AI Technical Summary
Existing folding chairs suffer from insufficient structural stability, complex operation, and easily wobbling support legs that are difficult to fold synchronously.
It adopts a linkage, swing arm, slide bar system and synchronous rotation mechanism, and achieves smooth linkage of the support legs through hinge and sliding cooperation, ensuring the synchronicity and stability of the folding chair during unfolding and folding, and limits the sliding range through sliding sleeve and fixed sleeve.
It improves the ease of operation and stability of folding chairs, reduces storage space occupation, and enhances user comfort.

Abstract
Claims
1. A folding chair comprising a first support leg and a second support leg located on either side; characterised in that: Also includes: A first link and a second link, wherein one end of the first link is hinged to the upper end of the first support leg, one end of the second link is hinged to the upper end of the second support leg, and the other end of the first link is hinged to the other end of the second link; A first pendulum and a second pendulum, wherein the other end of the first pendulum is hinged to the other end of the second pendulum; A first slide bar and a second slide bar, wherein one end of the first slide bar is configured to slide up and down on a first support foot, and one end of the second slide bar is configured to slide up and down on a second support foot; The other end of the first slide bar is configured to be hinged to the first connecting rod, and the other end of the second slide bar is configured to be hinged to the second connecting rod; The middle part of the first slide bar is configured to be hinged to the first swing arm, and the middle part of the second slide bar is configured to be hinged to the second swing arm.
2. A folding chair according to claim 1, characterized in that The first and second support feet are provided with sliding sleeves that can slide up and down on their outer periphery, and the sliding sleeves are hinged to one end of the first and second sliding rods.
3. A folding chair according to claim 2, wherein, The first support foot and the second support foot are fixedly equipped with a fixing sleeve on their outer periphery. The sliding sleeve can abut against the fixing sleeve to restrict the sliding sleeve from continuing to slide upward.
4. A folding chair according to any one of claims 1-3, c h a r a c t e r i s e d in that The first slide bar is configured to rotate synchronously with the first slide bar and the first swing bar, and the second slide bar is configured to rotate synchronously with the second slide bar and the second swing bar, so that the first support foot and the second support foot can be combined or separated.
5. A folding chair according to claim 4, wherein, The first slide bar and the second slide bar are equipped with connecting pieces, which are configured to abut against the bottom of the first swing arm and the second swing arm, so that when the folding chair is folded up, the first support leg and the second support leg can remain in the same state and come together.
6. A folding chair according to claim 5, wherein, When the folding chair is unfolded, the first and second swing arms form an angle of not less than 180°. When the folding chair is folded, one end of the first and second swing arms can swing downward. The first and second support legs are configured to be vertical. When the folding chair is folded, the first and second support legs can be brought together while maintaining their vertical orientation.
7. A folding chair according to any of claims 1-3, 5, 6, characterized in that The first support leg and the second support leg are configured in a pair, located on the front and rear sides of the folding chair respectively. Each first support leg is equipped with a first swing arm on one side. When the folding chair is in the unfolded state, one end of the first swing arm can be located outside the first support leg.
8. A folding chair according to claim 7, wherein, It also includes a connecting rod, which is disposed between the two first support legs and the two second support legs.
9. A folding chair according to claim 8, wherein, It also includes handrails, which are configured to be able to flip up and down in the lateral direction relative to the connecting rod.
10. A folding chair according to claim 9, wherein, It also includes a backrest support rod disposed on the armrest, the backrest support rod being configured to be able to rotate up and down relative to the armrest in the forward and backward directions.
