Description

Technical Field

[0001] This application relates to the field of financial supplies technology, and more specifically to a financial seal with anti-loss function. Background Technology

[0002] The financial seal (also known as the official financial seal) is an important seal for an organization to handle accounting, bank settlements, and other financial-related business. Its use and management must strictly comply with laws and regulations; therefore, the daily safekeeping of the financial seal is particularly important. The financial seal consists of the seal body and a handle fixed to its back. This type of financial seal is easily lost during use.

[0003] Some financial seals also have GPS positioning functions installed. However, to prevent others from removing them, the GPS positioning modules and other components are sealed inside the financial seal in a non-removable manner. This makes it difficult to repair these components. On the other hand, the GPS positioning components installed inside the financial seal can be damaged by someone deliberately disassembling it, thus rendering the financial seal without GPS positioning function and unable to be effectively protected.

[0004] In view of this, the inventor has designed a financial seal with anti-loss function and high security due to its detachability. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a financial seal with anti-loss functionality. Its advantages include linkage with mobile devices or computers, setting a fixed location for the financial seal, and issuing an alarm when it exceeds the set location range. The alarm on the financial seal itself is accompanied by a reminder from the mobile device or computer, and the location information of the financial seal is constantly transmitted to the linked mobile device or computer. The financial seal can only be disassembled by the designated owner, and it also has disassembly warning and low battery reminder functions, thereby achieving a high level of security by preventing loss and allowing for disassembly.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a financial seal with anti-loss function, comprising a seal body and a seal handle, wherein the seal body is provided with a placement groove, a battery is provided at the bottom of the placement groove, a control main board electrically connected to the battery is provided on the battery, the seal handle is used to seal the opening of the placement groove, the seal body is provided with a locking member for fixing the seal handle and electrically connected to the control main board, a fingerprint reader for recognizing fingerprints and electrically connected to the control main board is provided at the end of the seal handle away from the seal body, and a buzzer electrically connected to the control main board is provided on the seal body;

[0007] The control motherboard includes a main central processing unit (CPU), an Internet of Things (IoT) module electrically connected to the CPU and used for network communication between external mobile devices and a computer, a GPS module electrically connected to the CPU and used for locating the position of the device, a power detection chip electrically connected to the CPU and used for detecting battery power, and a secondary CPU. The secondary CPU is electrically connected to the locking mechanism, the battery, and the fingerprint scanner. The IoT module has Bluetooth functionality.

[0008] By adopting the above technical solution, before using the financial seal, pressing and holding the fingerprint scanner allows external mobile devices and computers to connect to the main central processing unit (CPU) via Bluetooth through the IoT module. The external mobile devices and computers can then control the control motherboard within the financial seal, enabling the CPU to establish network connectivity with the IoT module and record the seal owner's fingerprint. The CPU also controls the GPS module to set a fixed location for the financial seal within a designated area. When someone takes the financial seal and leaves the designated area, the GPS module, deviating from the designated range, sends a message to the CPU. Upon receiving the message, the CPU sends a command to the buzzer and IoT module. The buzzer emits a long beep to warn the financial seal that it has moved out of the designated area. The IoT module alerts the external mobile devices and computers via the network. Furthermore, the external mobile devices and computers can monitor the financial seal's location at all times through the IoT and GPS modules on the seal itself. When the battery power is low, the power detection chip detects this and sends a signal to the central controller. When the central controller's main processing unit receives information, it sends commands to the buzzer and IoT module. The buzzer emits an intermittent beeping sound to warn of low battery levels in the financial seal. The IoT module then alerts external mobile devices and computers via the network. When the financial seal needs to be disassembled for battery replacement or repair, external mobile devices and computers can use the IoT module to send a password to the main processing unit. The main processing unit then commands the locking mechanism to unlock, allowing the seal handle to be removed. Alternatively, fingerprints can be input into a fingerprint scanner, which sends information to the main processing unit, which in turn commands the locking mechanism to unlock, allowing the seal handle to be removed. When the main processing unit is operating normally, the secondary processing unit is in sleep mode. If the main processing unit malfunctions, the secondary processing unit automatically wakes up and sends commands to the buzzer and IoT module to indicate the malfunction. Fingerprint input can then be used to send information to the fingerprint scanner, which in turn commands the locking mechanism to unlock, allowing the seal handle to be removed.

[0009] In summary, the above-mentioned system, through the main central processing unit, IoT module, GPS module, and buzzer, enables real-time location monitoring and alarm alerts for the financial seal. The main central processing unit, secondary central processing unit, IoT module, locking mechanism, seal body, and handle provide internal protection for the financial seal. Furthermore, the power detection chip, battery, main central processing unit, IoT module, and buzzer enable real-time monitoring of the internal power level of the financial seal, thereby achieving the goal of preventing loss of the financial seal and ensuring high security through disassembly.

[0010] The present invention is further configured such that: the locking member includes a snap-fit ​​plate disposed on the side wall of the end of the stamp handle near the placement groove, a U-shaped snap-fit ​​disposed on the bottom of the end of the stamp handle near the placement groove and away from the snap-fit ​​plate, a miniature linear motor disposed in the placement groove and the moving rod acting on the U-shaped snap-fit, and an alarm button disposed in the placement groove and acting on the snap-fit ​​plate. The inner wall of the placement groove is provided with a snap-fit ​​groove that engages with the snap-fit ​​plate. The alarm button is installed in the snap-fit ​​groove and electrically connected to the control main board. The miniature linear motor is electrically connected to the control main board.

[0011] By adopting the above technical solution, when it is necessary to fix the handle to the stamp body, the snap-fit ​​plate can be inserted into the snap-fit ​​slot, and the snap-fit ​​plate can press the alarm button. The alarm button transmits a signal to the control motherboard, and the control motherboard issues a command to the micro linear motor, so that the telescopic rod of the micro linear motor is snapped into the U-shaped clip, thus sealing the stamp handle in the placement slot. When someone forcibly disassembles the stamp handle on the stamp body, the snap-fit ​​plate disengages from the snap-fit ​​slot, the alarm button loses its force, and a signal is transmitted to the control motherboard, so that the control motherboard issues a command to the IoT module and the buzzer to issue an alarm.

[0012] The present invention is further configured such that the inner wall of the placement groove is provided with a plurality of support strips that abut against the handle.

[0013] The present invention is further configured such that: the end of the stencil near the fingerprint scanner is threadedly connected to a sealing cap for sealing the fingerprint scanner.

[0014] By adopting the above technical solution, the sealing cover effectively protects the fingerprint scanner.

[0015] The present invention is further configured such that: a charging port for charging the battery and electrically connected to the control motherboard is provided on the end face of the stencil near the fingerprint sensor.

[0016] By adopting the above technical solution, the charging port can charge the internal battery without disassembling the financial seal, and can also power on the control board when the battery is empty or damaged.

[0017] The present invention is further configured such that both the body and the handle of the seal are made of alloy material.

[0018] In summary, this utility model has the following advantages:

[0019] 1. The main central processing unit, IoT module, GPS module and buzzer can realize real-time location monitoring and alarm of the financial seal. The main central processing unit, secondary central processing unit, IoT module, locking device, seal body and handle realize the protection of the internal of the financial seal. The power detection chip, battery, main central processing unit, IoT module and buzzer can realize real-time monitoring of the internal power of the financial seal, thereby achieving the purpose of preventing the financial seal from being lost and having high security through disassembly.

[0020] 2. When it is necessary to fix the handle to the body of the stamp, the snap-fit ​​plate can be inserted into the snap-fit ​​slot and the snap-fit ​​plate can press the alarm button. The alarm button transmits a signal to the control board, which then issues a command to the micro linear motor, causing the telescopic rod of the micro linear motor to snap into the U-shaped clip, thus sealing the stamp handle in the slot. When someone forcibly removes the handle from the body of the stamp, the snap-fit ​​plate disengages from the snap-fit ​​slot, the alarm button loses its force, and a signal is transmitted to the control board, causing the control board to issue a command to the IoT module and the buzzer to sound an alarm.

[0021] 3. By setting up a charging port, the internal battery can be charged without disassembling the financial seal, and the control board can also be powered on when the battery is empty or damaged. Attached Figure Description

[0027] The present invention will be further described in detail below with reference to the accompanying drawings.

[0028] A financial seal with anti-loss function, such as Figure 1 ,4 As shown, the stamp includes a body 1 and a handle 2 made of alloy material. The end of the body 1 away from the characters has a placement groove 3. A battery 4 is installed at the bottom of the placement groove 3. A control board 7 electrically connected to the battery 4 is installed on the battery 4. The handle 2 is used to seal the opening of the placement groove 3. A locking device for fixing the handle 2 and electrically connected to the control board 7 is installed on the body 1. A fingerprint scanner 5 for recognizing fingerprints and electrically connected to the control board 7 is installed at the end of the handle 2 away from the body 1. A buzzer 6 electrically connected to the control board 7 is installed on the body 1.

[0029] The control motherboard 7 includes a main central processing unit, an Internet of Things (IoT) module electrically connected to the main central processing unit for network communication between external mobile devices and computers, a GPS module electrically connected to the main central processing unit for locating the position of the body 1, a power detection chip electrically connected to the main central processing unit for detecting the power of the battery 4, and a secondary central processing unit. The secondary central processing unit is electrically connected to the locking component, the battery 4, and the fingerprint scanner 5. The IoT module has Bluetooth functionality.

[0030] like Figure 2 , 3 As shown, the locking mechanism includes a snap-fit ​​plate 8 fixed to the side wall of the stamp handle 2 near the placement slot 3, a U-shaped snap-fit ​​9 fixed to the bottom of the stamp handle 2 near the placement slot 3 and away from the snap-fit ​​plate 8, a miniature linear motor 10 fixed in the placement slot 3 and whose moving rod acts on the U-shaped snap-fit ​​9, and an alarm button 11 installed in the placement slot 3 and acting on the snap-fit ​​plate 8. The inner wall of the placement slot 3 has a snap-fit ​​groove 12 that engages with the snap-fit ​​plate 8. The alarm button 11 is installed in the snap-fit ​​groove 12 and electrically connected to the control main board 7. The miniature linear motor 10 is electrically connected to the control main board 7, and the U-shaped snap-fit ​​9 is also made of alloy material.

[0031] When it is necessary to fix the handle 2 to the body 1, the snap-fit ​​plate 8 can be inserted into the snap-fit ​​slot 12, and the snap-fit ​​plate 8 can press the alarm button 11. The alarm button 11 transmits a signal to the control motherboard 7, and the control motherboard 7 issues a command to the micro linear motor 10, so that the telescopic rod of the micro linear motor 10 is snapped into the U-shaped clip 9, and the handle 2 can be sealed in the placement slot 3. When someone forcibly disassembles the handle 2 on the body 1, the snap-fit ​​plate 8 is disengaged from the snap-fit ​​slot 12, the alarm button 11 loses its force, and a signal is transmitted to the control motherboard 7, so that the control motherboard 7 issues a command to the Internet of Things module and the buzzer 6 to issue an alarm.

[0032] like Figure 2 , 3 As shown, the inner wall of the placement groove 3 has several support bars 13 that abut against the handle 2.

[0033] like Figure 2 , 3As shown, the end of the handle 2 near the fingerprint scanner 5 is threaded with a sealing cap 14 for sealing the fingerprint scanner 5, which effectively protects the fingerprint scanner 5.

[0034] Furthermore, a charging port 15 for charging the battery 4 and electrically connected to the control motherboard 7 is installed on the end face of the seal handle 2 near the fingerprint sensor 5. This allows the internal battery 4 to be charged without disassembling the financial seal, and also allows the control motherboard 7 to be powered on when the battery 4 is depleted or damaged.

[0035] The working process and beneficial effects of this utility model are as follows:

[0036] By pressing and holding the fingerprint scanner 5, external mobile devices and computers can connect to the main central processing unit (CPU) via Bluetooth through the IoT module. These devices can then control the control motherboard 7 within the financial seal, enabling the CPU to establish network connectivity with the IoT module and record the seal owner's fingerprint. The CPU also controls the GPS module to set a fixed location for the seal within a designated area. When someone takes the seal and leaves the designated area, the GPS module sends a message to the CPU. Upon receiving this message, the CPU instructs the buzzer 6 and the IoT module to emit a long beep, warning the seal that it has moved out of range. The IoT module alerts the external mobile devices and computers via the network. These devices can also monitor the seal's location at all times through the IoT and GPS modules on the seal itself. When the battery 4's internal power is low, the power detection chip detects this and sends a message to the central controller. Upon receiving information, the processor can send commands to the buzzer 6 and the IoT module. The buzzer 6 will emit an intermittent beeping sound to warn that the internal battery of the financial seal is low. The IoT module will then send a warning to external mobile devices and computers via the network. When the financial seal needs to be disassembled for battery replacement 4 or repair, external mobile devices and computers can send a password to the main central processing unit (CPU) via the IoT module. The CPU will then issue a command to the locking mechanism, causing it to unlock and allowing the seal handle 2 to be removed. Alternatively, a fingerprint can be input into the fingerprint scanner 5, which will then transmit information to the CPU. The CPU will then issue a command to the locking mechanism, causing it to unlock and allowing the seal handle 2 to be removed. When the CPU is operating normally, the secondary CPU is in a dormant state. If the CPU malfunctions, the secondary CPU will automatically wake up and issue commands to the buzzer 6 and the IoT module to indicate that the CPU is damaged. The fingerprint can then be input into the fingerprint scanner 5, which will transmit information to the secondary CPU. The secondary CPU will then issue a command to the locking mechanism, causing it to unlock and allowing the seal handle 2 to be removed.

[0037] In summary, the main central processing unit, IoT module, GPS module, and buzzer 6 enable real-time location monitoring and alarm alerts for the financial seal. The main central processing unit, secondary central processing unit, IoT module, locking mechanism, seal body 1, and seal handle 2 provide internal protection for the financial seal. Furthermore, the power detection chip, battery 4, main central processing unit, IoT module, and buzzer 6 enable real-time monitoring of the internal power level of the financial seal, thereby achieving the goal of preventing loss of the financial seal and ensuring high security through disassembly.
