Description

[0002] With the development of science and technology, RFID technology has been widely used, such as in locking devices. When existing bags, bags, boxes, cabinets, etc. contain confidential items and cash and need to be locked, they usually use padlocks, electronic password locks, etc. In the above-mentioned prior art, each padlock needs to be equipped with a dedicated key to unlock it. In addition, each electronic password lock also requires a unique password key, which is not convenient for unified management. In addition, the two can neither send and receive radio frequency signals nor perform remote inspection of the lock's locking state. They can only be checked by macroscopic observation or manual inspection to see whether the padlock or smart lock is in a locked state, which is more troublesome to operate. Therefore, batches of bags, boxes, cabinets, etc. cannot be checked at the same time, and it takes a long time to check them one by one, which increases the operating cost. Therefore, there is an urgent need for a locking device that uses a batch wireless detection method to inspect the locking state. Summary of the invention

[0056] Please refer to Figures 1 to 3 The present invention provides a locking device. In a first embodiment of the present invention, the locking device includes a radio frequency antenna 1, a radio frequency IC chip 2, a conductive locking elastic moving part 3, a lock body 4 and a lock seal 5. The two ends of the radio frequency antenna 1 are electrically connected to a first connection circuit (not marked) and a second connection circuit (not marked), respectively; at least one conductive locking elastic moving part 3 is electrically connected to the first connection circuit, and at least another conductive locking elastic moving part 3 is electrically connected to the second connection circuit. The conductive locking elastic moving part 3 has an elastic function and is configured with a force-bearing inclined surface 31 at one end. When the force-bearing inclined surface 31 is subjected to an oblique force, the conductive locking elastic moving part 3 can bounce up, and when the oblique force is withdrawn, the conductive locking elastic moving part 3 can bounce up. The movable part 3 can rebound toward the original position; the lock body 4 is provided with a radio frequency antenna 1 and a conductive locking elastic movable part 3; the lock seal 5 is a component that plays a locking and sealing role, and is connected with the lock body 4 and the conductive locking elastic movable part 3 to form a locked state of the locking and sealing device; at least one circuit is provided in the lock seal 5, and one of the circuits is named the lock seal first circuit (not marked); when the locking and sealing device is in the locked state, the lock seal 5 and the at least two conductive locking elastic movable parts 3 are locked and connected in a concave-convex clamping position, so as to simultaneously realize the electrical connection between the lock seal first circuit and the first connection circuit and the second connection circuit and the electrical connection of the detection signal; the radio frequency IC chip 2 is arranged in the complete radio frequency circuit formed by the lock seal first circuit and the radio frequency antenna;

[0057] Wherein, the first circuit of the lock seal includes n disconnected places, each disconnected place is connected to a conductive locking elastic moving part 3 by a detachable concave-convex snap-fit ​​connection to be closed or disconnected, the tail end of a conductive locking elastic moving part 3 is electrically connected to one end of a disconnected place, and its head end is connected to the other end of the disconnected place by a detachable concave-convex snap-fit ​​connection to realize the conduction, closure or disconnection of the radio frequency circuit, so that the head and tail are connected in series to realize the locking detection of n disconnected places, and when each disconnected place is closed, the first circuit of the lock seal and the radio frequency antenna form a complete radio frequency circuit closure and conduction, so that the radio frequency IC chip 2 can be read by an external reading device matched therewith, n≥2;

[0058] When the lock seal 5 is locked in place, the lock seal 5 is locked by the conductive locking elastic moving part 3 to form a lock-sealed conductive state.

[0059] The locking device of the present invention adopts RFID radio frequency technology. Radio frequency (RF) is the abbreviation of Radio Frequency, which means the electromagnetic frequency that can be radiated into space, and the frequency range is between 300KHz and 300GHz. Radio frequency technology is widely used in the field of wireless communication. RFID radio frequency technology includes active RFID radio frequency technology and passive RFID radio frequency technology. In this embodiment, passive RFID radio frequency technology can be used to save electricity, especially for some places where electricity is strictly controlled, such as bank warehouses, warehouses, etc., in order to prevent fire, passive RFID radio frequency technology is used. Of course, in some embodiments, active RFID radio frequency technology can also be used to increase the signal transmission distance, etc. In the present invention, the radio frequency antenna circuit and the radio frequency IC chip or circuit board radio frequency IC chip electrically connected to the radio frequency antenna are matched with each other, and will not be explained one by one below.

[0060] In this embodiment, the lock seal 5 is connected with the lock body 4 so that the lock seal device is in a locked state, and the lock seal 5 is separated from the lock body 4 so that the lock seal device is in an unlocked state. Because the conductive locking elastic moving part 3 has an elastic function, it contacts or disconnects with the circuit access end in the lock seal 5 to realize the connection and disconnection of the lock seal circuit or other circuits. The other circuits can be radio frequency circuits or non-radio frequency circuits. Please refer to Figure 3 The conductive locking elastic moving part 3 has an elastic function because one end of the conductive locking elastic moving part 3 used for connecting with the external connecting part is connected to the mounting part through an elastic structure, and the elastic structure can be a spring, such as a compression spring 8. It can be understood that the conductive locking elastic moving part 3 can have an elastic function itself, such as a spring.

[0061] During the process of the locking device forming a locked state, one end of the lock seal 5 slides forward along and presses the force-bearing inclined surfaces 31 of 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 lock seal is electrically connected with the first connection circuit and the second connection circuit. In this process, the conductive locking elastic moving part 3 is bounced up by the oblique force applied by the lock seal 5, so that the conductive locking elastic moving part 3 has elastic potential energy or increases elastic potential energy; when the lock seal 5 is separated from the conductive locking elastic moving part 3, the oblique force is withdrawn, so that the conductive locking elastic moving part 3 rebounds back to its original position or rebounds toward its original position to resist the object that blocks the rebound, such as a concave groove appears at the relative sliding position of the lock seal 5 and the conductive locking elastic moving part 3, and the conductive locking elastic moving part 3 and the sliding end of the part further rebound. If the groove is a through hole, the end will pass through the through hole to the original position under the action of the elastic force. The relative movement between the lock seal 5 and the conductive locking elastic moving part 3 can be a linear movement or a curved movement, such as an S-shaped curved movement.

[0062] The oblique force refers to the force acting on the force-bearing inclined surface 31 of the conductive locking elastic moving part 3, which enables it to bounce up relative to the original position. After the conductive locking elastic moving part 3 bounces up, the lock seal 5 can slide forward along the force-bearing inclined surface 31. After sliding over the force-bearing inclined surface 31, one end or more than one end of the conductive locking elastic moving part 3 presses against the surface of the lock seal 5. The front of the insertion end of the lock seal 5 is also an inclined surface, which facilitates the lock seal 5 to slide into the insertion space of the locking device and reduces resistance.

[0063] Among them, the types of disconnection include a disconnection between the first circuit of the lock seal and the first connecting circuit, a disconnection between the first circuit of the lock seal and the second connecting circuit, and a disconnection within the first circuit of the lock seal; the first two enable the lock seal 5 to be separated from the lock body or the conductive locking elastic moving part 3.

[0064] The number of disconnections is any value greater than or equal to two, such as 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, etc. Please refer to Figure 4 For example, when there are two disconnected positions, there are at least two conductive locking elastic moving parts 3. When the locking device is in an unlocked state, the two disconnected positions are disconnected, the tail end of one of the conductive locking elastic moving parts 3 is electrically connected to the first connection circuit, and the head end is in a free state or abuts / holds the lock body, the tail end of the other conductive locking elastic moving part 3 is electrically connected to the second connection circuit, and the head end is in a free state or abuts / holds the lock body, when the locking device is in a locked state, the head end of one conductive locking elastic moving part 3 abuts against the first circuit access end of the touch lock seal and is electrically connected, and the head end of the other conductive locking elastic moving part 3 abuts against the other access end of the first circuit of the touch lock seal and is electrically connected, so that the two disconnected positions are electrically connected and conductive. For another example, when there are three disconnected positions, there are at least three conductive locking elastic moving parts 3, and when the locking and sealing device is in the unlocked state, the three disconnected positions are all disconnected, the tail end of one of the conductive locking elastic moving parts 3 is electrically connected to the first connection circuit, and the head end is in a free state or abuts / holds the lock body, the tail end of another conductive locking elastic moving part 3 is electrically connected to the second connection circuit, and the head end is in a free state or abuts / holds the lock body, and the tail end of the remaining conductive locking elastic moving part 3 is electrically connected to the first circuit of the lock seal, and the head end is in a free state or abuts / holds the lock body, and when the locking and sealing device is in the locked state, the head ends of the three conductive locking elastic moving parts 3 all abut and touch the first circuit of the lock seal and are electrically connected, so that the three disconnected positions are electrically connected and conductive;

[0065] Please refer to it again Figure 1For another example, when there are four disconnected locations, there are at least four conductive locking elastic moving parts 3, and when the locking device is in the unlocked state, the four disconnected locations are all disconnected, the tail end of one of the conductive locking elastic moving parts 3 is electrically connected to the first connection circuit, and the head end is in a free state or abuts / holds the lock body, the tail end of another conductive locking elastic moving part 3 is electrically connected to the second connection circuit, and the head end is in a free state or abuts / holds the lock body, the tail ends of the remaining two conductive locking elastic moving parts 3 are electrically connected to the first circuit of the lock seal, and the head ends are in a free state or abuts / holds the lock body, and when the locking device is in the locked state, the head ends of the four conductive locking elastic moving parts 3 all abut and touch the first circuit of the lock seal and are electrically connected, so that the four disconnected locations are electrically connected and conductive. Please refer to Figure 2 Schematic diagram of the sealing device in the sealing state; n disconnections can be connected in series with the first circuit of the seal, or in parallel with the first circuit of the seal, such as one disconnection connected in parallel with two disconnections, two disconnections connected in parallel with two disconnections, etc. In some other embodiments, a conductive locking elastic moving part 3 at the disconnection between the first connection circuit and the first circuit of the seal, the tail end of the conductive locking elastic moving part 3 is electrically connected to the first circuit of the seal, and the head end thereof touches the first connection circuit of the seal through a detachable contact. The second connection circuit is the same, and is not limited one by one again.

[0066] Among them, the lock seal 5 is locked and connected with at least two conductive locking elastic moving parts 3 at the concave and convex clamping positions, and the two can be separated and locked at the concave and convex clamping positions, and the convex part automatically penetrates into the concave part through the elastic function of the conductive locking elastic moving part 3, and the convex end of the conductive locking elastic moving part 3 can be inserted into the concave end of the lock seal 5 to form a clamping position and lock the connection, or the concave end of the conductive locking elastic moving part 3 and the convex end of the lock seal 5 can form a clamping position and lock the connection. When each disconnection is in a conductive and stable state, the lock seal 5 is locked in place, and the lock seal 5 is locked after being engaged by the conductive locking elastic moving part 3. When the head end of the conductive locking elastic moving part 3 is connected to the other end of the disconnection position by a detachable concave-convex snap connection, the radio frequency circuit is turned on or off, that is, the head end of the conductive locking elastic moving part 3 is disconnected from the other end of the disconnection position, that is, the concave-convex structures of the two in the snap position are separated, and the radio frequency circuit is disconnected. When the head end of the conductive locking elastic moving part 3 is connected to the other end of the disconnection position, that is, the concave-convex structures of the two in the snap position are connected, and the radio frequency circuit is turned on. The detachable concave-convex snap connection ensures that the conductive locking elastic moving part 3 is connected and disconnected with the circuit in the lock seal 5, and realizes the conversion of the lock state and the unlock state of the lock sealing device, which is convenient to use. The concave-convex snap connection makes the conductive locking elastic moving part 3 and the lock seal 5 connected stably, limits the relative movement of the two to lock, and further ensures the stability of the lock state. At the same time, the vibration of the concave-convex snap connection can also be felt by hand, which improves the user's hand feeling and is convenient for users to use. The conductive locking elastic moving part 3 plays the role of conducting electricity and connecting the circuit. At the same time, the conductive locking elastic moving part 3 can transmit electrical signals when reading the radio frequency IC chip 2. In addition, the conductive locking elastic moving part 3 has an elastic function to support the lock seal 5 so that the lock seal 5 is tightly connected to the lock body, thereby realizing the locking state of the locking device. In the present invention, at least one conductive locking elastic moving part 3 is used to control the connection between different circuits, so that the radio frequency antenna 1 and the radio frequency IC chip 2 form multiple combinations of conduction to realize the functions of different circuits. Simplify the structure of the locking device.

[0067] In the technical solution of the present invention, one end of the lock seal 5 slides forward along and presses the force-bearing inclined surfaces 31 of at least two conductive locking elastic moving parts 3 until each disconnection is in a conductive state, so that the radio frequency IC chip 2 can be read by an external reading device matched therewith through wireless transmission, and it is known that the lock seal device is in a locked state. When the external reading device cannot read the radio frequency IC chip 2, it can be determined that the lock seal device is not in a locked state. By detecting whether the lock seal device is in a locked state, it can be determined whether the bag, bag, box, box, cabinet, etc. equipped with the lock seal device contains confidential objects, and the lock seal state can be inspected by a batch wireless detection method, that is, it can be inspected at the same time, which is convenient for batch inventory, simple to operate, and widely used.

[0068] It can be understood that the lock seal 5 also includes a lock seal second circuit. When the lock seal device is in a locked state or an unlocked state, the lock seal second circuit is connected to the circuit in the lock body 4 through at least one conductive locking elastic moving part 3. For example, when the lock seal 5 slides to a preset distance, one end of the conductive locking elastic moving part 3 supports or touches the access end of the lock seal second circuit, so that the lock seal second circuit forms a closed loop. The preset distance can be the position in the locked state or other positions. The circuit in the lock seal 5 can be one, two, or more than two. Two circuits can be turned on at the same time, or one, or more than two. If the lock seal 5 also includes a lock seal third circuit and a lock seal fourth circuit, the present invention does not limit them one by one, and the number and type of the lock seal circuit, the time of conduction, and the position of conduction are designed according to the use needs. Among them, the lock seal 5 can include one radio frequency IC chip 2, or two, or more than two. The radio frequency IC chip 2 is installed in the circuit in the lock seal 5. When the circuit in the lock seal 5 is connected to the external circuit, the radio frequency IC chip 2 can be read by the outside world.

[0069] In the present invention, the circuit is a conductive loop composed of metal wires and electrical and electronic components. When the circuit is connected, it generates current to work. The circuit can work by an external power supply or by RFID radio frequency identification technology. Different circuit functions can be achieved according to different electronic components connected to the circuit.

[0070] Electrical connection refers to connecting each segmented circuit directly through a mechanical structure so that the circuits are connected. The mechanical structure can be a metal wire, a conductive sheet, a conductive block or a conductive plate, etc. In the present invention, the access end of the circuit refers to the end that can connect the circuit. The access end is attached to a physical mechanical component. The mechanical component can be a conductive sheet, a conductive block or a conductive plate, etc. The exposed parts of the wire, conductive sheet, conductive block and conductive plate constitute a conductive area (also called a conductive cell). The conductive area is composed of countless conductive contacts. Connecting any conductive contact will connect to its corresponding circuit. When there is current in the circuit, the circuit will perform corresponding work. In the invention, the conduction between the radio frequency antenna circuit and the circuit in the lock seal 5 is achieved by the conductive locking elastic moving part 3.

[0071] In this embodiment, the first connection circuit and the second connection circuit include other electronic components to form a radio frequency antenna circuit. The electronic components include resistors, capacitors, amplifiers, etc., which are not limited here one by one, as long as the corresponding functions are achieved. The radio frequency IC chip integrates the product information such as the type, quantity, and specifications of the locked products and other related information, such as geographic location information. Since the conductive locking elastic moving part 3 has an elastic function, the conductive locking elastic moving part 3 can bounce up when the force is applied, and can automatically bounce back after the force is removed, thereby realizing that the conductive locking elastic moving part 3 automatically abuts against the circuit access end for electrical connection, and the two are tightly and stably connected.

[0072] Please refer to the following for further information Figure 1 and Figure 5 , at least one side of the lock seal 5 is concavely provided with a sliding groove 51, and one end of each disconnection that is not connected to the conductive locking elastic moving part 3 is provided with a conductive portion 52 that can conduct electricity, and the conductive portion 52 is located on the surface of the lock seal 5, and at least one conductive portion 52 is paved on the inner wall of at least one sliding groove 51, and the length dimension of the conductive portion 52 is a, 0mm<a≤200mm, such as two conductive portions 52, or three conductive portions 52, or more than three conductive portions 52 are paved on the inner wall of a sliding groove 51;

[0073] Among them, the conductive locking elastic moving part 3 electrically connected to the first connection circuit is named as the first conductive locking elastic moving part 301, and the conductive locking elastic moving part 3 electrically connected to the second connection circuit is named as the second conductive locking elastic moving part 302, and the two corresponding conductive parts 52 are named as the first conductive part 521 and the second conductive part 522. The inner wall of a sliding groove 51 is paved with the first conductive part 521 and / or the second conductive part 522, and the first conductive locking elastic moving part 301 and the second conductive locking elastic moving part 302 respectively realize the conduction of the first circuit of the lock seal by holding and touching with the first conductive part 521 and the second conductive part 522, thereby realizing its electrical connection with the radio frequency antenna 1.

[0074] In this embodiment, Figure 5The mechanical structure such as a wire, etc., that electrically connects the circuit in the lock seal 5 to the conductive locking elastic moving part 3 is not shown. The conductive part 52 is conductive and is used to electrically connect to the circuit in the lock seal 5. The conductive part 52 occupies a certain surface area on the lock seal 5. The surface of the conductive part 52 is preferably a plane, but can also be a curved surface, which is designed according to the needs of use. The conductive part 52 has a certain length, which can ensure that the circuit is still in a conductive state during the insertion or withdrawal of the lock seal 5 from the lock body 4, and different signals are transmitted. At the same time, it is beneficial to control all disconnected parts in a conductive state. It should be noted that the conductive parts 52 connected to different access ends of different circuits are different conductive parts 52, and the exposed surface of the conductive part 52 is a conductive contact surface (not marked). The conductive contact of the conductive part 52 contacts the conductive locking elastic moving part 3 to connect the two circuits. The length dimensions of the conductive part 52 are 1mm, 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, 16mm, 17mm, 18mm, 19mm, 20mm, 21mm, 30mm, 40mm, 50mm, 60mm, 70mm, 80mm, 90mm, 150mm, 160mm, 190mm, etc.

[0075] Among them, the sliding groove 51 plays a limiting role on the conductive locking elastic moving part 3. The sliding groove 51 allows the conductive locking elastic moving part 3 to slide along the sliding groove 51, that is, it limits the sliding path of the conductive locking elastic moving part 3 on the lock seal 5, thereby improving the accuracy and stability of the electrical connection between the conductive locking elastic moving part 3 and the disconnection point. At the same time, it prevents the locking device from sliding relative to the lock seal 5 due to external impact or vibration, resulting in the separation of the conductive locking elastic moving part 3 and the conductive part 52, which affects the use effect, enhances the relative position stability of the conductive locking elastic moving part 3 and the lock seal 5, can keep the lock seal 5 locked in place, improves the use performance, and extends the service life of the locking device.

[0076] The lock seal 5 may be provided with a sliding groove 51 on one side, or on two sides (not shown) or more than two sides (not shown), and at least two convex ribs 53 are provided on the surface of the lock seal 5, and the adjacent convex ribs 53 and the lock seal 5 therebetween form a sliding groove 51. At least one conductive part 52 is located on the bottom wall or side wall of the sliding groove 51, and the length direction of the conductive part 52 is arranged in parallel with the length direction of the convex rib 53, or the width direction of the conductive part 52 is arranged in parallel with the length direction of the convex rib, or the length direction of the conductive part 52 is arranged between the length direction and the width direction of the convex rib 53. The convex rib 53 and the lock seal 5 can be integrally formed or separately provided, and the separately provided convex rib 53 is connected to the surface of the lock seal 5 by welding, gluing, clamping, etc. When the lock seal 5 is provided with a plurality of sliding grooves 51, the plurality of sliding grooves 51 are arranged in parallel. The sliding grooves 51 can be arranged along a straight line or a curve, such as the groove walls of the sliding grooves 51 forming concentric circles. Some sliding grooves 51 are not provided with a conductive part 52, and some sliding grooves 51 are provided with one, two, or more than two conductive parts 52.

[0077] In some other embodiments, please refer to Figure 6 The surface of the lock seal 5 may not have the sliding groove 51 , the conductive part 52 is directly laid on the surface of the lock seal 5 , and there are also limiting wings 54 .

[0078] Please refer to the following for further information Figure 7 The sealing device further comprises a circuit board 6, wherein at least one circuit is arranged in the circuit board 6, one of which is named as a first circuit of the circuit board, and two access terminals 61 of the first circuit of the circuit board are exposed on the surface of the circuit board 6;

[0079] Among them, when the first conductive locking elastic moving part 301 and the second conductive locking elastic moving part 302 are not in contact with the lock seal 5, the first conductive locking elastic moving part 301 and the second conductive locking elastic moving part 302 are both in contact with the two access ends 61 of the first circuit of the circuit board, so that the first connection circuit and the second connection circuit lock are connected with the first circuit of the circuit board.

[0080] In this embodiment, when the locking device is in an unlocked or unlocked state, at least the first conductive locking elastic moving member 301 and the second conductive locking elastic moving member 302 abut against the circuit board 6 under the elastic force they possess, and are electrically connected to the two access terminals 61 of the first circuit board, and the first circuit board includes at least one circuit board radio frequency IC chip 62. Therefore, when the circuit board radio frequency IC chip 62 in the first circuit board is read, it can be determined that the locking device is in a locked, unlocked or unlocked state;

[0081] When the locking device is in the locked state, the lock seal 5 is located between the circuit board 6 and at least the first conductive locking elastic moving part 301 and the second conductive locking elastic moving part 302, and the lock seal 5 cuts off the contact with the two access ends 61 of the first circuit of the circuit board, and the first conductive locking elastic moving part 301 and the second conductive locking elastic moving part 302 are respectively held and touched with the first conductive part 521 and the second conductive part 522, so that the RF circuit is turned on. Therefore, according to the reading of the RF IC chip 2 located in the complete RF circuit formed by the first circuit of the lock seal and the RF antenna 1, it can be judged that the locking device is in the locked state, and the first circuit of the circuit board is disconnected at this time. It is convenient for inventorying when used in batches to obtain the number of locking devices and their locked states. The first circuit of the circuit board can be used to obtain product information, etc. As long as the switching between circuits is obtained by this method, it is within the protection scope of the present invention.

[0082] It is understandable that the circuit board 6 may also include other circuit board circuits (not shown), such as the circuit board 6 including a second circuit board circuit, when the locking device is in a locked state, the second circuit board circuit is connected or disconnected with the circuit in the lock seal 5, and when the locking device is in an unlocked or unlocked state, the second circuit board circuit is connected with the circuit in the lock seal 5. In the present invention, at least one conductive locking elastic moving part 3 is used to control different circuit board circuits to be combined and connected with the circuit in the lock seal 5, so that the RF antenna 1 and the RF IC chip 2 are used in multiple combinations to realize the functions of different circuits.

[0083] In some other embodiments, please refer to Figure 8 , an access end 61 of the first circuit of the circuit board is exposed on the surface of the circuit board 6, and another access end of the first circuit of the circuit board is electrically connected to the first connection circuit through a conductive structure such as a wire, and at least one conductive locking elastic moving part 3 can be detachably contacted with an access end of the second connection circuit to form an electrical connection. When the locking device is in an unlocked or unlocked state, at least one conductive locking elastic moving part 3 presses against the circuit board 6 under its own elastic force and is electrically connected to an access end 61 of the first circuit of the circuit board. The first circuit of the circuit board is fixedly connected or detachably connected to the circuit access end of the radio frequency antenna 1, such as by plugging, sleeve connection, screw connection, welding, etc. to achieve electrical connection with the radio frequency antenna circuit, and the radio frequency antenna circuit includes a first connection circuit and a second connection circuit.

[0084] In order to enhance the holding and supporting strength of the conductive locking elastic moving part 3, and avoid deformation due to insufficient supporting strength of the conductive locking elastic moving part 3, resulting in loose connection or separation between the conductive locking elastic moving part 3 and the circuit board 6 and the lock seal 5, thereby affecting the locking effect. The locking device also includes another first conductive locking elastic moving part 301, and the two first conductive locking elastic moving parts 301 are connected in parallel to an access end of the first connection circuit to increase the compressive strength, and the end of the disconnection point that is not connected to the first conductive locking elastic moving part 301 is connected in parallel to the two first conductive parts 521, wherein, when the locking device is in the locking state, the two first conductive locking elastic moving parts 3 are respectively held against the two first conductive parts 521, wherein at least one first conductive locking elastic moving part 301 is electrically connected to its corresponding first conductive part 521 to conduct the radio frequency circuit.

[0085] When the locking device is in the locked state, only one of the two first conductive locking elastic moving parts 301 needs to be electrically connected to a first conductive part 521 to meet the circuit connection function. Fig. 9 When the locking device is in the locking state, the two first conductive locking elastic moving parts 301 are electrically connected to the two first conductive parts 521. It is known to those skilled in the art that other disconnected parts may be provided with two conductive locking elastic moving parts 3, or more than two conductive locking elastic moving parts 3, such as three, four, five, etc. The end of the disconnected part that is not connected with the first conductive locking elastic moving part 3 may also be provided with only one first conductive part 521, and one of the two first conductive locking elastic moving parts 301 is used to conduct with the first conductive part 521. That is, the first conductive locking elastic moving part 301 may also be used only to increase the supporting strength without being connected to the circuit, such as a reinforced conductive locking elastic moving part 3 arranged in parallel with the first conductive locking elastic moving part 301, and the reinforced conductive locking elastic moving part 3 is not connected to the circuit, or the two first conductive locking elastic moving parts 301 are connected to the same circuit access end, and the two share the pressure of the lock seal 5, thereby increasing the strength of supporting the lock seal 5, and also preventing the first conductive locking elastic moving part 301 from being worn due to long use time. It can be understood that the above-mentioned pressure resistance method can be adopted at the disconnection point, and two, three or more conductive locking elastic moving parts 3 are connected in parallel at one end of the disconnection point.

[0086] An antenna is a converter that converts the guided waves propagating on the transmission line into electromagnetic waves propagating in an unbounded medium (usually free space), or vice versa. RFID electronic seals can also be used in sealing devices. When the sealing device is in a sealed state, the radio frequency IC chip can be read. Among them, the ideal antenna does not consider the feed part, but in order to lead out the signal, the lead-out point is called the feed part, which is expressed in English as feedpoint. The addition of the feed part generally affects the field distribution of the antenna, and the selection of this point is also particular.

[0087] The application of RFID electronic tags currently used in the market is limited by external environmental factors. For example, the signal read by the RFID reader is easily interfered and diffracted in water, liquid or high-humidity air, resulting in a high error rate of the reading signal. In addition, if the RFID electronic tag is attached to an object with a metal surface, it will also cause a high error rate in data reading or even make it impossible to read.

[0088] Specifically, the RF antenna 1 is a ceramic antenna, or a loop antenna, or a circuit board antenna, or a wire antenna. The ceramic antenna uses a ceramic shell and has anti-interference, anti-lightning, waterproof and dustproof capabilities. The loop antenna is a structure in which a metal wire is wound into a certain shape, such as a circle, square, triangle, etc., with the two ends of the conductor as output ends. An antenna that is wound with multiple turns (such as spiral or overlapping windings) is called a multi-turn loop antenna. The main forms of wire antennas include dipole antennas, half-wave oscillator antennas, cage antennas, monopole antennas, whip antennas, tower antennas, spherical antennas, magnetic antennas, V-shaped antennas, diamond antennas, fishbone antennas, Yagi antennas, log-periodic antennas, antenna arrays, etc. (see non-directional antennas, weakly directional antennas, and strongly directional antennas). Please refer to Fig.10 The circuit board antenna includes a radio frequency antenna board 10, one side of the radio frequency antenna board 10 is paved with a metal layer (not shown), and the other side is paved with an antenna 12. The thickness of the radio frequency antenna board 10 is any value between 0.1mm and 100mm, such as 2.3mm, 2.4mm, 2.5mm, 2.6mm, 2.7mm, 2.8mm and 2.9mm. Among them, on the one hand, the metal layer shields the influence of external signals on the circuit board antenna 10, and on the other hand, the electromagnetic waves emitted by the antenna hit the metal layer, and the metal layer can reflect part of the electromagnetic waves, thereby enhancing the electromagnetic wave intensity of the antenna and improving the ability of the antenna to transmit wireless signals, that is, improving the gain. The radio frequency antenna board 10 with a thickness of any value between 0.1mm and 100mm can ensure that the ultra-high frequency RFID antenna and the high frequency RFID antenna can be read. For example, if the design is 2.6mm, the interference between the two is small. The ultra-high frequency RFID antenna is connected to the radio frequency circuit. When the locking device is in the locking state, the high frequency RFID antenna can work or not work, and is controlled according to the specific design.

[0089] Please refer to further Fig.11 and Fig.12 The lock body includes a first lock body 41 and a second lock body 42.

[0090] The first lock body includes a plastic shell 411 and a metal inner shell 412. A first receiving groove is provided inside the plastic shell 411, and a second receiving groove is provided inside the metal inner shell 412. The metal inner shell 412 is received in the first receiving groove. A limiting structure cooperating with the metal inner shell 412 is provided on the inner wall of the first receiving groove, so that a receiving space is formed between the top wall of the first receiving groove and the top wall of the second receiving groove. The radio frequency antenna 1 is installed in the receiving space, and a side of the circuit board antenna covered with a metal layer faces the top wall of the second receiving groove.

[0091] The second lock body 42 is detachably connected to the first lock body 41, and the metal inner shell 412 is penetrated by a first socket, and the first socket is communicated with the second receiving groove. The circuit board 6 is located in the second receiving groove, and one end of the conductive locking elastic moving part 3 having a force-bearing inclined surface 31 is located in the first socket (not marked). The second lock body 42 is penetrated by a second socket (not marked). When the second lock body 42 and the first lock body 41 are engaged and connected, the first socket is connected to the second socket.

[0092] Among them, the metal inner shell 412 can effectively prevent the structural combustion of the internal sealing device from extending to the outside of the metal inner shell 412, avoiding causing a fire in the environment where the sealing device is located. At the same time, the metal inner shell 412 has shock-proof and explosion-proof functions.

[0093] Please refer to it again Figure 5 and Figure 6 , a limiting wing 54 is formed at one end of the lock seal 5 to prevent the lock seal 5 from being inserted further into the first plug hole, and the limiting wing 54 is located at the opposite end of the end inserted into the lock body 4, and a limiting wing 54 is formed at one end of the lock seal body, and the length dimension of one end of the lock seal body with the limiting wing 54 is greater than the aperture dimension at the opening of the second plug hole. When the second lock body 42 and the first lock body 41 are engaged and connected, the first plug hole is connected with the second plug hole, and the end of the lock seal 5 used to be inserted into the lock body passes through the second plug hole to the first plug hole locking position, so that the lock sealing device 100 forms a locked state, and the limiting wing 54 is located around the opening of the second plug hole, and the part of the lock seal body inserted into the first plug hole and the second plug hole is connected with the gap of the first plug hole and the second plug hole, and the gap is greater than zero. It can be understood that the shape of the plug hole matches the shape of the part where the lock seal is inserted, and the shape of the circumferential cross section of the plug hole can be a long strip, a circle, a semicircle, a square, a polygon or other regular and irregular shapes.

[0094] Alternatively, the buckle structure is at least one fixing hole 55 formed at one end of the lock seal 5, and the second lock body 42 and / or the first lock body 41 are provided with at least one limiting column (not shown) cooperating therewith, and a limiting column is inserted into a fixing hole 55 so that the lock seal 5 is fixed in position for locking. In the present invention, the plastic shell 411 reduces or eliminates signal interference to the RF antenna 1 board, and the metal inner shell 412 shields the interference of the outside world to the RF antenna 1 on the one hand, and on the other hand, the electromagnetic waves emitted by the RF antenna 1 hit the metal inner shell 412, and the metal inner shell 412 can reflect part of the electromagnetic waves, thereby enhancing the electromagnetic wave strength of the antenna and improving the ability of the RF antenna 1 to transmit wireless signals. The side of the RF antenna board 10 with the metal layer faces the top wall of the second receiving groove, further enhancing the electromagnetic wave transmission strength of the RF antenna 1. The limiting structure supports and clamps the RF antenna 1 board, and the RF antenna board 10 is limited in the receiving space to prevent the RF antenna board 10 from shaking, thereby affecting the effect of the RF antenna 1 receiving and transmitting electromagnetic waves. The second lock body 42 is connected with the first lock body 41 by snapping, and the relative position of the second lock body 42 and the first lock body 41 is fixed to prevent relative movement or separation, and then connected into one body, which is convenient for further locking. The lock seal 5 is inserted into the first jack and the second jack to realize the physical locking and radio frequency circuit conduction of the locking device 100. The limiting wing 54 is convenient for holding, and it is convenient to accurately find the position for inserting the second lock body 42 and the first lock body 41 to realize locking.

[0095] Among them, the lock seal 5 also includes a lock seal second circuit. When the lock seal device 100 is in a locked state or an unlocked state, the lock seal second circuit is connected to the circuit in the first lock body 41 or the second lock 42 through at least one conductive locking elastic moving part 3.

[0096] The second lock body 42 further includes at least one conductive locking elastic moving part 3, and the conductive locking elastic moving part 3 is used to conduct with the circuit in the lock seal 5;

[0097] When the locking device 100 is in a locked state or an unlocked state, at least one conductive locking elastic moving part 3 is connected to the circuit in the lock seal 5. The conductive locking elastic moving part 3 in the second lock body 42 can be connected to one circuit in the lock seal 5, or two or more, which can be set according to the required functions of the locking device 100.

[0098] Specifically, the radio frequency IC chip 2 is located in the first circuit of the lock seal; or the radio frequency IC chip 2 is located in the first lock body 41 ; or the radio frequency IC chip 2 is located in the second lock body 42 .

[0099] Specifically, the conductive locking elastic moving part 3 is a barbed conductive part, or a push pin / push post, or a thin sheet.

[0100] Please refer to it again Figure 5At least one limiting groove 511 is recessed on the bottom wall of at least one sliding groove 51, and a conductive portion 52 is located in a limiting groove 511. Of course, two conductive portions 52 can also be located in the same limiting groove 511 without limitation;

[0101] The surface of a side wall of at least one limiting groove 511 coincides with its orthographic projection on the horizontal plane or is set at an acute angle. The surface of the side wall is supported by a horizontal force, thereby preventing the barb from continuing to move. The side wall constitutes a stop structure 56.

[0102] In this embodiment, when the lock seal 5 is inserted into the first lock body and the second lock body, when the lock seal 5 interacts with the two force-bearing inclined surfaces 31 of the first conductive locking elastic moving part 301 and the second conductive locking elastic moving part 302, the first conductive locking elastic moving part 301 and the second conductive locking elastic moving part 302 are bounced up, and the lock seal 5 is inserted between the circuit board 6 and the first conductive locking elastic moving part 301 and the second conductive locking elastic moving part 302 and slides forward to the locking position, the two ends of the first conductive locking elastic moving part 301 and the second conductive locking elastic moving part 302 are bounced from the bottom wall of the sliding groove 51 into the bottom wall of the limiting groove 511, until they are connected to the conductive part 52 of the bottom wall to form a locked state. The limiting groove 511 and the conductive locking elastic moving part 3 are used to form a concave-convex clamping position at one end connected thereto, and the inner wall of the limiting groove 511 constitutes a stop structure 56 to ensure that the lock seal 5 inserted into the lock body is reversely pulled out or withdrawn from the lock body 4 to avoid unlocking. At the same time, the first and second conductive locking elastic moving parts slide from the bottom wall of the sliding groove 51 into the bottom wall of the limiting groove 511. The user's hand can receive a perception due to vibration, and obtain that the lock seal 5 has been connected to the radio frequency circuit to ensure that the locking device 100 is locked. The limiting wing 54 is limited to the opening periphery of the second jack and the conductive locking elastic moving part 3 is engaged with the stop structure 56 to form a lock on the mechanical structure of the locking device 100. The lock seal 5 makes the first lock body 41 and the second lock body 42 unable to be separated. Without destroying the structure of the locking device 100, the lock seal 5 can neither continue to be pushed into the first lock body 41 nor withdrawn from the first lock body 41 and the second lock body 42.

[0103] In some embodiments, the stop structure may also be other structures, such as a stop structure (not shown) protruding from the sliding groove 51, the stop structure includes a sliding slope and a blocking surface, the sliding slope and the blocking surface are connected at one end away from the body seal by a connecting portion, the sliding slope and its projection on the horizontal plane are set at an acute angle, when the sliding slope is subjected to a horizontal force, the force-applying object slides upward along the sliding slope; the blocking surface coincides with its projection on the horizontal plane or is set at an acute angle, when the blocking surface is subjected to a horizontal force, the force-applying object is pressed against the blocking surface and is prevented from continuing to move forward; the surface of the connecting portion is a smooth curved surface, and the curved surface includes a circular curved surface, an arc-shaped curved surface, and an elliptical curved surface.

[0104] Please refer to Figure 2 and Fig.13 The barb conductive member includes a barb, and the barb includes a force-bearing inclined surface 31 and a hook groove 32. The side of the barb facing away from the hook groove 32 is configured as the force-bearing inclined surface 31. The surface of the lock seal 5 is configured with at least one stop structure 56 that cooperates with the barb, so that after the lock seal 5 is inserted into the first insertion hole and reversely withdrawn from the lock body 4, at least one side of the barb with the hook groove 32 gradually approaches and abuts against a stop structure 56, thereby preventing the lock seal 5 from continuing to move backward.

[0105] For details, please refer to Fig.14 and Fig.15 The barb conductive member includes a metal body, a barb is formed at one end of the metal body, the metal body is connected to the mounting member 7 in the lock body 4 by an elastic connection, and a connecting shaft (not shown) is constructed at the connection;

[0106] The metal body is used to connect the mounting piece 7, and one end of the surface is covered with a plastic molding layer 33. At least one connecting column 331 is constructed on the plastic molding layer 33. A connecting hole (not marked) passes through the inside of the connecting column 331, and a torsion spring 8 is sleeved on the outside. At least one connecting column 331 is sleeved on the connecting shaft 34, and the connecting shaft 34 is installed on the mounting piece 7. The conductive locking elastic moving piece 3 realizes elastic movement through the torsion spring 8.

[0107] In this embodiment, the material of the barb conductive member is a conductive material, and the metal body is conductive, preferably copper, and may also be other metals, such as iron, alloy, gold, silver, aluminum, and their products, etc. Of course, the material of the barb conductive member may also be other conductive materials, as long as it can achieve the corresponding conductive function.

[0108] In the present invention, the conductive locking elastic moving part 3 can be elastically connected by elastic parts such as compression springs 8. For example, one end of the conductive locking elastic moving part 3 has an elastic connection structure, and the elastic connection structure is used to elastically connect with an external connection part. The elastic connection structure also includes a torsion arm groove for engaging a torsion arm. One torsion arm of the torsion spring is engaged with a torsion arm groove, and the other torsion arm is engaged with the external connection part, so that the side of the conductive locking elastic moving part 3 facing away from the torsion arm groove supports the external connection part. When the conductive locking elastic moving part 3 is subjected to a pressing force, the conductive locking elastic moving part 3 is compressed and moves circumferentially around the connecting axis. When the force is withdrawn, the elastic potential energy of the torsion spring is converted into kinetic energy, so that the conductive locking elastic moving part 3 can bounce back to its original position or retreat toward the original position until it is supported by the circuit board 6 or the lock seal 5.

[0109] In the present invention, the number of the conductive locking elastic moving parts 3 is set as required. The number of the conductive locking elastic moving parts 3 can be 3, 4, 5, 6, 7, 8, 9, 10, etc. Two or more conductive locking elastic moving parts 3 are located on the mounting part 7, and the mounting part 7 can be as follows: Fig.14 The plate shape shown may also be other shapes, such as columnar, square, other regular or irregular shapes, etc.

[0110] Specifically, the barb of the barb conductive part is connected to the metal body at any angle, such as the position of the barb on the metal body including the left side, right side, top, bottom, front end, rear end, left rear side, front and back sides. The metal body is set horizontally or roughly horizontally, and the barb is higher than the metal body; or, the metal body is set roughly vertically, and the barb is located at the upper end or lower end of the metal body. Please refer to Fig.14 The metal body has a conductive connection terminal 35, which is used to directly connect to the circuit.
