When closing the switch, the opening reset member 24 is stretched by an external force, so as to have an elastic force to drive the touch control member 23 to reset the opening switch.

[0033] refer to Figures 1 to 8The cam 322 is provided with a protruding portion 324 which is provided on the cam surface of the fixing portion 34. The cam 322 is provided with a protruding portion 324 which is provided on the cam surface of the fixing portion 34. The cam 322 is provided with a protruding portion 324 which is provided on the cam surface of the fixing portion 34. The cam 322 is provided with a protruding portion 324 which is provided on the cam surface of the fixing portion 34. The cam 322 is provided with a protruding portion 324 which is provided on the cam surface of the fixing portion 34.

[0034] The latch pin 313 is connected to the card frame 311, the direct-acting push member 221 is inserted into the card frame 311 and is between the latch pin 313 and the pressing member 312, a pin slot 25 for the latch pin 313 to be clamped is provided at one end of the direct-acting push member 221 away from the driving source 21, a pressing protrusion 26 is provided on the side of the direct-acting push member 221 away from the pin slot 25, the pressing member 312 includes a flat guide portion 3121 and a tilted tongue portion 3122 connected to the flat guide portion 3121; the flat guide portion 3121 is connected to the card frame 311, the tilted tongue portion 3122 is bent toward one side of the direct-acting push member 221, the pin slot 25 includes a guide portion 251 and a clamping portion 252, and the guide portion 251 is arc-shaped;

[0035] When the driving source 21 drives the direct-acting push member 221 to move to close the switch, the direct-acting push member 221 needs to move the guide member. When the direct-acting push member 221 moves along the flat guide portion 3121 on the pressing member 312, no pressure is applied to the pressing member 312. When the pressing protrusion 26 moves to contact the tilted tongue portion 3122 on the pressing member 312, the pressing protrusion 26 applies pressure to the tilted tongue portion 3122. At this time, the buckling elastic member 32 gradually accumulates force and makes the clamping frame 311 have a tendency to rotate around the axis of the connecting member 33. When the position of the pin groove 25 opened in the direct-acting push member 221 moves to correspond to the position of the bayonet 313, the bayonet 313 is clamped into the pin groove 25, thereby making it difficult for the direct-acting push member 221 to continue to move along the guide member.

[0036] refer to Figures 1 to 8The tripping control member 5 includes a tripping power source 51 and a tripping pulling member 52 connected to the tripping power source 51, the tripping power source 51 is connected to the frame 1, the tripping power source 51 is an electromagnet capable of providing a tripping electromagnetic force to the anti-tripping fastener 41, the tripping pulling member 52 includes a moving part 521 and a pulling part 522, the moving part 521 is connected to one end of the pulling part 522, the moving part 521 is connected to the tripping power source 51, the pulling part 522 has a diameter greater than the moving part 521, the anti-tripping mechanism 4 includes an anti-tripping fastener 41 and a reset elastic member 42, the anti-tripping fastener 41 includes a buckle body 411, an ear buckle 412 and a rotating seat 413, the ear buckle 412 is connected to one end of the buckle body 411 Then, rotating seats 413 are arranged on both sides of the buckle body 411, and a through hole 414 for the direct-acting push member 221 to pass through is opened in the buckle body 411, so that the direct-acting push member 221 can pass through the through hole 414 and enter the buckle mechanism 3, and a positioning member 43 connected to the frame body 1 is passed through the rotating seat 413, and the rotating seat 413 can rotate along the axis of the positioning member 43, and a card slot 44 for the release pull member 52 to pass through is opened at one end of the buckle body 411 away from the ear buckle 412, and the card slot 44 is adapted to the outer diameter of the moving part 521, and the reset elastic member 42 is sleeved outside the moving part 521, and one end of the reset elastic member 42 is connected to the release power source 51, and the other end is connected to the buckle body 411;

[0037] Initially, the anti-dropping fastener 41 and the direct-acting push member 221 are in an inclined setting state, and the anti-dropping fastener 41 is not buckled with the buckle component 31; when the buckle component 31 limits the direct-acting push member 221, the clamping frame 311 rotates around the axis of the fixing member 34 until the clamping pin 313 is clamped with the pin groove 25, the clamping frame 311 acts on the rotating seat 413 and drives the rotating seat 413 to rotate around the axis of the positioning member 43, so that the anti-dropping fastener 41 rotates to the position where the direct-acting push member 221 is vertically set, the ear buckle 412 is buckled with the clamping frame 311, and the reset elastic member 42 is in a stretched state, so that the clamping frame 311 is not easy to reset and rotate along the connecting member 33, so that the clamping pin 313 is firmly clamped in the pin groove 25, and the overall stable closing action is maintained;

[0038] When it is necessary to open the switch, the tripping electromagnetic force provided by the tripping power source 51 drives the moving part 521 to move, drives the pulling part 522 to act on the buckle body 411, and drives the buckle body 411 to reset, so that the ear buckle 412 is released from the buckle with the card frame 311, and at the same time, the card frame 311 is reset under the elastic force of the buckling elastic member 32, so that the locking pin 313 is disengaged from the pin groove 25, and the limit on the direct-acting push member 221 is released. Since the switch-opening reset member 24 is in a stretched state when the switch is closed, when the direct-acting push member 221 is released from the limit, the switch-opening reset member 24 releases the elastic force to pull the touch control member 23 to open the switch, thereby realizing stable opening and closing operations.

[0039] Working principle and effect: In the initial state: the opening reset member 24 remains in its original state, the driving source 21 does not provide a closing driving force, the direct-acting push member 221 is inserted into the buckle component 31, the touch control component 23 is in the opening position, the buckle elastic member 32 is in the original length state, the ear buckle 412 on the buckle body 411 is not buckled with the card frame 311, the reset elastic member 42 is in the original length state, and the release pull member 52 does not provide a release pulling force;

[0040] When it is necessary to close the switch, the driving source 21 provides the direct-acting push member 221 to move along the guide plate 12, and drives the touch control unit 23 to perform the closing movement under the action of the transmission crank 222. When the direct-acting push member 221 moves, the pressing protrusion 26 on the direct-acting push member 221 acts on the tilting tongue portion 3122 on the pressing member 312, thereby pressing the tilting tongue portion 3122 downward to drive the buckling elastic member 32 to gradually accumulate force, and under the action of the buckling elastic member 32, the card frame 311 has a downward pressing tendency; when the pin groove 25 on the direct-acting push member 221 moves to a position corresponding to the bayonet 313 on the card frame 311, the card frame 311 drives the bayonet 313 to be pressed down into the pin groove 25, thereby limiting the direct-acting push member 221, and at this time the touch control unit 23 completes the closing movement. When the locking pin 313 is pressed down into the pin groove 25 by the locking frame 311, the locking frame 311 acts on the rotating seat 413 connected to the buckle body 411, providing a downward force to drive the buckle body 411 to rotate along the axis of the positioning member 43, so that when the locking pin 313 is locked with the pin groove 25, the ear buckle 412 is buckled with the locking frame 311, and the buckle mechanism 3 and the direct-acting pusher 221 are prevented from falling off and limited under the action of the anti-falling buckle 41, so that the touch control part 23 can maintain a stable closed state. At this time, the opening reset part 24 is in a stressed and stretched state, and has a tendency to drive the touch control part 23 to reset, and the overall response is fast and the overall structure is stable, so that the closed state can be stably maintained, and the safety of the overall switch when in use is improved;

[0041] When it is necessary to open the switch, the electromagnetic force provided by the tripping power source 51 drives the tripping pulling member 52 to move, and under the action of the tripping pulling member 52, the buckle body 411 is pulled to reset and rotate along the axis of the positioning member 43, so that the ear buckle 412 is disengaged from the card frame 311, and the ear buckle 412 releases the limiting buckle connection to the card frame 311. The card frame 311 is reset under the action of the buckling elastic member 32, driving the locking pin 313 to disengage from the pin groove 25, thereby releasing the limiting of the direct-acting push member 221, and at the same time, the switch opening reset member 24 releases the elastic force to drive the touch control member 23 to reset, and under the action of the transmission crank 222, drives the direct-acting push member 221 to reset and move, thereby realizing a fast and efficient response to the switch opening; the whole can respond quickly when closing or opening the switch, and can maintain a stable closing or opening state, so that the safety of the overall switch is improved.

[0042] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
