[0025] Example 1:

[0026] See also Figures 1-4 The utility model provides a technical solution: an operating mechanism for an isolating switch, comprising a mechanism component; the mechanism component is mounted inside a base 9, and a cover is mounted on the top of the base 9 by screws;

[0027] The mechanism components include an isolating switch operating handle 1, one end of the isolating switch operating handle 1 passes through the bottom of the base 9, and the other end is fixedly connected to one end of the active rotating shaft 7 through the bracket 8, the other end of the active rotating shaft 7 is fixedly connected to one end of the two transmission shafts 5, and the other ends of the two transmission shafts 5 are installed with a passive rotating shaft 6, a spring bracket 4 is installed on the outside of the transmission shaft 5, a spring 3 is installed on the outside of the spring bracket 4, a spring baffle 2 is installed on the outside of the spring 3, and the spring baffle 2 is stuck in the card slot inside the base 9.

[0028] The spring bracket 4 comprises a U-shaped plate 41, with the drive shaft 5 extending through its two side panels. A stopper rod 42 is integrally formed within the U-shaped plate 41 and inserted into the interior of the spring 3. A waist-shaped rod 31 is integrally formed at the outer end of the spring 3, and the outer end of the waist-shaped rod 31 extends through the spring stop plate 2. The center of the spring stop plate 2 is formed by a curved plate 21, through which the waist-shaped rod 31 extends. A locating pin is installed on the outer side of the curved plate 21 and within the waist-shaped rod 31, thus limiting the installation of the spring 3.

[0029] Attachment Figure 1 、 2This is a schematic diagram of the mechanism in an embodiment of the present invention. The mechanism components are fixed to the cover; in the center of the base 9. When the disconnector operating handle 1 is operated, the connecting shaft drives the active shaft 7 to move. The active shaft 7 also drives the passive shaft 6 and the spring bracket 4 to move. The spring bracket 4 stores energy in the spring. When the spring passes the inflection point, the potential energy is released. The spring bracket 4 drives the active shaft 7, which in turn drives the passive shaft 6. The passive shaft 6 then drives the movable contact of the disconnector, achieving the disconnector's closing and opening operations.

[0030] Attachment Figure 3 This is the schematic diagram of the mechanism's operation. When the disconnector handle 1 is manually operated and rotated counterclockwise from the open position shown, it drives the active shaft 7 from the 45° position shown. The spring support 4 rotates 61°. At this point, the spring reaches its inflection point and begins to release potential energy. This energy causes the spring support 4 to continue moving counterclockwise, with the speed of movement controlled by the spring potential energy. The spring support 4 then drives the active shaft 7 and the passive shaft 6 counterclockwise, separating the connecting shaft of the disconnector handle 1 from the active shaft 7. The passive shaft 6 then drives the disconnector's moving contact to close. When the spring support 4 drives the active shaft 7 and the passive shaft 6 to the predetermined position, the active shaft 7 and the passive shaft 6 contact the second contact point of the disconnector handle 1, driving the disconnector handle 1. When these components continue to move to the position where the disconnector's moving contact has closed, the disconnector's moving contact is restrained and no longer moves, transmitting power to the passive shaft 6. The active shaft 7 remains in the closed position. At this time, the counterclockwise movement direction of the isolating switch operating handle 1 is restricted by the limit block of the base 9 and stays at Figure 4 The closing position is 45°; the clockwise movement is pushed by the second contact point of the active shaft 7 and stays in the closing position. At this time, the angle between the center point of the connecting shaft of the disconnector operating handle 1 and the vertical direction is -45°. The angle between the transmission center point of the spring bracket 4, the active shaft 7, and the driven shaft 6 connected together by the transmission shaft 5 and the vertical direction is 29°. Figure 4 shown.

[0031] As attached Figure 4As shown, when the manually operated disconnector handle 1 is rotated clockwise from the closed position shown, it drives the active shaft 7 from the -45° position shown. The spring support 4 rotates 61°. At this point, the spring reaches its inflection point and begins to release potential energy. This energy causes the spring support 4 to continue moving clockwise, with the speed of movement controlled by the spring potential energy. At this point, the spring support 4 drives the active shaft 7. The passive shaft 6 continues to move clockwise, separating the connecting shaft of the disconnector handle 1 from the active shaft 7. The passive shaft 6 then drives the disconnector's moving contact to open. When the spring support 4 drives the active shaft 7 and the passive shaft 6 to the predetermined position, the active shaft 7 and the passive shaft 6 contact the first contact point of the disconnector handle 1, and both drive the disconnector handle 1 to move. When these components continue to move to the position where the disconnector's moving contact has completed opening, the disconnector's moving contact is restrained and no longer moves, transmitting the power to the passive shaft 6. The active shaft 7 remains in the open position. At this time, the clockwise movement direction of the isolating switch operating handle 1 is restricted by the limit block of the base 9 and stays at Figure 3 The opening position is 45°; the counterclockwise movement is pushed by the first contact point of the active shaft 7 and stays in the opening position. At this time, the angle between the center point of the connecting shaft of the disconnector operating handle 1 and the vertical direction is 45°. The angle between the transmission center point of the spring bracket 4, the active shaft 7, and the driven shaft 6 connected together by the transmission shaft 5 and the vertical direction is 29°. Figure 3 shown.

[0032] When the closing and opening stroke of the disconnector changes, the closing and opening angles of the mechanism are changed to adapt to the closing and opening stroke of the disconnector.

[0033] Embodiment 2: Provide a new operating mechanism for an isolating switch, such as Figure 5 and Figure 6 As shown:

[0034] The mechanism components are fixed between the base and the cover and include a left spring sleeve 1, a left spring 2, a left spring bracket 3, a passive shaft 4, an operating handle 5, a right spring 6, a right spring bracket 7, a right spring sleeve 8, and a driving shaft 9. When the handle 5 is manually operated, the driving shaft 9 is driven to move through the contact point. The driving shaft 9 then drives the passive shaft 4 through the bevel gear. Connected by a pin, the driving shaft 9 drives the left spring bracket 3 and the right spring bracket 7, which in turn moves the left spring 2 and the right spring 6. When the spring passes the inflection point, the potential energy is released and, through the left spring bracket 3 and the right spring bracket 7, the driving shaft 9 continues to move in the same direction. The driving shaft 9 drives the passive shaft 4, which in turn drives the movable contact of the disconnector, achieving the closing and opening operations of the disconnector.

[0035] The utility model places the closing and opening operating mechanism constituting the main space of the mechanism in a parallel position with the moving and static contacts of the isolating switch. When operating the isolating switch to close or open, the operating handle can be placed on the left or right side of the isolating switch to operate the isolating switch to close or open.

[0036] The utility model divides the stroke of the operating handle into two parts. The first stroke realizes the energy storage of the spring. The second stroke is when the spring passes the inflection point and releases the potential energy to drive the disconnector to close and open. The active rotating shaft and the passive rotating shaft can move freely, thereby realizing the rapid closing and opening of the disconnector.

[0037] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
