Password linkage drawer lock is a kind of safety device which combines traditional mechanical structure with modern password technology. It is widely used in filing cabinets or drawers in offices, families and other places to protect the safety of personal belongings and important materials. This paper will introduce its working principle, characteristics and application scenarios.

First, the working principle

Password setting:

Users can set an unlocking password composed of numbers (generally 46 digits). These numbers are transformed into physical unlocking actions through a series of gears and linkage mechanisms.

Unlocking process:

When the user inputs the correct password, a set of internal precision mechanisms will move the components in sequence according to the preset order, and finally the locking mechanism will be opened, thus realizing the function of keyless unlocking.

Second, the main features

1. High security: due to the complicated mechanical structure and password combination, it is more difficult to crack compared with the traditional key lock.

2. Good convenience: you can complete the opening and closing operation without carrying a physical key, and support the setting of multiple sets of spare passwords, and you can open it smoothly when you forget the master password.

3. Wide application range: not only suitable for all kinds of furniture drawers, safes and other fields, but also particularly convenient in some cases where users need to be changed frequently.

4. Easy installation and maintenance: Most models are designed to be very compact and lightweight, and detailed installation guides and technical support services are provided.

Third, typical application cases

1. Office environment: Enterprises often need to keep sensitive information confidential, and the password linkage drawer lock can help them effectively control the access rights of confidential documents;

2. Educational institutions: valuable instruments in school libraries or laboratories can also be equipped with such equipment to strengthen management;

3. Home life: The storage space of personal items such as home filing cabinets and jewelry boxes also benefits from the convenience and security brought by such smart locks.

In a word, the password connecting rod drawer lock has been widely used in many fields with its unique advantages, and has gradually become an indispensable part of people's daily life. With the continuous improvement of science and technology and the increasing demand of consumers, I believe there will be more innovative products in the future to meet more diverse demand scenarios.
