Technical Field

[0001] The utility model relates to the technical field of security, in particular to a door access security device. Background Art

[0002] Face recognition is a biometric technology that identifies people based on their facial features. It uses a camera or camcorder to collect images or video streams containing faces, and automatically detects and tracks faces in the images, and then performs a series of face-related technologies on the detected faces. Because face recognition has the function of identity authentication, face recognition technology is often used in various types of security access control devices. Through face recognition, people with legitimate identities are allowed to enter, and people with illegal identities are prevented from entering, thereby achieving the effect and purpose of security.

[0003] The existing access control security device refers to the patent document CN218384057U. When the device proposed in the patent document performs face recognition, a person stands under the sunshade and adjusts the angle of the sunshade relative to the face recognition device to achieve a better shading effect, thereby increasing the efficiency of the face recognition device for face recognition under strong light and avoiding people standing in the sun for a long time.

[0004] However, in actual use, it was found that since the face recognition device is completely exposed to the air and does not provide certain protection for the device, long-term wind and sun exposure will affect the clarity of the screen, and accidental bumps by users may also cause damage to the screen, which is not conducive to the work of face recognition. For this reason, we provide a access control security device to solve the above problems. Utility Model Content

[0023] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0024] As described in the background art, in order to solve the problem that the device has no protective facilities, this embodiment provides an access control security device, which is provided with a replaceable transparent protective cover, which effectively provides protection for the device and prolongs the service life of the device.

[0025] See also Figures 1 to 5 This embodiment proposes an access control security device, including an access control security device body 1, a display screen 2 and a camera 3, wherein the display screen 2 and the camera 3 are both installed on the front side of the access control security device body 1.

[0026] The camera 3 is located above the display screen 2, and the camera 3 and the display screen 2 are electrically connected to the chip inside the access control security device body 1. The chip inside the access control security device body 1 is not the object of protection in this application, so the working principle and internal structure of the chip will not be described in detail.

[0027] The display screen 2 and the camera 3 are both existing devices, and the outer surfaces of the display screen 2 and the camera 3 are glass panels. After being exposed to the outside for a long time, the glass panels on the outer surfaces of the display screen 2 and the camera 3 are prone to scratches or damage, which is not only not conducive to the face recognition work of the camera 3, but also requires a lot of time to replace the glass panels on the surface of the display screen 2 and the camera 3.

[0028] Preferably, the camera 3 can adopt an infrared and color light dual camera to make the facial features captured by it clearer. By setting the camera 3, the face can be detected and recognized, and by setting the display screen 2, the collected facial features can be displayed.

[0029] A circuit assembly 4 is installed on the bottom surface of the access control security device body 1 , one end of the circuit assembly 4 is electrically connected to a chip inside the access control security device body 1 , and evenly distributed heat dissipation openings 5 ​​are provided on the bottom surface of the access control security device body 1 .

[0030] By providing the circuit assembly 4, the device can be connected to an external circuit for power supply and data transmission. By providing the heat dissipation vent 5, air exchange inside and outside the access control security device body 1 can be ensured.

[0031] Mounting blocks 7 are installed at the four corners of the back of the access control and security device body 1 , and four evenly distributed external connection ports 8 are opened on the back of the access control and security device body 1 .

[0032] By providing the mounting block 7 and the external port 8 , the access control security device body 1 can be installed in different ways. The staff can install the device by connecting an external bracket or other equipment through the external port 8 , or directly install the device at a designated location through the mounting block 7 .

[0033] The exterior of the access control security device body 1 is provided with a protection mechanism 6, which includes a special-shaped groove 601 and a first limiting hole 606 provided on both sides of the exterior surface of the access control security device body 1. The shape of the special-shaped groove 601 is as follows: Figure 1 shown.

[0034] Two L-shaped plates 602 are fixedly connected to the outer surface of the access control security device body 1 . The inner wall of each L-shaped plate 602 is slidably sleeved with a limitable blocking rod 603 . The outer surface of each blocking rod 603 is fixedly connected to a disc 604 .

[0035] The outer surface of each disc 604 is fixedly connected to a handle 610 , and the outer surface of each handle 610 is coated with an anti-slip layer. By providing the handle 610 , the contact area of ​​the disc 604 can be increased, making it easier to pull the disc 604 .

[0036] The outer surface of each disc 604 is fixedly connected with a telescopic spring 605 . The ends of the two telescopic springs 605 that are close to each other are fixedly connected to the side surfaces of the two L-shaped plates 602 that are away from each other. The two telescopic springs 605 are respectively sleeved on the outside of the two blocking rods 603 .

[0037] By limiting the positional relationship of the telescopic spring 605, the state of the blocking rod 603 can be conveniently limited. When the round piece 604 is pulled, the blocking rod 603 can be moved out from the corresponding first limiting hole 606, and the corresponding telescopic spring 605 can be in a stretched state. When the telescopic spring 605 is deformed, elastic force will be generated.

[0038] A transparent protective cover 607 is provided on the outside of the access control security device body 1. The material of the transparent protective cover 607 is transparent and will not affect the display screen 2 and the camera 3 to recognize the face.

[0039] Second limiting holes 608 are provided on both sides of the outer surface of the transparent protective cover 607 . Two special-shaped sliders 609 are fixedly connected to the inner wall of the transparent protective cover 607 . The transparent protective cover 607 is slidably sleeved in the two special-shaped grooves 601 through the two special-shaped sliders 609 .

[0040] The position and size relationship between the blocking rod 603, the first limiting hole 606 and the second limiting hole 608 are kept consistent. By limiting the relationship between the blocking rod 603, the first limiting hole 606 and the second limiting hole 608, the blocking rod 603 can limit the transparent protective cover 607 through the first limiting hole 606 and the second limiting hole 608, thereby ensuring the stability of the installation of the transparent protective cover 607.

[0041] By setting up a transparent protective cover 607, a certain degree of protection can be provided for the access control security device body 1, the display screen 2 and the camera 3, so that the access control security device body 1, the display screen 2 and the camera 3 can perform face recognition without being directly and completely exposed to the air, effectively reducing the probability of damage to the surface glass panels of the display screen 2 and the camera 3, and extending the service life of the device.

[0042] At the same time, the transparent protective cover 607 can be conveniently installed and removed on the outer surface of the access control security device body 1, which is convenient for replacing the worn or damaged transparent protective cover 607, thereby improving the practicality of the device.

[0043] Working principle: when in use, the special-shaped sliders 609 on both sides of the transparent protective cover 607 are respectively inserted along the two special-shaped grooves 601, and then the two handles 610 are pulled outward to make the two blocking rods 603 move out of the corresponding first limiting holes 606 respectively without blocking the transparent protective cover 607. When the special-shaped sliders 609 on both sides of the transparent protective cover 607 are fully inserted into the corresponding special-shaped grooves 601, the blocking rod 603, the first limiting hole 606 and the second limiting hole 608 will be on the same horizontal line. In this way, the two pulled handles 610 are released to make the transparent protective cover 607 located in front of the display screen 2 and the camera 3. In this way, the two blocking rods 603 will be reset respectively by the elastic force generated by the deformation of the corresponding telescopic springs 605, and the blocking rod 603 will pass through the second limiting hole 608 and be inserted into the first limiting hole 606 to realize the limited installation of the transparent protective cover 607. At this time, the display screen 2 and the camera 3 are Located inside the transparent protective cover 607, the transparent protective cover 607 can provide protection for the glass panels on the surface of the display screen 2 and the camera 3, reduce the probability of damage to the glass panels on the surface of the display screen 2 and the camera 3, ensure the face recognition effect of the camera 3, and through face recognition, allow people with legal identities to enter, and prevent people with illegal identities from mixing in, thereby achieving the effect and purpose of security. When the surface of the transparent protective cover 607 is worn or damaged, the two handles 610 can be pulled outward to make the two blocking rods 603 move out from the inner walls of the first limiting hole 606 and the second limiting hole 608 in turn, so that the limit on the transparent protective cover 607 is released, and the staff can directly pull the transparent protective cover 607 upward for disassembly, and then take out the new transparent protective cover 607 and repeat the above steps to install it. No additional tools are required in the whole process, making the replacement of the transparent protective cover 607 more convenient.
