Important factors affecting lock life

Hardware locks are the most frequently contacted items in our daily lives. However, many people believe that after buying a door lock or hardware at home, they can be replaced without maintenance until they are worn out. As one of the top ten brands of indoor door locks, Zongyi Hardware has guaranteed product quality, but if you do not pay attention to details and maintenance in daily life, door hardware such as handle locks can quickly be damaged.


The maintenance of hardware locks is divided into several parts, and maintenance in multiple aspects can greatly increase the service life of the locks. Let's introduce the experience of Zongyi Hardware, a 10-year door lock brand, to you:


1.Lock body: As the central position of the lock structure, the opening and closing of the handle lock should be smooth. It is necessary to always ensure that the lubricant is present at the transmission part of the lock body, so as to maintain smooth rotation and prolong its service life. The editor suggested that it is recommended to inspect the fastening screws once a year or half a year to ensure tightness.


2. Lock head (i.e. lock cylinder): During the use of the lock cylinder, one year or six months after the purchase of the door lock, or when the key is not inserted, pulled, and rotated smoothly, a small amount of graphite powder or pencil powder can be poured into the slot of the lock cylinder, which can ensure that the key is inserted, pulled, and rotated smoothly, and does not get stuck. However, it is strictly prohibited to add any other oil for lubrication, as over time, the grease will solidify and stick to the spring inside the lock cylinder, resulting in the lock cylinder being unable to rotate and cannot be opened.


3. Frequently check the fit gap between the lock body and the lock catch plate, and check whether the height fit of the lock tongue and the lock catch plate hole is appropriate. The best fit gap between the door and the door frame is 1.5mm-2.5mm. If any changes are found, adjust the position of the hinge or latch plate on the door. At the same time, pay attention to the cold contraction and heat expansion caused by the weather (wet in spring, dry in winter) to ensure that the gap between the door and the door frame, lock body, and lock buckle plate is properly matched to ensure smooth use of the lock.


The above is a part of the maintenance knowledge about household door locks summarized by Zongyi Hardware Editor. The company is committed to becoming one of the top ten brands of indoor door locks. In the face of numerous issues in the market, such as: What brand is good for door locks? Which brand of door lock is better? The editor of Zongyi Hardware tells everyone that, in fact, the choice of a door lock brand is only one of the conditions for quality assurance, and more importantly, how to maintain the door lock after purchase. Regular maintenance is an important factor in prolonging the service life of the door lock.
