Thus, the following detailed description of the embodiments of the present invention, presented in the accompanying drawings, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.

In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate the position or positional relationship based on the position or positional relationship shown in the drawings, or the position or positional relationship which is usually placed when the product of the present invention is used, and are only for convenience of description and simplification of the description, but do not indicate or imply that the device or element referred to must have a specific position, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," "third," and the like are used solely to distinguish one from another and are not to be construed as indicating or implying relative importance.

Furthermore, the terms "horizontal", "vertical" and the like do not imply that the components are required to be absolutely horizontal or pendant, but rather may be slightly inclined. 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, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; 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 meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Referring to fig. 1 and 9, the present embodiment provides an operating device of a rotary switch, which includes an operating element and a fixing element 20 having an accommodating cavity 21, wherein the operating element is disposed in the accommodating cavity 21 in a penetrating manner; driving the motion of the motion piece in the containing cavity 21, wherein the motion piece can be switched between a locking position and a working position; the lock position limits the rotation of the action piece; when the actuator is in the working position, the trip unit 60 can be reset by the actuator.

It should be noted that the operating device of the rotary switch provided in the present embodiment not only has a function of controlling the operation of the operating mechanism of the circuit breaker, but also has a function of resetting the trip unit 60 before controlling the operation of the operating mechanism. For example, in this embodiment, an engaging portion 12 may be further disposed at one end of the actuating member close to the circuit breaker, so that the operating device of the rotary switch is engaged with the operating mechanism of the circuit breaker through the engaging portion 12, thereby implementing an opening or closing operation of the circuit breaker. It should be understood that the operating device of the rotary switch controls the operation of the operating mechanism of the circuit breaker as a basic function, and the manner in which the operating device of the rotary switch controls the operation of the operating mechanism of the circuit breaker is only an example of the embodiment, and is not a specific limitation to the implementation manner, and any feasible implementation manner can be selected by those skilled in the art as long as the operating device of the rotary switch can control the operation of the operating mechanism to perform opening or closing.

In the present embodiment, the actuator is driven to move in the housing chamber 21, and the actuator can be switched between the locking position and the working position; the lock position limits the rotation of the action piece; when the actuator is in the working position, the trip unit 60 can be reset by the actuator. The locking position can limit the operation member from rotating, and when the operation device of the rotary switch is self-locked and positioned to enter the working position, the release 60 can be reset under the action of the operation member, and at the moment, the operation member also unlocks the locking state, namely, the operation member can rotate. Therefore, the present embodiment limits the rotation of the actuator before the trip unit 60 is reset, and the actuator can rotate only after the trip unit 60 is reset when the actuator is in the operating position.

In summary, the present embodiment provides an operating device of a rotary switch, which includes an operating element and a fixing element 20 having an accommodating cavity 21, wherein the operating element is disposed in the accommodating cavity 21; driving the motion of the motion piece in the containing cavity 21, wherein the motion piece can be switched between a locking position and a working position; the lock position limits the rotation of the action piece; when the actuator is in the working position, the trip unit 60 can be reset by the actuator. Thus, the actuator cannot rotate due to the lock-position restriction before the release 60 is reset; when the actuator is moved out of the locked position and into the operating position, the actuator will act on the trip unit 60 to reset the trip unit. Therefore, compared with the prior art, the rotating switch-on and switch-off control device can rotate after the release 60 resets to control the switch-on and switch-off of the circuit breaker, so that the release 60 can be reliably reset, and the problem that the switch-on and switch-off failure is caused by the fact that the release 60 is not reset and rotating operation is carried out is avoided.

Before the release 60 is not reset, the rotating mode of the action part is limited to avoid that the release 60 rotates without being reset so as to cause the failure of opening and closing of the brake; of course, in other embodiments of the present application, before the release 60 is not reset, the rotating operation of the operating element that can rotate but cannot act on the circuit breaker can be avoided by idling the operating element so as to avoid the switching failure caused by the rotating operation of the release 60 without resetting.

The above-mentioned tripping device 60 is not reset, and the above-mentioned manner of preventing tripping device 60 from rotating without resetting and causing switching failure also includes various manners by the way of limiting the rotation of the operating member. For example, by restricting the rotation of the actuating handle 10 of the actuating member, by restricting the rotation of the abutment member 30 of the actuating member, by restricting the rotation of the actuating member by the structure of the fixing member, and so on.

For example, when the rotation of the holding member 30 is limited, the rotation of the holding member 30 may be limited before the release 60 is reset. At least two implementation forms can be included, firstly, the implementation forms are realized by a mode of limiting the rotation of one end of the holding member 30 close to the tripper 60 (for example, the rotation of one end of the holding member 30 close to the tripper 60 can be not limited only after the tripper 60 is reset by acting on the tripper 60); secondly, the rotation of the end of the abutting member 30 close to the driving handle 10 is limited (for example, the end of the abutting member 30 close to the driving handle 10 can be rotated without being limited only after the release 60 is reset). The specific implementation form of the present application is not limited as long as the rotating motion of the operating device of the rotary switch is locked before the release 60 is not reset, and the rotating motion of the operating device of the rotary switch is unlocked after the release 60 is reset, and the operating device of the rotary switch drives the circuit breaker to perform closing motion blocking in various ways, which is not listed in the present application.

The present embodiment will be exemplified below in the form of restricting the rotation of the actuating member by the driving handle 10 before the trip unit 60 is reset.

The actuating part comprises a driving handle 10 and a propping part 30, and the rotating end of the driving handle 10 is arranged in the accommodating cavity 21 in a penetrating way; the abutting piece 30 is sleeved at the rotating end 14 of the driving handle 10, the driving handle 10 is pushed to move along the axis of the accommodating cavity 21, the driving handle 10 can be switched between a locking position and a working position, and the locking position limits the rotation of the driving handle 10; when the driving handle 10 is in the working position, the abutting member 30 acts on the release 60 of the circuit breaker, and the driving handle 10 can rotate relative to the fixing member 20 to control the opening or closing of the circuit breaker. The operating means of the rotary switch can achieve reliable resetting of the trip unit 60.

The driving handle 10 is adapted to rotate in the receiving chamber 21 of the fixing member 20 or move along the central axis of the receiving chamber 21. When the driving handle 10 rotates in the receiving cavity 21 of the fixing member 20, the circuit breaker can be controlled to open or close. For example, the engaging portion 12 may be correspondingly disposed at the rotating end 14 of the driving handle 10, so that the operating device of the rotary switch engages with the operating mechanism of the circuit breaker through the engaging portion 12, thereby implementing the opening or closing operation of the circuit breaker. For example, the matching portion 12 of the operating device of the rotary switch may be a square hole, and correspondingly, the operating mechanism of the circuit breaker may be provided with a square shaft corresponding to the square hole, so as to achieve the purpose of controlling the circuit breaker by the operating device of the rotary switch through the matching of the square hole and the square shaft. It should be understood that the square hole and the square shaft are only an example given in the present application, and in other embodiments, the relative positions of the square hole and the square shaft may be interchanged, and other matching structures may be adopted.

In addition, when the driving handle 10 moves along the central axis of the accommodating cavity 21, the driving handle 10 can control the abutting piece 30 to move, so that the abutting piece 30 moves relative to the fixing piece 20 (the moving direction here is along the axial direction of the accommodating cavity 21).

For example, in the present embodiment, the above-mentioned abutting member 30 is sleeved on the rotating end 14 of the driving handle 10, and since the two are in a sleeved relationship, there is no radial limitation between the driving handle 10 and the abutting member 30, and the driving handle 10 can rotate relative to the abutting member 30.

In the present embodiment, by pushing the drive handle 10 so as to move the drive handle 10 along the axis of the accommodating chamber 21, it is possible to switch the drive handle 10 between the lock position and the working position. When the driving handle 10 is in the locking position, the driving handle 10 is locked in the radial direction, and the driving handle 10 can move axially but can not move radially (the axial direction or the radial direction is mainly oriented in the direction shown in fig. 2 or 3, the same applies below); when the driving handle 10 is pushed to move along the axis of the accommodating chamber 21, the driving handle 10 can be switched between the locking position and the working position. When the driving handle 10 is positioned in a self-locking way and enters a working position, the abutting piece 30 can act on the release 60 of the circuit breaker, so that the abutting piece 30 drives the release 60 to reset, and at the moment, the driving handle 10 can rotate relative to the fixing piece 20, and the opening or closing of the circuit breaker is controlled. Thus, in the present embodiment, when the drive handle 10 is in the lock position, the drive handle 10 cannot be rotated; only after the driving handle 10 enters the working position, the abutting member 30 acts on the release 60 of the circuit breaker, and then when the release 60 is controlled to reset, the driving handle 10 can rotate relative to the fixing member 20, and then the circuit breaker is controlled to be opened or closed through the rotation of the driving handle 10. So can effectively solve among the prior art release 60 and just operate the circuit breaker and divide-shut brake not reseing to lead to the problem of divide-shut brake inefficacy.

In summary, in the using process, the driving handle 10 can be pushed to move along the axial direction of the accommodating cavity 21, so that the driving handle 10 is self-locked and positioned to enter the working position, the supporting member 30 is driven by the driving handle 10 to act on the release 60 of the circuit breaker, and then the release 60 is reset, so that the driving handle 10 can rotate relative to the fixing member 20, and then the opening and closing of the circuit breaker are controlled. Therefore, in this embodiment, after the operating device of the rotary switch is positioned in a self-locking manner and enters a working position, the reset operation of the release 60 can be realized, and then the driving handle 10 rotates relative to the fixing member 20, so that the driving handle is used for controlling the circuit breaker to open or close. Thus, for prior art, this application can realize rotating again after tripper 60 resets in order to control circuit breaker divide-shut brake to can make tripper 60 realize reliably resetting, avoided tripper 60 not reset just to rotate the operation and lead to the problem appearance of divide-shut brake inefficacy.

Referring to fig. 4 and 5 again, optionally, a guide channel 23 is further formed on the inner wall of the accommodating cavity 21, the guide channel 23 includes a first vertical groove 231 and a first stroke groove 232 communicated with the first vertical groove 231, the first stroke groove 232 and the first vertical groove 231 form an included angle, a guide 11 is arranged on the outer wall of the driving handle 10, the guide 11 is clamped in the guide channel 23, and when the guide 11 is clamped in the first vertical groove 231, the driving handle 10 is located at the locking position; when the guide member 11 is engaged with the first stroke groove 232, the driving handle 10 is in the working position.

Thus, when the guide 11 is engaged in the first vertical slot 231, the driving handle 10 is in the locked position, and the driving handle 10 cannot rotate due to the guide 11; when the guide member 11 is engaged in the first stroke groove 232, the driving handle 10 is in the working position, and the guide member 11 can move along the first stroke groove 232, so that the driving handle 10 can rotate relative to the fixing member 20. It should be noted that, in the present embodiment, when the guiding element 11 moves from the end of the first vertical slot 231 away from the first stroke slot 232 to the intersection point of the first vertical slot 231 and the first stroke slot 232, the driving handle 10 drives the abutting element 30, so that the abutting element 30 can just act on the trip 60 (when the trip 60 is operated and reset by the reset button 61, the reset button 61 is used, and the other descriptions are the same). Specifically, the length of the first vertical slot 231 should be reasonably selected according to actual situations, and is not described in detail herein.

It should be noted that the above-mentioned guiding channel 23 is provided as an embodiment of the present application, and in other embodiments, other implementation manners may be adopted to switch the driving handle 10 between the locking position and the working position, so that the driving handle 10 is in the working position, the abutting piece 30 acts on the release 60 of the circuit breaker, and the driving handle 10 can rotate relative to the fixing piece 20 to control the opening or closing of the circuit breaker. For example, the guide member 11 may be disposed on the fixing member 20, and the guide channel 23 may be disposed on the driving handle 10, which is not limited in this application.

In this embodiment, optionally, a reset groove 24 is further formed on the inner wall of the accommodating cavity 21, and the reset groove 24 is communicated between the first vertical groove 231 and the first stroke groove 232 for resetting the guide member 11.

Illustratively, in one embodiment, the reset groove 24 includes a second vertical groove 241 and a second stroke groove 242 that communicate with each other, the second vertical groove 241 communicating between the first stroke groove 232 and the second stroke groove 242, and the second stroke groove 242 communicating between the second vertical groove 241 and the first vertical groove 231. In this way, the guide 11 can be reset sequentially through the second vertical slot 241 and the second travel slot 242 in preparation for the next depression of the reset button 61 to control the reset of the trip unit 60. Optionally, in this embodiment, the first stroke slot 232 and the second stroke slot 242 are disposed in parallel.

For example, in another embodiment, the reset slot 24 may also be a slanted slot, one end of which communicates with an end of the first stroke slot 232 away from the first vertical slot 231, and the other end of which communicates with an end of the first vertical slot 231 away from the first stroke slot 232. In this way, quick resetting of the drive handle 10 is also facilitated.

In addition, in this embodiment, in order to make the rotation or movement of the driving handle 10 relative to the fixing member 20 more stable and reliable, in this embodiment, the guide channels 23 may include two, two guide channels 23 are symmetrically disposed on the inner wall of the accommodating cavity 21, and the guide members 11 also include two, and two guide members 11 are symmetrically disposed on the outer wall of the driving handle 10. It will be appreciated that each set of guides 11 and guide channels 23 should be adapted. During movement, the two guides 11 should move in the same direction.
