This office chair has a simple structure, is easy to operate, can be folded upright, has a small storage space, and is convenient for people to work while sitting or standing.
[0003] However, the overall structure of the aforementioned patent is inconvenient to store.
[0004] This proposal is put forward in order to improve and optimize the above-mentioned problems or shortcomings. Utility Model Content
[0005] A folding office chair adaptable to multiple scenarios includes a folding office chair seat and a folding office chair backrest hinged to the rear side of the folding office chair seat.
[0006] The bottom of the folding office chair seat is also symmetrically hinged with folding office chair support flip feet. The folding office chair support flip feet are hinged in the bottom hinge joint seats located at the four corners of the bottom of the folding office chair seat. When the folding office chair support flip feet are in the stored state, they are flat against the bottom surface of the folding office chair seat. The flip angle of the folding office chair support flip feet is 100 degrees. When the folding office chair support flip feet are flipped 100 degrees, they abut against the folding office chair seat to restrict the folding office chair support flip feet, thereby making it in a stable posture for easy sitting.
[0007] The actual usable length of the folding office chair's support legs is adjustable.
[0008] Preferably, the rear side of the seat of the folding office chair is symmetrically fixed with a seat hinge joint, and the lower side of the backrest of the folding office chair is symmetrically provided with a backrest pivot. The backrest pivot is hinged in the seat hinge joint. When the backrest of the folding office chair is flipped to the storage limit position, the backrest and the seat are parallel. The rotation stroke of the backrest is 120 degrees. After the backrest rotates 120 degrees from the storage limit position, the lower end of the backrest abuts against the rear side of the seat to restrict movement. This keeps the backrest at this angle for easy leaning.
[0009] Preferably, the seat of the folding office chair is also provided with through ventilation holes at intervals to facilitate ventilation when sitting.
[0010] Preferably, the folding office chair support foot includes an adjusting screw and a U-shaped leg rod, wherein the U-shaped leg rod is telescopically mounted on the adjusting screw.
[0011] Preferably, the two ends of the U-shaped leg are coaxially rotatably provided with adjusting screw hole sleeves, which are threadedly connected to the adjusting screw. When it is necessary to adjust the length of the folding office chair support foot, both adjusting screw hole sleeves need to be rotated at the same time, and the self-locking characteristics of the adjusting screw hole sleeves and the adjusting screw are used for fixing.
[0012] Preferably, the U-shaped leg is hollow and has internal grease for easy lubrication after the adjusting screw is inserted.
[0013] The advantages and positive effects of this utility model are:
[0014] When folded, it becomes a flat, plate-like structure, offering excellent storage capacity and easy portability.
[0015] The overall actual usable length of the folding office chair support legs can be adjusted by rotating the adjusting screw hole sleeve, making it more versatile. The U-shaped leg rod has a hollow design and is equipped with grease inside, which facilitates lubrication after the adjusting screw is inserted, making the process smoother.
