[0042] The electric rotating table as an innovative catering auxiliary equipment has been widely used in various restaurants and family gatherings in recent years. It not only realizes the convenience and efficiency of the dining table through automation technology, but also greatly enriches the dining experience of diners. The traditional dining table layout often limits the communication and interaction between diners, especially when dining together, the diners at the edge of the table often have difficulty reaching the dishes far from themselves. The emergence of the electric rotating table ingeniously solves this problem. Through the built-in motor drive, the internal rotating gear drives the top disc to rotate, and the tabletop panel is placed on the top disc, so that the tabletop panel can rotate smoothly and uniformly, so that each dish can be evenly displayed in front of each diner, ensuring the heat and taste of the dishes, and improving the interaction and sharing between diners.

[0043] However, according to the observation and research of the applicant, it is found that when the electric turntable is used in cooperation with the tabletop panel (or transparent glass disc), the diameter of the tabletop panel is often greater than the diameter of the electric turntable. For some large dining tables used for large gatherings, the diameter of the tabletop panel is even more than twice the diameter of the electric turntable. If the model of the electric turntable is not matched with the size and weight of the tabletop panel, the size of the tabletop panel is not suitable for the model of the electric turntable. At this time, the diameter of the tabletop panel is too large, the distance between the edge of the tabletop panel and the edge of the electric turntable is too long, and the force arm between the edge of the tabletop panel and the edge of the electric turntable is too long. When a heavy object (such as a pottery stove, a boxed beer, etc.) is placed on the edge of the tabletop panel, it is likely that the side of the electric turntable close to the heavy object will be subjected to excessive pressure, causing the internal rollers to deform, causing the tabletop panel to tilt, and even causing the side of the top disc not subjected to pressure to be lifted and separated from the bottom disc. This situation not only makes the rotation of the tabletop panel no longer smooth, but also may cause the food on the tabletop panel to slide or fall, posing a potential threat to the safety of diners. Therefore, how to optimize the design of the electric turntable so that the edge of the tabletop panel does not damage the internal structure of the electric turntable and the tabletop panel does not tilt when a heavy object is placed on the edge of the tabletop panel has become a problem that the applicant urgently needs to solve.

[0044] In view of this, the utility model provides an electric turntable to solve the above technical problems.

[0045] In an embodiment of the utility model, the electric turntable 100 includes a bottom disc 1, a top disc 2 and a rotating gear disc 3. Wherein, please refer to Figures 1 to 3 The top disc 2 is covered on the bottom disc 1, and the top disc 2 is provided with a plurality of buckling parts 21 extending towards the bottom disc 1, and the plurality of buckling parts 21 are arranged in a ring array with the center of the top disc 2 as the center, please refer to Figure 4 The bottom disc 1 is provided with a flange part 11 extending towards the top disc 2, and the flange part 11 is provided along the ring direction of the top disc 2, and the buckling part 21 is matched with the flange part 11; please continue to refer to Figures 1 to 3 The rotating gear disc 3 is arranged between the bottom disc 1 and the top disc 2, and the rotating gear disc 3 rotates coaxially with the top disc 2; the side of the bottom disc 1 facing the top disc 2 is provided with a first guide rail 12, and the side of the top disc 2 facing the bottom disc 1 is provided with a second guide rail 22, and the rotating gear disc 3 includes a gear ring 31 and at least three ball bearings 32, and the at least three ball bearings 32 are installed in the ring array on the gear ring 31 with the center of the gear ring 31 as the center, and the ball bearings 32 can roll along the first guide rail 12 and the second guide rail 22.

[0046] Specifically, the base plate 1 is fixed, the first guide rail 12 is arranged on the base plate 1 for the rolling of the ball 32, the first guide rail 12 and the second guide rail 22 are oppositely arranged, the projection of the first guide rail 12 towards the top plate 2 coincides with the second guide rail 22, the ball 32 is in contact with the first guide rail 12 and the second guide rail 22 at the same time, the friction between the ball 32 and the second guide rail 22 can drive the top plate 2 to rotate, and the rolling of the ball 32 is driven by the gear ring 31. The ball 32 is embeddedly installed in the gear ring 31, and the ball 32 can roll relative to the gear ring 31. In order to make the rolling of the ball 32 more smooth, a lubricating oil layer is coated between the ball 32 and the gear ring 31. The plurality of balls 32 roll with the rotation of the gear ring 31, so that the ball 32 can rotate on the first guide rail 12 and the second guide rail 22, the rotation center of the plurality of balls 32 is the same as the rotation center of the gear ring 31, and the rotation center of the top plate 2 is the same as the rotation center of the gear ring 31, so as to ensure the stability of the rotation of the top plate 2. In the embodiment, the number of balls 32 is twenty, the ball 32 is a steel ball, and the number of buckling parts 21 is eight. The buckling part 21 is arranged on the inner side of the top plate 2 to avoid affecting the appearance of the electric rotating table 100. When the top plate 2 is installed, the buckling part 21 cooperates with the flange part 11, so that the top plate 2 can be clamped on the base plate 1. When the top plate 2 is tilted due to external force, the base plate 1 can timely provide a pulling force to the top plate 2 to avoid excessive tilting of the top plate 2.

[0047] The technical scheme provided in the embodiment supports the rotation of the gear ring 31 and the top plate 2 by using single-layer balls 32. Since multiple layers of rollers are not required, and the contact area between the ball 32 and the first guide rail 12 and the second guide rail 22 is large due to the spherical surface of the ball 32, the pressure bearing capacity of the ball 32 is stronger than that of the roller, and the ball 32 is less likely to be damaged under pressure, thereby reducing the possibility that the deformation of the ball 32 causes the tilting of the tabletop panel. In addition, when the edge of the top plate 2 on one side is subjected to excessive pressure and the other side is about to be tilted, the cooperation between the buckling part 21 and the flange part 11 enables the top plate 2 to be subjected to a pulling force from the base plate 1, thereby avoiding the situation that the sudden tilting of the top plate 2 causes the excessive tilting of the tabletop panel, and further avoiding the situation that the dishes on the tabletop panel slide off.

[0048] Further, please refer to Figure 4In an embodiment of the utility model, buckle 21 includes first side wall 211 and buckle 212, buckle 212 is installed to the side of first side wall 211 towards bottom tray 1, flange part 11 includes second side wall 111 and flange 112, flange 112 is arranged to the side of second side wall 111 towards top tray 2, second side wall 111 and flange 112 are along the annular extension of top tray 2 and are arranged, flange 112 is protrudingly arranged towards first side wall 211, first gap F is arranged between buckle 212 and second side wall 111, second gap S is arranged between buckle 212 and flange 112;Definition: the length of flange 112 protruding second side wall 111 is L, the width of first gap F is W;L and W satisfy: W < L.Through the first gap F between buckle 212 and second side wall 111 is arranged, and the second gap S between buckle 212 and flange 112 is arranged, top tray 2 does not contact with bottom tray 1 when rotating, thereby avoiding the influence of the stable rotation of top tray 2.When one side of top tray 2 is subjected to greater pressure, the opposite side is inclined upward, at this time, the second gap S is reduced or disappears, and the bottom tray 1 contacts with the top tray 2, so that the bottom tray 1 can apply a pulling force to the top tray 2, avoiding the top tray 2 from continuing to tilt. The length L of the flange 112 protruding the second side wall 111 needs to be greater than the width W of the first gap F, to ensure that the flange 112 and the buckle 212 can contact when the top tray 2 is tilted upward.

[0049] In an embodiment of the utility model, any plane perpendicular to the annular direction of the top tray 2 is defined as a first plane; the projections of the first guide rail 12 and the second guide rail 22 on the first plane are both arc-shaped, and the radius of the arc shape is equal to the radius of the ball 32. Please refer to Figure 4 , any cross section of the first guide rail 12 and the second guide rail 22 is arc-shaped, by setting the radius of the arc shape equal to the radius of the ball 32, the contact area between the ball 32 and the first guide rail 12 and the second guide rail 22 is increased, so that the stress concentration area of the ball 32 after being stressed is more dispersed, thereby reducing the possibility of the ball 32 being crushed, in addition, the larger contact area can also reduce the pressure intensity that the top tray 2 and the bottom tray 1 bear, avoiding excessive deformation of the top tray 2 and the bottom tray 1.
