Technical Field

[0001] This utility model relates to the field of entrance and exit gate technology, specifically an entrance and exit gate for preventing tailgating. Background Technology

[0002] With the increasing development of urban rail transit, public transportation stations, and high-security locations, entrance and exit turnstiles, as crucial facilities for controlling passenger flow and ensuring safety, have received widespread attention for their performance and reliability. Traditional single-gate or simple rotary turnstiles are significantly inadequate in preventing tailgating, especially during peak hours when tailgating is frequent, disrupting operational order and potentially posing safety hazards. Furthermore, a malfunction in a single-structure turnstile often paralyzes the entire access route, making repairs difficult and impacting efficiency.

[0003] To address these issues, various improved turnstiles have emerged on the market, incorporating intelligent auxiliary technologies such as infrared sensors and video surveillance. However, these solutions largely rely on external equipment, increasing system complexity and cost, and may fail under certain conditions (such as network instability or power failure). Furthermore, existing anti-tailgating designs in mechanical structures are often limited to single-plane interception, failing to achieve comprehensive, three-dimensional protection.

[0004] Therefore, it is necessary to propose an entry and exit gate system to prevent tailgating. Utility Model Content

[0005] In view of the shortcomings of the prior art, this utility model provides an entry and exit gate that prevents tailgating. It has the advantages of effectively preventing tailgating, high reliability, and easy maintenance, thus overcoming the defects of the prior art mentioned in the background.

[0006] This utility model provides the following technical solution: a station gate for preventing tailgating, comprising a right gate body, a mounting sleeve, a gate, and a left gate body. The right gate body and the left gate body form a pedestrian passage. The mounting sleeve is disposed inside the right gate body. A motor is installed on the inner top of the right gate body, and the output end of the motor is fixedly connected to a rotating shaft. The mounting sleeve is fitted onto the surface of the rotating shaft. The gate is disposed inside the mounting sleeve. A triangular movable seat is disposed on the inner top of the left gate body. A motor is installed inside the triangular movable seat, and the output end of the motor is fixedly connected to a turntable. Three gate rods are fixedly connected to the surface of the turntable, and the three gate rods are arranged circumferentially about the surface of the turntable.

[0007] Preferably, a contraction slit is provided on one side of the mounting sleeve, and the mounting sleeve is fastened to the surface of the rotating shaft by fastening bolts.

[0008] Preferably, one side of the gate is rotatably connected to the inside of the mounting sleeve, and a plurality of springs are fixedly connected to the inner wall of the mounting sleeve, with the other end of the springs fixedly connected to the side of the gate.

[0009] Preferably, two insert rods are slidably inserted into one end of the gate away from the mounting sleeve, and an extension plate is fixedly connected to the other end of the insert rod. A second fastening bolt is threaded onto the surface of the gate, and the end of the second fastening bolt is tightly abutted against the side of the insert rod.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This type of anti-tailgating entrance and exit gate employs a dual-gate system: a right gate and a left gate, forming a closed pedestrian passage. A dual dynamic interception structure is created through rotating gates and rotary gate arms, achieving mechanically linked anti-tailgating control. The gate on the right gate rotates and opens / closes along its axis, while the triangular moving seat on the left gate drives three gate arms to rotate synchronously at 135° intervals, forming a staggered passage control that effectively prevents tailgating or crawling. The mounting sleeve connects to the rotating shaft via a contraction joint, and combined with fastening bolts, allows for quick assembly, disassembly, and fine-tuning, adapting to different shaft sizes while ensuring gate rotation concentricity. The gate's built-in spring-loaded flexible connection to the mounting sleeve buffers external impacts and reduces long-term wear. Its plug-in extension plate covers the bottom gap, enhancing anti-crawling capability. The triangular moving seat uses locking blocks and slots for sliding positioning, and a threaded rod adjusts its horizontal position, ensuring the gate arm assembly adapts to different gate spacings. The gate arms on the rotary table extend the interception range via extension rods, forming a continuously rotating three-dimensional protective barrier, significantly improving system operational stability.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Reference Figures 1-4As shown, an entry / exit gate for preventing tailgating includes a right gate body 100, a mounting sleeve 200, a gate 300, and a left gate body 400. The right gate body 100 and the left gate body 400 form a pedestrian passage. The mounting sleeve 200 is located inside the right gate body 100. A motor is installed on the inner top of the right gate body 100, and the output end of the motor is fixedly connected to a rotating shaft 101. The mounting sleeve 200 is fitted onto the surface of the rotating shaft 101. The gate 300 is located inside the mounting sleeve 200. A triangular movable seat 500 is provided on the inner top of the left gate body 400. A motor is installed inside the triangular movable seat 500, and the output end of the motor is fixedly connected to a turntable 600. Three gate arms 601 are fixedly connected to the surface of the turntable 600, and the three gate arms 601 are arranged circumferentially about the surface of the turntable 600. The system employs a dual-gate system: a right gate body 100 and a left gate body 400 form a closed pedestrian passage. A dual dynamic interception structure is created through a rotating gate 300 and gate arms 601. When pedestrians pass through, the gate 300 of the right gate body 100 rotates along the pivot 101 to open and close. The triangular movable seat 500 of the left gate body 400, in conjunction with the turntable 600, drives the three gate arms 601 to rotate synchronously, forming a staggered passage control system. This structure effectively prevents tailgating through mechanical linkage, and the dual-channel design avoids system paralysis due to a single gate failure.

[0028] Preferably, the mounting sleeve 200 has a contraction slot 201 on one side, and the mounting sleeve 200 is securely fitted onto the surface of the rotating shaft 101 by a fastening bolt 202. The mounting sleeve 200 is fitted onto the rotating shaft 101 through the contraction slot 201, and quick assembly and disassembly are achieved using the fastening bolt 202. The design of the contraction slot 201 allows the mounting sleeve 200 to be finely adjusted axially to adapt to rotating shafts 101 of different specifications, while the fastening bolt 202 provides a stable connection, ensuring the concentricity of the gate 300 during rotation and reducing mechanical wear.

[0029] In a further preferred embodiment, one side of the gate 300 is rotatably connected to the interior of the mounting sleeve 200. Several springs 203 are fixedly connected to the inner wall of the mounting sleeve 200, and the other end of each spring 203 is fixedly connected to the side of the gate 300. The gate 300 is flexibly connected to the mounting sleeve 200 via the springs 203. When the gate 300 is subjected to an external impact, the springs 203 can absorb the impact energy, preventing structural damage caused by a rigid collision between the gate 300 and the mounting sleeve 200. The elastic support of the springs 203 also reduces fatigue wear from the long-term reciprocating rotation of the gate 300, extending its service life.

[0030] In a further preferred embodiment, two insert rods 301 are slidably inserted into one end of the gate 300 away from the mounting sleeve 200. An extension plate 302 is fixedly connected to the other end of each insert rod 301. A second fastening bolt 303 is threaded onto the surface of the gate 300, with the end of the second fastening bolt 303 tightly abutting against the side of the insert rod 301. The gate 300 is inserted into the extension plate 302 via the insert rods 301 and fixed by the second fastening bolt 303. The effective length of the gate 300 can be adjusted according to the actual channel width. The insertion structure facilitates disassembly and maintenance, and the extension plate 302 can cover the gap between the gate 300 and the ground, preventing personnel from crawling under and enhancing anti-tailgating reliability.

[0031] In a further preferred embodiment, the triangular movable seat 500 is triangularly shaped, and the gate arm 601 is positioned at a 135-degree angle relative to the surface of the turntable 600. An extension rod 602 is slidably inserted into the end of the gate arm 601, and a fastening bolt 603 is threaded onto the surface of the gate arm 601, with the end of the fastening bolt 603 tightly abutting against the side of the extension rod 602. The triangular movable seat 500 is slidably engaged with the slot 402 of the left gate body 400 via a locking block 501, and locked in place by the nut 503 of the threaded rod 502, achieving rapid positioning of the triangular movable seat 500. The three gate arms 601 on the turntable 600 are distributed at 135° intervals, and the interception range can be expanded via the extension rod 602, forming a continuously rotating three-dimensional protective barrier that effectively prevents tailgating individuals from approaching.

[0032] In a further preferred embodiment, a locking block 501 is fixedly connected to the top of the triangular movable seat 500, and a threaded rod 502 is fixedly connected to the side of the triangular movable seat 500. A nut 503 is threaded onto the surface of the threaded rod 502. A slot 402 is formed in the inner top wall of the left gate body 400, and the locking block 501 is slidably engaged with the slot 402. A through groove 401 is formed in the side wall of the left gate body 400, and the threaded rod 502 is slidably engaged with the through groove 401. The threaded rod 502 of the triangular movable seat 500 passes through the through groove 401 of the left gate body 400. The horizontal position of the triangular movable seat 500 can be adjusted by the nut 503 to adapt to different gate bodies: the right gate body 100 and the left gate body 400. The sliding engagement between the locking block 501 and the slot 402 ensures that the triangular movable seat 500 can only move along a preset trajectory, preventing deviation that could cause the gate arm 601 to rotate and interfere, thus improving the stability of the system operation.
