Abstract
A kind of independent assortment celestial body teaching demonstration device, comprises base and support, arranges two with upper bracket pickup groove on described base, and described support is flexibly connected with support pickup groove, and support upper end connects model of celestial bodies.Also comprise celestial bodies motion model rail, described celestial bodies motion model rail is supported by more than two cantilever tip, and model of celestial bodies is slidably connected on described celestial bodies motion model rail.Independent assortment celestial body teaching demonstration device described in the utility model arranges two with upper bracket pickup groove on base, and described support is flexibly connected with support pickup groove, and support upper end connects model of celestial bodies.So both can arbitrarily combine model of celestial bodies, and no time, model can have been accepted, and greatly save space, the parcel tray carrying below has also improved convenient function.
Description
Technical field
The utility model relates to a kind of instruments used for education, especially relates to a kind of independent assortment celestial body teaching demonstration device.
Background technology
the rotation of celestial body is an important knowledge point in Geography, but in existing teaching, only rely on teacher's oral explanation, the explanation of cooperation wall chart, be can not image reproduction celestial body between position and kinematic relation, the student that allows that can not image understands that between celestial body, day alternates with night, and time change etc., teaching is dull uninteresting, and the actively enthusiasm of mobilizing students, causes teaching efficiency poor.
Granted publication number is the patent of CN 203149995 U, a kind of earth rotation revolution demonstration instrument for teaching is disclosed, by stent support solar attachment, in solar attachment week, track is put in side ring winding, utilize rail groove is set in orbit, the gearing such as gear ring, gear is set in rail groove, the mode of terrestrial globe is installed on gearing, come rotation and the revolution of the analog demenstration earth.But the rotating manner more complicated of this earth rotation revolution demonstration instrument for teaching, needs first to shake in orbit driving handle, the output revolving shaft of transmission case is rotated, driven gear and terrestrial globe rotate, and just can reach the demonstration purpose of earth rotation and revolution.
In addition, due to gearing complexity, the track arranging in patent is also wider, can be easy to obstruct the view, and is unfavorable for observing better teaching process.
Have again, the characteristic of celestial body self has multiple, comprise self characteristics of luminescence of celestial body, above-mentioned patent can not be covered up this characteristic, and the patent of license notification number CN 203070669 U is installed light source on solar attachment, although solved the problem of astrospectroscopy characteristic demonstrating, but this patent is, at the two ends of same swivel arm, solar attachment and terrestrial globe are set respectively, but movement of heavenly bodies track is different oval or other shapes, and in this patent, well demonstration is not arrived.
Summary of the invention
in order to overcome the deficiency in background technology, the utility model discloses a kind of celestial body demonstration instrument for teaching.
In order to realize described utility model object, the utility model adopts following technical scheme: a kind of independent assortment celestial body teaching demonstration device, comprise base and support, on described base, arrange two with upper bracket pickup groove, described support is flexibly connected with support pickup groove, and support upper end connects model of celestial bodies.
Independent assortment celestial body teaching demonstration device described in the utility model also comprises celestial bodies motion model rail, and described celestial bodies motion model rail is supported by more than two cantilever tip, and model of celestial bodies is slidably connected on described celestial bodies motion model rail.
Sphere described in the utility model is circular or oval.
In support pickup groove described in the utility model, screw thread is set, the lower end of described support is provided with the screw matching with pickup groove internal thread.
The model of celestial bodies axis of rotation that is slidably connected on celestial bodies motion model rail described in the utility model, described model of celestial bodies is enclosed within on the model of celestial bodies axis of rotation.
Base described in the utility model below is provided with parcel tray.
The inside of model of celestial bodies described in the utility model arranges light source.
Owing to having adopted technique scheme, the utlity model has following beneficial effect: independent assortment celestial body teaching demonstration device described in the utility model, on base, arrange two with upper bracket pickup groove, described support is flexibly connected with support pickup groove, and support upper end connects model of celestial bodies.So both can arbitrarily combine model of celestial bodies, and no time, model can have been accepted, and greatly save space, the parcel tray carrying below has also improved convenient function.
For some luminous or catoptrical celestial bodies own, as the sun, the moon etc., in model of celestial bodies, place light source, can more directly observe the irradiation reflection case of celestial body to light.
