The invention relates to height-adjustable integrated table and chair. Currently, the specifications of most tables and chairs are fixed and nonadjustable, so that the existing table and chair are bad for the antisternum development of students, and the heights of the students are greatly different from one another, so that the heights of the tables and chairs can not be adjusted according to the practical situations of the tall and short students. The height-adjustable integrated table and chair comprises a table and a chair, wherein the table and the chair are integrated into the integrated table and chair by fixed cross rods, and a height-adjustable device is respectively arranged under each of the table and the chair; each height-adjustable device comprises a support vertical rod which is arranged under the table or the chair and can be adjusted up and down, each support vertical rod is fixed on a stand column, and the stand columns are arranged on the fixed cross rods; and a plurality of through holes which are opposite to one another are arranged on the support vertical rods and the stand columns, and movable connecting rods can be fixed by each pair of the through holes. The height-adjustable integrated table and chair have the advantages of being simple in structure, scientific to design, convenient to machine, convenient to operate and the like, so that the heights of the table and the chair can be adjusted according to the practical situations of the students.
Description
technical field [0001] The invention relates to a desk and chair, in particular to a height-adjustable integrated desk and chair. Background technique [0002] The high myopia rate of primary and middle school students has attracted much attention. A set of data shows: Taking vital capacity reflecting cardiopulmonary function as an example, compared with 2007-2008 in 2008-2009, boys decreased by more than 190 ml and girls decreased by more than 150 ml. In terms of vision, the myopia rates of boys and girls in 2008-2009 were 62.64% and 68.25% in primary schools; 79.70% and 87.32% in junior high schools; and 87.06% and 92.2% in high schools. In other words, by the junior high school stage, the vast majority of teenagers have become myopic.
