[0045] The following is a further description of the specific implementation of the switch device of the present invention in conjunction with the embodiments given in the accompanying drawings. The switch device of the present invention is not limited to the description of the following embodiments.

[0048] Furthermore, the operating mechanism o is arranged side by side and connected with the switch body b along the axial direction of the rotating shaft of the moving contact mechanism b-10.

[0049] Furthermore, in the switch body b, the number of switch units b-1 is ≥2, and the switch units b-1 are stacked together axially along the rotation axis of the moving contact mechanism b-10.

[0050] like Figure 1-3 As shown, the operating mechanism o includes a shell 1 and a main body and a transfer shaft 10 respectively arranged in the shell 1. The transfer shaft 10 is rotatably arranged in the shell 1. The transfer shaft 10 is arranged between the rotating shaft 12 and the moving contact mechanism b-10. The transfer shaft 10 is located on one side of the main body in its axial direction (that is, the rotation axis of the transfer shaft 10) and is used to be coaxially arranged with the moving contact mechanism b-10 and connected in transmission. The main body is connected in transmission to the transfer shaft 10 to drive the transfer shaft 10 to rotate reciprocatingly, and the transfer shaft 10 drives the moving contact mechanism b-10 to rotate so that it closes and disconnects with the corresponding static contact.

[0051] like Figure 6-9 As shown, the main body includes a bracket 13, a connecting rod structure, a driving shaft 2 and a rotating shaft 12 respectively rotatably arranged on the bracket 13, a transmission structure 15, and a linkage rod 3 arranged on the rotating shaft 12 and parallel to the rotating axis of the transfer shaft 10 (that is, the linkage rod 3 and the transfer shaft 10 are not coaxially arranged, and the axis of the linkage rod 3 is parallel to the rotating axis of the transfer shaft 10 and is spaced apart); the driving shaft 2 is sequentially connected to the rotating shaft 12 through the transmission structure 15 and the connecting rod structure to drive the rotating shaft 12 to reciprocate, that is, the driving shaft 2, the transmission structure 15, the connecting rod structure and the rotating shaft 12 are sequentially connected to each other, and the rotating shaft 12 is connected to the transfer shaft 10 through the linkage rod 3 to drive the transfer shaft 10 to reciprocate. Further, the driving shaft 2, the rotating shaft 12 and the transfer shaft 10 are coaxially arranged to rotate, which improves the compactness of the layout of the operating mechanism o and reduces the space requirement of the operating mechanism o.

[0052] like Figure 6-9As shown, the connecting rod structure includes a rocker arm 8, a first connecting rod 9, a main spring 14, a jumper 4, a locker 5, a second connecting rod 11 and a stopper arranged on the first connecting rod 9, the rocker arm 8, the jumper 4 and the locker 5 are respectively rotatably arranged on the bracket 13, the drive shaft 2 is connected to the rocker arm 8 through the transmission structure 15 to drive the rocker arm 8 to swing back and forth, the jumper 4 and the locker 5 are snap-fitted, the first connecting rod 9 is rotatably connected to the jumper 4, the second connecting rod 11 is rotatably connected to the first connecting rod 9 and the rotating shaft 12 respectively, one end of the main spring 14 is connected to the rocker arm 8 and the other end is connected to the first connecting rod 9 and the second connecting rod. The rotating connection 11 provides energy for the opening and closing of the operating mechanism o, and the stop part cooperates with the tripping member 4 to prevent the first connecting rod 9 from continuing to rotate when the operating mechanism o is opened and tripped (specifically, the tripping member 4 is rotatably arranged on the bracket 13 through the tripping shaft 4s, and the tripping shaft 4s is preferably the stop part. When the operating mechanism o is opened and tripped, the first connecting rod 9 abuts against the tripping shaft 4s to prevent the first connecting rod 9 from continuing to rotate); the rocker arm 8 is also used to drive the tripping member 4 and the locking member 5 to resume the snap fit; when the operating mechanism o is in the tripped state, the tripping member 4 presses the locking member 5 to prevent it from resetting. Furthermore, the connecting rod structure further comprises a refastener 6 and a reset spring 7, the refastener 6 being rotatably arranged on the bracket 13 and being limitedly matched with the lock fastener 5; when the operating mechanism o is normally closed and opened, that is, the drive shaft 2 is driven to rotate by an external force (for example, the operator manually drives the drive shaft 2 to rotate through the handle 16 or drives the drive shaft 2 to rotate through the electric mechanism), when the operating mechanism o is closed and opened, the lock fastener 5 maintains a snap fit with the jump fastener 4 and maintains a snap fit with the refastener 6. The first limit fit; the refastener 6 is driven by an external force to rotate, releasing the first limit fit with the lock member 5, the lock member 5 rotates to release the snap fit with the lock member 4 to disengage the operating mechanism, and the refastener 6 and the lock member 5 establish a second limit fit; the reset spring 7 cooperates with the lock member 5 and the refastener 6 respectively, and applies a reset force to the lock member 5 and the refastener 6 respectively, that is, the reset spring 7 applies a force to the lock member 5 and the refastener 6 to reset the lock member 5 and the refastener 6 respectively. Further, as Figure 6 , Fig.10 As shown, when the refastener 6 establishes the first limit fit with the lock fastener 5, the cross arm 6-1 of the refastener 6 abuts against the side of the lock fastener 5 facing the refastener 6 (specifically, the lock fastener 5 includes a lock fastener body 5-0, the lock fastener body 5-0 is snap-fitted with the lock fastener 4, and the free end of the cross arm 6-1 abuts against the side of the lock fastener matching end of the lock fastener body 5-0 of the lock fastener 5 facing the refastener 6, so that the lock fastener 5 and the jump fastener 4 maintain snap-fitting); as shown Figure 8-9As shown, when the re-fastener 6 establishes the second limiting cooperation with the locking member 5, the vertical arm 6-0 of the re-fastener 6 is opposite to the locking member 5, and the horizontal arm 6-1 of the re-fastener 6 abuts against one end of the locking member body 5-0 of the locking member 5 (specifically, the limiting surface 6-100 of the horizontal arm 6-1 abuts against the end of the locking member matching end of the locking member body 5-0), preventing the re-fastener 6 from resetting.

[0053] Specifically, Figure 6 As shown, one end of the jumper 4 is rotatably arranged on the bracket 13 and the other end is snap-fitted with the lock member 5, one end of the first connecting rod 9 is rotatably connected to the middle part of the jumper 4 and the other end is rotatably connected to one end of the second connecting rod 11, the other end of the second connecting rod 11 is rotatably connected to one end of the rotating shaft 12, the middle part of the rotating shaft 12 is rotatably arranged on the bracket 13, and the other end of the rotating shaft 12 is provided with a linkage rod 3. Further, the first connecting rod 9 and the second connecting rod 11 are rotatably connected through a connecting rod hinge shaft, one end of the main spring 14 is connected to the rocker arm connecting plate of the rocker arm 8 and the other end is connected to the connecting rod hinge shaft.

[0054] like Figure 7-9 As shown, the lock member 5 includes a lock member long arm 5-1, and when the operating mechanism o is in the tripped state, the jumper 4 abuts against the lock member long arm 5-1 to prevent the lock member 5 from resetting, that is, the lock member 5 is kept in a static state under the joint action of the reset spring 7 and the jumper 4. Further, one end of the lock member long arm 5-1 is connected to the lock member body 5-0 of the lock member 5, and the other end cooperates with the jumper 4.

[0055] like Figure 1 , 3As shown in FIG. 6 , the bracket 13 includes an upper side plate 13-1 and a lower side plate 13-2 that are relatively spaced apart, and the jump fastener 4, the lock fastener 5, the refastener 6, the return spring 7, the first connecting rod 9, the second connecting rod 11, the rotating shaft 12 and the main spring 14 are all arranged between the upper side plate 13-1 and the lower side plate 13-2; the rocker arm 8 includes a rocker arm leg and a rocker arm connecting plate, the two rocker arm legs are opposite and are respectively connected to the two ends of the rocker arm connecting plate by bending, and the free ends of the two rocker arm legs are respectively rotatably arranged on the upper side plate 13-1 and the lower side plate 13-2. Furthermore, the operating mechanism o also includes an auxiliary spring 17 acting on the jumper 4. After the lock member 5 and the jumper 4 are released from the snap fit, the main spring 14 and the auxiliary spring 17 both apply a force to the jumper 4. Both forces cause the jumper 4 to rotate in the same direction. The jumper 4 rotates along the tripping direction and away from the lock member 5 and rotates to the tripping position (when the jumper 4 is in the tripping position, it is limited by the jumper limit shaft 18 set on the bracket 13 to stop the jumper 4 in the tripping position). Under the action of the main spring 14, the rocker arm 8 is limited by the jumper 4 and remains relatively still. The main spring 14 and the auxiliary spring 17 cooperate to significantly improve the disintegration speed and tripping speed of the operating mechanism o, reduce the action time of the operating mechanism o, and both the main spring 14 and the auxiliary spring 17 can drive the moving contact mechanism b-10 to rotate to the disconnected position through the jumper 4, the first connecting rod 9 and the second connecting rod 11, which is beneficial to improve the breaking efficiency of the moving contact mechanism b-10 and the static contact, and improve the breaking capacity of the switch. Further, the middle part of the jumper 4 is rotatably arranged on the bracket 13, one end is snap-fitted with the lock member 5, and the other end is connected to the auxiliary spring 17. Further, the bracket 13 is provided with a bracket hanging spring part, the jumper 4 is provided with a jumper hanging spring part, and the two ends of the auxiliary spring 17 are respectively connected to the bracket hanging spring part and the jumper hanging spring part.

[0056] Specifically, Figure 3 , 6 In the direction shown, an installation space is formed between the upper side plate 13-1 and the lower side plate 13-2 of the bracket 13, and the jumper 4, the main spring 14, the first connecting rod 9, the second connecting rod 11, the lock 5, the re-lock 6, the reset spring 7, and the rotating shaft 12 are all located in the installation space; in the first direction of the installation space, the two ends of the installation space are respectively the first end and the second end, the rocker arm connecting plate of the rocker arm 8 is located outside the first end, and the rotating shaft 12 is located inside the second end; in the second direction of the installation space, the two ends of the installation space are respectively the third end and the fourth end, the lock 5 and the re-lock 6 are located inside the third end, the auxiliary spring 17 is located inside the fourth end, and the jumper 4 extends from the third end to the fourth end; the first direction and the second direction of the installation space are both parallel to the upper side plate 13-1 and the lower side plate 13-2, and the first direction and the second direction of the installation space intersect. The layout of the operating mechanism o is reasonable, which is conducive to reducing the required installation space.

[0057] like Figure 3 , 7 -9, the transmission structure 15 includes a crank 15-0 and a transmission connecting rod 15-1, the crank 15-0 is fixedly arranged on the drive shaft 2 and rotates synchronously therewith, one end of the transmission connecting rod 15-1 is rotationally connected to the crank 15-0 and the other end is rotationally connected to the rotating shaft rocker arm 8. Further, the operating mechanism o includes two sets of transmission structures 15, the two sets of transmission structures 15 are arranged on both sides of the upper side plate 13-1 and the lower side plate 13-2, and the drive shaft 2 is transmission-connected to the two rocker legs of the rocker arm 8 through the two sets of transmission structures 15.

[0058] It should be pointed out that the transmission structure 15 is not limited to the above-mentioned implementation method. The transmission structure 15 can also be implemented by existing technical means such as gear transmission, which will not be listed here.

[0059] like Figure 3 , 6 As shown in FIGS. 10-11, the refastener 6 also includes a travel limit shaft 6-2 arranged on the vertical arm 6-0, and the bracket 13 is provided with a travel limit hole, and the travel limit shaft 6-2 is movably inserted in the travel limit hole to limit the rotation stroke of the refastener 6. Further, the refastener 6 includes two travel limit shafts 6-2 respectively arranged on both sides of the vertical arm 6-0 (specifically, the two travel limit shafts 6-2 are respectively arranged on both sides of the two vertical arm side plates 6-02 of the vertical arm 6-0), and the upper side plate 13-1 and the lower side plate 13-2 are both provided with travel limit holes, and the two travel limit shafts 6-2 are respectively movably inserted in the two travel limit holes.

[0060] The operating mechanism o has the same working principle and action process as the operating mechanism of the four-link-five-link switching structure in the prior art, and will not be described in detail here.

[0061] like Figure 1-5 As shown, an improvement of the operating mechanism o is:

[0062] The transfer shaft 10 includes a connecting hole 10-0 and an anti-fool structure. One end of the linkage rod 3 is a plug-in end for plugging and matching with the connecting hole 10-0. The plug-in end plugs and matches with the connecting hole 10-0 to realize the transmission connection between the linkage rod 3 and the transfer shaft 10, so that the rotating shaft 12 can drive the transfer shaft 10 to reciprocate through the linkage rod 3; the anti-fool structure is used to abut against the plug-in end of the linkage rod 3 that is not inserted into the connecting hole 10-0, preventing the main body from being installed in place. During assembly, the transfer shaft 10 is installed in the housing 1 before the main body. If the plug-in end is not inserted into the connecting hole 10-0, the plug-in end abuts against the anti-fool structure, preventing the main body from being installed in place, that is, even if the main body cannot be installed in the housing 1 in the correct posture. The anti-fool structure can prevent the linkage rod 3 and the transfer shaft 10 from being installed in place in the housing 1 when they are not assembled correctly, thereby avoiding rework due to incorrect assembly of the main body and the transfer shaft 10, and improving the qualified rate and efficiency of product assembly.

[0063] like Figure 4-5 As shown, the side of the adapter shaft 10 facing the main body is the mating side; the fool-proof structure is a blocking surface arranged on the mating side, that is, when the main body is installed into the shell 1, if the plug-in end of the linkage rod 3 is not inserted into the connecting hole 10-0 of the adapter shaft 10, the plug-in end is pressed against the blocking surface, so that the main body cannot be installed in place, thereby prompting the operator that an incorrect installation has occurred.

[0064] Furthermore, the maximum rotation angle of the adapter shaft 10 is the stroke angle; on the projection perpendicular to the rotation axis of the adapter shaft 10, the blocking surface covers at least two arc areas, one end of each arc area is connected to the connecting hole 10-0, the center of each arc area coincides with the rotation center of the adapter shaft 10, the center angle of each arc area is half of the stroke angle, and the two arc areas are symmetrically distributed with the center of the connecting hole 10-0 and the rotation center line of the adapter shaft 10 as the symmetry axis.

[0065] Specifically, Figure 5As shown, the adapter shaft 10 includes an adapter shaft main board 10m and an adapter shaft extension plate, the adapter shaft extension plate is arranged around the circumferential side of the adapter shaft main board 10m, and the central angle of the adapter shaft extension plate is less than 360°, that is, the adapter shaft extension plate is an arc-shaped plate arranged around the circumferential side of the adapter shaft 10m; on the projection perpendicular to the rotation axis of the adapter shaft 10, the outer edges of the two arc-shaped areas (that is, the side edges of the arc-shaped areas away from the rotation center of the adapter shaft 10) are on the adapter shaft extension plate, and the inner edges of the arc-shaped areas (that is, the side edges of the arc-shaped areas close to the rotation center of the adapter shaft 10) are located on the adapter shaft extension plate (that is, the entire arc-shaped area is located on the adapter shaft extension plate) or on the adapter shaft main board 10m (that is, the arc-shaped areas are located on the adapter shaft extension plate) . The area is arranged along the radial direction of the adapter shaft 10, spanning the adapter shaft main board 10m and the adapter shaft extension plate), and the adapter shaft main board 10m and the adapter shaft extension plate are coplanar on the side facing the main body as the main plane 10-3; the adapter shaft 10 also includes a first boss and a second boss arranged on the main plane 10-3, the first boss and the second boss are arranged along the axial protrusion of the adapter shaft 10, and the connecting hole 10-0 is arranged on the first boss, the table surface of the first boss is the first table surface 10-1, and the table surface of the second boss is the second table surface 10-2, the first table surface 10-1, the second table surface 10-2 and the main plane 10-3 are arranged in parallel in sequence along the axial direction of the adapter shaft 10 and gradually move away from the main body, and the first table surface 10-1 is flush with the entrance end of the connecting hole 10-0. The above structural design not only ensures the structural strength of the outer wall of the connecting hole 10-0 and increases the service life of the transfer shaft 10, but also plays a foolproof role, reduces the amount of materials used, reduces the production cost, and improves the overall structural strength of the transfer shaft 10. During assembly, if the plug-in end of the linkage rod 3 is not inserted into the connecting hole 10-0 of the transfer shaft 10, then as the relative position of the linkage rod 3 and the transfer shaft 10 changes, the plug-in end abuts against the first stop surface 10-1, the second stop surface 10-2, or the third stop surface 10-3.

[0066] As another embodiment, the blocking surface at least covers an annular area as wide as the diameter of the connecting hole 10-0, and the connecting hole 10-0 is located in the annular area in its axial projection, so that no matter how much the transfer shaft 10 rotates, the plug-in end of the linkage rod 3 will abut against the blocking surface as long as it is not inserted into the connecting hole 10-0. Of course, due to the limitations of the structural design of the operating mechanism o, the transfer shaft 10 can only rotate within a certain angle range. Furthermore, the blocking surface covers the entire area of ​​the mating side except the connecting hole 10, which is conducive to reducing the design difficulty of the transfer plate 10.

[0067] Furthermore, the side of the adapter shaft 10 facing away from the main body is plugged into and matched with the moving contact mechanism b-10 of the switch unit adjacent to the operating mechanism o.

[0068] like Figure 1-5As shown, the housing 1 includes an upper cover 1-0, a middle shell 1-1 and a base 1-2 which are sequentially assembled together along the axial direction of the transfer shaft 10, the middle shell 1-1 includes a partition 1-20, the main body is arranged between the upper cover 1-0 and the middle shell 1-1, the transfer shaft 10 is arranged between the middle shell 1-1 and the base 1-2, the main body and the transfer shaft 10 are arranged on both sides of the partition 1-20 respectively, and the plug-in end of the linkage rod 3 passes through the partition 1-20 and is plugged into and matched with the connecting hole 10-0 of the transfer shaft 10. Further, as Figure 1 As shown, the operating mechanism o also includes a handle 16, one end of the drive shaft 2 passes through the upper cover 1-0 and is fixedly connected to the handle 16. When the handle 16 is screwed by external force, the handle 16 drives the drive shaft 2 to rotate, and the drive shaft 2 drives the operating mechanism to close and open the switch. During assembly, if the plug-in end of the linkage rod 3 is not inserted into the connection hole 10-0 of the adapter shaft 10, the plug-in end abuts against the foolproof structure, preventing the main body from being installed in place in the middle shell 1-1, and the upper cover 1-0 cannot be installed correctly, thereby prompting the production personnel that there is an assembly error.

[0069] like Figure 1-2 As shown, the assembly side of the transfer shaft 10 is limitedly matched with the partition 1-20, and the side of the transfer shaft 10 away from the main body is limitedly matched with the bottom plate of the base 1-2 in the form of surface contact, that is, the side of the transfer shaft 10 away from the main body is in surface contact with the bottom plate of the base 1-2, limiting the movement of the transfer shaft 10 along its rotation axis and preventing the transfer shaft 10 from tilting. Further, the first table surface 10-1 of the first boss of the transfer shaft 10 is limitedly matched with the partition 1-20, and the side of the transfer shaft 10 away from the main body is limitedly matched with the bottom plate of the base 1-2, limiting the movement of the transfer shaft 10 along its rotation axis.

[0070] like Figure 1 and 3 As shown, the rotating shaft 12 is rotatably arranged between the upper side plate 13-1 and the lower side plate 13-2; the upper side plate 13-1 is provided with an upper arc hole, and the lower side plate 13-2 is provided with a lower arc hole; the linkage rod 3 includes an upper linkage rod section 3-0, a middle linkage rod section 3-1 and a lower linkage rod section 3-2 which are connected in sequence, the outer diameter of the middle linkage rod section 3-1 is larger than the outer diameter of the upper linkage rod section 3-0 and the lower linkage rod section 3-2 and larger than the width of the lower arc hole, the upper linkage rod section 3-0 is inserted into the rotating shaft 12 and inserted into the arc hole after passing through the rotating shaft 12, the middle linkage shaft section 3-2 is located between the rotating shaft 12 and the lower side plate 13-2, and the lower linkage rod section 3-2 is inserted into the lower arc hole and passes through the lower arc hole to form a plug-in end. The position of the linkage rod 3 in its axial direction and the motion trajectory of the linkage rod 3 are both reliably limited, ensuring the reliable and stable operation of the linkage rod 3 and the reliable connection between the linkage rod 3 and the transfer shaft 10. Furthermore, the outer diameters of the upper section 3-0 of the linkage rod and the lower section 3-2 of the linkage rod are the same, and the upper arc-shaped hole and the lower arc-shaped hole are symmetrical structures to each other.

[0071] like Figure 6-8 As shown, the rotating shaft 12 includes a rotating shaft side plate 12-1 and a rotating shaft connecting plate 12-2. The two rotating shaft side plates 12-1 are arranged at a relative interval and are respectively connected to the rotating shaft connecting plate 12-2 by bending. The middle parts of the two rotating shaft side plates 12-1 are rotatably arranged on the bracket 13, one end is connected to the connecting rod structure by transmission (specifically, connected to the second connecting rod 11 of the connecting rod structure by transmission) and the other end is provided with a linkage rod 13 (specifically, the linkage rod upper section 3-0 of the linkage rod 3 passes through the two rotating shaft side plates 12-1 in sequence). Further, the middle parts of the two rotating shaft side plates 12-1 of the rotating shaft 12 are provided with a rotating shaft hole, and the two rotating shaft side plates 12-1 are sleeved on the driving shaft 2 through their respective rotating shaft holes, that is, the rotating shaft 12 is rotatably arranged around the driving shaft 2; the rotating shaft 12 is preferably formed by cutting and bending a metal plate. The rotating shaft 12 has a simple structure, is easy to manufacture, and has a low production cost.

[0072] like Figure 7-11 As shown, the second improvement of the operating mechanism is:

[0073] like Figure 7-9 As shown, the reset spring 7 is a torsion spring, which is sleeved on a spring shaft fixed on the bracket 13 and is arranged between the lock member 5 and the re-lock member 6; the re-lock member 6 includes a vertical arm 6-0 and a horizontal arm 6-1 connected by bending; the two spring arms of the reset spring 7 cooperate with the lock member 5 and the vertical arm 6-0 respectively, and apply a reset force to the lock member 5 and the re-lock member 6 respectively. Figure 7-8As shown in 10-11, the vertical arm 6-0 includes a spring limiting groove 6-01 arranged on the side thereof facing the locking member 5 and an avoidance notch 6-00 arranged on one side of the spring limiting groove 6-01, and the avoidance notch 6-00 is located on one side of the spring limiting groove 6-01 in the rotation axis direction of the locking member 6; during assembly, the spring arm (hereinafter referred to as the second arm 7-2) that matches the vertical arm 6-0 is moved and enters the spring limiting groove 6-01 through the avoidance notch 6-00, specifically: during assembly, the reset spring 7 First, the spring arm (hereinafter referred to as the first arm 7-1) which is sleeved on the spring shaft and in which the reset spring 7 cooperates with the lock member 5 is placed between the lock member 6 and the lock member 5, and then the second arm 7-2 is moved by an external force, and swings from one side of the vertical arm 6-0 (the side away from the lock member 5) to the other side of the vertical arm 6-0 (the side facing the lock member 5) through the avoidance gap 6-00, and then the second arm is placed in the spring limiting groove 6-01 to complete the assembly of the reset spring 7. During the process of the second arm being moved, the first arm always rests on the lock member 5. When the existing operating mechanism is assembled, one of the two spring arms of the reset spring is close to the lock member body of the lock member, and the other rests in the spring limiting groove of the reset spring. Then the external force overcomes the elastic force of the reset spring and assembles the lock member on the bracket; the reset spring is installed in the bracket in the energy storage state, which is easy to cause the reset member and the lock member to tilt, and correction is required after assembly, which affects the assembly efficiency. When the operating mechanism of the present invention is assembled, the structural design of the avoidance notch 6-00 and the spring limit groove 6-01 of the fastener 6 allows the operating mechanism o to first complete the assembly of the locking member 5, the fastener 6, the reset spring 7 and the spring shaft with the bracket 13 during the assembly process. After the upper side plate 13-1 and the lower side plate 13-2 of the bracket 13 are fixed to each other (for example, the upper side plate 13-1 and the lower side plate 13-2 are fixed together by a connecting shaft), the assembly between the reset spring 7 and the fastener 6 is then completed, thereby simplifying the assembly operation, reducing the difficulty of assembling the reset spring 7, and improving the assembly efficiency.

[0074] like Figure 6 As shown, the reset spring 7 makes the locking member 5 and the re-locking member 6 have a tendency to rotate in the same direction. Figure 6In the direction shown, the reset spring 7 makes the lock member 5 and the re-fastening member 6 have a tendency to rotate in the clockwise direction. Further, the two ends of the lock member body 5-0 of the lock member 5 are respectively the lock member pivot end and the lock member mating end, and the lock member body 5-0 is rotatably arranged on the bracket 13 through the lock member pivot end; the horizontal arm 6-1 of the re-fastening member 6 is opposite to the lock member mating end, and the free end of the vertical arm 6-0 (that is, the end of the vertical arm 6-0 away from the horizontal arm 6-1) is opposite to the lock member pivot end; one of the two spring arms of the reset spring 7 is mated with the lock member mating end, and the other is mated with the free end of the vertical arm 6-0, so that the lock member 5 and the re-fastening member 6 have a tendency to rotate in the same direction.

[0075] like Figure 6 As shown, the locking member 5 is rotatably arranged on the bracket 13 via a locking shaft 5s, and both ends of the locking shaft 5s are respectively arranged on the upper side plate 13-1 and the lower side plate 13-2 of the bracket 13. The locking shaft 5s serves as a spring shaft, which is beneficial to reducing the number of components of the operating mechanism o.

[0076] As another example, Fig.12 and 13 As shown, the reset spring 7 is a torsion spring, the lock member 5 includes a spring support arm 5-3 arranged on the lock member body 5-0, the reset spring 7 is sleeved on the spring support arm 5-3, one spring arm cooperates with the lock member 5, and the other spring arm cooperates with the refastener 6. Further, the lock member 5 also includes a lock member support finger 5-2, two lock member support fingers 5-2 are respectively arranged on the two ends of the upper side plate 13-1 and the lower side plate 13-2 of the lock member body 5-0 respectively close to the bracket 13, the two lock member support fingers 5-2 are respectively rotatably arranged on the upper side plate 13-1 and the lower side plate 13-2, the upper side plate 13-1 and the lower side plate 13-2 are preferably respectively provided with a lock member shaft hole, and the two lock member support fingers 5-2 are respectively rotatably inserted into the two lock member shaft holes. Furthermore, the lock body 5-0 includes a lock main board 5-00 and a lock side plate 5-01, the two lock side plates 5-01 are opposite and are respectively connected to the two ends of the lock main board 5-00 by bending, the two lock support fingers 5-2 are respectively arranged on the two lock side plates 5-01, one end of the spring support arm 5-3 is connected to one lock side plate 5-01 by bending and is opposite to the lock main board 5-00 side by side, and one end of the lock long arm 5-1 is connected to the lock main board 5-00 by bending. As a variation of the above embodiment, the lock 5 can also be provided without the lock support finger 5-2, but the two lock side plates 5-01 are rotatably arranged on the bracket 13 through the lock shaft 5s, and the lock shaft 5s passes through the two lock side plates 5-01 and the two ends are respectively arranged on the upper side plate 13-1 and the lower side plate 13-2.

[0077] It should also be pointed out that the reset spring 7 is not limited to a torsion spring, and it can be arranged on the bracket 13 or the locking member 5, as long as it has two spring arms that respectively cooperate with the locking member 5 and the re-fastening member 6, and respectively apply forces to the locking member 5 and the re-fastening member 6 so that the two have a tendency to rotate in the same direction; for example, the reset spring 7 is a V-shaped spring sheet, whose bending part is arranged on the bracket 13 or the locking member 5, and its two spring arms respectively cooperate with the locking member 5 and the re-fastening member 6.

[0078] like Figure 10-11 As shown, in the fastener 6, one end of the vertical arm 6-0 is connected to the horizontal arm 6-1 by bending, and the other end is provided with a spring limit groove 6-01 on the side facing the lock fastener 5, and the bending connection between the vertical arm 6-0 and the horizontal arm 6-1 is rotatably set on the bracket 13. Further, the vertical arm 6-0 includes a vertical arm main board 6-02, a vertical arm side plate 6-03 and a vertical arm reinforcing rib 6-04, two vertical arm side plates 6-03 are arranged side by side and are respectively connected to the vertical arm main board 6-02 by bending, the two vertical arm side plates 6-03 are preferably connected to both ends of the vertical arm main board 6-02 by bending, and the overall cross section is a U-shaped structure, one end of the vertical arm main board 6-02 and the vertical arm side plate 6-03 are respectively connected to one side of the horizontal arm 6-1, and the vertical arm side plate 6-03 It is preferably connected to the two ends of the horizontal arm 6-1 by bending and forming an overall U-shaped structure, the vertical arm reinforcement rib 6-04 is arranged in the middle of the vertical arm main plate 6-02 and between the two vertical arm side plates 6-03, the two ends of the vertical arm reinforcement rib 6-04 are respectively connected to the two vertical arm side plates 6-03 and are parallel to the horizontal arm 6-1, the spring limit groove 6-10 is arranged close to one vertical arm side plate 6-03, and the spring limit groove 6-10 and the horizontal arm 6-1 are respectively located on both sides of the vertical arm reinforcement rib 6-04. The refastener 6 is an overall frame-type structure with simple structure and high strength, and the overall quality is light, saving production materials and costs.

[0079] like Figure 6 As shown, the refastening member 6 is rotatably arranged on the bracket 13 via the refastening shaft 6s, and the two ends of the refastening shaft 6s are respectively arranged on the upper side plate 13-1 and the lower side plate 13-2 of the bracket 13. Further, the end of the vertical arm side plate 6-03 connected to the horizontal arm 6-1 is provided with a refastening shaft hole for the refastening shaft 6s to pass through.

[0080] like Figure 7-11As shown, the refastener 6 also includes a limiting surface 6-100 set on the horizontal arm 6-1, and the lock 5 is rotatably set on the bracket 13 through the lock body 5-0; when the operating mechanism o is in the disengaged state, the limiting surface 6-100 abuts against one end of the lock body 5-0 to prevent the refastener 6 from resetting, that is, to prevent the refastener 6 from rotating under the action of the reset spring 7, and the refastener 6 and the lock 5 remain in the second limiting matching state and cannot be switched to the second limiting matching state. Further, the refastener 6 includes a limiting boss 6-10 set on the horizontal arm 6-1, and the side of the limiting boss 6-10 facing the vertical arm 6-0 is the limiting surface 6-100.

[0081] Furthermore, when the operating mechanism o is in the released state, the limiting surface 6-100 is in line contact or surface contact with one end of the locking member body 5-0. Fig. 9 As shown, when the operating mechanism o is in the released state, the limiting surface 6-100 is in line contact with the end of the locking member mating end of the locking member body 5-0.

[0082] like Fig. 9 As shown, the third improvement of the operating mechanism o is:

[0083] like Fig. 9 As shown, the angle α between the center line of the vertical arm 6-0 of the refastener 6 and the limit surface 6-100 is greater than 90°, thereby ensuring that when the operating mechanism o is refastened, the locking member 5 can be smoothly separated from the limit surface 6-100 and reset, avoiding the deadlock between the refastener 6 and the locking member 5, which would cause the operating mechanism o to fail.

[0084] The following is a second embodiment of the switch device of the present invention. The switch device of the second embodiment is preferably a circuit breaker. The difference between the switch device of the second embodiment and the switch device of the first embodiment is that:

[0085] The operating mechanism o is not provided with a drive shaft 2, a handle 16 and a transmission structure 15, and an external force directly drives the rocker arm 8 to swing and drives the operating mechanism o to close and open. In the switch electrical appliance of this embodiment, the normal opening and closing of the operating mechanism o refers to the operator manually driving the rocker arm 8 to swing (or driving the rocker arm 8 to swing through an electric mechanism) to close and open the operating mechanism o. Furthermore, the operating mechanism o may also not be provided with a transfer shaft 10, and the linkage rod 3 is directly connected to the moving contact mechanism b-10 (for example, the linkage rod 3 is directly plugged into the contact support of the moving contact mechanism b-10) to drive the moving contact mechanism b-10 to rotate. Furthermore, the operating mechanism o may also not be provided with the rotating shaft 12 and the linkage rod 3. The end of the second linkage rod 11 that is transmission-connected to the rotating shaft 12 is transmission-connected to the moving contact mechanism b-10 through a linkage shaft similar to the linkage rod 3. For example, the bracket 13 is provided with an arc-shaped hole for guiding the motion trajectory of the linkage shaft (similar to the upper arc-shaped hole and the lower arc-shaped hole that cooperate with the linkage rod 3). One end of the linkage shaft is plug-fitted with the contact support of the moving contact mechanism b-10 to drive the moving contact mechanism b-10 to rotate.

[0086] It should be noted that in the description of the present invention, the terms "upper", "lower", "left", "right", "inner", "outer", etc. indicate directions or positional relationships based on directions or positional relationships shown in the accompanying drawings, or directions or positional relationships that are usually placed when in use, and are only for the convenience of description, rather than indicating that the device or element referred to must have a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", "third", etc. are only used to distinguish descriptions, and cannot be understood as indicating relative importance.

[0087] The above contents are further detailed descriptions of the present invention in combination with specific preferred embodiments, and it cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the protection scope of the present invention.
