One. What should I do if the indoor door requires excessive force to lock?
1. If the issue is due to deformation of the door frame, first remove the door frame. Then, remove any uneven areas and re-install the door frame.
2. If the door cannot close due to loose screws, first locate the loose screws and then tighten them back in place using the appropriate tools.
3. If the hinges of interior doors are damaged and prevent the doors from closing, simply remove and replace the old hinges with new ones.
Two. How to maintain indoor doors that cannot be closed after installation.
1、When opening and closing doors, try to gently push and pull, and avoid prolonged, forceful impacts, as this can loosen internal door components and reduce their lifespan.
2. Regularly wipe the facade with a soft cloth to maintain cleanliness, which can prevent corrosive substances from penetrating and also enhance the aesthetic appearance of the interior door.
3. Regularly apply a small amount of lubricating grease to moving parts such as hinges, lock latches, and locks to maintain lubrication and ensure smooth operation of doors and locks.
4. Do not insert foreign objects or inject machine oil into the lock mechanism of interior door locks. This can cause jamming and make the lock inflexible. If the lock is inflexible, a small amount of putty powder can be used for lubrication (use sparingly). If the inflexibility of the lock affects its operation, seek professional assistance.
5、The expansion bolts used during door frame installation should be regularly checked for tightness to the wall and door frame to prevent potential safety hazards.
