[0001] This utility model relates to the field of facial recognition terminal technology, specifically a protective facial recognition terminal. Background Technology

[0002] A facial recognition terminal is an identity verification device that combines advanced technology with convenience. It uses a camera or webcam to capture facial images or video streams, automatically detects and tracks faces, and uses advanced algorithms to process and analyze the images to accurately identify each person's facial features, thereby achieving identity verification and access control. This device features automatic facial recognition, high-precision recognition, multi-scenario application, and integration of multiple functions. It is not limited to access control systems but is also widely used in public places for access management, attendance tracking, security monitoring, and other fields.

[0003] A search revealed Chinese patent publication number CN220020333U, which discloses a secure facial recognition fingerprint scanner. The scanner mechanism includes a protective cover, with the scanner body installed inside the cavity of the cover. A winding shaft is mounted on the top of the cavity, and both ends of the winding shaft have springs. A traction curtain is wound around the winding end of the shaft, extending through to the opening of the protective cover. This invention utilizes a self-protective scanner mechanism. When not in use, the winding curtain provides protective coverage for the scanner body. This prevents dust from adhering to the scanner and affecting normal operation, and also isolates it from external sewage and moisture, preventing a reduction in the scanner's lifespan.

[0004] The aforementioned patent has the following shortcomings: Since the device needs to fix the screen with hooks and rings and use a spring to automatically retract the screen, when the user uses the device, the spring retracts the screen and simultaneously moves the hooks upwards quickly, which can easily cause the hooks to scratch the user's hands, causing injury and affecting the user experience. In addition, when the screen covers the device, there are gaps on the sides and bottom, which affects the screen's blocking effect. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a protective face recognition terminal to solve the technical problems of hooks easily scratching users' hands and poor screen blocking effect.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a protective face recognition terminal, comprising a main body and a functional mechanism, wherein the functional mechanism includes a snap-fit ​​block and a first sliding groove, both ends of the snap-fit ​​block are provided with protrusions, the top of the first sliding groove is provided with a limit block, a slider is snapped and slidably moved in the first sliding groove, a snap-fit ​​groove is opened at the bottom of the first sliding groove, an installation groove is opened on one side of the snap-fit ​​groove, a spring snap-fit ​​block is provided inside the installation groove, a second sliding groove is opened on one side of the installation groove, and a push rod is snapped and slidably moved in the second sliding groove.

[0007] By adopting the above technical solution, the push rod can be used to manually push the spring latch, thereby releasing the latch block and facilitating the unfolding or retraction of the curtain.

[0008] Furthermore, two spring clips are symmetrically arranged along the central axis of the first slide groove, and the spring clips are wedge-shaped.

[0009] By adopting the above technical solution, the two spring clips are symmetrically arranged and can work together on the clip to provide fixing force from both sides at the same time, ensuring the stable fixation of the curtain in the rolling or unfolding state and preventing shaking or falling off due to force on one side.

[0010] Furthermore, the snap-fit ​​block is cylindrical in shape and is adapted to the snap-fit ​​groove.

[0011] By adopting the above technical solution, the cylindrical snap-fit ​​block has a smooth surface and a uniform diameter, which allows it to be inserted into the snap-fit ​​slot smoothly and unobstructed, and can also be easily removed when needed, thus improving the ease of operation.

[0012] Furthermore, an outer shell is provided on the outside of the main body, and springs are provided on both sides of the outer shell.

[0013] By adopting the above technical solution, the outer shell, as the external protective layer of the main body, can effectively prevent external dust, moisture, impact and other adverse factors from damaging the main body and its internal components, ensuring the normal operation of the equipment and extending its service life.

[0014] Furthermore, one end of the spring is provided with a spool, and the outer surface of the spool is provided with a curtain.

[0015] By adopting the above technical solution, the spring has energy storage characteristics. When the curtain is pulled open, the spring will store mechanical energy.

[0016] Furthermore, one end of the curtain is fixedly connected to the snap-fit ​​block and the slider, and the slider is made of rubber.

[0017] By adopting the above technical solution, this fixed connection ensures a tight connection between the curtain and the functional mechanism during the unfolding and retraction process, preventing the curtain from falling off or shaking, and ensuring the normal operation and use of the equipment.

[0018] Furthermore, a mounting plate is provided on the back of the housing.

[0019] By adopting the above technical solution, the mounting plate provides a solid installation foundation for the entire protective face recognition terminal.

[0020] In summary, the present invention has the following main advantages:

[0021] 1. This utility model, through the setting of a functional mechanism, allows the rubber slider to effectively increase the friction of the inner wall of the first slide groove when sliding within it, thereby reducing the movement speed of the curtain during retraction and increasing the safety of the equipment. At the same time, the smooth edge of the cylindrical locking block further enhances the safety of the curtain retraction. Meanwhile, the locking groove and spring locking block stably engage and fix the locking block, increasing the ease of use of the equipment. The push rod and the second slide groove enable the locking block to be quickly unlocked, further improving ease of use and enhancing the user experience. Attached Figure Description

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0028] A type of protective facial recognition terminal, such as Figures 1-4As shown, the device includes a main body 1 and a functional mechanism 6. The functional mechanism 6 includes a snap-fit ​​block 601 and a first slide groove 603. The snap-fit ​​block 601 has protrusions 602 at both ends. The top of the first slide groove 603 has a limiting block 604. A slider 605 is engaged and slids in the first slide groove 603. A snap-fit ​​groove 606 is opened at the bottom of the first slide groove 603. A mounting groove 607 is opened on one side of the snap-fit ​​groove 606. A spring snap-fit ​​block 608 is provided inside the mounting groove 607. A second slide groove 610 is opened on one side of the mounting groove 607. A push rod 609 is engaged and slids in the second slide groove 610. The push rod 609 can be used to manually push the spring snap-fit ​​block 608 to release the snap-fit ​​block 601, which facilitates the unfolding or retraction of the curtain. The limiting block 604 restricts the sliding range of the slider 605, preventing the slider 605 from coming out of the slide groove and ensuring the integrity of the structure.

[0029] See Figure 4 Two spring clips 608 are symmetrically arranged along the central axis of the first slide groove 603. The spring clips 608 are wedge-shaped. The two spring clips 608 are symmetrically arranged and can work together to provide fixing force from both sides to ensure the stable fixation of the curtain 5 in the rolling or unfolding state, and prevent shaking or falling off due to force on one side. When the wedge-shaped spring clips 608 are subjected to external force, they can generate a self-locking effect by using their inclined surface. That is, when the locking block 601 is inserted, the spring clips 608 will be squeezed and generate elastic force, thereby tightly locking the locking block 601 and preventing it from accidentally falling off.

[0030] See Figure 2 , Figure 3 The snap-fit ​​block 601 is cylindrical in shape and is adapted to the snap-fit ​​groove 606. The cylindrical snap-fit ​​block 601 has a smooth surface and a uniform diameter, which allows it to be inserted into the snap-fit ​​groove 606 smoothly and unobstructed, and can also be easily removed when needed, improving the convenience of operation. The shape and size of the snap-fit ​​block 601 and the snap-fit ​​groove 606 are perfectly matched, ensuring a tight connection between the two.

[0031] See Figure 1 , Figure 3 The outer shell 2 is provided on the outside of the main body 1, and the springs 3 are provided on both sides of the outer shell 2. The outer shell 2 serves as an external protective layer for the main body 1, which can effectively prevent external dust, moisture, impact and other adverse factors from damaging the main body 1 and its internal components, ensuring the normal operation of the equipment and extending its service life. The springs 3 are placed on both sides of the outer shell 2, which makes full use of the space structure of the equipment, making the equipment more compact and easy to install and arrange.

[0032] See Figure 2One end of the spring 3 is provided with a roller 4, and the outer surface of the roller 4 is provided with a curtain 5. The spring 3 has energy storage characteristics. When the curtain 5 is pulled and unfolded, the spring 3 will store mechanical energy. The outer surface of the roller 4 is flat and smooth, which can ensure that the curtain 5 is evenly distributed during the winding process, avoiding wrinkles or overlaps, and ensuring the flatness and aesthetics of the curtain 5.

[0033] See Figure 2 One end of the screen 5 is fixedly connected to the snap-fit ​​block 601 and the slider 605. The slider 605 is made of rubber. This fixed connection ensures that the screen 5 is tightly connected to the functional mechanism 6 during the unfolding and retraction process, preventing the screen from falling off or shaking, and ensuring the normal operation and use of the equipment. The rubber material has good elasticity and friction. When the slider 605 slides in the first slide groove 603, it can slow down the retraction speed of the screen 5 and prevent the screen from hitting the equipment or generating noise due to rapid retraction.

[0034] See Figure 1 The back of the outer casing 2 is provided with a mounting plate 7, which provides a stable mounting base for the entire protective face recognition terminal. Users can choose a suitable installation position and fix the terminal in a suitable place through the mounting plate 7, which facilitates the user's use and operation.

[0035] The implementation principle of this utility model is as follows: First, when the device is not in use, the curtain is moved down by pulling the protrusion 602, which causes the locking block 601 to enter the locking groove 606 and drives the slider 605 to slide in the first slide groove 603. The sliding locking block 601 presses the spring locking block 608 along the inclined surface, causing the spring locking block 608 to move horizontally. When the locking block 601 is fully inserted into the locking groove 606, the spring locking block 608 pops out to fix the curtain 5. When it is needed to be used again, the push rod 609 is pushed along the second slide groove 610 to retract the spring locking block 608. At the same time, the spring 3 drives the roller 4 to rotate to retract the curtain 5. The rubber slider 605 slows down the retraction speed of the curtain 5 and reduces the impact when the curtain 5 is fully retracted.
