Abstract

A complete set of desk and chair which comprises a desk and a chair is characterized in that the desk and the chair are supported by a single supporting leg severally and the desk supporting leg and the chair supporting leg are connected with a connecting beam to be a complete unit. Wherein a horizontal beam is arranged at the bottom of the chair supporting leg or the desk supporting leg or two horizontal beams are arranged at the bottom of the chair supporting leg and the desk supporting leg severally. The horizontal beam which is a straight beam or a herringbone beam is provided with a universal wheel severally at both ends and the desk supporting leg and the chair supporting leg are supporting legs with lift structure. The utility model has the advantages of saving material, simple structure, easy manufacture and low costs. The heights of the desk and the chair can be conveniently adjust thereby the desk and chair fit for the studying need of the people with different height by holding the appropriate distance between the eyes and the desk top in particular to being beneficial for student vision protection and myopia prevention. Furthermore the desk and chair can be moved at will by the universal wheel and the directions of the desk and chair can be changed easily and the connecting beam is convenient for hand-held of the desk-chair.

Description

Complete connection desk, chair

Technical field: the utility model relates to a kind of teaching aid, particularly complete connection desk, chair.

Background technology: existing desk and seat complex structure, materials are many, cost is high, and height is many can not be adjusted, can't adapt to the different people's of height requirement, particularly be difficult to reach, and existing desk and chair is mobile very inconvenient for the eyes of the required maintenance of the pre-myopia prevention of student and the distance of desktop; In addition, existing desk, seat can not change direction neatly.

Summary of the invention:

The purpose of this utility model is to provide a kind of complete desk, seat, overcomes the above-mentioned disadvantage of existing desk, chair, and its height that can arbitrarily change desk, seat simple in structure is adjusted its direction neatly, again can mobile easily desk, chair.

Technical solution of the present utility model is a kind of complete connection desk, chair, it is made up of desk and seat, desk and seat are respectively by single outrigger support, the desk supporting leg is connected into an integral body with the seat supporting leg through connecting Beam, there is the horizontal Beam of a level seat supporting leg or desk supporting leg lower end, perhaps all respectively there is the horizontal Beam of a level seat supporting leg and desk supporting leg lower end, and a universal wheel is respectively adorned at the two ends of horizontal Beam.

Desk and seat are the Liftable type structure of supporting leg: screw rod and screw-casing cartridge type lifting structure; Or stem stem and sleeve are through horizontal latch positioning type elevating structure.

The horizontal Beam of level is straight Beam or herringbone bifurcated Beam.

Universal wheel also can be adorned in desk supporting leg or seat supporting leg lower end.
