Description

Technical Field

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

[0002] QR code protection devices in cigarette sales scenarios are mostly transparent, wear-resistant shells or waterproof coated protective covers that are compatible with cigarette cabinet display codes and cigarette box identification codes. They can resist scratches, oil fumes and dust pollution in the retail environment, prevent the traceability QR codes, which are like the "digital ID cards" of cigarettes, from becoming blurred or damaged, and avoid the risk of malicious tampering. This device ensures the smooth operation of scanning for authenticity and circulation traceability, helps supervision and consumer verification, and safeguards sales order and consumer trust.

[0003] Traditional devices offer simple protection, but dust, rain, and oil can easily seep in, causing the QR code to become blurred or stained when damp. Furthermore, the hard contact when the flip cover is closed can easily scratch the surface of the QR code. Most devices rely on screws or tight-fitting clips for fixation, and replacing the QR code requires unscrewing the screws or forcefully prying the clips, which is cumbersome and can easily cause the screws to strip or the clips to break, making it difficult to fix them stably in the future. Most devices are fixed by a single clip or magnet, and the clips are prone to loosening due to wear, while the magnets lose their attractiveness over time. Utility Model Content

[0022] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0023] Reference Figure 1-5 This utility model provides a QR code protection device, which includes a fixing plate 1, a flip cover 2 on one side of the fixing plate 1, a hinge 5 between the fixing plate 1 and the flip cover 2, a QR code fitting groove 3 inside the fixing plate 1, and a first placement groove 7 inside the fixing plate 1.

[0024] Specifically, the fixed plate 1 serves as the basic support carrier for the entire device, and all components are installed based on it. The hinge 5 enables the flip cover 2 to rotate around the fixed plate 1. When the flip cover 2 is closed, it can cover the internal QR code, preventing the QR code from being directly exposed to the outside. When closed, there is no need to open the flip cover 2. The QR code in the QR code fitting groove 3 can be directly scanned through the transparent material. The QR code fitting groove 3 embeds the QR code by opening a groove, preventing the QR code from shifting or sliding inside the device. The first placement groove 7 can better place the first rubber strip 6.

[0025] Multiple limiting holes 8 are symmetrically opened at the four corners inside the fixed plate 1 and the flip cover 2, and magnets 11 are fixedly connected inside each limiting hole 8.

[0026] Specifically, the limiting hole 8 allows for better installation of the magnet 11, and the magnetic force enables the flip cover 2 to be attracted and fixed to the fixing plate 1.

[0027] A rubber strip 6 is fixedly connected inside the No. 1 placement slot 7.

[0028] Specifically, the elasticity of rubber strip 6 can fill the gaps in the placement groove, serving as a dustproof and waterproof function.

[0029] A protective groove 10 is provided between the QR code fitting groove 3 and the limiting hole 8, and a second rubber strip 9 is fixedly connected inside the protective groove 10.

[0030] Specifically, the protective groove 10 separates the QR code fitting groove 3 from the external area, preventing impurities from the external periphery from directly spreading to the QR code area. The second rubber strip 9 can fill the protective groove 10 to prevent dust, water, oil, etc. from seeping into the QR code fitting groove 3 through the limiting hole 8 or the gap between the flip cover 2 and the fixing plate 1, thus preventing the QR code from being contaminated or damaged by moisture. When the flip cover 2 is closed, the second rubber strip 9 can reduce the hard contact impact between the flip cover 2 and the fixing plate 1, indirectly protecting the surface of the QR code.

[0031] Two slides 12 are symmetrically opened below the fixed plate 1, and each slide 12 is fitted with a movable pin 4.

[0032] Specifically, the slide 12 provides a sliding track for the movable pin 4, restricting the movable pin 4 to move only in a straight line in the locking or unlocking direction. The movable pin 4 achieves locking or unlocking with the flip cover 2 by sliding within the slide 12.

[0033] The fixed plate 1 has a second placement slot 17 inside, and a sleeve 14 is fixedly connected inside the second placement slot 17. A telescopic rod 16 is movably fitted inside the sleeve 14. The other side of the telescopic rod 16 is fixedly connected to a movable pin 4. A spring 18 is movably fitted outside the sleeve 14. A limit groove 15 is opened inside the movable pin 4.

[0034] Specifically, the second placement slot 17 can better accommodate internal components such as sleeve 14, telescopic rod 16 and spring 18. The sleeve 14 and telescopic rod 16 can restrict the movable pin 4 to slide only along the axis of sleeve 14. Spring 18 can provide elastic restoring force. Limiting slot 15 is used to engage with limiting hook 13 of flip cover 2.

[0035] A limit hook 13 is fixedly connected to the bottom of the flip cover 2, and the limit hook 13 is engaged with the limit groove 15.

[0036] Specifically, the limiting hook 13 moves downward with the flip cover 2 and aligns with the limiting groove 15 of the movable pin 4. The limiting hook 13 is engaged in the limiting groove 15 of the movable pin 4, and the flip cover 2 and the fixing plate 1 are forcibly fixed by mechanical engagement.

[0037] Working principle: The fixed plate 1 serves as the basic support carrier. In normal operation, the flip cover 2 is rotated and closed onto the fixed plate 1 via the hinge 5. At this time, the limiting hook 13 below the flip cover 2 engages with the limiting groove 15 of the movable pin 4 in the sliding groove 12 of the fixed plate 1. Simultaneously, the magnets 11 in the limiting holes 8 at the four corners of the fixed plate 1 and the flip cover 2 achieve auxiliary adsorption through magnetic force. This dual action ensures that the flip cover 2 is stably closed. In the closed state, there is no need to open the flip cover 2. The QR code in the QR code fitting groove 3 can be directly scanned through the transparent material. The groove structure of the QR code fitting groove 3 can prevent the QR code from shifting or sliding within the device. When it is necessary to place or remove the QR code, push the movable pin 4 inward. The movable pin 4 slides along the sliding groove 12, causing the telescopic rod 16 connected to it to slide synchronously in the sleeve 14 in the second placement groove 17. The spring 18 outside the sleeve 14 is compressed, and the limiting groove 15 and the limiting hook 13 are disengaged. At this time, the flip cover can be opened around the hinge 5. 2. The QR code fitting groove 3 is exposed for QR code placement or removal. After placement, the flip cover 2 is rotated in the opposite direction to close it, the movable pin 4 is released, the spring 18 elastically resets and pushes the telescopic rod 16 to move the movable pin 4 back along the slide groove 12, the limit hook 13 is re-embedded in the limit groove 15 to achieve mechanical locking, and the magnet 11 simultaneously assists in adsorption, completing the closing and fixing of the flip cover 2. In terms of protection, the first rubber strip 6 in the first placement groove 7 of the fixing plate 1 plays a basic role in dust and water protection by elastically filling the gaps, while the protective groove 10 between the QR code fitting groove 3 and the limit hole 8 isolates the QR code area from the outside. The second rubber strip 9 inside it can not only fill the gaps of the protective groove 10 to prevent dust, water, oil and other contaminants from seeping into the QR code fitting groove 3 from the limit hole 8 or the gap between the flip cover 2 and the fixing plate 1, avoiding QR code contamination or moisture damage, but also reduce the hard contact impact between the flip cover 2 and the fixing plate 1 when the flip cover 2 is closed, indirectly protecting the QR code surface.

[0038] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
