Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0022] Embodiment one

[0023] As shown in Figure 1 , Figure 2 , Figure 3 and Figure 4 , the utility model provides an embodiment: a kind of adjustable face identification machine, including shell 3, identification machine body 1 is movably installed in shell 3, wide-angle adjusting assembly 4 is fixedly installed in shell 3, and wide-angle adjusting assembly 4 includes mounting frame 42, convex lens 41 is embeddedly installed in mounting frame 42, convex lens 41 is located at the front of identification machine body 1, first sliding frame 43 is fixedly installed at the top of mounting frame 42, second sliding frame 45 is fixedly installed at the bottom of mounting frame 42, and the rear end of first sliding frame 43 and the rear end of second sliding frame 45 are fixedly connected with the rear end of inside of shell 3 respectively through connecting frame 44.

[0024] Identification machine body 1 back is fixedly installed with air cylinder 5 by connecting plate 51, and the rear end of air cylinder 5 passes through the rear end of shell 3 and is fixedly connected with shell 3, and air cylinder 5 is parallel with first sliding frame 43 and second sliding frame 45.

[0025] Specifically, the recognition device body 1 is movably installed within the housing 3, meaning it is not fixed in one position but can be moved as needed. A wide-angle adjustment assembly 4 is fixedly installed within the housing 3. This assembly includes a mounting bracket 42, within which a convex lens 41 is embedded. The convex lens 41 is located on the front of the recognition device body 1, helping to adjust the shooting angle for a clearer facial image. A first slide 43 and a second slide 45 are fixedly installed at the top and bottom of the mounting bracket 42, respectively. The slide design allows the convex lens 41 to move back and forth within a certain range. A cylinder 5 is fixedly installed on the back of the recognition device body 1 via a connecting plate 51. The rear end of the cylinder 5 passes through the rear end of the housing 3 and is fixedly connected to it. When the cylinder 5 is activated, it can push the recognition device body 1 to translate within the housing 3. Through the pushing of the cylinder 5, the recognition device body 1 can translate back and forth within the housing 3, thereby adjusting the distance between the recognition device body 1 and the convex lens 41. This adjustment allows the device to change the shooting distance based on the user's standing position to obtain a clearer facial image. When the user is standing far away, adjusting cylinder 5 allows the recognition unit 1 to move closer to or further away from the convex lens 41 to obtain the optimal facial image. This adjustment helps improve the accuracy of face recognition, especially at long distances. Through the above design, this adjustable face recognition device can adapt to different user standing positions, improving the accuracy and reliability of face recognition by adjusting the shooting distance and angle.

[0026] Example 2

[0027] In order to effectively protect the built-in identification device, such as Figure 1 and Figure 2 As shown, in this embodiment, the front end of the housing 3 adopts an open structure design and is fixedly installed with a cover 2. The upper surface of the housing 3 has a rectangular array of heat dissipation holes 31, and the bottom of the back of the housing 3 has a cable hole 32. The open design of the front end of the housing 3, equipped with a cover 2, not only provides an easily accessible maintenance and cleaning channel, but also enhances the aesthetics of the device. The rectangular array of heat dissipation holes 31 on the upper surface of the housing 3 effectively improves the heat dissipation efficiency of the device and ensures the stability of the face recognition machine during long-term operation. The cable hole 32 at the bottom of the back of the housing 3 makes the wiring of the power cord and data cable neater and easier to hide, improving the overall aesthetics of the device.

[0028] Furthermore, the cover 2 is fixedly connected to the housing 3 by mounting screws, and a transparent tempered glass is embedded inside the cover 2. The design of fixing the cover 2 to the housing 3 with mounting screws ensures the stability and security of the cover 2. The embedded transparent tempered glass not only protects the camera from dust and impact damage but also provides a clear visual effect.

[0029] Furthermore, a camera is located in the center of the front of the recognition machine body 1, and LED supplementary lights are embedded on both sides of the front of the recognition machine body 1. Sleeves are fixedly installed on both sides of the upper end face of the recognition machine body 1. In this design, the camera is located in the center of the front of the recognition machine body 1, and LED supplementary lights are embedded on both sides. This layout ensures that clear facial images can be obtained under various lighting conditions. The sleeves fixedly installed on both sides of the upper end face of the recognition machine body 1 provide stable support for the carriage.

[0030] Example 3

[0031] In order to effectively adjust the distance between the recognition device body and the convex lens, such as Figure 3 and Figure 4 As shown, in this embodiment, the convex lens 41 is located directly in front of the camera on the recognition machine body 1, and the front of the convex lens 41 does not contact the tempered glass inside the cover 2. The design of the convex lens 41 being located directly in front of the camera on the recognition machine body 1 helps to concentrate light and improve image clarity. The fact that the front of the convex lens 41 does not contact the tempered glass inside the cover 2 avoids scratches or damage caused by contact.

[0032] Furthermore, both the first slide 43 and the second slide 45 adopt a U-shaped structure design. The first slide 43 passes through the sleeve at the top of the identification machine body 1, and the second slide 45 is located below the identification machine body 1 and does not contact it. The U-shaped structure design of both the first slide 43 and the second slide 45 provides greater adjustment space and stability. The layout ensures the flexibility and stability of the equipment.

[0033] Furthermore, the connecting frame 44 is fixedly connected to the inner rear end of the housing 3 by mounting screws. A nut post 441 is welded and installed in the middle of the side of the connecting frame 44 away from the housing 3. The rear ends of the first slide 43 and the second slide 45 are respectively threaded to the nut post 441. In this design, the connecting frame 44 is fixedly connected to the inner rear end of the housing 3 by mounting screws, which ensures the stability of the connecting frame 44. The nut post 441 is welded and installed in the middle of the side of the connecting frame 44 away from the housing 3, and the rear ends of the first slide 43 and the second slide 45 are respectively threaded to the nut post 441. This design provides precise adjustment capability.

[0034] When using this invention, place the face recognition machine in a suitable position, ensuring the housing 3 is stably installed. Pass the power cord and connecting wires through the wiring hole 32 at the bottom back of the housing 3 and connect them to the power source and network. Ensure the cover 2 is correctly installed at the front end of the housing 3. A transparent tempered glass is embedded inside the cover 2 to protect the camera from dust and impact damage. Turn on the power and start the face recognition machine. Adjust the LED supplementary lights on both sides of the front of the recognition machine body 1 according to the ambient light conditions to ensure clear facial images are obtained under various lighting conditions. During face recognition, the person stands in front of the face recognition machine and waits for the camera to capture the facial image. When the person is standing far away, the cylinder 5 pushes the recognition machine body 1 to move horizontally within the housing 3, changing the distance between the recognition machine body 1 and the convex lens 41 to obtain the best facial image. If the recognition result is not ideal, the cylinder 5 can be readjusted to optimize the shooting angle and distance until a satisfactory recognition effect is obtained. After use, the camera and tempered glass should be cleaned regularly to maintain the optimal performance of the device.
