[0002] In modern homes and dining spaces, traditional fixed dining tables can no longer meet diverse needs, especially in family gatherings, friends gatherings, business meetings and other occasions. Fixed dining tables are often stretched due to space limitations and inconvenience in taking food. Therefore, revolving dining tables came into being. With a turntable design, you only need to rotate the turntable through a motor to rotate food or tableware to the front, without having to stand up or reach out, which greatly improves the comfort and convenience of dining.

[0003] However, as people's requirements for the functionality and aesthetics of the dining table continue to increase, the simple rotation function can no longer meet all the needs.

[0042] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below with reference to the accompanying drawings and implementation examples. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0043] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0044] In modern home and dining environments, fixed dining tables can no longer meet diverse needs, especially in social and business occasions. With its turntable design, the revolving dining table is driven by a motor, which improves the convenience and comfort of dining. However, as users' pursuit of functionality and aesthetics of dining tables increases, the lifting function of the turntable of the revolving dining table has become a new focus. The lifting function allows users to adjust the height of the turntable according to their needs to adapt to different occasions and diners. Although existing revolving dining tables already have lifting functions, there are generally shortcomings, such as complex bearing structures, heavy overall structures, and unstable lifting processes, which lead to shaking and affect the dining experience. In addition, as the load capacity of the turntable increases, the force required to start and stop the rotation gradually increases, further reducing the user's dining satisfaction.

[0045] To solve the above problems, please refer to Figures 1 to 5 The utility model provides an integrated dining table turntable structure, including:

[0046] The first transmission ring 20 is rotatably mounted on the dining table.

[0047] The driving component 50 is used to drive the first transmission ring 20 to rotate.

[0048] The second transmission ring 30 is arranged concentrically with the first transmission ring 20 relative to a preset axis and is rotationally connected. By utilizing a double-layer rotational connection relationship, it is less affected by the load and can drive the turntable structure to rotate without a large rotational driving force. The second transmission ring 30 can rotate synchronously with the first transmission ring 20.

[0049] The turntable mounting plate 40 is fixedly mounted on the second transmission ring 30 . The turntable mounting plate 40 serves as a top platform of the turntable structure and is used to mount a table.

[0050] In this embodiment, when the driving component 50 is working, it drives the first transmission ring 20 to rotate, the second transmission ring 30 is relatively stationary with the first transmission ring 20, and rotates with the rotation of the first transmission ring 20. When the second transmission ring 30 is pressed to stop by an external force, the second transmission ring 30 and the dining table are relatively stationary, and only the first transmission ring 20 is still rotating under the drive of the driving component 50.

[0051] See also Figure 3A plurality of first mounting through holes 31 are provided on the second transmission ring 30, and the plurality of first mounting through holes 31 are arranged along the circumferential direction of the second transmission ring 30. An adjustable resistance adjusting member 32 is installed on the first mounting through hole 31, and the resistance adjusting member 32 is screwed to the second transmission ring 30. One end of the resistance adjusting member 32 close to the first fixing ring 11 passes through the first mounting through hole 31, and is in contact with the axial end surface of the first transmission ring 20. This design can accurately control the contact force of the resistance adjusting member 32 on the first transmission ring 20, thereby realizing the precise adjustment of the rotational resistance between the first transmission ring 20 and the second transmission ring 30, so that the turntable structure is suitable for rotating tables of different specifications, thereby ensuring the stability and reliability of the turntable structure.

[0052] The resistance adjusting component 32 is an automatic adjusting component or a manual adjusting component. Common automatic adjusting components include a telescopic air pump, a hydraulic pump, etc. In a preferred embodiment, the resistance adjusting component 32 is a manual adjusting component.

[0053] See also Figure 4 The resistance adjustment member 32 comprises:

[0054] The abutment member 323 is used for abutting connection with the first transmission ring 20 .

[0055] The top tightening member 321 is used to adjust the contact force between the abutment member 323 and the first transmission ring 20. An internal thread is provided in the first mounting through hole 31, and an external thread 325 matched with the internal thread is provided on the top tightening member 321. The top tightening member 321 is installed in the first mounting through hole 31 and is threadedly connected to the second transmission ring 30. This connection method is both firm and easy to adjust. By rotating the top tightening member 321, the position of the top tightening member 321 in the first mounting through hole 31 can be accurately adjusted, thereby realizing the adjustment of the rotation resistance of the turntable structure.

[0056] It should be noted that the connection relationship between the pressing member 321 and the abutting member 323 is a rigid connection or an elastic connection. In a preferred embodiment, the connection relationship between the pressing member 321 and the abutting member 323 is an elastic connection.

[0057] Here, the abutment member 323 includes:

[0058] The friction ball head 3231 is in contact with the first transmission ring 20 .

[0059] The elastic member 322 is installed between the pressing member 321 and the friction ball head 3231 to realize the elastic connection with the friction ball head 3231. The elastic member 322 is used to provide an elastic reaction force to be converted into a resistance force.

[0060] With the elastic reaction force provided by the elastic member 322, it is ensured that the friction ball head 3231 can be in close contact with the end surface of the first transmission ring 20. This design can adapt to different rotation resistance requirements, making the turntable structure more stable when rotating and having better operability.

[0061] Specifically, when the tightening member 321 is tightened, based on the elastic properties of the elastic member 322, the elastic member 322 is squeezed to generate an elastic reaction force, which acts on the first transmission ring 20 through the friction ball head 3231 and is converted into a resisting friction force. By utilizing this principle, the rotational resistance between the first transmission ring 20 and the second transmission ring 30 is adjusted. The resistance adjustment component 32 has a simple structure, is easy to implement, and has good adjustment effect and stability.

[0062] A first guide limit column 324 is provided at one end of the friction ball head 3231 away from the first transmission ring 20, and one end of the elastic member 322 away from the tightening member 321 is sleeved on the first guide limit column 324 and fixedly connected to the friction ball head 3231, which not only ensures a stable connection between the friction ball head 3231 and the elastic member 322, but also provides a guiding effect on the elastic member 322. Through the first guide limit column 324, the elastic member 322 can maintain a stable motion trajectory when compressed or stretched, thereby preventing the friction ball head 3231 from slipping when the first transmission ring 20 and the second transmission ring 30 rotate, thereby ensuring that the resistance force of the friction ball head 3231 to the first transmission ring 20 is always uniform and stable, further enhancing the stability and reliability of the rotation resistance of the turntable structure.

[0063] For further information, see Figure 1 , Figure 2 , Figure 3 and Figure 5 A first fixing ring 11 is provided at one end of the dining table close to the first transmission ring 20. The first fixing ring 11 is fixedly connected to the dining table through the chassis 10. The chassis 10 serves as a basic supporting component for stably installing the turntable structure and bearing weight, thereby ensuring the stability and load-bearing capacity of the entire turntable structure. The first transmission ring 20 is sleeved on the first fixing ring 11 and rotatably connected to ensure that the first transmission ring 20 can stably rotate on the first fixing ring 11 to realize the rotation function of the turntable structure. The driving component 50 is installed on the chassis 10 and is arranged on the side of the first fixing ring 11. The driving component 50 is used to provide rotational power to ensure the stable rotation of the turntable structure. A first annular groove 111 is provided on the outer circumference of the first fixing ring 11, and a second annular groove 23 is provided on the inner circumference of the first transmission ring 20. The first annular groove 111 and the second annular groove 23 together constitute a first guide slide channel 70, and a ball bearing is installed in the first guide slide channel 70.

[0064] A transmission gear 51 is installed at the transmission end of the driving component 50, and the transmission gear 51 is meshed and connected with the first transmission ring 20. When the driving component 50 is working, the first transmission ring 20 is driven to rotate through the transmission gear 51. A lifting adjustment mechanism 60 is also provided at the bottom of the chassis 10. The lifting adjustment mechanism 60 is used to control the lifting height of the chassis 10, thereby adjusting the height of the entire turntable structure. The lifting end of the lifting adjustment mechanism 60 is fixedly connected to the chassis 10 to ensure the stability and safety of the overall structure during the lifting process. Through the lifting adjustment mechanism 60, the user can easily adjust the height of the turntable structure according to needs to adapt to different occasions and diners' needs, further improving the comfort and convenience of dining.

[0065] Please refer to the figure Figure 1 and Figure 3 A transmission tooth groove 22 adapted to the transmission gear 51 is opened on the outer peripheral side of the first transmission ring 20. The transmission gear 51 is meshed and connected with the first transmission ring 20 through the transmission tooth groove 22, thereby achieving an efficient and stable transmission effect, making the rotation of the turntable structure smoother and more accurate.

[0066] Furthermore, the first transmission ring 20 is provided with a convex ring 21 along its axial direction, and the second transmission ring 30 is sleeved on the convex ring 21 and movably connected thereto. The convex ring 21 serves as a bridge connecting the first transmission ring 20 and the second transmission ring 30 to ensure stable connection and rotation transmission therebetween. A third annular groove 211 is provided on the outer peripheral side of the convex ring 21, and a fourth annular groove 33 is provided on the inner peripheral side of the second transmission ring 30. The third annular groove 211 and the fourth annular groove 33 together constitute a second guide channel 80, and balls are installed in the second guide channel 80.

[0067] It should be noted that the first transmission ring 20 and the convex ring 21 are integrally formed, or the first transmission ring 20 and the convex ring 21 are two independent components that are fixed together by fastening connectors.

[0068] The first guide channel 70 and the second guide channel 80 provide rolling space for the balls, ensuring the precise rotational movement of the first transmission ring 20 relative to the first fixed ring 11 and the second transmission ring 30 relative to the convex ring 21, greatly reducing the friction of the turntable structure during rotation, thereby improving the lifting stability and rotation smoothness of the turntable, so that a smaller rotational force is required to drive the turntable structure to rotate. At the same time, the introduction of the balls reduces the wear between the rotating parts of the turntable structure, further enhancing the durability and service life of the turntable structure.

[0069] The outer diameter of the convex ring 21 is smaller than the outer diameter of the first transmission ring 20. While ensuring the structural stability, it effectively reduces the space occupied by the turntable structure in the radial direction, improves space utilization, and also reduces the friction and interference risk between the convex ring 21 and other components, further improving the movement smoothness and service life of the turntable structure.

[0070] In terms of the rotation control of the turntable structure, the specific working process is as follows:

[0071] When the driving component 50 is working, the first transmission ring 20 is driven to rotate through the transmission gear 51. At this time, due to the resistance force provided by the second transmission ring 30's own weight or the resistance adjusting member 32, a rotational resistance is generated between the first transmission ring 20 and the second transmission ring 30. In the absence of external interference, the second transmission ring 30, which is coaxially connected to the first transmission ring 20, rotates with the first transmission ring 20 under the action of the rotational resistance.

[0072] When the second transmission ring 30 is pressed to stop by an external force, the rotational driving force provided by the driving component 50 overcomes the rotational resistance and still drives the first transmission ring 20 to rotate. That is, at this time, only the first transmission ring 20 is in a rotating state. Due to the arrangement of the first guide channel 70, the second guide channel 80 and the ball, a double-layer rotational connection relationship is realized. The resistance encountered during the rotation process is greatly reduced, and it is insensitive to changes in the weight and size of the load. The rotational resistance that the driving component 50 needs to overcome changes little, and the pressing force required by the user to press to stop is small.

[0073] When the pressing force of the pressing stop is cancelled, the second transmission ring 30 which is coaxially connected to the first transmission ring 20 rotates together with the first transmission ring 20 again under the action of the rotation resistance.

[0074] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the principles of the present invention should be included in the protection scope of the present invention.
