Abstract

The utility model discloses an alarm device for an anti-picking door, which relates to an electronic alarm device, and more specifically, the utility model relates to an electronic alarm which is combined with a door and a lock. The utility model controls the connection of controlled silicon by the connection and disconnection of a door switch and a lock switch so as to achieve the alarm having a memorization function, and more specifically, contacts of two micro switches of the electronic alarm are respectively arranged on the movable positions of a door and a lock so as to form an anti-picking alarm device. The electronic alarm is composed of an alarm, the controlled silicon, the door switch, the lock switch, resistors and a power supply. The utility model has the advantages of simple structure, low cost, good alarm effect and high cost performance. The utility model can also dial the 110 for alarm by a prearranged circuit and telephone connection or be arranged on the self mobile phone, so the utility model is a safety guard for families.

Description

Pick-proof door alarm device

Technical field

The utility model relates to pick-proof door alarm device, specifically, relates to a kind of electronic alarm that combines with door, lock.

Background technology

Society is improving, and is economical in development.Along with the enhancing of the antitheft consciousness of people, pick-proof door alarm device also arises at the historic moment, and its designs and varieties are various, machinery, electronics, optics, computer, multifarious, complete; But its structure is generally all very complicated, and cost is also high.Say for consumers in general, need a kind of economical and practical pick-proof door alarm device to get final product.

Summary of the invention

The purpose of this utility model just is to provide a kind of ratio of performance to price high pick-proof door alarm device in the face of consumers in general.

The purpose of this utility model is achieved in that by the through and off of door switch, lock-switch controls the silicon controlled conducting, thereby realizes electronic warning.Specifically, the contact with two microswitches of electronic alarm is installed in respectively on the moving position of door and lock exactly, thereby constitutes a kind of pick-proof door alarm device.Wherein electronic alarm is made up of alarm, controllable silicon, door switch, lock-switch, resistance, power supply.

The utlity model has following advantage and good effect:

1. simple in structure, with low cost.

2. it is effective to report to the police: after door is shut or locked, go into as forcing open the door by force, alarm is promptly worked; At this moment, entering the room exactly pulls off door switch, lock-switch, and alarm is worked in the same old way.

In a word, ratio of performance to price height has wide application prospect.

Description of drawings

Fig. 1 electronic alarm circuit theory diagrams.

Wherein:

The Bj-alarm is selected KD01-04-01-01 for use;

The KP-controllable silicon is selected for use single-phase silicon-controlled;

G-controls the utmost point, A-positive pole, B-negative pole;

The K1-power switch is selected toggle switch KN * 220V for use ²A;

The K2-door switch is selected normally closed microswitch JW-11 for use;

The K3-lock-switch is selected for use and is often opened microswitch JW-11;

R-resistance;

The E-power supply is used the 6V dry cell, also can play the effect of warning like this when having a power failure.

Embodiment

As shown in Figure 1, its electronic component annexation of electronic alarm is as follows:

The anodal A of controllable silicon KP links to each other with the positive pole of power supply E by power switch K1, and its negative pole B links to each other with the negative pole of power supply E by alarm BJ;

Also be serially connected with door switch K2, lock-switch K3, resistance R between the anodal A of controllable silicon KP, the control utmost point G.

In addition, door switch K2 is installed on the relevant position of door, and promptly this position should guarantee that its contact move when opening the door, and connects when promptly opening the door, at closing time disconnection; Lock-switch K3 is installed in the afterbody of lock, and its contact is connected with the afterbody of the tongue of this lock, connects when guaranteeing to lock, and disconnects when unblanking.

The utility model principle of work is as follows: when door was shut, door switch K2 disconnected, at this moment door is locked, and lock-switch K3 closure, circuit just is in the warning armed state.If any forcing open the door, the people goes into, at this moment, and lock-switch K3 or closure, and door switch K2 is also closed, then the trigger electrode G of controllable silicon KP has electric current to flow through, controllable silicon KP conducting, alarm BJ work.

As belong to normal door, and promptly lock is opened with key, at this moment, though door switch K2 closure, because lock-switch K3 disconnects, then controllable silicon KP is not because control utmost point G has electricity and not conducting, and alarm BJ does not just work yet.

The utility model can also be connected with phone by preinstalled circuit to be dialed 110 and reports to the police or be arranged on the mobile phone of oneself, is the security guard of family.

Claims

1, a kind of pick-proof door alarm device, its feature are exactly that contact with two microswitches of electronic alarm is installed in respectively on the moving position of door and lock and forms, and wherein electronic alarm connects as follows by following electronic component:

The positive pole (A) of controllable silicon (KP) links to each other with the positive pole of power supply (E) by power switch (K1), and its negative pole (B) links to each other with the negative pole of power supply (E) by alarm (BJ);

Also be serially connected with door switch (K2), lock-switch (K3), resistance (R) between the positive pole (A) of controllable silicon (KP), the control utmost point (G);

In addition, door switch (K2) is installed on the relevant position of door, and promptly this position should guarantee that its contact move when opening the door, and connects when promptly opening the door, at closing time disconnection; Lock-switch (K3) is installed in the afterbody of lock, and its contact is connected with the afterbody of the tongue of this lock, connects when guaranteeing to lock, and disconnects when unblanking.
