[0038] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0039] Embodiment 1

[0040] like Figure 1-Figure 11As shown, an anti-leakage stamp alarm device comprises a protective shell 1, a vibration sensor system and a bottom plate 2, a clamping plate 3 is fixedly connected to the upper surface of the bottom plate 2, the bottom of the protective shell 1 is open, the protective shell 1 is clamped and connected with the clamping plate 3, and the bottom of the protective shell 1 abuts against the bottom plate 2, the outer wall of the clamping plate 3 and the inner wall of the protective shell 1 are interference fit, ensuring that the clamping plate 3 and the protective shell 1 are tightly fitted and not easy to fall off, two support plates 13 are fixedly connected to the two ends of the inner part of the clamping plate 3, two circuit board support rods 14 are fixedly connected between the two support plates 13, and the two circuit board support rods 14 are fixedly connected to the inner wall of the clamping plate 3 respectively;

[0041] The clamping plate 3, the supporting plate 13 and the circuit board supporting rod 14 are used to clamp the clamping groove 15 of the vibration sensor system;

[0042] The vibration sensing system includes a circuit board 4, an electrical main board 5, a vibration sensing unit 6 and a voltage comparator 7. The circuit board 4 is engaged in a locking groove 15. The circuit board 4 can be limited and fixed by the provided locking groove 15, and the bottom of the circuit board 4 is in contact with the circuit board support rod 14. The circuit board 4 is electrically connected to the electrical main board 5 and the intermediate relay 8. The electrical main board 5 is electrically connected to the vibration sensing unit 6 and the voltage comparator 7. The voltage comparator 7 is located at one end of the electrical main board 5, and the other end of the voltage comparator 7 is electrically connected to the circuit board 4 through a wire. The intermediate relay 8 is electrically connected to the voltage comparator 7 through the circuit board 4, and the intermediate relay 8 is electrically connected to the normally closed switch KA.

[0043] The vibration sensing unit 6 can receive the vibration and transmit the electrical signal to the voltage comparator 7. The vibration sensing unit 6 is electrically connected to the vibration switch K2. Specifically, before receiving the vibration, the voltage comparator 7 outputs a low level. The device is placed on the work platform and located near the stamping area. When the staff uses the stamping tool to stamp the bill, the work platform will also vibrate. At this time, the vibration sensing unit 6 in the protective shell 1 receives the vibration, and the vibration switch K2 in the vibration sensing unit 6 is instantly disconnected and controls the voltage comparator 7 to output a high level. After the vibration ends, the vibration switch K2 instantly returns to the normally closed state and controls the voltage comparator 7 to output a low level.

[0044] The circuit board 4 is also electrically connected to a power socket 9 and a data exchange socket 10, which are electrically connected to the vibration sensor system through the circuit board 4, the power socket 9 is electrically connected to a power line 11, the data exchange socket 10 is electrically connected to a data line 12, and the data exchange socket 10 is electrically connected to the induction alarm system through the data line 12;

[0045] The bottom of the power socket 9 abuts against the support plate 13, and the bottom of the data exchange socket 10 abuts against another support plate 13; the tops of the power socket 9 and the data exchange socket 10 abut against the top of the inner cavity of the protective shell 1. When the protective shell 1 is engaged with the engaging plate 3, the power socket 9 and the data exchange socket 10 are squeezed and fixed by the supporting plate 13 and the protective shell 1 to ensure stability during use;

[0046] When working, the staff only needs to plug one end of the power cord 11 into the computer and the other end into the power socket 9 to power the circuit board 4 through the computer, and then power the vibration sensing system, which is convenient and fast, and can achieve "plug and play".

[0047] Further, such as Figure 3 and Figure 4 As shown, a power socket 16 and a data line socket 17 are provided on the protective shell 1. The power line 11 passes through the power socket 16 to be electrically connected to the power socket 9. The data line 12 passes through the data line socket 17 to be electrically connected to the data exchange socket 10. The caliber of the power socket 16 is larger than the caliber of the data line socket 17. By setting different calibers, the staff can more intuitively distinguish the power socket 9 and the data exchange socket 10 when plugging.

[0048] Further, such as Figure 6 and Figure 7 As shown, the induction alarm system includes a keycap cover 18, a sensing unit 19, and an alarm prompt light 20. A mounting opening 21 is provided at the top of the inner surface of the keycap cover 18. The keycap cover 18 is transparent. The mounting opening 21 is provided on the keycap cover 18. The top of the sensing unit 19 is embedded in the bottom of the mounting opening 21. The free end of the data line 12 passes through the keycap cover 18 and is electrically connected to the sensing unit 19. The sensing unit 19 is electrically connected to an alarm switch K1. The alarm prompt light 20 is provided at the bottom of the sensing unit 19. The alarm prompt light 20 is electrically connected to the sensing unit 19. The bottom of the keycap cover 18 is detachably mounted with a fixed structure.

[0049] Further, such as Figure 6 As shown, the fixed structure includes a paddle 22 and a keyboard clip 23. The bottom of the keycap cover 18 is installed on the upper surface of one end of the paddle 22. The other end of the paddle 22 is fixedly connected to the keyboard clip 23. By setting the keyboard clip 23, the induction alarm system can be clamped on different types of keyboards to improve adaptability.

[0050] Specifically, after the sensing unit 19 is electrically connected to the data exchange socket 10 through the data line 12, the sensing unit 19 is powered, and the staff selects a specific key on the keyboard, clamps the keyboard clip 23 on the keyboard, and adjusts the paddle 22 and the key cap cover 18 to the top of the specific key. When the specific key needs to be pressed, the key cap cover 18 is touched first, and the sensing unit 19 is touched at the same time. After the sensing unit 19 in the key cap cover 18 is touched, the alarm switch K1 is closed, and the alarm indicator light 20 starts to flash to alarm, reminding the staff to stamp the relevant certificates and bills;

[0051] The device is placed on a work platform and located near the stamping area. When the staff uses the stamping tool to stamp the bill, the work platform will also vibrate. The vibration sensing unit 6 receives the vibration and controls the voltage comparator 7 to output a high level through the electrical mainboard 5. The voltage comparator 7 outputs a high level to the intermediate relay 8. At this time, the normally closed switch KA in the intermediate relay 8 is adsorbed and disconnected, and the vibration sensing system loses power instantly, thereby causing the sensing unit 19 to lose power, the alarm switch K1 to be disconnected, and the alarm prompt light 20 to stop flashing. After the vibration ends, the vibration switch K2 instantly returns to the normally closed state and controls the voltage comparator 7 to output a low level. At this time, the switch KA inside the intermediate relay 8 returns to the normally closed state, and the sensing unit 19 is powered on, waiting for the next person to be inspected;

[0052] If the current bill does not need to be stamped, the staff can also touch the sensing unit 19 on the specific key again with their hands, and the alarm indicator 20 will stop flashing, thereby removing the alarm and waiting for the next person to be inspected.

[0053] Embodiment 2

[0054] This embodiment is improved on the basis of the first embodiment as follows: Figure 2 As shown, the lower surface of the base plate 2 is detachably connected with a plurality of fixed suction cups 24, by which the device can be adsorbed at any position of the workbench and can prevent the device from hitting the ground due to external force during use, thereby causing malfunction of the device.

[0055] In summary, the workflow of the utility model is:

[0056] S1: During operation, the staff fixes the device on the working platform and in a position near the stamping area by means of the fixed suction cup 24, and then plugs one end of the power cord 11 into the computer and the other end into the power socket 9, and supplies power to the vibration sensing system through the computer.

[0057] S2: After the sensing unit 19 is electrically connected to the data exchange socket 10 through the data line 12, the sensing unit 19 is powered, and the staff selects a specific key on the keyboard, clamps the keyboard clip 23 on the keyboard, and adjusts the paddle 22 and the keycap cover 18 to above the specific key.

[0058] S3: When a specific key needs to be pressed, the key cap cover 18 will be touched first, and the sensing unit 19 will be touched at the same time. After the sensing unit 19 in the key cap cover 18 is touched, the alarm switch K1 is closed, and the alarm indicator light 20 starts flashing to remind the staff to stamp the relevant certificates and bills.

[0059] S4: When the staff uses the stamping tool to stamp the bill, the work platform will also vibrate. The vibration sensing unit 6 receives the vibration and controls the voltage comparator 7 to output a high level through the electrical mainboard 5. The voltage comparator 7 outputs a high level to the intermediate relay 8. At this time, the normally closed switch KA in the intermediate relay 8 is adsorbed and disconnected, and the vibration sensing system loses power instantly, thereby causing the sensing unit 19 to lose power, the alarm switch K1 to be disconnected, and the alarm prompt light 20 to stop flashing. After the vibration ends, the vibration switch K2 instantly returns to the normally closed state and controls the voltage comparator 7 to output a low level. At this time, the switch KA inside the intermediate relay 8 returns to the normally closed state, and the sensing unit 19 is powered on, waiting for the next person to be inspected.

[0060] S5: If the current bill does not need to be stamped, the staff can also touch the sensing unit 19 on the specific key again with their hand, and the alarm indicator light 20 will stop flashing, thereby removing the alarm and waiting for the next person to be inspected.

[0061] The above different embodiments can be combined, replaced and used in conjunction with each other.
