[0033] This embodiment discloses an outdoor adjustable backrest folding chair. By configuring the support assembly 1 and the base folding bracket assembly 2, when the horizontal support part 12 in the support assembly 1 is damaged, the damaged portion of the horizontal support part 12 and the support bottom 11 is torn apart along the notch 15, and the back support part 13 is detached from the backrest bracket seat 23 and installed on the front connector 221. This allows the back support part 13, used for back support, to replace the horizontal support part 12 for temporary horizontal support of the user. This avoids the predicament of the folding chair being unusable after the horizontal support part 12 and the support bottom 11 are suddenly damaged in the wild, thus improving the folding chair's ability to cope with emergencies. (Refer to...) Figures 1-8 It mainly includes a foldable base bracket assembly 2 and a support assembly 1 that is detachably installed on the base bracket assembly 2. The support assembly 1 and the base bracket assembly 2 are connected by a first connecting assembly 4 and a second connecting assembly 5 provided on the support assembly 1, and a rotating connecting assembly 3 installed on the base bracket assembly 2.

[0034] Depend on Figure 2 , Figure 5 as well as Figure 8 As shown, the base folding bracket assembly 2 includes a foldable bottom bracket 21 and multiple connecting blocks 22 fixed on the bottom bracket 21. The connecting blocks 22 include a front connector 221 at the front end and a rear connector 222 at the rear end. The rear connector 222 has a through hole. The uppermost ends of both sides of the bottom bracket 21 are fixedly connected to a backrest bracket seat 23. A backrest support frame 24 is rotatably connected to the end of the backrest bracket seat 23 away from the bottom bracket 21. The backrest support frame 24 and the backrest bracket seat 23 are connected by a torsion spring 6. The backrest support frame 24 is leveled by setting the torsion spring 6. When the user leans on the backrest support frame 24, the backrest support frame 24 is rotated, so that the angle between the backrest support frame 24 and the backrest bracket seat 23 can be adjusted according to the user's degree of leaning. When the backrest support frame 24 is not under force, the rebound of the torsion spring 6 drives the backrest support frame 24 to rotate back to its original position.

[0035] By providing the torsion spring 6 for connecting the backrest support seat 23 and the backrest support frame 24, when users of different weights lean against the backrest support frame 24 in different postures, the backrest support frame 24 rotates to adjust the support angle of the folding chair back, thereby adapting to the different users' choices of backrest angle.

[0036] Depend on Figure 4 It is known that the rotating connection assembly 3 includes a bottom barrel 31, the front end connector 221 is rotatably connected to the corresponding bottom barrel 31, the uppermost end of the chair back support frame 24 is rotatably connected to the corresponding bottom barrel 31, the bottom barrel 31 has a limiting groove 34 inside, and a plurality of arc-shaped blocking parts 32 and grooves 33 are arranged sequentially along the axial direction of the limiting grooves 34, the upper surface of the grooves 33 is flush with the upper surface of the bottom barrel 31.

[0037] Depend on Figure 1 and Figure 7 It is understood that the support assembly 1 includes a horizontal support part 12 arranged horizontally on the base folding bracket assembly 2 for horizontal support, and a back support part 13 installed on the back support frame 24 for support.

This not only allows for the replacement of damaged support components 1, extending the service life of the folding chair, but also allows users to choose a suitable style of support component 1 to install on the base folding bracket assembly 2 according to their different preferences, thereby improving the customer's user experience.

[0041] The working principle of this utility model of an outdoor adjustable backrest folding chair:

[0042] When it is necessary to replace the damaged horizontal support 12 and the support bottom 11 with the back support 13;

[0043] First, the bottom barrel 31 is rotated by an external force. The rotation of the bottom barrel 31 causes the arc-shaped blocking member 32 to rotate until it no longer obstructs the arc-shaped member 42. Then, the ring member 41 is moved away from the interior of the bottom barrel 31 by an external force.

[0044] Secondly, the notch 15 is torn open by external force. Then, the back support 13 is rotated and laid flat to a horizontal state. Then, the ring 41 is moved into the bottom barrel 31 by external force. At the same time, the movement of the ring 41 causes the circular stop 43 to move and engage in the groove 33. Meanwhile, the arc-shaped part 42 enters the limiting groove 34. Then, the bottom barrel 31 is rotated to cause the arc-shaped blocking part 32 to rotate and obstruct the arc-shaped part 42.

[0045] When it is necessary to disassemble the entire support assembly 1;

[0046] First, the ring 41 is removed from the corresponding bottom barrel 31 by external force, as described above, and will not be repeated here.

[0047] Secondly, by using external force to cause the elastic groove on the clip 51 to contract and reduce the diameter of the clip 51, it disengages from the through hole on the rear connector 222, thus completing the disassembly of the second connecting component 5 and the disassembly of the entire support component 1.
