Building materials knowledge: construction and installation points of locks
The installation time of the lock is generally installed after the door is painted dry to prevent the paint from corroding the plating layer on the surface of the lock. Read the instructions carefully before installing the lock. Pay special attention to the fact that only the end with the fuse can be removed to install it (do not remove the end with the key). In addition, the installation of the door lock and the distance between the security door should not be less than 80MM, otherwise the security door will be on the door lock, and the security door will not be closed.
In the process of normally opening and closing the door, it is best to hold the handle and screw the lock tongue into the lock body. After closing the door, let go of the hand, do not force the door, otherwise it will reduce the service life of the lock. After the lock is used for a period of time, there will be a phenomenon that the opening is not smooth. Do not drop the oil into the lock cylinder, and grind the talcum powder or the pencil core into the fine core and inject it into the lock core. In addition, do not wipe the lock body and handle with a damp cloth, because some metal locks will wear off the coating and lose the aesthetic effect.
