如图 1、 图 2、 图 3所示， 一次性无源射频电子锁具， 包括锁杆 A和锁头 B , 所述的锁杆 A由塑料外套 1、 金属锁杆骨架 2、 射频识别 （RFID)芯片 3、 阻抗变换器 4、 导线 5、 接插金属套 6、 绝缘套 7、 避振绝缘橡胶 8、 沟槽 17、 导电网 18组成， 所述的锁头 B由钢座 9、 塑料内托 10、 塑料外套 11、 0型橡 胶圈 12、 接插金属针 13、 弹簧卡圈 14、 天线 15、 塑料外壳 16组成。 由锁杆、 锁头两部件插入前无法读取锁内信息， 插入后拉力可大于 1200kgf， 可以锁集 装箱门或其他金属箱， 金属箱体移动速度小于 20km/h时， 可以在 3.5m~6m距 离处读取此电子锁具内的所有信息识别和运输物流信息的跟踪记载，到达目的 地后， 用大力钳剪断锁杆， 所有信息无法读出， 并且无法恢复功能。 As shown in Fig. 1, Fig. 2 and Fig. 3, the disposable passive radio frequency electronic lock includes a lock lever A and a lock B. The lock lever A is made of a plastic outer casing 1, a metal lock bar skeleton 2, and radio frequency identification (RFID). ) chip 3, The impedance transformer 4, the wire 5, the plug metal sleeve 6, the insulating sleeve 7, the vibration-proof insulating rubber 8, the groove 17, the conductive mesh 18, the lock B is made of a steel seat 9, a plastic inner 10, a plastic The outer casing 11, the 0-type rubber ring 12, the plug metal needle 13, the spring collar 14, the antenna 15, and the plastic outer casing 16 are composed. The lock information can not be read before the lock rod and the lock head are inserted. The pull force after insertion can be more than 1200kgf, and the container door or other metal box can be locked. When the moving speed of the metal box is less than 20km/h, it can be 3.5m~6m. At the distance, all the information identification and transportation logistics information in the electronic lock are read. After reaching the destination, the lock lever is cut with a pliers, all the information cannot be read, and the function cannot be restored.
所述的射频识别（RFID)芯片 3根据使用的要求不同，可选用包括 U-Code, EM4424, EPC-G2等在内的各种芯片， 该芯片设于锁杆 A的底部， 并由避振 绝缘橡胶 8包覆， 可以读写各种信息。 所述的锁杆 A杆尖部分采用的内藏接 插金属套 6与金属锁杆骨架 2组成同轴电缆， 屏蔽了锁杆 A内腔的电子电路， 使锁杆 A没有插入锁头 B前无法读出电子信息。 所述的锁杆 A内腔中导线 5 从头到尾连接射频识别 （RFID) 芯片 3， 阻抗变换器 4， 接插金属套 6， 只要 任何一处剪断， 金属锁杆骨架 2和内导线 5变形， 无法恢复， 所有电子信息无 法读出。所述的锁杆 A釆用两条沟槽 17结构， 当一条无法锁住锁头 B时， 另 一条可以备用， 也可以两条并用， 保证锁具拉力强度。所述的锁头 B的钢座 9 设有斜面沟漕 19， 斜面沟漕 19与锁杆沟槽 17、 弹簧卡圈 14配合， 形成一个 越拉越紧的止回结构， 当锁杆 A与锁头 B插入并向外拉时， 越拉越紧， 拉力 可达到 1200kgf以上。所述的锁头 B的内藏接插金属针 13与锁杆 A内的接插 金属套 6作为同心圆电子连接，并且与各金属外壳构成电子回路， 由于是同心 圆安装插件， 所以锁杆 A与锁头 B可以任何旋转角度插入， 便于操作。 所述 的锁头 B的塑料外壳 16根据天线 15的实际需要， 可制成圆筒形、 方形、 T 形、三角形或扁平形。 所述的锁头 B内藏天线 15与钢座 9配合， 可组成 UHF 的螺旋天线、 微带天线、 半振子天线， 也可组成 VHF的线圈天线及低频的磁 棒天线，空心线圈天线。所述的锁具利用金属箱体门或金属墙面作为其射频反 射面， 加强了读写电子信息的讯号强度。所述的锁杆 A内藏阻抗变换器 4， 使 电子电路有良好的阻抗匹配。 所述的锁头 B内藏 0型橡胶圈 12， 当上锁后， 具有防雨水作用。  The radio frequency identification (RFID) chip 3 can be selected according to different requirements, and various chips including U-Code, EM4424, EPC-G2, etc. can be selected, and the chip is disposed at the bottom of the lock bar A, and is protected from vibration. The insulating rubber 8 is coated to read and write various information. The built-in socket metal sleeve 6 and the metal lock rod skeleton 2 are coaxial cables formed by the rod-shaped portion of the lock rod A, and the electronic circuit of the inner cavity of the lock rod A is shielded, so that the lock rod A is not inserted into the lock head B. Unable to read the electronic information. The wire 5 in the inner cavity of the lock bar A is connected to the radio frequency identification (RFID) chip 3 from the beginning to the end, the impedance transformer 4, and the metal sleeve 6 are inserted, and the metal lock bar skeleton 2 and the inner wire 5 are deformed as long as any one is cut. , Unable to recover, all electronic information cannot be read. The lock bar A has two grooves 17 structure. When one can not lock the lock B, the other one can be used alternately or in combination to ensure the tensile strength of the lock. The steel seat 9 of the lock B is provided with a bevel groove 19, and the bevel groove 19 cooperates with the lock bar groove 17 and the spring collar 14 to form a more and more tight check structure, when the lock rod A and When the lock B is inserted and pulled outward, the tension is tightened and the pulling force can reach 1200kgf or more. The built-in metal pin 13 of the lock B and the plug metal sleeve 6 in the lock bar A are connected as concentric circles, and form an electronic circuit with each metal casing. Since the concentric mounting plugs, the lock bar A and lock B can be inserted at any angle of rotation for easy operation. The plastic housing 16 of the lock B can be made into a cylindrical shape, a square shape, a T shape, a triangular shape or a flat shape according to the actual needs of the antenna 15. The built-in antenna 15 of the lock B cooperates with the steel seat 9 to form a UHF helical antenna, a microstrip antenna, a half-vibrator antenna, a VHF coil antenna, a low-frequency magnetic rod antenna, and an air-core coil antenna. The lock uses a metal box door or a metal wall as its radio frequency reflecting surface to enhance the signal strength of reading and writing electronic information. The lock lever A has a built-in impedance converter 4 to make the electronic circuit have good impedance matching. The lock head B has a 0-type rubber ring 12 embedded therein, and when locked, has a function of preventing rain.
本发明的锁杆 A和锁头 B两部件分开时， 由于锁头 B 内设有射频识别 (RPID) 芯片 3， 而锁杆 A虽然有射频识别 （RFID) 芯片 3， 但所有电子电 路均被金属锁杆骨架 2屏蔽，· 所以即使与读写机具的天线 23很近的位置也无 法读出信息， 由于锁杆 A的接插金属套 6是内藏的， 即使用手触摸也无法触 及到， 所以无法用人体作为天线 15读出倩息。 When the two parts of the lock lever A and the lock B of the present invention are separated, since the lock head B is provided with a radio frequency identification (RPID) chip 3, and the lock lever A has a radio frequency identification (RFID) chip 3, all the electronic electricity The road is shielded by the metal lock bar skeleton 2, so that the information cannot be read even if it is close to the antenna 23 of the reader/writer, since the plug metal sleeve 6 of the lock lever A is built-in, even if it is touched by hand Can not be touched, so the human body can not be used as the antenna 15 to read the rest.
当锁杆 A与锁头 B用于集装箱门锁环 21—次性上锁时， 如图 5所示， 由 于金属锁杆 A骨架与锁头 B内钢座 9均为钢材制成， 加上有斜面沟槽 19， 如 图 4所示， 不用工具无法打开， 此锁具具有很强的机械强度， 拉拨锁杆 A与 锁头 B， 拉力大于 1200kgfo When the lock lever A and the lock B are used for the container door lock ring 21 - the secondary lock, as shown in FIG. 5, since the metal lock rod A skeleton and the lock B inner steel seat 9 are made of steel, plus There is a bevel groove 19, as shown in Fig. 4, can not be opened without tools, the lock has strong mechanical strength, pull the lock lever A and the lock B, the pulling force is greater than 1200kgf o
当海关验查后上锁， 可以用读写机具 22对锁具进行读写操作， 在物流运 输时， 如图 6、 图 7所示， 只要集装箱 20在小于 20km/h速度运动时， 安装在 顶头或道路 24旁的读写扒具天线 23在距离锁具 3.5m~6m就能读到锁具内的 电子信息， 方便于物流跟踪控制。  When the customs checks and locks, the locks can be read and written by the reading and writing machine 22. In the case of logistics transportation, as shown in Fig. 6 and Fig. 7, as long as the container 20 is moving at a speed of less than 20 km/h, it is installed at the head. Or the reading and writing cooker antenna 23 next to the road 24 can read the electronic information in the lock at a distance of 3.5m~6m from the lock, which is convenient for logistics tracking control.
当集装箱 20到达目的地， 海关查验锁具信息开箱时， 用大力钳工具钳断 锁杆 A， 此时由于射频识别 （RFID)芯片 3与天线 15部分分离， 并且锁杆 A 变 ， 锁头 B孔内留下一段锁杆 A残头， 永远无法拉出残头， 所以此锁具无 法恢复， 锁具就完成了功能， 此全球唯一的海关信息和 ID号不复存在， 防止 了重复使用。 ' '  When the container 20 arrives at the destination and the customs checks the lock information out of the box, the lock lever A is clamped with a pliers tool. At this time, since the radio frequency identification (RFID) chip 3 is partially separated from the antenna 15, and the lock lever A is changed, the lock B is changed. There is a lock bar A in the hole, and the stump can never be pulled out. Therefore, the lock can not be restored, and the lock is completed. The world's only customs information and ID number no longer exist, preventing reuse. ' '
