The door switch is loud and wants to be replaced, I wonder if there is a silent door lock? 20

When people are buying household door locks, some people will be more concerned about what is a silent door lock, so as to determine whether to buy a silent door lock according to their understanding. When they decide to buy a silent door lock, people will be concerned about how to choose a silent door lock, so that they can use their purchase skills to buy a practical silent door lock. Since everyone is so concerned about the information of silent door locks, let's introduce to you what is a silent door lock and how to choose a silent door lock.

What is a silent door lock.

1. In fact, to put it simply, the silent door lock is a door lock with a sound loudness as low as 45 decibels, which is about 35% lower than the sound of general door lock products. It is understood that this series of door locks has been authorized by three national utility model patents. Many people in the industry evaluate the silent door lock, saying that the introduction of the indoor silent door lock can effectively reduce the noise problem caused by the door lock in daily life, especially suitable for bedrooms, libraries, hospitals and schools that need to be silent, as well as the elderly, children, pregnant women or the patient's family.

2. The oblique tongue adopts a spherical design, embedded with a high-strength nylon mute rubber ring, which greatly reduces the collision surface with the metal of the gusset plate, and cooperates with the high-strength silent diagonal tongue guide sleeve to effectively reduce the noise caused by the expansion and contraction movement of the lock tongue. The original patented gusset shrench design greatly buffers the door closing force of the oblique tongue, and the inner wall of the gusset box is made of high-strength silencing plastic to avoid the collision between the side of the oblique tongue and the metal of the gusset, and reduce the noise of opening and closing the door in a wide range.

How to choose a silent door lock.

1. Abrasion resistance. The material of the door lock determines the wear resistance of the lock. The judgment of the material can be solved by "looking", "checking", "listening" and other methods, such as the shape of the door lock, the appearance of the lock made of pure copper is generally treated by sandblasting and polishing, so its surface luster, compared with the copper-plated, its color is relatively dull, but natural.

When I got it in my hand and weighed it, I clearly felt that the pure copper door lock was obviously heavy, while the stainless steel door lock was 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 its sound, during the opening process of the door lock, the copper door lock is mostly solid, so its sound is not dull, and the stainless steel door lock sounds crisp.

2. Turn on the feel. The feel of the door lock opening process is very important, and the force required 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, it will not be used several times, and the door lock handle will sag due to the relaxation of the spring, affecting the service life of the door lock. Therefore, when purchasing, be sure to try the use effect of the door lock spring, and the feel should not be too soft or too hard.

3. Plating of door locks. The plating of the door lock determines the appearance of the door lock. When buying a door lock, first choose the material of the door lock, the door lock with good material, its plating is not easy to peel off.

Generally, the coating of a good door lock is not easy to corrode and peel. A good coating that is complete and shiny plays a great role in the aesthetics of the whole interior.

Opening and closing the door is unavoidable to have a sound, the sound is from the crack in the door or the sound of the door hitting the wall accidentally, there is no silent door lock, but you can press a small wooden stake on the wall, so that the door will not appear when the door hits the wall.

Yes, the silent door lock is to reduce the noise caused by the telescopic movement of the lock when the door is opened and closed, and it is generally used in bedrooms, hospitals, or libraries and other places where sound is required.

There are silent door locks, which are more suitable for people who prefer a quiet environment.

Hello! The loud sound of opening the door should be the aging of the bearing, you can put a little butter! Or replace the new door lock, many of them are the silent door locks you said now! For example, magnetic silent door locks, ball door locks, mortise door locks, glass door locks, and so on.

There are also chip-based products with higher cost performance. Now the widely used electronic password lock is based on the chip as the core, through programming.

In the field of security technology prevention, the electronic password lock with anti-theft alarm function replaces the traditional mechanical password lock, which overcomes the shortcomings of the small number of mechanical password locks and poor security performance, so that the password lock is greatly improved in terms of technology and performance.

Chinese name. Electronic locks.

Foreign name. electronic lock

Principle. The circuit is controlled by password entry.

Scope of use. Hotels, guesthouses, apartments, villas, homes.

Fast. Navigation.

Development process: domestic and foreign status quo, classification verification methods, operation process, related issues, purchase attention, function introduction.

Basic principle. Electronic locks, it is also based on 51 series single-chip microcomputer (AT89051) as the core, with the corresponding hardware circuit, to complete the password setting, storage, identification and display, drive electromagnetic actuator and detect its driving current value, receive the alarm signal sent by the sensor, send data and other functions.

The microcontroller receives the typed ** and compares it with the password stored in the EEPROM, and if the password is correct, it drives the electromagnetic actuator to unlock the lock; If the password is incorrect, the operator is allowed to re-enter the password up to three times; If it is incorrect three times, the single-chip microcomputer will alarm the intelligent monitor through the communication line. The single-chip microcomputer sends each unlocking operation and the driving current value of the electromagnetic actuator at this time to the intelligent monitor as status information, and at the same time sends the alarm information received from the sensor interface to the intelligent monitor as the basis for intelligent analysis.

1. Basic principles and hardware composition.

The system of a smart combination lock consists of a smart monitor and an electronic lock. The two are placed in different places, and the intelligent monitor supplies the power required by the electronic lock and receives the alarm information and status information sent by it. Here, the line multiplexing technology is adopted, so that the power supply and information transmission share a two-core cable, which improves the reliability and safety of the system.

The basic principle and composition of the intelligent monitor.

The composition block diagram of the intelligent monitor is composed of single-chip microcomputer, clock, keyboard, LCD display, memory, demodulator, line multiplexing and monitoring, AD conversion, buzzer and other units. It mainly completes the functions of communication with electronic locks, intelligent analysis and safety monitoring of communication lines.

There are silent door locks.

The sound is loud every time you open and close the door, you can tap it, if it is an abnormal noise, you can try to apply some oil.
