Description

Burglar alarm door-bell lock

The utility model relates to a kind of safety door latch, particularly a kind of door lock that has burglar alarm and answer objective doorbell effect.

In the prior art, a kind of dual fail-safe door lock is arranged, be equipped with in its lock housing tapered end control and have lock insure the tongue piece of safety effect, except in addition dark tongue piece interlock by above-mentioned tongue piece and play the dual fail-safe effect.This dual fail-safe door lock uses more common door lock safety, but still is a kind of mechanical type safety door latch, can not play burglar alarm and answer objective doorbell.

The purpose of this utility model is to provide a kind of safety door latch that has electronic device and audio device, and it not only has the function of mechanical double insurance lock, and can play burglar alarm and answer objective doorbell.

For achieving the above object, the utility model adopts following technical proposals: this door lock includes lock housing, be inserted in tapered end in the door-plate, be placed in tongue piece, the dark tongue piece in the lock housing and have the lock protector of dialling handle.Be characterized in: the music door-bell CMOS integrated package and the warning CMOS integrated package that connect power supply are housed in lock housing, music door-bell CMOS integrated package is by the bell button control that is installed on the door-plate, warning CMOS integrated package is by group handle Collaborative Control of dark tongue piece and lock protector, and two CMOS integrated packages connect a shared loudspeaker.Its operating principle is: the mechanism of its existing dual fail-safe door lock keeps in this door lock, therefore has dual fail-safe door lock original function equally, added bell button, music door-bell CMOS integrated package and speaker system, the guest presses the F bell button, then music door-bell CMOS integrated package is connected power supply, loudspeaker is connected in its output, makes loudspeaker send the music sound.Added dark tongue piece and lock protector are dialled handle Collaborative Control warning CMOS integrated package and speaker system, when coming the rotation lock protector, robber's key unlocking of no use dials handle thereby inoperative, and when directly door being pried open, dark tongue piece ejects under spring action and works, it is inoperative inharmonious that its effect and lock protector are dialled handle, the CMOS integrated package of then reporting to the police is connected power supply, and loudspeaker is connected in its output, and loudspeaker is given the alarm.When owner has opened door with key, the lock protector dial handle rotate work and also dark tongue piece because door has been opened also works, both synergies make warning CMOS integrated package disconnect power supply and do not report to the police.

The music door-bell CMOS integrated package of this door lock can adopt the COMS-KE integrated package of market sale, warning CMOS integrated package can adopt the COMS-KD integrated package of market sale, power supply can adopt the dry cell of two series connection, and No. 5 batteries as market sale are installed in the lock housing.

The dark tongue piece of this door lock with the circuit of dialling handle Collaborative Control warning CMOS integrated package can be: on warning CMOS integrated package is connected any circuit in two circuits of power positive cathode, connecting one by the normally closed switch of dark tongue piece control and one by dialling the normal open switch that handle is controlled, normally closed switch is installed in after the dark tongue piece inner end, and normal open switch is installed in before the lock protector of tongue piece below.

The utility model has conspicuous advantage compared with prior art: it not only has the security insurance function of mechanical double insurance lock, and have burglar alarm and a function that should objective doorbell, door lock, warning and three of doorbells are combined together, compact conformation, function is complete.

The drawing of accompanying drawing is described as follows:

Fig. 1 is an internal construction schematic overview of the present utility model.

Fig. 2 is the utility model face view outdoors when being installed on the door.

Fig. 3 is a circuit diagram of the present utility model.

An optimum implementation of the present utility model is: referring to Fig. 1 and Fig. 2, this door lock includes a lock housing 1, be inserted in tapered end 14 in the door-plate, be placed in tongue piece 7, the dark tongue piece 5 in the lock housing 1 and have the lock protector 9 of dialling handle 3.Rear section in the lock housing 1 is equipped with loudspeaker 2, two No. 5 dry cells 12, music door-bell CMOS integrated package 10 and warning CMOS integrated packages 11, after dark tongue piece 5 inner ends, a normally closed switch 4 is installed, a normal open switch 8 was installed, near installation bell button 13 door-plate external surface dress tapered end 14 before the lock protector 9 below the tongue piece 7.

Referring to Fig. 3, the circuit connecting mode of this door lock is: the positive pole of battery 12 is by the anodal input adapter of series connection normally closed switch 4 and normal open switch 8 CMOS integrated packages 11 taking alarm, and battery 12 positive poles connect the anodal input adapter of music door-bell CMOS integrated package 10 by bell button 13.The negative pole of battery 12 directly connects the negative pole input adapter of warning CMOS integrated package 11 and music door-bell CMOS integrated package 10.The output and power supply 12 negative poles of warning CMOS integrated package 11 and music door-bell CMOS integrated package 10 directly are connected loudspeaker 2.

Its operating principle is: after owner locks a door, dial handle 3 towards the place ahead (among the figure shown in the dotted line), normal open switch 8 is dialled handle 3 compressings and closure, dark tongue piece 5 owing to shut inwardly is compressed and contracts (among the figure shown in the dotted line), its rear end compressing normally closed switch 4 is opened normally closed switch 4, circuit between warning CMOS integrated package 11 and power supply 12 negative poles is obstructed, and loudspeaker does not ring.If the robber forces open the door, owing to there is not group handle 3 of key turns lock protector 9, normal open switch 8 still is in closure state, when door is pried open a seam, dark tongue piece 5 is under the effect of spring 6 and eject, so normally closed switch 4 is removed compressing power and closure, the circuit of reporting to the police this moment between CMOS integrated package 11 and power supply 12 negative poles is connected, and loudspeaker sends the warning sound.If owner turns the key in the lock, group handle 3 of key turns lock protector 9, normal open switch 8 is removed compressing power and is opened, though make normally closed switch 4 closures owing to dark tongue piece 5 ejects when door is opened, circuit between warning CMOS integrated package 11 and power supply 12 negative poles is still obstructed, and loudspeaker can not send the warning sound.When the guest pressed bell button 13, circuit was connected and loudspeaker 2 sends the music door-bell sound between music door-bell CMOS integrated package 10 and power supply 12 negative poles.

The utility model is applicable to the door of each hotel and dwelling house.
