The utility model also comprises a magnetic particle display board which can display the vibration trace of the simple harmonic oscillator, the support bracket is also provided with a guide way which is vertical to the vibration direction of the simple harmonic oscillator. The display board is arranged on the support bracket via the sliding of the guide way and is parallel to the vibration direction plane surface of the simple harmonic oscillator, and the support bracket is also provided with a driving device which can display the sliding trace of the board along the guide way. The utility model can clearly record the simple harmonic vibration trace of the spring and is convenient for the observing and studying the simple harmonic vibration of the spring.
Description
Technical field
The utility model relates to a kind of teaching instrument and equipment, especially a kind of spring simple harmonic oscillation demonstrator commonly used in physics teaching.
Background technology
In physics teaching, experiment is a kind of very effective course of exploitation students'ability for practice and elaborative faculty, he can improve the interest of students study greatly and excavate the potentiality of further studying intensively, and wherein, the spring simple harmonic oscillation is exactly such experiment topic.But the experimental apparatus of the spring simple harmonic oscillation in teaching at present on the classroom is very simple and crude but, be generally and adopt oscillator under the effect of spring, to do simple harmonic oscillation, and everybody adopts the way with the eye Direct observation, though this kind method and instrument are effectively directly perceived, but but can not note spring really and make the whole process of simple harmonic oscillation and the attenuation process of simple harmonic oscillation, this is to further understanding and research very the inconvenience of classmates to the simple harmonic oscillation of spring.
Summary of the invention
The technical problems to be solved in the utility model has provided a kind ofly can know that the record spring makes the spring simple harmonic oscillation demonstrator that the track of simple harmonic oscillation is observed and learnt to make things convenient for classmates.
For solving the problems of the technologies described above, the technical solution of the utility model is: spring simple harmonic oscillation demonstrator, comprise support, and be arranged on the simple harmonic oscillator of an end of support upper spring, described simple harmonic oscillator is a magnetic oscillator; Described simple harmonic oscillation demonstrator also comprises the magnetic display board that can show the simple harmonic oscillator oscillation trajectory, also be provided with the guide rail vertical on the described support with the simple harmonic oscillator direction of vibration, described display board also is provided with on the described support and can makes the drive unit of display board along the guide rail slip by being arranged on the support on the plane parallel with the simple harmonic oscillator direction of vibration that guide rail slides.
As a kind of optimal way, described drive unit is for being provided with rotating leading screw and propulsion system on support, described display board is provided with corresponding screw, and the match driving that is incorporated in propulsion system of the screw on described leading screw and the display board drives down display board and slides along guide rail.
As another kind of optimal way, the bottom of described support is provided with the adjustment bolt.
Adopt the spring simple harmonic oscillation demonstrator of said structure, owing to adopted oscillator and the magnetic display board that has magnetic, driving the magnetic display board by passive device slides along the direction vertical with oscillator vibration, by the magnetic effect in oscillator and the magnetic display board, so just can be complete note the whole process that spring is done simple harmonic oscillation, provide good help for the academics and students further is familiar with the spring simple harmonic oscillation.Adopt simple screw type transmission magnetic display board, both can simplified structure, promoted the stability and the homogeneity of the slip of magnetic display board again, the adjustment bolt of frame bottom can be adjusted the level of this simple harmonic oscillation demonstrator easily, so that this demonstrator is more accurate.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is further described:
Fig. 1 is the front elevation of spring simple harmonic oscillation demonstrator of the present utility model;
Fig. 2 is the left view of spring simple harmonic oscillation demonstrator of the present utility model.
Embodiment
See figures.1.and.2, a kind of spring simple harmonic oscillation demonstrator of the present utility model is, comprise that the bottom has the support 1 of four legs, the level of this simple harmonic oscillation demonstrator of adjustment for convenience is so that this demonstrator is more accurate, can be provided with the adjustment bolt in the bottom of support 1, or directly will adjust bolt and be arranged on four legs; One end of the spring that is provided with on support 1 is provided with simple harmonic oscillator 7, and this simple harmonic oscillator 7 is a magnetic oscillator; And this simple harmonic oscillation demonstrator also comprises the magnetic display board 2 that can show simple harmonic oscillator 7 oscillation trajectories, magnetic display board 2 can adopt magnetic blackboard common on the market: promptly be filled with the magnetic that has magnetic in the cellular grid that fuses, cover at the film of grid external side of main body by layer of transparent, when the object that has magnetic near the process panel of magnetic display board, magnetic can be adsorbed on the transparent membrane.On support 1, also be provided with the guide rail 3 vertical with simple harmonic oscillator 7 direction of vibration, magnetic display board 2 is slidingly matched with guide rail 3 and is arranged on the support 1 on the plane parallel with simple harmonic oscillator 7 direction of vibration and certain at interval each other distance, on support 1, also be provided with the drive unit that display board 2 is slided along guide rail 3, this drive unit is for being provided with rotating leading screw 4 and propulsion system 5 on support 1, and on display board 2, be provided with and leading screw 4 corresponding screws, the match driving that is incorporated in propulsion system 5 of leading screw 4 and screw on the display board 2 drives display board 2 down and reciprocatingly slides along guide rail 3.Because this spring simple harmonic oscillation demonstrator is a physical experiment apparatus, do not need great power, so the wheel box that the wheel box that these propulsion system 5 can adopt little variable-frequency motor to drive also can adopt little direct current generator to drive is realized the driving to leading screw 4.
Spring simple harmonic oscillation demonstrator of the present utility model has adopted simple structure to solve the problem that the student can not note the simple harmonic oscillation of spring fully when doing the spring simple harmonic oscillation, made things convenient for the research of student, strengthened further understanding simple harmonic oscillation to simple harmonic oscillation.And if change the spring in the utility model into rope, and with the below that is arranged on oscillator of magnetic display board level, and, then can realize complete documentation to the simple harmonic oscillation track of rope pendulum at the uniform velocity to slide on the direction vertical with the oscillator swaying direction.
