Description
Technical Field
The invention relates to a lock core structure with functions of safe escape and theft prevention, in particular to a lock core structure which can enable a pushing part of a first transmission block to push against a second transmission when a key is inserted into an inner lock core no matter whether the lock core positioned at the outer side is inserted with the key or not, so that the second transmission is forcibly dragged away from a transmission groove, the lock core at the outer side can idle, and personnel at the inner side can rotate the lock core to unlock and escape.
Background
In the existing lock, the lock key is used for unlocking in both directions, most of the existing locks are designed to be capable of unlocking by rotating the lock core at one end only once, when the lock key is inserted in the lock core, the lock key pushes a transmission block to be assembled in a cam, so that the lock key can drive the lock core to unlock, however, when the transmission block at one end is assembled in the cam, the transmission block at the other end is pushed, so that the lock key at the other end cannot be completely assembled in the lock core to unlock, although the principle of the components can achieve the anti-theft effect, the important deficiency of the design is that when the lock core at the outer side is inserted in the lock key, the lock key at the inner side cannot be really assembled in the lock core to unlock, so that if the lock is applied to public places such as families, medical institutions or schools, if the outside personnel carelessly or intentionally inserts the lock key in the lock core at the outer side, the indoor personnel cannot be assembled in the lock core to unlock even if the correct lock key, if an emergency occurs, such as an accident of indoor personnel, a need for rescue, escape or medical service, the indoor personnel cannot escape from the room due to the fact that the indoor personnel cannot be unlocked, and the personnel located outdoors need to assist, the gold rescue and escape time is missed, and if the emergency such as a fire disaster is attempted, the consequences are unreasonable.
In addition, for the anti-theft property, although the lock is destroyed, the abutting part of the locking pin can extend into the concave hole of the second transmission block to achieve the anti-theft effect, when the lock core is destroyed by a thief, the lock core is rotated first and then removed, which results in that the concave hole of the second transmission block cannot be aligned with the abutting part, so that the abutting part cannot lock the second transmission block to be cracked, and the anti-theft property is still lost.
