Document Type and Number:
WIPO Patent Application WO/2020/114447
Kind Code:
A1
Abstract:
The present utility model discloses a mechanical interlocking mechanism, which is used to interlock a molded case circuit breaker and a drawer, and comprises: a molded case circuit breaker driving rod, which can turn around an axis parallel to and spaced from a longitudinal axis thereof; a blocking assembly; and a locking device, which comprises a driving member, an elastic member and a locking member, wherein the driving member is biased by the elastic member to a locking position at which the locking member locks the drawer into a drawer cabinet, and when the driving member is driven by a biasing force against the elastic member to an unlocking position, the locking member is driven to unlock the drawer. When the molded case circuit breaker is closed, the molded case circuit breaker driving rod drives the blocking assembly to move to a blocking position, the movement of the driving member from the locking position to the unlocking position is blocked, so that the drawer cannot be unlocked; when the molded case circuit breaker is opened, the movement of the molded case circuit breaker driving rod enables the blocking assembly to move to a non-blocking position, and the driving member can be driven from the locking position to the unlocking position, so that the drawer is unlocked.
