Abstract

The invention relates to the technical field of healthy household articles for children, in particular to a seat back lifting mechanism and a learning chair. The seat back lifting mechanism comprises a fixed pipe, a chair seat lifting sleeve, a chair back lifting sleeve, a first screw rod, a second screw rod, a first rotating handle for driving the first screw rod and a second rotating handle for driving the second screw rod. According to the seat back lifting mechanism, synchronous or asynchronous lifting adjustment can be conducted on the chair seat and the chair back, operation is labor-saving and convenient, low-age children can independently complete adjustment operation of the height of the chair back and the height of the chair seat, and the learning chair provided with the seat back lifting mechanism is more suitable for being used by the low-age children and has good economic benefits and social benefits.

Description

Technical field [0001] The present invention relates to the technical field of child health home supplies, and in particular, there is a seat back lifting mechanism and a learning chair. Background technique [0002] In the field of children's home learning products, existing children's learning chairs, the posture chair can only meet the function of the seat, while the adjustment is high, and it is necessary to improve the prerequisite for such a seat.
