Hongqiao Office Chair Disassembly

The disassembly of Hongqiao office chairs can be carried out in the order of chair wheels, gas rods, chassis, seat, and backrest. The specific steps and precautions are as follows:

I. Chair Wheel Disassembly

For most office chairs, the chair wheels are directly inserted into the slots on the chair legs. When disassembling, hold the chair legs firmly with one hand to prevent them from shaking and affecting the operation; grasp the chair wheels with the other hand and pull them out perpendicular to the direction of the slots. If the chair wheels are tightly connected to the slots, you can gently shake them left and right to loosen them before pulling them out. However, be sure to apply even force to avoid damaging the slots on the chair legs.

II. Separation of Gas Rod and Chassis

• Snap Ring Fixation: If the gas rod and the chassis are fixed by a snap ring, use snap ring pliers to remove the snap ring. Align the jaws of the snap ring pliers with the snap ring, gently clamp it, and expand it outward to make the snap ring detach from its fixed position. Then, you can pull out the gas rod.
• Nut Fixation: If it is fixed by a nut, use an appropriate wrench to unscrew the nut. Select a wrench of the right size, place it on the nut, and turn it clockwise or counterclockwise to unscrew the nut. Then, pull out the gas rod.
• Special Case Handling: For some height-adjustable office chairs, you need to invert the chair and use a rubber mallet to evenly tap the metal chassis at the connection between the base and the gas rod. At the same time, assist by掰动 (this word is a bit difficult to translate precisely in a general context; it could mean 'prying' or 'manipulating' depending on the exact action, here we use 'manipulating') the five-star feet to separate the gas rod. When tapping, be sure to apply moderate force to avoid damaging the components.

III. Disassembly of Seat and Backrest

For the vast majority of office chairs, the seat and the backrest are connected to the gas rod with screws. Use a screwdriver to unscrew the connecting screws to separate them. For height-adjustable office chairs, first remove the fixing screws of the plastic or metal chassis at the bottom of the seat cushion, and then loosen the seat cushion from the gas rod by tapping or shaking. When tapping, use a rubber mallet to gently tap the bottom of the seat cushion. Shaking means holding the seat cushion and shaking it left and right or back and forth to loosen its connection with the gas rod.

IV. Precautions

• Tool Preparation and Observation: Before disassembly, observe the overall structure and prepare tools such as a cross-head screwdriver, an adjustable wrench, and a rubber mallet. If the screws are rusty, you can drip some lubricating oil and let it sit for a while before operating. This will make the screws easier to unscrew.
• Gas Rod Handling: The gas rod is filled with high-pressure gas inside. It is not recommended to disassemble it yourself unless necessary. If you need to operate it, be extremely careful. It is best to do it with the assistance of an experienced person to prevent the gas rod from suddenly popping out and causing injury due to improper operation.
• Component Storage: It is recommended to store the small disassembled components in categories according to the steps. You can use small sealed bags to mark their corresponding positions to facilitate quickly finding the required components during subsequent assembly.
