[0023] In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, the terms "installed", "connected", "connected" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood through specific situations.

[0024] Please refer to Figures 1 to 5, in the embodiment of the present utility model, a leisure chair with a conveniently adjustable lumbar support includes a base 1. A first bearing 16 is fixedly embedded in the upper surface of the base 1. The inner ring of the first bearing 16 is fixedly connected to a support beam 2. The upper surface of the support beam 2 is fixedly connected to a first support plate 3. The upper surface of the first support plate 3 is fixedly connected to a second support plate 13. The front surface of the second support plate 13 is fixedly connected to a backrest cushion 14. A strip-shaped opening 6 is formed in the front surface of the backrest cushion 14. Symmetrically arranged sliding grooves 7 are formed in the inner wall of the strip-shaped opening 6. A sliding block 8 is slidably connected to the inside of each of the two sliding grooves 7. The side surfaces of the two sliding blocks 8 close to each other are fixedly connected together by a connecting block 17. The front surface of the connecting block 17 is fixedly connected to a lumbar support plate 9.

[0025] A connecting plate 4 is fixedly connected to the upper surface of the first support plate 3. A seat cushion 5 is fixedly connected to the upper surface of the connecting plate 4, which can make people more comfortable when using the device. A lumbar support cushion 10 is fixedly connected to the front surface of the lumbar support plate 9. An anti-slip pad 11 is fixedly connected to the bottom surface of the base 1. Anti-slip bumps 12 arranged in a ring are fixedly connected to the bottom surface of the anti-slip pad 11. A fixing plate 18 is fixedly connected to the back surface of the second support plate 13, greatly increasing the stability of the base 1 and preventing the base 1 from moving.

[0026] A second bearing 19 is fixedly embedded in the upper surface of the fixing plate 18. The inner ring of the second bearing 19 is fixedly connected to an adjusting rod 20. Adjusting handles 23 arranged in a ring are fixedly connected to the outer surface of the adjusting rod 20. A limiting ring 24 is threadedly connected to the outer surface of the adjusting rod 20, which can facilitate people to limit the adjusting rod 20. A limiting block 21 is fixedly connected to the back surface of the second support plate 13. A threaded hole 22 is formed in the upper surface of the limiting block 21. The outer surface of the adjusting rod 20 is threadedly connected to the limiting block 21. A headrest 15 is fixedly connected to the front surface of the backrest cushion 14. It can not only facilitate people to adjust the height of the lumbar support plate 9 so that people of different heights can use it, but also make people more comfortable when using the device.

[0027] The working principle of the present utility model is as follows: First, people can place the device at the usage position. Subsequently, they can adjust the height of the lumbar support plate 9 according to their own height. Then, they can rotate the adjusting rod 20 by using the adjusting handle 23. The rotation of the adjusting rod 20 in cooperation with the threaded hole 22 can drive the fixing plate 18 to move. The fixing plate 18 can drive the connecting block 17 and the lumbar support plate 9 to move. After the height of the lumbar support plate 9 is adjusted, people can sit above the seat cushion 5 and lean on the backrest cushion 14 and the headrest 15. The setting of the limiting ring 24 can prevent the lumbar support plate 9 from moving by itself. The settings of the anti-slip pad 11 and the anti-slip bumps 12 can prevent the base 1 from sliding.
