Referring to fig. 1, the present embodiment provides an operating mechanism, which includes a linkage assembly 10, a driving member 20 and an acting element 30, wherein the acting element 30 is connected to the linkage assembly 10; the driving linkage assembly 10 rotates, the linkage assembly 10 drives the acting element 30 to move, and the acting element 30 is used for driving the driving element 20 to perform linear motion, so that the driving element 20 drives the moving contact 220 of the isolating switch to be close to or far away from the fixed contact 230.

The acting element 30 is connected to the linkage assembly 10, and the acting element 30 can be used to drive the driving element 20 to move, so that the driving element 20 drives the moving contact 220 to approach and act on the static contact 230, thereby implementing switching on of the disconnecting switch, or drives the moving contact 220 to move away from the static contact 230, thereby implementing switching off of the disconnecting switch.

In this embodiment, the driving element 20 is connected to the movable contact 220, so that the driving element 20 moves under the action of the acting element 30 to drive the movable contact 220 to move away from the stationary contact 230, so as to open the movable contact 220 and the stationary contact 230; after the moving contact 220 and the fixed contact 230 are switched off, the moving contact 220 can be driven to move continuously along with the driving element 20 by driving the acting element 30 to move in the opposite direction, so that the moving contact 220 is switched on continuously with the fixed contact 230.

In this embodiment, through the cooperation between the linkage assembly 10 and the acting element 30, the rotation of the linkage assembly 10 can drive the driving element 20 to translate, so that the movement stroke of the driving element 20 is larger, thereby realizing reliable switching on or switching off of the moving contact 220 and the static contact 230, and further improving the working reliability of the operating mechanism.

In summary, the present embodiment provides an operating mechanism, which includes a linkage assembly 10, a driving member 20 and an acting element 30, wherein the acting element 30 is connected to the linkage assembly 10; the driving linkage assembly 10 rotates, the linkage assembly 10 drives the acting element 30 to move, and the acting element 30 is used for driving the driving element 20 to perform linear motion, so that the driving element 20 drives the moving contact 220 of the isolating switch to be close to or far away from the fixed contact 230. In this way, in an actual operation process, the linkage assembly 10 is driven to rotate, and the linkage assembly 10 can drive the acting element 30 to move, so that the acting element 30 acts on the driving element 20, and further the driving element 20 performs a linear motion, so that the rotational motion of the linkage assembly 10 acts on the driving element 20, and further the driving element 20 performs a linear translation, so that the driving element 20 can drive the moving contact 220 to be close to the fixed contact 230 to switch on the operating mechanism, or the driving element 20 can drive the moving contact 220 to be far from the fixed contact 230 to switch off the operating mechanism. The operating mechanism provided by the application is simple in structure, and can realize that rotary motion becomes the linear translation of driving piece 20 under the effect of linkage assembly 10 and action piece 30, and the operating mechanism provided by the application can rapidly carry out switching-off or switching-on motion, so that the switching-off and switching-on speeds are improved, and further the working reliability of the operating mechanism is improved.

In this embodiment, optionally, the linkage assembly 10 is sleeved with an elastic member 40, the driving member 20 is provided with a guide slot 21, and one end of the acting member 30 extends into the guide slot 21; the acting element 30 is driven to move idle stroke in the guide groove 21, the acting element 30 moves from the first working position to the second working position, and the elastic element 40 stores energy; the acting element 30 moves from the second working position to the third working position under the condition that the elastic element 40 releases energy, so as to push the driving element 20 away from the fixed contact 230. The second working position is located between the first working position and the third working position.

One end of the acting element 30 close to the driving element 20 extends into the guiding groove 21 of the driving element 20, so that the acting element moves in the guiding groove 21 to abut against the groove wall of the guiding groove 21, and then the driving element 20 is driven to move by the groove wall acting on the guiding groove 21, so that the driving element 20 drives the moving contact 220 and the static contact 230 to perform opening or closing.

The guide groove 21 is used to move the acting element 30 so that the acting element 30 can make an idle stroke in the guide groove 21, and may also act on a groove wall of the guide groove 21 to drive the driving element 20 to move. Therefore, in the present embodiment, the guide groove 21 may be recessed on the side of the driving element 20 close to the linkage assembly 10 (i.e. the guide groove 21 does not penetrate through the driving element 20), or may be penetrated through the driving element 20.

In addition, referring to fig. 1, when the initial position of the operating mechanism is the switch-on position, the first working position is the working position of the acting element 30 in the initial state (at this time, the elastic element 40 is in the free state without being stressed, and the movable contact 220 acts on the fixed contact 230, so that the disconnector is switched on). The second working position refers to the working position of the elastic member 40 after the energy storage is completed, please refer to fig. 5. The third working position refers to a working position where the acting element 30 drives the moving contact 220 to separate from the stationary contact 230, and the disconnecting switch is opened, please refer to fig. 6.

When the operating mechanism needs to be switched on after switching off, the linkage assembly 10 needs to be driven to rotate reversely, so that the acting element 30 is driven to return to the first working position from the third working position. That is, the movement of the operating mechanism is a reciprocating reversible movement, the operating mechanism has three working positions from closing to opening (i.e. sequentially passing through the first working position, the second working position and the third working position), and also has three working positions from opening to closing (i.e. sequentially passing through the third working position, the second working position and the first working position). It should be understood that the first operating position is an initial position, the second operating position is a position where the elastic member 40 completes the compression energy storage, and the third operating position is a position where the opening or closing is completed. That is, the three working bits are functional bits and are only relative positions, which should not be considered as limiting the specific positions of the three working bits. Since the principle of the opening and closing process is the same, for convenience of description and understanding, the following description will take the initial position of the operating mechanism as the closing position as an example.

When the moving contact 220 and the fixed contact 230 need to be opened, the acting element 30 moves in the forward direction of the guide slot 21, the acting element 30 moves from the first working position to the second working position, and at this time, the elastic element 40 is pressed to store energy; the acting element 30 moves to the second working position, and the energy storage of the elastic element 40 is completed; when the elastic element 40 releases energy, the acting element 30 can move from the second working position toward the third working position, and at this time, the acting element 30 is forced to accelerate under the driving action of the elastic element 40, and then the acting element 30 pushes the driving element 20 to move forward, so that the driving element 20 moves to push the moving contact 220 to be away from the fixed contact 230, thereby achieving the opening.

Similarly, when the moving contact 220 and the fixed contact 230 need to be switched on, the acting element 30 is driven to move in the guide groove 21 in the opposite direction, the acting element 30 moves from the third working position to the second working position, and at this time, the elastic element 40 is pressed to store energy; the acting element 30 moves to the second working position, and the energy storage of the elastic element 40 is completed; when the elastic element 40 releases energy, the acting element 30 can move from the second working position toward the first working position, and at this time, the acting element 30 is forced to accelerate under the driving action of the elastic element 40, and then the acting element 30 pushes the driving element 20 to move in the opposite direction, so that the driving element 20 moves to push the moving contact 220 to be close to the fixed contact 230, thereby implementing closing. Therefore, the operating mechanism can realize the switching-off or switching-on of the moving contact 220 and the static contact 230 through the energy storage of the elastic element 40 and the energy release of the elastic element 40.

Thus, in actual operation, the acting element 30 is driven to move in the guide slot 21 of the driving element 20, so that the acting element 30 can move from the first working position to the second working position, and at the moment, the elastic element 40 is compressed to store energy; when the acting element 30 is in the second working position, the energy storage action of the elastic element 40 is completed; at this time, the elastic element 40 releases energy, the acting element 30 abuts against the side wall of the guide slot 21, so as to push the driving element 20 to move, so that the acting element 30 moves to the third working position, and at this time, the driving element 20 pushes the moving contact 220 to move away from or close to the static contact 230, so that the moving contact 220 and the static contact 230 are opened or closed. The operating mechanism provided by the application is simple in structure, the moving contact 220 and the static contact 230 can rapidly perform switching-off or switching-on motion under the action of the elastic element 40, the switching-off and switching-on speeds are increased, and the working reliability of the operating mechanism is further improved.

Referring to fig. 1, optionally, in an embodiment, the linkage assembly 10 includes a first linkage member 11 and a second linkage member 12, the elastic member 40 is sleeved on the second linkage member 12, the acting member 30 is connected to the first linkage member 11, the second linkage member 12 is provided with a sliding slot 121, the acting member 30 is slidably connected in the sliding slot 121, and an end of the acting member 30 away from the first linkage member 11 extends into the guide slot 21 for driving the driving member 20 to approach or depart from the stationary contact 230.

The acting element 30 may be connected to the first link 11 in a separate structure, or may be a protrusion 111 extending from the first link 11 toward the second link (that is, the acting element 30 may be a part of the first link 11).

The sliding slot 121 provided on the second linkage member 12 is used for the action member 30 to slide inside, in this embodiment, the first linkage member 11 is a driving member, and the second linkage member 12 is a driven member, that is, the second linkage member 12 is driven by the first linkage member 11 during movement. Thus, when the acting member 30 slides in the guide groove 21, the acting member 30 can also slide in the slide groove 121 of the second linking member 12. The elastic element 40 is sleeved on the second linkage element 12 and used for driving the elastic element 40 to compress and store energy under the action of the acting element 30.

In another embodiment, the linkage assembly 10 optionally includes a first linkage member 11 and a second linkage member 12, the elastic member 40 is sleeved on the second linkage member 12, the acting member 30 is connected to the second linkage member 12, the first linkage member 11 is provided with a sliding slot 121, the acting member 30 is slidably connected in the sliding slot 121, and an end of the acting member 30 away from the second linkage member 12 extends into the guide slot 21 for driving the driving member 20 to approach or depart from the stationary contact 230.

In this embodiment, the difference from the previous embodiment is the positions of the engaging element 30 and the slide groove 121. That is, in this embodiment, the acting element 30 of the foregoing embodiment is provided on the second link 12, and correspondingly, the slide groove 121 is provided on the first link 11. In this way, it will be the first linkage piece 11 that moves, driving the acting element 30, which is slidingly connected in the slide slot 121 of the first linkage piece 11, in motion. Since the basic principle of this embodiment is the same as that of the foregoing embodiment, the working principle of this embodiment can be inferred from the foregoing embodiment, and will not be described herein again.

In the present embodiment, the acting element 30 is located at the second operating position, and the acting element 30 abuts against the side wall of the guide groove 21 close to the stationary contact 230 (corresponding to the right side wall of the guide groove 21 in fig. 5). In this way, when the elastic element 40 is pressurized and the energy storage is completed, the acting element 30 is just abutted against the inclined wall of the trapezoidal groove, so that when the elastic element 40 releases the energy storage, the stroke of the acting element 30 pushing the driving element 20 to move can be increased under the action of the elastic element 40, so that the driving element 20 drives the movable contact 220 to realize a larger movement stroke, thereby ensuring effective opening.

Of course, the acting element 30 may also have a slight clearance from the inclined wall of the trapezoidal groove when the operating mechanism is in the second working position.

For example, in the present embodiment, the guide groove 21 may be any one of a trapezoidal groove, a rectangular groove, and a triangular groove. It should be understood that no matter what the shape of the guide slot 21 is, it should be avoided to interfere with the opening of the movable contact 220 with respect to the stationary contact 230 or the closing of the movable contact 230.

In order to further improve the reliability of the translational motion of the driving member 20, in the embodiment, the driving member 20 is slidably disposed on the housing 210 of the isolating switch, and the sliding direction of the driving member 20 is collinear with the connecting line between the driving member 20 and the stationary contact 230. For example, a slide rail may be disposed on the driving member 20, the sliding slot 121 may be disposed on the housing 210, and the sliding slot 121 and the slide rail are adapted, so that the moving direction of the driving member 20 is guided by the sliding slot 121 on the housing 210, and the operational reliability of the driving member 20 may be further improved.

In this embodiment, referring to fig. 2 and fig. 3, optionally, the operating mechanism further includes a compression spring element 50 sleeved on the second linkage element 12, one end of the elastic element 40 is connected to the second linkage element 12, and the other end of the elastic element abuts against the compression spring element 50.

Due to the action of the compressed spring member 50, when the acting member 30 moves from the first working position to the second working position, the acting member 30 can push the compressed spring member 50 to move from the end of the second linkage member 12 close to the first linkage member 11 toward the end far from the first linkage member 11, and at this time, the compressed spring member 50 compresses the elastic member 40, so that the elastic member 40 is compressed to store energy. Similarly, when the operating member 30 moves from the second operating position to the third operating position, the acting force of the operating member 30 on the compression spring member 50 is released, and at this time, the compression spring member 50 drives the compression spring member 50 to move towards the first linkage member 11 under the elastic restoring force of the elastic member 40, so as to react on the first linkage member 11 to drive the first linkage member 11 to move.

The compression spring 50 may be a pressing plate sleeved on the second linkage member 12, or a pressing block slidably connected to one side of the second linkage member 12.

In this embodiment, referring to fig. 3, the compression spring element 50 may include a first body 51 and a limit flange 52 extending from the first body 51 toward the elastic element 40, the limit flange 52 and the first body 51 enclose a limit cavity 53, and one end of the elastic element 40 close to the first body 51 abuts against a bottom of the limit cavity 53.

The limiting flange 52 may include a plurality of limiting flanges 52, and the plurality of limiting flanges 52 are uniformly distributed on the periphery of the first body 51. For example, the first flange may comprise four.

Optionally, the operating mechanism further comprises a handle 60, the handle 60 is connected to an end of the first linkage member 11 away from the elastic member 40, the handle 60 can be rotated to drive the linkage assembly 10 to rotate, and the linkage assembly 10 is used for driving the acting member 30 to move in the guide slot 21 to push the driving member 20 to move linearly. The handle 60 is provided to facilitate the rotation of the drive linkage assembly 10 to drive the movement of the acting element 30 and thus the movement of the acting element 30 within the guide slot 21. For example, the handle 60 may drive an end of the first linkage member 11 away from the second linkage member 12 to move the acting member 30.

Referring to fig. 1, optionally, the handle 60 includes a second body 61 and a driving groove 62 disposed in the second body 61, one end of the first link 11 close to the handle 60 is provided with a protrusion 111, and the protrusion 111 extends into the driving groove 62; the driving handle 60 is rotated and the groove wall of the driving groove 62 acts on the protrusion 111 to move the end of the first linkage member 11 adjacent to the guide groove 21 in the guide groove 21.

For example, referring to fig. 4 to fig. 7, when the operating mechanism is in a closed state, the protrusion 111 abuts against the first groove wall 621 of the driving groove 62 (at this time, the protrusion 111 moves to the first moving position, and the protrusion 111 abuts against the bottom end of the first groove wall 621 in the first moving position), referring to fig. 4, the elastic member 40 is in a free state; when the driving acting element 30 needs to move in the guide slot 21, so that the elastic element 40 is compressed to store energy, the first slot wall 621 of the driving slot 62 drives the protrusion 111 to move from one end of the first slot wall 621 to the other end of the first slot wall 621 (i.e. the protrusion 111 moves to the second moving position, and the protrusion 111 abuts against the top end of the first slot wall 621 when in the second moving position), please refer to fig. 5, at this time, the compression and energy storage of the elastic element 40 is completed; at this time, if the elastic element 40 releases the energy, the protrusion 111 moves in the driving groove 62 under the action of the elastic element 40 to move from the first groove wall 621 to the second groove wall 622 of the driving wall (i.e. the protrusion 111 moves to the third movement position, and the protrusion 111 abuts against the bottom end of the second groove wall 622 in the third movement position), as shown in fig. 6, at this time, the energy release of the elastic element 40 is finished, and the protrusion 111 is located at one end of the second groove wall 622 close to the first groove wall 621.

If the switch needs to be switched on, the driving handle 60 rotates reversely (i.e. the rotation direction is opposite to the rotation direction when the operating mechanism is driven to switch off), so that the protrusion 111 can be driven to move from the bottom end of the second groove wall 622 to the top end of the second groove wall 622 (at this time, the protrusion 111 rotates from the third movement position to the second movement position), as shown in fig. 7, at this time, the elastic member 40 performs compression energy storage; when the elastic element 40 releases energy, the protrusion 111 moves through an idle stroke in the driving slot 62 under the action of the elastic element 40 (at this time, the protrusion 111 rotates from the second motion position to the first motion position), and the protrusion 111 moves from the top end of the second slot wall 622 to the bottom end of the first slot wall 621, at this time, the elastic element 40 releases energy, and the operating mechanism drives the moving contact 220 and the static contact 230 to close.

In the present embodiment, the handle 60 has a steering function, that is, switching on or off of the operating mechanism can be realized by reversing the handle 60. Specifically, in the present embodiment, referring to fig. 10, when the handle 60 is at the pull-down position, the operating mechanism is in the open state; when the handle 60 is in the push-up state, the operating mechanism is in the closed state. Thus, under the steering action of the handle 60, the switching-on position of the operating mechanism can be converted from the original pull-down position to the push-up position, and the switching-off position of the operating mechanism is converted from the original pull-up position to the pull-down position, so that the operating habit of a technician is better met.

In the present embodiment, the acting element 30 is located at the second working position, and the protrusion 111 abuts against the sidewall of the driving groove 62 close to the stationary contact 230 and is located at a side of the driving groove 62 away from the first linking member 11 (i.e. the protrusion 111 abuts against a top end of the first groove wall 621). Thus, when the compressed energy storage is completed, the elastic element 40 just abuts against the right side wall of the driving groove 62 by the protrusion 111.

Illustratively, the driving groove 62 may be any one of a trapezoidal groove, a rectangular groove, or a triangular groove. It should be understood that whatever the shape of the driving slot 62, it is necessary to avoid interference with the opening of the movable contact 220 with respect to the stationary contact 230 or the closing of the stationary contact 230.

When the driving groove 62 is a triangular groove, it is shown in fig. 4 to 7. When the driving groove 62 is a triangular groove, the protrusion 111 is located at the first moving position and the third moving position, and the protrusion 111 abuts against the boundary between the first groove wall 621 and the second groove wall 622. In addition, the foregoing references to the bottom end and the top end are made to the orientation shown in fig. 1 or fig. 4-7, for example, and should not be construed as limiting the present application.

It should be understood that the shape of the driving slot 62, the shape of the guiding slot 21, the moving path of the acting element 30 and the moving path of the movable contact 220 are configured to be adapted to each other.

Referring to fig. 8 to 9, in order to facilitate the operation of the handle 60 by the operator, optionally, the handle 60 is provided with a grip ring 63.

It should be noted that the grip ring 63 is used for the operator to manually grip, so that the overall rotation of the handle 60 is controlled by rotating the grip ring 63, and therefore, the size of the grip ring 63 should be adapted to the hand of the human body. In this embodiment, the holding ring 63 is a square ring for facilitating the holding of the operator.

In order to enhance the comfort of the operator when gripping, in the present embodiment, the outer wall surface and the inner wall surface of the grip ring 63 are both arc surfaces.

The grip ring 63 may be formed by first forming a body of the grip ring 63 by injection molding, and then forming an arc-shaped soft rubber surface on the outer periphery of the grip ring 63 by performing secondary injection molding on the body. Thus, the hand feeling is better when the operator holds the handle.

Optionally, referring to fig. 8 and 9, the grip ring 63 is further provided with a rib 631. Wherein, the ribs 631 may be uniformly distributed on the outer circumference of the grip ring 63.

In the present embodiment, the operation end is an end away from the acting element 30, and is also an end for the operator to hold. The operation end is provided with a reinforcing rib 631 to reinforce the strength of the operation end of the handle 60, so that the situation that the operation end cracks or even breaks when an operator manually pulls the handle 60 to rotate is avoided. Of course, in order to further enhance the strength of the handle 60, in addition to the ring-shaped reinforcing rib 631 surrounding the grip hole at the outer periphery of the operation end, a reinforcing rib 631 may be correspondingly added at other places of the handle 60. For example, at one end of the handle 60 close to the first linkage piece 11, the strength of the handle 60 close to the first linkage piece 11 can be enhanced, so that the influence of the driving groove 62 arranged on the handle 60 on the strength of the handle 60 can be eliminated.

The operation principle of the operating mechanism provided in this embodiment is described by taking the initial state of the operating mechanism as the closed state as an example, as follows:

initial state: referring to fig. 4, at this time, the handle 60 is located at the switching-on position, the protrusion 111 on the first linking member 11 abuts against the bottom end of the first groove wall 621 of the driving groove 62 (the protrusion 111 is located at the first moving position), the acting member 30 is located at the first working position, the elastic member 40 is in the free state, the driving member 20 is located at the switching-on position, and the movable contact 220 and the fixed contact 230 are switched on.

And (4) energy storage state: referring to fig. 5 again, the operator holds the grip ring 63 and drives the handle 60 to rotate, so that the handle 60 drives the protrusion 111 on the first linking member 11 to move through the driving groove 62, and the protrusion 111 moves the first linking member 11, so that the acting member 30 moves from the first working position to the second working position in the guide groove 21 by an idle stroke (in this process, the protrusion 111 simultaneously moves from the bottom end of the first groove wall 621 to the top end of the first groove wall 621, that is, the protrusion 111 moves from the first moving position to the second moving position), at this time, the limiting flange 52 moves away from the first linking member 11 under the action of the first linking member 11, and the elastic member 40 is compressed to store energy.

Energy release state: referring to fig. 5 and fig. 6, when the elastic element 40 releases energy, the limiting flange 52 moves toward the first driving element 20 under the action of the elastic element 40, so that the acting element 30 abuts against the groove wall of the guiding groove 21, and further the driving element 20 is pushed to move (at this time, the acting element 30 moves from the second working position to the third working position, and the protrusion 111 moves from the second working position to the third working position, that is, the protrusion 111 moves from the top end of the first groove wall 621 to the bottom end of the second groove wall 622), and the driving element 20 drives the moving contact 220 to separate from the static contact 230, thereby achieving the opening operation.

The utility model discloses an on the other hand still provides a isolator, and this isolator includes foretell operating device.

The operating mechanism may be installed in the housing 210 of the disconnecting switch, wherein the grip ring 63 of the handle 60 is exposed outside the housing 210. Thus, the opening or closing of the disconnecting switch can be controlled by driving the holding ring 63 to move.

In addition, in the embodiment, referring to fig. 10, when the disconnecting switch is vertically installed, the handle 60 is disposed at one side of the disconnecting switch, and the handle 60, the first linkage member 11 and the second linkage member 12 are respectively rotatably connected to the housing 210, wherein a rotation center of the first linkage member 11 is located between a rotation center of the handle 60 and a rotation center of the second linkage member 12. And the handle 60, the first linkage member 11 and the second linkage member 12 are installed on the same horizontal line (it should be understood that the horizontal refers to a horizontal line in terms of a vertical line, and is not an absolute horizontal line), while the driving member 20 is slidably connected to the housing 210, and the moving direction of the driving member 20 is a vertical direction, i.e. the moving direction of the driving member 20 is perpendicular to the installation direction of the handle 60.

Also, in this embodiment, the handle 60 is pushed up, and the disconnector is closed; the handle 60 is pulled downward and the disconnector is switched off. Thus, the method is more suitable for the operation habit and the habitual cognition of people. Meanwhile, because the gravity is downward, the moving contact 220 can move upward to be a switch-on state and the moving contact 220 can move downward to be a switch-off state due to safety consideration.
