Home Security Tips: Lock Maintenance and Maintenance Methods

Lock maintenance and maintenance method 1: Always keep lubricant in the transmission part of the lock body to keep the transmission smooth and extend the service life. It is recommended to check once every six months or a year, and also check whether the tightening screws are loose to ensure tightness.

Lock maintenance and maintenance method 2: During the use of the lock, regularly (half a year or one year) or when the key is not inserted smoothly, a small amount of graphite powder or pencil powder can be smeared into the lock core slot to ensure the key is inserted and removed Smooth. But do not add any other oils for lubrication, to avoid grease sticking to the pin spring, resulting in the lock cannot rotate and cannot be opened.

Lock maintenance and maintenance method 3: Always check the clearance between the lock body and the lock plate, whether the height of the lock tongue and the lock plate hole is appropriate, the best clearance between the door and the door frame is 1.5mm-2.5mm. If any change is found, the position of the hinge or latch plate on the door should be adjusted. At the same time, pay attention to the thermal expansion and contraction caused by seasonal changes to ensure that the gap between the door and the door frame, the lock body and the lock plate is reasonable, to ensure the smooth use of the lock.
