Abstract

A demonstration model toy for four seasons of earth comprises a base, supporting rods, a tellurion, a disc and a sun sphere. The conical base is provided with four supporting rods which respectively incline frontwards, backwards, leftwards and rightwards. The upper part of each supporting rod is provided with an N-shaped elbow for supporting the disc. The top end of the N-shaped elbow of each supporting rod is provided with an insertion tube. The axis of each insertion tube is at an angle of 23DEG-26SEC to the plane of the disc. Only one tellurion with a shaft at two ends is arranged on four insertion tubes through insertion. The center of the disc is provided with a circular hole where the sun sphere is arranged. The sun sphere is composed an upper half sphere housing and a lower half sphere housing. The lower half sphere housing is fixed in the circular hole of the disc. The upper half sphere housing is concentric with the disc and furthermore can rotate. The upper half sphere housing is internally provided with a miniature laser designator. The switch for the laser designator is arranged at the top of the upper half sphere housing. The demonstration model toy for four seasons of the earth can make persons visually observe changes among four seasons of the earth through specific demonstration, so that the persons can understand the four-season change principle of the earth. The demonstration model toy can be used as a toy as well as a teaching aid for teaching geography.

Description

Earth four seasons demonstrating model toy

Technical field

The invention belongs to toy technique field, specifically a kind of model toy that can demonstrate earth spring, summer, autumn and winter Four seasons change.

Background technology

At present, the knowledge of earth spring, summer, autumn and winter Four seasons change has been done the explanation of word and picture in geographical book, is very abstract, and for the limited people of imagination, this abstract explanation is very indigestible; Also there is geographical teacher with One Earth One Family instrument, a ruler and three article of a ball, ball to be placed on desk face, the variation principle in hand-held tellurion and ruler explanation four seasons earth spring, summer, autumn and winter, because tellurion, ruler and ball are respectively three not article of disjunctor, with hand-held be to be difficult in one plane, so still can not allow people see intuitively the Four seasons change demonstration of earth spring, summer, autumn and winter.

Summary of the invention

This technical problem that will solve is that a kind of model toy that can allow people see intuitively the Four seasons change demonstration of earth spring, summer, autumn and winter is provided.

The technical scheme that the present invention takes is: earth four seasons demonstrating model toy, it comprises base, support bar, tellurion, disk, sun ball, it is characterized in that: on a sloped footing, have four support bars that tilt forwards, backwards respectively, the top of each support bar has " N " shape curved for support disk, the curved top of " N " shape of each support bar is an intubate, the axial line of each intubate and the plane of disk be 23 ° 26 ' angle, in four intubate, only plug in the tellurion of a two ends tape spool, disc centre has a circular hole, on circular hole, there is a sun ball, sun ball is made up of upper and lower hemispheres shell, sun ball lower hemisphere shell is fixed in disk hole, upper hemispherical shell and disk concentric and can rotate, the interior horizontal miniature laser indicator that has of upper hemispherical shell, the switch of laser designator is on the top of upper hemispherical shell.

Further, the tellurion of above-described two ends tape spool, is printed on " earth " word and " equatorial line ", " tropic of Capricorn ", " tropic of cancer " on its surface, above-described disk, place and be printed on a loop line at its circle, at the other word that is printed on " earth 's orbit line " of loop line, other being printed on respectively " Autumnal Equinox " of support bar all around in its surface, " Spring Equinox ", the word in " Winter Solstice " and " Summer Solstice ", on the face of the middle part of disk, be printed on the word of " earth 's orbit face ", appropriate location in disc face is printed on that " earth is rotation and revolution on revolution orbit, always remain earth axis and earth 's orbit face be 23 ° 26 ' angle, all the time namely " body sideling " revolves round the sun and rotation on earth 's orbit face " etc. the word of associated knowledge, above-described sun ball, is printed on the word of " sun " thereon on hemispherical Shell face.

With produced this toy of above technical scheme, in the time playing, the lower shaft of tellurion is inserted in the intubate of back support rod, press the laser designator switch on sun ball top, rotate the upper hemispherical shell of sun ball, just the laser rays directive tellurion of laser designator, at this moment just can see the equatorial line of laser rays direct projection tellurion, the upper axle rotating the globe with hand, can demonstrate the rotation of the earth, in the time that tellurion rotates (earth rotation), laser rays (sunray) remains direct projection equatorial line, and what demonstrated this position is the season of the earth Northern Hemisphere in spring; The lower shaft of tellurion is inserted in the intubate of right support bar, rotate the upper hemispherical shell of sun ball, the ray shoots that makes laser designator is during to tellurion, at this moment just can see the tropic of cancer of laser rays direct projection tellurion, the laser rays (sunray) that rotates the globe remains the direct projection tropic of cancer, and what demonstrated this position is the season of the earth Northern Hemisphere in summer; The lower shaft of tellurion is inserted in the front intubate of front support rod, the upper half shell that rotates sun ball, makes the ray shoots of laser designator to the equatorial line of tellurion, rotates the globe, still direct projection equatorial line of laser rays (sunray), what demonstrated this position is the season of the earth Northern Hemisphere in autumn; The lower shaft of tellurion is inserted in left intubate, rotate the upper half shell of sun ball, make the ray shoots of laser designator to the tropic of Capricorn of tellurion, at this moment just can see the tropic of Capricorn of laser rays direct projection tellurion, rotate the globe, the still direct projection tropic of Capricorn of laser rays (sunray), what demonstrated this position is the season of the earth Northern Hemisphere in winter.

The invention has the beneficial effects as follows: this ground ball toy can allow people see intuitively and demonstrate particularly the variation in the earth four seasons, allow people be more readily understood the principle of earth Four seasons change, both can work as toy, can work as again religion geographical teaching aid.
