Description

Technical Field

[0001] This utility model relates to the field of turnstile technology, specifically a turnstile for preventing tailgating and queue-jumping. Background Technology

[0002] Turnstiles are typically used in places where people need to be controlled and accessed, such as entrances and exits of subway stations, high-speed rail stations, and airports.

[0003] Chinese utility model patent CN215252518U discloses an anti-tailgating device for pedestrian turnstiles. The device includes a turnstile body. A first rotating shaft is rotatably connected to one side of the inner wall of the turnstile body via a bearing. A first wing plate is fixed to one end of the first rotating shaft. A second rotating shaft is rotatably connected to the inner wall of the turnstile body away from the first wing plate via a bearing. A second wing plate is fixed to one end of the second rotating shaft. Symmetrical through slots are provided on one side of the turnstile body. This utility model patent uses a servo motor to drive the first and second wing plates to open and close alternately, thereby preventing tailgating and queue cutting. However, when pedestrians have a lot of luggage, the space between the first and second wing plates cannot accommodate a large amount of luggage. The luggage will block the first wing plates, and when the first and second wing plates alternate, the first wing plates will squeeze the luggage, causing it to get stuck between the first wing plate and the ground, making passage impossible and reducing the practicality of this utility model patent.

[0004] Therefore, this utility model provides a gate that prevents tailgating and queue-jumping. Utility Model Content

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Please see Figures 1 to 6 This utility model provides a technical solution: a gate for preventing tailgating and queue-jumping, comprising a gate body 1, an anti-tailgating mechanism 2, and a gate 3. The anti-tailgating mechanism 2 includes a first mounting groove 6, a mounting plate 9, a gear 10, and an adjusting rod 11. The adjusting rod 11 is rotatably mounted inside the first mounting groove 6 via a shaft symmetrically arranged at one end. The gear 10 is positioned on one side of the mounting plate 9 at a position corresponding to the tooth 12 via a first servo motor 21. The gate 3 includes a rotating rod 15, a U-shaped frame 18, a crossbar 17, and a rotating tube 19. A second mounting groove 8 is provided on the side wall at the rear end of the gate body 1. The rotating rod 15 is rotatably mounted inside the front end of the second mounting groove 8. The crossbar 17 is symmetrically fixed at both ends of the rotating rod 15. The two ends of the U-shaped frame 18 are movably connected to the crossbar 17 through the L-shaped plate 20. The meshing action between the gear 10 and the teeth 12 facilitates the rotation adjustment of the adjusting rod 11, making it easy to rotate the adjusting rod 11 from a vertical state to a horizontal state. Furthermore, the first mounting groove 6 and the adjusting rod 11 are located at the top of the gate body 1, which can reduce the impact on luggage, allowing pedestrians to move luggage and preventing luggage from being squeezed, thus improving the practicality of the gate.

[0024] In this embodiment, the first mounting groove 6 is formed on the side wall at the top of the gate body 1, corresponding to the front side of the second mounting groove 8. The first buffer pad 13 and the second buffer pad 14 are fixedly installed on the inner bottom wall and side wall of the first mounting groove 6, respectively. The adjusting rod 11 is arranged between the first buffer pad 13 and the second buffer pad 14. The first mounting groove 6 facilitates the storage of the adjusting rod 11, making it convenient for pedestrians to pass through. The first buffer pad 13 and the second buffer pad 14 can buffer the adjusting rod 11, reducing the noise generated by the mutual impact between the adjusting rod 11 and the gate body 1.

[0025] In this embodiment, the mounting plate 9 is fixedly installed inside the top of the gate body 1. A first servo motor 21 is fixedly installed on the front side of the bottom end of the mounting plate 9. The gear 10 is fixedly installed on the output shaft of the first servo motor 21. A circular tooth 12 is fixedly provided on the outer wall of one end of the adjusting rod 11. The gear 10 and the tooth 12 are meshed with each other. The gear 10 and the first servo motor 21 are located inside the gate body 1. The first servo motor 21 drives the gear 10 to rotate. The meshing action between the gear 10 and the tooth 12 adjusts the adjusting rod 11, making it convenient to open and close the anti-tailgating mechanism 2, and to prevent pedestrians from tailgating and cutting in line.

[0026] In this embodiment, a second servo motor 16 is fixedly installed inside the bottom end of the gate body 1 at the position corresponding to the rotating rod 15. The output shaft of the second servo motor 16 is fixedly connected to the bottom end of the rotating rod 15. The L-shaped plate 20 is fixedly installed at one end of the crossbar 17. A torsion spring shaft is fixedly installed on one side of each end of the U-shaped frame 18. The torsion spring shaft is rotatably installed inside the other end of the L-shaped plate 20. The rotating tube 19 is rotatably installed on the outside of the middle section of the U-shaped frame 18. One end of the crossbar 17 is located inside the second mounting groove 8. The bottom of the gate body 1... An infrared detection sensor 7 is fixedly installed on the side wall of the end near the lower part of the anti-tailgating mechanism 2. The second servo motor 16 and the rotating rod 15 can rotate the crossbar 17 and the U-shaped frame 18, so that the gate 3 enters the interior of the second mounting groove 8, which facilitates pedestrian passage. The torsion spring shaft and the L-shaped plate 20 can block and limit one side of the U-shaped frame 18, so that the U-shaped frame 18 can only rotate backward, preventing pedestrians from being pinched and improving the safety of the gate. The infrared detection sensor 7 can detect the position of pedestrians, which facilitates the subsequent opening of the anti-tailgating mechanism 2 and the gate 3.

[0027] In this embodiment, a card reader 4 is fixedly installed on the front top of the gate body 1 on one side, and a face recognition device 5 is fixedly installed on the rear side of the card reader 4. The card reader 4 is located on one side of the first mounting slot 6. The card reader 4 and the face recognition device 5 facilitate pedestrian verification, allowing pedestrians to pass through the gate.

[0028] When using this anti-tailgating gate, the gate body 1 is equipped with a controller. The card reader 4 and the face recognition device 5 are electrically connected to the controller. Encoders are installed on the first servo motor 21 and the second servo motor 16 and are electrically connected to the controller. The encoders control the two first servo motors 21 and the two second servo motors 16 to rotate synchronously at the same speed. The gate is fixedly installed at the entrance / exit channel, and the controller is electrically connected to an external power supply. When a pedestrian swipes their card with the card reader 4 or is identified by the face recognition device 5, the controller and encoder control the two first servo motors 21 to rotate synchronously at the same speed. The first servo motor 21 drives the adjusting rod 11 to rotate upward through the meshing action between the gear 10 and the teeth 12, and enters the interior of the first mounting slot 6, allowing the pedestrian to pass through the anti-tailgating mechanism 2. After the infrared detection sensor 7 detects a pedestrian, it controls the first servo motor 21 to drive the gear 10 and the teeth 12 to rotate, turning the adjusting rod 11 downward from a vertical state to a horizontal state, preventing other pedestrians from following. Two second servo motors 16 are activated. These motors, via a rotating rod 15, drive the crossbar 17 and U-shaped frame 18 to rotate into the second mounting slot 8, facilitating the opening of the gate 3 and allowing pedestrian passage. Since the adjusting rod 11 rotates downwards and is positioned at the top of the gate body 1, it minimizes the impact on luggage. Pedestrians can also move their luggage between the gate bodies 1, avoiding obstruction of others' passage and improving the device's practicality. After passing through the gate 3, pedestrians are guided by the second servo motors 16 and the rotating rod... 15. The crossbar 17 and the U-shaped frame 18 are rotated out from the inside of the second mounting slot 8; the U-shaped frame 18 is movably connected to the crossbar 17 through the L-shaped plate 20 via a torsion spring shaft, and the U-shaped frame 18 is provided with a rotating tube 19, which allows the U-shaped frame 18 to rotate backward via the torsion spring shaft to prevent pedestrians from being pinched and to improve the safety of the access gate. Under normal conditions, the U-shaped frame 18 and the crossbar 17 are set in the same plane under the torque of the torsion spring shaft. The infrared detection sensor 7 is a Hyman HS8MLS intelligent human infrared sensor.
