[0001] This utility model relates to the field of access control device technology, and in particular to a facial recognition anti-tailgating access control device. Background Technology
[0002] Facial recognition access control is an access control system based on facial recognition technology. It identifies and analyzes a person's facial features to determine whether to allow a person to enter a specific area, thereby controlling the opening and closing of the access control device.
[0003] In existing technologies, to ensure stability during the use of access control devices, the door can only slowly reset and close after a person enters. Some individuals, unable to be identified, may take advantage of this time gap to tailgate into the protected area, increasing security risks. Therefore, this invention designs a facial recognition anti-tailgating access control device. Utility Model Content
[0004] The purpose of this invention is to solve the problem that in the use of existing access control devices, in order to ensure stability, the access control device can only slowly reset and close after a person enters after the door is opened. Some people, because they cannot be identified, may take advantage of the time gap between the door's reset and closure to follow the identifiable person into the protected area of the access control, which will increase the security risks in the protected area. Therefore, a face recognition anti-tailgating access control device is proposed.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A facial recognition anti-tailgating access control device includes a chassis and a facial recognition panel. The facial recognition panel is fixedly connected to the upper surface of the chassis. A fixed shaft is fixedly connected inside the chassis. A sleeve is movably fitted on the shaft wall of the fixed shaft. A first baffle and a second baffle are fixedly connected to the sleeve wall. A rotating rod is rotatably connected inside the chassis. A gear is fixedly fitted on the rod wall. A motor is fixedly connected to the inner top wall of the chassis. The output shaft of the motor is fixedly connected to the rotating rod. Multiple teeth are fixedly connected around the sleeve wall. The gear meshes with the multiple teeth.
[0007] Preferably, the inner wall of the sleeve has a first cavity, a metal elastic strip is fixedly connected to the inner wall of the first cavity, a limit plug is fixedly connected to the end of the metal elastic strip, the inner wall of the fixed shaft has a second cavity, the inner wall of the fixed shaft in the second cavity has an insertion port, and the limit plug is inserted into the inner wall of the insertion port.
[0008] Preferably, the fixed shaft is slidably provided with a top block on the inner wall of the second cavity, and the top block is tightly abutted against the end of the limiting insert.
[0009] Preferably, a cylinder is fixedly connected to the inner wall of the bottom end of the second cavity, the inner wall of the second cavity is hinged with a movable plate, the upper and lower inner walls of the movable plate are respectively provided with sliding grooves, the inner walls of the two sliding grooves are respectively provided with sliders, and the piston rod end of the cylinder is hinged to the bottom of the lower slider.
[0010] Preferably, the top of the slider is hinged with a connecting rod, and the end of the connecting rod away from the slider is fixedly connected to the bottom of the top block.
[0011] Preferably, the cross-section of the slider is convex, and the movable plate is located on the inner wall of the groove and matches the slider.
[0012] Compared with the prior art, this utility model provides a face recognition anti-tailgating access control device, which has the following beneficial effects:
[0013] 1. This facial recognition anti-tailgating access control device uses the output shaft of a motor to rotate a rotating rod. The rotation of the rotating rod moves the gear teeth, causing the sleeve to rotate along the shaft wall of a fixed shaft. This causes the first and second baffles to swing, allowing the first baffle to open in time to allow personnel to pass through. At the same time, the second baffle follows the swing of the first baffle to close, preventing tailgating personnel from passing through the access control and reducing security risks.
[0014] 2. This face recognition anti-tailgating access control device, after the first and second baffles swing open and close, the sleeve is located inside the first cavity and aligned with the socket, so that the limiting plug can be pushed into the socket by the thrust of the metal elastic strip. This can improve the stability of the sleeve after rotation and prevent human intervention to swing the first and second baffles, which could damage the equipment.
[0015] 3. This face recognition anti-tailgating access control device uses a cylinder to pull the piston rod to move the lower slider and cause the movable plate to swing downward. At this time, the swing of the movable plate can cause the upper slider to slide along the inner wall of the slide groove, while pulling the connecting rod and the top block to move and push the limiting plug out to the outside of the socket, so that the limiting plug can retract into the inside of the first cavity without affecting the adjustment and rotation of the sleeve.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] Example 1
[0023] Reference Figure 1-4 A face recognition anti-tailgating access control device includes a housing 1 and a face recognition panel 17. The face recognition panel 17 is fixedly connected to the upper surface of the housing 1. A fixed shaft 2 is fixedly connected inside the housing 1. A sleeve 3 is movably sleeved on the shaft wall of the fixed shaft 2. A first baffle 4 and a second baffle 5 are fixedly connected to the sleeve wall of the sleeve 3. A rotating rod 6 is rotatably connected inside the housing 1. A gear 7 is fixedly sleeved on the rod wall of the rotating rod 6. A motor 8 is fixedly connected to the inner wall of the top of the housing 1. The output shaft of the motor 8 is fixedly connected to the rotating rod 6. Multiple teeth 9 are fixedly connected around the sleeve wall of the sleeve 3. The gear 7 and the multiple teeth 9 are meshed with each other.
[0024] The inner wall of the sleeve 3 has a first cavity, and a metal elastic strip 10 is fixedly connected to the inner wall of the first cavity. A limiting plug 11 is fixedly connected to the end of the metal elastic strip 10. The inner wall of the fixed shaft 2 has a second cavity, and the inner wall of the fixed shaft 2 in the second cavity has an insertion port. The limiting plug 11 is inserted into the inner wall of the insertion port. The fixed shaft 2 in the second cavity has a sliding top block 12, which is pressed against the end of the limiting plug 11.
[0025] In use, the face recognition panel 17 can identify personnel entering the area. When a qualified person needs to pass through the access control, the output shaft of the motor 8 rotates, which drives the rotating rod 6 to rotate. The rotation of the rotating rod 6 moves the gear 7, which moves the teeth 9, causing the sleeve 3 to rotate along the shaft wall of the fixed shaft 2. This causes the first baffle 4 and the second baffle 5 to swing, allowing the first baffle 4 to open in time to allow personnel to pass. At the same time, the second baffle 5 follows the swing of the first baffle 4 to close, which can prevent people from tailgating through the access control and reduce safety hazards. Also, when the first baffle 4 and the second baffle 5 are reset, the first baffle 4 will close in time when the second baffle 5 opens, which can also prevent people from entering the access control by mistake during the reset.
[0026] After the first baffle 4 and the second baffle 5 swing open and close, the sleeve 3 is located inside the first cavity and aligned with the socket, so that the limiting plug 11 can be pushed into the socket by the thrust of the metal elastic strip 10. This can improve the stability of the sleeve 3 after rotation and prevent the first baffle 4 and the second baffle 5 from swinging due to human intervention, which could damage the equipment.
[0027] Example 2
[0028] Reference Figure 1-4 A cylinder 13 is fixedly connected to the inner wall of the bottom end of the second cavity, and a movable plate 14 is hinged to the inner wall of the second cavity. The upper and lower inner walls of the movable plate 14 are respectively provided with sliding grooves, and sliders 15 are slidably provided on the inner walls of the two sliding grooves. The piston rod end of the cylinder 13 is hinged to the bottom of the lower slider 15, and a connecting rod 16 is hinged to the top of the upper slider 15. The end of the connecting rod 16 away from the slider 15 is fixedly connected to the bottom of the top block 12. The cross-section of the slider 15 is convex. The movable plate 14 is located on the inner wall of the sliding groove and matches the slider 15.
[0029] When a reset is required later, when the motor 8 is started, in order to prevent the limiting plug 11 from extending into the inside of the socket and affecting the timely rotation of the sleeve 3, the cylinder 13 can pull the piston rod to move, causing the lower slider 15 to move down and causing the movable plate 14 to swing down. At this time, the swing of the movable plate 14 can cause the upper slider 15 to slide along the inner wall of the groove, while pulling the connecting rod 16 and the top block 12 to move and push the limiting plug 11 out to the outside of the socket, so that the limiting plug 11 can retract into the inside of the first cavity and will not affect the adjustment and rotation of the sleeve 3.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
