The rapid development of science and technology has brought a lot of convenience to our lives. From the development history of the lock, it has also experienced a lot of changes in the dynasty.
As early as 5000 BC to 2000 BC, as productivity increased, humans began to have private property (small amounts) accumulated. In order to protect personal property, humans began to explore the locks. Originally, I used my skin to wrap my belongings. The knot is knotted firmly with the ropes. To open, you must use a "wrong" made of animal teeth or animal bones to pick up the knots layer by layer. This is the prototype of the most primitive locks and keys in China.
By the time of the Yangshao culture in 3000 BC, the Chinese ancestors created wooden locks mounted on wooden framed buildings. This is China's oldest lock in the world, and it can be called the "world's first lock."
In the future, with the development of society and the improvement of productivity, copper, iron locks, silver locks, jade locks and other different materials and locks of different shapes were created, and the craft skills were getting higher and higher.
The steel lock is still relatively unfamiliar to the general public. This article is a small series on the simple problems of steel locks, consulted professionals.
It is understood that the steel lock is a control and management function, which combines high-strength mechanical structure, high-stable electric control, and high-security digital identification. It is used for special places such as prisons and detention centers. Currently, there are special lock models: AD-1, AD-2 ;
Stainless steel lock features:
Special places such as prisons and detention centers are mostly iron doors. They are frequently used, barbaric, and have large error and deformation. The civilian locks usually equipped cannot meet this strength and environmental requirements. They are easily damaged during installation and use, and often fail and exist safely. Hidden dangers threaten the safety of the regulatory site.
Udis has fully considered this requirement for the AD-01 series of steel locks specially designed for this special environment. After years of practice and improvement, udis has the following functions:
1. Mechatronics design, stainless steel lock combines electronic technology and high-strength mechanical locks perfectly. It has strong anti-riot performance and deterrent power, and is firm and reliable.
2, the shell of the whole steel casting, anti-riot, anti-corrosion, not only can be applied indoors, but also suitable for harsh environments such as outdoor (such as in Xinjiang, Inner Mongolia and other extreme environments).
2, anti-mite, anti-destruction alarm.
3, the door, lock switch state is directly displayed in the lock panel, at a glance, so that the police are steady.
4, built-in lock body with control circuit, the company's original patent ID binding technology, greatly improving security.
5. This series of locks supports the network interface, and forms a special channel control network system with other equipments of the company to form an overall solution.
