The course of work of present embodiment: referring to accompanying drawing 1, apply active force on handle 9, rotate counterclockwise cam 10, left lever 6 is subjected to cam 10 active forces to draw left cantilever 5 drive left-handed opening rotating shafts 21 and rotates counterclockwise the operational motion that realization power supply I connects at this moment.In this process, left cantilever 5 drives left push rod 2 and does under the constraint of left guide finger 3 to the motion of cam 10 directions, for power supply I disconnection is next time prepared; In this process, right pull bar 12 is dodged action by elongated slot 19, in order to avoid interfere cam 10 to rotate, thereby keeps right switch rotating shaft 22 motionless; Parts relative position after accompanying drawing 2 moves for this reason.
Under state shown in the accompanying drawing 2, on handle 9, apply active force, clockwise rotate cam 10, the profile of cam 10 produces roller 7 and conflicts, left side push rod 2 is subjected to active force to drive left cantilever 5 rotations, drive left-handed opening rotating shaft 21 and clockwise rotate, thereby realize that power supply I disconnects, and gets back to the operating state that power supply I shown in the accompanying drawing 1 and power supply II disconnect simultaneously.In this process, cam 10 drives left levers 6,12 motions of right pull bar, dodges action by the elongated slot 19 of left lever 6, right pull bar 12, so right cantilever 14 can not rotate, and is that the connection of power supply I or power supply II is next time prepared.
Disconnect simultaneously under the operating state at power supply I shown in the accompanying drawing 1 and power supply II, apply active force on the handle 9, clockwise rotate cam 10, right pull bar 12 is subjected to active force to draw right switch rotating shaft 22 hour hands of right cantilever 14 drives and rotates the operational motion that realization power supply II connects at this moment.In this process, the right push rod 15 of right cantilever 14 drives is done the motion to cam 10 directions under the constraint of right guide finger 16, for power supply II disconnection is next time prepared; In this process, left lever 6 is dodged action by elongated slot 19, in order to avoid interfere cam 10 to rotate, thus keep left-handed opening rotating shaft 21 motionless; Parts relative position after accompanying drawing 3 moves for this reason.
Under state shown in the accompanying drawing 3, on handle 9, apply active force, rotate counterclockwise cam 10, the profile of cam 10 produces roller 13 and conflicts, right push rod 15 is subjected to active force to drive right cantilever 14 rotations, drive right switch rotating shaft 22 and rotate counterclockwise, thereby realize that power supply II disconnects, and gets back to the operating state that power supply I shown in the accompanying drawing 1 and power supply II disconnect simultaneously.In this process, cam 10 drives left levers 6,12 motions of right pull bar, dodges action by the elongated slot 19 of left lever 6, right pull bar 12, so left cantilever 5 can not rotate, and is that the ON Action of power supply I or power supply II is next time prepared.
This mechanism is that linkage and cam mechanism organically combine the combined mechanism that forms.In the transfer process of above-mentioned three kinds of states, the feed motion of switch is realized that by linkage the separating brake action of switch is realized by cam mechanism; This operating mechanism has three stop positions, thereby has accurately indicated the operating state of automatic transfer switching electric appliance; Under three states, because the combination of linkage and cam mechanism, left side push rod 2 can only move separately in order with right push rod 15, otherwise left push rod 2 can form with cam 10 with right push rod 15 and interfere, thereby has avoided the appearance of the phenomenon of the failure that power supply I and power supply II connect simultaneously effectively.
