Abstract
The utility model aims to solve the difficulty with how to simulate the sunlight-formed day/night state in real time and on real site and provides a shaftless terrestrial globe capable of displaying time, days and nights, and the shaftless terrestrial globe is used for learning the day/night conditions of various regions. The utility model is realized through measures as follows: the day-and-nightshaftless terrestrial globe mainly comprises a base, a bracket, a day-and-night ball and a geographical pattern ball; the bracket is mounted on the base, the geographical pattern ball is mounted in the day-and-night ball through a rolling ball and can be rotated in the day-and-night ball in each direction; the day-and-night ball is mounted on the base and can be rotated vertically around the base. With a simple structure, the magnetic-repulsion time-and-day/night display terrestrial glob solves the problem that an ordinary terrestrial globe has difficulty in displaying the day/night states ofthe earth, the operation is convenient, the teaching function of the terrestrial globe is developed, and people can easily grasp the knowledge about how the days and nights of the earth are formed, therefore, the utility model is a teaching and interior-decoration terrestrial globe which is more multifunctional and scientific.
Description
Technical field
The utility model relates to a kind of terrestrial globe, particularly relates to a kind of terrestrial globe of Shaftless day and night.
Background technology
Terrestrial globe is the instrument that shows earth geography situation, various countries and regional position distribution, often uses in teaching, scientific research, particularly the instruments used for education that must use in the teaching of middle and primary schools' Science Curriculum.Existing terrestrial globe is all fairly simple, and it comprises central rotating shaft fixing on base, support and the support, can simulate the spheroid of earth rotation on the central rotating shaft, by the geographic distribution drafting each countries and regions is arranged on the spheroid.Yet the earth is also done the revolution of 1 year one-period around the sun, and this has just formed spring, summer, autumn and winter that we experience year after year and the sunrise sunset of every day.Present terrestrial globe can reflect the rotation of the earth, but can not reflect earth rotation on the terrestrial globe time, owing to and the sun between the The diurnal distribution situation that forms of relation, be difficult for making the student to understand the earth and form the state that changes round the clock.Attempt to want on terrestrial globe, to embody the terrestrial globe of state round the clock and also have at present, yet all realize that by the interior mode such as light source of establishing effect is unsatisfactory.
The utility model content
The utility model provides a kind of demonstration time of shaftless and terrestrial globe round the clock for the state round the clock that solves in real time, simulated solar illumination on the spot forms the earth, is used to understand the situation round the clock of various places.
The utility model is realized by following measure: the terrestrial globe of this Shaftless day and night mainly comprises base, support, ball, geographical pattern ball round the clock; Support is installed on the base, and geographical pattern ball is installed in round the clock in the ball by ball, can rotate in all directions in the ball round the clock; Ball is installed on the base round the clock, can rotate around the base vertical axis.
In the described geographical pattern ball magnet or magnetizable object are housed.
Described ball round the clock is marked with one day time scale.
The utility model has solved the state issues round the clock that common terrestrial globe is difficult for representing the earth with easy method, simple in structure, easy to operate, enlarged the instructional function of terrestrial globe, being easy to people and grasping the knowledge that the earth forms round the clock, is teaching and the interior decoration terrestrial globe that a kind of function is comprehensive more, have more scientific meaning.
Description of drawings
Fig. 1 is a schematic appearance of the present utility model.
Fig. 2 is a structural representation of the present utility model.
Fig. 3 is the synoptic diagram of spherical structure round the clock of the present utility model.
Fig. 4 is the utility model ball rotating shaft round the clock synoptic diagram.
Fig. 5 is the utility model base synoptic diagram.
Number in the figure is: base 1, and support corresponding interface 11, corresponding mouthful 12 of ball rotating shaft round the clock, ball 2 round the clock, ball rotating shaft round the clock 21, time scale 22, geographical pattern ball 3, earth's axis positioning magnet 31,32 drives magnet 33, support 4, stent magnet 41,42, outer magnet 5, ball 6.
Embodiment
Below in conjunction with example and accompanying drawing the utility model is described further:
As shown in Figure 1, be the utility model device appearance synoptic diagram, the hemisphere shown in the dotted line illustrates the geographical object of its interior part to be in dim light of night state, second half geographical object place state on daytime for the gloomy transparent body or other color dyes part.
As Fig. 2, Fig. 3, Fig. 4, shown in Figure 5, geographical pattern ball 3 is installed in round the clock in the ball 2 by several balls 6, ball 6 is selected number of elements as required, at least six, be evenly distributed on geographical pattern ball 3 and round the clock between the ball 2, for preventing that ball from walking, on geographical pattern ball 3, place the position of ball and establish suitable depression; Round the clock ball 2 by two can involutory balling-up transparent material hemisphere make, one hemisphere transparent color, another ball is not colored as the bright state of full impregnated, be marked with one day time scale 22, behind the interior geographical pattern ball 3 of packing into, be fixed in the ball rotating shaft round the clock 21, the corresponding mouth 12 of the rotating shaft of ball round the clock on the base is inserted in ball rotating shaft round the clock 21, realizes that ball can vertically rotate around base round the clock; Support 4 is fixed on the support corresponding interface 11 of base 1.
In the geographical pattern ball 3 earth's axis positioning magnet 31,32 is installed, attract each other with stent magnet 41,42 corresponding on the support 4, make geographical pattern ball 3 form a virtual earth's axis, outer magnet 5 by with geographical pattern ball in the attraction of drive magnet 33, can drive geographical pattern ball and rotate, the rotation of the simulation earth.
At last, it is also to be noted that what more than enumerate only is a kind of specific embodiment of the present utility model.Obviously, the utility model is not limited to above embodiment, and many distortion can also be arranged.All distortion that those of ordinary skill in the art can directly derive or associate from the disclosed content of the utility model all should be thought protection domain of the present utility model.
