Globe

Abstract

The invention relates to the field of teaching display tools, in particular to a globe. In geography teaching, sunrise and sunset time often needs to be judged through season changes, and an auxiliaryteaching aid capable of displaying day and night and helping students to observe the sunrise and sunset time is needed. In order to solve the above problem, the invention adopts the following technical scheme: a globe comprises a supporting frame and a sphere, the south pole and the north pole of the sphere are rotationally connected to the support frame, an angle-adjustable terminator plate is arranged on the inner side of the sphere, a light source is arranged in the sphere on one side of the terminator plate, the sphere can rotate relative to the terminator plate and a light source, a timering is further arranged on the supporting frame, the time ring is fixedly arranged on the outer side of the equatorial plane of the sphere and is concentric and coplanar with the equatorial plane ofthe sphere, and time scales are arranged on the time ring. In this way, the globe can display day and night changes and help audiences to visually observe sunrise and sunset time of all regions in the world, and the market vacancy is filled up.

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
