Description

Hook alarm door bell lock

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

In the prior art, a kind of Warning door bell lock that has oblique tongue and uvula is arranged, can play burglar alarm and answer objective doorbell effect.But it only is applicable to single open-door, and is then inapplicable for double door.

The purpose of this utility model is to provide a kind of improved Warning door bell lock, not only is applicable to single open-door, also is applicable to double door.

For achieving the above object, the utility model adopts following technical proposals: the utility model is the same with prior art to include lock housing, be inserted in tapered end and the tapered end on the lock housing in the door-plate, be placed in the square tongue in the lock housing, oblique tongue and uvula.Be characterized in: be equipped with in the lock housing and connect electronic installation power supply, that form by music door-bell CMOS integrated package and warning CMOS integrated package, wherein 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 square tongue and uvula Collaborative Control, and two CMOS integrated packages connect a shared loudspeaker; Retractable hook tongue is equipped with in the both sides up and down of side's tongue front end.When locking a door, square tongue stretches out and when inserting auxiliary lock body, and the square tongue front end hook tongue of both sides up and down stretches out and hooks auxiliary lock body; When unblanking, in the hook tongue side of the being retracted to tongue.So the utility model not only is applicable to single open-door, and be applicable to double door.

Hook tongue of the present utility model is hinged by pin and square tongue, and hook tongue rear inside is supported by stage clip; There is the hook with the auxiliary lock body coupling in the hook tongue front end outside, and there is the hook with the lock housing matching effect in the outside, rear end.When square tongue stretched out, the hook of hook tongue rear end was run into lock housing and the hook tongue is stretched out, and then the hook of its front end just hooks auxiliary lock body; When square tongue indentation, the stage clip of hook tongue rear end works, and makes in the hook tongue side of the being retracted to tongue.

Electronic installation in the utility model is made of power supply, doorbell switch, uvula gauge tap, square tongue gauge tap, warning CMOS integrated package, music door-bell CMOS integrated package, four triodes, two diodes, three resistance, three electric capacity, coil and loudspeakers.Power supply adopt two No. five dry cells, doorbell switch be installed in bell button, uvula gauge tap on the door-plate adopt often open microswitch, square tongue gauge tap adopt often drive microswitch, warning CMOS integrated package adopts commercially available KD-9561 type integrated package, music door-bell CMOS integrated package to adopt commercially available TM-802C type integrated package, loudspeaker to adopt commercially available HTD-27 type piezoelectric ceramic piece.When locking a door, square tongue stretches out, and then the microswitch of its control cuts out; Uvula is pressed into, and then the microswitch of its control is opened, and the obstructed and loudspeaker of warning circuit does not ring.When door was pried open by the robber, uvula ejected and the switch of its control cuts out, and then warning circuit is connected and reported to the police.When owner turns the key in the lock, square tongue indentation and the microswitch of its control is opened, uvula stretches out and the microswitch of its control cuts out, and warning circuit is obstructed and do not report to the police.The guest presses the bell button on the door-plate, and then doorbell switch is closed, and doorbell circuit is connected and sent the tinkle of bells.

The utility model compared with prior art, have conspicuous following advantage: the utility model makes insurance safety door latch, burglar alarm and should combine together by three of objective doorbells, compact conformation, and function is complete, not only be applicable to single open-door, and be applicable to double door.

The drawing of accompanying drawing is described as follows:

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

Fig. 2 is a profile elevation of the present utility model.

Fig. 3 is a profile vertical view of the present utility model.

Fig. 4 is that the utility model is installed view on door-plate.

Fig. 5 is a circuit diagram of the present utility model.

An optimum implementation of the present utility model is: referring to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, this hook tongue Warning door bell lock includes lock housing 17, be inserted in tapered end 22 in the door-plate and the tapered end 20 on the lock housing, the chamber side of the arrangement tongue 14 that constitutes at lock housing 17 and base plate 1, tiltedly tongue 4 and uvula 8 and electronic installation 2.Interlock side's tongue 14 moves as horizontal direction by " V " shape groove of square tongue 14 rear end side's hyoplastrons for the rotation interlock finger 6 of two tapered ends 20,22, finger 6.Retractable hook tongue 12 is equipped with in the both sides up and down of side's tongue 14 leading sections.Hook tongue 12 is hinged by pin and square tongue 14.Hook tongue 12 rear inside are by stage clip 11 supporting, and there is the hook with the auxiliary lock body coupling in the hook tongue 12 front ends outside, and there is the hook 13 with lock housing 17 matching effects in the outside, rear end.Two microswitches 9,10 are housed on the lock housing 17, and microswitch 10 is by 15 controls of the compressing tablet on the side's of being installed in tongue 14, and microswitch 9 is by uvula 8 rear end crotch controls.There are stage clip 7 supportings at uvula 8 rear portions.A hinged connecting rod 5 on the square hyoplastron of side behind the tongue 14, connecting rod 5 drive oblique tongue 4 and move as horizontal direction, and tiltedly there are stage clip 3 supportings at tongue 4 rear portions.The mobile of finger 6 can stir connecting rod 5, and makes oblique tongue 4 indentations.Tiltedly the tongue rearward end has the handle 18 of bending extension to lock housing 17, can pull and make oblique tongue 4 indentations.Tiltedly locking plate 16 is equipped with in below, tongue 4 rear ends, can rotate the knob 19 of lock housing 17 outsides and make and move on the locking plate 16, thereby the upper end of locking plate 16 is stuck in the rear end of oblique tongue 4 and makes not retractable of oblique tongue 4.Bell button 21 is housed on door-plate, and handle 23 opens the door in the below.
