Description

Technical Field

[0001] The utility model relates to the technical field of RFID readers and writers, in particular to a low-power module RFID reader and writer. Background Art

[0002] An RFID reader is an advanced automatic identification device that uses radio frequencies to communicate contactlessly with RFID tags, reading and writing data. This technology, characterized by its efficiency, accuracy, durability, and high security, has been widely used in numerous fields. The operating principle of an RFID reader is based on the transmission and reception of radio frequency signals. When the reader emits a radio frequency signal of a certain frequency, nearby RFID tags receive the signal and become activated. They then transmit the stored data to the reader via a return signal. The reader decodes and processes the data, enabling identification and management of the tag information. Low-power RFID readers typically consume less than 1W, meaning they can be powered by smaller batteries, reducing the size and weight of the device and extending its lifespan.

[0003] The existing Chinese patent with announcement number CN215769737U discloses an efficient handheld low-power RFID card reader device, including a card reader body and a handheld handle, the top of the handheld handle is installed on the left side of the bottom end of the card reader body; it also includes a storage box, a positioning slide rail, a positioning slide groove, a first limit seat, a first bearing, a support shaft, a limit pin, a connecting shaft and an adjustment mechanism. The top of the storage box is installed at the bottom end of the card reader body, the positioning slide rails are symmetrically installed on the front and rear walls of the storage box cavity, the positioning slide grooves are respectively slidably connected with the positioning slide rails, a slot hole is provided at the left end of the positioning slide groove, the support shafts are respectively coaxially connected to the first bearing, the limit pins are respectively slidably installed inside the through hole of the support shaft, the adjustment mechanism is installed inside the working cavity of the handheld handle, and the output ends of the adjustment mechanism are respectively connected with the connecting shafts.

[0004] Although the above solution can adjust the grip, the entire grip is still connected to the RFID card reader body. Operators often need to use special tools to disassemble it and may need to follow a series of complicated steps to unlock the fixing device. This process is not only time-consuming and labor-intensive, but may also damage other components of the card reader due to improper operation, making the replacement of the grip inconvenient. Therefore, it does not meet existing needs. In response to this, we have proposed a low-power modular RFID reader. Utility Model Content

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. The utility model provides a mounting base at the lower end of the RFID reader body. When the handle is disassembled, it is only necessary to turn the knob. The meshing transmission of the bevel gear can make the threaded rod rotate synchronously. The threaded rod will drive the moving block to move the limit block out of the limit groove, thereby quickly releasing the fixation of the handle and making it convenient to disassemble and assemble the handle. Once the handle is damaged, the replacement operation time can be significantly shortened, thereby improving the maintenance efficiency of the equipment.

[0017] 2. The utility model provides storage seats on both sides of the RFID reader body. When the RFID reader body is not in use for storage, the operator can separate the handle and pull the connecting plate upward to move the baffle up, and then place the handle in the storage seats on both sides and fix them with magnetic iron sheets. After loosening the connecting plate, the handle can be stored inside the storage seat, which can avoid the handle taking up storage space, is easy to carry, and has good practicality.

[0018] 3. The utility model has a magnetic iron sheet adhered and fixed on the inner side of the handle. When the RFID reader is in use, the two handles can be fixed by the magnetic iron sheet, making it easy to grasp. When storing, the two handles can be separated, making storage more convenient. At the same time, due to the modular separation design, when one of the handles is damaged, there is no need to replace both handles. Only one handle needs to be replaced, saving maintenance costs.

The front end of the handle 2 located at one end inside the card slot 10 is provided with a limit slot 11, and the limit slot 11 is adapted to the end of the limit block 9 located inside the card slot 10;

[0028] It also includes a stretching cavity 18, which is opened on both sides of the storage seat 4. Sliders 20 are slidably arranged inside the stretching cavity 18, and pull rods 19 are adhered and fixed to the upper ends of the sliders 20. One end of the pull rods 19 passes through and extends to the outside of the stretching cavity 18, and the pull rods 19 slide in cooperation with the stretching cavity 18.

[0029] When in use, the two handles 2 are initially fixed by the magnetic iron sheet 13 and inserted into the card slot 10, the docking rod 24 is docked and positioned with the docking hole 12, and then the knob 17 is rotated, and the threaded rod 6 is driven to rotate through the meshing transmission of the bevel gear 15, so that the moving block 8 moves in a straight line along the guide rod 7, pushing the limit block 9 into the limit slot 11 to fix the handle 2. When not in use, the handle 2 can be disassembled by reversing the operation, and the connecting plate 22 can be pulled, and the elastic force of the reset spring 21 can be used to drive the baffle 23 to move up, open the storage seat 4, and store the handle therein, saving space and making it easy to carry.

The overall operation is simple and convenient, and it is convenient for daily operation. When the RFID reader body 1 is not in use, the above steps can be installed to disassemble the handle 2, and the two handles 2 can be separated. Then, the connecting plate 22 is pulled, and the connecting plate 22 will drive the pull rod 19 to move upward. The connecting plate 22 will drive the slider 20 to move upward in the stretching cavity 18, and the reset spring 21 will be compressed. At this time, the connecting plate 22 will drive the baffle 23 to move upward synchronously, so that the interior of the storage seat 4 is opened, so that the handle 2 can be stored inside the storage seat 4, which can avoid the handle 2 occupying storage space, easy to carry, and practical.
