[0047] Figure 1 This is a schematic structural diagram of an operating mechanism in an embodiment of the present application at a first viewing angle; Figure 2 This is a schematic diagram of the structure of an operating mechanism in an embodiment of the present application at a second viewing angle; Figure 3 This is a structural schematic diagram of an operating mechanism in an embodiment of the present application at a third viewing angle; Figure 4 Schematic diagram of the internal structure of the operating mechanism in one embodiment of the present application. Figures 1 to 4 As shown, the operating mechanism provided in this embodiment includes a bracket 100 and an input shaft 400, an output shaft 500, a rotating member 131, a jumper 200, a lever member 300, a re-fastener 600 and a locking member 700 rotatably connected to the bracket 100.

The input shaft 400 is transmission-connected to the lever member 300 to drive the lever member 300 to rotate, and the jumper 200 is connected to the rotating member 131 through the first connecting rod assembly 210, and the first connecting rod assembly 210 is connected to the rotating member 131 through the first elastic member 214 (see Figures 5 to 7 ) is connected to the lever member 300, the rotating member 131 is transmission-connected to the output shaft 500 to drive the output shaft 500 to rotate, and the output shaft 500 is used to be transmission-connected to the external moving contact assembly. The operating mechanism has a closing state and an opening state. In the closing state and the opening state, the tripping member 200 is located at the first tripping position. In the closing state, the lever member 300 is in the first lever position, and the first connecting rod assembly 210 can drive the rotating member 131 to rotate to the first rotation position under the traction of the first elastic member 214. In the opening state, the lever member 300 is in the second lever position, and the first connecting rod assembly 210 drives the rotating member 131 to rotate to the second rotation position under the traction of the first elastic member 214. By driving the rotating member 131 to rotate between the first rotation position and the second rotation position, the output shaft 500 is driven to rotate, so that the external moving contact assembly transmission-connected to the output shaft 500 can contact or leave the static contact assembly, that is, the connection and disconnection of the circuit are realized.

[0048] The refastener 600 and the lock member 700 are used to lock the tripping member 200 at the first tripping position. In addition, in the closed state, the refastener 600 and the lock member 700 can be unlocked under the action of an external force, so that the tripping member 200 can rotate to the second tripping position under the traction of the first elastic member 214, and at the same time, the first elastic member 214 drives the rotating member 131 to the second rotation position to disconnect the circuit.

[0049] In this embodiment, the input shaft 400 is manually rotated by the user to switch the operating mechanism between the open state and the closed state to connect and disconnect the circuit. For easy operation, a handle 410 is provided at the end of the input shaft 400. In this embodiment, the handle 410 is a knob.

[0050] In the present embodiment, the bracket 100 includes a first side plate 110, a second side plate 120, a tripping shaft 160 and a mechanism main shaft 130 which are arranged at intervals. The first side plate 110 and the second side plate 120 are arranged at intervals, and can be arranged in parallel and at intervals. The two ends of the tripping shaft 160 are respectively connected to the first side plate 110 and the second side plate 120, the two ends of the mechanism main shaft 130 are respectively connected to the first side plate 110 and the second side plate 120, the tripping member 200, the rotating member 131 and the first connecting rod assembly 210 are all located between the first side plate 110 and the second side plate 120, the tripping member 200 is connected to the tripping shaft 160, and the rotating member 131 is connected to the mechanism main shaft 130. It should be understood that the jumper 200 is rotatably connected to the bracket 100 through the jumper shaft 160, that is, the jumper shaft 160 can be rotatably connected to the first side plate 110 and the second side plate 120, or the jumper shaft 160 can be rotatably connected to the jumper 200; similarly, the rotating member 131 can be rotatably connected to the mechanism main shaft 130, or the mechanism main shaft 130 can be rotatably connected to the first side plate 110 and the second side plate 120. By setting the bracket 100 to include the first side plate 110 and the second side plate 120, the jumper 200, the rotating member 131 and the first connecting rod assembly 210 can be surrounded inside the bracket 100, thereby improving the protection of the jumper 200, the rotating member 131 and the first connecting rod assembly 210.

[0051] In this embodiment, the lever member 300 includes a first connection portion 310, a second connection portion 320 and an intermediate connection portion 330. The first connection portion 310 and the second connection portion 320 are rotatably connected to the first side plate 110 and the second side plate 120 respectively, the intermediate connection portion 330 is connected to the first connection portion 310 and the second connection portion 320, and the first elastic member 214 is connected to the intermediate connection portion 330. In this embodiment, the first connection portion 310 and the second connection portion 320 are respectively attached to and rotatably connected to the inner sides of the first side plate 110 and the second side plate 120, and the stability is better.

[0052] Further, the input shaft 400 is rotatably connected to the first side plate 110 and the second side plate 120, and both ends of the input shaft 400 are transmission-connected to the lever member 300. Specifically in this embodiment, both ends of the input shaft 400 extend outwardly of the first side plate 110 and the second side plate 120, and are transmission-connected to the lever member 300 through the second connecting rod assembly 350. The input shaft 400 is rotatably connected to the first side plate 110 and the second side plate 120, and has good stability. In addition, the two second connecting rod assemblies 350 are respectively located on the outside of the first side plate 110 and the second side plate 120 and connected to the input shaft 400, so that the force of the input shaft 400 is balanced, the axis is not easily deflected, and the stability and durability are good.

[0053] In this embodiment, the second connecting rod assembly 350 includes a third connecting rod 351 and a fourth connecting rod 352. The third connecting rod 351 is fixedly connected to the input shaft 400 (i.e., it cannot rotate relative to each other), and is rotatably connected to one end of the fourth connecting rod 352, and the other end of the fourth connecting rod 352 is fixedly connected to the lever member 300 (i.e., it cannot rotate relative to each other). Specifically, the fourth connecting rod 352 in one of the second connecting rod 212 mechanisms is connected to the first connecting portion 310 of the lever member 300, and the fourth connecting rod 352 in the other second connecting rod 212 mechanism is connected to the second connecting portion 320 of the lever member 300. In order to prevent the input shaft 400 and the third connecting rod 351 from rotating relative to each other, in this embodiment, the cross-section of the portion where the input shaft 400 and the third connecting rod 351 cooperate is a polygon.

[0054] In this embodiment, the first connecting rod assembly 210 includes a first connecting rod 211 and a second connecting rod 212. One end of the first connecting rod 211 is rotatably connected to the jumper 200, the other end of the first connecting rod 211 is rotatably connected to one end of the second connecting rod 212, and the other end of the second connecting rod 212 is rotatably connected to the rotating member 131. One end of the first elastic member 214 is connected to the hinge between the first connecting rod 211 and the second connecting rod 212. In this embodiment, the first connecting rod 211 and the second connecting rod 212 are rotatably connected through the hinge shaft 213, and the first elastic member 214 is connected to the hinge shaft 213. In other embodiments, the position of the first elastic member 214 connected to the first connecting rod assembly 210 can be adjusted, for example, it can be connected to one end of the first connecting rod 211 close to the second connecting rod 212, or it can be connected to one end of the second connecting rod 212 close to the first connecting rod 211. Optionally, the first elastic member 214 is a tension spring.

[0055] In order to improve the stability of the first connecting rod assembly 210, in this embodiment, the first connecting rod assembly 210 includes two first connecting rods 211 spaced apart from each other and two second connecting rods 212 spaced apart from each other, a part of the jumper 200 is located between the two first connecting rods 211 and is rotatably connected to the first connecting rod 211, and a part of the rotating member 131 is located between the two second connecting rods 212 and is rotatably connected to the second connecting rods 212. The two first connecting rods 211 and the two second connecting rods 212 are all connected to the same hinge shaft 213.

[0056] In the embodiment of the present application, the input shaft 400 is located within a circular range whose diameter is the line connecting the rotation axis of the jumper 200 and the rotation axis of the lock member 700. Figure 5 As shown in the dotted circle C. By such arrangement, the input shaft 400 can be located in the middle of the entire operating mechanism, and other moving parts surround the input shaft 400. When the input shaft 400 is operated, the mechanism can be subjected to balanced forces, so that the stability of the operating mechanism is better.

[0057] In this embodiment, the jumper 200 is provided with an avoidance groove 201, and when the jumper 200 is in the first jumper position, a part of the input shaft 400 is located in the avoidance groove 201. The avoidance groove 201 can make the structure more compact and avoid mutual interference between the jumper 200 and the input shaft 400.

[0058] In this embodiment, the first side plate 110 and the second side plate 120 are respectively provided with a first arc hole 111 and a second arc hole 121, one end of the rotating member 131 is connected to the first connecting rod assembly 210, and the other end is connected to the sliding shaft 132, the mechanism main shaft 130 is connected between the two ends of the rotating member 131, the two ends of the sliding shaft 132 are respectively slidably matched with the first arc hole 111 and the second arc hole 121, and at least one end of the sliding shaft 132 is transmission-connected to the output shaft 500. Specifically in this embodiment, the output shaft 500 is rotationally connected to the second side plate 120, and one end of the sliding shaft 132 extends to the outside of the second side plate 120 and is transmission-connected to the output shaft 500 through the third connecting rod assembly 510. In this embodiment, the first arc-shaped hole 111 and the second arc-shaped hole 121 extend around the rotation axis of the rotating member 131. When the rotating member 131 rotates from the first rotation position to the second rotation position, the sliding shaft 132 also slides from one end of the first arc-shaped hole 111 and the second arc-shaped hole 121 to the other end. In the figure, when the rotating member 131 is in the first rotation position, the sliding member is at the upper end of the first arc-shaped hole 111 and the second arc-shaped hole 121, and when the rotating member 131 is in the second rotation position, the sliding member is at the lower end of the first arc-shaped hole 111 and the second arc-shaped hole 121.

[0059] In this embodiment, the third connecting rod assembly 510 includes a fifth connecting rod 511 and a sixth connecting rod 512. One end of the fifth connecting rod 511 is rotatably connected to the sliding shaft 132, and the other end is rotatably connected to the sixth connecting rod 512. The sixth connecting rod 512 is fixedly connected to the output shaft 500 (i.e., it cannot rotate relative to the output shaft 500). Therefore, when the sliding shaft 132 slides along the first arc hole 111 and the second arc hole 121, the output shaft 500 can be driven to rotate through the fifth connecting rod 511 and the sixth connecting rod 512, thereby realizing power on and power off.

[0060] Figures 5 to 7 The schematic diagram of the operating mechanism in one embodiment of the present application in the closed, open and tripped states, respectively. As shown in the figure, when the operating mechanism is in the closed state, the shape of the first connecting rod assembly 210 remains stable under the pulling force of the first elastic member 214, the angle between the first connecting rod 211 and the second connecting rod 212 is greater than 150°, the rotating member 131 is in the first rotation position, the sliding shaft 132 is at the upper end of the first arc hole 111 and the second arc hole 121, and the jumper 200 cannot rotate clockwise due to being locked by the locking member 700. When the operating mechanism switches from the closed state to the open state, it is only necessary to rotate the input shaft 400 counterclockwise, and the second connecting rod assembly 350 drives the lever member 300 to rotate counterclockwise, so that the pulling direction of the first elastic member 214 changes, causing the first connecting rod assembly 210 to change shape, and the first connecting rod 211 rotates clockwise, and the second connecting rod 212 drives the rotating member 131 to rotate counterclockwise, thereby rotating to the second rotation position, that is, switching to the open state, and the circuit is disconnected.

[0061] In this embodiment, the refastener 600 has an abutting position and a releasing position in its rotational stroke, and the lock member 700 has a locking position and an unlocking position in its rotational stroke. A second elastic member 730 is disposed between the lock member 700 and the bracket 100, and the second elastic member 730 provides a force for the lock member 700 to rotate toward the unlocking position. Figure 4 and Figure 5 As shown, when the operating mechanism is in the closing state and the opening state, the abutting surface of the refastener 600 in the abutting position abuts against the lock catch 700 in the locking position, and the lock catch 700 and the jump catch 200 overlap to lock the jump catch 200 in the first jump catch position. It can be understood that the lock catch 700 is limited by the abutting effect of the refastener 600, so that it cannot rotate to the unlocking position under the action of the second elastic member 730, thereby maintaining the overlap with the jump catch 200.

[0062] Figure 8 This is a schematic diagram of a fastener 600 and a locking fastener 700 in an embodiment of the present application at a first viewing angle; Fig. 9 Schematic diagram of a fastener 600 and a lock fastener 700 in a second viewing angle in an embodiment of the present application. Figures 5 to 9 In the embodiment of the present application, the refastener 600 can be rotated from the contact position to the release position due to external force. For example, the external overload protection mechanism will be triggered when encountering a large current, thereby driving the refastener 600 to rotate, or the remotely controlled tripping mechanism drives the refastener 600 to rotate after receiving a tripping command. Figure 7 As shown, when the refastener 600 rotates to the release position, the abutting surface of the refastener 600 is released from abutment with the lock member 700, so that the lock member 700 rotates to the unlocking position under the traction of the second elastic member 730; the lock member 700 in the unlocking position releases the overlapped fit with the jumper 200, so that the jumper 200 can rotate to the second jumper position under the traction of the first elastic member 214, and the first connecting rod assembly 210 can drive the rotating member 131 to rotate to the second rotation position under the traction of the first elastic member 214. Optionally, the second elastic member 730 is a torsion spring.

[0063] like Figure 5 As shown in FIG. 1 , when the operating mechanism is in the closed state, the first elastic member 214 is located on the left side of the rotation axis of the tripping member 200. Therefore, when the locking member 700 is unlocked, the first connecting rod 211 and the tripping member 200 will rotate clockwise under the traction of the first elastic member 214, so that the tripping member 200 can rotate to the second tripping position and abut against the first limit member 140, that is, reach the tripping state, as shown in FIG. Figure 7 At the same time, the second connecting rod 212 drives the rotating member 131 to rotate to the second rotating position.

[0064] In this embodiment, one end of the lock member 700 is provided with an overlap portion 710, and the overlap portion 710 is used to overlap and cooperate with the jumper 200, and the other end of the lock member 700 is used to abut against the re-fastener 600. The lock member 700 is rotatably connected to the bracket 100 through the lock shaft 170. Specifically, the two ends of the lock shaft 170 are respectively connected to the first side plate 110 and the second side plate 120, and the lock member 700 is sleeved on the lock shaft 170.

[0065] In this embodiment, the refastener 600 includes an axle body rotatably connected to the bracket 100, and the two ends of the axle body are rotatably connected to the first side plate 110 and the second side plate 120 respectively. A part of the outer peripheral surface of the axle body forms an abutting surface. In other words, under the premise that the outer peripheral surface of the axle body abuts against the lock member 700, the lock member 700 can be kept in the locked position. A groove body 610 is provided on the outer peripheral side of the axle body. In the process of the refastener 600 rotating from the abutting position to the release position, the end of the lock member 700 loses the abutment of the abutting surface and abuts into the groove body 610, so that the lock member 700 rotates to the unlocking position. In this embodiment, when the lock member 700 rotates to the unlocking position, its end will abut against the wall of the groove body 610, thereby preventing it from continuing to rotate, so that the lock member 700 is kept in the unlocking position under the force balance between the second elastic member 730 and the wall of the groove body 610.

[0066] In this embodiment, a third elastic member 630 is provided between the refastener 600 and the bracket 100, and the third elastic member 630 is used to provide a force for the refastener 600 to rotate from the release position to the abutment position. By providing the third elastic member 630, the refastener 600 will not spontaneously rotate from the abutment position to the release position to cause the lock member 700 to be unlocked, thereby ensuring the normal use of the operating mechanism. Only under external force can the refastener 600 overcome the elastic force of the third elastic member 630 and rotate from the abutment position to the release position, thereby achieving unlocking. Optionally, the third elastic member 630 is a torsion spring.

[0067] It should be understood that when the locking member 700 is in the unlocked position, its end is pressed into the groove 610 of the refastening member 600, and the refastening member 600 is limited by the locking member 700 and cannot be restored to the abutting position under the action of the third elastic member 630.

[0068] In the present embodiment, the lever member 300 is provided with a push portion 340, and in the process of the lever member 300 rotating from the first lever position to the second lever position, the push portion 340 can push the jumper 200 to rotate from the second jumper position to the first jumper position. In the present embodiment, the push portion 340 is connected to the third connecting portion. Further, the lock member 700 is provided with a stopper 720, and the stopper 720 is used to abut against the jumper 200 in the process of the jumper 200 rotating from the second jumper position to the first jumper position, so that the lock member 700 in the unlocking position is driven by the jumper 200 to rotate to the locking position. In the present embodiment, the stopper 720 is arranged between the two ends of the lock member 700. When the locking member 700 is rotated to the locking position, the end of the locking member 700 away from the overlapping portion 710 moves out of the groove 610 of the refastener 600, and the refastener 600 is driven by the third elastic member 630 to rotate to the abutment position again. The outer peripheral surface of the refastener 600 can abut the end of the locking member 700. At this time, the locking member 700 is fixed in the locking position again.

[0069] Through the above-mentioned setting, when the operating mechanism is in the tripped state, by rotating the lever member 300 (specifically driven by a series of transmissions of the input shaft 400, the lever member 300, the first elastic member 214, and the first connecting rod assembly 210), the operating mechanism can be switched back to the open state, and can subsequently continue to switch between the open state and the closed state.

[0070] In this embodiment, a first stopper 140 is provided on the bracket 100, and the first stopper 140 is used to prevent the tripping member 200 from rotating further after the tripping member 200 rotates from the first tripping position to the second tripping position. Therefore, in the tripping state, the tripping member 200 can be stably maintained at the second tripping position under the pulling force of the first elastic member 214 and the abutting force of the first stopper 140.

[0071] In this embodiment, the bracket 100 is further provided with a second stopper 150, which is used to prevent the refastener 600 from continuing to rotate after the refastener 600 rotates from the release position to the abutment position. Correspondingly, a stopper 620 for abutting against the second stopper 150 is convexly provided on the shaft of the refastener 600. By providing the second stopper 150, the refastener 600 can be stably maintained at the abutment position under the elastic force of the third elastic member 630 and the abutment force of the second stopper 150, thereby stably abutting against the lock member 700.

[0072] The embodiment of the present application also provides an isolating switch (not shown in the figure), including a static contact assembly, a moving contact assembly and the operating mechanism provided in the above embodiment, the output shaft 500 is transmission connected to the moving contact assembly, when the rotating member 131 of the operating mechanism is in a first rotation position, the moving contact assembly is connected to the static contact assembly, when the rotating member 131 is in a second rotation position, the moving contact assembly is separated from the static contact assembly.

[0073] In summary, the present application provides an operating mechanism and an isolating switch. The operating mechanism includes a bracket 100 and an input shaft 400, an output shaft 500, a rotating member 131, a tripping member 200 and a lever member 300 rotatably connected to the bracket 100. The input shaft 400 is connected to the lever member 300 in a transmission manner to drive the lever member 300 to rotate. The tripping member 200 is connected to the rotating member 131 through a first connecting rod assembly 210. The first connecting rod assembly 210 is connected to the lever member 300 through a first elastic member 214. The rotating member 131 is connected to the output shaft 500 in a transmission manner to drive the output shaft 500 to rotate. The output shaft 500 is used to The operating mechanism has a closing state and an opening state. In the closing state and the opening state, the tripping member 200 is located at the first tripping position. In the closing state, the lever member 300 is in the first lever position, and the first connecting rod assembly 210 can drive the rotating member 131 to rotate to the first rotation position under the traction of the first elastic member 214. In the opening state, the lever member 300 is in the second lever position, and the first connecting rod assembly 210 drives the rotating member 131 to rotate to the second rotation position under the traction of the first elastic member 214. In the operating mechanism provided by the embodiment of the present application, the lever member 300 is driven to rotate between the first lever position and the second lever position by rotating the input shaft 400. When the lever member 300 is at the first lever position or the second lever position, the pulling direction of the first elastic member 214 is different, so the first connecting rod assembly 210 can be pulled into different postures, so that the rotating member 131 can be in the first rotation position or the second rotation position. Since the rotating member 131 can drive the output shaft 500 to rotate, the rotating member 131 in the first rotation position or the second rotation position can make the output shaft 500 in different rotation positions, thereby driving the external moving contact assembly to contact or separate from the static contact assembly, thereby achieving the connection and disconnection of the circuit (i.e., closing and opening). The operating mechanism provided by the embodiment of the present application is simple, stable, and has good reliability.

[0074] The isolating switch provided in the embodiment of the present application includes the above-mentioned operating mechanism, and therefore also has the advantages of good reliability and stability.

[0075] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application shall be based on the protection scope of the claims.
