Description

A desk and chair for correcting sitting posture

【Technical field】

The utility model relates to the field of desks and chairs necessary for students to study, in particular to a desk and chair for correcting sitting posture.

【Background technique】

Desks and chairs are the main tools for students to place textbooks and bury their heads in writing. A good sitting posture can prevent students from myopia, correct their sitting posture, and avoid students leaning forward and dozing off in class. Generally, a sitting posture corrector is installed on the desks and chairs to make students sit. When it is not correct, it acts as a reminder to the students. The existing sitting posture correctors are generally directly fixed on the front side, both sides or the upper part of the table board through fasteners. The installation and disassembly of the sitting posture correctors are troublesome, especially after each get out of class, the sitting posture correctors are blocked in front of the students. , affecting the environment in the classroom and hindering students from playing. At present, desks and chairs for protecting eyesight and correcting sitting posture appear on the market, and their structures are also relatively complex, the production cost is high, and the production is difficult. According to the data, the formula for protecting eyesight and correcting sitting posture is: "one punch, one foot and one inch". A punch refers to the distance (5.5 cm) of the human body from the desk when reading and writing. One foot means that the eyes should be about one foot away from the textbook (33 cm). One inch refers to the distance between the finger holding the pen and the tip of the pen about one inch (3.33 cm).
