One end of the third slider rod 13 is provided with a sliding groove 131 matched with the sliding part 121, and the sliding part 121 is limited in the sliding groove 131. The other end of the third slider rod 13 is a fixed rotary center and is connected with a switch movable contact transmission shaft 6. The switch movable contact transmission shaft 6 transmits the force of the operating mechanism to the movable contact. The four-bar linkage slider unit 1 and a main tension spring 23 of the energy storage unit 2 move coordinately, can drive the switch movable contact to rotate by not less than 90 degrees, and complete tripping movement.

[0069] The energy storage unit 2 comprises a jump buckle 21, a lock buckle 22 and the main tension spring 23, has a locking function, and locks the four-bar linkage slider unit 1 when the switch device is in the closing state, so that the switch movable contact is kept in the closing state. The two ends of the main tension spring 23 are connected with the second slider rod 12 and the jump buckle 21 respectively, and provide the operating mechanism with the required force when closing and opening. The main tension spring 23 stores energy and pulls the four-bar linkage slider unit 1 to move quickly, so that the switch movable contact transmission shaft 6 rotates to a tripping and opening position, thereby making the switch open. The jump buckle 21 is provided with a rotary positioning shaft 211 and a limiting pin 212, and the jump buckle 21 is locked by the lock buckle 22 in the closing and tripping and opening states. In the tripping state, the first slider rod 11 rotates the jump buckle 21 by acting on the limiting pin 212, until the tripping and opening state is realized. The jump buckle 21 and the lock buckle 22 can complete energy storage in the tripping state.

[0070] The remote tripping unit 3 has a signal receiving function, is used for receiving an opening signal, and can realize the tripping and opening of the jump buckle 21 and the lock buckle 22 by controlling the lock buckle 22.

[0071] The operating mechanism in the embodiment further comprises a handle centering unit 4, which is in transmission connection with the first slider rod 11 and is provided with an operating handle driving groove 44 for mounting an operating handle. The operating handle driving groove 44 can rotate around its center, and is concentrically arranged with the rotary center of the switch movable contact transmission shaft 6. If necessary, the rotary center of the operating handle driving groove 44 can also be installed at other positions.

[0072] The handle centering unit 4 adopts a connecting rod transmission structure or a gear transmission structure or other transmission structures to provide a rotation angle of not less than 90° for the operating handle. The four-link slider unit 1 is used to realize power transmission between the handle centering unit 4 and the moving contact transmission shaft 6 of the switch.

[0073] The operating mechanism in the embodiment further comprises a supporting accessory 43 for providing support for the handle centering unit 4.

[0074] The energy storage unit 2 further comprises a lock catch counter-force spring 24 for keeping the lock catch 22 in a state of locking the trip catch 21.

[0075] The housing 5 of the operating mechanism is provided with limiting members for limiting the lock catch 22, the trip catch 21, the second slider rod 12 and the third slider rod 13 respectively, so as to assist the operating mechanism to realize the functions of closing, tripping and reclosing.

[0078] As shown in Figure 18 , the structure of the handle cap 56 can be designed according to actual needs, which can be a rotary knob. If the stiffness and pre-tightening force of the main tension spring 23 are large, the handle operating force becomes large, and then a handle cap 56 with a long handle can be used to facilitate manual closing, opening and reclosing.

[0079] Embodiment One

[0080] As shown in Figure 1 , Figure 2 , the handle centering unit 4 in the embodiment comprises a first handle transmission rod 41 and a second handle transmission rod 42. One end of the second handle transmission rod 42 is hinged with the first slider rod 11, and the other end is hinged with one end of the first handle transmission rod 41. The other end of the first handle transmission rod 41 serves as a rotation center thereof, and is provided with an operating handle driving groove 44. If the product does not need a handle centering, a new design can be adapted by changing the position of the rotation center of the first handle transmission rod 41.

[0081] AsFigure 3 As shown, the first slider rod 11 is provided with a rotating orientation structure 111, and a cylindrical protrusion is formed on both sides of the first slider rod 11 for rotating positioning with the operating mechanism upper shell 51 and the bottom shell 52. The hollow structure of the first slider rod 11 provides space for the second slider rod 12. The support accessory 43 provides support for the first handle transmission rod 41. The hollow cavity of the support accessory 43 provides movement space for the third slider rod 13, while blocking the lower on-off device 9 to provide air tightness.

[0082] As shown, Figure 4 In this embodiment, the sliding part 121 of the second slider rod 12 is a pin, which is limited in the sliding channel 131 of the third slider rod 13. The second slider rod 12 includes two parts connected in sequence, and has a cavity inside for accommodating the movement of the main tension spring 23. A first main tension spring hanging point 122 is arranged in the middle of the second slider rod 12.

[0083] As shown, Figure 5 The position where the first slider rod 11 limits the second slider rod 12 is a circular arc-shaped positioning groove 112. The end of the second slider rod 12 limited in the circular arc-shaped positioning groove 112 is arc-shaped, and serves as the rotation center of the second slider rod 12.

[0084] As shown, Figure 6 The lock catch 22 is provided with a fixed rotating center. In this embodiment, the lock catch 22 is fixed on the shell 5 for rotation through a lock catch fixing pin 223. A clasp structure 221 capable of fixing the jump catch 21 is arranged on one side of the rotating center of the lock catch 22. The other side is connected with the remote tripping unit 3, and is provided with a tripping structure 222. The tripping structure 222 is connected with the manual tripping button 57, and the connection surface is inclined to the direction in which the manual tripping button 57 is pressed. Various tripping structures 222 can be designed to adapt to various trippers, and the lock catch 22 is rotated counterclockwise to achieve tripping.

[0085] The rotating positioning shaft 211 and the limiting pin 212 of the jump catch 21 are as shown. Figure 7 The jump catch 21 is fixed on the shell 5 for rotation through the rotating positioning shaft 211. The protruding structure at the other end of the jump catch 21 together with the clasp structure 221 of the lock catch 22 completes the re-catch. The middle part of the jump catch 21 is provided with a mounting hole as a second main tension spring hanging point 213 for mounting the main tension spring 23, as shown. Figure 8

[0086] The layout of the remote tripping unit 3 is as shown. Figure 9 The remote tripping unit 3 can receive signals such as electric signals, and make the lock catch 22 deflect through the tripping top rod 31 to achieve the tripping of the jump catch 21 and the lock catch 22, and complete the remote tripping.

[0087] As shown, Figure 12 ​Figure 3 shows the lever state diagram of the four-bar linkage slider unit 1 and the handle centering unit 4 in the closed state. When the switch is closed, the main tension spring 23 provides a pulling force, the second slider lever 12 is subjected to a force rotating clockwise, driving the third slider lever 13 and the moving contact of the on-off device 9 to rotate clockwise, and being limited in movement by the first limiting member 53 on the shell 5, so that the switch moving contact is locked in the closed position. The lock catch counterforce spring 24, together with the fourth limiting member 59 of the bottom shell 52, keeps the lock catch 22 in the state of hanging on the trip catch 21. At this time, the connecting rod of the handle centering unit 4 is kept in the closed indication position.

[0088] As shown in Figure 4, the lever state diagram of the four-bar linkage slider unit 1 and the handle centering unit 4 in the tripped open state is shown. After the trip catch 21 is tripped, under the action of the pulling force of the main tension spring 23, the second main tension spring hanging point 213 on the trip catch 21 moves from the left side of the second slider lever 12 to the right side, and the trip catch 21 contacts the second limiting member 54 of the shell 5. This makes the second slider lever 12 subjected to a force rotating counterclockwise, and drives the third slider lever 13 to rotate until it contacts the third limiting member 55, completing the tripped open. At this time, the connecting rod of the handle centering unit 4 rotates counterclockwise to the tripped open indication position. Figure 13 As shown in Figure 5, the lever state diagram of the four-bar linkage slider unit 1 and the handle centering unit 4 in the reclosing state is shown. In the tripped state, the handle is operated counterclockwise, and the connecting rod of the handle centering unit 4 drives the first slider lever 11 to rotate clockwise. Under the combined action of the pulling force of the main tension spring 23 and the third limiting member 55, the second slider lever 12 is pulled towards the first slider lever 11, and slides with the third slider lever 13. At this time, the first slider lever 11 contacts the limiting pin 212 on the trip catch 21, forcing the trip catch 21 to rotate counterclockwise until it is reclosed. At this time, the handle is released and remains in the reclosed open position.

[0089] Figure 14 Example Two

[0090] When the operating mechanism is connected to the multi-layer on-off device 9, a greater pulling force of the main tension spring 23 may be needed to drive the operating mechanism.

The fixed pin is protruded on both sides of the jump buckle 21, and two main tension springs 23 can be installed to provide tension. Correspondingly, the second slider rod 12 and other components are also widened to adapt to the width of the two main tension springs 23. The first main tension spring hanging point 122 of the second slider rod 12 adopts the form of a main tension spring fixing shaft 123, and the diameter of the fixing shaft is increased to bear greater tension, as shown in Figure 27 .
