Description
The utility model is a kind of switching regulator burglar alarm, is applicable to be installed on various doors, the window, makes burglar alarm.
Existing switching regulator burglar alarm, the auto-lock function of not reporting to the police is installed on door, the window, when door, when window is unlocked, alarm equipment alarm, when door, window were closed again, alarm also cut out, and can not play the warning effect effectively.
The utility model is a kind of switching regulator burglar alarm with warning auto-lock function, is installed on door, the window, when door, when window is unlocked, alarm equipment alarm, when door, window were closed again, alarm was still reported to the police, until closing alarm with key, it can play the burglar alarm effect effectively.
The purpose of this utility model is achieved in that with an electric switch and a relay forms the relay self-locking circuit self-locking device of promptly reporting to the police, and the electric switch of a band mechanical lock is made the alarm master switch, and the electric bell news of doing to report to the police are rung device.When electric switch is pressed, the electric contact conversion, the relay self-locking is also connected the electric bell power supply, closes the alarm general supply until the electric switch of band mechanical lock.
Fig. 1 is circuit theory diagrams of the present utility model.
Below in conjunction with Fig. 1 the utility model is described in further detail.
With reference to Fig. 1, the power switch 1 of band mechanical lock, electric switch 2, relay 3, the normally opened contact 3-1 of relay 3, electric bell 4, pilot lamp 5.Principal character of the present utility model is that the electric switch 2 and the normally opened contact 3-1 of relay 3 are connected in parallel, the coil of relay 3 and electric bell 4 are connected in parallel, and electric switch 2, the normally opened contact 3-1 of relay 3 and the coil of relay 3, electric bell 4, the power switch 1 composition electric power loop that is connected in series of band mechanical lock.The end and the power supply phase line that are about to power switch 1 are joined, hold a end in addition with electric switch 2, the moving contact of normally opened contact 3-1 joins, the end in addition of electric switch 2, coil one end of the fixed contact of normally opened contact 3-1 and relay 3, one end of electric bell 4 joins, and the coil of relay 3 is end in addition, and the end in addition of electric bell 4 joins with zero-power line.When electric switch 2 is in normally open (be equivalent to door, window is closed, electric switch is pressed), power switch 1 is in normally off (be equivalent to turn on the power switch connect the alarm power supply with key), and pilot lamp 5 is bright, and alarm is on the alert.When electric switch 2 be in normally off (be equivalent to door, window is unlocked, electric switch is unclamped), relay 3, normally opened contact 3-1 converts normally closed contact (be equivalent to relay self-locking promptly report to the police self-locking) to, electric bell 4 gets electric ringing, and is in normally open (being equivalent to key powered-down switch breaking alarm power supply) until power switch 1.
