Abstract

A bullet cabinet emergency unlocking device comprises an electric control lock, a latch, a horizontal-moving connecting plate and a four-way linkage latch. One end of the horizontal-moving connecting plate is connected with the four-way linkage latch. The other end of the horizontal-moving connecting plate is connected with the latch. One end of the latch is movably connected with the horizontal-moving connecting plate through a pin shaft or a bolt. A free end of the latch is provided with an electric control lock tongue groove. An electric control lock tongue arranged on a cabinet door is matched with the electric control lock tongue groove. An emergency lock tongue groove is formed in the middle of the latch. An emergency lock tongue arranged on the cabinet door is connected with a bent hook which is inserted into the emergency lock tongue groove. The emergency lock tongue drives the latch to rotate around the pin shaft or the bolt on the horizontal-moving connecting plate through the bent hook. The bullet cabinet emergency unlocking device has the advantages of being novel in structure and high in reliability, when the electric control lock is in failure, an emergency lock works, the emergency lock drives the bent hook and the latch, so that the latch rotates around the pin shaft or the bolt on the horizontal-moving connecting plate, the electric control lock tongue is separated from the electric control lock tongue groove in the latch, latch moves freely, and emergency unlocking is achieved.
