How did the ancients prevent thieves and burglars? In ancient times, there were also "master keys" and "Combination lock" -- Zongyi
How did the ancients prevent thieves from entering and stealing? As early as the Western Han Dynasty, the most advanced metal reed locks in the world were widely used among Chinese people. At the same time, in order to enhance the anti-theft performance of the door itself, anti prying structures such as bolts, closures, and paving heads have been installed, and locks have been made into shapes such as fish and dogs, praying for the safety of the door.
What locks were used on ancient doors?
Dialect: "The household key, from Guan to East, is called the key between Chen and Chu
China is one of the first countries in the world to invent and use locks, but the locks used on modern family doors have basically become "foreign locks" -- in 1950, the locks invented by the ancient Chinese began to withdraw, and were first replaced by locks such as Pin tumbler lock.
What were the locks used on ancient doors to prevent thieves? From historical records, it can be seen that wooden locks were used in the early stages. In the Bronze Age of the Shang and Zhou Dynasties, the Chinese began to use "metal locks", but such bronze locks were not available to ordinary people. It was not until the emergence of iron locks in the Han Dynasty that locks became a necessity for folk families and their anti-theft function really came into play.
There are various types of metal locks, including gold locks, silver locks, copper locks, and iron locks, among which copper locks and iron locks are practical locks on family doors. In Yang Xiong's "Dialect" of the Western Han Dynasty, there is a saying: "The key to the household is from Guan to the east, and between Chen and Chu, it is called the key; from Guan to the west, it is called the key." It can be seen that at that time, folk doors began to be locked with locks.
In the Han Dynasty, metal locks opened a new chapter in the safety of Chinese family doors. What kind of lock is a Han lock? It is a type of lock with a reed structure, known as the traditional "reed lock". The simplest reed lock uses two reeds, usually three reeds, so it is also called a "three reed lock" within the circle. The principle of a reed lock is to use the elasticity of two or three plate-shaped copper plates to achieve the function of sealing and opening.
The reed lock is a true Chinese lock, and its safety technology has been leading the world for a considerable period of time. This type of metal lock structure actually appeared during the pre Qin period. At the end of the second century BC, reed locks were introduced to ancient Rome through the "Silk Road".
The emergence and use of reed locks mark the formation of the popular concept of "anti-theft locks". In order to ensure the anti-theft effect, the locksmith will increase the number of reeds as needed, with an additional 12 reeds, making the structure more complex; At the same time, by reinforcing and weighting the lock body, the anti-theft lock performance is more outstanding. Later on, more complex reed locks emerged, requiring several keys to open or additional hidden holes. The first user had no way to access the key, and this type of lock can be considered an advanced anti-theft lock from ancient times.
It is worth mentioning that in order to ensure the quality of locks, in ancient times, "Le Ming" was usually engraved on the lock, that is, the locksmith's name was engraved on the lock body, which was also one of the conventional and important means of ensuring the quality of handmade products in ancient times.
