Angle-adjustable demonstration board for mathematical plotting

Abstract

The invention discloses an angle-adjustable demonstration board for mathematical plotting. The board comprises a main body, an angle adjusting mechanism, a paper pressing mechanism, a demonstration board body, a connecting box body, an LED lamp, a writing board and a pin shaft; the paper pressing mechanism is internally provided with a mounting base plate, a first rotating mounting base, a secondrotating connecting frame, a second pin shaft, a cross frame and a paper pressing plate, wherein a mounting base plate is arranged at the bottom of the first rotating mounting base, and a plurality ofmounting holes are uniformly formed in the mounting base plate; and threaded connecting holes corresponding the mounting holes are formed in the demonstration area below the mounting base plate, andthe mounting base plate is arranged on the demonstration area through screws. The angle-adjustable demonstration board is convenient to use, in the using process, when paper is required to be pressed,the transverse frame is pulled up through a third pull handle, and the paper pressing plate leaves the demonstration board main body; then the paper is plugged to the upper portion of the demonstration area, and when the cross frame is rotated, the paper pressing board is in contact with the paper, so that the paper is fixed; and a second paper pressing block which is arranged can be used for assisting the paper pressing.

Description

technical field [0001] The invention relates to the field of mathematics, in particular to a display board for mathematical drawing whose angle can be adjusted. Background technique [0002] At present, in the process of learning mathematics, one will learn mathematical modeling, and drawing is required in the learning process of mathematical modeling. Traditional mathematical modeling is used as a drawing device, and its functions are relatively single. To adjust, it is very inconvenient for teachers to draw and teach. In addition, the existing drawing board cannot clamp the paper well, and it is easy for the user to move or misplace the paper when using it, which affects the quality of the user's drawing and reduces the efficiency of the user's drawing. In addition, most of the existing display boards for mathematical modeling and drawing do not have a writing board, and it is often necessary to write teaching content on another separate writing board, which is not partic...
