Anti-Slip Wheel Office Chair

Anti-slip wheel office chairs can achieve anti-slip or fixed effects through various methods. Common approaches include the following:

1. Wheels with Brake Lock Function
   These wheels typically have a diameter of 60 millimeters and are wrapped in soft PU material, which not only protects the floor but also reduces metallic friction sounds during movement. Their core design features a built-in locking mechanism. When users need to fix the chair, they simply press down the locking device, and the internal mechanical structure of the wheel immediately locks, keeping the chair firmly in place. To move the chair, they just lift the locking device to unlock it. This design is easy to operate and suitable for scenarios requiring frequent switching between fixed and mobile states, such as offices and meetings.

2. Gravity Wheels
   Gravity wheels also have a 60-millimeter diameter design. Their anti-slip principle is based on the internal mechanical structure's response to gravity. When the chair bears weight, the gear or spring mechanism inside the wheel increases the resistance to left and right rotation due to gravity, making movement more strenuous and thus reducing the risk of sliding. Additionally, the friction design of gravity wheels is relatively gentle, resulting in minimal noise during movement, making them suitable for environments with high noise-reduction requirements, such as libraries and laboratories.

3. Fixed Foot Pad Replacement Solution
   To completely fix the chair, the original wheels can be removed and replaced with dedicated fixed foot pads. These foot pads are usually made of rubber or plastic and feature anti-slip patterns on the bottom, achieving stability by increasing the contact area and friction with the ground. This solution is particularly suitable for use scenarios involving the elderly or children, preventing falls caused by accidental sliding. However, it should be noted that after replacement, the chair will lose its mobility, so usage needs should be planned in advance.

4. Bearing Hollow Wheels
   Some high-end anti-slip wheels feature a hollow design in the middle, incorporating high-precision bearings. The overall weight of the wheel is heavier, reducing sliding caused by an unstable center of gravity. The outer layer is also wrapped in soft PU material, and some models are equipped with locking buttons that can fix the wheel through mechanical catches when pressed. These wheels combine anti-slip properties with mobility flexibility, suitable for users with high requirements for chair quality.

5. Temporary Anti-Slip Method Using Invisible Tape
   For low-cost temporary anti-slip needs, invisible tape of appropriate width and moderate stickiness can be used. The tape is applied to the wheel surface in a crumpled manner, increasing friction by enhancing the roughness of the contact surface. This method is simple to operate and leaves almost no adhesive residue when removed, but the tape needs to be replaced regularly to maintain effectiveness, making it suitable for short-term use or emergency scenarios.
