How to maintain the door lock in life
The door lock is closely related to our life. The safety problem cannot be ignored. How to maintain the door lock correctly?
1. In the process of opening and closing the door on weekdays, it's better to hold the handle and screw the lock tongue into the lock body. After the door is closed, release the hand. Do not hit the door with force, or the service life will be reduced. Do not use wet cloth to wipe the lock body and handle, because some metal locks will rust; alloy locks will wear off the coating and lose the beautiful effect.
2. Always keep the transmission part of lock body lubricated to keep its transmission smooth and extend its service life. It is recommended to check once half a year or once a year, and at the same time check whether the fastening screws are loose to ensure fastening.
3. In the process of using the lock head, regularly (half a year or a year) or when the key is not smoothly inserted or removed, a small amount of graphite powder or pencil powder can be smeared into the lock cylinder groove to ensure that the key is smoothly inserted or removed. But do not add any other oil for lubrication, so as to avoid the grease sticking to the spring of the spring, resulting in the lock can not rotate and can not be opened.
4. Regularly check the fit clearance between the lock body and the lock plate, whether the high-low fit of the lock tongue and the lock plate hole is appropriate, and the best fit clearance between the door and the door frame is 1.5mm-2.5mm. If any change is found, adjust the position of the hinge or lock plate on the door.
