Description

Technical Field

[0001] This application relates to the field of well detection technology, specifically to an intelligent access control structure for entrances and exits. Background Technology

[0002] Many current intelligent access control systems employ a structural design combining fixed brackets with movable barriers to achieve automated control of entrances and exits. A typical solution involves installing fixed brackets on both sides of the passageway, with a strip-shaped barrier (such as a swing gate or wing gate structure) that can rotate around a horizontal axis between the brackets. This barrier is usually driven by a motor, and upon recognizing an authorized access signal (such as card swiping, facial recognition, or QR code verification), it rotates to open the passageway; after the pedestrian has passed, it resets to the blocking state.

[0003] However, the above structure presents certain safety hazards in some scenarios: Sometimes, after pedestrians input their identification signal into the access control system, they may walk forward before the system returns a correct recognition signal. If the system recognizes the signal correctly, the barrier will open as expected, and the pedestrian's movement will generally not be hindered. However, if the access control system malfunctions due to reasons such as light interference, obstruction causing facial / QR code recognition failure, or sensor failure, the barrier will remain closed and will not open. In this situation, some pedestrians cannot anticipate the barrier's state and are prone to violent collisions with the rigid barrier while passing through. Such collisions may cause limb contusions, property damage, or even secondary injuries such as falls, affecting the pedestrian's experience and safety when entering and exiting. Utility Model Content

[0004] In view of the problem that existing access control structures are prone to causing physical injury when pedestrians collide with them, this utility model provides an intelligent access control structure for entrances and exits.

[0005] Therefore, the specific technical solution adopted by this utility model is as follows:

[0006] This utility model provides an intelligent access control structure for entrances and exits, characterized in that it includes:

[0007] The fixing frame consists of two sets arranged at intervals. Each fixing frame has a through hole and a rotating shaft is rotatably mounted within the through hole. A baffle plate is fixedly mounted on the rotating shaft.

[0008] The mounting bracket has sliding grooves at both the upper and lower ends of the through hole. Mounting blocks are slidably installed in the sliding grooves. Each end of the rotating shaft passes through a set of mounting blocks. Limiting strips are fixedly installed at both ends of the rotating shaft. A limiting groove matching the limiting strips is provided along the length direction of the sliding groove. A fixing rod is fixedly installed at one end of the mounting block. A groove matching the fixing rod is provided on the side wall of the sliding groove. A spring is sleeved on one end of the fixing rod in the sliding groove. The two ends of the spring are connected to the mounting block and the side wall of the sliding groove, respectively.

[0009] It also includes an adjustment mechanism, which is mounted on the fixed frame.

[0010] Preferably, the adjusting mechanism includes an adjusting rod, a rack, a turntable, and a geared disc. A set of sliding grooves at the bottom has a countersunk hole at the end furthest from the groove. The turntable is embedded in the countersunk hole. The top of the turntable has a second limiting groove that mates with the first limiting groove. A geared disc is fixedly mounted at the bottom of the turntable and is rotatably connected to a fixed frame. The fixed frame has an mounting groove, and the adjusting rod is slidably mounted in the mounting groove. One end of the adjusting rod is fixedly mounted with a rack that meshes with the geared disc. The initial position of the limiting bars at both ends of the rotating shaft when not impacted is within the second limiting groove of the turntable. At this time, the first limiting groove and the limiting groove are in the same position. The two slots are connected. When the barrier plate is impacted, it can drive the limiting strip to slide along the limiting slot one and the limiting slot two. The rotating shaft is coaxial with the turntable. When pedestrians pass through after the access control system recognizes them normally, the adjusting rod in the adjusting mechanism drives the rack to slide along the mounting slot. The meshing of the rack and the gear plate causes the gear plate and the turntable to rotate when the rack slides, thereby driving the limiting strip and the rotating shaft to rotate. Finally, the barrier plate is rotated into the through hole, so that the passage is open and it is convenient for pedestrians to walk. After the pedestrians have passed, the adjusting rod drives the turntable and the rotating shaft to return to their original positions.

[0011] Preferably, an electric push rod is fixedly installed in the mounting slot. The output shaft of the electric push rod is fixedly connected to one end of the adjusting rod. After a pedestrian is successfully identified at the access control point, the access control system starts the electric push rod, and the output shaft of the electric push rod drives the adjusting rod to slide.

[0012] Preferably, the fixing rods are arranged in multiple sets at intervals on the mounting block. The multiple sets of fixing rods limit the mounting plate at multiple points, ensuring the stability of the mounting plate sliding in the groove. At the same time, the springs set on the multiple sets of fixing rods improve the strength of the barrier plate to withstand collisions.

[0013] Preferably, a protective plate is fixedly installed on the top of the mounting block, and the rotating shaft passes through the protective plate. The bottom of the protective plate abuts against the top opening of the slide groove. During the sliding of the mounting block along the slide groove, the protective plate always abuts against and covers the opening of the slide groove, preventing the fixed rod and spring inside the slide groove from being directly exposed to the outside, and preventing external objects from falling into the slide groove and causing obstruction or damage when the spring is compressed, thereby improving the safety of the equipment.

[0014] Preferably, buffer plates are bonded to both sides of the barrier plate. The buffer plates are elastic and can provide cushioning protection when a pedestrian collides with the barrier plate, reducing the injury to the pedestrian.

[0015] Preferably, an alarm is fixedly installed on the top of the fixed frame, and a distance sensor is fixedly installed at the end of the groove away from the fixed rod. When the barrier plate is hit and the rotating shaft and mounting block slide, the fixed rod slides along the groove. At this time, the distance sensor monitors the distance between the fixed rod and the distance sensor. When the detected value changes beyond the set range, the distance sensor sends an electrical signal to the access control system. Then, the access control system activates the alarm, which sounds an alarm to alert security personnel to check and pay attention to the pedestrian equipment after the collision.

[0016] The advantages of adopting the above technical solution are:

[0017] This utility model includes a fixed frame with a through hole. A rotating shaft is rotatably mounted on the fixed frame within the through hole, and a barrier plate is fixedly mounted on the rotating shaft. The fixed frame has sliding grooves at both the upper and lower ends of the through hole, and mounting blocks are slidably mounted within these grooves. Each end of the rotating shaft passes through a set of mounting blocks, and limit strips are fixedly mounted at both ends of the rotating shaft. A limit groove matching the limit strips is provided along the length of the sliding groove. A fixing rod is fixedly mounted at one end of each mounting block, and a spring is sleeved on one end of the fixing rod within the sliding groove. When the access control system malfunctions and a pedestrian collides with the barrier plate, the barrier plate drives the rotating shaft and mounting blocks to slide along the sliding groove, thereby preventing a rigid direct collision between the pedestrian and the barrier plate and ensuring the safety of the pedestrian during the collision.

[0027] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0028] like Figure 1-7 As shown in the figure, this utility model embodiment discloses an intelligent access control structure for entrances and exits, including a fixed frame 1 and an adjustment mechanism. The fixed frame 1 consists of two sets arranged at intervals. The fixed frame 1 has a through hole. A rotating shaft 2 is rotatably installed in the fixed frame 1 within the through hole. A barrier plate 201 is fixedly installed on the rotating shaft 2. The fixed frame 1 has a sliding groove 101 at both the upper and lower ends of the through hole. An installation block 3 is slidably installed in the sliding groove 101. Each end of the rotating shaft 2 passes through a set of installation blocks 3. Limiting strips 202 are fixedly installed at both ends of the rotating shaft 2. A limiting groove 102 that matches the limiting strip 202 is provided along the length direction in the sliding groove 101. A fixing rod 301 is fixedly installed at one end of the installation block 3. A groove 104 that matches the fixing rod 301 is provided on the side wall of the sliding groove 101. A spring 302 is sleeved on a section of the fixing rod 301 within the sliding groove 101. The two ends of the spring 302 are respectively connected to the installation block 3 and the side wall of the sliding groove 101. The adjustment mechanism is installed on the fixed frame 1.

[0029] In at least one embodiment, the adjusting mechanism includes an adjusting rod 6, a rack 601, a turntable 4, and a gear plate 402. A set of sliding grooves 101 at the bottom has a countersunk hole at the end furthest from the groove 104. The turntable 4 is embedded in the countersunk hole. The top of the turntable 4 has a second limiting groove 401 that matches the first limiting groove 102. The bottom of the turntable 4 is fixedly provided with a gear plate 402, which is rotatably connected to the fixing frame 1. The fixing frame 1 has an installation groove 103. The adjusting rod 6 is slidably disposed in the installation groove 103. One end of the adjusting rod 6 is fixedly provided with a rack 601 that meshes with the gear plate 402. The initial position of the limiting bars 202 at both ends of the rotating shaft 2 when not impacted is within the second limiting groove 401 of the turntable 4. At this time, the first limiting groove 102 and the limiting... The second groove 401 is connected. After the barrier plate 201 is impacted, it can drive the limiting strip 202 to slide along the limiting groove 102 and the limiting groove 2 401, ensuring that the rotating shaft 2 can slide and reset normally. The rotating shaft 2 is coaxial with the turntable 4. When pedestrians pass through after the access control is recognized normally, the adjusting rod 6 in the adjusting mechanism drives the rack 601 to slide along the mounting groove 103. The meshing of the rack 601 and the gear plate 402 causes the rack 601 to drive the gear plate 402 and the turntable 4 to rotate when it slides, thereby driving the limiting strip 202 and the rotating shaft 2 to rotate. Finally, the barrier plate 201 is rotated into the through hole, so that the passage is in an open state, which is convenient for pedestrians to walk. After the pedestrians have passed through, the adjusting rod 6 drives the turntable 4 and the rotating shaft 2 to return to their original positions.

[0030] In at least one embodiment, an electric push rod 5 is fixedly installed in the mounting groove 103. The output shaft of the electric push rod 5 is fixedly connected to one end of the adjusting rod 6. After a pedestrian is successfully identified at the access control point, the access control system starts the electric push rod 5, and the output shaft of the electric push rod 5 drives the adjusting rod 6 to slide.

[0031] In at least one embodiment, the number of fixing rods 301 is multiple sets and spaced apart on the mounting block 3. The multiple sets of fixing rods 301 limit the mounting plate at multiple points to ensure the stability of the mounting plate sliding in the slide groove 101. At the same time, the springs 302 provided on the multiple sets of fixing rods 301 improve the strength of the barrier plate 201 to withstand collisions.

[0032] In at least one embodiment, a protective plate 7 is fixedly provided on the top of the mounting block 3, and the rotating shaft 2 passes through the protective plate 7. The bottom of the protective plate 7 abuts against the top opening of the slide groove 101. During the sliding of the mounting block 3 along the slide groove 101, the protective plate 7 always abuts against and covers the opening of the slide groove 101, so as to prevent the fixed rod 301 and spring 302 inside the slide groove 101 from being directly exposed to the outside, and to prevent external objects from falling into the slide groove 101 and causing obstruction or damage when the spring 302 is compressed, thereby improving the safety of the equipment.

[0033] In at least one embodiment, buffer plates are bonded to both sides of the barrier plate 201. The buffer plates are elastic and can provide buffer protection when a pedestrian collides with the barrier plate 201, thereby reducing the injury to the pedestrian.

[0034] In at least one embodiment, an alarm is fixedly installed on the top of the mounting bracket 1, and a distance sensor 105 is fixedly installed at the end of the groove 104 away from the fixed rod 301. When the barrier plate 201 is impacted and the rotating shaft 2 and the mounting block 3 slide, the fixed rod 301 slides along the groove 104. At this time, the distance sensor 105 measures the distance between one end of the fixed rod 301 and the distance sensor 105. The access control system records and monitors the measured value. When the measured value exceeds the set range, the access control system sends an electrical signal, and then the access control system activates the alarm. The alarm sounds an alarm to alert security personnel to check and pay attention to the pedestrian equipment after the collision.

[0035] In at least one embodiment, an access control system is installed on the fixed frame 1. The access control system includes an identification device 8 fixedly installed on the top of the fixed frame 1. The identification device 8 can be of the type of facial recognition, fingerprint recognition, or card recognition. The identification device 8 has a control terminal inside. The identification device 8 is electrically connected to an external power source through a wire. The electric push rod 5, the distance sensor 105, and the alarm are all electrically connected to the control terminal. After the identification device 8 successfully identifies the user, it sends a start signal to the control terminal to start the electric push rod 5. The control terminal can continuously record the monitoring data of the distance sensor 105. When the detection data of the distance sensor 105 exceeds the set range, the alarm is activated to sound an alarm to remind the staff.

[0036] When pedestrians enter or exit this access control structure, a recognition device 8 is fixedly installed on the fixed frame 1. The recognition device 8 can use facial recognition, card swiping recognition, etc. The pedestrian is identified when approaching the passage of the access control structure. When the recognition device 8 successfully recognizes the pedestrian, the adjusting mechanism executes the rotation of the rotating shaft 2, thereby causing the rotating shaft 2 on both sets of fixed frames 1 to drive the barrier plate 201 to rotate and retract into the through hole, allowing the pedestrian to pass through the passage. After passing through, the adjusting mechanism drives the rotating shaft 2 to rotate and reset, causing the barrier plate 201 to block the passage. When the recognition device 8 fails to recognize the pedestrian, the pedestrian approaches the barrier plate 201 from the passage. When the pedestrian's body comes into contact with the barrier plate 201, the barrier plate 201, after being squeezed by the body, drives the rotating shaft 2 and the mounting block 3 to slide along the length direction of the slide groove 101. The limiting strips 202 at both ends of the rotating shaft 2 are embedded in the limiting grooves 102 in the slide groove 101, thereby controlling the rotation. The shaft 2 and the barrier plate 201 are limited, so that when the barrier plate 201 is squeezed, it drives the rotating shaft 2 to slide along the limiting groove 102. At the same time, when the mounting plate slides, it drives the fixing rod 301 to slide along the groove 104. When the fixing rod 301 slides, the mounting block 3 compresses the spring 302 sleeved on the fixing rod 301. When the pedestrian and the barrier plate 201 no longer collide, the spring 302 squeezes the mounting block 3, driving the mounting block 3 and the rotating shaft 2 to return to their original positions. This ensures that the identification device 8 can perform normal opening and closing operations on the barrier plate 201 after normal identification. In addition, the sliding of the barrier plate 201 during the collision avoids the pedestrian from directly colliding with the barrier plate 201, reducing the collision intensity at the time of contact and reducing the risk of physical and equipment injury caused by the rigid collision between the pedestrian and the barrier plate 201. At the same time, the barrier plate 201 remains in a blocking state during the collision, preventing unauthorized personnel from forcibly entering and exiting, and has the function of blocking the passage.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
