Description

The desk of adjustable height and the pre-myopia prevention of gradient

Technical field: the utility model relates to a kind of desk, relates in particular to a kind of adjustable height and gradient, the desk with pre-myopia prevention function.

Background technology: at present, in each, the employed desk in primary school is commonly fixed structure, because student's height differences is bigger, long-term write, in the reading process, tallish classmate must frequent bent body, bend over, be easy to generate fatigue, this is very unfavorable for the teenager who is in the period of growing; The shorter and smaller classmate of stature then because can not fully keep reasonably writing, reading distance, cause hypometropia easily.

Summary of the invention: in order to overcome the deficiencies in the prior art, the utility model aims to provide the desk of a kind of adjustable height and the pre-myopia prevention of gradient, it can regulate the height of desk voluntarily according to each student's height, reaches the prevention hypometropia, guarantees the purpose that juvenile healthy is grown.

The technical solution of the utility model comprises a body and the table frame that is made of table leg, table leg is a hollow-core construction, each fixes a worm gear that is provided with internal thread the top of each table leg, two worm screws be installed on the described table frame by support and with two preceding table legs, two after worm gear engagement on the table leg; Four are installed in the back side of a body with the leading screw of described screw-internal thread fit by hinge seat; Be arranged on the baffle plate of desktop inductor and loudspeaker are installed.

Be provided with pedal below described table frame, handle is fixed on the worm screw.

Compared with the prior art, the utility model is owing to adopted gear drive and lead screw transmission principle, the height and the angle of desktop can be regulated voluntarily according to each student's height, the desk that has overcome the conventional fixed structure can not adapt to the defective of part classmate stature, has satisfied the requirement that adolescent growth is grown.
