Description

Phases of the moon change demonstration device
Technical field
The utility model relates to the teaching demonstration field of tool, is a kind of phases of the moon change demonstration device that can simulate the moon around the moon of revolution of earth phase change specifically.
Background technology
As everyone knows, the earth revolves round the sun around the sun, and the moon is around revolution of earth; When the moon is around revolution of earth; Tellurian people can see the reflected light from the moon, and this reflected light demonstrates the different phases of the moons, and reflected light is that the moon produces under the irradiation of the sun.The moon different position of revolving round the sun, its phases of the moon also change thereupon, eight kinds of phases of the moons can occur: crescent, go up crescent, the moon at the first quarter, gibbous moon, full moon, waning moon, the moon at the last quarter, crescent down.Begin from middle and primary schools, school just begins to be provided with courses such as geography or natural general knowledge, and teacher need lecture celestial body knowledge to the student, also comprises the variation and the origin cause of formation of the phases of the moon certainly.Therefore, in teaching, need phases of the moon change demonstration device to come aided education, through the simulation moon around revolution of earth and demonstrate the different phases of the moons, thereby deepen the student to of the understanding of the phases of the moon origin cause of formation with month phase change.The phases of the moon change demonstration device of prior art generally all adopts one and half black half white beads to simulate the moon; And it is revolved round the sun around earth model; And through the variation of periscope from earth model observation bead; Why will adopt half black half white bead, be that observed white part is exactly the phases of the moon in the periscope because that white face is the one side that receives solar light irradiation.
Yet in the above-mentioned prior art, moon model generally all adopts connecting rod and belt wheel mechanism to realize around earth model revolution, promptly comes drivening rod through manual or electronic, thereby makes the belt wheel mechanical operation, revolves round the sun around earth model with the realization moon model.Like the disclosed number of patent application of State Intellectual Property Office is the utility model patent " phases of the moon origin cause of formation demonstration instrument for teaching " of " 200920036034.0 "; Moon model in this patent is made up of driving wheel, engaged wheel, travelling belt, vertical rod, cross bar, crank around the operating control device of earth model, and driving and driven wheel shaft erectly is fixed on the base plate; Crank is fixed on the wheel face of driving wheel, and an end of cross bar is fixed on the wheel face of engaged wheel, and the other end is connected the bottom of vertical rod, the top of vertical rod be connected moon model under.It is thus clear that the moon model in the phases of the moon demonstrator of above-mentioned prior art is out of order around the mechanism structure more complicated of earth model easily, thereby poor reliability, and moon model is steady inadequately in motion, thereby influences the observing effect of the phases of the moon.
The utility model content
The technical matters that the utility model will solve is, provide a kind of simple in structure, reliability is high, and moon model can be reposefully around the phases of the moon change demonstration device of earth model motion.
The technical solution of the utility model is; A kind of phases of the moon change demonstration device of following structure is provided, comprises housing, moon model and periscope, be provided with the axle of two parallel placements in the described housing; Be provided with cross bar between described two axles perpendicular to axle; The two ends of described cross bar slidably are connected with two axles respectively, vertically are provided with a connecting rod on the cross bar, and described connecting rod slidably is connected with cross bar; Described moon model is fixed on the top of connecting rod, and described housing is provided with a circuit orbit.
Adopt above structure, the utility model compared with prior art has the following advantages: adopt the utility model structure, cross bar is the front and back motion on diaxon, simultaneously; Connecting rod is side-to-side movement on cross bar, and therefore, connecting rod can drive moon model arbitrary motion in certain planar range, owing to be provided with circuit orbit; When using the utility model,, make it make circular motion, at this moment along track with the hand moon model that fluctuates; In periscope, observe the variation of moon model, just can simulate the variation of the phases of the moon, can see eight kinds of phases of the moons successively, and can be according to problems such as the model explanation phases of the moon origin causes of formation; The utility model is not only simple in structure, and reliability is high, and failure rate is low, and has adopted this TRAJECTORY CONTROL of moon model stably mechanism; Make moon model in the process of motion, very steady, be convenient to the observation of the phases of the moon.
As improvement, the top of described housing has circular trough, and described circular trough is exactly described circuit orbit; Described connecting rod places in the circular trough, and described moon model is positioned at the circular trough top, like this; During use, only need to stir moon model and get final product along circular trough, very easy to use.
As improvement, the top of described housing is recessed circular, like this, can avoid the interference of too much extraneous light, makes moon phase change more obvious, and simultaneously, recessed portion can also serve as circuit orbit, makes the adherent motion of moon model can make circular motion.
As improvement, described moon model is half black half white bead, is convenient to the observation of the phases of the moon.
As improvement, the axle of described two parallel placements is positioned at the inner bottom part of housing, and the two ends of every axle all are fixed on the inner bottom part of housing through support, and such design is that the moon model operation is more steady.
As improvement, described cross bar passes through bearing and is connected with axle sleeve with being meant the two slidably being connected of axle, and connection is very steady like this, and resistance is little, is convenient to operation.
As improvement, described outer casing underpart is provided with base, and base is connected through axle with shell.When operating this device, when the rotation periscope, the people need move along with periscope.After being provided with base, then the people can not move, and only needs rotating base just passable.
