The data line is inserted into the charging interface 33, and the other end of the data line is connected to a power supply to charge the battery. In the embodiment, the seal body 4 is fixedly connected to the bottom wall of the sliding shell 2 by adhesion. Specifically, the lower end surface of the sliding shell 2 is fixedly connected with an adhesive block 41, and the back surface of the seal body 4 is adhered to the adhesive block 41.
[0037] The upper part of the bottom shell 1 has a plug-in interface adapted to the outer diameter of the sliding shell 2 for sliding insertion of the sliding shell 2. The inner side wall of the upper part of the bottom shell 1 is fixedly connected with a mounting protrusion 11. The sliding shell 2 has a mounting cavity 21. The bottom wall and the outer side wall of the sliding shell 2 are both provided with an avoiding slot 22 communicated with the mounting cavity 21 for sliding of the mounting protrusion 11. The top inner wall of the mounting cavity 21 is fixedly connected with a guide rod 23 slidingly arranged in the mounting protrusion 11. The bottom shell 1 is provided with a first elastic member for forcing the sliding shell 2 to slide upward and reset in a normal state. In the embodiment, the first elastic member is a first spring 24 arranged in the mounting cavity 21 and sleeved on the guide rod 23. The upper end of the first spring 24 is fixedly connected to the top inner wall of the mounting cavity 21, and the other end of the first spring 24 is fixedly connected to the upper end surface of the mounting protrusion 11.
[0038] Referring to Figure 1 , Figure 4The inner wall of the mounting cavity 21 is provided with a lock rod 25 which slides radially, and the inner side wall of the insertion port of the bottom shell 1 is provided with a locking hole 12 for insertion of the lock rod 25. The top shell 3 is provided with a safety unlocking module for driving the lock rod 25 to slide out of the locking hole 12, and the safety unlocking module includes a touch display screen 51 fixed to the upper end face of the top shell 3 and an electric cylinder 52 built in the mounting cavity 21 and fixedly connected to the upper end face of the control mainboard 5. The electric cylinder 52 and the touch display screen 51 are electrically connected to the control mainboard 5, the piston rod of the electric cylinder 52 is coaxially fixedly connected to the lock rod 25, the touch display screen 51 is used for inputting an unlocking instruction to obtain a stamping permission, and the control mainboard 5 controls the electric cylinder 52 to act according to the unlocking instruction. Specifically, the control mainboard 5 is in communication connection with a mobile terminal through a Bluetooth module, the mobile terminal is a user's mobile phone, the control mainboard 5 controls the touch display screen 51 to display a two-dimensional code of an application permission, the mobile terminal scans the two-dimensional code to enter an application permission submission program, and a person in charge of approval stamps to obtain the stamping permission. After obtaining the stamping permission, the control mainboard 5 controls the electric cylinder 52 to drive the lock rod 25 to slide out of the locking hole 12, thereby achieving unlocking.
[0039] Referring to Figure 4 , Figure 5 , Figure 6 The control mainboard 5 is provided with a counter, and the touch display screen 51 can display the number of stamping times. The inner walls of the opposite sides of the bottom shell 1 are both provided with first photoelectric sensors 17 which are electrically connected to the control mainboard 5, one of the first photoelectric sensors 17 is a transmitting end, and the other is a receiving end. The side wall of the sliding shell 2 is provided with a detection port 28 which penetrates radially, the axial direction of the detection port 28 is perpendicular to the axial direction of the lock rod 25, and the detection port 28 is located above the electric cylinder 52. When the sliding shell 2 drives the stamping body 4 to move downward to the position where the stamping surface of the stamping body 4 is flush with the lower end face of the bottom shell 1, the detection port 28 and the two first photoelectric sensors 17 are in a position state, the photoelectric sensor of the receiving end triggers a signal, and the control mainboard 5 controls the counter to count once. After the sliding shell 2 moves upward to reset, the detection port 28 and the two first photoelectric sensors 17 are in a dislocation state, and the stamping body 4 is located below the first photoelectric sensors 17, effectively blocking the signal transmission between the two first photoelectric sensors 17 to avoid false triggering of counting.
[0040] The inner wall of the bottom shell 1 is hinged with a pair of symmetrically arranged sealing plates 13. Both ends of the sealing plates 13 are fixedly connected with hinge ear plates 14. The outer side wall of the hinge ear plates 14 is hinged to the inner wall of the bottom shell 1 through the hinge shaft 15. The lower end edge of the sliding shell 2 is fixedly connected with a linkage plate 26. The stamp surface of the stamp body 4 protrudes from the lower end surface of the linkage plate 26. The outer wall of the linkage plate 26 protrudes and is fixed with a linkage rod 27. The linkage rod 27 is located on one side of the hinge shaft 15. The hinge ear plate 14 has a linkage groove for the linkage rod 27 to slide and abut against, thereby driving the hinge ear plate 14 to rotate around the hinge point. The linkage groove has a first guide surface 141 and a second guide surface 142. The first guide surface 141 is parallel to the surface of the sealing plate 13. Under normal conditions, the two sealing plates 13 are in a parallel state to close the opening of the bottom shell 1. When the linkage rod 27 slides towards the bottom shell 1, the linkage rod 27 abuts against the first guide surface 141, forcing the hinge ear plate 14 to rotate in the forward direction, so that the sealing plate 13 rotates to a vertical state. The second guide surface 142 is an arc surface. When the linkage rod 27 slides away from the bottom shell 1, it abuts against the second guide surface 142, forcing the hinge ear plate 14 to rotate in the reverse direction, so that the sealing plate 13 rotates to a horizontal state.
[0041] Reference Figure 5 , Figure 7 In this embodiment, the seal body 4 is a copper seal. Taking the sealing plate 13 in a horizontal state as an example, an ink block 16 is installed on the upper end of the sealing plate 13. The upper end of the sealing plate 13 has a sliding groove 131. The groove of the sliding groove 131 extends to the ends of the sealing plate 13 that are far apart from each other. A magnetic plate 161 is fixedly connected to the back of the ink block 16 and is slidably inserted into the sliding groove 131. A magnetic strip 132 is fixedly connected to the inner wall of the sliding groove 131. The magnetic strip 132 and the magnetic plate 161 attract each other. When the sealing plate 13 is rotated to a horizontal state, the upper end of the ink block 16 abuts against the seal surface of the seal body 4.
[0042] The implementation principle of a security seal with a camera in this application embodiment is as follows: Under normal conditions, the sliding shell 2 moves upward under the action of the first spring 24, causing the seal body 4 to retract into the inner cavity of the bottom shell 1. The linkage rod 27 abuts against the second guide surface 142, forcing the hinge ear plate 14 to rotate in the opposite direction, causing the sealing plate 13 to rotate to a horizontal state to close the opening of the bottom shell 1, so that the seal surface information of the seal body 4 cannot be directly obtained. At the same time, the locking rod 25 is inserted into the locking hole 12, effectively restricting the downward movement of the sliding shell 2, thereby preventing unauthorized stamping behavior.
[0043] When the seal is needed, the device is started by the switch button, the mobile terminal scans the two-dimensional code and enters the application permission submission program, and the seal is approved by the approver to obtain the seal permission. After obtaining the seal permission, the control mainboard 5 controls the electric cylinder 52 to drive the lock rod 25 to slide out of the locking hole 12, so as to realize unlocking, and the display screen displays the seal times limit. The camera 32 starts recording video, the bottom shell 1 is placed at the seal position, the user presses the top shell 3, the sliding shell 2 moves downward, thereby driving the seal body 4 to move downward. In the process of moving the sliding shell 2 downward, the linkage rod 27 abuts against the first guide surface 141 to force the hinged lug plate 14 to rotate forward to make the sealing plate 13 rotate to the vertical state. At this time, the sealing plate 13 is located on one side of the inner wall of the bottom shell 1 and outside the sliding shell 2, so that the opening of the bottom shell 1 is in an open state. The sliding shell 2 continues to move downward, and at this time the linkage rod 27 still abuts against the first guide surface 141 to force the sealing plate 13 to always be in the vertical state. When the seal body 4 contacts the seal paper, the detection port 28 and the two first photoelectric sensors 17 are in the aligned state, the photoelectric sensor of the receiving end triggers the signal, the control mainboard 5 controls the counter to count once, and the seal is completed. After the seal is completed, the force applied to the top shell 3 is removed, the first spring 24 forces the sliding shell 2 to move upward relative to the bottom shell 1 to reset, and the linkage rod 27 abuts against the second guide surface 142 to force the hinged lug plate 14 to rotate reversely to make the sealing plate 13 rotate to the horizontal state to close the opening of the bottom shell 1, and the upper end surface of the ink pad 16 abuts against the seal surface of the seal body 4. The seal times of the touch display screen 51 are consumed once. When the seal times of the touch display screen 51 are consumed, the electric cylinder 52 drives the lock rod 25 to slide and insert into the locking hole 12, and the camera 32 ends the shooting.
[0044] Embodiment 2:
[0045] The difference from embodiment 1 is that, referring to Figure 8 , the inner wall of the bottom shell 1 is provided with a second photoelectric sensor 18, the second photoelectric sensor 18 is a transmitting end or a receiving end, the outer wall of the sliding shell 2 is provided with a third photoelectric sensor 29, the third photoelectric sensor 29 is a receiving end or a transmitting end, and the second photoelectric sensor 18 and the third photoelectric sensor 29 are electrically connected to the control mainboard 5. In this embodiment, the second photoelectric sensor 18 is a transmitting end, and the third photoelectric sensor 29 is a receiving end. Under normal circumstances, the second photoelectric sensor 18 and the third photoelectric sensor 29 are in a misaligned state. When the sliding shell 2 drives the seal body 4 to move downward to the position where the seal surface of the seal body 4 is flush with the lower end surface of the bottom shell 1, the second photoelectric sensor 18 and the third photoelectric sensor 29 are in an aligned state, the third photoelectric sensor 29 triggers a signal, and the control mainboard 5 controls the counter to count once.
