[0002] With the development of Internet of Things (IoT) technology, Radio Frequency Identification (RFID) technology has been widely applied in various fields such as logistics management, warehouse inventory, equipment inspection, and asset tracking. Ultra-high frequency (UHF) RFID readers, with their advantages of long reading distance, fast reading speed, and strong anti-interference capabilities, have become important equipment in current RFID systems. In practical applications, wirelessly connecting UHF readers to mobile terminals (such as mobile phones, tablets, and handheld terminals) via Bluetooth technology enables rapid data transmission and remote control, greatly improving the flexibility and efficiency of data collection.

[0003] Existing Bluetooth RFID UHF readers typically include an antenna module, radio frequency module, Bluetooth communication module, control processing unit, and battery power module. Their overall structure is compact and easy to carry. These devices usually connect to mobile terminals via Bluetooth to read and write RFID tags, and are equipped with features such as OLED displays or status indicators to provide feedback on their operating status. Some devices also support multi-tag recognition, frequency band switching, and batch data uploading to meet diverse application needs. However, in practical use, existing Bluetooth RFID UHF readers are usually fixed in place, lacking a flexible and convenient angle adjustment structure. This makes it difficult to quickly adjust the reader's angle according to user needs in different operating environments. Therefore, this paper proposes a Bluetooth RFID UHF reader to address these issues. Utility Model Content

[0030] 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.

[0031] Reference Figures 1-4 This utility model provides an embodiment of a Bluetooth RFID UHF reader / writer, comprising a reader / writer body 1. The reader / writer body 1 is a Bluetooth RFID UHF reader / writer as described in existing technology, and will not be elaborated further here. It is used to stably install the reader / writer at the target position, ensuring that the device does not shift during operation, thereby improving the stability and reliability of reading and writing. A mounting frame 2 is provided at the bottom of the reader / writer body 1. An adjustment mechanism is provided inside the mounting frame 2 to enable flexible adjustment of the reader / writer at different angles, facilitating adaptation to different application scenarios and usage requirements. A fixing frame 8 is provided at the top of the mounting frame 2 to support the reader / writer body 1. A quick-release mechanism is provided between the reader / writer body 1 and the fixing frame 8 to enable quick disassembly and assembly of the reader / writer, facilitating maintenance and replacement, and improving the ease of use and work efficiency of the device. The adjustment mechanism includes a sleeve 3, a toothed plate 4, and a toothed plate 5. The sleeve 3 is fixedly connected inside the mounting frame 2, serving to support and protect the internal adjustment components. The toothed plate 4 is fixedly connected inside the sleeve 3. As a reference toothed plate for positioning, toothed plate two 5 is set inside sleeve 3. A sliding rod 6 is fixedly connected to the end face of toothed plate two 5 near toothed plate one 4. The side wall of sliding rod 6 is slidably connected inside toothed plate one 4, allowing toothed plate two 5 to slide back and forth inside sleeve. A limit rod 7 is fixedly connected to the side wall of sleeve 3 to limit the movement of fixing frame 8. A first spring 10 is set inside sleeve 3. One end of the first spring 10 is fixedly connected inside sleeve 3, and the other end of the first spring 10 is in contact with toothed plate two 5 to provide elastic force for automatic reset. In its natural state, the first toothed plate 4 and the second toothed plate 5 of the first spring 10 engage to fix the position. When the first spring 10 is under stress and deformed, the first toothed plate 4 and the second toothed plate 5 separate, thereby allowing the angle of the reader body 1 to be adjusted. One side of the fixing frame 8 is fixedly connected to the side wall of the slide rod 6, and can be adjusted synchronously with the movement of the slide rod. The other side of the fixing frame 8 is slidably connected to the side wall of the limiting rod 7. Through the guidance of the limiting rod, the stability and safety of the adjustment process are ensured, and shaking or displacement is prevented. A push block 9 is fixedly connected to the side wall of the slide rod 6.

[0032] Reference Figure 2 and Figure 5The quick-release mechanism includes a plug 11 and a locking block 14. The plug 11 is fixedly connected to the bottom of the reader / writer body 1, enabling quick installation and removal from the underlying structure, thus improving maintenance efficiency. The side wall of the plug 11 is slidably connected to the inside of the fixing frame 8, ensuring smooth vertical movement of the plug. A fixing tube 12 is fixedly connected to the side wall of the fixing frame 8, providing guide support for the internal sliding structure and enhancing the overall structural stability. A slider 13 is slidably connected inside the fixing tube 12, allowing the slider 13 to reciprocate within the fixing tube 12. The side wall of the locking block 14 is fixedly connected to the slider. The side wall of the 13-slider has a groove 16 inside the insert 11. The side wall of the locking block 14 is connected to the inside of the groove 16. The sliding action of the slider 13 drives the locking block 14 to move in and out of the groove 16. The locking block 14 is slidably connected to the inside of the fixed tube 12 through the slider 13. The fixed tube 12 is provided with a second spring 15 to provide a continuous return force to the slider 13. One end of the second spring 15 is fixedly connected to the side wall of the slider 13, and the other end of the second spring 15 is fixedly connected to the inside of the fixed tube 12. The second spring 15 ensures that the slider 13 and the locking block 14 can automatically reset after the external force is lost.

[0033] Working principle: When installing the reader / writer body 1, first insert the plug 11 connected to the bottom of the reader / writer body 1 into the interior of the mounting bracket 8. During the insertion process, the outer wall of the plug 11 will press against the locking block 14, causing it to move into the interior of the fixing tube 12, and causing the second spring 15 to deform under pressure. As the plug 11 continues to move downward, when the groove 16 moves between the locking blocks 14, the second spring 15 will lose pressure and push the slider 13 to reset, thereby locking the locking block 14 inside the groove 16, thus completing the connection between the reader / writer body 1 and the mounting bracket 8. Then, the mounting bracket 2 is inserted... Once the mounting is fixed, the reader body 1 can be installed. When it is necessary to change the tilt angle of the reader body 1, push the push block 9 to make the toothed plate 5 slide inside the sleeve 3, compressing the first spring 10 to deform it. At this time, the toothed plate 4 separates from the toothed plate 5. Then, by rotating the push block 9, the slide rod 6 is rotated, and the fixing frame 8 is deflected simultaneously, thereby changing the angle of the reader body 1. After the angle is adjusted, release the push block 9. At this time, the first spring 10 pushes the toothed plate 5 to reset, and the toothed plate 4 and the toothed plate 5 engage, thereby locking the adjusted angle.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
