The invention discloses an integrated self
interlocking mechanism with a
brake breaking function. The integrated self
interlocking mechanism comprises a pedestal, a pull rod, a
brake breaking spring,a magnetic shell, a
tripping coil, a lock tongue, a reset spring and a yoke, a longitudinal hole penetrating the pedestal is formed in the pedestal, and the middle part of the pull rod movably penetrates the longitudinal hole; a limit block is fixed on one end, extending out the pedestal, of the pull rod, and the
brake breaking spring sheathes the other end, extending out the pedestal, of the pullrod; the magnetic shell is fixed on one side surface of the pedestal; one end of the
tripping coil is arranged at the bottom of the magnetic shell, the other end of the
tripping coil clings one sidesurface of the yoke, and the other side surface of the yoke is fixed on the pedestal; a lock hole communicated with the longitudinal hole is formed in the yoke and the pedestal corresponding to the center of the tripping coil, one end of the lock tongue is placed at the center of the tripping coil, the other end of the lock tongue is placed in the lock hole, and the reset spring is located betweenthe lock tongue and the bottom of the magnetic shell; and an
interlocking slot is formed in the periphery of the pull rod. The integrated self interlocking mechanism disclosed by the invention integrates three functions, namely a brake closing self interlocking function, a brake breaking driving function and a
stroke adjusting function, into a whole, so that not only parts are reduced but also structure is simple and compact.
