Description

Technical Field

[0001] This utility model relates to the field of security technology, and in particular to a security gate with a blocking structure. Background Technology

[0002] Security gates, also known as metal detectors, are common security screening devices widely used in airports, train stations, subway stations, stadiums, and large event venues. They are primarily used to detect whether people are carrying metal objects, ensuring the safety of public areas. People typically need to walk through them at a normal pace. When a metal object is detected, an alarm signal is emitted through sound and light to alert security personnel for further verification. The process is relatively convenient and does not cause harm to the human body. It can quickly complete the initial security screening without affecting the normal passage efficiency of people, helping to eliminate potential security risks and maintain public order and personal safety.

[0003] In the field of public security inspection, traditional venues often need to promptly intercept individuals carrying prohibited items. Traditional interception methods mostly rely on manual intervention, which has a slow response speed and is prone to untimely interception. Some automatic interception devices have complex structures and are prone to rigid contact with personnel during the interception process, which may cause accidental injury. In addition, the buffer protection effect of the interception components is not good, and they are prone to damage due to frequent collisions after long-term use. At the same time, the stability and durability of the interception mechanism need to be improved, making it difficult to meet the needs of efficient and safe security inspection and interception. Therefore, a security gate with a barrier structure is needed. Utility Model Content

The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.

[0021] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0022] Please see Figure 1-4 This utility model provides a technical solution: a security gate with a barrier structure, wherein: The security frame 1 is the core support structure of the entire security gate. Its surface needs to be fixedly connected to the security gate body 2, the detection probe 3 and the protective shell 5. Its bottom is fixed to the support base 4. The support base 4 is made of high-strength cast iron, which can provide stable support for the security frame 1, prevent the security gate from shaking during use, and ensure the stability of the overall structure.

[0023] The main body 2 of the security gate is fixed to the surface of the security frame 1, and together with the security frame 1, they form a passage for personnel. Its inner side is adapted to the position of the detection probe 3, which can guide personnel to pass through the detection area in a standardized manner. The main body 2 of the security gate is made of lightweight alloy material, which reduces the overall weight while ensuring structural strength, making it easy to install and transport.

[0024] The detection probe 3 is installed on the surface of the security frame 1 and corresponds to the passage of the security gate body 2. It is used to detect whether the person passing through is carrying metal objects. The detection probe 3 is made of high-sensitivity sensor chip material, which can quickly and accurately identify metal objects. When an abnormality is detected, it can trigger the interception and protection mechanism to reduce the situation of missed detection and false detection.

[0025] The protective shell 5 is fixed to the surface of the security frame 1. The interior is a hollow structure that encloses the toothed plate 7, hydraulic cylinder 9, guide plate 10 and gear 11. The protective shell 5 is made of flame-retardant ABS plastic material, which can effectively isolate external dust and moisture, protect internal components from corrosion, and prevent personnel from accidentally touching moving parts and causing safety hazards.

[0026] The hydraulic cylinder 9 is fixed on the surface of the security frame 1 and located inside the protective shell 5. Its output end is fixedly connected to the toothed plate 7. The hydraulic cylinder 9 is made of high-pressure sealed rubber material, which can stably output thrust and provide continuous power for the sliding of the toothed plate 7, ensuring a rapid response to the interception action and avoiding insufficient power that could lead to interception delay.

[0027] The guide plate 10 is fixed on the surface of the security frame 1 and is inside the protective shell 5. The toothed plate 7 is slidably connected to the guide plate 10. The guide plate 10 is made of wear-resistant stainless steel. When the toothed plate 7 slides, it can restrict its movement direction to prevent the toothed plate 7 from deviating and causing misalignment with the gear 11, thus ensuring smooth operation of the transmission structure.

[0028] The toothed plate 7 is slidably connected to the surface of the security frame 1 and located inside the protective shell 5. The limiting plate 8 is fixedly connected to the surface. The toothed plate 7 is made of high-strength quenched steel and meshes with the gear 11. When the hydraulic cylinder 9 pushes the toothed plate 7 to slide, it can drive the gear 11 to rotate. At the same time, the limiting plate 8 slides along the slide groove 6 of the protective shell 5 to limit the range of motion of the toothed plate 7.

[0029] The slide groove 6 is formed on the surface of the protective shell 5 and is adapted to the limiting plate 8 on the toothed plate 7. The slide groove 6 is smooth and polished, which can reduce the frictional resistance when the limiting plate 8 slides, and prevent the limiting plate 8 from getting stuck and affecting the movement of the toothed plate 7. At the same time, the cooperation between the limiting plate 8 and the slide groove 6 prevents the toothed plate 7 from sliding excessively and damaging the components.

[0030] The limiting plate 8 is fixed on the surface of the toothed plate 7 and is slidably connected to the slide groove 6 of the protective shell 5. The limiting plate 8 is made of wear-resistant alloy material. In addition to limiting the movement range of the toothed plate 7 in conjunction with the slide groove 6, it can also enhance the structural strength of the toothed plate 7, prevent the toothed plate 7 from bending and deforming due to long-term stress, and extend the service life of the toothed plate 7.

[0031] Gear 11 is rotatably connected to the surface of security frame 1 and located inside the protective housing 5. The central shaft passes through security frame 1 and is fixed to rotating arm 12. Gear 11 is made of high-strength gear steel and meshes with toothed plate 7. When toothed plate 7 slides, it can drive gear 11 to rotate, thereby driving rotating arm 12 to rotate synchronously, realizing the power transmission of interception action.

[0032] The rotating arm 12 is rotatably connected to the surface of the security frame 1. One end is fixed to the gear 11 via the central shaft of the gear 11. The surface is fixedly connected to the buffer pad 13 and the interception bracket 14. The rotating arm 12 is made of lightweight and high-strength aluminum alloy. Driven by the gear 11, it can quickly rotate to the interception position, providing basic support for subsequent interception.

[0033] The cushioning pad 13 is fixed to the surface of the rotating arm 12. It is made of high-elasticity sponge wrapped with wear-resistant fabric. When the rotating arm 12 intercepts, the cushioning pad 13 can directly contact the personnel to absorb the impact force during the interception, avoid the personnel from being injured by rigid collision with the rotating arm 12, and improve the safety of the interception process.

[0034] The interception bracket 14 is fixed on the surface of the rotating arm 12, and the buffer protection component 15 is slidably connected to the surface. Multiple buffer springs 16 arranged in a linear array are also fixed thereon. The interception bracket 14 is made of stainless steel and can provide installation support for the buffer protection component 15 and the buffer springs 16, while also enhancing the interception strength of the rotating arm 12.

[0035] The buffer protection component 15 is slidably connected to the surface of the interception bracket 14. It can be a rectangular bar with chamfers or a circular column with a protective sleeve. It is made of elastic plastic material. When it comes into contact with personnel during interception, it works with the buffer spring 16 to further absorb the impact force and prevent personnel injury. At the same time, the chamfer or protective sleeve design can reduce the risk of scratching during contact.

[0036] Multiple buffer springs 16 are fixed to the surface of the interceptor bracket 14 in a linear array. One end is fixed to the buffer protection component 15. They are made of high-strength carbon steel and have good elastic recovery performance. When the buffer protection component 15 is impacted, it can be compressed and deformed to absorb energy. After the impact, it quickly resets to ensure the buffering effect of the next interception.

[0037] The limit block 17 is fixed on the surface of the security frame 1 and is made of rubber-coated metal. When the rotating arm 12 rotates to the interception position, the rotating arm 12 will contact the limit block 17. The limit block 17 can limit the maximum rotation angle of the rotating arm 12 to prevent the rotating arm 12 from being damaged due to excessive rotation. At the same time, the rubber material can reduce collision noise and wear during contact.

[0038] Working principle: The detection probe 3 will detect personnel passing through the security frame 1 and the main body of the security gate 2. If an abnormality is detected, the blocking function needs to be activated. The hydraulic cylinder 9 will push the toothed plate 7, which is fixedly connected to it, and slide along the inside of the protective shell 5 under the guidance of the guide plate 10. Since the toothed plate 7 meshes with the gear 11, the sliding of the toothed plate 7 will drive the gear 11 to rotate. The central axis of the gear 11 passes through the security frame 1 and is fixedly connected to the rotating arm 12. Therefore, the rotation of the gear 11 will cause the rotating arm 12 to rotate around the security frame 1. During the rotation, the buffer pad 13 and the interception bracket 14 on the surface of the rotating arm 12 will move accordingly. The buffer spring 16 on the interception bracket 14 will work with the buffer protection component 15 to play a buffer protection role to avoid contact with personnel and cause injury. The limiting plate 8 on the surface of the toothed plate 7 will slide along the slide groove 6 on the surface of the protective shell 5 to limit the range of motion of the toothed plate 7. Finally, the rotating arm 12 will contact the limiting block 17 on the surface of the security frame 1 to stop the rotation and complete the blocking.

[0039] Example 1: (Reference) Figure 2 ) The buffer protection component 15 is a rectangular rod with chamfered edges. This component is slidably connected to the surface of the interceptor bracket 14, and one end is fixed to the buffer spring 16.

[0040] The rectangular bar structure increases the contact area with the interception bracket 14. Combined with the elastic effect of the buffer spring 16, it can more evenly disperse the impact force during interception. The chamfered design can prevent the corners from scratching people's clothing or skin.

[0041] Meanwhile, the rectangular bar is made of elastic plastic, which combines hardness and toughness. It is not easily deformed during long-term use and can stably cooperate with the rotating arm 12 and the buffer pad 13 to complete the interception action, thereby improving the safety and durability of airport security interception and ensuring the comfort of passengers during passage.

[0042] Example 2: (Reference) Figure 4 ) Replace the buffer protection component 15 with a circular column fitted with a protective sleeve. This component is also slidably connected to the surface of the interceptor bracket 14 and connected to the buffer spring 16.

[0043] The smooth surface of the cylindrical column, combined with the soft material of the protective cover, further reduces friction when in contact with people, minimizing discomfort even if people are stopped while quickly passing through the security gate.

[0044] In addition, the circular column structure facilitates sliding on the interception bracket 14, and with the quick reset function of the buffer spring 16, the recovery time after interception can be shortened, which can meet the needs of high passenger flow and high security check frequency in subway stations and improve the overall security check efficiency.

[0045] Example 3: (Reference) Figure 1-4 ) The rectangular rod-shaped buffer protection component 15 with chamfered corners is suitable for scenarios such as airports and high-speed rail stations where people carry a lot of luggage. When people carry luggage through the channel formed by the security frame 1 and the main body of the security gate 2, if the interception is triggered, the rotating arm 12 drives the interception bracket 14 to move. Under the action of the buffer spring 16, the rectangular rod-shaped buffer protection component 15 only contacts the people. Its chamfered design can prevent the corners from scratching the people's clothing. The rectangular rod structure can work with the buffer pad 13 to more evenly distribute the interception impact force, preventing people from being injured by contact with the component when they lose their balance due to carrying luggage. At the same time, it does not touch the luggage, avoiding affecting the normal placement of the luggage or causing the luggage to shift, and ensuring the stability of the people and luggage during security interception.

[0046] The circular cylindrical buffer protection component 15, fitted with a protective sleeve, is suitable for densely populated scenarios such as schools and gymnasiums, where pedestrians are the main group of people. People have no luggage or only carry small personal items. When the detection probe 3 detects an anomaly, the hydraulic cylinder 9 pushes the toothed plate 7, which drives the gear 11 to rotate the rotating arm 12. The circular cylindrical buffer protection component 15 slides on the interception bracket 14. In conjunction with the buffer spring 16 and the buffer pad 13, it can directly contact people with a soft protective sleeve. The smooth circular cylindrical surface reduces the feeling of friction during contact. Especially for the elderly and children, it can minimize the discomfort of contact during interception. Since it does not come into contact with luggage, there is no need to consider the impact of luggage on the component, allowing more focus on personnel protection. It meets the high requirements for personnel safety and comfort in such scenarios.

[0047] Both types of buffer protection components 15 can stably cooperate with the security frame 1, rotating arm 12, interception bracket 14 and other structures. In their respective applicable scenarios, they not only achieve efficient personnel protection through their own characteristics, but also avoid the interference of luggage with the interception action because they do not come into contact with luggage, ensuring that the interception and protection mechanism always operates stably. At the same time, the protective shell 5 protects the internal toothed plate 7, guide plate 10 and other components, and the support base 4 ensures the stability of the overall structure, further improving the adaptability and reliability of the security gate in different scenarios.

[0048] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
