[0070] As Figures 1 to 7 , Figure 10 and Figure 11As shown, in some examples, the support body 100 comprises: a column mechanism 110, the top end of which is annularly provided with a groove 101; a rotating disc positioning mechanism 120, which is rotatably installed on the column mechanism 110, and the rotation axis of which coincides with the axes of the grooves 101; a steel ball 130, which is slidably installed in the rotating disc positioning mechanism 120, and is matched with the groove 101; and an elastic member 140, which is arranged between the rotating disc positioning mechanism 120 and the steel ball 130, and is used to make the steel ball 130 tightly contact with the groove 101.

[0071] In the technical scheme, the support body 100 comprises the column mechanism 110, the rotating disc positioning mechanism 120, the steel ball 130 and the elastic member 140, wherein the column mechanism 110 is the core support component of the support body 100, which plays a role in connecting and bearing the upper structure of the leisure chair, and the top end of the column mechanism 110 is annularly provided with the groove 101; the rotating disc positioning mechanism 120 is rotatably installed on the column mechanism 110, and the rotation axis of the rotating disc positioning mechanism 120 coincides with the axes of the grooves 101, the rotation axis of the rotating disc positioning mechanism 120 strictly coincides with the axes of the grooves 101, which ensures the stability and fluency of the rotation of the rotating disc positioning mechanism 120, and provides a good basic condition for the cooperation of the steel ball 130 and the elastic member 140; the size of the steel ball 130 is matched with the depth and opening size of the groove 101, and when the rotating disc positioning mechanism 120 rotates in the use process of the leisure chair, the steel ball 130 can smoothly roll and sequentially fall into the groove 101, so as to realize the positioning and locking functions of the rotating disc positioning mechanism 120 at different angle positions.

[0072] The column mechanism 110 comprises: a fixed seat 111; a rotating shaft 112, which is arranged on the fixed seat 111, and the grooves 101 are annularly and equidistantly arranged along the axis of the rotating shaft 112; and the rotating disc positioning mechanism 120 is arranged on the rotating shaft 112.

[0073] Through the above arrangement, the column mechanism 110 and the rotating disc positioning mechanism 120 can be stably connected and operated, and a stable basis is provided for the whole device.

[0074] The steel ball 130 and the elastic member 140 are a set of locking assemblies, the locking assemblies are at least one set, and are annularly and equidistantly arranged on the rotating disc positioning mechanism 120.

[0075] As Figures 1 to 11As shown, in some examples, the leg support assembly 300 includes: a leg flip-fixing plate 310, rotatably mounted on the seat back 200, and the connecting rod assembly 400 connected to the leg flip-fixing plate 310; a leg support plate 320, rotatably mounted on the leg flip-fixing plate 310; and a positioning assembly 330 disposed between the leg support plate 320 and the leg flip-fixing plate 310 for fixing the leg support plate 320 and the leg flip-fixing plate 310 relative to each other.

[0076] In this technical solution, the leg support assembly 300 includes a leg flip fixing plate 310, a leg support plate 320, and a positioning assembly 330. The leg flip fixing plate 310 is rotatably mounted on the seat back 200. For example, a slewing bearing can be used for connection at the joint to ensure that the leg flip fixing plate 310 rotates smoothly and steadily on the seat back 200, and maintains high-precision rotation performance during long-term use, reducing wear and noise caused by poor rotation. Through the coordinated work of the leg flip fixing plate 310, the leg support plate 320, and the positioning assembly 330, the leg support assembly 300 can be angled under the linkage of the seat back 200, and the angle of the leg support plate 320 can be flexibly adjusted according to the user's needs, providing the user with personalized, comfortable, and stable leg support, effectively improving the user experience and functionality of the lounge chair.

[0077] like Figures 1 to 11 As shown, in some examples, the positioning component 330 includes: a locking bolt 331 threaded onto the leg flipping fixing plate 310; and a leg flipping limiting plate 332 fixedly mounted onto the leg support plate 320. The leg flipping limiting plate 332 has a plurality of locking holes 301 circumferentially and equidistantly formed on it, which are adapted to the locking bolt 331. When the locking bolt 331 is connected to the locking holes 301, the leg support plate 320 is relatively fixed to the leg flipping fixing plate 310.

[0078] In this technical solution, the positioning component 330 includes a locking bolt 331 and a leg flipping limit plate 332. When the user needs to adjust the angle of the leg support plate 320, he / she only needs to loosen the locking bolt 331 to separate it from the current locking hole 301. During this process, since the connection between the locking bolt 331 and the leg flipping limit plate 332 is temporarily released, the leg support plate 320 can rotate freely around the rotation axis on the leg flipping fixing plate 310. The user can rotate the leg support plate 320 to a suitable angle according to his / her own comfort needs.

[0079] When the angle adjustment is completed, the locking bolt 331 is tightened again to be inserted into the locking hole 301 in the corresponding position. During the tightening process, as the locking bolt 331 is gradually screwed in, the axial force generated by the threaded cooperation between the locking bolt 331 and the locking hole 301 tightly fixes the leg turnover limiting disc 332 in the current position, and further fixes the leg supporting plate 320 and the leg turnover fixing plate 310 relative to each other. In this way, under the condition that the locking bolt 331 and the locking hole 301 are tightly connected, the structure of the entire leg bearing assembly 300 is stable, and the user can rest safely relying on the adjusted leg support structure without worrying about the accidental rotation of the leg supporting plate 320 causing unstable support.

[0080] Through the cooperative work of the locking bolt 331 and the leg turnover limiting disc 332, the positioning assembly 330 can accurately and reliably realize the relative fixation of the leg supporting plate 320 and the leg turnover fixing plate 310 at different angles, providing the user with a stable, comfortable and adjustable leg support experience, and further improving the use performance and comfort of the entire leisure chair.
