An automatic locking hook device for doors and windows

technical field

The invention relates to a lock hook structure, in particular to an automatic lock hook device for doors and windows.

Background technique

Locks are not only human necessities, but also cultural (folk) objects, which represent the culture of a country and nation in different historical periods. Locks in our country have lasted for thousands of years, and it was born almost at the same time as human private ownership. At first, human beings simply wrapped their personal valuables in animal skins, tied them firmly with ropes on the outside, and finally tied a special knot at the opening. This tightly bound knot can only be opened with a tool called "wrong". Wrong, also called "Xiao", "starter". It is made of animal teeth or bones, and is shaped like a sickle-shaped hook. In fact, the knot is the earliest lock, and the fault is the earliest key. This is the prototype of my country's lock. This kind was used from the Shang Dynasty to the Han Dynasty, and then it was changed to jade, which evolved into accessories on the clothing of nobles.

In the Yangshao culture period 5,000 years ago, our ancestors created wooden locks mounted on wooden frame buildings. This is the oldest lock in the world and can be called "the world's first lock". This kind of wooden lock has been inherited by the people. For example, the white wooden lock in the Ming Dynasty was used in the buildings in Zhejiang. There are similar wooden locks in the villages of the Yi people in Kunming today. Although the Yin and Shang Dynasties had entered the Bronze Age, copper was mainly used to make large drinking vessels, food vessels and sacrificial vessels, but it was not yet used to make locks. Its development period is from the Spring and Autumn Period and the Warring States Period through the Qin, Han, Wei, Jin and Southern and Northern Dynasties to the Sui, Tang, Song and Yuan Dynasties. Following the Bronze Age of the Yin and Shang Dynasties, the Spring and Autumn Period entered the Iron Age. Archaeological evidence shows that during this period, people used a large number of iron locks, bronze locks, silver locks, gilt locks, etc. The representative ones are bronze locks in the Western Zhou Dynasty. Locks, metal locks in the Eastern Han Dynasty, silver locks with shrimp tails in the Tang Dynasty and square body locks in the Song Dynasty all have a very high level of technology.

In particular, the iron three-spring locks of the Han Dynasty have been used in my country for more than 1,000 years. Its prosperous period was the Ming and Qing Dynasties, and locks of various materials developed simultaneously, mostly copper locks and iron locks, with more sophisticated craftsmanship and great innovation in unlocking difficulty and shape manufacturing. For example, the three-color bronze locks of the Ming Dynasty, the white crane locks of the Qing Dynasty, the combination locks, the secret door locks, the four-opening locks, the upside-down locks and the locks of various characters, animals and characters are dazzling and beautiful. Some locks have complex structures, ingenious designs and peculiar mechanisms, which are difficult for ordinary people to open.

Locks with complex structures are not suitable for doors and windows, but too simple locks cannot play the role of locking doors and windows. For this reason, those skilled in the art propose an automatic locking hook device for doors and windows to solve the problems raised in the above background.
