[0030] Specifically, Figures 4 to 7As shown, two annular grooves 301 are provided on the upper and lower sides of the gear plate 3, a plurality of fixing blocks 502 are arranged in the annular grooves 301, the upper cover 1 is provided with a plurality of first limiting components 6, a plurality of first ball tracks 101 are provided on the periphery of the first limiting components 6, and the balls 501 located on the upper side of the gear plate 3 are rolled on the first ball tracks 101, the lower cover 2 is provided with a plurality of second limiting components 7, a plurality of second ball tracks 201 are provided on the inner periphery of the second limiting components 7, and the balls 501 located on the lower side of the gear plate 3 are rolled on the second ball tracks 201.

[0031] The first limiting assembly 6 includes a first fixing rod 601, one end of which is fixedly arranged on the upper cover 1, and a first bearing 602 is arranged on the other end of the first fixing rod 601, and the first bearing 602 abuts against the inner side surface of the gear plate 3. The second limiting assembly 7 includes a second fixing rod 701, one end of which is fixedly arranged on the lower cover 2, and a second bearing 702 is arranged on the other end of the second fixing rod 701, and the second bearing 702 abuts against the outer side surface of the gear plate 3. The first bearing 602 is used to limit the inner side surface of the gear plate 3, and the second bearing 702 is used to limit the outer side surface of the gear plate 3, which does not affect the rotation of the gear plate 3 and can effectively prevent the gear plate 3 from shifting when rotating.

[0032] The driving assembly 4 is fixedly arranged in the lower cover 2, and the driving assembly 4 includes a motor 401, the motor 401 is connected to a driving gear 402, the driving gear 402 is meshedly connected to a driven gear 403, and the driven gear 403 is meshedly connected to the gear plate 3. When the motor 401 is started, the driving gear 402 is driven to rotate, and the driving gear 402 rotates to drive the driven gear 403 to rotate, and the driven gear 403 rotates to drive the gear plate 3 to rotate. When the lower cover 2 is installed on the supporting table legs and a turntable is fixedly installed above the upper cover 1, the turntable Dishes or other exhibits can be placed on the top, the lower cover 2 does not move, the upper cover 1 with the weight of the turntable superimposed will fit with the ball 501 located on the upper side of the gear plate 3, the upper cover 1 will be pressed on the top of the ball 501 on the upper side of the gear plate 3, when the driving assembly 4 is working, the gear plate 3 will rotate relative to the lower cover 2, at this time, the ball 501 located on the lower side of the gear plate 3 is to enhance the smoothness of the rotation of the gear plate 3 relative to the lower cover 2, the ball 501 on the lower side of the gear plate 3 will rotate in a circle along the second ball track 201; in addition, When the disc 3 rotates, the ball 501 on the upper side of the gear disc 3, the upper cover 1, and the turntable will rotate accordingly, that is, it can be understood that the turntable is pressed on the upper cover 1 by gravity, and the upper cover 1 and the ball 501 on the upper side of the gear disc 3 are pressed tightly against the upper surface of the gear disc 3. At this time, the gear disc 3, the ball 501 on the upper side of the gear disc 3, the upper cover 1, and the turntable are a moving structure as a whole, and basically do not move relative to each other. At this time, the rotation of the gear disc 3 will eventually drive the turntable to rotate; and when the turntable is stopped by holding the turntable, The turntable and the upper cover 1 affected by the external force of the human hand will stop rotating, which is convenient for the user to pick up food or look at the exhibits on the turntable. Since the ball 501 on the upper side of the gear plate 3 is in rolling contact with the lower bottom surface of the upper cover 1, the continued rotation of the gear plate 3 only makes the upper ball 501 move along the circumference of the first ball track 101 on the bottom surface of the upper cover 1, that is, it does not affect the continued rotation of the driving gear 402; and when the hand leaves the turntable, the upper cover 1 loses the external force of the human hand and will continue to rotate driven by the driving gear 402.

[0033] like Figure 8 As shown, a brake device 8 is provided on the inner side of the upper cover 1, and the brake device 8 includes a brake rod 802, and a brake rubber block 801 is provided on the end of the brake rod 802, and the end of the brake rubber block 801 is against the inner side of the gear plate 3. The brake rod 802 is arranged on the inner side of the upper cover 1 to rotate from the outside to the inside. When the brake rod 802 is turned to make the brake rubber block 801 fit with the gear plate 3, the upper cover 1 and the gear plate 3 will be fixed together and will not slip against each other. When the motor 401 drives the gear plate 3 to rotate, the brake rubber block 801 will drive the upper cover 1 to rotate, effectively preventing the upper part of the upper cover 1 from slipping due to insufficient gravity and enhancing stability. When the brake rod 802 is turned to make the brake rubber block 801 move away from the gear plate 3, the upper cover 1 and the gear plate 3 are released from the fixed state, and the turntable can be stopped by holding the turntable.
