Detachment of Office Chair Springs

The handling of detached office chair springs requires selecting the appropriate method based on the type. The repair steps for regular springs and those in lifting chairs differ, and it is essential to confirm the model of the accessories and check the status of the fixed components before proceeding.

Repair Steps for Detached Regular Office Chair Springs

If the spring is a serpentine spring similar to those in rainbow stools (usually an S-shaped steel wire spring with hooks at both ends), follow these steps:

1. Tool Preparation and Inspection: Use tools such as screwdrivers and wrenches to first confirm that the model of the detached spring matches the original accessory to avoid installation failure due to incompatible specifications.
2. Disassemble the Seat Covering: Carefully remove the outer fabric or leather covering of the seat to expose the internal spring structure, taking care to retain fixed components (such as screws and buckles).
3. Remove the Old Spring and Inspect the Base Frame: Take off the detached spring and check if the holes in the base frame have deformed due to prolonged use. If the holes are misaligned, gently tap them with a hammer to correct them, ensuring the new spring can fit accurately.
4. Install the New Spring: Align the hooks of the new spring with the holes in the base frame and press firmly to ensure they are securely fastened; if screws are required for fixation, tighten them alternately on both sides to prevent the spring from tilting due to unilateral force.
5. Test and Reassemble: After reinstalling the seat covering, press down multiple times to test if the elasticity is normal and ensure the spring is not loose or making abnormal noises.

Repair Steps for Detached Lifting Chair Springs

The detachment of springs in lifting chairs usually involves hydraulic structures or rivet-fixed components and requires handling based on the specific fault:

1. Spring Box Detachment: If the detachment is caused by the breakage of the small iron rivet inside, disassemble the seat shell and use electric welding to re-fix the broken rivet, then hang the spring hook back in place. If the spring hook is detached, simply reposition it and check if the fixing screws are tightened.
2. Hydraulic Structure Spring Detachment: Invert the seat, remove the base, and pull out the hydraulic rod (similar to a hydraulic bar with caps at both ends), checking if the spring has slipped off the hydraulic bar. If the spring is misaligned, reinsert it and confirm the buckle is locked; if the hydraulic bar is damaged, replace the entire hydraulic assembly.

Key Precautions

• Accessory Compatibility: Before operation, ensure that the model and size of the new spring match the original accessory exactly to avoid secondary detachment or damage to the furniture due to incompatible specifications.
• Component Status Inspection: If the spring is severely deformed (such as bent or broken) or the fixed components (such as rivets or screws) are damaged, it is recommended to replace them with new accessories directly rather than forcing a repair.
• Safe Operation: When welding rivets or disassembling hydraulic structures, wear protective gloves and goggles to prevent burns or splashing of metal fragments. If unfamiliar with the operation, it is advisable to contact professional maintenance personnel for handling.
