Abstract

The utility model discloses a door lock which can prompt the opening and closing of a house door. The door lock which can prompt the opening and closing of a house door is characterized in that an elastic movable plate is arranged inside the blocking shell of the lock tongue of the common hidden lock of a house door and is positioned on the blocking opening of the lock tongue. Electric contact points are respectively arranged on the movable plate and on the inner side of the blocking shell of the lock tongue, and the two electric contact points are mutually corresponding. The two corresponding electrical contact points are used as control switches to be connected with a sounder or the circuit of a doorbell by conducting wires. When the house door is tightly locked, the sounder or the doorbell does not sound. When the house door is opened or falsely locked, the sounder or the doorbell sounds to prompt that the house door is not be tightly locked.

Description

Door lock with pointing

The utility model belongs to a kind of door lock of pointing out door to open and close.

Existing door lock is not owing to be provided with the device that the prompting door opens and closes, and when neglecting locking the door or door when being in " empty lock " state, is difficult for being discovered by house-owner people, makes it to cause the room property stolen.

In view of the foregoing, the purpose of this utility model provides a kind of door lock of pointing out door to open and close.

The purpose of this utility model is achieved in that being positioned at dead bolt retaining mouth in the dead bolt retaining shell of common door built-in lock is provided with an elastic movable plate, on this portable plate, be respectively equipped with electric contact with dead bolt retaining shell inboard, and both electric contacts are corresponding mutually, and the electric contact of two correspondences links to each other with a sounder or doorbell circuit through lead as gauge tap.When door is in unlatching or empty lock state (dead bolt does not stretch in the dead bolt retaining mouth fully), the electric contact on the elastic movable plate contacts with the electric contact of dead bolt retaining shell inboard, and sounder sends alarm sound, and prompting house-owner people door does not have locking; When door was in locking state, dead bolt backed down elastic movable plate, and the electric contact on the portable plate is separated with the electric contact of dead bolt retaining shell inboard, and this moment, sounder was not sounded, that is the explanation door is locked.

The utility model is owing to be provided with the device that a prompting door opens and closes on common door built-in lock, thereby can guarantee to lock door, stops to neglect locking the door or the generation of empty lock phenomenon.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is the utility model structural representation.

Fig. 2 is the utility model circuit theory diagrams.

By accompanying drawing as can be known, the baffle plate 5 that elastic movable plate is connected as a single entity by the turning cylinder 4 that places both sides in the dead bolt retaining shell 2 with this turning cylinder and be enclosed within on the turning cylinder and torsion spring 8 that its two ends are connected in baffle plate and dead bolt retaining shell inboard respectively constitutes, baffle plate 5 is positioned at dead bolt retaining mouthful 3 places, the electric contact 6 which is provided with 7, two correspondences of dead bolt retaining shell 2 inboard electric contact 6 corresponding electric contacts links to each other with electronic door bell 9 by lead respectively with 7.When dead bolt 1 backs down baffle plate 5, two electric contacts 6 and opening in 7 minutes, doorbell 9 is sounding not, shows that door locks this moment; Dead bolt 1 does not back down baffle plate 5, and then two electric contacts 6 and 7 contact, doorbell 9 sounding, the not locking of prompting door.

Claims

1, a kind of Door lock with pointing, it is characterized in that being positioned at dead bolt retaining mouth in the dead bolt retaining shell of common door built-in lock is provided with an elastic movable plate, on this portable plate, be respectively equipped with electric contact with dead bolt retaining shell inboard, and both electric contacts are corresponding mutually, and the electric contact of two correspondences links to each other with a sounder or doorbell circuit through lead as gauge tap.
