Abstract

The utility model discloses an anti-theft alarm protecting the surface of a case, which is installed in a surface of the case; namely, two conductive members (3) and an insulating layer (4) are arranged between the inner layer (1) and the outer layer (2) of the case; one end of the two conductive members is respectively connected with a circuit switch generating the alarm sound. When the theft thrusts the alarm surface of the case no matter by any sharp object, the alarm circuit sends out the alarm whistle sound right away, so the anti-theft alarm protecting the surface of the case increases the safe feeling for the people. The utility model has the advantages of simple device and low cost; the anti-theft alarm protecting the surface of the case can be installed on any surface of the case without influencing the production process of the original case.

Description

Anti-theft alarm protecting surface of case

The utility model belongs to antitheft the alarm of a kind of case and bag that often uses in the daily life.

Society goes up and bag is punctured with sharp device through the robber person that often sees at present, steals article in the bag, brings very big economic loss to people.Present various burglar alarm is a lot, and as wallet burglar alarm, suitcase burglar alarm etc., they all exist the structure more complicated, and required electronic component is many, usually influences the production technology of former case and bag during installation.

The purpose of this utility model is to avoid above-described weak point in the prior art and provides a kind of case and bag antitheft alarm.

The utility model reaches by following approach:

In a face of each case and bag, two electric-conductors and insulating barrier promptly are housed between Bao internal layer cloth and the outer cloth, insulating barrier is to be clipped between the electric-conductor, and each end of contactor and two electric-conductors that produces alarm sound is linked to each other.

Fig. 1 is the front view of the utility model case and bag face;

Fig. 2 is the A-A cutaway view of the utility model case and bag face;

Fig. 3 is an electrical schematic diagram of the present utility model.

The utility model will be further described in conjunction with the accompanying drawings:

This device mainly is made up of case and bag skin (1), internal layer (2), two electric-conductors (3), insulating barrier (4), binding line (5), electric-conductor (3) is selected the tin platinum paper material for use, cost is low, contact-making surface is big, and it is installed between the ectonexine cloth of bag, and is fixing with binding line (5), in the binding process, the binding hole may appear in tin platinum paper changes the limit, adopts insulating barrier that two tin platinum papers are separated, and can guarantee the reliability of reporting to the police.The circuit (6) that produces alarm sound is connected on two tin platinum paper lower ends respectively, does pigtail splice with staple or other material and forms " face switch ", links to each other with the warning circuit K switch.The alarm sound circuit is contained in any space of case and bag.

Circuit theory diagrams (6), circuit is by an IC ₁(HL483), loudspeaker Y, power supply E, K switch form, after the case and bag face was punctured by sharp device, two tin platinum papers linked to each other, power switch K is approaching, integrated circuit HL483 starts working, and sends police whistle sound.

This device can be installed on the case and bag arbitrary face, adopts parallel form that the joint on every the tin platinum paper is communicated with the circuit of same alarm sound.

The utility model major advantage: 1, this apparatus structure is simple, and cost is low, this device can be installed on the arbitrary face of case and bag, does not affect the production technology of former case and bag; 2, when no matter robber person punctured case and bag warning face with which kind of sharp instrument, warning circuit sent police whistle sound immediately, strengthened people's the sense of security; 3, not power consumption during circuit static.

Claims

1, antitheft alarm of a kind of case and bag, it comprises case and bag skin (1), internal layer (2), it is characterized in that between the internal layer of case and bag and outer cloth, two electric-conductors and an insulator being housed, insulator is to be clipped between the electric-conductor, the contactor that produces alarm sound links to each other with each end of two electric-conductors, and the alarm sound circuit is to be contained in any space of case and bag.

2,, it is characterized in that electric-conductor selects the tin platinum paper material for use according to antitheft alarm of the described case and bag of claim 1.

3, according to antitheft alarm of the described case and bag of claim 1, it is characterized in that this device can be installed on the case and bag arbitrary face, adopt parallel form that the circuit of joint on every the tin platinum paper and same alarm sound is joined.
