For example, "horizontal" merely means that the direction is more horizontal than "vertical" and does not mean that the structure must be perfectly horizontal, but may be slightly inclined.

In the description of the present invention, it should also be noted that, unless otherwise explicitly specified or limited, the terms "disposed," "mounted," "connected," and "connected" are to be construed broadly and may, for example, be fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Referring to fig. 1 to 5, the present embodiment provides an operating device, which includes a housing 70, and a tripping mechanism 10, an energy storage mechanism 20, a locking mechanism 30 and a resetting mechanism 40 respectively disposed in the housing 70, wherein the locking mechanism 30 can lock the energy storage mechanism 20 in an energy storage state;

the tripping mechanism 10 drives the resetting mechanism 40 and the locking mechanism 30 to rotate reversely according to the received tripping signal, so that the locking mechanism 30 releases the locking of the energy storage mechanism 20; the unlocked energy storage mechanism 20 releases energy to drive the switch body 210 of the rotary switch to open and drive the reset mechanism 40 to rotate in the forward direction so as to reset the tripping mechanism 10.

The tripping mechanism 10 is a magnetic flux tripper, and includes a fixed portion and a movable iron core in transmission connection with the fixed portion, and the movable iron core can be ejected from the fixed portion when receiving a tripping signal. In the present embodiment, the plunger is interlocked with one end of the lock mechanism 30 and one end of the reset mechanism 40, respectively, and can drive the lock mechanism 30 and the reset mechanism 40 to rotate. Further, it should be understood that the magnetic flux release of the present application should further include an external interface, where the external interface is used to electrically connect with a control system of the user side, so that the user side can transmit a release signal to the magnetic flux release when the control system is connected with the external interface.

In the present embodiment, the locking mechanism 30 cooperates with the energy storage mechanism 20 to lock the energy storage mechanism 20 so as to keep the energy storage mechanism 20 in the energy storage state; when the energy storage mechanism 20 is in the energy storage state, at this time, the trip mechanism 10 receives a trip signal, and the movable iron core of the trip mechanism 10 is ejected from the fixed portion, and can drive the locking mechanism 30 to disengage from the energy storage mechanism 20, so that the energy storage mechanism 20 is unlocked to release energy. That is, the locking mechanism 30 can lock the energy storage mechanism 20 in the energy storage state, and can be disengaged from the energy storage mechanism 20 under the driving of the plunger, so that the energy storage mechanism 20 unlocks the energy storage mechanism 20 to release the energy.

The reset mechanism 40 can be driven to move the movable iron core of the tripping mechanism 10 when the energy storage mechanism 20 releases energy, so that the movable iron core retracts to the fixed part to be reset. Specifically, when the tripping mechanism 10 receives a tripping signal, the movable iron core is ejected out to drive the locking mechanism 30 and the reset mechanism 40 to rotate reversely, so that the locking mechanism 30 unlocks the energy storage mechanism 20; when the energy storage mechanism 20 unlocks and releases the stored energy, the energy storage mechanism 20 can drive one end of the reset mechanism 40, which is far away from the movable iron core, to move, so that the reset mechanism 40 rotates in the forward direction to push the movable iron core to retract, and thus, the tripping mechanism 10 can reset.

It should be noted that, the reset of the movable iron core is realized in the process of opening the brake. That is, when the trip mechanism 10 receives a trip signal, the plunger drives the reset mechanism 40 and the locking mechanism 30 to move, and the locking mechanism 30 unlocks the energy storage mechanism 20. Thus, the energy storage mechanism 20 releases the stored energy, so as to drive the switch body 210 of the rotary switch to open. It is easy to understand that the switch body 210 in this application is a switching-on/off action system of a rotary switch, the energy storage mechanism 20 can drive the switch body 210 to switch off when releasing energy, and the energy storage mechanism 20 can drive the switch body 210 to switch on when rotating in the forward direction to store energy.

In summary, the operating device provided by the present application includes a tripping mechanism 10, an energy storage mechanism 20, a locking mechanism 30, and a resetting mechanism 40, wherein the locking mechanism 30 locks the energy storage mechanism 20 in an energy storage state; when the tripping mechanism 10 receives a tripping signal, the tripping mechanism 10 can drive the resetting mechanism 40 and the locking mechanism 30 to rotate in opposite directions, so that the locking mechanism 30 unlocks the energy storage mechanism 20; the unlocked energy storage mechanism 20 can drive the switch body 210 of the rotary switch to open under the action of releasing energy, and drive the reset mechanism 40 to rotate in the forward direction so as to reset the tripping mechanism 10. Thus, when a user uses the device, if the rotary switch needs to be remotely tripped, the user side can send a tripping signal to the tripping mechanism 10, and after the tripping mechanism 10 receives the tripping signal, the tripping mechanism 10 acts to drive the resetting mechanism 40 and the locking mechanism 30 to rotate in the opposite direction, so that the locking mechanism 30 is separated from the energy storage mechanism 20, and the energy storage mechanism 20 is unlocked to release the stored energy. After the energy storage mechanism 20 is unlocked, the energy storage mechanism 20 can rotate in the reverse direction to drive the switch body 210 of the rotary switch to open the switch, and meanwhile, the energy storage mechanism 20 can act on the reset mechanism 40 in the energy release process, so that the reset mechanism 40 rotates in the forward direction, the reset mechanism 40 pushes the tripping mechanism 10 to act in the rotating process, and the tripping mechanism 10 resets. The application provides an operating means, it can realize rotary switch's long-range dropout separating brake, and can need not alone to carry out the operation that resets to rotary switch's separating brake state after rotary switch separating brake finishes, alright with the automatic re-setting that realizes rotary switch at the in-process of separating brake. The operating device is simple and compact in structure, convenient to operate, more suitable for operation requirements of users, and capable of improving user experience.

Referring to fig. 6 and 7, the energy storage mechanism 20 includes a limiting portion 211 and a driving portion 212, and the locking mechanism 30 is capable of locking the energy storage mechanism 20 by cooperating with the limiting portion 211; after the energy storage mechanism 20 is unlocked, the driving portion 212 can act on the reset mechanism 40 to enable the reset mechanism 40 to drive the tripping mechanism 10 to reset.

That is, in the initial state (i.e., when the energy storage mechanism 20 is in the energy storage state), the locking mechanism 30 is engaged with the stopper portion 211 of the energy storage mechanism 20, and the locking mechanism 30 locks the energy storage mechanism 20; when the tripping mechanism 10 receives a tripping signal sent by a user terminal, the tripping mechanism 10 acts to drive the locking mechanism 30 and the reset mechanism 40 to rotate in opposite directions, and at this time, the locking mechanism 30 is disengaged from the limiting part 211, so that the energy storage mechanism 20 is unlocked to store energy and release the energy; when the energy storage mechanism 20 releases the stored energy, the energy storage mechanism 20 can drive the switch body 210 to open the switch, and can drive the reset mechanism 40 to rotate in the forward direction through the driving portion 212, so that the reset mechanism 40 acts on the trip mechanism 10, and the trip mechanism 10 is reset.

It should be noted that the limiting portion 211 may be a matching surface provided on the energy storage mechanism 20 body, or a matching block connected to the energy storage mechanism 20, and the structural form of the limiting portion 211 is not limited in this application, as long as the limiting portion 211 can be matched with the locking mechanism 30 to lock the energy storage mechanism 20 when the energy storage mechanism 20 is in the energy storage state.

The driving portion 212 may be a protrusion protruding from the body of the energy storage mechanism 20, and will not contact with the reset mechanism 40 when the energy storage mechanism 20 stores energy; when the stored energy is released, the reset mechanism 40 can be acted on to drive the reset mechanism 40 to rotate. The structure form of the bump is not limited in the present application, and for example, the bump may be a triangular bump (as shown in fig. 3 to 5) or a quadrangular bump; for another example, the energy storage mechanism 20 may have a profile knot structure protruding from the body thereof.

The stopper 211 and the driving part 212 may be integrally formed with the energy storage mechanism 20, or may be separate components from the energy storage mechanism 20, which is not limited in this application.

Referring to fig. 6 and 7, optionally, the energy storage mechanism 20 further includes a shaft sleeve 21 and an energy storage spring 22, the limiting portion 211 and the driving portion 212 are respectively disposed on the shaft sleeve 21, one end of the energy storage spring 22 is connected to the shaft sleeve 21, and the other end is fixed to the housing 70 of the rotary switch; the positive rotation of the drive sleeve 21 causes the charging spring 22 to charge energy.

In this embodiment, the shaft sleeve 21 has a structure as shown in fig. 7, the shaft sleeve 21 is provided with a first mounting hole 214, the bottom of the shaft sleeve 21 is provided with an action block 215, and the shaft sleeve 21 is provided with a mounting cavity 213. Wherein, wear to locate in first mounting hole 214 through the drive mechanism 50 with rotary switch to drive mechanism 50 and effect piece 215 cooperation, can drive axle sleeve 21 and rotate. One end of the energy storage spring 22 is fixed in the mounting cavity 213 of the bushing 21, and the other end is connected to the housing 70 of the rotary switch (in the present embodiment, specifically, the other end of the energy storage spring 22 is connected to the case 71 of the rotary switch). The energy storage spring 22 can be stored by the positive rotation of the sleeve 21.

It should be noted that the aforementioned limiting portion 211 and the driving portion 212 may be disposed on the shaft sleeve 21, as shown in fig. 7, the driving portion 212 may be protruded on the outer peripheral wall of the shaft sleeve 21, and the limiting portion 211 may be a mating surface on the shaft sleeve 21.

In the present embodiment, when the energy storing mechanism 20 does not store energy (and at the same time, when the switch body 210 of the rotary switch is in the open state, as shown in fig. 4), the locking mechanism 30 abuts against the outer peripheral wall of the bushing 21, the bushing 21 is not limited, and the bushing 21 can normally rotate; when the driving shaft sleeve 21 rotates forward to drive the energy storage spring 22 to store energy, the limiting portion 211 on the shaft sleeve 21 rotates and rotates to be matched with the locking mechanism 30, so that the energy storage mechanism 20 is locked by the locking mechanism 30, and at this time, the energy storage mechanism 20 is locked in an energy storage state, as shown in fig. 5.

Referring to fig. 1, fig. 6 and fig. 8, optionally, the locking mechanism 30 includes a first body 31 and a matching portion 311 disposed on the first body 31, and one end of the first body 31 away from the trip mechanism 10 is rotatably connected to the housing 70 of the rotary switch; the engaging portion 311 is disposed on a side of the first body 31 close to the energy storage mechanism 20, and is configured to engage with the energy storage mechanism 20 to lock the energy storage mechanism 20.

As shown in fig. 8, in the present embodiment, the locking mechanism 30 includes a first body 31, and the engaging portion 311 is protruded on the first body 31. One end of the first body 31, which is far away from the trip mechanism 10, is rotatably connected to the housing 70 of the rotary switch, and the other end of the first body 31 is used for cooperating with the trip mechanism 10.

Optionally, as shown in fig. 3 to 5, the locking mechanism 30 further includes a locking spring 32, one end of the locking spring 32 is connected to the first body 31, and the other end is fixed on the housing 70; the reverse rotation of the trip mechanism 10 driving the locking mechanism 30 can cause the locking spring 32 to store energy.

In the present embodiment, when the lock mechanism 30 abuts against the outer peripheral wall of the energy storing mechanism 20 (specifically, the outer peripheral wall of the boss 21), the lock spring 32 is in the compressed energy storing state; when the locking mechanism 30 locks the energy storage mechanism 20, the locking spring 32 is in a compressed energy storage state; the locking spring 32 is also in a compressed energy storage state when the locking mechanism 30 is driven to rotate in the reverse direction by the trip mechanism 10. In the present embodiment, when the lock mechanism 30 moves (i.e., moves in the forward direction) from the abutment with the outer peripheral wall of the boss 21 in the direction to lock the boss in cooperation with the boss 21, the stored energy of the lock spring 32 gradually decreases.

Referring to fig. 3 and 9, the reset mechanism 40 is selectively rotatably connected to the housing 70 of the rotary switch, and has one end contacting the trip mechanism 10 and the other end capable of being driven to rotate when the energy storage mechanism 20 releases energy.

It will be appreciated that the opposite ends of the reset mechanism 40 are located on opposite sides of its center of rotation. Wherein one end of the reset mechanism 40 is contacted with the tripping mechanism 10, and the other end is driven to rotate when the energy storage mechanism 20 releases energy. Driven rotation here represents that when the stored energy of the energy storage mechanism 20 is released, the end of the energy storage mechanism 20 away from the tripping mechanism 10 can be driven by the energy storage mechanism 20, so that the energy storage mechanism 20 drives the whole reset mechanism 40 to rotate in the forward direction.

The operating device further includes a return spring 41 having one end connected to the return mechanism 40 and the other end connected to the housing 70, see fig. 3 to 5; the tripping mechanism 10 drives the reset mechanism 40 to rotate reversely, so that the reset spring 41 can be charged with energy.

That is, when the tripping mechanism 10 is not tripped, one end of the resetting mechanism 40 close to the tripping mechanism 10 contacts with the tripping mechanism 10, and the resetting spring 41 is in an energy storage state; when the tripping mechanism 10 is tripped, the movable iron core of the tripping mechanism 10 overcomes the elastic force of the reset spring 41 to pop up and drive the reset mechanism 40 to rotate reversely, and at this time, the reset spring 41 is stressed to store energy; when the stored energy of the energy storing mechanism 20 is released, at this time, the energy storing mechanism 20 can rotate reversely and drive the reset mechanism 40 to rotate forwardly in cooperation with the energy releasing action of the reset spring 41, so as to reset the tripping mechanism 10, and therefore, the reset mechanism 40 always has an abutting tendency with the tripping mechanism 10 through the reset spring 41.

Referring to fig. 9, the reset mechanism 40 includes a reset body 42 and a bending portion 43 bent from the reset body 42 toward the energy storage mechanism 20, and the bending portion 43 and the reset body 42 together form a position-avoiding cavity 44; when the energy storage mechanism 20 rotates reversely, the energy storage mechanism can pass through the avoiding cavity 44 and act on the bending part 43, so that the reset body 42 drives the tripping mechanism 10 to reset.

For easy understanding, referring to fig. 16 to 18, when the energy storage mechanism 20 is in the energy storage state, the driving portion 212 on the shaft sleeve 21 is in the position shown in fig. 16; when the tripping mechanism 10 receives a tripping signal and drives the tripping mechanism 10 to pop up, the locking mechanism 30 unlocks the energy storage mechanism 20, the driving part 212 rotates to the position as shown in fig. 17, and at this time, the avoiding cavity 44 gives way to the driving part 212; the driving part 212 continues to rotate reversely under the energy releasing action of the energy storing mechanism 20, at this time, the driving part 212 will pass through the avoiding cavity 44 to move to abut against the bending part 43, as shown in fig. 18; at this time, the driving portion 212 further rotates to drive the bending portion 43 to rotate in the forward direction, so as to drive the trip mechanism 10 to reset.

As shown in fig. 12, the cam plate 60 is provided with an accommodation groove 611, and the accommodation groove 611 is used for accommodating the engaging and disengaging spring 62. The two ends of the opening and closing spring 62 are respectively located at two opposite sides of the limiting block 63 at the bottom of the accommodating groove 611.

The toggle portion 523 is disposed on the combining plate 52, and the toggle portion 523 may extend from an end of the plate body 521 of the combining plate 52 away from the rotating shaft 51. An end of the toggle portion 523 away from the disc body 521 may extend into the accommodating groove 611. The switching plate 52 is driven to rotate, and the toggle part 523 can toggle one end of the switching spring 62, so that the switching spring 62 stores energy.

The cam plate 60 is in transmission connection with the switch body 210 and is used for driving the switch body 210 to open or close, and specifically, the specific connection mode of the cam plate 60 and the switch body 210 is not limited in the present application, and a person skilled in the art can select an appropriate mode by himself or herself.

For example, referring to fig. 12 and 13, the cam plate 60 includes a second body 61, and a first elastic block 64 and a second elastic block 65 respectively provided on the second body 61; the separation and combination disk 52 includes a first acting portion 524 and a second acting portion 525; the operating device further comprises a housing 70, the housing 70 comprises a casing 71, a first clamping block 711 and a second clamping block 712 are arranged on the casing 71, and the second clamping block 712 can be clamped between the first elastic block 64 and the second elastic block 65 for locking the cam plate 60 to rotate in the radial direction.

The energy storage mechanism 20 drives the rotating shaft 51 to rotate reversely under the action of energy release, the rotating shaft 51 can drive the switching spring 62 to store energy through the toggle part 523 of the switching disc 52, and the second acting part 525 acts on the second elastic block 65 to unlock the cam disc 60; the cam plate 60 after unlocking can rotate reversely under the action of the energy release of the opening and closing spring 62 to drive the switch body 210 to open the brake, and after opening the brake, the first clamping block 711 is clamped between the first elastic block 64 and the second elastic block 65 to lock the cam plate 60.

The cover 71 is fastened to a base 72 of the rotary switch, and can be engaged with the base 72 to house the energy storing mechanism 20, the lock mechanism 30, the return mechanism 40, and the switching plate 52 of the transmission mechanism 50, as shown in fig. 1 and 2.

Referring to fig. 12, the first elastic block 64 and the second elastic block 65 are protruded on the second body 61. The first elastic block 64 and the second elastic block 65 are arranged at intervals, and a first clamping block 711 or a second clamping block 712 can be clamped in a gap between the first elastic block 64 and the second elastic block 65.

It should be understood that the clutch spring 62 is disposed in the containing groove 611 of the cam plate 60, and two ends of the clutch spring 62 are respectively abutted against two opposite sides of the limiting block 63 in the cam plate 60, so that when one end of the clutch spring 62 is rotated by the shifting portion 523, the cam plate 60 has a rotation tendency in the same direction as the clutch plate 52.

Illustratively, when the second detent block 712 is clamped between the first elastic block 64 and the second elastic block 65, the cam plate 60 is locked by the second detent block 712 and cannot rotate; at this time, the energy storage mechanism 20 drives the rotating shaft 51 to rotate reversely under the action of energy release, the rotating shaft 51 can drive the switching spring 62 to store energy through the toggle part 523 of the switching disc 52, and the second acting part 525 acts on the second elastic block 65 to unlock the cam disc 60 (namely, by rotating the switching disc 52, the second acting part 525 on the switching disc 52 presses the second elastic element on the cam disc 60 downwards, and when the second elastic element is pressed downwards, the housing 71 releases the locking of the cam disc 60); the unlocked cam plate 60 can rotate in the reverse direction under the driving of the opening and closing spring 62 to drive the switch body 210 to open the switch, and after the switch is opened, the first clamping block 711 is clamped between the first elastic block 64 and the second elastic block 65 to lock the cam plate 60.

Similarly, when the rotary switch is in the opening state, the rotating shaft 51 is driven to rotate in the forward direction, the toggle part 523 drives the switch-on/off spring 62 to store energy, and the first acting part 524 acts on the first elastic member to unlock the cam plate 60 (the first elastic member is pressed down by the first acting part 524 to unlock the cam plate 60); the unlocked cam plate 60 can drive the switch body 210 to be closed by the opening and closing spring 62, and after closing, the second locking piece 712 can be engaged between the first elastic piece 64 and the second elastic piece 65 to lock the cam plate 60, as shown in fig. 14.

In order to facilitate the operation of the transmission mechanism 50 by the user, in the present embodiment, the operating device further includes a handle 53, and the handle 53 is disposed at an end of the rotating shaft 51 far from the combining and separating disc 52 and is used for driving the rotating shaft 51 to rotate.

Optionally, referring to fig. 1, fig. 2 and fig. 15, the operating device further includes a housing 70, the housing 70 includes a base 72, the energy storage mechanism 20 is drivingly connected to the base 72, and the locking mechanism 30 and the restoring mechanism 40 are rotatably connected to the base 72.

One end of the lock spring 32 is connected to the lock mechanism 30, and the other end is connected to the base 72 of the housing 70. One end of the return spring 41 may be connected to the return mechanism 40, and the other end may be connected to the base 72.

In addition, the housing 70 provided by the present application may further include an external casing 73, as shown in fig. 1 and fig. 2, the external casing 73 is used for accommodating the trip mechanism 10, so as to avoid potential safety hazards caused by external leakage of the trip mechanism 10.

The operation principle of the operation device provided in the present application will be explained below.

When in the opening state: the sleeve 21 is in its maximum angular position of counter-rotation (corresponding to a counter-clockwise rotation in the present application); the transmission mechanism 50 is also in the maximum angular position of counterclockwise rotation; the first locking block 711 on the housing 71 is locked between the first elastic block 64 and the second elastic block 65 to lock the cam plate 60; the matching part 311 of the locking mechanism 30 is in contact with the outer peripheral wall of the shaft sleeve 21 (the locking spring 32 is in an energy storage state), and the locking mechanism 30 is not in contact with the movable iron core of the tripping mechanism 10; one end of the reset mechanism 40 close to the trip mechanism 10 is in contact with the plunger of the trip mechanism 10, and the driving portion 212 of the shaft sleeve 21 is in contact with the reset mechanism 40, as shown in fig. 4.

When normal switching-on operation is carried out: in addition to fig. 4, the handle 53 is rotated in the forward direction, and both the rotating shaft 51 and the switching disk 52 can be rotated in the forward direction. At this time, the switching disc 52 rotates in the forward direction, and one end of the switching spring 62 is driven to move by the toggle portion 523, so that the switching spring 62 is subjected to compression energy storage (the cam disc 60 tends to rotate in the forward direction due to the compression energy storage of the switching spring 62), but the cam disc 60 is in a locked state because the first clamping block 711 is clamped between the first elastic block 64 and the second elastic block 65 of the cam disc 60. At this time, when the rotation shaft 51 continues to rotate, the first acting portion 524 of the clutch plate 52 acts on the first elastic member to deform the first elastic member to unlock the cam plate 60; the cam plate 60 after unlocking can rotate in the forward direction by the opening and closing spring 62, and the switch body 210 is driven to be closed. After the cam plate 60 is closed to a certain position, the second positioning block 712 is engaged between the first elastic block 64 and the second elastic block 65 to lock the cam plate 60, as shown in fig. 15.

At this time, the handle 53 continues to be rotated in the forward direction, the shaft sleeve 21 is rotated in the forward direction under the driving of the switching disc 52, and at the same time, the energy storage spring is compressed, the engaging portion 311 of the locking mechanism 30 is separated from the peripheral wall of the shaft sleeve 21, the locking spring 32 releases energy to drive the locking mechanism 30 to reset, the engaging portion 311 of the locking mechanism 30 is engaged with the limiting portion 211 of the shaft sleeve 21, at this time, the driving force on the handle 53 is released, the shaft sleeve 21 is locked by the locking mechanism 30, the energy storage spring 22 is in an energy storage state, and one end of the locking mechanism 30 close to the tripping mechanism 10 moves to be in contact with the movable iron core of the tripping mechanism 10, as shown in fig. 5.

When carrying out long-range separating brake: in the state shown in fig. 5 (at this time, the switch body 210 is already closed), the trip mechanism 10 receives a trip signal sent by the user, and the plunger of the trip mechanism 10 pops out, as shown in fig. 16. The movable iron core overcomes the elastic force of the locking spring 32 and the reset spring 41 and drives the locking mechanism 30 and the reset mechanism 40 to rotate reversely, the matching part 311 of the locking mechanism 30 is separated from the limiting part 211 of the shaft sleeve 21, at the moment, the locking mechanism 30 releases the locking of the shaft sleeve 21, the shaft sleeve 21 rotates reversely under the action of the energy releasing of the energy storing spring 22, so that the clutch disc 52 is driven to rotate reversely, the reverse rotation of the clutch disc 52 can drive the shifting part 523 to shift one end of the clutch spring 62 to rotate reversely for energy storing, and at the moment, the cam disc 60 generates a reverse rotation trend. When the switching disc 52 continues to rotate reversely, the second acting part 525 on the switching disc 52 will act on the second elastic block 65 to unlock the cam disc 60 (i.e. by rotating the switching disc 52, the second acting part 525 on the switching disc 52 will press down the second elastic member on the cam disc 60, and when the second elastic member is pressed down, the housing 71 will release the lock on the cam disc 60); the unlocked cam disc 60 can rotate reversely under the drive of the opening and closing spring 62 to drive the switch body 210 to open.

The energy storage spring 22 continues to drive the shaft sleeve 21 to rotate counterclockwise under the action of energy storage release, and the driving portion 212 of the shaft sleeve 21 contacts with one end of the reset mechanism 40 away from the trip mechanism 10, as shown in fig. 17. At this time, the sleeve 21 continues to rotate in the reverse direction under the action of the energy storage spring 22, and the driving portion 212 of the sleeve 21 pushes the restoring mechanism 40 to rotate in the forward direction around the rotation center. In the process of forward rotation of the reset mechanism 40, the reset mechanism 40 gradually pushes the movable iron core of the trip mechanism 10 to retract, the shaft sleeve 21 rotates reversely to a proper position, the reset mechanism 40 drives the movable iron core to retract to a proper position, and the trip mechanism 10 resets, as shown in fig. 18.

When the operating device is in a buckle carrying state, the operating principle of driving the operating device to switch off or switch on is as follows:

it should be noted that the buckle state means: at this time, as shown in fig. 5, the engaging portion 311 of the lock mechanism 30 engages with the stopper portion 211 of the boss 21 to lock the boss 21, and the charging spring 22 is in a charging state.

After closing (under the state of carrying and buckling) during manual opening: at this time, the operating device is in a closing and fastening state. The handle 53 is manually rotated in the reverse direction, and the handle 53 drives the rotating shaft 51 to rotate in the reverse direction. Because the arc-shaped groove 522 on the split-combination disk 52 and the action block 215 on the shaft sleeve 21 are in clearance fit linkage, the reverse rotation of the split-combination disk 52 cannot drive the shaft sleeve 21 to rotate simultaneously (i.e., the split-combination disk 52 will firstly perform a section of idle stroke, and the rotation of the shaft sleeve 21 has a delay relative to the split-combination disk 52), therefore, the shaft sleeve 21 is still locked by the locking mechanism 30, and the energy storage spring 22 is still in an energy storage state. The rotating shaft 51 rotates reversely, and the switching spring 62 is switched by the toggle part 523 on the switching disc 52 to rotate and store energy, so that the cam disc 60 tends to rotate reversely; as the opening and closing disc 52 continues to rotate, the second acting portion 525 on the opening and closing disc 52 will contact the second elastic block 65 of the cam disc 60 and press the second elastic block 65 to deform it, at which time the second elastic block 65 on the cam disc 60 is compressed to be out of contact with the second catching block 712 on the housing 71, and the cam disc 60 is unlocked and rotates reversely. At this point, reverse rotation of the cam plate 60 will cause the contact system to perform a tripping operation.

When manual closing is carried out after opening (carrying and buckling state): at this time, the handle 53 is rotated in the forward direction manually, so that the rotating shaft 51 is driven to rotate in the forward direction; because the arc-shaped groove 522 on the split-combination disk 52 is in clearance fit linkage with the action block 215 on the shaft sleeve 21, the shaft sleeve 21 cannot be driven to rotate by the rotation of the split-combination disk 52 at this time, the shaft sleeve 21 is still in a state locked by the locking mechanism 30, and the energy storage spring 22 is in an energy storage state. Continuing to rotate the rotating shaft 51 in the positive direction, the clutch disc 52 drives the clutch spring 62 through the toggle part 523 to compress and store energy, so that the cam disc 60 tends to rotate in the positive direction; as the first acting portion 524 of the combining plate 52 is engaged with the first elastic block 64 of the cam plate 60 and presses the first elastic block 64 to deform it, the first elastic member of the cam plate 60 will be compressed to be out of contact with the first catching block 711 of the housing 71, the cam plate 60 is unlocked to rotate in the forward direction, and the switch body 210 can be moved by the cam plate 60 to perform a switching operation.

Referring to fig. 1 and fig. 2, the present application further provides a rotary switch, which includes a switch body 210 and the above-mentioned operating device, wherein the switch body 210 is in transmission connection with the operating device, and is used for driving the switch body 210 to open or close.
