Selection of silent door locks:
1. Wear resistance.
The material of the door lock determines the wear resistance of the lock. The material can be judged by "looking", "weighing", "listening", etc., such as looking at the appearance of the door lock. The appearance of locks made of pure copper is generally treated by sandblasting and polishing, so its surface is shiny. , compared with copper-plated ones, its color is darker, but natural.
When you hold it in your hand and weigh it, you can clearly feel that the pure copper door lock is obviously thick and heavy, while the stainless steel door lock is lighter. Copper is not easy to make hollow, but stainless steel can be made hollow because of its strong plasticity. In terms of listening to the sound, when the door lock is opened, the copper door lock is mostly solid, so the sound is not dull, while the stainless steel door lock sounds crisper.
2. Turn on the feel.
The feel of the door lock during the opening process is very important. The required force cannot be too large or too small, which is mainly determined by the spring. The quality of the spring determines the feel and service life of the door lock. If the spring is not good, after only a few uses, the door lock handle will sag due to the relaxation of the spring, which will affect the service life of the door lock.
So when purchasing, be sure to try out the effect of the door lock spring yourself. The feel should not be too soft or too hard.
3. Plating of door locks.
The coating of the door lock determines the appearance of the door lock. When purchasing a door lock, first choose the material of the door lock. The coating of a door lock with good material will not peel off easily. Generally, the coating of a good door lock is not easy to corrode and peel off. A good, complete and shiny coating plays a big role in the aesthetics of the entire interior.
