Title:
AUTOMATIC OPENING MECHANISM
Document Type and Number:
WIPO Patent Application WO/2024/051722
Kind Code:
A1
Abstract:
The present invention relates to the field of low-voltage electrical apparatuses, and in particular to an automatic opening mechanism, comprising an operating shaft, a delayed energy-storage mechanism, a reset mechanism and a tripping mechanism. The delayed energy-storage mechanism comprises a rotating disk and a first energy-storage spring, the reset mechanism comprises a reset gear, and the tripping mechanism comprises a tripper. The tripper triggers the delayed energy-storage mechanism in an energy-storage state; and the first energy-storage spring releases energy to drive the rotating disk to rotate from an energy-storage position to an energy-release position so that the delayed energy-storage mechanism switches to an energy-release state, and at the same time, the operating shaft is driven to rotate from a closing position to an opening position. The operating shaft rotates from the opening position to the closing position, and the rotating disk is driven to rotate from the energy-release position to the energy-storage position, thereby driving the first energy-storage spring to store energy, so that the delayed energy-storage mechanism switches from the energy-release state to the energy-storage state; and at the same time, the rotating disk meshes with the reset gear to drive same to rotate, and the reset gear drives the tripper to reset. Therefore, the automatic opening mechanism realizes remote opening operations and the automatic resetting of the tripping mechanism.
