The utility model can be used as a teaching instrument as well as a high-grade ornament placed on a office desk by people. The utility model can bring on more abundant mind's eye of people.

Description

Globe dynamically

Technical field

The utility model relates to a kind of dynamically globe that can show the sun and earth running orbit.

Background technology

At present, the terrestrial globe that is used for all kinds of numerals, various in style, but function singleness, can not dynamically express the spinning motion and the sun tropic position on earth of the earth, and daytime half a year of figurative expression earth south poles, spontaneous phenomenons such as night half a year, Chinese patent 00233711.8 discloses " a kind of new type electro terrestrial globe ", under the situation that it can solve in the dark or light is dark, also can watch the problem of terrestrial globe, Chinese patent 02273417.1 discloses a kind of " globe clock ", it can make people understand tilt rotation and revolution and spring, summer, autumn and winter 24 solar term rules of the earth, various places time and circadian variation, these terrestrial globes can only be used to watch statically, can not dynamically turn round automatically.

Summary of the invention

The purpose of this utility model just provides a kind of dynamically globe, can show the sun and earth running orbit truly, reacts the sun tropic and terminator on earth truly, figurative expression earth south poles daytime half a year, spontaneous phenomenons such as night half a year.

The utility model is achieved like this, it comprises transparent spherical shell, support, bearing, motor, rotating shaft, driven wheel, bevel type gear, bent axle, connecting rod, balance iron, shadow shield, laser lamp, bulb, bearing connects support, support is connected the inboard of transparent spherical shell, be connected with motor on the support, motor connects rotating shaft by gear, the lower end of rotating shaft connects driven wheel, and driven wheel connects follower gear, and follower gear is connected on the bearing, the upper end of rotating shaft connects bevel type gear, bevel type gear connects small transmission gear by drive link, small transmission gear and big transmission gear engagement, small transmission gear turns around, and big transmission gear changes lattice, big transmission gear connects bent axle, bent axle connects connecting rod, and balance iron is connected on the bent axle, and semicircular shadow shield is connected on the support.Luminous lamp and several common bulbs are housed on support.On bearing, be connected with electric-controlled switch and attaching plug.

The utility model is installed motor in transparent spherical shell, make its rotation by gear, by mechanical driving device and light units, represent the sun and earth running orbit, people are come into plain view to the sun tropic and terminator, daytime half a year of earth south poles, the spontaneous phenomenon at night half a year on earth.Both can make instruments used for education, also can be placed on high-grade ornament on the desk, cause the more lively fancy of people as people.
