Description

Pocket theftproof alarm

The utility model relates to a kind of alarm, particularly a kind of burglar alarm that is installed on the carry-on pocket.

People get used to depositing money and goods in the clothing pocket and are easy to carry; but the thief in the society always wants to take off away the money and goods in people's pocket by fair means or foul; the money and goods of carrying to the citizen causes danger, is protection citizen's property safety, and people have developed various types of burglar alarms.To remind the wearer to note the money and goods in the pocket and to arrest the robber.Be 89212468.7 1 kinds as the disclosed application number of Chinese patent and have anti-clothing (trousers) the pocket inner bag of stealing function, it is formed inner bag by installing warning circuit on the cloth bag and is sleeved in clothing (trousers) pocket, when the thief unties with hand or severs clothing (trousers) the pocket inner bag of dress with knife, send audible alarm, but this alarm complex structure, owing to adopt inner bag to make what the pocket drum roused, very inconvenient, reporting to the police, it is also unreasonable to start, cut off with lead and to be used as the enabling signal of reporting to the police, obviously unreasonable, plain conductor is to cut constantly sometimes.

The carry-on pocket burglar alarm that provides a kind of molecule that avoids theft that people's clothing pocket is stolen and severed is provided the purpose of this utility model.

The utility model is finished with following mode: the pocket burglar alarm is by the alarm switch K serial connection power switch K that is contained on the pocket with oneself ₁, power supply E, sound equipment integrated oscillator IC promote acoustical generator D and constitute.Alarm switch K is by anti-cutting alarm switch K ₂Anti-theft alarm K switch in parallel ₃Constitute anti-cutting alarm switch K ₂Be contained on the liner plate in the pocket, be pressed in by shell fragment and constitute K switch on the stationary contact ₂Two electric contacts, the insulation inserted sheet inserts between shell fragment and the stationary contact, the insulation inserted sheet is articulated in the upper end of liner plate through extension spring, the other end is articulated in the lower end of liner plate, anti-theft alarm K switch through backguy ₃The mouth that is contained in pocket inserts the K switch that two shell fragments constitute along last by blind plug ₃Between two electric contacts.Anti-cutting alarm switch K ₂One or more are arranged, the anti-theft alarm K switch ₃One or more are arranged, and liner plate is an insulcrete, vertical or horizontal or oblique being contained in the pocket.

That the utility model alarm has is simple in structure, volume is little, in light weight, cost is low is suitable for being installed in the pocket of people's clothing, dependable performance, have and turn off power switch when oneself taking money and goods and do not report to the police, automatically reporting to the police when the thief steals, is that people are away from home and prevent to steal the desirable articles for use of molecule.

Below in conjunction with accompanying drawing the utility model is described in further detail:

In Fig. 1, the utility model alarm is that electric elements and switch are installed on the clothing pocket (4), installing power switch K on a jiao of pocket (4) ₁, acoustical generator D, button cell E, sound equipment integrated oscillator IC, oscillator IC can adopt existing general musical film or the ad hoc integrated package that the warning speech is arranged: the anti-cutting K switch ₂Be installed on the liner plate (2) K switch ₂Be to constitute its two electric contact by stationary contact (8) and moving contact (7), moving contact (7) is a shell fragment, as shown in Figure 2, has an insulation inserted sheet (5) to insert switch k ₂Two electric contacts (8) (7) between, one end of insulation inserted sheet (5) is articulated in the upper end of liner plate (2) through extension spring (1), the other end is articulated in the lower end of liner plate (2) through backguy (3), and insulation inserted sheet (5) can be stablized and keeps being inserted in K switch under the effect of backguy (3) ₂Two electricity connect between, make K switch ₂Open, and extension spring this moment (1) tension is and flexible, backguy (3) adopts cotton or chemical fibre to make, and when backguy (3) is cut off, the inserted sheet that insulate so (5) will be drawn out K switch under the elastic pulling force effect of extension spring (1) ₂Two electric contacts between, make K switch ₂Closed.Anti-pushing aside closed K ₃As shown in Figure 3, it is shell fragment (9) the formation K switch by two contacts ₃Two electric contacts, have a blind plug (6) to be inserted in K switch ₃Two electric contacts between, make K switch ₃Open, when pulling out blind plug (6), two shell fragments contact again, make K switch ₃Connect.The anti-cutting K switch ₂Be contained on the liner (2), liner (2) but the vertical or horizontal or oblique installation of bead bag (4), mounting means with the clothing pocket is determined, liner plate (2) is that insulating material is made, it is after severing pocket that liner plate (2) also has an effect, and liner plate (2) can block the unlikely pocket that drops out very soon of money and goods.Anti-pushing aside closed K ₃Be installed in the opening edge edge of pocket (4), can make button and use.Circuit of the present utility model connects as shown in Figure 4, and anti-pushing aside closed K ₃With the anti-cutting K switch ₂Parallel connection, back serial connection power switch K in parallel ₁With battery E, integrated oscillator promotes zund-Burguet apparatus D.Power switch K ₁Be convenient to open when user oneself takes money and goods K switch ₁, alarm is not reported to the police.Connect K switch during normal the use ₁In case switch k and k open pocket (4) when being cut, backguy (3) also can be cut off and be made K switch ₂Connect alarm equipment alarm.In case when perhaps the opening of pocket (4) draws back, plug (6) will be drawn out K switch ₃Two shell fragments (9) between and make K switch ₃Connect, alarm equipment alarm still is that pocket (4) opening edge all can be reported to the police along drawing back alarm no matter pocket (4) cuts, and can remind the user thief to be arranged at the money and goods of stealing you.The utility model is applicable to when people go out, and puts the security personnel of money and goods in pocket.
