Description

Technical Field

[0001] This utility model belongs to the field of rotating dining tables, and in particular relates to a rotating dining table with high load-bearing capacity. Background Technology

[0002] Existing rotating dining tables, such as the electric rotating round dining table in application number 201410388929.6, include a circular tabletop with multiple support legs at the bottom and a turntable on the upper side of the tabletop. A flat bearing is provided between the tabletop and the turntable, and the turntable can rotate freely.

[0003] In some upscale restaurants, tabletops and turntables are usually made of solid wood. Due to frequent and prolonged use, and the large amount of food placed on the turntable for extended periods, the turntable is under heavy load. The turntable is supported by a flat bearing, and the flat bearings used to support the turntable are generally small in size, with a small support range, making them prone to deformation. Similarly, the weight of the tabletop is entirely applied to the tabletop, and the stress area on the tabletop is the installation location of the flat bearing. The stress area is small, making it relatively easy to deform. Utility Model Content

[0004] The purpose of this invention is to provide a rotating dining table with high load-bearing capacity. This invention has the advantage of high load-bearing capacity.

[0005] The technical solution of this utility model is as follows: A rotating dining table with high load capacity includes a cylindrical support platform, which is axially hollow. A ring-shaped tabletop is placed on the support platform. A base is provided inside the support platform, and a bracket is rotatably connected to the base. A support ring is provided on the top of the bracket, and a turntable is placed on the support ring. The diameter of the turntable is larger than the inner diameter of the tabletop, and the outer diameter of the support ring is smaller than the inner diameter of the support platform.

[0006] In the aforementioned high-load-bearing rotating dining table, the bottom of the tabletop is provided with at least three circumferentially distributed limiting blocks, which are close to the inner sidewall of the support platform.

[0007] In the aforementioned high-load-bearing rotating dining table, the top of the base is provided with a central shaft, the upper end of which is rotatably connected to an upper flange. The upper flange is provided with a plurality of circumferentially distributed first support rods. A second support rod and a third support rod are sequentially provided above the first support rods. At least two first columns are provided between the first and second support rods. At least two screws are provided between the second and third support rods. Nuts connected to the corresponding screws are provided on the upper and lower sides of the second and third support rods. The outer end of the third support rod is fixed to the lower part of the support ring.

[0008] In the aforementioned high-load-bearing rotating dining table, a support block is provided above the upper flange, the top surface of the support block is flush with the top surface of the support ring, and the inner end of the third support rod is fixed to the bottom surface of the support block.

[0009] In the aforementioned high-load-bearing rotating dining table, the lower end of the central shaft is rotatably connected to a lower flange, a fourth support rod is provided below the first support rod, and at least two second columns are provided between the first support rod and the fourth support rod. The upper and lower ends of one of the second columns are respectively connected to the outer ends of the first support rod and the fourth support rod, and the inner end of the fourth support rod is fixed to the lower flange.

[0010] In the aforementioned high-load-bearing rotating dining table, the bottom of the base is provided with multiple circumferentially distributed fifth support rods, the outer ends of the fifth support rods extend to the outer side of the base, and the bottom of the fifth support rods is screwed with height adjustment feet.

[0011] In the aforementioned high-load-bearing rotating dining table, the inner side of the support ring is provided with at least three connecting pieces, which are connected to the turntable screws, and an inspection door is provided on the support platform.

[0012] Compared with existing technologies, the tabletop and turntable of this invention are supported by the ground separately, preventing the weight of the turntable from being transferred to the tabletop, thus reducing the tabletop's deformation and resulting in high load-bearing capacity. The turntable is the main load-bearing component, supported by a support ring and a bracket at the bottom of the support ring. The diameter of the support ring can be close to the diameter of the turntable, giving the turntable a large support range. Simultaneously, the turntable is also supported by a support block connected to the bracket in the middle, further reducing its deformation and contributing to its high load-bearing capacity. Therefore, this invention has the advantage of high load-bearing capacity.

[0013] Furthermore, by setting a screw between the second and third support rods and placing a nut on the screw, the height of the outer end of the third support rod can be finely adjusted, resulting in a high flatness of the support ring, ensuring contact between the support ring and the turntable plane, thus stabilizing the turntable and further improving its load-bearing capacity.

[0014] By installing rotatable flanges at both the upper and lower ends of the central shaft, with both flanges simultaneously connecting to the outer ends of the third support rod, the structural strength between the central shaft and the third support rod is increased. This makes the support rods and columns less prone to deformation, and the third support rod is easier to keep level, allowing for greater load capacity. Furthermore, it better prevents the turntable from tilting when the load distribution on the turntable is uneven, resulting in better performance. Attached Figure Description

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0019] Example: A high-load-bearing rotating dining table, such as Figure 1 As shown, the device includes a cylindrical support platform 1, which is axially hollow. A ring-shaped tabletop 2 is placed on the support platform 1. A base 3 is located inside the support platform 1, and a bracket is rotatably connected to the base 3. A support ring 4 is located on the top of the bracket, and a turntable 5 is placed on the support ring 4. The outer diameter of the support ring 4 is 5-15 cm smaller than the diameter of the turntable 5. The diameter of the turntable 5 is larger than the inner diameter of the tabletop 2, which is used to cover the inner hole of the tabletop 2. The outer diameter of the support ring 4 is smaller than the inner diameter of the support platform 1, allowing the turntable 5 to be close to the tabletop 2, reducing the gap between the turntable 5 and the tabletop 2, and preventing chopsticks, spoons, and other items from entering between the turntable 5 and the tabletop 2. At the same time, when the turntable 5 is removed from the support ring 4, the tabletop 2 can be moved upward away from the support platform 1, making it easier to replace the damaged tabletop 2.

[0020] The bottom of the tabletop 2 is provided with at least three circumferentially distributed limiting blocks 6, which are close to the inner sidewall of the support platform 1. The limiting blocks 6 are used to prevent the tabletop 2 from moving radially, so that the tabletop 2 and the turntable 5 remain coaxial.

[0021] A central shaft 7 is welded to the top of the base 3. The upper end of the central shaft 7 is connected to an upper flange 8 by a bearing. Six circumferentially distributed first support rods 9 are provided on the upper flange 8. The first support rods 9 are horizontally arranged, and the inner end of the first support rods 9 is connected to the upper flange 8 by screws.

[0022] Above the first support rod 9, there are a second support rod 10 and a third support rod 11 arranged in sequence. The second support rod 10 and the third support rod 11 are both horizontally arranged. There are two vertical first columns 12 between the first support rod 9 and the second support rod 10. The two first columns 12 are located at both ends of the second support rod 10, and the upper and lower ends of the columns 12 are welded and fixed to the first support rod 9 and the second support rod 10, respectively.

[0023] Two vertical screws 13 are provided between the second support rod 10 and the third support rod 11. The two screws 13 are respectively close to the two ends of the second support rod 10. Nuts 14 connected to the corresponding screws 13 are provided on the upper and lower sides of the second support rod 10 and the upper and lower sides of the third support rod 11. The outer end of the third support rod 11 is welded and fixed to the lower part of the support ring 4. By adjusting the axial position of the nuts 14 on the upper and lower sides of the third support rod 11 on the screws 13, the height of a local area of ​​the support ring 4 can be changed, thereby achieving the leveling of the entire support ring 4, eliminating the gap between the support ring 4 and the turntable 5, and forming a uniform gap between the turntable 5 and the table 2. This ensures smooth rotation of the turntable 5 while maintaining a good appearance.

[0024] A support block 15 is provided above the upper flange 8. The top surface of the support block 15 is flush with the top surface of the support ring 4. The inner end of the third support rod 11 is welded and fixed to the bottom surface of the support block 15. In addition to the outer edge of the turntable 5 being supported by the support ring 4, the center of the turntable 5 is also supported by the support block 15, making the turntable 5 less prone to deformation and providing better load-bearing capacity. When the diameter of the turntable 5 is very large, such as exceeding 1.5 meters, a support block can be welded to the third support rod 11 to provide more support for the turntable 5.

[0025] The lower end of the central shaft 7 is connected to a lower flange 16 bearing. A fourth support rod 17 is provided below the first support rod 9. The fourth support rod 17 is horizontally arranged. Two second columns 18 are provided between the first support rod 9 and the fourth support rod 17. One of the second columns 18 is inclined and its lower end faces inward. Its upper and lower ends are respectively welded to the outer ends of the first support rod 9 and the outer ends of the fourth support rod 17. The other second column 18 is vertically arranged. The inner end of the fourth support rod 17 is connected to the lower flange 16 with screws.

[0026] The base 3 has six circumferentially distributed fifth support rods 19 at its bottom. The outer ends of the fifth support rods 19 extend to the outer side of the base 3, and the bottom of the fifth support rods 19 is screwed with height adjustment feet 20.

[0027] Six connecting pieces 21 are welded to the inner side of the support ring 4. The connecting pieces 21 are close to the top surface of the support ring 4. The connecting pieces 21 are thin-walled iron sheets and are screwed to the turntable 5. An inspection door 22 is provided on the support platform 1. When the inspection door 22 is opened, the screws on the connecting pieces 21 can be removed, and the turntable 5 can be moved away for easy replacement if the turntable 5 is damaged.

[0028] The base 1, table 2, and turntable 5 are exposed parts, and their materials are selected according to customer requirements. The base 3, support ring 4, central shaft 7, upper and lower flanges, support rods, and columns are made of steel.

[0029] Instructions for use: Due to extensive welding, the bracket assembly exhibits significant deformation errors after molding. Therefore, the turntable 5 needs to be kept level by adjusting the height adjustment feet 20. Similarly, because the support ring 4 is welded to each of the third support rods 11, the support ring 4 is also prone to deformation and insufficient flatness. The nuts 14 on the upper and lower sides of the third support rods 11 need to be adjusted to keep the support ring 4 flat, ensuring that the turntable 5 can contact the support ring 4 surface. This results in a high load-bearing capacity and stable placement of the turntable 5.
