[0041] Side support rod 16 and diagonal support rod 6: The side support rod 16 and diagonal support rod 6 work together, through a sliding sleeve and hinge point, to achieve the function of supporting and rotating the chair during the folding process. The diagonal support rod 6 is fixed to the backrest upright 1 and, through cooperation with the side support rod 16, enables the chair to be folded quickly.

[0042] Fork 5: The combination of cross-overlapping and hinged positions in fork 5 makes the entire folding process smooth and efficient, ensuring that the chair can be folded quickly and remain stable.

[0043] Adjustment component 12: The adjustment component includes a press button 12 and a friction element 13, which can adjust the height of the telescopic rod 7 and change the chair height and sitting angle as needed.

[0044] Spring system 8: The telescopic spring 8 is located inside the backrest column 1 and the support column 2, and is used for elastic support and to ensure the stability of the telescopic rod 7 during use.

[0045] II. Folding Process

[0046] The folding process mainly consists of the following steps:

[0047] The first connector 3 and the second connector 4 slide: The first connector 3 cooperates with the diagonal brace 6. When folding, the first connector 3 slides along the backrest column 1, causing the upper end of the diagonal brace 6 to slide and rotate through the sliding sleeve. The third connector 15, the support column 2, and the limiting sleeve 19 will all slide upward, so that the backrest and seat cushion of the chair are gradually folded up.

[0048] The coordination between the diagonal brace and the side brace: The lower end of the diagonal brace 6 is fixed to the backrest column 1, keeping the support point stationary. The side brace 16 rotates during folding by engaging with the hinge point of the third connector 15, changing the angle between the chair back and the seat, and gradually folding the chair together.

[0049] The cross-operation of the forks: During folding, the forks 5 overlap and hinge at the intersection, working together to stably fold all parts of the chair. The cooperation of the forks ensures smooth and rapid folding.

[0050] Final folding complete: When all parts are folded, the backrest column 1, the leg support column 2, and other parts will be tightly packed together, and the chair will be stored in its smallest volume for easy carrying and storage.

[0051] III. Development Process

[0052] The unfolding process is similar to the folding process, achieved through the reverse operation:

[0053] Adjusting the height of the telescopic rod: By pressing the button 12 of the adjustment component, the telescopic rod 7 extends downwards to adjust the chair height. At this time, the telescopic rod 7 engages with the threaded sleeve 9 and the ball head 10, and the support foot 11 provides support, ensuring the stability of the telescopic rod.

[0054] Unlocking the folding mechanism: Through the cooperation of the fork 5 and the side support 16, the chair gradually unfolds from its folded state. The fork 5 works in conjunction with the diagonal support 6 to return the chair to its normal use state.

[0055] Stable support: When the chair is fully extended, the backrest column 1 and the leg support column 2 stably support the entire chair through the telescopic rod 7, ensuring the chair's sturdiness and stability during use.

[0056] Example 1:

[0057] A fully folding outdoor chair, during the folding process, the third connector 15 and the first connector 3 of the support column 2 slide upwards simultaneously; at the same time, the upper end of the diagonal support rod 6 slides along the side support rod 16 through the sliding sleeve and rotates, and the backrest and seat gradually fold. When the third connector 15 slides upwards to its final position, the limiting sleeve 19 disengages from the locking support of the second connector 4, and all parts are tightly closed, forming a folded state.

[0058] When unfolded, the user can adjust the height of the telescopic rod 7 to adjust the seating angle of the chair, and easily unfold the chair and restore it to normal use through the cooperation of the fork rod 5 and the diagonal brace 6.

[0059] The outdoor chair in this embodiment has a compact structure, folds quickly, and has good stability, making it suitable for use in outdoor activities, especially for fishing, camping, and other occasions.

[0060] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
