Chain lock for door controller: double guarantee of safety and convenience

In today's era when technology is changing with each passing day, the safety protection measures at home and office are constantly updated to better meet the needs of modern society. Among them, electronic access control system is widely used because of its high efficiency and convenience. This paper will focus on a product that combines traditional mechanical structure and modern intelligent technology-door controller supporting chain lock, and discuss its application scenarios and advantages.

I. Product Overview

Chain lock for door controller is a new type of door lock device which controls mechanical chain by electric drive to realize switch function. It not only has the basic anti-theft performance of ordinary chain locks, but also can be connected with all kinds of intelligent access control management systems, which can provide users with more flexible and diverse access management schemes while improving safety.

Second, the working principle

1. Motor drive: When the user triggers the door opening instruction by swiping the card or inputting the password, the internal micro motor starts to operate to drive the gear set to move;

2. Gear transmission: the gear set transmits power to the spindle through a series of precise fit, which makes the sprocket fixed on it rotate;

3. Lock body action: As the sprocket rotates, the metal chains connected at both ends are tightened or loosened, thus completing the whole unlocking process. In addition, in order to ensure the stable and reliable operation of the equipment, auxiliary components such as limit switches are usually equipped to monitor the chain position information in real time and adjust the travel range in time.

Third, the application field

(1) The installation of such equipment at the entrance and exit of the corridor of residential quarters can effectively prevent outsiders from entering and leaving at will and ensure the safety of residents' lives and property;

(2) The elevator hall of the underground garage of the commercial building is provided with a special passage to facilitate employees' commuting and restrict visitors from entering the core area;

(3) The closed management of school dormitory area is helpful to maintain good campus order and students' personal safety;

(4) It is even more essential to strengthen the construction of security facilities in important places such as government agencies, banks and financial institutions ...

Fourth, advantage analysis

Compared with the traditional manual opening and closing mode, the combination of "door controller+chain lock" undoubtedly has the following obvious advantages:

1. The operation is simple and easy to learn: you can quickly master the use method without complicated training, which greatly improves the work efficiency;

2. High safety factor: the built-in multiple anti-pry design can effectively resist violent sabotage and reduce the risk of theft;

3. Strong management flexibility: support multiple rights allocation strategies to meet the needs of different occasions;

4. Low maintenance cost: modular components are used to easily replace damaged parts and reduce the burden of long-term operation and maintenance expenses.

V. Conclusion

In a word, the door controller supporting chain lock, as an innovative scientific and technological achievement integrating practicality and aesthetics, is gradually becoming an indispensable and important part in many scenarios. I believe that with the progress of technology and the growth of market demand, more similar excellent works will be born in the future to serve consumers!
