Abstract

The invention discloses a set of connecting desk and chair, and relates to the technical field of educational tools. A desk, a chair and a connecting structure between the desk and the chair are included, the desk comprises a firs supporting cross rod, a first supporting vertical rod, a first supporting plate and a desk plate, the first supporting vertical rod is vertically installed in the middleof the upper end of the first supporting cross rod, the seat comprises a second supporting cross rod, a second supporting vertical rod, a second supporting plate and a seat plate, the second supporting vertical rod is vertically installed in the middle of the upper end of the second supporting cross rod, the connecting structure comprises a guiding sleeve, a guiding rod and a third hand-driving screw, the side edge of the second guiding sleeve is provided with an opening and is horizontally welded to the inner side of the first supporting cross rod, the guiding rod is horizontally installed on the outer side of the second supporting cross rod through a third hand-driving screw, and the guiding rod is slidably installed in the guiding sleeve. By arranging the part between the supporting vertical rod and the supporting plate to be adjustable, the adjustment of the heights of the desk and the chair can be achieved, the desk and the chair are slidably connected as a whole by arranging theguiding rod and the guiding sleeve between the desk and the chair, and armrests can be lifted and accommodated.

Description

technical field [0001] The invention relates to the technical field of educational supplies, in particular to a one-piece desk and chair. Background technique [0002] The desks and chairs sold on the market are generally wooden desks and wooden splits. The desk is made up of table top, table hole and table leg, and seat is made up of backrest, seat surface and chair leg. And the height of table leg and chair leg is generally fixed, once molding is produced, the height of desk and seat just can't be changed, therefore, the adaptability of this desk and seat is relatively poor, can't according to different grades. , students of different heights to adjust the height of tables and chairs. In addition, it is not easy to standardize the layout of indoor tables and chairs with such split tables and chairs. [0003] Chinese patent publication number is that CN203709530U discloses a kind of desk and chair height adjustment structure, relates to a kind of daily necessities. The ...
