Description

An office folding chair

Technical field

The utility model relates to the technical field of seats, in particular to an office folding seat.

Background technique

Office seats are widely used in office spaces. They are generally divided into folding seats and integrated seats. They are composed of a chair surface and a backrest. Workers can rest on the backrest. Some public seats can adjust the backrest angle to suit the needs. Workers have different resting angles. However, the existing office chairs have a single structure and can only meet daily office needs in function. During lunch breaks, workers can only choose to lie down on the desk or sit on the office chair with their heads raised to rest. .

The existing patent with publication number CN209862937U proposes a foldable office chair. The chair is combined into a foldable office chair by using an It is fixed with the X-shaped frame with fixed blocks. If you need to store it, you only need to lift the center panel, and the X-shaped frame and side panels will fold together under the action of their own gravity. When needed, First insert the claws at the upper end of the legs into the limit grooves on the seat plate, then insert the backrest into the upper ends of the legs and fix it with the fixing bolts. At the same time, the seat plate will also move between the claws and claws. It is fixed together with the supporting device under the action, and the X-shaped frame can be removed separately and used as a mazha when needed. Compared with the traditional folding office chair, this utility model is easy to disassemble and assemble, has diverse functions, and has a wider application range. .
