The designers of Tata R&D investigated and studied, and finally developed a silent lock with magnetic attraction technology.
1. reduction: the exposed oblique tongue is cancelled, which reduces the friction of the internal structure of the lock and the metal collision between the original oblique tongue and the door frame stop, making it quieter.
2. Addition: magnetic attraction structure is added. When the door is closed, the magnetic attraction rod will automatically attract and play a locking role.
3. Soft treatment: Use soft materials to mute the contact point of the door lock in the door suction. When a collision occurs, the quiet door closing sound replaces the noisy metal collision sound.
