Description

Multiple entry lock regulation burglar alarm

The utility model belongs to the lock regulation burglar alarm, particularly about multiple entry lock regulation burglar alarm.

At present, the inlet formula burglar alarm kind that is applicable to occasions such as family, office is a lot, but most function singleness, the rate of false alarm height, disguised poor, be easy to destroyed, influence it and promote the use of, simultaneously, multi-user's formula alarm generally adopts central control unit and utility power, though function is more powerful, as go to pot or self fault makes the total system paralysis easily.

The utility model purpose is that rate of false alarm is low for occasions such as family, office provide powerful, is convenient to install and use, and is difficult for ruined multiple entry lock regulation burglar alarm.

The utility model is realized by following measure: it comprises two flapper locks, inlet detector, locking-controller, control circuit, circuit for alarming and power supply.Its special character is: locking-controller is installed in the keeper of two flapper locks, the inlet detector that is installed in door and window constitutes with general action type detector by destroying the action type detector, destroy the action type detector and on common Switch for door and window, install destruction qualification sheet composition additional, when door and window was pushed open by force, Switch for door and window itself limited sheet with destruction and contacts.Locking-controller comprises two contact switch K ₀₁, K ₀₂And K ₁, K ₂, K ₂All disconnect when door is locked, door is opened then K ₁Closure, door is pushed open then K by force ₂Closure is by the contact switch K of rubber wheel control ₀₁, closure when door is locked, otherwise disconnect.

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is a destruction action type detector swing-in structural drawing of the present utility model.

Fig. 2 is the outward opening structural drawing of destruction action type detector of the present utility model.

Fig. 3 is a main-inlet locking-controller circuit diagram of the present utility model.

Fig. 4 is single user's of the present utility model circuit theory diagrams.

Referring to Fig. 1, Fig. 2,1---destroy and limit sheet, 2---little wood screw stator of flexible pad, detector is an electromechanical, promptly utilizes the door and window mechanical motion to produce the electric weight switching signal, it divides two kinds: destroy action type and general action type.Destroying action type is that invasion destroys the detector that the Switch for door and window device just moves when taking place by force, it is to install to destroy on Switch for door and window or Bolt for door/window to limit sheet, during normal condition, 1,2 " disconnections ", when illegal invasion takes place, 1,2 contacts, i.e. " closure " produces alerting signal and is sent to control circuit.General action type detector is small-sized microswitch, and when door and window moved, alerting signal just took place detector.

Referring to Fig. 3, K ₁---the general action type detector of main-inlet, K ₂--main-inlet destroys action type detector, K ₀₁, K ₀₂---lock-controlled switch, locking-controller and double cylinder rim drawback lock are used in main-inlet, and locking-controller is installed in the keeper of two flapper locks, and its effect is to remove when using the key normal door to report to the police, and when door was locked, alarm entered pre-alarm state.Locking-controller is by K ₁, K ₂, K ₀₁, K ₀₂Form.Lock-controlled switch is the rotary single-pole double-throw switch (SPDT) of a band rubber wheel, and when locking, Square lock bolt drives the normally open contact K that rubber wheel rotates to switch ₀₁" closure ", system enters pre-alarm state, when turning the key in the lock, rotary switch normally open contact K ₀₁" disconnection " removed and reported to the police.Main-inlet destroys action type detector K ₂In locking-controller contact doorframe one side, when the keeper normal mounting, K ₂Elastic body be stressed K ₂" disconnection ", and loosening or come off K when keeper ₂" closure " reports to the police to control circuit.General action type detector K ₁The inside in the bullet tongue hole of locking-controller, when door is shut, the top of the oblique tongue of lock collision K ₁Elastic body, K ₁" disconnection ", when opening the door, tiltedly tongue leaves K ₁, K ₁" closure ".During with the key normal door, square tongue moves earlier and makes K ₀₁" disconnection " removed and reported to the police, and at this moment opens door, K ₁" closure " but do not report to the police, but open the door unusually when taking place, square tongue is moving or do not move to position, K should be arranged ₀₁Still " closure ", open the door this moment is K ₁" closure " can send alerting signal.

Referring to Fig. 4, K ₀₁, K ₀₂---lock-controlled switch, K _A1---hand switch, K _A2---reset switch, K ₁₀, K ₁₁K _1N---general action type detector, K ₂₀, K ₂₁K _2N---destroy the action type detector, J, J ₁---relay, BG ₁, BG ₂---PNP pipe, 3DG ₁₂, 8050---NPN pipe, R ₄---0.25W loudspeaker, R ₅---2W loudspeaker, IC ₉₅₆₁---music-integrating block.Control circuit is by J, J ₁, resistance R ₁, two PNP pipe (BG ₁, BG ₂), K _A1, K _A2Form.When detector elicites robber's feelings, produce alerting signal, the control warning horn sends lasting alerting signal; Whether when the user goes out to lock the main-inlet door lock, checking has other door and window not shut, promptly not to be in pre-alarm state, if any, send cue.The control circuit principle of work is: destroyed when some entrance door window, and make some destroy action type detector " closure ", relay J gets electronic work and self-locking, and high-power (2W) warning horn continues to report to the police; When door is K by lock ₀₁When " closure ", as this moment all other door and windows all shut i.e. K ₁₀, K ₁₁K _1NDeng all " disconnection " relay J, J ₁All be failure to actuate, alarm free, system is in pre-alarm state, if feelings, i.e. K take place to steal this moment ₁₀, K ₁₁K _1NOne " closure " arranged, and then J gets electronic work, and alerting signal is through music IC ₉₅₆₁Amplify R with triode 8050 ₅The loudspeaker sounding alarm, and make to report to the police by the normally opened contact self-locking of J and continue; When if door is locked, K ₁₀, K ₁₁K _1NSome " closure " (having door and window not shut) is because normally closed contact K ₀₂" disconnection " earlier, and K ₀₁Back " closure ", BG at this moment ₁, BG ₂Conducting, J ₁Get electronic work, alerting signal is through music IC ₉₅₆₁With triode 3DG ₁₂Amplify, the 0.25W loudspeaker sends cue, at this moment J ₁Normally closed contact " disconnection " stop J action, J ₁No auto-lock function is if open door with key again, K this moment ₀₂" closure ", BG ₁, BG ₂End J ₁Restore, cue finishes, and the user just can shut door and window again, locks making warning be in pre-alarm state again.If the user is at indoor invasion or other abnormal conditions by force, the available hand switch K of running into _A1Report to the police also available reset switch K _A2Stop reporting to the police.Circuit for alarming adopts two kinds of power warning horns of size, by resistance R ₂, R ₃, music IC ₉₅₆₁Two, loudspeaker R ₄, R ₅, two compositions of triode NPN.Circuit for alarming is accepted the alerting signal that control circuit is sent here, through IC ₉₅₆₁Amplify the loudspeaker sounding alarm with diode NPN.High-power (2W) warning horn is used for stolen warning, and miniwatt (0.25W) warning horn is used for prompting and reports to the police.

This burglar alarm has following advantage: good anti-theft effect, and system is simple, Rate of false alarm is low. Cost is low, and power consumption is little, and disguised strong, function is big, the user Just. This system also can carry out valuables and report to the police, important case, cabinet burglar alarm, And be easy to link with other burglary-resisting system.
