Description

Technical Field

[0001] This utility model relates to the field of office supplies technology, and in particular to a stable office chair. Background Technology

[0002] An office chair is specifically designed for prolonged sitting in an office environment. It not only needs to provide a comfortable seating experience but also help maintain correct posture, reducing discomfort and health problems caused by prolonged sitting. A good office chair can improve work efficiency while reducing pressure on the spine, neck, and lower back.

[0003] When using an office chair, users need to adjust the backrest angle depending on the environment. However, if the backrest angle is adjusted too far, the chair's center of gravity may shift backward when the user leans back. Since the bottom support area of ​​the office chair is fixed, this can cause the chair to tilt backward and the user to fall.

[0004] Based on this, a stable office chair was designed. Utility Model Content

[0005] This utility model addresses the shortcomings of existing technologies by providing the following technical solution: a stable office chair, comprising a seat plate, a cylinder adjustment seat fixed to the lower surface of the seat plate, a pneumatic lifting rod disposed below the cylinder adjustment seat, and the upper end of the pneumatic lifting rod fixed inside the cylinder adjustment seat, armrests fixed to both sides of the seat plate, a backrest disposed on the back of the seat plate, an adjustment component for angle adjustment disposed between the seat plate and the backrest, and a support component disposed at the lower end of the pneumatic lifting rod;

[0006] The adjusting component includes a hinge installed between the seat plate and the backrest, a wing plate is fixed to the side surface of the cylinder adjusting seat, and a first electric push rod is rotatably installed between the wing plate and the backrest.

[0007] The support component includes seven support rods arranged in an array along the lower side of the pneumatic lifting rod. Two casters are mounted on the lower surface of each support rod. A second electric push rod is fixed inside each support rod, and the telescopic end of the second electric push rod is fixed to the lower end of the pneumatic lifting rod. A guide rod is also fixed to the lower end of the pneumatic lifting rod, and the free end of the guide rod is movably installed in a hole opened on the surface of the support rod.

[0008] As an improvement to the above technical solution, the seat plate includes a seat plate outer shell fixed to the upper surface of the cylinder adjusting seat, a grid plate fixedly installed on the upper part of the seat plate outer shell, a cavity located below the grid plate inside the seat plate outer shell, a fan for upward air discharge installed in the cavity, an air inlet hole opened on the lower surface of the seat plate outer shell and communicating with the cavity, and a cushion adhered to the surface of the grid plate installed on the upper part of the seat plate outer shell.

[0009] As an improvement to the above technical solution, the cavity inside the seat panel shell is divided into two parts, left and right.

[0010] As an improvement to the above technical solution, fourteen guide rods are provided, and each pair of guide rods is movably installed in two holes opened on the surface of the support rod.

[0011] As an improvement to the above technical solution, a control button is installed on the upper surface of the handrail, a storage battery is installed on the lower surface of the wing plate, the first electric push rod, the second electric push rod and the fan are all electrically connected to the control button, and the control button is electrically connected to the storage battery.

[0012] The beneficial effects of this utility model are:

[0013] 1. An adjusting mechanism is provided between the seat panel and the backrest. This mechanism includes a hinge installed between the seat panel and the backrest, and a first electric push rod rotatably installed between the wing panel and the backrest. When the first electric push rod is energized, its telescopic end rotates the backrest around the hinge, thus adjusting the backrest angle. The lower end of the pneumatic lifting rod is equipped with a support component consisting of a support rod, casters, a second electric push rod, and a guide rod. The telescopic end of the second electric push rod, installed inside the support rod, is fixed to the pneumatic lifting rod. This allows the support area of ​​the support component to be adjusted by telescopically extending the support rod after it is energized. This solves the problem of the office chair's center of gravity shifting backward after the backrest angle is adjusted too much, improving the stability of the office chair after adjusting the backrest angle. The free end of the guide rod is movably installed in a hole on the surface of the support rod, allowing the support rod to be guided when it moves, increasing the stability of the support rod's movement when its position is adjusted by the second electric push rod.

[0014] 2. The seat panel consists of a seat panel shell, a grid plate, a cavity, a fan, and an air inlet. The grid plate fixed to the upper part of the seat panel shell is used to support the seat cushion. At the same time, the seat panel shell is provided with a cavity below the grid plate for installing the fan. This allows the air inside the cavity to pass through the seat cushion to dissipate heat on the user's buttocks when the fan is powered on, while the air outside the seat panel enters the cavity through the air inlet.
