[0045] The preferred embodiments of the present invention will now be described in detail.

[0046] This invention provides a rotating ball 32 on the tabletop, which supports the turntable and facilitates its rotation. This prevents the turntable from tilting due to too much food placed on one side, thus avoiding water overflowing onto the tabletop. Additionally, a drainage channel 12 is provided on the tabletop to collect water overflowing from the turntable, preventing water from splashing onto the floor or overflowing onto the tabletop. Example

[0047] like Figures 3-5 The diagram shown is a schematic of the present invention. It is typically used to install a turntable dining table, and while driving the turntable dining table to rotate and rise stably, it also facilitates the collection of water accumulated on the turntable dining table, preventing water from splashing onto the ground or overflowing onto the tabletop (turntable dining tables are a conventional structure and are sold on Taobao, JD.com, etc.). It includes a bracket 1, foot pads 2, base plate 3, middle plate 4, top plate 5, slot 6, through groove 7, first carrier plate groove 8, first storage groove 9, second carrier plate groove 10, second storage groove 11, drainage groove 12, ball pad groove 13, frame 16, fixing frame 17, lifting cylinder 18, carrier plate 19, guide plate 20, and ball pad 27.

[0048] The support frame 1 is made of marble and primarily serves a supporting function for the table. Compared to metal, marble is rust-resistant, deformation-resistant, and has higher strength, while also being less expensive. The feet 2 are attached to the bottom of the support frame 1 using adhesive. Figure 3As shown, the foot pad 2 is in the shape of an isosceles trapezoid. The upper base of the isosceles trapezoid foot pad 2 is bonded to the bottom of the support 1 with structural adhesive, and the lower base is in contact with the ground. The shape of the isosceles trapezoid ensures that the weight distribution of the table is more balanced and that the table is placed more stably. (The material of the foot pad 2 is rubber, which has good extensibility and can play a good cushioning effect on heavy objects placed on the table.)

[0049] like Figure 6 The diagram shows the structure of the base plate 3. The base plate 3 is a circular wooden board, which is fixed to the top of the bracket 1 by screws. Figure 7 The diagram shows the structure of the middle plate 4. The middle plate 4 is a circular wooden board, fixed to the top of the base plate 3 by screws, and the diameter of the middle plate 4 is larger than the diameter of the base plate 3. Figure 8 The diagram shows the structure of the upper panel 5. The upper panel 5 is a circular wooden board, fixed to the top of the middle panel 4 with screws. The diameter of the upper panel 5 is larger than that of the middle panel 4. Circular panels with gradually increasing diameters are arranged from bottom to top. This effectively increases the area of ​​the top panel while ensuring strength, ensuring that more dishes can be placed on the table when put into use. Figure 5 As shown, the bottom edges of the base plate 3, middle plate 4, and top plate 5 are all chamfered to prevent customers from accidentally bumping into the table edge while dining. They are also made of wood, which is lightweight and easy to process and move. When fixed, the structure relies on the cooperation of structural adhesive and screws to make the overall structure more stable.

[0050] like Figure 6 As shown, a square slot 6 is provided on the top of the base plate 3, and a through slot 7 is provided at the bottom of the slot 6 and extends through the base plate 3. The side length of the slot 6 is greater than the side length of the through slot 7. The slot 6 and the through slot 7 are used for fixing the subsequent drive unit. Figure 10 As shown, the bottom of the card frame 16 is integrally connected to the fixed frame 17, and the card frame 16 and the fixed frame 17 are internally connected. The side length of the card frame 16 is equal to the side length of the card slot 6, and the side length of the fixed frame 17 is equal to the side length of the through slot 7. Therefore, during actual installation, the fixed frame 17 is inserted into the through slot 7, while the card frame 16 is inserted into the card slot 6. Under the dragging action at the bottom of the card slot 6, it cannot fall down. The cylinder body of the lifting cylinder 18 is fixed inside the fixed frame 17, and the guide rod of the lifting cylinder 18 is connected to the carrier plate 19. The turntable table is fixed on the top of the carrier plate 19. Under the action of the lifting cylinder 18, the carrier plate 19 and the turntable table are driven to rise and fall. When the driving force fails, the card frame 16 connected to the fixed frame 17 can be removed from the top of the card slot 6 for corresponding inspection and replacement, and then reinserted into the card slot 6. The insertion design avoids the cumbersome process caused by screwing and the problem of loose fixing.

[0051] The guide plate 20 is fixed to the top of the frame 16 and is used to guide the lifting movement of the lifting cylinder 18, such as...Figure 11 As shown, the guide plate 20 includes a scissor plate 22, a cone plate 23, a cone surface 24, a wedge block 25, and a notch 26. There are two scissor plates 22, which are horizontally crossed and fixed together, with an included angle of 90° between them. A guide hole 21 is formed at the intersection of the two scissor plates 22, and the diameter of the guide hole 21 is equal to the diameter of the guide rod of the lifting cylinder 18. The guide rod of the lifting cylinder 18 passes through the guide hole 21, and the verticality of the lifting cylinder 18's lifting movement is ensured by the guiding effect of the guide hole 21. A conical plate 23 is integrally connected to the end of the scissor lift plate 22. The conical plate 23 has two sets of opposite conical surfaces 24, and the included angle between the two sets of conical surfaces 24 is 90°. In actual fixing, the conical plate 23 is fixed to the inner angle of the frame 16 (the inner right angle of the frame 16 is coated with structural adhesive, and the two sets of opposite conical surfaces 24 on the conical plate 23 are respectively bonded to the right angle of the inner side of the frame 16, such as...). Figure 10 As shown, the engagement of the conical plate 23 with the inner right angle of the frame 16 effectively prevents deformation of the wooden frame 16. Furthermore, the fixation at the inner right angle is more secure than fixing to the inner edge of the frame 16. The wedge block 25 is fixed at the included angle of the two sets of scissor plates 22 to improve the structural strength at the guide hole 21. A notch 26 is provided between the scissor plates 22 and the frame 16, through which the power cord connected to the lifting cylinder 18 passes and rests on the base plate 3.

[0052] like Figure 7 As shown, the middle plate 4 has a first carrier groove 8 and a first storage groove 9 that are interconnected, as follows: Figure 8 As shown, the upper plate 5 has a second carrier plate groove 10 and a second storage groove 11 that are interconnected. The first carrier plate groove 8 and the second carrier plate groove 10 are fitted together, and the first storage groove 9 and the second storage groove 11 are fitted together. The diameter of the carrier plate 19 is equal to the diameter of the first storage groove 9 and the second storage groove 11. Figure 3 As shown, when the lifting cylinder 18 drives the carrier plate 19 to rise and fall, the carrier plate 19 will rise and fall within the first carrier plate groove 8 and the second carrier plate groove 10. The first carrier plate groove 8 and the second carrier plate groove 10 are used to provide accommodating space for the carrier plate 19 when it descends. The power cord and other components connected to the lifting cylinder 18 pass through the notch 26 and are placed in the first storage groove 9 and the second storage groove 11.

[0053] like Figure 8 As shown, the ball pad groove 13 is circumferentially formed on the top of the upper plate 5 for mounting the ball pad 27. Figure 9 The image shown is an enlarged view of the ball pad groove 13. The ball pad groove 13 includes a limiting groove 14 and an insert groove 15. The limiting groove 14 is opened at the top of the upper plate 5, and the insert groove 15 is opened at the bottom of the limiting groove 14. The diameter of the insert groove 15 is smaller than the diameter of the limiting groove 14.

[0054] The ball pad 27 is embedded in the ball pad groove 13. When the lifting cylinder 18 drives the load plate 19 to rise, the rotating table dining table is away from the ball pad 27. When the lifting cylinder 18 drives the load plate 19 to descend, the rotating table dining table is lowered to rest on the ball pad 27. The ball pad 27 is used to support the rotating table dining table and facilitate the rotation of the rotating table dining table. As shown in Figures 12-16 The ball pad 27 is shown in the schematic view, which includes the embedded plate 28, the ball cavity 29, the ball groove 30, the ball 31, the ball 32, the outer limiting plate 33, the inner shaft shoulder 34, the outer shaft shoulder 35, the first spring groove 36, the inner limiting plate 37, the second spring groove 38, the spring 39 and the arc surface 40. The embedded plate 28 is cylindrical. The diameter of the embedded plate 28 is equal to the diameter of the embedded groove 15. The height of the embedded plate 28 is equal to the depth of the embedded groove 15. Therefore, the embedded plate 28 is directly embedded in the embedded groove 15 during actual installation. As shown in Figure 15 , 16 The ball cavity 29 is opened at the top of the embedded plate 28. The ball cavity 29 is semispherical and the opening is upward. The ball groove 30 is opened on the inner spherical wall of the ball cavity 29. The ball groove 30 is semispherical and the opening is outward. The ball 31 is arranged in the ball groove 30. The diameter of the ball 31 is equal to the diameter of the ball groove 30. As shown in Figure 16 The outer limiting plate 33 is annular and integrally connected to the top of the embedded plate 28. The inner diameter of the outer limiting plate 33 is smaller than the diameter of the embedded plate 28 and larger than the diameter of the ball cavity 29. Therefore, the top of the embedded plate 28 and the inner side of the outer limiting plate 33 form the inner shaft shoulder 34. The outer diameter of the outer limiting plate 33 is larger than the diameter of the embedded plate 28 and equal to the diameter of the limiting groove 14. The height of the outer limiting plate 33 is equal to the depth of the limiting groove 14. Therefore, the bottom of the outer limiting plate 33 and the outer side of the embedded plate 28 form the outer shaft shoulder 35. During actual installation, the embedded plate 28 is embedded in the embedded groove 15 and the outer limiting plate 33 is embedded in the limiting groove 14. The outer shaft shoulder 35 is clamped at the step formed by the limiting groove 14 and the embedded groove 15 to ensure the reliability of the installation of the embedded plate 28 and the outer limiting plate 33.

[0055] As shown in Figure 15 The inner limiting plate 37 is annular. The height of the inner limiting plate 37 is equal to the height of the outer limiting plate 33. The inner limiting plate 37 is placed on the inner shaft shoulder 34. The outer side of the inner limiting plate 37 leaves a small gap with the inner side of the outer limiting plate 33 to ensure that the inner limiting plate 37 can slightly move in the horizontal direction in the outer limiting plate 33. The inner side of the outer limiting plate 33 is relatively provided with the first spring groove 36. The outer side of the inner limiting plate 37 is relatively provided with the second spring groove 38. The first spring groove 36 and the second spring groove 38 are used in cooperation. The elastic member is arranged in the first spring groove 36 and the second spring groove 38. The horizontal slight movement of the inner limiting plate 37 is realized by the elastic force of the elastic member (the elastic member is the spring 39 or the elastic ball). As shown in Figure 15As shown, the inner side of the inner limiting plate 37 is provided with an arc surface 40, and the diameter of the arc surface 40 gradually expands from top to bottom, which ensures the subsequent clamping of the rolling ball 32. Figure 13 、 14 As shown, the rolling ball 32 is arranged in the ball cavity 29, and the bottom of the rolling ball 32 abuts against the rolling ball 31, and the upper half of the rolling ball 32 is in conformity with the arc surface 40. Since the arc surface 40 is in conformity with the upper half of the rolling ball 32, under the action of the rolling ball 31, the rolling ball 32 can only rotate in the ball cavity 29 and cannot be separated from the ball cavity 29. Since the height of the panel 28 is equal to the depth of the embedding groove 15, and the height of the outer limiting plate 33 is equal to the depth of the limiting groove 14, when the panel 28 and the outer limiting plate 33 are embedded in the embedding groove 15 and the limiting groove 14 respectively, 1 / 3 of the top of the rolling ball 32 is exposed on the outer surface of the upper plate 5. The lifting cylinder 18 drives the carrier plate 19 to descend, and the rotating dining table abuts against the rolling ball 32. At this time, the position of the rotating dining table is the position of the rotating dining table when the guests eat. Since the rotating dining table abuts against the rolling ball 32, the rotating dining table is supported by the rolling ball 32, preventing the rotating dining table from being placed on one side and causing the table to tilt due to too many dishes. Moreover, the rolling ball 32 abuts against the rolling ball 31, so that when the guests rotate the rotating dining table, the rotating dining table will press the rolling ball 32 to roll in the ball cavity 29 synchronously. Under the action of the rolling ball 32 and the rolling ball 31, the rotating dining table rotates more stably. The elastic member (spring 39 or elastic ball) is arranged between the outer limiting plate 33 and the inner limiting plate 37. When the inner limiting plate 37 slightly moves in the horizontal direction, it will drive the rolling ball 32 to slightly move horizontally when rolling, avoiding the problem that the rotating dining table rotates poorly due to the rolling ball 32 being stuck (when the inner limiting plate 37 slightly moves horizontally, since the arc surface 40 is always in conformity with the upper half of the rolling ball 32, the rolling ball 32 will not be separated from the ball cavity 29).

[0056] As shown in Figure 8 The drainage groove 12 is arranged on the top of the upper plate 5 and is annular, which is used to collect the water overflowing from the rotating dining table, and facilitates the subsequent cleaning of the cleaning personnel. The ball mat 27 is located on the inner side of the annular drainage groove 12. When the lifting cylinder 18 drives the carrier plate 19 to descend, the rotating dining table abuts against the top of the rolling ball 32. The outer diameter of the rotating dining table is slightly smaller than the outer diameter of the annular drainage groove 12, so that the water overflowing from the rotating dining table will not fall on the edge of the upper plate 5 (i.e. the area where the guests dine), but will fall into the drainage groove 12. Embodiment

[0057] The technical content of the second embodiment is almost the same as that of the first embodiment, and the only difference is that the water inlet groove 41 is arranged on the outer side of the drainage groove 12 in the second embodiment, which facilitates the water overflowing from the rotating dining table to flow into the drainage groove 12, as shown in Figure 17 、 18As shown in the drawings, the water guide groove 41 is circumferentially arranged outside the drain groove 12 and is inclinedly arranged, and the lowest part of the water guide groove 41 is connected with the drain groove 12. By arranging the water guide groove 41 inclinedly towards the drain groove 12, the water overflowed from the rotary dining table can be more conveniently guided into the drain groove 12. Embodiment

[0058] The technical content of the embodiment three is almost the same as that of the embodiment one, and the only difference is that the embodiment three is provided with the annular water guide groove 41 outside the drain groove 12, which is more convenient for the water overflowed from the rotary dining table to flow into the drain groove 12, as shown in the drawings. Figure 19 As shown in the drawings, the water guide groove 41 is inclinedly arranged, and the lowest part of the water guide groove 41 is connected with the drain groove 12. By arranging the annular water guide groove 41 outside the drain groove 12, it is ensured that the water overflowed from the rotary dining table in any direction can flow into the drain groove 12 through the water guide groove 41.

[0059] The above embodiments are only for illustrating the technical concept and characteristics of the present application, and the purpose is to enable the person skilled in the art to understand the content of the present application and to implement it, and cannot limit the protection scope of the present application. Any equivalent changes or modifications made according to the spirit and essence of the present application shall be covered within the protection scope of the present application.
