Abstract

The utility model relates to a magnetic-repulsion time and day/night display terrestrial globe, which consists of a structure including an inner layer and an outer layer. A black-and-white backgroundball body is positioned in the inner layer, a transparent-face ball body is positioned in the outer layer and the geographical patterns are processed on the surface of the transparent-face ball body.The utility model is characterized in that a magnet is mounted inside the black-and-white background ball body, and the other magnet outside the transparent-face ball body drives the black-and-white background ball body to rotate through the interactive action of the magnets; and local-time scales of one day, which correspond to each longitude, are carved on the outer surface of the black-and-white background ball body. 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 of the 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

Magnetic-repulsion shows time and terrestrial globe round the clock

Technical field

The present invention relates to a kind of terrestrial globe, particularly relate to a kind of magnetic-repulsion and show time and terrestrial globe round the clock.

Background technology originally

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.

Summary of the invention

The present invention provides a kind of magnetic-repulsion to show time 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 present invention realizes by following measure: this magnetic-repulsion shows time and terrestrial globe round the clock, comprise base, support, can be fixed on the disloyalty rotating shaft at support two ends, the black and white background spheroid that can rotate around positive heart rotating shaft, can be around the transparent print face ball of oblique heart rotating shaft rotation; Support is installed on the base, and the disloyalty rotating shaft is installed in the support two ends, and black and white background spheroid is installed in the positive heart rotating shaft of disloyalty rotating shaft, on be coated with black and white half and half color, be in internal layer; The transparent print face ball is installed in the oblique heart rotating shaft of disloyalty rotating shaft, on the geographical pattern of the transparent earth is arranged, be in skin.It is characterized in that a magnet is installed in black and white background spheroid inside, another magnet rotates by the discontiguous drive black and white of the interaction force background spheroid between magnet outside the transparent print face ball.

Described black and white background outer surface of spheroid is marked with one day time scale.

Because the transparent print face ball and on geographical pattern be transparent, want the backrest scape to set off out pattern, the black and white background spheroid of the inside can set off out the black and white effect, transparent print face ball pattern under the white background is analysed bright clearly, representative is in the state on daytime, and the transparent print face ball pattern under the black background is intensely dark, represents the state at night, thereby show the state round the clock of the earth, and detect residing local time according to the time scale on the black and white background spheroid.Black and white background spheroid can rotate as required, and the user can forward black and white background spheroid to destination locations by outer magnet, thereby embody in good time earth state according to the imagination position relation of the earth and the sun.

The present invention has solved the state 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.

Embodiment

The present invention will be further described below in conjunction with example and accompanying drawing:

As shown in Figure 1, be apparatus of the present invention structural representation.This black and white globe is made up of base 1, support 2, disloyalty rotating shaft 3, transparent print face ball 4, black and white background spheroid 5, support 2 is installed on the base 1, disloyalty rotating shaft 3 is installed on 21,22 corresponding apertures of support two ends by screw, black and white background spheroid 5 is installed in the positive heart rotating shaft of disloyalty rotating shaft 3, a magnet 56 is installed in the black and white background spheroid 5, magnet 57 can not promote black and white background spheroid 5 and rotates by not contacting with the effect of the magnetic force of magnet 56, and transparent print face ball 4 is installed in the oblique heart rotating shaft of disloyalty rotating shaft 3.

As shown in Figure 2, examples of implementation for disloyalty rotating shaft 3 of the present invention, disloyalty rotating shaft 3 has changed common terrestrial globe and has had only an axial central rotating shaft structure, has become to have two axial rotating shafts, that is: with the vertical positive heart rotating shaft and the oblique heart rotating shaft that becomes 66.5 degree angles with surface level of surface level.Be provided with the protruding 33,34 of location black and white background spheroid 5 above the disloyalty rotating shaft 3, location transparent print face ball 4 protruding 35,36 is used for this is fixed on hole 31,32 on the support.During installation, with on 21,22 pairs in the hole on hole in the disloyalty rotating shaft 3 31,32 and the support, load onto corresponding screw or latch, disloyalty rotating shaft 3 just can be fixed on the support 2.Disloyalty rotating shaft 3 can also can be adopted the method for sectional making according to the arts demand of making by once-forming, is formed by connecting after the branch plurality of sections is carried out, as long as enough firmly again.
