Detailed Implementation

[0041] The present invention will now be described in further detail with reference to the accompanying drawings.

[0042] First Embodiment

[0043] Referring to Figures 1 to 6, a rotating support mechanism 2 includes:

[0044] Retaining ring 22;

[0045] A rotating ring 21 is rotatably connected to a fixed ring 22; the outer circumferential surface of the rotating ring 21 is provided with a first protruding tooth 210.

[0046] Referring to Figure 3, the rotating ring 21 is fitted onto the fixed ring 22. To improve the smoothness of rotation, a rolling element 20 can be provided between the rotating ring 21 and the fixed ring 22. The rolling element 20 can be a ball or a cylindrical roller. When the rolling element 20 is set as an inclined cylindrical roller, the rotating support mechanism 2 is better in terms of radial and axial force, and the rotation is more stable.

[0047] The push-pull locking part 23 includes a locking block 231 for limiting the rotation position or angle of the rotating ring 21;

[0048] Referring to Figures 1, 2, and 4, the locking block 231 can move closer to and further away from the rotating ring 21. The locking block 231 is provided with a second protruding tooth 2310 that engages with the first protruding tooth 210; that is, the push-pull locking part 23 can limit the rotation position or angle of the rotating ring 21. When the locking block 231 approaches the rotating ring 21 and the second protruding tooth 2310 engages with the first protruding tooth 210, the rotating ring 21 is locked or locked; when the locking block 231 approaches the rotating ring 21 and the second protruding tooth 2310 disengages from the first protruding tooth 210, the rotating ring 21 rotates freely.

[0049] And a limiting part 24, which includes a first limiting member 241 and a second limiting member 242;

[0050] Referring to Figures 5 and 6, the first limiting member 241 is linked with the rotating ring 21, and the second limiting member 242 is fixedly set.

[0051] Both the first limiting member 241 and the second limiting member 242 are equidistant from the center of the rotating ring 21; when the rotating ring 21 rotates to a preset angle, the first limiting member 241 and the second limiting member 242 come into contact. The first limiting member 241 and the second limiting member 242 are set to limit the rotation range of the rotating ring 21, causing the rotating ring 21 to rotate within the limited angle range and preventing the rotating ring 21 from rotating arbitrarily.

[0052] Referring to Figure 6, the rotating ring 21 is connected to the receiving frame 30, and the fixing ring 22 is connected to the first component 111; the first limiting member 241 is connected to the circular plate 301 of the receiving frame 30; and the second limiting member 242 is connected to the first component 111.

[0053] Both the first limiting member 241 and the second limiting member 242 are located on the outside of the rotating ring 21.

[0054] The number of the first limiting member 241 and the second limiting member 242 is one.

[0055] In the initial state, the first limiting member 241 is located in front of the rotating ring 21, and the second limiting member 242 is located behind the rotating ring 21, that is, the first limiting member 241 and the second limiting member 242 are arranged approximately 180 degrees apart. Taking the initial state as the starting point of rotation, the rotating ring 21 is restricted to rotate approximately 180 degrees clockwise or counterclockwise, forming a limit point for rotation, thereby preventing the rotating ring 21 from rotating too much in a certain direction, and also facilitating timely return to its original position.

[0056] Both the first limiting member 241 and the second limiting member 242 can be structures such as screws, protrusions, and cams.

[0057] The outer diameter of the rotating ring 21 is between 160mm and 185mm, and the outer diameter of the fixed ring 22 is between 110mm and 130mm. Thus, both the rotating ring 21 and the fixed ring 22 are relatively large, which helps to improve the strength under stress and makes rotation more stable.

[0058] Referring to Figure 4, the locking block 231 is fork-shaped and has at least two fork arms, each fork arm having a corresponding second convex tooth 2310, thereby improving the reliability of engagement.

[0059] The push-pull locking part 23 is located on one side of the rotating ring 21, and the locking block 231 moves horizontally towards and away from the rotating ring 21.

[0060] Specifically, referring to Figure 4, the push-pull locking part 23 also includes a slide bar 233, a slide block 236, a handle 232, and a bracket 235;

[0061] The middle part of the slide rod 233 is slidably connected to the slide block 236. The slide block 236 is provided with a guide hole that matches it. The slide block 236 can be threaded to one end of the bracket 235. The bracket 235 is provided with a threaded hole that matches it. The other end of the bracket 235 is fixed to the first component 111 of the base assembly 1 by screws or bolts.

[0062] One end of the slide bar 233 is provided with a locking block 231, and the other end of the slide bar 233 is provided with a handle 232. Thus, the locking block 231 is driven to move closer to and further away from the rotating ring 21 by the handle 232.

[0063] Furthermore, referring to Figure 4, the push-pull locking part 23 also includes a linkage group 234, which plays a power transmission role. The linkage group 234 includes a first linkage 2341 and a second linkage 2342; the second linkage 2342 is L-shaped.

[0064] One end of the first link 2341 is hinged to the slide block 236, and the other end of the first link 2341 is hinged to the middle of the second link 2342.

[0065] One end of the second link 2342 is hinged to one end of the slide bar 233, and the other end of the second link 2342 is fixedly connected to the handle.

[0066] Therefore, by rotating the handle 232, the linkage 234 drives the locking block 231 to move; wherein, the aforementioned hinge structure can be a structure such as a rotating shaft and a shaft hole. Of course, the handle 232 can also drive the locking block 231 to move through a structure such as a cam.

[0070] The fixing ring 22 can be connected to the base assembly 1 by screws or the like, and the rotating ring 21 can be connected to the seat assembly 3 by screws or the like;

[0071] Therefore, by connecting the rotating support mechanism 2 to the seat assembly 3, the seat assembly 3 can be angle-adjusted, making it more convenient to use. Moreover, compared with ordinary shaft and bearing structures, the rotating support mechanism 2 has a larger size, better force distribution, greater stability, and smoother rotation. Furthermore, by limiting the rotation position or angle of the seat assembly 3 through the push-pull locking part 23, the seat assembly 3 is not easily rotated by external force after being rotated to the required angle, further improving the convenience of use and providing a better user experience.

[0072] Referring to Figure 10, the seat assembly 3 includes a support frame 30 and a seat support 31;

[0073] The support frame 30 includes a circular plate 301 and a side plate 302. The circular plate 301 can be connected to the rotating ring 21 by screws or the like. The bottom of the side plate 302 is connected to the circular plate 301, for example by welding. The top of the side plate 302 is connected to the seat bracket 31, for example by welding. Two side plates 302 are provided opposite each other. Thus, the seat assembly 3 is stably and reliably connected to the rotating support mechanism 2.

[0074] The circular plate 301 is connected to the first limiting member 241; the first component 111 of the base assembly 1 is connected to the second limiting member 242.

[0075] Referring to Figure 6, the edge of the circular plate 301 is provided with a groove 301a, and the bottom of the side plate 302 is provided with a boss 302b that mates with the groove 301a. The boss 302b is inserted into the groove 301a, which can improve the connection accuracy and strength between the side plate 302 and the circular plate 301, and facilitate the welding between the two.

[0076] Referring to Figure 11, the base assembly 1 includes a base frame 10 and an adjustment mechanism 11, with a fixing ring 22 located on the top of the adjustment mechanism 11;

[0077] The adjustment mechanism 11 can adjust the height and tilt angle of the seat assembly 3 to meet different usage needs and make the function more diversified.

[0078] The adjustment mechanism 11 includes a first component 111, a second component 112, a third component 113 and a fourth component 114 that are hinged together at the beginning and end to form a rhomboid closed-loop linkage structure. The first component 111 is connected to the fixed ring 22 and the third component 113 is connected to the base frame 10.

[0079] One end of the first telescopic body 115 is hinged to the first component 111, the second component 112 or the fourth component 114, and the other end of the first telescopic body 115 is hinged to the base frame 10, thereby driving the adjustment mechanism 11 to rotate through the first telescopic body 115, thereby adjusting the height position of the seat assembly 3; the first telescopic body 115 can be a cylinder or an electric push rod or the like.

[0080] Referring to Figure 12, the fourth component 114 includes a first frame 1141 and a second frame 1142. The first frame 1141 and the second frame 1142 can slide relative to each other to form a telescopic structure. The first frame 1141 is provided with a slider 1141a, and the second frame 1142 is provided with a groove 1142b that cooperates with the slider 1141a. One end of the second telescopic body 116 is hinged to the first frame 1141, and the other end of the second telescopic body 116 is hinged to the second frame 1142. The second telescopic body 116 drives the fourth frame to extend and retract, thereby adjusting the tilt angle of the first component 111, and thus adjusting the tilt angle of the seat assembly 3. The second telescopic body 116 can be a cylinder or an electric actuator, etc.

[0081] Referring to Figure 10, the seat assembly 3 includes a foot support 33, a seat support 31, and a back support 32 that are hinged together in sequence. A third telescopic body 321 can adjust the angle of the back support 32, and a fourth telescopic body 331 can adjust the angle of the foot support 33. Both the third telescopic body 321 and the fourth telescopic body 331 can be structures such as cylinders or electric actuators.
