Description

technical field [0001] The invention relates to a seat with an adjustable seat surface, in particular to a lift chair whose seat surface is adjusted by rotating a handle. Background technique [0002] Currently known lift chairs have problems such as complex overall assembly relationship, complicated structure of parts and components, and high cost. Although some schemes are simple in structure, it is time-consuming and laborious to adjust, and it is not convenient to use. For example, patent 88204321.8 needs to adjust the position of the seat surface through pedals before use; patent 00257527.2 needs to make the upper and lower rotating plates The change of the rotation angle generated by the rotation is transmitted to the supporting screw, which makes it rotate a corresponding angle relative to the nut sleeve to complete the action. In addition, in the existing lift chairs, the lifting mechanism is placed under the chair surface, and the seat surface must be lifted and lo...
