[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.
[0023] As Figures 1 to 4 shown, a folding seat of the present invention includes a combined support one 1, a combined support leg two 2, a seat board 3, a backrest 4, a handle one 5 and a handle two 6. The seat board 3 is rotatably connected between the combined support one 1 and the combined support leg two 2. The backrest 4 is rotatably connected to the end of the seat board 3. The handle one 5 is rotatably connected between the combined support one 1 and the backrest 4. The handle two 6 is rotatably connected between the combined support leg two 2 and the backrest 4. Both the combined support one 1 and the combined support leg two 2 include a first support leg 7, a second support leg 8, a V-shaped limit sleeve 9, a support shaft 10 and a connecting and reinforcing plate 11. The support shaft 10 is fixedly connected to the bottom of the V-shaped limit sleeve 9 through the connecting and reinforcing plate 11. The first support leg 7, the second support leg 8, the handle one 5 and the handle two 6 are all sleeved on the support shaft 10 and rotatably connected thereto. A strip-shaped through groove 12 is formed on the first support leg 7. A slide seat 13 is slidably arranged inside the strip-shaped through groove 12. The seat board 3 is rotatably connected to the slide seat 13 through a rotating shaft one 14. The seat board 3 is rotatably connected to the second support leg 8 through a rotating shaft two 15. The seat board 3 is rotatably connected to the backrest 4 through a rotating shaft three 16. The backrest 4 is rotatably connected to the handle one 5 and the handle two 6 through a rotating shaft four 17. A locking bolt 18 matching the slide seat 13 is inserted through the side of the first support leg 7;
[0024] If the seat needs to be folded so that the first support leg 7 and the second support leg 8 are closed, at this time, the sliding seat 13 moves down along the strip-shaped through groove 12, causing the seat board 3 to rotate around the second rotating shaft 15, realizing the folding of the seat board 3. The seat board 3 drives the backrest 4 to move through the third rotating shaft 16, and the backrest 4 drives the first handle 5 and the second handle 6 to move through the fourth rotating shaft 17. The first handle 5 and the second handle 6 rotate around the support shaft 10 simultaneously, thereby realizing folding and storage. When the seat is in use, it can be locked and reinforced by the locking bolt 18 to improve the overall stability;
[0025] as Figures 1 to 6 shown, both the first handle 5 and the second handle 6 include a handle body 19 and a limit connecting plate 20. A strip-shaped groove 21 is opened at the bottom end of the handle body 19. A number of first limit hooks 22 are fixedly arranged at the top end inside the strip-shaped groove 21. The bottom end of the limit connecting plate 20 is sleeved on the support shaft 10 and is rotatably connected thereto. A second limit hook 23 matching the first limit hook 22 is fixedly arranged at the top end of the limit connecting plate 20. Limit strips 24 are fixedly arranged at the top ends on both sides of the limit connecting plate 20, and the height of the limit strip 24 is less than the height of the strip-shaped groove 21;
[0026] When adjusting the angle of the backrest 4, pull the handle body 19 forward and slightly lift it to separate the second limit hook 23 from the first limit hook 22, and then continue to pull the handle body 19 forward or backward to adjust the angle of the backrest 4. By setting the height of the limit strip 24 to be less than the height of the strip-shaped groove 21, on the one hand, the limiting effect can be achieved, and on the other hand, the connection activity can be improved;
[0027] as Figures 1 to 4 shown, a headrest 25 is fixedly arranged at the top end of the side of the backrest 4, and anti-slip sleeves 26 are arranged at the bottom ends of both the first support leg 7 and the second support leg 8;
[0028] The comfort can be improved through the headrest 25, and the anti-slip performance can be improved through the anti-slip sleeves 26. At the same time, it can prevent the first support leg 7 and the second support leg 8 from directly contacting the ground and generating noise.
[0029] During work, by setting up the combined support one 1 with the first support leg 7, the second support leg 8, the V-shaped limit sleeve 9, the support shaft 10 and the connection reinforcement plate 11, and the combined support leg two 2, and by setting that the seat plate 3 is rotatably connected to the second support leg 8 through the second rotating shaft 15, the seat plate 3 is rotatably connected to the backrest 4 through the third rotating shaft 16, and the backrest 4 is rotatably connected to the first handle 5 and the second handle 6 through the fourth rotating shaft 17 respectively, the folding function can be realized, and the convenience of folding and unfolding can be improved. By setting the locking bolt 18, it can be locked during the long-term use of the seat, further improving the overall stability; by setting the first handle 5 and the second handle 6 with the handle body 19 and the limit connecting plate 20, and by setting the strip-shaped groove 21, the first limit hook 22, the second limit hook 23 and the limit strip 24, the angle of the backrest 4 can be adjusted, improving the convenience of use.
