DETAILED DESCRIPTION
[0020] The following is combined with Figure 1-4 This application is described in further detail.
[0021] The present application embodiment discloses an ergonomic lumbar correction chair. Figure 1-4An ergonomic lumbar correction chair comprises a seat plate 1, an outer wall of the seat plate 1 is provided with an elastic cushion 6, the elastic cushion 6 is convenient for improving the comfort of the human body, a connecting rod 11 is installed on the side outer wall of the seat plate 1 by bolts, the outer wall of the connecting rod 11 is fixedly connected with a seat frame 12, the outer wall of the seat frame 12 is fixed with a back cushion 10 in an integrated structure, the back cushion 10 and the back of the human body are used to improve the supporting force, the outer wall of the connecting rod 11 is bolted with an arc-shaped mounting block 13, and the outer wall of the arc-shaped mounting block 13 is provided with A slide groove 14, the outer wall of which is slidably connected to a sliding block 15, the outer wall of which is rotatably connected to a circular shaft 16, and the outer wall of which is fixedly connected to a lumbar cushion 9, the lumbar cushion 9 is designed as an arc-shaped convexity, which can fit the human spine, and the lumbar vertebrae of the human waist can be supported by the lumbar cushion 9, and at the same time, the sliding block 15 can be made to slide along the trajectory of the slide groove 14, so that the sliding block 15 drives the lumbar cushion 9 to move, so that it can better adapt to the lumbar vertebrae of more human bodies, thereby improving the practicality of the device.
[0022] A pneumatic rod 4 is provided on the bottom outer wall of the seat plate 1, and the pneumatic rod 4 is fixedly connected to the seat plate 1 by bolts. A connecting column 5 is fixedly connected to the bottom outer wall of the pneumatic rod 4, so that the height of the seat can be adjusted conveniently through the pneumatic rod 4.
[0023] The outer wall of the connecting column 5 is fixedly connected to a plurality of connecting frames 2 in a circular array, and the outer walls of the plurality of connecting frames 2 are all fixedly connected to universal wheels 3, so that the seat can be moved conveniently through the plurality of universal wheels 3.
[0024] The outer wall of the sliding block 15 on one side of the circular shaft 16 is fixedly connected with a spring 18, the outer wall of the lumbar cushion 9 is fixedly connected with a connecting block 17, and the connecting block 17 and the spring 18 are fixedly connected. Through the fixed connection between the connecting block 17 and the spring 18, the comfort of the lumbar cushion 9 for the human body can be improved through the connecting block 17 and the spring 18.
