Document Type and Number:
WIPO Patent Application WO/2024/008170
Kind Code:
A1
Abstract:
A pulling and locking structure of a circuit breaker, comprising a housing of the circuit breaker. A handle mechanism is rotatably assembled at an operation end of the housing, an operation mechanism and a locking mechanism are provided in the housing, and the handle mechanism is in linkage with the operation mechanism to drive the circuit breaker to open and close. The pulling and locking structure further comprises a cover plate rotatably connected to the housing; the cover plate is provided with an operation part and a second driving part; the cover plate rotates between a retracted position and an open position; when the cover plate rotates to the retracted position, the operation part is close to an end surface of the operation end; and when the cover plate rotates to the open position, the second driving part drives the locking mechanism to unlock, and the operation part is distant from the end surface of the operation end for pulling the circuit breaker. According to the present invention, the collapsible cover plate is provided; when the circuit breaker is disassembled, the cover plate is opened, the second driving part of the cover plate unlocks the locking mechanism at the same time, and the operation part after the cover plate is opened can apply a pulling force or work in conjunction with a disassembling tool to pull the circuit breaker, so that the present invention has the advantages of being simple in structure, high in stability, and convenient to pull compared with existing circuit breakers which are pulled by means of button pieces.
