The invention provides a lock core structure with both safety escape and anti-theft, especially a lock key or a foreign object is inserted into the lock core on the outer side, and when the key is inserted on the inner lock core, the first driving block can be pushed. The part pushes against the second actuator, forcibly pulling the second actuator away from the transmission slot, so that the outer lock core will idle, and the inner person can turn the lock core to unlock the escaper.

Press, in conventional locks, the key is used to unlock the lock in both directions. Most of them are designed to unlock the lock core by turning only one end at a time. When the key is inserted into the lock core, the key will push a transmission block to connect the lock. In the cam, the key can be unlocked by driving the lock core. However, when the transmission block at one end is connected to the cam, it will push against the transmission block at the other end, which will cause the other end key to not be fully inserted into the lock core. While unlocking, although the principle of its components can achieve the effect of anti-theft, a major shortcoming of this design is that when the outer key is inserted by a key, the key on the inner key cannot be inserted into the key. The unlocking is that if such locks are used in public places such as homes, medical institutions, or schools, if people outside the house accidentally or deliberately insert the key into the outer lock core, it will cause indoor personnel to The key is still unable to be inserted into the lock and unlocked. If an emergency occurs at this time, such as the accident of an indoor person, need to be rescued, escape or send to the hospital, it will lead to the inability to escape the room because the lock cannot be unlocked. Need Please also assist the staff located outdoors. This will lead to missed golden rescue and escape time. If an emergency such as a fire is involved, the consequences will be disastrous.

In addition, in terms of anti-theft properties, in European Patent No. EP 2679749 B1, although the lock portion of the stopper can be extended into the recess of the second transmission block after the lock is damaged, the anti-theft is achieved. However, when a thief destroys the lock core, the lock core is rotated first, and then the lock core is removed, which will cause the recessed hole of the second transmission block to be unable to align with the stopper portion, so the stopper portion cannot The second transmission block was locked and cracked, so its anti-theft property was still missing.

1. When the present invention is unlocked from the outside, the transmission member of the second transmission is entered into the transmission slot when it is opposite to the transmission slot, so that the second stopper can pass through the second transmission to Driven by the cam, and when the key on the inside is inserted, the pushing portion of the first driving block will push against the second The actuator causes the second actuator to be forcibly pulled away from the transmission slot, so that the outer lock core will idle, and the first actuator on the inner side is pushed by the elastic force of the inner spring. It can be unlocked by reaching into the transmission slot by being driven by the cam. Therefore, personnel located inside the door can be unlocked regardless of whether there is a key or foreign object inserted in the outer lock center, so as to facilitate the emergency Personnel can unlock to escape. However, when a key is inserted from the inside, the outside lock core will be idled, so even if the outside person has the correct key, it cannot be unlocked, so as to achieve safe escape and anti-theft.

2. The present invention can increase the torque of the lock core transmission to the second stopper block or the first stopper block by the setting of the transmission plate, so as to facilitate the user to rotate the cam through the key, thereby preventing the door from being stressed. When the thermal expansion or contraction of the temperature difference deforms the cam, it is difficult to rotate the lock when the cam is caught by the wall surface of the door hole of the door frame.

3. The second stopper block of the present invention is provided with a plurality of connection holes corresponding to the stopper tip to prevent the conventional thief from destroying the lock core, and only a slight rotation of the lock core will prevent the stopper tip from being assembled. The problem is that the anti-destructive function is invalidated when it is connected to the assembly hole.

At this time, the first transmission block 32 is forced to move in the direction of the cam 2 to press the inner spring 34, and at the same time, the pushing portion 321 is passed through the perforation. 332 pushes against the abutting portion 432 of the second transmission 43 to cause the second transmission 43 to press the outer spring 44 and disengage the transmission member 431 from the transmission groove 21 so that the outer lock core 5 is even After being rotated, it can't be unlocked by being transmitted to cam 2. Therefore, users located on the inside can achieve an excellent anti-theft effect. In addition, the transmission groove 21 of cam 2 in Figs. 11 and 12 is not aligned with the transmission. Block 331, therefore, the inner spring 34 will be further compressed, and the transmission block 331 is against the side edge of the cam 2 to rotate the inner lock core 5 so that the lock core 5 is transmitted to the first transmission block through the assembly 54 32, and the first stop block 31 is transmitted through the transmission piece 52, so that the first stop block 31 is transmitted through the groove 412 A first actuator drive block of 33,133, so that when the drive block 331 pairs of drive slot 21 is located, i.e. the inner achieve the unlocked position, as in the first As shown in Figures 13 and 14, the first transmission 33 is pushed by the elastic force of the inner spring 34, so that the transmission block 331 extends into the transmission groove 21, so that the inner lock core 5 can pass through the first The stopper 31 and the first actuator 33 are driven by the cam 2 and continue to rotate the cam 2 to unlock, so that the outer lock core 5 does not affect the inner lock core 5 for the cam 2 even if the key 6 or foreign body is inserted into the group. Therefore, when it is necessary to escape in an emergency such as a fire, the user located on the inside can easily unlock and escape by turning the key 5 on the inside, so as to prevent delay in rescue and escape. To achieve the effect of safe escape.

It should be particularly noted that when the key 6 on the outside is not inserted into the lock core 5, the key 6 ′ is inserted directly on the inside of the lock core 5.
