Position locking and shifting control mechanism

A position lock and position shift controlling mechanism to control position locking and position shifting of a multi-position shifting switch, said multi-position shifting switch connects with a plurality of equipment and is provided with at least an automation control mode position to control operation of said plurality of equipment by a computer, a stop control mode position, adjacent to said automation control mode position in a preset interval, to stop operation of said plurality of equipment, and a switching shaft to perform a position shift within said automation control mode position and said stop control mode position, the position lock and position shift controlling mechanism comprising:

• a position lock and position shift assembly configured to lock said automation control mode position and to shift said multi-position shifting switch from said automation control mode position to said stop control mode position at a lock status;
• a controlling assembly configured to perform a lock control with respect to said position lock and position shift assembly;
• wherein said position lock and position shift assembly comprises a locked body disposed on said switching shaft, and a moving body controlled by said controlling assembly to move towards and to lock said locked body;
• wherein said locked body comprises:
• a roundel pedestal, disposed on a switch body, rotating synchronously with said switching shaft;
• a notch based on said preset interval;
• a lock tooth component, which is roundel-shaped and is rotatably attached to said roundel pedestal;
• and an inner core component, disposed between said roundel pedestal and said lock tooth component, configured to synchronously rotate said roundel pedestal and said lock tooth component;
• wherein said roundel pedestal comprises an axial slot extending parallel along an axial direction of said switching shaft, said axial slot comprising a through-hole extending along a radial direction of the roundel pedestal;
• wherein said lock tooth component comprises a plurality of location teeth evenly distributed with preset intervals;
• and a plurality of radial slots, each radial slot corresponding to a different location tooth;
• wherein said inner core component comprises an axial projection configured to fit said axial slot;
• a radial projection configured to fit with a radial slot;
• and a forcing member configured to apply a force on said radial projection to insert said radial projection into said radial slot;
• wherein said moving body comprises a lock groove configured to fit a location tooth;
• and a pushing lever configured to push said radial projection to move along said through-hole;
• wherein said controlling assembly comprises a control cam configured to rotatably push said moving body towards said locked body;
• wherein said roundel pedestal and said lock tooth component synchronously rotate in response to said radial projection being fitted into said radial slot;
• wherein in response to said automation control mode position being set so that said notch aligns with said moving body and said moving body moves towards said locked body, said lock groove and said location tooth fit and lock each other, and said pushing lever pushes said axial projection to separate said radial projection from said radial slot, thereby allowing said roundel pedestal to rotate freely about said lock tooth component;
• and
• wherein in response to a rotation of said switching shaft, said notch restricts rotation of said roundel pedestal to one preset interval about said lock tooth component so that said axial projection fits into said axial slot, thereby shifting said multi-position shifting switch into said stop control mode position.
