When an element is referred to as being "connected to" another element, it can be directly connected to or indirectly connected to the other element.

[0028] In the description of this utility model, it should be noted that the terms "center," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "multiple" means two or more, unless otherwise explicitly specified. "Several" means one or more, unless otherwise explicitly specified.

[0029] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit its scope. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the present utility model.

[0031] Example 1: See Figures 1 to 7A connecting joint used on a folding recliner includes a first joint 1 and a second joint 2. The connecting ends of the first joint 1 and the second joint 2 are respectively used to receive an adjustment body. The first joint 1 and the second joint 2 are connected by a connecting shaft 3, and the relative rotation range between the first joint 1 and the second joint 2 is 0° to 180°. This configuration is not only simple in structure and easy to manufacture, but also conducive to the folding and unfolding effect of connecting the seat and footrest. At the same time, the connecting ends of the first joint 1 and the second joint 2 are respectively used to receive an adjustment body, which facilitates the installation of the folding chair, reduces the difficulty of installation, reduces direct wear on the seat and footrest, and extends the service life.

[0032] Example 2: This can be explained based on Example 1, such as... Figures 1 to 7 As shown, the first joint 1 includes a first connecting end 11 for receiving the external adjustment body and an inner connecting part 12 integrally formed with the first connecting end 11. The second joint 2 includes a second connecting end 21 for receiving the external adjustment body and an outer connecting part 22 integrally formed with the second connecting end 21. The inner connecting part 12 is inserted into the outer connecting part 22, and both the inner connecting part 12 and the outer connecting part 22 have openings on the same side. The inner connecting part 12 and the outer connecting part 22 are connected by a connecting shaft 3. This facilitates the inner connecting part 12 and the outer connecting part 22 to rotate from 0° to 180° around the connecting shaft 3 as a fulcrum.

[0033] Among them, such as Figures 1 to 7 As shown, the inner connecting part 12 uses an even number of inner connecting blocks, while the outer connecting part 22 uses an odd number of outer connecting blocks. The inner connecting blocks are sequentially inserted into the space between the outer connecting blocks, and the inner connecting blocks and outer connecting blocks are connected together by the connecting shaft 3. This arrangement is reasonable, easy to manufacture, and allows for mutual rotation. In this embodiment, two inner connecting blocks and three outer connecting blocks are used. The two inner connecting blocks are respectively inserted into the space between the adjacent outer connecting blocks. This arrangement is reasonable, easy to implement, more stable and reliable in operation, and better meets the usage requirements.

[0034] Among them, such as Figures 1 to 7As shown, the first connecting end 11 has a first mounting groove for the external receiving and adjusting body, which is arranged along the length of the first connecting end 11. The first connecting end 11 also has a first fixing hole 111, in which a first fixing member is installed. The first fixing member securely connects the external receiving and adjusting body to the first connecting end 11. The second connecting end 21 has a second mounting groove for the external receiving and adjusting body, which is arranged along the length of the second connecting end 21. The first connecting end 11 also has a second fixing hole 211, in which a second fixing member is installed. The second fixing member securely connects the external receiving and adjusting body to the second connecting end 21. This arrangement is reasonable and facilitates the installation of the external receiving and adjusting body. In this embodiment, two fixing holes 111 and 211 are used, corresponding to two first and two fixing members, resulting in a more stable and reliable connection. Specifically, the first and second fixing members are screws or bolts, facilitating installation and disassembly. It should also be noted that both the first and second mounting slots use oblong holes, which is more conducive to the installation with the external receiving adjustment body.

[0035] All standard parts used in this application can be purchased from the market, and the specific connection methods of each part adopt conventional methods such as bolts and rivets that are mature in the existing technology, which will not be described in detail here.

[0036] It should be noted that although the above embodiments have been described herein, this does not limit the scope of patent protection for this utility model. Therefore, any changes and modifications made to the embodiments described herein based on the innovative concept of this utility model, or equivalent structural or procedural transformations made using the content of this utility model's specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields, are all included within the scope of protection of this utility model patent.
