Abstract

The utility model relates to an anti-theft alarm case with electric action. The inner side wall of the case is provided with a power supply, a horn, and a circuit board. The inner part of a handle is provided with a magnetic control switch, one pad foot at the bottom of the case is provided with a position switch, and the magnetic control switch and the position switch are electrically connected with the power supply and the circuit board. The utility model has the advantages that the position of the installation of the switch is hidden with seeing difficulty, the multiplex switching control is arranged, and the alarm can be sent out at the time of seizing or stealing. Therefore, the utility model is helpful for preventing the crime, and the property safety can be ensured.

Description

Anti-theft alarm case

The utility model relates to one and prevents the alarm stolen, specifically a kind of burglar alarm case of electro ultrafiltration.

General portable case and bag are used for holding some more valuable article and coins more, therefore also just become thief's main goal of attack.So it is very general to wrap the various alarms of installation at suitcase in recent years, and to preventing to steal certain effect of having played.Comparatively Xian Jin warning case and bag are that attaching has power supply on box wall, and loudspeaker and wiring board have jackswitch on the face before case, the terminal tether of inserting handle, and on the person's wrist that is placed in the suitcase, some also is equipped with level switch in case.When the people plundered suitcase, inserting handle was deviate from like this, produced to report to the police.Or break away from human body and when keeping flat, start level switch when case and bag, then case and bag are once erect, and the mercury-wetted contact closure is connected circuit, gives the alarm.The shortcoming of this structure is that inserting handle is placed on the wrist, and target is more remarkable, and illustrating has valuables in the case, easily provide target for the thief; Case and bag work for making mercury contact switch before hand in addition, also need uncap and pull switch in the case.This causes content product " exposure " again, and owner is unfavorable to case.

It is more hidden that the purpose of this utility model just provides a kind of switch setting, uses convenient safe burglar alarm case and bag.

The utility model is achieved in that attaching power supply on box wall, and loudspeaker and wiring board are equipped with magnetic switch in the case handle, on one at the bottom of the case pad pin position switch is housed, and two switches keep being electrically connected with power supply and wiring board.Because the switch installation site is hidden, difficult behaviour realizes, and grabs or when stealing suitcase, all can make switch closure as criminal, and audible alarm is sent in the circuit connection.

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

Fig. 1 is this warning box structure synoptic diagram;

Fig. 2 is the electrical schematic diagram of this warning box.

As shown in Figure 1, the utility model is that power supply 2 is installed on the case and bag madial wall, and loudspeaker 3 and wiring board 4 are equipped with magnetic switch K1 in handle 5.The lead that connects K1 is located metal rotating shaft and is led to the case and bag inboard along the handle internal communication, keeps being electrically connected with power supply and wiring board.Magnetic switch can be contained in the following or side of handle center, possesses magnetic patch in the suitcase person hand, just in time K switch 1 is inhaled and opens, and cuts off circuit.Magnetic patch can be arranged on the ring ring as required, is easy to carry to have simultaneously disguise again.Grab or stealer owing to do not know inside information, detinue behind the case and bag because of disconnecting magnetic switch, cause the warning horn warning.For further improving security, can on K switch 1, install a little magnetic patch additional, make magnetic patch and little magnetic patch in the person's hand that has only the suitcase could disconnect K1 when there is a natural attraction between the sexes, the magnetic force size of the little magnetic patch that installs additional simultaneously will guarantee also can not move when common magnetic conductor is close.

On one at the bottom of case pad pin 7, position switch K4 is housed also.When case and bag contacted to earth, the pad pin landed, and K4 is backed down, and circuit disconnects.When mentioning case and bag, the pad pin of dress K switch 4 is unsettled, and a loosening downwards displacement is arranged, and makes the K4 closure.Disconnect (case and bag owner mention) as K1 this moment, then do not report to the police; As the K1 closure, promptly non-owner steals case, and then circuit is linked up, and reports to the police.

For preventing that the insider from stealing case and bag, promptly it is grasped situation that magnetic switch opens and closes main points and K1 is disconnected and takes place, and on face case lock 6 K switch 2 can be housed before case, and K2 is parallel to the two ends of K switch 1 by lead, and this switch opens and closes by key.After the person that holds the case was with key Closing Switch K2, no matter the K1 open and-shut mode how, needs only suitcase, the K4 closure was sent warning.Can install a total power switch K3 additional in the case and bag inboard.

Fig. 2 has provided power supply reason figure of the present utility model.As shown in Figure 1, major component IC adopts integrated circuit PS-285, poster or alarm song can have been imported in advance, be connected with resistance R 1 around IC, triode BG1 and power supply E, loudspeaker are connected on the collector of BG1, power supply can adopt dry cell, K switch 1K2 and connect the back be connected in series with K3, be connected in power supply E, K4 is connected with IC.

This device is hidden because of the contactor installation site, is difficult for noticeablely, and multi-breal switch control is arranged, and grabs or all can report to the police during stealing criminal, thereby help discontinuation of a crime, ensures property safety.

Claims

1, a kind of burglar alarm case, attaching has power supply on box wall, and loudspeaker and wiring board is characterized in that in the handle of this case magnetic switch K1 being housed, on one at the bottom of the case pad pin position switch K4 is housed, K switch 1 and K4 keep being electrically connected with power supply and wiring board.

2, burglar alarm case according to claim 1 is characterized in that a case of face is locked before case K switch is housed ₂, K ₂Be parallel to K switch ₁Two ends.
