Angle-adjustable assembly table and chair

Abstract

The invention discloses an angle-adjustable assembly table and chair. The table and chair comprise a body isolation plate, converting installation frames, converting support racks, an angle-adjustable device, a movable plate body and a positioning device. The converting installation frames are arranged on two sides of the body isolation plate. A converting support rack is arranged in each converting installation frame. A converting support horizontal beam is arranged on each converting support rack. The angle-adjustable device is installed on the support horizontal beams. One end of the angle-adjustable device is hinged to the movable plate body. A drive device is arranged on the angle-adjustable device, and drives an auxiliary hinged seat to move upward and downward. The auxiliary hinged seat is installed in the movable plate body through an auxiliary slide rail. The fast switching between a table function and a chair function can be achieved through adjusting the position of a weight bearing plate to quickly adapt to the face-to-face discussion of students and cooperative communicative teaching. The inclined angle of the plate body is adjusted through the angle-adjustable device to better suit multiple studying conditions, and reduce the fatigue caused by long time head-down postures.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of teaching supplies, in particular to the technical field of an angle-adjustable combined desk and chair. [0003] 【Background technique】 [0004] At present, the desks and desktops used by students are basically horizontal. When writing, in order to achieve the purpose of accurate writing, the body will habitually lean forward and the head will be lowered. The flexed position not only increases the pressure in the cervical intervertebral disc, but also puts the neck muscles in a state of uncoordinated stress for a long time. The muscles and ligaments at the back of the neck are easily strained by stretching, and the writing posture of bending over for a long time is maintained. , It is easy to bend the spine, increase the burden on the legs and waist, cause physical fatigue, and affect the learning effect. Especially for students who are in the growth and development period, they may even cause my...

Problems solved by technology

[0004] At present, the desks and desktops used by students are basically horizontal. When writing, in order to achieve the purpose of accurate writing, the body will habitually lean forward and the head will be lowered. The flexed position not only increases the pressure in the cervical intervertebral disc, but also puts the neck muscles in a state of uncoordinated stress for a long time. The muscles and ligaments at the back of the neck are easily strained by stretching, and the writing posture of bending over for a long time is maintained. , it is easy to bend the spine, increase the burden on the legs and waist, cause physical fatigue, and affect the learning effect

Especially for students who are in the growth and development period, they may even cause myopia or hunchback. Modern teaching is no longer simply the traditional teacher-instilled teaching mode, but pays more attention to the cooperative and communicative teaching mode. Students discuss and communicate to achieve a more thorough understanding of problems. I understand, but the clumsy movement of desks and chairs is difficult to adapt to students' face-to-face discussion, cooperation and exchange teaching, so an angle-adjustable combination desk and chair is proposed
