2020 - 11 - 26

The door lock is not very expensive, but if the anti-theft performance is lost in the process of using the door lock, the loss is immeasurable, so it is recommended that most users still need to maintain the door lock.

It is usually necessary to check the distance between the lock body and the buckle, as well as the height of the tongue and the hole of the buckle plate. We must also pay attention to the thermal expansion and contraction caused by weather changes to ensure that the gap between the door lock and the door and the door frame is reasonable, and to ensure the normal use of the door lock.

If you find it difficult to insert and remove the key in daily use, you can use a small amount of graphite powder or pencil powder in the lock chisel to ensure the smooth insertion and removal of the key. Lubricant should always be placed on the rotating part of the lock body to make it rotate smoothly. At the same time, it is recommended to check whether the tightening screws are loose once every six months.

The door lock cannot be exposed to rain for a long time, otherwise the small spring in the lock will rust and become hard. The falling rainwater contains nitric acid and nitrate, which will corrode the floodgate. Turn the key to unlock the door, and avoid pulling the key directly to open the door without returning the lock. Always keep its transmission stable and extend its service life, you can check it every six months or a year.
