Coordinate plate position adjusting device for drawing plate for mathematical teaching and adjusting method

Abstract

The invention discloses a coordinate plate position adjusting device for a drawing plate for mathematical teaching and an adjusting method. The coordinate plate position adjusting device comprises a fixing plate, a transparent plate, a mounting plate, a coordinate plate, a connecting block, ejector rods and a linkage assembly; the transparent plate is fixedly arranged on the front side of the fixing plate, moreover, an interval is formed between the transparent plate and the fixing plate, the mounting plate is movably arranged on the fixing plate, and is located in the interval between the transparent plate and the fixing plate, the connecting block is fixedly arranged in a containing space, an inserting groove for allowing a pounding rod mechanism to move horizontally is formed in the connecting block, the ejector rods are distributed on the two sides of the connecting block, one ends of the ejector rods horizontally penetrate through the coordinate plate and are in contact with the transparent plate, the other end of each ejector rod is connected with an elastic assembly for tightly pressing and fixing the corresponding ejector rod to the transparent plate, the input end of the linkage assembly is movably arranged in the inserting groove, when the pounding rod mechanism acts on the input end of the linkage assembly, the output end of the linkage assembly can act on the ejector rods and drive the ejector rods to move to overcome the pressing force of the elastic assembly so as to release pressing and fixing on the transparent plate.

Description

technical field [0001] The invention relates to the technical field of drawing tools for mathematics teaching, in particular to a coordinate plate position adjusting device and an adjusting method of a drawing plate for mathematics teaching. Background technique [0002] In the teaching process of deriving mathematical formulas in college mathematics, in order to allow students to more intuitively understand the meaning expressed by the formulas, it is necessary to draw curves corresponding to the mathematical formulas. However, in the current teaching process, when drawing, generally The teacher draws freehand on the blackboard. Because it is troublesome to draw the coordinate system on the blackboard, the coordinate system is generally not drawn when drawing, resulting in irregular drawings, which cannot express what they want well.

[0002] In the teaching process of deriving mathematical formulas in college mathematics, in order to allow students to more intuitively understand the meaning expressed by the formulas, it is necessary to draw curves corresponding to the mathematical formulas. However, in the current teaching process, when drawing, generally The teacher draws freehand on the blackboard. Because it is troublesome to draw the coordinate system on the blackboard, the coordinate system is generally not drawn when drawing, resulting in irregular drawings, which cannot express what they want well. The meaning of representation; in order to solve the above problems, some patent documents now propose solutions to the above problems, one of which is to place a coordinate board on one side of the blackboard and draw on the coordinate board, but due to the variety of university mathematics formulas, There are also a lot of pictures needed. Therefore, if they are drawn together, the pictures and formulas cannot be well corresponded one by one, which will cause misunderstandings in the teaching process and the effect is not good. It is a problem to be solved to draw a picture next to the formula and make the formula and the picture correspond one-to-one in terms of positional relationship
