[0035] The first connecting mechanism 002 includes two first folding rods 021 rotatably connected at their middle parts. One end of each first folding rod 021 is rotatably connected to the seat cushion support rod 013, and the other end is rotatably connected to the front support leg 011. That is, the two first folding rods 021 are X-shaped, so that the first folding rods 021 can be folded or unfolded.
[0036] The backrest assembly 003 includes two backrest rods 031 arranged side by side, and a backrest folding assembly 032 disposed on the two backrest rods 031 and used to move the two backrest rods 031 away from each other or close together; the backrest folding assembly 032 includes a first folding mechanism 321 located above and rotatably connected to the two backrest rods 031 at both ends, a second folding mechanism 322 located below and rotatably connected to the two backrest rods 031 at both ends, and a telescopic rod 323 disposed between the first folding mechanism 321 and the second folding mechanism 322 and used to move the middle of the first folding mechanism 321 and the middle of the second folding mechanism 322 close together or away from each other, and a limiting member 3233 disposed on the telescopic rod 323 to prevent the telescopic rod 323 from extending or shortening. The middle part of the first folding mechanism 321 moves upward to fold the first folding mechanism 321, and the middle part of the second folding mechanism 322 moves downward to fold the second folding mechanism 322. When the first folding mechanism 321 and the second folding mechanism 322 are folded, the two back-adhesive rods 031 move closer to each other, realizing the folding of the back-adhesive folding structure. Conversely, the middle part of the first folding mechanism 321 moves downward to unfold the first folding mechanism 321, and the middle part of the second folding mechanism 322 moves upward to unfold the second folding mechanism 322. When the first folding mechanism 321 and the second folding mechanism 322 are unfolded, the two back-adhesive rods 031 move further apart, realizing the opening of the back-adhesive folding structure. After opening, the length of the telescopic rod 323 is limited by the limiting member 3233, which can prevent the first folding mechanism 321 and the second folding mechanism 322 from folding on their own. When the first folding mechanism 321 or the second folding mechanism 322 is unfolded or folded, both ends rotate with the back-adhesive rods 031. The backrest assembly 003 is equipped with a first folding mechanism 321, a second folding mechanism 322, and a telescopic rod 323. When the folding chair is unfolded, the first folding mechanism 321, the second folding mechanism 322, and the telescopic rod 323 form an "I" shape, which can support flexible fabrics such as Oxford cloth, prevent collapse, and further improve the experience of the folding recliner.
[0037] The first folding mechanism 321 comprises a first hinged seat 3211, two first rotating rods 3212 arranged between the first hinged seat 3211 and the backrest rod 031, one end of the first rotating rod 3212 being rotatably connected with the first hinged seat 3211, and the other end being rotatably connected with the backrest rod 031; when the first rotating rod 3212 rotates upward relative to the backrest rod 031, the first hinged seat 3211 moves upward relative, thereby realizing folding of the first folding mechanism 321; conversely, when the first rotating rod 3212 rotates downward relative to the backrest rod 031, the first hinged seat 3211 moves downward relative, thereby realizing unfolding of the first folding mechanism 321.
[0038] The second folding mechanism 322 comprises a second hinged seat 3221, two second rotating rods 3222 arranged between the second hinged seat 3221 and the backrest rod 031, one end of the second rotating rod 3222 being rotatably connected with the second hinged seat 3221, and the other end being rotatably connected with the backrest rod 031; when the second rotating rod 3222 rotates downward relative to the backrest rod 031, the first hinged seat 3211 moves downward relative, thereby realizing folding of the second folding mechanism 322; conversely, when the second rotating rod 3222 rotates upward relative to the backrest rod 031, the second hinged seat 3221 moves upward relative, thereby realizing unfolding of the second folding mechanism 322.
[0039] The telescopic rod 323 comprises a first connecting rod 3231 arranged above the first folding mechanism 321, a second connecting rod 3232 arranged inside the first connecting rod 3231 at one end and above the second folding mechanism 322 at the other end, and the end of the second connecting rod 3232 inside the first connecting rod 3231 being movably connected with the first connecting rod 3231. One end of the first connecting rod 3231 is sleeved with one end of the second connecting rod 3232, and the two are movably connected, so that the telescopic rod 323 is elongated or shortened when being folded or unfolded. The telescopic rod 323 further comprises a limiting piece 3233 arranged inside the second connecting rod 3232 for preventing the second connecting rod 3232 from moving inside the first connecting rod 3231. Specifically, when the backrest folding structure is unfolded, the telescopic rod 323 is shortened, and the limiting piece 3233 prevents the telescopic rod 323 from continuing to shorten or elongate.

When the back folding structure is unfolded, the limiting part 32332 can pass through the first through hole 32311 and the second through hole 32321, thereby playing a limiting role and preventing the second connecting rod 3232 from moving in the first connecting rod 3231. Specifically, before the telescopic rod 323 is shortened, the limiting part 32332 is located in the second through hole 32321 and abuts against the inner side wall of the first connecting rod 3231. When the back folding structure is unfolded, the telescopic rod 323 is shortened, the second connecting rod 3232 moves in the first connecting rod 3231 and drives the limiting piece 3233 to move. When reaching the first through hole 32311, the limiting part 32332 is pressed into the first through hole 32311 due to the elastic force of the elastic part 32331, i.e. under the action of elastic potential energy, thereby achieving limiting.
[0041] The first folding mechanism 321 further comprises a pressing part 32111 for pressing the limiting part 32332. Specifically, the pressing part 32111 is located on the first hinge seat 3211. When the limiting part 32332 is located in the first through hole 32311, the limiting part 32332 is pressed down by the pressing part 32111, so that the elastic part 32331 is compressed into the first through hole 32311. Since the end of the limiting part 32332 is a circular arc surface, only a point external force needs to be applied to elongate the telescopic rod 323, thereby releasing the limitation of the limiting piece 3233 and allowing the back folding structure to be folded. The pressing part 32111 is directly and integrally formed on the first hinge seat 3211, and the first hinge seat 3211 and the second hinge seat 3221 can both be plastic parts and can be integrally formed by injection molding process. The inner side of the pressing part 32111 is arc-shaped and matches the shape of the telescopic rod 323, and a step part 32112 is arranged on the inner side of the arc-shaped part corresponding to the limiting part 32332. The step part 32112 allows the limiting part 32332 to be pressed in better.
[0042] The first hinge seat 3211 is provided with a first groove for connecting the first rotating rod 3212 on both sides and a second groove for embedding the first connecting rod 3231 in the middle, the second hinge seat 3221 is provided with a third groove for connecting the second rotating rod 3222 on both sides and a fourth groove for embedding one end of the second connecting rod 3232 in the middle, specifically, the first rotating rod 3212 is embedded in the first groove or the second rotating rod 3222 is embedded in the third groove, then rotation is realized by rivet fixing or rotation is realized by screwing and locking with a nut, the connection between the other end of the first rotating rod 3212, the other end of the second rotating rod 3222 and the backrest rod 031 can also adopt rivet fixing to realize rotation or rotation is realized by screwing and locking with a nut, and the fixing mode of the first connecting rod 3231 embedded in the second groove and the fixing mode of the second connecting rod 3232 embedded in the fourth groove can refer to the above.
[0043] The rotating connection part of the utility model can adopt rivet direct riveting to realize rotation, or rotation connection is realized by screwing and connecting with a nut after screwing, or one or two U-shaped seats are adopted to realize rotation connection, and the specific fixing and mounting mode adopts the prior art, for example, a U-shaped seat is welded at the end of the backrest rod 031, one end of the cushion supporting rod 013 is embedded in the groove of the U-shaped seat, and then rivet or screw is used to realize the rotation connection between the cushion supporting rod 013 and the backrest rod 031, so that the folding or unfolding function is met.
[0044] In summary, the folding deck chair of the utility model realizes the adjustment of the backrest assembly by setting different gear grooves on the adjusting seat and corresponding different angle backrest assemblies when the rotating shaft is embedded in different gear grooves, so that the experience of the folding deck chair can be improved.
