Abstract

The utility model relates to a multi-stage alarming electronic anti-theft door. A door with a general shape is made into an interlayer shape, the door can be made of wood, artificial leather materials or fiber board materials, the middle part of the inner side of the door is provided with a movable small door on which a circuit board is arranged, and alarm circuits are distributed on the circuit board, and the multi-stage alarming electronic anti-theft door realizes the multi-stage alarm. The manufacturing cost of the anti-theft door is lower than that of the existing various anti-theft doors, and the multi-stage alarming electronic anti-theft door has good anti-theft effect and can also save large numbers of steels.

Description

Multistage warning electronic anti-theft door

The utility model belongs to member field, residential houses, particularly relates to the electronic protection door and window device that has safety measure.

The commercially available security door of China mainly contains two big classes at present: a class is the iron and steel security door made from angle steel, iron bar, iron net, this perspective in order, many resident families have all used this security door, but its cost is higher, and can only be passive antitheft, this can be described as the first generation product of security door; Another kind of is to be main by fire proofing, the Totally-enclosed-type security door that outer bread is made with steel plate, and price is also higher than the former, and better performances can be described as second generation product.Though preceding two class security doors all have theftproof performance preferably, all belong to the practice of passive defense, the utility model proposes a kind of electronic anti-theft door, it is not only to be to stop the robber to enter, but actively reports to the police, and then catches the robber.

The purpose of this utility model is to utilize electronic technology that multistage warning device is installed on the common, inexpensive door, give the uninvited guest warning with burst, make it timid and give up, do not listen warning to continue crime as it, before it is not opened door, electronic anti-theft door can send loud and clear alarm song automatically, startles the neighbours, and then the robber is arrested.

The utility model is realized by following technical proposals: with the door of a fan common shape, plank, artificial leather or other any fiberboard quality all can, be made into sandwich-like, the door middle inside has the wicket of an activity, a circuit board is housed on the wicket wall, be furnished with warning circuit on the plate, the terminal plain conductor that has a bit of induced signal to use that reveals of circuit is equipped with loudspeaker in the door-plate interlayer.Respective doors has ommatidium outside the branch, the tongue tube that doorbell and four control circuits of G1-G4 are closed also is equipped with on the next door, they are connected with appropriate section in the alarm circuit by lead respectively, in the door-plate outside go up can be routinely door, be furnished with inside and outside handle, tapered end and peephole respectively.

Further specify embodiment in conjunction with the accompanying drawings:

Description of drawings:

Fig. 1 is the wiring schematic diagram that is furnished with multistage warning circuit;

Fig. 2 is the power circuit part that can use the resistance-capacitance circuit instead of transformers;

Fig. 3 electronic anti-theft door outer side view;

The local figure of the inboard little dodge gate part of Fig. 4 electronic anti-theft door.

The schematic diagram of circuit board (1) comprises four partial circuits, power circuit part (1-1), wherein civil power step-down transformer step-down, for avoiding heavy, also can be without transformer, and replace by resistance-capacitance circuit (seeing shown in Figure 2), warning circuit (1-2) triggered, wherein comprise integrated IC1, IC2, also have two normally closed dry reed pipes of G2, G3, the effect of G2 to be, tongue tube breaks away from the attraction of the little magnetic stripe B of embedding on the doorframe and conducting when door is opened, alarm circuit work, loudspeaker are rung.The effect of G3 is, if the robber is for anti-antitheft and searching for outdoors with magnet, seek office, make alarm not during sounding by attraction, do not know its accurate position as the thief, in case the road is when the G3 position, can make alarm buzzer sound your writing, in use, also G3 can be omitted, not influence other warning effect.Doorbell circuit (1-3) includes integrated IC3 of ding-dong sound equipment; Induction phonation circuit (1-4), comprise two integrated IC4, IC5, the end also includes one section line of induction (1-5), and this four partial circuits layout is on a circuit board, and be assemblied in above the wall (6) of wicket, wicket wall (6) can lean on loose-leaf or screw to be connected with gate panel (8) inboard.A section lead that exposes is as miniature antenna, induced signal, if any the close security door of thief, three, in 40 centimeters the scope eavesdropping room during sound, this lead makes the sensor circuit sounding with induced signal, it can be a song, also can make the sound of barking, this is to warn the thief beyond this point, can false sense not answer and the formation interference for the neighbour who passes by on one's way, do not listen advice still will force open the door as the thief, when touching door lock (2), touch even if put on one's gloves, loud and clear sound just takes place in touch alarm buzzer in the door automatically, just in case this one-level alarm is not triggered and causes sound, when it pries open security door,, make the effect of reed pipe G2 dry up as long as door reaches little angle (as 15 ° or 20 °), alarm buzzer surely can big automatically acoustic alarm, and the thief dare not continue to prize the cell gate of the inside in the case.

The all shared same loudspeaker of microphone device in the three part circuits (3) mainly are contained in the upside of door-plate (8), and doorbell (4) is installed in the upper right side, and peephole (5) is contained in the sight line convenience.

The sensitivity of induction phonation circuit is adjustable, only needs to change the adjustable electric resistance and gets final product.

The power supply of circuit is the alternating current-direct current dual power supply, having the people only to use at ordinary times in the family exchanges, when going out, the household can connect battery, also can charge the battery this moment, and ammeter V measures cell voltage usefulness, and the user also can omit this ammeter, because some corridor ammeter and plug-in strip are outdoors, even if earlier with the plug-in strip outage, owing to have battery, circuit still can operate as normal before crime for the thief.

Induction phonation circuit and touch alarm all have switch, (come in and go out such as the household) when not needing it to report to the police, and can turn off power switch (7) at any time, only stay through battery powered electronic door bell.

Trigger G1 and the G4 that responds in the phonation circuit (1-4) in the warning circuit (1-2), be the open type tongue tube, the people on one's own side can be placed on correspondence position outdoors with small magnet, can disconnect above-mentioned two partial circuits, touches rule for preventing that the thief from changing to, and its position can change.

This electronic anti-theft door has been realized Multi-stage alarming, the thief near door-plate when eavesdropping, touch During lockhole, when prying open a crack, all can report to the police respectively each that this electronic anti-theft door is used Individual parts also can be contained on all kinds of antitheft doors of present production, as use producing wood, and cost will Obviously cheaper than existing all kinds of antitheft doors, good anti-theft effect also can be country and saves big dimension Material.
