Description

Technical Field

[0001] This utility model relates to the field of display equipment technology, and in particular to a QR code display device. Background Technology

[0002] QR codes, also known as two-dimensional barcodes, are a type of encoding method that has become extremely popular on mobile devices in recent years, especially in QR code payments, where they have replaced traditional paper money and made payments more convenient. For ease of use, QR codes are often embedded in display devices.

[0003] Currently, all existing QR code display devices are custom-made. Merchants provide the QR code, and manufacturers perform injection molding to seal the QR code inside the display device at the time of shipment. However, this method has a drawback: merchants cannot replace it themselves. If they need to change the QR code later, they need to replace the entire display device, which is extremely inconvenient. Therefore, in order to better address the above problems and enable the display device to have the ability to change codes, this application proposes a QR code display device that is different from the existing technology. Utility Model Content

[0004] The purpose of this invention is to solve the problem that existing QR code display devices do not have the ability to easily change codes, and to propose a QR code display device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A QR code display device includes a display rack with grooves on both sides. A plurality of first magnetic posts are embedded in the inner wall of one side of the groove. An inner plate is snapped into the groove. An adhesive groove is provided on one side of the inner plate. A plurality of through holes are provided on one side of the inner plate. An outer cover plate is provided on the outer side of the inner plate. A plurality of second magnetic posts are fixedly connected to the inner side of the outer cover plate. The second magnetic posts pass through the through holes and attract the first magnetic posts. Through holes are provided on both sides of the outer wall of the display rack.

[0007] Furthermore, a transparent plate is embedded on one side of the outer cover plate.

[0008] Furthermore, the display stand has a triangular structure.

[0009] Furthermore, two anti-slip pads are fixedly connected to the bottom inner wall of the display rack.

[0010] Furthermore, the diameter of the through hole is 2.0cm-3.0cm.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. By attaching the QR code display paper to the adhesive groove, and then passing the second magnet post of the outer cover plate through the perforation to attract the first magnet post, the QR code display paper is sealed and pressed in place. This installation method allows the QR code to be replaced, improving its practicality.

[0013] 2. Through the perforation and its placement, it not only has strong concealment, but also allows the inner plate to be pushed out with a finger, separating the first and second magnetic pillars, so that the new QR code can be placed on top of the old QR code, thus quickly replacing the QR code and improving the effectiveness of QR code usage.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Reference Figures 1-3 A QR code display device includes a display rack 1. Both sides of the display rack 1 are provided with grooves 2. Multiple first magnet posts 3 are embedded in the inner wall of one side of the groove 2. An inner plate 4 is snapped into the groove 2. An adhesive groove 5 is provided on one side of the inner plate 4. Multiple through holes 6 are provided on one side of the inner plate 4. An outer cover plate 8 is provided on the outer side of the inner plate 4. Multiple second magnet posts 9 are integrally formed on the inner side of the outer cover plate 8. The second magnet posts 9 pass through the through holes 6 and attract the first magnet posts 3. The first magnet posts 3 and the second magnet posts 9 are interference fit with the through holes 6, and a slight pressure is required to complete the snapping.

[0020] The first magnet post 3 and the second magnet post 9 are strong magnets with opposite magnetic properties, such as neodymium iron boron magnets, thus ensuring that the adsorption force is stable enough.

[0021] The QR code display paper 7 is glued into the adhesive groove 5. Then, the second magnet post 9 of the outer cover plate 8 is passed through the perforation 6 and attracted to the first magnet post 3, thereby sealing and pressing the QR code display paper 7.

[0022] A transparent plate 10 is embedded on one side of the outer cover plate 8, through which customers scan the QR code on the display paper 7.

[0023] Display rack 1 has a triangular structure, which improves the stability of the display device.

[0024] Two anti-slip pads 21 are glued to the bottom inner wall of the display rack 1, which increases the friction between the display rack 1 and the supporting surface and improves the stability of the display rack 1.

[0025] The diameter of the through hole 11 is 2.0cm-3.0cm, which is a size that allows for easy finger insertion.

[0026] The working principle of this embodiment is as follows: When in use, firstly, the QR code display paper 7 is glued into the adhesive groove 5. Then, the second magnet post 9 of the outer cover plate 8 is passed through the through hole 6 and attracted to the first magnet post 3. The outer cover plate 8 is flush with the plane of the display frame 1, thereby sealing and pressing the QR code display paper 7, thus completing the installation of the QR code display paper 7.

[0027] When in use, the customer scans the QR code on the display paper 7 through the transparent panel 10;

[0028] When it is necessary to replace the QR code display paper 7, insert your finger into the through hole 11 and apply pressure, which will push the inner plate 4 outward, causing the first magnet post 3 and the second magnet post 9 to separate, and then the inner plate 4 to separate from the groove 2. The new QR code can then be placed on top of the old QR code, which can quickly replace the QR code. It is convenient and fast.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
