Description
The utility model triggering type anti-theft alarming device is a kind of device of burglar alarm in financial quarters and each enterprises and institutions and the people's daily life.
The present alarm that uses, sensitivity is not high, and out-of-control phenomenon is arranged, and the cost height.
The purpose of this utility model is to make a kind of triggering type anti-theft alarming device, and highly sensitive, anti-corrosive properties are strong, but the effective good reliability of special messenger is simple in structure, is easy to make.
The utility model mainly by combination lock trigger switch (1), built-in lock trigger switch (4), shock-activated switch (7), drawer-lock master switch (10), warning circuit (13), relay (14), ground connection constant open contact (15), connect negative pole constant open contact (16) etc. and form.
The utility model most preferred embodiment as shown in the figure, mainly by combination lock trigger switch (1), built-in lock trigger switch (4), shock-activated switch (7), drawer-lock master switch (10), warning circuit (13), relay (14), ground connection constant open contact (15), connect negative pole constant open contact (16) etc. and form.Combination lock trigger switch (1) is made up of combination lock (2) and combination lock elastic sheet metal (3), and combination lock elastic sheet metal (3) and combination lock (2) insulate and fix.Combination lock (2) is fixed on the iron gate plate (19), and combination lock elastic sheet metal (3) insulate mutually with iron gate plate (19), but is fixed on the iron gate plate (19).Distance was that the screw on the plate of garden can be run into combination lock elastic sheet metal (3) when rotating combination lock (2) just when combination lock elastic sheet metal (3) was installed with combination lock (2).Built-in lock trigger switch (4) is made up of built-in lock (5) and built-in lock elastic sheet metal (6), built-in lock elastic sheet metal (6) and built-in lock (5) insulate and fix, built-in lock (5) is fixed on the iron gate plate (19), when built-in lock (5) is in by off status, between dead bolt root and the built-in lock elastic sheet metal (6) less gap is arranged, when thereby the key of built-in lock (5) rotated built-in lock (5) a little, the dead bolt root will be run into built-in lock elastic sheet metal (6).Shock-activated switch (7) is made up of latten(-tin) (8) and elasticity garden post hammer (9), and elasticity garden post hammer (9) is connected with a little spring, and little spring passes the center, hole, garden of latten(-tin) (8).Latten(-tin) (8) is fixed on the lock frame iron plate, and when being subjected to less external force, vibration elastic takes place spring garden post hammer (9), will run into latten(-tin) (8).Drawer-lock master switch (10), form by drawer-lock (11) and drawer-lock elastic sheet metal (12), drawer-lock (11) is fixed on the iron gate plate (19), drawer-lock elastic sheet metal (12) insulation is fixed on the iron gate plate (19), when drawer-lock (11) was in by off status, drawer-lock (11) lock house withstood drawer-lock elastic sheet metal (12).Warning circuit (13) and relay (14) coexist on the circuit board, with screw circuit board is fixed on the iron gate plate (19), loudspeaker (17) are fixed on the iron gate plate (19), loudspeaker (17) voice coil loudspeaker voice coil circuit is connected between power supply (18) positive pole and warning circuit (13) output, and 2. relay (14) coil holds same warning circuit (13) () end with on the drawer-lock elastic sheet metal (12) that is connected in the drawer-lock master switch (10).1. relay (14) coil held and warning circuit (13) (+) end with connecing on power supply (18) positive pole, combination lock elastic sheet metal (3) and built-in lock elastic sheet metal (6) and latten(-tin) (8), relay (14) connect negative pole constant open contact (16) same connect on power supply (18) negative pole whole circuit.
Warning circuit (13) is in parallel with relay (14) circuit, combination lock trigger switch (1), built-in lock trigger switch (4), shock-activated switch (7), be that ground connection constant open contact (15) with relay (14) connects negative pole constant open contact (16) mutually and connect respectively, series connection drawer-lock master switch (10) between two parallelled circuits, so latter two parallel circuit is connected on respectively on power supply (18) both positive and negative polarity.
It is such using and moving; With the drawer-lock key drawer-lock (11) is forwarded to the end in the counterclockwise direction, then master switch is connected, can possess warning function, at this moment no current still in the circuit, when rotating combination lock (2), when as long as the screw on the plate of garden at a touch electrically isolates from its combination lock elastic sheet metal (3) or opens built-in lock (5), as long as dead bolt is built-in lock elastic sheet metal (6) at a touch, and twist iron gate plate (19) or touch iron gate plate (19) gently, a little during the oblique body, as long as spring garden post hammer (9) is run into latten(-tin) (8), warning circuit (3) relay (14) ground connection constant open contact (15) contacts, will send warning by loudspeaker (17), with the drawer-lock key drawer-lock (11) is rotated in a clockwise direction and stop on earth reporting to the police.
The utility model triggering type anti-theft alarming device, simple in structure, be easy to make, be applicable to the safety cabinet that constituent parts uses, and the door of family expenses, the warning sensitivity high reliability is strong.
