Description

Technical Field

[0001] The utility model belongs to the technical field of RFID electronic tags, and particularly relates to a protective RFID tag. Background Art

[0002] Radio Frequency Identification (RFID) is a type of automatic identification technology that uses radio frequency to conduct non-contact two-way data communication and read and write recording media, thereby achieving the purpose of identifying targets and exchanging data. It is considered to be one of the most promising information technologies in the 21st century. Its principle is non-contact data communication between readers and tags to achieve the purpose of identifying targets. RFID tags are a type of radio frequency identification product and technology that uses radio signals to identify specific targets and read and write related data without the need for mechanical or optical contact between the identification system and the specific target.

[0003] RFID electronic tags are widely used in industrial production. The RFID electronic tags currently on the market are not durable. During use, they are easily damaged by the external environment, have loose connections, and are easily broken by external contact, which affects their service life and the reception of external signals, and is not conducive to long-term use by users. In addition, when the RFID tag is squeezed by foreign objects, its internal chip may be damaged and the coil may also break, causing the tag to be unable to be used normally.

[0004] Therefore, this solution proposes a protective RFID tag to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a protective RFID tag, which solves the technical problem of how to protect and fix the RFID tag, so that the connection is firm and not easily broken by accidental contact from the outside, which is conducive to long-term use.

[0006] A protective RFID tag comprises an RFID tag, a positioning bolt passing through the RFID tag, a fixing bar connected to the positioning bolt, and a protective structure in contact with the RFID tag and the fixing bar, wherein two protective structures respectively cover both ends of the positioning bolt;

[0007] The fixing strip is positioned and connected to the industrial equipment or mechanical structure through a fixing plate.

[0008] The protective structure includes a protective cover with one side open and the other side closed, and a closing cover. One end of the closing cover is snap-connected to the open side of the protective cover, and the positioning bolt passes through the closed side of the protective cover.

[0009] The RFID tag is in a rectangular shape, and two threaded holes are respectively provided near its two ends, and the positioning bolt passes through the two threaded holes.

[0010] The RFID tag includes a chip, an antenna and a PET material, wherein the chip and the antenna are enclosed inside the PET material.

[0011] The outer side of the PET material is provided with any one of a QR code, a unit name, an asset category and an asset number, or at least two of them.

[0012] The fixing plate is in the shape of a rectangular sheet, and is provided with positioning holes near both ends thereof. Fixing bolts are passed through the positioning holes, and the fixing bolts are connected to the industrial equipment or the mechanical structure.

[0013] The fixing plate is bonded and fixed to the industrial equipment or mechanical structure.

[0014] The fixing plate and the protective structure are both made of metal.

[0015] The fixing bar is provided with a threaded hole 1, and the positioning bolt passes through the threaded hole 1.

[0016] The utility model achieves the following beneficial effects:

[0017] (1) Fix the RFID tag with a metal protective cover and a closing cover. The metal protective cover and the closing cover can enlarge the contact surface, so that the antenna can improve the efficiency of receiving signals;

[0018] (2) The protective cover and the closing cover are fixed by bolts, which can achieve explosion-proof and disassembly-proof effects;

[0019] (3) Since the antenna and chip in the original tag are wrapped in a PET material shell, which has insulating properties, the use of a metal protective cover, a closing cover, and a fixing plate can improve the extensibility of the antenna in the tag. BRIEF DESCRIPTION OF THE DRAWINGS
