Description

Technical Field

[0001] This invention relates to the field of lock technology, and in particular to a lock body structure. Background Technology

[0002] As a crucial storage container for various tools and equipment, the reliability of the lock structure, ease of operation, and emergency response capability of tool cabinets directly impact safety and efficiency. However, current technology generally lacks an effective emergency unlocking mechanism in the event of a power outage. When a power failure occurs or the electric drive components of the lock malfunction, the cabinet door cannot be unlocked quickly, hindering the retrieval of tools and affecting work progress. Furthermore, the unlocking and locking procedures are cumbersome, often relying on keys or complex button operations, reducing ease of use. Summary of the Invention

[0003] This invention provides a lock body structure that facilitates rapid unlocking even in the event of a power outage or malfunction of the electric components. Unlocking and locking operations can be achieved simply by pressing the tool cabinet door, simplifying the operation process and improving the stability of unlocking and locking.

[0004] This invention provides a lock body structure for use in tool cabinets. The lock body structure includes: a shell, a movable block, a rotating block, an emergency unlocking module, and a first driving component.

[0005] A movable block engages with the locking hook of the tool cabinet door to lock or unlock the door. A rotating block is driven by the movable block to lock or unlock the door. An emergency unlocking module is housed within the housing and includes a push rod and a stop assembly. The push rod is slidably disposed within the housing, with at least a portion protruding from the housing and abutting against one side of the tool cabinet door. At least a portion of the push rod within the housing abuts against the rotating block and pushes the rotating block to engage or disengage from the movable block. The stop assembly is located on the side of the push rod away from the tool cabinet door and has a first state that restricts the movement of the push rod when energized and a second state that avoids the push rod when de-energized. A first driving member is disposed within the housing, and its telescopic end is connected to the rotating block to drive the rotating block to rotate.

[0006] The lock body structure includes an energized unlocking state and a power-off emergency unlocking state. In the energized unlocking state, the first drive member is energized, the stop assembly is in a first state to restrict the movement of the push rod, the telescopic end of the first drive member retracts and drives the rotating block to rotate to separate from the movable block, so that the movable block rotates and separates from the lock hook of the tool cabinet door, thereby unlocking the tool cabinet door. In the power-off emergency unlocking state, the first drive member is de-energized, the telescopic end of the first drive member retracts and drives at least a part of the structure of the stop assembly to move, the stop assembly is in a second state to avoid the push rod, presses on the other side of the tool cabinet door to push the push rod to move axially a preset stroke distance, the push rod pushes the rotating block to rotate to separate from the movable block, so that the movable block rotates and separates from the lock hook of the tool cabinet door, thereby unlocking the tool cabinet door.

[0007] The technical solution of this invention includes an emergency unlocking module comprising a push rod and a stop assembly. At least a portion of the push rod protrudes from the housing and abuts against one side of the tool cabinet door. Pressing the tool cabinet door causes the push rod to slide. At least a portion of the push rod located within the housing abuts against a rotating block, pushing the rotating block to engage or disengage with a movable block, thereby causing the movable block to engage with the locking hook of the tool cabinet door to lock or unlock the door. The stop assembly is located on the side of the push rod away from the tool cabinet door and has a first state that restricts the movement of the push rod when energized and a second state that avoids the push rod when de-energized. In the energized unlocking state, the first drive unit is energized, and the stop assembly is in the first state to restrict the movement of the push rod. The telescopic end of the first drive unit retracts and drives the rotating block to rotate to separate from the movable block, so that the movable block rotates and separates from the lock hook of the tool cabinet door, thereby unlocking the tool cabinet door. In the energized emergency unlocking state, the first drive unit is de-energized, the telescopic end of the first drive unit retracts and drives at least a part of the structure of the stop assembly to move. The stop assembly is in the second state to avoid the push rod, and presses on the other side of the tool cabinet door to push the push rod to move axially along a preset stroke distance. The push rod pushes the rotating block to rotate to separate from the movable block, so that the movable block rotates and separates from the lock hook of the tool cabinet door, thereby unlocking the tool cabinet door. This invention enables remote control unlocking when powered on, meeting the needs of automated management. In an emergency unlocking state during a power outage, the tool cabinet door will not open automatically, but it can be unlocked by directly pressing the door, eliminating the need for additional tools. This solves the unlocking problem during power outages or when electric components malfunction, improving emergency response capabilities. After power is restored, the lock body structure returns to its initial state. Furthermore, it simplifies the operation process. In an emergency unlocking state during a power outage, pressing the tool cabinet door once unlocks it; locking requires simply closing the door and pressing it again. The unlocking process requires no key or complex buttons, lowering the operational threshold and improving ease of use. It also enhances the stability of unlocking and locking.

[0008] According to the aforementioned embodiment of the first aspect of the present invention, the stop assembly includes a second drive member and a stop block. The stop block is located on the side of the push rod away from the tool cabinet door and within the stroke area of ​​the push rod. In a first state, the stop block restricts the movement of the push rod. The telescopic end of the first drive member is connected to the stop block. In a power-off emergency unlocking state, the second drive member is de-energized, the telescopic end of the first drive member retracts, and the stop block moves to switch to the second state to avoid the push rod.

[0009] According to the aforementioned embodiment of the first aspect of the present invention, the push rod includes a first locking member, and the emergency unlocking module further includes a rotating wheel assembly rotatably disposed within the housing. The outer peripheral surface of the rotating wheel assembly is provided with a first mating area that mates with the first locking member and a second mating area that mates with the rotating block. In the power-off emergency unlocking state, the push rod pushes the rotating block to rotate, the first locking member is located within the first mating area and pushes the rotating wheel assembly to rotate. After the push rod moves a preset stroke distance axially, the first locking member moves away from the first mating area, and the rotating block moves away from the second mating area to restrict the rotation of the rotating block and the rotating wheel assembly. After the pressure on the tool cabinet door is released, the rotating block remains separated from the movable block.

[0010] According to the aforementioned embodiment of the first aspect of the present invention, the rotary wheel assembly includes a first rotary wheel and a second rotary wheel coaxially connected. A plurality of first pawls are evenly spaced on the outer peripheral wall of the first rotary wheel, with a first mating area located between two adjacent first pawls. The push rod also has a protruding first pushing part located on one side of the first locking member, used to push the rotating block to rotate. The housing also includes a second locking member, located within different first mating areas from the first locking member. After the pressure on the tool cabinet door is released, the push rod resets under the elastic action of the first elastic member, and the second locking member restricts the first rotary wheel from reversing. A plurality of second pawls are evenly spaced on the outer peripheral wall of the second rotary wheel, with a second mating area located between two adjacent second pawls. The technical solution of the present invention, by setting a rotary wheel assembly, has a first mating area on the outer peripheral surface that mates with the first locking member and a second mating area that mates with the rotating block, and a housing also includes a second locking member located within different first mating areas from the first locking member. The cooperation between the rotating wheel assembly and the first and second locking components enables the unidirectional rotation and limiting of the rotating block, preventing reset failure after unlocking.

[0011] According to the aforementioned embodiment of the first aspect of the present invention, the push rod is further provided with a second elastic element that is elastically connected to the first locking member. After the pressure on the tool cabinet door is released, the push rod returns to its original position, the first locking member moves away from the first mating area, and drives the second elastic element to move. The second elastic element provides an elastic restoring force for the first locking member. The technical solution of the present invention, by providing the second elastic element, ensures smooth operation of the first locking member, reduces mechanical wear, and extends the service life of the lock body structure.

[0012] According to the aforementioned embodiment of the first aspect of the present invention, the housing is further provided with a third elastic member that is elastically connected to the second locking member. When the first rotating wheel rotates, the third elastic member is squeezed, and the third elastic member provides pressure to lock the second locking member in any of the first mating areas.

[0013] According to any of the foregoing embodiments of the first aspect of the present invention, a torsion spring elastically connected to the movable block is further provided inside the housing. When the rotating block separates from the movable block, the torsion spring provides an elastic restoring force to the movable block, causing the movable block to separate from the locking hook of the tool cabinet door. The technical solution of the present invention, by providing a torsion spring that provides an elastic restoring force to the movable block, ensures smooth movement of the movable block, reduces mechanical wear, and extends its service life.

[0014] According to any of the foregoing embodiments of the first aspect of the present invention, a fourth elastic member is further provided between the telescopic end of the second driving member and the stop block, and the fourth elastic member provides an elastic restoring force for the stop block.

[0015] According to any of the foregoing embodiments of the first aspect of the present invention, the rotating block includes a rotating shaft, a first portion and a second portion located on opposite sides of the rotating shaft. In the power-off emergency unlocking state, the first pushing part pushes the first portion to rotate along the rotating shaft. In the power-on unlocking state, the telescopic end of the first driving member drives the second portion to rotate along the rotating shaft.

[0016] According to the foregoing embodiment of the first aspect of the present invention, the lock body structure further includes a lock body state detection component. The lock body state detection component is disposed within the housing and electrically connected to the first driving member. The lock body state detection component includes a first trigger and a second trigger. When the lock body structure is in the unlocked state, the second part rotates by a preset angle and triggers the first trigger, providing a "lock body unlocked" signal. When the lock body structure is in the locked state, the second part rotates by a preset angle and triggers the second trigger, providing a "lock body locked" signal. The technical solution of the present invention, through the lock body state detection component, provides real-time feedback on the lock body's locking and unlocking states, providing data support for remote monitoring and fault diagnosis.

[0017] According to the aforementioned embodiment of the first aspect of the present invention, a second pushing part and a third pushing part are sequentially spaced apart on the pushing rod, and the second pushing part and the third pushing part are disposed on the same side as the first pushing part. The lock body structure also includes a tool cabinet door status detection component, which is disposed within the housing and electrically connected to the first driving member. The tool cabinet door status detection component includes a third trigger and a fourth trigger. When the tool cabinet door is in the closed state, the second pushing part triggers the third trigger, feeding back a "tool cabinet door closed" signal. When the tool cabinet door is in the open state, the third pushing part triggers the fourth trigger, feeding back a "tool cabinet door open" signal to prevent the first driving member from being energized. The technical solution of the present invention, by setting a tool cabinet door status detection component, provides real-time feedback on the unlocking and locking status of the tool cabinet door, and at the same time, prevents the first driving member from being energized when the tool cabinet door is open by using the fourth trigger, avoiding false triggering, thereby improving the stability of unlocking and locking.

[0018] This invention's technical solution adapts to various scenarios through dual unlocking modes. Power-on unlocking enables remote control, meeting automation management needs. Emergency unlocking during power outages requires no additional tools; simply pressing the tool cabinet door completes the unlocking, solving the unlocking problem during power outages or electric component malfunctions and improving emergency response capabilities. Furthermore, it simplifies the locking and unlocking process; locking only requires closing the tool cabinet door and pressing lightly, while unlocking requires no key or complex buttons, lowering the operational threshold and improving ease of use. The rotating block's unidirectional rotation and limiting are achieved through the cooperation of the rotating wheel assembly with the first and second locking components, ensuring stable and reliable structural cooperation and preventing reset failure after unlocking. Multiple elastic elements ensure smooth operation of each component, reducing mechanical wear and extending the lock body's lifespan. The lock body status detection component and the tool cabinet door status detection component provide comprehensive, accurate, and real-time feedback on the lock body's locking / unlocking status and the tool cabinet door's open / closed status, providing data support for remote monitoring and fault diagnosis. Simultaneously, a fourth trigger element prevents the drive component from being energized when the tool cabinet door is opened, avoiding accidental triggering. The internal structure of the shell is compact and highly versatile, adaptable to tool cabinets of different specifications, and each component is assembled in a modular fashion, which facilitates production and subsequent maintenance.

Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0026] This invention provides a lock body structure that facilitates rapid unlocking even in the event of a power outage or malfunction of the electric components. Unlocking and locking operations can be achieved simply by pressing the tool cabinet door, simplifying the operation process and improving the stability of unlocking and locking.

[0027] like Figures 1 to 2 As shown, an embodiment of the present invention provides a lock body structure 100, which is applied to a tool cabinet 200. The lock body structure 100 includes: a housing 110, a movable block 120, a rotating block 130, an emergency unlocking module 140, and a first driving component 150.

[0028] like Figures 1 to 2As shown, the housing 110 is the outer shell of the lock body structure 100, and all parts are fixedly assembled inside and used to protect the parts, and is closed by the cover plate 114.

[0029] like Figures 1 to 2 As shown, the movable block 120 is used to cooperate with the locking hook 211 of the tool cabinet door 210 to lock or unlock the tool cabinet door 210. The rotating block 130 is drivenly connected to the movable block 120 to drive the movable block 120 to lock or unlock the tool cabinet door 210.

[0030] like Figures 1 to 2 As shown, the emergency unlocking module 140 is disposed within the housing 110. The emergency unlocking module 140 includes a push rod 141 and a stop assembly 142. The push rod 141 is slidably disposed within the housing 110. A portion of the push rod 141 protrudes from the housing 110 and abuts against one side of the tool cabinet door 210. The portion of the push rod 141 located within the housing 110 abuts against the rotating block 130 and pushes the rotating block 130 to engage or disengage from the movable block 120.

[0031] like Figures 1 to 2 As shown, the stop assembly 142 is located on the side of the push rod 141 away from the tool cabinet door 210, and has a first state that can restrict the movement of the push rod 141 when the power is on and a second state that avoids the push rod 141 when the power is off.

[0032] like Figures 1 to 2 As shown, the first driving member 150 is disposed inside the housing 110, and the telescopic end of the first driving member 150 is connected to the rotating block 130 to drive the rotating block 130 to rotate.

[0033] The lock body structure 100 includes an energized unlocking state and an emergency unlocking state when the power is off. Initially, the tool cabinet door 210 is in the closed state.

[0034] like Figures 3 to 4 As shown, in the energized unlocked state, the backend system sends an unlock command, energizing the first drive component 150. The stop assembly 142 is in its first state to restrict the movement of the push rod 141. The telescopic end of the first drive component 150 retracts, causing the rotating block 130 to rotate and separate from the movable block 120. Under the elastic action of the torsion spring, the movable block 120 rebounds and pushes open the rotating block 130, causing the movable block 120 to rotate and separate from the locking hook 211 of the tool cabinet door 210. At the same time, the push rod 141 releases and pushes open the tool cabinet door 210 to unlock it. Simultaneously, the stop assembly 142 is in its first state, which can limit the travel of the push rod 141 and prevent accidental manual contact that could cause instability or damage to the mechanism. To lock, simply press the tool cabinet door 210 once to close it.

[0035] like Figures 5 to 9As shown, in the emergency unlocking state after a power outage, the first drive component 150 is de-energized, and the telescopic end of the first drive component 150 retracts, causing at least a portion of the stop assembly 142 to move. The stop assembly 142 is in a second state to avoid the push rod 141, thus increasing the travel distance of the push rod 141. Pressing the other side of the tool cabinet door 210 pushes the push rod 141 to move axially a preset distance. The push rod 141 pushes the rotating block 130 to rotate and separate from the movable block 120, causing the movable block 120 to rotate and separate from the locking hook 211 of the tool cabinet door 210, thereby unlocking the tool cabinet door 210. When locking, simply closing the tool cabinet door 210 by pressing it down will complete the closing process.

[0036] The technical solution of this invention includes an emergency unlocking module 140, which comprises a push rod 141 and a stop assembly 142. At least a portion of the push rod 141 protrudes from the housing 110 and abuts against one side of the tool cabinet door 210. Pressing the tool cabinet door 210 causes the push rod 141 to slide. At least a portion of the push rod 141 located within the housing 110 abuts against the rotating block 130 and pushes the rotating block 130 to engage or disengage with the movable block 120, thereby causing the movable block 120 to engage with the locking hook 211 of the tool cabinet door 210 to lock or unlock the tool cabinet door 210. The stop assembly 142 restricts the movement of the push rod 141 when energized and avoids the push rod 141 when de-energized. In the energized unlocking state, the first drive member 150 is energized, and the stop assembly 142 is in a first state to restrict the movement of the push rod 141. The telescopic end of the first drive member 150 retracts and drives the rotating block 130 to rotate and separate from the movable block 120, so that the movable block 120 rotates and separates from the locking hook 211 of the tool cabinet door 210, thereby unlocking the tool cabinet door 210. In the energized emergency unlocking state, the first drive member 150 is de-energized, and the telescopic end of the first drive member 150 retracts and drives at least a portion of the structure of the stop assembly 142 to move. The stop assembly 142 is in a second state to avoid the push rod 141, and presses the other side of the tool cabinet door 210 to push the push rod 141 to move axially a preset stroke distance. The push rod 141 pushes the rotating block 130 to rotate and separate from the movable block 120, so that the movable block 120 rotates and separates from the locking hook 211 of the tool cabinet door 210, thereby unlocking the tool cabinet door 210.

[0037] This invention enables remote control unlocking when powered on, meeting the needs of automated management. In an emergency unlocking state during a power outage, the tool cabinet door 210 will not open automatically, but can be unlocked by directly pressing the door 210 without the need for additional tools. This solves the unlocking problem during power outages or when electric components malfunction, improving emergency response capabilities. After power is restored, the lock body structure 100 returns to its initial state. Furthermore, it simplifies the operation process. In an emergency unlocking state during a power outage, pressing the tool cabinet door 210 once unlocks it; locking requires only closing the door 210 and pressing it again. The unlocking process does not require a key or complex buttons, lowering the operational threshold and improving ease of use. It also enhances the stability of unlocking and locking.

[0038] The spatial arrangement of the stop assembly 142 and the push rod 141 in the technical solution of this invention ensures that the push rod 141 is in a safe and restricted state when the power is on for unlocking, preventing mechanical damage caused by human error. Furthermore, it allows for complete release during emergency unlocking in case of power failure, balancing safety and emergency preparedness. This technical solution enables emergency door opening without altering the appearance of the tool cabinet door 210 or user operating habits.

[0039] Preferably, the housing 110 has multiple mounting bases inside for assembling the board module 180, coils, and mechanical parts. The side wall of the housing 110 has guide holes for mounting the push rod 141, and one side of the housing 110 has an exposed section of the push rod 141, allowing the user to press this exposed section when the tool cabinet door 210 is closed. The inner wall of the guide hole is provided with a wear-resistant bushing to reduce wear on the push rod 141 during sliding. The cover plate 114 is removable for maintenance. A light guide post 115 or an indicator window is also provided on the housing to cooperate with external indicator lights to display the working status of the internal components.

[0040] like Figures 5 to 7 As shown, the stop assembly 142 includes a second drive member 1421 and a stop block 1422. The stop block 1422 is located on the side of the push rod 141 away from the tool cabinet door 210 and within the stroke area of ​​the push rod 141. The second drive member 1421 drives the stop block 1422 to slide within a small stroke perpendicular to the axis of the push rod 141 via its telescopic end. In the first state, the stop block 1422 is in physical contact or abuts against the push end of the push rod 141, thereby limiting the maximum axial displacement of the push rod 141.

[0041] like Figures 7 to 8As shown, the telescopic end of the first drive member 150 is connected to the stop block 1422. In the emergency unlocking state after power failure, the second drive member 1421 is de-energized, the telescopic end of the first drive member 150 retracts and drives the stop block 1422 to move to the second state to avoid the push rod 141. After power is restored, the second drive member 1421 is energized and pushes the stop block 1422. The stop block 1422 returns to the first state that restricts the movement of the push rod 141, thus blocking the movement of the push rod 141 and releasing the emergency unlocking state. Pressing the tool cabinet door 210 again will prevent the door from opening.

[0042] Preferably, both the first driving component 150 and the second driving component 1421 are electromagnetic solenoids, which have short extension and retraction strokes and fast response speeds to ensure that the unlocking action is fast and stable.

[0043] like Figures 7 to 8 As shown, the push rod 141 includes a first locking member 143, and the emergency unlocking module 140 also includes a rotating wheel assembly 144 rotatably disposed within the housing 110, as shown. Figures 10 to 11 As shown, the outer peripheral surface of the rotary wheel assembly 144 is provided with a first mating area 1441 that mates with the first locking member 143 and a second mating area 1442 that mates with the rotating block 130.

[0044] like Figure 9 As shown, in the emergency unlocking state after power failure, the push rod 141 pushes the rotating block 130 to rotate, the first locking member 143 is located in the first mating area 1441 and pushes the rotating wheel assembly 144 to rotate. After the push rod 141 moves a preset travel distance along the axial direction, the first locking member 143 moves away from the first mating area 1441, and the rotating block 130 moves away from the second mating area 1442 to limit the rotation of the rotating block 130 and the rotating wheel assembly 144. After the pressure on the tool cabinet door 210 is released, the rotating block 130 remains separated from the movable block 120.

[0045] like Figures 10 to 11 As shown, the rotating wheel assembly 144 includes a first rotating wheel 1443 and a second rotating wheel 1444 coaxially connected. The outer peripheral wall of the first rotating wheel 1443 is provided with a plurality of first pawls C1 spaced evenly at intervals, and a first mating area 1441 is located between two adjacent first pawls C1. The push rod 141 also has a protruding first pushing part 145, located on one side of the first locking member 143, which is used to push the rotating block 130 to rotate. Specifically, when the push rod 141 moves axially, the first locking member 143 pushes the first mating area 1441, thereby achieving a step-by-step push on the first rotating wheel 1443.

[0046] In some embodiments, the central angle between two adjacent first pawls C1 is 30°-45°. Specifically, in this embodiment, the rotating wheel assembly 144 can only rotate in one direction. A first pawl C1 is provided on the first rotating wheel 1443 every 30°, and then a first mating area 1441 is provided every 30°, and then a first pawl C1 is provided every 30° again. This arrangement is repeated and alternately set. The first locking member 143 on the push rod 141 pushes the first rotating wheel 1443 to rotate only 30 degrees each time.

[0047] like Figure 9 As shown, the housing 110 also includes a second locking member 111. The second locking member 111 and the first locking member 143 are located in different first mating areas 1441. After the pressure on the tool cabinet door 210 is released, the push rod 141 is reset under the elastic action of the first elastic member 146. The second locking member 111 is used to restrict the first rotating wheel 1443 from reversing. A plurality of second pawls C2 are evenly spaced on the outer peripheral wall of the second rotating wheel 1444. The second mating area 1442 is located between two adjacent second pawls C2. Specifically, the first elastic member 146 is a spring.

[0048] The technical solution of this invention involves setting up a rotating wheel assembly 144. The outer peripheral surface of the rotating wheel assembly 144 has a first mating area 1441 that mates with the first locking member 143 and a second mating area 1442 that mates with the rotating block 130. The housing 110 also includes a second locking member 111, which is located in different first mating areas 1441 from the first locking member 143. The first locking member 143 pushes the first rotating wheel 1443 to rotate step by step, while the second locking member 111 enters the meshing position of the second mating area 1442 after stepping to restrict the second rotating wheel 1444 from reversing. The cooperation between the rotating wheel assembly 144 and the first locking member 143 and the second locking member 111 realizes the unidirectional rotation and limiting of the rotating block 130, ensuring that the rotating wheel assembly 144 will be locked in a safe position after the user manually presses the tool cabinet door 210, avoiding reset failure after unlocking.

[0049] like Figure 9 As shown, in the emergency unlocking state during a power outage, pressing the tool cabinet door 210 moves the push rod 141. When the push rod 141 moves a preset distance to its end point, the rotating block 130 is blocked by the second pawl C2 and cannot spring back. The rotating block 130 remains in the position separated from the movable block 120 to prevent springback from causing re-locking. After releasing the hand, the movable block 120 and the push rod 141 pop out simultaneously and push open the tool cabinet door 210 to complete the unlocking. After power is restored, the control logic and the second drive unit 1421 return to their normal positions.

[0050] This application establishes a short-stroke check-back loop mechanism by setting a push rod 141 and a rotating wheel assembly 144. This achieves a cyclic control characteristic of "unlocking the tool cabinet door 210 by pressing it once and locking it by pressing it again." The push rod 141 locks immediately after reaching its maximum stroke, and the rotating wheel assembly 144 immediately prevents the push rod 141 from rebounding. The short stroke from the trigger mechanism to the rebound prevention (e.g., a check-back allowance of approximately 1 mm) helps ensure that the door will not relock due to rebound after release, guaranteeing the reliability of the single action and subsequent repeatability, thus improving user experience and safety. After power is restored, the door can be automatically or controlled to reset to the initial electrically controlled locked state.

[0051] like Figures 7 to 8 As shown, the push rod 141 is also provided with a second elastic element 147 that is elastically connected to the first locking member 143. After the pressure on the tool cabinet door 210 is released, the push rod 141 returns to its original position, the first locking member 143 moves away from the first mating area 1441, and drives the second elastic element 147 to move. The second elastic element 147 provides an elastic restoring force for the first locking member 143. The technical solution of this invention, by setting the second elastic element 147, ensures smooth operation of the first locking member 143, reduces mechanical wear, and extends the service life of the lock body structure 100. Specifically, the second elastic element 147 is a spring sheet.

[0052] like Figures 7 to 8 As shown, the housing 110 also includes a third elastic element 112 that is elastically connected to the second locking member 111. When the first rotating wheel 1443 rotates, it compresses the third elastic element 112, providing pressure to lock the second locking member 111 into any of the first mating areas 1441. Specifically, the third elastic element 112 is a spring.

[0053] like Figure 9 As shown, the housing 110 also includes a torsion spring 113 elastically connected to the movable block 120. When the movable block 120 engages with the rotating block 130, the torsion spring 113 is stretched. When the rotating block 130 separates from the movable block 120, the torsion spring 113 provides an elastic restoring force to the movable block 120, thereby causing the movable block 120 to separate from the locking hook 211 of the tool cabinet door 210. The technical solution of this invention, by providing the torsion spring 113, ensures smooth operation of the movable block 120, reduces mechanical wear, and extends its service life by providing an elastic restoring force to the movable block 120.

[0054] like Figure 9As shown, a fourth elastic element 148 is also provided between the telescopic end of the second driving member 1421 and the stop block 1422. The fourth elastic element 148 provides an elastic restoring force for the stop block 1422. When the power is off, the stop block 1422 switches to the second state under the action of the fourth elastic element 148 to avoid the push rod 141, allowing the push rod 141 to obtain a travel distance to implement emergency unlocking. The relative position of the stop block 1422 and the push rod 141, the travel distance of the stop block 1422, and the spring stiffness should be matched so that when the power is on, the push rod 141 only performs a safe normal operating travel distance, while when the power is off, it can obtain sufficient travel to drive the rotating wheel assembly 144 and the rotating block 130 to complete the unlocking action.

[0055] like Figures 3 to 8 As shown, the rotating block 130 includes a rotating shaft 131, a first part 132 and a second part 133 located on opposite sides of the rotating shaft 131. In the power-off emergency unlocking state, the first pushing part 145 pushes the first part 132 to rotate along the rotating shaft 131. In the power-on unlocking state, the telescopic end of the first driving member 150 drives the second part 133 to rotate along the rotating shaft 131.

[0056] Specifically, the first part 132 of the rotating block 130 is provided with a locking end 134 for hooking onto or separating from the movable block 120. The second part 133 of the rotating block 130 is connected to the telescopic end of the first drive member 150 (which can be connected via a connecting rod or a pin), and the first part 132 cooperates with the rotating wheel assembly 144 to receive the mechanical push of the push rod 141, thereby realizing the functional division of electric and manual drive modes.

[0057] like Figure 2 As shown, the lock body structure 100 also includes a lock body state detection component 160. The lock body state detection component 160 is disposed within the housing 110 and electrically connected to the first driving member 150. The lock body state detection component 160 includes a first trigger 161 and a second trigger 162. When the lock body structure 100 is in the unlocked state, the second part 133 rotates a preset angle and triggers the first trigger 161, providing a "lock body unlocked" signal. When the lock body structure 100 is in the locked state, the second part 133 rotates a preset angle and triggers the second trigger 162, providing a "lock body locked" signal. Specifically, both the first trigger 161 and the second trigger 162 are microswitches. This invention's technical solution, through the lock body state detection component 160, provides real-time feedback on the lock body's locking and unlocking states, offering data support for remote monitoring and fault diagnosis.

[0058] like Figures 3 to 8 As shown, a second pushing part 149 and a third pushing part 1410 are also provided on the pushing rod 141 in sequence at intervals, and the second pushing part 149 and the third pushing part 1410 are located on the same side of the first pushing part 145.

[0059] like Figure 2 As shown, the lock body structure 100 also includes a tool cabinet door status detection component 170, which is disposed within the housing 110 and electrically connected to the first drive member 150. The tool cabinet door status detection component 170 includes a third trigger member 171 and a fourth trigger member 172. When the tool cabinet door 210 is in the closed state, the second push part 149 triggers the third trigger member 171, feeding back a "tool cabinet door 210 closed" signal. When the tool cabinet door 210 is in the open state, the third push part 1410 triggers the fourth trigger member 172, feeding back a "tool cabinet door 210 open" signal to prevent the first drive member 150 from being energized. Specifically, both the third trigger member 171 and the fourth trigger member 172 are tactile switches.

[0060] The technical solution of this invention improves the stability of unlocking and locking by setting up a tool cabinet door status detection component 170 to provide real-time feedback on the locking and unlocking status of the tool cabinet door 210. Simultaneously, a fourth trigger 172 prevents the first drive component 150 from being energized when the tool cabinet door 210 is open, avoiding false triggering. At least two microswitches and two tactile switches are installed inside the housing 110 to provide feedback on the locking and unlocking status of the lock body, and to provide real-time feedback on the locking and unlocking status of the tool cabinet door 210. These switches also prevent abnormal detection of prolonged energization of the second drive component 1421. The feedback signals are read by the board module 180, which determines the power-on logic of the first drive component 150 and the second drive component 1421, thereby achieving coil excitation time limitation and safety protection. The combination of the lock body status detection component 160, the cabinet door status detection component, and the board module 180 makes this application not only a purely mechanical emergency pressing solution, but also an electromechanical integrated intelligent lock body: when powered on, it can work according to the authorized logic in the background, and when powered off, it retains an emergency channel that is not electrically operable but manually operable, thus taking into account both intelligence and security.

[0061] This invention's technical solution adapts to various scenarios through dual unlocking modes. Power-on unlocking enables remote control, meeting automation management needs. Emergency unlocking during power outages requires no additional tools; simply pressing the tool cabinet door 210 completes the unlocking process, solving the unlocking problem during power outages or electric component malfunctions and improving emergency response capabilities. Furthermore, it simplifies the locking and unlocking process; locking only requires closing the tool cabinet door 210 and pressing lightly, eliminating the need for keys or complex buttons, lowering the operational threshold and improving ease of use. The unidirectional rotation and limiting of the rotating block 130 are achieved through the cooperation of the rotating wheel assembly 144 with the first locking component 143 and the second locking component 111, ensuring a stable and reliable structure and preventing reset failure after unlocking. Multiple elastic elements ensure smooth operation of each component, reducing mechanical wear and extending the lock body's service life. The lock body status detection component 160 and the tool cabinet door status detection component 170 provide comprehensive, accurate, and real-time feedback on the lock body's locking or unlocking status and the tool cabinet door 210's opening and closing status, providing data support for remote monitoring and fault diagnosis. Simultaneously, the fourth trigger component 172 prevents the drive component from being energized when the tool cabinet door 210 is open, avoiding false triggering. The housing 110 has a compact internal structure design, high versatility, and can be adapted to tool cabinets 200 of different specifications. Furthermore, the modular assembly of each component facilitates manufacturing and subsequent maintenance.
