Description

Technical Field

[0001] This invention relates to the field of security, and more specifically, to access control and security monitoring systems. Background Technology

[0002] Access control refers to the restriction of access to a door, serving as a means of security and prevention. In a broad sense, "door" here includes all kinds of passageways, such as doors for pedestrians and doors for vehicles.

[0003] Existing access control systems generally use image recognition, which cannot accurately identify pedestrians when people are wearing masks.

[0004] Chinese patent CN114627585A discloses a smart community access control system. It uses a voiceprint receiving module to receive the voice of the resident to determine whether to open the automatic door. During the epidemic prevention period, residents do not need to remove their masks for facial recognition, which reduces the spread of the epidemic. It uses a liquid pump to draw a certain amount of disinfectant and atomizes the disinfectant with a misting module to disinfect the cyclone disinfection protective cover, which reduces the transmission route of the virus and improves safety.

[0005] Although the aforementioned patent uses a voiceprint receiving module to receive the owner's voice to control the automatic door opening and closing, electric vehicles also pass through the access control system. Furthermore, the access control door rotates relatively slowly, so when people in a hurry, such as delivery personnel, pass through, the side of the vehicle may easily bump into or scratch the door, which could easily damage the access control system. Summary of the Invention

[0006] To address the problems existing in the prior art, the purpose of this invention is to provide an access control security monitoring system that uses impact to detach the connecting column from the motor box. When the motor box rotates, it will not cause the connecting column to rotate, and consequently, it will not cause the revolving door to rotate. When the revolving door encounters an impact, it will not cause the connecting column to be impacted and rotate, thereby causing the output shaft of the motor box to rotate and resulting in damage to the motor.

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] The access control and security monitoring system includes a revolving door. An image recognition component is provided on the left side of the revolving door. A motor box is fixedly connected to the top left side of the revolving door. A side plate is fixedly connected to the top left side of the revolving door. A drive component is slidably connected inside the side plate. A connecting column is slidably connected inside the side plate to the left of the drive component. An installation cavity is provided inside the side plate. A connecting column is used to connect to the motor box. The rotation of the motor box's output shaft rotates the connecting column, and the rotation of the connecting column controls the rotation of the revolving door. The top of the connecting column extends to form a limiting block, the limiting block extends into the interior of the motor box, a connecting rod is fixedly connected to the bottom of the connecting column, a third spring is welded to the bottom edge of the connecting column, and a disc is fixedly connected to the bottom of the connecting rod. A driving component is used to drive the connecting column to move, so that the connecting column is disengaged from the motor box, and the rotation of the revolving door is no longer restricted by the motor box. The bottom of the drive component is fixedly connected to a first pressure plate, and the inside of the side plate is provided with a second moving groove corresponding to the displacement direction of the first pressure plate. The left side of the first pressure plate is in contact with the top of the disc.

[0009] Furthermore, a protective mechanism is provided at the front end of the revolving door. The protective mechanism includes a fixing frame fixed to the surface of the revolving door, and a pressing plate is slidably connected to the side of the fixing frame. The rear end of the pressing plate extends into the interior of the side plate.

[0010] Furthermore, the front top of the drive member is provided with an extrusion groove, the cross-sectional shape of the extrusion groove is a right trapezoid, the left side of the drive member extends to form a slider, and the interior of the side plate is provided with a third moving groove to accommodate the movement of the slider.

[0011] Furthermore, the right side of the extrusion plate extends to form a first extension block, and a through groove is provided inside the fixing frame corresponding to the position of the first extension block. Multiple cylinders are fixedly connected inside the extrusion plate, the cylinders penetrate the side plate, and a first spring is welded to the surface of the cylinder.

[0012] Furthermore, a third extension block extends from the bottom of both sides of the connecting column, and the third extension block is slidably connected to the inside of the side plate.

[0013] Furthermore, a hollow column is provided inside the side plate. The top of the hollow column passes through the side plate and is fixedly connected to the motor box. A bearing is movably connected between the bottom of the hollow column and the side plate. The inner wall of the hollow column is in contact with the outer surface of the connecting column and the motor box.

[0014] Furthermore, an oil storage box is slidably connected to the inside of the side plate on the outer surface of the hollow column, and a second spring is welded to the bottom of the oil storage box, the second spring being in a naturally extended state.

[0015] Furthermore, a sponge block is fixedly connected to the bottom of the oil reservoir. The cross-sectional shape of the sponge block is circular, and the sponge block is located directly above the inner ball bearing.

[0016] Furthermore, the oil storage box has an oil storage cavity inside to hold lubricating oil, and the bottom of the inner cavity of the oil storage box has a plurality of circular holes arranged in a ring array, all of which are located directly above the sponge block.

[0017] Furthermore, the left side of the drive unit extends to form a second pressure plate, the left side of the second pressure plate is above the oil storage box, the side of the oil storage box extends to form a second extension block, and the interior of the revolving door is provided with a first moving groove corresponding to the position of the second extension block.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This solution achieves the separation of the connecting column from the motor box through impact. When the motor box rotates, it will not cause the connecting column to rotate, and thus will not cause the revolving door to rotate. When the revolving door is impacted, the connecting column will not be impacted and rotate, which will cause the output shaft of the motor box to rotate and damage the motor. The rotation of the revolving door will not be affected by the motor box and the connecting column. After the revolving door is impacted, it will rotate on its own through the rotational connection between the revolving door and the device frame, which can further reduce the impact force.

[0019] 2. In this solution, during the movement of the extrusion plate, the extrusion plate moves inside the side plate with the first spring. The extrusion plate is squeezed by the first spring, and the extrusion groove is squeezed and then moves the driving component downward. The movement of the driving component can be achieved by impact, making the movement of the driving component more convenient.

[0020] 3. This solution uses the movement of the extrusion plate on the side of the fixed frame and the movement of the cylinder to buffer the compression of the first spring, effectively preventing the revolving door from bending and deforming due to impact. Furthermore, the extrusion plate is not fixed to the revolving door, so when the extrusion plate is deformed and damaged by impact, it can be replaced separately, resulting in better performance.

[0021] 4. This solution uses a hollow column to restrict the top of the revolving door from the motor box, effectively preventing the motor box from separating from the connecting column and causing a decrease in the stability of the top of the revolving door. The hollow column restricts the movement direction of the connecting column, making the connecting column move downward more stably.

[0022] 5. This solution uses the movement of the second pressure plate to squeeze the oil reservoir, causing the oil reservoir to move downwards along with the sponge block. This facilitates the downward movement of the sponge block, allowing it to reach the bearing balls and lubricate the bearing. This makes lubrication of the bearing more convenient and eliminates the need for manual disassembly for lubrication.

[0023] 6. In this solution, after the sponge block reaches the bearing and is squeezed, the lubricating oil inside the sponge block is squeezed into the bearing balls. After the oil reservoir returns to its original position under the action of the second spring, the lubricating oil inside the oil reservoir cavity reaches the interior of the sponge block through the round hole for replenishment. This allows for multiple lubrications of the bearing, making lubrication more convenient. Attached Figure Description

Detailed Implementation

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

[0027] Example 1: Please see Figures 1 to 6 and Figure 8The access control and security monitoring system includes a revolving door 2. An image recognition component 1 is located on the left side of the revolving door 2. A motor box 4 is fixedly connected to the top left side of the revolving door 2. A side plate 21 is fixedly connected to the top left side of the revolving door 2. A drive component 9 is slidably connected inside the side plate 21. A connecting column 8 is slidably connected to the left side of the drive component 9 inside the side plate 21. An installation cavity 22 is formed inside the side plate 21. The connecting column 8 is used to connect to the motor box 4. The rotation of the motor box 4's output shaft drives the connecting column 8 to rotate, and the rotation of the connecting column 8 controls the rotation of the revolving door 2. The top of the connecting column 8... An extension forming a limiting block 85 extends into the interior of the motor box 4. A connecting rod 81 is fixedly connected to the bottom of the connecting column 8. A third spring 82 is welded to the bottom edge of the connecting column 8. A disc 83 is fixedly connected to the bottom of the connecting rod 81. A driving component 9 is used to drive the connecting column 8 to move, so that the connecting column 8 is disengaged from the motor box 4, and the rotation of the revolving door 2 is no longer restricted by the motor box 4. A first pressure plate 92 is fixedly connected to the bottom of the driving component 9. A second moving groove 23 is opened inside the side plate 21 corresponding to the displacement direction of the first pressure plate 92. The left side of the first pressure plate 92 is in contact with the top of the disc 83.

[0028] The front end of the revolving door 2 is provided with a protective mechanism 5. The protective mechanism 5 includes a fixing frame 51 fixed to the surface of the revolving door 2. A pressing plate 52 is slidably connected to the side of the fixing frame 51. The rear end of the pressing plate 52 extends into the interior of the side plate 21. A pressing groove 91 is formed on the top front side of the driving member 9. The cross-sectional shape of the pressing groove 91 is a right trapezoid. A slider 93 extends from the left side of the driving member 9. A third moving groove 24 is formed inside the side plate 21 to accommodate the movement of the slider 93. A first extension block 521 extends from the right side of the pressing plate 52. The interior of the fixing frame 51 corresponds to the first extension block 521. A through slot 511 is provided at the position of block 521. Multiple cylinders 53 are fixedly connected inside the extrusion plate 52. The cylinders 53 penetrate the side plate 21. A first spring 54 is welded to the surface of the cylinder 53. The bottom of both sides of the connecting column 8 extends to form a third extension block 84. The third extension block 84 is slidably connected to the inside of the side plate 21. A hollow column 6 is provided inside the side plate 21. The top of the hollow column 6 penetrates the side plate 21 and is fixedly connected to the motor box 4. A bearing 61 is movably connected between the bottom of the hollow column 6 and the side plate 21. The inner wall of the hollow column 6 is in contact with the outer surface of the connecting column 8 and the motor box 4.

[0029] When the device encounters a collision, since electric vehicles must pass through the access control, the collisions and scrapes mostly occur at the door opening. When the revolving door 2 is impacted at a position away from the image recognition component 1, it first impacts the surface of the extrusion plate 52. Upon impact, the extrusion plate 52 moves towards the revolving door 2. Since the extrusion plate 52 is fixedly connected to the cylinder 53, the movement of the extrusion plate 52 moves the cylinder 53 towards the revolving door 2, causing the cylinder 53 to pass through the side plate 21 while simultaneously compressing the first spring 54. The movement of the extrusion plate 52 on the side of the fixing frame 51 and the movement of the cylinder 53 compress the first spring 54. The compression provides cushioning, effectively preventing the revolving door 2 from bending and deforming due to impact. Since the compression plate 52 is not fixed to the revolving door 2, it can be replaced separately if damaged by impact, resulting in better performance. During the movement of the compression plate 52, it moves inside the side plate 21 along with the first spring 54. The first spring 54 moves the compression groove 91, causing it to be compressed and move downwards along with the driving member 9. The downward movement of the driving member 9 then moves the first pressure plate 92 downwards. One side of the first pressure plate 92 is above the disc 83, and the first... A pressure plate 92 contacts the upper surface of the disc 83. When the first pressure plate 92 moves downward, it moves the disc 83 downward as well. The disc 83 is connected to the connecting rod 81, and the connecting rod 81 is connected to the connecting column 8. The movement of the disc 83 moves the connecting column 8 downward, and the limiting block 85 at the top of the connecting column 8 leaves the inside of the motor box 4. The movement of the driving component 9 can be achieved through impact, making the movement of the driving component 9 more convenient. The impact also causes the connecting column 8 to disengage from the motor box 4. When the motor box 4 rotates, it will not rotate the connecting column 8, and thus will not rotate the revolving door 2. When the revolving door 2 encounters an impact, it will not lead to... The impact causes the connecting column 8 to rotate, which in turn causes the output shaft of the motor box 4 to rotate, resulting in damage to the motor. However, the rotation of the rotating door 2 is not affected by the motor box 4 or the connecting column 8. After being impacted, the rotating door 2 rotates on its own through the rotational connection between the rotating door 2 and the device frame, which can further reduce the impact force. The top of the rotating door 2 is restricted from the motor box 4 by the hollow column 6, which effectively prevents the motor box 4 from separating from the connecting column 8 and causing the top of the rotating door 2 to become unstable. The hollow column 6 restricts the movement direction of the connecting column 8, making the connecting column 8 move downward more stably.

[0030] like Figures 2 to 4 and Figures 6 to 7As shown, an oil storage box 7 is slidably connected to the inner surface of the hollow column 6 inside the side plate 21. A second spring 72 is welded to the bottom of the oil storage box 7. The second spring 72 is in a naturally extended state. A sponge block 73 is fixedly connected to the bottom of the oil storage box 7. The cross-sectional shape of the sponge block 73 is circular. The sponge block 73 is directly above the ball bearing 61. An oil storage cavity 74 for accommodating lubricating oil is opened inside the oil storage box 7. A plurality of circular holes 75 arranged in a circular array are opened at the bottom of the inner cavity of the oil storage box 7. The plurality of circular holes 75 are directly above the sponge block 73. The left side of the driving member 9 extends to form a second pressure plate 94. The left side of the second pressure plate 94 is above the oil storage box 7. The side of the oil storage box 7 extends to form a second extension block 71. A first moving groove 211 is opened inside the revolving door 2 corresponding to the position of the second extension block 71.

[0031] As the driving component 9 moves downward, it also moves the second pressure plate 94. The movement of the second pressure plate 94 squeezes the oil reservoir 7, causing the oil reservoir 7 to move and move the sponge block 73 downward, facilitating the movement of the sponge block 73 to the ball bearing 61. This allows the sponge block 73 to lubricate the bearing 61, making lubrication more convenient and eliminating the need for manual disassembly. The oil reservoir 7 has an oil storage chamber 74 and a round hole 75 inside. By injecting lubricating oil into the oil reservoir 7, the lubricating oil can reach the inside of the sponge block 73 through the round hole 75, allowing for the storage of lubricating oil. When the sponge block 73 reaches the bearing 61 and is squeezed, the lubricating oil in the sponge block 73 is squeezed into the ball bearing 61. After the oil reservoir 7 returns to its original position under the action of the second spring 72, the lubricating oil in the oil storage chamber 74 can reach the inside of the sponge block 73 through the round hole 75 for replenishment. This allows for multiple lubrications of the bearing 61, making lubrication more convenient.

[0032] Usage: When the revolving door 2 impacts a position away from the image recognition component 1, it first impacts the surface of the extrusion plate 52. Upon impact, the extrusion plate 52 moves towards the revolving door 2. The cylinder 53 passes through the side plate 21 while simultaneously extruding the first spring 54. During the movement of the extrusion plate 52, the extrusion plate 52 moves inside the side plate 21 along with the first spring 54. The rear end of the extrusion plate 52 moves to extrude the extrusion groove 91, driving the drive component 9 to move downward. The drive component 9 moves downward, causing the first pressure plate 92 to move downward, extruding the disc 83 along with the connecting column 8. The connecting column 8 disengages from the motor box 4. The drive component 9 moves downward while simultaneously moving the second pressure plate 94. The second pressure plate 94 extrudes the oil storage box 7, causing the oil storage box 7 to move and causing the sponge block 73 to move downward, reaching the ball bearing 61. The sponge block 73 lubricates the bearing 61. The lubricating oil inside the oil storage cavity 74 reaches the interior of the sponge block 73 through the round hole 75 for replenishment.
