The interior door lock industry enters the silent era

In indoor noise pollution, the noise caused by the door lock is one of the important sources, and the switch of the door lock often makes the noise peak in an instant. According to statistics, the sound of 0-20 decibels is like a falling leaf, so that people are barely aware of it; 20-40 decibels are very quiet, like dripping sound; 40-60 decibels are like a soft conversation in a library or bedroom; 60 -80 decibels is very noisy, as if it is in a busy traffic in the downtown area; 80-100 decibels are very noisy, nerve cells are destroyed; 100 decibels or more is unbearable, staying for one minute is temporary.

However, for the moment, the noise decibel value generated by most common indoor door locks is about 70 decibels, which is easy to adversely affect people's home life. This phenomenon began to receive the attention of the leading brand of door locks. Through the technological innovation, the famous door locks were the first to introduce indoor silent door locks with noise as low as 45 decibels, which greatly solved the door lock noise pollution in the home life. It is understood that the technology has been authorized by the country's three mute patents.

It is reported that the new "Indoor Silent Door Lock" of the famous door adopts a spherical design, embedded with a high-strength nylon silent apron, which greatly reduces the collision surface with the gusset metal, and cooperates with the high-strength silent oblique tongue guide sleeve to effectively reduce the lock. The noise generated by the telescopic movement of the tongue; at the same time, its original patented gusset shrapnel design greatly cushions the closing force of the oblique tongue. The inner wall of the buckle box is made of high-strength sound-absorbing plastic, which avoids the collision of the side of the oblique tongue with the metal of the gusset plate, greatly reducing the opening and closing of the door. Noise; In addition, the inside of the lock body is subjected to five-fold silence processing, which effectively reduces the noise generated by the movement of the components. It is worth mentioning that the product has passed 200,000 opening tests, long life and 10 years free warranty.

Silence can calm down and create a quiet office and home life. According to the staff of the Door Lock Association, the transformation and upgrading of the door lock field is imperative, and technological innovation is an important support point for the transformation. But what users care about is not the door lock technology innovation itself, but whether the innovation caters to or meets the needs of users. The emergence of indoor silent door locks is the value transition of the door locks from the attention function to the attention to the human home. This practice deserves industry thinking.
