Abstract

The utility model relates to a moon phenomenon formation reason demonstration instrument for children and science popularization, which is formed by assembling a rotating disc, a static disc, a rotating shaft, an earth model, a human model and a pressing ring along a common axial cord, wherein the rotating shaft, the earth model and the human model are fixed together; the pressing ring can be sheathed at the top end of the rotating shaft; the rotating shaft is divided into two sections according to diameter sizes, wherein one section with a big diameter is tightly matched with the rotating disc to be sheathed on a center hole of the rotating disc, the other section with a small diameter passes through a center hole of the static disc and the end part of the rotating shaft is sheathed on the pressing ring. The static disc is externally connected with a rectangular slice with an arrow head, eight moon phase pictures are distributed on the outer circle of the static disc and eight moon light receiving pictures are distributed on the inner circle. The corresponding positions of the rotating disc are provided with moon phase windows and moon light receiving picture frames. The utility model has the advantages of low cost and convenient assemblage, and can be conveniently popularized among children and teenagers.

Description

Children and science popularization phases of the moon origin cause of formation demonstrator

The utility model relates to a kind of exploitation children intelligence, makes it know that the moon centers on the teaching aid of the origin cause of formation of the revolution of earth motion and the phases of the moon, especially a kind of children and science popularization phases of the moon origin cause of formation demonstrator.

Existing this quasi-instrument, complex structure costs an arm and a leg, and it is big to put floor area, is not that general family or school can bear.

The purpose of this utility model is that design is a kind of with low cost, easy to assembly, be convenient to the phases of the moon origin cause of formation demonstrator of penetration and promotion in children, make children know that the moon is around the revolution motion of the earth and the origin cause of formation of the phases of the moon by demonstration, start experimental ability, inferential capability and visionary with what cultivate children.

Below in conjunction with accompanying drawing 1-2 scheme of the present utility model is narrated:

Earth model (6) and human model (5) that the utility model mainly is fixed together by rotating disk (7), quiet dish (9), rotating shaft (4) and rotating shaft and the trim ring (10) that can be enclosed within rotating shaft (4) top are assembled along common axis line; Rotating shaft (4) is divided into two sections 4a and 4b by diameter, and one section (4a) that diameter is bigger is placed on the center of turntable hole (3), and is mated, the center pit (8) that a section (4b) that diameter is little passes quiet dish (9) be placed in that trim ring (10) is gone up and with its wringing fit; The external rectangular sheet that indicates the arrow of representing the sunshine direction of quiet dish (9), be distributed with eight width of cloth moons identical (12) round axis hole (8) outer ring, corresponding this eight width of cloth lunar chiaroscuro (12), inner ring is distributed with eight width of cloth moon and is subjected to light figure (11), face the position of going up lunar chiaroscuro (12) corresponding to quiet dish (9) in the human model front on the rotating disk (7) and have phases of the moon window (1), have the moon and be subjected to the light picture frame corresponding to the land on the moon place that is subjected to light figure (11) of quiet dish (9).

Utilizing the demonstrator of said structure to observe moon circle in one month lacks and changes, the sunshine that the rotating disk upward arrow indicates is represented the sun, people and earth model are represented the earth, rotate rotating disk and relatively can demonstrate the situation of change of the moon around a month process reflected sunlight of revolution of earth, from the phases of the moon origin cause of formation instrument as can be seen, the moon is in the revolution process, one side towards the earth, sometimes all become clear, sometimes light is greater than dark part, half-and-half sometimes, and light is less than dark part sometimes, sometimes black entirely, can see the variation that the phases of the moon is arranged so on earth.

The utility model has the advantages that with low cost, easy to assembly, good demonstration effect, be convenient in children, popularize and use, make children know the origin cause of formation of the circumterrestrial revolution motion of the moon and the phases of the moon.

Description of drawings:

Fig. 1 is a schematic perspective view of the present utility model;

Fig. 2 is a front elevation of the present utility model.

Embodiment: Fig. 1-2 is an enforcement illustration of the present utility model, its structure is as indicated above, make used starting material, rotating disk (7) and quiet dish (9) all use colored card paper to make, rotating shaft (4) and earth model (6), trim ring (10) are used injection molding, human model can be imprinted on and be bonded on the card paper on the earth model, also can with the earth model single injection-molded.Represent arrow, phases of the moon circle, the moon of sunshine to be subjected on light figure and the lunar chiaroscuro target the first day of the lunar month, the 15th day of a lunar month and wind up, lower edge is printed on the quiet dish (9), the arrow that rotates counterclockwise of expression is arranged on the rotating disk (7), and it is the breach of leaving on the rotating disk (7) that human model is subjected to light picture frame (2) facing to phases of the moon window and the moon.

Claims (1)

1, a kind of children and science popularization is with phases of the moon origin cause of formation demonstrator, it is characterized in that earth model (6) and human model (5) that it is fixed together by rotating disk (7), quiet dish (9), rotating shaft (4) and rotating shaft and the trim ring (1 0) that can be enclosed within rotating shaft (4) top are assembled along common axis line; Rotating shaft (4) is divided into two sections 4a and 4b by diameter, and one section (4a) that diameter is bigger is placed on the center of turntable hole (3), and is mated, the center pit (8) that a section (4b) that diameter is little passes quiet dish (9) be placed in that trim ring (10) is gone up and with its wringing fit; The external rectangular sheet that indicates the arrow of representing the sunshine direction of quiet dish (9), be distributed with eight width of cloth moons identical (12) round axis hole (8) outer ring, corresponding this eight width of cloth lunar chiaroscuro (12), inner ring is distributed with eight width of cloth moon and is subjected to light figure (11), face the position of going up lunar chiaroscuro (12) corresponding to quiet dish (9) in the human model front on the rotating disk (7) and have phases of the moon window (1), have the moon and be subjected to the light picture frame corresponding to the land on the moon place that is subjected to light figure (11) of quiet dish (9).
