Office Chair Anti-Explosion Base
The office chair anti-explosion base is a crucial component that ensures the safety of the chair, preventing accidental collapse and providing security for prolonged sitting. When purchasing a steel computer chair tray (including an anti-explosion base structure), the following key points should be noted:
1. Hole Spacing Compatibility The hole spacing must perfectly match the original chair; otherwise, installation failure or structural instability may occur. The mainstream specifications on the market include small-width trays (15.5x19.8cm), medium-width trays (19.5x19.8cm), and large-width trays (22x22.5cm). Measurements should be taken based on the center points of the screw holes to avoid safety hazards caused by dimensional deviations.
2. Anti-Explosion Plate Configuration Level The full-section anti-explosion plate version is more than 0.5kg heavier than the standard version. Its core function is to block the risk of gas rod over-extension through a thickened structure. If the user has a larger body weight or needs to recline frequently, it is advisable to prioritize this configuration to reduce the risk of explosion caused by gas rod failure.
3. Steel Plate Thickness Rationality The mainstream durable range is between 3mm and 3.5mm. Below this standard, deformation may occur due to long-term weight-bearing, while above this standard, the compatibility with the gas rod needs to be confirmed (an overly thick steel plate may affect the smooth extension and retraction of the gas rod). When purchasing, you can request the merchant to provide a material test report to ensure the thickness meets safety standards.
4. Control Direction Compatibility Markings such as fork left front and fork left rear on the tray represent the installation position of the adjustment handle and the direction of the internal connecting rods. Choosing the wrong direction will prevent the chair from adjusting its height or recline angle and may even damage the mechanical structure. Before placing an order, disassemble the old part to check the direction markings or consult the merchant for compatibility guidance.
5. Sinking Depth Adaptability The sinking depth directly affects sitting comfort: the greater the sinking amount, the lower the minimum seat height of the chair, suitable for short individuals or low-desk scenarios; the smaller the sinking amount, the higher the seat height, suitable for tall individuals or users who need to lift their legs while working. Before purchasing, measure the desk height and your leg length to ensure the adjustable range of the seat height matches your needs.
Additional Suggestions: Some anti-explosion base computer chairs support customization, with materials including metal, aluminum alloy, stainless steel, etc., styles including minimalist, modern, etc., and suitable occasions including enterprises, schools, etc. When purchasing, you can choose wear-resistant mesh fabric or high-load-bearing steel materials based on the usage scenario (such as whether frequent movement is required) and budget.
