Door lock is the most frequent object in people’s daily life. Many people think that if they buy a lock at home, they don’t need to maintain it until it’s broken.The service life of the door lock can be greatly increased by carrying out maintenance in many aspects.
1. Lock body: As the central position of the door lock structure. To keep the handle lock open and close smoothly, it is necessary to ensure that the lubricant is in the transmission part of the lock body, so as to keep the rotation smooth and prolong the service life.It is recommended to check every half a year or once a year.At the same time, check the fastening screws to make sure they are tight.
2. Lock cylinder: When the key is not smoothly inserted and turned,pour a little bit of graphite or lead into the slot of the lock cylinder.Do not add any other oil for lubrication, as the grease will solidify over time.The lock cylinder does not rotate and cannot be opened
3. Check the fit clearance between the lock body and the lock plate: The best fit clearance between door and door frame is 1.5mm-2.5mm.If any change is found, adjust the position of the door hinge or lock plate.
The above is part of the knowledge about the maintenance of household locks.
