Detailed Implementation
[0025] To make the utility model's objectives, features, and advantages more apparent and understandable, the technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of the utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the utility model without creative effort are within the scope of protection of the utility model.
[0026] In the description of this utility model, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component centrally located at the same time.
[0027] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0028] This utility model embodiment provides a dual-screen cash register, such as Figures 1 to 3 As shown, the device includes a cash register base 10, on which a main display screen 20 and a secondary display screen 30 are mounted. The front of the main display screen 20 faces the cashier, and the front of the secondary display screen 30 faces the consumer.
[0029] The main display screen 20 is equipped with a privacy shield 40, which includes a privacy shield platform 41 and a privacy shield plate 42 hinged to the privacy shield platform 41. The privacy shield plate 42 is used to block and protect the main display screen 20 in a first state and to protect the main display screen 20 from peeping in a second state. In this embodiment, the internal control circuit of the cash register base 10, the working principle of the main display screen 20, and the working principle of the secondary display screen 30 are all well-known technologies in the art and will not be described in detail here. A plurality of heat dissipation holes 11 are provided on one side of the cash register base 10. Through the setting of the heat dissipation holes 11, the heat generated inside the cash register base 10 can be quickly discharged to the external space.
[0030] It should be noted that the dual-screen cash register provided by this utility model, by setting an anti-peeping component 40 on the main display screen 20, and the anti-peeping plate 42 in the second state, can limit the viewing angle of the main display screen 20, allowing only the cashier to view the displayed content from the front, thereby preventing surrounding personnel from peeping at sensitive information (such as product costs, cashier operation data, etc.), significantly improving the security and privacy of transaction data. The secondary display screen 30 displays transaction information to the customer, while the main display screen 20 focuses on the cashier's operation and is equipped with an anti-peeping structure, ensuring both transparency and security in the transaction process, reducing customer concerns about data leakage, and thus improving the overall customer experience and trust. Therefore, this utility model solves the problem of main screen data leakage in existing dual-screen cash registers during cashier operations.
[0031] like Figures 1 to 3 A torsion spring (not shown) is installed between the privacy stand 41 and the privacy plate 42.
[0032] In practice, the torsion spring provides damping and a self-centering force for the rotation of the privacy panel 42. When the cashier gently pushes the privacy panel 42, they can feel a clear resistance. After releasing it, the torsion spring stabilizes it in its current position (at any opening angle), preventing it from wobbling or closing due to its own weight or slight contact. The preload of the torsion spring ensures that the privacy panel 42 fits tightly against the privacy stand 41 or the frame of the main display screen 20 when closed. This not only better prevents dust from entering through gaps but also makes the privacy panel 42 more structurally stable and aesthetically pleasing in its first state (covered and protected state).
[0033] like Figure 2 and Figure 3 As shown, the privacy screen 42 includes a first plate 421 hinged to the privacy stand 41, and a second plate 422 slidably embedded in the first plate 421. A push-pull strip 4221 is provided on one side of the second plate 422, and the push-pull strip 4221 and the second plate 422 are integrally formed.
[0034] In practice, when confidential content is displayed on the left half of the main display screen 20, the cashier can pull out only part of the second panel 422 for targeted blocking; when full-screen privacy protection is required, the second panel 422 can be fully pulled out to maximize privacy protection for the main display screen 20, demonstrating strong adaptability. Different checkout environments (such as fast checkout during peak hours and inventory reconciliation during off-peak hours) and different display content (such as a simple payment interface and a complex back-end management system) have different privacy protection needs. This scalable design allows cashiers to quickly and seamlessly adjust the privacy protection range according to real-time needs, achieving dynamic and intelligent privacy protection. When not in use or when simple cleaning and maintenance of the main screen is required, the second panel 422 can be pushed back into the first panel 421. This makes the entire privacy protection component 40 compact, minimizing its space occupation, avoiding the inconvenience that a bulky integrated privacy panel 42 might cause, and also making the overall appearance of the cash register more concise. By setting the push-pull bar 4221, cashiers are provided with a clear and convenient point of force application, making the extension and retraction operation very convenient, without having to look for hidden switches or buttons.
[0035] like Figure 2 and Figure 3 As shown, the privacy screen 41 is provided with an abutment surface 412, which is used to limit and abut against the first plate 421 in the second state.
[0036] In practice, when the privacy panel 42 is in the second state, a stable triangular support structure is formed through the contact between the abutment surface 412 and the first plate 421. This significantly improves the rigidity of the entire privacy assembly 40, effectively preventing it from shaking due to slight impacts or hand pressure on the screen during operation, thus enhancing the device's stability and perceived quality. The abutment surface 412 bears the main external force (such as excessive pressure unintentionally applied by the user) when the privacy panel 42 is in the open state. It disperses and cancels out this force, preventing the force from acting entirely on the hinge and the internal torsion spring.
[0037] like Figure 2 and Figure 3 As shown, the privacy screen 41 has a first mounting groove 411 inside, and the main display screen 20 has a second mounting groove 21 on one side corresponding to the first mounting groove 411; a first magnetic block 50 is installed in the first mounting groove 411, and a second magnetic block 60 that is magnetically connected to the first magnetic block 50 is installed in the second mounting groove 21.
[0038] In practice, the magnetic connection between the first magnetic block 50 and the second magnetic block 60 allows cashiers or maintenance personnel to easily remove the entire privacy shield 40 from the main display screen 20 by hand without any tools, enabling quick disassembly and assembly. The magnetic blocks are hidden within the first mounting slot 411 and the second mounting slot 21, making the connection interface seamless and flat, with no visible screw holes or clips, thus enhancing the overall appearance and aesthetics of the product.
[0039] like Figures 1 to 3 As shown, the number of privacy protection components 40 is set to two, and the two privacy protection components 40 are distributed on opposite sides of the main display screen 20.
[0040] In practical implementation, by setting up two privacy shields 40, a visual barrier can be simultaneously formed from the left and right sides of the main display screen 20, greatly reducing the viewing angle and creating a safer and more comprehensive visual isolation zone, effectively preventing data leakage from any side. The cash register may have multiple light sources (such as overhead lights and windows), which can easily cause glare and reflections on the screen. The two privacy shields 42 not only prevent peeping but also act as physical light shields, effectively blocking stray light from different directions from hitting the screen, thereby enhancing screen contrast, reducing cashier eye strain, and allowing them to see the displayed content more clearly.
[0041] like Figures 1 to 3 As shown, the lengths of the two privacy screens 42 are greater than or equal to the length of the main display screen 20. In practice, because the lengths of the two privacy screens 42 are greater than or equal to the length of the main display screen 20, it ensures that the horizontal coverage of the privacy screens 42 completely matches or even exceeds the display area of the main display screen 20, thus completely eliminating the possibility of peeping at the screen content from any position on the left or right sides of the screen.
[0042] Working Principle: This utility model provides a dual-screen cash register. By installing an anti-peeping component 40 on the main display screen 20, the anti-peeping plate 42, in its second state, restricts the viewing angle of the main display screen 20, allowing only the cashier to view the displayed content from the front. This prevents surrounding personnel from peeping at sensitive information (such as product costs, cashier operation data, etc.), significantly improving the security and privacy of transaction data. The secondary display screen 30 displays transaction information to the customer, while the main display screen 20 focuses on cashier operations and is equipped with an anti-peeping structure, ensuring both transparency and security in the transaction process. This reduces customer concerns about data leakage, thereby improving the overall customer experience and trust. Therefore, this utility model solves the problem of main screen data leakage in existing dual-screen cash registers during cashier operations.
[0043] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
