Referring to fig. 1 to 3, an embodiment of the present application provides an operating mechanism 100, which includes a housing, a trip assembly 120 disposed in the housing, and a switching-on/off assembly, wherein the switching-on/off assembly includes a reset lever 131, and the reset lever 131 is rotatably connected with the housing and is linked with the trip assembly 120; when the operating mechanism 100 is switched on, the switching-on/off assembly rotates along a first direction, and the switching-on/off assembly stores energy and drives the reset lever 131 to move towards the trip assembly 120 so as to drive the iron core 121 of the trip assembly 120 to reset; after the operating mechanism 100 is switched on, the switching-on/off assembly releases energy and rotates along a second direction, so that the reset lever 131 is separated from the iron core 121 by a preset distance, and the second direction is opposite to the first direction.

The switching-on and switching-off assembly is rotationally arranged in the shell, the switching-on and switching-off assembly rotates along a first direction, the operating mechanism 100 is switched on, the switching-on and switching-off assembly rotates along a second direction, the operating mechanism 100 is switched off, and one of the first direction and the second direction is clockwise, and the other is anticlockwise. Referring to fig. 4 in combination, the trip assembly 120 includes a trip body 122 and an iron core 121 movably connected to the trip body 122, the trip assembly 120 trips, the iron core 121 is ejected from the trip body 122, the trip assembly 120 is reset, and the iron core 121 is retracted back into the trip body 122. The switching-on and switching-off assembly is interlocked with the iron core 121 of the trip assembly 120 through the reset lever 131.

Specifically, referring to fig. 18 and 19, when the trip assembly 120 is in an initial state (an unbuckled state) and the operating mechanism 100 is in a closed state, a preset distance H is provided between the iron core of the trip assembly 120 and the reset iron core; referring to fig. 7, when the remote opening operation of the operating mechanism 100 is required, the trip assembly 120 is controlled to trip, the iron core 121 is ejected outwards, and after the iron core 121 moves by the idle stroke H, the iron core is abutted against the reset lever 131 and drives the reset lever 131 to rotate, so that the closing operating mechanism 100 is opened.

After the operating mechanism 100 is opened, the iron core 121 needs to be reset for the next remote opening operation. Referring to fig. 10 and 21, the external force drives the switching-on/off assembly to rotate along a first direction for switching on, and during the rotation process, the switching-on/off assembly deforms to store energy, and drives the reset lever 131 to move towards the direction close to the trip assembly 120 so as to apply pressure to the iron core 121 to force the iron core to retract back into the trip unit body 122; referring to fig. 18 and 19 again, after the trip assembly 120 is reset, the external force acting on the switching-on/off assembly is released, the switching-on/off assembly releases energy, and rotates along the second direction and releases the driving force to the reset lever 131, so that the reset lever 131 can move in a direction away from the trip assembly 120 to be spaced from the iron core 121 by a preset distance H again.

After the trip assembly 120 is reset, the reset lever 131 may be driven by the switching-on/off assembly to move in a direction away from the trip assembly 120, or may be driven by other assemblies to move in a direction away from the trip assembly 120, which is not limited in this embodiment.

Optionally, in an implementation manner of the embodiment of the present utility model, the preset distance H is positively related to the size of the housing along the sequentially arranged direction of the reset lever 131 and the iron core 121, and the preset distance H is positively related to the movement stroke of the iron core 121.

The larger the size of the housing in the sequentially setting direction of the reset lever 131 and the iron core 121, the larger the space for setting the preset distance H; the greater the movement stroke of the iron core 121, the greater the distance that the iron core 121 can move in the direction of the reset lever 131 during tripping, and accordingly, the greater the preset distance H can be set, so that the greater speed of the iron core 121 can be obtained.

Preferably, the preset distance H is 0.1mm to 0.5mm, and when the preset distance H is less than 0.1mm, the distance between the iron core 121 and the reset lever 131 is too small, so that the iron core 121 is difficult to obtain a larger speed, and reliable tripping of the tripping assembly 120 cannot be ensured; when the preset distance H is greater than 0.5mm, the size of the housing in the direction in which the reset lever 131 and the iron core 121 are sequentially arranged is easily caused to be too large, and the position of the reset lever 131 is easily caused to be too high, so that the abutting area between the reset lever 131 and the rotating disc 163 is small, and the operating mechanism 100 is further caused to be automatically tripped; when the preset distance H is less than or equal to 0.1mm and less than or equal to 0.5mm, the iron core 121 can obtain a proper speed, so that the trip assembly 120 is ensured to trip smoothly, the reset lever 131 is driven to rotate more easily, the trip action of the operating mechanism 100 is completed, and the size of the shell is not oversized.

In one embodiment, the operation of the operating mechanism 100 is as follows:

when the operating mechanism 100 is in the opening state, the bushing plate 162 is positioned at the maximum angular position of the second direction rotation thereof due to the spring force of the energy storage spring 143; simultaneously, the shaft sleeve plate 162 is linked with the first toggle arm 1631 on the rotary disc 163 through the first toggle part 1621, so that the rotary shaft 161 and the rotary disc 163 are also positioned at the maximum angle position of the second direction rotation; the cam 151 is at a maximum position rotated in the second direction by the combined action of the closing spring 152, the second toggle arm 1632 of the rotary disc 163, the cover 112, and the base 111, as shown in fig. 14. The reset lever 131 contacts the elastic piece 1411 with the second trigger portion 1312 under the action of the second reset spring 142, and a gap H is formed between the first trigger portion 1311 and the iron core 121 of the trip assembly 120, as shown in fig. 15 and 16.

The operation mechanism 100 is switched on, the rotating shaft 161 is driven to rotate along a first direction, a first toggle arm 1631 on the rotating disc 163 is connected with the shaft sleeve plate 162 to rotate along the first direction through a first toggle part 1621 of the shaft sleeve plate 162, the shaft sleeve plate 162 is connected with a second cantilever 1432 of the energy storage spring 143 to perform first direction displacement compression, and the energy storage spring 143 performs energy storage through elastic deformation; in the process that the sleeve plate 162 rotates along the first direction, the third touching part 1622 is linked with the fourth touching part 1313 on the reset lever 131, and the left end of the reset lever 131 is tilted against the spring force of the reset spring, so that the third protruding part 1624 and the third touching part 1622 of the sleeve plate 162 slide over the lower end of the fourth touching part 1313 on the reset lever 131; as shown in fig. 17, after that, due to the spring force of the second return spring 142, the return lever 131 rotates back, and the second touching portion 1312 contacts with the elastic sheet 1411; in the process of rotating the rotating shaft 161 in the first direction, the rotating disc 163 links the cam 151 and the closing spring 152 to complete the closing operation, at this time, the rotating shaft 161 is released, the sleeve plate 162 is pushed by the second cantilever 1432 of the energy storage spring 143 to rotate in the second direction, and the third protruding part 1624 is limited by the first limiting part 1314 on the reset lever 131. At this time, the mechanism is in a state of closing and storing energy, as shown in fig. 18 and 19.

When the change-over switch is subjected to remote opening operation, a remote opening instruction is sent to the tripping assembly 120, and the iron core 121 is outwards opened; after the iron core 121 moves by the idle stroke H in the process, the reset lever 131 is linked and the spring force of the second reset spring 142 is overcome, so that the reset lever 131 rotates along the first direction; after the iron core 121 of the trip assembly 120 is completely opened, the reset lever 131 is at the maximum position rotated in the first direction, and the first limiting portion 1314 thereof releases the limitation of the third protrusion 1624 of the sleeve plate 162; as shown in fig. 20, the bushing plate 162 rotates in the second direction under the action of the energy storage spring 143, and the first toggle arm 1631 of the rotating disc 163 is linked by the first toggle part 1621 to rotate the rotating disc 163 in the second direction; the rotating disc 163 completes the opening operation with the closing spring 152 while rotating in the second direction. At this time, the iron core 121 of the trip assembly 120 contacts the first contact portion 1311 of the reset lever 131 due to the second reset spring 142, as shown in fig. 7.

When the remote opening and closing operation is performed, the driving rotation shaft 161 rotates along the first direction, the third touch part 1622 of the shaft sleeve plate 162 touches the fourth touch part 1313 on the reset lever 131, and the shaft sleeve plate 162 has a downward contact force component to the reset lever 131 through the third touch part 1622 in the continuous rotation process of the shaft sleeve plate 162 in the first direction because the third touch part 1622 is designed as an inclined plane, and the contact force component has a tendency of enabling the reset lever 131 to move towards the trip assembly 120; the increased torque rotates the rotating shaft 161 in the first direction, the third contact portion 1622 of the sleeve plate 162 is linked to the reset lever 131 through the fourth contact portion 1313 to move toward the trip assembly 120, and the first contact portion 1311 presses the iron core 121 of the trip assembly 120 to reset, as shown in fig. 10. During the resetting process of the resetting lever 131 pressing the iron core 121 of the tripping assembly 120 through the first touch part 1311, the second touch part 1312 contacts with the elastic sheet 1411; as the rotating shaft 161 rotates in the first direction, the second touching portion 1312 presses the elastic sheet 1411 to elastically deform, and as the core 121 is continuously reset, the deformation amount of the elastic sheet 1411 increases until the core 121 is completely reset, as shown in fig. 21. When the rotation shaft 161 is released, the elastic piece 1411 is elastically deformed and restored, and the second touch portion 1312 of the reset lever 131 is pushed to overcome the reset force of the second reset spring 142, so that the reset lever 131 is reset and finally stops to the initial position state of the elastic piece 1411, and at this time, a gap H is formed between the first touch portion 1311 of the reset lever 131 and the iron core 121 of the trip assembly 120, as shown in fig. 18 and 19.
