[0025] Working principle: The utility model provides a rotatable security door. When in use, the person to be inspected enters the revolving door from the entrance end b. When entering the revolving door, he is in the detection part a. The driving device 5 drives the door shaft 6 to rotate, and the door panel 7 and the top price rotate accordingly. The person to be inspected moves along with the rotation of the door panel 7. The metal detector 10 set on the top frame 9 keeps detecting during the period before the person to be inspected reaches the exit end c. If no metal is detected and the person passes directly, the driving module of the gate rotating shaft 13 receives the signal of the metal detector 10, and opens when qualified. The baffles 14 on both sides move away from each other to facilitate the passage of people. After a person passes, the rotating shaft 13 will rotate to make the baffles 14 close together. On the contrary, when the metal detector 10 detects metal, it also outputs a signal to the driving module of the rotating shaft 13. The driving module stops the rotation of the rotating shaft 13, so that the baffles 14 on both sides are close to block people from entering and exiting. At the same time, the metal detector 10 sends a signal to the alarm 11, and the alarm 11 sounds an alarm to remind the staff. The utility model detects one person at a time by setting two relative detection parts a. Other people cannot enter the revolving door before the detection is completed. A detection interval is formed between the people to be inspected, ensuring that the detection will not be interfered with, thereby improving the detection accuracy. The utility model detects one person passing through by setting a gate, forming an obstacle for people to be inspected carrying metal, making it convenient to identify problem people.
