The earliest locks were simple mechanisms set up by owners to prevent others from opening them. The simplest type of door lock was the latch, which was used in ancient China. There were stone locks without keys, which were bound with ropes or chains. During the Shang and Zhou dynasties, private ownership of production increased, widening the gap between the rich and the poor, and social conflicts became very prominent. At the same time, smelting technology matured and was immediately applied to the manufacture of locks.

The lock industry, as a result, saw the emergence of copper locks and iron locks that could only be opened with keys, matching different locks to different keys. With the rapid development of science and technology,Mechanical LockThe development of modern mechanical locks has a history of more than 100 years. The lock core is equipped with different lengths of tumblers, and the shape of the key must have corresponding tooth shapes to open it. Later, it developed into password locks, magnetic locks, electronic locks, laser locks, voice-controlled locks, and so on. Based on the traditional key, a set or more sets of passwords, different sounds, different magnetic fields, different sound waves, different light beams, and different images (such as fingerprints, retinal veins) are added to control the opening of the lock. Nowadays, the lock family has become very large, and it is constantly improving and updating. 吸卡直开详情页_01
