The term 'Free Door' has different meanings in various contexts. According to currently available public information, it primarily falls into two categories: physical doors (for buildings/industrial use) and proxy software (network tools). The following are usage tips for both types of 'Free Door':
Physical Free Door (Anti-collision Door/Passage Door) Usage Tips
Applicable to supermarkets, workshops, cold storage, hospitals, and other places with double-sided opening and automatic rebound doors. Its core feature is that it does not require manual operation; it opens automatically upon collision and closes by its own weight or gravity mechanism.
Correct Passage Method
People or carts/forklifts should pass through at a uniform speed, avoiding sudden pushes to reduce impact damage to the door and hinges.
Children should use it under adult supervision to prevent accidental triggers or pinching injuries caused by running.
Maintenance and Precautions
Regularly check if the door axis is flexible and whether the track is free of debris to ensure smooth opening and closing.
If the door body is loose, makes abnormal noises, or is deformed, report for repair promptly to avoid safety hazards.
Daily cleaning only requires wiping the door body and keeping the sealing strips dust-free, particularly in cold storage or cleanroom environments to maintain sealing performance.
Applicable Scenario Optimization
In high-traffic passages (such as workshop logistics entrances or cold storage entries), free doors can significantly improve passage efficiency and reduce energy loss (such as cold air leakage).
The door materials (such as ABS engineering plastic, aluminum alloy) are corrosion-resistant and impact-resistant, suitable for humid, dusty, or low-temperature environments.
