Abstract

Embodiments of the disclosure provides a reset module for a handle mechanism, a handle mechanism and a switching device. The reset module comprises: a rotary table fixedly coupled to a rotary handle of the handle mechanism and adapted to rotate with the rotary handle about a rotary axis at least between a closed position and an open position; a first driving block arranged at a circumferential edge of the rotary table and adapted to contact a joystick of a circuit breaker during rotation of the rotary table from the closed position to the open position; and an elastic member coupled to the rotary table and adapted to provide an elastic force between the first driving block and the joystick such that the rotary table is held in the closed position. In this way, the rotary handle can accurately indicate the current state of the switching device.

Dependent claims

A reset module for a handle mechanism, comprising:

a housing;
a rotary handle rotatably coupled to an outside of the housing;
a rotating table fixedly coupled to the rotary handle and adapted to rotate with the rotary handle about a rotary axis at least between a closed position and an open position;
a first driving block arranged at a circumferential edge of the rotating table and adapted to contact a joystick of a circuit breaker during rotation of the rotating table from the closed position to the open position and to push the joystick from an on position to an off position for controlling on and off of the circuit breaker;
and
an elastic member coupled to the rotating table and adapted to provide an elastic force between the first driving block and the joystick during the rotating table being in the closed position such that the rotating table is held in the closed position, wherein the elastic member comprises:
a coupling portion fixedly coupled to the rotating table;
and
a deforming portion coupled to the coupling portion and arranged to press against the joystick at least during the rotating table being in the closed position.
