Description

Technical Field

[0001] The utility model relates to the technical field of three-ball instruments, in particular to a multifunctional three-ball instrument. Background Art

[0002] The three-sphere instrument, also known as the lunar-terrestrial orbiter, is an instrument for astronomy teaching and popularization. It consists of three small balls representing the sun, the earth and the moon, and has a mechanical linkage device to demonstrate the relationship between the three balls and some astronomical phenomena resulting from it.

[0003] After searching, the existing Chinese patent with publication number CN202222918879.0 discloses a geography teaching aid for demonstrating the relationship between the movement of three balls. The device can be disassembled and installed through the mutual cooperation among the base plate, the handle, the plug rod, the ball screw, the first telescopic spring, the first screw nut, the second screw nut, the movable disk, the first groove, the second groove, the third telescopic spring, the splint and the second rotating motor, which can make the device more convenient to carry. The mutual cooperation among the gear ring, the simulated earth, the first rotating motor, the simulated moon, the rotating rod, the simulated sun, the gear, the connecting rod, the fixed rod and the second rotating motor can allow students to intuitively observe the changes in the movement between the sun, the earth and the moon, so as to help students have a deeper understanding of the changes in nature.

[0004] The above technical solution has the following defects: although such a three-ball instrument can drive the moon model, the earth model and the sun model through a motor and gears to simulate the movement between the sun, the earth and the moon, in actual use, the small three-ball instrument is usually used for teaching in geography classes. It is easy to be polluted by dust when placed on weekdays, and it is inconvenient for students under the classroom to watch it if it is only placed on the desk. In order to facilitate display in public places such as classrooms, a multifunctional three-ball instrument is proposed, which can simulate the movement between the sun, the earth and the moon through a motor drive, and the display height and display angle can be adjusted according to needs, so that the three-ball instrument is easy to display and easy to store for safe storage.

[0005] In view of this, the author improves and solves the above problems, concentrates on research and cooperates with theoretical application, and finally proposes a technical solution with reasonable design and effective improvement of the above defects.

[0006] The information disclosed in this background technology section is only intended to deepen the understanding of the overall background technology of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to those skilled in the art.
