Description

Technical Field

[0001] The utility model relates to the technical field of electricity, and particularly relates to an operating mechanism and a disconnector. Background Art

[0002] For the operating mechanism of the original disconnector, there is also a link mechanism in the form of a molded case circuit breaker to realize the opening and closing functions. However, a complex transmission structure is still required between the input shaft and the lever to achieve the force conversion. Such a driving force is not direct enough, so the structure is not very ideal. Content of the Utility Model

[0003] Therefore, the technical problem to be solved by the utility model is how to realize the cooperation between the input shaft and the lever. For this purpose, an operating mechanism includes: a first linkage shaft, a lever, a first transmission unit and a locking component. The lever is connected to the first linkage shaft and the first transmission unit.

[0004] The rotation axis of the first linkage shaft and the rotation axis of the lever are coaxially arranged, and the first linkage shaft and the lever are synchronously rotated.

[0005] The first transmission unit includes a link assembly, an output assembly, a toggle and an elastic component. The toggle is rotatably connected to the lever. One end of the link assembly is rotatably connected to the toggle, and the other end of the link assembly is connected to the output assembly. An elastic component is connected between a joint position of the link assembly and the lever. The output assembly is rotatably arranged and drives the moving contact disk of the disconnector to rotate under the action of the link assembly to realize opening and closing.

[0006] The locking component is used for locking and unlocking the toggle.

[0007] The lever is of a U-shaped structure, and the first linkage shaft is connected to one side arm of the lever.

[0008] Or, the lever is of a U-shaped structure, the first linkage shaft is linked with the lever, and the first linkage shaft penetrates through the two side arms of the lever.

[0009] Or, the rotation axis of the first linkage shaft and the rotation axis of the output assembly are coaxially arranged.

[0010] Or, the rotation axis of the first linkage shaft and the rotation axis of the output assembly are non-coaxially arranged.

[0011] It further includes a knob and a second transmission unit. The knob is rotatably arranged, and the total rotation stroke of the knob is a first angle, while the total rotation stroke of the first linkage shaft is a second angle, and the first angle is greater than the second angle. The second transmission unit is connected between the knob and the first linkage shaft, and the knob and the lever with different total strokes are transmitted through the second transmission unit.

[0012] The second transmission unit includes a linkage assembly and an energy storage assembly. One end of the linkage assembly is arranged to rotate synchronously with the knob. The linkage assembly is provided with a first cavity, and the first linkage shaft penetrates into the first cavity. There is an idle stroke between the first cavity and the first linkage shaft. After the relative rotation between the first cavity and the first linkage shaft eliminates the idle stroke, the two come into contact to achieve a driving connection. The linkage assembly is provided with a driving part. The energy storage assembly cooperates with the driving part. During the process of driving the knob to rotate the lever, the energy storage assembly first stores energy and then releases energy to provide a driving force for the rotation of the linkage assembly, and the energy storage of the energy storage assembly is completed before the idle stroke is eliminated.

[0013] The first linkage shaft includes a first acting surface and a second acting surface that are arranged at an obtuse angle to each other. The first cavity is provided with a first plane. After the first plane comes into contact with the first acting surface or comes into contact with the second acting surface, the two form a driving connection. The idle stroke means the angle of relative rotation between the linkage assembly and the first linkage shaft before the first plane reaches the contact with the first acting surface or the second acting surface.

[0014] The linkage assembly includes a second linkage shaft and a linkage member. The second linkage shaft and the linkage member are arranged to move synchronously. The first cavity is opened at one end of the second linkage shaft facing the lever. The other end of the second linkage shaft is linked with the knob, and the driving part is arranged on the linkage member.

[0015] It further includes a bracket. The energy storage assembly includes a sliding member and an elastic member. The sliding member slides relative to the bracket. One end of the elastic member is connected to the sliding member, and the other end of the elastic member is directly or indirectly connected to the bracket. The sliding member has a raised portion. During the rotation of the linkage assembly, the driving part moves along the raised portion. Before reaching the highest point of the raised portion, the elastic member stores energy, and after passing over the highest point of the raised portion, the elastic member releases energy. When the driving part reaches the highest point of the raised portion, the wall of the first cavity and the first linkage shaft have not yet come into contact.

[0016] The second transmission unit includes a planetary gear module, which includes a sun gear, a ring gear, a planet carrier and a planetary gear. The planetary gear is located between the sun gear and the ring gear. The sun gear is meshed with the planetary gear, and the planetary gear is meshed with the ring gear. The planetary gear is rotatable, and the rotation of the planetary gear includes both rotation about its own first axis and revolution about its second axis. The planetary carrier is fixed to the planetary gear and is rotatable about the second axis.

[0017] The gear ring is fixed, the sun gear is rotatably arranged, the sun gear is drivingly connected to the knob, the planet carrier is drivingly connected to the lever, and the sun gear rotates to drive the planet gear and the planet carrier to rotate;

[0018] Or, the gear ring is fixed, the planet carrier is in driving connection with the knob, the sun gear is in driving connection with the lever, and the planet carrier rotates so that the planet gear drives the sun gear to rotate;

[0019] Or, the sun gear is fixed, the ring gear is rotating, the ring gear is drivingly connected to the knob, the planet carrier is drivingly connected to the lever, and the ring gear is rotating to drive the planet gear and the planet carrier to rotate;

[0020] Alternatively, the sun gear is fixed, the ring gear is rotating, the planet carrier is transmission connected to the knob, the ring gear is transmission connected to the lever, and the planet carrier rotates so that the planet gear drives the ring gear to rotate.

[0021] Therefore, the technical problem to be solved by the utility model is how to achieve the problem of matching the input shaft with the lever. To this end, an isolating switch includes an operating unit layer and a switch unit layer; the switch unit layer is at least two layers, which are stacked in sequence below the operating unit layer, and the switch unit layer close to the operating unit layer is the first switch unit layer; the operating unit layer includes a body, a cover plate, and the above-mentioned operating mechanism; the output component is linked with the moving contact plate of the first switch unit layer.

[0022] The technical solution of the utility model has the following advantages:

[0023] 1. The utility model provides an operating mechanism, which directly adopts a first linkage shaft and a lever to rotate synchronously, and the rotation centers between the two are the same. The force from the first linkage shaft can directly drive the lever to rotate, which has a direct driving force effect.

[0024] 2. An operating mechanism provided by the present utility model. With this structure, the first linkage shaft and the lever can form a linkage effect of a single-side arm, and the first linkage shaft can also adopt a penetrating method to form a linkage effect of a double-side arm, improving the linkage effect of the lever; the rotational axes of the first linkage shaft and the output assembly can be coaxial or non-coaxial.

[0025] 3. An operating mechanism provided by the present utility model. With this structure, the second transmission unit converts the angle so that the rotation angle of the knob matches the opening and closing angles of the lever.

[0026] 4. An operating mechanism provided by the present utility model. Through the idle stroke, the extra rotation angle is consumed during the rotation process to match the rotation angle of the knob with the opening and closing angles of the lever, thus meeting the rotation effect of the lever; during the entire movement process, the energy storage component forms an energy storage and energy release effect, which can help with the rotation effect and achieve the reduction of the reclosing force and closing force; during the operation process of the entire operating mechanism, for example, when the knob rotates 90°, through the idle stroke, the rotation angle of the first linkage shaft matches the opening and closing angles of the lever. Here, the rotation angle of the lever is a small angle, and the rotation of the lever realizes the rotation of the first transmission unit. Through the cooperation of the connecting rod assembly and the elastic component, the rotation angle is amplified, so that the rotation angle of the output assembly matches the opening and closing angles of the moving contact disc. Here, the opening and closing angles of the moving contact disc are 90°. Thus, the opening and closing operations of the entire operating mechanism are realized.

[0027] 5. An operating mechanism provided by the present utility model. The cooperation between the first plane and the first acting surface and the second acting surface forms the effect of the idle stroke. In addition, the cooperation of the shaft and the waist-shaped hole can also form an idle stroke effect, that is, the distance from one end of the waist-shaped hole to the other end of the waist-shaped hole when the shaft moves is the idle stroke.

[0028] 6. An operating mechanism provided by the present utility model. The cooperation between the second linkage shaft and the linkage part better realizes the linkage effect.

[0029] 7. An operating mechanism provided by the present utility model. The mutual cooperation among the sliding part, the elastic part, and the linkage part forms the cooperation effect between the first linkage shaft and the first cavity during the rotation process. The elastic part plays an energy storage and energy release effect. The elastic part plays an energy storage effect. When crossing the critical point, the elastic part will quickly release energy to accelerate the rotation (most importantly, energy storage is completed during the idle rotation, which can provide spring force in the non-idle rotation state, reduce the manual operation force, and make the feel better).

[0030] 8. An operating mechanism provided by the present utility model realizes the amplification of torque through the setting of a planetary gear module, and utilizes the transmission ratio to match the rotation angle of the knob with the opening and closing angles of the lever, thereby satisfying the rotation effect of the lever. Secondly, by setting the output end of the planetary gear module (i.e., the output end of the second transmission unit) and the rotation axis of the lever to be coaxial, the assembly is more streamlined. Compared with the non-coaxial setting of the output end of the planetary gear module and the rotation axis of the lever, different positioning and installation are required between the lever and the planetary gear module, and a transmission component is also required for transmission, resulting in a complex overall structure and cumbersome assembly. The structure of this application has a streamlined effect and improves the assembly efficiency. Finally, the planetary gear module is modularly set, which is convenient for installation and can achieve the effect of rapid assembly.

[0031] 9. For an operating mechanism provided by the present utility model, the specific meaning that the ring gear is fixed is that when the knob rotates, the ring gear is in a stationary state and does not move. At this time, the knob is linked with the sun gear, and the knob drives the sun gear to rotate. The sun gear cooperates with the planet gears to drive the planet carrier to move. At this time, the planet carrier drives the lever to rotate, thereby realizing the opening and closing operations of the lever. Or, the knob is linked with the planet carrier, the knob drives the planet carrier to rotate, the planet carrier is linked with the planet gears, the planet gears drive the sun gear to move, and the sun gear drives the lever to rotate. The difference between this scheme and the above scheme is the different cooperation positions between the lever and the planetary gear module. The specific meaning that the sun gear is fixed is that when the knob rotates, the sun gear is in a stationary state and does not move. At this time, the knob is linked with the ring gear, the knob drives the ring gear to rotate, the ring gear cooperates with the planet gears to drive the planet carrier to move. At this time, the planet carrier drives the lever to rotate, thereby realizing the opening and closing operations of the lever. Or, the knob is linked with the planet carrier, the knob drives the planet carrier to rotate, the planet carrier is linked with the planet gears, the planet gears drive the ring gear to move, and the ring gear drives the lever to rotate. The difference between this scheme and the above scheme is the different cooperation positions of the lever.

[0032] 10. For an isolating switch provided by the present utility model, the operating mechanism is arranged on the operating unit layer, and the output component is linked with the moving contact disk of the first-layer switch unit layer to form the driving effect of the entire isolating switch.

[0063] In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0064] Embodiment 1

[0065] This embodiment provides an operating mechanism. As shown in the attached Figures 1 - 10 figure, it includes a first linkage shaft 18, a lever 12, a first transmission unit 102, and a locking assembly. The lever 12 is connected to a second transmission unit 101 and a first transmission unit 102.

[0066] The rotation axis of the first linkage shaft 18 and the rotation axis of the lever 12 are arranged coaxially. The first linkage shaft 18 and the lever 12 are synchronously rotated, that is, when the first linkage shaft 18 rotates, it drives the lever 12 to rotate together.

[0067] The first drive unit 102, the first drive unit 102 includes a link assembly 21, an output assembly 26, a jump latch 19 and an elastic assembly. Here, the link assembly 21 includes an upper link and a lower link (the joint position is the hinged position of the two), and in addition, it can also be a three-link, or other link structures. The jump latch 19 is rotatably connected to the lever 12, and the lever 12 drives the jump latch 19 to rotate. One end of the link assembly 21 is also rotatably connected to the jump latch 19, and the other end of the connecting assembly is in transmission cooperation with the output assembly 26, realizing the effect that the link assembly 21 drives the output assembly 26 to rotate. The joint position of the link assembly 21 and the lever 12 are connected by an elastic assembly. The elastic assembly (that is, the main tension spring) is used to realize the quick action of the link assembly 21. Here, the elastic assembly is a prior art, so it is not shown in the drawings. One end of the output assembly 26 away from the link assembly 21 cooperates with the moving contact disc to realize the opening and closing operations of the moving contact disc. Here, the moving contact disc specifically drives the moving contact to move, realizing the disconnection or connection between the moving contact and the static contact. The structure of the moving contact disc is a prior art, so it will not be described in detail in this embodiment.

[0068] The locking assembly is used to lock and unlock the jump latch 19. In this embodiment, the locking assembly includes a rotatably arranged lock fastener 29 and a rotatably arranged re-fastener 30. When the operating mechanism is in the closing state, the re-fastener 30, the lock fastener 29 and the jump latch 19 are in a balanced state, and at this time the operating mechanism will remain in the closing state; in this state, if the re-fastener 30 is driven to rotate (due to the actuation of the release 28), the balance state of the three is broken, and under the action of the elastic assembly, the operating mechanism performs the opening operation, and the operating mechanism is in the free tripping state. When pushing the operating mechanism to re-lock (not the re-fastener, but a term for an action of an operating mechanism in this field), the lever 12 drives the jump latch 19 to rotate so that the locking assembly cooperates with the jump latch 19 to form a balanced state (i.e., the locking effect). When the re-fastener 30, the lock fastener 29 and the jump latch 19 are in a cooperating state, manually performing the opening and closing operations on the operating mechanism, the operating mechanism can be normally opened and closed, and will not cause the cooperating state of the re-fastener 30, the lock fastener 29 and the jump latch 19 to be released. In this case, the operating mechanism only has the closing state and the opening state, and there is no free tripping state; only when performing an electric operation (i.e., the release 28 is actuated) in the closing state, the balance between the re-fastener 30 and the lock fastener 29 is broken by the release 28. At this time, after tripping, the operating mechanism changes to the free tripping state. When a closing operation is required, a re-locking operation needs to be performed first to make the re-fastener 30 and the lock fastener 29 cooperate again.

[0069] With this structural arrangement, the first linkage shaft 18 is directly set to rotate synchronously with the lever 12, and the rotation centers between the two are the same. The force from the first linkage shaft 18 can directly drive the lever 12 to rotate, achieving the effect of a direct driving force, making the driving force more direct and pure, which is beneficial to the rotation of the lever 12.

[0070] Specifically, as shown in the appendix Figure 16 As shown, the lever 12 is of a U-shaped structure. The first linkage shaft 18 is connected to one side arm of the lever 12. Here, the first linkage shaft 18 and the lever 12 are formed into a linkage by welding or other fixing methods. This structure forms the linkage effect of the single side arm, and the first linkage shaft 18 will not affect the internal layout, specifically referring to the space of the cavity inside the U-shaped lever 12. The upper connecting rod, the lower connecting rod, the elastic component, and the output component 26 are all accommodated in this cavity. After the first linkage shaft 18 is placed outside, the output component 26 can adjust the relevant structure according to actual needs. At this time, the rotation axis of the output component 26 can be set to be coaxial with the rotation axis of the moving contact disc, or can be non-coaxial. When the rotation axis of the output component 26 is non-coaxial with the first linkage shaft 18, the transmission between the two can be formed through a transmission structure. Here, the transmission structure can be a connecting piece 27, and the connecting piece 27 is used for connecting the two, or the transmission can be formed through a gear structure.

[0071] Specifically, as shown in the appendix Figures 17 - 21As shown, the lever 12 is of U-shaped structure. The first linkage shaft 18 is linked with the lever 12, and the first linkage shaft 18 penetrates through the two side arms of the lever 12. Here, the first linkage shaft 18 and the lever 12 are formed by welding or other fixing means to form the linkage between the two. The first linkage shaft 18 adopts a penetrating manner to improve the linkage effect of the lever 12. It should be noted here that when the first linkage shaft 18 adopts a penetrating manner, the first linkage shaft 18 will interfere with the chamber inside the U-shaped lever 12, thus affecting the overall layout. Specifically, after the first linkage shaft 18 penetrates, the first linkage shaft 18 is connected and matched with the starting end of the link assembly 21, and the output assembly 26 is matched with the end of the link assembly 21. There is no direct contact between the starting end and the end, and the two are driven by a number of link members to form an indirect transmission. Therefore, the first linkage shaft 18 will affect the layout of the output assembly 26. In this embodiment, the output assembly 26 is sleeved on the first linkage shaft 18, and the output assembly 26 and the first linkage shaft 18 form relative rotation, that is, when the first linkage shaft 18 rotates, it will not directly drive the output assembly 26 to rotate, and when the output assembly 26 rotates, it will not drive the first linkage shaft 18 to rotate. The specific structure here can be that the output assembly 26 is provided with a rotating hole 261, and the cross-sectional dimension of the rotating hole 261 is larger than the cross-sectional dimension of the first linkage shaft 18. For example, the cross-section of the rotating hole 261 is circular, and the cross-section of the first linkage shaft 18 is runway-shaped or square, or, the cross-sections of both can also be circular, as long as it is ensured that there is no direct interference between the two during the rotation process. The other end of the output assembly 26 passes through the side arm of the lever 12 close to the moving contact disk, so that the other end of the output assembly 26 is matched with the moving contact disk. In addition, as shown in the appendix Figures 17 - 18 As shown, the output assembly 26 can also be of shaft structure. One of the output assembly 26 or the first linkage shaft 18 is a hollow shaft, and the other is accommodated in the hollow shaft, which can also achieve the effect of relative rotation. In the above structure, the rotation axis of the output assembly 26 and the rotation axis of the first linkage shaft 18 can be coaxial or non-coaxial. Those skilled in the art can adjust according to actual needs.

[0072] Specifically, as shown in the appendix Figures 22 - 24As shown, the first linkage shaft 18 passes through both side arms of the lever 12. There is no intersection between the first linkage shaft 18 and the output assembly 26. That is, in order to give sufficient space to the first linkage shaft 18, the output assembly 26 adopts a yielding structure. At this time, the rotation axis of the first linkage shaft 18 and the rotation axis of the output assembly 26 must not be coaxial. Therefore, a transmission structure is required to form the transmission between the output assembly 26 and the moving contact disk. Here, the transmission structure can be the connecting piece 27, and the connecting piece 27 is used to connect the two. It can also form the transmission through a gear structure. In addition, other transmission methods can also be adopted to realize the output of the output assembly 26. In this embodiment, the output assembly 26 can be a shaft structure, and the output assembly 26 can also adjust the corresponding structure according to the actual situation, only need to ensure that it finally forms a linkage with the moving contact disk. In this embodiment, the rotation axis of the first linkage shaft 18 and the rotation axis of the moving contact disk can be coaxial or non-coaxial.

[0073] Specifically, as shown in the appendix Figures 1 - 10 As shown, it further includes a knob 11 and a second transmission unit 101. The knob 11 is rotatably arranged. The total rotation stroke of the knob 11 is the first angle, and the total rotation stroke of the first linkage shaft 18 is the second angle. The first angle is greater than the second angle. The second transmission unit 101 is connected between the knob 11 and the first linkage shaft 18. The knob 11 and the lever 12 with different total strokes are transmitted through the second transmission unit 101. The second transmission unit 101 converts the angle so that the rotation angle of the knob 11 matches the opening and closing angles of the lever 12. For the above structure, the knob 11 can either be directly sleeved on the first linkage shaft 18 to realize the opening and closing of the operating mechanism, or the knob 11 is connected to the first linkage shaft 18 through the second transmission unit 101 to realize the opening and closing of the operating mechanism, which can be adjusted by those skilled in the art according to actual needs. With this structural setting, the second transmission unit 101 converts the angle so that the rotation angle of the knob 11 matches the opening and closing angles of the lever 12. Secondly, the rotation axis of the output end of the second transmission unit 101 and the rotation axis of the lever 12 are coaxial, making the assembly more concise. Compared with non-coaxial setting, different positioning and installation are required between the rotation axis of the lever 12 and the output end of the second transmission unit 101, and a transmission component is also required for transmission, resulting in a complex overall assembly.

[0074] There are many choices for the second transmission unit 101, and it can be completed by using the dead stroke: Specifically, as shown in the appendix Figures 1 - 10As shown in the figure, the second transmission unit 101 includes a linkage assembly 13 and an energy storage assembly 14. One end of the linkage assembly 13 is synchronously rotated with the knob 11. The linkage assembly 13 is provided with a first cavity 15 that cooperates with the first linkage shaft 18. The first linkage shaft 18 penetrates into the first cavity 15. There is an idle stroke between the first linkage shaft 18 and the first cavity 15. After the relative rotation between the first cavity 15 and the first linkage shaft 18 eliminates the idle stroke, the two come into contact to achieve a transmission connection. Here, the idle stroke specifically means that when the first linkage shaft 18 rotates, it does not directly drive the first cavity 15 to rotate. Instead, after the two rotate relative to each other by a certain angle (eliminating this idle stroke), the first linkage shaft 18 then abuts against the first cavity 15 to form a linkage effect. Conversely, the same is true. The first cavity 15 does not directly drive the first linkage shaft 18 to rotate. Instead, it first eliminates the trajectory of the idle stroke and then abuts against the first linkage shaft 18 to form a linkage effect. The angle of the idle stroke here can be adjusted according to actual needs.

[0075] Specifically, as shown in the attached Figure 8 figure, the first linkage shaft 18 is provided with a first acting surface 181 and a second acting surface 182. The first acting surface 181 and the second acting surface 182 are arranged at an obtuse angle. In this embodiment, the included angle between the two is 120°. The first acting surface 181 and the second acting surface 182 are symmetrically arranged. One end of the first acting surface 181 is connected to one end of the second acting surface 182 through a first connecting surface 183. Here, the first connecting surface 183 can be an arc surface or a plane. The other end of the first acting surface 181 is connected to the other end of the second acting surface 182 through a second connecting surface 184 to form a closed structure. Here, the second connecting surface 184 is an arc surface. The wall of the first cavity 15 includes a first plane 151 and a third connecting surface 152. The two ends of the first plane 151 are respectively connected to the two ends of the third connecting surface 152 to form a closed structure. Here, the third connecting surface 152 is an arc surface.

[0076] The so-called idling stroke here refers to the angle of relative rotation between the first linkage shaft 18 and the linkage assembly 13 before the first plane 151 contacts the first acting surface 181 or the first acting surface 181. It includes the following three states: the first state, a first idling stroke is provided between the first plane 151 and the second acting surface 182; the second state, a second idling stroke is provided between the first plane 151 and the second acting surface 182; the third state, a third idling stroke is provided between the first plane 151 and the first acting surface 181. In this embodiment, the rotation angles of the first idling stroke, the second idling stroke, and the third idling stroke are equal. The cooperation between the first plane 151 and the first acting surface 181 and the second acting surface 182 forms the effect of the idling stroke, and for different states, different idling stroke rotation effects are corresponding. In addition, the cooperation of the shaft and the waist-shaped hole can also be adopted to form an effect of an idling stroke, that is, the distance that the shaft moves from one end of the waist-shaped hole to the other end is the idling stroke.

[0077] The total rotation stroke of the knob 11 is the first angle, and the total rotation stroke of the lever 12 is the second angle (i.e., the total rotation stroke of the first linkage shaft 18). The first angle is greater than the second angle, and the angle of the idling stroke is the first angle minus the second angle. In this embodiment, the first angle is 90°, the second angle is 30°, and at this time the angle of the idling stroke is 60°. That is, whether it is manual closing or manual opening, when the driving knob 11 rotates, after rotating 60°, the first cavity 15 abuts against the first linkage shaft 18 (if it is opening, it abuts against the second acting surface 182 to achieve transmission, and if it is closing, it abuts against the first acting surface 181 to achieve transmission). The first cavity 15 drives the first linkage shaft 18 to rotate, thereby realizing the rotation effect of the lever 12.

[0078] As shown in the Figures 2 - 7 accompanying figure, the linkage assembly 13 includes a second linkage shaft 20. The first cavity 15 is arranged at one end of the second linkage shaft 20 facing the lever 12, that is, the first cavity 15 is provided at the lower end of the second linkage shaft 20.

[0079] In order to reduce a certain operating force, it further includes an energy storage component 14 and a driving part 131.

[0080] The linkage assembly 13 here includes a linkage member 16, and the linkage member 16 is set to move synchronously with the second linkage shaft 20. The driving part 131 is arranged on the linkage member 16, and here the driving part 131 has an effect similar to a cam. The cooperation between the second linkage shaft 20 and the linkage member 16 better realizes the linkage effect.

[0081] The energy storage component 14 cooperates with the driving part 131. During the rotation of the knob 11, the energy storage component 14 first stores energy and then releases energy to provide a driving force for the rotation of the linkage component 13. This energy storage of the energy storage component 14 is completed before the idling stroke is completely eliminated. In this way, energy storage can be achieved during the idling stroke stage, which can ensure the operating feel of the knob 11. At the same time, during the energy release stage, the operating driving force can be reduced (because the energy storage component 14 that releases energy generates a certain acting force).

[0082] Specifically, as shown in the appendix Figure 7 As shown, the linkage 16 includes a first component 161, a second component 162 and a plurality of pin shafts 163. The first component 161 and the second component 162 are arranged in parallel. The pin shafts 163 connect the first component 161 and the second component 162, and the pin shafts 163 form a fixing effect between the first component 161 and the second component 162. The first component 161 and the second component 162 cooperate to form a first leg 164, and the driving part 131 is arranged on the first leg 164. It should be noted here that a pin shaft 163 is also fixed on the first leg 164, and the pin shaft 163 located on the first leg 164 is the driving part 131, that is, the pin shaft 163 located on the first leg 164 abuts and cooperates with the energy storage component 14. Through the up-and-down cooperation setting of the linkage 16, the strength is increased, and at the same time, the contact area is increased, so that when the driving part 131 abuts against the sliding part, a better supporting and abutting effect can be achieved, preventing the linkage 16 from being damaged. In addition, the linkage 16 can also be an integrally formed structure, that is, a cam structure, but the strength and height of the linkage 16 need to be ensured. In this embodiment, the connection is formed by the cooperation of two upper and lower components, which is simple to process and has low cost.

[0083] Specifically, as shown in the appendix Figures 1 - 5As shown, it further includes a bracket 17. The energy storage component 14 includes a sliding member 141 and an elastic member 142. The sliding member 141 slides relative to the bracket 17. Here, the bracket 17 is arranged on the body of the disconnector, and the bracket 17 is fixedly connected to the body. One end of the elastic member 142 is connected to the sliding member 141, and the other end is directly connected to the bracket 17 (in addition, it can also be connected to the housing, which is equivalent to being indirectly connected to the bracket 17). The sliding member 141 cooperates with the driving portion 131, and a critical point is formed during the movement of the sliding member 141 and the driving portion 131. The mutual cooperation among the sliding member 141, the elastic member 142, and the linkage member 16 forms the cooperation effect between the first linkage shaft 18 and the first cavity 15 during rotation. The elastic member 142 plays an energy storage and energy release effect. Before moving to the critical point, the elastic member 142 plays an energy storage effect. When crossing the critical point, the elastic member 142 will quickly release energy to accelerate rotation. In addition, a positioning and guiding structure is provided between the bracket 17 and the sliding member 141, that is, the bracket 17 is provided with a positioning pin 171, and the sliding member 141 is provided with a positioning hole 1411. The positioning pin 171 passes through the positioning hole 1411, and the positioning pin 171 slides relative to the positioning hole 1411 to form a positioning and guiding effect. At the same time, the cooperation between the positioning pin 171 and the positioning hole 1411 can also correspondingly reduce the acting force of the elastic member 142 on the sliding member 141.

[0084] Specifically, the sliding member 141 is provided with a through hole 1412, and the inner wall of the through hole 1412 is provided with a raised portion 1413. During the rotation of the linkage assembly 13, the driving portion 131 moves along the raised portion 1413. Before reaching the highest point of the raised portion 1413, the elastic member 142 stores energy, and after crossing the highest point of the raised portion 1413, the elastic member 142 releases energy; when the driving portion 131 reaches the highest point of the raised portion 1413, the wall of the first cavity 15 and the first linkage shaft 18 are still not in contact. In this embodiment, the linkage assembly 13 is accommodated in the through hole 1412. The sliding member 141 is arranged at one end of the bracket 17. One end of the elastic member 142 is connected to the sliding member 141, and the other end of the elastic member 142 is connected to the end of the bracket 17 away from the sliding member 141. In this embodiment, the elastic member 142 is a tension spring. The angle at which the knob 11 rotates to the critical point is smaller than the angle of the idle stroke of the knob 11, that is, when reaching the critical point position, the knob 11 has not completed the rotation of the idle stroke, that is, the first linkage shaft 18 and the first cavity 15 have not formed a linkage. This kind of structure is simple to process and has good practicability. Here, how the sliding member 141, the elastic member 142, and the linkage member 16 form the critical point can also be realized by other structures, such as the critical point realized by a connecting rod structure and a torsion spring, and it can also be a spring structure, etc.

[0085] Specifically, the sliding member 141 is a sheet-like structure, and the number of the elastic members 142 is at least 2, and the elastic members 142 are arranged in parallel. One end of each elastic member 142 is connected to the sliding member 141, and the other end of the elastic member 142 is connected to the bracket 17. The sliding member 141 adopts a sheet-like structure, so that the overall thickness is reduced and space is saved. Through the cooperation of multiple elastic members 142, force decomposition is formed, which can also reduce the thickness of the sliding member 141 in disguise. The elastic member 142 can also reduce the re-clamping force and the closing force. When the working environment changes, the acceleration effect of the sliding member 141 can be improved by increasing the number of elastic members 142.

[0086] Specifically, the elastic member 142 will exert a certain force on the sliding member 141 in the closed position. When the tripping operation is performed, the elastic component of the first transmission unit 102 acts to rotate the lever 12 (equivalent to the rotation of the first linkage shaft 18). At this time, the second linkage shaft 20 will also rotate a corresponding angle under the action of the elastic member 142, and the knob 11 will also rotate accordingly. This structural setting achieves the effect of free tripping, ensures accurate indication of the knob tripping, and prevents the situation where the position of the knob is difficult to determine during free tripping due to idle travel, so that the operator can know that this is the tripping position. In this embodiment, the elastic member 142 takes a tension spring as an example, and those skilled in the art can also adjust the type of the elastic member 142 according to actual needs.

[0087] Specifically, the first component 161 cooperates with the second component 162 to form a second leg 165 and a third leg 166. The second leg 165 and the third leg 166 are symmetrically arranged, and the second leg 165 and the third leg 166 are arranged on both sides of the first leg 164. The second leg 165 and the third leg 166 also have the pin 163 passing through them to improve the strength. At the critical point, the second leg 165 and the third leg 166 respectively cooperate with the side wall of the through hole 1412 to form a pressure dividing effect, so that the pin 163 located on the first leg 164 will not be subjected to excessive pressure. The pressure source here is specifically the force of the elastic member 142.

[0088] Specifically, as attached Figures 2 - 5As shown, the overall working principle is as follows. In the first state, which is the closing position, the first plane 151 abuts against the first acting surface 181. The first plane 151 and the second acting surface 182 form a first idle stroke, and the angle of the first idle stroke is 60°. When tripping occurs, the elastic component of the first transmission unit 102 acts, causing the lever 12 to rotate (equivalent to the rotation of the first linkage shaft 18). The second linkage shaft 20 will also rotate by a corresponding angle under the action of the elastic member 142, and at the same time, the knob 11 will also rotate accordingly. In this embodiment, when tripping, taking the rotation angle of the lever 12 as 10° as an example, at this time, the second linkage shaft 20 will also rotate by 10°, making the first plane 151 fit and abut against the first acting surface 181. The first plane 151 and the second acting surface 182 form a second idle stroke, and the angle of the second idle stroke is 60°. Thus, it is ensured that at the tripping position, the idle stroke is also 60°, and this position is the second state. For the operation from the tripping position to the reclosing position, the knob 11 needs to rotate by 80°. Rotating the knob 11 causes the second linkage shaft 20 to rotate. When passing through the critical point, there is still a 25° idle stroke between the first plane 151 and the second acting surface 182. Continuing to rotate the knob 11, at this time, under the action of the elastic member 142, the reclosing operation is accelerated, causing the first linkage shaft 18 to rotate, realizing the rotation of the lever 12, and finally realizing the reclosing operation. In this embodiment, taking the opening and closing angle of the lever 12 as 30° as an example, since the lever 12 rotates by 10° during the tripping process, from the tripping position to the reclosing position, the lever 12 rotates by 20°, and the overall lever 12 also rotates by 30°. At this time, the reclosing position is the third state.

[0089] In the third state, the first plane 151 abuts against the second acting surface 182. At this time, the first plane 151 and the first acting surface 181 form a third idle stroke, and the angle of the third idle stroke is also 60°. From the reclosing position to the closing position, the rotation angle of the knob 11 is 90°. The critical point position is at the 45° position of the rotation angle of the knob 11. Therefore, when the knob 11 rotates by 45°, it reaches the critical point position, and there is still a 15° idle stroke at this time. After crossing the critical point, under the action of the elastic member 142, the closing operation is accelerated, causing the first linkage shaft 18 to rotate, realizing the rotation of the lever 12, and finally realizing the closing operation.

[0090] Specifically, as shown in the appendix Figure 10 As shown, the connecting rod assembly 21 includes an upper connecting rod and a lower connecting rod. The elastic component connected to the lever 12 causes the upper connecting rod to rotate, the upper connecting rod drives the lower connecting rod to rotate, and the lower connecting rod drives the output component 26 to rotate.

[0091] Specifically, the rotation axis of the knob 11 and the rotation axis of the lever 12 can be coaxially arranged or non-coaxially arranged.

[0092] Embodiment 2

[0093] This embodiment provides an operating mechanism. As shown in the appendix Figures 10 - 15 shown, the difference between Embodiment 2 and Embodiment 1 lies in the different structures of the second transmission unit 101.

[0094] The second transmission unit 101 includes a planetary gear module 33. The input end and the output end are arranged on the planetary gear module 33. Here, it should be noted that the planetary gear module 33 has the function of adjusting the angle between the input end and the output end. For example, when the rotation angle of the input end is 90°, the angle of the output end can be a small angle, that is, an acute angle. In this embodiment, the angle conversion between the input end and the output end can be adjusted by the transmission ratio to meet the corresponding linkage relationship. The angle of the output end is based on the angle of the lever 12 for opening and closing. The input end is linked with the knob 11. When the knob 11 rotates, the input end also rotates accordingly. Here, no matter how many degrees the knob 11 rotates, the input end also rotates the corresponding angle. The output end is linked with the lever 12. Here, no matter how many degrees the output end rotates, the lever 12 also rotates the corresponding angle. Driving the knob 11 to realize the rotation of the lever 12. Specifically, when the knob 11 rotates 90°, the input end also rotates 90°. At this time, the angle of the output end is an acute angle, specifically matching the angle of the lever 12 for opening and closing. Here, the output end is linked with the lever 12 to form the rotation of the lever 12. The rotation axis of the output end and the rotation axis of the lever 12 are arranged on the same axis.

[0095] The planetary gear module 33 includes a sun gear 34, a ring gear 35, a planet carrier 36 and planet gears 37. The planet gears 37 are located between the sun gear 34 and the ring gear 35. Here, the planet gears 37 are arranged in a circumferential array. The number of planet gears 37 can be adjusted according to actual needs. It can be two, three, four or even more. In this embodiment, three planet gears 37 are taken as an example for description. The ring gear 35 is an annular structure, that is, there is a through hole in the middle of the ring gear 35. A number of teeth are provided on the inner wall of the ring gear 35. The sun gear 34 is located in the central area of the ring gear 35. Here, the rotation axis of the sun gear 34 and the rotation axis of the ring gear 35 are coaxial. The sun gear 34 meshes with the planet gears 37, and the planet gears 37 mesh with the ring gear 35. The planet gears 37 are rotatably arranged. The rotation of the planet gears 37 includes both self-rotation about its own first axis and revolution about the second axis. Here, the first axis specifically refers to the central axis of the planet gear 37, and the second axis specifically refers to the central axis of the planet carrier 36. In this embodiment, the side surface of the planet gear 37 is a toothed structure, which can be straight teeth or helical teeth. The planet carrier 36 is fixed to the planet gears 37 and is rotatably arranged about the second axis. The planet teeth and the planet carrier 36 can be fixed by rivet connection or other fixing methods to achieve the fixing effect. It should be noted that the angle conversion between the input end and the output end can be achieved by adjusting the transmission ratio between the gears, so as to control the corresponding angle conversion, so that the rotation angle of the knob 11 matches the opening and closing angle of the lever 12. In this embodiment, the rotation angle of the knob 11 is matched with the opening and closing angle of the lever 12 through a single row of planet gears 37. In addition, the matching effect of the angles can also be achieved through a double row of planet gear 37 structures or other planet gear 37 structures. It can also be achieved by the cooperation of upper and lower layers of planet gear 37 structures, or by the cooperation of gear sets, or by the cooperation of double-connected tooth gear sets.

[0096] Through the setting of the planetary gear module 33, the torque is amplified, and the transmission ratio is used to match the rotation angle of the knob 11 with the opening and closing angles of the lever 12, so as to meet the rotation effect of the lever 12. Secondly, by setting the output end of the planetary gear module 33 and the rotation axis of the lever 12 to be coaxial, the assembly is more streamlined. Compared with the non-coaxial setting of the output end of the planetary gear module 33 and the rotation axis of the lever 12, different positioning and installation are required between the lever 12 and the planetary gear module 33, and a transmission component is also required for transmission, resulting in a complex overall structure and cumbersome assembly. The structure of the present application has a streamlined effect and improves the assembly efficiency. Finally, the planetary gear module 33 is modularly arranged, which is convenient for installation and can achieve the effect of rapid assembly. In the operation process of the entire operating mechanism, for example, when the knob 11 rotates 90°, the angle of the output end is matched with the opening and closing angles of the lever 12 through the planetary gear module 33. Here, the rotation angle of the lever 12 is a small angle, and the rotation of the lever 12 realizes the rotation of the first transmission unit 102. Through the cooperation of the link assembly 21 and the elastic component, the rotation angle is amplified, so that the rotation angle of the output component 26 is matched with the opening and closing angles of the moving contact disc. Here, the opening and closing angles of the moving contact disc are 90°. Thus, the opening and closing operations of the entire operating mechanism are realized.

[0097] Specifically, as shown in the attached Figures 13 - 14 figure, the ring gear 35 is fixed. The fact that the ring gear 35 is fixed means that when the knob 11 rotates, the ring gear 35 is in a stationary state and will not move. The sun gear 34 is rotatably arranged, that is, when the knob 11 rotates, the sun gear 34 will also rotate. The sun gear 34 is the input end, that is, the knob 11 is linked with the sun gear 34. When the knob 11 rotates 90°, the sun gear 34 also rotates 90°. When the knob 11 drives the sun gear 34 to rotate, the planet gears 37 and the planet carrier 36 are driven to rotate through the rotation of the sun gear 34. At this time, the planet carrier 36 is the output end, and the planet carrier 36 drives the lever 12 to rotate, thus realizing the opening and closing operations of the lever 12. Since the rotation angle is converted through the transmission ratio during the cooperation between the planet gears 37 and the sun gear 34, the planet carrier 36 forms a small-angle rotation effect, meeting the rotation angle requirements of the lever 12. In this embodiment, the ring gear 35 can be fixed in cooperation with the cover plate 24, the ring gear 35 can also be fixed in cooperation with the body 22 of the disconnecting switch, and the ring gear 35 can also be fixed in cooperation with the fixing member 25, and then the fixing member 25 is fixed in cooperation with the cover plate 24 or the body 22 of the disconnecting switch.

[0098] Specifically, when the ring gear 35 is fixed, specifically, when the knob 11 rotates, the ring gear 35 remains stationary and does not move. The sun gear 34 is rotatably arranged, that is, when the knob 11 rotates, the sun gear 34 also rotates. The planet carrier 36 is the input end, and the sun gear 34 is the output end. At this time, the knob 11 is linked with the planet carrier 36, and the knob 11 drives the planet carrier 36 to rotate. Through the rotation of the planet carrier 36, the planet gears 37 drive the sun gear 34 to rotate, and the sun gear 34 drives the lever 12 to rotate. The difference between this solution and the above solution lies in the different mating positions of the lever 12. In this embodiment, the linkage structure between the knob 11 and the sun gear 34 and the linkage structure between the planet carrier 36 and the lever 12 can be adjusted according to actual needs. In this embodiment, the ring gear 35 can be fixedly combined with the cover plate 24, or the ring gear 35 can be fixedly combined with the body 22 of the disconnecting switch, or the ring gear 35 can be fixedly combined with the fixing member 25, and then the fixing member 25 is fixedly combined with the cover plate 24 or the body 22 of the disconnecting switch.

[0099] Specifically, the sun gear 34 is fixed. Specifically, when the knob 11 rotates, the sun gear 34 remains stationary and does not move. The ring gear 35 is rotatable, and when the knob 11 rotates, the ring gear 35 rotates. The ring gear 35 is the input end, that is, the knob 11 is linked with the ring gear 35, and the knob 11 drives the ring gear 35 to rotate. Through the rotation of the ring gear 35, the planet gears 37 and the planet carrier 36 are driven to rotate. At this time, the planet carrier 36 is the output end, and the planet carrier 36 drives the lever 12 to rotate, thereby realizing the opening and closing operation of the lever 12. Since, during the cooperation between the planet gears 37 and the ring gear 35, the rotation angle is converted through the transmission ratio, so that the planet carrier 36 forms a small-angle rotation effect, meeting the rotation angle requirement of the lever 12. In this embodiment, the sun gear 34 can be fixedly combined with the cover plate 24, or the sun gear 34 can be fixedly combined with the body 22 of the disconnecting switch, or the sun gear 34 can be fixedly combined with the fixing member 25, and then the fixing member 25 is fixedly combined with the cover plate 24 or the body 22 of the disconnecting switch.

[0100] Specifically, the sun gear 34 is fixed. Specifically, when the knob 11 rotates, the sun gear 34 remains stationary and does not move. The ring gear 35 is rotatable, and when the knob 11 rotates, the ring gear 35 rotates. The planet carrier 36 is the input end, and the ring gear 35 is the output end. The knob 11 is linked with the planet carrier 36, and the knob 11 drives the planet carrier 36 to rotate. Through the rotation of the planet carrier 36, the planet gears 37 drive the ring gear 35 to rotate. At this time, the ring gear 35 is the output end, and the ring gear 35 drives the lever 12 to rotate. The difference between this solution and the above solution lies in the different mating positions of the lever 12.

[0101] Specifically, as shown in the appendixFigures 11 - 12 As shown, the transmission is realized between the lever 12 and the output end through the first linkage shaft 18. The first linkage shaft 18 can be set on the lever 12, and the output end is provided with a hole that matches the first linkage shaft 18; or, the first linkage shaft 18 is set on the output end, and the lever 12 is provided with a hole that matches the first linkage shaft 18. Those skilled in the art can adjust the relevant positional relationship according to actual needs. In addition, the linkage can also be achieved by bolts or buckles or other fixing methods. The transmission is realized between the knob 11 and the input end through the second linkage shaft 20. The second linkage shaft 20 can be set on the knob 11, and the input end is provided with a hole that matches the second linkage shaft 20; or, the second linkage shaft 20 is set on the input end, and the knob 11 is provided with a hole that matches the second linkage shaft 20. Those skilled in the art can adjust the relevant positional relationship according to actual needs. In addition, the linkage can also be achieved by bolts or buckles or other fixing methods.

The operating unit layer 103 includes a body 22, a cover plate 24, and an operating mechanism. The body 22 and the cover plate 24 form a chamber, and the operating mechanism is accommodated in this chamber. The specific structure of the operating mechanism has been described in detail in Example 1 and Example 2, so it will not be described in detail in this embodiment. The output component 26 is linked to the moving contact plate of the first switch unit layer.

[0104] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
