Description

Technical Field

[0001] The invention relates to the field of electrical technology, and in particular to an operating mechanism and an isolating switch. Background Art

[0002] The operating mechanism of the original disconnector is composed of several parts to form a transmission effect. However, the problem with this structure is that the parts are installed in a scattered manner, and the assembly efficiency is low. Therefore, those skilled in the art have proposed a modular installation structure, that is, the operating mechanism is formed into a module, and an installation effect is formed through modularization.

[0003] The modular structure adopts a lever structure. The problem with the structure here is that the input end of the modular operating mechanism is a small-angle input (the rotation angle is an acute angle), and the output end of the modular operating mechanism is a 90° rotation, that is, the lever rotates at a small angle to achieve the opening and closing effect. The knob cooperates with the lever, and the rotation angle of the lever is generally an acute angle (for example, more than 30°), while the rotation angle of the knob is often greater than the rotation angle of the lever (for example, 90°). How to achieve the matching of the rotation angle of the knob and the opening and closing angle of the lever has become a technical problem that technicians in this field urgently need to solve. Summary of the invention

[0004] Therefore, the technical problem to be solved by the present invention is how to achieve the matching of the rotation angle of the knob and the opening and closing angle of the lever. To this end, an operating mechanism includes: a first transmission unit, a lever and a second transmission unit, wherein the lever connects the first transmission unit and the second transmission unit;

[0005] The first transmission unit includes a linkage component and an energy storage component, one end of the linkage component is arranged to rotate synchronously with the knob; one of the linkage component and the lever is provided with a first linkage shaft, and the other of the linkage component and the lever is provided with a first cavity matched with the first linkage shaft, and there is an idle stroke between the first cavity and the first linkage shaft, and after the first cavity and the first linkage shaft rotate relative to each other to eliminate the idle stroke, the two are in contact to achieve transmission connection; the linkage component is provided with a driving part; the energy storage component cooperates with the driving part, and in the process of driving the knob to realize the rotation of the lever, the energy storage component first stores energy and then releases energy to provide a force for the rotation of the linkage component, and the energy storage of the energy storage component is completed before the idle stroke is eliminated; the rotation axis of the first linkage shaft and the rotation axis of the lever are arranged coaxially; the total rotation stroke of the knob is a first angle, and the total rotation stroke of the first linkage shaft is a second angle, and the first angle is greater than the second angle; the first 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 first transmission unit;

[0006] The second transmission unit comprises a connecting rod assembly, an output assembly, a trip button and an elastic assembly, wherein the trip button is rotatably connected to the lever, one end of the connecting rod assembly is rotatably connected to the trip button, the other end of the connecting rod assembly is connected to the output assembly, and a joint position of the connecting rod assembly is connected to the lever through the elastic assembly; the output assembly is rotatably arranged, and under the action of the connecting rod assembly, the movable contact plate of the disconnector is driven to rotate to realize opening and closing;

[0007] The locking assembly is used to lock the jump buckle and unlock the jump buckle.

[0008] The first linkage shaft includes a first action surface and a second action surface which are arranged at an obtuse angle with each other. The first cavity is provided with a first plane. After the first plane contacts the first action surface or contacts the second action surface, the two form a transmission connection. The idle stroke refers to the angle of relative rotation between the linkage component and the first linkage shaft before the first plane comes into contact with the first action surface or contacts with the second action surface.

[0009] The linkage assembly includes a second linkage shaft and a linkage member, the second linkage shaft and the linkage member are arranged for synchronous movement, the first cavity is opened at one end of the second linkage shaft toward the lever, the other end of the second linkage shaft is linked to the knob, and the driving part is arranged on the linkage member.

[0010] The linkage member includes a first component, a second component and a plurality of pins, the first component and the second component are arranged in parallel, the pins connect the first component and the second component, the first component and the second component cooperate to form a first support leg, and the driving part is arranged on the first support leg.

[0011] It also includes a bracket, the energy storage component 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.

[0012] The sliding part 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 part stores energy, and after passing the highest point of the raised portion, the elastic part releases energy. When the driving part reaches the highest point of the raised portion, the wall of the first cavity is still not in contact with the first linkage shaft.

[0013] The sliding member is a sheet-like structure, the number of the elastic members is at least 2, and the elastic members are arranged in parallel.

[0014] The lever is a U-shaped structure, and the first linkage shaft is connected to one side arm of the lever; or, the lever is a U-shaped structure, the first linkage shaft is linked to the lever, and the first linkage shaft passes through two side arms of the lever.

[0015] The first linkage shaft and the output assembly are coaxially arranged; or, the first linkage shaft and the output assembly are not coaxially arranged.

[0016] Therefore, the technical problem to be solved by the present invention is how to achieve the matching of the rotation angle of the knob and the opening and closing angle of 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.

[0017] The technical solution of the present invention has the following advantages:

[0018] 1. An operating mechanism provided by the present invention adopts such a structural setting, and through the idle stroke, the extra rotation angle is consumed during the rotation process, and the rotation angle of the knob is matched with the opening and closing angle of the lever, so as to meet the rotation effect of the lever; the energy storage component forms the effect of storing and releasing energy during the whole movement process, which can play the effect of hindering or helping the rotation, and realize the reduction of the re-clamping force and the closing force; secondly, the rotation axis of the first linkage shaft and the rotation axis of the lever are set as the same axis, so that the assembly is more streamlined, and compared with the different axis settings, the rotation axis between the lever and the first linkage shaft is It needs to be installed through different positioning and also needs to be transmitted by the transmission assembly, which makes the overall assembly complicated; the operation process of the entire operating mechanism, for example, by turning the knob 90°, the rotation angle of the first linkage shaft is matched with the opening and closing angle of the lever through the idle stroke. Here, the rotation angle of the lever is a small angle. The rotation of the lever realizes the rotation of the second transmission unit. Through the cooperation of the connecting rod assembly and the elastic assembly, the rotation angle is further magnified, so that the rotation angle of the output assembly matches the opening and closing angle of the moving contact disk. Here, the opening and closing angle of the moving contact disk is 90°, thereby realizing the opening and closing operation of the entire operating mechanism.

[0019] 2. The present invention provides an operating mechanism, in which the first plane cooperates with the first action surface and the second action surface to form an idle stroke effect, and different idle stroke rotation effects correspond to different states. In addition, the shaft and the waist-shaped hole can also be used to cooperate to form an idle stroke effect, that is, the distance the shaft moves from one end of the waist-shaped hole to the other end of the waist-shaped hole is the idle stroke.

[0020] 3. In the operating mechanism provided by the present invention, the cooperation between the second linkage shaft and the linkage member can better achieve the linkage effect.

[0021] 4. In an operating mechanism provided by the present invention, the linkage parts are arranged in a coordinated manner up and down, thereby increasing the strength and the contact area, so that when the driving part and the sliding part are against each other, a better supporting effect can be achieved to prevent the linkage parts from being damaged.

[0022] 5. An operating mechanism provided by the present invention, in which the sliding part, the elastic part and the linkage part cooperate with each other, forming a cooperation effect between the first linkage shaft and the first cavity during the rotation process, and the elastic part plays an energy storage and energy release effect. Before moving to the critical point, the elastic part plays an energy storage effect. When crossing the critical point, the elastic part will quickly release energy and accelerate the rotation (the most important thing is to complete the energy storage during idling, which can provide spring force in the non-idling state, reduce the manual operating force, and make the hand feel better).

[0023] 6. The operating mechanism provided by the present invention has a sliding member with such a structural arrangement, which is simple to process and has good practicality. Here, how the sliding member, elastic member, and linkage member form a critical point can also be achieved through other structures, such as a critical point achieved by a connecting rod structure and a torsion spring.

[0024] 7. In an operating mechanism provided by the present invention, a sliding part adopts a sheet-like structure, so that the overall thickness is reduced and space is saved. A plurality of elastic parts cooperate with each other to form a force decomposition, thereby reducing the thickness of the sliding part in disguise.

[0025] 8. The present invention provides an operating mechanism, which has a structure that forms a one-sided linkage effect. The output component can adjust the relevant structure according to actual needs. It should be noted that the rotation axis of the first linkage shaft and the rotation axis of the moving contact disk are coaxially arranged, and the output of the second transmission unit can be achieved through a four-bar structure or a five-bar structure, so that the rotation axis of the lever and the rotation axis of the moving contact disk are coaxially arranged; the first linkage shaft adopts a through-type manner to improve the linkage effect of the lever.

[0026] 9. In the operating mechanism provided by the present invention, the first linkage shaft and the output assembly can achieve a transmission effect by being arranged coaxially or on different axes, and it is only necessary to ensure that the rotation axis of the lever and the rotation axis of the moving contact plate are arranged coaxially.

[0052] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0053] Example 1

[0054] This embodiment provides an operating mechanism, as shown in the attached Figure 1-Figure 19 As shown, it includes a first transmission unit 101 , a lever 12 and a second transmission unit 102 , and the lever 12 connects the first transmission unit 101 and the second transmission unit 102 .

[0055] The first transmission unit 101 includes a linkage component 13 and an energy storage component 14. One end of the linkage component 13 is linked to the knob 11, and the other end of the linkage component 13 cooperates with the lever 12. One of the linkage component 13 and the lever 12 is provided with a first linkage shaft 18, and the other of the linkage component 13 and the lever 12 is provided with a first cavity 15 that cooperates with the first linkage shaft 18. When the linkage component 13 is provided with the first linkage shaft 18, the lever 12 is provided with the first cavity 15; conversely, when the linkage component 13 is provided with the first cavity 15, the lever 12 is provided with the first linkage shaft 18. In this embodiment, the lever 12 is provided with the first linkage shaft 18 and the linkage component 13 is provided with the first cavity 15 as an example for description. The first linkage shaft 18 penetrates into the first cavity 15, and there is an idle stroke between the first linkage shaft 18 and the first cavity 15. After the first cavity 15 and the first linkage shaft 18 rotate relative to each other to eliminate the idle stroke, the two are in contact to achieve transmission connection. The idle stroke here specifically means that when the first linkage shaft 18 rotates, it will not directly drive the first cavity 15 to rotate, but the two will rotate relative to each other for a certain angle (eliminating this idle stroke), and then the first linkage shaft 18 will contact with the first cavity 15 to form a linkage effect. Conversely, the same is true. The first cavity 15 will not directly drive the first linkage shaft 18 to rotate, but will first eliminate the trajectory of the idle stroke, and then contact with the first linkage shaft 18 to form a linkage effect. The angle of the idle stroke here can be adjusted according to actual needs. The linkage component 13 is provided with a driving part 131, and when the linkage component 13 is rotating, the driving part 131 also rotates accordingly. The energy storage component 14 cooperates with the driving part 131 to drive the knob 11 to realize the rotation of the lever 12. Specifically, when the driving knob 11 rotates, the knob 11 drives the linkage component 13 to rotate. At this time, the first cavity 15 also rotates accordingly. When the rotation angle of the first cavity 15 is consistent with the angle of the idle stroke, the first cavity 15 and the first linkage shaft 18 are offset, and the first cavity 15 drives the first linkage shaft 18 to rotate, thereby realizing the rotation effect of the lever 12. 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 (that is, the total rotation stroke of the first linkage shaft 18). The first angle is greater than the second angle, and the angle of the idle stroke is the first angle minus the second angle. In this embodiment, the first angle is 90°, the second angle is 30°, and the angle of the idle stroke is 60°. That is, whether in manual closing or manual opening, when the driving knob 11 is rotated, after rotating 60°, the first cavity 15 and the first linkage shaft 18 are offset, and the first cavity 15 drives the first linkage shaft 18 to rotate, thereby realizing the rotation effect of the lever 12. 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 force for the rotation of the linkage component 13. The energy storage of the energy storage component 14 is completed before the idling stroke is completely eliminated.In this way, energy storage is achieved during the idle stroke stage, which can ensure the operating feel of the knob 11, and at the same time, the operating driving force can be reduced during the energy release stage (because the energy storage component 14 that releases energy generates a certain force). The rotation axis of the first linkage shaft 18 and the rotation axis of the lever 12 are coaxially arranged.

[0056] The second transmission unit 102 includes a connecting rod assembly 21, an output assembly 26, a jumper 19 and an elastic assembly. Here, the connecting rod assembly 21 is an upper connecting rod and a lower connecting rod (the joint position is the hinge position of the two), and it can also be a three-link rod, or other connecting rod structures. The jumper 19 is rotatably connected with the lever 12, and the lever 12 can drive the jumper 19 to rotate. One end of the connecting rod assembly 21 and the jumper 19 are also rotatably connected, and the other end of the connecting assembly cooperates with the output assembly 26 for transmission, so that the connecting rod assembly 21 drives the output assembly 26 to rotate. The joint position of the connecting rod assembly 21 is connected to the lever 12 by an elastic assembly. The elastic assembly (i.e., the main tension spring) is used to realize the rapid action of the connecting rod assembly 21. The elastic assembly is a prior art here, so it is not reflected in the accompanying drawings. One end of the output assembly 26 away from the connecting rod assembly 21 cooperates with the moving contact disk to realize the opening and closing operations of the moving contact disk. Here, the moving contact disk specifically drives the moving contact to move to realize the disconnection or connection between the moving contact and the static contact. The structure of the moving contact disk is a prior art, so it is not described in detail in this embodiment.

[0057] The locking assembly is used to lock and unlock the tripping buckle 19. In this embodiment, the locking assembly includes a rotatable locking member 29 and a rotatable refastening member 30. When the operating mechanism is in the closed state, the refastening member 30, the locking member 29 and the tripping buckle 19 are in a balanced state, and the operating mechanism will remain in the closed state; in this state, if the refastening member 30 is driven to rotate (because the releaser 28 is actuated), the balance state of the three is broken, and the operating mechanism performs the opening operation under the action of the elastic assembly, and the operating mechanism is in a free tripping state. When the operating mechanism is pushed to refasten (not a refastening member, but a name for an operating mechanism action in this field), the lever 12 drives the tripping buckle 19 to rotate so that the locking assembly cooperates with the tripping buckle 19 to form a balanced state (i.e., a locking effect). When the refastener 30, the lock member 29 and the tripping release 19 are in a matched state, the operating mechanism is manually opened and closed, and the operating mechanism can be opened and closed normally, and the matched state of the refastener 30, the lock member 29 and the tripping release 19 will not be released. In this case, the operating mechanism only has an open state and a closed state, and no free tripping state; only when electric operation is performed in the closed state (i.e., the releaser 28 is actuated), the balance between the refastener 30 and the lock member 29 is broken by the releaser 28. At this time, after the tripping, the operating mechanism is transformed into a free tripping state. When the closing operation is required, the refastener operation needs to be performed first to make the refastener 30 and the lock member 29 match again.

[0058] With this structural setting, the extra rotation angle is consumed during the rotation process through the idle stroke, and the rotation angle of the knob 11 is matched with the opening and closing angle of the lever 12, so as to meet the rotation effect of the lever 12; the energy storage component 14 forms the effect of energy storage and energy release during the whole movement process, which can help the rotation effect and realize the reduction of the re-clamping force and the closing force; secondly, the rotation axis of the first linkage shaft 18 and the rotation axis of the lever 12 are set as the same axis, so that the assembly is more streamlined. Compared with different axis settings, the rotation axis of the lever 12 and the first linkage shaft 18 need to be installed through different positioning, The transmission component is also required for transmission, which makes the overall assembly complicated. The operation process of the entire operating mechanism, for example, by rotating the knob 11 90°, the rotation angle of the first linkage shaft 18 is matched with the opening and closing angle of the lever 12 through the idle stroke. Here, the rotation angle of the lever 12 is a small angle. The rotation of the lever 12 realizes the rotation of the second transmission unit 102. Through the cooperation of the connecting rod assembly 21 and the elastic assembly, the rotation angle is further enlarged, so that the rotation angle of the output assembly 26 matches the opening and closing angle of the moving contact disk. Here, the opening and closing angle of the moving contact disk is 90°, thereby realizing the opening and closing operation of the entire operating mechanism.

[0059] Specifically, as attached Figure 8As shown, the first linkage shaft 18 is provided with a first action surface 181 and a second action surface 182, and the first action surface 181 and the second action surface 182 are arranged at an obtuse angle. In this embodiment, the angle between the two is described by taking 120° as an example. The first action surface 181 and the second action surface 182 are arranged symmetrically, and one end of the first action surface 181 is connected to one end of the second action surface 182 through a first connecting surface 183, where the first connecting surface 183 can be an arc surface or a plane, and the other end of the first action surface 181 is connected to the other end of the second action surface 182 through a second connecting surface 184 to form a closed structure, where 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, and 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, where the third connecting surface 152 is an arc surface.

[0060] The so-called idle 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 action surface 181 or the first action surface 181. It includes the following three states: in the first state, a first idle stroke is provided between the first plane 151 and the second action surface 182; in the second state, a second idle stroke is provided between the first plane 151 and the second action surface 182; in the third state, a third idle stroke is provided between the first plane 151 and the first action surface 181. In this embodiment, the rotation angles of the first idle stroke, the second idle stroke, and the third idle stroke are equal. The cooperation between the first plane 151 and the first action surface 181 and the second action surface 182 forms the effect of the idle stroke, and different idle stroke rotation effects correspond to different states. In addition, the shaft and the waist-shaped hole can also be used to cooperate to 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 is the idle stroke.

[0061] Specifically, as attached Figure 2-Figure 7 As shown, the linkage assembly 13 includes a second linkage shaft 20 and a linkage member 16, a first linkage shaft 18 is arranged on the lever 12, and the second linkage shaft 20 is linked with the linkage member 16. When the second linkage shaft 20 rotates, the linkage member 16 rotates synchronously. The first cavity 15 is arranged at the end of the second linkage shaft 20 facing the lever 12, that is, the lower end of the second linkage shaft 20 is provided with the first cavity 15. The upper end of the second linkage shaft 20 is linked with the knob 11, that is, when the knob 11 rotates, the second linkage shaft 20 rotates accordingly, and then after the idle stroke, the second linkage shaft 20 drives the first linkage shaft 18 to rotate, thereby realizing the cooperation between the knob 11 and the lever 12. The driving part 131 is arranged on the linkage member 16, and the driving part 131 here has a cam-like effect. The cooperation between the second linkage shaft 20 and the linkage member 16 can better realize the linkage effect.

[0062] Specifically, as attached Figure 7 As shown, the linkage 16 includes a first component 161, a second component 162 and a plurality of pins 163. The first component 161 and the second component 162 are arranged in parallel. The pin 163 connects the first component 161 and the second component 162, and the pin 163 forms a fixing effect of 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 the first leg 164 is also fixed with a pin 163. The pin 163 located on the first leg 164 is the driving part 131, that is, the pin 163 located on the first leg 164 is matched with the energy storage component 14. The linkage 16 is increased in strength and contact area by the upper and lower matching arrangement, so that when the driving part 131 is against the sliding part, it can better play a supporting and offsetting effect to prevent the linkage 16 from being damaged. In addition, the linkage member 16 can also be an integrally formed structure, that is, a cam structure, but it is necessary to ensure that the linkage member 16 has a certain strength and height. In this embodiment, the connection is formed by the cooperation of the upper and lower parts, which is simple to process and low in cost.

[0063] Specifically, as attached Figure 1-Figure 5 As shown, the energy storage assembly 14 also includes a bracket 17, and the sliding member 141 and the elastic member 142. The sliding member 141 slides relative to the bracket 17. Here, the bracket 17 is arranged on the body of the isolating switch, and the bracket 17 is connected and fixed 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 part 131, and the sliding member 141 and the driving part 131 form a critical point during the movement. The mutual cooperation between the sliding member 141, the elastic member 142, and the linkage member 16 forms a cooperation effect between the first linkage shaft 18 and the first cavity 15 during the rotation process. The elastic member 142 plays an effect of energy storage and energy release. 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 and accelerate the rotation. In addition, a positioning guide 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 guide effect. At the same time, the positioning pin 171 cooperates with the positioning hole 1411, which can also reduce the force of the elastic member 142 on the sliding member 141 accordingly.

[0064] Specifically, the sliding member 141 is provided with a through hole 1412, and a protrusion 1413 is provided on the inner wall of the through hole 1412. During the rotation of the linkage assembly 13, the driving member 131 moves along the protrusion 1413, and the elastic member 142 stores energy before reaching the highest point of the protrusion 1413, and releases energy after passing the highest point of the protrusion 1413; when the driving member 131 reaches the highest point of the protrusion 1413, the wall of the first cavity 15 is still not in contact with the first linkage shaft 18. 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 at which the knob 11 passes through the idling stroke, that is, when the knob 11 reaches the critical point, the knob 11 has not yet completed the rotation of the idling stroke, that is, the first linkage shaft 18 and the first cavity 15 have not yet formed a linkage. This structure is simple to process and has good practicality. Here, how the sliding member 141, the elastic member 142, and the linkage member 16 form a critical point can also be achieved through other structures, such as the critical point achieved by a connecting rod structure and a torsion spring, or a spring structure, etc.

[0065] 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.

[0066] 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 second 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 that the knob tripping indication is accurate, 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.

[0067] 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.

[0068] Specifically, as attached Figure 2-Figure 5 As shown, the overall working principle is that the first state is the closing position, at which the first plane 151 and the first action surface 181 are against each other, and the first plane 151 and the second action surface 182 form a first idle stroke, and the angle of the first idle stroke is 60°. When the tripping occurs, the elastic component of the second transmission unit 102 acts to rotate the lever 12 (equivalent to the rotation of the first linkage shaft 18), and 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. In this embodiment, when the tripping occurs, the rotation angle of the lever 12 is 10° for example, at which time the second linkage shaft 20 will also rotate 10°, so that the first plane 151 and the first action surface 181 fit and abut against each other, and the first plane 151 and the second action surface 182 form a second idle stroke, and the angle of the second idle stroke is 60°, thereby ensuring that the idle stroke is also 60° in the tripping position, and this position is the second state. To operate from the tripping position to the re-engaging position, the knob 11 needs to be rotated 80°. Rotating the knob 11 causes the second linkage shaft 20 to rotate. When passing the critical point, there is still a 25° idle stroke between the first plane 151 and the second action surface 182. The knob 11 is continued to be rotated. At this time, under the action of the elastic member 142, the re-engaging operation is accelerated, causing the first linkage shaft 18 to rotate, realizing the rotation of the lever 12, and finally realizing the re-engaging operation. In this embodiment, the opening and closing angle of the lever 12 is taken as 30°. Since the lever 12 rotates 10° during the tripping process, the lever 12 rotates 20° from the tripping position to the re-engaging position, and the entire lever 12 also rotates 30°. At this time, the re-engaging position is the third state.

[0069] In the third state, the first plane 151 and the second action surface 182 are against each other, and the first plane 151 and the first action surface 181 form a third idle stroke, and the angle of the third idle stroke is also 60°. From the button position to the closing position, the angle of the knob 11 is 90°, and the critical point is located at the 45° position of the rotation angle of the knob 11. Therefore, the knob 11 rotates 45° and reaches the critical point. At this time, there is still an idle stroke of 15°. After crossing the critical point, under the action of the elastic member 142, the closing operation is accelerated, so that the first linkage shaft 18 rotates, the lever 12 rotates, and finally the closing operation is realized.

[0070] Specifically, as attached Fig. 9 As shown, the connecting rod assembly 21 includes an upper connecting rod and a lower connecting rod. The elastic assembly 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 assembly 26 to rotate.

[0071] Specifically, the rotation axis of the knob 11 and the rotation axis of the lever 12 may be coaxially arranged or may be different axes.

[0072] Specifically, as attached Fig.11 As shown, the lever 12 is a U-shaped structure, and 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 welded or otherwise fixed to form a linkage between the two. This structure forms a linkage effect of a 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, in which the connecting rod assembly 21, the elastic assembly, and the output assembly 26 are all accommodated. After the first linkage shaft 18 is externalized, the output assembly 26 can adjust the relevant structure according to actual needs. At this time, the rotation axis of the output assembly 26 can be coaxial with the rotation axis of the moving contact plate, or it can be non-coaxial. When the rotation axis of the output assembly 26 is not coaxial with the first linkage shaft 18, a transmission structure can be used to form a transmission between the two. Here, the transmission structure can be a connecting member 27, and the connecting member 27 connects the two, or a gear structure can be used to form a transmission.

[0073] Specifically, as attached Figure 12-16As shown, the lever 12 is a U-shaped structure, the first linkage shaft 18 is linked with the lever 12, and the first linkage shaft 18 passes through the two side arms of the lever 12. Here, the first linkage shaft 18 and the lever 12 are welded or otherwise fixed to form a linkage between the two. The first linkage shaft 18 adopts a penetration method to improve the linkage effect of the lever 12. It should be noted here that when the first linkage shaft 18 adopts a penetration method, the first linkage shaft 18 will interfere with the chamber inside the U-shaped lever 12, thereby affecting the overall layout. Specifically, after the first linkage shaft 18 is penetrated, the first linkage shaft 18 is connected and matched with the starting end of the connecting rod assembly 21, and the output assembly 26 is matched with the end of the connecting rod assembly 21. There is no direct contact between the starting end and the end, and the two are transmitted through a number of connecting rods to form an indirect transmission, so the first linkage shaft 18 will affect the layout of the output assembly 26. In this embodiment, the output component 26 is sleeved on the first linkage shaft 18, and the output component 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 component 26 to rotate, and when the output component 26 rotates, it will not drive the first linkage shaft 18 to rotate. The specific structure here can be that the output component 26 is provided with a rotation hole 261, and the cross-sectional size of the rotation hole 261 is larger than the cross-sectional size of the first linkage shaft 18. For example, the cross-section of the rotation hole 261 is circular, and the cross-section of the first linkage shaft 18 is runway-shaped or square. Alternatively, the cross-sections of both can be circular, and it is only necessary to ensure that there is no direct interference between the two during the rotation process. The other end of the output component 26 passes through the side arm of the lever 12 close to the moving contact disk, so that the other end of the output component 26 cooperates with the moving contact disk. In addition, as shown in the attached Figure 12-13 As shown, the output assembly 26 can also be a shaft structure, and 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 different, and those skilled in the art can adjust according to actual needs.

[0074] Specifically, as attached Figure 17-Figure 19As shown, the first linkage shaft 18 passes through the two side arms of the lever 12. The first linkage shaft 18 and the output assembly 26 do not intersect, that is, in order to give the first linkage shaft 18 enough space, 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 set on the same axis. Therefore, at this time, it is necessary to form a transmission between the output assembly 26 and the moving contact plate through a transmission structure. Here, the transmission structure can be a connecting member 27, and the connecting member 27 connects the two. It can also form a transmission through a gear structure. In addition, other transmission methods can also be used 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 actual conditions. It only needs to ensure that it is finally coordinated with the moving contact plate to form a linkage. In this embodiment, the rotation axis of the first linkage shaft 18 and the rotation axis of the moving contact plate can be set on the same axis or on different axes.

The body 22 and the cover plate 24 form a chamber, and the operating mechanism is accommodated in this chamber.
