[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0038] Furthermore, in this utility model, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0039] This utility model proposes a low-pressure drawer cabinet handle lock, referring to... Figure 1 and Figure 2 The low-voltage drawer cabinet handle lock includes a fixing component 1, a handle component 2, and an electrical lock structure 3. The fixing component 1 is fixed to the drawer cabinet door, the handle component 2 is rotatably connected to the fixing component 1, and the electrical lock structure 3 is located inside the handle component 2 and rotates synchronously with it. The electrical lock structure 3 includes a drive component 4 and a locking component 5. The drive component 4 includes an electronic control board (not shown in the figure), which receives unlocking or locking commands from an external terminal device and controls the drive component 4 to operate according to the unlocking or locking commands.

[0040] The locking assembly 5 has an unlocked state of the unlocking handle assembly 2 and a locked state of the locking handle assembly 2. The driving assembly 4 is used to drive the locking assembly 5 to switch between the unlocked state and the locked state. In the locked state, the driving assembly 4 drives the locking assembly 5 to lock and connect with the fixed assembly 1. In the unlocked state, the driving assembly 4 drives the locking assembly 5 to release the lock from the fixed assembly 1. When the handle assembly 2 is subjected to external force, it can drive the electric lock structure 3 to rotate relative to the fixed assembly 1, so that the electric lock structure 3 controls the opening or closing of the circuit breaker in the drawer cabinet.

[0041] Based on the above scheme, intelligent control of locking and unlocking is achieved through drive component 4 and locking component 5. This allows for control over the locking and unlocking process of the low-voltage drawer cabinet handle lock, effectively preventing operators from accidentally opening or closing it. This significantly improves the safety of using the low-voltage drawer cabinet handle lock, greatly reducing the occurrence of safety accidents. Moreover, there is no need to lock the handle 21 with an external padlock; the electrical unlocking process is highly efficient. The control board can also monitor the locking and unlocking status of the low-voltage drawer cabinet handle lock in real time, thereby detecting the opening and closing status of the circuit breaker inside the drawer cabinet. This facilitates systematic management and monitoring, thus improving the performance of the low-voltage drawer cabinet handle lock.

[0042] When unlocking the handle lock of the low-voltage drawer cabinet, the operator sends an unlocking command through an external terminal device. The control board receives the unlocking command and controls the drive component 4 to operate. The drive component 4 drives the locking component 5 to release from the locking component 1, thereby unlocking the handle component 2. In the unlocked state, the operator can rotate the handle component 2. During the rotation of the handle component 2, the electrical lock structure 3 is simultaneously rotated, enabling the electrical lock structure 3 to control the opening or closing of the circuit breaker inside the drawer cabinet.

[0043] When locking the handle lock of the low-voltage drawer cabinet, the operator sends a locking command through an external terminal device. The control board receives the locking command and controls the drive component 4 to work. The drive component 4 drives the locking component 5 to lock and connect with the fixed component 1, thereby completing the locking of the handle component 2.

[0044] Furthermore, the control board can also store and record the operation process of the low-voltage drawer cabinet handle lock. On the one hand, it can ensure the safety of the low-voltage drawer cabinet handle lock's locking and unlocking process and monitor the operation of the low-voltage drawer cabinet handle lock being accidentally opened or closed. On the other hand, it can provide operation data support for subsequent maintenance, making it convenient for problem diagnosis and troubleshooting.

[0045] Reference Figures 1 to 6 The low-voltage drawer handle lock also includes a battery 6, which is located inside the handle assembly 2 and electrically connected to the electronic control board. The drive assembly 4 also includes an electric lock cylinder 42, with the electronic control board located inside the electric lock cylinder 42. The battery 6 provides power to the electric lock cylinder 42. The battery 6 provides the power base, enabling the electric lock cylinder 42 to operate in a controlled manner, thus improving the efficiency of locking and unlocking operations.

[0046] Specifically, the handle assembly 2 includes a handle 21, which comprises a handle body 211 and a mounting body 212. The handle body 211 and the mounting body 212 are integrally formed, and the electric lock structure 3 is installed inside the mounting body 212. The handle body 211 has a mounting groove, in which the battery 6 is installed. The mounting groove is covered by a battery cover, making the handle assembly 2 aesthetically pleasing and easy to use. The battery cover is snapped onto the handle body 211 or fixed with screws, making disassembly and assembly convenient and facilitating battery replacement, thus improving the user experience.

[0047] The control board has a wireless communication module that communicates with an external terminal device. When locked, the wireless communication module is disconnected. The handle assembly 2 includes a wake-up button 23, which is used to wake up the wireless communication module.

[0048] When unlocking the low-pressure drawer cabinet handle lock, the operator operates the wake-up button 23 to power on the wireless communication module. External terminal devices can then connect to the wireless communication module, enabling them to control the electric lock cylinder 42 via the electronic control board.

[0049] The wireless communication module may include a Bluetooth wireless communication module, a WIFI wired communication module, etc. In this embodiment, the wireless communication module adopts a Bluetooth wireless communication module. Operators can connect to the Bluetooth wireless communication module via Bluetooth through external terminal devices such as mobile phones, so as to perform intelligent control on site and improve the convenience of on-site operations.

[0050] The handle assembly 2 also includes a cover 22, a mounting body 212 forming a mounting cavity 2121, an electric lock structure 3 disposed within the mounting cavity 2121, and an electric lock cylinder 42 partially exposed in the opening of the mounting cavity 2121. The cover 22 is rotatably connected to the handle body 211 and covers the opening of the mounting cavity 2121. The cover 22 is used to open or close the opening of the mounting cavity 2121. A wake-up button 23 is located on the exposed side of the cover 22, making it convenient for the operator to operate the wake-up button 23.

[0051] Furthermore, when a circuit breaker trips inside a drawer cabinet, the location of the tripped drawer cabinet can be determined via the control board. This greatly reduces the cost of manual positioning and improves intelligent operation.

[0052] Continue to refer to Figures 1 to 6The drive assembly 4 includes a mounting component 41, an electric lock cylinder 42, an active component 43, and a driven component 44. The electric lock cylinder 42 includes a motor (not shown) electrically connected to the electronic control board. Both the active component 43 and the driven component 44 are rotatably mounted within the mounting component 41. The motor is connected to the active component 43 to drive its rotation, and the driven component 44 is drively connected to the active component 43. The locking assembly 5 is movably connected to the mounting component 41. The driven component 44 has an unlocked position and a locked position. The motor drives the driven component 43 to switch between the unlocked and locked positions. In the locked position, the driven component 44 locks the locking assembly 5 to the fixed component 1, placing the handle assembly 2 in a locked state. In the unlocked position, the driven component 44 releases the locking assembly 5 from the fixed component 1, allowing the handle assembly 2 to rotate relative to the fixed component 1.

[0053] With this configuration, the motor can only operate after receiving an unlocking or locking command. This prevents operators from manually operating the low-voltage drawer handle lock in non-emergency situations, thus preventing accidental opening or closing of the low-voltage drawer handle lock and greatly reducing the occurrence of safety accidents.

[0054] Mounting component 41 includes a mounting base 411 and an adapter plate 412. The mounting base 411 has a mounting groove 4111 on the side facing the electric lock cylinder 42. The mounting groove 4111 is elongated, and both the driving member 43 and the driven member 44 are rotatably disposed within it, distributed along the length of the groove. The adapter plate 412 is fixedly connected to the mounting base 411 by screws and covers the portion of the mounting groove 4111 corresponding to the driven member 44. Both sides of the driven member 44 can be rotatably connected to the bottom of the mounting groove 4111 and the adapter plate 412 respectively via convex shafts. The adapter plate 412 has a mounting notch 4121 through which the electric lock cylinder 42 passes, allowing it to connect with the driving member 43. The driving component 43 is exposed in the mounting notch 4121. The motor is connected to the driving component 43 through a connecting shaft. The cross-section of the connecting shaft is set in the form of a square, rectangle, triangle, pentagon, hexagon, etc. The driving component 43 is provided with a socket for the connecting shaft to be inserted. The shape of the socket is adapted to the shape of the connecting shaft.

[0055] The number of locking components 5 includes two, which are arranged on both sides of the driving member 43. The number of driven members 44 includes two, which are arranged on both sides of the driving member 43 and are both connected to the driving member 43 in a transmission manner. The two driven members 44 rotate in the same direction, and the two driven members 44 are arranged in a one-to-one correspondence with the two locking components 5.

[0056] The locking stability of the handle assembly 2 is enhanced by the two locking components 5 and the two driven members 44, thereby improving the reliability of the low-pressure drawer cabinet handle lock. Furthermore, during the rotation of the handle assembly 2, it prevents wobbling or loosening, providing a stable operating feel.

[0057] Mounting member 41 is provided with mounting hole 413, and locking component 5 is movably disposed in mounting hole 413. Driven member 44 is provided with stop part 441 and unlocking notch 442. In the locked position, stop part 441 rotates to mounting hole 413 and restricts locking component 5 from extending out of mounting hole 413. In the unlocked position, unlocking notch 442 rotates to mounting hole 413 and communicates with mounting hole 413 to release the restriction on movement of locking component 5.

[0058] Both the driving member 43 and the driven member 44 are gear structures. The driving member 43 is a circular gear, and the driven member 44 is a cam gear. The circular gear and the cam gear are meshed together. The driven member 44 is arc-shaped. A stop 441 is formed at the end of the driven member 44 away from the driving member 43. An unlocking notch 442 is formed on the side of the driven member 44 away from the engagement with the driving member 43. The unlocking notch 442 can be fan-shaped or arc-shaped.

[0059] Understandably, there are two mounting holes 413 for the installation of two locking components 5.

[0060] Continue to refer to Figures 1 to 6 The locking assembly 5 includes a locking member 51. The mounting member 41 has a mounting hole 413. The locking member 51 is disposed within the mounting hole 413, with one end forming a locking end 511 and the other end forming an abutment end 512. In the locked position, the locking end 511 is used for locking connection with the fixed assembly 1, and the abutment end 512 abuts against the driven member 44. In the unlocked position, the locking end 511 can rotate relative to the fixed assembly 1, and the abutment end 512 can extend out of the mounting hole 413. The fixed assembly 1 has a locking groove 1211, which engages with the locking end 511 in a stop-fitting manner.

[0061] The locking end 511 is spherically shaped, which ensures that it can be locked with the fixed component 1, while also facilitating the rotation of the handle component 2, improving the smoothness of the rotation of the handle component 2, and improving the locking and unlocking efficiency of the low-pressure drawer cabinet handle lock.

[0062] The locking assembly 5 also includes an elastic element 52, which is disposed in the mounting hole 413 and sleeved on the outside of the locking member 51. The mounting hole 413 is a stepped hole, and the outer peripheral wall of the locking member 51 has a stepped portion. One end of the elastic element 52 abuts against the inner wall of the mounting hole 413, and the other end abuts against the stepped portion. In the unlocked or locked state, the locking member 51 elastically abuts against the fixing assembly 1 under the action of the elastic element 52.

[0063] When unlocking the low-pressure drawer cabinet handle lock, the operator sends an unlocking command through an external terminal device. The electronic control board receives the unlocking command and controls the motor to work. The motor rotates forward and drives the driving component 43 to rotate. The rotation of the driving component 43 drives the driven component 44 to rotate, so that the stop part 441 of the driven component 44 moves away from the opening of the mounting hole 413. The unlocking notch 442 rotates to the opening of the mounting hole 413. When the unlocking notch 442 rotates to the opening of the mounting hole 413, the handle assembly 2 is unlocked. When the handle assembly 2 is rotated, the locking end 511 slides into contact with the fixed component 1. The locking component 51 is squeezed by the fixed component 1 and moves in the mounting hole 413. The abutting end 512 can extend out of the mounting hole 413, so that the handle assembly 2 can rotate circumferentially relative to the fixed component 1, thereby unlocking the handle assembly 2.

[0064] When locking the low-voltage drawer cabinet handle lock, the operator issues a locking command through an external terminal device. The control board receives the locking command and controls the motor to work. The motor reverses and drives the driving member 43 to rotate. The rotation of the driving member 43 drives the driven member 44 to rotate, causing the stop part 441 of the driven member 44 to rotate to the opening of the mounting hole 413. When the stop part 441 rotates to the opening of the mounting hole 413, the locking of the handle assembly 2 is completed. The locking end 511 falls into the locking groove 1211 and, under the action of the elastic member 52, maintains elastic contact with the bottom of the locking groove 1211. The stop part 441 rotates to the opening of the mounting hole 413, restricting the movement of the locking member 51, so that the handle assembly 2 cannot rotate, thereby achieving the locking of the handle assembly 2.

[0065] Among them, the locking element 51 can be a locking pin or other locking structure, and the elastic element 52 can be a spring or a spring sheet.

[0066] Continue to refer to Figures 1 to 6 The electric lock cylinder 42 also includes a mechanical unlocking lock cylinder, which allows an external mechanical key to be inserted. When an external mechanical unlocking lock cylinder is inserted, the mechanical unlocking lock cylinder can drive the driving member 43 to rotate, so as to drive the locking assembly 5 to unlock or lock through the driven member 44.

[0067] This design allows for the locking and unlocking of handle assembly 2 in emergency situations, thereby improving the performance of the low-pressure drawer cabinet handle lock.

[0068] The handle assembly 2 includes a handle 21 and a cover 22. The handle 21 has a mounting cavity 2121, an electric lock cylinder 42 is located in the mounting cavity 2121, and the lock cylinder hole of the mechanical unlocking lock cylinder is exposed at the opening of the mounting cavity 2121. The cover 22 is rotatably connected to the handle 21 and is used to close or open the opening of the mounting cavity 2121.

[0069] The cover 22 effectively prevents dust from entering the mechanical unlocking lock cylinder, thus improving the cleanliness of the mechanical unlocking lock cylinder and enhancing its smooth locking and unlocking performance.

[0070] Continue to refer to Figures 1 to 6 The electric lock structure 3 also includes a first position detection element 7, a second position detection element 8, and a magnetic induction element 9. The magnetic induction element 9 is disposed on the mounting component 41. The first position detection element 7 and the second position detection element 8 are both disposed on the fixing component 1 and are spaced apart along the circumferential direction. The first position detection element 7 and the magnetic induction element 9 are magnetically coupled to detect whether the handle assembly 2 is in the locked state; the second position detection element 8 and the magnetic induction element 9 are magnetically coupled to detect whether the handle assembly 2 is in the unlocked state.

[0071] This configuration allows for real-time detection of the unlocked and locked states of the handle assembly 2, enabling better monitoring of the handle assembly 2 and thus improving the performance of the low-pressure drawer cabinet handle lock.

[0072] Among them, the first position detection element 7 and the second position detection element 8 can both be magnetic steel elements, and the magnetic induction element 9 can be a Hall sensor, which works in conjunction with the magnetic induction of the magnet; the magnetic induction element 9 can also be other sensors with magnetic induction, as long as they can detect the position of the magnet, which will not be listed here.

[0073] Continue to refer to Figures 1 to 6 The fixing component 1 includes a fixing base 11 and a locking plate 12. The fixing base 11 is fixedly installed on the drawer door, and the locking plate 12 is fixedly connected to the fixing base 11. The locking plate 12 has multiple arc-shaped locking areas 121 on the side opposite to the fixing base 11. The multiple arc-shaped locking areas 121 are distributed at intervals along the circumferential direction of the locking plate 12. Each arc-shaped locking area 121 has at least one locking groove 1211. In the locked state, the locking groove 1211 locks and engages with the locking component 5.

[0074] In the locked state, the locking end 511 extends into the locking groove 1211, and the stop part 441 restricts the abutting end 512 from extending out of the mounting hole 413, so that the locking end 511 cannot be withdrawn from the locking groove 1211, thereby locking the handle assembly 2.

[0075] In this embodiment, each arc-shaped locking region 121 has two locking grooves 1211, which are spaced apart. In the locked state, the locking end 511 can slide freely between the two locking grooves 1211, meaning that the handle assembly 2 can rotate slightly in the locked state. A limiting region 122 is formed between each arc-shaped locking region 121. In the locked state, the locking end 511 can only slide between the two locking grooves 1211 and cannot slide past the limiting region 122, thereby locking the handle assembly 2.

[0076] With this configuration, two locking slots 1211 are formed within the arc-shaped locking area 121. When the circuit breaker in the drawer cabinet trips, the two locking slots 1211 provide a small range of rotation space for the handle assembly 2. The handle assembly 2 rotates at a small angle to drive the electrical lock structure 3 to control the closing of the circuit breaker. This avoids the circuit breaker from becoming stuck and unable to move after tripping.

[0077] The edge of the fixed base 11 is marked with an unlocked position indicator (ON), a locked position indicator (OFF), and a tripped position indicator (TRIP). The outer peripheral wall of the mounting body 212 is marked with position arrows. When locked, the position arrows point to the locked position indicator; when unlocked, the position arrows point to the unlocked position indicator; when the position arrows point to the tripped position indicator, the circuit breaker of the drawer cabinet is in the tripped state.

[0078] This setup provides clear instructions, making it easy for users to observe and use, thereby improving the user experience.

[0079] Continue to refer to Figures 1 to 6 The handle assembly 2 also includes a limiting member 24, which is fixedly connected to the electric lock structure 3 and rotatably mounted on the fixed base 11. The limiting member 24 has a limiting part 241, and the fixed base 11 has two limiting parts 113 spaced apart in the circumferential direction. The limiting part 241 rotates between the two limiting parts 113 and cooperates with any one of the two limiting parts 113. The limiting member 24 limits the rotation angle of the handle assembly 2 through the limiting part 241. The limiting member 24 is fixedly connected to the mounting member 41 by a screw, and the limiting member 24 rotates synchronously during the rotation of the electric lock structure 3.

[0080] The fixed base 11 is provided with a first receiving groove 111 and a second receiving groove 112 in sequence along the direction toward the locking piece 12. The first receiving groove 111 and the second receiving groove 112 are connected and arranged in a manner, and the radial dimension of the second receiving groove 112 is greater than the radial dimension of the first receiving groove 111. The limiting member 24 is rotatably disposed in the first receiving groove 111, the limiting part 113 is formed in the groove wall of the first receiving groove 111, and the locking piece 12 is fixedly disposed in the second receiving groove 112.

[0081] The limiting member 24 can be a limiting piece or a limiting plate, and the limiting part 241 is formed on the outer peripheral wall of the limiting member 24.

[0082] The low-voltage drawer cabinet handle lock also includes a connector 25. The middle of the fixed base 11, the locking plate 12 and the limiting member 24 are all hollow. One end of the connector 25 passes through the fixed base 11, the locking plate 12 and the limiting member 24 and is connected to the electric lock structure 3. The connector 25 rotates synchronously with the electric lock structure 3. The connector 25 is used to turn the circuit breaker closed or opened by the toggle member.

[0083] The connector 25 can be a connecting rod with a cross-section in the form of a square, rectangle, triangle, pentagon, hexagon, etc. The mounting part 41 is provided with a socket for inserting the connecting rod. The shape of the socket is adapted to the shape of the connecting rod to limit the connector 25, thereby synchronously driving the connector 25 to rotate.

[0084] The above description is only an optional embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
