Embodiment 1

[0033] Such as figure 1 As shown, a magnetic levitation display device includes a globe 1 , a base 2 , and a display stand 3 above the base 2 . A groove 4 is provided on the display base 3 , and the globe 1 is embedded in the groove 4 and ball-connected to the groove 4 . A conical groove 5 arranged coaxially with the globe 1 is opened in the base 2 . The inner wall of the conical groove 5 is provided with a first magnetic piece 6, and the angle between the first magnetic piece 6 and the central axis of the globe 1 is α, and α is an acute angle. There are several first magnetic parts 6 around the central axis of the globe 1, and the number of the first magnetic parts 6 is an even number. The bottom surface of the display base 3 is provided with a second magnetic member 7, and several second magnetic members 7 are arranged around the central axis of the globe 1 in the circumferential direction. Each second magnetic piece 7 corresponds to a first magnetic piece 6 and the secon...

Embodiment 2

[0036] The difference between the second embodiment and the first embodiment is that, in order to make the device suspend more globes 1 of various weights, it is necessary to make the first magnetic part 6 move along the vertical direction with the display stand 3 along the longitudinal direction of the first magnetic part 6. Movement, so that the projection of the first magnetic part 6 along its thickness direction coincides with the second magnetic part 7, so that the repulsive force that can be generated between the first magnetic part 6 and the second magnetic part 7 is maximized.

[0037] Such as figure 2 As shown, specifically, the inner wall of the conical groove 5 is provided with a sliding groove 8 along the length direction of the first magnetic member 6 , and the first magnetic member 6 is embedded in the sliding groove 8 and is slidably connected to the sliding groove 8 . A follower assembly 9 is provided between the base 2 and the display seat 3 , and the followe...

Abstract

The invention discloses a magnetic levitation display apparatus. The magnetic levitation display apparatus comprises a base and a display seat located on the base and used for placing a globe, the display seat is provided with a groove used for embedding the globe, a tapered groove is arranged in the base, an inner wall of the tapered groove is provided with first magnetic parts, included angles between the first magnetic parts and the central axis of the globe are acute angles, a plurality of an even number of first magnetic parts are arranged in the circumferential direction around the central axis of the globe, the bottom surface of the display seat is provided with second magnetic parts, a plurality of second magnetic parts are arranged in the circumferential direction around the central axis of the globe, and each second magnetic part corresponds to one first magnetic part and is parallel to the first magnetic part. Repulsive forces between the first magnetic parts and second magnetic parts are upwardly inclined relative to the globe, two opposite repulsive forces can mutually offset the forces to the globe in the horizontal directions thereof, the gravity of the globe and thedisplay seat can be balanced by the forces to the globe along the vertical directions of the repulsive forces, and the globe is arranged above the base in a suspension manner. According to the apparatus, the globe can be rotated relative to the display seat, each direction of the globe can be observed, and the practicality is high.

Description

technical field [0001] The invention relates to a magnetic levitation instrument, in particular to a magnetic levitation display device. Background technique [0002] In order to facilitate the understanding of the earth, people imitate the shape of the earth, shrink it according to a certain ratio, and make a model of the earth, that is, a globe. In addition, in order to facilitate teaching and use, a rotating shaft is usually installed on the globe to rotate, so as to facilitate the observation of the globe. [0003] Ordinary globes can only rotate around the axis, but cannot be flipped, and the pattern on the bottom of the globe is difficult to observe, which is poor in practicability and needs to be improved. Contents of the invention [0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a magnetic levitation display device, the globe using the device can observe various angles of the globe, and has strong practicabi...
