Each of the second springs 75 is a set of compression springs disposed on the latching block 742 of the corresponding latching member 74. The two ends of the second springs 75 abut against the abutting block 741 of the corresponding latching member 74 and the inner wall of the peripheral wall 713. The second springs 75 are used to bias the abutting block 741 of the corresponding latching member 74 toward a disengaging direction D3 perpendicular to the moving direction D1, so that the abutting block 741 of each latching member 74 is in tight contact with the first block. The outer peripheral surface 723 of the two-bar body 722. When the latch 7 is sheared adjacent to the peripheral wall 713 at the head 711 to cause the first hole portion 716 to be exposed, the first spring 73 will project the inner rod 72 outward in the moving direction D1, so that the second rod 722 of the inner rod 72 The second hole portion 717 is removed and separated from the abutting block 741 of the two latch members 74. At this time, each of the second springs 75 bounces the corresponding latching member 74 into the second hole portion 717, and the latching block 742 of the latching member 74 is separated from the corresponding hooking hook 214 to release the locked state.

Preferably, in order to reduce the friction between the second rod 722 of the inner rod 72 and the abutting block 741 of each of the latching members 74, the inner rod 72 can be smoothly and quickly applied by the first spring 73. In the present embodiment, the outer peripheral surface 723 of the second rod body 722 has a circular shape, and the abutting block 741 of each of the latching members 74 includes an arcuate abutting surface 743 abutting against the outer peripheral surface 723. The contact surface 743 and the outer peripheral surface 723 are in a point contact state. Thereby, the friction between the abutting block 741 of each of the latching members 74 and the second rod body 722 can be effectively reduced, and when the inner rod 72 is ejected by the elastic force of the first spring 73, the second rod body 722 can be quickly The ground is separated from the abutting block 741 of the two latching members 74.

Referring to FIG. 3 and FIG. 4, before the latch 7 is inserted into the socket 2, the first end 511 of the plate 51 of the carrier 5 abuts against the carrier 5 by the actuating member 6 biasing toward the receptacle 212. The two blocking portions 35 in the metal shield 3 position the carrier 5 in the first position. At this time, the electronic tag 4 is positioned in the shielding space 31 of the metal shield 3 and is shielded by the metal shield 3, so that The electronic seal 200 is in an open state.

Referring to FIG. 3, FIG. 5 and FIG. 6, when the latch 7 and the socket 2 of the electronic seal 200 are sealed to a lock lever 9 of a container door, the plug 7 is first passed through a through hole 91 of the lock lever 9 in the insertion direction D2. And inserted into the shield space 31 of the metal shield 3 via the insertion hole 212 and the opening 33. During the movement of the latch 7 in the insertion direction D2, the tail portion 712 of the latch 7 first pushes the first end 511 of the carrier member 5 and drives the carrier member 5 to move in the insertion direction D2. Since the length extending direction of each of the elongated guide grooves 234 of the sleeve 23 is parallel to the insertion direction D2 and communicates with the corresponding elongated hole portion 223, the carrier 5 is moved during the insertion direction D2. The two ends 512 will penetrate into the elongated hole portion 223 of the through hole 221 and the elongated guide groove 234, and the flange 521 of the cylinder 52 compresses the actuating member 6 to deform and accumulate the return elastic force.

Subsequently, a beveled surface 744 of the latching block 742 of each of the latching members 74 will abut against a beveled surface 215 of the corresponding latching hook 214, and the splitting force of the two latching blocks 742 respectively applied to the beveled surfaces 215 of the latching hooks 214 will be two buckles. When the hooks 214 are externally supported, the two outer hooks 214 are slightly extended and deformed respectively, so that the respective latching blocks 742 can smoothly pass over the corresponding hooks 214. When the two latching blocks 742 respectively pass over the two hooks 214, the two outer walls 213 respectively drive the two hooks 214 to be reset, so that the latching blocks 742 are locked in correspondence. The hook 214, at this time, the latch 7 is positioned in the locked position. Since the lock lever 9 is restrained between the head 711 of the latch 7 and the socket 2, the electronic seal 200 can restrict the movement of the lock lever 9 to prevent the container door from being opened.

On the other hand, the carrier 5 is positioned in the second position by the pushing of the pin 6, and when the carrier 5 is positioned in the second position, the electronic tag 4 is moved away from the shielding space 31 of the metal shield 3 and corresponds to the position of the hollow portion 30. The electronic seal 200 is kept in a locked state, so that the RFID reader can read the identification code of the electronic tag 4.

Referring to FIG. 6, FIG. 7, FIG. 8 and FIG. 9, when the person concerned has cut the peripheral wall 713 between the head 711 and the socket 2 and the first rod portion 721 of the inner rod 72, the center hole 715 is cut. A hole portion 716 is exposed. At this time, the elastic force applied by the first spring 73 to the first rod body 721 ejects the inner rod 72 outward in the moving direction D1 to the first hole portion 716, so that the second rod body 722 moves away from the second portion 722. The hole portion 717 is separated from the abutting block 741 of the two latch members 74. At the same time, the elastic force of the abutting block 741 of the corresponding latching member 74 moves the latching member 74 in the disengaging direction D3, and the latching members 74 can be ejected into the second hole portion 717. The latching block 742 of each latching member 74 is separated from the corresponding latching hook 2214 to release the locked state.

When the latching block 742 of each latching member 74 is separated from the corresponding latching hook 214, the biasing member 6 biases the carrier member 5 toward the insertion hole 212, and the carrier member 5 moves in the moving direction D1 to make the panel body. The 51-electron electronic tag 4 is inserted into the shielding space of the metal shield 3 via the through hole 32. During the movement of the carrier 5 in the moving direction D1, the latch 7 is simultaneously pushed up to move in the moving direction D1, when the first end 511 of the carrier 5 abuts against the metal shield. In the case of the stopper 35 in the piece 3, the carrier 5 can no longer be moved and positioned in the first position. At this time, the electronic tag 4 is shielded by the metal shield 3, so that the electronic seal 200 is switched to the on state. When the electronic seal 200 is switched to the on state, the RFID reader cannot read the identification code of the electronic tag 4, thereby determining that the electronic seal 200 is damaged.

Referring to FIG. 10 and FIG. 11 , a second embodiment of the electronic seal of the present invention is generally the same as the first embodiment except that the metal shield 3 and the electronic tag 4 are disposed.

In this embodiment, the metal shield 3 is sleeved on the plate body 51 of the carrier 5 and adjacent to the second end 512. The through hole 32 of the metal shield 3 faces the insertion hole 212 of the socket 2 and is spaced apart from the plate body 51. Between the first end 511 and the second end 512.
