Abstract

The invention provides a combined electric appliance three-position mechanism comprising a frame; the frame is provided with a grounding switch operating device, a closing switch operating device, a three-position output device and a trip gear; the three-position output device comprises an output shaft sleeve and a first connecting lever connected in a rigid manner; the output shaft sleeve and theframe rotatably match; a differential plate is arranged on one side of the first connecting lever, and provided with a first slide groove; a first drive pin is arranged on the other side of the firstconnecting lever, and rotatably connected with a first connecting rod; when a spring energy storage device rotates to the maximum energy storage position, the storage energy is released so as to enable a main switch operating device to continuously rotate; the main switch operating device drives the three-position output device to rotate via the first connecting rod and the first drive pin, thusoutputting a torque. The mechanism can realize closing-opening-grounding three-position switching operations via two input positions and one output position, is compact in structure, and easy to use.

Description

technical field [0001] The invention relates to a three-station mechanism, in particular to a three-station operating mechanism for combined electric appliances. Background technique [0002] The mission of the load switch is to realize the connection and disconnection of the circuit through the opening and closing action of the contact, and the opening and closing action of the contact is realized by the operating mechanism. The existing operating mechanism is complex in structure, difficult to manufacture and cumbersome to operate. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a three-station mechanism of combined electrical appliances, which can realize the three-station switching operation of closing-opening-grounding through two input stations and one output station. convenient. [0004] The technical scheme that the present invention solves technical problem adopts is: [0005] A three-station mechanis...
