Two mounting posts disposed in parallel of U-shaped bar.
As shown in Figures 2 to 4, the working principle of small type circuit breaker operating mechanism of the invention is as follows:
It closes a floodgate:
When original state, operating mechanism is in open position shown in Fig. 3, pushes push button 4 to overcome the first bias piece manually
41 active force moves right, and push button 4 drives moving contact 2 to rotate clockwise around the first mounting post 11, when push button 4 is moved to Fig. 2
Shown in closing position when, moving contact 2 contacts connection with static contact 3, realizes and closes a floodgate, at this point, the lock tooth 52 and push button of snap close piece 5
4 card slot 42 cooperates locking.
Separating brake:
1) separating brake is realized by push button:
Push button 4 is pushed to be moved to the left manually, since lock tooth 52 and the mutually matched contact surface 54 of the card slot 42 are inclination
Face, when push button 4 is moved to the left, driving snap close piece 5 is rotated counterclockwise, and moving contact 2 is driven to turn counterclockwise around the first mounting post 11
It is dynamic, separate moving contact 2 with static contact 3, to realize separating brake.
2) separating brake is realized by button:
Manual actuation button 6 moves down, and button 6 offsets with the first cursor 51, and driving snap close piece 5 rotates counterclockwise,
The lock tooth 52 of snap close piece 5 and the card slot 42 of push button 4 unlock, and push button 4 is moved to the left under the action of the first bias piece 41, and is driven
Moving contact 2 is rotated counterclockwise around the first mounting post 11, separates moving contact 2 with static contact 3, to realize separating brake.
Obviously, the above embodiments are merely examples for clarifying the description, and does not limit the embodiments.It is right
For those of ordinary skill in the art, can also make on the basis of the above description it is other it is various forms of variation or
It changes.There is no necessity and possibility to exhaust all the enbodiments.And it is extended from this it is obvious variation or
It changes still within the protection scope of the invention.
