Description

橱柜防盗报警器 cabinet burglar alarm

技术领域technical field

本实用新型涉及防盗报警领域的一种橱柜防盗报警器The utility model relates to a cabinet anti-theft alarm in the field of anti-theft alarm

背景技术Background technique

目前的家庭或办公室的橱柜被撬多发生在夜间，而大多没有任何防盗性能。特殊情况下，重要的橱柜(如保险柜)也是采用机械防盗结构，自身缺少报警功能。Most of the cabinets in current families or offices are pried at night, and most of them do not have any anti-theft performance. In special cases, important cabinets (such as safes) also adopt mechanical anti-theft structures, which themselves lack alarm functions.

发明内容Contents of the invention

本实用新型的目的就是针对现有技术存在的缺陷，提供一种简单可靠的橱柜防盗报警器。The purpose of the utility model is to provide a simple and reliable anti-theft alarm for cabinets aiming at the defects in the prior art.

其技术方案是：光敏电阻R1连接可调电阻W和三极管T·组成光控开关电路并连接到报警集成电路IC，报警集成电路IC连接电阻R2和喇叭L组成报警电路，电源连接开关K后连接到光控开关电路和报警电路。所述的开关(K)为触动开关。The technical solution is: the photosensitive resistor R1 is connected with the adjustable resistor W and the triode T to form a light control switch circuit and connected to the alarm integrated circuit IC, the alarm integrated circuit IC is connected to the resistor R2 and the horn L to form an alarm circuit, and the power supply is connected to the switch K and then connected to the alarm circuit. To the light control switch circuit and alarm circuit. The switch (K) is a touch switch.

本实用新型具有结构简单、加装方便，安装在需要的家庭或办公室的橱柜门或抽屉上，可起到防盗、报警的目的，如果与远程报警网络连接配套使用，效果更好。The utility model has the advantages of simple structure and convenient installation. It can be installed on the cabinet door or drawer of the desired family or office, and can serve the purpose of anti-theft and alarm. If it is used in conjunction with a remote alarm network connection, the effect will be better.

附图说明Description of drawings

附图是一种实施例的电路原理图。Accompanying drawing is the circuit schematic diagram of a kind of embodiment.

具体实施方式Detailed ways

下面结合附图就其电路构成和工作原理作进一步描述：The following is a further description of its circuit composition and working principle in conjunction with the accompanying drawings:

图中K是电源触动开关，随橱柜的打开而接通，随橱柜的关闭而断开；DC是电源；光敏电阻R1连接可调电阻W和三极管T组成光控开关电路；报警集成电路IC(LC179)连接电阻R2和喇叭L组成报警电路。白天主人打开橱柜时，虽然K接通，但由于光敏电阻R1受光照而呈现低阻抗，三极管T截至，报警集成电路IC得不到电源而不工作，喇叭L不发声。晚上如有盗贼打开橱柜时，K接通，此时光敏电阻R1无光照而呈现高阻抗，三极管T导通，因此报警集成电路IC得到电源而工作，喇叭L发出报警，起到防盗报警作用。K in the figure is a power touch switch, which is connected with the opening of the cabinet and disconnected with the closing of the cabinet; DC is the power supply; the photosensitive resistor R1 is connected with the adjustable resistor W and the triode T to form a light control switch circuit; the alarm integrated circuit IC ( LC179) connect resistor R2 and horn L to form an alarm circuit. When the owner opens the cabinet during the day, although K is connected, the photoresistor R1 is exposed to light and presents low impedance, the transistor T is cut off, the alarm integrated circuit IC cannot get power and does not work, and the speaker L does not sound. If a thief opens the cabinet at night, K is connected. At this time, the photoresistor R1 has no light and presents high impedance, and the transistor T is turned on. Therefore, the alarm integrated circuit IC receives power and works, and the speaker L sends out an alarm, which plays the role of anti-theft alarm.
