Description

Technical Field

[0002] Dining table turntables have been widely used in restaurants and hotels and are gradually being used in family gatherings. Currently, most of the dining table turntables on the market are connected to the base using rolling bearings to achieve rotation. However, if the dishes are not evenly placed, causing excessive force on one side of the turntable, it is easy to cause the turntable to tip over. After long-term use, due to the wear of the rolling bearings, the rotation of the turntable becomes inflexible, resulting in a gradual increase in friction, and the turntable becomes increasingly inflexible or even unable to rotate, thus requiring replacement, increasing costs. This problem urgently needs to be solved. Summary of the Invention

[0016] Compared with the prior art, the embodiments of the present invention have at least the following advantages or beneficial effects:

[0017] In a first aspect, a magnetic levitation turntable includes a levitating turntable and a support disk. The levitating turntable is disposed above the support disk. A first annular magnet is provided at the upper end of the support disk, and a second annular magnet is provided at the lower end of the levitating turntable. The inner diameters of the first annular magnet and the second annular magnet are the same, and the poles of the ends close to each other are opposite; an annular limiting plate is provided on the levitating turntable, and an upper limiting assembly and a lower limiting assembly are provided on the support disk. The annular limiting plate is located between the upper limiting assembly and the lower limiting assembly, and the upper end of the lower limiting assembly is located above the first annular magnet.

[0018] Due to the repulsive force between the first annular magnet and the second annular magnet, the levitating turntable and the support disk are separated, so that the levitating turntable does not need to contact the support disk when rotating, resulting in very little friction between them, which is convenient for the user to drive, and the service life of the turntable is also longer; when the sum of the gravity of the levitating turntable and the gravity of the object placed thereon is less than the repulsive force between the first annular magnet and the second annular magnet, due to the limiting effect of the upper limiting assembly, the annular limiting plate contacts the upper limiting assembly and will not continue to rise, so that the levitating turntable will not move too far away from the support disk, and the height of the levitating turntable will not rise too high, which is convenient for the user to use. The height of the levitating turntable will be limited and will not affect the use inside the user, and the rotation is stable; when the sum of the gravity of the levitating turntable and the gravity of the object placed thereon is greater than the repulsive force between the first annular magnet and the second annular magnet, due to the limiting effect of the lower limiting assembly, and the upper end of the lower limiting assembly is located above the first annular magnet, the annular limiting plate contacts the lower limiting assembly and will not continue to descend, and the levitating turntable and the support disk will not contact, so that the friction between the levitating turntable and the support disk will not be increased excessively. Therefore, when the levitating turntable rotates, the rotation will still be more relaxed and stable.

[0019] In a second aspect, a dining table includes a dining table panel, a dining table turntable panel and a magnetic levitation turntable. The dining table turntable panel, the magnetic levitation turntable and the dining table panel are arranged in sequence from top to bottom.

The magnetic levitation turntable is placed at the upper end of the dining table panel, and the dining table turntable panel is placed at the upper end of the magnetic levitation turntable. When the dining table turntable panel rotates, due to the gravity of the dining table turntable panel, the levitating turntable will be driven to rotate. Due to the repulsive force between the first annular magnet and the second annular magnet, the levitating turntable levitates in the air, so that the friction between the dining table turntable panel and the dining table panel is very small, and the dining table turntable panel rotates more easily and stably with a longer service life.

[0029] It should be noted that: similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations. Embodiment 1

[0034] As Figures 1-3 shown, this embodiment provides a magnetic levitation turntable, including a levitation turntable 2 and a support disk 1. The above levitation turntable 2 is arranged above the above support disk 1. The upper end of the above support disk 1 is provided with a first annular magnet 3, and the lower end of the above levitation turntable 2 is provided with a second annular magnet 4. The inner diameters of the above first annular magnet 3 and the above second annular magnet 4 are the same and the poles of the ends close to each other are opposite; an annular limit plate 5 is provided on the above levitation turntable 2, and an upper limit component and a lower limit component are provided on the above support disk 1. The above annular limit plate 5 is located between the above upper limit component and the above lower limit component, and the upper end of the above lower limit component is located above the above first annular magnet 3.

[0035] In this embodiment, through the repulsive force between the first annular magnet 3 and the second annular magnet 4, the floating turntable 2 is separated from the support plate 1. Thus, when the floating turntable 2 rotates, it does not need to contact the support plate 1, resulting in very little friction between them, which facilitates the user to drive, and the service life of the turntable is also longer. When the sum of the gravity of the floating turntable 2 and the gravity of the object placed on it is less than the repulsive force between the first annular magnet 3 and the second annular magnet 4, due to the limiting effect of the upper limiting component, the annular limiting plate 5 contacts the upper limiting component and will not continue to rise. Therefore, the floating turntable 2 will not move too far away from the support plate 1, and the height of the floating turntable 2 will not rise too high, which is convenient for the user to use. The height of the floating turntable 2 will be limited and will not affect the use inside the user, and the rotation is stable. When the sum of the gravity of the floating turntable 2 and the gravity of the object placed on it is greater than the repulsive force between the first annular magnet 3 and the second annular magnet 4, due to the limiting effect of the lower limiting component, and the upper end of the lower limiting component is located above the first annular magnet 3, the annular limiting plate 5 contacts the lower limiting component and will not continue to descend. The floating turntable 2 and the support plate 1 will not contact, so that the friction between the floating turntable 2 and the support plate 1 will not be increased excessively. Therefore, when the floating turntable 2 rotates, the rotation will still be more relaxed and stable. Embodiment 2

[0036] As Figures 1-3 shown, on the basis of Embodiment 1, the lower limiting component includes a plurality of first rotating devices 6, and the plurality of first rotating devices 6 are circumferentially arranged on the support plate 1; when the annular limiting plate 5 moves downward and contacts the first rotating device 6, the annular limiting plate 5 is rotatably connected to the first rotating device 6.

[0037] In this embodiment, when the sum of the gravity of the floating turntable 2 and the gravity of the object placed on it is greater than the repulsive force between the first annular magnet 3 and the second annular magnet 4, when the annular limiting plate 5 moves downward and contacts the first rotating device 6, the annular limiting plate 5 is rotatably connected to the first rotating device 6. After the floating turntable 2 descends to the lowest position, when the floating turntable 2 rotates, the friction between the annular limiting plate 5 and the first rotating device 6 is rolling friction, making the friction between the floating turntable 2 and the first rotating device 6 very small. Thus, the rotation of the floating turntable 2 will still be very easy. Moreover, the plurality of first rotating devices 6 are annularly arranged on the support plate 1, which also has a certain guiding effect on the rotation of the floating turntable 2, making the rotation more stable and the service life longer.

[0038] In some embodiments of this embodiment, any one of the first rotating devices 6 includes a first bearing 61 and a first rotating shaft 62. One end of the first rotating shaft 62 is fixedly connected to the support plate 1, and the other end of the first rotating shaft 62 is rotatably connected to the first bearing 61.

[0039] In the above embodiments, the first bearing 61 rotates around the first rotating shaft 62, and its own friction is smaller. As a result, the friction between the floating turntable 2 and the first bearing 61 is also smaller, so that the floating turntable 2 rotates more smoothly and easily. Embodiment 3

[0040] As Figures 1-3 shown, on the basis of some of the above embodiments, the upper limit component includes a plurality of second rotating devices 7, and the plurality of second rotating devices 7 are arranged circumferentially on the floating turntable 2; when the annular limiting plate 5 moves upward and contacts the second rotating device 7, the annular limiting plate 5 is rotatably connected to the second rotating device 7.

[0041] In this embodiment, when the sum of the gravity of the floating turntable 2 and the gravity of the object placed thereon is less than the repulsive force between the first annular magnet 3 and the second annular magnet 4, when the annular limiting plate 5 moves upward and contacts the second rotating device 7, the annular limiting plate 5 is rotatably connected to the second rotating device 7. After the floating turntable 2 rises to the highest position, the floating turntable 2 rotates, and the friction between the annular limiting plate 5 and the second rotating device 7 is rolling friction, so that the friction between the floating turntable 2 and the second rotating device 7 is very small, so that the rotation of the floating turntable 2 is still very easy. Moreover, the plurality of second rotating devices 7 are arranged annularly on the support plate 1, which also has a certain guiding effect on the rotation of the floating turntable 2, making the rotation more stable and the service life longer.

[0042] In some embodiments of this embodiment, any one of the second rotating devices 7 includes a second bearing 71 and a second rotating shaft 72. One end of the second rotating shaft 72 is fixedly connected to the support plate 1, and the other end of the second rotating shaft 72 is rotatably connected to the second bearing 71.

[0043] In the above embodiments, when the second bearing 71 rotates, its own friction is smaller. As a result, the friction between the floating turntable 2 and the second bearing 71 is also smaller, so that the floating turntable 2 rotates more smoothly and easily. Embodiment 4

[0044] As Figures 1-3 shown, on the basis of some of the above embodiments, the upper end of the support plate 1 is provided with a first annular guide groove 8, the lower end of the floating turntable 2 is provided with a guide wheel 9, the guide wheel 9 is arranged in the first annular guide groove 8, and the guide wheel 9 contacts the inner wall of the guide groove.

[0045] In this embodiment, the guide wheel 9 is arranged in the first annular guide groove 8. When the floating turntable 2 rotates, it drives the guide wheel 9 to roll in the first annular guide groove 8, which can perform circumferential limit on the floating turntable 2, so that the floating turntable 2 can rotate stably in the circumferential direction, making the rotation of the floating turntable 2 smoother and more stable.

[0046] Specifically, both the above-mentioned floating turntable 2 and the support disc 1 are annular structures. The first annular guide groove 8 is located on the outer peripheral side of the first annular magnet 3. And the above-mentioned support disc 1 is provided with a second annular guide groove 10. The inner peripheral wall and the outer peripheral wall of the above-mentioned support disc 1 are respectively provided with an inner annular plate 11 and an outer annular plate 12. A plurality of the above-mentioned first rotating shafts 62 are all arranged on the side wall of the second annular guide groove 10, and a plurality of the above-mentioned second rotating shafts 72 are arranged on the outer wall of the above-mentioned inner annular plate 11. A first dust-proof strip 13 is arranged on the annular limiting plate 5, and a second dust-proof strip 14 is arranged on the outer side wall of the above-mentioned floating turntable 2. Both the above-mentioned first dust-proof strip 13 and the above-mentioned second dust-proof strip 14 are annular structures; the first dust-proof strip 13 is used to seal the gap between the annular limiting plate 5 and the inner annular plate 11, and the second dust-proof strip 14 is used to seal the gap between the floating turntable 2 and the outer annular plate 12, preventing dust from entering the gap between the floating turntable 2 and the support disc 1, so as to avoid dust adhering to the first annular magnet 3 and the second annular magnet 4, thereby affecting the repulsive force between the first annular magnet 3 and the second annular magnet 4, and thus affecting the normal use of the magnetic levitation turntable 2. Embodiment 5

[0047] As Figures 1-3 shown, on the basis of the above-mentioned some embodiments, a first installation groove is arranged at the upper end of the above-mentioned support disc 1, and the above-mentioned first annular magnet 3 is arranged in the above-mentioned first installation groove; a second installation groove is arranged at the lower end of the above-mentioned floating turntable 2, and the above-mentioned second annular magnet 4 is arranged in the above-mentioned second installation groove.

[0048] In this embodiment, the first annular magnet 3 is arranged in the first installation groove, and the second annular magnet 4 is arranged in the second installation groove, which further protects the first annular magnet 3 and the second annular magnet 4 from being damaged by external objects, making the service life of the first annular magnet 3 and the second annular magnet 4 longer. Embodiment 6

[0049] As Figures 1-3 shown, on the basis of the above-mentioned some embodiments, the above-mentioned first annular magnet 3 includes a plurality of third magnets 31. A plurality of first partition plates are arranged in the above-mentioned first installation groove, and the plurality of the above-mentioned first partition plates divide the above-mentioned first installation groove into a plurality of third installation grooves, and the above-mentioned third magnets 31 are arranged in the above-mentioned third installation grooves; the above-mentioned second annular magnet 4 includes a plurality of fourth magnets 41. A plurality of second partition plates are arranged in the above-mentioned second installation groove, and the plurality of the above-mentioned second partition plates divide the above-mentioned second installation groove into a plurality of fourth installation grooves, and the above-mentioned fourth magnets 41 are arranged in the above-mentioned fourth installation grooves.

[0050] In this embodiment, the first annular magnet 3 is divided into a plurality of small third magnets 31. The third magnets 31 can be approximately rectangular, which is easier to manufacture compared to the annular first annular magnet 3. Thus, the manufacture of the entire first annular magnet 3 formed is also easier. Moreover, the plurality of third magnets 31 are respectively placed in corresponding third installation grooves, so that the third magnets 31 are protected accordingly. And if the magnetism of one third magnet 31 decreases, it can be replaced without replacing all of them, reducing the replacement cost. The second annular magnet 4 is divided into a plurality of small fourth magnets 41, making the fourth magnets approximately rectangular, which is easier to manufacture compared to the annular second annular magnet 4. Thus, the manufacture of the entire second annular magnet 4 formed is also easier. Also, the plurality of fourth magnets 41 are respectively placed in corresponding fourth installation grooves, so that the fourth magnets 41 are protected accordingly. And if the magnetism of one fourth magnet 41 decreases, it can be replaced without replacing all of them, reducing the replacement cost. Embodiment 7

[0051] As Figure 4 shown, based on some of the above embodiments, a dining table in this embodiment includes a dining table panel 16, a dining table turntable panel 15, and a magnetic levitation turntable 2. The above-mentioned dining table turntable panel 15, the above-mentioned magnetic levitation turntable 2, and the dining table panel 16 are arranged in sequence from top to bottom.

[0052] In this embodiment, the dining table turntable panel 15, the magnetic levitation turntable 2, and the dining table panel 16 are arranged in sequence from top to bottom. The magnetic levitation turntable 2 is placed at the upper end of the dining table panel 16, and the dining table turntable panel 15 is placed at the upper end of the magnetic levitation turntable 2. When the dining table turntable panel 15 rotates, due to the gravity of the dining table turntable panel 15, it will drive the suspension turntable 2 to rotate. Due to the repulsive force between the first annular magnet 3 and the second annular magnet 4, the suspension turntable 2 floats in the air. Thus, the friction between the dining table turntable panel 15 and the dining table panel 16 is very small, so that the dining table turntable panel 15 rotates more easily and stably, and has a longer service life.

[0053] In some implementation manners of this embodiment, a plurality of first support cylinders 17 are provided at the lower end of the above-mentioned support disk 1, and the above-mentioned dining table panel 16 is arranged at the lower ends of the plurality of above-mentioned first support cylinders 17; a plurality of second support cylinders 18 are provided at the upper end of the above-mentioned suspension turntable 2, and the above-mentioned dining table turntable panel 15 is arranged at the upper ends of the plurality of above-mentioned second support cylinders 18.

[0054] In the above-described embodiments, a plurality of first support cylinders 17 are provided between the support plate 1 and the tabletop panel 16. On the one hand, it is convenient to take the support plate 1, and on the other hand, the friction between the support plate 1 and the tabletop panel 16 is reduced, thereby avoiding damage to the entire panel of the tabletop panel 16 after long-term use; a plurality of second support cylinders 18 are provided between the floating turntable 2 and the table turntable panel 15. On the one hand, it is convenient to take the table turntable panel 15, and on the other hand, the friction between the table turntable panel 15 and the floating turntable 2 is reduced, thereby avoiding damage to the entire panel of the table turntable panel 15 after long-term use.

[0055] In summary, the embodiment of the present invention provides a magnetic levitation turntable, including a floating turntable 2 and a support plate 1. The floating turntable 2 is disposed above the support plate 1. A first annular magnet 3 is provided at the upper end of the support plate 1. A second annular magnet 4 is disposed at the lower end of the floating turntable 2. The inner diameters of the first annular magnet 3 and the second annular magnet 4 are the same and the poles of the adjacent ends are opposite; an annular limiting plate 5 is provided on the floating turntable 2. An upper limiting component and a lower limiting component are provided on the support plate 1. The annular limiting plate 5 is located between the upper limiting component and the lower limiting component, and the upper end of the lower limiting component is located above the first annular magnet 3.

[0056] Through the repulsive force between the first annular magnet 3 and the second annular magnet 4, the floating turntable 2 and the support plate 1 are separated, so that the floating turntable 2 does not need to contact the support plate 1 when rotating, and the friction between them is very small, thus facilitating the user to drive, and the service life of the turntable is also longer; when the sum of the gravity of the floating turntable 2 and the gravity of the objects placed thereon is less than the repulsive force between the first annular magnet 3 and the second annular magnet 4, due to the limiting effect of the upper limiting component, the annular limiting plate 5 contacts the upper limiting component and will not continue to rise, so that the floating turntable 2 will not be too far away from the support plate 1, and the height of the floating turntable 2 will not rise too high, which is convenient for the user to use. The height of the floating turntable 2 will be limited and will not affect the use inside the user, and the rotation is stable; when the sum of the gravity of the floating turntable 2 and the gravity of the objects placed thereon is greater than the repulsive force between the first annular magnet 3 and the second annular magnet 4, due to the limiting effect of the lower limiting component, and the upper end of the lower limiting component is located above the first annular magnet 3, the annular limiting plate 5 contacts the lower limiting component and will not continue to descend, and the floating turntable 2 and the support plate 1 will not contact, so that the friction between the floating turntable 2 and the support plate 1 will not be increased excessively. Therefore, when the floating turntable 2 rotates, the rotation will still be more relaxed and stable.

[0057] A table includes a tabletop panel 16, a table turntable panel 15 and a magnetic levitation turntable 2. The table turntable panel 15, the magnetic levitation turntable 2 and the tabletop panel 16 are arranged in sequence from top to bottom.

[0058] The tabletop turntable panel 15, the maglev turntable 2, and the tabletop panel 16 are arranged from top to bottom in sequence. The maglev turntable 2 is placed at the upper end of the tabletop panel 16, and the tabletop turntable panel 15 is placed at the upper end of the maglev turntable 2. When the tabletop turntable panel 15 rotates, due to the gravity of the tabletop turntable panel 15, it will drive the floating turntable 2 to rotate. Due to the repulsive force between the first annular magnet 3 and the second annular magnet 4, the floating turntable 2 floats in the air. Thus, the frictional force between the tabletop turntable panel 15 and the tabletop panel 16 is very small, so that the tabletop turntable panel 15 rotates more easily and stably and has a longer service life.

[0059] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, various changes and modifications can be made to the present invention.
