Detailed Description

In order to clearly illustrate the technical features of the present invention, the present invention is explained in detail by the following embodiments in combination with the accompanying drawings.

As shown in fig. 1-4, the globe of the embodiment comprises an earth model 1, wherein the earth model 1 is mounted on a base 3 through an arc-shaped support frame 2, the center of a circle of the arc-shaped support frame 2 coincides with the center of a sphere of the earth model 1, an earth model rotating shaft 4 arranged along the earth axis direction of the earth model 1 is arranged at the top of the arc-shaped support frame 2, a frustum-shaped rotating disc 5 is arranged at the bottom of the earth model rotating shaft 4, a rotating disc seat 6 rotatably sleeved on the outer side of the rotating disc 5 is arranged at the north pole point of the inner side of the earth model 1, the bottom end of the earth model rotating shaft 4 extends into the earth model 1 and then is connected with the rotating disc seat 6 through the rotating disc 5, a black hemispherical shell 7 is buckled on the outer side of the earth model 1, the edge of the black hemispherical shell 7 is connected with the arc-shaped support frame 2 through an arc-shaped rotating handle 9, the center of a circle of the arc-shaped rotating handle 9, offer a pivot slide 8 that supplies earth model pivot 4 to pass at the top of black hemisphere shell 7, the length of pivot slide 8 equals the spherical radius of earth model 1 north pole circle, arc turning handle 9 sets up with the terminal surface of black hemisphere shell 7 and arc support frame 2 respectively perpendicularly, and the one end tip of arc turning handle 9 links firmly with black hemisphere shell 7, and other end tip is equipped with a turning handle slide bar 10, is equipped with a slide bar slide 11 at the middle part of arc support frame 2, the length of slide bar slide 11 equals the spherical length of earth model 1 north pole circle, turning handle slide bar 10 passes slide 11 and links to each other with a fastening nut 12 after.

And latitude scale marks 13 are arranged on the surface of one side of the arc-shaped support frame 2.

The end part of the outer end of the rotating handle sliding rod is provided with a sun direct-radiation point pointer 14.

The earth model is hung on the arc-shaped supporting frame 2 through the matching of the turntable seat 6 and the turntable 5 on the earth model rotating shaft 4, and when the demonstration device is used, the earth model 1 rotates around the earth model rotating shaft 4, so that the autorotation motion of the earth can be demonstrated. The swing handle slide bar 10 can slide in the slide bar slideway 11 by loosening the fastening nut 12 on the swing handle slide bar 10. The rotation handle slide bar 10 moves to drive the direct sun point on the rotation handle slide bar 10 to move between the return line of south and north, thus showing the change of four seasons. The end face of the black hemispherical shell 7 is a morning and evening circle, the direct solar radiation point moves between the south and north return lines, and the morning and evening circle also rotates along with the rotation of the direct solar radiation point and the morning and evening circle, so that the internal relation of movement change between the direct solar radiation point and the morning and evening circle is embodied. For example, in winter solstice, the direct point of the sun is aligned with the line of return from south, and the black hemisphere shell covers the north pole circle completely, the north hemisphere is shorter in the daytime than at night, and the south hemisphere is longer in the daytime than at night. When the earth model 1 rotates, the morning and evening circle rotates relative to the earth model 1, so that the region on the earth model 1 generates day and night alternation.

The parts of the present invention not described in detail are the known techniques of those skilled in the art. Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
