[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] It should be noted that the terms “vertical”, “horizontal”, “up”, “down”, “left”, “right” and similar expressions used in this document are only for illustrative purposes and do not represent the only implementation method.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by technicians in the technical field of the present invention; the terms used in the specification of the present invention are only for the purpose of describing specific implementation methods and are not intended to limit the present invention; the term "and / or" used herein includes any and all combinations of one or more related listed items.

[0027] like Figure 1 and Figure 2 As shown, the utility model provides an adjustable sofa leisure chair, including a support base 1, adjustment structures 2 are provided on both sides of the support base 1, a support shell 11 is provided on the support base 1 and is sleeved on the outside of the adjustment structure 2, symmetrically distributed armrests 12 are connected above the support shell 11, an arc-shaped buffer pad 13 is provided between the armrests 12 and is placed on the support base 1, a second rotating shaft 22 is connected to a foot plate 14 at one end away from the support base 1, the adjustment structure 2 includes a first rotating shaft 21 placed in the direction of one end of the support base 1, a second rotating shaft 22 placed in the direction of the other end of the support base 1, an adjustment rotating shaft 23 is provided between the first rotating shaft 21 and the second rotating shaft 22, the other end of the buffer pad 13 is connected to a backing plate 24 connected to the first rotating shaft 21, the first rotating shaft 21 is placed on the inner side of the buffer pad 13, and the first rotating shaft 21 and the second rotating shaft 22 are respectively provided with a rotating shaft 25 running through themselves.

[0028] In this embodiment, a support base 1 with an adjustment structure 2 is provided, and the adjustment shaft 23 in the support base 1 is adjusted to drive the first shaft 21 and the second shaft 22 to rotate respectively, thereby adjusting the angles of the back panel and the foot panel of the sofa chair, which can support and adjust the user in two directions, thereby increasing comfort and higher adaptability.

[0029] like Figure 3 and Figure 4As shown, both ends of the first rotating shaft 21 are provided with first transmission wheels 211 penetrated by the rotating shaft 25, both ends of the second rotating shaft 22 are provided with second transmission wheels 221 penetrated by the rotating shaft 25, the adjusting rotating shaft 23 is provided with a second adjusting wheel 222 penetrated by the adjusting rotating shaft 23, the outside of the second adjusting wheel 222 is provided with a first adjusting wheel 212 also penetrated by the adjusting rotating shaft 23, the first adjusting wheel 212 and the first transmission wheel 211, the second adjusting wheel 222 and the second transmission wheel 221 are all connected by corresponding meshing conveyor belts 26, the diameter of the first transmission wheel 211 is larger than the diameter of the first adjusting wheel 212, and the diameter of the second transmission wheel 221 is larger than the diameter of the second adjusting wheel 222.

[0030] In this embodiment, when the adjustment shaft 23 is rotated for adjustment, the first adjustment wheel 212 and the second adjustment wheel 222 are driven to rotate, and the first transmission wheel 211 and the second transmission wheel 222 at the corresponding positions are driven by the conveyor belt 26, thereby driving the first rotating shaft 21 and the second rotating shaft 22 to rotate, thereby driving the back plate 24 and the foot plate 14 to adjust the adaptive angle.

[0031] It should be noted that the exterior of the utility model is covered with a standard leather cover and fillers to enhance comfort. The attached drawings show only the basic framework. If the rotation angle needs to be limited, it is only necessary to increase the length of one tooth on the transmission gear and set a blocking block corresponding to its length on the same plane. Because it is a commonly used means and technology in the prior art, it will not be described in detail in this article.

[0032] When in use, sit on the sofa leisure chair and adjust the angles of the foot plate 14 and the back plate to make yourself feel comfortable. If the angle of the sofa leisure chair needs to be adjusted, start rotating from the adjusting shaft 23 at one end of the support base 1 to drive the first and second shafts to rotate, so that the angles of the back plate 24 and the foot plate 14 change to meet personal needs; if the rotation angle needs to be limited, just increase the length of one gear and set a blocking block on the same plane; when the use is finished, put the sofa leisure chair back to its original position, and strengthen or replace the padding and leather cover as needed to enhance comfort.

[0033] Although the present invention has been disclosed as above in terms of preferred embodiments, it is not intended to limit the present invention.
