Silent lock, also known as electric lock, is a mechanical lock device controlled by relay. At present, a series of products with different structures such as plug lock (anode lock), cathode lock (electric lock port), magnetic lock and electric lock have been formed.
1, in fact, simply speaking, a silent door lock is a door lock with a loudness as low as 45 decibels, which is about 35% lower than that of ordinary door lock products. It is understood that this series of door locks have been authorized by three national utility model patents. Many people in the industry have commented on the silent door lock, saying that the introduction of indoor silent door lock can effectively reduce the noise problem caused by door lock in daily life, and it is suitable for bedrooms, libraries, hospitals and other occasions that need silence, as well as the families of the elderly, children, pregnant women or patients.
2. The oblique tongue adopts a spherical design and is embedded with a high-strength nylon silent skirt, which greatly reduces the collision surface with the gusset metal. The high-strength silent inclined tongue guide sleeve effectively reduces the noise caused by the telescopic movement of the locking tongue. The original patented spring leaf design greatly buffers the closing force of the inclined tongue, and the inner wall of the buckle box is made of high-strength silencing plastic to avoid the collision between the side of the inclined tongue and the metal of the buckle plate and reduce the noise of the switch door in a large range.
Electromagnetic lock: As the name implies, the power-on lock produces magnetism, which locks the lock and attracts, while the power-off lock loses magnetism and the lock opens. Suitable for iron doors and wooden doors, easy to install. At present, the locks of general manufacturers are equipped with door position monitoring terminals, that is, you can know whether the locks are sucked or opened through the access control software. Suitable for outdoor places and offices. Installation is divided into concealed installation and exposed installation.
Electric lock: Most of the old electric locks are silent. Controlling the expansion and contraction of the lock tongue by energizing the small motor is troublesome to install and requires high installation technology. Suitable for iron gates. The advantage is obvious, you can use the key to unlock the lock, which is a feature that other access locks do not have.
The noise of door lock is easy to distract energy, interrupt thinking and disturb sleep, and then affect the quality of office and home life. The elderly, pregnant women and children are noise-sensitive people, and the impact of door lock noise on them is more obvious. The noise from most common door locks will also interfere with the quiet indoor environment.
Relevant data show that although the opening and closing time of ordinary door locks is short, the noise can often reach the peak of about 70 decibels in an instant. And the sudden noise reaches 60 decibels, and 70% people will wake up from their sleep.
