Abstract
The utility model provides a magnetic levitation terrestrial globe, which comprises an earth model and a base. The utility model is characterized in that a horizontal internal magnetic ring attached closely to the inner wall is arranged in the middle of the earth model; an external magnetic ring that is not connected with the earth model and is supported by a supporting bracket arranged on the base is arranged correspondingly at the outer side of the earth model; polarities of the internal and the external magnetic rings are arranged in opposite; the centre of the base is provided with a centre stable magnet; a centre iron bar is arranged vertically on a corresponding inner bottom end of the earth model. The utility model has the advantages of novel design, simple structure, convenient operation and flexible rotation.
Description
Affiliated technical field
The utility model relates to the terrestrial globe of teaching appliance, particularly a kind of electromagnetic levitation type terrestrial globe.
Background technology
Known terrestrial globe is to be articulated by its mandrel two ends and semicircular support two ends of being fixed on the base by the earth model of a hollow to constitute.This earth model can rotate with mandrel, is convenient to people and seeks certain country.The terrestrial globe of this traditional structure has lacked feeling of freshness, and the time is dumb once long rotation, and its semicircular support also hinders people's sight in use.
Summary of the invention
The purpose of this utility model is to provide a kind of good looking appearance, novel structure, easy to use and rotate electromagnetic levitation type terrestrial globe flexibly.
Above-mentioned task realizes by this way: this terrestrial globe includes earth model and base, it is characterized in that in the middle of earth model, being provided with a horizontal internal magnet ring of being close to inwall, be provided with one is not connected with earth model and the external magnet ring by the branching bolster supporting on the base in the earth model of the correspondence outside, the opposite up and down setting of polarity of the polarity of internal magnet ring and external magnet ring, also be provided with a center at the base center and stablize magnet, vertically be provided with a center iron staff in the interior bottom of the earth model of correspondence.
From structure of the present utility model as can be known, because the internal magnet ring of earth model is provided with opposite with the external magnet circumpolar on the base, the principle of repelling each other according to the magnetic same sex, earth model must up be promoted by magneticaction, and this moment is because magnet is stablized to the center iron staff generation suction in the earth model in the center on the base, add the deadweight of earth model and center iron staff, its lifting will be restricted, when lifting force and downward acting force reach dynamically steady, this earth model just is in suspended state, can freely rotate and can not break away from easily.This shows that the utility model is very novel, and have simple in structure, easy to use and rotate advantage flexibly.
Description of drawings
Fig. 1 is a schematic appearance of the present utility model.
Fig. 2 is the perspective diagram of the utility model inner structure.
Specific embodiment
As depicted in figs. 1 and 2, earth model 1 two hemispherical shells made of plastic, before two hemispherical shells are involutory with internal magnet ring 2 and center iron staff 3 respectively levels and vertical fixing in earth model 1 housing.At base 4 centers a circular central is set and stablizes magnet 5.The internal diameter of external magnet ring 6 is a bit larger tham the diameter of earth model, and bearing support 7 horizontal fixed by an arc are in base 4 tops.The N utmost point of internal magnet ring 2 up, the S utmost point down, and the N utmost point of external magnet ring 6 is down, the S utmost point up.An end that at last earth model 1 is provided with center iron staff 3 is positioned in the external magnet ring 6 of base 4 tops down just can.Stablize magnet 5 and center iron staff 3 this moment at the mutual expelling force of inside and outside magnet ring (2 and 6) and center mutually under the effect of suction and deadweight, this earth model 1 just is suspended in base 4 tops.
Claims (1)
