Chassis knowledge of lifting office chair
Nowadays, many people usually pay attention to the appearance, function and price of office chairs when choosing office chairs, while knowledgeable people know that the core technology of office chairs lies in the design of chassis. A good chassis allows people to better operate and adjust the office chair. As long as we grasp this point, the selected office chair will be very comfortable and safe.
At present, the mainstream types of office chair chassis in the market are roughly divided into three types: one is the conventional three function chassis, which is relatively common and has a large market share. This chassis has two control devices: lifting control lever and knob, which can lock the back of the office chair, lift and adjust the weight of the back tilt elasticity. The operation is also very simple. The right control lever is the condition for controlling the back tilt of the chair. Pushing inward is to lock the back tilt state. Pulling outward is to release the back tilt locking state of the chair. You can adjust the back tilt angle of the chair by pressing back; Also, break the control lever clockwise to adjust the lifting height of the office chair.
The other is the work study four function chassis, which has two obvious characteristics compared with the conventional three function chassis. One is that the chassis uses wire control technology to avoid the control device extending directly from the internal structure like the conventional chassis, making the control position more centralized and beautiful. Second, the front and back adjustment and depth adjustment of the chair seat are added, so that the office chair can adapt to customers of different heights. This design makes users feel more intuitive and more comfortable. The depth adjustment of chair seat is one of the main differences between ordinary office chair and engineering office chair.
Finally, it is a five function chassis for engineering and learning. In addition to the above four functions, this chassis adds seat cushion angle adjustment to meet the needs of different users in more aspects. The design of this chassis is to closely combine the chassis and seat, so the manufacturer of office chair has assembled the chassis, seat and seat back together. After purchasing, the customer only needs to install the air rod and chair foot and chair wheel.
