Abstract
The invention discloses a safety door lock with a memory function. The safety door lock comprises a panel, a lock case, a sliding strip, a limiting mechanism, a set bar, a lock cylinder and a lock cover, wherein when a door is opened, the lock cylinder is rotated so that a shifting fork can drive the sliding strip to drive the set bar to move, the set bar retracts back into the lock case, a positioning block is inserted into the limiting groove to fix the set bar so that the set bar cannot stretch out, and at this time a key is fixed to the lock and cannot be pulled out; when the door is closed, a door edge makes contact with the surface B of a limiting strip and stops the limiting strip from continuing moving, and therefore the positioning block breaks away from the limiting groove. In this way, by the adoption of the pure mechanical design, the safety door lock with the memory function has the advantages of being simple in structure, convenient to install, high in reliability and low in fault rate.
