Embodiment Construction

[0012] The specific implementation manners of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0013] Depend on Figure 1 to Figure 6 Given, the present invention includes a vertically arranged backboard 1 and a transparent board 2 arranged parallel to the backboard 1, and a moving board 3 arranged in parallel with the backboard 1 is arranged between the backboard 1 and the transparent board 2, and the moving board 3 Simultaneous sliding contact with the backboard 1 and the transparent board 2 constitutes a structure in which the moving board 3 slides between the backboard 1 and the transparent board 2; the moving board 3 has a cylindrical cavity whose axis is perpendicular to the surface of the backboard 1 4. There are a plurality of first piston cavities 5 arranged radially along the axis of the cylindrical cavity 4 and distributed circumferentially on the moving plate 3. The first piston cavities 5 are placed b...

Abstract

The invention relates to a multifunctional mathematical education display board. The multifunctional mathematical education display board comprises a backboard and a transparent plate. A moving plateis arranged between the backboard and the transparent plate. A columnar cavity with the axis being perpendicular to the backboard is formed in the moving plate. A plurality of first piston cavities which are disposed between the transverse plate and the columnar cavity and a plurality of second piston cavities which are disposed between the backboard and the columnar cavity and further communicatewith the columnar cavity are formed in the moving plate. The axis of the first piston cavities is perpendicular to that of the columnar cavity, and the axis of the second piston cavities is parallelto that of the columnar cavity. The first piston cavities and the second piston cavities communicate with each other through double-square-shaped cavity channels. The moving plate is provided with anannular cavity channel penetrating through the multiple double-square-shaped cavity channels. Tension springs and first pistons are arranged in the first piston cavities. A slideable linkage plate isarranged in the columnar cavity. Second pistons are arranged in the second piston cavities and are further connected with the linkage plate. The moving plate is provided with a plurality of sliding grooves, and sliding blocks are arranged in the corresponding sliding grooves. One ends of the sliding blocks are connected with the linkage plate, and the other ends of the sliding blocks make contactwith the backboard. The first piston cavities, the second piston cavities, the double-square-shaped cavity channels and the annular cavity channel are filled with fluid media.

Description

technical field [0001] The invention relates to a mathematical model, in particular to a multifunctional mathematics teaching display board. Background technique [0002] In the field of mathematics teaching, it is usually necessary to draw various curves to express mathematical formulas or functional relationships. Before drawing curves, it is necessary to draw a coordinate system first. For different mathematical formulas or functional relationships, it is often necessary to draw multiple A coordinate system; and for the same curve or graph, it must be drawn repeatedly in different class hours. This drawing method virtually increases the repetitive work of teachers and students and reduces the teaching speed. Contents of the invention [0003] In view of the above situation, in order to make up for the technical deficiencies in the prior art, the present invention provides a multifunctional mathematics teaching display board to solve the problem of repeated drawing of c...
