Therefore, it is badly in need of a kind of super weightless demonstration device.
Utility model content
In order to overcome drawbacks described above, a kind of this new there is provided low cost, good super weightless demonstration device of effect.
To achieve these goals, this new technical scheme is：A kind of super weightless demonstration device, including two core insulators,
Power supply, wire, two light fixtures, spring, metal ball and supports, the core insulator are made up of cup and cup, the cup be with
The hollow cup that cup is communicated, the cup inner surface is provided with one layer of conductive layer, and described two core insulator rims of a cup are symmetrical above and below right
The conductive layer formed after fixing in a cavity and upper and lower cup is connect to be not communicated with；The metal ball is with diameter greater than hollow cup
Internal diameter, the internal diameter of the external diameter less than hollow cup of spring, the metal ball is arranged at the center of cavity, in metal ball top
The heart is fixedly connected with spring one end, and the hollow cup that the spring other end penetrates top core insulator is suspended on support, the lower section
Core insulator bottom be provided with a bracket, bracket is fixedly connected with support；The spring other end is by wire and the pole of power supply one
Connection, the conductive layer of upper cup is connected with another pole of power supply with after a light fixture series connection by wire；The conductive layer of lower cup body with
It is connected by wire with another pole of power supply after the series connection of another light fixture.
Further, the cup inner chamber is parabolic shape.
Further, the core insulator is transparent plastic cup.
Further, the light fixture is the different light fixture of two glow colors.
Further, the light fixture is bulb or light emitting diode.
Originally it is new to have the beneficial effect that：When actual student makes, core insulator can be by cutting two pure water
Bottleneck position makes, low cost, convenient to make, and is favorably improved the manipulative ability of student, and by under super state of weightlessness
The deformation of spring makes different lamps shinny, contributes to the super weightlessness of understanding of student image.
Brief description of the drawings
Fig. 1 is this new super weightless demonstration device structural representation.
Specific embodiment
Technical scheme is clearly and completely described below in conjunction with accompanying drawing, it is clear that described implementation
Example is a part of embodiment of the invention, rather than whole embodiments.Based on the embodiment in the present invention, ordinary skill

In the description of the invention, it is necessary to explanation, term " " center ", " on ", D score, "left", "right", " vertical ",
The orientation or position relationship of the instruction such as " level ", " interior ", " outward " be based on orientation shown in the drawings or position relationship, merely to
Be easy to the description present invention and simplify describe, rather than indicate imply signified device or element must have specific orientation,
With specific azimuth configuration and operation, therefore it is not considered as limiting the invention.Additionally, term " first ", " second ",
" the 3rd " is only used for describing purpose, and it is not intended that indicating or implying relative importance.
In the description of the invention, it is necessary to illustrate, unless otherwise clearly defined and limited, term " installation ", " phase
Company ", " connection " should be interpreted broadly, for example, it may be being fixedly connected, or being detachably connected, or be integrally connected；Can
Being to mechanically connect, or electrically connect；Can be joined directly together, it is also possible to be indirectly connected to by intermediary, Ke Yishi
Two connections of element internal.For the ordinary skill in the art, with concrete condition above-mentioned term can be understood at this
Concrete meaning in invention.
As shown in figure 1, a kind of super weightless demonstration device, including two core insulators 1, power supply 2, two light fixtures 3, springs 4, metal
Ball 5 and support 6, the core insulator 1 are made up of cup 101 and cup 102, and the cup 102 is hollow with what cup 101 was communicated
Cup, the inner surface of the cup 101 is provided with one layer of conductive layer 103, after the docking symmetrical above and below of the rim of a cup of described two core insulators 1 is fixed
The conductive layer 103 formed in a cavity 104 and upper and lower cup 101 is not communicated with；The metal ball 5 is with diameter greater than hollow cup
102 internal diameter, the internal diameter of the external diameter less than hollow cup 102 of spring 4, the metal ball 5 is arranged at the centre bit of cavity 104
Put, the top center of metal ball 5 is fixedly connected with the one end of spring 4, the other end of spring 4 penetrates the hollow cup 102 of top core insulator 1
On the frame 6, the bottom of core insulator 1 of the lower section is provided with a bracket 7, and bracket 7 is fixedly connected with support 6 for suspension；The bullet
The other end of spring 4 is connected by wire with the pole of power supply 2 one, and the conductive layer 103 of upper cup is another with power supply 2 after being connected with a light fixture 3
One pole is connected by wire；The conductive layer 103 of lower cup body is connected with another pole of power supply 2 after being connected with another light fixture 3 by wire
Connect.
In another embodiment of the application, the inner chamber of the cup 101 is parabolic shape.
