Description

Automatic lock hook device for door and window

Technical Field

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

Background

The lockset is not only a human living article, but also a cultural (folk-custom) object, which represents the culture of different historical periods of a country and a nation. Locks in China have been extended for thousands of years, and are born almost at the same time as the proprietary system of human beings. Initially, humans simply wrapped the valuable property around the hide, tied firmly with a rope, and finally tied with special knots at the opening. The tightly tied knot can only be opened by a tool called 'wrong'. The wrong one is called "Xiao" or "Jie Ji". The lock is made of animal teeth or animal bones, is shaped like a hook, and is the earliest lock in fact, namely the earliest knot, namely the earliest key in fact, namely the prototype of the lock in China. The product is used from the commercial generation to the Chinese generation, and then is made of jade, thus being developed into a decorative ornament on noble dress.

By the culture period of Yangshao of 5000 years to the present, the ancestors of China create wood locks mounted on wood frame buildings. This is the oldest lock in the world and may be referred to as the "world first lock". The wood lock is always inherited in folks, and like the white wood lock in the Ming dynasty, the wood lock is used on buildings in Zhejiang regions. Similar wood locks exist in today's world village of the Yi family of Kunming. Invar has entered the bronze era, but has not used copper to make large drinking, eating and sacrificial offerings, yet to make locks. The development period is from the Qin Han Wen south north to the sui Tang and Song Yuan in spring and autumn warring countries. After the invar bronze era, the times of spring and autumn enter the ironware era, and archaeology proves that a large number of people use iron locks, copper locks, silver locks, gilded locks and the like in the period, wherein representatives of the iron locks, the copper locks, the metal locks in east Han, the silver locks in the tail of shrimp in Tang dynasty, the square locks in Song dynasty and the like have quite high technical levels.

In particular, the iron three-spring lock in the Han Dynasty is used for more than 1000 years before and after China. The prosperous period is the Ming and Qing period, locks made of various materials are developed synchronously, copper locks and iron locks are used, the process is more exquisite, and great innovation is brought to unlocking difficulty and appearance manufacturing. Such as the Ming dynasty three-color copper lock, the Qing dynasty white crane lock, the coded lock, the concealed door lock, the four-way lock, the reverse pulling lock and the locks with various figures, animals and character shapes, the Linglan is full of eyes and is not good for harvest. Some locks have complex structures, ingenious design and peculiar organ, and are difficult to open by common people.

The lock with a complex structure is not suitable for doors and windows, but the lock with a too simple structure cannot play a role in locking the doors and windows. To this end, those skilled in the art have proposed an automatic door and window latch device to solve the problems set forth in the background above.
