Description
Technical field
The utility model relates to a kind of teaching experiment instrument, exactly is a kind of spring oscillator simple harmonic oscillation experiment instrument.
Background technology
In the senior middle school physics teaching, the spring oscillator simple harmonic oscillation is an emphasis and difficult point, and spring oscillator simple harmonic oscillation experiment is to the decisive role of setting up of spring oscillator simple harmonic oscillation notion.The experiment way of being told about in the current teaching materials is: allow spring oscillator vibrate, test the teacher simultaneously and rotate crank and promote the recording chart precession, the recording pointer vibration figure line that then draws on paper.The experiment of telling about in the teaching material is a kind of Utopian education experiment model, in fact there is no the existence of this equipment on the market and in the field research.
The utility model content
The purpose of this utility model is for providing a kind of exercisable experimental apparatus in the teaching, the experiment instrument of doing spring oscillator simple harmonic oscillation experiment in the senior middle school physics teaching a kind of reasonable in design, simple in structure, easy to operate being provided to people.
A. described paper-advance unit comprises the motor in paper feed axle, paper feed bearing and the wheel box, and paper feed axle one end is connected with motor, and the other end is equipped with a bearing, be furnished with on the paper feed axle a pair of and be fixed in that a pair of paper feed bearing on the base is complementary drive the paper rubber tire;
B. described spring oscillator device comprises air track, spring, bob and air pump, spring one end is fixed on the pole of air track left end, the other end is connected with slide block on the air track, bob is fixed on the slide block, recording pointer is rotated with in the bob bottom, places the air pump in the wheel box to be connected with air track on being fixed in base by tracheae.
In addition, the enterprising reel of base holds the rear portion and is fixed with " U " type and leads the paper rail, also is fixed with the platen card on the base.
One press-contacting type switch and power supply indication LED are housed on the wheel box, are connected with motor, power supply by lead.
During use, energized is sent into recording chart to drive in the middle of rubber tire and the paper feed bearing by being led the paper rail after the power supply indication LED is bright, is compressed by the platen card.The experiment beginning, slide block is placed the left end of air track, booster air pump, slide block is blown afloat by air-flow, lose friction force, under the restoring force effect of spring, begin vibration, press the press-contacting type switch simultaneously, it is logical to make it be when urging state motor circuit, motor rotates, and drives the paper feed axle and rotates, and it is out-of-date that recording chart is walked between paper rubber tire and paper feed bearing by driving on the paper feed axle, sine line when the recording pointer under the spring oscillator ball will be drawn spring oscillator and do simple harmonic oscillation on recording chart is promptly finished spring oscillator simple harmonic oscillation experiment.
The utility model effect
The utility model provides a kind of experiment instrument of doing spring oscillator simple harmonic oscillation experiment not only for the teacher in physics teaching, and this experiment instrument is reasonable in design, and is simple in structure, easy to operate, with low cost.
