Abstract
The interlocking mechanism includes micro switch for usual power supply (MSUPS) and micro switch for stand-by power supply (MSSPS), as well as mounting plate, motor drive mechanism, cam and two connecting rods. The motor drive mechanism is installed at low part of the mounting plate. MSUPS and MSSPS, cam and two connecting rods are installed at up part. MSUPS and MSSPS are setup at two ends of the mounting plate. The cam is installed at middle of the mounting plate. Being setup between the cam and the two micro switches, the two connecting rods connected and contacted to two micro switches are in use for controlling on / off for them. Preventing disadvantages of poor reliability, and miscellaneous structure of four bar linkage mechanism, the disclosed interlocking mechanism uses lever structure, and rolling bearing to make interlocking mechanism compact, and reasonable so as to raise reliability of action.
