Three words tell you the principle of magnetic lock.

If you ask Bian Xiao what career do you hate most in this world? Bian Xiao would reply that he was a thief. Thieves are really hateful. They will silently steal your precious or hard-won things when you are not paying attention. Over and over again. Dear friends, don't think that our technology is very developed now, and thieves have no chance to do it, but it is counterproductive. Ironically, the thief's skills have also been strengthened. Today, Bian Xiao introduces a newly invented lock-electromagnetic lock.

Magnetic lock (magnetic? Lock), also known as electromagnetic lock. It has a wide range of applications, including indoor and outdoor. There are three installation methods: surface-mounted type, embedded type and glass door type.

Magnetic lock application

Electromagnetic lock is mainly suitable for interlocking the front and rear doors of indoor high-voltage switchgear to prevent misoperation. It is an indispensable locking device for power generation and power supply departments. In addition, in order to meet the needs of integrated automation substation, some electromagnetic locks also add auxiliary contacts in the locks, which can provide users with a pair of corresponding switch contacts at the open and close positions of the locks, which is convenient for users to interlock the locks and fully automate sampling to avoid idling. It is an ideal locking device for modern substation equipment.

Magnetic lock is the product of our high technology at present, which ensures our personal safety and property safety within a certain range. Then let Bian Xiao introduce you to the working principle of magnetic lock.

Magnetic lock principle

Magnetic lock, as its name implies, can be seen from these three words how it works. In fact, there are only three words, that is, electricity becomes magnetism. So what is its specific principle? Let readers laugh, don't think that its specific principle is just these three words. Next, Bian Xiao will introduce its specific working principle in detail.

Its original design concept comes from electromagnet. Under certain conditions, two magnets will attract each other, which is actually to meet the principle that like magnets attract and opposite magnets repel. This is how the magnetic lock was invented and applied. It can be connected to the current itself. When the current passes through the silicon steel sheet (the internal part of the magnetic lock), the magnetic lock will produce a strong adsorption force, thus adsorbing the iron plate. This is a complete loc process. After locking, if you want to open it, it will be identified by the access control system (generally, the access control identification system will be installed in the place where the magnetic lock is installed), and the identification method is to look at its design requirements. So you can come in. If forced entry is required, the magnetic lock will have an automatic alarm system. This is not worth the loss!

Six brands of magnetic locks

1，Bida

Guangdong Bida Security System Co., Ltd. was established in 1992, specializing in the research and development, production, sales and service of electronic security products, and committed to providing professional access control solutions for users such as hotels, houses and office buildings. Products include all kinds of smart door locks, smart cabinet locks, smart boxes and smart access control equipment.

2. Adele (a variant of Adela) (F.)

Idyll is committed to making fingerprint anti-theft door locks for families for more than 20 years. In the past 20 years, it has become the choice of 2 million families and doors around the world. It is a special electronic lock for foreign embassies in China and Zhongnanhai, China.

3. Digil

Digil was established in China on 1990. After 20 years of development, it has become the largest manufacturer of electronic locks such as fingerprint locks, hotel locks and combination locks in China.

4. Ke Yuhua can

Keyu Intelligent Technology Co., Ltd. is one of the major manufacturers of intelligent door locks in China. Its production headquarters is located in Jiangmen, the first hometown of overseas Chinese in China in the Pearl River Delta, Guangdong Province, where the first smart door lock in China was born.

5. CISA Qiansha

CISA Group produces and sells lock cores, locks suitable for various door types, emergency escape devices, safes, door closers, padlocks, electronic locks and access control systems. CISA is the first company in the world to produce electronic locks with patents. Combining smart card with phase lock, taking smart card as electronic key, it became the first company in the world to develop smart card hotel lock system.

6. Young

Its predecessor was Zhongshan Sunshine Lock Factory, which was established in July 2000. Is a high-tech enterprise focusing on mechatronics intelligent locks.

The above is the principle of magnetic lock that Bian Xiao brought to you today. Next, let's talk about science. There may be some problems in the use of magnetic locks. 1. Can't the door be locked? There may be two reasons for this problem: loose power supply or power cord. The solution is actually very simple, just check the power input problem. 2. Insufficient tensile strength? There may be three reasons for this problem, that is, the power output problem and the deviation of door installation, and the magnetic lock needs to be cleaned.
