Description

Technical Field

[0001] The present application relates to the technical field of electrical equipment, and particularly to an operating handle mechanism and a disconnecting switch. Background Art

[0002] A disconnecting switch is a switching device used to disconnect a circuit without load current and isolate the power supply. In the open state, a reliable insulation gap can be established to separate the equipment or line to be repaired from the power supply, ensuring the safety of maintenance personnel and equipment.

[0003] The disconnecting switch includes a handle body that can control its opening or closing. The user can control the disconnecting switch by rotating the handle body. However, after the user rotates the handle body to open the disconnecting switch, the handle body is prone to malfunction, which may lead to potential safety hazards. Summary of the Utility Model

[0004] The present application provides an operating handle mechanism and a disconnecting switch, which can reduce the possibility of malfunction of the handle body and thus reduce potential safety hazards.

[0005] In a first aspect, the present application provides an operating handle mechanism for use in a disconnecting switch. The operating handle mechanism includes a lock plate, a handle body, a lock core, and a connecting rod.

[0006] Among them, the handle body is supported on the lock plate and can rotate relative to the lock plate. A locking hole is provided on the side of the handle body facing the lock plate, and the handle body is used to cooperate with the disconnecting switch. The lock core is arranged in the locking hole and can slide in a direction close to or away from the lock plate. The connecting rod has a locking end and an operating end opposite to each other. The locking end cooperates with the lock core, and the part between the locking end and the operating end is rotatably connected to the handle body. The operating end is used to drive the connecting rod to rotate so that the lock core slides in the locking hole.

[0007] The lock core is locked with the lock plate after the handle body controls the disconnecting switch to open, so that the handle body is in a locked state.

[0008] In the embodiment of the present application, the connecting rod can drive the lock core to slide through the operating end. After the disconnecting switch is opened, the connecting rod can drive the lock core to slide to a position where it can be locked with the lock plate, so that the handle body can be fixed relative to the lock plate. At this time, the handle body is in a locked state, which can reduce the possibility that the handle body rotates after the disconnecting switch is opened, causing the disconnecting switch to close and connecting the circuit in an improper situation, resulting in potential safety hazards.

[0009] Optionally, the operating handle mechanism further includes a limiting structure, which is arranged on the handle body and the lock core, or the limiting structure is arranged on the lock core and the lock plate. The limiting structure is used to limit the lock core when the lock core is locked with the lock plate, so that the handle body remains in the locked state.

[0010] When the lock core and the lock disc are locked, the limiting structure can keep the lock core and the lock disc locked, reducing the possibility of easy separation after the lock core and the lock disc are locked, and thus the handle body can be kept in the locked state.

[0011] Optionally, when the limiting structure is arranged on the handle body and the lock core, the limiting structure includes a limiting protrusion and a limiting groove. The limiting protrusion is arranged on the inner wall of the locking hole, and the limiting groove is arranged on the lock core. When the handle body is in the locked state, the limiting protrusion is embedded in the limiting groove.

[0012] In this way, the limiting protrusion and the limiting groove can cooperate to keep the lock core and the lock disc in the locked state.

[0013] Optionally, when the limiting structure is arranged on the handle body and the lock core, the limiting structure includes a limiting boss and a limiting groove. The limiting boss is arranged on the surface of the lock core facing the inner wall of the locking hole, and the limiting groove is arranged on the inner wall of the locking hole. When the handle body is in the locked state, the limiting boss is embedded in the limiting groove.

[0014] In this way, the limiting boss and the limiting groove can cooperate to keep the lock core and the lock disc in the locked state.

[0015] Optionally, a locking hole is arranged on one side of the lock disc facing the handle body. When the limiting structure is arranged on the lock core and the lock disc, the limiting structure includes a limiting protrusion and a limiting card slot. The limiting protrusion is connected to the hole wall of the locking hole, and the limiting card slot is arranged on the lock core. When the handle body is in the locked state, the locking hole is opposite to the locking hole, a part of the lock core extends into the locking hole, and the limiting protrusion is embedded in the limiting card slot.

[0016] In this way, when the lock core slides in the direction close to the lock disc, one end of the lock core facing the lock disc can extend into the locking hole. The locking hole can limit the lock core, so that the lock core is fixed relative to the lock disc in the rotation direction of the handle body.

[0017] Moreover, the limiting protrusion and the limiting card slot can cooperate to keep the lock core and the lock disc in the locked state.

[0018] Optionally, the lock core includes a lock core body and a fitting connected to each other. The lock core body and the fitting are distributed along the axis direction of the locking hole. The lock core body is closer to the lock disc than the fitting. A fitting shaft is connected to the side of the fitting facing away from the lock core body. A fitting groove is arranged at the locking end. The fitting groove penetrates through the locking end along the axis direction of the fitting shaft, and the fitting shaft is embedded in the fitting groove. When the connecting rod rotates, the locking end can rotate relative to the fitting shaft, and the groove wall of the fitting groove can slide relative to the fitting shaft.

[0019] Thus, when the lock core slides relative to the lock disc, the lock core body can cooperate with the lock disc to lock, or the lock core body can be separated from the lock disc.

[0020] The cooperating part is located on the side away from the lock disc and can serve as the force-bearing part of the lock core, directly receive the force applied by the connecting rod, and drive the lock core body to slide in the locking hole.

[0021] Optionally, the operating handle mechanism further includes a lock handle and an assembly shaft. The lock handle is arranged on the side of the handle body facing away from the lock disc and is slidable relative to the handle body. The operating end is provided with an assembly groove that penetrates the operating end along the axis direction of the assembly shaft. The assembly shaft is inserted through the assembly groove and the lock handle. When the connecting rod rotates, the operating end can rotate relative to the assembly shaft, and the groove wall of the assembly groove can slide relative to the assembly shaft. The lock handle is used to apply force to the operating end through the assembly shaft so that the operating end drives the connecting rod to rotate.

[0022] With the above arrangement, the lock handle can be used as the driving part. When the lock handle slides relative to the handle body, the lock handle can drive the operating end to rotate relative to the assembly shaft, so that the locking end can drive the lock core to slide.

[0023] Optionally, an installation cavity is arranged on the side of the lock handle facing the handle body, and the lock handle is sleeved on a part of the handle body through the installation cavity. Guide blocks are arranged on the cavity wall of the installation cavity, and guide grooves are arranged on the handle body. The guide grooves extend along the axis direction of the locking hole. The guide blocks are embedded in the guide grooves and are slidable in the guide grooves.

[0024] Thus, during the process of the lock handle sliding relative to the handle body, the guide blocks can slide in the guide grooves. The arrangement of the guide blocks and the guide grooves can guide the sliding of the lock handle and reduce the possibility that the sliding of the lock handle deviates, resulting in the abnormal operation of the lock core.

[0025] Optionally, the operating handle mechanism further includes a limit block. The handle body includes a first main body and a second main body connected to each other. A sliding groove is arranged on the side of the first main body facing the lock handle. The lock handle has a movable part that is embedded in the sliding groove and is slidable relative to the sliding groove. A lock hole is arranged on the movable part. When the handle body is in the locked state, the part of the movable part with the lock hole extends out of the sliding groove, and the limit block is embedded in the lock hole and abuts against the second main body to keep the handle body in the locked state.

[0026] With the above arrangement, during the sliding process of the lock handle, the lock hole can be located inside the sliding groove or extend out of the sliding groove. When the lock hole extends out of the sliding groove, the limit block can be inserted into the lock hole. Thus, the sliding of the lock handle can be restricted by the limit block.

[0027] In a second aspect, the present application provides a disconnect switch, including any of the operating handle mechanisms in the first aspect above.

[0028] As provided in the second aspect described above and each possible design of the second aspect, the beneficial effects can be referred to the beneficial effects brought by the first aspect and each possible implementation manner of the first aspect, which will not be elaborated herein.

[0050] Exemplarily, an embodiment of the present application provides a disconnect switch, and the disconnect switch includes an operating handle mechanism 100 as Figure 1 shown.

[0051] The disconnect switch is a switching device used to ensure the safe isolation of a circuit. In the disconnect switch equipped with the above-mentioned operating handle mechanism 100, the disconnect switch can be opened or closed through the operating handle mechanism 100.

[0052] And when the disconnect switch is in the open state, the operating handle mechanism 100 can also keep the disconnect switch in the open state, making the disconnection of the disconnect switch from the circuit more reliable to ensure the safety of maintenance personnel and equipment.

[0053] In this application, the disconnect switch may further include a disconnect switch body. The operating handle mechanism 100 can be installed on the disconnect switch body, and the operating handle mechanism 100 can make the disconnect switch body act to realize the opening or closing of the disconnect switch.

[0054] The following will introduce the operating handle mechanism 100 provided by the embodiments of this application in detail with reference to the accompanying drawings.

[0055] As Figure 1 and Figure 2 shown, this application provides an operating handle mechanism 100, which is applied to a disconnect switch. The operating handle mechanism 100 includes a lock plate 10, a handle body 20, a lock core 30, and a connecting rod 40.

[0056] Among them, the handle body 20 is supported on the lock plate 10 and can rotate relative to the lock plate 10. A locking hole 21 is provided on the side of the handle body 20 facing the lock plate 10, and the handle body 20 is used to cooperate with the disconnect switch. The lock core 30 is arranged in the locking hole 21 and can slide in a direction close to or away from the lock plate 10. The connecting rod 40 has a relative locking end 41 and an operating end 42. The locking end 41 cooperates with the lock core 30, and the part between the locking end 41 and the operating end 42 is rotatably connected to the handle body 20. The operating end 42 is used to drive the connecting rod 40 to rotate so that the lock core 30 slides in the locking hole 21.

[0057] The lock core 30 is locked with the lock plate 10 after the handle body 20 controls the disconnect switch to open, so that the handle body 20 is in a locked state.

[0058] In the embodiments of this application, the operating handle mechanism 100 can cooperate with the disconnect switch body through the handle body 20. When the handle body 20 rotates relative to the lock plate 10, the handle body 20 can control the disconnect switch body to act, so as to open or close the disconnect switch to disconnect or connect the circuit.

[0059] A locking hole 21 is provided on the side of the handle body 20 facing the lock plate 10, and the lock core 30 can be arranged in the handle body 20 through the locking hole 21.

[0060] Among them, the lock core 30 can slide in a direction close to or away from the lock disc 10. Specifically, the lock core 30 can slide in a direction close to the lock disc 10 so that the lock core 30 can cooperate with the lock disc 10 for locking. Or, the lock core 30 can also slide in a direction away from the lock disc 10 so that the lock core 30 can be separated from the lock disc 10 and the locking with the lock disc 10 can be released.

[0061] The operating handle mechanism 100 further includes a connecting rod 40. The connecting rod 40 can be used as a driving part to provide power to the lock core 30 so that the lock core 30 slides in the locking hole 21.

[0062] Specifically, the connecting rod 40 includes a locking end 41 and an operating end 42. Among them, the locking end 41 can cooperate with the lock core 30, so that the connecting rod 40 can drive the lock core 30 to slide through the locking end 41.

[0063] The part between the locking end 41 and the operating end 42 is rotatably connected to the handle body 20. Since the locking end 41 and the operating end 42 are opposite to each other, the connecting rod 40 can form a structure similar to a lever, and the position where the connecting rod 40 is connected to the handle body 20 is the fulcrum of the lever. Thus, when the connecting rod 40 rotates under force, the movement trends of the locking end 41 and the operating end 42 are opposite.

[0064] Taking the operating handle mechanism 100 placed in the Figure 1 indicated orientation as an example. When the connecting rod 40 is subjected to a force that can make it rotate counterclockwise, the operating end 42 has a tendency to move upward, and the locking end 41 has a tendency to move downward. When the connecting rod 40 is subjected to a force that can make it rotate clockwise, the operating end 42 has a tendency to move downward, and the locking end 41 has a tendency to move upward.

[0065] Therefore, a force that can make it move away from the lock disc 10 can be applied to the operating end 42, so that the connecting rod 40 rotates counterclockwise. At this time, the locking end 41 can drive the lock core 30 to slide in a direction close to the lock disc 10, so that the lock core 30 can be locked with the lock disc 10 to make the handle body 20 in a locked state.

[0066] Or, a force that can make it move close to the lock disc 10 can be applied to the operating end 42, so that the connecting rod 40 rotates clockwise. At this time, the locking end 41 can drive the lock core 30 to slide in a direction away from the lock disc 10, so that the lock core 30 can be separated from the lock disc 10 and the locking of the handle body 20 can be released.

[0067] That is to say, in the embodiment of the present application, the connecting rod 40 can drive the lock core 30 to slide. After the disconnecting switch is opened, the connecting rod 40 can drive the lock core 30 to slide to a position where it can be locked with the lock plate 10, so that the handle body 20 can be fixed relative to the lock plate 10. At this time, the handle body 20 is in a locked state, which can reduce the possibility that after the disconnecting switch is opened, the handle body 20 rotates to cause the disconnecting switch to close, resulting in the disconnecting switch connecting the circuit under improper conditions and causing potential safety hazards.

[0068] Of course, after the disconnecting switch is closed, the connecting rod 40 can also drive the lock core 30 to slide to a position where it can be locked with the lock plate 10, so that the handle body 20 can be fixed relative to the lock plate 10. At this time, the handle body 20 is in a locked state, which can reduce the possibility that after the disconnecting switch is closed, the handle body 20 rotates to cause the disconnecting switch to open, resulting in the circuit being disconnected and the equipment stopping running.

[0069] It should be noted that when the operating handle mechanism 100 is installed on the disconnecting switch body, it can be that the handle body 20 is connected to the disconnecting switch body, and the handle body 20 can rotate relative to the disconnecting switch body.

[0070] Alternatively, it can also be that both the handle body 20 and the lock plate 10 are connected to the disconnecting switch body. At this time, the lock plate 10 can be fixed on the disconnecting switch body, and the handle body 20 can rotate relative to the disconnecting switch body.

[0071] It should also be noted that as Figure 2 shown, a first rotation hole 43 is provided between the locking end 41 and the operating end 42. As Figure 3 shown, a second rotation hole 26 is provided on the handle body 20. Thus, a rotating shaft 26 can be inserted between the first rotation hole 43 and the second rotation hole 26. As Figure 1 shown, the handle body 20 and the connecting rod 40 can be rotationally connected through the rotating shaft 26.

[0072] In some embodiments, as Figure 1 and Figure 4 shown, the operating handle mechanism 100 may further include a limiting structure 50. The limiting structure 50 is provided on the handle body 20 and the lock core 30, or the limiting structure 50 is provided on the lock core 30 and the lock plate 10. The limiting structure 50 is used to limit the lock core 30 when the lock core 30 and the lock plate 10 are locked, so as to keep the handle body 20 in a locked state.

[0073] When the lock core 30 and the lock plate 10 are locked, the limiting structure 50 can keep the lock core 30 and the lock plate 10 locked, reducing the possibility of the lock core 30 and the lock plate 10 being easily separated after being locked, and further keeping the handle body 20 in a locked state.

[0074] In the embodiments of the present application, the limiting structure 50 is provided on the handle body 20 and the lock core 30, or the limiting structure 50 is provided on the lock core 30 and the lock plate 10. That is, the limiting structure 50 can have multiple setting methods, and the following three are taken as examples for specific illustration:

[0075] Method 1: When the limiting structure 50 is provided on the handle body 20 and the lock core 30, the limiting structure 50 includes a limiting protrusion 51 and a limiting groove 52, as Figure 1 and Figure 4 shown. The limiting protrusion 51 is provided on the inner wall of the locking hole 21, and the limiting groove 52 is provided on the lock core 30. When the handle body 20 is in the locked state, the limiting protrusion 51 is embedded in the limiting groove 52.

[0076] In this way, the limiting protrusion 51 and the limiting groove 52 can cooperate to keep the lock core 30 and the lock plate 10 in the locked state.

[0077] When the lock core 30 slides in the locking hole 21, the relative position between the limiting groove 52 and the limiting protrusion 51 will also change. When the lock core 30 and the lock plate 10 are locked, the limiting protrusion 51 can be opposite to the limiting groove 52, and the two cooperate with each other.

[0078] Thus, the limiting protrusion 51 can limit the limiting groove 52, so that the position of the limiting groove 52 on the lock core 30 is fixed relative to the limiting protrusion 51, so as to keep the lock core 30 in the locked position with the lock plate 10.

[0079] Method 2: When the limiting structure 50 is provided on the handle body 20 and the lock core 30, the limiting structure 50 includes a limiting boss and a limiting groove. The limiting boss is provided on the surface of the lock core 30 facing the inner wall of the locking hole 21, and the limiting groove is provided on the inner wall of the locking hole 21. When the handle body 20 is in the locked state, the limiting boss is embedded in the limiting groove.

[0080] In this way, the limiting boss and the limiting groove can cooperate to keep the lock core 30 and the lock plate 10 in the locked state.

[0081] When the lock core 30 slides in the locking hole 21, the relative position between the limiting boss and the limiting groove will also change. When the lock core 30 and the lock plate 10 are locked, the limiting boss can be opposite to the limiting groove, and the two cooperate with each other.

[0082] Thus, the limiting groove can limit the limiting boss, reducing the possibility of the limiting boss sliding relative to the limiting groove, so as to keep the lock core 30 in the locked position with the lock plate 10.

[0083] Method 3: As Figure 1 、 Figure 4 and Figure 5As shown in the figure, a locking hole 11 is provided on one side of the lock plate 10 facing the handle body 20. When the limiting structure 50 is arranged between the lock core 30 and the lock plate 10, the limiting structure 50 includes a limiting protrusion and a limiting groove. The limiting protrusion is connected to the inner wall of the locking hole 11, and the limiting groove is arranged on the lock core 30. When the handle body 20 is in the locked state, the locking hole 11 is opposite to the locking stop hole 21, a part of the lock core 30 extends into the locking hole 11, and the limiting protrusion is embedded in the limiting groove.

[0084] In this way, when the lock core 30 slides in the direction close to the lock plate 10, one end of the lock core 30 facing the lock plate 10 can extend into the locking hole 11. The locking hole 11 can limit the lock core 30, so that the lock core 30 is fixed relative to the lock plate 10 in the rotation direction of the handle body 20.

[0085] Since the lock core 30 is arranged on the handle body 20, the handle body 20 can also be fixed relative to each other in its rotation direction, reducing the possibility of misoperation of the disconnecting switch caused by the rotation of the handle body 20.

[0086] When the locking hole 11 is provided on the lock plate 10, the limiting structure 50 may include a limiting protrusion and a limiting groove. The limiting protrusion and the limiting groove can cooperate to keep the lock core 30 and the lock plate 10 in the locked state.

[0087] Specifically, the limiting protrusion can be arranged on the inner wall of the locking hole 11, and the limiting groove can be arranged on the lock core 30.

[0088] When the lock core 30 slides in the locking stop hole 21, the relative position between the limiting protrusion and the limiting groove also changes. When the lock core 30 is locked with the lock plate 10, the limiting groove can be opposite to the limiting protrusion, and the two cooperate with each other.

[0089] Thus, the limiting protrusion can limit the limiting groove, so that the position of the limiting groove provided on the lock core 30 is fixed relative to the limiting protrusion, so that the lock core 30 is kept in the locked position with the lock plate 10.

[0090] In the embodiment of the present application, the lock core 30 extends into the locking hole 11 on the lock plate 10. At this time, the inner wall of the locking hole 11 can limit the rotation of the lock core 30. Since the lock core 30 is installed on the handle body 20, while the inner wall of the locking hole 11 limits the rotation of the lock core 30, the rotation of the handle body 20 can also be restricted. In addition to the above settings, the lock core 30 and the lock plate 10 can also restrict the rotation of the handle body 20 in other ways.

[0091] For example, when the lock core 30 is locked with the lock plate 10, the surfaces of the lock core 30 and the lock plate 10 facing the handle body 20 can be fitted by friction. The large frictional force between the lock core 30 and the lock plate 10 can also fix the lock core 30 relative to the lock plate 10, playing a role in restricting the rotation of the handle body 20.

[0092] It should be noted that when the locking hole 11 is provided on the lock plate 10, the locking of the lock core 30 and the lock plate 10 is not limited to being maintained by the cooperation of the limiting convex block and the limiting card slot. The locking of the lock core 30 and the lock plate 10 can also be maintained by the setting of the limiting structure 50 in Method 1 or Method 2.

[0093] Of course, in order to achieve a better locking effect between the lock core 30 and the lock plate 10, Method 3 can also be combined with Method 1 or Method 2.

[0094] In some embodiments, as Figure 1 and Figure 6 shown, the lock core 30 may include a lock core body 31 and a fitting 32 connected to each other. The lock core body 31 and the fitting 32 are distributed along the axis direction of the locking hole 21, and the lock core body 31 is closer to the lock plate 10 than the fitting 32.

[0095] In this way, when the lock core 30 slides relative to the lock plate 10, the lock core body 31 can be fitted and locked with the lock plate 10, or the lock core body 31 can be separated from the lock plate 10.

[0096] The fitting 32 is located on the side away from the lock plate 10 and can serve as the force-receiving part of the lock core 30, directly receiving the force applied by the connecting rod 40 and driving the lock core body 31 to slide in the locking hole 21.

[0097] When the lock core 30 includes the lock core body 31 and the fitting 32, the locking end 41 and the fitting 32 can be specifically fitted through the following structure.

[0098] As Figure 1 、 Figure 2 and Figure 6 shown, a fitting shaft 33 may be connected to the side of the fitting 32 facing away from the lock core body 31. The locking end 41 is provided with a fitting groove 411, and the fitting groove 411 penetrates through the locking end 41 along the axis direction of the fitting shaft 33. The fitting shaft 33 is embedded in the fitting groove 411. When the connecting rod 40 rotates, the locking end 41 can rotate relative to the fitting shaft 33, and the groove wall of the fitting groove 411 can slide relative to the fitting shaft 33.

[0099] With the above settings, the mating shaft 33 on the lock core 30 can be inserted through the notch of the mating groove 411 into the locking end 41. When the connecting rod 40 rotates, the locking end 41 can rotate relative to the mating shaft 33, increasing or decreasing the distance between the locking end 41 and the lock disc 10. Thus, the locking end 41 can apply a force to the mating member 32, causing the distance between the lock core 30 and the lock disc 10 to also increase or decrease.

[0100] Meanwhile, during the above process, since the sliding direction of the lock core 30 is along the axis direction of the locking hole 21, the mating shaft 33 cannot rotate relative to the rotating shaft 26 along with the locking end 41. During the rotation of the connecting rod 40, the groove wall of the mating groove 411 can slide relative to the mating shaft 33, changing the contact position between the locking end 41 and the mating shaft 33.

[0101] It should be noted that, as Figure 1 and Figure 6 shown, a bearing groove 34 can be provided on the side of the mating member 32 facing away from the lock core body 31, and the mating shaft 33 can be arranged in the bearing groove 34, and both ends of the mating shaft 33 are connected to the groove wall of the bearing groove 34.

[0102] Meanwhile, as Figure 1 、 Figure 2 and Figure 6 shown, the locking end 41 can keep in contact with the bottom of the bearing groove 34. Thus, when the connecting rod 40 rotates, the locking end 41 can also slide relative to the bottom of the bearing groove 34. When the distance between the locking end 41 and the lock disc 10 decreases, the locking end 41 can directly push the bottom of the bearing groove 34 in the direction close to the lock disc 10, and further cause the lock core body 31 to slide in the direction close to the lock disc 10.

[0103] That is, in this embodiment, the locking end 41 can apply a force to the mating member 32 through the bottom of the bearing groove 34, making the driving of the locking end 41 on the lock core 30 more reliable.

[0104] Taking the operating handle mechanism 100 placed in the orientation as shown in Figure 1 as an example, Figure 1 the vertically downward direction in

[0105] is the gravity direction. At this time, the locking end 41 may not be in contact with the bottom of the bearing groove 34 either. When the connecting rod 40 rotates counterclockwise, the operating end 42 is separated from the assembly shaft 61, and the lock core 30 can also slide in the direction close to the lock disc 10 under the action of gravity.

[0106] It should also be noted that when the operating handle mechanism 100 is placed in the orientation shown, the first rotation hole 43 can be provided on the side close to the locking end 41, so that the center of gravity of the connecting rod 40 falls between the first rotation hole 43 and the operating end 42. Moreover, in the mechanism formed by the lock core 30 and the connecting rod 40, the center of gravity of the mechanism can also be located on the side close to the operating end 42. As shown Figure 1 Figure 2 as follows.

[0107] At this time, if it is necessary to release the locking of the handle body 20, the cooperation of the limiting structure 50 can be disconnected. After that, the connecting rod 40 can rotate clockwise under the action of its own gravity, so that the lock core 30 can slide in the direction away from the lock disc 10 and separate from the lock disc 10.

[0108] As Figure 1 , Figure 2 and Figure 7 shown, the operating handle mechanism 100 may further include a lock handle 60 and a fitting shaft 61. The lock handle 60 is provided on the side of the handle body 20 facing away from the lock disc 10 and is slidable relative to the handle body 20. The lock handle 60 is used to apply a force to the operating end 42 through the fitting shaft 61, so that the operating end 42 drives the connecting rod 40 to rotate.

[0109] In this embodiment, the lock handle 60 can be used as the active part. When the lock handle 60 slides relative to the handle body 20, the lock handle 60 can drive the operating end 42 of the connecting rod 40 to rotate relative to the fitting shaft 61, so that the locking end 41 can drive the lock core 30 to slide.

[0110] The connecting rod 40 and the lock handle 60 can be cooperated through the fitting shaft 61, so that when the locking slides, the connecting rod 40 can rotate.

[0111] Specifically, as Figure 1 , Figure 2 and Figure 7 shown, the operating end 42 is provided with a fitting groove 421. The fitting groove 421 penetrates the operating end 42 along the axis direction of the fitting shaft 61. The fitting shaft 61 passes through the fitting groove 421 and the lock handle 60. When the connecting rod 40 rotates, the operating end 42 can rotate relative to the fitting shaft 61, and the groove wall of the fitting groove 421 can slide relative to the fitting shaft 61.

[0112] Through the above settings, the fitting shaft 61 can pass through the operating end 42 and the lock handle 60 at the same time. At the operating end 42, the fitting shaft 61 can pass through the notch of the fitting groove 421. When the lock handle 60 slides, the lock handle 60 can directly drive the fitting shaft 61 to slide.

[0113] ​Since the assembly shaft 61 is disposed in the assembly groove 421, the lock handle 60 actually drives the operating end 42 to slide via the assembly shaft 61. Since the connecting rod 40 is rotatably connected to the handle body 20, for the connecting rod 40 as a whole, the operating end 42 actually rotates relative to the rotating shaft 26, thereby realizing the rotation of the connecting rod 40.

[0114] At the same time, in the above process, the handle body 20 can limit the sliding direction of the lock handle 60, and the assembly shaft 61 is disposed in the lock handle 60, so in fact, the sliding direction of the assembly shaft 61 is also limited by the handle body 20. During the rotation of the connecting rod 40, the assembly shaft 61 slides along the groove wall of the assembly groove 421 under the action of the handle body 20 and the assembly groove 421, so that the contact position between the operating end 42 and the assembly shaft 61 changes.

[0115] It should be noted that, when the lock handle 60 is provided, the user can apply force to the connecting rod 40 through the lock handle 60. This can reduce the possibility of the problem that the connecting rod 40 has a small operating space and is inconvenient to apply force, resulting in greater operating difficulty.

[0116] In order to facilitate the user to apply force to the lock handle 60, a fixed handle or a rotatable handle 66 or the like may be installed on the lock handle 60. Thus, the user can apply force to the lock handle 60 through the handle or the handle 66, which is convenient for the user to operate. Figure 7 , Figure 8 as well as Figure 9 shown.

[0117] In the operating handle mechanism 100 Figure 1 When the handle body 20 is placed in the position shown, if the handle body 20 is to be unlocked, the stop structure 50 can be disconnected. Then, the lock handle 60 can apply force to the connecting rod 40 under the action of its own gravity, so that the connecting rod 40 can drive the lock core 30 to slide in a direction away from the lock disk 10 and separate from the lock disk 10.

[0118] It should also be noted that the operating end 42 can maintain contact with the side of the lock handle 60 facing the lock disk 10. Therefore, when the lock handle 60 slides, the operating end 42 can also slide along the side of the lock handle 60 facing the lock disk 10. The lock handle 60 can directly apply force to the operating end 42 to drive the connecting rod 40 to rotate, which can make the lock handle 60 drive the connecting rod 40 more reliably.

[0119] Furthermore, when the operating end 42 and the lock handle 60 are kept in contact, the lock handle 60 can be prevented from being separated from the operating member. The lock handle 60 has to perform an idle stroke before applying force to the connecting rod 40, so that the connecting rod 40 reacts more sensitively.

[0120] In order to make the structure and principle of this embodiment clearer, the following analysis is performed in conjunction with the motion diagram of the operating handle mechanism 100:

[0121] As Figure 5 shown, in the operating handle mechanism 100, there are three movable parts: the lock cylinder 30, the connecting rod 40, and the lock handle 60. There are three lower pairs and two higher pairs.

[0122] Among them, the lower pair restricts two degrees of freedom, and the higher pair restricts one degree of freedom.

[0123] The three lower pairs are respectively the sliding pair between the lock cylinder 30 and the locking hole 21, the sliding pair between the lock handle 60 and the handle body 20, and the rotating pair between the connecting rod 40 and the handle body 20. The two higher pairs are the line contact between the locking end 41 and the mating shaft 33, and the line contact between the operating end 42 and the fitting shaft 61.

[0124] According to the number of degrees of freedom that the lower pair and the higher pair can restrict, the theoretical degree of freedom of the operating handle mechanism is calculated. The theoretical degree of freedom F = 3×3 - 3×2 - 2×1 = 1. It can be seen that when a force is applied to the lock handle 60, the lock cylinder 30 can slide in the locking hole 21.

[0125] In some embodiments, as Figure 7 , Figure 8 and Figure 9 shown, on one side of the lock handle 60 facing the handle body 20, an installation cavity 62 can be provided. The lock handle 60 is sleeved on a part of the handle body 20 through the installation cavity 62. A guiding block 63 is provided on the cavity wall of the installation cavity 62, and a guiding groove 22 is provided on the handle body 20. The guiding groove 22 extends along the axis direction of the locking hole 21. The guiding block 63 is embedded in the guiding groove 22 and can slide in the guiding groove 22.

[0126] In this way, during the process of the lock handle 60 sliding relative to the handle body 20, the guiding block 63 can slide in the guiding groove 22. The arrangement of the guiding block 63 and the guiding groove 22 can guide the sliding of the lock handle 60, reducing the possibility that the sliding of the lock handle 60 deviates, resulting in the abnormal operation of the lock cylinder 30.

[0127] In addition, in the embodiments of the present application, on the side of the guiding groove 22 away from the lock plate 10, the handle body 20 may not be penetrated. Thus, the guiding groove 22 can have an abutting wall facing the lock plate 10. During the process of the lock handle 60 moving in the direction away from the lock plate 10, the guiding block 63 can abut against the abutting wall to limit the movement of the guiding block 63.

[0128] That is, the arrangement of the abutting wall can limit the movement of the guiding block 63, and further limit the movement of the lock handle 60. It can reduce the possibility of the problem that the lock handle 60 detaches from the handle body 20 when sliding in the direction away from the lock plate 10.

[0129] When the operating handle mechanism 100 includes the locking disk 10, in addition to the above-mentioned limiting structure 50, the present application can also maintain the positions of the lock core 30 and the locking disk 10 in other ways when the lock core 30 and the locking disk 10 are locked. For details, please refer to the following embodiments.

[0130] As Figure 3 and Figures 7 to 9 shown, the handle body 20 includes a first main body 23 and a second main body 24 that are connected to each other. A chute 25 is provided on one side of the first main body 23 facing the lock handle 60. The lock handle 60 has a movable part 64, and the movable part 64 is embedded in the chute 25 and can slide relative to the chute 25.

[0131] Through the above settings, the movable part 64 can cooperate with the chute 25 to realize the sliding connection between the handle body 20 and the lock handle 60. When the lock handle 60 slides relative to the handle body 20, the movable part 64 can slide in the chute 25.

[0132] When the movable part 64 slides relative to the chute 25, a part of the movable part 64 provided with the lock hole 65 can slide in the chute 25 or protrude from the chute 25.

[0133] Among them, the operating handle mechanism 100 can also include a limiting block. A lock hole 65 is provided on the movable part 64. When the handle body 20 is in the locked state, a part of the movable part 64 provided with the lock hole 65 protrudes from the chute 25, and the limiting block is embedded in the lock hole 65 and abuts against the second main body 24 to keep the handle body 20 in the locked state.

[0134] That is, during the sliding process of the lock handle 60, the lock hole 65 can be located inside the chute 25 or protrude from the chute 25. When the lock hole 65 protrudes from the chute 25, the limiting block can be inserted into the lock hole 65.

[0135] Since the limiting block has a part that abuts against the second main body 24, the limiting block can block a part of the movable part 64 provided with the lock hole 65 from sliding in the direction close to the locking disk 10. That is, in the direction from the handle body 20 to the locking disk 10, the limiting block can limit the sliding of the lock handle 60. Thereby, the possibility of the lock core 30 and the locking disk 10 being separated due to the lock handle 60 moving towards the side close to the locking disk 10 can be reduced, ensuring the locking of the lock core 30 and the locking disk 10.

[0136] Among them, the limiting block can be adapted to the lock hole 65. Specifically, in the axial direction of the lock hole 65, the projection of the limiting block can be the same in shape and size as the projection of the inner wall of the lock hole 65. Thereby, the limiting block can be embedded in the lock hole 65, and the possibility of the problem that the limiting block is easily separated from the lock hole 65 when the limiting block is too small can be avoided.

[0137] It should be noted that the number of keyholes 65 can be set to multiple, such as Figure 8 and Figure 9 as shown. Correspondingly, multiple limit blocks can be set, and the multiple limit blocks can be respectively arranged in the multiple keyholes 65 and abut against different positions of the second body 24 to improve the effect of the limit blocks.

[0138] Among them, the number of the keyholes 65 and the limit blocks can both be 2, 3, 4 or 5, etc. Of course, the number of the keyholes 65 and the limit blocks can also both be 1. The specific number of the keyholes 65 and the limit blocks is not specifically limited in the embodiments of the present application.

[0139] It should also be noted that in the present application, only one of the limit block and the limiting structure 50 can be applied, or the limit block and the limiting structure 50 can also be applied simultaneously. In this regard, the embodiments of the present application do not make specific limitations either.

[0140] In some embodiments, as Figure 10 shown, the assembly shaft 61 has a first assembly portion 611 and a second assembly portion 612 that are connected to each other. In the axial direction of the assembly shaft 61, the projection of the first assembly portion 611 is located inside the projection of the second assembly portion 612. Thus, the assembly shaft 61 can present a stepped structure, and the size of the first assembly portion 611 is smaller.

[0141] As Figures 8 to 10 shown, in the axial direction of the assembly shaft 61, the lock handle 60 has an opposite first surface 601 and a second surface 602. The first surface 601 is provided with a first assembly hole 67, and the second surface 602 is provided with a second assembly hole 68. The first assembly portion 611 passes through the first assembly hole 67, and the second assembly portion 612 passes through the second assembly hole 68, and the side of the second assembly portion 612 facing the first assembly portion 611 abuts against the cavity wall of the installation cavity 62.

[0142] Among them, the first assembly portion 611 passes through the first assembly hole 67, and the second assembly portion 612 passes through the second assembly hole 68. Since the size of the first assembly portion 611 is smaller and the size of the second assembly portion 612 is larger, the size of the first assembly hole 67 is also smaller, and the size of the second assembly hole 68 is larger.

[0143] In this way, at the first surface 601, since the size of the first assembly hole 67 is smaller, the second assembly portion 612 cannot pass through the first assembly hole 67. The assembly shaft 61 can be limited in the direction from the second surface 602 to the first surface 601. Furthermore, the possibility of the problem that the movement of the assembly shaft 61 in the direction from the second surface 602 to the first surface 601 affects the connection between the handle body 20, the lock handle 60, and the connecting rod 40 can be reduced.

[0144] Similarly, the assembly shaft 61 can also be limited in the direction from the first surface 601 to the second surface 602, so as to reduce the possibility that the movement of the assembly shaft 61 in the direction from the first surface 601 to the second surface 602 affects the connection between the handle body 20, the locking handle 60 and the connecting rod 40.

[0145] Specifically, a part of the second assembly portion 612 can extend from the second surface 602. At this time, a blocking member can be connected to the side of the second assembly portion 612 away from the first assembly portion 611, and the blocking member is in contact with the second surface 602. Alternatively, the extended part of the second assembly portion 612 can be thickened so that the size of the thickened part of the second assembly portion 612 is larger than the second assembly hole 68, and the thickened part of the second assembly portion 612 can achieve the limiting function.

[0146] In the embodiment of the present application, the connecting rod 40 can drive the lock core 30 to slide through the operating end 42. After the disconnector is switched off, the connecting rod 40 can drive the lock core 30 to slide to a position where it can be locked with the lock plate 10, so that the handle body 20 can be fixed relative to the lock plate 10. At this time, the handle body 20 is in the locked state, which can reduce the possibility that after the disconnector is switched off, the handle body 20 rotates to cause the disconnector to switch on, resulting in the disconnector connecting the circuit under improper conditions and causing potential safety hazards.

[0147] Finally, it should be noted that the above embodiments are only specific embodiments of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions within the technical scope disclosed in the present application should be covered by the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
