[0024] Example:

[0025] See also Figure 1-Figure 4 In the figure, an ergonomic chair that is easy to adjust in multiple parts includes an adjustable height support frame 1, universal wheels 2, a seat cushion 3, a back cushion 4, an armrest 5 and an adjustment component 6, a plurality of universal wheels 2 are evenly fixed on the outer side of the bottom of the support frame 1, the seat cushion 3 is arranged on the support frame 1, the back cushion 4 is detachably fixed on the outer side of the top of the support frame 1, two armrests 5 are symmetrically arranged on the outer side of the support frame 1 and the seat cushion 3, the adjustment component 6 includes an adjusting screw 7, two mounting frames 8 are symmetrically fixed to the outer side of the support frame 1 by bolts, a V-shaped block 9 is fixed on the mounting frame 8, a slide groove 10 is provided on the top of the V-shaped block 9, the adjusting screw 7 is rotatably arranged in the slide groove 10, a slide cylinder 11 is slidably provided in the slide groove 10, and the armrest 5 is arranged on the top of the slide cylinder 11.

[0026] Some implementation methods of the present application are described in detail below with reference to the accompanying drawings:

[0027] See also Figure 1-Figure 4 By setting an adjustment screw 7 on the outside of the support frame 1 to drive the slide 11 to move, the height of the armrest 5 can be adjusted, and the upper side of the armrest 5 can be flush with the desktop, which facilitates the transition of the arm from the armrest 5 to the desktop, avoids the arm being suspended in the air, and prevents the formation of mouse hand.

[0028] At the same time, the adjustment component 6 also includes an adjusting wheel 12 and a fixing frame 13. The bottom of the adjusting screw 7 passes through the V-block 9. The bottom of the V-block 9 is provided with a recessed groove for placing the adjusting wheel 12. The adjusting wheel 12 is fixed to the bottom of the adjusting screw 7. The fixing frame 13 is slidably arranged on the top of the V-block 9. The slide 11 is threadedly connected to the adjusting screw 7. The top of the slide 11 is fixed to the inside of the fixing frame 13. A mounting block 15 is fixed to the outside of the top of the fixing frame 13. A rotating groove 16 is provided on the outside of the mounting block 15. One end of the handrail 5 is rotatably connected to the inside of the rotating groove 16 to adjust the height of the handrail 5. At the same time, the outer end of the handrail 5 can be lifted by rotating the handrail 5 to facilitate people to enter and exit.

[0029] The adjusting screw 7 is driven to rotate by the adjusting wheel 12, and then the slide 11 is driven to move in the slide groove 10 through the threaded action of the adjusting screw 7 and the slide 11, so as to adjust the height of the armrest 5 and make the upper side of the armrest 5 flush with the desktop, so as to facilitate the transition of the arm from the armrest 5 to the desktop, avoid the arm being suspended in the air, and prevent the formation of mouse hand. By setting a rotatable armrest 5, when a person needs to get up and leave the chair, the armrest 5 is rotated upward, so as to lift the outer end of the armrest 5, so as to facilitate the entry and exit of the person.

[0030] It is worth noting that the fabrics on the seat cushion 3 and the back cushion 4 are made of high-density molded PU foam and flannel, which are flame retardant, anti-fouling and wear-resistant, have strong breathability and comfort, moderate hardness and softness, and good rebound performance. The support frame 1 and the back cushion 4 skeleton are integrally molded by ABS engineering plastic molds, and the structure is stable and durable.

[0031] See also Figure 3 In this embodiment, a support rod 17 is slidably provided at one end of the armrest 5 away from the mounting block 15, and a connecting block 18 is fixed to the end of the support rod 17 away from the armrest 5. A support plate 19 is fixed to the top of the connecting block 18, and the support plate 19 is slidably connected to the outer side of the armrest 5. There are two support rods 17 in each armrest 5 that are symmetrically distributed in parallel. The setting of the two support rods 17 can greatly improve the supporting effect of the support rods 17 on the support plate 19 and prevent the support plate 19 from twisting. By arranging a movable support plate 19 on the armrest 5, the supporting range of the armrest 5 is extended, and the arm can be made to transition to the desktop as smoothly as possible.

[0032] It is worth noting that both ends of the support plate 19 are provided with transition slopes 20 to improve the comfort of the arm when moving on the armrest 5 and the support plate 19. The outer side of the support plate 19 is coated with anti-slip material to improve the anti-slip effect of the support plate 19.
