Abstract
A magnetic floating rotating plate on dining-table belongs to the art field of daily necessities. Two magnets are separately arranged on a rotary plate shaft and a base. The shaft and the base are arranged together in the way of homopolar magnetic poles repulsion. The homopolar magnetic poles close to each other mutually repulse and the distance between two homopolar magnetic poles can be adjusted to make repulsive force equal to or slightly less than gravity. Then the rotary plate is in the state of weightlessness or near weightlessness, making the rotary plate float in air or nearly float, thus the rotary plate is light and flexible to be rotated. The utility model also has the advantages of simple structure and easy realization, and is especially suitable to be used as rotating plate on dining-table in catering trade.

The specific embodiment
Now operation principle of the present utility model is described by drawings and Examples.
Embodiment
Present embodiment has structure shown in Figure 1, and the main technical parameter of part is in addition enumerated as follows:
Disk 10 is circular flat planks, and diameter is 600mm.
Base plate 20 is circular flat planks, and diameter is 180mm.
First magnet 12 is identical with second magnet 22, is the annular magnet of tearing open from 12 o'clock dynamic loudspeakers, their external diameter, internal diameter and highly be respectively 135mm, 50mm and 30mm.
First magnet 12 is glued together with mode and the disk 10 that its central shaft overlaps with the central shaft of rotating shaft 11.
Second magnet 22 is glued together with mode and the base plate 20 that the central shaft of rotating shaft cover 21 overlaps with its central shaft.
The height of first roller 31 is 65mm, and roller adds up to 4, and the height of other roller is 65mm, 4 rollers with on the edge that is evenly distributed on base plate 20, rubber tire upwards is fixed on the base plate 20 with the rubber tire mode parallel with the edge of base plate 20.
Mode and base plate 20 that rotating disk 1 can rotate in shaft hole 24 with rotating shaft 11 insertion shaft holes 24 and rotating shaft 11 link together.The external diameter of rotating shaft cover 21 is 30mm, and the slightly larger in diameter of shaft hole 24 is in 15mm, and the diameter of rotating shaft 11 is 15mm, guarantees that rotating shaft 11 can insert shaft hole 24, and rotates therein.
Operation principle.
Be example now, it is described with embodiment.During use, earlier base 2 is placed on the central authorities of dining table, again shaft hole 24 is inserted in rotating shaft 11, rotating disk 1 is installed on the base 2.At this moment, present embodiment, the magnetic suspension Lazy Susan installs, can use.
On disk 10, do not put the dish dish, when promptly unloaded, the repulsion of second magnet, 22 effects, first magnet 12 thereon that rotating disk 1 is subjected to and the gravity equal and opposite in direction that rotating disk 1 is subjected to, direction is opposite, just in time offsets fully, and promptly acting on making a concerted effort on the rotating disk 1 is 0.Because rotating disk 1 is in state of weightlessness in this case, any one in 10 pairs of 4 rollers of disk all do not have pressure, so that disk 10 rotates is both light and handy, flexible again.
When being placed with the dish dish on the disk 10, the gravity that the repulsion of second magnet, 22 effects, first magnet 12 thereon that rotating disk 1 is subjected to is subjected to less than rotating disk 1.Because rotating disk 1 is in the part state of weightlessness in this case, the pressure of 10 pairs of 4 rollers of disk only be the weight of dish dish, thus disk 10 rotate still can accomplish flexibly light and handy, just so light and handy flexible when unloaded.
In addition, do not contain rolling bearing between rotating disk 1 and the base 2, therefore whether the shortcoming that present embodiment does not have rolling bearing to cause, no matter present embodiment is new, old, and be placed with the dish dish on the disk 10, and disk 10 total energy rotations are flexibly light and handy.
The utility model is particularly suitable for using on the dining table of catering trade, as Lazy Susan.
