Description

Technical Field

[0002] In fields such as industrial automation, logistics sorting, and warehouse management, barcode scanning terminals, as key equipment for information collection, are widely used in various production and distribution processes. With the increasing complexity and diversity of application scenarios, higher demands are placed on the installation adaptability, operational flexibility, and environmental interference resistance of barcode scanning equipment. Traditional barcode scanning terminals often use fixed or simple bracket installations, offering limited adjustment freedom and failing to meet scanning needs at different heights, angles, and working distances, especially performing poorly in space-constrained environments or situations requiring frequent workstation changes. Furthermore, changes in ambient light can easily lead to scanning distortion or misreading, affecting recognition efficiency and accuracy. Additionally, existing equipment often requires disassembling fasteners for maintenance and replacement, making operations cumbersome and reducing maintenance efficiency.

[0003] In existing technologies, traditional barcode scanning terminals are mostly fixed or have only a single degree of adjustment. After installation, the angle and position adjustment are limited, making it difficult to adapt to diverse scanning needs at different heights, angles, or distances. Especially in complex industrial environments, they are easily affected by external light interference and have inaccurate positioning. In addition, barcode scanners usually require tools to disassemble and assemble, making maintenance and replacement inconvenient and affecting work efficiency. Utility Model Content

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0017] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0018] Example Reference Figures 1-4 This embodiment of the present invention provides a light-shielding and anti-interference barcode scanning terminal component that can be adjusted with multiple degrees of freedom, including: The support mechanism 100 includes a base 101, a fixing ring 102 fixedly installed on the outer surface of the base 101, a turntable 103 that slides in contact with the outer surface of the fixing ring 102, and a telescopic rod 104 fixedly installed on the outer surface of the turntable 103. The scanning mechanism 200 includes an adjusting arm 201 fixedly installed on the outer end face of the telescopic rod 104, a hinge block 202 hingedly installed with the adjusting arm 201, a connecting block 203 hingedly installed with the hinge block 202, a barcode scanner 204 disposed at the end of the connecting block 203, a limiting component 205 for limiting the turntable 103, and a quick-release component 206 for disassembling the barcode scanner 204. The limiting assembly 205 includes a limiting wheel 205a rotatably connected to the base 101, a limiting block 205b meshing with the surface of the limiting wheel 205a, and a first spring 205c fixedly connected to the outer surface of the limiting block 205b.

[0019] When the horizontal rotation angle of the barcode scanner needs to be adjusted, the user can manually rotate the turntable 103. The turntable 103 drives the limiting wheel 205a, which is fixedly connected to it, to rotate synchronously. During the rotation, the limiting block 205b, under the elastic force of the first spring 205c, always maintains elastic engagement with the outer surface of the limiting wheel 205a, providing damping and indexing positioning effects. When the turntable 103 rotates to the target angle, the limiting block 205b re-embeds into the adjacent positioning groove of the limiting wheel 205a, realizing the re-limiting and angle locking of the turntable 103, ensuring that the barcode scanner 204 maintains a stable posture after adjustment, and preventing positional deviation caused by vibration or external force.

[0020] Specifically, the quick-release assembly 206 includes a fixed frame 206a fixedly installed on both sides of the outer surface of the connecting block 203, a second spring 206b fixedly connected to the inner surface of the fixed frame 206a, a pull ring 206c fixedly connected to the other end of the second spring 206b, and a pin 206d that slides in contact with the inner surface of the fixed frame 206a.

[0021] When the barcode scanner 204 needs to be disassembled, the operator pulls the pull ring 206c outward. The pull ring 206c moves along the sliding direction on the inner surface of the fixed frame 206a, causing the pin 206d to retreat synchronously against the elastic force of the second spring 206b. As the pin 206d exits the slot on the outer surface of the barcode scanner 204, the locking state between the two is released, realizing the quick disassembly and disassembly of the barcode scanner 204.

[0022] Furthermore, a bearing sleeve is provided at the connection between the limiting wheel 205a and the base 101 to cooperate with the rotation of the two, and the limiting wheel 205a is fixedly connected to the turntable 103.

[0023] Furthermore, the other end of the first spring 205c is fixedly connected to the inner surface of the fixing ring 102, and the limiting blocks 205b are evenly distributed in a ring on the outer surface of the limiting wheel 205a.

[0024] Furthermore, two sets of quick-release components 206 are symmetrically arranged on both sides of the connecting block 203.

[0025] Preferably, the pull ring 206c is rotatably connected to the inner surface of the fixed frame 206a, and the outer surface of the pull ring 206c is in contact with the inner surface of the pin 206d.

[0026] It should be noted that the outer surface of the pin 206d slides in conjunction with the inner surface of the fixing frame 206a, and the outer surface of the barcode scanner 204 has a slot for use with the pin 206d.

[0027] In use, the support mechanism 100 is first stably installed on the workbench or operating equipment via the base 101. When it is necessary to adjust the scanning angle and distance to adapt to the needs of different workstations, the user can manually rotate the turntable 103 horizontally. The turntable 103 drives the limit wheel 205a, which is fixedly connected to it, to rotate synchronously, thereby realizing the overall horizontal orientation adjustment of the scanning mechanism 200. During this process, the limit block 205b, under the elastic force of the first spring 205c, always maintains elastic engagement with the positioning groove on the outer surface of the limit wheel 205a, providing moderate rotational damping and clear indexing feedback, allowing the operator to accurately perceive the adjustment angle. When the turntable 103 rotates to the target position, the limit block 205b automatically embeds into the adjacent positioning groove, completing the limit locking of the turntable 103, ensuring that the scanner 204 maintains a stable posture during operation, preventing displacement due to external vibration or accidental touch. At the same time, the telescopic rod 104 can move axially... The distance between the scanner 204 and the object being scanned can be adjusted by stretching or retracting the scanner to adapt to different depth-of-field scanning requirements. In addition, the adjustment arm 201, hinge block 202, and connecting block 203 form a pitch adjustment degree of freedom through the hinge structure. The user can manually move the scanner 204 to make fine adjustments to the up and down angle, and rely on the frictional resistance at the hinge to maintain the set angle. When the scanner 204 needs to be replaced, maintained, or cleaned, the operator only needs to pull the pull rings 206c on both sides outward. The pull rings 206c slide in the fixed frame 206a and drive the pin 206d to overcome the elastic force of the second spring 206b and move it back, so that the pin 206d disengages from the slot on the outer surface of the scanner 204, thereby releasing the locked state. The scanner 204 can then be quickly removed from the connecting block 203. When installing, the operation is reversed. After the scanner 204 is pushed into place, the pin 206d automatically engages with the slot under the action of the second spring 206b, achieving reliable locking.

[0028] In summary, by setting up a multi-degree-of-freedom adjustment structure, including a horizontally rotatable turntable 103, pitch-adjustable articulated arms 201, 202, and 203, and a telescopic rod 104, the barcode scanner terminal can be flexibly adjusted in multiple directions in space, effectively adapting to the height, angle, and distance requirements of different workstations. Combined with the elastic engagement positioning structure of the limit component 205, reliable position locking after adjustment is ensured, preventing vibration-induced displacement. Meanwhile, the quick-release component 206 adopts a tool-free disassembly structure with a linkage between the pin 206d and the spring 206b, enabling rapid replacement and maintenance of the barcode scanner 204, thus improving the applicability and operational efficiency of the barcode scanner terminal in complex industrial environments.
