Abstract
The utility model relates to a stationary, especially to a novel function coordinatograph, which includes a transverse scale and a longitudinal scale with same length and width; the two scales are intersected at the midpoints; a parabola shaped soft aluminium wire is disposed on the transverse scale; balls made of magnetic material are disposed on the soft aluminium wire; the transverse and the longitudinal scale are both made of iron; the balls are uniformly distributed on the soft aluminium wire; the transverse and the longitudinal scale are both scaled. The coordinatograph of the utility model has a reasonable structure, is used conveniently; can express a required parabola shape easily and visually in function learning process, saves time and labor, reduces the difficulty for teachers and students; and improves the learning efficiency of students.
Description
Technical field
The utility model relates to a kind of schooling apparatus, especially a kind of new type function coordinatograph.
Background technology
In the learning process of function, need mostly to draw the function coordinate diagram by hand, and demonstration all needs the new figure of picture one width of cloth each time, operation very bothers like this, has increased difficulty to the academics and students, has influenced learning efficiency.
The utility model content
The purpose of this utility model is to design new type function coordinatograph a kind of easy and simple to handle in the function learning engineering, time saving and energy saving for overcoming above-mentioned shortcoming.
The technical scheme that the utility model technical solution problem adopts is: a kind of new type function coordinatograph, comprise horizontal scale and vertical scale, described horizontal scale is all identical with length, the width of vertical scale, and intersect at the point midway of two chis, described horizontal scale is provided with the soft aluminium wire of parabolic shape, and described soft aluminium wire is provided with the ball that magnetic material is made.
Described horizontal scale and vertical scale are made by ironwork.
Described ball evenly distributes on soft aluminium wire.
Described horizontal scale and vertical scale are marked with scale.
The beneficial effect that the utility model had is:
The utility model reasonable in design, easy to use, in the function learning process, can easily express required parabola state intuitively, time saving and energy saving, alleviated the difficulty of Faculty and Students, improved student's learning efficiency.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done following detailed description.
As shown in the figure, the utility model comprises horizontal scale 2 and vertical scale 1, the length of described horizontal scale 2 and vertical scale 1, width is all identical, and intersect at the point midway of two chis, described horizontal scale 2 is provided with the soft aluminium wire 3 of parabolic shape, described soft aluminium wire 3 is provided with the ball 4 that magnetic material is made, described ball 4 evenly distributes on soft aluminium wire 3, described horizontal scale 2 and vertical scale 1 are marked with scale 5, during use, the soft aluminium wire 3 of manual adjustments makes it become required parabola state, is adsorbed on the graduated scale of scale anyhow by magnetic ball 4 then to get final product.
