Abstract

A lock cylinder with functions of unlocking and doubly locking a safety latch by the aid of an original key comprises a lock (1), an outer-side lock cylinder (2), a safety lock control hole (8), a double locking safety bolt (10) and an inner-side lock cylinder (14). The lock (1) is provided with the outer-side lock cylinder (2) and the inner-side lock cylinder (14), a safety lock (7) is sleeved in the inner section of the outer-side lock cylinder (2) of the lock (1), the safety lock control hole (8) is drilled on the safety lock (7) and the lock (1), a pin a, a pin b, a pin c, a pin d and a double locking control spring (9) are arranged in the safety lock control hole (8), then the safety lock control hole (8) is sealed, lower pins (4), upper pins (5) and springs (6) are respectively arranged on a plurality of pin holes which are perpendicular to the outer-side lock cylinder (2) and the lock (1), then the pin holes are sealed, a plurality of pins and springs are arranged in the inner-side lock cylinder (14) and the lock (1), the pins of the inner-side lock cylinder (14) and the lock (1) are encoded in patterns identical to patterns for encoding the outer-side pins of the outer-side lock cylinder (2) and the lock (1), and then the inner-side lock cylinder (14) and the lock (1) are sealed. The lock cylinder has the advantages that owing to the function of doubly locking a safety lock of an antitheft door via the latch by the aid of the original key, the latch is locked in place by means of turning the front surface of the original key by a plurality of circles, worries about safety protection for doors can be solved for people, and the lock cylinder is dream scientific achievement of people and is revolution for the lock industry for all mankind.

Description

(1) Technical field [0001] The invention relates to an improved invention of various anti-theft door lock cylinders in the market.
