Description
Technical field
The utility model is related to a kind of teaching demonstration device, and in particular to physics teaching demonstrator, belongs to physics teaching
Technical field.
Background technology
At present, in physics teaching practice, on textbook, many concepts and law are required for being demonstrated by experiment
And demonstration, so needing in physical teaching course many experiments are done, institute Xue Zhi is more intuitively understood and grasps to meet student
Know.
What laboratory demonstrating resonance was utilized at present is that tuning fork and bead swing, DeGrain, that is to say, that experiment in middle school
Room does not have the instrument of intuitively demonstrating resonance phenomenon up till now, even if some are slightly improved, due to these apparatus structures
Complexity, students are still very puzzled.
Utility model content
The technical problems to be solved in the utility model overcomes existing defect, provides physics teaching demonstrator, by
Eccentric wheel being set on motor, can making vibration to be produced during motor rotation, after vibration is produced, oscillating plate drives spring to do letter
Harmonic motion, when the frequency of simple harmonic motion and the intrinsic frequency of cup identical when, cup will be crushed, and be broken by observing big noggin
Broken different time, then coordinate the frequency size shown on frequency display screen, there just can be one to covibration intuitively
Solution, can be with the problem in effectively solving background technology.
In order to solve above-mentioned technical problem, the utility model provides following technical scheme：
The utility model provides physics teaching demonstrator, including universal wheel, base plate, spring, cup, motor and vibration
Plate, the lower end of the base plate are fixedly connected with universal wheel, and the lower end of the spring is detachably connected with base plate, the spring upper
End is hinged with oscillating plate, and the cup is flexibly connected by rotating suction disc with oscillating plate, is provided with motor in the middle of the oscillating plate,
The motor is fixedly connected with oscillating plate by base, and described motor one end is provided with eccentric wheel and motor is provided with speed governing
Switch, the chassis interior are provided with storage battery and vibration sense device.
Used as a kind of optimal technical scheme of the present utility model, the base plate side is provided with drawer, and described drawer one end sets
There is frequency display screen.
Used as a kind of optimal technical scheme of the present utility model, the universal wheel is provided with brake.
Used as a kind of optimal technical scheme of the present utility model, the cup is provided with 4, and size is all different.
As a kind of optimal technical scheme of the present utility model, the storage battery by microcontroller respectively with frequency display screen
It is electrically connected with vibration sense device.
The beneficial effect reached by the utility model is：By arranging eccentric wheel on motor, turn can motor
Vibration is produced when dynamic, and after vibration is produced, oscillating plate drives spring just do simple harmonic motion, when frequency and the cup of simple harmonic motion
When the intrinsic frequency of son is identical, cup will be crushed, by observing the different time that big noggin is crushed, and frequency display screen
The frequency size of upper display, then two groups of numerals are compared, just there can be one to covibration and get information about.
