[0027] An adjustable leisure chair includes: a base plate 1, armrests 5 are provided on both sides of the base plate 1, a rotating block 7 is rotatably connected to the base plate 1, a seat back plate 8 is fixedly connected to the rotating block 7, a bracket 13 is provided on the seat back plate 8, the bracket 13 includes a fixed plate 131, a connecting rod 132 is rotatably connected to the fixing plate 131, the other end of the connecting rod 132 is fixedly connected to a clamping rod 133, a slide groove 11 is fixedly connected to the lower surface of the base plate 1, a fixed block 12 is slidably connected to the inside of the slide groove 11, the fixed block 12 includes a slider 121, a plurality of fixing grooves 122 are provided on the slider 121, and the clamping rod 133 matches the fixing groove 122.

[0028] First, rotate the rotating block 7 to adjust the angle between the seat back plate 8 and the base plate 1, and at the same time pull the fixed block 12 from the inside of the slide groove 11 to the outside, and clamp the clamping rod 133 in the fixing groove 122 at different positions on the fixing block 12, so as to adjust the angle between the seat back plate 8 and the horizontal plane, and the supporting strength is sufficient; if the clamping rod 133 is removed from the fixing groove 122, the seat back plate 8 can be laid flat, so that the leisure chair can lie flat, which increases the practicality of the device.

[0029] A first supporting leg 2 is disposed at the bottom of the base plate 1 , a second supporting leg 14 is disposed at the bottom of the slide slot 11 , and anti-slip pads 3 are disposed at the bottoms of the first supporting leg 2 and the second supporting leg 14 .

[0030] The first supporting leg 2 and the second supporting leg 14 provide sufficient supporting strength for the device, and the anti-skid pad 3 prevents the chair from moving on the ground due to body shaking when the user lies on the chair, thereby affecting the comfort.

[0031] The armrest 5 includes a fixing rod 51, a connecting plate 53 and an armrest plate 54. A fixing ring 52 is sleeved on the fixing rod 51.
