Description
Technical field
The present invention relates to the apparatus field of life, teaching, more specifically more particularly to a kind of class for facilitating telescopic adjustment
Tables and chairs.
Background technology
The most of the time of student is spent before desk and chair.Student's learning time of bending over the desk daily is long, while is in again
The critical period of body development.If abnormal sitting posture is true, the lighter can cause that neck is uncomfortable, loses one's head, blurred vision, four limbs
The symptoms such as powerless, tired sleepiness, severe one cause the diseases such as myopia, bow-backed, cerebral angiospasm and deformity of spinal column.Properly, it is good for
The desk and chair of health is the important external environment of training student good sitting position.
Existing tables and chairs are the desk and chair of level altitude mostly, it is impossible to the use demand of different height students is adapted to, such as
The higher classmate of height using when it is possible that bend over hunchback the phenomenon that, eye distance desktop when the shorter classmate of height uses
Myopia may closely be induced by crossing.
There are also the tables and chairs of manually adjustable height on the market, increase the cunning arranged vertically in desk (or chair) both sides
Slot and sliding rail, and set one group of pin hole from top to bottom reach in the pin hole by inserting pins into different location and adjust desk (or chair
Son) height purpose.But this kind of tables and chairs adjust it is cumbersome, and while adjusting be typically with personal experience or naked-eye observation into
Row is adjusted, and can not accurately adjust the height for being most suitable for oneself height.It can be seen that these modes it is very time-consuming, it is laborious and
Efficiency is low..So how to provide it is a kind of can conveniently adjust height, desk and chair simple in structure, be those skilled in the art need
Technical problems to be solved.
