[0023] Please refer to Figures 1-6 The utility model provides the following technical scheme: a seat with adjusting structure, including support leg 1 and installing the base 2 of support leg 1 top, the surface of base 2 is installed with cushion 3, and cushion 3 is installed with backrest 4 through support frame;

[0024] The bottom surface of base 2 is installed with positioning slide rail 5, and the one end opening of positioning slide rail 5 is connected with telescopic rod 6, and the other end of telescopic rod 6 is connected with rotating shaft 7, and the surface of rotating shaft 7 is rotatably connected with shaft sleeve 8, and the surface of shaft sleeve 8 is connected with leg support plate 9, and the surface close to rotating shaft 7 of leg support plate 9 is connected with positioning block 10, and the surface of positioning block 10 is connected with movable rod 11, and the other end of movable rod 11 is connected with linkage plate 12, and the side of linkage plate 12 is connected with linkage spring 13, and the other side of linkage plate 12 is connected with clamping rod 14.

[0025] Preferably, the leg support plate 9 forms a rotating structure with the rotating shaft 7 through the positioning block 10, and the linkage spring 13 is connected to the inner wall of the positioning block 10 at one end relative to the linkage plate 12.

[0026] In practical use, the leg support plate 9 is automatically locked by elastically compressing the linkage spring 13, thus preventing the leg support plate 9 from shaking.

[0027] Preferably, a set of slots 15 are provided on the surface of the rotating shaft 7 near the locking rod 14, and the set of slots 15 are distributed circumferentially about the axis of the rotating shaft 7.

[0028] In practical use, the locking rod 14 is fitted into the slot 15 on the surface of the rotating shaft 7, which facilitates locking and fixing the leg support plate 9 after the angle is adjusted.

[0029] Preferably, side plates 16 are installed on both sides of the base 2, and vertical rods 17 are connected to the surface of the side plates 16. An adjustment plate 18 is connected to the top opening of the vertical rod 17, and a handrail 19 is connected to the top of the adjustment plate 18.

[0030] In practical use, the armrest board 19 can be adjusted to different heights to make it easier for people of different body types to use the seat.

[0031] Preferably, the inner wall of the vertical rod 17 is connected to a limiting block 20, and the limiting block 20 and the opening on one side of the adjusting plate 18 form a sliding connection structure.

[0032] In practical use, the stability of the handrail 19 during the rising and falling process is ensured by sliding the opening on one side of the adjustment plate 18 along the limiting block 20.

[0033] Preferably, a locking bolt 21 is threaded through the outer side of the vertical rod 17, and the locking bolt 21 passes through the vertical rod 17 and forms a fitting structure with the slot on one side of the adjusting plate 18.

[0035] The working principle of this utility model is as follows: First, by rotating the leg support plate 9 on the surface of the rotating shaft 7, the movable rod 11 on the surface of the positioning block 10 is pulled, which drives the linkage plate 12 at one end of the movable rod 11 to pull the linkage spring 13, causing the locking rod 14 to move. Then, the leg support plate 9 is tilted at one end of the seat so that the tilt angle of the leg support plate 9 meets the user's needs. Then, the movable rod 11 is released. At this time, the compressed linkage spring 13 rebounds, causing the locking rod 14 to engage with the locking groove 15 on the surface of the rotating shaft 7, thereby... The leg support plate 9 can be quickly rotated and kept stable, thereby improving the comfort of the seat and allowing people of different body types to adjust the leg support plate 9 to different angles. In addition, by sliding the adjustment plate 18 at the bottom of the armrest plate 19 along the opening at the top of the vertical rod 17, the opening on one side of the adjustment plate 18 is driven along the limit block 20. Then, the locking bolt 21 is passed through the vertical rod 17 and engaged with the slot on one side of the adjustment plate 18, which facilitates the quick height adjustment of the armrest plate 19, making it convenient for people of different body types to rest their hands and improving the practicality of the seat.
