Detailed description of the invention
In order to illustrate the technical solution of the utility model and technical purpose, below in conjunction with drawings and the specific embodiments, the utility model is described further.
As shown in Figures 1 to 4, a kind of multifunctional desk and chair, comprises following composition component chair back backup plate 1, seat 4, support 2, " Contraband " shape connector 5.
Described support 2 comprises the two-way bending pipeline section of left and right symmetry, and wherein arbitrary bend broken pipe section is equipped with:
1) sweptback first straight length in top, uses as installation chair back backup plate 1;
2) the first horizontal segment of extending forward of described straight length bottom, described first horizontal segment is placed on the ground;
3) front end of described first horizontal segment bends the second straight length extended obliquely upward;
4) upper end of described second straight length bends the second horizontal segment extended backward.
In said structure, described chair back backup plate 1 left and right sides is arranged between left and right two the first straight lengths respectively by rotating shaft, is all embedded with plate body between left and right two described first horizontal segments, the second straight length, the second horizontal segment.Plate body between two second straight lengths forms described seat 4, and the plate body between two first horizontal segments, the second straight length forms an incorporating section, can be used for placing the comparatively heavy articles such as school bag.
