[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-8 This utility model provides a foldable, anti-drop QR code scanning device, including an arc-shaped plate 4, a limiting groove 10 on the top surface of the arc-shaped plate 4, a mounting frame 7 on the top surface of the arc-shaped plate 4, and the mounting frame 7 being movably connected to the arc-shaped plate 4. A folding groove 9 is provided on the top surface of the mounting frame 7, and positioning holes 8 are arrayed on the inner side of the folding groove 9. A Velcro strap 2 is arrayed and fixed on the top surface of the arc-shaped plate 4, and an anti-slip strip 3 is arrayed and fixed on the inner side of the arc-shaped plate 4. The anti-slip strip 3 is made of thermoplastic rubber. It also includes an adjustment component 11, which is set in the folding groove 9 for storing the scanning device and adjusting its position and angle.

[0024] Specifically, the device can be worn on the user's arm via the curved plate 4, the mounting frame 7 can be moved and positioned on the curved plate 4, and the adjustment component 11 can not only be folded and stored in the mounting frame 7, but also adaptively adjust the scanning angle of the device according to the user's habits. These designs allow the device to be folded and worn on the user's arm, freeing the user's hands, improving the scanning efficiency of the device, enabling the device to be used in confined spaces, and preventing the device from falling from the hand, thus improving the practicality of the device.

[0025] The adjustment assembly 11 includes a support plate 101, a mounting groove 103 is provided on one side of the support plate 101, a barcode scanner 104 is provided in the mounting groove 103, and a rotation damping shaft 110 is provided between the barcode scanner 104 and the mounting groove 103.

[0026] It should be noted here that the rotary damping shaft 110 is a mechanical component used to control the rotational motion of a foldable anti-drop QR code scanning device. It slows down or stops the rotational motion by providing damping force, while protecting the sensitive components in the device. As prior art in this application, its working principle and operation method will not be described in detail here.

[0027] Specifically, after the support plate 101 is rotated out of the folding slot 9, the scanning angle of the barcode scanner 104 is adjusted. By adjusting the damping force of the rotating damping shaft 110, the rotational movement of the barcode scanner 104 is made smoother, avoiding sudden acceleration or deceleration, and the barcode scanner 104 can be stopped at any position.

[0028] The support plate 101 has guide grooves 105 on its front and back sides respectively. A guide block 108 is provided in the guide groove 105 and the guide block 108 is movably connected to the guide groove 105. A return spring 109 is fixed between the guide block 108 and the guide groove 105.

[0029] Specifically, the guide groove 105 limits the rotation of the guide block 108. The guide block 108 can only move horizontally in the guide groove 105 and cannot rotate. Under the action of the reset spring 109, the guide block 108 in the guide groove 105 can spring back to its original position.

[0030] Positioning posts 106 are fixed on the surface array of the guide block 108, and the positioning posts 106 are engaged with the positioning holes 8. Pressing blocks 102 are provided on the front and back of the support plate 101. Connecting posts 107 are fixed between the pressing blocks 102 and the guide block 108, and the connecting posts 107 pass through the mounting frame 7 respectively.

[0031] Specifically, during the rebound of the guide block 108, the positioning post 106 connects with the positioning hole 8 inside the folding groove 9, thereby fixing the angle of the support plate 101.

[0032] A limiting block 12 is fixed on the bottom surface of the arc plate 4, and the limiting block 12 is movably connected to the limiting groove 10. The inner side of the limiting groove 10 is provided with a positioning groove 6. The two sides of the limiting block 12 are respectively provided with telescopic grooves 13. A positioning ball 15 is provided in the telescopic groove 13, and the positioning ball 15 is movably connected to the telescopic groove 13 and the positioning groove 6 respectively. A telescopic spring 14 is fixed between the positioning ball 15 and the telescopic groove 13.

[0033] Specifically, by applying a certain force, the limiting block 12 on the bottom surface of the mounting frame 7 can move in the limiting groove 10. During the movement, the positioning ball 15 is subjected to pressure and will squeeze the telescopic spring 14 into the telescopic groove 13. When the position of the mounting frame 7 is determined, the positioning ball 15 is connected to the positioning groove 6 under the action of the telescopic spring 14.

[0034] A flexible strip 11 is fixed to the bottom surface of the curved plate 4, and a control button 5 is embedded on the side of the flexible strip 11;

[0035] Specifically, the flexible strip 11 has a certain degree of rigidity. When using the device, the user can hold the flexible strip 11 with their thumb and four fingers. When scanning is required, the user can press the control button 5 on the side of the flexible strip 11 by bending their four fingers to perform the scanning action.

[0036] Working principle: After the support plate 101 is rotated out of the folding groove 9, the scanning angle of the barcode scanner 104 is adjusted. By adjusting the damping force of the rotating damping shaft 110, the rotational movement of the barcode scanner 104 is made smoother, avoiding sudden acceleration or deceleration, and allowing the barcode scanner 104 to stop at any position. The guide groove 105 limits the rotation of the guide block 108. The guide block 108 can only move horizontally in the guide groove 105 and cannot rotate. Under the action of the return spring 109, the guide block 108 in the guide groove 105 can spring back to its original position. During the springback process of the guide block 108, the positioning post 106 and... The positioning hole 8 inside the folding groove 9 is connected to fix the angle of the support plate 101. By applying a certain force, the limiting block 12 on the bottom surface of the mounting frame 7 can move in the limiting groove 10. During the movement, the positioning ball 15 is pressured and squeezes the telescopic spring 14 into the telescopic groove 13. When the position of the mounting frame 7 is determined, the positioning ball 15 is connected to the positioning groove 6 under the action of the telescopic spring 14. The flexible strip 11 has a certain degree of rigidity. When using the device, the user can hold the flexible strip 11 with their thumb and four fingers. When scanning is required, the user can press the control button 5 on the side of the flexible strip 11 by bending their four fingers to realize the scanning action.

[0037] The device can be worn on the user's arm via the curved plate 4. The mounting frame 7 can be moved and positioned on the curved plate 4. The adjustment component 11 can not only be folded and stored in the mounting frame 7, but also adaptively adjust the scanning angle of the device according to the user's habits. These designs allow the device to be folded and worn on the user's arm, freeing the user's hands, improving the scanning efficiency of the device, enabling the device to be used in confined spaces, and preventing the device from falling from the hand, thus improving the practicality of the device.

[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
