Description

Technical Field

[0001] This utility model belongs to the field of security gate technology, specifically relating to an intelligent multi-zone security gate alarm device. Background Technology

[0002] Security checks are a mandatory procedure for all personnel entering rail transit systems. They are an important preventative measure to ensure passenger safety. The main purpose of rail transit security checks is to inspect passengers' personal belongings and luggage for dangerous items such as firearms, ammunition, explosives, corrosive substances, toxic substances, and radioactive materials, in order to ensure the safety of the subway and its passengers. When checking passengers, they are usually asked to pass through security gates to detect whether they are carrying any metal objects.

[0003] The existing technology includes a multi-zone alarm security gate with patent publication number CN221546516U. This patent, through its relative movement and lifting mechanisms, allows the gate to be lowered for easy maintenance. The locking mechanism allows for easy disassembly by holding both handles with one hand. However, in practical use, it has the following shortcomings: The security gate primarily uses magnetic field induction to detect metal objects on the entire body of pedestrians. After detecting metal objects, staff still need to use a handheld security scanner to further confirm their presence and location, increasing workload and reducing throughput.

[0004] Therefore, there is a need for an intelligent multi-zone security gate alarm device to solve the problem that existing technologies require staff to use handheld security scanners to further confirm the presence and location of metal items, which not only increases workload but also reduces security check efficiency.

[0022] The present invention will be further described below with reference to the embodiments.

[0023] Please see Figure 1-4 This utility model provides an intelligent multi-zone security gate alarm device, including a security gate body 1, a housing 2, a pedal 3, a pressure sensor 4, a lifting mechanism 5, a detection mechanism 6, and an alarm 7. The housing 2 is located inside the upper part of the security gate body 1, the pedal 3 is located inside the lower part of the security gate body 1, the pressure sensor 4 is located inside the upper part of the pedal 3, the lifting mechanism 5 is symmetrically arranged above the security gate body 1, the detection mechanism 6 is located below the lifting mechanism 5, and the alarm 7 is located on the front of the housing 2.

[0024] Further as Figure 1 , Figure 3 and Figure 4As shown, it is worth noting that the lifting mechanism 5 consists of a fixed plate 501, a lifting motor 502, a connecting shaft 503, a winding reel 504, a rope 505, and a moving block 506. The fixed plate 501 is symmetrically fixedly connected to the top of the security gate body 1. The lifting motor 502 is fixedly connected to one side of the fixed plate 501. The connecting shaft 503 is rotatably connected between the two fixed plates 501, and the connecting shaft 503 is fixedly connected to the output end of the lifting motor 502. The winding reel 504 is fixedly connected to the outside of the connecting shaft 503.

[0025] Further as Figure 1 , Figure 3 and Figure 4 As shown, it is worth noting that the rope 505 is wound around the outside of the reel 504, the moving block 506 is fixedly connected to the bottom end of the rope 505, and the moving block 506 is slidably connected to the inside of the security gate body 1.

[0026] By controlling the forward and reverse rotation of the lifting motor 502, the winding reel 504 can be wound or unwound, thereby driving the detection mechanism 6 below to move up and down, performing two inspections on the user and improving the accuracy of the inspection.

[0027] Further as Figure 1 , Figure 3 and Figure 4 As shown, it is worth noting that the detection mechanism 6 consists of a moving ring 601, an L-shaped ring 605, a limiting ring 606, a gear block assembly 607, a fixed shaft 608, a gear 609, a rotary motor 610, a connecting column 611, and a detection head 612. The moving ring 601 is fixedly connected between two moving blocks 506. The moving ring 601 has an installation cavity 602 inside. A limiting groove 603 is opened on one side of the installation cavity 602. An opening 604 is opened at the bottom of the installation cavity 602. The L-shaped ring 605 is located inside the installation cavity 602. The limiting ring 606 is fixedly connected to the outside of the L-shaped ring 605, and the size of the limiting ring 606 is adapted to the limiting groove 603.

[0028] As can be seen from the above working process, the lifting mechanism 5 can control the lower detection mechanism 6 to rise and fall smoothly and slowly, thereby improving the stability of the detection mechanism 6 and further improving the accuracy of the detection effect.

[0029] Further as Figure 1 , Figure 3 and Figure 4 As shown, it is worth noting that the tooth block assembly 607 is located inside the L-shaped ring 605, the fixed shaft 608 is symmetrically rotated and connected to the left and right sides below the top surface of the mounting cavity, and the gear 609 is fixedly connected to the outside of the fixed shaft 608, and the gear 609 meshes with the tooth block assembly 607.

[0030] The rotation of the gear 609 drives the gear block assembly 607 to rotate, which in turn drives the L-shaped ring 605 to rotate inside the mounting cavity. This, in turn, drives the detection head 612 to rotate via the connecting column 611 below, enabling 360-degree detection of the user and improving the comprehensiveness of the detection.

[0031] Further as Figure 1 , Figure 3 and Figure 4 As shown, it is worth noting that the rotary motor 610 is fixedly connected above the moving ring 601, and the top end of the right fixed shaft 608 is fixedly connected to the output end of the rotary motor 610. The connecting column 611 is symmetrically fixedly connected around the bottom surface of the L-shaped ring 605, and the detection head 612 is fixedly connected to the bottom surface of the connecting column 611. The connecting column 611 rolls inside the L-shaped ring 605.

[0032] Further as Figure 1 , Figure 3 and Figure 4 As shown, it is worth noting that the pressure sensor 4 is electrically connected to the lifting motor 502, and the detection head 612 is electrically connected to the alarm 7.

[0033] When pressure is detected on pressure sensor 4, the lifting motor 502 can be controlled to operate, driving the detection mechanism 6 to lift and lower to detect the user. When a metal object is detected, the detection head 612 sends a signal to the alarm 7, which then alerts the staff to handle the situation, thus improving the intelligence of the device.

[0034] This solution operates as follows: When in use, the user steps on the pedal 3. The pressure sensor 4 receives the pressure and sends a signal to the lifting motor 502. The lifting motor 502 drives the connecting shaft 503 to rotate, which in turn drives the winding reel 504 to unwind the rope 505. The moving block 506 moves the detection mechanism 6 downward, and at the same time, the rotary motor 610 starts, driving the right fixed shaft 608 to rotate. The right gear 609 meshes with the gear block group 607, driving the L-shaped ring 605 to rotate. This, in turn, drives the detection head 612 below to rotate via the connecting column 611. As the moving ring 601 descends, it performs a 360-degree detection of the user. When a metal object is detected, the detection head 612 sends a signal to the alarm 7, which then alerts the staff to handle the situation.

[0035] In summary: The lifting mechanism 5 allows the detection mechanism 6 below to rise and fall smoothly and slowly, thereby improving the stability of the detection mechanism 6 and further enhancing the accuracy of the detection results; the detection mechanism 6 also controls the rotation of the detection head 612 during its lifting and lowering process, enabling 360-degree detection of personnel and accurately locating the position of metal objects, thus improving detection efficiency while ensuring the comprehensiveness and accuracy of security checks.
