Description

Technical Field

[0001] This utility model relates to the field of low-voltage devices, and in particular to an operating mechanism and a rotary switch. Background Technology

[0002] Rotary switches are widely used in various electrical systems, such as power systems and industrial production lines. In low-voltage circuits, rotary switches can quickly and safely cut off or restore current, providing a clear point of interruption, thereby effectively preventing electrical accidents caused by misoperation.

[0003] Most existing rotary switches rely on manual operation to open and close circuits. However, with the increasing prevalence of intelligent electrical applications, the requirements for switch functionality and safe operation are becoming more stringent, especially in photovoltaic power plants. Photovoltaic power plants are large and geographically dispersed. As rotary disconnect switches are designed to cut off faulty circuits to ensure electrical safety and personal safety, in situations like a fire involving photovoltaic modules, it's crucial to shut off the circuit promptly to minimize damage. Manual operation makes it difficult to achieve this rapid circuit disconnection and ensure personal safety.

[0004] Therefore, developing switches with free tripping capabilities and the ability to automatically drive the circuit to disconnect has become an important direction. At the same time, rotary switches should also be compact in structure and have minimal size increase to ensure adaptability. Utility Model Content

[0005] The purpose of this utility model is to overcome the defects of the existing technology mentioned above and provide an operating mechanism and rotary switch, which adds an automatic tripping function and simplifies the structure.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0008] case;

[0009] A handle unit, the handle unit including an operating handle and a handle shaft, the operating handle being sleeved on the handle shaft;

[0010] A quick opening and closing unit includes a handle drive disc and a chuck. The handle drive disc is sleeved on the handle shaft, and the chuck is used to connect with the moving contact drive shaft of the switch. A first elastic element is provided between the handle drive disc and the chuck.

[0011] The chuck and the housing have a first engagement state and a second engagement state. The handle drive disk has a first unlocking arm and a second unlocking arm. The handle drive disk has a first unlocking state and a second unlocking state. When the handle drive disk is in the first unlocking state, the first unlocking arm disengages the chuck from the housing in the first engagement state, and the first elastic element stores energy to provide a force for the chuck to switch to the second engagement state. When the handle drive disk is in the second unlocking state, the second unlocking arm disengages the chuck from the housing in the second engagement state, and the first elastic element stores energy to provide a force for the chuck to switch to the first engagement state.

[0012] An energy storage unit includes an energy storage drive arm, a movable buckle, and a second elastic element. The energy storage drive arm is sleeved on the handle shaft. A portion of the movable buckle is connected to the housing through the second elastic element. The energy storage drive arm is connected to a portion of the movable buckle. The housing is provided with a first sliding groove. The movable buckle is slidably engaged with the first sliding groove. Both the energy storage drive arm and the second elastic element can drive the movable buckle to move along the sliding groove, and the driving directions of the energy storage drive arm and the second elastic element are opposite. The movable buckle has a fastening hole and a ramp surface.

[0013] The tripping unit includes a locking member, a third elastic member, and a tripping device. The locking member is connected to the housing through the third elastic member. The tripping device can receive external signals and drive the locking member according to the external signals, so that the locking member separates from the latching hole of the moving buckle.

[0014] When the operating mechanism is in the disengaged state, the chuck and the housing are in the first engaging state, the first elastic element is in the natural state, the locking element abuts against the ramp surface of the moving buckle, the second elastic element is in the natural or slightly stretched state, and the third elastic element is in the natural or slightly compressed state.

[0015] When the operating mechanism is in the closed state, the chuck and the housing are in a second engaging state, the first elastic element is in a natural state, the locking element is inserted into the buckle's buckle hole, the second elastic element is in a stretched state, and the third elastic element is in a natural or slightly compressed state.

[0017] In one embodiment, the moving buckle includes a sliding part and a guide part connected to each other. The sliding part is disposed in the first groove, and the guide part is provided with a traction pin. The traction pin is connected to the energy storage drive arm and the second elastic member respectively.

[0018] In one embodiment, the energy storage drive arm is a U-shaped arm, the opening of the energy storage drive arm faces away from the second elastic member, and there are two energy storage drive arms, the openings of the two energy storage drive arms respectively abutting against the two ends of the traction pin.

[0019] In one embodiment, the handle shaft is provided with a first limiting ring, a second limiting ring and a positioning sleeve, one of the energy storage drive arms is disposed between the first limiting ring and the positioning sleeve, and the other energy storage drive arm is disposed between the positioning sleeve and the handle drive disk, and the second limiting ring is located on the side of the handle drive disk away from the energy storage drive arm.

[0020] In one embodiment, the housing is further provided with a second slide groove, the locking member is slidably connected to the second slide groove, the guide of the second slide groove is perpendicular to the guide of the first slide groove, and the third elastic member provides the locking member with a force along the second slide groove close to the moving buckle.

[0021] In one embodiment, the first elastic element is a torsion spring, the chuck has an elastic element receiving groove, the first elastic element is movably sleeved on the inner wall of the elastic element receiving groove, the elastic element receiving groove has a chuck protrusion, the handle drive disk has a drive protrusion, when the chuck and the housing are in a first engagement state and a second engagement state, the chuck protrusion and the drive protrusion are stacked, the two ends of the first elastic element are respectively located on both sides of the chuck protrusion and the drive protrusion, so that one end of the first elastic element can rotate with the drive protrusion, and the other end of the first elastic element can rotate with the chuck protrusion.

[0022] In one embodiment, the chuck is provided with a first locking arm and a second locking arm disposed opposite to each other, and the housing is provided with a first limiting protrusion and a second limiting protrusion. When the chuck and the housing are in a first locking state, the first locking arm and the second locking arm are respectively locked with the two sides of the first limiting protrusion; when the chuck and the housing are in a second locking state, the first locking arm and the second locking arm are respectively locked with the two sides of the second limiting protrusion.

[0023] When the handle drive disc is in the first unlocked state, the first unlocking arm abuts against the first locking arm, allowing the first locking arm to pass over the first limiting protrusion; when the handle drive disc is in the second unlocked state, the second unlocking arm abuts against the second locking arm, allowing the second locking arm to pass over the second limiting protrusion.

[0024] In one embodiment, the housing has a chuck mounting hole, the sidewall of the chuck mounting hole has a first limiting protrusion and a second limiting protrusion, the chuck is disposed in the chuck mounting hole, and the first locking arm and the second locking arm are arranged around the circumference of the chuck.

[0025] In one embodiment, the housing includes an upper shell, a lower shell, and a release shell. The upper shell and the lower shell are stacked and connected. The release shell is connected to the side of the lower shell away from the upper shell. The operating handle is located on the side of the upper shell away from the lower shell. The chuck is located in the lower shell. One end of the handle shaft passes through the upper shell and is located in the chuck. The release device is located in the release shell.

[0026] A rotary switch includes an on / off structure and an operating mechanism, wherein the chuck of the operating mechanism is connected to the moving contact drive shaft of the on / off structure.

[0027] Compared with the prior art, the present invention has the following advantages:

[0028] 1. The aforementioned operating mechanism, with its handle unit cooperating with the quick-closing / opening unit, energy storage unit, and tripping unit, jointly completes the closing, opening, and automatic tripping functions of the operating mechanism. When the operating mechanism is in the tripped state, rotating the operating handle in the first direction switches the operating mechanism to the closing state. During rotation, the handle shaft drives the energy storage drive arm to rotate. Due to the contact between the locking element and the inclined surface of the moving latch, the energy storage drive arm can move the moving latch along the first slide groove. The moving latch drives the second elastic element to store energy until the locking element is inserted into the latching hole of the moving latch, completing the locking and energy storage of the energy storage unit. Simultaneously, the handle shaft also drives the handle drive disc to rotate, which in turn drives the first unlocking arm and the second unlocking arm to rotate, causing the quick-closing / opening unit to switch from the first latching state to the first unlocking state, and then from the first unlocking state to the second latching state, realizing the rotation of the chuck. Therefore, the chuck can drive the moving contact drive shaft of the switch to rotate, realizing the closing of the switch. When the operating mechanism is in the closing state, rotating the operating handle in the opposite direction to the first direction switches the operating mechanism to the re-latching state. In the open state, during rotation, the handle shaft drives the energy storage drive arm to rotate in the opposite direction. Because the locking element is inserted into the latching hole of the moving latch, the moving latch remains stationary, and the energy storage drive arm separates from the moving latch. Simultaneously, the handle shaft drives the handle drive disc to rotate in the opposite direction, and the quick-closing / opening unit switches from the second latching state to the second unlocking state, and then from the second unlocking state back to the first latching state, achieving the reverse rotation of the chuck. Therefore, the chuck can drive the moving contact drive shaft of the switch to rotate in the opposite direction, achieving the opening of the switch. When the operating mechanism is in the closed state or the re-clamping / opening state, it can also be switched to the tripping state via the trip unit. The locking element separates from the latching hole of the moving latch, and then the second elastic element moves the moving latch along the first slide groove. If the operating mechanism is in the closed state, the moving latch will also move with the energy storage drive arm, thereby driving the handle shaft to rotate in the opposite direction. The handle shaft drives the handle drive disc to rotate in the opposite direction, and then the chuck rotates in the opposite direction, achieving the opening of the switch. Therefore, this operating mechanism not only achieves closing and opening functions through a simple structure, but also has reliable remote opening capability, and the transmission is fast and stable.

[0029] 2. Because the energy storage drive arm is a U-shaped arm, it can only provide the force to stretch the second elastic element of the moving latch. Therefore, when the operating mechanism switches from the closed state to the re-clamping open state, the energy storage drive arm will not interfere with the reverse rotation of the handle shaft. When the operating mechanism automatically trips and opens the circuit, the moving latch can push the handle shaft to rotate in the reverse direction through the energy storage drive arm, thereby realizing the chuck rotation and opening. Furthermore, the two energy storage drive arms make the transmission between the moving latch and the energy storage drive arm more stable and reliable.

[0030] 3. The handle shaft uses a first limiting ring, a second limiting ring, and a positioning sleeve to limit and fix the two energy storage drive arms and the handle drive disc, preventing the energy storage drive arms and the handle drive disc from moving along the axial direction of the handle shaft and improving the stability of the transmission.

[0031] 4. The handle drive disc and the chuck are connected to torsion springs via drive protrusions and chuck protrusions, respectively. Therefore, when the chuck and the housing are in the first and second engaged states, the chuck protrusion and drive protrusion are stacked, and the first elastic element is in its natural state. When the handle drive disc switches from the first engaged state to the first unlocked state, the drive protrusion rotates relative to the chuck protrusion, thereby causing one end of the torsion spring to rotate and store energy. Then, the torsion spring releases the stored energy and causes the chuck to rotate to the second engaged state. Similarly, when the handle drive disc switches from the second engaged state to the second unlocked state, the drive protrusion rotates relative to the chuck protrusion, thereby causing one end of the torsion spring to rotate and store energy. Then, the torsion spring releases the stored energy and causes the chuck to rotate to the first engaged state. Attached Figure Description

[0051] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. This embodiment is based on the technical solution of the present invention and provides detailed implementation methods and specific operating procedures; however, the scope of protection of the present invention is not limited to the following embodiments.

[0052] The following describes in detail, with reference to the accompanying drawings, an operating mechanism 100 and a rotary switch 200 in some embodiments.

[0053] like Figure 2 , Figure 3 , Figure 4 , Figure 12 , Figure 13 , Figure 14a and Figure 14b As shown, in one embodiment, an operating mechanism 100 is provided, including a housing 50, a handle unit 10, a quick-connect and disconnect unit 20, an energy storage unit 30, and a tripping unit 40;

[0054] The handle unit 10 includes an operating handle 11 and a handle shaft 12, with the operating handle 11 sleeved on the handle shaft 12; the quick opening and closing unit 20 includes a handle drive disk 21 and a chuck 22, with the handle drive disk 21 sleeved on the handle shaft 12 and the chuck 22 used to connect with the moving contact drive shaft of the switch, and a first elastic element 23 is provided between the handle drive disk 21 and the chuck 22.

[0055] Furthermore, the chuck 22 and the housing 50 have a first latching state and a second latching state. The handle drive disk 21 has a first unlocking arm 211 and a second unlocking arm 212. The handle drive disk 21 has a first unlocking state and a second unlocking state. When the handle drive disk 21 is in the first unlocking state, the first unlocking arm 211 disengages the chuck 22 from the housing 50 in the first latching state, and the first elastic element 23 stores energy to provide a force for the chuck 22 to switch to the second latching state. When the handle drive disk 21 is in the second unlocking state, the second unlocking arm 212 disengages the chuck 22 from the housing 50 in the second latching state, and the first elastic element 23 stores energy to provide a force for the chuck 22 to switch to the first latching state.

[0056] Meanwhile, the energy storage unit 30 includes an energy storage drive arm 31, a movable buckle 32, and a second elastic member 33. The energy storage drive arm 31 is sleeved on the handle shaft 12. A part of the movable buckle 32 is connected to the housing 50 through the second elastic member 33. The energy storage drive arm 31 is connected to a part of the movable buckle 32. The housing 50 is provided with a first sliding groove 57. The movable buckle 32 is slidably engaged with the first sliding groove 57. Both the energy storage drive arm 31 and the second elastic member 33 can drive the movable buckle 32 to move along the sliding groove. The driving directions of the energy storage drive arm 31 and the second elastic member 33 are opposite. The movable buckle 32 has a latching hole 321 and a ramp surface 322. The release unit 40 includes a locking member 41, a third elastic member 42, and a release device 43. The locking member 41 is connected to the housing 50 through the third elastic member 42. The release device 43 can receive external signals and drive the locking member 41 according to the external signals, so that the locking member 41 is separated from the latching hole 321 of the movable buckle 32.

[0057] When the operating mechanism 100 is in the disengaged state, the chuck 22 and the housing 50 are in the first engaging state, the first elastic element 23 is in the natural state, the locking element 41 abuts against the ramp surface 322 of the movable latch 32, the second elastic element 33 is in the natural state, and the third elastic element 42 is in the natural state (it should be noted that the second elastic element 33 can also be in a slightly stretched state to prevent the parts from sliding; the third elastic element 42 can also be in a slightly compressed state, continuously providing a thrust to the locking element 41, and the housing limiting feature restricts the locking element 41; for ease of description, both the second elastic element 33 and the third elastic element 42 are referred to as such in this embodiment). (Using only the natural state as an example); When the operating mechanism 100 is in the closed state, the chuck 22 and the housing 50 are in the second engagement state, the first elastic member 23 is in the natural state, the locking member 41 is inserted into the latching hole 321 of the moving buckle 32, the second elastic member 33 is in the stretched state, and the third elastic member 42 is in the natural state; When the operating mechanism 100 is in the re-clamping and opening state, the chuck 22 and the housing 50 are in the first engagement state, the first elastic member 23 is in the natural state, the locking member 41 is inserted into the latching hole 321 of the moving buckle 32, the second elastic member 33 is in the stretched state, and the third elastic member 42 is in the natural state.

[0058] The aforementioned operating mechanism 100, with its handle unit 10 cooperating with the quick-closing / opening unit 20, energy storage unit 30, and tripping unit 40, jointly performs the closing, opening, and automatic tripping functions of the operating mechanism 100. When the operating mechanism 100 is in the tripped state, rotating the operating handle 11 in the first direction can switch the operating mechanism 100 to the closing state. During rotation, if... Figure 13 As shown, the handle shaft 12 can drive the energy storage drive arm 31 to rotate. Since the locking member 41 abuts against the inclined surface 322 of the movable buckle 32, the energy storage drive arm 31 can move the movable buckle 32 along the first slide groove 57. The movable buckle 32 drives the second elastic member 33 to store energy until the locking member 41 is inserted into the buckle hole 321 of the movable buckle 32, thus completing the locking and energy storage of the energy storage unit 30; at the same time, as Figure 12 As shown, the handle shaft 12 also rotates the handle drive disc 21, which in turn rotates the first unlocking arm 211 and the second unlocking arm 212, causing the quick-closing unit 20 to switch from the first engaging state to the first unlocking state, and then from the first unlocking state to the second engaging state, thus realizing the rotation of the chuck 22. Therefore, the chuck 22 can rotate the moving contact drive shaft of the switch, realizing the closing of the switch. When the operating mechanism 100 is in the closed state, rotating the operating handle 11 in the opposite direction to the first direction can switch the operating mechanism 100 to the re-deduction opening state. During the rotation, as... Figure 13 As shown, the handle shaft 12 rotates in the opposite direction, causing the energy storage drive arm 31 to rotate. Because the locking member 41 is inserted into the latching hole 321 of the movable latch 32, the movable latch 32 remains stationary, and the energy storage drive arm 31 separates from the movable latch 32; as... Figure 12As shown, simultaneously, the handle shaft 12 drives the handle drive disc 21 to rotate in the opposite direction, and the quick-closing unit 20 switches from the second engaging state to the second unlocking state, and then from the second unlocking state to the first engaging state, realizing the reverse rotation of the chuck 22. Therefore, the chuck 22 can drive the moving contact drive shaft of the switch to rotate in the opposite direction, realizing the opening of the switch; when the operating mechanism 100 is in the closing state or the re-clamping opening state, the trip unit 43 can also switch the operating mechanism 100 to the tripping state (e.g., Figure 14a (As shown); the locking member 41 separates from the latching hole 321 of the movable latch 32, and then the second elastic member 33 moves the movable latch 32 along the first slide groove 57. If the operating mechanism 100 is in the closed state, the movable latch 32 will also move the energy storage drive arm 31, which will drive the handle shaft 12 to rotate in the opposite direction. The handle shaft 12 drives the handle drive disk 21 to rotate in the opposite direction, and then the chuck 22 rotates in the opposite direction, realizing the opening of the switch. Therefore, the operating mechanism 100 not only realizes the closing and opening functions through a simple structure, but also has a reliable remote opening capability and fast and stable transmission.

[0059] Specifically, such as Figure 1 and Figure 3 As shown, in one embodiment, the housing 50 includes an upper housing 51, a lower housing 52, and a release housing 53. The upper housing 51 and the lower housing 52 are stacked and connected. The release housing 53 is connected to the side of the lower housing 52 away from the upper housing 51. The operating handle 11 is located on the side of the upper housing 51 away from the lower housing 52. The chuck 22 is located in the lower housing 52. One end of the handle shaft 12 passes through the upper housing 51 and is located in the chuck 22. The release device 43 is located in the release housing 53.

[0060] In this specific embodiment, the upper shell 51 and the lower shell 52 are connected by multiple screws, which pass through the upper shell 51 and connect to the lower shell 52. The lower shell 52 has a mounting part on the side away from the lower shell 52, and the screw passes through the mounting part to connect to the release shell 53, which facilitates the installation and disassembly of the upper shell 51, the lower shell 52 and the release shell 53.

[0061] Meanwhile, the switching structure 60 is also located on the side of the upper shell 51 away from the lower shell 52, and is arranged in parallel with the release shell 53.

[0062] Specifically, such as Figure 2 and Figure 11 As shown, in one embodiment, the movable buckle 32 includes a sliding part 323 and a guide part 324 connected to each other. The sliding part 323 is disposed in the first sliding groove 57, and the guide part 324 is provided with a traction pin 325. The traction pin 325 is connected to the energy storage drive arm 31 and the second elastic member 33 respectively.

[0063] Furthermore, in one embodiment, the guide portion 324 is provided with a guide groove, and the sliding portion 323 is provided with a guide protrusion. The guide protrusion is inserted into the guide groove in a direction perpendicular to the first slide groove 57, thereby realizing the detachable connection between the sliding portion 323 and the guide portion 324, and ensuring that the guide portion 324 can move along the first slide groove 57 with the sliding portion 323.

[0064] In this specific embodiment, the guide portion 324 is a U-shaped guide portion with the opening of the U-shaped guide portion facing the handle shaft 12. The sliding portion 323 is connected to the bottom wall of the U-shaped guide portion. The traction pin 325 passes through the two side walls of the U-shaped guide portion and extends out of the two side walls of the U-shaped guide portion. The energy storage drive arm 31 is connected to the part of the traction pin 325 that extends out of the U-shaped guide portion. The second elastic member 33 is connected to the part of the traction pin 325 located between the two side walls of the U-shaped guide portion.

[0065] In this specific embodiment, the lower shell 52 is also provided with a fixing pin, and the two ends of the second elastic member 33 are respectively connected to the traction pin 325 and the fixing pin.

[0066] Furthermore, in one embodiment, the sliding part 323 is provided with a latching hole 321 and a ramp surface 322. The sliding part 323 is provided with a ramp surface 322 on one end face guided by the first sliding groove 57. The locking member 41 is also provided with a corresponding inclined surface. The inclined surface on the locking member 41 has the same inclination angle as the ramp surface 322 of the sliding part 323, so that they can fit and abut against each other, avoiding interference of the locking member 41 with the movement of the moving latch 32 when switching from the tripped state to the closed state.

[0067] The locking member 41 is provided with a locking protrusion 411, and an inclined surface is provided on the locking protrusion 411. The locking protrusion 411 can pass through the buckle hole 321 of the movable buckle 32.

[0068] In this specific embodiment, the upper shell 51 and the lower shell 52 are provided with first sliding grooves 57 on their opposite end faces. The upper and lower sides of the sliding part 323 are respectively located in the first sliding grooves 57 of the upper shell 51 and the lower shell 52 to ensure the stability of the sliding of the movable buckle 32.

[0069] Specifically, such as Figure 2 , Figure 5 and Figure 13As shown, in one embodiment, the energy storage drive arm 31 is a U-shaped arm, with its opening facing away from the second elastic member 33. Two energy storage drive arms 31 are provided, and their openings respectively abut against both ends of the traction pin 325. Because the energy storage drive arm 31 is U-shaped, it can only provide the moving latch 32 with the force required to stretch the second elastic member 33. Therefore, when the operating mechanism 100 switches from the closed state to the re-clamping / opening state, the energy storage drive arm 31 will not interfere with the reverse rotation of the handle shaft 12. When the operating mechanism 100 automatically disengages and opens, the moving latch 32 can push the handle shaft 12 to rotate in the opposite direction through the energy storage drive arm 31, thus achieving the rotation and opening of the chuck 22. Furthermore, the two energy storage drive arms 31 make the transmission between the moving latch 32 and the energy storage drive arm 31 more stable and reliable.

[0070] Furthermore, such as Figure 6a and Figure 6b As shown, in one embodiment, the handle shaft 12 is provided with a first limiting ring 121, a second limiting ring 122, and a positioning collar 123. One energy storage drive arm 31 is disposed between the first limiting ring 121 and the positioning collar 123, and another energy storage drive arm 31 is disposed between the positioning collar 123 and the handle drive disk 21. The second limiting ring 122 is located on the side of the handle drive disk 21 away from the energy storage drive arm 31. The handle shaft 12, through the first limiting ring 121, the second limiting ring 122, and the positioning collar 123, achieves the limiting and fixing of the two energy storage drive arms 31 and the handle drive disk 21, preventing the energy storage drive arms 31 and the handle drive disk 21 from moving along the axial direction of the handle shaft 12 and improving the stability of the transmission.

[0071] In this specific embodiment, the handle shaft 12 is also provided with a flat key 124, which is disposed between the first limiting ring 121 and the second limiting ring 122. The positioning sleeve 123, the energy storage drive arm 31 and the handle drive disk 21 are all provided with mounting grooves. The flat key 124 is inserted into the mounting groove to realize the coaxial rotation of the handle shaft 12 with the positioning sleeve 123, the energy storage drive arm 31 and the handle drive disk 21.

[0072] Specifically, such as Figure 5 and Figure 7 As shown, in one embodiment, the housing 50 is further provided with a second slide groove 58, and the locking member 41 is slidably connected to the second slide groove 58. The guide of the second slide groove 58 is perpendicular to the guide of the first slide groove 57, and the third elastic member 42 provides a force to the locking member 41 along the second slide groove 58 towards the movable latch 32. The second slide groove 58 is used to limit the release and locking direction of the locking member 41, ensuring the reliability of the release and locking of the locking member 41.

[0073] Furthermore, in one embodiment, the upper shell 51 and the lower shell 52 are provided with a second sliding groove 58 on their opposite end faces, and the upper and lower sides of the locking member 41 are respectively located in the second sliding groove 58.

[0074] Among them, such as Figure 10 As shown, the lower shell 52 is provided with a limiting block, and the locking member 41 is provided with a locking elastic groove 412. The locking elastic groove 412 is used to accommodate the third elastic member 42. The two ends of the third elastic member 42 are respectively connected to the limiting block and the bottom wall of the locking elastic groove 412.

[0075] like Figure 7 and Figure 10 As shown, in this specific embodiment, the locking member 41 is also provided with a release arm 413, and the bottom of the second slide groove 58 is provided with a clearance hole, through which the release arm 413 passes and connects to the release device 43.

[0076] Furthermore, the trip unit 43 is equipped with an ejector rod 431, which is pushed by an electromagnet and abuts against the trip arm 413 to drive the locking member 41 away from the moving trip 32. At the same time, the trip housing 53 is equipped with a reset hole communicating with the outside for installing a manual reset button 44. The manual reset button 44 is positioned opposite to the ejector rod 431. When the ejector rod 431 is pushed out, the manual reset button 44 can be pressed to return the ejector rod 431 to its initial state.

[0077] Specifically, such as Figure 4 , Figure 7 , Figure 8a , Figure 8b , Figure 9a and Figure 9b As shown, in one embodiment, the first elastic element 23 is a torsion spring. The chuck 22 is provided with an elastic element receiving groove 221. The first elastic element 23 is movably sleeved on the inner wall of the elastic element receiving groove 221. The elastic element receiving groove 221 is provided with a chuck protrusion 222. The handle drive disk 21 is provided with a drive protrusion 213. When the chuck 22 and the housing 50 are in a first snap-fit ​​state and a second snap-fit ​​state, the chuck protrusion 222 and the drive protrusion 213 are stacked. The two ends of the first elastic element 23 are located on both sides of the chuck protrusion 222 and the drive protrusion 213, respectively, so that one end of the first elastic element 23 can rotate with the drive protrusion 213, and the other end of the first elastic element 23 can rotate with the chuck protrusion 222.

[0078] like Figure 12As shown, the handle drive disc 21 and the chuck 22 are connected to torsion springs via drive protrusion 213 and chuck protrusion 222, respectively. Therefore, when the chuck 22 and the housing 50 are in the first and second engagement states, the chuck protrusion 222 and drive protrusion 213 are stacked, and the first elastic element 23 is in its natural state. When the handle drive disc 21 switches from the first engagement state to the first unlock state, the drive protrusion 213 rotates relative to the chuck protrusion 222, thereby causing one end of the torsion spring to rotate and store energy. Then, the torsion spring releases the stored energy and causes the chuck 22 to rotate to the second engagement state. Similarly, when the handle drive disc 21 switches from the second engagement state to the second unlock state, the drive protrusion 213 rotates relative to the chuck protrusion 222, thereby causing one end of the torsion spring to rotate and store energy. Then, the torsion spring releases the stored energy and causes the chuck 22 to rotate to the first engagement state.

[0079] Furthermore, such as Figure 8a , Figure 8b , Figure 9a ,and Figure 9b In one embodiment, the chuck 22 is provided with a first locking arm 223 and a second locking arm 224 disposed opposite to each other, and the housing 50 is provided with a first limiting protrusion 55 and a second limiting protrusion 56. When the chuck 22 and the housing 50 are in a first locking state, the first locking arm 223 and the second locking arm 224 are respectively locked with the two sides of the first limiting protrusion 55; when the chuck 22 and the housing 50 are in a second locking state, the first locking arm 223 and the second locking arm 224 are respectively locked with the two sides of the second limiting protrusion 56.

[0080] When the handle drive disc 21 is in the first unlocked state, the first unlocking arm 211 abuts against the first locking arm 223, allowing the first locking arm 223 to pass over the first limiting protrusion 55; when the handle drive disc 21 is in the second unlocked state, the second unlocking arm 212 abuts against the second locking arm 224, allowing the second locking arm 224 to pass over the second limiting protrusion 56.

[0081] Furthermore, in one embodiment, the housing 50 is provided with a chuck mounting hole 54, the side wall of the chuck mounting hole 54 is provided with a first limiting protrusion 55 and a second limiting protrusion 56, the chuck 22 is disposed in the chuck mounting hole 54, and the first locking arm 223 and the second locking arm 224 are arranged around the circumference of the chuck 22.

[0082] There is a certain gap between the first locking arm 223 and the second locking arm 224 and the body of the chuck 22. Therefore, the first locking arm 223 and the second locking arm 224 have a certain deformation space in the radial direction of the chuck 22. When the first unlocking arm 211 abuts against the first locking arm 223, the first locking arm 223 deforms and passes the first limiting protrusion 55. When the second unlocking arm 212 abuts against the second locking arm 224, the second locking arm 224 deforms and passes the second limiting protrusion 56.

[0083] Meanwhile, both the first locking arm 223 and the second locking arm 224 have slopes that gradually approach the sidewall of the chuck mounting hole 54 on the side away from the chuck 22 body. Therefore, after the first locking arm 223 passes the first limiting protrusion 55, the second locking arm 224 passes the second limiting protrusion 56 due to the rebound force of the first elastic element 23 and the slope, and reaches the second locking state. After the second locking arm 224 passes the second limiting protrusion 56, the first locking arm 223 passes the first limiting protrusion 55 due to the rebound force of the first elastic element 23 and the slope, and reaches the first locking state.

[0084] In this specific embodiment, the bottom of the chuck 22 is also provided with a moving contact mounting hole 225 for connecting to the moving contact drive shaft of the switch.

[0085] Furthermore, the chuck mounting hole 54 is located in the lower housing 52.

[0086] like Figure 1 , Figure 2 and Figure 3 As shown, in one embodiment, a rotary switch 200 is provided, including an on / off structure 60 and the aforementioned operating mechanism 100, wherein the chuck 22 of the operating mechanism 100 is connected to the moving contact drive shaft of the on / off structure 60.
