the demonstration board 200 to write on the blackboard in the support board 100. teaching. When the demo board 200 reciprocates along the slide rail 120 , a foldable sub-bracket 260 is detachably installed at one end edge of the back of the demo board 200 away from the support board 100 . The sub-bracket 260 is used to assist the supporting plate 100 to prevent the entire shorthand teaching aid from tipping over due to an unbalanced center of gravity. In order to facilitate the movement of the entire teaching aid and facilitate the movement, universal wheels 300 are installed at the bottoms of the main support 110 and the auxiliary support 260 .

The demo board 200 includes a magnetic base plate 210 and a moving grid plate 220 that is fixedly connected to the magnetic base plate 210. Specifically, the magnetic floor 210 can be slidably connected to the support plate 100 through fixed connection methods such as welding, screw connection, and plug connection. The running grid plate 220 is a grid plate formed by a combination of a plurality of first longitudinal grid bars and a plurality of second longitudinal grid bars intersecting with the first longitudinal grid bars.
