Technical Field
[0001] This utility model relates to the field of security door technology, specifically to an anti-tailgating interlocking security door. Background Technology
[0002] Security doors are specialized doors used to protect buildings, areas, or facilities from unauthorized intrusion, fire, explosion, natural disasters, or other security threats. The core purpose of security door design is to enhance security, restrict unauthorized access, and provide protection. Depending on their application and environment, security doors come in various types, each with different functions and characteristics.
[0003] Being followed into a door by a user can lead to various potential drawbacks and harms, especially in places with high security requirements or confidential areas. The follower may take the opportunity to enter the restricted area and may carry out illegal activities, such as stealing data, damaging equipment, or causing other security problems. In response to the above problems, the inventor has proposed an anti-tailgating interlocking security door to solve the above problems. Summary of the Invention
[0004] To address the issue of tailgating in high-security or confidential areas, where individuals may attempt to enter restricted areas for illegal activities such as data theft, equipment damage, or other security breaches, this invention provides an anti-tailgating interlocking security door. By incorporating a rotating security door assembly, the door allows only individually verified individuals to enter. Combined with an identity verification system, unverified personnel cannot pass through the access control. This not only prevents tailgating but also ensures that each person must independently verify their identity before entry, reducing security vulnerabilities. The rotating door can be integrated into a security management system, recording each identity verification process. Entry and exit records and personnel flow can be monitored in real time, increasing the transparency of security management. The design of a fixed base with a fitting groove ensures the rotating security door can only rotate in one direction. This unidirectional rotation effectively prevents unauthorized individuals from tailgating into restricted areas. When an employee enters, the door can only rotate in one direction, preventing anyone from following before the door closes, ensuring only authorized personnel can enter.

The rotating safety door assembly includes a safety rotating door 11, a second gear 14, and an interlocking movable block 21. The safety revolving door 11 rotates inside the safety door body 1. The safety revolving door 11 can fit with the safety inner door 3. The second gear 14 rotates outside the upper fixed plate 2. A rotating base 15 is fixedly installed outside the safety revolving door 11. The fitting movable block 21 moves outside the rotating base 15.
[0023] The safety revolving door 11 has a main rotating shaft 12 fixedly installed on its exterior. The main rotating shaft 12 is fixedly connected to the rotating base 15. The safety door body 1 has a fixed base 16 fixedly installed on its exterior. The rotating base 15 is rotatably connected to the fixed base 16. The safety door body 1 has a fitting groove 19 on its exterior. The fitting movable block 21 can fit into the fitting groove 19.
[0024] By adopting the above technical solution, the movable block 21 can be fitted with the fitting groove 19, so that the rotating base 15 can only rotate in one direction.
[0025] A second rotating shaft 17 is fixedly installed on the outside of the fitting movable block 21. The second rotating shaft 17 is rotatably connected to the rotating base 15. A first spring 18 is fixedly installed on the outside of the fitting movable block 21. The end of the first spring 18 away from the fitting movable block 21 is fixedly connected to the rotating base 15.
[0026] By adopting the above technical solution, the end of the first spring 18 away from the fitting movable block 21 is fixedly connected to the rotating base 15, and the first spring 18 can be used to reset the fitting movable block 21.
[0027] A fixed ring 7 is fixedly installed on the outside of the upper fixed plate 2. A motor 4 is fixedly installed on the outside of the fixed ring 7. A rotating shaft 5 is rotatably connected to the outside of the motor 4. A gear 6 is fixedly installed on the outside of the rotating shaft 5. The gear 6 meshes with the gear 14.
[0028] By adopting the above technical solution, the No. 1 gear 6 meshes with the No. 2 gear 14, and the rotation of the No. 1 gear 6 can drive the rotation of the No. 2 gear 14.
[0029] The safety door body 1 has a sliding groove 10 on its outside. A sliding outer door 8 is slidably connected to the outside of the safety door body 1. A limit rod 9 is fixedly installed on the outside of the sliding outer door 8. The limit rod 9 is slidably connected to the sliding groove 10.
[0030] By adopting the above technical solution, the sliding outer door 8 can be limited by the limiting rod 9 and the sliding groove 10 through the sliding connection of the limiting rod 9.

[0032] By adopting the above technical solution, with two sets of ventilation and dustproof nets 20 and verification control center 13 symmetrically distributed, the safety door can be easily operated using the verification control center 13.
[0033] Working principle: When an anti-tailgating interlocking safety door is required, the sliding outer door 8 is opened to allow the user to enter the rotating base 15. Furthermore, the first motor 4 drives the first rotating shaft 5 to rotate, which in turn drives the first gear 6 to rotate, which in turn drives the second gear 14 to rotate. The second gear 14 then drives the safety rotating door 11 and the rotating base 15 to rotate, moving the user to the position of the verification control center 13. The verification control center 13 verifies the user's identity, allowing them to pass through the safety door. By setting up a revolving security door component, only one person can enter the revolving security door after their identity has been verified. After integrating an identity verification system with the revolving security door, unverified personnel cannot pass through the access control. This not only prevents tailgating but also ensures that everyone must verify their identity independently before entering, thereby reducing security vulnerabilities. The revolving door can be integrated into the security management system to record every identity verification process. Entry and exit records and personnel flow can be monitored in real time, increasing the transparency of security management. By designing a fixed base 16 that fits into a fitting groove 19, the rotating safety door can only rotate in one direction. The one-way rotating door can effectively prevent unauthorized people from entering the restricted area by tailgating. When an employee enters, the door can only rotate in one direction to prevent someone from following in before the door closes, ensuring that only authorized personnel can enter.
