Abstract
The utility model discloses a teaching demonstrator for the rotation and revolution of the earth. The teaching demonstrator for the rotation and revolution of the earth comprises a base, wherein a heliometer is arranged on the base in a supporting manner via a support; a rail is arranged at the periphery of the heliometer in a surrounding manner; a rail groove is formed in the rail; a gear ring is arranged in the rail groove; a gear engaged with the gear ring is further arranged in the rail groove; a transmission device is slidably arranged on the rail; the transmission device is connected with a tellurion; the gear is connected with the transmission; the tellurion is driven by the transmission device to rotate, so as to demonstrate the rotation of the earth, and is rotated with the gear connected with the transmission device simultaneously, and the tellurion advances in the rail groove and moves around the heliometer during rotation of the gear, so as to demonstrate the revolution of the earth. The teaching demonstrator for the rotation and revolution of the earth disclosed by the utility model is used for teaching demonstration for the geography department, as well as capable of visually demonstrating the rotation and revolution of the earth, causing teaching to be vivid and visual, increasing the learning interest of students, and ensuring teaching quality.
Description
Technical field
The utility model relates to a kind of teaching aid, relates in particular to a kind of geographical course teaching apparatus.
Background technology
The rotation of the earth and revolution are important knowledge points of geographical subject, main oral explanation or the explanation of cooperation wall chart by teacher in existing teaching, but rotation and revolution that like this can not the playback image earth, day alternates with night and seasonal variations for playback image, teaching is dull uninteresting, actively the enthusiasm of mobilizing students causes teaching efficiency relatively poor.
The utility model content
Technical problem to be solved in the utility model provides a kind of teaching demonstration for geographical subject, can demonstrate rotation and the revolution of the earth visually, make teaching vivid, increase students'interest in learning, guarantee the earth rotation revolution demonstration instrument for teaching of quality of instruction.
For solving the problems of the technologies described above, the technical solution of the utility model is: earth rotation revolution demonstration instrument for teaching, comprise base, be provided with solar attachment by stent support on the described base, all side rings of described solar attachment are arranged with track, described track is provided with rail groove, be provided with gear ring in the described rail groove, also be provided with in the described rail groove and described gear ring meshed gears, sliding on the described track is provided with gearing, described gearing is connected with terrestrial globe, and described gear connects described gearing.
As optimized technical scheme, described gearing comprises transmission case, the upper and lower of described transmission case is respectively equipped with output revolving shaft, the output revolving shaft that is positioned at described transmission case top connects described terrestrial globe, the output revolving shaft that is positioned at described transmission case bottom connects described gear, and described transmission case is connected with turning handle.
As to further improvement in the technical proposal, described track is elliptical orbit.
Owing to adopted technique scheme, earth rotation revolution demonstration instrument for teaching, comprise base, be provided with solar attachment by stent support on the described base, all side rings of described solar attachment are arranged with track, described track is provided with rail groove, be provided with gear ring in the described rail groove, also be provided with in the described rail groove and described gear ring meshed gears, sliding on the described track is provided with gearing, described gearing is connected with terrestrial globe, and described gear connects described gearing.Operate described gearing, described terrestrial globe is driven by described gearing and rotates, demonstrate the rotation of the earth with this, the described gear that is connected with described gearing simultaneously rotates, owing to be provided with gear ring in the described rail groove, described gear and the engagement of described gear ring can be advanced in described rail groove when described gear rotates, around described solar attachment motion, so just demonstrate revolution of earth simultaneously.The utility model is used for the teaching demonstration of geographical subject, can demonstrate rotation and the revolution of the earth visually, makes teaching vivid, increases students'interest in learning, guarantees quality of instruction.
Description of drawings
The following drawings only is intended to the utility model done and schematically illustrates and explain, does not limit scope of the present utility model.Wherein:
Fig. 1 is the structural representation of the utility model embodiment.
