Description

Technical Field

[0001] The utility model relates to the technical field of ultra-high frequency RFID handheld devices, in particular to an ultra-high frequency RFID handheld terminal electronic tag reader / writer. Background Art

[0002] An ultra-high frequency (UHF) RFID handheld terminal electronic tag reader / writer is a radio frequency identification (RFID) device that operates in the ultra-high frequency (UHF) band, typically between 840 and 960 MHz (standards vary slightly across the globe). It transmits energy through electromagnetic fields and uses electromagnetic wave reflection coupling to read the information stored in RFID tags. This contactless automatic identification technology not only improves operational efficiency but also greatly enhances convenience.

[0003] The patent, currently published with the announcement number CN218938968U, discloses an RFID handset with an integrated dual-frequency antenna device. The handset includes a handset body, a fixing bracket, and an antenna extension assembly. The handset body is in a gun-shaped structure with a gripping handle at the lower rear portion. The handset body and the antenna extension assembly are mounted and fixed to the lower front portion of the handset body. The antenna extension assembly is located in front of the gripping handle. The antenna extension assembly includes a housing, a high-frequency antenna assembly, and an ultra-high-frequency antenna assembly. The high-frequency antenna assembly and the ultra-high-frequency antenna assembly are arranged parallel to each other within the housing. The fixing bracket is removably mounted on top of the antenna extension assembly and can abut against the handset body. By attaching a relatively simple dual-frequency antenna extension module to the handset body, the versatility of the RFID handset with an integrated dual-frequency antenna device is effectively improved while taking into account the coupling properties of the two different frequency antennas without interference. This meets the high-frequency and ultra-high-frequency usage requirements of RFID devices.

[0004] However, in bright sunlight, especially when used outdoors, operators may have difficulty clearly viewing the camera's image. This increases operational difficulty and the risk of misoperation, potentially impacting the efficiency and accuracy of the RFID handheld. While bright sunlight primarily affects the camera, it can also indirectly affect the overall functionality of the RFID handheld. For example, if the camera is damaged or image quality degrades, the RFID handheld may perform poorly in scenarios requiring simultaneous camera and RFID recognition. Utility Model Content

The main improvement of the present invention is that by installing a detachable shielding mechanism on the handheld device body 1, the inclined folding plate 9 can block strong light, making it easier for staff to observe the display screen, and after the baffle 16 is connected to the shielding mechanism, it can also block strong light from above the handheld device body 1 camera to protect the camera. When not in use, the folding plate 9 and the baffle 16 can be disassembled. Figures 1 to 6 As shown, when the ultra-high frequency RFID handheld terminal electronic tag reader in the present invention is used in a strong light environment, the shielding mechanism is taken out from the equipment box, and the folding plate 9 is unfolded, and then the first support rod 7 is inserted into the first slide groove 4 on the first fixed block 2, and the second support rod 8 is inserted into the second slide groove 5 on the second fixed block 3. At the same time, the reinforcement component is taken out from the equipment box, and the first insertion rod 14 is inserted into the first hole 11 on the first support rod 7, and the second insertion rod 15 is inserted into the second hole 12 on the second support rod 8.

At this time, the annular block 17 on the first plug rod 14 and the second plug rod 15 is stuck in the annular groove 13 to fix the first plug rod 14 and the second plug rod 15. The reinforcement component can connect the first support rod 7 and the second support rod 8, and the baffle 16 is located above the camera to block strong light to reduce the exposure of strong light to the camera, thereby protecting the camera.

[0032] like Figure 4 As shown, the fixing assembly includes a threaded rod 18 threadedly connected to the threaded hole 6, and a turntable 19 is fixedly connected to the threaded rod 18. The output end of the threaded rod 18 is against the inner wall of the groove 10. The diameter of the turntable 19 is larger than the width of the first fixed block 2, and the side of the turntable 19 is frosted.

[0033] Specifically, by rotating the turntable 19 inward, the front end of the threaded rod 18 moves inward until the front end of the threaded rod 18 is in contact with the inner wall of the groove 10, thereby fixing the first support rod 7 and fixing the folding plate 9.
