Door lock is an extremely important part of life, literally means to lock the door, in order to prevent outsiders from opening the door casually and threatening our lives and property. Door locks have a long history in our country, as early as 5,000 years ago. However, with the development of society, the form of door locks is constantly changing, bringing a different experience to our lives. Let's take a look at the development history of door locks together.

1. Door latch

The oldest lock is a wooden lock mounted on a wooden structural frame, that is, a door latch. As long as it is inserted in the door, and then the door cannot be opened by sliding the latch, the door can be locked. The structure of this kind of door lock is simple and easy to make, but it is also easy to be damaged and easily affected by insects and mold. Even so, it can be seen in many places in life activities.

Two and three latches

Thanks to the application of bronze, door locks have developed well. Because the wooden lock is not strong enough and the confidentiality is not strong, it was later made of bronze, but the initial structure was simple and easy to open. In the Han Dynasty, a copper reed lock commonly known as a three-bolt lock appeared. It can be said that this is a qualitative leap in the development history of Chinese locks, and its confidentiality and security have been strengthened. Three latches have been used in China until the 1950s.

Three, marble lock

For marble locks, I believe this is an indispensable part of many people's childhood impressions. The pinball lock was invented by the American L. Yell in 1848 using a cylindrical pin. Since then, mankind has entered the modern lock era. The lock has been combined and arranged to make the lock number changed from the original 2500 types. Millions of types, thereby greatly improving the confidentiality and security performance of the lock, becoming the most commonly used lock in the world.

Four, sleeve turn core lock

Although the safety performance of the tumbler lock has been greatly improved, it is bulky and cumbersome to use. The tumbler lock is not the most ideal lock in life, so there is a later sleeve rotary lock. The sleeve-turn core lock can put the locking mechanism into a small-volume sleeve. Through the turning core as an intermediary, the control of the lock bolt by the transmission small key lays the foundation for the miniaturization of the lock.

Five, smart door lock

With the development of the times and the advancement of technology, electronic technology has also been applied to the field of door locks. A series of electronic door locks have appeared, such as magnetic locks, voice locks, ultrasonic locks, infrared locks, electromagnetic wave locks, electronic card locks, and fingerprints. Locks, eyeball locks, remote control locks, etc., these locks have high confidentiality performance and security unmatched by mechanical structures, and bring a different experience to people's lives.

Of course, in order to ensure the safety of smart door locks, it is inevitable to install an access control aluminum panel or aluminum alloy frame to protect the smart door lock from external forces, and it can also help the electronic components to dissipate heat. Function to build a safe environment for the intelligent access control system.

Zhigao Industry focuses on the production and processing of various aluminum alloy panels and shells. It can process and customize according to customers' drawings and samples, master a variety of surface treatment processes, and rely on senior experience to produce and process products with excellent performance and quality. The processing of intelligent access control panels is no exception, carefully casting so that what customers see is what they need.
