Description

Technical Field

[0001] The utility model relates to the technical field of container packaging equipment, in particular to an electronic container seal device for container security management based on RFID. Background Art

[0002] In the prior art, the container door is closed by a container seal mechanism. Specifically, one end of a metal insertion rod of the container seal mechanism is inserted into a lock seat body through two fixing holes of the container door to close the container door. Although the container seal mechanism satisfies security functions such as anti-theft and anti-destruction, due to structural limitations, there are still the following technical problems. Specifically, the staff can only manually check the customs declaration list of the corresponding container (including checking paper lists and retrieving data from databases such as the PC side, etc.) to understand the item information in the container (such as quantity, variety, etc.). In the above operation mode, it is relatively unintuitive to understand the item information data and it will also bring certain inconveniences to the staff.

[0003] The RFID electronic tag is a non-contact automatic identification technology. It identifies the target object through radio frequency signals and obtains relevant data. The identification work does not require manual intervention. As the wireless version of the barcode, the RFID electronic tag (which pre-stores relevant data of related items internally) has advantages that the barcode does not have, such as waterproof, anti-magnetic, high temperature resistance, long service life, large reading distance, the data on the tag can be encrypted, larger storage data capacity, and the stored information can be changed freely, etc. The electronic tag uses radio frequency transmission and reception of data. In practical applications, the interpreter of the reader system information processing center emits radio frequency signals. After the RFID electronic tag receives the radio frequency signals emitted by the interpreter, it sends out the corresponding item data information stored in the chip (Passive Tag, passive tag or passive label) by virtue of the energy obtained from the induced current, or actively sends the item data signal in the container (Active Tag, active tag or active label; its advantage is that the signal transmission is farther, but it needs to be powered by installing a battery); after the interpreter reads and decodes the information, it is sent to the reader system information processing center for relevant data processing and the relevant item information is obtained. Although the RFID electronic tag has been applied in many industries, it has not been effectively used in container management. In summary, it is very necessary to provide an electronic container seal mechanism with an RFID electronic tag that can facilitate the management staff to check the item data information in the container. Summary of the Utility Model

[0004] In order to overcome the drawbacks of the existing container door mechanisms due to their structural limitations as described in the background, the present utility model provides an RFID-based container security management electronic seal device which, under the combined action of relevant mechanisms, not only has the function of closing the container door to prevent theft and damage, but also enables the staff to conveniently understand various data of the items inside the container in a wireless non-contact manner when the container enters and exits relevant area crossings, etc., bringing convenience to the staff and correspondingly improving work efficiency.

[0005] The technical solution adopted by the present utility model to solve its technical problems is as follows:

[0006] An RFID-based container security management electronic seal device includes a passive RFID electronic tag module and a seal mechanism body. It is characterized in that the seal mechanism body includes a lock rod and a lock seat body. The outer side of the lock rod is covered with an insulating protective sleeve from top to bottom, and the bottom of the lock rod does not have a protective sleeve. There is a limit seat at the lower part of the lock rod, and the lower end of the limit seat is a cylindrical structure as an insertion seat, and limit rings are distributed on the outer side of the insertion seat; the inner side of the lock seat body is a hollow structure as a fixed cavity, there is a positioning ring at the upper end of the fixed cavity, there is a fixed ring in the fixed cavity, a retaining spring is movably sleeved in the fixed ring, and the passive RFID electronic tag module is installed at the lower end inside the fixed cavity; the antenna of the passive RFID electronic tag module is connected to the lower end of a spring, the insertion seat at the lower part of the lock rod is inserted into the fixed cavity of the lock seat body, and the inner side of the retaining spring is clamped in the limit ring.

[0007] Further, the limit seat of the lock rod is located within the positioning ring, and the outer diameter of the limit seat is smaller than the inner diameter of the positioning ring.

[0008] Further, the inner diameter of the part of the fixed cavity below the positioning ring is larger than the outer diameter of the insertion seat.

[0009] Further, the front end of the retaining spring has an opening, the outer diameter of the retaining spring is larger than the inner diameter of the fixed ring, and the inner diameter of the retaining spring is smaller than the inner diameter of the limit ring.

[0010] Further, after the inner side of the retaining spring is clamped in the limit ring, the outer side of the retaining spring is located within the fixed ring.

[0011] Further, the lower metal part of the lock rod is in contact with the upper end of the spring and is electrically conductive.

[0012] Further, the outer side end of the lock seat body is covered with an insulating sleeve, and the distance between the upper end of the lock seat body and the lower end of the lock head at the upper end of the lock rod is greater than the distance between the outer side ends of the two fixing holes of the container door.

[0018] Figure 1 、 2As shown in Figures 3 and 4, a RFID-based electronic container seal device for container security management includes a passive RFID electronic tag module body 1 (which pre-stores data related to the quantity and type of items inside the relevant container. Inputting data information of relevant items into the passive RFID electronic tag module body 1 is a mature existing technology, and this application does not claim any protection for this technical point) and a seal mechanism body. The seal mechanism body includes a lock rod 2 and a lock seat body 3. The outer side of the lock rod 2 is covered with an insulating protective sleeve 21 from top to bottom, and the top and bottom of the lock rod 2 are not covered by the protective sleeve. The lower outer side of the lock rod 2 is a rectangular structure as a limit seat 22, and the lower end of the limit seat 22 is a cylindrical structure as an insertion seat 23. A concave limit ring 24 is annularly distributed in the middle of the outer side of the insertion seat 23. The inner side of the lock seat body 3 is a hollow structure as a fixed cavity 31. The upper end of the fixed cavity 31 is a rectangular hollow structure as a positioning ring 32. There is an outwardly concave fixed ring 33 annularly distributed in the middle of the inner side of the fixed cavity. An annular spring clip 34 is movably sleeved inside the fixed ring 33. The passive RFID electronic tag module body 1 is installed on an insulating circuit board, and the circuit board is installed in the middle of the lower end inside the fixed cavity 31. The antenna of the passive RFID electronic tag module body 1 is welded to the lower end of a copper metal spring 4. The upper part of the metal spring 4 is located in the middle of the lower end inside the fixed cavity 31. The insertion seat 23 of the lock rod 2 is inserted into the fixed cavity 31 of the lock body seat from top to bottom, and the inner side of the spring clip 34 is clamped inside the limit ring 24.

[0019] Figure 1 、 2 As shown in Figures 3 and 4, the lock rod limit seat 22 is located inside the positioning ring 32, and the outer diameter of the limit seat 22 is slightly smaller than the inner diameter of the positioning ring 32 by 0.2 mm. The inner diameter of the fixed cavity 31 at the part below the positioning ring 32 is slightly larger than the outer diameter of the insertion seat 23 by 0.2 mm. The front end of the spring clip 34 has an opening (in this way, the spring clip made of carbon steel has elasticity). The outer diameter of the spring clip 34 is slightly larger than the inner diameter of the inner side end of the fixed ring 33, and the inner diameter of the spring clip 34 is smaller than the inner diameter of the limit ring 24. After the inner side of the spring clip 34 is clamped inside the limit ring 24, the outer side of the spring clip 34 is located inside the fixed ring 33, and the inner side is tightly sleeved inside the limit ring 24. The lower metal part of the lock rod 2 contacts the middle upper end of the spring 34. The outer side end of the lock seat body is covered with an insulating protective sleeve 5. The distance between the upper end of the lock seat body 3 and the lower end of the lock head 25 at the upper end of the lock rod is greater than the distance between the outer side ends of the two fixed holes of the container door.

[0020] Figure 1 、 2As shown in Figures 3 and 4, this new type is based on the passive RFID electronic tag module body 1 and the box sealing mechanism body 2. During application, the staff passes the lock rod 2 through two fixing holes of the container door, and then inserts the lower end insertion seat of the lock rod 2 into the lock seat body 3. The limit seat 22 is located within the positioning ring 32. In this way, it can position the lock rod, preventing the lock rod from rotating after being inserted into the lock seat body 3, which may cause the spring and other components to be affected by the rotational force and be damaged. During the process of inserting the lock rod into the lock seat body 3, since the outer side of the lower end insertion seat of the lock rod 2 has an arc-shaped structure, it can be inserted into the circlip 34 from top to bottom, causing the circlip 34 to open. The inner side of the circlip 34 is located within the limit ring 24 of the lock rod 2, and the outer side of the circlip 34 is located within the fixed ring 33 of the lock seat body. In this way, when someone tries to pry the upper end of the lock rod upward violently, the limit of the circlip 34 can prevent the separation of the lock rod and the lock seat body, playing a good role in anti-theft, etc. In this new type, when the container enters or exits relevant areas such as the crossing, the reader in the information processing center of the reader system in the management room of the crossing, etc., emits a radio frequency signal. After the RFID electronic tag body 1 installed on the corresponding container receives the radio frequency signal emitted by the reader, it sends out the data information of the items in the corresponding container stored in the chip by virtue of the energy obtained from the induced current. After the reader reads and decodes the information, it is sent to the information processing center of the reader system for relevant data processing. The personnel in the management room can directly obtain the information of the relevant items, bringing convenience to the staff and correspondingly improving the working efficiency of container customs clearance, etc. (reducing the time for the staff to manually include flipping through paper lists and retrieving the data of the items in the container from databases such as the PC side).
