Abstract

The utility model relates to an elevating foot desk, particularly a desk used by matching a class chair of a student. The utility model is normally used for a long time and can effectively prevent and correct the myopia and the humpback of the student. The utility model is characterized in that at least nine desk foot elevating holes which have the same hole distance and the same hole diameter are respectively arranged on two desk feet, and desk leg fixed holes which are corresponding to hole number and have the same hole distance and the same hole diameter are also respectively arranged on two desk legs likewise. The hole distance and the hole diameter of the desk legs are consistent with the hole distance and the hole diameter of the table foot elevating holes. After every component of the utility model is assembled into the desk by using a screw fastener and welding technology, and before the utility model is used in a class at every term, according to different statures of every student, the serially assembled hole positions of the desk foot elevating holes and the desk leg fixed holes are readjusted and fastened to adapt to the sitting demand of the stature increasing year by year, so the myopia and the humpback of the student can be effectively prevented and corrected. The utility model has the advantage of simple structure, low manufacture cost, huge action and obvious social benefit.

Description

The lifting foot desk

One, affiliated technical field

The utility model is that a kind of student classroom that relates to is joined the desk that chair uses, and after lift tablet chair, the long-term supporting use of myopia-preventing frame, the myopia that can effectively prevent and correct the student is with bow-backed.

Two, background technology

To ending at present, owing to be subjected to the historical objective restriction of continuing to use, the whole nation most school desks seats height overhead is incompatible with most students' height, causes tens percent students' hypopsia, myopia and hunchback, and it has seriously influenced the national quality level of the whole Chinese nation.

Three, summary of the invention

Incompatible at the most of school desks in present whole nation seat height and most student's height overhead, the present situation that causes many myopia of student and bow-backed and prior art deficiency, the utility model provides the desk of a kind of desk pin energy lifting, and it can effectively prevent and correct student's myopia with bow-backed.

The technical scheme that its technical problem that solves the utility model adopts is:

The utility model lifting foot desk is assembled with corresponding screw fastener or welding procedure by table footmuff, table pin, table pin lift span, table pin crosspiece, table bucket, desktop, table quarrel, table leg, table leg fixing hole and table leg frame, it is characterized in that: be provided with 9 same pitch-rows respectively at least on two table pin, with a pin lift span in aperture; On two table legs, be respectively equipped with the same pitch-row of corresponding hole count too, with the table leg fixing hole in aperture; The pitch-row of table leg fixing hole is consistent with the pitch-row of table pin lift span; The aperture of table leg fixing hole is consistent with the aperture of table pin lift span; Table pin lift span and table leg fixing hole are adorned height as required and are carried out the fastening table that is assembled into screw fastener.Before each term, used in the classroom, should adjust lift span position with fastening table pin lift span and table leg fixing hole again by each different height that take a seat the student, adapting to the demand of taking that its stature constantly increases, thereby can effectively prevent and correct its myopia and bow-backed purpose.

The beneficial effects of the utility model are: simple in structure, cheap, ride comfort, effect are huge, and social benefit is obvious.
