Lock knowledge

一、Use and maintenance of door locks

1. Never add oil to the lock cylinder. If the key is not flexible, you can put some pencil core scraps 

into the keyhole.


2. If the spherical door lock is inadvertently rotated 900 in a timely manner, it will become a 

permanent insurance. At this time, it can only be opened with a key. It is only necessary to rotate 

the insurance counterclockwise 900 to recover.


3. In normal use, if there is dirt, use a dry cloth (or add a little water) to remove it. Do not scrub 

with chemicals such as detergent. Otherwise, damage to the exposed protective film may cause 

discoloration.


4. When closing the door, it is best to hold the handle, screw the lock tongue into the lock body, 

and then let go of the door after closing the door. Do not force the door to hit the door, otherwise 

the service life of the lock will be reduced.


二、How to identify inferior door locks

1. First of all, look at whether the surface of the door lock is flat and smooth. The inferior door 

locks usually have a rough surface, pits and squats, and have obvious flaws, and the surface coating 

is extremely easy to leg color.


2. Then, carefully check whether the accessories in the door lock package are complete, and 

whether the hand feels comfortable. Usually, the inferior door locks are mostly from the small 

family workshops, and there will be problems in all aspects of the time.


3. See if the product has passed the test of the relevant quality inspection department of the 

country, and the technical indicators of the inferior quality door lock can not meet the national 

standard.


4. Finally, warn consumers that when buying a door lock, don't just look at the appearance and try 

to buy it when you buy it (open), but carefully check it and buy it after many trials. If you buy a lock 

with poor quality and materials, it will cause you a lot of trouble. If you shut it in the house, it will 

cause damage to life and property. Correctly choose the function and quality of the door lock. 

Bring convenience and security to you.
