Description

Technical Field

[0001] This invention relates to the field of door locks, and more particularly to a mechanism for preventing accidental locking of substation equipment cabinet doors. Background Technology

[0002] An anti-misoperation interlocking device is a mechanical device installed on high-voltage electrical equipment to prevent accidental opening or closing of circuit breakers. It utilizes its own predetermined interlocking function to prevent misoperation.

[0003] A search revealed Chinese patent application CN117418747A, which discloses an anti-misoperation locking device for power cabinet doors, relating to the technical field of anti-misoperation locking equipment. This anti-misoperation locking device includes a power cabinet, a door, and a key, as well as an anti-misoperation locking device, a lubrication device, and a waterproofing device. The anti-misoperation locking device includes a lock cylinder, a C-shaped block, a pressure block, an L-shaped rod, a rotating wheel, a lever, a bell, an arc-shaped block, a second L-shaped rod, a limiting block, a lock groove, a bolt, and a disc. A limiting hole is formed on the door surface, and a slot is formed inside the door. The lock cylinder passes through the limiting hole and is rotatably mounted inside the slot. The C-shaped block is fitted onto the surface of the lock cylinder, and the pressure block is slidably mounted on the surface of the C-shaped block. Forcibly pulling out the bolt and resetting the arc-shaped block will trigger an alarm, reminding staff to reset the lock cylinder, thus achieving an anti-theft effect and improving the security of the power cabinet.

[0004] In existing cabinet doors, the bolt engages with the lock groove after the door is locked, thus achieving the locking effect. However, during the locking process, the bolt is usually able to spring back, resulting in a low locking security level for the cabinet door. Summary of the Invention

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A substation equipment cabinet door anti-misoperation locking mechanism includes a housing and a connecting cover. The connecting cover is disposed on the housing. The adjacent sides of the housing are respectively provided with a lock tongue opening, a pin hole and a slot, and the lock tongue opening is located below the pin hole on the same side. The feature is that: the slot is provided with a locking component and an anti-misoperation locking component, and the anti-misoperation locking component and the locking component are linked and cooperate with each other. When the key is inserted into the lock cylinder and turned, the locking component works to match the side opening.

[0006] Preferably, the locking assembly includes a lock body, a lock cylinder, a connecting body, a transmission seat, a bolt connecting plate, a bolt, a pin connecting seat, a pin, and a transmission component; When the cabinet door needs to be locked, insert a special key into the lock cylinder and turn it. The lock cylinder drives the transmission component to rotate and drives the transmission seat to move to one side. The transmission seat pushes the bolt, causing it to extend from the bolt opening and insert into the lock groove on the cabinet door frame. At the same time, the transmission component causes the bolt to extend from the bolt hole and insert into the slot above the cabinet door frame.

[0007] Preferably, the anti-misoperation locking assembly includes a gear, a third rack, a rotating component, a locking plate, and two limiting components. The third rack is provided with a movable plate, and the movable plate is provided with a support column.

[0008] Preferably, the rotating component includes a support plate and a turntable, and the turntable is rotatably connected to the support plate along the axial direction.

[0009] Preferably, the support plate is fixedly connected to one side of the slot, the outer periphery of the turntable is provided with a spiral groove, the support column extends into and slides into the spiral groove, and the movement of the moving plate is converted into the rotational motion of the turntable through the support column.

[0010] Preferably, the limiting component includes a limiting frame, a limiting cylinder, a limiting spring plate, a push plate, and a buffer pad.

[0011] Preferably, the top of the limiting frame is fixedly connected to the slot, the buffer pad is disposed between one side of the limiting frame and the push plate, one side of the limiting cylinder is fixedly connected to the limiting frame, a piston plate is slidably connected to its inner wall, a spring is disposed between the top of the piston plate and the inner top wall of the limiting cylinder, the bottom of the piston plate is fixedly connected to the limiting spring plate, and the buffer pad and the limiting cylinder are connected through a conduit.

[0012] Preferably, when locked, the locking plate is limited by the limiting member, which allows the locking tongue and the bolt to be inserted into the lock groove and the slot.

[0013] The beneficial effects of this invention are as follows: 1. This invention, through its locking assembly, allows for effective locking of the cabinet door. When a key is inserted into the keyhole, the key rotates the lock cylinder, which in turn rotates the transmission component. This transmission component then moves the transmission seat and the latch connecting plate, causing the latch to insert into the lock groove, thus locking the cabinet door. Simultaneously, the transmission component rotates the rotating rod, causing the bolt connecting seat to insert the bolt into the slot above the lock groove. The combined action of the latch and the bolt effectively locks the cabinet door, improving its security and preventing a decrease in safety due to relying solely on the latch. 2. This invention, through its anti-misoperation locking component, ensures that when the cabinet door needs to be opened, the key is reversed. The key drives the lock cylinder to reverse, causing the bolt to retract from the lock groove into the housing through the meshing of the drive wheel and the first rack. Simultaneously, the bolt retracts into the housing under the action of the drive wheel, driven wheel, and second rack. During this process, the gear rotates synchronously with the rotating rod. The gear's rotation meshes with the third rack, which in turn moves the support column. This movement of the support column, along with the spiral groove, causes the turntable to rotate. At this time, the locking plate rotates with the turntable. When the locking plate rotates into the interior of the limiting component, as the locking plate continues to move, it pushes the push plate to move. As the push plate moves, it compresses the buffer pad. At this time, the gas inside the buffer pad is transported to the interior of the limiting cylinder through the conduit under the action of air pressure. The air pressure inside the limiting cylinder increases, and the piston plate pushes the limiting spring plate downward under the action of air pressure, thereby limiting the locking plate to keep the latch and bolt inside the housing. This prevents the latch from popping out after the cabinet door is unlocked, thus preventing the cabinet door from being accidentally locked. Similarly, when locking, limiting the locking plate ensures that the latch and bolt are inserted into the lock groove and slot, thereby improving the locking effect of the cabinet door.

Detailed Implementation

[0016] Example 1, referring to Figures 1-5 The anti-misoperation locking mechanism for substation equipment cabinet doors includes a housing 1. A connecting cover 2 is fixedly connected to one side of the housing 1 by bolts to facilitate the installation and maintenance of the internal mechanism. A slot 8 is opened on one side of the housing 1, and a locking component is provided on one side inside the slot 8.

[0017] The locking assembly includes a lock body 9, a lock cylinder 3, a connecting body 10, a transmission seat 19, a lock tongue connecting plate 16, a lock tongue 5, a pin connecting seat 15, a pin 7, and a transmission component 12. The two ends of the lock body 9 are respectively connected to the slot 8 and the connecting cover 2 by bolts to achieve reliable fixation.

[0018] The bottom of the lock body 9 is welded to the connecting body 10. The lock cylinder 3 is rotatably connected inside the lock body 9. A lock hole is provided on one side of the lock cylinder 3. The lock hole can be cross-shaped, straight, or irregularly shaped to accommodate different key configuration requirements.

[0019] A transmission groove is provided between the lock body 9 and the connecting body 10. The transmission seat 19 is slidably connected to the bottom of the transmission groove. One end of the transmission seat 19 is connected to one side of the lock tongue connecting plate 16 by bolts. The lock tongue 5 is fixed to one side of the lock tongue connecting plate 16. A lock tongue opening 4 is provided through one side of the housing 1, and the lock tongue opening 4 is slidably connected to the lock tongue 5. The end of the lock tongue 5 is designed as a bevel or arc surface structure to facilitate smooth insertion into the lock groove during the locking process. A lock tongue opening 4 is provided on the housing 1, and the lock tongue 5 can extend or retract into the housing 1 through the lock tongue opening 4.

[0020] Specifically, when the end of the latch 5 is designed as a beveled structure, the beveled design (such as the arc-shaped bevel of a wedge-shaped latch) can reduce the friction between the latch and the keyhole, improve the efficiency of opening and closing the door, and is especially suitable for high-frequency use scenarios. In addition, the beveled structure can compensate for the gap between the cabinet door frame, reduce the noise of closing the door, and at the same time reduce lateral movement through the movable piece to ensure the stability of opening and closing the door.

[0021] Specifically, when the end of the latch 5 is designed with a rounded surface structure, it can reduce the impact of the latch on the root, reduce noise and extend service life; at the same time, the rounded transition design can reduce sharp-angle collisions and reduce the risk of accidental damage.

[0022] Based on the above, a pin hole 6 is provided through one side of the housing 1 near the top. The pin 7 is slidably connected to the pin hole 6. One end of the pin 7 is fixedly connected to the pin connecting seat 15. The pin connecting seat 15 is connected to the transmission seat 19 through the transmission component 12.

[0023] To ensure the straightness and accuracy of the movement of the locking tongue 5, a positioning hole 18 is provided through one side of the transmission seat 19, and a positioning pin 11 is slidably connected to the inner wall of the positioning hole 18. The two ends of the positioning pin 11 are fixedly connected to the two sides of the slot 8.

[0024] Based on the above, the transmission component 12 is used to convert the rotational motion of the lock cylinder 3 into the linear motion of the transmission seat 19 and the pin connecting seat 15. Specifically, the transmission component 12 consists of a driving wheel 20, a first rack 21, a driven wheel 22, a second rack 23, and a rotating rod 17. The driving wheel 20 is fixedly sleeved on the outer wall of the lock cylinder 3. The bottom of the first rack 21 is connected to the transmission seat 19 by bolts. The first rack 21 meshes with the driving wheel 20. One side of the slot 8 is rotatably connected to the rotating rod 17 by a bearing. The driven wheel 22 is fixedly sleeved on the outer wall of the rotating rod 17. The driving wheel 20 meshes with the driven wheel 22. The top of the second rack 23 is fixed to the bottom of the pin connecting seat 15. The second rack 23 meshes with the driven wheel 22.

[0025] Based on the above, a sliding groove is provided at the top of the slot 8, the slide plate 14 is slidably connected in the sliding groove, and the bottom of the slide plate 14 is connected to the pin connector 15 by bolts.

[0026] Locking process: When the cabinet door needs to be locked, a special key is inserted into the lock cylinder 3 and turned. The lock cylinder 3 drives the drive wheel 20 to rotate. The drive wheel 20 drives the first rack 21 to move through gear meshing. The first rack 21 drives the transmission seat 19 to slide to one side along the positioning pin 11. The transmission seat 19 pushes the lock tongue 5 through the lock tongue connecting plate 16, so that it extends out from the lock tongue opening 4 and inserts into the lock groove on the cabinet door frame.

[0027] At the same time, the rotation of the driving wheel 20 drives the driven wheel 22 to rotate through meshing. The driven wheel 22 drives the rotating rod 17 to rotate synchronously. The driven wheel 22 on the rotating rod 17 drives the second rack 23 meshing with it to move to one side. The second rack 23 drives the pin connecting seat 15 and the pin 7 fixed thereon to move, so that the pin 7 extends out from the pin hole 6 and is inserted into the slot above the cabinet door frame.

[0028] The combined action of the latch 5 and the bolt 7 achieves double locking of the cabinet door, significantly improving the security and reliability of the locking mechanism.

[0029] Unlocking process: Turning the key in the opposite direction causes the lock cylinder 3 to rotate the drive wheel 20 in the opposite direction. The drive wheel 20 drives the first rack 21 to move, causing the transmission seat 19, the lock tongue connecting plate 16, and the lock tongue 5 to retract into the housing 1 and disengage from the lock groove. At the same time, the drive wheel 20 drives the pin connecting seat 15 and the pin 7 to move in the opposite direction through the driven wheel 22 and the second rack 23, causing the pin 7 to retract into the pin hole 6 and disengage from the slot, so that the cabinet door can be opened.

[0030] Example 2, refer to Figures 1-7 Compared with Embodiment 1, the anti-misoperation locking mechanism for substation equipment cabinet doors is based on Embodiment 1, with an anti-misoperation locking component 13 provided on one side of the slot 8, and the anti-misoperation locking component 13 and the locking component cooperate to prevent the cabinet door from locking or unlocking unexpectedly, and to improve the holding force of the locking state.

[0031] Based on the above, the anti-misoperation locking assembly 13 includes a gear 24, a third rack 25, a rotating component, a locking plate 29, a support column, and two limiting components 30. The gear 24 is fixedly sleeved on the outer circumference of the rotating rod 17 and meshes with the third rack 25. The third rack 25 is slidably connected to one side of the slot 8, and a movable plate is fixedly connected to one end of it. The rotating component is set on one side of the slot 8, and its top is fixedly connected to the locking plate 29. The two limiting components 30 are respectively fixed on both sides of the slot 8 and symmetrically distributed on both sides of the rotating component.

[0032] Based on the above, the rotating component includes a support plate 26 and a turntable 27 that are rotatably connected to each other. The support plate 26 is bolted to one side of the slot 8. The turntable 27 has a spiral groove 28 on its outer periphery. One end of the support column is fixed to the movable plate, and the other end extends into and slides into the spiral groove 28. The movement of the movable plate is converted into the rotational motion of the turntable 27 through the support column. When the support column moves, it will drive the turntable 27 to rotate along the direction of the spiral groove 28. The gear 24 will rotate synchronously with the rotation of the rotating rod 17. When the gear 24 rotates, it will drive the third rack 25 to move through meshing. When the third rack 25 moves, it will drive the support column to move synchronously. When the support column moves, it will drive the turntable 27 to rotate along the direction of the spiral groove 28. At this time, the clamping plate 29 will rotate with the rotation of the turntable 27.

[0033] Based on the above, the limiting component 30 includes a limiting frame 31, a limiting cylinder 32, a limiting spring plate 33, a push plate 34, and a buffer pad 35. The top of the limiting frame 31 is bolted to the slot 8. The buffer pad 35 is disposed between one side of the limiting frame 31 and the push plate 34. One side of the limiting cylinder 32 is bolted to the limiting frame 31, and a piston plate is slidably connected to its inner wall. A spring is disposed between the top of the piston plate and the inner top wall of the limiting cylinder 32. The bottom of the piston plate is bolted to the limiting spring plate 33. The buffer pad 35 is made of hollow elastic material, and the buffer pad 35 is connected to the limiting cylinder 32 through a conduit 36. The clamping plate 29 rotates with the rotation of the turntable 27. When the clamping plate 29 rotates into the interior of the limiting component 30, As the locking plate 29 continues to move, it pushes the push plate 34 to move. When the push plate 34 moves, it compresses the buffer pad 35. At this time, the gas inside the buffer pad 35 is transported to the inside of the limiting cylinder 32 through the conduit 36 ​​under the action of air pressure. The air pressure inside the limiting cylinder 32 will increase, and the piston plate will push the limiting spring plate 33 to move down under the action of air pressure, thereby limiting the locking plate 29. This will limit the locking tongue 5 and the bolt 7 inside the housing 1, preventing the locking tongue 5 from popping out after the cabinet door is unlocked, thus preventing the cabinet door from being accidentally locked. Similarly, when locking, by limiting the locking plate 29, the locking tongue 5 and the bolt 7 can be inserted into the lock groove and slot, thereby improving the locking effect of the cabinet door.

[0034] Mistake prevention and reinforcement during the interlocking process: When the key is turned to lock, the lever 17 drives the gear 24 to rotate, the gear 24 drives the third rack 25 to move, and the third rack 25 drives the support column to move synchronously through the moving plate. During the movement, the end of the support column moves along the spiral groove 28 on the turntable 27, thereby forcing the turntable 27 to rotate around its axis. The turntable 27 drives the top locking plate 29 to rotate, and the locking plate 29 then rotates into the limiting space of one of the limiting members 30.

[0035] As the locking plate 29 continues to screw in, its end contacts and pushes the push plate 34 inside the limiting member 30. The push plate 34 compresses the buffer pad 35. After the buffer pad 35 is compressed, the gas inside it is forced into the limiting cylinder 32 through the conduit 36, causing the air pressure inside the limiting cylinder 32 to increase. The air pressure pushes the piston plate to move downward against the spring force. The piston plate drives the limiting spring plate 33 to move downward, so that the limiting spring plate 33 jams or presses tightly against the locking plate 29, thereby locking the locking plate 29 in this position.

[0036] This locking state indirectly makes it difficult for the rotating rod 17 to reverse through the rotating component and transmission chain, thereby enhancing the holding force of the locking tongue 5 and the bolt 7 in the locked position (extended state), preventing accidental unlocking due to vibration or abnormal operation, and improving the reliability of locking. At the same time, this process is linked to the locking action and requires no additional operation.

[0037] Preventing accidental unlocking and unlocking during the unlocking process: When unlocking is required, the key is turned in the reverse direction, the lever 17 rotates in the reverse direction, driving the gear 24 to reverse, the gear 24 drives the third rack 25 to move in the reverse direction, the third rack 25 drives the turntable 27 to rotate in the reverse direction through the support, the locking plate 29 will squeeze the limiting spring plate 33, the limiting spring plate 33 will bend under pressure, during the bending process, the locking plate 29 pushes the limiting spring plate 33 upward, when the top of the locking plate 29 and the bottom of the limiting spring plate 33 are on the same plane, the locking plate 29 then rotates out of the limiting member 30.

[0038] During the process of the locking plate 29 being rotated out, the pressure on the push plate 34 is released, and the buffer pad 35 returns to its original shape due to its elasticity, generating negative pressure inside. The gas in the limiting cylinder 32 is drawn back through the conduit 36, the air pressure in the limiting cylinder 32 decreases, and the piston plate is reset under the action of the top spring, which drives the limiting spring plate 33 to rise and release the locking of the locking plate 29.

[0039] The rotating rod 17 can be reversed smoothly, which in turn drives the bolt 5 and the pin 7 to retract through the transmission component 12, thus completing the unlocking. This mechanism ensures that the locked state can only be released when the key is operated normally, effectively preventing accidental unlocking caused by misoperation. At the same time, after unlocking, the anti-mislocking component 13 restricts the latch 29 to the position away from the limit component 30, which can indirectly help the bolt 5 and the pin 7 to remain stably in the retracted position, preventing them from accidentally popping out due to gravity or vibration and causing the cabinet door to lock accidentally.

[0040] In summary, with the help of the above-mentioned technical solution of the present invention: when locking the cabinet door, the key is inserted into the keyhole, and the key drives the lock cylinder 3 to rotate. Simultaneously, the lock cylinder 3 drives the drive wheel 20 to rotate. When the drive wheel 20 rotates, it meshes with the first rack 21. When the first rack 21 meshes, it drives the transmission seat 19 and the latch connecting plate 16 to move, thereby inserting the latch 5 into the lock groove, thus completing the locking of the cabinet door. During this process, the drive wheel 20, through meshing, causes the driven wheel 22 to drive the rotating rod 17 to rotate synchronously. And when the driven wheel 22 rotates, it... The engagement of the second rack 23 with the first rack 21 causes the bolt 7 to be inserted into the slot above the lock groove. This, combined with the action of the bolt 5 and the bolt 7, effectively locks the cabinet door, improving its security and preventing a decrease in safety due to relying solely on the bolt 5. When the door needs to be opened, the key is reversed, causing the lock cylinder 3 to rotate in reverse. The engagement between the drive wheel 20 and the first rack 21 causes the bolt 5 to retract from the lock groove into the housing 1. Simultaneously, the bolt is engaged with the drive wheel 20... Driven by the driven wheel 22 and the second rack 23, the gear 24 is retracted into the housing 1. During this process, the gear 24 rotates synchronously with the rotating rod 17. When the gear 24 rotates, it meshes with the third rack 25, which in turn moves the support column. As the support column moves, it rotates the turntable 27 along the direction of the spiral groove 28. At this time, the clamping plate 29 rotates with the turntable 27. When the clamping plate 29 rotates into the limit member 30, it pushes the push plate 34 to move as it continues to move. When the device is activated, the buffer pad 35 is compressed. At this time, the gas inside the buffer pad 35 is transported to the inside of the limiting cylinder 32 through the conduit 36 ​​under the action of air pressure. The air pressure inside the limiting cylinder 32 will increase, and the piston plate will push the limiting spring plate 33 to move downward under the action of air pressure, thereby limiting the locking plate 29. This will limit the locking tongue 5 and the bolt 7 inside the housing 1, preventing the locking tongue 5 from popping out after the cabinet door is unlocked, thus preventing the cabinet door from being accidentally locked. Similarly, when locking, by limiting the locking plate 29, the locking tongue 5 and the bolt 7 can be inserted into the lock groove and slot, thereby improving the locking effect of the cabinet door.

[0041] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
