Integrated desk-chair structure

Abstract

The invention discloses an integrated desk-chair structure, which can realize stable resetting of a seat plate and folding of a desk plate. A seat plate resetting mechanism comprises a supporting seatarranged on the front side of a support, a mounting seat arranged on the seat plate and hinged to the supporting seat, an air spring with the two ends hinged to the supporting seat and the mounting seat, and a first torsional spring horizontally arranged on the supporting seat and having two ends fixedly arranged on the supporting seat and the mounting seat. A desk plate folding mechanism comprises a fixing base arranged on the rear side of the support, supporting rods arranged on the left side and the right side of the desk plate, a second torsional spring horizontally arranged on the fixingbase, a ratchet wheel with a ratchet wheel tooth, a pawl located below the ratchet wheel and rotationally arranged on the fixing base, an acting wheel with a tooth part, and a fixed shaft horizontally and fixedly arranged on the supporting rods and the ratchet wheel. The front ends of the supporting rods, the ratchet wheel and the acting wheel are coaxially and rotationally arranged at the top end of the fixing seat; the upper and lower ends of the second torsional spring are connected with the front side of the pawl and the fixing seat; the acting wheel is provided with an arc-shaped hole into which the fixed shaft is inserted; the tooth top surface of the tooth part is higher than the ratchet teeth; when the desk plate is placed horizontally, the pawl is clamped in the ratchet wheel andthe tooth groove of the acting wheel.

Description

technical field [0001] The invention belongs to the technical field of teaching facilities, and in particular relates to an integrated desk and chair. Background technique [0002] Desks and chairs are indispensable teaching facilities in the teaching process. At present, most of the desks and chairs used in schools are independent (or called combined desks and chairs), and seat boards and table boards are mostly fixed mechanisms and cannot be adjusted. With the development of technology and the improvement of teaching needs, one-piece desks and chairs have been developed and used in classrooms, especially in university classrooms. In the classroom, in order to save space, the seat board and the table board are designed with a foldable storage structure, so as to free up more space for students to walk between the seats. [0003] Among them, the structural design of the seat board generally adopts a gravity return mechanism, torsion spring, etc. However, the process of ret...
