Abstract
The utility model discloses a teaching aid for generating curved surface models which overcomes a problem that when a teacher is demonstrating a curved surface and an equation thereof, a corresponding three-dimensional model is absent, so that students cannot understand knowledge of the curved surface in space directly. The utility model is a teaching aid which can generate various curved surfaces at will. A plane coordinate scale plate and a height coordinate scale plate are placed in parallel, wherein the plane coordinate scale plate is over the height coordinate scale plate, and the plane coordinate scale plate and the height coordinate scale plate are fixed and supported by corner columns. Height adjusting rods pass through the plane coordinate scale plate and the height coordinate scale plate. Snap columns are arranged on the height adjusting rods and snap slots corresponding to the snap columns are positioned on the height coordinator scale plate. When the directions of the snap columns and the snap slots are the same, the height adjusting rods can be pushed to adjust height. The heights of the height adjusting rods can be fixed by rotating the height adjusting rods to stagger the snap columns and the snap slots. The teaching aid for generating a curved surface model is applicable to the teaching process of advanced mathematics.
Description
Technical field
The utility model relates to a kind of surface model and generates teaching aid, and the surface model that is specifically related to a kind of higher mathematics special use generates teaching aid, belongs to the teaching aid field.
Background technology
In how much of the space analysis that higher mathematics is said, a lot of concepts are very abstract, and the curvature portion in the higher mathematics especially simple explained the student by the teacher and is difficult to understanding.In the course of time, will make the student lose the interest of study, influence study schedule.
The utility model content
The purpose of this utility model is in order to solve present teacher in the explanation to curved surface and equation thereof, there is not corresponding stereoscopic model, the problem that the student can't be familiar with the curved surface in the space intuitively provides a kind of teaching aid that can generate various surface models arbitrarily.
The technical solution of the utility model is: a kind of surface model generates teaching aid, comprises planimetric coordinates scaleplate and height coordinate location-plate, and described planimetric coordinates scaleplate and height coordinate location-plate be arranged in parallel up and down, carry out fixed support by corner post; Height regulating rod passes planimetric coordinates scaleplate and height coordinate location-plate, has equally spaced several card posts on the height regulating rod, has on the height coordinate location-plate and blocks the corresponding draw-in groove of post.
To have with the designated length be the plane coordinate system of unit in portrayal on the described planimetric coordinates scaleplate, and the position that height regulating rod passes the planimetric coordinates scaleplate is the intersection point that coordinate system is reached the standard grade.
The spacing of the card post that has on the described height regulating rod is the integral multiple of plane coordinate system unit length on the planimetric coordinates scaleplate or can be divided exactly by unit length.
The utility model compared with prior art has following effect: 1. surface model of the present utility model generates teaching aid, by adjusting the lock height of height regulating rod, can generate the curved surface of arbitrary shape.2. after the height regulating rod adjustment finishes, can show the curved surface effect by on height regulating rod, laying cloth, make understanding more directly perceived.In addition, this surface model generates the simple in structure, easy to use of teaching aid.
Description of drawings
Fig. 1 is the structure key diagram of the utility model product.
Fig. 2 is the design sketch after the utility model product generates curved surface.
Fig. 3 is the partial enlarged drawing of the utility model product.
Embodiment
Embodiment one: present embodiment is described in conjunction with Fig. 1 ~ Fig. 3, a kind of surface model generates teaching aid, comprise planimetric coordinates scaleplate 2 and height coordinate location-plate 4, described planimetric coordinates scaleplate and height coordinate location-plate be arranged in parallel up and down, carry out fixed support by corner post 1; Height regulating rod 3 passes planimetric coordinates scaleplate 2 and height coordinate location-plate 4, has equally spaced several cards post 3-1 on the height regulating rod 3, has on the height coordinate location-plate 4 and blocks the corresponding draw-in groove 4-1 of post 3-1.
In this embodiment, to have with the designated length be the plane coordinate system of unit in portrayal on the planimetric coordinates scaleplate 2, and the position that height regulating rod 3 passes planimetric coordinates scaleplate 2 is the intersection point that coordinate system is reached the standard grade.
Embodiment two: this embodiment is with the difference of embodiment one: the spacing of the card post 3-1 that has on the height regulating rod 3 is the integral multiple of plane coordinate system unit length on the planimetric coordinates scaleplate 2 or can be divided exactly by unit length.
Principle of work:
Behind the known surface model and function thereof that will generate, in function, choose a series of point, namely choose the D coordinates value (x of a series of point on the curved surface, y, z), as point (x1, y1, z1), find out in the plane coordinate system of planimetric coordinates scaleplate 2 portrayal that (x1 y1), rotates the height regulating rod 3 of this position, after making card post 3-1 and draw-in groove 4-1 direction being consistent, promote height regulating rod 3 until reaching the z1 value.Rotate height regulating rod 3 again, make card post 3-1 and the draw-in groove 4-1 angle that staggers, rotation height regulating rod 3 is locked at this height.The summit that rotates height regulating rod 3 this moment namely be point (x1, y1, z1).Find out other points of choosing successively, namely finish the generation of surface model.For being that visual effect is more directly perceived, can on height regulating rod, laying cloth and show curved surface.
When this teaching aid when not using, the rotation height regulating rod 3, make card post 3-1 consistent with draw-in groove 4-1 direction, the promotion height regulating rod 3 make it to fall, make the plug 5 of height regulating rod 3 heads be stuck on the planimetric coordinates scaleplate 2.
