Due to their convenience, more and more families now own folding chairs. However, most existing folding chairs are not suitable for both home and outdoor use at the same time, and the comfort of users during use needs to be improved. Therefore, there is a need for an outdoor folding chair with an adjustable backrest angle.

[0003] Currently, Chinese patent CN221931614U discloses an outdoor folding chair, including an X-shaped cross-hinged left and right frame. A seat cushion is fixed to the upper ends of the left and right frames. Unlike existing technologies, the upper ends of the left and right frames are hinged to H-shaped left and right armrest / backrest frames. A backrest fabric is fixed to the left and right armrest / backrest frames. After the backrest fabric is removed from the left and / or right armrest / backrest frames, the left and right armrest / backrest frames can be folded outwards and abut against the left and right frames respectively. Compared to existing technologies, the total height of this invention after folding is only the height of the left and right frames, and the thickest part is four times the thickness of the vertical strips, making it very small and easy to fold.

[0004] However, when using the above-mentioned device, it is not convenient to adjust the back, and the user needs to maintain the same angle when sitting, which reduces the user's comfort.

[0005] Therefore, this utility model provides an outdoor folding chair with an adjustable backrest angle. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-6 An outdoor folding chair with an adjustable backrest angle includes a seat cushion 1, a backrest 2 on one side of the seat cushion 1, a folding mechanism at the bottom of the seat cushion 1, and an adjustment mechanism at the bottom of the backrest 2. The adjustment mechanism includes two fixed plates 3, which are fixed to the side of the seat cushion 1. One side of the fixed plate 3 is rotatably connected to the adjustment shaft 4 via a bearing. The adjustment shaft 4 is fixed to the bottom of the backrest 2. The end of the adjustment shaft 4 is fixedly connected to a rotating plate 5, which rotates by being limited by a limiting member.

[0021] Specifically, after the limiting rod 6 loses its limiting effect on the rotating plate 5, the rotating plate 5 can be rotated. The rotation of the rotating plate 5 causes the adjusting shaft 4 to rotate, which in turn causes the backrest 2 to rotate, thus adjusting the angle between the backrest 2 and the seat cushion 1. After the angle adjustment is completed, the limiting component can fix the rotating plate 5 in a stable position. Therefore, the back of the chair can be adjusted to improve the user's comfort.

[0022] As a further improvement of this utility model, the limiting component includes a limiting rod 6, which intersects with the fixed plate 3. A plurality of limiting ports 7 are opened on one side of the rotating plate 5. The limiting rod 6 and the inner wall of the limiting port 7 form a sliding fit. A limiting spring 8 is fixedly connected to the bottom of the limiting rod 6, and the end of the limiting spring 8 is fixed to the side of the fixed plate 3.

[0023] Specifically, by separating the limiting rod 6 from the inner wall of the limiting port 7, the limiting spring 8 is compressed. After the limiting rod 6 loses its limiting effect on the rotating plate 5, the rotating plate 5 can be rotated. After the angle adjustment is completed, the limiting rod 6 can rotate into the limiting port 7. Combined with the pressure of the limiting spring 8, the rotating plate 5 can be fixed and stable.

[0024] As a further improvement of this utility model, the folding mechanism includes two rotating frames 9, which are U-shaped. The bottom of the cushion 1 has two rotating grooves 11. The inner wall of the rotating groove 11 is rotatably connected to the rotating shaft 10 through the bearing. The rotating shaft 10 is fixed to the rotating frame 9.

[0025] Specifically, the rotating frame 9, in conjunction with the rotation of the rotating shaft 10 within the rotating groove 11, allows the rotating frame 9 to rotate into the rotating groove 11, enabling a folding operation.

[0026] As a further improvement of this utility model, the ground contact part of the rotating frame 9 has an arc-shaped structure.

[0027] Specifically, the rotating frame 9, which has an arc-shaped structure, makes its contact surface with the ground curved, thus reducing sharp friction.

[0028] As a further improvement of this utility model, the inner wall of the contact surface between the rotating groove 11 and the rotating frame 9 after they are unfolded has an arc-shaped structure.

[0029] Specifically, the inner wall of the contact surface between the arc-shaped rotating groove 11 and the unfolded rotating frame 9 can prevent sharp corners from damaging the rotating frame 9.

[0030] As a further improvement of this utility model, a first magnetic block 12 is fixedly connected to both sides of one side of the rotating frame 9, and a second magnetic block 13 is fixedly connected to the inner wall of the rotating groove 11. The first magnetic block 12 and the second magnetic block 13 are magnetically connected.

[0031] Specifically, by magnetically connecting and fixing the first magnetic block 12 and the second magnetic block 13, the limiting rod 6 loses its limiting effect on the rotating plate 5.

[0032] As a further improvement of this utility model, an elastic band 14 is fixedly connected to the bottom of the seat cushion 1, and a restraint ring 15 is fixedly connected to the end of the elastic band 14. A nail hook 16 is fixedly connected to one side of the backrest 2, and the restraint ring 15 is hooked to the nail hook 16.

[0033] Specifically, the folding operation can be completed by hooking the hook 16 with the restraint ring 15. When using the chair, the hook 16 can also be used to hang bags, etc., increasing the chair's practicality.

[0034] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0035] The working principle of this utility model is as follows: When in use, pulling the rotating frame 9 allows the rotating frame 9 to rotate in conjunction with the rotating shaft 10 within the inner wall of the rotating groove 11. The rotation of the rotating frame 9 causes the first magnetic block 12 and the second magnetic block 13 to separate. After the rotating frame 9 is in place, the limiting rod 6 can separate from the inner wall of the limiting port 7. At this time, the limiting spring 8 is compressed. After the limiting rod 6 loses its limiting effect on the rotating plate 5, the rotating plate 5 can be rotated. The rotation of the rotating plate 5 causes the adjusting shaft 4 to rotate, which in turn causes the backrest 2 to rotate, thus adjusting the angle between the backrest 2 and the seat cushion 1. After the angle adjustment is completed, the limiting rod 6 can rotate into the limiting port 7. Combined with the pressure of the limiting spring 8, the rotating plate 5 can be fixed and stabilized. Therefore, the back of the chair can be adjusted to improve the user's comfort. When folding the rotating frame 9, lift the seat cushion 1 and rotate the rotating frame 9. In conjunction with the rotation of the rotating shaft 10 in the rotating groove 11, the rotation of the rotating shaft 10 allows the rotating frame 9 to rotate into the rotating groove 11, and the first magnetic block 12 and the second magnetic block 13 are magnetically connected and fixed, so that the limiting rod 6 loses its limiting effect on the rotating plate 5, and the backrest 2 and seat cushion 1 are folded. Finally, hook the restraint ring 15 onto the nail hook 16 to complete the folding operation. When using the chair, the nail hook 16 can also be used to hang bags, etc., increasing the practicality of the chair.
