Title:

UNIVERSAL CIRCUIT BREAKER ENERGY STORAGE HANDLE ANTI-JAMMING APPARATUS

Document Type and Number:

WIPO Patent Application WO/2018/072255

Kind Code:

A1

Abstract:

A universal circuit breaker energy storage handle anti-jamming apparatus, comprising a circuit breaker body, an operating mechanism mounted at a side of the circuit breaker body, and an energy storage handle mounted on the outer sidewall of a side of the operating mechanism. The energy storage handle is rotated to manually store energy in the operating mechanism. The operating mechanism comprises a V-shaped rotating shaft. One extremity of the V-shaped rotating shaft protrudes the sidewall at a side of the operating mechanism. One extremity of the V-shaped rotating shaft is sleeved with a ratchet linked to the energy storage handle. A cleat linked to the ratchet is provided on the side of the energy storage handle facing the ratchet. The rotation of the energy storage handle drives via the cleat the ratchet to rotate. An anti-jamming structure preventing the cleat and the ratchet from jamming is provided between the cleat and the ratchet. The anti-jamming structure comprises an anti-jamming plate. When the energy storage handle is in an initial state, the anti-jamming plate separates the cleat from the ratchet.
