Abstract

The utility model provides a RFID electronic tags reads ware, include: a housing; an inner core disposed within the housing; the magnetic coil is arranged at one end of the shell, and the inner core can slide and adjust along the radial direction of the shell; an iron rod passing through the inner core. The change of the reading distance of the RFID electronic tag reader is realized by adjusting the relative distance between the inner core and the magnetic coil.

Description

RFID electronic tag reader

Technical Field

The utility model relates to a RFID electronic tags reads the ware, especially relates to an adjustable RFID electronic tags who reads card distance reads ware.

Background

And the RFID electronic tag reader is called a long-distance RFID electronic tag reader. Data in an IC card can be read at a long distance and is generally used in an ETC system or the like. The reading range of the RFID tag reader is usually a relatively fixed value range, for example, about 8-10 m. If the IC card data needs to be read in different distance ranges, different RFID electronic tag readers need to be replaced.

A new RFID electronic tag reader needs to be designed, the card reading distance of the RFID electronic tag reader can be adjusted according to needs, and the whole RFID electronic tag reader does not need to be replaced. The RFID electronic tag reader is simple in structure and convenient to adjust.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a RFID electronic tags reads ware, its simple structure through adjusting inside device, can realize the adjustment of reading the distance on a large scale.

An RFID electronic tag reader comprising: a housing; an inner core disposed within the housing; the magnetic coil is arranged at one end of the shell, and the inner core can slide and adjust along the radial direction of the shell; an iron rod passing through the inner core.

The RFID electronic tag reader is characterized in that a contact block is arranged on the outer side of a shell and is in contact with an inner core.

The RFID electronic tag reader is characterized in that protective covers are arranged at two ends of a shell.

Because the inner core can radially slide relative to the shell, the reading range of the RFID electronic tag reader can be adjusted by adjusting the distance between the inner core and the magnetic coil.

Detailed Description

Fig. 1 is a schematic diagram of the overall structure of the RFID tag reader of the present invention. As shown in fig. 1, the RFID tag reader includes: the cross section of the shell 1 is square or circular. The inner core 2 is installed inside the outer shell 1. The outer side of the shell 1 is provided with a contact block 6, and the contact block 6 is provided with a contact 7. The inner core 2 is in contact with the contact block 6. A magnetic coil 3 is arranged at one end of the housing 1. The inner core 2 can slide along the radial direction of the shell 1, and the distance between the inner core 2 and the magnetic coil 3 is adjusted. As shown in fig. 3, which is a schematic structural diagram of the inner core 2, a through hole 8 is formed on the inner core 2 near the contact surface of the contact block 6. In fig. 1, an iron rod 5 passes through the through hole 8.

Fig. 2 is a schematic diagram of a housing of the RFID tag reader in this embodiment. In this embodiment, the two ends of the RFID tag reader housing 1 are provided with the protective covers 4 for preventing rainwater, dust and the like from entering the housing 1, thereby affecting the reading accuracy and the reading distance.

In this embodiment, the distance between the inner core 2 and the magnetic coil 3 is adjusted, and then the inner core 2 is fixed in the outer shell 1, so that the reading distance in a large range of about 2-10m can be realized. The reading distance can be adjusted according to requirements. Compared with the common RFID electronic tag reader, the reading distance can be adjusted only within a smaller range, for example, about 8-10 m. If the distance is adjusted to 2-4m, the RFID electronic tag reader needs to be replaced. The RFID electronic tag reader of the embodiment has the advantages of simpler structure, convenience in adjusting and reading distance and cost saving.

The protection of the present invention is not limited to the above embodiments. Variations and advantages that may occur to those skilled in the art may be incorporated into the invention without departing from the spirit and scope of the inventive concept, and the scope of the appended claims is intended to be protected.
