Abstract
The utility model discloses a demonstrator for moon phase formation. The demonstrator is characterized in that a back shaft is arranged on a tripod, the middle portion of the back shaft is provided with a fixed belt pulley, a large sleeve sleeves the upper end of the back shaft, a spring telescopic rod is arranged at one side of the large sleeve, a rotary belt pulley is arranged at the other end of the spring telescopic rod via a rotary shaft, a small sleeve sleeves the upper end of the rotary shaft, and a black and white moon model is arranged over the small sleeve. Thus, the demonstrator can demonstrate the moon phases as well as the changing process of the moon phases, thereby enabling students to thoroughly understand reasons of different moon phases, effectively helping teaching of the moon phase formation, making teaching simpler, and providing convenience for understanding and mastering of the students.
Description
Technical field
The utility model relates to a kind of demonstration teaching aid, is that a kind of phases of the moon that can demonstrate phases of the moon forming process forms demonstration device specifically.
Background technology
In the phases of the moon teaching of school science and middle school geography, existing equipment all can not be demonstrated the forming process of the phases of the moon well.As too little in three-globe instrument, may not demonstrate out the phases of the moon.And phases of the moon variation model can only be seen the various phases of the moon well, how to form and can not demonstrate for the phases of the moon.
Summary of the invention
The phases of the moon that the purpose of this utility model is to provide a kind of energy ocular demonstration phases of the moon and forming process thereof forms demonstration device.
To achieve these goals, the utility model is provided with back shaft in the upper end of three leg supports, middle part at back shaft is provided with fast pulley, large casing pipe sleeve is in back shaft upper end, described large sleeve pipe can rotate on back shaft, a side at large sleeve pipe is provided with telescopic spring bar, rotation belt pulley is located at the other end of telescopic spring bar by rotating shaft, described fast pulley is identical with the size of rotation belt pulley, belt is connected fast pulley with rotation belt pulley, in the upper end of rotating shaft, cover has small casing, described small casing and rotating shaft are integrated, black and white moon model is located at the top of small casing.
By above setting, the utility model can be demonstrated the phases of the moon, can demonstrate out again the process of month phase change very visual in imagely, make student thoroughly understand the reason that forms the different phases of the moons, effectively help through the teaching that the phases of the moon forms, allow teacher teach simply, be convenient to student's understand and master.
Accompanying drawing explanation
Now the utility model is described in further detail by reference to the accompanying drawings.
Fig. 1 is structural representation of the present utility model.
In figure: 1, three leg supports, 2, back shaft, 3, fast pulley, 4, large sleeve pipe, 5, telescopic spring bar, 6, rotation belt pulley, 7, rotating shaft, 8, belt, 9, small casing, 10, black and white moon model.
Embodiment
As shown in Figure 1, the utility model is provided with back shaft 2 in the upper end of three leg supports 1, be provided with fast pulley 3 in the middle part of back shaft 2, large sleeve pipe 4 is enclosed within back shaft 2 upper ends, described large sleeve pipe 4 can rotate on back shaft 2, a side at large sleeve pipe 4 is provided with telescopic spring bar 5, rotation belt pulley 6 is located at the other end of telescopic spring bar 5 by rotating shaft 7, described fast pulley 3 is identical with the size of rotation belt pulley 6, belt 8 is connected fast pulley 3 with rotation belt pulley 6, in the upper end of rotating shaft 7, cover has small casing 9, described small casing 9 and rotating shaft 7 are integrated, black and white moon model 10 is located at the top of small casing 9.By above setting, the white hemisphere of the utility model black and white moon model 10 represents the part that the moon is illuminated by the sun, black hemisphere represent the sun according to less than part.When demonstration, when the phases of the moon, regulating spring expansion link 5, towards North and South direction, regulates the white hemisphere of black and white moon model 10 towards Due South, positive the south is the sun, and the sight moon person who now stands in support place can see a complete black hemisphere face, represents the junior one monthly, can't see the moon, phases of the moon name is called crescent.45 ° of telescopic spring bar 5 is counterclockwise slow circumvolves, rotation belt pulley 6 rotates under the drive of fast pulley 3, and drives black and white moon model 10 to rotate together, makes the white hemisphere of black and white moon model 10 all the time towards south, observer can see that white hemisphere is crescent shaped, i.e. a cresent.Continuing to rotate to 90 °, can see that white hemisphere just accounts for global half, is the moon at the first quarter.Continuing to rotate to 135 °, can see that white hemisphere accounts for the whole world most of, is gibbous moon.Continuing to rotate to 180 °, can see whole white hemisphere, is full moon.Continuing to rotate to 225 °, see that it is gibbous moon that white hemisphere accounts for global major part, continue to rotate to 270 °, see that white hemisphere accounts for half, is the moon at the last quarter.Continuing to rotate to 315 ° and see that white hemisphere is crescent shaped, is cresent.So far seen the change procedure of the phases of the moon in month.
Can find out by above demonstration, when first half of the month, the right side of the moon is bright, and when the second half of the month, the left side of the moon is bright.The reason that the phases of the moon forms is: the moon is an opaque spheroid, and the sun can only illuminate its one side, and in the time that the moon arrives diverse location around revolution of earth, tellurian people can see that bright size and bright the direction of the moon are changing, the phases of the moon that Here it is.
