Problems solved by technology
[0002] In traditional globes, the sphere is generally set on the bracket, and the rotating shaft fixed at the two poles of the sphere is flexibly connected with the bracket to realize the rotation of the sphere to observe different geographical conditions: but in use, it is found that if you want to observe the poles carefully Due to geographical conditions, the globe needs to be reversed or tilted, making it extremely inconvenient to use

Embodiment Construction
[0008] The present invention is described in conjunction with the accompanying drawings: as shown in the accompanying drawings, a biaxial globe that can rotate 360°,
[0009] Connecting shaft 3 is put into the central hole of equatorial disk 4, and the cooperation between connecting shaft 3 and the central hole of equatorial disk 4 is rotatable with clearance. Mount northern hemisphere 1 and southern hemisphere 2 on the two ends of connecting shaft 3, and simultaneously put them After sticking tightly, the sphere can rotate about 180° on the central axis of the equatorial disk 4; Two small shafts 6, so that the equatorial disk 4 has a sphere, and the axis of the small hole in the support seat 5 can also be rotated about 180 °, so that the biaxial of the whole globe can rotate 360 ° on the support seat 5. Dual-axis globe, you can observe the geographical conditions of the entire globe more carefully.

Provided is a tellurion used for official business, teaching and entertainment. The tellurion comprises a northern hemisphere, a southern hemisphere, a connection shaft, an equatorial disc and a support base. The sphere body can leftward and rightward rotate for 180 degrees on the equatorial disc, and the sphere body can also be driven by the equatorial disc to leftward and rightward rotate for 180 degrees on the support base. Therefore, double shafts of the whole tellurion can rotate on the support base for 360 degrees, and the geographical state of the whole tellurion can be more carefully observed via the double-shaft tellurion.
Description
technical field [0001] The invention relates to a teaching instrument, in particular to a biaxial globe capable of 360° rotation. Background technique [0002] In traditional globes, the sphere is generally set on the bracket, and the rotating shaft fixed at the two poles of the sphere is flexibly connected with the bracket to realize the rotation of the sphere to observe different geographical conditions: but in use, it is found that if you want to observe the poles carefully Geographical conditions require the globe to be reversed or tilted, resulting in extremely inconvenient use. Contents of the invention [0003] The object of the present invention is to provide a 360°-rotatable biaxial globe with simple structure and convenient use. The technical solution for achieving the above purpose is: a 360°-rotatable biaxial globe, including northern hemisphere 1, southern hemisphere 2, connecting axis 3, equatorial disk 4, and support seat 5, and the northern and southern he...
