Reset module for handle mechanism, handle mechanism and switching device
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.

4 . The handle mechanism of claim 3 , further comprising:
a second driving block arranged at the circumferential edge of the rotating table and spaced circumferentially by a predetermined angle from the first driving block, the second driving block adapted to contact the joystick during rotation of the rotating table from the open position to the closed position and to push the joystick from the off position to the on position.
5 . The handle mechanism of claim 4 , wherein the fastener passes simultaneously through the rotating table and the rotary handle, and is respectively coupled to the rotating table and the rotary handle to fix the rotating table on the rotary handle.
6 . The handle mechanism of claim 1 , further comprising:
a microswitch coupled to the housing and adapted to be triggered by the first driving block during the rotating table being in the closed position.
7 . The handle mechanism of claim 1 , further comprising:
a locking member movably coupled to the rotary handle, the locking member adapted to be driven and at least partially inserted into at least one location hole to secure the rotary handle to a shell.
8 . The handle mechanism of claim 7 , further comprising:
a driving assembly adapted to control insertion of the locking member into the at least one location hole and comprising:
a rotary knob coupled to the rotary handle; and
a driving member coupled between the rotary knob and the locking member, and adapted to drive the locking member to be inserted into the at least one location hole with rotation of the rotary knob.
9 . A switching device comprising:
a circuit breaker comprising a joystick for controlling on and off of the circuit breaker; and
a handle mechanism, the 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 the joystick 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; 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.
10 . The switching device of claim 9 , wherein the rotating table further comprises a fixing groove passing through a center of the rotating table and extending radially toward the first driving block, the fixing groove adapted to receive the coupling portion.
11 . The switching device of claim 10 , wherein the handle mechanism further comprises:
a fastener coupled to the coupling portion and configured to couple the coupling portion into the fixing groove.
12 . The switching device of claim 11 , wherein the handle mechanism further comprises:
a second driving block arranged at the circumferential edge of the rotating table and spaced circumferentially by a predetermined angle from the first driving block, the second driving block adapted to contact the joystick during rotation of the rotating table from the open position to the closed position and to push the joystick from the off position to the on position.
