Office Chair Fixed Slide Rod
The office chair fixed slide rod mainly achieves its function through pneumatic rod fixing accessories and caster fixers, with its core role being to restrict rotation or sliding and enhance usage stability.
Pneumatic Rod Fixing Accessories: Restricting Lifting or Rotation Functions
Some pneumatic rods achieve a fixing effect through special designs or additional accessories. For example, the "rotating-only, non-lifting pneumatic rod" locks the lifting function through its internal mechanical structure, retaining only the rotation function. It is suitable for scenarios requiring a fixed height, such as fixed-height office chairs or children's study chairs. Such products are usually produced by professional home accessory manufacturers. For instance, the accessories provided by Foshan Shengdeli Home Furnishings Co., Ltd. cost about 41 yuan and are suitable for scenarios with high requirements for height stability.
Another type of accessory is the rotation fixer, which restricts the rotation of the pneumatic rod through an external locking device. For example, the "metal pneumatic rod non-rotating locking accessory" provided by Hangzhou Jiande Kailei Trading Company achieves rotation fixing through mechanical buckles or thread locking, costing about 117.6 yuan. Such accessories are mostly used in scenarios requiring complete directional fixing, such as medical chairs and laboratory chairs, to prevent directional deviation due to accidental touches.
Caster Fixers: Preventing Chair Sliding
Caster fixers restrict the movement of universal wheels through physical barriers or friction, commonly in the form of anti-slip mats or buckle-type fixers. For example, the "universal wheel fixing mat" from Guangzhou Ousheng Plastic Products Co., Ltd. uses high-density rubber material to achieve anti-slip by increasing friction with the ground, costing only 1.87 yuan. It has monthly sales exceeding 20,000 units and is suitable for smooth floors such as wooden or tiled floors.
Another type is the buckle-type fixer, such as the product from Guangzhou Yichen Plastic Hardware Co., Ltd., which directly fixes the wheel axle through plastic buckles to prevent wheel rotation. This design is easy to install and costs the same as the anti-slip mat at 1.87 yuan, but has lower sales (834 units per month), possibly due to a narrower range of applicable scenarios (such as short-term fixing needs) or insufficient user awareness.
Selection Advice: Match Functions According to Needs
If you need to fix the chair's height or rotation direction, prioritize pneumatic rod fixing accessories; if you need to prevent chair sliding, caster fixers offer better cost-effectiveness. When purchasing, pay attention to product material (e.g., metal accessories are more durable), compatibility (the diameter of the pneumatic rod needs to match), and installation method (some require professional tools).
