[0080] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0081] Please refer to Figure 1-Figure 4 In this embodiment, an isolating switch mechanism 10 is provided. The isolating switch mechanism 10 can be applied to an isolating switch, and the isolating switch is applied to a circuit, and the isolating switch mechanism 10 can be used to operate the isolating switch to perform closing, opening, and grounding functions. When the isolating switch mechanism 10 performs closing, the circuit is turned on; when performing opening, the circuit is disconnected; when performing grounding, the circuit is grounded. Among them, the isolating switch mechanism 10 provided in this embodiment can improve the problem of low circuit safety factor in the prior art, that is, the isolating switch mechanism 10 can improve the safety of the circuit.

[0082] In this embodiment, the disconnector mechanism 10 includes a mounting bracket 11, an output shaft 12, a closing transition shaft 13, a positioning plate 17 and a linkage abutment mechanism 18. The output shaft 12 is rotatably connected to the mounting bracket 11 for performing closing, opening and grounding. The closing transition shaft 13 is rotatably arranged on the mounting bracket 11; the closing transition shaft 13 is transmission-connected to the output shaft 12. The positioning plate 17 is fixedly connected to the closing transition shaft 13 to rotate with the closing transition shaft 13; the radial outer periphery of the positioning plate 17 is provided with a first groove 171, a second groove 172 and a third groove 173. The linkage abutting mechanism 18 includes a linkage assembly 181, a abutting member 182 and a first elastic member 183; the abutting member 182 is connected to the first elastic member 183, and the abutting member 182 abuts against the outer periphery of the positioning plate 17, and when the output shaft 12 performs closing, opening and grounding respectively, the abutting member 182 abuts against the first groove 171, the second groove 172 and the third groove 173 respectively; specifically, when the output shaft 12 performs closing, opening and grounding, the abutting member 182 abuts against the bottom wall of the first groove 171; when the output shaft 12 performs opening, the abutting member 182 abuts against the bottom wall of the second groove 172; when the output shaft 12 performs grounding, the abutting member 182 abuts against the bottom wall of the third groove 173. In other words, when the abutment 182 abuts against the bottom wall of the first groove 171, it indicates that the circuit breaker is in place; when the abutment 182 abuts against the bottom wall of the second groove 172, it indicates that the circuit breaker is in place; when the abutment 182 abuts against the bottom wall of the third groove 173, it indicates that the circuit breaker is in place. In addition, the linkage assembly 181 is connected to the end of the abutment 182 away from the positioning plate 17, and is used to unlock the circuit breaker when the abutment 182 moves to the first groove 171, the second groove 172 or the third groove 173; and is also used to lock the circuit breaker when the abutment 182 moves to a position outside the first groove 171, the second groove 172 and the third groove 173 on the periphery of the positioning plate 17.

[0083] Among them, unlocking the circuit breaker means that the circuit breaker can be operated; while locking the circuit breaker means that the circuit breaker is locked and the operator cannot operate the circuit breaker.

[0084] As described above, in the isolating switch mechanism 10, the elastic action of the elastic member causes the abutting member 182 to abut against the outer periphery of the positioning plate 17, and can slide along the outer periphery of the positioning plate 17 during the rotation of the positioning plate 17, and abut against the first groove 171, the second groove 172, and the third groove 173 in sequence when the output shaft 12 is closed, opened, and grounded in sequence; and when the abutting member 182 abuts against the first groove 171, the second groove 172, and the third groove 173, it indicates that the closing, opening, and grounding are in place, and the circuit breaker can be unlocked by the linkage assembly 181, and the operator can safely operate the circuit breaker; on the contrary, if the abutting member 182 abuts against a position other than the first groove 171, the second groove 172, and the third groove 173 on the outer periphery of the positioning plate 17, it indicates that the closing, opening, or grounding is not in place, and the circuit breaker can be locked by the linkage assembly 181, and the operator cannot operate the circuit breaker, thereby avoiding safety accidents. Based on this, the isolating switch mechanism 10 can improve the problem of low circuit safety factor in the prior art.

[0085] At the same time, due to the elastic effect of the first elastic member 183, the abutting member 182 can be stably abutted against the outer periphery of the positioning plate 17, which can improve the stability of the abutting member 182 abutting against the positioning plate 17. Based on this, when the abutting member 182 abuts against the first groove 171, the second groove 172 or the third groove 173, the situation in which the abutting member 182 is shaken and withdraws from the first groove 171, the second groove 172 or the third groove 173 can be avoided, thereby ensuring the stability of the closing, opening and grounding in place.

[0086] Optionally, in this embodiment, the linkage abutting mechanism 18 further includes a fixing member 184, the fixing member 184 is fixedly connected to the mounting bracket 11, the first elastic member 183 is connected to the fixing member 184; the abutting member 182 passes through the fixing member 184 to be connected to the first elastic member 183. In this embodiment, the fixing member 184 is an inverted U-shaped structure, and the elastic member is arranged in the inner cavity formed by it. The abutting member 182 passes through the fixing member 184 and is connected to the first elastic member 183, and one end of the first elastic member 183 abuts on the fixing member 184; and the abutting member 182 is also provided with a protrusion that is inserted into the first elastic member 183, so that the abutting member 182 can drive the elastic member to produce elastic deformation during the movement, thereby providing a reinforcing force to the abutting member 182 to prevent the abutting member 182 from detaching from the positioning plate 17.

[0087] It should be understood that in other embodiments, other methods other than the fixing member 184 may be used to achieve connection of the elastic member.

[0088] Optionally, in this embodiment, the first elastic member 183 is a spring, and the first elastic member 183 is sleeved on the supporting member 182. In other embodiments, the first elastic member 183 may also be other types of elastic members, such as spring sheets or elastic ribs.

[0089] In this embodiment, the linkage assembly 181 includes a linkage rod 1811, a rotating member 1812 and a movable member 1813, wherein the movable member 1813 is connected to the supporting member 182 to move with the supporting member 182; the rotating member 1812 is rotatably connected to the mounting bracket 11, and a slide groove is provided at one end of the rotating member 1812, and the movable member 1813 is slidably disposed in the slide groove; the linkage rod 1811 is connected to the other end of the rotating member 1812, and the linkage rod 1811 is also used to connect with the circuit breaker to unlock and lock the circuit breaker when moving. When the output member rotates to make the supporting member 182 slide along the outer periphery of the positioning plate 17 to form a linear movement, the supporting member 182 drives the movable member 1813 to move, and the movable member 1813 slides in the slide groove. At the same time, it can drive the rotating member 1812 to rotate, and the rotating member 1812 transmits the power to the circuit breaker through the linkage rod 1811 to achieve unlocking and locking of the circuit breaker.

[0090] Please refer to Figure 5-Figure 7 In this embodiment, the disconnector mechanism 10 further includes a door locking mechanism 100. The door locking mechanism 100 includes a toggle member 110 and a first interlocking mechanism 120; the toggle member 110 is eccentrically arranged on the positioning plate 17 to rotate with the positioning plate 17; the first interlocking mechanism 120 is movably arranged on the mounting bracket 11, and the first interlocking mechanism 120 is used to connect with the door of the cable room where the disconnector mechanism 10 is located, and lock the door when the disconnector mechanism 10 is in a closed state or an open state; the interlocking mechanism has a trigger end 101, and the trigger end 101 is arranged on the rotation path of the toggle member 110; the trigger end 101 is used to be toggled by the toggle member 110 during the grounding process, and the first interlocking mechanism 120 unlocks the door after the output shaft 12 is grounded.

[0091] As described above, when the disconnector mechanism 10 is in the closed state or the open state, the first interlocking mechanism 120 locks the door; and in the process of grounding, the operator operates the closing operation shaft 14 to rotate, and the transmission structure transmits power to the output shaft 12 to realize the rotation of the output shaft 12, thereby realizing grounding. In the process of the output shaft 12 rotating, the closing transition shaft 13 is synchronously driven to rotate, and then the positioning plate 17 is driven to rotate, and the positioning plate 17 drives the toggle member 110 to rotate, so that in the process of grounding, the toggle member 110 can toggle the trigger end 101 to trigger the first interlocking mechanism 120 to unlock the door, thereby realizing the unlocking of the door of the cable room. In other words, when the isolating switch mechanism 10 is in the closed state or the open state, the door of the cable room cannot be opened, and the isolating switch mechanism 10 cannot be operated; and the door can only be opened to operate the isolating switch mechanism 10 when the isolating switch mechanism 10 is grounded, thereby preventing the operator from operating the isolating switch mechanism 10 in the closed state or the open state, effectively avoiding the risk of electric shock to the operator, and improving the operator's operating safety. Based on this, the isolating switch mechanism 10 provided in this embodiment can improve the problem of low safety in operating the isolating switch mechanism 10 in the prior art.

[0092] Optionally, in this embodiment, the first interlocking mechanism 120 includes a rotating part 121 and a connecting rod assembly 122; the rotating part 121 is rotatably connected to the mounting bracket 11, and the connecting rod assembly 122 is used to connect to the door; one end of the rotating part 121 forms the trigger end 101, and the other end is connected to the connecting rod assembly 122; when the trigger end 101 is toggled by the toggle member 110, the rotating part 121 drives the connecting rod assembly 122 to move to unlock the door.

[0093] That is to say, when the toggle member 110 drives the rotating part 121 to rotate, the rotating part 121 simultaneously drives the connecting rod assembly 122 to move, so that the power is transmitted to the locking structure of the door through the connecting rod assembly 122 to unlock the door.

[0094] Furthermore, in order to facilitate the locking of the door, in the present embodiment, the first interlocking mechanism 120 also includes a second elastic member 123, and the second elastic member 123 is connected to the rotating part 121. When the trigger end 101 is moved by the toggle member 110, the rotating part 121 drives the second elastic member 123 to move and generate elastic deformation; the second elastic member 123 is also used to drive the first interlocking mechanism 120 to reset when the toggle member 110 moves away from the trigger end 101, so as to achieve the locking of the door.

[0095] Specifically, during the grounding process, the toggle member 110 toggles the trigger end 101 to rotate the rotating part 121, and at the same time realizes the elastic deformation of the second elastic member 123; and when closing or opening the switch, the toggle member 110 moves away from the trigger end 101, and the force that inhibits the second elastic member 123 is cancelled. The second elastic member 123 drives the rotating part 121 to rotate and reset through its elastic recovery effect, and can transmit power to the connecting rod assembly 122 to realize automatic locking of the door. Based on this, the automatic locking of the door can be realized when closing and opening the switch, and the automatic unlocking of the door can be realized when grounding, which is convenient to operate and has high safety.

[0096] Optionally, in this embodiment, the second elastic member 123 may be a torsion spring, which is sleeved on the rotation center axis of the rotating portion 121. Of course, in other embodiments, the second elastic member 123 may also be other structures, for example, the rotating portion 121 and the mounting bracket 11 are connected by a flexible second elastic member 123, and the second elastic member 123 can be stretched during the rotation of the rotating portion 121, and when the toggle member 110 withdraws from the trigger end 101, the second elastic member 123 retracts to drive the rotating portion 121 to reset and rotate, and then the door is locked through the connecting rod assembly 122.

[0097] In this embodiment, the door locking mechanism 100 further includes a stopper 130, which is fixedly connected to the mounting bracket 11 and is located on the rotation path of the trigger end 101; the stopper 130 is used to abut the trigger end 101 after the first interlocking mechanism 120 is reset and moved and the door is locked. In the process of the second elastic member 123 driving the rotating part 121 to reset and rotate, the trigger end 101 rotates to abut against the stopper 130, completing the position limitation of the rotating part 121, which can not only prevent the rotating part 121 from rotating excessively, but also limit the rotating part 121 to a position that can cooperate with the toggle member 110, so that the toggle member 110 can drive the rotating part 121 to rotate during the grounding operation, so as to facilitate the subsequent door unlocking.

[0098] Optionally, in this embodiment, the toggle member 110 and the limit member 130 are both bolt structures, that is, the toggle member 110 is a bolt structure arranged on the positioning plate 17 by a threaded connection, and the limit member 130 is a bolt structure arranged on the mounting bracket 11 by a threaded connection.

[0099] Of course, in other embodiments, the toggle member 110 and the limiting member 130 may also be arranged in other ways, for example, the toggle member 110 and the positioning plate 17 are integrally formed; the limiting member 130 and the mounting bracket 11 are integrally formed, etc.

[0100] In this embodiment, the rotating portion 121 includes a first rotating connection portion 1211 and a trigger portion 1212; the middle portion of the first rotating connection portion 1211 is rotatably connected to the mounting bracket 11, and the trigger portion 1212 is disposed at one end of the first rotating connection portion 1211 and is disposed at an angle to the first rotating connection portion 1211, and the trigger portion 1212 forms the trigger end 101. Figure 8 In the case of an example, it can be seen that the trigger portion 1212 is a structure extending downward, which can facilitate the abutment between the toggle member 110 and the trigger portion 1212, and also facilitate the toggle member 110 to drive the rotating portion 121 to rotate.

[0101] In addition, the rotating portion 121 further includes an extension portion 1213, which is disposed at one end of the first rotating connection portion 1211 away from the trigger portion 1212 and is disposed at an angle to the first rotating connection portion 1211. The extension portion 1213 is connected to the connecting rod assembly 122. Figure 8 As an example, the extension portion 1213 extends upward to facilitate connection with the connecting rod assembly 122, thereby reducing the difficulty of assembly.

[0102] In this embodiment, the connecting rod assembly 122 includes at least one connecting rod 1221, one end of one connecting rod 1221 is connected to the rotating part 121, and one connecting rod 1221 is used to connect to the door. Figure 5 and Figure 6 In the example, the connecting rod 1221 structure includes only one connecting rod 1221, one end of which is connected to the rotating part 121, and the other end is used to connect the locking structure of the door. In other embodiments of the present invention, the connecting rod assembly 122 may also include multiple connecting rods 1221, and the multiple connecting rods 1221 may form a multi-connecting rod 1221 structure to realize the driving of the door locking structure.

[0103] In this embodiment, the positioning disk 17 is disk-shaped, and the toggle member 110 is convexly arranged on one side in the thickness direction of the positioning disk 17. Setting the positioning disk 17 in a disk shape can reduce the space occupied by the positioning disk 17 in the mounting bracket 11, which is conducive to the miniaturization of the isolating switch mechanism 10, reduces the space requirement of the isolating switch mechanism 10, and further makes the isolating switch mechanism 10 not limited by the installation space, thereby achieving the purpose of increasing the application scenarios of the isolating switch mechanism 10.

[0104] In this embodiment, the transmission structure is a gear structure. The transmission connection between the closing operation shaft 14 and the output shaft 12 is achieved by gear meshing, which can ensure the stability of the transmission connection on the one hand, and on the other hand, due to the higher stability of the gear transmission, the closing, opening and grounding operations can be completed more accurately, and the interlocking of the door can be accurately achieved at the same time.

[0105] Please refer to Figure 9-11 In this embodiment, the isolating switch mechanism 10 also includes an in-position limiting mechanism 200; the in-position limiting mechanism 200 includes a positioning member 210, a first positioning member 220 and a second positioning member 230; the positioning member 210 is rotatably connected to the closing transition shaft 13 to rotate with the closing transition shaft 13; the first positioning member 220 and the second positioning member 230 are both arranged on the mounting bracket 11, and are both located on the rotation path of the positioning member 210, and a gap is formed between the first positioning member 220 and the second positioning member 230; the positioning member 210 is used to respectively abut against the first positioning member 220 and the second positioning member 230 when the output shaft 12 rotates to closing and grounding.

[0106] As described above, in the isolating switch mechanism 10 provided in the present embodiment, the closing position or grounding position is judged by the way that the positioning member 210 abuts against the first positioning member 220, which can facilitate the operator to judge whether the closing operation and the grounding operation are in place. Moreover, it is precisely because of the position stability of the first positioning member 220 that the stability of the matching position of the positioning member 210 and the first positioning member 220 can be ensured, and the matching position of the closing operation or the grounding operation can be ensured to be stable, thereby effectively realizing the closing operation or the grounding operation, avoiding the problem of the closing or the grounding not being in place, and improving the circuit stability, thereby improving the circuit safety. Based on this, the isolating switch mechanism 10 provided in the present embodiment can improve the problem of low circuit stability leading to reduced safety in the prior art. Similarly, in the case of setting the second positioning member 230, the first positioning member 220 and the second positioning member 230 can respectively realize the positioning of the closing position and the grounding position, ensuring the precise position of the closing function and the grounding function, and ensuring the overall stability of the circuit and the circuit safety.

[0107] Optionally, an eccentric first rotating shaft 221 is provided on the first positioning member 220, and the first rotating shaft 221 is rotatably connected to the mounting bracket 11; an eccentric second rotating shaft 231 is provided on the second positioning member 230, and the second rotating shaft 231 is rotatably connected to the mounting bracket 11. Even if the first positioning member 220 or the positioning member 210 is offset, the position of the first positioning member 220 on the mounting bracket 11 can be adjusted by the eccentric rotation of the first positioning member 220, so that the first positioning member 220 is adjusted to a position where the switch is in place or the ground is in place in cooperation with the positioning member 210, thereby avoiding the problem of inadequate closing or inadequate grounding, and achieving the purpose of improving circuit stability and circuit safety.

[0108] It should be noted that since the first rotating shaft 430 is eccentrically arranged relative to the first positioning member 220, the first positioning member 220 will move in the radial direction during the process of rotating around the first rotating shaft 430, so that the position when it is abutting against the positioning member 210 can be adjusted. The position of the first positioning member 220 can be adjusted based on actual conditions to facilitate adjusting the first positioning member 220 to a suitable position, so that the first positioning member 220 is in a closed position or a grounded position when abutting against the positioning member 210.

[0109] Similar to the first positioning member 220, even if the second positioning member 230 or the positioning member 210 is offset, the position of the second positioning member 230 on the mounting bracket 11 can be adjusted by eccentric rotation of the second positioning member 230, thereby adjusting the second positioning member 230 to a position where it cooperates with the positioning member 210 to achieve the closing position or the grounding position, thereby avoiding the problem of inadequate closing or inadequate grounding, and achieving the purpose of improving circuit stability and circuit safety.

[0110] Similarly, since the second rotating shaft is eccentrically arranged relative to the second positioning member 230, the second positioning member 230 will move in the radial direction during the process of rotating around the second rotating shaft, and the position when it is abutting against the positioning member 210 can be adjusted. The position of the second positioning member 230 can be adjusted based on actual conditions to facilitate adjusting the second positioning member 230 to a suitable position, so that the second positioning member 230 is in a closed position or a grounded position when abutting against the positioning member 210.

[0111] Optionally, a fourth groove 211 and a fifth groove 212 are respectively provided on two opposite sides of the positioning member 210. When the positioning member 210 is abutted against the first positioning member 220, the first positioning member 220 is located in the fourth groove 211, and the opening width of the fourth groove 211 is greater than the diameter of the first positioning member 220; when the positioning member 210 is abutted against the second positioning member 230, the second positioning member 230 is located in the fifth groove 212, and the opening width of the fifth groove 212 is greater than the diameter of the second positioning member 230.

[0112] Accommodating the first positioning member 220 inside the fourth groove 211 can increase the contact area between the first positioning member 220 and the positioning member 210, thereby improving the abutment stability between the first positioning member 220 and the positioning member 210, ensuring the relative position stability of the first positioning member 220 and the positioning member 210 after the switch is closed or grounded, thereby ensuring the stability of the circuit in the closed state or the grounded state, and improving the stability and safety of the circuit.

[0113] Furthermore, the opening width of the fourth groove 211 is greater than the diameter of the first positioning member 220. It is worth noting that after the first positioning member 220 rotates with the first rotating shaft 430, the position of the first positioning member 220 will change. At this time, the position of the first positioning member 220 corresponding to the fourth groove 211 will change. Setting the opening width of the fourth groove 211 to be greater than the diameter of the first positioning member 220 can ensure that after the position of the first positioning member 220 is adjusted, when the switch is in the closed position or the grounding position is in the closed position, the first positioning member 220 can still be accommodated in the fourth groove 211, so as to facilitate the mutual cooperation between the first positioning member 220 and the positioning member 210.

[0114] Similarly, accommodating the second positioning member 230 inside the fifth groove 212 can increase the contact area between the second positioning member 230 and the positioning member 210, thereby improving the abutment stability between the second positioning member 230 and the positioning member 210, ensuring the relative position stability of the second positioning member 230 and the positioning member 210 after the switch is closed or grounded, thereby ensuring the stability of the circuit in the closed state or the grounded state, and improving the stability and safety of the circuit.

[0115] Optionally, the opening width of the fifth groove 212 is greater than the diameter of the second positioning member 230. It is worth noting that after the second positioning member 230 rotates about the second rotation axis, the position of the second positioning member 230 will change. At this time, the position of the second positioning member 230 corresponding to the fifth groove 212 will change. Setting the opening width of the fifth groove 212 to be greater than the diameter of the second positioning member 230 can ensure that after the position of the second positioning member 230 is adjusted, when the switch is in the closed position or the grounding position is in the closed position, the second positioning member 230 can still be accommodated in the fifth groove 212, so as to facilitate the mutual cooperation between the second positioning member 230 and the positioning member 210.

[0116] Please refer to Figure 12-14 Optionally, the isolating switch mechanism 10 further includes a micro switch group 300, which includes a cam structure 310, a closing micro switch 320, an opening micro switch 330 and a grounding micro switch 340; the cam structure 310 is fixedly arranged on the grounding transition shaft 16 to rotate with the grounding transition shaft 16; the cam structure 310 has a raised abutting portion 311; the closing micro switch 320, the opening micro switch 330 and the grounding micro switch 340 are arranged around the cam structure 310;

[0117] The closing micro switch 320 has a first trigger switch 321 on the side facing the cam structure 310; when the output shaft 12 is closed, the abutting portion 311 abuts against the first trigger switch 321; the closing micro switch 320 is configured to send a first electrical signal when the first trigger switch 321 is abutted, and the first electrical signal is used to indicate that the isolating switch mechanism 10 is in the closed state. The grounding micro switch 340 has a second trigger switch 331 on the side facing the cam structure 310; when the output shaft 12 is grounded, the abutting portion 311 abuts against the second trigger switch 331; the grounding micro switch 340 is configured to send a second electrical signal when the second trigger switch 331 is abutted, and the second electrical signal is used to indicate that the isolating switch mechanism 10 is in the grounding state. The opening micro switch 330 has a third trigger switch 341 on the side facing the cam structure 310; when the output shaft 12 performs opening, the abutment portion 311 abuts against the third trigger switch 341; the opening micro switch 330 is configured to emit a third electrical signal when the third trigger switch 341 is abutted, and the third electrical signal is used to indicate that the isolating switch mechanism 10 is in the opening state.

[0118] As described above, when the isolating switch mechanism 10 executes closing, the output shaft 12 rotates relative to the mounting bracket 11, and the closing is executed through the output shaft 12. At the same time, the output shaft 12 drives the cam structure 310 to rotate, and can synchronously drive the supporting portion 311 to rotate; after the isolating switch mechanism 10 completes the closing action, the supporting portion 311 is supported on the first trigger switch 321 of the closing microswitch 320, thereby triggering the closing microswitch 320 to send a first electrical signal. The operator can judge that the isolating switch mechanism 10 has completed the closing based on the first electrical signal, and can accurately judge that the isolating switch mechanism 10 has been closed. Based on this, the isolating switch mechanism 10 can improve the problem in the prior art that the operator cannot accurately judge whether the closing is in place, resulting in safety hazards. Furthermore, a closing micro switch 320, a grounding micro switch 340 and an opening micro switch 330 are simultaneously arranged on the mounting bracket 11, so as to respectively send out a first electrical signal, a second electrical signal and a third electrical signal when closing, opening and grounding, and the control device can be used to receive the first electrical signal, the second electrical signal and the third electrical signal, and can respectively send out corresponding prompt signals when receiving the first electrical signal, the second electrical signal and the third electrical signal, so as to prompt the operator that the operation is in place. Therefore, based on the arrangement of the closing micro switch 320, the opening micro switch 330 and the grounding micro switch 340, the operator can be helped to accurately judge whether the closing, opening and grounding are in place, thereby avoiding the problem of forming a potential safety hazard caused by inaccurate judgment.

[0119] In this embodiment, the closing micro switch 320, the grounding micro switch 340 and the opening micro switch 330 are arranged around the cam structure 310, and the opening micro switch 330 is located between the closing micro switch 320 and the grounding micro switch 340. When the grounding operation shaft 15 or the closing operation shaft 14 is operated, the output shaft 12 is output with power so that the output shaft 12 rotates, and the output shaft 12 can respectively realize closing, opening and grounding when rotating at different angles. Based on this, the closing micro switch 320, the grounding micro switch 340 and the opening micro switch 330 are respectively arranged at different positions and arranged around the cam structure 310, which can correspond to the positions where the output shaft 12 performs different functions, so that the output shaft 12 can respectively resist the closing micro switch 320, the opening micro switch 330 and the grounding micro switch 340 through the resisting portion 311 when closing, opening and grounding.

[0120] Generally, within the rotation range of the output shaft 12, the closing position and the grounding position are located at the two ends of the range, while the opening position is located in the middle of the range. Based on this, the opening microswitch 330 is arranged in the middle of the closing microswitch 320 and the grounding microswitch 340 to achieve a one-to-one correspondence between the closing position, the opening position and the grounding position and the closing microswitch 320, the opening microswitch 330 and the grounding microswitch 340 respectively.

[0121] In this embodiment, please refer to Fig.13 and Fig.14 The outer periphery of the abutting portion 311 has an abutting surface 3111 and two guide surfaces 3112; in the rotation direction of the abutting portion 311, the two guide surfaces 3112 are respectively located on both sides of the abutting surface 3111, and an arc transition surface is provided between the guide surface 3112 and the abutting surface 3111. The provision of the arc transition surface facilitates the smooth sliding of the first trigger switch 321 between the guide surface 3112, the arc transition surface and the abutting surface 3111, ensuring that the closing micro switch 320, the opening micro switch 330 and the grounding micro switch 340 are not damaged, thereby extending the service life of the closing micro switch 320, the opening micro switch 330 and the grounding micro switch 340.

[0122] Among them, taking the cooperation between the supporting portion 311 and the first trigger switch 321 as an example for explanation, when the cam structure 310 rotates following the output shaft 12, the supporting portion 311 first contacts the first trigger switch 321 through one of the guide surfaces 3112; as the cam structure 310 continues to rotate, the first trigger switch 321 slides on the guide surface 3112 and gradually approaches the supporting surface 3111. At the same time, since the supporting portion 311 is in a convex state, it will gradually press down the first trigger switch 321; and when the cam structure 310 rotates until the supporting surface 3111 contacts the first trigger switch 321, the degree of pressing down the first trigger switch 321 is the highest, thereby realizing the triggering of the closing microswitch 320, and the closing microswitch 320 sends out a first electrical signal. In the process from closing to opening, the first trigger switch 321 moves out from the abutting surface 3111, moves to the guide surface 3112, and gradually moves away from the abutting surface 3111, so that the first trigger switch 321 gradually returns to its original state until the abutting portion 311 is completely separated from the first trigger switch 321. Similarly, when the second trigger switch 331 and the third trigger switch 341 are pressed down or disengaged, the cam structure 310 and the abutting portion 311 perform the same actions as above, which will not be repeated here.

[0123] Optionally, in this embodiment, the cam structure 310 includes an integrally formed main body 312 and abutting portion 311, the butting portion 311 is disposed on one side of the main body 312, the cross-sectional outer contour of the main body 312 is circular, and the guide surface 3112 is tangent to the outer side surface of the main body 312. In this embodiment, the main body 312 is sleeved on the ground transition shaft 16, and the butting portion 311 is disposed on the outer side of the main body 312. In order to ensure the synchronization of the rotation of the main body 312 and the ground transition shaft 16, the cross-section of the inner contour of the main body 312 is non-circular, and similarly, the cross-section of the part of the ground transition shaft 16 that matches the main body 312 is non-circular, and the two have the same shape. In this embodiment, the cross-section of the inner contour of the main body 312 presents a shape composed of two arcs and two straight lines; similarly, the outer contour of the cross-section of the ground transition shaft 16 presents a shape formed by two arcs and two straight lines. It should be understood that in other embodiments, the main body 312 and the ground transition shaft 16 can also adopt other shapes. In addition, making the guide surface 3112 tangent to the outer contour of the main body 312 can facilitate the production of the cam structure 310 on the one hand, and on the other hand, if the first trigger switch 321 contacts the outer contour of the main body 312, it can also facilitate the first trigger switch 321 to move smoothly onto the guide surface 3112.

[0124] Optionally, see Figure 15-18The isolating switch mechanism 10 also includes a handle locking mechanism 400, a first operating handle 410 and a second operating handle; the handle locking mechanism 400 includes a first rotating shaft 430 and a locking member 440; the first rotating shaft 430 is rotatably connected to the mounting bracket 11, and the first rotating shaft 430 is transmission-connected to the grounding transition shaft 16, the locking member 440 is arranged on the first rotating shaft 430 and can rotate with the first rotating shaft 430; the radial outer periphery of the locking member 440 is provided with a first limiting portion 441 and a first avoidance groove 442 and a second avoidance groove 443 located on both sides of the first limiting portion 441. Among them, the first operating handle 410 is used to be detachably connected to the closing operating shaft 14, so as to drive the closing operating shaft 14 to rotate to the first state to achieve closing, and is also used to drive the closing operating shaft 14 to rotate to the second state to achieve opening. A first annular groove 411 is provided on the first operating handle 410. When the closing operating shaft 14 rotates to a state between the first state and the second state, the first limit portion 441 is screwed into the first annular groove 411; when the closing operating shaft 14 is in the first state, the first operating handle 410 corresponds to the first avoidance groove 442 to avoid the first operating handle 410 from being removed; when the closing operating shaft 14 is in the second state, the first operating handle 410 corresponds to the second avoidance groove 443 to avoid the first operating handle 410 from being removed. The grounding operating shaft is used to be detachably connected to the grounding operating shaft 15, so as to drive the grounding operating shaft 15 to rotate to the third state to achieve grounding; a second annular groove is provided on the second operating handle; a second limiting portion 444 is also provided on the radial outer periphery of the locking member 440, and the second limiting portion 444 and the first limiting portion 441 are respectively located on both sides of the first avoidance groove 442; the second limiting portion 444 is used to screw into the second annular groove during the process of the grounding operating shaft 15 rotating to the third state, and when the grounding operating shaft 15 rotates to the third state, the first avoidance groove 442 corresponds to the second operating handle to avoid the second operating handle from being removed.

[0125] In the disconnector mechanism 10, during the closing operation, the first operating handle 410 is mounted on the closing operating shaft 14, and the closing operating shaft 14 is driven to rotate by rotating the first operating handle 410, and the closing operating shaft 14 drives the output shaft 12 to rotate to achieve closing and opening. When the output shaft 12 rotates, the grounding transition shaft 16 can be driven to rotate, thereby driving the first rotating shaft 430 to rotate through the grounding transition shaft 16, and the first rotating shaft 430 drives the locking member 440 to rotate. During the process of the closing operation shaft 14 rotating from the second state to the first state, since the first limit portion 441 is screwed into the first annular groove 411, the first operating handle 410 cannot be removed from the closing operation shaft 14; that is, before the closing operation is in place, the first operating handle 410 cannot be pulled out, and only when the closing operation shaft 14 rotates to the first state to achieve the closing operation in place, the first avoidance groove 442 corresponds to the first operating handle 410 to avoid the first operating handle 410 from being removed; similarly, only when the closing operation shaft 14 rotates from the first state to the second state and the opening operation is completed, the second avoidance groove 443 corresponds to the first operating handle 410 to avoid the first operating handle 410 from being removed. Based on this, in the disconnector mechanism 10, the first operating handle 410 can be removed only when the closing operation is in place or the opening operation is in place, which can facilitate the operator to judge whether the operation is in place on the one hand, and can also provide a foolproof effect to avoid the situation where the first operating handle 410 is removed when the operation is not in place. Based on this, the isolating switch mechanism 10 provided by the present invention can improve the technical problem in the prior art that improper operation may affect the normal operation of the circuit.

[0126] Similarly, during the grounding operation of the second operating handle, if the grounding operating shaft 15 does not rotate to the third state, it means that the grounding is not in place. At this time, the second limit portion 444 is screwed into the second ring groove, so that the second operating handle cannot be removed; until the grounding operating shaft 15 rotates to the third state, indicating that the grounding is in place, the first avoidance groove 442 can correspond to the second operating handle, and the second operating handle can be removed. It can also prevent fooling and facilitate the operator to judge whether the grounding is in place.

[0127] It should be noted that, in some embodiments, the first operating handle 410 and the second operating handle can be the same operating handle. Based on this, when closing or opening the switch, the grounding operation cannot be performed at the same time, which can play a fool-proof role and avoid operator errors.

[0128] In this embodiment, the diameter of the circular path where the inner wall of the first avoidance groove 442 is located is greater than the diameter of the first operating handle 410. Based on this, when the closing operation shaft 14 rotates to the first state to achieve the closing position, a certain gap can be formed between the inner wall of the first avoidance groove 442 and the outer side of the first operating handle 410, which facilitates the removal of the first operating handle 410 and reduces the difficulty of removal. Similarly, the diameter of the circular path where the inner wall of the first avoidance groove 442 is located is also greater than the diameter of the second operating handle, so as to facilitate the removal of the second operating handle when the grounding is in place.

[0129] In addition, the handle locking mechanism 400 further includes a third position member 450, which is connected to the first rotating shaft 430 to rotate with the first rotating shaft 430. When the closing operating shaft 14 rotates to the second state, the third position member 450 abuts against the outer periphery of the first operating handle 410. When the closing operating shaft 14 rotates to the second state, the third position member 450 abuts against the outer periphery of the first operating handle 410. That is to say, during the opening operation, the operator can judge whether the opening operation is in place based on whether the third positioning member 450 is against the first operating handle 410; when the third positioning member 450 is against the first operating handle 410, it means that the second avoidance groove 443 corresponds to the second operating handle and the opening is in place, and the first operating handle 410 can be directly disassembled at this time; if the third positioning member 450 is not against the first operating handle 410, at this time, the first operating handle 410 can still be rotated, and the first limiting portion 441 is still located in the first annular groove 411, which means that the first operating handle 410 cannot be removed, which can also play a fool-proof role.

[0130] In addition, in this embodiment, the handle limit assembly further includes a gasket 460, which is disposed between the third position member 450 and the locking member 440. Generally, in order to facilitate the locking member 440 to be inserted into the first annular groove 411 and the second annular groove, the width of the first annular groove 411 and the width of the second annular groove are slightly greater than the thickness of the locking member 440. At this time, by providing the gasket 460, a certain distance can be ensured between the locking member 440 and the third position member 450, so as to prevent the third position member 450 from being inserted into the first annular groove 411 or the second annular groove during the rotation process, resulting in the failure to achieve the holding effect of the gate opening position.

[0131] Furthermore, the locking member 440, the third positioning member 450 and the gasket 460 are all in sheet shape, and the area of ​​the gasket 460 is smaller than that of the third positioning member 450, and the area of ​​the gasket 460 is smaller than that of the locking member 440. Thus, the gasket 460 can be completely covered by the locking member 440 and the third positioning member 450 to prevent the gasket 460 from being stuck in the first annular groove 411 or the second annular groove, and the gasket 460 can also be prevented from abutting against the first operating handle 410.

[0132] Optionally, see Figure 19-21 The isolating switch mechanism 10 also includes a shell and an indicating device 500. The shell is provided with an observation hole, and the mounting bracket 11 is arranged inside the shell. The indicating device 500 includes an indicating disk 510, and the indicating disk 510 is rotatably connected to the mounting bracket 11 through a second rotating shaft 520; and the second rotating shaft 520 is transmission-connected to the output shaft 12; the upper surface of the indicating disk 510 is provided with a first area 511, a second area 512 and a third area 513 spaced apart. When the output shaft 12 is closed, the first area 511 is exposed from the observation hole; when the output shaft 12 is opened, the second area 512 is exposed from the observation hole; when the output shaft 12 is grounded, the third area 513 is exposed from the observation hole. Among them, Fig.19 The dotted lines in are only used to conveniently distinguish the first area 511 , the second area 512 , and the third area 513 .

[0133] As described above, in the isolating switch mechanism 10, when the output shaft 12 is used to close, open, and ground, if the closing is in place, the first area 511 of the indicator plate 510 can be exposed from the observation hole; if the opening is in place, the second area 512 of the indicator plate 510 can be exposed from the observation hole; if the grounding is in place, the third area 513 of the indicator plate 510 can be exposed from the observation hole. Based on this, the operator can judge the state of the isolating switch mechanism 10 based on the area on the indicator plate 510 exposed from the observation hole, and can also judge whether the operation of the isolating switch mechanism 10 is in place based on the part of the indicator plate 510 exposed from the observation hole. Based on this, the isolating switch mechanism 10 provided by the present invention can improve the problem that the isolating switch mechanism 10 in the prior art is inconvenient to judge the state and whether the operation is in place.

[0134] Optionally, to facilitate operator judgment, in the present embodiment, a first indication portion 5111 is provided on the first area 511; a second indication portion 5121 is provided on the second area 512; a third indication portion 5131 is provided on the third area 513; the first indication portion 5111, the second indication portion 5121 and the third indication portion 5131 are different from each other.

[0135] The first indicator 5111, the second indicator 5121 and the third indicator 5131 can be distinguished not only by graphics of different shapes, but also by different colors and different material compositions, etc., so that the operator can accurately judge the state of the disconnector mechanism 10.

[0136] Optionally, when the first area 511 is exposed from the observation hole, the indicator disk 510 covers the grounding operation shaft 15; when the third area 513 is exposed from the observation hole, the indicator disk 510 covers the closing operation shaft 14; when the second area 512 is exposed from the observation hole, the indicator disk 510 avoids the grounding operation shaft 15 and the closing operation shaft 14. In other words, when the switch is in full swing, the indicator disk 510 blocks the grounding operation shaft 15, and the operator cannot directly operate the grounding operation; if the operator needs to operate the grounding operation shaft 15, the output shaft 12 needs to be rotated to the open state, and then the grounding operation shaft 15 can be avoided. Correspondingly, when the third area 513 is exposed from the observation hole, the indicator disk 510 blocks the closing operation shaft 14, and the operator cannot directly operate the closing operation shaft 14, and the grounding needs to be released first, so that the indicator disk 510 avoids the closing operation shaft 14. On the one hand, it can prevent damage to the equipment caused by operating grounding in the closed state, and on the other hand, it can also avoid risks such as electric shock to the operator.

[0137] Optionally, see Fig. 22 and Fig.23 The isolating switch mechanism 10 also includes an operating hole shielding mechanism 600, which includes a shielding plate 610 and a second linkage mechanism 620; the shielding plate 610 is rotatably arranged on the top of the output shaft 12 and can rotate freely relative to the output shaft 12; the second linkage mechanism 620 is connected to the shielding plate 610 and is used to be connected to the circuit breaker; the second linkage mechanism 620 is used to be pulled when the circuit breaker is closed and opened, and when the circuit breaker is closed, the shielding plate 610 is driven to block and rotate to above the closing operation shaft 14 and the grounding operation shaft 15 to shield the closing operation shaft 14 and the grounding operation shaft 15, and when the circuit breaker is opened, the shielding plate 610 is driven to rotate to stagger the closing operation shaft 14 and the grounding operation shaft 15 to avoid the closing operation shaft 14 and the grounding operation shaft 15.

[0138] It should be noted that in the disconnector mechanism 10, the closing operation shaft 14 and the grounding operation shaft 15 are both located inside the disconnector mechanism 10, and an operation hole for the operating mechanism to penetrate is provided on the disconnector mechanism 10. When the operating mechanism penetrates from the operation hole, it can cooperate with the closing operation shaft 14 or the grounding operation shaft 15 to achieve the driving of the closing operation shaft 14 and the grounding operation shaft 15 by applying force to the operating mechanism. Among them, the closing operation shaft 14 and the grounding operation shaft 15 are provided with operation holes in a one-to-one correspondence.

[0139] That is to say, the second linkage mechanism 620 can change the state of the baffle 610 based on the action of the circuit breaker, so as to open the operating hole corresponding to the closing operating shaft 14 when the circuit breaker is opened, and to block the operating hole corresponding to the closing operating shaft 14 when the circuit breaker is closed.

[0140] As described above, when the operating hole shielding structure is applied to the isolating switch mechanism 10, since the second linkage mechanism 620 is connected to the circuit breaker, and when the circuit breaker is closed, the shielding plate 610 is driven to rotate by the second linkage mechanism 620 to shield the closing operation shaft 14 through the shielding plate 610, the operating hole corresponding to the closing operation shaft 14 on the isolating switch mechanism 10 can be shielded, and the operator can be prevented from inserting the operating mechanism to operate the closing operation shaft 14 when the circuit breaker is closed, and the operator can be prevented from operating the isolating switch mechanism 10 when the circuit breaker is closed, so as to avoid electric shock to the user. On the one hand, it can play a role in preventing stupidity, and on the other hand, it can also improve the circuit safety. Based on this, the operating hole shielding structure can improve the problem of low circuit safety in the prior art.

[0141] Furthermore, the shielding plate 610 can simultaneously block the two operating holes corresponding to the closing operating shaft 14 and the grounding operating shaft 15 when the circuit breaker is closed, so that the operator cannot insert the operating mechanism into the operating hole to operate the closing operating shaft 14 and the grounding operating shaft 15, thereby avoiding the risk of electric shock to the operator and playing a fool-proof role; at the same time, it also further improves the safety of the circuit.

[0142] In this embodiment, the shielding plate 610 includes a second rotating connection portion 611, a first shielding portion 612, and a second shielding portion 613. The first shielding portion 612 and the second shielding portion 613 are both connected to the second rotating connection portion 611, the first shielding portion 612 is used to shield the closing operation shaft 14 when the circuit breaker is closed, and the second shielding portion 613 is used to shield the grounding operation shaft 15 when the circuit breaker is closed. The portions of the shielding plate 610 used to shield the closing operation shaft 14 and the grounding operation shaft 15 are separately provided, so that redundant structures can be omitted. On the one hand, the structure of the disconnector mechanism 10 can be avoided from being too complicated. On the other hand, the area of ​​the shielding plate 610 can be reduced, thereby reducing the area of ​​the disconnector mechanism 10 shielded by the shielding plate 610, which is convenient for the inspection and maintenance of the disconnector mechanism 10.

[0143] Further, in order to facilitate the first shielding portion 612 and the second shielding portion 613 to synchronously shield the two operating holes, in this embodiment, the first shielding portion 612 extends along the first straight line, the second shielding portion 613 extends along the second straight line, and the first straight line and the second straight line are arranged at an angle. In the case of taking the figure as an example, it can be seen that the second rotating connection portion 611 is the part where the first shielding portion 612 and the second shielding portion 613 intersect, and the first shielding portion 612, the second shielding portion 613 and the second rotating connection portion 611 together form a V shape.

[0144] It should be understood that in other embodiments of the present invention, the arrangement of the first shielding portion 612 and the second shielding portion 613 may also be adjusted according to actual conditions. For example, in order to facilitate the first shielding portion 612 or the second shielding portion 613 to avoid the components in the disconnector mechanism 10, the first shielding portion 612 or the second shielding portion 613 may also be arranged to extend along an arc path.

[0145] In this embodiment, the second rotating connection part 611, the first blocking part 612 and the second blocking part 613 are integrally formed. The integrally formed method can reduce the difficulty of production and thus reduce the production cost. The second rotating connection part 611, the first blocking part 612 and the second blocking part 613 can be formed by cutting or casting.

[0146] Of course, in other embodiments, the first shielding portion 612 and the second shielding portion 613 may also be fixed to the second rotating connection portion 611 in other ways, such as welding, bonding, or screw connection.

[0147] In this embodiment, the second rotating connection part 611, the first shielding part 612 and the second shielding part 613 are all in sheet shape, and the second rotating connection part 611, the first shielding part 612 and the second shielding part 613 are located in the same plane. This can reduce the space occupied by the shielding plate 610 in the isolating switch mechanism 10, thereby facilitating the miniaturization of the isolating switch mechanism 10.

[0148] In addition, in the present embodiment, the shielding plate 610 further includes a connecting portion 614, the connecting portion 614 includes an extension section 6141 and a connecting section 6142, the extension section 6141 is connected to the second rotating connecting portion 611, and extends out along a straight line that forms an angle with the plane where the second rotating connecting portion 611 is located, the connecting section 6142 is provided at the end of the extension section 6141 away from the second rotating connecting portion 611, and the second linkage mechanism 620 is connected to the connecting section 6142. By extending the connecting section 6142 to a situation where it is not coplanar with the first shielding portion 612 and the second shielding portion 613 through the extension section 6141, the phenomenon of interference between the second linkage mechanism 620 and the first shielding portion 612 or the second shielding portion 613 during the rotation of the shielding plate 610 can be avoided, and the shielding plate 610 can be prevented from being damaged and causing failure.

[0149] Preferably, the extension section 6141 is perpendicular to the second rotating connection part 611, and the connection section 6142 is arranged parallel to the second rotating connection part 611. On the one hand, the space occupied by the shielding plate 610 as a whole can be reduced, and on the other hand, the difficulty of making the connection part 614 can be reduced, thereby achieving the purpose of reducing costs.

[0150] Furthermore, the connecting portion 614 and the second rotating connecting portion 611 are integrally formed, so that the shielding plate 610 is integrally formed as a whole, which can reduce the manufacturing difficulty and the manufacturing cost.

[0151] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
