Abstract
The utility model is related to a kind of teaching sine and cosine Image Rendering pen, and it includes crank, fixed pole and rocking arm；The crank is provided with fixed pole, and the openend of the rocking arm is machined with U-lag, and the fixed pole constitutes chute and is connected with the U-lag of rocking arm so that fixed pole can be moved back and forth in U-lag；The rocking arm is fixed with drawing pen away from one end of fixed pole；The rocking arm lower section is provided with white board, and two rollers are provided with the two ends of white board.Can be used to the sine and cosine image for helping secondary school teachers that different cycles, frequency and amplitude are drawn on classroom.
Description
Technical field
The utility model is related to a kind of teaching plotting unit, more particularly to a kind of teaching sine and cosine Image Rendering pen.
Background technology
Teacher is when classroom instruction is carried out, it will usually teach knowwhy by the method for drawing schematic diagram, and current
Draw most of using freehand on classroom, compare the waste class period；Certainly, since the popularization of multimedia teaching,
Classroom efficiency obtains larger raising, but the learning initiative of student is but substantially reduced, and student can not really understand signal
How figure draws, and gradually lacks study enjoyment, so that passive study.
Utility model content
The purpose of this utility model is, there is provided one kind teaching sine and cosine Image Rendering pen, can be used to help middle school
Teacher draws the sine and cosine image of different cycles, frequency and amplitude on classroom.
In order to solve the above-mentioned technical problem, the utility model proposes following technical scheme：Sine and cosine image is used in one kind teaching
Pen is drawn, it includes crank, fixed pole and rocking arm；The crank is provided with fixed pole, and the openend of the rocking arm is machined with U-lag,
The fixed pole constitutes chute and is connected with the U-lag of rocking arm so that fixed pole can be moved back and forth in U-lag；The rocking arm is remote
One end from fixed pole is fixed with drawing pen；The rocking arm lower section is provided with white board, and two rollers are provided with the two ends of white board.
The crank uses electric-controlled type or hand-rail type, drives it to rotate；The rotating speed of the crank can be adjusted.
The crank is rotated while driving fixed pole to rotate one week, and fixed pole is in the U-lag on rocking arm just past one
Single direction stroke, rocking arm forms a sin cos functionses figure away from one section of fixed drawing pen up and down motion a cycle of fixed pole
Picture.
Blank sheet of paper is placed with the white board, roller is connected with motor output shaft, drives white board uniform rectilinear's fortune backward
It is dynamic.
Change the frequency or the speed moved backward of roller of crank circular motion, you can draw out various different frequencies,
The sin cos functionses image of different cycles or different amplitudes.
The utility model has the advantages that：
Teaching uses simple operation, and simple structure changes the speed that the frequency or roller of crank circular motion are moved backward
Degree, can draw out the sin cos functionses image of various different frequencies, different cycles or different amplitudes, and practicality is high.
Brief description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and examples.
Fig. 1 is overall structure diagram of the present utility model.
In figure：Crank 1, fixed pole 2, rocking arm 3, white board 4, roller 5.
Specific embodiment
Implementation method of the present utility model is described further below in conjunction with the accompanying drawings.
Such as Fig. 1, one kind teaching sine and cosine Image Rendering pen, it includes crank 1, fixed pole 2 and rocking arm 3；On the crank 1
Fixed pole 2 is provided with, the openend of the rocking arm 3 is machined with U-lag, and the fixed pole 2 constitutes chute and coordinates company with the U-lag of rocking arm 3
Connect so that fixed pole 2 can be moved back and forth in U-lag；The rocking arm 3 is fixed with drawing pen away from one end of fixed pole 2；The rocking arm
3 lower sections are provided with white board 4, and two rollers 5 are provided with the two ends of white board 4.
Further, the crank 1 uses electric-controlled type or hand-rail type, drives it to rotate；The rotating speed of the crank 1 can
Regulation.Using said structure can regulation motor rotating speed come control crank rotate rotating speed and blank sheet of paper move speed.
Further, while the crank 1 is rotated and drives fixed pole 2 to rotate one week, fixed pole 2 is in the U-lag on rocking arm 3
Just past a single direction stroke, rocking arm 3 forms one away from one section of fixed drawing pen up and down motion a cycle of fixed pole 2
Bar sin cos functionses image.
Further, blank sheet of paper is placed with the white board 4, roller 5 is connected with motor output shaft, drive white board 4 to
Linear uniform motion afterwards.Being moved up and down by the periodicity of linear uniform motion and rocking arm 3, it is different easily to draw out
Sin cos functionses image.
Further, the speed that the frequency or roller 5 of the circular motion of crank 1 are moved backward is changed, you can draw out each
Plant the sin cos functionses image of different frequency, different cycles or different amplitudes.
The course of work of the present utility model and operation principle are：
When need draw sin cos functionses image when, cranking lever 1 by crank 1 drive fixed pole 2, by fixed pole 2 with shake
U-lag on arm 3 is slidably matched, and then band motion rocker arm 3 is moved, and the drawing pen installed in the other end of rocking arm 3 will be in white board 4
Top moves back and forth, while roller 5 drives white board 4 to do linear uniform motion, now drawing pen can just be drawn on blank sheet of paper
Go out sin cos functionses image.
Change the speed that the frequency or roller 5 of the circular motion of crank 1 are moved backward, you can draw out various different frequencies
The sin cos functionses image of rate, different cycles or different amplitudes.
By above-mentioned description, those skilled in the art completely can be without departing from this utility model technological thought
In the range of, carry out various changes and amendments all within protection domain of the present utility model.It is of the present utility model not most
Matters, belong to the common knowledge of those skilled in the art.
