The desk and chair capable of preventing the students from humpback comprises a seat plate; a first connecting frame mounted on the seat plate; a backrest mounted on the first connecting frame; a lifting assembly mounted on the first connecting frame; and clamping assemblies mounted on the two sides of the backrest. The height of the desk and chair can be adjusted through the lifting assembly, so that humpback caused by improper seat height is prevented; through the clamping assembly, the shoulders of a student can be fixed, and the body of the student is prevented from leaning forwards when sitting on the chair, so that hunchback of the student is prevented.

Description

technical field [0001] The invention relates to a desk and chair, in particular to a desk and chair which can prevent students from hunchbacking. Background technique [0002] Hunchback is a relatively common spinal deformation, which is a morphological change caused by thoracic kyphosis. It is more common in diseases such as spinal deformation in the elderly, improper sitting posture, rickets, ankylosing spondylitis, etc. A hunchback that can be corrected is called an active hunchback. Can not be corrected called fixed hunchback. Now many students have hunchback phenomenon. [0003] Students sit on desks and chairs most of the time, and there are no backrests on ordinary desks and chairs, so it is very easy to cause students to lean forward, which makes the sitting posture irregular, and students often need to study on the desk chair. It is easy to maintain an irregular sitting posture, and the back cannot be exercised and relaxed. The long-term irregular sitting postur...
