Abstract

The utility model relates to a security door with an alarm device, comprising a door leaf, a door frame, a battery, the security door is characterized in that the output signal of a remote controller which is installed on the door leaf and the door frame is sent to a control circuit, the output signal of the control circuit is sent to a buzzer. The utility model is simply in structure, proper in circuit and stable in performance, when the door is opened illegally, as long as the door leaf and the door frame misplace 15mm, an alarm can automatically buzz to achieve alarm; the alarm can not stop buzzing until the power of the alarm is cut. No matter the door is opened outside or inside, after the door is closed, the alarm can not be seen and is not easy to be destroyed to achieve hiding. A DC battery is used as the power, the voltage of the power is low, and the power is not external connection type, is safe and reliable, is saving in power and durable in use.

Description

The security door of band warning device

The utility model relates to a kind of security door, particularly a kind of security door with warning device.

Existing similar security door structure, circuit are all complicated, and manufacturing cost is higher, and performance is also stable inadequately.

It is a kind of simple in structure that the purpose of this utility model is to provide, and circuit is reasonable, and is easy to use, the security door of the durable reliable band warning device of performance.

The purpose of this utility model can reach by following measure: a kind of security door with warning device, comprise door leaf, doorframe, battery, it is characterized in that: the signal that is loaded on magnetic controller output on door leaf and the doorframe is delivered to control circuit, and the signal of control circuit output is delivered to buzzer.

The purpose of this utility model can also reach by following measure: magnetic controller is divided into magnet and magnetic switch two parts, and magnet is loaded in the side frame of door leaf, and magnetic switch is loaded in the side frame of doorframe, and its position is corresponding mutually.Switch S in the control circuit ₃Pass through resistance R ₆With IC ₁1 pin and the positive pole of capacitor C link to each other IC ₁2 pin pass through resistance R ₅With magnetic switch and IC ₁3,5,9,11,13 pin join IC ₁4,6,8,10,12 pin pass through resistance R ₂Join controllable silicon S with the control grid of controllable silicon S1 ₁Anode link to each other with buzzer.

Fig. 1 is a functional-block diagram of the present utility model;

Fig. 2 is an assembly structure schematic diagram of the present utility model;

Fig. 3 is that A-A of the present utility model is to structure chart;

Fig. 4 is that B-B of the present utility model is to structure chart;

Fig. 5 is an electrical schematic diagram of the present utility model.

The utility model is described in further detail below in conjunction with accompanying drawing (embodiment):

With reference to Fig. 1～Fig. 4, the utility model comprises door leaf 1, doorframe 2, battery 3, magnetic controller 4, control circuit 5, buzzer 6 etc.Magnetic controller 4 is divided into magnet 4-1 and magnetic switch 4-2 two parts, and magnet 4-1 is loaded in the side frame of door leaf 1; Magnetic switch 4-2 is loaded in the side frame of doorframe 2; Its position is corresponding mutually.In addition battery 3, switch S ₃, buzzer 6 and wiring board 7 etc. all be loaded in the doorframe 2.

With reference to Fig. 5, when switch S ₃When placing neutral gear, whole circuit does not have battery 3 power supplies and quits work, and magnetic controller is inoperative.When owner will leave dwelling house, switch S ₃Place the work shelves, battery 3 is a line powering.At this moment, because door leaf 1 is fitted with doorframe 2, magnetic switch 4-2 connects, and circuit is ready; Behind door leaf 1 and doorframe 2 borrow 15mm, magnetic switch 4-2 and magnet 4-1 no longer have an effect, thereby disconnect, at this moment, and IC ₁4 pin output high level, make controllable silicon S ₁Conducting, thus make buzzer 6 get electric work, send chimes of doom.Only cut off the electricity supply, promptly close switch S ₃, can make just that buzzer quits work, circuit returns to original state.

The utility model has following advantage compared to existing technology:

1, simple in structure, circuit is reasonable, stable performance, and when illegally opening the door, door leaf and door Frame is as long as behind the dislocation 15mm, siren i.e. automatically buzzing, reaches alarm function; And Buzzing does not stop, until cut off the siren power supply.

2, no matter outward swinging door or inward swinging door are shut behind the door, all can't see siren, and be difficult to With its destruction, reach the effect of hiding.

3, use dc-battery as power supply, supply voltage is low, and non-circumscribed power supply, and safe and reliable, power saving is durable.

Claims (3)

1, a kind of band warning device security door, comprise door leaf (1), doorframe (2), battery (3), it is characterized in that: the signal that is loaded on last magnetic controller (4) output of door leaf (1) and doorframe (2) is delivered to control circuit (5), and the signal of control circuit (5) output is delivered to buzzer (6).

2, security door according to claim 1, it is characterized in that: magnetic controller (4) is divided into magnet (4-1) and magnetic switch (4-2) two parts, magnet (4-1) is loaded in the side frame of door leaf (1), and magnetic switch (4-2) is loaded in the side frame of doorframe (2), and its position is corresponding mutually.

3, security door according to claim 1 is characterized in that: the switch S in the control circuit (5) ₃Pass through resistance R ₆With IC ₁1 pin and the positive pole of capacitor C link to each other IC ₁2 pin pass through resistance R ₅With magnetic switch (4-2) and IC ₁3,5,9,11,13 pin join IC ₁4,6,8,10,12 pin pass through resistance R ₂With controllable silicon S ₁The control grid join controllable silicon S ₁Anode link to each other with buzzer (6).
