Abstract
The utility model relates to an electric rotating globe, which comprises a globe. The utility model is characterized in that the globe is connected with a mechanism which can cause the globe to rotate. The mechanism comprises an electric motor. The electric motor is connected with a driving bevel gear by a decelerator. The driving bevel gear is engaged with a driven bevel gear which is connected with a rotary shaft. The rotary shaft is provided with a straight gear which is engaged with the straight gear arranged on another rotary shaft. The rotary shaft is connected with the globe. The rotary mechanism is arranged on a frame body. Because the electric rotary mechanism is connected to the globe, the utility model can cause the globe to automatically rotate. When the globe rotates, people can carry out operation better by regulating the rotational speed, and thus the trouble of rotating the globe by hand is solved.
Description
Affiliated field
The utility model relates to a kind of terrestrial globe, and what relate to specifically is a kind of rotating terrestrial globe.
Background technology
At present the terrestrial globe model all is to be fixed on the support, be connected with dwang on the terrestrial globe, and people rotate this form by manually making terrestrial globe.Because can only lean on people's formula to rotate the globe, therefore, when imparting knowledge to students or watching, hand can often touch terrestrial globe, like this, on the one hand manually can be cumbersome, on the other hand, the long-time terrestrial globe that touches can make pattern on the terrestrial globe, that the handwriting is blurred is unclear, is difficult for identification.
Technology contents
The purpose of this utility model is in order to solve the deficiencies in the prior art part, to provide a kind of by driven by power, the automatic electric power that rotates of terrestrial globe being rotated the globe.
For achieving the goal, the utility model provides following technical solution:
A kind of electric power rotates the globe, include terrestrial globe, it is characterized in that terrestrial globe is connected with a mechanism that makes its rotation, include motor in this mechanism, motor is connected with an active oblique gear by speed reduction unit, active oblique gear meshes driven spiral gear, driven spiral gear is connected with rotation axis, and rotation axis is provided with straight-tooth, and the straight-tooth that is provided with on this spur gear and another rotation axis is connected with a joggle, rotation axis is connected with terrestrial globe, and rotating mechanism is located on the support body.
Therefore the utility model can rotate terrestrial globe owing to connected the electric power rotating mechanism on terrestrial globe automatically, and by regulating rotating speed, when terrestrial globe was rotated, people can carry out work better, thereby have solved the trouble of being brought by the hand rotation terrestrial globe.
Description of drawings
Accompanying drawing is the utility model structural representation
Embodiment
As scheme institute and ask, on the terrestrial globe ball seat, be placed with terrestrial globe 1, the terrestrial globe below is connected with a rotating mechanism, this rotating mechanism is fixed on the support, it is motor 2, speed reduction unit 3 is placed on the frame 4 it is fixed, speed reduction unit is connected with active oblique gear 5, the driven spiral gear 6 of active oblique gear 5 engagements, driven spiral gear 6 is connected with rotation axis 7, and spur gear 8 is arranged on the rotation axis 7, straight-tooth 10 on this spur gear 8 and another rotation axis 9 is connected with a joggle, rotation axis 9 is connected with terrestrial globe 1, rotation axis 7,9 two ends are connected with bearing 11, and bearing 11 is fixed on the support 12, like this, can make gear and rotation axis operate as normal.Rotation axis 9 passes bearing 11 and links to each other with terrestrial globe, and like this, rotation axis rotates, and can drive terrestrial globe and rotate.
Still can see pattern and literal it on clearly when terrestrial globe is rotated, then need to make terrestrial globe to rotate in a slower range of speeds, at this moment, can reach by the adjustment gear number of teeth.
