Description

An adjustable desk based on ergonomics

technical field

The utility model relates to the field of desks, in particular to an adjustable desk based on ergonomics.

Background technique

Desks are a kind of student utensils that students will inevitably use in school, but at present most desks are fixed standard desks, and their height is fixed and cannot be adjusted. It is inconvenient. If the desk is too short, students need to bend down and bow their heads when studying, resulting in poor development of the cervical spine and spine. If the desk is too high, students will have their eyes too close to the desktop, which may lead to myopia if they are used for a long time.

In order to solve the problem of inconvenient height adjustment of desks, a variety of adjustable desks based on ergonomic design have appeared on the market. The height of the desk can be adjusted by adjusting the legs of the desk to adapt to students of different heights. However, these The desks of the desks are generally fixed horizontally. When young students write or read, their bodies usually lean forward habitually. Writing and reading on a horizontal desk for a long time will easily cause abnormal curvature of the spine of young students, which may cause serious damage. affect the health of students.
