Lock culture
China locks have been born for thousands of years. Wooden locks were found in Shao cultural sites, bronze locks appeared in the Western Zhou Dynasty, and metal locks were widely produced and used in the Eastern Han Dynasty. Until the mid-1950s, China ancient locks withdrew from the historical stage.
value
Chinese ancient locks not only have practical value, but also become precious historical evidence, which reflects the historical development track of woodworking and hardware technology from one side. From the aspects of its material, modeling design, mechanical structure, organ structure, carving, painting and calligraphy, the lock involves many disciplines, such as woodworking technology, smelting and casting, forging and cold working, art painting and calligraphy, copper and wood carving, power, physics, assembly, psychology, etc., all of which can be found in the lock, which reflects the historical, social, political, economic, cultural and living customs.
[Lock knowledge] Lock material
There are basically two types of locks, one is wooden lock and the other is metal lock. The production of wooden locks must go through the technological processes of sawing materials, chopping with axes, drilling holes, planing and drilling holes. Metal locks need to be smelted, gold, silver, copper, iron, embryo casting, cutting and cutting materials, welding and riveting, drilling holes, flattening and polishing. From raw materials to manufacture, a lock not only takes a lot of careful work by locksmiths!
After several generations of inventions and improvements by skilled craftsmen, the locks produced can be said to be hundreds of millions of trillion, and it is difficult to count the exact figures. From the locks handed down from generation to generation, there are many fine products, which are the crystallization of the wisdom of ancient craftsmen. It may be because the lock itself is a kind of confidential article, which is passed down from generation to generation by locksmiths and craftsmen, and the literati who write books and biographies rarely set foot in it, resulting in few records in historical classics, official history and unofficial history, and all the research on the lock art is almost blank so far.
In fact, the connotation of lock culture is still rich and colorful. There are many exquisite locks made by locksmiths in past dynasties, which are really wonderful locks made by Chinese craftsmen.
Locks are not only protective articles, but also have the functions of "management" and "decoration". There is also a kind of etiquette in international communication, in which a symbolic "key" is given as a sign of friendship.
