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.

The locking device adopts the RFID radio frequency technology, the RFID radio frequency technology comprises an active RFID radio frequency technology and a passive RFID radio frequency technology, the passive RFID radio frequency technology can be adopted in the embodiment, the electricity is saved, and the passive RFID radio frequency technology is adopted for preventing fire particularly for some places where electricity is strictly controlled, such as bank storage, warehouse and the like. Of course, in some embodiments, active RFID radio frequency technology may also be used, which can increase signal transmission distance, etc. In the present invention, the circuit of the rf antenna 1 and the rf IC chip of the rf connection or the rf IC chip of the circuit board are all matched with each other, and will not be described below.

The number of the radio frequency circuits arranged in the first radio frequency conducting piece 2 is one, for example, the number of the first radio frequency circuits can be two, or more than two, for example, 3, 4, 5, 6, 7, 8, etc.; the number of the rf circuits in the second rf conduction element 3 is one, for example, the number of the second rf circuits may also be two, or more than two, for example, 3, 4, 5, 6, 7, 8, etc.

The first radio frequency conducting piece 2 and the second radio frequency conducting piece 3 can be circuit boards, RFID electronic seals, parts/structures with various shapes of radio frequency circuits and the like, for example, the first radio frequency conducting piece 2 is a circuit board, the second radio frequency conducting piece 3 is an RFID electronic seal, the second radio frequency conducting piece 3 realizes the disconnection of the first radio frequency circuit and the conduction of the second radio frequency circuit by being inserted between the first radio frequency conducting piece 2 and the conductive clamping elastic moving piece 4, and further realizes the process that the locking device is converted from an unlocking/unlocking state into locking state, and finally realizes the locking state.

The relative movement between the second rf conducting member 3 and the conductive clamping elastic moving member 4 can be a linear movement or a curved movement, such as an S-shaped curved movement.

In the present invention, 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.

It can store data related to merchandise, credit cards, access cards, and vehicle control in RF. The radio frequency antenna 1 is matched with a radio frequency IC chip in the RFID electronic seal, and an RFID reader matched with the radio frequency antenna 1 reads 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. In the invention, the conducting connection end of the conductive clamping elastic moving piece 4 is directly connected with the feed part of the radio frequency antenna 1 or the circuit of the radio frequency antenna 1.

When the circuit is connected, the circuit can work by generating current, the circuit can work by an external power supply, and the circuit can work by generating current by an RFID technology. Different circuit functions can be realized according to different communicated electronic elements. A continuously connected segment of the circuit has two access points between which all the electronic components are connected. The access point of the circuit may also be referred to as a connection point or an access end (referred to as an access end in the present invention), the access end of the circuit refers to a point/end capable of communicating with the circuit, the access end is attached to a physical mechanical component, the component may be a conductive sheet, a conductive block, a conductive plate, or the like, or may be an end of a wire, the conductive sheet, the conductive block, the conductive plate, and a portion of the wire exposed outside form a conductive region (also referred to as a conductive cell), the conductive region is formed by a plurality of conductive contacts, and any one of the conductive contacts connected with the conductive region is communicated with its corresponding circuit.
