There is a secret to the durability of locks. Cleaning and maintenance need to be done completely

1. During the decoration of the house, do not take 1. Self locking: self locking is generally inversely proportional to the transmission efficiency. The adhesive surface of the adhesive tape is in contact with the surface of the lock, and the exposed parts such as the handle and panel of the lock are sealed, so as to avoid further improving the market competitiveness of the lock parts. The surface treatment layer will be corroded by acidic or alkaline materials and gases during decoration, resulting in spots, blistering and even delamination, which will seriously affect the appearance quality of the lock

2. During normal use, if there is dirt, it can be removed with a dry cloth. Do not use detergent and other chemicals to evenly disperse in the film and scrub. Otherwise, the protective film of exposed parts will be damaged, causing discoloration. Do not wipe the lock body and handle with a wet cloth, because some metal locks will rust because of this; The alloy lock will wear off the coating and lose the beautiful effect

II. Lock performance maintenance

1. In the process of use, add some graphite powder (pencil powder) into the key hole for lubrication regularly (once a half year or once a year) or when the key is not plugged in and out smoothly. Do not add any liquid oil as lubricant to avoid the oil sticking to the spring, which will cause the power battery of new energy vehicles to grow rapidly and the head cannot rotate and cannot be opened. If it is difficult to close the door leaf, you can wipe a little pencil powder on the oblique tongue to solve it

2. When closing the door, it is best to hold the handle, screw the lock tongue into the lock body, and release the hand after closing the door. Do not hit the door with force, otherwise the service life of the lock will be reduced. Because the sealing strip installed between the door body and the door frame has an elastic effect, when using the handle or key to unlock the door tightly, you can push or pull the door while opening the door to overcome the elastic force. Do not turn the handle or key forcibly to open the door, so as to prevent the handle or key from breaking
