Wuchuan Office Chair Lifting

The lifting function of office chairs in Wuchuan is usually achieved through gas springs or mechanical devices, with adjustment methods mostly involving pulling up the control lever or turning the knob. However, special attention should be paid to safety issues, especially the quality and explosion-proof design of the gas springs.

Lifting Function Implementation Principles

The lifting function of office chairs is mainly achieved through two technologies:

1. Gas Spring (Gas Strut): This is currently the mainstream design, which achieves height adjustment by using high-pressure gas inside to push the piston. Users can simply pull up the control lever under the seat to lock or release the height. The advantages of gas springs include smooth adjustment and low noise, but their safety highly depends on their quality.
2. Mechanical Screw Device: Some low-end or special-purpose office chairs use a mechanical screw structure to adjust the height by rotating the knob under the seat. This design is simple in structure but has lower adjustment efficiency and is prone to wear over long-term use.

Core Safety Issues

According to the sampling inspection results of the State Administration for Market Regulation, the safety hazards of office chairs are mainly concentrated on gas springs:

• Explosion Risk: Inferior gas springs may rupture under high pressure due to insufficient purity of the internal gas, poor sealing, or thin tube walls, resulting in the ejection of metal fragments. The sampling inspection shows that the non-compliance rate of some batches is as high as 23.3%, with the main problems being that the gas springs have not passed the durability test or have not been equipped with explosion-proof steel plates.
• Lack of Explosion-Proof Steel Plate: Qualified products need to be equipped with an explosion-proof steel plate with a thickness of ≥2 mm at the bottom of the gas spring to block explosion fragments. If the product does not indicate this configuration or the base structure is loose, caution should be exercised when using it.

Usage Recommendations in Wuchuan

1. Prioritize Certified Products: When purchasing, ensure that the product has passed national standard certifications such as GB/T 10357.4-2013 "Furniture Mechanical Performance Test - Part 4: Stability of Chairs and Stools" to avoid buying "three-no" products.
2. Regularly Inspect the Gas Spring: Check the surface of the gas spring every six months for cracks, air leaks, or a loose base. If abnormal seat sinking or adjustment stuttering is found, stop using it immediately and replace the parts.
3. Avoid Rough Use: Do not frequently and quickly adjust the height or subject it to long-term overload (such as multiple people sitting on it at the same time) to reduce pressure fluctuations inside the gas spring.

If you need to repair or replace the lifting components, it is recommended to contact a professional furniture repair agency in Wuchuan to ensure the use of original or compatible safety accessories.
