Abstract
The utility model belongs to a model used in science, medical science, and mathematics and especially relates to a resonance phenomenon demonstrating instrument. The demonstrating instrument comprises a pedestal (1) equipped with three slots (2) and four elastic steel sheets (3). One elastic steel sheet (3) is fixedly connected with the pedestal (1) while the other three elastic steel sheets (3) are inserted into the slots (2). Compression screw nuts (4) are disposed on the edges of the slots (2). Transparent containers (5) internally equipped with electronic lamps (6) are disposed on the tops of the elastic steel sheets (3). The resonance phenomenon demonstrating instrument has advantages of a simple structure, convenience, and practicality and is capable of demonstrating a resonance phenomenon visually and vividly.
Description
Technical field
The utility model belongs to the model that science, medical science or mathematics are used, particularly a kind of resonance effect demonstrator.
Background technology
Resonance is a definition on the physics at first, puts most important characteristic and be it with a kind of frequency, i.e. alleged natural frequency swing usually.When being energized when being subjected to extraneous interference, whether its corresponding swaying movement regularity then depends on and disturbs the frequency that shakes desirable consistent with it.The resonance effect that Here it is it has often been said.Single pendulum commonly used comes the demonstrating resonance phenomenon in the teaching, instigates the crossbeam of a plurality of single pendulums, makes certain single pendulum produce resonance, but is not easy to find resonance point in the practice.On January 2nd, 2008, disclosed application number was that 200720122718.3 innovation and creation disclose a kind of resonance apparatus for demonstrating.This device comprises motor, and motor and potentiometer are fixed on the base plate, on the axle of motor rotating disk is housed, and this dish is provided with the coherence piece, is fitted with the many steel wires that natural frequency is different on the base plate, and potentiometer is electrically connected with motor.The weak point of these innovation and creation is: complex structure, and can not demonstrate in the classroom of socket not having.
The utility model content
The purpose of this utility model provides a kind of resonance effect demonstrator simple in structure.
The scheme that the utility model solve the technical problem is: a kind of resonance effect demonstrator, comprise base, 3 slots and 4 elastic steel sheets are set on the described base, 1 elastic steel sheet is fixedlyed connected with base, 3 elastic steel sheets are inserted in the slot, and the edge of slot arranges gland nut.
As further technical scheme, the top of described elastic steel sheet arranges transparent vessel, and velocitron is set in the transparent vessel.
During demonstration, adjust 3 positions of elastic steel sheet in slot, compress elastic steel sheet with gland nut, and make wherein 1 elastic steel sheet expose the length and the equal in length that is fixedly connected on the elastic steel sheet on the base of base.Stir the elastic steel sheet that is fixedly connected on the base, it vibrated back and forth, then in other 3 elastic steel sheets wherein 1 also can and then vibrate, the vibration make the velocitron that is positioned at the elastic steel sheet top shinny, make experiment effect more obvious.
In sum, the utlity model has simple in structure, convenient and practical advantage, can vivid ground demonstrating resonance phenomenon.

Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model base.
Embodiment
As shown in Figure 1 and Figure 2, a kind of resonance effect demonstrator comprises base 1,3 slots 2 and 4 elastic steel sheets 3 are set on the base 1, wherein 1 elastic steel sheet 3 is fixedlyed connected with base 1, and other 3 elastic steel sheets 3 are inserted in the slot 2, and the edge of slot 2 arranges gland nut 4.The top of elastic steel sheet 3 arranges transparent vessel 5, and velocitron 6 is set in the transparent vessel 5.
Claims (2)
1. resonance effect demonstrator, comprise base (1), it is characterized in that: 3 slots (2) and 4 elastic steel sheets (3) are set on the described base (1), 1 elastic steel sheet (3) is fixedlyed connected with base (1), 3 elastic steel sheets (3) are inserted in the slot (2), and the edge of slot (2) arranges gland nut (4).
2. a kind of resonance effect demonstrator as claimed in claim 1, it is characterized in that: the top of described elastic steel sheet (3) arranges transparent vessel (5), and velocitron (6) is set in the transparent vessel (5).
