Title:
COMBINED ELECTRIC APPLIANCE THREE-POSITION MECHANISM
Document Type and Number:
WIPO Patent Application WO/2019/165813
Kind Code:
A1
Abstract:
Provided is a combined electric appliance three-position mechanism, comprising a frame, wherein the frame is provided with a grounding switch operating device, a closing switch operating device, a three-position output device and a trip device; the three-position output device comprises an output shaft sleeve and a first connecting lever connected in a rigid manner; the output shaft sleeve rotatably matches the frame; a differential plate is arranged on one side of the first connecting lever, and the differential plate is provided with a first slide groove; a first drive pin is arranged on the other side of the first connecting lever, and the first drive pin is rotatably connected to a first connecting rod; when a spring energy storage device rotates over the maximum energy storage position, the storage energy is released so as to enable a main switch operating device to continuously rotate; and at the same time, the main switch operating device drives the three-position output device to rotate via the first connecting rod and the first drive pin, thus outputting torque. The present invention can realize closing-opening-grounding three-position switching operations via two input positions and one output position, and the mechanism has a compact structure and is easy to use.
