[0049] The present application will be further described in detail below with reference to the accompanying drawings.

[0050] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0051] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the specification of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items. Example 1

[0052] Figure 1 A folding support leg structure is shown, including a first connector 11, a second connector 12, and a support leg 14. The first connector 11 is connected to the second connector 12, and the support leg 14 is connected to the second connector 12. In this embodiment, the support leg 14 has a folded state and an unfolded state. In the folded state, the first connector 11 can rotate relative to the second connector 12, causing the support leg 14 to flip with the second connector 12, thereby achieving folding. In the unfolded state, the first connector 11 and the second connector 12 are locked together, and the support leg 14 remains upright under the locking of the second connector 12 to provide support.

[0053] See also Figure 2 and Figure 3The folding support leg structure 10 also includes a latch 13, which can slide relative to the first connector 11 and the second connector 12. The latch 13 includes a generally elongated main body section 131, a lever 132 is provided on the outer peripheral wall of the main body section 131, and a receiving groove 133 with one side opening is provided at one end of the main body section 131 opposite to the lever 132.

[0054] The first connector 11 has a locking hole 113 and a first pivot seat 112 on one side adjacent to the locking hole 113. The second connector 12 has a guide hole 122, the main body section 131 is slidably connected in the guide hole 122, and the second connector 12 also has a guide opening 123 communicating with the guide hole 122. The lever 132 is slidably connected in the guide opening 123, and the latch 13 is connected by the cooperation between the lever 132 and the second connector 12.

[0055] The second connector 12 also has a second pivot seat 121. The first pivot seat 112 and the second pivot seat 121 are rotatably connected by a rotating shaft 16, thereby realizing the rotatable connection between the first connector 11 and the second connector 12.

[0056] The outrigger 14 includes a rod 141 and a connected support base 142. One end of the rod 141 extends into the guide hole 122 of the second connector 12 and is connected to the second connector 12. The other end of the rod 141 is provided with a ball head 143. The support base 142 has a cavity 1421. The ball head 143 is partially received in the cavity 1421 and rotates in the cavity 1421. The rod 141 is connected to the support base 142 through a ball joint structure, which can better adapt to the contact between the support base 142 and the ground under different terrains.

[0057] Combination Figure 3 The latch 13 also includes a first connecting post 135, a second connecting post 136, and an elastic member 15. A guide channel 134 is also provided on the main body section 131. The first connecting post 135 passes through the guide channel 134 and can slide relative to the guide channel 134. At the same time, the first connecting post 135 also passes through the second connecting member 12 and the rod 141 to realize the connection between the second connecting member 12 and the rod 141.

[0058] The second connecting post 136 is also inserted through the rod 141. The elastic member 15 is housed in the receiving groove 133, and the two ends of the elastic member 15 abut against the groove wall of the receiving groove 133 and the second connecting post 136, respectively. While limiting the elastic member 15 to be located in the receiving groove 133, the elastic member 15 can also force the main body segment 131 to always have a tendency to move towards the locking hole 113.

[0059] In this embodiment, the latch 13 has a first state and a second state. In the first state, the end of the main body segment 131 extends into the locking hole 113, and the first connector 11 and the second connector 12 are locked together. In the second state, the end of the latch 13 disengages from the locking hole 113, and the second connector 12 can rotate relative to the first connector 11. In the first state, the corresponding support leg 14 is in an unfolded state, and in the second state, the corresponding support leg 14 can be rotated to a folded state.

[0060] Combination Figure 5 When the folding support leg structure 10 folds, it is only necessary to press the lever 132 and slide it a certain distance in the guide opening 123, so that part of the main body section 131 disengages from the locking hole 113, thereby unlocking the rotational lock between the first connector 11 and the second connector 12. At this time, the support leg 14 can fold with the rotation of the second connector 12. In order to limit the maximum angle of the support leg 14 to flip and fold, the first pivot seat 112 also has a limiting block 1121. When the second pivot seat 121 abuts against the limiting block 1121, the support leg 14 is at the maximum folding angle.

[0061] Conversely, when assembly is required, simply flip the support leg 14 and press the lever 132 to prevent the end of the main body segment 131 from interfering with the first connector 11. Then release the lever 132, and the main body segment 131 will be pushed into the locking hole 113 by the elastic member 15 to achieve locking with the first connector 11.

[0062] In another embodiment, to make unlocking smoother, two levers 132 are symmetrically arranged on the outer wall of the main body segment 131. When unlocking, two fingers can simultaneously press and slide the two levers 132. Example 2

[0063] See also Figure 6 and Figure 7 A folding recliner includes multiple folding leg structures 10 as described in Embodiment 1, multiple longitudinal connecting tubes 20, multiple support rods 30, and a fabric cover 40. The first connecting member 11 also has multiple inserts 111. Both ends of the longitudinal connecting tubes 20 are engaged in the inserts 111 of two adjacent first connecting members 11. One end of each support rod 30 is also engaged in one of the inserts 111 of the first connecting member 11. The fabric cover 40 is connected to the multiple support rods 30.

[0064] In this embodiment, four longitudinal connecting pipes 20 are provided and enclosed in a rectangle to improve the stability of the support, and each first connecting member 11 has three inserts 111.

[0065] In addition, in this embodiment, both the outrigger 14 and the support rod 30 are telescopic structures. For example, the structure can be designed as described in the patent announcement number CN221060087U, where the inner and outer rods 141 can slide against each other and are limited by elastic locking protrusions. Of course, other telescopic structures are also possible, but they will not be described in detail here.

[0066] See also Figure 8 and Figure 9 When this folding recliner is folded for storage, each folding leg structure 10 can be folded inward, significantly reducing the vertical height and increasing the vertical storage space. Simultaneously, it can also function as a reclining bed; by folding down the two legs 14 on one side, the fabric cover 40 is placed in a near-horizontal position. Provided the structural strength design of the first connecting piece 11 and the second connecting piece 12 is appropriate, for example, by using high-strength and bending-resistant materials, a reclining bed-like function can be achieved.

[0067] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
