The door is the first barrier to entry, which is an important barrier to prevent dangerous individuals from entering and ensure the safety of family members and property. The quality of the door lock is the most critical indicator for measuring the safety of the door. How to choose the safest door lock? Let the editor tell you.

Introduction to general classification of door locks starting from scratch

The history of locks is very long, basically born at the same time as private ownership. After thousands of years of development, locks have evolved from simple door latches and wooden locks to common spring locks, electronic locks, and so on. I believe that with the advancement of technology, more locks with higher security will continue to emerge. So, at this stage, what are the locks we can choose from? Let's get a brief understanding together first.

1. General classification of common locks

Many locks have been phased out due to low security, and their presence can only be seen in museums. Nowadays, the more common locks are divided into two types: ball mechanical locks and electronic intelligent locks. Pinball lock is currently the most commonly used lock in the world, while smart lock is a new type of lock that has emerged with the development of electronic technology and is the direction of future lock development, with a continuously increasing market share.

Editor's reminder: There is no absolutely safe lock in the world. Anti unlocking and unlocking technology are like spears and shields, both of which are constantly advancing and developing. The mechanical lock feels quite practical and has a lower price; Smart locks are the development direction of locks in modern society, with high security and convenient operation. However, there are also some disadvantages, and consumers need to consider multiple factors before making a choice.

Introduction to Two Ball Locks

Mechanical locks are not just limited to pin locks, but currently most mechanical locks use pin lock structures. There are several holes distributed radially on the surface of the pin lock cylinder, which correspond to the holes on the lock body and ensure necessary concentricity. These holes are filled with two rows of cylindrical pins, namely the upper pin and the lower pin. In general, the upper pin in the lock body hole is inserted into the lock cylinder hole, or the lower pin in the lock cylinder is inserted into the lock body hole, so that the lock cylinder cannot rotate freely.

After the correct key is inserted into the pin lock, the tooth pitch of the key corresponds to the hole of the pin one by one, and the tooth depth corresponds to the length of the lower pin. Therefore, the contact surface between the upper pin and the lower pin coincides with the contact surface between the lock core and the lock body, and the lock core can rotate freely, driving the mechanism to achieve switch action.

Introduction to 3 Smart Locks

Smart locks refer to locks that are more intelligent in terms of user identification, security, and management, different from traditional mechanical locks. Smart locks are made using electronic technology, integrated circuit design, a large number of electronic components, and various innovative identification technologies.

At present, there are three main types of smart locks: password locks, induction locks, and biometric locks. With the maturity of products, smart locks are gradually entering a large number of ordinary households.

The biggest security vulnerability of smart locks

Smart locks generally require electricity or batteries to operate, and if there is a power outage or other situation, the smart lock cannot be opened or closed. Therefore, according to national regulations, civilian smart locks should be equipped with emergency mechanical keys, and product quality standards are mainly based on the "Public Safety Industry Standard of the People's Republic of China (GA701-2007)". Emergency keys are usually ordinary mechanical pin locks, so smart locks can also be technically opened, resulting in a corresponding decrease in safety.
