Inspection and maintenance of door frames: Regularly check the door frame for damaged or worn parts. If any problems are found, repair or replace the damaged parts in time to ensure that the structure of the door frame is stable.

Lubricate door hinges and locks: Door hinges and locks may need regular lubrication to ensure their smooth operation. Use appropriate lubricants, such as oil or grease, to maintain door hinges and locks. At the same time, make sure that the lubricant does not drip onto the floor or door surface, which can avoid the risk of contamination or slipping.
