[0026] like Figures 1 to 5As shown, a multifunctional teaching aid based on mathematical function curve modeling comprises: a base 1, the base 1 is arranged in an I-shape, fixed frames 2 are fixedly installed on both sides of the base 1, and positioning columns 3 are arranged in the middle of the two fixed frames 2 to connect them, and fixed plates 5 are arranged at the four corners of the bottom end of the base 1; a teaching aid body 6, which is rotatably installed between the two fixed frames 2 and is used to demonstrate function teaching; a plurality of demonstration blocks 8, which are evenly distributed on one side of the teaching aid body 6, and the plurality of demonstration blocks 8 are arranged in a chessboard-like distribution, and are used to cooperate with the teaching aid body 6 to demonstrate function teaching, and a circular groove 9 is provided inside the demonstration block 8, and a demonstration column 13 is slidably installed inside the circular groove 9, wherein the tops of the two fixed frames 2 are arranged in a semicircular arc shape, and the middle parts of the tops of the fixed frames 2 are provided with threaded holes 4, and the middle parts of both sides of the teaching aid body 6 are provided with threaded grooves adapted to the threaded holes 4, and limiting bolts 7 are arranged between the threaded holes 4 and the threaded grooves for locking. When the teaching aid is used for teaching, After the teaching aid is placed in the designated position, the limit bolt 7 is then screwed for adjustment, and then the teaching aid body 6 is rotated between the fixed frame 2 to adjust the demonstration angle of the teaching aid body 6. The teacher can easily adjust the angle of the teaching aid body 6 to better demonstrate the different characteristics of the function curve. When using the teaching aid for teaching, each step of the function demonstration will be demonstrated step by step through a number of demonstration blocks 8 on the teaching aid body 6, and the several demonstration blocks 8 distributed in a chessboard shape can make the teaching demonstration more regular, so that the viewer can see it at a glance, making the demonstration more regular and orderly, and the viewer can clearly see the demonstration process of each step, which is helpful for understanding and memory. When the demonstration block 8 is demonstrating, the demonstration column 13 inside the demonstration block 8 is adjusted to display in different positions to achieve different demonstration effects. It can be cross-displayed in a state with multiple sections of different function curves, and it can be adjusted at will when the staggered positions of multiple different function curves are changed, so as to achieve good teaching effects.
[0027] like Figures 3 to 5As shown, a slide groove 10 is provided on one side of the inner part of the circular groove 9, a slide rod 15 is rotatably installed on one side of the demonstration column 13, and the slide rod 15 is slidably installed in the inner part of the slide groove 10. Three first guide blocks 11 used in conjunction with the slide rod 15 are also arranged equidistantly in the inner part of the slide groove 10. A reset spring 14 is fixedly connected to one end of the demonstration column 13 close to the inner part of the circular groove 9, and the other end of the reset spring 14 is connected to the inner bottom surface of the circular groove 9. The demonstration column 13 is arranged in multiple layers with different diameters, and the slide rod 15 is arranged in an "L" shape. A torsion spring is arranged at the connection between the slide rod 15 and the demonstration column 13. The initial surface is inclined, one side of the first guide block 11 is also inclined, and the other side is set in an inward concave arc shape. The side of the slide 10 close to the bottom surface of the circular groove 9 is provided with a second guide block 12 adapted to the inward concave arc surface of the first guide block 11. In the demonstration process of the function curve, the walking of the matching curve is adjusted on different demonstration blocks 8. At this time, the demonstration column 13 at the position of the next step curve is pressed to drive the extrusion reset spring 14 to drive the slide bar 15 to slide inside the slide 10. In the sliding process, the slide bar 15 will first drive the slide bar 15 to rotate a certain amount through the inclination of the initial position of the slide 10. The slide bar 15 is connected to the demonstration column 13 by a torsion spring. When the demonstration column 13 is pushed inward for a first distance, during the travel of this distance, the slide bar 15 is driven by the initial inclined position of the slide groove 10 and the inclined surface of the first first guide block 11 to slide between the first guide block 11 and the slide groove 10, and then reaches between the two first guide blocks 11. At this time, under the action of the torsion spring, the slide bar 15 is driven to rotate and reset, and after resetting, the slide bar 15 is fixed to the concave arc surface on the other side of the first guide block 11 under the action of the reset spring 14, thereby making the demonstration column 13 push inward for a first distance. The demonstration column 13 moves inward for a distance, and a plurality of first guide blocks 11 are arranged inside, so that in coordinated use, multiple different position changes of the demonstration column 13 are achieved. When the slide bar 15 reaches the position of the last first guide block 11, the demonstration column 13 is pressed again, and is reset through the guidance of the second guide block 12. Under the action of the reset spring 14, the demonstration column 13 is directly reset to the initial state for use. In this way, the demonstration column 13 can reach different exposed states, and can be used in conjunction with its multi-layer structure with different diameters to achieve the effect of different function curves in coordination with the demonstration.
[0028] like Figure 3 As shown, one side of the demonstration column 13 away from the circular groove 9 is set to a magnetic material. This end is a magnetic material and can be used in conjunction with external magnetic demonstration chess pieces for demonstration to achieve a better demonstration effect.
