Description

Technical Field

[0001] This application relates to the field of low-voltage electrical technology, specifically to an operating box. Background Technology

[0002] In power systems, switchgear is the core equipment for realizing functions such as circuit on / off control, fault protection, and system maintenance. As the human-machine interface and safety control component of switchgear, the control box undertakes key functions such as switching operating modes, locking safety padlocks, and indicating position status. Its structural rationality and safety protection performance directly determine the safety and operational stability of switchgear.

[0003] In existing technologies, the control box generally meets the following control logic: in automatic mode, manual operation is prohibited to ensure the independence and safety of remote automatic control; in manual mode, the remote automatic control signal is shielded to avoid interference between the automatic control signal and manual operation; after manual tripping is completed, both manual and automatic operation are disabled by locking the padlock, so as to meet the safety requirements for equipment power outage inspection, maintenance and repair.

[0004] However, existing control boxes are often complex in structure, have complicated assembly processes, and have high production costs. Summary of the Invention

[0005] This application provides an operation box that simplifies the structure of the operation box, reduces assembly difficulty, and saves on the cost of the operation box.

[0006] To achieve the above objectives, this application provides an operating box, including a base, a rotating shaft, a knob, and a padlock. The base has a mounting groove. The rotating shaft is rotatably mounted on the base and is used for linkage connection with the switch of the operated component.

[0007] The knob is rotatably mounted on the base. The knob includes a knob body and a pressing part. The pressing part extends into a mounting groove. The knob body has a first shielding hole, a through hole, and a second shielding hole. The knob has automatic, manual, and padlock positions relative to the base. When the knob is in the automatic, manual, and padlock positions, the first shielding hole, the through hole, and the second shielding hole correspond to the operating end of the rotating shaft, respectively. When the knob switches between the automatic and manual positions, it drives the signal element of the operating box to switch between a closed and open state.

[0008] The padlock assembly includes a padlock portion and a limiting portion connected together. The limiting portion is slidably disposed within the mounting groove along its depth direction. The padlock assembly has a limiting position and a releasing position relative to the base. When the knob is in the automatic or manual position, the padlock assembly is in the limiting position, with the pressing portion in limiting contact with the limiting portion, and the padlock portion fitting snugly against the base. When the knob is in the padlock position, the pressing portion disengages from the limiting portion, and the padlock portion can move away from the base.

[0009] When the above technical solution is adopted, with the knob in the automatic position, the first shielding hole rotates to the operating end position. At this time, the operating end is blocked by the first shielding hole, and the operator cannot manually operate the shaft. At this point, the operated component can be remotely controlled to switch between the open and closed states.

[0010] In other words, when the knob is in the automatic position, the operator cannot manually rotate the shaft. This ensures that the operated component is protected from manual operation in automatic mode, guaranteeing the independence and safety of remote automatic control.

[0011] When the knob is in the manual position, the through hole corresponds to the operating end of the rotating shaft. At this time, the operating end is exposed, allowing the operator to directly access it through the through hole and operate the rotating shaft. Simultaneously, the signal element can block remote automatic control signals when the knob is in the manual position. In this state, it is impossible to switch the operated component between open and closed states via remote operation.

[0012] In other words, when the knob is in the manual position, the operated component will not respond even if it receives a remote automatic control signal. The operator can only manually operate the shaft to switch the operated component between the open and closed states.

[0013] When the knob is in the manual position, the shaft can be rotated to put the operated component in the open state. Then, rotating the knob switches it from the manual position to the padlock position. At this time, the second shielding hole corresponds to the operating end of the shaft. The operating end is blocked by the second shielding hole, preventing the operator from accessing the operating end and thus preventing manual operation of the shaft.

[0014] Next, switch the padlock from the limit position to the release position. The padlock moves away from the base, creating a gap between the padlock and the base. The operator can then hang the protective lock on the padlock. In this situation, safe operations such as power outage inspections and maintenance can be performed on the equipment, preventing unsuspecting operators from operating the control box.

[0015] The operation box provided in this application embodiment has a knob and a padlock on the base. The knob is connected to a signal element, enabling the control logic of the operation box. Specifically, when the knob is in the automatic position, the operator cannot manually operate the shaft due to the first shielding hole, ensuring the independence and security of remote automatic control. When the knob is in the manual position, the operator can directly operate the shaft, and the signal element can shield the remote automatic control signal when the knob is in the manual position. When the knob is in the padlock position, the operator cannot manually operate the shaft due to the second shielding hole, and the remote automatic control signal is also shielded, meaning both manual and automatic operation are ineffective.

[0016] The control box has fewer parts and a simpler structure, making it easier to install and operate. This shortens the production and installation cycle, reducing production costs. It also allows for a smaller overall size.

[0017] In one possible implementation, the signal element can be one of a position switch, limit switch, micro switch, magnetic switch, or relay.

[0018] By using position switches, limit switches, signal elements, magnetic switches, or relays as signal elements, the mechanical rotation of the shaft can be converted into the opening and closing control of the signal elements. This allows for a wider variety of signal elements to be selected and configured according to actual conditions.

[0019] In one possible implementation, the control box further includes a panel that covers the base. The panel has through holes, display holes, and actuation holes.

[0020] The through hole corresponds to the padlock part, which protrudes from the panel away from the base when the padlock is in the released position.

[0021] The display hole corresponds to the operating end. The actuation hole corresponds to the rotating part of the knob.

[0022] When using the above technical solution, the through hole allows the operator to hang the protective lock on the padlock part. The display hole allows the operator to observe the specific position of the knob through the panel. The actuation hole allows the operator to directly access the rotating part to rotate the knob.

[0023] The panel design protects the knobs, improves the sealing of the control box, and effectively prevents external dust, iron filings, oil, moisture, etc. from entering the control box, ensuring that the control box can operate normally in harsh environments such as outdoors or chemical plants, thus expanding the scope of application of the control box.

[0024] At the same time, it can reduce the risk of operators or tools accidentally touching the exposed electrical contacts inside the control box, prevent equipment malfunction or electric shock caused by accidental contact, and improve electrical safety performance.

[0025] In one possible implementation, the orthographic projection of the padlock portion onto the limiting portion lies within the limiting portion along the depth direction of the mounting groove. The dimension of the through hole in a first direction is smaller than the dimension of the limiting portion. The first direction is perpendicular to the depth direction of the mounting groove.

[0026] When the above technical solution is adopted, when the padlock is in the released position, the limiting part can slide along the depth direction of the mounting groove, thereby synchronously driving the padlock part to move away from the base. When the limiting part is located at the opening of the mounting groove, the position of the limiting part is limited by the knob body and the cover. In this way, the limiting part is prevented from sliding out of the mounting groove, enhancing the structural strength of the operating box.

[0027] In one possible implementation, the rotating shaft has an open position and an closed position relative to the base. The operating terminal is equipped with indicator markings that correspond to the display aperture. The panel displays open and closed indicators.

[0028] When the shaft is in the open position, the indicator corresponds to the open indicator. When the shaft is in the closed position, the indicator corresponds to the closed indicator.

[0029] When the above technical solution is adopted, the indicator rotates synchronously with the rotating shaft, forming a fixed angular correspondence with the indicator on the panel, and there will be no phenomenon of indicator misalignment or indicator failure.

[0030] When the shaft is in the open position, the indicator is facing the open indicator, and the operated component is in the open state. When the shaft is in the closed position, the indicator is facing the closed indicator, and the operated component is in the closed state.

[0031] In this way, operators can more intuitively determine whether the operated device is in the open or closed state, reducing the possibility of observation errors, perspective errors, and comprehension errors.

[0032] At the same time, it does not rely on power supply, indicator lights, or electrical signals, and can still indicate normally in the event of a fault, thus having a high level of safety.

[0033] In one possible implementation, a blocking part is provided on the side of the limiting part near the rotating shaft.

[0034] The rotating shaft is provided with a connected sliding groove and a rotating groove. The rotating groove is arranged along the circumference of the rotating shaft, and the sliding groove is arranged along the axial direction of the rotating shaft.

[0035] When the padlock is in the limit position, the blocking part extends into the rotating groove, and the rotating shaft can switch between the open and closed positions.

[0036] When the padlock is in the released position, the rotating shaft is in the open position, and the blocking part extends into the sliding groove to prevent the rotating shaft from switching from the open position to the closed position.

[0037] When the above technical solution is adopted, when the padlock is in the limit position, the blocking part extends into the rotating groove. The rotating groove provides clearance space for the circumferential rotation of the rotating shaft, so that the rotating shaft can freely rotate and switch between the open and closed positions without affecting the normal opening and closing operation of the operated component.

[0038] When the padlock is in the released position, this is only permitted when the pivot is in the open position.

[0039] At this point, the blocking part extends into the sliding groove, which is positioned along the axis of the rotating shaft. The axis of the rotating shaft extends parallel to the depth direction of the mounting groove.

[0040] The padlock can slide relative to the base. At the same time, the blocking part forms a circumferential rotation limit on the rotating shaft, preventing the rotating shaft from switching from the open position to the closed position. This achieves mechanical locking of the operated component in the open state, ensuring that the operated component cannot be accidentally closed after padlocking, improving operational safety and reliability, and avoiding the safety risk of accidental closing after padlocking.

[0041] In one possible implementation, a protrusion is provided on the knob body.

[0042] The base has three limiting grooves that mate with the protrusion. When the knob is in the automatic, manual, or padlock position, it corresponds to one of the three limiting grooves.

[0043] When the knob is in the automatic, manual, or padlock position, the protruding part engages with the corresponding limit groove.

[0044] When the above technical solution is adopted, three limiting grooves are provided on the base, which correspond to the automatic position, manual position and padlock position of the knob respectively. The protrusion on the knob forms a positioning with the limiting groove, so that the knob can achieve precise angle, no movement and no deviation in the three working positions, and avoid mode confusion caused by loose knob or self-rotation.

[0045] Without any external force deliberately rotating the knob, the engaging force between the protrusion and the limiting groove can resist external interference such as vibration and collision, preventing the knob from automatically switching positions during equipment operation, thereby reducing safety accidents caused by accidental knob position switching.

[0046] In one possible implementation, the base has two support portions. When the knob is in the automatic position, one of the support portions makes support contact with the knob body.

[0047] When the knob is in the padlock position, another support part is in contact with the knob body.

[0048] When the above technical solution is adopted, the two support parts respectively form mechanical stops for the automatic position and padlock position of the knob, limiting the maximum rotation range of the knob and reducing the possibility of the knob rotating too far, resulting in angular deviation, indication confusion, and other phenomena.

[0049] When the knob is in the automatic and padlock positions, the support provides support to the knob body. This ensures that the operating end can be reliably blocked when the knob is in the automatic and padlock positions.

[0050] In one possible implementation, a first sealing groove is provided on the rotating shaft along the circumference, and a first sealing ring is fitted inside the first sealing groove, with the outer surface of the first sealing ring tightly fitted to the base.

[0051] When the above technical solution is adopted, dust, water vapor, oil stains, corrosive gases and other substances can be prevented from entering the operation box through the gap between the rotating shaft and the base, which significantly improves the dustproof, waterproof and corrosion-proof capabilities of the operation box and the operated parts, and extends the service life of the operation box.

[0052] The first sealing ring is fitted into the first sealing groove, which provides a stable installation position for the first sealing ring to prevent it from shifting, misaligning, or even falling off. This ensures that the shaft and base maintain a uniform and tight seal during shaft rotation, achieving both flexibility and reliable sealing, and providing long-lasting sealing under dynamic operating conditions.

[0053] In one possible implementation, a second sealing groove is circumferentially formed on the rotation axis of the knob. A second sealing ring is fitted inside the second sealing groove, and the outer surface of the second sealing ring is in close contact with the base.

[0054] When the above technical solution is adopted, dust, water vapor, oil stains, corrosive gases and other substances can be prevented from entering the operation box through the gap between the rotating shaft and the base, which can significantly improve the dustproof, waterproof and corrosion-proof capabilities of the operation box and the operated parts, and extend the service life of the operation box.

[0055] The second sealing ring is fitted inside the second sealing groove, which provides a stable installation position for the second sealing ring to prevent it from shifting, misaligning, or even falling off. This ensures that the rotating shaft and base maintain a uniform and tight seal during knob rotation, achieving both flexibility in shaft rotation and reliable sealing, thus providing long-lasting sealing under dynamic operating conditions.

[0056] In one possible implementation, the control box also includes a baffle located on the side of the base away from the knob body.

[0057] When adopting the above technical solution, the baffle can protect the signal components, improve the sealing of the control box, and effectively prevent external dust, iron filings, oil, moisture, etc. from entering the control box, ensuring that the control box can operate normally in harsh environments such as outdoors or chemical plants, thus expanding the application range of the control box. At the same time, it can improve the sealing performance of the operated components.

[0058] In addition, it can reduce the risk of operators or tools accidentally touching signal components, prevent equipment malfunctions or electric shocks caused by accidental contact, and improve electrical safety performance. Attached Figure Description

[0074] Furthermore, the terms "first," "second," etc., in the specification and claims of this application or in the aforementioned drawings are used to distinguish different objects rather than to describe a specific order, and may explicitly or implicitly include one or more of the features.

[0075] In the description of this application, unless otherwise stated, "multiple" means two or more (including two), and similarly, "multiple groups" means two or more (including two groups).

[0076] Please combine Figures 1 to 4 As shown in the figure, this application embodiment provides an operation box, which includes a base 1, a rotating shaft 2, a knob 3, and a padlock 4.

[0077] The specific structure, dimensions, and materials of the base 1 are not specifically limited here. In a practical implementation, the base 1 can be a cuboid structure, and the base 1 can have a receiving cavity with one end open. The base 1 is connected to the housing of the operated component, with the open end of the receiving cavity facing the housing.

[0078] like Figure 5 As shown, a mounting groove 11 is provided on the base 1, and the mounting groove 11 is located on the side of the base 1 away from the receiving cavity. Simultaneously, a first mounting hole 15 and a second mounting hole 16 are also provided on the base 1. Both the first mounting hole 15 and the second mounting hole 16 are through holes.

[0079] The specific structure and dimensions of the mounting slot 11 are not specifically limited here, and shall be subject to the actual situation. The first mounting hole 15 and the second mounting hole 16 can both be cylindrical holes.

[0080] The rotating shaft 2 is rotatably mounted on the base 1 and is used for linkage connection with the switch of the operated component. The axis of the rotating shaft 2 can extend parallel to the depth direction of the mounting groove 11.

[0081] In practice, the rotating shaft 2 can have an operating end and a connecting end that are positioned opposite each other. The rotating shaft 2 can be rotatably mounted at the position of the first mounting hole 15, and the connecting end of the rotating shaft 2 can pass through the first mounting hole 15. Please refer to... Figures 3 to 5 As shown.

[0082] The connection end is linked to the switch of the operated component. When the rotating shaft 2 rotates relative to the base 1, it can synchronously drive the switch of the operated component to rotate, so that the operated component switches between the open and closed states.

[0083] In practice, the operated component can be a switching device, but it is not limited to this.

[0084] Knob 3 is rotatably mounted on base 1, and knob 3 has a rotating shaft 33, such as Figure 6 As shown. In fact, the rotating shaft 33 is rotatably connected to the base 1. The rotating shaft 33 is rotatably positioned at the second mounting hole 16.

[0085] In the embodiments provided in this application, please refer to Figure 6 and Figure 7As shown, the knob 3 also includes a knob body 31 and a pressing part 32. The rotation shaft 33 can be provided on the knob body 31.

[0086] In actual operation, the connection between the knob body 31 and the pressing part 32 can be achieved by welding, snap-fitting, or screw connection. Of course, the knob body 31 can also be integrally formed with the pressing part 32.

[0087] The connection method between the rotating shaft 33 and the knob body 31 is not specifically limited here. For example, the rotating shaft 33 and the knob body 31 can be connected by welding, snap-fitting, or screw connection. Of course, the knob body 31 can also be integrally formed with the rotating shaft 33.

[0088] When the pressing part 32 and the rotating shaft 33 are both integrally machined with the knob body 31, the knob 3 has an integral structure.

[0089] The pressing part 32 and the rotating shaft 33 are both located on the same side of the knob body 31. Furthermore, the knob body 31 is located on the side of the base 1 where the mounting groove 11 is provided.

[0090] The pressing part 32 extends into the mounting groove 11. When the knob 3 is rotated, the pressing part 32 can slide within the mounting groove 11 along the extending direction of the mounting groove 11.

[0091] It should be noted that the mounting groove 11 has an arc-shaped section, and the axis of the arc-shaped section is collinear with the rotation axis 33 of the knob 3. That is, the axis of the arc-shaped section coincides with the axis of the second mounting hole 16. The pressing part 32 extends into the arc-shaped section and is slidably disposed within the arc-shaped section along its extension direction.

[0092] Please see Figure 2 , Figure 6 and Figure 7 As shown, the knob body 31 has a first shielding hole 311, a through hole 312, and a second shielding hole 313.

[0093] In a specific implementation, through holes can be machined on the knob body 31 at positions corresponding to the first shielding hole 311 and the second shielding hole 313. Then, a shielding plate can be installed in the through hole to form the first shielding hole 311 and the second shielding hole 313. The shape of the shielding plate can be triangular, circular, or teardrop-shaped, etc., but it is not limited to these in practice.

[0094] When knob 3 rotates relative to base 1, it has three positions relative to base 1: automatic, manual, and padlock. It should be noted that when knob 3 is in the automatic position, the operated component can be switched between open and closed states via a remote automatic control signal. When knob 3 is in the manual or padlock position, the remote automatic control signal can be disabled.

[0095] In practice, when the knob 3 is in the automatic, manual, and padlock positions, the first shielding hole 311, the through hole 312, and the second shielding hole 313 correspond to the operating end of the rotating shaft 2, respectively.

[0096] It should be noted that this corresponds to the operating end of the rotating shaft 2, that is, it is located at the operating end position.

[0097] Specifically, when knob 3 is in the automatic position, the first shielding hole 311 rotates to the operating end position. At this time, the operating end is blocked by the first shielding hole 311, and the operator cannot manually operate the rotating shaft 2.

[0098] In other words, when knob 3 is in the automatic position, the operator cannot manually rotate shaft 2 due to the obstruction of the first shielding hole 311. This ensures that the operated component is prohibited from manual operation in automatic mode, thus guaranteeing the independence and safety of remote automatic control.

[0099] When knob 3 is in the manual position, the through hole 312 corresponds to the operating end of shaft 2. At this time, the operating end is exposed, and the operator can directly contact the operating end through the through hole 312 to operate shaft 2.

[0100] When knob 3 is in the padlock position, the second shielding hole 313 corresponds to the operating end of shaft 2. At this time, the operating end is blocked by the second shielding hole 313, and the operator cannot access the operating end and cannot manually operate shaft 2.

[0101] Padlock component 4 includes a padlock part 41 and a limiting part 42 connected together, such as Figure 8 As shown. The connection method between the padlock part 41 and the limiting part 42 is not specifically limited here. For example, the padlock part 41 can be indirectly connected to the limiting part 42 via a connecting rod. The extending direction of the connecting rod can be parallel to the depth direction of the mounting groove 11.

[0102] The connection method between the padlock part 41 and the connecting rod, and the connection method between the connecting rod and the limiting part 42, are not specifically limited here, and shall be subject to the actual situation.

[0103] The limiting part 42 is slidably disposed in the mounting groove 11 along the depth direction of the mounting groove 11, and the limiting part 42 matches the structure of the mounting groove 11.

[0104] When the limiting part 42 slides relative to the base 1 along the depth direction of the mounting groove 11, the padlock 4 has a limiting position and a release position relative to the base 1. When the knob 3 is in the automatic and manual positions, the padlock 4 is in the limiting position, and the pressing part 32 makes limiting contact with the limiting part 42 to prevent the padlock 4 from switching from the limiting position to the release position. At this time, the padlock part 41 is in contact with the base 1, which can prevent the operator from hanging the protective lock on the padlock part 41.

[0105] When knob 3 is in the padlock position, pressing part 32 disengages from limiting part 42. At this time, padlock part 4 is allowed to switch from the limiting position to the release position, and padlock part 41 can move away from base 1. This creates a larger gap between padlock part 41 and base 1, allowing operators to hang the protective lock on padlock part 41 for safe operation such as power outage inspection and maintenance of the equipment, preventing unsuspecting operators from operating the control box.

[0106] It should be noted that when the padlock 4 is in the released position, the limiting part 42 can slide within the mounting groove 11 along the depth direction of the mounting groove 11, thereby allowing the padlock part 41 to move away from the base 1. At this time, the extreme position of the limiting part 42 in the depth direction of the mounting groove 11 is limited by the bottom of the mounting groove 11 and the knob body 31.

[0107] Furthermore, when the knob 3 switches between the automatic and manual positions, it can drive the signal element 5 of the operation box to switch between the closed and open states.

[0108] Additionally, it should be noted that the state of the signal element 5 does not change when the knob 3 is rotated between the manual and padlock positions. For example, when the knob 3 is in the manual position and the signal element 5 is in the closed state, rotating the knob 3 to switch it from the manual to the padlock position will still keep the signal element 5 in the closed state.

[0109] In fact, the signal element 5 is disposed on the base 1, and the signal element 5 can be disposed within the receiving cavity of the base 1. The knob 3 is driven and connected to the signal element 5 to control the opening and closing of the signal element 5.

[0110] In practice, when knob 3 is in the automatic position, the operated component can be switched between the open and closed states via a remote automatic control signal. When knob 3 is in the manual or padlock position, the remote automatic control signal can be blocked.

[0111] Additionally, it is worth noting that when knob 3 is in the automatic position, signal element 5 can be either in a closed state or in a closed state.

[0112] Specifically, as one implementation, when knob 3 is in the automatic position, signal element 5 is in a closed state. In this case, when knob 3 is in the manual position and padlock position, signal element 5 is in a closed state, which can block remote automatic control signals.

[0113] As another implementation, when knob 3 is in the automatic position, signal element 5 is in the off state. In this case, when knob 3 is in the manual position and padlock position, signal element 5 is in the closed state, which can also block remote automatic control signals.

[0114] For example, when knob 3 is in the automatic position, signal element 5 is in the off state. At this time, the operated component can be switched between the open and closed states via a remote automatic control signal. When knob 3 is in the manual or padlock position, signal element 5 is in the closed state. At this time, the remote automatic control signal is blocked, and the operated component cannot be switched between the open and closed states via remote operation.

[0115] Using the operating box provided in this application embodiment, when the knob 3 is in the automatic position, the first shielding hole 311 rotates to the operating end position. At this time, the operating end is blocked by the first shielding hole 311, and the operator cannot manually operate the rotating shaft 2. At this time, the operated component can be remotely controlled to switch between the open and closed states.

[0116] When knob 3 is in the manual position, the through hole 312 corresponds to the operating end of shaft 2. At this time, the operating end is exposed, and the operator can directly contact the operating end through the through hole 312 to operate shaft 2. At the same time, the setting of signal element 5 can shield the remote automatic control signal when knob 3 is in the manual position, making it impossible to switch the operated component between the open and closed states via remote operation.

[0117] In other words, when knob 3 is in the manual position, the operated component will not respond even if it receives a remote automatic control signal. The operated component can only be switched between the open and closed states by the operator manually operating shaft 2.

[0118] When knob 3 is in the manual position, shaft 2 can be rotated to put the operated component in the open state. Then, knob 3 is rotated to switch from the manual position to the padlock position. At this time, the second shielding hole 313 corresponds to the operating end of shaft 2. The operating end is blocked by the second shielding hole 313, and the operator cannot manually operate shaft 2.

[0119] Then, the padlock 4 is switched from the limited position to the released position, and the padlock part 41 moves away from the base 1, creating a gap between the padlock part 41 and the base 1. The operator can then hang the protective lock on the padlock part 41. In this situation, safe operations such as power outage inspection, maintenance, and repair can be performed on the equipment, preventing unsuspecting operators from operating the control box.

[0120] The operation box provided in this embodiment has a knob 3 and a padlock 4 on the base 1. The knob 3 is connected to the signal element 5 of the operation box, enabling the control logic of the operation box. Specifically, when the knob 3 is in the automatic position, the operator cannot manually operate the shaft 2 due to the obstruction of the first shielding hole 311, ensuring the independence and safety of remote automatic control. When the knob 3 is in the manual position, the operator can directly operate the shaft 2, and the signal element 5 can shield the remote automatic control signal when the knob 3 is in the manual position. When the knob 3 is in the padlock position, the operator cannot manually operate the shaft 2 due to the obstruction of the second shielding hole 313, and the remote automatic control signal is also shielded, meaning both manual and automatic operation are ineffective.

[0121] The control box has fewer parts and a simpler structure, making it easier to install and operate. This shortens the production and installation cycle, reducing production costs. It also allows for a smaller overall size.

[0122] In practice, when the knob 3 rotates relative to the base 1 to switch between the automatic position, manual position and padlock position, the rotation angle of the knob 3 is not specifically limited here.

[0123] When the knob 3 switches between the automatic and manual positions, the knob 3 can rotate at an angle of 20° to 40°. For example, when the knob 3 switches between the automatic and manual positions, the knob 3 can rotate at angles of 20°, 24°, 28°, 30°, 32°, 35°, 36°, 40°, etc.

[0124] When the knob 3 is switched between the manual position and the padlock position, the knob 3 can rotate at an angle of 20° to 40°. For example, when the knob 3 is switched between the manual position and the padlock position, the knob 3 can rotate at angles of 20°, 25°, 27°, 30°, 32°, 34°, 38°, 40°, etc.

[0125] When switching between the automatic and manual positions, the rotation angle of knob 3 may be equal to or different from the rotation angle of knob 3 when switching between the manual and padlock positions.

[0126] When switching between the automatic and manual positions, knob 3 rotates by 30°. Similarly, when switching between the manual and padlock positions, knob 3 rotates by 30°. Figure 1 and Figure 2 The placement of the control box is shown as an example.

[0127] In practical implementation, a long, narrow operating handle can be provided on the rotating part 34 of the knob 3. When the knob 3 is in the manual position, the operating handle extends vertically. When the knob 3 is in the automatic position, the angle between the extension direction of the operating handle and the vertical direction is -30°. When the knob 3 is in the padlock position, the angle between the extension direction of the operating handle and the vertical direction is 30°.

[0128] In addition, when the padlock 4 is in the released position, the padlock part 41 moves away from the base 1, creating a gap between the padlock part 41 and the base 1. One or more protective locks can be hung on the padlock part 41 to improve the safety of the operator.

[0129] In addition to the above, in specific implementation, automatic position indicators can be set on the first shielding hole 311 and the second shielding hole 313 so that the operator can clearly obtain the position of the knob 3.

[0130] For example, the words "AUTO" or "Automatic Position" can be set on the first shielding hole 311. The words "Padlock Position" or a protective lock label can be set on the second shielding hole 313.

[0131] In some embodiments, the signal element may be one of a position switch, a limit switch, a micro switch, a magnetic switch, or a relay.

[0132] By using position switches, limit switches, micro switches, magnetic switches, or relays as signal elements, the mechanical rotation of the shaft can be converted into opening and closing control of signal element 5. This allows for a wider variety of signal elements 5, facilitating selection and configuration based on actual conditions.

[0133] When signal element 5 is a micro switch, one end of knob 3 can contact the spring of the micro switch. When knob 3 is rotated, a force is applied to the spring, causing the signal element to switch between a closed state and an open state.

[0134] In one possible implementation, the operation box also includes panel 6, such as Figure 1 As shown, panel 6 is mounted on base 1. Panel 6 and knob body 31 can be located on the same side of base 1.

[0135] The method by which the panel 6 is mounted on the base 1 is not specifically limited here. For example, the panel 6 can be mounted on the base 1 by means of snap-fit, riveting, or screw connection.

[0136] Please continue to refer to Figure 1 As shown, panel 6 has a through hole 61, a display hole 62 and an execution hole 63.

[0137] The through hole 61 corresponds to the padlock part 41. When the padlock part 4 is in the released position, the padlock part 41 protrudes from the side of the panel 6 away from the base 1, so that the operator can hang the protective lock on the padlock part 41. The structure and size of the through hole 61 are matched with the padlock part 41.

[0138] The display hole 62 corresponds to the operating end, allowing the operator to observe the specific position of the knob 3 through the panel 6. The structure and size of the display hole 62 are matched with the operating end.

[0139] The actuation hole 63 corresponds to the rotating part 34 of the knob 3, which allows the operator to directly access the rotating part 34 to rotate the knob 3. The structure and size of the actuation hole 63 are not compatible with the rotation.

[0140] The panel 6 protects the knob 3, improves the sealing of the control box, and effectively prevents external dust, iron filings, oil, moisture and other contaminants from entering the control box. This ensures that the control box can operate normally in harsh environments such as outdoors or chemical plants, and expands the scope of application of the control box.

[0141] At the same time, it can reduce the risk of operators or tools accidentally touching the exposed electrical contacts inside the control box, prevent equipment malfunction or electric shock caused by accidental contact, and improve electrical safety performance.

[0142] In one possible implementation, the orthographic projection of the padlock portion 41 onto the limiting portion 42 is located within the limiting portion 42 in the depth direction of the mounting groove 11. The dimension of the through hole 61 in the first direction is smaller than the dimension of the limiting portion 42. The first direction is perpendicular to the depth direction of the mounting groove 11.

[0143] At this time, when the padlock 4 is in the released position, the limiting part 42 can slide along the depth direction of the mounting groove 11 within the mounting groove 11, thereby synchronously driving the padlock part 41 to move away from the base 1. When the limiting part 42 is located at the opening of the mounting groove 11, the position of the limiting part 42 is limited by the knob body 31 and the cover. In this way, the limiting part 42 is prevented from sliding out of the mounting groove 11, enhancing the structural strength of the operating box.

[0144] In some embodiments, when the rotating shaft 2 rotates relative to the base 1, the rotating shaft 2 has an open position and an closed position. The operating terminal is provided with an indicator, which can be a line or an arrow, etc. The indicator corresponds to the display hole 62, meaning the indicator can be observed through the display hole 62.

[0145] Panel 6 has open and closed indicators. In practice, the open indicator can be "OFF", "Open", or "Disconnected". The closed indicator can be "ON", "Closed", or "Closed".

[0146] When shaft 2 is in the open position, the indicator corresponds to the open indicator. When shaft 2 is in the closed position, the indicator corresponds to the closed indicator.

[0147] The indicator rotates synchronously with the rotating shaft 2, forming a fixed angular correspondence with the indicator on the panel 6, so that there will be no misalignment or failure of the indicator.

[0148] When shaft 2 is in the open position, the indicator is facing the open indicator, and the operated component is in the open state. When shaft 2 is in the closed position, the indicator is facing the closed indicator, and the operated component is in the closed state.

[0149] In this way, operators can more intuitively determine whether the operated device is in the open or closed state, reducing the possibility of observation errors, perspective errors, and comprehension errors.

[0150] At the same time, it does not rely on power supply, indicator lights, or electrical signals, and can still indicate normally in the event of a fault, thus having a high level of safety.

[0151] In one possible implementation, a blocking part 43 is provided on the side of the limiting part 42 near the rotating shaft 2, such as... Figure 8 As shown.

[0152] like Figure 9 and Figure 10 As shown, the rotating shaft 2 is provided with a connected sliding groove 21 and a rotating groove 22. The rotating groove 22 is arranged along the circumference of the rotating shaft 2, and the sliding groove 21 is arranged along the axial direction of the rotating shaft 2.

[0153] Please combine Figures 8 to 10 As shown, when the padlock 4 is in the limit position, the blocking part 43 extends into the rotating groove 22, and the rotating shaft 2 can switch between the open position and the closed position.

[0154] When the padlock 4 is in the released position, the rotating shaft 2 is in the open position, and the blocking part 43 extends into the sliding groove 21 to prevent the rotating shaft 2 from switching from the open position to the closed position.

[0155] Thus, when the padlock 4 is in the limit position, the blocking part 43 extends into the rotating groove 22, and the rotating groove 22 provides clearance space for the circumferential rotation of the rotating shaft 2, so that the rotating shaft 2 can freely rotate and switch between the open position and the closed position without affecting the normal opening and closing operation of the operated component.

[0156] When the padlock 4 is in the released position, this is only allowed when the shaft 2 is in the open position.

[0157] At this time, the blocking part 43 extends into the sliding groove 21, which is provided along the axis of the rotating shaft 2. The axis of the rotating shaft 2 extends parallel to the depth direction of the mounting groove 11.

[0158] The padlock part 41 can slide relative to the base 1. At the same time, the blocking part 43 forms a circumferential rotation limit on the rotating shaft 2, preventing the rotating shaft 2 from switching from the open position to the closed position, realizing the mechanical locking of the operated component in the open state, ensuring that the operated component cannot be accidentally closed after padlocking, improving the safety and reliability of operation, and avoiding the safety risk of accidental closing after padlocking.

[0159] It should be noted that a bridging part is provided in the rotating groove 22, which allows the rotating shaft 2 to be in the open position. When the blocking part 43 extends into the rotating groove 22, it abuts against the bridging part to limit the blocking part 43 and ensure that the blocking part 43 can slide smoothly into the sliding groove 21.

[0160] In one example, the knob body 31 is provided with a protrusion 314, such as Figure 6 and Figure 7 As shown. In fact, there is a gap between the protrusion 314 and the knob body 31, which allows for elasticity between the protrusion 314 and the knob body 31. Under the action of external force, the protrusion 314 can move towards the knob body 31.

[0161] like Figure 5 As shown, the base 1 is provided with three limiting grooves 12 that mate with the protrusion 314. This allows for connection with... Figure 2 , Figures 5 to 7 As shown, when the knob 3 is in the automatic position, manual position, and padlock position, it corresponds to one of the three limit slots 12.

[0162] When the knob 3 is in the automatic, manual, and padlock positions, the protrusion 314 engages with the corresponding limit groove 12.

[0163] Thus, the base 1 is provided with three limiting grooves 12, which correspond to the automatic position, manual position and padlock position of the knob 3 respectively. The protrusion 314 on the knob 3 forms a positioning with the limiting groove 12, so that the knob 3 can achieve precise angle, no movement and no deviation in the three working positions, and avoid mode confusion caused by loose knob 3 or self-rotation.

[0164] Without any external force deliberately rotating the knob 3, the engaging force between the protrusion 314 and the limiting groove 12 can resist external interference such as vibration and collision, preventing the knob 3 from automatically switching positions during equipment operation, thereby reducing safety accidents caused by accidental switching of the knob 3 position.

[0165] In practical implementation, an arc-shaped protrusion can be provided on the base 1, and the axis of the arc-shaped protrusion can be collinear with the rotation axis 33 of the knob 3. When the knob 3 rotates relative to the base 1, the knob body 31 can abut against the arc-shaped protrusion.

[0166] In another example, the base 1 is provided with two support parts 13, such as Figure 5 As shown. When the knob 3 is in the automatic position, one of the support parts 13 is in support contact with the knob body 31, as shown. Figure 2 As shown.

[0167] When the knob 3 is in the padlock position, another support part 13 is in contact with the knob body 31.

[0168] Thus, the two support parts 13 respectively form mechanical stops for the automatic position and padlock position of the knob 3, limiting the maximum rotation range of the knob 3 and reducing the possibility of the knob 3 rotating too far, resulting in angular deviation, incorrect indication, or other phenomena.

[0169] When the knob 3 is in the automatic and padlock positions, the support part 13 provides a supporting force to the knob body 31. This ensures that the operating end of the knob 3 can be reliably blocked when it is in the automatic and padlock positions.

[0170] As one possible implementation method, refer to Figure 10 As shown, a first sealing groove 23 is provided on the rotating shaft 2 along the circumference of the rotating shaft 2. A first sealing ring (not shown in the figure) is fitted inside the first sealing groove 23. The outer surface of the first sealing ring is tightly fitted to the base 1.

[0171] This prevents dust, moisture, oil, corrosive gases, etc. from entering the operating box through the gap between the rotating shaft 2 and the base 1, significantly improving the dustproof, waterproof, and corrosion-resistant capabilities of the operating box and the operated parts, and extending the service life of the operating box.

[0172] The first sealing ring is fitted inside the first sealing groove 23, which provides a stable installation position for the first sealing ring to prevent it from shifting, misaligning, or even falling off. This ensures that the rotating shaft 2 and the base 1 maintain a uniform and tight seal during rotation, achieving both flexibility and reliability of the seal, and providing long-term sealing under dynamic operating conditions.

[0173] In practice, the outer surface of the first sealing ring is tightly fitted to the inner wall of the first mounting hole 15.

[0174] As another possible implementation, the knob 3 has a rotating shaft 33 with a circumferentially arranged second sealing groove 331. A second sealing ring is fitted inside the second sealing groove 331, and the outer surface of the second sealing ring is in close contact with the base 1.

[0175] This prevents dust, moisture, oil, corrosive gases, etc. from entering the operation box through the gap between the rotating shaft 33 and the base 1, significantly improving the dustproof, waterproof, and corrosion-resistant capabilities of the operation box and the operated parts, and extending the service life of the operation box.

[0176] The second sealing ring is fitted inside the second sealing groove 331, which provides a stable installation position for the second sealing ring to prevent it from shifting, misaligning, or even falling off. This ensures that the rotating shaft 33 and the base 1 maintain a uniform and sealed fit during the rotation of the knob 3, achieving both flexibility and reliable sealing of the rotating shaft 33, and providing long-lasting sealing under dynamic operating conditions.

[0177] In practice, the outer surface of the second sealing ring is in close contact with the inner wall of the second mounting hole 16.

[0178] In one example, the operating box also includes a baffle 7, such as Figure 3 As shown, the baffle 7 is located on the side of the base 1 away from the knob body.

[0179] The baffle 7 protects the signal element 5, improves the sealing of the control box, and effectively prevents external dust, iron filings, oil, moisture, etc., from entering the control box. This ensures the control box can operate normally in harsh environments such as outdoors or in chemical plants, expanding its applicability. Simultaneously, it improves the sealing performance of the operated components.

[0180] In addition, it can reduce the risk of operators or tools accidentally touching the signal element 5, prevent equipment malfunction or electric shock caused by accidental contact, and improve electrical safety performance.

[0181] In the description of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, "connection" or "joining" in mechanical structures can refer to a physical connection, such as a fixed connection, for example, a connection fixed by connecting parts, such as a connection fixed by screws, bolts, or other connecting parts; a physical connection can also be a detachable connection, such as a snap-fit ​​or interlocking connection; a physical connection can also be an integral connection, such as a connection formed by welding, bonding, or integral molding.
