The operating mechanism of the switch device and the switch device of the utility model are not limited to the description of the following embodiments.

[0031] like Figure 1 As shown, the switch device of this embodiment is a disconnector, including an operating mechanism and at least one conductive unit (not shown in the figure), the operating mechanism and the conductive unit are stacked, the operating mechanism is connected to the conductive unit to drive the conductive unit to conduct or disconnect, the conductive unit includes a conductive unit housing and a contact system and an arc extinguishing system arranged in the conductive unit housing and used in conjunction, the contact system includes a moving contact mechanism pivotally arranged on the conductive device housing and a static contact coordinated with the moving contact mechanism, the rotating disk 1 of the operating mechanism is connected to the moving contact mechanism to drive it to rotate, so that the moving contact mechanism and the static contact are closed or disconnected, the moving contact mechanisms of adjacent conductive units are connected in a driving manner, and the conductive unit is used to control the power supply to the load.

The disconnector of this embodiment may also include an external auxiliary device arranged outside the housing of the operating mechanism, which is used to feedback the state of the disconnector, or perform signal control. Of course, the switch device of this embodiment may also be a circuit breaker, etc.

[0032] like Figure 1-3As shown, the operating mechanism of the switch device of this embodiment includes a housing, a main shaft 3, a connecting rod 2 and a turntable 1 which are respectively arranged in the housing, one end of the main shaft 3 drives the connecting rod 2 to rotate through an energy storage mechanism to drive the turntable 1 to perform the opening and closing operation of the switch device, and the other end of the main shaft 3 extends out of the housing for operation. The turntable 1 has an eccentrically arranged turntable passive part 11, and the connecting rod 2 includes a connecting rod driving part 21 drivingly matched with the turntable passive part 11. When the main shaft 3 drives the connecting rod 2 to rotate through the energy storage mechanism, the connecting rod driving part 21 acts on the turntable passive part 11 to drive the turntable 1 to rotate to perform the opening and closing operation. In the operating mechanism of the switch device and the switch device of this embodiment, the connecting rod driving part 21 drives and cooperates with the eccentrically arranged turntable passive part 11 to realize the drive between the connecting rod 2 and the turntable 1, so that the connecting rod driving part 21 can drive the turntable passive part 11 in the simplest way, such as direct contact, simplifying the structure of the connecting rod 2 and the turntable 1, with low precision requirements, facilitating production and assembly, and reducing production costs.

[0033] like Figure 2-3 As shown, in the driving structure between the connecting rod 2 and the turntable 1 of this embodiment, the connecting rod driving part 21 is a notch structure with two opposite driving side walls, and the turntable driven part 11 is a convex structure, which is placed between the two driving side walls of the connecting rod driving part 21. When the driving side wall of the connecting rod 2 contacts the turntable driven part 11 of the turntable 1, the connecting rod 2 drives and cooperates with the turntable 1. The driving side wall of the connecting rod 2 not only drives the turntable 1, but also stops the turntable 1 from rotating when the turntable 1 can rotate relative to the connecting rod 2.

[0034] Usually, the rotation angle of the turntable 1 is equal to the rotation angle of the connecting rod 2. Preferably, in this embodiment, the rotation angle of the turntable 1 is greater than the rotation angle of the connecting rod 2. After the connecting rod 2 drives the turntable 1 to rotate, when the driving side wall of the connecting rod 2 is not in contact with the turntable driven part 11 of the turntable 1, the turntable 1 can continue to rotate relative to the connecting rod 2, so that the rotation stroke of the turntable 1 is greater than the rotation stroke of the connecting rod 2, that is, the distance between the two driving side walls of the connecting rod 2 is relatively larger, greater than the width of the protruding structure, so that the rotation angle of the turntable 1 can be greater than the rotation angle of the connecting rod 2, and the opening distance of the moving contact driven by the turntable 1 can be expanded.

[0035] like Figure 2-3As shown, a specific embodiment of the driving structure between the connecting rod 2 and the turntable 1 of this embodiment, the axis of the connecting rod 2 is perpendicular to the axis of the turntable 1, the connecting rod driving part 21 is arranged along the radial direction of the connecting rod 2, and the turntable driven part 11 is arranged along the axial direction of the turntable 1. Preferably, the connecting rod 2 includes a connecting rod lug 22 formed by radial protrusions, the connecting rod lug 22 is provided with the connecting rod driving part 21 with a notch structure, the turntable driven part 11 is a raised truncated cone structure, the turntable driven part 11 is placed in the connecting rod driving part 21, and the connecting rod 2 drives the turntable driven part 11 through the connecting rod driving part 21 to drive the turntable 1 to rotate, while the turntable driven part 11 slides in the notch structure of the connecting rod driving part 21. In this embodiment, the driving between the connecting rod 2 and the turntable 1 is realized by the cooperation of the notch and the truncated cone, the structure is simple, and the truncated cone is limited in the notch, so that the driving action between the connecting rod 2 and the turntable 1 is reliable and stable. Of course, as other embodiments, the connecting rod 2 and the turntable 1 of this embodiment can also be driven by shaft-hole matching, or by relatively arranged protrusions and driving surfaces on the protrusions.

[0036] like Figure 1 and Figure 4 As shown, the structure of the turntable 1 of this embodiment is that the inner end of the turntable 1 is rotatably mounted in the housing, the inner end of the turntable 1 is provided with the turntable driven part 11, and the outer end of the turntable 1 is passed through the turntable hole 51 ( Figure 8 ) extends out of the housing, the outer end of the rotating disk 1 is used to be connected to the moving contact mechanism of the conductive unit to drive the moving contact mechanism to rotate to close or disconnect with the static contact, and the outer end of the rotating disk 1 is provided with a transmission groove 12 for connecting with the moving contact mechanism. Specifically, the inner end of the rotating disk 1 is provided with a circle of rotating disk flange 13 in the radial direction, and the side wall of the housing is provided with two symmetrical rotation grooves 52 ( Figure 7 ), the two side edges of the turntable flange 13 are rotatably inserted into the rotation groove 52.

[0037] like Figure 2-3As shown, the driving relationship between the main shaft 3 and the connecting rod 2 of this embodiment is that the axis of the main shaft 3 coincides with the axis of the connecting rod 2, and the main shaft 3 rotates around the axis of the main shaft 3 to switch between the first position, the middle position and the second position; the connecting rod 2 rotates around the axis of the connecting rod 2 to switch between the third position and the fourth position; when closing the switch, the main shaft 3 is in the first position and the connecting rod 2 is in the third position; when opening the switch, the main shaft 3 is in the second position and the connecting rod 2 is in the fourth position; the main shaft 3 is driven by an external force to rotate toward the middle position so that the energy storage mechanism stores energy and the connecting rod 2 remains stationary, after the main shaft 3 rotates through the middle position (i.e., the dead point position of the energy storage mechanism), the energy storage mechanism releases energy and drives the main shaft 3 and the connecting rod 2 to rotate in opposite directions respectively, so that the connecting rod 2 can switch between the third position and the fourth position, and the main shaft 3 continues to rotate to switch between the first position and the second position. The energy storage mechanism stores energy before the dead point position and releases energy after the dead point position, so that the connecting rod 2 can rotate rapidly at a large angle.

[0038] like Figure 2 , 6 -7, the rotation limiting structure of the main shaft 3 of this embodiment, the main shaft 3 is respectively limited by the housing in the first position and the second position to limit the rotation stroke of the main shaft 3. Specifically, the main shaft 3 includes a main shaft body 31 and a positioning protrusion 32, the positioning protrusion 32 is arranged on the radial side wall of the main shaft body 31, the housing is provided with a housing main shaft hole 53, the main shaft body 31 is rotatably inserted in the housing main shaft hole 53, the inner side wall of the housing main shaft hole 53 is provided with a positioning groove 54 connected with the housing main shaft hole 53, the positioning protrusion 32 is swingably arranged in the positioning groove 54, and the positioning protrusion 32 is respectively limited by a pair of side walls of the positioning groove 54 to position the main shaft 3 in the first position and the second position. It should be noted that other methods can also be used to limit the main shaft 3 and the housing, such as a groove is provided on the main shaft 3, and a limiting protrusion is provided on the housing. In addition, the main shaft 3 also includes a spring mounting portion 33, and two spring mounting portions 33 are respectively arranged on the radial sides of the main shaft 3. The spring mounting portion 33 is preferably a groove structure formed by two arc-shaped protrusions arranged on the main shaft body 31, which is used to connect with the energy storage spring 4 of the energy storage mechanism.

[0039] like Figure 2 and Figure 5As shown, the rotation limit structure of the connecting rod 2 of this embodiment, the connecting rod 2 is respectively limited with the housing in the third position and the fourth position to limit the rotation stroke of the connecting rod 2. Specifically, the connecting rod 2 includes a connecting rod shaft cylinder 23 and two connecting rod swing arms 25, the connecting rod shaft cylinder 23 has a connecting rod main shaft hole 24 that is rotationally matched with the main shaft body 31, and the two connecting rod swing arms 25 are symmetrically arranged on both sides of the radial direction of the connecting rod shaft cylinder 23. The connecting rod swing arms 25 are limited with a pair of side walls of the housing to position the connecting rod 2 in the third position and the fourth position respectively. The connecting rod driving part 21 is provided on the other two radial sides of the connecting rod shaft cylinder 23. The connecting rod swing arm 25 is arranged in the direction of the first radial direction of the connecting rod, and the connecting rod driving part 21 is arranged in the direction of the second radial direction of the connecting rod, and the first radial direction of the connecting rod is perpendicular to the second radial direction of the connecting rod. In addition, the connecting rod 2 also includes two connecting rod columns 26, which are respectively vertically connected to the corresponding connecting rod swing arms 25 and are located on both radial sides of the main shaft 3. A spring limiting groove 27 is provided on the inner side of the connecting rod column 26 for connecting to the energy storage spring 4 of the energy storage mechanism.

[0040] like Figure 2-3 As shown, the energy storage mechanism of this embodiment includes at least one energy storage spring 4, and the two ends of the energy storage spring 4 are respectively connected to the main shaft 3 and the connecting rod 2 by transmission; the rotation of the main shaft 3 causes the energy storage spring 4 to rotate to the dead point position to store energy, and the energy storage spring 4 releases energy after passing the dead point position to drive the connecting rod 2 to rotate, so as to drive the turntable 1 to rotate. Preferably, the energy storage mechanism includes two energy storage springs 4, and the two energy storage springs 4 are symmetrically arranged on both sides of the radial direction of the main shaft 3, and the two ends of each energy storage spring 4 are respectively connected to the spring limiting groove 27 and the spring mounting portion 33 of the corresponding connecting rod column 26 by transmission. The energy storage spring 4 of this embodiment is preferably a compression spring, and of course it can also be a torsion spring, a leaf spring or other springs.

[0041] like Figure 2-3 As shown, the main shaft 3 and the connecting rod 2 are coaxially arranged for rotation. When the energy storage spring 4 rotates to the point where the extension lines of the two ends of the energy storage spring 4 pass through the axis of the main shaft 3 or the connecting rod 2, it is the dead point position of the energy storage spring 4. Initially, that is, when the rotary disk 1 is located at the closing position or the opening position for driving the moving contact mechanism and the static contact to close or disconnect, the energy storage spring 4 is located on one side of the dead point position, and cooperates with the housing to keep the main shaft 3 and the connecting rod 2 at the corresponding closing position or the opening position.

[0042] by Figure 2For example, assuming that the turntable 1, the main shaft 3 and the connecting rod 2 are in the closing position, the main shaft 3 is in the first position, and the connecting rod 2 is in the third position, the main shaft 3 is rotated counterclockwise, and before reaching the dead point position, the main shaft 3 will drive one end of the energy storage spring 4 to move, and the other end of the energy storage spring 4 remains stationary with the connecting rod 2. The rotation of the main shaft 3 causes the energy storage spring 4 to store energy. In this embodiment, the main shaft 3 rotates 60° and reaches the dead point position. After the main shaft 3 drives the energy storage spring 4 to cross the dead point position, the energy storage spring 4 releases energy and drives the connecting rod 2 to rotate 60° clockwise to the fourth position. At the same time, the turntable 1 will first be driven by the connecting rod 2 to rotate and then continue to rotate to 90° due to inertia. The rotation angle of the turntable 1 is greater than the rotation angle of the connecting rod 2. The main shaft 3 will continue to rotate counterclockwise by another 30° to the second position of 90°. At this time, the turntable 1, the main shaft 3 and the connecting rod 2 remain in the corresponding opening position. Closing operation is a reverse operation, driving the main shaft 3 to rotate clockwise, and the process is similar to the opening process. It should be noted that the rotation angle can be adjusted and set as needed, and it is not limited to that the spindle will inevitably drive the turntable 1 to rotate 90° after reaching the dead point position after rotating 60°.

[0043] like Figure 7-8 As shown, the housing of this embodiment includes an upper base 6, a lower base 5 and a pressure plate. The upper base 6 covers the lower base 5 to form an installation chamber for installing the turntable 1, the connecting rod 2 and the main shaft 3. The turntable hole 51 is formed by splicing a semicircular hole of the upper base 6 and the other semicircular hole of the lower base 5. The rotation groove 52 is formed by splicing a half groove of the upper base 6 and the other half groove of the lower base 5. The upper base 6 is provided with an upper base main shaft hole for the main shaft 3 to pass through. The pressure plate cooperates with the bottom wall of the lower base 5 to limit the axial movement of the connecting rod 2. The main shaft hole 53 of the housing is arranged on the bottom wall of the lower base 5. The positioning groove 54 includes two arc grooves arranged on the bottom wall of the lower base 5 and located on both sides of the radial direction of the main shaft hole 53 of the housing. Correspondingly, as shown in FIG. Figure 6 As shown, the positioning protrusion 32 includes two arc-shaped protrusions arranged on both sides of the main shaft body 31 in the radial direction.
