Office Chair Fixed Plate
"Office Chair Fixed Plate" is not a standard industry term. Its specific function needs to be determined based on the usage scenario and may refer to components for base fixation, caster locking, or rotation control.
1. For Base Fixation or Enhanced Stability
It may correspond to a flat-bottomed round office chair base or a four-star swivel chair base. These components are typically made of metal (such as steel or aluminum alloy) and disperse pressure by increasing the base diameter or adding more support legs (e.g., four-star or five-star legs) to enhance chair stability. For example, a flat-bottomed round base (approximately 230 yuan) is suitable for scenarios requiring long-term fixed positioning, such as beside conference tables or office desks; a four-star base (approximately 125 yuan) reduces the risk of tipping over through multi-leg support and is commonly used in scenarios requiring frequent movement but short-term fixation.
2. For Caster Locking to Prevent Movement
It may correspond to an office chair caster lock or a universal wheel fixing pad. These components restrict wheel rotation through physical means. For example, a caster lock (starting at 1.12 yuan) is usually a plastic or metal clip that can be directly attached to the wheel axle after installation; a universal wheel fixing pad (29.93 yuan) achieves fixation by increasing friction (e.g., with a rubber pad) or using a mechanical locking structure. It is suitable for scenarios requiring temporary chair fixation, such as cleaning the floor or preventing children from accidentally moving the chair.
3. For Rotation Control
It may correspond to a die-cast aluminum alloy tray or an adjustable height and rotation base. These components integrate rotation control mechanisms. For example, a die-cast aluminum alloy tray (starting at 6.65 yuan) enables 360-degree rotation through internal bearings and can be paired with a lifting gas rod (such as the hydraulic rod commonly found in office chairs) for height adjustment; an adjustable height and rotation base (58.9 yuan) further incorporates a locking function, allowing users to control whether rotation is enabled through a knob or toggle switch. It is suitable for scenarios requiring flexible adjustment of sitting posture but occasional fixation of direction.
Additional Suggestions: For more precise component matching, it is recommended to clarify specific needs (such as "preventing chair movement," "fixing rotation direction," or "enhancing base load-bearing capacity") and further screen based on the chair model (e.g., whether it has a gas rod or the type of wheels). Some components may require professional installation, so it is advisable to consult the merchant for compatibility guidance before purchasing.
