Abstract
The utility model relates to a tellurian, wherein, a semicircular spherical surface ranging ruler (2) is arranged between a sphere (1) and a bracket (5) of the prior tellurian. The arc distance between any two points on the surface of the sphere (1) can be accurately measured out by rotating the sphere (1) and the spherical surface ranging ruler (2), so as to calculate out the actual distance between any two places on the earth according to the proportional scale of the tellurian. Therefore, the utility model has more positive significance than the prior tellurian, which is an ideal teaching aid for geoscience.
Description
The utility model relates to a kind of novel terrestrial globe that the sphere telemeter rod is housed, and belongs to the teaching aid field.
At present, known terrestrial globe does not all have engineer's scale, does not more have the sphere distance measuring equipment, thereby the distance between the two places is determined in inconvenience.
The purpose of this utility model is that a kind of novel terrestrial globe will be provided, and it is equipped with the sphere telemeter rod, thereby can measure the arc distance of any point-to-point transmission of its spherome surface more accurately.
The purpose of this utility model is achieved in that between the spheroid and semi-circular bracket of known terrestrial globe, adorns a semicircular sphere telemeter rod.The sphere telemeter rod can rotate around the chi axle, can measure the arc distance of any point-to-point transmission of spherome surface, thereby but the engineer's scale of base area globe just calculates on the earth actual range between the two places arbitrarily.
Owing to adopt such scheme, available sphere telemeter rod measures the arc distance between any 2 of the globe sphere surface, therefore compares with known terrestrial globe, and the utility model more is rich in good effect.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural drawing of the present utility model.
Among the figure, 1. spheroid 2. sphere telemeter rods 3. chi axles 4. ball journals 5. supports 6. bases
In Fig. 1, spheroid (1) is installed in support (5) by ball journal (4) and goes up and can rotate around ball journal.The sphere telemeter rod (2) that has scale is installed between support (5) and the spheroid (1) by chi axle (3), and can rotate around chi axle (3).When measuring the arc distance of sphere point-to-point transmission, rotating sphere (1) and sphere telemeter rod (2) just can measure the arc distance of the point-to-point transmission of surveying according to the scale on the sphere telemeter rod (2) to correct position respectively.Thereby the engineer's scale of base area globe just can calculate the actual range between any two places on the earth.
