Description

Inner structure of day and night demonstration globe

Technical Field

The utility model relates to a globe technical field, in particular to demonstrate inner structure of globe round clock.

Background

The globe is a tool for displaying the geographical conditions of the earth and the position distribution of each country and region, and is often used in teaching and scientific research, in particular to a teaching instrument which is necessary for teaching of middle and small-sized scientific courses. The existing globe is simple, and comprises a base, a bracket and a central rotating shaft fixed on the bracket, wherein a sphere capable of simulating the rotation of the earth is arranged on the central rotating shaft, and each country and region are drawn on the sphere according to geographical distribution. However, the earth also revolves around the sun for one year and a period, which results in that we feel spring, summer, autumn and winter and sunrise and sunset every day year after year. The existing globe can reflect the rotation of the earth, but the globe cannot reflect the day and night distribution condition formed by the relation between the globe and the sun when the earth rotates, so that students cannot easily understand the day and night changing state of the earth. At present, the globe which is supposed to show the day and night state on the globe is also provided, but the light screen is complex to manufacture, high in cost and high in requirements on materials.

SUMMERY OF THE UTILITY MODEL

The technical problem to be solved by the utility model is to overcome the defect that the light screen is complex to manufacture and provide an internal structure of a day and night demonstration globe.

In order to solve the technical problem, the utility model provides a following technical scheme: the utility model provides an inner structure of demonstrating globe round clock, includes fixed bolster, globe shell and light screen, the light screen be with globe shell assorted circular slab, be provided with the opening under the light screen, be equipped with the fixed bolster outside the globe shell, be equipped with the light screen in the globe shell, the light screen is connected with the ground axle, ground axle one end is equipped with the regulation pole, the regulation pole passes the ground axle to be connected with the light screen, the light screen both sides are equipped with the light source, the ground axle other end is equipped with the power cord, the power cord is connected with the light source, be equipped.

The utility model discloses the beneficial effect who reaches is: set up the regulation pole, the distance between adjustable light screen and the earth axis provides convenience round the clock to the demonstration, and the regulation principle is simple, and convenient operation has enlarged the teaching function of globe for people master the knowledge that the earth formed round the clock easily, and the regulation pole is twitched along the direction of earth axis, and the angle between adjustable light screen and the earth axis through the control light source, can demonstrate half daytime and half night of earth, provides convenience round the clock to control the globe.

reference numbers in the figures: 1. fixing a bracket; 2. a ground shaft; 3. adjusting a rod; 4. a globe housing; 5. a visor; 6. a power line; 7. a power switch; 8. an opening; 9. a light source.

Detailed Description

The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.

In the description of the present invention, it should be noted that the terms "vertical", "upper", "lower", "horizontal", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention.

In the description of the present invention, it should also be noted that, unless otherwise explicitly specified or limited, the terms "disposed," "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

Example (b): as shown in fig. 1-2, the utility model provides an inner structure of demonstrating globe round clock, including fixed bolster 1, globe shell 4 and light screen 5, light screen 5 be with globe shell 4 assorted circular slab, be provided with opening 8 under the light screen 5, globe shell 4 is equipped with fixed bolster 1 outward, be equipped with light screen 5 in the globe shell 4, light screen 5 is connected with ground axle 2, the one end of ground axle 2 is equipped with adjusts pole 3, it passes ground axle 2 and is connected with light screen 5 to adjust pole 3, light screen 5 both sides are equipped with light source 9, the ground axle 2 other end is equipped with power cord 6, power cord 6 is connected with light source 9, be equipped with switch 7 on the power cord 6. Set up regulation pole 3, the distance of adjustable light screen 5 and earth's axis 2, and opening 8 size is moderate, does not influence demonstration earth half night and half daytime, and the regulation pole 3 is twitched along the direction of earth's axis 2, and the lower extreme of earth's axis 2 can pass opening 8, adjusts the angle between light screen 5 and the earth's axis 2, through light source 9, can demonstrate earth half daytime and half night, provide convenience round the clock to control the globe, and 5 simple manufactures of light screen are with low costs.

Example 2: on the basis of embodiment 1, the shape of the fixing bracket 1 is various and can be changed according to the preference of people, such as a circular ring, a semicircular ring, a semispherical ring and the like.

Example 3: in addition to embodiment 1, the adjusting rod 3 is inserted from the upper end of the ground shaft 2, and then the adjusting rod 3 is passed out from the ground shaft 2 and fixedly connected with the light shielding plate 5, and the adjusting rod 3 can also be inserted from the lower end of the ground shaft 2 and fixedly connected with the light shielding plate 5.

Example 4: on the basis of embodiment 1, the ground shaft 2 may be located inside or outside the light shielding plate 5, and the ground shaft 2 is located at one side of a vertical line of the opening 8, and one end of the ground shaft 2 may pass through the opening 8 when the adjusting lever 3 is pulled.

Specifically, this kind of light barrier that demonstrates globe round clock theory of operation is that, opening 8 size is moderate, and 5 one side light source 9 of light barrier are bright the time, can not exert an influence to the opposite side, also do not influence demonstration earth half night and half daytime exactly, and regulation pole 3 is twitched along the direction of earth axle 2, and opening 8 can be passed to the lower extreme of earth axle 2, adjusts the angle between light barrier 5 and the earth axle.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
