Detailed Implementation

[0028] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0029] like Figures 1-6 As shown, the four-position folding chair provided in this embodiment has a support component including two chair rods 5 and two connecting rods 16 installed between the two chair rods 5. The opposite ends of the two connecting rods 16 are rotatably connected to a connecting buckle 8, and the opposite ends of the two connecting rods 16 are each connected to a telescopic rod 7. The telescopic rod 7 is used to increase the support strength. The lower parts of the two telescopic rods 7 are respectively connected to two staggered second connecting rods 9 through a second connecting buckle 12.

[0030] The adjustable support includes armrests 1 installed in the middle of the two chair posts 5. An adjustment plate 2 is installed at the lower part of the armrests 1 for adjusting the position. A support rod 3 is provided below the adjustment plate 2. The lower end of the support rod 3 is rotatably connected to a first connecting rod 6 via a foot buckle 15. The upper end of the support rod 3 is rotatably connected to a foot support rod 10 via a buckle. The foot support rod 10 and the support rod 3 provide bottom support, and at the same time, the telescopic rod 7 provides rearward support to the chair post 5, further improving the stability of the chair back.

[0031] The second connecting rod 9 is installed on the telescopic rod 7 by staggered installation. The telescopic rod 7 extends and retracts backward to form a clearance space, which can prevent the staggered second connecting rod 9 from pressing against the back when the folding chair is in use, thus affecting comfort. The first connecting rod 6 is installed upward to push against the folding rod 4. With the help of the support rod 10, the folding rod 4 can be parallel to the armrest 1 when it is opened. This allows the armrest 1 to be more evenly stressed. The two parts work together to increase the service life and reduce the stress on the armrest 1.

[0032] The upper ends of the chair rod 5 and the telescopic rod 7 are rotatably connected by the first connecting buckle 11. The lower end of the telescopic rod 7 is rotatably connected to the lower end of the support rod 10 by the third connecting buckle 13. The two second connecting rods 9 are rotatably connected in the middle, and the upper ends of the two second connecting rods 9 are rotatably connected to the two connecting rods 16 respectively. The lower end of the chair rod 5 is rotatably connected to one end of the folding rod 4 by the fourth connecting buckle 14. The other end of the folding rod 4 is rotatably connected to the upper end of the first connecting rod 6. The adjusting plate 2 is provided with four adjusting buckle slots 17. The upper end of the buckle seat is provided with a buckle plate that matches the buckle slot 17. The buckle slot 17 and the buckle plate can be adjusted in 4 positions. A handle is installed on the connecting buckle 8. The handle is used to pull up so that the connecting buckle 8 can be folded in conjunction with the connecting rod 16.

[0033] In summary, the four-position folding chair according to this embodiment has the following advantages:

[0034] 1. The chair can stand upright when folded, making it easy to place and store;

[0035] Second, by using the telescopic rod 7 in conjunction with the chair rod 5, the storage space is reduced, and the overall area occupied is decreased;

[0036] Third, the armrests of conventional folding chairs are prone to twisting under stress, while in this embodiment, the armrest 1 and folding rod 4 are on the same straight line when the chair is unfolded, so that the stress is evenly distributed. The armrest 1 will not be twisted due to uneven load, and the service life is longer.

[0037] Fourth, the staggered second connecting rod 9 is installed on the telescopic rod 7, which will not press against the back when people use it, making sitting more comfortable. The traditional cross rod is installed on the back of the chair, which is prone to pressing against the back and causing the fabric to loosen.
