These six strokes easily solve various problems of hardware locks
After opening the door, most of the friends will always push the door to the door frame and let it have the closest hug between the door. However, this is not what the door wants. After we open the door, we should rotate the handle and let After the door lock is retracted, and then the door frame is combined, the hand is released. In short, it is necessary to avoid a serious collision of the door lock, otherwise it will shorten its life.
When we open the door or close the door, we often turn it to it. Over time, it is not so flexible. Therefore, we need to ensure that the rotating part of the lock body has lubricant, so that the friction of the lock body itself can be reduced, thereby increasing The life of the lock itself, and in order to ensure the safety of the lock, we should always check whether the lock 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.
In addition to the above maintenance methods, we should always check the matching gap between the lock body and the lock plate, as well as the height and the fit of the lock tongue and the lock plate and the gap between the door and the door frame, etc., if these are improperly fitted We all need to make appropriate adjustments, otherwise it will easily have certain safety hazards and even shorten the service life of the locks.
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.
