Description

Technical Field

[0001] This utility model relates to the field of QR code scanner technology, specifically a QR code scanner with an adjustable structure. Background Technology

[0002] With the rapid development of mobile payment, logistics management, and product traceability, QR codes, as an efficient information carrier, have been widely used in various scenarios. As the core device for reading QR code information, the ease of use and scanning stability of QR code scanners have become key factors affecting work efficiency.

[0003] A search revealed that patent publication number CN208335204U discloses a QR code scanner, comprising a base and a scanner head. A rod core is slidably connected to the upper end of the base, and a first fastening bolt is fixedly installed on the upper side of the base. A rotating rod is rotatably connected to the upper end of the rod core, and a second fastening bolt is fixedly installed on the upper side of the rod core. A storage cap is fixedly connected to the upper end of the rotating rod. A temperature sensor is fixedly installed on the left side of the scanner head, with several probes of the temperature sensor distributed inside the scanner head. An alarm indicator light is fixedly installed on the top of the scanner head. A scanning port is opened on the front end of the scanner head. A handle is fixedly connected to the lower end of the scanner head, and a protective layer is fixedly connected to the rear end of the handle. A switch is fixedly installed on the front end of the handle, and an anti-slip textured layer is provided on the front end of the handle. This invention significantly improves the safety of the QR code scanner, preventing excessive internal heat generated during prolonged operation, thereby protecting the internal components of the scanner and avoiding damage.

[0004] The scanning performance of existing QR code scanners is easily affected by ambient light. In dimly lit scenes, the built-in supplementary lighting devices of existing scanners often have limited coverage and uneven light distribution, resulting in blurry QR code images and insufficient contrast, which in turn affects scanning speed and recognition success rate. Although some scanners are equipped with supplementary lighting components, the supplementary lighting angle cannot be precisely matched with the scanning beam, resulting in unsatisfactory supplementary lighting effects and difficulty in meeting the scanning needs in complex environments. More importantly, in existing technologies, even if the angle of some scanners and supplementary lighting components can be adjusted separately, they lack a coordinated design. When the angle of the scanner is adjusted to align with QR codes in different positions, the supplementary lighting component cannot move synchronously, often causing the supplementary light to deviate from the extension direction of the scanning beam. This results in the supplementary lighting not accurately covering the scanning area and may even cause problems such as light spots and reflections due to improper light angles, further interfering with the scanning effect and seriously affecting the stability and efficiency of scanning. Therefore, a QR code scanner with an adjustable structure is designed. Utility Model Content

[0005] In view of the defects or shortcomings of existing QR code scanners, the purpose of this utility model is to provide a QR code scanner with an adjustable structure, which can not only adjust the scanning angle of the wireless scanner according to the position of the QR code, but also realize the synchronous operation of the wireless scanner and the ring-shaped auxiliary light.

[0006] To achieve the above-mentioned objectives, the present invention adopts the following technical solution:

[0007] This utility model provides a QR code scanner with an adjustable structure, including a wireless scanner for scanning QR codes. The wireless scanner is mounted on an automatic sensing bracket adapted to it. The wireless scanner has a ring-shaped fill light for supplementing light in the extension direction of its scanning beam. An adjustment component for adjusting the tilt angle of the ring-shaped fill light and the automatic sensing bracket is provided below the automatic sensing bracket.

[0008] Preferably, the adjustment assembly is composed of a turbine, a worm gear, a rotating adjustment plate, a housing, and a base. Both the turbine and the worm gear are located inside the housing, and the worm gear is located above the worm gear.

[0009] Preferably, the two ends of the turbine are respectively installed in bearings on the two end walls of the housing, the two ends of the worm are respectively installed in bearings on the two outer walls of the housing, and a rotation adjustment plate is installed at one end of the worm. The housing is installed on the top of the base.

[0010] Preferably, the front and rear ends of the outer wall of the automatic sensing bracket are provided with first connecting rods, and the other ends of the two first connecting rods are respectively installed on the two end walls of the turbine.

[0011] Preferably, a second connecting rod is provided on the first connecting rod, and the other end of the second connecting rod is provided on the circumferential outer wall of the annular fill light.

[0012] Compared with existing technologies, one or more of the above technical solutions have the following beneficial effects:

[0013] 1. In this utility model, through a series of coordinated structural arrangements, the wireless scanner is equipped with a ring-shaped supplementary light in the extension direction of its scanning beam. This design allows the supplementary light range to be precisely matched with the scanning beam, and the light distribution to be more uniform. It can provide sufficient and suitable illumination for QR codes in dim or complex lighting environments, avoiding problems such as blurry QR code images and insufficient contrast caused by insufficient light. This significantly improves scanning speed and recognition accuracy, and ensures stable operation under various lighting conditions.

[0014] 2. In this utility model, through a series of coordinated structural arrangements, the adjustment component can adjust the tilt angle of the ring-shaped fill light and the automatic sensing bracket. This allows the scanning angle of the wireless scanner to be adjusted according to the position of the QR code. When the wireless scanner is tilted by the adjustment component, the wireless scanner and the ring-shaped fill light can move synchronously, ensuring that the ring-shaped fill light is always located in the extension direction of the scanning beam. This prevents problems such as fill light shift, local dimness or overbrightness due to angle changes, thus maintaining a good fill light effect and ensuring the clarity and stability of the scan.

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0027] It should be noted that the following detailed description is exemplary and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0028] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise.

[0029] like Figure 1-5 As shown, a QR code scanner with an adjustable structure includes a wireless scanner 100 for scanning QR codes. The wireless scanner 100 is mounted on an automatically sensing bracket 200 adapted to it. Mounting the wireless scanner 100 on the automatically sensing bracket 200 eliminates the need for manual hand-held operation, effectively avoiding hand fatigue during high-frequency, long-term operation and reducing the workload of operators. Simultaneously, the automatic sensing feature allows the wireless scanner 100 to automatically start scanning when a QR code is detected, reducing manual triggering steps and further improving work efficiency. It is particularly suitable for scenarios requiring rapid processing of large numbers of scanning tasks, such as supermarket checkouts and express delivery sorting. The wireless scanner 100 has a ring-shaped supplementary light 300 for supplementary lighting in the extension direction of its scanning beam. An adjustment component 400 for adjusting the tilt angle of the ring-shaped supplementary light 300 and the automatically sensing bracket 200 is located below the automatic sensing bracket 200.

[0030] The adjustment assembly 400 is composed of a turbine 410, a worm gear 420, a rotary adjustment plate 430, a housing 440, and a base 450. Both turbines 410 and worm gear 420 are located inside the housing 440, and the turbine 410 is located above the worm gear 420.

[0031] The two ends of the turbine 410 are respectively installed in the bearings on the two end walls of the housing 440, and the two ends of the worm gear 420 are respectively installed in the bearings on the two outer walls of the housing 440. A rotating adjustment plate 430 is installed on one end of the worm gear 420. The housing 440 is installed on the top of the base 450. When the operator rotates the rotating adjustment plate 430, it will drive the worm gear 420 to rotate. When the worm gear 420 rotates, it will drive the turbine 410 to rotate. When the turbine 410 rotates, it will drive the automatic sensing bracket 200 and the ring-shaped supplementary light 300 to rotate through the first connecting rod 210 and the second connecting rod 220 respectively, thereby synchronously adjusting the tilt angle of the automatic sensing bracket 200 and the ring-shaped supplementary light 300.

[0032] The front and rear ends of the outer wall of the automatic sensing bracket 200 are provided with first connecting rods 210, and the other ends of the two first connecting rods 210 are respectively installed on the two end walls of the turbine 410.

[0033] A second connecting rod 220 is provided on the first connecting rod 210, and the other end of the second connecting rod 220 is provided on the circumferential outer wall of the annular supplementary light 300.

[0034] Working Principle: During use, the adjustment component 400 can adjust the tilt angle of the ring-shaped fill light 300 and the automatic sensing bracket 200. The scanning angle of the wireless scanner 100 can be adjusted according to the position of the QR code. When the wireless scanner 100 is tilted by the adjustment component 400, the wireless scanner 100 and the ring-shaped fill light 300 can move synchronously, ensuring that the ring-shaped fill light 300 is always located in the extension direction of the scanning beam. This prevents problems such as fill light shift, local dimness or overbrightness due to angle changes, thus maintaining a good fill light effect and ensuring the clarity and stability of the scan. The wireless scanner 100 sets the ring-shaped fill light 300 in the extension direction of its scanning beam. This design allows the fill light range to be precisely matched with the scanning beam, and the light distribution is more uniform. It can provide sufficient and suitable illumination for the QR code in dim or complex lighting environments, avoiding problems such as blurry QR code images and insufficient contrast caused by insufficient light. This significantly improves the scanning speed and recognition accuracy, ensuring stable operation under various lighting conditions.

[0035] The above description is merely a preferred embodiment of this utility model and is not intended to limit the invention. For those skilled in the art, various modifications and variations can be made to this invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this invention should be included within the protection scope of this invention.
