Abstract
The utility model discloses an inner control mechanism for a ring network cabinet. The inner control mechanism comprises a same-rotary-direction electric mechanism and a ring-network cabinet built-in operation mechanism which are connected, wherein the same-rotary-direction electric mechanism enables a transmission output shaft of a gear transmission module and one end of a transmission crank driven by the transmission output shaft to always rotate along a same direction. When the other end of the transmission crank is furthest from or closest to a sensitive switch respectively, the sensitive switch controls a main switch to open and close. The ring-network cabinet built-in operation mechanism comprises a large cam assembly and a small cam assembly. When the large cam assembly is rotated to open the main switch, the large cam assembly links the small cam assembly to drive a grounding switch to open or close. When the large cam assembly is rotated to close the main switch, the large cam assembly links the small cam assembly to restrict the grounding switch to open. The mechanism provided by the utility model can avoid a condition of manual damage of the transmission system or the switch body because the control system and the sensitive switch are in a failure state. Furthermore, a size of the mechanism is reduced and can be mounted in a gas casing, a maintenance-free function is realized and the inner control mechanism can preferably adapt to external harsh environments.
