Office Chair Tray Machine

The following is key information about office chair trays:

I. Customization and Installation Some office chair tray products support customization to meet the needs of different chair types or functions. Taking the P600 computer chair as an example, the installation of its tray follows specific steps: First, align the tray with the screw holes on the seat cushion and use four short screws (specification 6×20) for preliminary fixation. Then, use a wrench to tighten the screws one by one to ensure stability. After fixation, insert the gas rod into the circular hole of the tray to complete the overall structural connection. During this process, pay attention to matching the screw specifications and aligning the holes to avoid shaking or damage due to improper installation.

II. Product Types and Prices Office chair trays (also known as bases) on the market exhibit diverse characteristics:

1. Brands and Materials: For example, Yonghao offers PU leather and flannel adjustable computer swivel chair trays with explosion-proof trays, adopting explosion-proof designs to enhance safety. Shenzhen Anjeni Trading Co., Ltd. provides multi-functional adjustable trays with metal frames, emphasizing structural strength and durability.
2. Price Ranges: The prices of trays vary significantly depending on the brand, material, and bulk purchasing requirements. For example, a single tray from Yonghao costs 91 yuan, suitable for small-scale purchases. In contrast, the metal tray from Shenzhen Anjeni Trading Co., Ltd. costs 18 yuan per unit but requires a minimum order quantity of ≥1000 units, making it suitable for large-scale production or dealer purchases.

III. Common Faults and Repairs After long-term use, trays may exhibit left-right shaking, a typical manifestation of mechanical fatigue mainly caused by long-term load pressure and frequent adjustments leading to component wear or loosening. The core repair approaches include:

1. Tightening Screws: Check if the screws at the connections between the tray, seat cushion, and gas rod are loose and use a wrench to tighten them one by one.
2. Replacing Worn Parts: If the internal gears, springs, or plastic parts of the tray show cracks or deformation, replace the corresponding parts.
3. Overall Replacement: If the main structure of the tray is severely deformed (e.g., a broken metal frame), replace the entire tray to restore stability. Before repairs, locate the fault points through visual inspections and manual shaking tests to avoid secondary damage caused by blind disassembly.
