Abstract
The invention discloses a clamping plate type operating mechanism for a load switch. The clamping plate type operating mechanism comprises an input shaft, a front transmission disc, a rear transmission disc, springs, a guide loop bar, stripper rods, an output disc, fixing columns and a fixing plate. The output shaft rotates under the action of external force to drive the front transmission disc and the rear transmission disc to rotate. The front transmission disc and the rear transmission disc push guide wheels to compress the springs for energy storage through centrosymmetric long circular grooves. When the front transmission disc and the rear transmission disc move to a critical position, stripper rod groove holes in the front transmission disc pull the stripper rods to move to the center of a circle, the stripper rods further pull limiting blocks to move to the centers of the discs, the springs continue to store energy, when the limiting blocks move to the critical position, the limiting blocks are disengaged from the stripper rods, the energy storage springs instantly release energy, the output disc is pushed by the guide wheels and then acts on the load switch, and eventually the switching-closing function of the load switch is achieved. A drive part, an energy storage part and an output part are arranged between two clamping plates, the clamping plate type operating mechanism is simple in operation, novel in structure, reliable in motion and small in size, the number of parts is reduced, and reliability of the mechanism is improved.
