Description

A kind of intrusion detection device

Technical field:

The utility model belongs to the burglar alarm technical field.

Background technology:

Anti-theft safety door is being extensive use of the core-inset type theftproof lock at present.Anti-" technical opening " ability of this lock is low.The invador can unblank to enter the room at short notice, so its anti-theft capability is undesirable.

" warning " is the effective measures that improve anti-theft capability, but this lock is not possess warning function.

Existing burglar alarm, the intrusion detector that they adopt is " magnetic switch " and " infrared "." magnetic switch " has only as the invador and pushed the door open, just start and report to the police." infrared " also has only the invador to enter just startup warning in the door.What therefore they were realized is that " hysteresis quality " reports to the police, and anti-theft effect is undesirable.

The utility model content:

The purpose of this utility model provides a kind of straightforward procedure that makes the core-inset type theftproof lock have warning function---and switch enclosure and this kind lock with one " magnetic switch " are formed an intrusion detection device.What its detection was descended is the origination action that the invador unblanks to cross the threshold, and has realized that " in-advance " warning---lock is not opened as yet and just reported to the police, and has improved the warning effect significantly.Improved anti-theft capability.

The utility model is achieved in that

A kind of intrusion detection device of the utility model is made up of switch enclosure 1 and core-inset type theftproof lock 3 two parts of magnetic switch, and is middle with lead 2 connections, asks for an interview Fig. 1.

Used magnetic switch 1 is the D type, just the moving fault contact.Switch enclosure 1 is loaded on the wainscot of entry door door leaf.

Core-inset type theftproof lock 3 is present theftproof locks most widely used on security door, and it is a side that is loaded on the inner chamber between external door panel in the security door.The used existing common core-inset type theftproof lock of theftproof lock 3 usefulness of the utility model is changed a social system to form---installed a microswitch 10 and contact block 8 additional in the lock 3, microswitch 10 is fixed on the lock housing 15, contact block 8 is connected on day pike pole plate 7, when the same day, pike pole plate 7 was in top dead-centre, contact block 8 makes a pair of normal opened contact closure of switch 10, asks for an interview Fig. 3.

Couple of conductor 2 links to each other the AB point at tongue tube 6 two ends on a pair of normal opened contact of switch 10 and the switch enclosure 1 respectively, forms circuit as shown in Figure 2.

The duty of existing product magnetic switch is such:

When system was on the alert, when just entry door was closed, this moment, magnetic box was close to switch enclosure, and tongue tube is in the magnetic field, is conducting between its ends A B.

When system is in alarm condition, when just opening the door, because of magnetic box away from, tongue tube leaves magnetic field, B is separated for its ends A, switch enclosure emission this moment wireless signal, alarm host machine has received signal, starts to report to the police.

The utility model is abandoned magnetic box, tongue tube 6 these roads have disconnected like this, and another bypass---microswitch circuit in parallel, so exciting switch has just played the effect of gauge tap box 1, when a pair of normal opened contact that is inserted on the switch 10 is closed, conducting between AB, switch enclosure 1 is on the alert.When this disconnected normal opened contact, this moment, AB was separated, and switch enclosure 1 is in alarm condition.

When owner goes out to lock a door, with key with lock core mandrel two circles that reversed.Lock 3 this moment and inner make through a series of transmissions that main dead bolt 13 is outer to reach maximum value (15-20mm), a day pike pole plate 7 also has been raised to top dead-centre, and ground pike pole plate also reaches bottom dead centre down.Contact block 8 pressings this moment microswitch 10, make its normal opened contact closure.At this moment switch enclosure 1 is in " warning " state.

When the invador unblanks, when he just the mandrel of rotational lock core because a day pike pole plate 7 moves downward, make contact block 8 leave microswitch 10 less than 1 circle, " shoulder pole " of switch 10 lifts, the AB point-to-point transmission disconnects.This moment, the antenna emission wireless signal of switch enclosure 1 was given alarm controller, had started warning immediately.At this moment, main dead bolt 13 have at least extension elongation half (7.5-10mm) still in the keyhole of doorframe, day bar, the keeper of rod end head also have half too at least extension elongation also in the keyhole of doorframe, and little dead bolt 14, also door is still being fastened in not action as yet with a bolt or latch.

When just reporting to the police, the invador still is blocked in outdoors, has realized " in-advance " warning, has improved the warning effect, has improved antitheft anti-theft feature.

And owner can use remote controller earlier when opening the door, and warning system " is withdrawn a garrison ", then can not start warning.

The utility model has following advantage:

1, realizes " in-advance " warning, improved the warning effect, improved anti-theft capability.

2, simple in structure, the reliability height.

3, easy construction, cost is low, and cost performance is good.Because only increase a P cock and several finding in the lock, the repacking of magnetic switch is also very simple.

4, do not influence the original function of lock.

5, owing in the warning system, alarm controller is arranged, therefore be suitable for carrying out omnibearingly comprehensively setting up defences, safety is good.

The specific embodiment:

The utility model is made up of switch enclosure 1 and core-inset type theftproof lock 3 two parts of magnetic switch, and is middle with lead 2 connections.

Opening outside the wainscot of door leaf that box 1 is contained in entry door of magnetic switch asked for an interview accompanying drawing 1, formerly abandons with switch enclosure 1 matching used magnetic box.

Core-inset type theftproof lock 3 is to form with the common core-inset type theftproof lock transformation of the way.That changes a social system to the effect that installs a microswitch 10 and contact block 8 additional in lock.

As shown in Figure 2, characteristics of the present utility model are to come gauge tap box 1 with microswitch 10.Are the keys that influence the warning quality triggering opportunitys of switch 10.Contact block 8 is installed on which interior part of lock, and multiple scheme is arranged, but as shown in Figure 3, is installed on day pike pole plate 7 to best.

It is the reasons are as follows:

1, can realize that appropriateness sets up defences, make things convenient for use.

There is man-hour generally to need not to set up defences when indoor.The Push And Release of door has only little dead bolt 14 that action is arranged in the door lock 3 at this moment, and day pike pole 7 and attonity.Therefore also attonity of switch 10.At this moment, be not set up defences.This is that people expect, in order that convenient.

When indoor nobody the time generally need set up defences.At this moment, owner has just implemented to set up defences with key counter-rotating two circle lock cores, and this also is that people expect, in order that safety.This has just realized that appropriateness sets up defences.

2, can realize reporting to the police as early as possible, the warning quality is good.

It pike pole plate 7 is one of parts in the lock that moves the earliest when unblanking and forcing open the door, and it goes up contact block 8 dresses and can realize warning as early as possible, and before Men Wei opened, reporting to the police as early as possible, this also was that people expect.

That 3, takes precautions against is wide, helps safety.

As above bar is stated, and has promptly prevented unblanking to enter the room, and anti-again forcing open the door entered the room good anti-theft effect.

Contact block 8 is another keys that influence the warning quality with the relative positional accuracy of switch 10.

The error that contact block 8 and switch 10 relative positions are bigger may cause reporting to the police and lag behind, and also may cause switch 10 effectively not triggered and the failure of reporting to the police.

For overcoming the above problems, the position design one-tenth of contact block 8 can be finely tuned.During installation, can realize relative position between switch 10 and the contact block 8 accurately, thereby accurately report to the police.

Switch 10 is as follows with the concrete configuration scheme of contact block 8 in lock 3:

Microswitch 10 is firm on lock housing 15 regularly with two groups of screws 11 and nut 12.

Contact block 8 is fastened on day pike pole plate 7 with screw 9, and the elongated slot in the middle of the contact block 8 designs for realizing being convenient to finely tune about its position.

Connect on the switch 10 lead 2 of 2 of AB in a pair of normal opened contact and switch enclosure 1, two ends should weld, and answer secure fixation for one section in the middle lock, in case the interior moving parts of lock is with its scratch.
