[0002] With the rapid development of mobile payment and intelligent recognition technologies, QR codes are becoming increasingly popular. Scanning boxes, as an important QR code reader, play a key role in various commercial scenarios and daily life. However, existing scanning boxes are typically fixed in size, making them difficult to adapt to different QR code sizes and placement.

[0003] The utility model patent with authorization announcement number CN216352326U discloses a portable code scanning box, including an upper shell, a lower shell, a PCBA mainboard, a camera structure and a data cable structure. One end of the upper shell is buckled with one end of the lower shell, and the upper shell and the lower shell are surrounded by a receiving cavity. The PCBA mainboard and the camera structure are both placed in the receiving cavity. The other end of the upper shell is provided with a camera hole recessed toward the lower shell. One end of the camera structure and one end of the data cable structure are electrically connected to the PCBA mainboard respectively. The other end of the camera structure is fixed on the PCBA mainboard and extends out of the camera hole. The other end of the data cable structure extends out of the receiving cavity.

[0031] The present application will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely for the purpose of explaining the relevant utility model and are not intended to limit the utility model. It should also be noted that, for ease of description, only the portions relevant to the utility model are shown in the accompanying drawings.

[0032] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0033] See also Figures 1-4 The size-adaptable barcode scanning box includes a base 1, an inner shell 2 is provided on the top surface of the base 1, and the inner shell 2 is slidably connected to the outer shell 3 through a plurality of T-shaped slots 21 provided on the outer wall thereof. A scanning camera 4 is installed at the center of the bottom surface of the inner shell 2, and a PCBA mainboard 5 connected to the scanning camera 4 via a signal line is installed inside the inner shell 2. A fixing component 9 is provided at the bottom end of the base 1;

[0034] The fixing assembly 9 includes a threaded rod 91 rotatably connected to the base 1, and a threaded block 92 is threadedly connected to the threaded section of the threaded rod 91. An outer support rod 93 is hinged at the center of the two opposite side walls of the threaded block 92, and a fixing plate 94 is hinged at one end of the outer support rod 93 away from the threaded block 92.

[0035] In this embodiment, T-shaped sliders 34 that match the size of the T-shaped slide grooves 21 and correspond in position to each other are welded and fixed to the bottom ends of the four inner side walls of the outer shell 3. A screw rod 6 is rotatably connected to one of the T-shaped slide grooves 21, and a first threaded hole that matches it is opened in the middle of the T-shaped slider 34 near the screw rod 6; the matching T-shaped slide grooves 21 and T-shaped sliders 34 allow the outer shell 3 to slide up and down along the side walls of the inner shell 2, and the rotation of the screw rod 6 drives the corresponding T-shaped slider 34 to slide up and down along the T-shaped slide groove 21.

[0036] Furthermore, a second gear 8 is welded and fixed to the bottom end of the screw rod 6, and a second motor 10 is installed on one side of the top surface of the base 1. The output shaft of the second motor 10 is coaxially connected to the first gear 7, and the first gear 7 is meshed with the second gear 8; the second motor 10 drives the first gear 7 to rotate, and then drives the second gear 8 to rotate, thereby causing the screw rod 6 to rotate.

[0037] Secondly, an LED lamp 32 is installed at the top surface of the shell 3 near the edge through a lamp groove 31, and a glass plate 33 is installed at the upper end of the inner wall of the shell 3 through a card slot; the LED lamp 32 is designed to scan the QR code for fill light, and the glass plate 33 protects the scanning camera 4.

[0038] Furthermore, a second threaded hole 921 is provided at the center of the threaded block 92, which is compatible with the threaded section of the threaded rod 91. A hinge seat 95 is welded and fixed to the center of the side wall of the threaded block 92 near the outer support rod 93, and a hinge seat 95 is welded and fixed to the center of the side wall of the fixing plate 94 near the outer support rod 93. Both ends of the outer support rod 93 are welded and fixed with hinge protrusions compatible with the hinge seat 95; the design of the second threaded hole 921 enables the threaded block 92 to be threadedly connected to the threaded rod 91, and the matching hinge seat 95 and hinge protrusion enable the two ends of the outer support rod 93 to be hinged to the fixing plate 94 and the threaded block 92 respectively.

[0039] Secondly, a first motor 96 is installed on one side wall of the base 1, and the output shaft of the first motor 96 is coaxially connected to the threaded rod 91. Slide rods 941 are welded and fixed at both ends of the side wall of the fixed plate 94 close to the base 1. The side wall of the base 1 close to the fixed plate 94 is provided with a hole groove 11 that is adapted to the size of the slide rod 941 and corresponds to the position one by one; the first motor 96 provides power for the rotation of the threaded rod 91, and the slide rod 941 is designed to limit the movement of the fixed plate 94.

[0040] Furthermore, when the threaded block 92 slides to the head end of the threaded section of the threaded rod 91, the fixing plate 94 retracts into the groove opened on the side wall of the base 1; when the threaded block 92 slides to the end of the threaded section of the threaded rod 91, the outer support rod 93 and the threaded rod 91 are in a vertical state; retracting into the base 1 allows the fixing plate 94 to obtain the minimum size at the bottom end of the scanning box after it is fully retracted, and the vertical state allows the fixing plate 94 to slide outward to the maximum distance.

[0041] Working principle: When using the scanning box with adaptively adjustable size of the present invention, the user first places the scanning box into the groove of the desktop, and then drives the first motor 96 to drive the threaded rod 91 to rotate, so that the threaded block 92 slides along the threaded rod 91 to the end, thereby increasing the angle between the outer support rod 93 and the threaded rod 91, and the fixing plate 94 extends outward to effectively fix the scanning box. When the size of the QR code to be scanned is too large, the second motor 10 is driven to drive the first gear 7 to rotate, so that the second gear 8 rotates, thereby causing the screw 6 to rotate, causing the shell 3 to slide downward, thereby increasing the scanning range of the scanning camera 4. When the size of the QR code to be scanned is too small, the shell 3 slides upward, thereby reducing the scanning range of the scanning camera 4.

[0042] The above description is merely a preferred embodiment of the present application and an illustration of the technical principles employed. Those skilled in the art should understand that the scope of the utility model disclosed in this application is not limited to the technical solutions formed by the specific combination of the above-mentioned technical features, but also encompasses other technical solutions formed by any combination of the above-mentioned technical features or their equivalents without departing from the concept of the utility model. For example, a technical solution formed by replacing the above-mentioned features with, but not limited to, technical features having similar functions disclosed in this application.
