[0031] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0032] Please refer to Figures 1 to 6 As shown, an embodiment of the present invention provides a round-leg plug-in seat, comprising: a seat surface 1, adjustable chair legs 2 installed at the four corners of the bottom of the seat surface 1, an adjustment component 201 for adjusting the chair legs 2 installed on the chair legs 2, and an angle-adjustable backrest 3 provided at the top of the seat surface 1.

[0033] By adopting the above technical solution, not only can the height of the chair legs 2 be easily adjusted by setting the adjustment component 201, so as to be suitable for users of different heights, but also the backrest angle of the user's seat can be adjusted according to the user's seat, thereby improving the user's comfort and thus improving the flexibility of the use of the chair of this utility model.

[0034] To facilitate the height adjustment of the chair legs 2, in this embodiment: the adjustment component 201 includes a connecting sleeve 2011, both ends of the connecting sleeve 2011 are provided with connecting grooves 2012 that match the chair legs 2, the side of the connecting groove 2012 is provided with an abutment component 2013 for positioning and fixing the connecting sleeve 2011, and the side of the connecting sleeve 2011 and the position corresponding to the abutment component 2013 are provided with a lever handle 2014 for squeezing the abutment component 2013.

[0035] To facilitate fixing the connecting sleeve 2011 to the chair leg 2, in this embodiment: the abutment component 2013 includes an arc-shaped abutment plate 20131, a connecting spring 20132 is fixedly connected to the side of the arc-shaped abutment plate 20131, and the other end of the connecting spring 20132 is fixedly connected to the side of the inner wall of the connecting groove 2012. A force-bearing block 20133 that cooperates with the lever 2014 is fixedly connected to the side of the arc-shaped abutment plate 20131 at the position corresponding to the lever 2014.

[0036] To increase the stability of the connecting sleeve 2011 fixed to the chair leg 2, in this embodiment, anti-slip pads 20134 are fixedly connected to the side of the inner wall of the connecting groove 2012 and the side of the arc-shaped abutment plate 20131.

[0037] To facilitate the operation of the lever 2014 and thus the pressing of the abutment component 2013 by lever 2014, in this embodiment: the lever 2014 is rotatably mounted on the connecting seat 20142 via the connecting shaft 20141, and the connecting seat 20142 is fixedly connected to the side of the connecting sleeve 2011 and corresponds to the position of the force-bearing block 20133.

[0038] To facilitate adjustment of the backrest angle, in this embodiment: a backrest rod 3012 is fixedly connected to the bottom of the backrest 3. The backrest rod 3012 is rotatably mounted on the mounting base 301 via a rotating shaft 3011, and the mounting base 301 is fixedly connected to the side of the seat 1. A positioning bolt 302 for positioning the backrest rod 3012 is fixedly connected to the backrest rod 3012. An arc-shaped groove 3021 matching the positioning bolt 302 is provided on the mounting base 301 at the position corresponding to the positioning bolt 302.

[0039] To increase the stability of the chair leg 2 when it is placed, in this embodiment, a support foot 202 is fixedly connected to the bottom of the chair leg 2.

[0040] The working principle of this utility model is as follows: By setting the adjustment component 201, and by moving the lever 2014 to release the lever 2014 from the pressure of the force block 20133, the depth of the chair leg 2 inserted into the connecting sleeve 2011 can be adjusted, thus facilitating the adjustment of the height of the chair leg 2. After adjustment, moving the lever 2014 to press the force block 20133 allows the arc-shaped abutment plate 20131 to abut against the side of the chair leg 2, thereby achieving a stable positioning of the chair leg 2 after adjustment. Therefore, it can be used by users of different heights. At the same time, by loosening the positioning bolt 302, the backrest 3012 can be rotated, thereby adjusting the leaning angle of the backrest 3. After adjustment, tightening the positioning bolt 302 allows for convenient positioning of the backrest 3 after adjustment, thus increasing the comfort of use and leaning against the backrest 3, and improving the flexibility of the chair of this utility model.
