[0014] A control method for a visible fingerprint anti-theft electricity metering box padlock, comprising: S1: Slide the cover plate upward to make the second limit protrusion slide along the slide groove. At this time, the cleaning brush will slide on the surface of the door lock body to remove the unlocking traces left by the door lock body last time. Then, press the fingerprint on the fingerprint recognition area or insert the key into the mechanical keyhole to control the lock tongue to detach from the inside of the limit shell, so as to realize safe door opening; S2: When the cabinet door is forcibly opened to steal electricity, the vibration sensor senses the vibration and sends a signal to the controller. After receiving the signal, the controller controls the inverter to make the current direction from the battery change to the opposite state, so that the N pole and S pole of the electromagnet are switched. Since the magnet has the characteristic of repelling like poles, the electromagnet will provide repulsive force to the permanent magnet, so that the tension rod extends from the inside of the installation slot and enters the limiting plate, and at the same time pushes the micro switch, so that the buzzer and warning light work, which effectively serves as an alarm.

When the height of the cabinet needs to be adjusted, four sets of screw stepper motors simultaneously drive the screw in the middle to rotate. When the screw rotates, the upper connecting piece is moved closer to or away from the top surface of the screw stepper motor through the thread. Since the length of the guide column is unchanged, the second telescopic sleeve is pushed to slide inside the first telescopic sleeve through the lower connecting piece, thereby increasing the height of the cabinet and preventing rainwater from gathering and entering the cabinet when it rains in the city.

[0015] Compared with the prior art, the advantages of the present invention are: 1. The present invention provides a first locking mechanism and a second locking mechanism to protect the cabinet door through a double locking mechanism. This design significantly improves the anti-electricity theft capability of the power equipment. Even if one locking mechanism is illegally damaged, the other can still remain locked to ensure the safety of the power equipment. When the cabinet door is forcibly opened to steal electricity, the vibration sensor can quickly sense the vibration and send a signal to the controller. After receiving the signal, the controller can immediately start the inverter to change the direction of the current, and then use the same-pole repulsion between the electromagnet and the permanent magnet to extend the top rod and lock the cabinet door, while triggering the micro switch to start the buzzer and warning light to alarm. This instant response and alarm mechanism can effectively deter electricity theft and remind relevant personnel to take measures in time. After the alarm is triggered and the cabinet door is locked, the second locking mechanism can only be unlocked by the correct unlocking method of the first locking mechanism. This design not only ensures that the cabinet door can be easily unlocked under legal circumstances, but also avoids the possibility of illegal unlocking. At the same time, once the alarm is lifted, the second locking mechanism can also be easily reset to prepare for the next use.

[0016] 2. The present invention drives the threaded rod to rotate by setting a servo motor output end, so that the threaded block moves along the threaded rod. When moving, the threaded block pushes the hinge frame to extend and retract, thereby pushing the second telescopic rod, the third telescopic rod and the fourth telescopic rod to extend in sequence, and then the fourth telescopic rod pushes the baffle to slide between the limit bars through the connecting plate, so as to close the observation window to prevent forced window breaking and thus affecting the operation of the electrical equipment inside the cabinet. Through the cooperation of the servo motor and the telescopic rod, the observation window is quickly closed, thereby effectively preventing forced window breaking, protecting the electrical equipment inside the cabinet from damage, and effectively preventing illegal intrusion and destruction. At the same time, when no inspection is required, the telescopic assembly and the baffle can effectively prevent outsiders from spying on the wiring, equipment model and working status inside the distribution cabinet through the observation window, thereby enhancing the safety of the equipment.

[0029] A control method for a visible fingerprint anti-theft electricity metering box padlock comprises the following steps: S1: The cover plate 407 is slid upward to make the second limiting protrusion 408 slide along the slide groove 405.

After receiving the signal, the controller 1703 controls the inverter 1710 to make the current direction from the battery 1708 become opposite, so that the N pole and the S pole of the electromagnet 1704 are switched. At this time, the electromagnet 1704 will provide a repulsive force to the permanent magnet 1705, so that the tightening rod 1706 extends from the inside of the installation groove 1702 and enters the limiting plate 1712, and at the same time pushes the micro switch 21, so that the buzzer 11 and the warning light 10 work, which effectively plays an alarm role.

When the height of the cabinet 1 needs to be adjusted, the four sets of screw stepper motors 1806 simultaneously drive the screw in the middle to rotate. When the screw rotates, the upper connecting piece 1804 is moved closer to or away from the top surface of the screw stepper motor 1806 through the thread. Since the length of the guide column 1803 is unchanged, the second telescopic sleeve 1802 is pushed to slide inside the first telescopic sleeve 1801 through the lower connecting piece 1805, thereby achieving the height increase of the cabinet 1, preventing rainwater from gathering and causing water to enter the cabinet 1 when it rains in the city.

10. A control method for a visual fingerprint anti-theft electricity metering box padlock, using a visual fingerprint anti-theft electricity metering box padlock as described in claims 1-9, characterized in that: include: S1: The cover plate (407) is slid upward to allow the second limiting protrusion (408) to slide along the slide groove (405). At this time, the cleaning brush (409) slides on the surface of the door lock body (401) to remove the unlocking traces left by the door lock body (401) last time. Then, a fingerprint is pressed on the fingerprint recognition area (402) or a key is inserted into the mechanical key hole (404) to control the lock tongue (410) to detach from the inside of the limiting shell (411), thereby realizing safe door opening; S2: When the cabinet door (2) is forcibly opened to steal electricity, the vibration sensor (1709) senses the vibration and sends a signal to the controller (1703). After receiving the signal, the controller (1703) controls the inverter (1710) to change the direction of the current from the battery (1708) to the opposite state, so that the N pole and the S pole of the electromagnet (1704) are switched. Since magnets have the characteristic that like poles repel each other, the electromagnet (1704) will provide a repulsive force to the permanent magnet (1705), so that the pressing rod (1706) extends from the inside of the installation groove (1702) and enters the limiting plate (1712), and at the same time pushes the micro switch (21), so that the buzzer (11) and the warning light (10) work, which effectively serves as an alarm.

When moving, the threaded block (1609) pushes the hinge frame (1608) to extend and retract, thereby pushing the second telescopic rod (1602), the third telescopic rod (1603) and the fourth telescopic rod (1604) to extend in sequence, and then the fourth telescopic rod (1604) pushes the baffle (14) to slide between the limit bars (13) through the connecting plate (15), thereby closing the observation window (3) to prevent the window from being broken by force, thereby affecting the operation of the electrical equipment inside the cabinet (1); S4: The cabinet (1) is supported by a first telescopic sleeve (1801) and a second telescopic sleeve (1802). When the height of the cabinet (1) needs to be adjusted, four sets of screw stepper motors (1806) simultaneously drive the screw in the middle to rotate. When the screw rotates, the upper connecting piece (1804) is moved closer to or farther away from the top surface of the screw stepper motor (1806) through the thread. Since the length of the guide column (1803) is constant, the second telescopic sleeve (1802) is pushed to slide inside the first telescopic sleeve (1801) through the lower connecting piece (1805), thereby increasing the height of the cabinet (1) and preventing rainwater from gathering and causing water to enter the cabinet (1) when it rains in the city.
