[0025] Example 1

[0026] See also Figures 1 to 5 , which is the first embodiment of the present invention, and this embodiment provides a technical solution: a leisure chair based on ergonomics, comprising

[0027] A chair board body 1, and two bottom support frames 2 fixed to the bottom of the chair board body 1 by multiple bolts;

[0028] And an adjustable lumbar support 3 arranged on the surface of the chair board main body 1, including a base pad 31 slidably arranged on the front surface of the chair board main body 1, an arc-shaped support pad 32 installed on the front surface of the base pad 31, a T-shaped rear seat 33 fixed on the rear surface of the base pad 31, and a T-shaped slide groove 34 opened on the front surface of the chair board main body 1, the T-shaped rear seat 33 is slidably located in the T-shaped slide groove 34, the arc-shaped support pad 32 is a sponge pad, so that the position of the arc-shaped support pad 32 can be adjusted by sliding up and down to meet the usage requirements of different users, and the adjustable lumbar support 3 also includes a limiting component, which is used for stable limiting of the arc-shaped support pad 32 after the position is adjusted to ensure the stability of the arc-shaped support pad 32.

[0029] In this embodiment, preferably, the limiting component includes a rectangular rear groove 35 opened on the rear surface of the chair plate body 1, a limiting strip 37 is arranged in the rectangular rear groove 35, a limiting plug 38 is rotatably installed on one side of the limiting strip 37, a plurality of adjustment holes 310 corresponding to the limiting plug 38 are opened between the rectangular rear groove 35 and the T-shaped slide groove 34, a limiting plug 39 corresponding to the limiting plug 38 is opened on the surface of the T-shaped rear seat 33, and the front end of the limiting plug 38 passes through one of the adjustment holes 310 and is inserted into the limiting plug 39, which can be used in daily use. During the process, the T-shaped rear seat 33 and the arc-shaped support pad 32 are stably limited. Subsequently, the limiting strip 37 only needs to be pulled sideways to remove the limiting plug 38, and the base pad 31 can be slid up and down to adjust the position of the arc-shaped support pad 32. The limiting component also includes strip side grooves 36 opened on the inner walls on both sides of the rectangular rear groove 35. The two ends of the limiting strip 37 are respectively screwed into the two strip side grooves 36, which can limit the limiting strip 37 to prevent the limiting strip 37 from lateral movement, thereby ensuring that the front end of the limiting plug 38 can be stably inserted into the limiting hole 39 during daily use.

[0030] In this embodiment, preferably, a shaft block 311 is fixed to the rear end of the limiting plug block 38, and the limiting strip 37 is rotatably sleeved on the shaft block 311, so that the limiting strip 37 can rotate smoothly.

[0031] The locking cam 314 is provided on the support frame 316 to lock the locking cam 316, so that the locking cam 316 can be locked in the locking cam 316.
