In the noisy modern life, noise pollution is everywhere. Noise will not only cause hearing damage to people, but also cause physical and psychological damage such as insomnia to a certain extent. Generally, the noise reaches more than 50 decibels, which affects the normal rest of human beings. If it reaches 70 decibels, it will damage the nerves. The noise of ordinary door locks closing the door reaches about 70 decibels. This sudden noise not only affects people's normal rest and work, but may also cause physical and mental damage to people.
Through insight into people's lives, Mingmen discovered the impact of the sound of opening and closing doors on people. Starting from the heart, using damping and silent technology, Mingmen silent locks reduce noise by 50% compared with traditional door locks, and control the sound of door opening and closing at 30~45 Decibels, the sound range most suitable for life and rest.
Adopting the active mute technology of the lock tongue, adding a damper, the lock tongue actively slows down the speed when extending and retracting, so as to achieve double silence; create a fully silent square tongue and the square tongue is implanted with nylon material, so that the square tongue is also flexible when it stretches and slides Very good mute effect.
Made by Japanese original factory, when the door is closed to 15°, use the damping and pulling function of the door closer to slowly close, reduce the impact sound of the door and the door frame, and prevent children from pinching their hands
0~90°automatically close the door, 90~180°arbitrarily stop the door.
