Description

A kind of automatic alarm anti-theft door

Technical field

The utility model relates to a kind of security door, particularly relates to a kind of security door that can report to the police automatically.

Background technology

Mostly security door on the existing market is to form with steel or other material manufacturings of comparing hard, and reinforce layer by layer, in order to obtain better anti-theft effect, need also to add that various locks guard against, the main shortcoming of such security door is to need a large amount of steel or other expensive materials, and the expense of required cost is not low naturally, if the user is before if not the security door that uses, then need to reinstall new security door, input ratio is bigger.

The utility model content

The purpose of this utility model provides a kind of easy for installation and security door that can report to the police automatically.

The purpose of this utility model realizes by following technical proposal: a kind of automatic alarm anti-theft door, comprise door and lock, also comprise pitman, an alarm, be connected a circuit on the alarm, be connected with a micro power on the circuit, wherein alarm and circuit and micro power all are fixed on the doorframe or on the wall, circuit has two isolated contacts, one end of pitman is connected with lock and moves with the unlatching of lock, the other end of pitman can contact simultaneously with two contacts, and this moment, circuit was in connection.When door is opened, no matter opening the door from outdoor use key turns lock still is to unblank indoor, pitman can be with the rotation of lock away from two contacts, when door is in when closing, pitman can reset to the position very approaching with the distance of two electric shocks, if do not push the door open by unblanking, thereby pitman will just contact connection circuit with two contacts simultaneously when door is opened any, and this is that alarm will ring.

From architectural feature of the present utility model as can be seen, advantage of the present utility model is: simple in structure, and easy for installation, cost is low, also can install on common door and allow a common door become an extraordinary security door of theftproof performance, automatic alarm anti-theft door of the present utility model is safe and reliable.

Description of drawings

Fig. 1 is a structural representation of the present utility model

Wherein Reference numeral 1 is that door 2 is that doorframe 3 is that lock 4 is that pitman 5 is that alarm 6 is that circuit 7 is that micro power 8 is contacts

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described further:

Preferred embodiment

A kind of automatic alarm anti-theft door as shown in Figure 1, comprise door 1, doorframe 2 and lock 3, also comprise a pitman 4, alarm 5, be connected a circuit 6 on the alarm 5, be connected with a micro power 7 on the circuit 6, wherein alarm 5 and circuit 6 and micro power 7 all are fixed on the doorframe 2 or on the wall, circuit 6 has two isolated contacts 8, one end of pitman 4 is connected with lock 3 and moves with the unlatching of lock 3, the other end of pitman 4 can contact simultaneously with two contacts 8, and this moment, circuit 6 was in connection.When door 1 is opened, no matter opening the door from outdoor use key turns lock 3 still is to unblank 3 indoor, pitman 4 can be with the rotation of lock 3 away from two contacts 8, when door 1 is in when closing, pitman 4 can reset to the position very approaching with the distance of two contacts 8, if 3 do not push the door open 1 by unblanking, thereby pitman 4 will just contact connection circuit 6 with two contacts 8 simultaneously when door 1 is opened any, and at this moment alarm 5 will ring.
