Abstract

The utility model provides an anti-theft alarm device which is characterized in that an insulating casing is placed in a cylinder hole; in the insulating casing, a spring, an on-off plate and a conducting ring are communicated. The conducting ring is communicated with a lock body. A key is inserted into a lock to push an insulating cylinder 5 to move to cause the on-off plate to be separated from the conducting ring. Thus an alarm circuit can alarm. The side face of a door frame is provided with a trigger polar plate which can form a closed path with the lock though conducting wires in a conducting contact plate and a hollow lock bolt. Thus the anti-theft purpose is achieved. The utility model has the advantages of simple structure and convenient installation.

Description

Burglar alarm

The utility model relates to a kind of theftproof lock and antitheft door.

Common theftproof lock and antitheft door, often existing reports to the police lags behind, and function singleness is waited to send when reporting to the police, and lockset and door has been caused destruction.

The purpose of this utility model has just provided a kind of burglar alarm, can accurately report to the police when the burglar forces open the door or opens the door with false key.

The purpose of this utility model is achieved in that

A kind of burglar alarm, form by theftproof lock, anti-picking device, warning circuit, door leaf, door cabinet etc., insulation crust 10 spinnings are in arbitrary pellet shot from a slingshot hole of lock body 1, insulation crust 10 top perforates, spring 8 is contained in the insulation crust 10, spring 8 one ends and lead 9 welding, one end of spring 8 is fixedlyed connected with break-make plate 7, the part of conducting circle 6 is enclosed within the insulation crust 10, its another part is fixed in the pellet shot from a slingshot hole, on conducting circle 6, insulation pellet shot from a slingshot 5 is placed on the bottom in lock body 1 pellet shot from a slingshot hole to spring 8 with break-make plate 7 bullets; Lead 9 and normally closed disconnect K ₃One end connects, K ₃The other end be connected on the lock body 1, and pass through relay K ₁On; Trigger pole plate 11 usefulness insulating gels 12 and be bonded in doorframe 14 one sides corresponding with door leaf 21 limits, admittance touch panel 13 is fixed in the doorframe 14, be communicated with triggering pole plate 11 usefulness leads, contact insulating base 15 is contained in the front end of hollow dead bolt 16, lead 17 is contained in the hollow dead bolt 16, the front end contact of lead 17 is fixing by contact insulating base 15, and the other end of lead 17 is connected on often to open and triggers alarm switch K ₂, K ₂The other end be connected on the lockset.

The utility model is simple in structure, easily manufacturing, easy for installation; When the burglar forces open the door or opens the door with false key, report to the police, make it to cannot succeed.

Fig. 1 is the utility model circuit working schematic diagram;

Fig. 2 is the utility model structure cut-open view;

Fig. 3 is an anti-theft lock structure amplification view among Fig. 2.

Be described further this enforcement is novel below in conjunction with drawings and Examples.

As Fig. 1, shown in Figure 3, insulation crust 10 spinnings are in arbitrary pellet shot from a slingshot hole of lock body 1, spring 8 is contained in the insulation crust 10, an end of spring 8 be connected with lead 9, the other end is welded on the break-make plate 7, the top of conducting circle 6 is contained in the insulation crust 10, the bottom is insulated shell 10 lower ends and is pressed in the pellet shot from a slingshot hole, makes it and lock body 1 conducting, and insulation pellet shot from a slingshot 5 is placed on bottom, pellet shot from a slingshot hole, form path by lock body 1, conducting circle 6, break-make plate 7, spring 8, lead 9, lead 9 is connected to normally closed disconnect K ₃One end, K ₃The other end be connected on the lock body 1.Duplex power switch 19 is contained in the lockset 20, when locking a door with key, by displacement dead bolt frame 18, makes duplex power switch 19 (K ₄) closure, dead bolt 16 also inserts lockhole, and circuit enters on the alert.When opening the door with true key, because other crown of key is higher than teeth groove, promote to regulate pellet shot from a slingshot, and promote insulation pellet shot from a slingshot 5 and move, moment breaks away from break-make plate 7 and conducting circle 6, i.e. K ₃Disconnect, cut off circuit, but because key puts in place rapidly, spring 8 makes break-make plate 7 be pressed on the conducting circle 6 again, i.e. K ₃Closure, circuit is connected, and under the effect of outage delay circuit, does not cause and reports to the police.Open door lock this moment, 18 displacements of dead bolt frame, and it is K that duplex power switch 19 is disconnected ₄Disconnect, warning circuit disconnects.When false key inserts when attempting to open, because of tooth depth is not inconsistent, then break-make plate 7 disconnects with conducting circle 6, and can not recover break-make plate 7 in the time at bounded delay and be communicated with conducting circle 6, i.e. K ₃Disconnect, report to the police so cause, insulation crust 10 and interior conduction element thereof can be placed in arbitrary pellet shot from a slingshot hole with insulation pellet shot from a slingshot 5, and the corresponding key teeth groove of pellet shot from a slingshot is deepened to the darkest datum line of teeth groove, with the effect of improving the precaution therewith.During installation, take out former pellet shot from a slingshot and spring reaming tapping gets final product.As shown in Figure 2, duplex power switch 19 is contained in the lockset 20, trigger pole plate 11 usefulness insulating gels 12 and be contained in doorframe 14 sides, to trigger pole plate 11 and 13 terminal connections of admittance touch panel with lead, when locking a door, the lead 17 that is contained in hollow dead bolt 16 is connected the front end of admittance touch panel 13, forms path, the front end contact of lead 17 is fixed on the front end of hollow dead bolt 16 with contact insulating base 15, and the other end of lead 17 is connected on often to open and triggers alarm switch K ₂On, K ₂The other end be connected on the lockset 20, when forcing open the door, any ironware touches simultaneously and triggers pole plate 11 and door leaf 21, promptly causes and reports to the police.
