Radio Frequency (RF) is an abbreviation for Radio Frequency, which refers to an electromagnetic Frequency that can radiate into space, ranging from 300KHz to 300 GHz. The short term Radio Frequency (RF) is radio frequency current, which is a short term for high frequency Alternating Current (AC) variable electromagnetic wave. Alternating current that changes less than 1000 times per second is called low frequency current, and alternating current that changes more than 10000 times per second is called high frequency current, and radio frequency is such a high frequency current. High frequency (greater than 10K); the radio frequency (300K-300G) is a higher frequency band of high frequency; the microwave band (300M-300G) is again the higher frequency band of radio frequencies. In the theory of electronics, current flows through a conductor, and a magnetic field is formed around the conductor; an alternating current passes through a conductor, around which an alternating electromagnetic field, called an electromagnetic wave, is formed. When the frequency of the electromagnetic waves is lower than 100kHz, the electromagnetic waves can be absorbed by the earth surface and cannot form effective transmission, but when the frequency of the electromagnetic waves is higher than 100kHz, the electromagnetic waves can be transmitted in the air and reflected by an ionosphere at the outer edge of the atmosphere to form long-distance transmission capability, and the high-frequency electromagnetic waves with the long-distance transmission capability are called radio frequency; radio frequency technology is widely used in the field of wireless communications.

An antenna is a transducer that converts a guided wave propagating on a transmission line into an electromagnetic wave propagating in an unbounded medium (usually free space) or vice versa. A component for transmitting or receiving electromagnetic waves in a radio device. Engineering systems such as radio communication, broadcasting, television, radar, navigation, electronic countermeasure, remote sensing, radio astronomy and the like all use electromagnetic waves to transmit information and work by depending on antennas. In addition, in transferring energy with electromagnetic waves, non-signal energy radiation also requires antennas. The antennas are generally reciprocal in that the same pair of antennas can be used as both transmit and receive antennas. The same antenna is the same as the basic characteristic parameter for transmission or reception. At present, the antenna is more and more widely applied, the anti-interference requirement is more and more strict, and the design types are diversified. Such as a radio frequency antenna used in an RFID electronic tag or label, to be widely used in the field of logistics. It can store data related to merchandise, credit cards, access cards, and vehicle control in RF. The radio frequency antenna circuit is matched with a radio frequency IC chip in the RFID electronic seal, and an RFID reader matched with the radio frequency antenna is used for reading information in the radio frequency IC chip. The RFID electronic seal can also be applied to the locking device, and when the locking device is in a locking state, the radio frequency IC chip can be read. The ideal antenna does not consider the feeding part, but in order to extract signals, the extracted point is called the feeding part, the english is expressed by feedpoint, the field distribution of the antenna is generally influenced by the addition of the feeding part, and the selection of the point is also exquisite.

When the RFID electronic tag is manufactured, the surface with the antenna and the radio frequency IC chip is directly coated with the adhesive, so that the RFID electronic tag can be attached to commodities, objects or parts for use. When the RFID reader transmits a signal to the RFID electronic tag for receiving, the radio frequency IC chip is started, the data stored in the radio frequency IC chip is transmitted to the RFID reader through the antenna for receiving, and the RFID reader can read the return signal of the RFID electronic tag. Since the application of the conventional typical RFID tag is limited by the influence of external environmental factors, for example, signals read by the RFID reader are easily interfered and diffracted in water, liquid or high humidity air, which results in a high error rate of reading signals, and if the RFID tag is attached to an object with a metal surface, the data reading error rate is high or the RFID tag cannot be read.

When the first limiting plate is inserted into the limiting groove, the first blocking piece is gradually inserted into the first fixing groove, and the first blocking piece and the third blocking piece are stacked up and down.

Further, the engaging structure 43 further includes a fourth blocking member (not labeled), the fourth blocking member is located on a side of the first limiting plate away from the third blocking member, the protruding edge (not labeled), the first limiting plate and the fourth blocking member enclose a second fixing groove (not labeled), an accommodating space is formed between the third blocking member and the fourth blocking member, and the third blocking member and the first limiting plate enclose a third fixing groove (not labeled);

wherein, when first limiting plate holds and inserts the spacing groove, the in-process that first stopper inserted first fixed slot, the second stops the piece and inserts the second fixed slot gradually, and the third fixed slot is inserted gradually to the second limiting plate, and the second stops and stops the piece range upon range of setting from top to bottom with the fourth.

The engaging structure 43 has two conductive parts respectively located on the first lock body 41 and the second lock body 42, wherein when the first lock body 41 is separated from the second lock body 42, the first circuit and the second circuit are disconnected, and when the first lock body 41 is engaged with the second lock body 42, the first circuit and the second circuit are disconnected.

The utility model also provides a device with a locking function, which comprises the locking seal and the locking seal device 100, wherein the locking seal device 100 is used for locking and unlocking the seal.

In summary, in the technical solution of this embodiment, the locking device 100 connects the rf antenna board 10 and the circuits in the first lock body 41 and the second lock body 42 through the barb conducting element, so that the rf IC chip 2 located therein can be identified and read by an external read-write device matched with the rf antenna circuit, thereby detecting whether the locking device 100 is in the locking state.

The above description is only a preferred embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications and equivalents of the technical solutions of the present invention, which are made by using the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
