Embodiment 1

[0037] Embodiment 1. The present invention is a dynamic display device for mathematical models, including a base 1, which can be placed on a desk for use, and a display board 2 is fixedly installed on the top of the base 1. When in use, the display board 2 The front side of the display board 2 faces the students, and the front side of the display board 2 is provided with a grid slot 3 composed of a plurality of horizontal slots 01 and vertical slots 02. The grid slot 3 is the coordinate system grid, and the final grid slot 3 is the origin position, the front side of the display board 2 is provided with a square ring groove 4 outside the grid groove 3, the four corners of the square ring groove 4 are rounded, and the inside of the square ring groove 4 Sliding left and right are installed with two wire barrels 5 below the grid groove 3. The two wire barrels 5 can slide in the square ring groove 4 to make a circular motion. The two wire barrels 5 are connected with an asymptote 6,...

Embodiment 2

[0040] Embodiment 2, on the basis of Embodiment 1, the bottom of each wire barrel 5 and wire post 7 is rotatably connected with a bottom plate 16, and each wire barrel 5 and line post 7 can rotate on the corresponding bottom plate 16 , when the wire barrel 5 and the wire post 7 move in the square ring groove 4 respectively, the asymptote 6 can drive the wire barrel 5 and the wire post 7 to rotate, so that the axis of the asymptote 6 can always run through the wire barrel 5 and the wire post 7, the two sides of the bottom of each base plate 16 are rotatably equipped with wire spool sheaves 17 in the square ring groove 4, and the bottom plate 16 can slide in the square ring groove 4 through two wire spool sheaves 17, And can slide from the top or the bottom of the square ring groove 4 to the left end or the right end of the square chute 4, so that the asymptote 6 can be simulated at any position on the front side of the display board 2. The inside of the chute 4 is provided with...

Embodiment 3

[0041] Embodiment three, on the basis of embodiment two, each positioning rod 19 is rotatably installed with a bobbin 22 located in the bobbin 5, the bobbin 22 can rotate on the positioning rod 19, and the positioning rod 19 can rotate on the bobbin 22 The middle part moves axially, each of the bobbins 16 and the bobbins 5 are respectively connected with torsion springs 23. When the bobbins 16 rotate, the torsion springs start to store force, and the two asymptotes 6 respectively run through the corresponding bobbins 5. The outer wall is wound on one of the spools 22, and the asymptote 6 on the spool 22 can be pulled and released when the distance between the bobbin 5 and the post 7 becomes larger.

Abstract

The invention provides a mathematical model dynamic display device, and solves the problems of an asymptotic line of an existing curve during teaching. The asymptotic line is simulated through the flexible neon line which is connected between the bobbin and the line column and penetrates through the original point, and the line column can be driven to move synchronously through the linkage line by moving the bobbin in the square ring groove in the display board, so that the angle of the asymptotic line is changed. During teaching, asymptotes expressing different equations can be rapidly presented on the display board at any time. The multiple telescopic rods move the positions of the multiple coordinate sliding blocks, so that the curve radian between the multiple curve rings changes, due to the fact that the curve is the flexible neon line, the flexible neon line between every two curve rings is an arc line when the flexible neon line is bent, the flexible neon line can present a complete curve, and the flexibility of the flexible neon line is improved. During teaching, different curves can be rapidly presented on the display board at any time according to different equations, manual drawing of curve asymptotes can be replaced, class time is saved, and teaching efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of teaching tools, in particular to a dynamic display device for mathematical models. Background technique [0002] Asymptote means: when a point M on the curve is infinitely far away from the origin or infinitely close to the discontinuity point along the curve, if the distance from M to a straight line approaches zero infinitely, then this straight line is called the asymptote of the curve; [0003] In the current mathematics teaching process, teachers draw asymptotes and curves on the blackboard, or teach through multimedia production. When drawing manually, it is necessary to determine the positions of multiple coordinate points on the curve, and then draw multiple The part of the curve between coordinate points to get the complete curve. [0004] However, when teachers manually connect the curve parts between multiple coordinate points, they often cannot effectively connect multiple coordinate points w...
