Important factors affecting the life of locks

　　 laminated steel padlock is something that we frequently touch in our daily life. However, many people think that after buying a door lock or hardware at home, it can be maintained without maintenance until it is worn out. Replace the material with a new one. If you do not pay attention to details and maintenance in your daily life, door hardware such as handle locks will be damaged quickly.
 
　　 The maintenance of hardware locks is divided into several parts. The maintenance of multiple aspects can keep the service life of the door locks greatly increased. The following are some of the experiences:
 
　　1. Lock body: As an important position of the door lock structure, the opening and closing of the handle lock is smooth. It is necessary to always ensure that the lubricant is in the transmission part of the lock body in order to maintain smooth rotation and extend the service life. The editor suggests that it is recommended to check once half a year or once a year, and check whether the fastening screws are loose to ensure the fastening.
 
  2. Lock head (i.e. lock cylinder): When the lock cylinder is in use, one year or six months after the door lock is purchased, or when the key is not smoothly inserted and removed, you can pour a little bit into the slot of the lock cylinder Graphite powder or pencil powder, so that you can ensure that the key is inserted and removed smoothly, and it will not be stuck when you turn. However, do not add any other oils for lubrication, because over time, the grease will solidify and stick to the pin spring inside the lock cylinder, which will cause the lock cylinder to be unable to rotate and cannot be opened.
 
　　3. Always check the matching clearance between the tumbler padlock and the lock plate, whether the height of the lock tongue and the hole of the lock plate is suitable, and the clearance between the door and the door frame is 1.5mm-2.5mm. If you find any changes, you should adjust the position of the hinge or the lock plate on the door. At the same time, pay attention to the cold shrinkage and thermal expansion caused by the weather (wet spring, dry winter) 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.
