Description

Technical Field

[0001] The utility model relates to the field technology of devices for radio frequency identification readers and writers, in particular to an antenna fastening device for radio frequency identification readers and writers. Background Art

[0002] Radio frequency identification (RFID) is a contactless automatic identification technology that uses radio frequency signals to automatically identify target objects and obtain relevant data. An RFID system consists of an electronic tag and a reader / writer. The electronic tag consists of a coupling element and a chip. Each electronic tag has a unique electronic code, which is attached to an object to identify it. The reader / writer transmits and receives RF signals to and from the electronic tag via an antenna to read and identify the information stored in the tag, thereby automatically identifying the object. Existing antenna fastening devices for RFID readers / writers do not use an adjustment component to adjust the position of the antenna body, making it difficult to meet requirements for antenna body movement. They do not use fasteners to secure the antenna body, making it difficult to meet requirements for fastening and installation. Furthermore, the adjustment member is not rotatably positioned between the connector and the upper connector, making it difficult to rotate the adjustment member. Therefore, in response to this situation, there is an urgent need to develop an antenna fastening device for RFID readers / writers that meets practical needs. Utility Model Content
