When the chair needs to be lifted, step on the air intake pedal 10 with the right foot, push the air in the airbag 12 into the fixed lifting rod 4. Through the reset of the intake spring 11 and the airbag 12, air is sucked into the airbag 12 again. One-way valves are provided on both the airbag 12 and the fixed lifting rod 4 to ensure that air only goes in and does not come out. The air inside the fixed lifting rod 4 increases to achieve the purpose of raising the height of the chair. When the chair needs to be lowered, step on the air outlet pedal 19 with the left foot, drive the opening and closing plate 20 to lower, and the gas inside the fixed lifting rod 4 is discharged from the first air port 22 and the second air port 24. The sealing sleeve 25 and the sealing block 23 ensure that no additional gas leakage occurs. The air inside the fixed lifting rod 4 decreases to achieve the purpose of lowering the height of the chair. The lifting mechanism 3 allows the user to adjust the height of the chair only by sitting on the chair, and can easily adjust the height of the seat without getting up.
[0028] Compared with the related art, the multifunctional swivel chair provided by the present utility model has the following beneficial effects:
[0029] By providing the lifting mechanism 3 that can adjust the height while sitting on the chair, the user can easily adjust the height of the seat without getting up, providing greater convenience and comfort. The user can quickly adjust the seat height while sitting to adapt to different work requirements, reducing the time wasted by getting up to adjust the seat height, thereby improving work efficiency.
