Lunar phase teaching instrument

Abstract

The invention relates to a lunar phase teaching instrument in the field of a teaching instrument. A support plate is connected above a rotating assembly; the support plate is arranged in a way of being vertical to the rotating assembly; the support plate is arranged in a way of being parallel to a base; the support plate is arranged in a circular disc shape; a driving assembly is arranged in the center of the support plate; the driving assembly is directly connected with a driving connecting rod; the driving connecting rod is arranged on the support plate through rolling wheels; the driving connecting rod is arranged in a way of being parallel to the support plate; head end of the driving connecting rod is arranged in a way of being matched with the driving assembly; the tail end of the driving connecting rod is provided with a fixing seat; a moon model assembly is arranged on the fixing seat; and a camera assembly is arranged at one side of the support plate in a way of correspondingto a moon model, and is directly connected with a display. The periodic continuous change of the lunar phase can be directly shown through video projection; meanwhile, a teaching instruction which isstable and reliable in use is provided; the long-time repeated operation by students is convenient; clear impression is left for students; and the teaching efficiency is improved.

Description

Technical field [0001] The invention relates to a moon phase teaching instrument in the field of teaching instruments. Background technique [0002] In order to cooperate with the study of moon phase knowledge, the textbook provides a flat picture of the moon phase change in order to better understand and grasp the cause of the moon phase and the law of the moon phase change, but it is relatively abstract and difficult to understand, and the textbook does not have a supporting demonstration Teaching aids, many self-made teaching aids are used to simulate and observe the changes of the moon phases through operation, so that some students with poor sense of space are always confused about the changes; in the prior art, application number 201220688290.X, application date 2012.12.14, Authorization announcement number CN203085065 U, a moon phase change projection demonstration instrument on the authorization announcement date 2013.07.24, which includes a support frame, a motor, a hori...

[0002] In order to cooperate with the study of moon phase knowledge and better understand and master the causes of the moon phase and the law of the moon phase change, the textbook provides a plane picture of the moon phase change, but it is relatively abstract and difficult to understand, and the textbook does not have a supporting demonstration Teaching aids, many self-made teaching aids, observe the changes of the moon phase through the operation simulation, so that some students with poor sense of space are always confused about the change law; in the prior art, the application number is 201220688290.X, and the application date is 2012.12.14, Authorized announcement number CN203085065 U, a moon phase change projection demonstrator with authorized announcement date 2013.07.24, which includes a support frame, a motor, a horizontal plate, a camera, a display, a weighted ball and a weighted plate, the motor It is set in the middle of the upper end of the support frame and the output end of the motor is vertically upward. One side of the bottom end of the horizontal plate is vertically and fixedly connected with the output end of the motor. The plate, the eccentric ball and the eccentric plate are placed on the horizontal plate through a swing rod interspersed in the middle of the two. A small hole for placing the swing rod is arranged on the horizontal plate, and the camera is connected to the display; The drive is unstable and prone to jitter; it cannot provide good teaching quality
