the first circuit of the lock seal comprises n disconnected positions, each disconnected position is connected with one conductive locking elastic moving piece 3 in a separable concave-convex clamping mode to be closed or disconnected, the tail end of one conductive locking elastic moving piece 3 is electrically connected with one end of one disconnected position, the head end of the conductive locking elastic moving piece is connected with the other end of the disconnected position in a separable concave-convex clamping mode to achieve the on-off or the off-off of the radio frequency circuit, the n disconnected positions are connected in series in a head-to-tail mode to achieve the locking detection of the n disconnected positions, when each disconnected position is closed, the first circuit of the lock seal and the radio frequency antenna form a complete radio frequency circuit to be closed and conducted, and therefore the radio frequency IC chip 2 can be read by external reading equipment matched with;

under the condition that the lock facing slip 5 is locked in place, the lock facing slip 5 is locked after being clamped by the position of the conductive locking elastic moving piece 3, and then a lock conducting state is formed.

The locking device adopts RFID Radio Frequency technology, and Radio Frequency (RF) is an abbreviation of Radio Frequency and represents electromagnetic Frequency capable of radiating to space, and the Frequency range is 300 KHz-300 GHz. Radio frequency technology is widely used in the field of wireless communications. 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, electricity is saved, and particularly for some places where electricity is strictly controlled, such as bank storage, warehouse and the like, in order to prevent fire, the passive RFID radio frequency technology is adopted. 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 rf IC chip or the circuit board rf IC chip electrically connected to the rf antenna circuit are matched with each other, and the following description is omitted.

In this embodiment, lock facing slip 5 is connected with the cooperation of lock body 4 and makes the lock seal device be in the lock state of sealing, and lock facing slip 5 makes the lock seal device be in the unblock state with the separation of lock body 4, because of electrically conductive locking elastic movement piece 3 has the elastic function, contacts with the circuit access end in the lock facing slip 5 or breaks off and realizes that lock seal circuit or other circuits switch on and break off, and other circuits can be radio frequency circuit, or non-radio frequency circuit. Referring to fig. 3, the conductive locking elastic moving member 3 has an elastic function, because one end of the conductive locking elastic moving member 3, which is used for being connected with an external connecting member, is connected with the mounting member through an elastic structure, which may be a spring, such as a compression spring 8. It will be appreciated that the conductive locking resilient movement 3 may itself have a resilient function, such as a spring tab or the like.

In the process that the locking device forms a locking state, one end of the locking seal 5 slides forwards along and presses the stressed inclined plane 31 of the at least two conductive locking elastic moving parts 3 or the other two ends of the two conductive locking elastic moving parts 3 to the position where the first circuit of the locking seal is electrically connected with the first connecting circuit and the second connecting circuit. In the process, the conductive locking elastic moving part 3 is bounced under the oblique acting force applied by the locking seal 5, so that the conductive locking elastic moving part 3 has elastic potential energy or the elastic potential energy is increased; when the locking seal 5 is separated from the conductive locking elastic moving part 3, the oblique acting force is removed to enable the conductive locking elastic moving part 3 to rebound to the original position under the action of elastic potential energy or rebound to an object which resists the rebound towards the original position, if a concave groove is formed at the part where the locking seal 5 and the conductive locking elastic moving part 3 slide relatively, the conductive locking elastic moving part 3 and the sliding end of the part further rebound, and if the groove is a through hole, the end can penetrate through the through hole to the original position under the action of the elastic force. The relative movement between the locking seal 5 and the conductive locking elastic moving part 3 can be a linear movement or a curvilinear movement, such as an S-shaped curvilinear movement.

The oblique acting force is acting on the stressed inclined surface 31 of the conductive locking elastic moving element 3, so that the conductive locking elastic moving element can be bounced relative to the original position. After the conductive locking elastic moving part 3 bounces, the lock seal 5 can slide forward along the stress inclined plane 31, and after the conductive locking elastic moving part slides over the stress inclined plane 31, one end or more than one end of the conductive locking elastic moving part 3 supports the surface of the lock seal 5. The front of the insertion end of the lock facing slip 5 is also an inclined plane, so that the lock facing slip 5 can conveniently slide into the insertion space of the lock sealing device, and the resistance is reduced.

Wherein the type of break comprises a break between the first circuit of the lock tag and the first connection circuit, a break between the first circuit of the lock tag and the second connection circuit, a break in the first circuit of the lock tag; the former two enable disengagement of the lock tag 5 from the lock body or conductive locking resilient moving member 3.

For example, when the number of the disconnected positions is three, at least three conductive locking elastic moving members 3 are provided, and when the locking device is in an unlocking state, all three disconnected positions are disconnected, wherein the tail end of one conductive locking elastic moving member 3 is electrically connected with the first connecting circuit, the head end of the conductive locking elastic moving member is in a free state or abuts against/supports against the lock body, the tail end of the other conductive locking elastic moving member 3 is electrically connected with the second connecting circuit, the head end of the other conductive locking elastic moving member 3 is electrically connected with the first circuit of the locking seal tag, the head end of the other conductive locking elastic moving member 3 is in a free state or abuts against/supports against the lock body, and when the locking device is in a locking state, the head ends of the three conductive locking elastic moving members 3 all abut against the first circuit of the locking seal tag to be electrically connected, so that the three disconnected positions are electrically connected and conducted;

When each disconnected position is in a conducting and stable state, the lock seal 5 is locked in place, and the lock seal 5 is locked after being clamped by the position of the conductive locking elastic moving piece 3. When the head end of the conductive locking elastic moving piece 3 is connected with the other end of the disconnected part in a separable concave-convex clamping manner, the radio frequency circuit is switched on or switched off, namely, the head end of the conductive locking elastic moving piece 3 is disconnected with the other end of the disconnected part, namely, the concave-convex structures of the clamping position are separated, the radio frequency circuit is switched off, and when the head end of the conductive locking elastic moving piece 3 is connected with the other end of the disconnected part, namely, the concave-convex structures of the clamping position are connected, the radio frequency circuit is switched on.
