Description

Technical Field

[0001] This solution belongs to the field of access control devices, specifically involving an Internet of Things (IoT) security monitoring room door access control device. Background Technology

[0002] With the popularization of Internet of Things (IoT) technology, modern access control systems integrate a large number of electronic components such as identity recognition, electric locks, communication modules, and alarm sensors. Their functions are becoming increasingly complex, and their operational reliability and stability are directly related to the effectiveness of the entire security system.

[0003] A search revealed a utility model patent with authorization announcement number CN216249374U, which discloses an IoT security smart cell door access control device, comprising: a device body and a top cover. A slide rail is fixedly connected to one side of the device body, a sliding strip is slidably connected to the inner wall of the slide rail, a liquid storage box is fixedly connected to one side of the sliding strip, a connecting rod is rotatably connected to the inner wall of the top cover, a dirt removal pad is fixedly connected to one side of the sliding strip, and an installation plate is provided on one side of the device body.

[0004] Based on the aforementioned patent searches and an examination of existing access control devices, it was found that sweat or moisture from operators' fingers can remain on the touchscreen control panel, affecting touch sensitivity and potentially causing misoperations. Furthermore, as critical equipment, access controllers require regular maintenance, upgrades, or emergency replacement. Currently, most controllers are directly fixed to the wall or mounting plate using multiple bolts or specialized tools via a mounting bracket on their back. In confined spaces or scenarios requiring rapid emergency response, tightening or loosening these bolts is extremely inconvenient, time-consuming, and labor-intensive, severely impacting maintenance efficiency. Utility Model Content

[0005] The purpose of this solution is to provide an IoT-based security monitoring room access control device to solve the problem of existing access control devices being easily misoperated due to sweaty fingers, while also addressing the inconvenience of disassembly and maintenance.

[0006] To achieve the above objectives, this solution provides an IoT security monitoring room access control device, including an access controller housing. The front of the housing has a control panel and a touch panel. A U-shaped tube is fixedly connected to the top of the housing, penetrating the entire housing. A horizontal tube is connected to the outer end of the U-shaped tube, with a slot at its bottom. A shroud is connected to the inner end of the U-shaped tube, and a fan is installed inside the shroud to draw air. Air circulates rapidly on the front of the access control controller housing, entering the horizontal tube through the slot and then exiting through the collector shroud, thus dissipating heat from the electronic components inside the housing. The heat is finally expelled through the ventilation holes. This prevents sweaty fingers from affecting the operation of the control panel and touch panel. Multiple ventilation holes are located on the bottom of the access control controller housing. A mounting base is fixedly connected to the back of the housing, with side plates contacting both sides. A mounting plate is fixedly connected between the two side plates, located on the back of the mounting base. Through bolt holes are provided at each of the four corners of the mounting plate.

[0007] The principle of this solution is as follows: During use, the mounting plate with two side plates is securely installed on the predetermined wall position next to the cell door using expansion bolts or other fasteners through the bolt holes at its four corners. The mounting base on the back of the access controller housing is aligned with the mounting plate, and then pushed horizontally towards the mounting plate. At this point, the side plates on both sides of the mounting plate will fit against the mounting base and the sides. Furthermore, before insertion, the square rod needs to be pressed down by pressing the plate, which in turn moves the linkage plate. When the linkage plate moves down, the arc-shaped part of its bottom arc rod descends accordingly and moves along the moving... The inclined groove of the block slides, generating an inward horizontal component force, which overcomes the reaction force of spring one and pushes the two moving blocks and the pin to retract synchronously towards the center of the mounting base. After the mounting base is placed in place, the pressing plate is released. Under the action of the restoring force of spring two and the attraction force of the magnetic column, the square rod and the linkage plate rise back to the initial position. The pin extends again under the action of spring one, so that the pin is inserted into the insertion hole of the side plate, thus completing the overall installation. Later, only one operation of pressing the square rod is needed to disassemble the access controller shell for maintenance. Users can operate the access control controller via the control panel and touch panel on the front of the casing. During use, the fan starts and generates suction, drawing air out of the casing through the manifold, creating negative pressure inside. This pressure forces external air to flow, guiding it across the front of the casing, particularly the control panel area, forming an air curtain. This airflow disperses any sweat or moisture left by the user, keeping the panel dry and clean. Additionally, the airflow is drawn in through the slot at the bottom of the horizontal tube, flows through the horizontal tube and U-shaped tube, and enters the interior of the casing. The cooling air inside absorbs heat generated by the electronic components, becoming hot air, which is then exhausted through the ventilation holes at the bottom of the casing.

[0008] The technical advantages of this solution are as follows: through the synergistic effect of the U-shaped tube, horizontal tube, and fan, air can be guided to flow rapidly from the front to the interior when the user operates the control panel and button touch panel, forming a directional airflow. This design not only effectively removes the heat generated by the electronic components inside the access controller housing, improving heat dissipation efficiency and avoiding equipment failure or shortened lifespan due to overheating, but also promptly blows away any sweat or moisture that may remain during user operation, reducing operational errors or panel contamination caused by hand sweat. It balances heat dissipation performance and operational reliability, and is especially suitable for security scenarios with high humidity or high frequency of use.

[0009] The mounting base uses a pin-and-side-plate connection for fixation. Combined with the transmission structure of square rod, linkage plate, arc rod and inclined groove, it enables quick disassembly and assembly of the access controller housing. Users only need to press down the square rod to retract the pin through the inclined drive, detaching it from the side plate and completing the disassembly. After release, spring one and spring two work together to reset, ensuring a stable installation. This design eliminates the tedious steps of traditional bolt disassembly and improves maintenance efficiency.

[0010] Furthermore, a deflector plate is fixedly connected to the bottom of the access control controller housing, and the position of the deflector plate corresponds to the position of the heat dissipation holes. The deflector plate is inclined downwards, and the inclined direction is towards the back of the access control controller housing, so that the emitted heat is not easily returned to the front of the access control controller housing.

[0011] Furthermore, a support plate is fixedly connected to the inner wall of the mounting base. A slider is slidably connected to the upper edge of the support plate. A moving block is fixedly connected to the top of the slider. The moving block has an inclined groove inside, which penetrates the moving block. A pin is fixedly connected to the end of the moving block, penetrating the mounting base and slidably connected to it. The pin also penetrates the side plate and is inserted into it. A square rod is slidably connected to the top of the mounting base, penetrating it. A linkage plate is fixedly connected to the lower end of the square rod. An arc rod is fixedly connected to the bottom edge of the linkage plate, and the lower arc portion of the arc rod is slidably connected to the inclined surface of the inclined groove. By pressing down the square rod, the square rod drives the linkage plate and its bottom arc rod to move down synchronously. The arc end of the arc rod cooperates with the inclined groove of the moving block, which can control the lateral extension and retraction of the moving block, thereby controlling the engagement and disengagement of the pin and the side plate, thus facilitating the disassembly and assembly of the access controller housing.

[0012] Furthermore, a spring is also fixedly connected between the slider and the inner wall of the mounting base. The elastic force of the spring can act on the moving block and the pin through the slider.

[0013] Furthermore, a pressing plate is fixedly connected to the top of the square rod, and the pressing plate and the square rod are an integral structure. The pressing plate can increase the contact area between the square rod and the user's fingers.

[0014] Furthermore, a second spring is sleeved on the outer side of the square rod. One end of the second spring is fixedly connected to the linkage plate, and the other end is fixedly connected to the inner top of the mounting base. The reaction force of the second spring can act on the linkage plate, providing auxiliary resetting.

[0015] Furthermore, a magnetic post is fixedly connected to the top inner side of the mounting base, and the lower end of the magnetic post is attracted to the linkage plate. The magnetic post provides auxiliary fixation for the linkage plate, preventing it from being affected by vibration. Attached Figure Description

[0018] The basic implementation examples are as follows: Figures 1-7 As shown: An IoT security monitoring room access control device includes an access controller housing 1. The front of the access controller housing 1 is provided with a control panel 101 and a button touch panel 102. A U-shaped tube 2 is fixedly connected to the top of the access controller housing 1, and the U-shaped tube 2 penetrates through the access controller housing 1. A horizontal tube 3 is connected to the end of the U-shaped tube 2 outside the access controller housing 1. A strip-shaped opening 301 is opened at the bottom of the horizontal tube 3. A flow collector 4 is connected to the end of the U-shaped tube 2 inside the access controller housing 1. A fan is installed inside the flow collector 4. Fan 5 draws air from the front of the access control controller housing 1, allowing for rapid airflow. The air enters the horizontal pipe 3 through the strip-shaped opening 301 and is then discharged through the collector shroud 4, thus dissipating heat from the electronic components inside the access control controller housing 1. The heat is finally expelled through the heat dissipation holes 6. This prevents the operation of the control panel 101 and the touch panel 102 from being affected by the user's sweaty fingers. Multiple heat dissipation holes 6 are provided at the bottom of the access control controller housing 1, and a guide plate 7 is fixedly connected to the bottom of the access control controller housing 1. The position of the guide plate 7 corresponds to the position of the heat dissipation holes 6. The guide plate 7 is tilted downwards, with the tilt direction facing the back of the access control controller housing 1, so that the dissipated heat is less likely to return to the front of the access control controller housing 1.

[0019] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 7As shown, a mounting base 8 is fixedly connected to the back of the access control controller housing 1. Side plates 9 are in contact with both sides of the mounting base 8. A mounting plate 91 is fixedly connected between the two side plates 9, and the mounting plate 91 is located on the back of the mounting base 8. Through bolt holes are provided at all four corners of the mounting plate 91. A support plate 10 is fixedly connected to the inner wall of the mounting base 8. A slider 11 is slidably connected to the upper edge of the support plate 10. A moving block 12 is fixedly connected to the top of the slider 11. An inclined groove is provided inside the moving block 12, and the inclined groove passes through the moving block 12. A pin 13 is fixedly connected to the end of the moving block 12. The pin 13 passes through the mounting base 8 and is slidably connected to the mounting base 8. The pin 13 also passes through the side plates 9 and is inserted into the side plates 9. A spring 14 is also fixedly connected between the slider 11 and the inner wall of the mounting base 8. The elastic force of spring 14 can act on moving block 12 and pin 13 through slider 11. A square rod 15 is slidably connected to the top of mounting base 8, and the square rod 15 is set through mounting base 8. A pressing plate 16 is fixedly connected to the top of square rod 15, and the pressing plate 16 and square rod 15 are integral structures. The pressing plate 16 can increase the contact area between square rod 15 and user's fingers. A linkage plate 17 is fixedly connected to the lower end of square rod 15. An arc rod 18 is fixedly connected to the bottom edge of linkage plate 17. The lower arc part of arc rod 18 is slidably connected to the inclined part of inclined groove. Spring 2 19 is sleeved on the outside of square rod 15. One end of spring 2 19 is fixedly connected to linkage plate 17, and the other end of spring 2 19 is fixedly connected to the inner top of mounting base 8. The reaction force of spring 2 19 can act on linkage plate 17, which has an auxiliary resetting function. A magnetic post 20 is fixedly connected to the top inner side of the mounting base 8, and the lower end of the magnetic post 20 is attracted to the linkage plate 17. The magnetic post 20 provides auxiliary fixation for the linkage plate 17, preventing it from being affected by vibration. By pressing down the square rod 15, the square rod 15 drives the linkage plate 17 and its bottom arc rod 18 to move down synchronously. The arc end of the arc rod 18 cooperates with the inclined groove of the moving block 12, which can control the lateral extension and retraction of the moving block 12, thereby controlling the engagement and disengagement of the latch 13 and the side plate 9, so as to facilitate the disassembly and assembly of the access control controller housing 1.

[0020] The specific implementation process of this utility model is as follows: In use, the mounting plate 91 with two side plates 9 is firmly installed on the predetermined wall position next to the cell door through the bolt holes at its four corners using expansion bolts or other fasteners. The mounting base 8 on the back of the access control controller housing 1 is aligned with the mounting plate 91 and pushed horizontally towards the mounting plate 91. At this time, the side plates 9 on both sides of the mounting plate 91 will fit against the mounting base 8 and the sides. In addition, before insertion, the square rod 15 needs to be pressed down by the pressing plate 16, thereby driving the linkage plate 17 to move. When the linkage plate 17 moves down, the arc part of the arc rod 18 at its bottom descends accordingly and moves along the moving block. The inclined groove of 12 slides, generating an inward horizontal component force, and overcoming the reaction force of spring 14, pushing the two moving blocks 12 and the pin 13 to retract synchronously towards the center of the mounting base 8. After the mounting base 8 is placed in place, the pressing plate 16 is released. Under the action of the restoring force of spring 29 and the attraction force of magnetic column 20, the square rod 15 and the linkage plate 17 rise back to the initial position. The pin 13 extends again under the action of spring 14, so that the pin 13 is inserted into the socket of the side plate 9, thereby completing the overall installation. Later, only one operation of pressing the square rod 15 is needed to disassemble the access controller housing 1 for maintenance. Users can operate the access control controller housing 1 on the control panel 101 and the button touch panel 102 on the front. During use, the fan 5 is started, and the fan 5 generates suction to draw the air inside the access control controller housing 1 through the collector shroud 4, creating a negative pressure inside. This pressure drives the external air to flow, and the external air is guided to flow from the front of the access control controller housing 1, especially the panel operation area, forming an air curtain. This airflow blows away any sweat or moisture that may be left by the user during operation, keeping the panel dry and clean. On the other hand, the airflow is drawn in through the strip-shaped opening 301 at the bottom of the horizontal tube 3, flows through the horizontal tube 3 and the U-shaped tube 2, and enters the interior of the access control controller housing 1. The cooling air inside absorbs the heat generated by the electronic components and becomes hot air, which is then discharged through the heat dissipation hole 6 at the bottom of the access control controller housing 1.

[0021] This solution, through the coordinated action of the U-shaped tube 2, the horizontal tube, and the fan 5, guides air to flow rapidly from the front to the interior when the user operates the control panel 101 and the button touch panel 102, forming a directional airflow. This design not only effectively removes the heat generated by the electronic components inside the access controller housing 1, improving heat dissipation efficiency and preventing equipment failure or shortened lifespan due to overheating, but also promptly disperses any sweat or moisture that may remain during user operation, reducing operational errors or panel contamination caused by hand sweat. It balances heat dissipation performance and ease of use. For reliable operation, it is especially suitable for security scenarios with high humidity or high frequency of use. The mounting base 8 adopts a fixing method of plugging the pin 13 into the side plate 9. Combined with the transmission structure of the square rod 15, linkage plate 17, arc rod 18 and inclined groove, it realizes the quick disassembly and assembly of the access controller shell 1. The user only needs to press down the square rod 15 to drive the pin 13 to retract through the inclined groove, disengage from the side plate 9, and complete the disassembly. After release, the spring 14 and the spring 2 19 work together to reset, ensuring a stable installation. This design eliminates the tedious steps of traditional bolt disassembly and improves maintenance efficiency.

[0022] The above descriptions are merely embodiments of this utility model, and common knowledge regarding specific structures and characteristics is not elaborated upon here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this utility model, and these should also be considered within the scope of protection of this utility model.
