Lock maintenance skills that must be understood these years

In the use of daily locks, there are always various problems. In order to maintain the appearance of the lock and extend the life of the lock, we should pay attention to its maintenance and maintenance. Then, if you really want to maintain good, the problem is coming:

1. What if the door fan is so tight?

If the door lock is installed, if it is difficult to close the door (squeezing tightly), it should be checked whether the gap between the door leaf and the door frame reaches a reasonable gap of 1.5mm-2.5mm, and the door cannot be forcibly closed, which will shorten the service life after long-term use. Sometimes due to the nature of the door leaf, there will be a phenomenon of cold and cold in the winter and summer. At this time, the door gap should be adjusted to avoid forced opening and closing, which will affect the normal service life of the door lock.

2, the door lock feels swollen what to do?

If the handle is tight after the door lock is installed or the key is locked and locked, check it:

A. Whether the minimum installation door thickness of the door lock is larger than the actual door thickness, the two sides of the handle bar or the lock core shaft are pressed tightly, and the rotation is not smooth or even stuck.

B. Check whether the position of the door lock opening is coaxial with the position of the actual perforated part of the door lock. If it is misaligned, the movable part and the door hole side will be scraped.

C. Check whether the lock tongue of the lock body corresponds to the lock tongue of the door frame buckle. If it is not centered, it will cause the lock tongue to scrape the door frame, and the hand feels bad and not smooth.

3, lock core maintenance:

During the use of the lock cylinder, when the key insertion and removal is not smooth, a small amount of graphite powder or pencil powder can be put into the lock cylinder slot to ensure smooth insertion and removal of the key. Never add any other oil to lubricate to prevent the grease from sticking to the marble spring, causing the lock to not rotate and not open.

4, surface maintenance:

In normal use, if there is dirt, use a soft cloth (or a damp cloth) to remove it. Do not scrub with chemicals such as corrosive detergent. Otherwise, it will shorten the life of the bright surface.

Always check the maintenance during the use of the lock. In this way, the service life of each lock can be maximized.
