Embodiment 1

[0033] Embodiment 1, the present invention is a drawing board for computer mathematics teaching, which is mainly used for drawing during teaching, which is convenient for drawing, and the drawing size is accurate, making it easier for students to understand when learning, including a drawing board 1 for use in drawing, On the rear side of the drawing board 1 there is a cloth roll slot 2, and the roll cloth 4 is accommodated in the cloth roll slot 2, and the roll cloth 4 is wound on the winding device 3, so that the roll cloth 4 can be stretched and self-reset on the winding device 4 , There are many types of structures for the winding device 3. In this embodiment, a rotating shaft can be installed in the cloth rolling groove 2, and the cloth roll 4 is wound on the rotating shaft. Realize the rotation, and rely on the coil spring to realize automatic reset, or choose a structure similar to the luggage rack structure in the middle of the trunk in the existing car, or choose a str...

Embodiment 2

[0039] Embodiment 2, on the basis of Embodiment 1, the first gear 18 is also provided with a scale 37, the scale 37 is provided with a second scale 38, and the material at the second scale 38 is also a transparent material, which is convenient for observation. 37 is provided with a through hole 39, and the sleeve 21 on the upper end of the second gear 19 is placed in the through hole 39. When the first gear 18 and the second gear 19 are moved, the scale 37 moves together with the first gear 18, and the second gear 18 moves together. The gear 19 moves in the through hole 39 , and the scale 37 does not follow it. The sleeve 21 on the upper end of the second gear 19 is fixedly sleeved with a second pointer 40 always pointing to the second scale 38 .

Embodiment 3

[0040] Embodiment 3, on the basis of Embodiment 1, a bearing seat is fixed at the junction of the double-ended screw 29 and the rectangular frame 26 , so that the double-ended screw 29 can be rotated but cannot be moved. The purpose is to fix the double-ended screw 29 .

Abstract

The invention relates to a drawing board for computer mathematics teaching. The problem that standard drawing cannot be conducted in the drawing process of existing mathematics teaching is effectivelysolved. According to the technical scheme, the drawing board for computer mathematics teaching comprises a drawing board body. A rolled cloth groove is fixed to the rear side of the drawing board body, and a winding device is installed in the rolled cloth groove. Rolled cloth is wound onto the winding device, and the middle of the end of the rolled cloth is connected with a rigid rope. A pulley block is fixed to the drawing board body. The rigid rope is connected with a ruler. A locking device is fixedly installed at the position of the pulley block. First magnetic blocks are installed on therear side face of the ruler. The ruler comprises a shell, and the shell is provided with a guide rail. First scales are engraved on the ruler. A rack is installed inside the ruler, and a first gear and a second gear are engaged with the rack. First rotating shafts penetrate through the inside of the first gear and the inside of the second gear correspondingly. The upper end and the lower end of each first rotating shaft are both sleeved with sleeves. The lower ends of the sleeves are connected with corresponding sliding blocks, and the sleeves are fixedly sleeved with first pointers. Third magnetic blocks are installed in corresponding positioning grooves. By means of the drawing board for computer mathematics teaching, teaching drawing can be facilitated, and drawing is standard.

Description

technical field [0001] The invention relates to the technical field of computer mathematics teaching, in particular to a drawing board for computer mathematics teaching in teaching. Background technique [0002] Computer mathematics is a subject in universities. In university mathematics teaching, in order to enable students to intuitively understand the meaning of mathematical formulas, teachers often draw mathematical formulas on the blackboard. In the existing university teaching drawing, teachers use hand-painted Freehand drawing in the form of drawing, in the process of drawing, often the drawing size is not standard, there is no drawing coordinate system, the drawing line is curved, when drawing a circle, the radius size on the ruler is accurate, but it is often drawn out The radius of the circle is different from the actual radius. It is often either too large or too small, and a complete and regular circle cannot be drawn, so that the drawn graphics do not match the ...
