Multifunctional safety door lock
The invention discloses a multifunctional safety door lock. A driven gear and a stop gear disc for locking the rotation, which are integrated in the axial direction, are installed in an outer shell, a locking device is perpendicularly arranged above the stop gear disc, an upper toothed column and a lower toothed column of the locking device are engaged with each other in the axial direction, the lower top end of the lower toothed column is matched with a wheel toothed groove of the stop gear disc, a pressure cap at the top end of the upper toothed column stretches out to be above a limiting sleeve, a ringing bell cavity is formed between a baffle plate and a positioning plate, a ringing bell is installed in the ringing bell cavity, a falciform rack which is linked with a lock pin is engaged with the driven gear, the free end of the lock pin can rotate up and down, after the lock pin rotates downwards to push against the floor, the opening of a door body is locked, and a door opening warning effect and an antitheft effect can be realized when the door is opened; when the lock pin forms a right angle together with the positioning plate, the lock pin and a wall door stopper seat attract each other to position the door body, and the door body is prevented from being forcibly closed by the wind.
