The utility model has the characteristics of simple structure, practicality, reliability, convenient installation, convenient maintenance, low cost, etc.; the connecting wire does not need to pass through the door plate, the door lock does not need to be changed, and the utility model can be used both alone and by connecting with buildings and communities by the network.
Description
The utility model relates to a kind of anti-theft alarming control device, especially a kind of anti-theft alarming control device that is arranged on the door lock.
The household door lock burglar alarm of Chinese patent ZL96237862.3, microswitch in its anti-theft warning circuit need be fixed on the inside of door lock, and need passing doorframe, the connecting line of circuit could be connected with microswitch with door-plate, its weak point is: 1, need door lock special or repacking, thereby the increase cost, installation, maintenance inconvenience; Thereby 2, need damage the structure at gate itself in the door-plate perforation, influence the attractive in appearance of gate and reduce degree of safety; 3, the connecting line of microswitch often waves, and the possibility that pine is disconnected or open circuit takes place easily, influences the effect of using and report to the police, reduction of service life; Time of fire alarming is oversize, needs outage could remove warning etc.
The purpose of this utility model be exactly provide in order to overcome above-mentioned weak point a kind of simple in structure, need not change big Door and its lock, can delayed alarm and the low theftproof alarm door lock control device of cost.
The purpose of this utility model realizes by following scheme: the K switch 2 in the alarm control circuit is installed in the snap close shell 1 place corresponding with dead bolt 3, K switch 1 can be installed in the snap close shell 1 or near any one position doorframe and the doorframe, and K switch 1, K2 are connected in series.K switch 1, K2 can adopt microswitch, travel switch or remote control switch.The connecting line of K switch 1, K2 can be built in the doorframe or along the wiring of doorframe limit, need not pass door-plate and change door lock.Alarm control circuit of the present utility model also comprise the delay circuit 6 that constitutes with elements such as integrated circuit of clock IC1 and with the execution relay J 2 of the antitheft network systems connection in building or sub-district.
Characteristics of the present utility model are: simple in structure, practical, reliable, need not change door lock and door-plate, and installation, maintenance is convenient, both can use separately also and can use with building or cell networking, and cost is low etc.
The utility model will be further described below in conjunction with accompanying drawing:
Fig. 1 is the utility model anti-theft warning circuit schematic diagram on the alert.
Fig. 2 is the utility model two flapper lock warning schematic diagram on the alert.
Fig. 3 is that the two flappers of the utility model are locked the view that drops one's guard.
Fig. 4 is the utility model list flapper lock warning schematic diagram on the alert.
Fig. 5 is that the utility model list flapper is locked the view that drops one's guard.
Fig. 6 is the utility model glass door special door lock schematic diagram on the alert of reporting to the police.
Fig. 7 is the utility model glass door special door lock view that drops one's guard.
Referring to Fig. 1~Fig. 3, when using two tongue locks (embodiment one), when the utility model was locked at door lock 2, promptly main dead bolt 4 and secondary dead bolt 3 put in the snap close shell 1 simultaneously, at this moment, K switch 1 closure, K switch 2 disconnects, and it is on the alert that the utility model is entered, when the situation of forcing open the door or forcing open the door takes place, when as long as secondary dead bolt 3 leaves 3~5 millimeters on doorframe, K switch 2 demand workings, by power circuit 5 to alarm Y power supply and make its sounding alarm; After door was opened fully, K switch 1 disconnected, but because the time-lag action of delay circuit 6 makes alarm Y continue within a certain period of time to report to the police, the length of time of fire alarming can decide by the resistance of regulating adjustable resistance R.Meanwhile, carry out also energising action simultaneously of relay J 2, make the antitheft network system in building or sub-district sounding alarm simultaneously.If the connecting line of K switch 1, K2 and relay J 1 is cut off, at this moment, relay J 1 outage discharges, and contact J1 ' adhesive is connected, and makes the utility model sounding alarm equally.If normally unblank, main dead bolt 4 is return the inner chamber of door lock 2, and at this moment, K switch 1 disconnects, and it is on the alert that the utility model is automatically terminated, thereby, can sounding alarm.
Referring to Fig. 4~7, if that uses single flapper lock or glass door special use is contained in ground door lock (embodiment two, three), K switch 2 is installed in the snap close shell 1 place corresponding with dead bolt 3, and K switch 1 can adopt the remote control switch (not shown), is installed near any one position of doorframe or doorframe.In the time of on door lock, dead bolt 3 puts in the snap close shell 1, and K switch 2 disconnects, and adopts remote control mode with K switch 1 closure, and the utility model promptly enters on the alert, as long as dead bolt 3 leaves 3~5 millimeters on doorframe, K switch 2 is connected, and alarm Y sends alarm signal immediately.If normally unblank, disconnect K1 earlier, the utility model state that promptly drops one's guard.
Claims (2)
