Office Chair Leg Broken
The broken leg of an office chair can be repaired or replaced depending on the extent of the damage. Common methods include replacing the caster wheels, replacing the entire five-star base, or gluing the cracks.
If the broken part is the caster wheel, typically manifested as a wheel that doesn't rotate, is damaged, or has fallen off, the damaged wheel can be replaced accordingly. Before operation, confirm the type of wheel, common types include brake-equipped and regular types, etc. Different types may have different installation methods. When removing the old wheel, observe the connection structure between the wheel and the five-star base. Most wheels are fixed with clips or screws and can be removed using a screwdriver or by pulling directly. When installing the new wheel, ensure that the interface between the wheel and the five-star base is aligned, press firmly or rotate until the clip locks to prevent loosening and subsequent detachment.
If the broken part is the five-star base itself, such as fractures, severe deformation, or detachment from the central column, replacing the entire base is the most reliable solution. When removing the old five-star base, first flip the office chair and use a screwdriver or wrench to loosen the fixing screws between the central column and the five-star base. Some chairs may require the removal of the gas lift or base first. When selecting a new five-star base, pay attention to its compatibility with the original chair, including size, material (such as nylon, metal), and interface type, to avoid installation difficulties or unstable use due to incompatibility. When installing the new five-star base, align the central column with the interface of the five-star base and gradually tighten the fixing screws to ensure a secure connection.
If the damage is minor, such as small cracks in the five-star base, gluing can be attempted for repair. When preparing tools, choose a strong adhesive suitable for metal or plastic materials (such as AB glue, epoxy resin glue) and prepare clamps (such as C-clamps, rubber bands) to fix the cracked area. When gluing, first clean the broken surface to remove dust and oil, ensuring that the adhesive can make full contact; after applying the adhesive, quickly align the cracks and clamp them tightly, maintaining pressure until the adhesive is fully cured (usually taking several hours to a day). Note: The strength of glued repairs may be lower than that of the original structure and is only suitable for minor damage. Regularly check whether the cracks have expanded.
