[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The utility model is provided with a lifting seat at the front end of one of the automatic doors, and an identification seat is provided in front of the lifting seat. When a passer-by needs to pass through the automatic door, the facial information can be collected by a facial information collector, and the facial information collector can send the facial information data to the controller for processing and comparison. When it meets the requirements, the dual-axis motor can be started to rotate, and the dual-axis motor can drive the two first threaded rods to rotate, so that the two moving blocks can move in opposite or opposite horizontal straight lines. When the two moving blocks move in opposite directions, the automatic door will be driven to open, thereby facilitating the entry of passers-by. When it does not meet the requirements, the dual-axis motor will not rotate, thereby playing a role of safety protection and preventing unauthorized persons from entering.

[0017] 2. The utility model is provided with a second threaded rod which is rotatably arranged inside the lifting seat. When performing face recognition, it is inevitable that short passers-by may not be able to collect faces well. At this time, the handle can be turned to enable the lifting block to drive the recognition seat to adjust the height up and down, so that it can be adjusted according to the height of different passers-by, taking into account the needs of different groups of people, especially for shorter children or shorter adults who may not be able to collect effective facial information at a conventional height, ensuring that every passer-by can collect facial information smoothly, and the operation is simple and convenient, which is convenient for daily use.

[0018] 3. The utility model provides a buffer plate on the inner side of the automatic door, and a buffer spring between the buffer plate and the automatic door. When the automatic door is closed, safety accidents such as pinching the hand may occur. By providing the buffer plate made of silicone, the impact force when the automatic door is closed can be effectively absorbed and dispersed. At the same time, when the buffer plate is squeezed, the buffer spring will be squeezed synchronously to further absorb and disperse the impact force, thereby achieving effective buffering and improving safety.

[0028] When in use, the facial information of passers-by can be collected through the facial information collector 15 at the front end of the recognition seat 13. When the facial information of the passers-by matches the facial information pre-stored in the controller 16, the controller 16 will start the dual-axis motor 7, thereby driving the two moving blocks 8 to move in opposite directions, so that the automatic door 2 is opened to facilitate the passage of passers-by. When the facial information of the passers-by does not match the facial information pre-stored in the controller 16, the dual-axis motor 7 will not be started, thereby preventing unauthorized persons from passing through and playing a role in safety protection.

[0032] See also Figure 1 A guide rod 6 is welded directly above the first threaded rod 5. The guide rods 6 all penetrate the moving block 8, and the guide rods 6 all slide with the moving block 8. The guide rods 6 can limit the moving block 8, so that the rotation of the moving block 8 can be converted into horizontal linear movement, thereby driving the automatic door 2 to move;

[0033] See also Figure 2 A slide groove 12 is provided at the rear of the second threaded rod 10, and the slide groove 12 is slidably matched with the lifting block 11. The slide groove 12 can axially limit the lifting block 11, so that the rotation of the lifting block 11 can be converted into vertical movement up and down, so that the height of the identification seat 13 can be adjusted;

[0034] See also Figure 2 and Figure 4 A display screen 14 is provided at the lower side of the front end of the recognition seat 13 , and the input end of the display screen 14 is electrically connected to the output end of the controller 16 . The display screen 14 can feed back the facial information collected by the face information collector 15 .

[0035] Working principle: When in use, the passerby can grasp the handle 20 and rotate it, the handle 20 will drive the second rotating shaft 19 to rotate, the second rotating shaft 19 will drive one of the bevel gears 18 to rotate synchronously, because the two bevel gears 18 are meshed and connected, so it will drive the other bevel gear 18 to make the first rotating shaft 17 rotate synchronously, the first rotating shaft 17 will drive the second threaded rod 10 to rotate synchronously, the second threaded rod 10 will drive the lifting block 11 to rotate synchronously, because the lifting block 11 and the slide groove 12 slide together, so the rotation of the lifting block 11 will be limited by the axial direction, the rotation of the lifting block 11 will be converted into vertical movement up and down, and the passerby can pass through. By turning the handle 20 clockwise or counterclockwise, the lifting block 11 can be adjusted, and the lifting block 11 will drive the recognition seat 13 to move synchronously, so that the recognition seat 13 can be adjusted to a position horizontal to the face of the user, so that the face information collector 15 can fully collect the face of the user to avoid affecting the recognition. The face information collector 15 will send the face information to the controller 16. When the face information of the passer-by matches the face information pre-stored in the controller 16, the controller 16 will start the dual-axis motor 7. The dual-axis motor 7 will drive the two first threaded rods 5 to rotate through the coupling, and the first threaded rods 5 will both drive The movable blocks 8 rotate synchronously. Since the movable blocks 8 are slidably matched with the guide rods 6, the movable blocks 8 are all axially limited. The rotation of the two movable blocks 8 is converted into opposite or opposite horizontal linear movements, so that when the movable blocks 8 move in opposite directions, they will drive the automatic door 2 to move synchronously, thereby facilitating the passage of passers-by. When the facial information of the passers-by does not match the facial information pre-stored in the controller 16, the dual-axis motor 7 will not be started, thereby preventing unauthorized persons from passing through and playing a role in safety protection. When the automatic door 2 is closed, if the hands or other body parts of the passers-by are in the door gap at this time, the buffer plate 2 1 can effectively absorb and disperse the impact force when the automatic door 2 is closed. When the automatic door 2 contacts the buffer plate 21, the buffer plate 21 will be elastically deformed, thereby slowing down the speed of the automatic door 2 and gradually stopping it. At the same time, buffer springs 22 are provided. These buffer springs 22 are made of high-strength steel and have good elasticity and fatigue resistance. When the automatic door 2 contacts the buffer plate 21, the buffer springs 22 will also be compressed to further absorb and disperse the impact force. As the automatic door 2 continues to close, the buffer springs 22 will gradually release the stored energy, so that the automatic door 2 stops smoothly at the closed position, avoiding the occurrence of safety accidents such as pinching hands.
