Description
Technical field:
The utility model relates to the geographical teaching teaching aid, relates in particular to the two ball devices of geographical teaching.
Background technology:
Usually in the activity of geographical teaching and universal astronomical geography knowledge, the teacher in explanation because during revolution and rotation produced the various astronomical geography phenomenon of the earth, generally also can only be by terrestrial globe and other assistant teaching aid, or utilize wall chart to demonstrate and explain, the geographical teaching aid of prior art lacks intuitive undoubtedly, make the student who begins to learn be difficult to understand quickly, and the teacher also feel very difficult in the process of explanation, influence the quality of geographical teaching.
The utility model content:
The purpose of this utility model is, overcomes the deficiencies in the prior art part, provides a kind of geographical teaching with two ball devices, can demonstrate intuitively because the multiple astronomical geography phenomenon that revolution and rotation produced of the earth.
Geographical teaching described in the utility model is with two ball devices, includes magnet cross beam frame, sunlight indicator, support, astronomical globe, terrestrial globe, morning and evening ball, bearing, bent axle, rotary sleeve, bent axle fixed mount, the earth's axis and pedestal and forms.Pedestal is an earthing member of the present utility model, whole structure in the form of annular discs, in order to guarantee stability of the present utility model, pedestal adopts cast iron materials to make, the top middle position of pedestal is provided with the pedestal central support shaft, in the top of pedestal central support shaft one side, be provided with and be 1/4th spherical supports, the upper end of support is connected with the sunlight indicator.One side of the pedestal central support shaft that makes progress at support is provided with the bent axle fixed mount, and the inboard, upper end at the bent axle fixed mount is provided with rotary sleeve, and rotary sleeve is arranged on the oblique axis identical with the earth's axis, is provided with bent axle above the rotary sleeve.The upper end of bent axle is provided with the connecting lever axle, the connecting lever axle by bearing with morning and evening ball be connected.The upper end of pedestal central support shaft is connected with astronomical globe, and the upper end of bent axle then is connected to the ball in morning and evening, between morning and evening ball and astronomical globe, is provided with terrestrial globe, morning and evening ball the middle position, be provided with the magnet cross beam frame of horizontal versions.
The two ball devices of geographical teaching described in the utility model, one-piece construction is simple, and is easy for operation, good stability, the reliability height can be demonstrated intuitively because the multiple astronomical geography phenomenon that revolution and rotation produced of the earth.
