Abstract

The invention relates to a desk and chair, in particular to a desk and chair for correcting sitting postures of students. According to the desk and chair for correcting the sitting posture of the student, the height can be adjusted, the angle can be adjusted, and the sitting posture of the student can be corrected. The desk and chair for correcting the sitting posture of a student comprises a slotted base having two fixed guide rail frames connected to one upper side, a movable table plate structure arranged between the fixed guide rail frames, and a movable seat mechanism mounted on the otherside of the slotted base. The height of the cushion can be adjusted through a seat lifting mechanism, the angle of the cushion can be adjusted through a rotating shaft, the height of the desk board can be adjusted through a desktop lifting mechanism, and the angle of the desk board can be adjusted through a pin rod; therefore, the height of the cushion and the desk board can be adjusted accordingto the height of a student, the distance between the cushion and the desk board can be adjusted, and the sitting posture of the student can be corrected.

Description

technical field [0001] The invention relates to a desk and chair, in particular to a desk and chair for correcting students' sitting posture. Background technique [0002] At present, students use desks and chairs to attend classes, and the existing desks and chairs are generally matched, but the existing desks and chairs are simple in structure and single in function, and cannot be adjusted according to the height of students The height and angle of the desk cannot be adjusted for the height and angle of the chair, so it is easy to cause the student's sitting posture to be incorrect, thereby easily affecting the student's figure, and the student is easy to bend over. [0003] Therefore need to design a kind of desk and chair that not only can adjust the seated height, but also can adjust the seated angle, can also correct the student's sitting posture correction with the student's sitting posture. Contents of the invention [0004] (1) Technical problems to be solved ...
