a globe

Abstract

The invention relates to the field of teaching display appliances, in particular to a globe. In geography teaching, it is often necessary to judge the time of sunrise and sunset through the change of seasons, and an auxiliary teaching aid that can show day and night and help students observe the time of sunrise and sunset is needed. In order to solve the above problems, the present invention adopts the following technical solutions: a globe, including a support frame and a sphere, the north and south poles of the sphere are rotatably connected to the support frame, and an angle-adjustable morning and evening plate is arranged inside the sphere, and the morning and evening plate A light source is provided in the sphere on one side, and the sphere can rotate relative to the morning and evening board and the light source. The support frame is also provided with a time ring, which is fixed outside the equatorial surface of the sphere, and is concentric and coplanar with the equatorial surface of the sphere. A time scale is set on the time ring. In this way, the globe can display the change of day and night, and help the audience to intuitively observe the sunrise and sunset times in various regions of the world, filling the gap in the market.

Description

technical field [0001] The invention relates to the field of teaching display appliances, in particular to a globe. Background technique [0002] In the process of students learning geography, the globe plays a very good display role. The globe can generally display the geographical division of the earth and geographical knowledge such as latitude and longitude, ocean currents, and wind direction through the patterns covered on the sphere. Due to the deflection of the earth's axis, the change of the rising and setting time of the sun caused by the changing seasons of the earth can also be realized through the simulation of the globe. In order to better demonstrate this change, many products have done research on the day and night demonstration function of the globe with try. [0003] For example, the patent with the publication number "CN201359810Y" and the title "Globe Displaying Day and Night" discloses a method of simulating day and night in a translucent globe shell, us...

AI Technical Summary

Problems solved by technology

When pulling the adjustment part, the power is not easy to control, it is easy to pull over the head, and it is not easy to adjust the morning and evening board to the target position, which affects the efficiency of the demonstration

[0005] In addition to the above-mentioned problems, in practical applications, it is often necessary to judge the time of sunrise and sunset through the change of the sun's irradiation angle, and there is still a market for this kind of globe that can display day and night more efficiently and help observe the time of sunrise and sunset big blank
