Description

Technical Field

[0001] This utility model relates to the field of four types of library technology, specifically to a four-type library intrusion monitoring and early warning device. Background Technology

[0002] With the increasing demand for high-security storage in the financial and security sectors, Category IV vaults, as core storage facilities for storing cash boxes and highly confidential items, have become a key element in ensuring asset security. According to the national industry standard "Bank Security Requirements" and related security construction specifications, Category IV vaults must be equipped with reliable intrusion monitoring and early warning systems and must meet core requirements such as independent control zones, multi-factor authentication, and proactive early warning. They are widely used in scenarios such as rural commercial bank branches and service stations in remote mountainous areas, playing an important role in empowering branch transformation, reducing transportation costs, and improving service flexibility.

[0003] However, existing four types of library intrusion detection and early warning devices still have many technical pain points that need to be addressed in practical applications, making it difficult to fully meet the requirements for high security, high convenience, and high stability: 1. The early warning system is not reliable enough and is prone to false alarms and missed alarms. Some devices rely on a single circuit on / off or mechanical limit to achieve early warning, lacking a dual protection mechanism. The mechanical structure is easily affected by slight vibrations or external force, which can cause the locking parts to shift, leading to incorrect connection or separation of the power connection parts. The complex signal transmission links are easily interfered with, further increasing the probability of false alarms and missed alarms, and making it impossible to accurately identify legitimate operations and illegal intrusion behaviors.

[0004] 2. The early warning trigger is not stable enough and there is a risk of failure. When an illegal intrusion occurs, the mechanical limit structure of the traditional device is prone to jamming or other problems, which will cause the core locking component to fail to reset in time, thus causing the early warning function to fail. Utility Model Content

[0005] The purpose of this invention is to provide a four-category library intrusion monitoring and early warning device.

[0006] To achieve this objective, the present invention adopts the following technical solution: A four-category warehouse intrusion monitoring and early warning device is provided, comprising a four-category warehouse body and a warehouse door hinged to the surface of the four-category warehouse body. The surface of the warehouse door is equipped with a combination lock. The device also includes an early warning mechanism and a release mechanism. The early warning mechanism is installed inside the four-category warehouse body and includes a monitoring base, a locking pin, an electronic connector, a power connector, and an alarm. The monitoring base is fixed inside the four-category warehouse body. The locking pin is slidably connected in a moving groove opened inside the monitoring base. The electronic connector is fixed to the through end surface of the locking pin. The power connector is fixed to the lower surface of the monitoring base and is adapted to the electronic connector, and is directly opposite the power-connecting side of the electronic connector. The release mechanism is installed between the locking pin and the four-category warehouse body. The release mechanism includes an electric telescopic rod and a connecting seat. The connecting seat is fixed to the side of the locking pin away from the electronic connector. The electric telescopic rod is fixed inside the four-category warehouse body, and the output end of the electric telescopic rod faces the surface of the connecting seat.

[0007] Preferably, a fixed plate is slidably connected inside the monitoring base, and a U-shaped pusher is fixed on the surface of the fixed plate. Several sets of springs arranged at equal intervals are fixed between the fixed plate and the monitoring base. A locking tooth group is fixed on the side of the fixed plate away from the springs. The locking tooth group consists of several sets of locking teeth arranged at equal intervals. The inclined surface of the locking teeth of the locking tooth group is adapted to the inclined surface of the top of the locking pin.

[0008] Preferably, a tension spring is fixed between one side of the locking pin and the four types of storage bodies, and a through hole adapted to the tension spring is opened inside the monitoring seat. When the tension spring is naturally contracted, it can pull the locking pin to maintain the initial position, ensuring that the electronic connector and the power connector are in the connected state.

[0009] Preferably, the early warning mechanism further includes a permanent magnet, an electromagnet, and a locking gear assembly. The permanent magnet is fixed in the middle of the surface of the push frame, and the electromagnet is fixed in the surface of the monitoring base. The electromagnet and the permanent magnet are arranged opposite to each other, and the magnetism generated by the electromagnet after being energized is the same as that of the permanent magnet, which can generate a repulsive force.

[0010] Preferably, limit blocks are symmetrically fixed on both sides of the surface of the locking pin, and a limit groove adapted to the limit block is opened inside the monitoring seat to limit the movement stroke of the locking pin and prevent the electronic connector from deviating when it docks with the power connector. The side of the back surface of the four types of warehouse near the monitoring seat is slidably connected to the storage cavity for easy maintenance and repair of the warning mechanism. The alarm is electrically connected to the power connector through a wire, and the electronic connector is electrically connected to an external power supply. When the electronic connector contacts the power connector, the alarm forms a power circuit and starts the alarm.

[0011] Preferably, a fixed boss is fixed at the output end of the electric telescopic rod, and a movable boss is slidably connected to the surface of the output end of the electric telescopic rod at the position corresponding to the fixed boss. The movable boss and the fixed boss are arranged symmetrically, and a spring array in a ring is fixed between the fixed boss and the movable boss.

[0012] Preferably, the release mechanism further includes a locking block, a positioning slide rod, and a spring. Two sets of locking blocks are symmetrically slidably connected in the locking grooves opened inside the connecting seat. The locking blocks have a trapezoidal structure and an inclined surface is opened on the side of the locking block facing the electric telescopic rod. The positioning slide rod is fixed to one side of the surface of the locking block and is slidably connected in the positioning groove opened inside the connecting seat. The spring is sleeved on the surface of the positioning slide rod, and the two ends of the spring are respectively fixed between the locking block and the connecting seat. When the electric telescopic rod extends, the locking block is embedded in the locking groove and compresses the spring, thereby realizing a stable connection between the electric telescopic rod and the connecting seat.

[0013] Preferably, in the initial state, spring two is in the extended state, the locking block is between the fixed boss and the movable boss, the combination lock is electrically connected to the electric telescopic rod, after the correct combination lock is entered, the electric telescopic rod remains in the initial retracted state, the locking connecting seat drives the locking pin to stretch the tension spring to generate elastic force, and with the cooperation of the locking gear group, the electronic connector and the power connector are separated, and the alarm state is released. After the combination lock continuously enters the wrong combination, it can control the electric telescopic rod to extend a short distance and push the fixed boss and the movable boss toward the connecting seat until the movable boss passes the locking block. Then, under the action of the tension spring, the locking pin is pulled to move the connecting seat toward the side away from the electric telescopic rod. During this period, the arc surface of the fixed boss and the movable boss and the inclined surface of the locking block can make the electric telescopic rod automatically disengage from the connecting seat, thereby causing the electronic connector and the power connector to automatically contact, so that the alarm forms a power circuit and starts the alarm.

[0014] The beneficial effects of this utility model are: 1. This utility model discloses a four-category warehouse intrusion monitoring and early warning device. Through the deep collaborative design of the early warning mechanism, the deactivation mechanism, and the four types of warehouse bodies and doors, it specifically addresses the core pain points of traditional four-category warehouse intrusion monitoring, such as poor early warning reliability, cumbersome legal operation, and weak illegal protection. It achieves comprehensive optimization of the monitoring and early warning function from six dimensions: initial start-up adaptability, early warning monitoring accuracy, legal operation convenience, illegal protection security, component operation stability, and ease of maintenance. After the device is powered on, it can automatically complete the monitoring and early warning function without manual debugging. Even non-professionals can quickly power on and activate the device, solving the cumbersome problem of traditional monitoring devices requiring manual calibration of power-connecting components and adjustment of limit structures.

[0015] 2. This utility model discloses a four-category warehouse intrusion monitoring and early warning device with an illegal protection closed-loop design. It links locking and alarm to minimize the risk of intrusion. Illegal operation triggers an alarm and the warehouse door locks, providing dual protection to block the intrusion path. After repeated incorrect password entries, the device will not only send an alarm signal through the alarm to promptly remind staff to pay attention to the abnormality, but will also simultaneously control the warehouse door to close completely, preventing unauthorized personnel from intruding through multiple attempts or by forcibly pushing the door. This forms a protective closed loop of early warning, reminder, and physical blockage. Compared with traditional devices that only have a single alarm, it can more directly prevent intrusion and reduce the security risk of items in the four types of warehouses.

[0016] 3. This utility model provides a four-category intrusion monitoring and early warning device, offering dual protection for both early warning and monitoring. It accurately identifies intrusion behavior, eliminating false alarms and missed alarms. The inclined surfaces of the locking teeth and locking pin are properly fitted, and with the elastic reset effect of the spring, the position of the locking pin is stably restricted, preventing displacement of the locking pin due to slight vibration or external force. This also prevents misconnection or separation of the electronic connector and the power connector. The alarm's on / off state depends entirely on the precise connection between the electronic connector and the power connector. Furthermore, the electronic connector is connected to an external power supply, and the alarm is connected to the power connector via wires. The circuit logic is simple and direct, without complex signal transmission links, reducing false alarms and missed alarms caused by signal interference. It ensures that the alarm is only activated when an illegal operation triggers the component linkage, improving the accuracy of the early warning.

[0017] 4. This utility model provides a four-category warehouse intrusion monitoring and early warning device. In the event of illegal intrusion, it employs a dual linkage of mechanical disengagement and electromagnetic avoidance to ensure the early warning system remains effective. When illegal operation occurs, not only will the electric telescopic rod automatically disengage from the connecting seat, but the electromagnet power supply will also be simultaneously activated. Utilizing the repulsive force between the electromagnet and the permanent magnet, the pusher, fixing plate, and locking gear assembly will be pushed aside, completely releasing the locking gear assembly's restriction on the locking pin. This prevents the locking pin from failing to reset due to jamming of the locking gear assembly, ensuring the tension spring can smoothly pull the locking pin back into position. This allows for precise docking of the electronic connector and the power connector, triggering the alarm and eliminating the possibility of early warning failure during illegal intrusion, thus improving protection reliability.

To better illustrate the embodiments of the present invention, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product.

[0022] Reference Figures 1 to 6The device illustrates a Class IV warehouse intrusion monitoring and early warning system, comprising a Class IV warehouse body 1 and a warehouse door 2 hinged to the surface of the Class IV warehouse body 1. The surface of the warehouse door 2 is fitted with a combination lock. The system also includes an early warning mechanism 3 and a release mechanism 18. The early warning mechanism 3 is installed inside the Class IV warehouse body 1 and includes a monitoring base 5, a locking pin 12, an electronic connector 14, a power connector 15, and an alarm 16. The monitoring base 5 is fixed inside the Class IV warehouse body 1. The locking pin 12 is slidably connected to a movable groove inside the monitoring base 5. The electronic connector 14 is fixed to the through end surface of the locking pin 12. The power connector 15 is fixed to the lower surface of the monitoring base 5 and is adapted to the electronic connector 14, directly facing the power-connecting side of the electronic connector 14. The release mechanism 18 is installed between the locking pin 12 and the Class IV warehouse body 1 and includes an electric telescopic rod 19 and a connecting base 2. 3. The connecting seat 23 is fixed on the side of the locking pin 12 away from the electronic connector 14. The electric telescopic rod 19 is fixed inside the four-category storage body 1, and the output end of the electric telescopic rod 19 faces the surface of the connecting seat 23. In the initial state, in the release mechanism 18, the electric telescopic rod 19 is fixed inside the four-category storage body 1. The fixed boss 20 at the output end of the electric telescopic rod 19 and the movable boss 21 that is slidably connected are connected by springs 22 arranged in a ring array. The two are in a naturally extended state and maintain a preset gap. The connecting seat 23 is fixed on the side of the locking pin 12 away from the electronic connector 14. The two sets of symmetrical locking blocks 24 in the locking groove inside the connecting seat 23 are kept in an outward extended state under the action of the positioning slide rod 25 and spring 26. The tension spring 13 is in a naturally contracted state and can pull the locking pin 12 to maintain the initial position, ensuring that the electronic connector 14 and the power connector 15 are in a connected state.

[0023] Reference Figures 1 to 3 The monitoring base 5 is internally slidably connected to a fixing plate 6. A U-shaped pusher 8 is fixed to the surface of the fixing plate 6. Several sets of springs 7 are fixed between the fixing plate 6 and the monitoring base 5. A locking tooth group 11 is fixed to the side of the surface of the fixing plate 6 away from the springs 7. The locking tooth group 11 is composed of several sets of locking teeth arranged at equal intervals. The inclined surface of the locking teeth of the locking tooth group 11 is adapted to the inclined surface of the top of the locking pin 12.

[0024] Reference Figures 1 to 3 A tension spring 13 is fixed between one side of the locking pin 12 and the fourth type of storage body 1, and a through hole adapted to the tension spring 13 is opened inside the monitoring seat 5. When the tension spring 13 is naturally contracted, it can pull the locking pin 12 to maintain the initial position, ensuring that the electronic connector 14 and the power connector 15 are in the connected state.

[0025] Reference Figure 3The early warning mechanism 3 also includes a permanent magnet 9, an electromagnet 10, and a locking gear assembly 11. The permanent magnet 9 is fixed in the middle of the surface of the push frame 8, and the electromagnet 10 is fixed in the surface of the monitoring base 5. The electromagnet 10 is arranged opposite to the permanent magnet 9, and the magnetism generated by the electromagnet 10 after being energized is the same as that of the permanent magnet 9, which can generate a repulsive force.

[0026] Reference Figures 3 to 4Limiting blocks 17 are symmetrically fixed on both sides of the surface of the locking pin 12. The monitoring seat 5 has a limiting groove inside that matches the limiting block 17 to limit the movement of the locking pin 12 and prevent the electronic connector 14 from shifting when it connects with the power connector 15. The back surface of the Class IV storage body 1, near the monitoring seat 5, is slidably connected to the maintenance door 4 through the storage cavity, which facilitates the maintenance and repair of the warning mechanism 3. The alarm 16 is electrically connected to the power connector 15 through a wire, and the electronic connector 14 is electrically connected to an external power supply. When the electronic connector 14 contacts the power connector 15, the alarm 16 forms a power circuit and activates the alarm. When the Class IV storage body 1 is powered on and put into use, the electric telescopic rod 19 will extend initially, thereby driving the fixed boss 20 and the movable boss 21. As the electric telescopic rod 19 moves closer to the connecting seat 23, its extension stops when the fixed boss 20 at the end of the electric telescopic rod 19 passes the locking block 24. At this time, the locking block 24 is embedded in the gap between the fixed boss 20 and the movable boss 21, initially achieving the limiting engagement between the electric telescopic rod 19 and the connecting seat 23. Subsequently, the electric telescopic rod 19 immediately retracts and resets. The fixed boss 20 and the movable boss 21 at its output end exert a pulling force on the connecting seat 23 through the locking block 24 in the gap, thereby causing the locking pin 12 fixed to the connecting seat 23 to slide along the surface of the locking tooth assembly 11. The inclined surface at the top of the locking pin 12 and the inclined surface of the teeth of the locking tooth assembly 11 are pressed against each other. Because the spring-7 has an elastic buffering effect, the fixing plate 6 will move closer to the spring-7. A slight slide causes the locking gear assembly 11 to briefly move aside, allowing the locking pin 12 to move smoothly. Once the locking pin 12 reaches the preset release position, the spring 7 returns to its extended position, pushing the fixing plate 6 and the locking gear assembly 11 back to their original positions. The sides of the teeth of the locking gear assembly 11 engage with the top side of the locking pin 12, preventing the locking pin 12 from resetting under the force of the tension spring 13. This ensures the locking pin 12 remains stable at the preset alarm release position. In this state, the tension spring 13 between the locking pin 12 and the four-category storage body 1 is stretched, generating a force that returns it to its initial position. The tension spring 13 passes through a preset through hole inside the monitoring seat 5 to prevent jamming. The locking pin 12 passes through the electronic connector 14 on the end surface and the electrical female connector 1 on the lower surface of the monitoring seat 5. 5. Separate the electronic base 14 and connect it to the external power supply. The alarm 16 is connected to the power socket 15 via a wire. At this time, the alarm 16 is not turned on, and the device is in the warning state. At the same time, the combination lock on the surface of the vault door 2 is electrically connected to the electric telescopic rod 19, waiting for the input of the operation command. At this time, the electromagnet 10 is not energized and does not generate magnetism. It does not generate a repulsive force with the permanent magnet 9 in the middle of the push frame 8. The position of the push frame 8 is stable, thereby keeping the locking tooth assembly 11 on the other side of the fixing plate 6 fixed. The tooth bevel of the locking tooth assembly 11 fits properly with the top bevel of the locking pin 12, restricting the movement of the locking pin 12. At the same time, the limiting blocks 17 on both sides of the surface of the locking pin 12 are embedded in the limiting groove of the monitoring base 5, restricting the movement of the locking pin 12.Avoid offset.

[0027] Reference Figure 2 , Figure 5 A fixed boss 20 is fixed at the output end of the electric telescopic rod 19. A movable boss 21 is slidably connected to the surface of the output end of the electric telescopic rod 19 at the position corresponding to the fixed boss 20. The movable boss 21 and the fixed boss 20 are arranged symmetrically. A spring 22 arranged in a ring array is fixed between the fixed boss 20 and the movable boss 21.

[0028] Reference Figures 5 to 6 The release mechanism 18 also includes a locking block 24, a positioning slide rod 25, and a spring 26. Two sets of locking blocks 24 are symmetrically slidably connected in the locking grooves opened inside the connecting seat 23. The locking blocks 24 have a trapezoidal structure and an inclined surface on the side of the locking blocks 24 facing the electric telescopic rod 19. The positioning slide rod 25 is fixed to one side of the surface of the locking blocks 24 and is slidably connected in the positioning grooves opened inside the connecting seat 23. The spring 26 is sleeved on the surface of the positioning slide rod 25, and the two ends of the spring 26 are respectively fixed between the locking blocks 24 and the connecting seat 23. When the electric telescopic rod 19 extends, the locking blocks 24 are embedded in the locking grooves and compress the spring 26, thereby achieving a stable connection between the electric telescopic rod 19 and the connecting seat 23.

[0029] Reference Figures 5 to 6Initially, spring 22 is in the extended state, and locking block 24 is positioned between fixed boss 20 and movable boss 21. The combination lock is electrically connected to the electric telescopic rod 19. After the correct combination lock is entered, the electric telescopic rod 19 remains in its initial retracted state. Locking connector 23 drives locking pin 12 to stretch spring 13, generating elastic force. With the cooperation of locking gear 11, the electronic connector 14 separates from the electrical connector 15, releasing the warning state. After the combination lock continuously enters incorrect combinations, the electric telescopic rod 19 can be controlled to extend a short distance and push fixed boss 20 and movable boss 21 toward connector 23 until movable boss 21 passes the locking block 24. Then, under the action of spring 13, locking pin 12 is pulled, driving... The connecting seat 23 moves away from the electric telescopic rod 19. During this movement, the arc-shaped surfaces of the fixed boss 20 and the movable boss 21, along with the inclined surface of the locking block 24, allow the electric telescopic rod 19 to automatically disengage from the connecting seat 23. This causes the electronic connector 14 to automatically contact the power connector 15, thus establishing a power circuit for the alarm 16 and activating the alarm. When staff need to legally open the Class IV warehouse, they enter the correct password through the combination lock on the surface of the warehouse door 2. The combination lock sends an electrical command to the electric telescopic rod 19 to maintain its retraction. The locking pin 12 remains stationary, and the electronic connector 14 and the power connector 15 remain separated. The power circuit for the alarm 16 remains disconnected. When unauthorized intrusion occurs or an attempt is made to open the warehouse door 2 by repeatedly entering incorrect passwords, the combination lock sends an electrical command to the electric telescopic rod 19 to maintain its retraction. The locking pin 12 remains stationary, and the electronic connector 14 and the power connector 15 remain separated. The power circuit for the alarm 16 remains disconnected. When an unauthorized intrusion occurs or an attempt is made to open the warehouse door 2 by repeatedly entering incorrect passwords, the combination lock sends an electrical command to the electric telescopic rod 19 to maintain its retraction. The telescopic rod 19 sends an electrical command for short-distance extension, causing the output end of the electric telescopic rod 19 to extend short-distance, pushing the fixed boss 20 and the movable boss 21 together towards the connecting seat 23. During the movement, the movable boss 21 will contact the inclined surface of the locking block 24. As the extension force increases, the movable boss 21 presses against the inclined surface of the locking block 24, causing the locking block 24 to retract into the locking groove of the connecting seat 23. At the same time, the spring 26 is compressed, and the positioning slide rod 25 slides along the positioning slide groove to ensure that the retraction direction of the locking block 24 is accurate, until the movable boss 21 completely passes over the locking block 24. The locking block 24 of the connecting seat 23 then contacts the arc-shaped surfaces of the fixed boss 20 and the movable boss 21. Utilizing the guiding effect of the inclined surface and the arc-shaped surface, the electric telescopic rod 19 and the connecting seat 23... Automatic disengagement prevents component jamming. Simultaneously, the combination lock connects the electromagnet 10 to the external power supply circuit. The electromagnet 10 then generates magnetic force, which repels the permanent magnet 9 in the middle of the push frame 8. This pushes the push frame 8, causing the fixed plate 6 to briefly contract the spring 7 to avoid the impact. It also causes the inclined surface of the locking gear 11 to disengage from the inclined surface at the top of the locking pin 12, ensuring that the locking pin 12 smoothly returns to its initial low position. After the movable boss 21 passes the locking block 24, the limiting engagement between the electric telescopic rod 19 and the connecting seat 23 fails. At this time, the tension spring 13 between the locking pin 12 and the four-category storage body 1 releases the elastic force generated by the previous tension, pulling the locking pin 12 quickly back to its initial position along the moving groove of the monitoring seat 5. As the locking pin 12 moves...The electronic connector 14 on the surface of the penetrating end precisely connects with the power connector 15 on the lower surface of the monitoring seat 5. The power circuit between the alarm 16 and the external power supply immediately closes, and the alarm 16 immediately activates and emits an alarm signal, achieving monitoring and early warning of illegal intrusion. At this time, the vault door 2 will be completely closed. Subsequent personnel must use a mechanical key and re-enter the correct password to operate the combination lock to restore the device to its initial warning-ready state before the Class IV vault body 1 can be opened normally. The maintenance door 4 on the back of the Class IV vault body 1, near the monitoring seat 5, slides closed through the storage cavity, protecting the early warning mechanism 3. If subsequent maintenance is required, the maintenance door 4 can be slid open for operation.

[0030] Resetting after unauthorized triggering requires dual verification with a mechanical key and the correct password to prevent unauthorized reset. After the device triggers an alarm, simply entering the correct password is not enough to reset it. Staff must use the mechanical key and re-enter the correct password to restore the initial alarm-ready state. This prevents unauthorized personnel from directly resetting the device and erasing alarm traces after cracking the password, ensuring that only staff with full permissions can handle the alarm after it is triggered. This further enhances the security of unauthorized protection and is suitable for the storage needs of high-value, high-confidentiality items in four types of warehouses.

[0031] Electromagnet 10 is only powered on during illegal operations, reducing energy consumption and losses. In the initial state and during legal operations, electromagnet 10 is in a de-powered state. It is only powered on when an illegal intrusion triggers an alarm, eliminating the need for long-term power supply to maintain its function. This reduces the overall energy consumption of the device, making it suitable for the long-term standby requirements of the four types of warehouses. It also reduces the heating and magnetic decay issues caused by long-term power supply to electromagnet 10, lowering the probability of component wear and further improving the stability and service life of the device.

[0032] The device is easy to maintain without disassembling the main structure, thus reducing maintenance costs. The back of the four-type storage unit 1, near the monitoring seat 5, is designed with an inspection door 4 that slides through the storage cavity. When maintenance, repair, or component replacement of the early warning mechanism 3 is required, it can be operated directly by simply sliding open the inspection door 4. There is no need to disassemble the main structure of the four-type storage unit 1, nor to disassemble the storage door 2, combination lock, or other related components. This greatly reduces the time and labor costs required for maintenance, while avoiding problems such as decreased sealing performance and damage to protective functions caused by disassembling the main structure. This ensures that the device can still maintain its original protective and early warning effects after maintenance.

The permanent magnet (9) is fixed in the middle of the surface of the push frame (8), and the electromagnet (10) is fixed on the surface of the monitoring seat (5). The electromagnet (10) is set opposite to the permanent magnet (9), and the magnetism generated by the electromagnet (10) after being energized is the same as that of the permanent magnet (9), which can generate a repulsive force.

5. The four-category library intrusion monitoring and early warning device according to claim 4, characterized in that: Limiting blocks (17) are symmetrically fixed on both sides of the surface of the locking pin (12). The monitoring seat (5) has a limiting groove that matches the limiting block (17) to limit the movement of the locking pin (12) and prevent the electronic connector (14) from deviating when it is connected to the power connector (15). The back surface of the four types of storage body (1) near the monitoring seat (5) is slidably connected to the maintenance door (4) through the storage cavity, which facilitates the maintenance and repair of the early warning mechanism (3). The alarm (16) is electrically connected to the power connector (15) through a wire. The electronic connector (14) is electrically connected to the external power supply. When the electronic connector (14) contacts the power connector (15), the alarm (16) forms a power circuit and starts the alarm.

6. The four-category library intrusion monitoring and early warning device according to claim 1, characterized in that: A fixed boss (20) is fixed at the output end of the electric telescopic rod (19). A movable boss (21) is slidably connected to the output end surface of the electric telescopic rod (19) at the position corresponding to the fixed boss (20). The movable boss (21) and the fixed boss (20) are arranged symmetrically. A spring array (22) is fixed between the fixed boss (20) and the movable boss (21).

7. The four-category library intrusion monitoring and early warning device according to claim 6, characterized in that: The release mechanism (18) also includes a locking block (24), a positioning slide rod (25), and a spring (26). Two sets of locking blocks (24) are symmetrically slidably connected in the locking grooves opened inside the connecting seat (23). The locking block (24) has a trapezoidal structure and an inclined surface is opened on the side of the locking block (24) facing the electric telescopic rod (19). The positioning slide rod (25) is fixed on one side of the surface of the locking block (24) and is slidably connected in the positioning slide groove opened inside the connecting seat (23). The spring (26) is sleeved on the surface of the positioning slide rod (25) and the two ends of the spring (26) are respectively fixed between the locking block (24) and the connecting seat (23). When the electric telescopic rod (19) extends, the locking block (24) is embedded in the locking groove and compresses the spring (26), thereby realizing a stable connection between the electric telescopic rod (19) and the connecting seat (23).

8. The four-category library intrusion monitoring and early warning device according to claim 7, characterized in that: In the initial state, spring 2 (22) is in the extended state, locking block (24) is between the fixed boss (20) and movable boss (21), and the combination lock is electrically connected to the electric telescopic rod (19). After the correct combination lock is entered, the electric telescopic rod (19) remains in the initial retracted state. The locking connecting seat (23) drives the locking pin (12) to stretch the tension spring (13) and generate elastic force. With the cooperation of the locking gear group (11), the electronic connector (14) and the power connector (15) are separated, and the warning state is released. After the combination lock continuously enters the wrong combination, the electric telescopic rod (19) can be controlled to extend a short distance and push the fixed boss. (20) and the movable boss (21) move closer to the connecting seat (23) until the movable boss (21) passes the locking block (24). Then, under the action of the tension spring (13), the locking pin (12) is pulled to move the connecting seat (23) away from the electric telescopic rod (19). During this period, the arc surface of the fixed boss (20) and the movable boss (21) and the inclined surface of the locking block (24) can make the electric telescopic rod (19) automatically disengage from the connecting seat (23), thereby causing the electronic connector (14) to automatically contact the power connector (15), so that the alarm (16) forms a power circuit and starts the alarm.
