A leisure chair primarily consists of a frame (legs), seat, backrest, and pedals. The lower portion of the frame is connected to a curved rocking foot that contacts the ground, creating a rocking motion when sitting or lying down.

[0003] In the process of implementing this application, the inventors discovered that the prior art has at least the following technical problems:

[0004] Most existing reclining chairs on the market have relatively simple functions, only having the function of swinging, and not taking into account the function of a normal seat in a static state. Therefore, it is urgent to develop an adjustment structure that improves the applicability of the reclining chair. Utility Model Content

The following description of the embodiments is merely to provide a better understanding of the present application by illustrating the examples of the present application.

[0028] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device. In the absence of further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or device comprising the element.

[0029] Most existing reclining chairs on the market have relatively simple functions, only having the function of swinging, and do not take into account the function of the normal seat in a static state. In order to solve the existing technical problems, the applicant has improved the structure of the chair chassis adjustment mechanism, and the embodiments of the present application are further described below.

[0030] In order to better understand this application, Figures 1 to 6 The embodiments of the present application are described.

[0031] Please refer to Figures 1-6 The present invention provides a chair chassis adjustment mechanism 1, wherein the chair chassis adjustment mechanism 1 includes a control rod 101, a guide member 102, a movable limit block 103, an elastic member 104, and a rocking piece 105. The guide member 102 has a guide hole 1021 and a guide groove 1022. One end of the control rod 101 has a bent portion 1011, and the bent portion 1011 is disposed in the guide hole 1021 and can move along the guide hole 1021. The movable limit block A guide block corresponding to the guide groove 1022 is provided at the bottom of 103, and the movable limit block 103 is movably connected to the guide member 102 through the guide block. A connecting member 106 is provided between the bent portion 1011 and the movable limit block 103. The bottom of one end of the shaking piece 105 is fixedly connected to the top of the elastic member 104, and the bottom of the other end of the shaking piece 105 has a protrusion 1051, and the protrusion 1051 can be engaged with the movable limit block 103;

[0032] The chair chassis adjustment mechanism 1 also includes a mounting plate 2 and a connecting shell 3. The mounting plate 2 is fixedly connected to the rocking plate 105. The connecting shell 3 is rotatably connected to the mounting plate 2. A limiting hole 301 is provided on one side of the connecting shell 3. The chair chassis adjustment mechanism 1 is arranged inside the connecting shell 3. The guide member 102 is fixedly provided on the connecting shell 3. One end of the control rod 101 extends to the outside of the connecting shell 3 through the limiting hole 301. The bottom of the elastic member 104 is fixedly connected to the connecting shell 3. The top of the rocking plate 105 is fixedly connected to the mounting plate 2.

[0033] In this embodiment, the control rod 101 can control the movement of the movable limit block 103 through the connecting piece 106. When the movable limit block 103 abuts against the convex portion 1051 of the rocking piece 105, the rocking piece 105 cannot swing. At this time, the movable limit block 103 and the rocking piece 105 are in the first state. When the position of the movable limit block 103 is misaligned with the position of the convex portion 1051, the movable limit block 103 and the rocking piece 105 are in the second state. The rocking piece 105 can swing under the external force. Specifically, if the movable limit block 103 and the rocking piece 105 are in the second state, the user adjusts the control rod 101 to move in the first direction, and adjusts the movable limit block 103 and the rocking piece 105 to enter the first state. If it is desired to call back to the second state, the user adjusts the control rod 101 to move in the second direction, and the guide hole 1021 is used to limit the moving direction of the control rod 101, thereby achieving the purpose of limiting the moving direction of the movable limit block 103 in the guide groove 1022.

[0034] Further, in some other embodiments of this application, please refer to Figure 1 and Figure 6 The chair chassis adjustment mechanism 1 also includes a limit member 107. The limit member 107 is in an inverted U shape. One end of the limit member 107 is fixedly connected to the guide member 102, and the other end is fixedly connected to the bottom of the elastic member 104. The limit member 107 is used to limit the control rod 101. It can be understood that the inverted U-shaped limit member 107 can limit the movement of the control rod 101 in the height direction, further limit the moving direction of the control rod 101, and enable the control rod 101 to be more accurately controlled.

[0035] Furthermore, in some other embodiments of the present application, the elastic member 104 is a spring, and the number of the elastic members 104 is two. It can be understood that the number of the elastic members 104 can also be or , and the elastic members 104 are respectively arranged at the bottom of one end of the shaking piece 105.

[0036] It should be noted that if Figure 1As shown, the control rod 101 extends from the inside of the connecting shell 3 to the outside thereof through the limiting hole 301 on the connecting shell 3, so that the user can control the position movement of the movable limit block 103 through the control rod 101, and finally realize the function adjustment. In addition, the control rod 101 has a bending portion 1011, and the bending portion 1011 is arranged in the guide hole 1021, which limits the moving direction of the bending portion 1011, so that the control rod 101 controls the movable limit block 103 to move on a fixed path, so that the control rod 101 can achieve more precise control.

[0037] Please refer to the figure. In some other embodiments of the present application, the part of the control rod 101 located in the limiting hole 301 is rotatably connected to the connecting shell 3. Such a design can make it more convenient for the user to operate the control rod 101 and save the user more effort.

[0038] Please continue to refer to Figure 4-Figure 6 In some other embodiments of the present application, a fixing rod 302 is provided between the two sides of the connecting shell 3, and a rotating member 303 is sleeved on both ends of the fixing rod 302. The bottom of the mounting plate 2 is connected to the rotating member 303, and the mounting plate 2 is rotatable with the connecting shell 3 through the rotating member 303. The movable limit member 107 and the rocking piece 105 have two states. When the movable limit member 107 and the rocking piece 105 are misaligned, it is the first state; when the movable limit member 107 and the rocking piece 105 are engaged, it is the second state.

[0039] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprises" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article or device. In the absence of further limitations, an element defined by the sentence "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device that includes the element.
