Detailed Description

In order to make the technical means, the creation features, the achievement purposes and the functions of the present invention easy to understand and understand, the present invention is further explained by combining the following specific drawings.

Examples

As shown in fig. 1 to 4, an anti-theft lithium battery case includes an upper case 1 and a lower case 2, lithium cell,

burglar alarm

3, 1 top of last casing is equipped with anodal wiring hole 101 and negative pole wiring hole 102, anodal wiring hole 101 and negative pole wiring hole 102 are connected with the positive negative pole of lithium cell respectively, it forms the battery case of built-in lithium cell with casing 2 equipment together to go up

casing

1, 3 electric connection of burglar alarm has trigger switch 301, burglar alarm 3 establishes inside the battery case, 3 electric connection of burglar alarm has four

trigger switch

301, 2 bottom four corners of casing are equipped with four supporting legs 201 down, be equipped with the line hole in the supporting legs 201, every supporting legs 201 bottom is equipped with a trigger switch 301, trigger switch 301 passes through the inside line hole of supporting

legs

201 and 3 electric connection of burglar alarm, burglar alarm 3 passes through the lithium cell power supply in the battery case.

The bottom of the lower shell 2 is provided with a groove 202 for placing the burglar alarm 3, and the burglar alarm 3 is placed into the groove 202 from the inside. The joint of the upper shell 1 and the lower shell 2 is fixedly connected by arranging a buckle 103 and a clamping groove 203. The top of the upper shell 1 is provided with a handle 104.

Fig. 5 is a schematic diagram showing a typical circuit configuration of the burglar alarm 3. In the circuit, the SCR, the R1 and the trigger switch 301(AN) form a silicon controlled trigger switch circuit; IC1, R2, VT1, VT2 and BL form an analog siren sound circuit. In the initial state, the trigger switch 301(AN) is pressed by the lithium battery, so that the two normally closed contacts are disconnected, the SCR is blocked without a trigger signal, and the alarm does not work. When the lithium battery is lifted, the AN two contacts are automatically closed, the trigger end of the SCR obtains a trigger signal from the positive electrode of the power supply through R1, the SCR is conducted, the IC1 is electrified to work, and the siren sound electric signal output by the output end of the SCR is amplified through VT1 and VT2 power, so that the loudspeaker is pushed to give a bright alarm sound. At this time, even if the lithium battery is put back or the AN is broken, the alarm sound cannot be prevented. The alarm can be released only by turning on the remote switch S.
