Abstract
The utility model discloses a suspended ball type vandal-proof alarming device, which comprises sensors arranged in a door/window guardrail, an alarm, a power supply for providing electric power for the alarm, and a power switch, wherein each sensor consists of a metal ball suspended in a hollow guardrail of the door/window guardrail through a suspension wire and a key positioned at the bottom of the hollow guardrail; and the keys, the power supply and the power switch form a sensor loop. The suspended ball type vandal-proof alarming device is characterized in that an electromagnetic coil is arranged on the sensor loop; a bracket is arranged beside the electromagnetic coil, a sensing ball is arranged at the top of the bracket; and the bottom of the bracket is connected with a key switch of an alarming closed loop with an alarming function. The suspended ball type vandal-proof alarming device has a vandal-proof function, and the function of transmitting an alarming signal even under the condition that the door/window guardrail is cut off is ensured.
Description
Technical field
The utility model relates to a kind of burglar alarm, particularly relates to a kind of belpharoedema formula damage preventing alarm device.
Background technology
At present, in some remote dwelling houses, shop the adverse events of burglary takes place through regular meeting, in order to prevent theft; People have designed the Anti-theft door and window with anti-theft feature, such as application number are to disclose a kind of guard-rail for window shearing-proof warning device in 200720095291.2 the Chinese patent, but in long-term practice process, find; There is following defective in this burglar alarm: when the lawless person cuts off suspension line; Alarm can send alerting signal, at this moment, and after the lawless person hears alerting signal; Can cut off the bottom transverse guardrail of guard-rail for window at once; Thereby alarm circuit is cut off, so the alerting signal termination, can not play good warning effect.
Summary of the invention
The technical matters that the utility model will solve is: existing door window antitheft warning device is improved, a kind of belpharoedema formula damage preventing alarm device with tamper-proof function is provided.
The technical scheme that the utility model is taked for the technical matters that exists in the solution known technology is:
A kind of belpharoedema formula damage preventing alarm device comprises: be installed on sensor in the guard-rail for window, alarm, the power supply and the power switch of electric energy are provided for alarm; Said sensor is hung in the inner metal ball of the hollow guardrail of guard-rail for window with suspension line by one and is formed said telegraph key, said power supply and sensor loop of said power switch composition with the telegraph key that is positioned at hollow guardrail bottom; It is characterized in that: on said sensor loop, be provided with solenoid; Be provided with a support on the next door of said solenoid; Be equipped with an induction sphere at the top of said support, the key switch that the bottom of said support and has the warning closed-loop path of warning function is connected.
As preferred version, the utility model has also adopted following technical measures:
Said warning closed-loop path is composed in series by power supply, alarm, key switch.
Said sensor loop is provided with protective resistance.
Said warning closed-loop path is provided with protective resistance.
Said alarm is an audible-visual annunciator.
Advantage and the good effect that the utlity model has are: through the warning device that adopts sensor loop and warning closed-loop path to combine; Avoided the situation that alarm lost efficacy under the situation that door and window bottom horizontal bar cut off to take place; Guarantee the operate as normal of alarm, had good tamper-proof function.

.:1, hollow guardrail among the figure; 2, suspension line; 3, metal ball; 4, telegraph key; 5, induction sphere; 6, sensor loop; 7, warning closed-loop path; 8, alarm.
Embodiment
For further understanding summary of the invention, characteristics and the effect of the utility model, the following examples of giving an example now, and conjunction with figs. specifies as follows:
See also Fig. 1, a kind of belpharoedema formula damage preventing alarm device comprises: sensor, sensor loop 6 and warning closed-loop path 7; Said sensor is hung in the hollow guardrail of guard-rail for window 1 inner metal ball 3 with suspension line 2 by one and is formed with the telegraph key 4 that is positioned at hollow guardrail 1 bottom, and said sensor loop is composed in series by said telegraph key 4, solenoid, said power supply and said power switch; Said warning closed-loop path is composed in series by power supply, alarm 8, key switch, on the key switch of said warning closed-loop path, is provided with a support, puts an induction sphere 5 at the top of said support.In order to prevent short circuit, said sensor loop 6 is provided with protective resistance, and said warning closed-loop path 7 is provided with protective resistance; Wherein, said alarm 8 is an audible-visual annunciator.
The principle of work of this specific embodiment is: after the suspension line in the hollow guardrail 12 is cut off; After dropping, metal ball 3 connects telegraph key 4; Telegraph key 4 is connected sensor loop 6, and under the acting force of solenoid, induction sphere 5 drops from support; Connect warning closed-loop path 7, alarm 8 starts the function that realizes warning.
More than the embodiment of the utility model is specified, but said content is merely the preferred embodiment of the utility model, can not be considered to be used to limit the practical range of the utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the utility model.
