Folding Office Chair Disassembly

To disassemble a folding office chair, first identify its structural type, prepare tools such as screwdrivers, wrenches, and rubber hammers, and follow the structural order while paying attention to safety. The specific steps are as follows:

I. Preliminary Preparation and Structural Assessment
Before disassembly, observe the chair's structural type. Common fastening methods include screw fixation and rivet fixation. If rivets are used, prepare a small drill bit; if screws are used, select the corresponding screwdriver or wrench based on the screw type. Also, prepare a rubber hammer (for separating interference-fit components), pliers (for assisting in tightening screws), and other tools. Ensure the operating environment is spacious to prevent parts from falling and causing injury.

II. Core Disassembly Steps

1. Disassembling the Seat Back Panel
   Locate the screws at the connection point between the back panel and the chair frame. Use the corresponding screwdriver or wrench to loosen them counterclockwise. If the screws are difficult to turn due to rust or excessive tightness, use pliers to grip the screw head for assistance or spray a small amount of lubricant (such as WD-40) and wait 5 minutes before proceeding. After removing the screws, gently shake the back panel to separate it from the chair frame, avoiding excessive force that could deform the back panel.

2. Disassembling the Seat Panel
   Locate the screws (usually 4-6) that secure the seat to the chair frame at the middle or bottom of the frame. Unscrew them one by one in a counterclockwise direction. If there are snap-fit structures between the seat and the chair frame, use a plastic pry bar to gently pry them open along the seam to avoid scratching the seat surface. After removing the seat, check underneath for any hidden screws or connectors to ensure complete separation.

3. Disassembling Chair Frame Components

   • Leg Disassembly: Locate the screws at the connection point between the chair legs and the chair frame (usually located at the center of the five-star base or at the root of the legs). Use a wrench to unscrew them. If the screws are hidden under anti-slip pads, remove the pads first before operating. For integrated chair legs, you may need to gently tap the connection point between the chair frame and the legs with a rubber hammer to loosen them for separation.
   • Backrest Frame Disassembly: If the backrest frame is fixed to the chair frame with screws, simply unscrew them. If it is welded or riveted, use a small drill bit to drill off the rivet head (keep the drill bit perpendicular to avoid damaging the chair frame) or use an angle grinder to cut the rivets (requires professional operation).

III. Handling Special Components
If the chair is equipped with a gas lift, first secure the chair frame and gently tap the side of the connection point between the base and the seat cushion with a rubber hammer to gradually separate the interference-fit components through vibration. Do not pull or twist the gas lift directly, as this could cause the internal pressure to release and the lift to pop out, causing injury. After separation, store the gas lift separately to avoid heavy pressure.

IV. Post-Disassembly Organization
Sort the disassembled small parts such as screws, rivets, and snaps into sealed bags by location and label them (e.g., "backrest screws", "leg rivets") for easy subsequent repair or reassembly. If parts need to be replaced, record the model numbers of the damaged parts (such as screw diameter and length) for matching purposes.
