Since the wooden locks could not withstand severe impact or fire, bronze was used to make the lock body in the Eastern Han Dynasty. At the time of the Tang Dynasty, ancient locksmiths used metal materials such as gold, silver, copper and iron to make locks with their extraordinary wisdom. Until the Ming Dynasty, the locks were developed into four categories, that is, horizontal locks, fancy locks, jewelry locks and torture locks. Ancient locks are delicate, mysterious and have rich cultural connotations. People often carved Chinese characters on the lock body, which were profound.
The Fish Lock
The reed lock in the Han Dynasty is also known as the horizontal lock. The lock body is designed as a reed structure, and the elastic force of the three plate-shaped copper pieces can be used to open and close the reed lock. As the reed device can make various changes and the key hole can be used to determine the key style, security and confidentiality have been greatly improved. At the end of the second century B.C., the reed lock made in China was introduced to the ancient Rome through the Silk Road. Up to now, the Museum of Graz in Austria still has its collection.
The Cam Lock
In the 8th century, the eastern Romans made the initial cam lock. The key cut was used to match with the blade so as to open or close the cam lock. At the time of 18th century, an British named Daniel Porter invented the rim lock. The metal plate inside the rim lock rotates by the force of the spring, and the rim lock will be opened only when the plate is rotated by the key firstly to touch the notch of the lock tongue. In the 19th century, European manufacturers invented the advanced rim lock, which increased the kinds of key cut to 1,600. And later various improvements made the key cut have tens of thousands kinds. Rim locks have beautiful appearance and are recognized as the symbol of locks and keys. They are made into various gold keys to symbolize peace, hope and friendship.
