[0007] Furthermore, in this embodiment, a plurality of balls are assembled between the first ball bearing groove and the second ball bearing groove, and the balls are made of wear-resistant plastic or wear-resistant metal.

[0008] Furthermore in this embodiment, a gap is reserved between the fixed annular seat and the rotating annular seat.

[0009] Furthermore in this embodiment, the cross-section of the rotating annular seat is a groove-shaped structure, which includes an annular base plate, an inner wall and an outer wall perpendicularly connected to the annular base plate; a limiting member is provided on the inner wall or the outer wall of the rotating annular seat, the limiting member including at least a pressure plate that can be pressed against the bottom of the fixed annular seat, and a protruding rib that abuts against the pressure plate is provided at the bottom of the fixed annular seat.

[0010] In this embodiment, the fixed support block is further described as a fixed connector or a support pad.

[0011] In this embodiment, the desktop pad is a rubber pad fixed to the top surface of the rotating annular seat.

[0012] Compared with the prior art, the beneficial technical effects of this utility model are as follows: In this invention, the rotating ring seat and the fixed ring seat are mainly driven by ball bearings, thereby reducing the contact area between them and thus reducing friction and friction noise. In addition, a limiting member is fastened to the bottom of the fixed ring seat, which can limit the rotating ring seat axially and horizontally, ensuring the levelness of the table during use.

[0013] The present invention will be further described below with reference to the accompanying drawings. Figure 1 This is a schematic diagram of the bottom structure of the desktop rotating mechanism of this utility model; Figure 2 This is a schematic diagram of the top surface structure of the desktop rotating mechanism of this utility model; Figure 3 This is a schematic diagram of the assembly structure of the desktop rotating mechanism of this utility model; Figure 4 for Figure 3 A magnified cross-section diagram of a portion of the middle section.

[0014] Explanation of reference numerals in the attached drawings: 1. Rotating annular seat; 11. First ball bearing groove; 2. Fixed annular seat; 21. Second ball bearing groove; 3. Limiting component; 4. Fixed support block; 5. Tabletop pad; 6. Ball bearing. Detailed Implementation

[0015] refer to Figure 1 This embodiment discloses a desktop rotation mechanism, including a fixed ring seat 2, a rotating ring seat 1 covering the fixed ring seat 2, and a ball bearing 6 with a uniform circumferential interval between the fixed ring seat 2 and the rotating ring seat 1; wherein five limiting members 3 are uniformly spaced inside the rotating ring seat 1 to prevent it from disengaging from the fixed ring seat 2.

[0016] refer to Figure 1Six fixed support blocks 4 are evenly spaced at the bottom of the fixed annular seat 2; Reference Figure 2 Five tabletop pads 5 are evenly spaced on the top surface of the fixed annular seat 2.

[0017] In this embodiment, reference Figure 3 and Figure 4 The fixed annular seat 2 has a second ball bearing reserved groove 21 integrally formed on it, and the rotating annular seat 1 has a first ball bearing reserved groove 11 integrally formed on it at the position corresponding to the second ball bearing reserved groove 21. Both the second ball bearing reserved groove 21 and the first ball bearing reserved groove 11 are annular grooves.

[0018] A ring of balls 6 is assembled between the first ball reserved groove 11 and the second ball reserved groove 21. The ball 6 is made of wear-resistant plastic or wear-resistant metal; specifically, lightweight wear-resistant plastics, such as polyoxymethylene, polypropylene and nylon, are preferred; among them, the balls made of nylon material have less friction during use and have the effect of low noise.
