Some friends, when opening the door, always push the door to the door frame very hard, so the multi-door lock is very bad. After opening the door, we should rotate the handle, lock the lock tongue, and then release the hand after the door frame is combined. In short, it is necessary to avoid serious collision of the door lock, otherwise it will shorten its life.
When you open the door and close the door, you must turn the lock body. It will become inflexible after a long time. Therefore, we must ensure that the rotating part of the lock body has a lubricant to reduce the wear of the lock body and increase the service life. In order to ensure the safety of the lock, we should always check whether the lock pin is loose.
In addition to the lock body we often turn, the lock cylinder is also a place we often touch. After a long time, the key will not be smooth during the insertion and removal process. Therefore, we need to add some lubrication to the lock cylinder. The item, of course, the lock cylinder is absolutely not able to add lubricant or some oily substances, therefore, we should choose to add some graphite powder, which is the pencil core powder, which can best lubricate the lock core.
Some friends often like to put some lubricating oil into the keyhole when the door locks are bun or tight. In this way, the door lock may be smooth soon, but because the oil is easy to stick, it will be locked in the eyes. It will easily accumulate dust and form oil putty, which will make the door lock more prone to failure. Therefore, do not add lubricant to the mesh lock eye unless necessary. You can cut some pencil pieces or some candle pieces, blow them into the lock core through a thin tube, and then insert the key repeatedly for several times.
In some cases, due to the gravity of the door leaf or the hinge of the door, the door leaf sinks and the door is locked or the door is not smooth. At this time, it is often difficult to open the door with a key and lock the door. At this time, do not forcibly twist the key, so as not to break the key and increase trouble. You should check the reason first. If the door leaf sinks due to loose leaf, the loose leaf should be fastened with screws. If the door frame is deformed or its cause is unrecoverable, start with the door frame and expand the lock tongue accordingly, so that the door lock switch door can resume normal and smooth.
