Abstract

An anti-robbery and anti-theft mobile phone sleeve includes a phone sleeve and a hanging clamp on the sleeve, which is characterized in that a phone sleeve locking device and an alarm circuit are arranged on the hanging clamp. The phone sleeve locking device is equipped with a lock button and a press button switch to close the phone sleeve. The alarm circuit is equipped with an alarm circuit board, a battery, a micro horn and a power switch linked with the press button switch. The phone sleeve consists of a metal frame and a coat. The trip hook of the metal frame buckles with the lock button on the hanging clamp to lock the phone inside the sleeve. When the sleeve is opened, the press button on the hanging clamp is pressed to make the power switch closed. Then the alarm circuit is triggered and the alarm is warning to prevent theft. The metal frame of the phone sleeve and the coat is arranged to be releasable to prevent robbery.

Description

Anti-snatch anti-theft alarm cell-phone cover

The utility model relates to mobile phone anti-theft alarm device.

Existing anti-take off anti-theft product and be used for large-sized object more, combine with mobile phone prevent hand-set from stolen product because of its complex structure, cost is higher, is difficult for popularization on market; The small-sized theftproof antirob device that is used for mobile phone does not still have at present, and the cellphone subscriber usually is in the dock.Some lawless person utilizes despatch holder car to plunder passerby's mobile phone, and mobile phone is robbed stolen happening occasionally, and brings very big loss to the user.

The utility model purpose is to overcome the deficiency on the prior art, provides the little cost of a kind of volume low anti-snatch anti-theft alarm cell-phone cover, to satisfy cellphone subscriber's demand.

The utility model is the innovative product of existing cell-phone cover, comprise the extension folder (3) on cell-phone cover (1) and the mantle, it is characterized in that: be provided with cell-phone cover locking device and warning circuit part, they are installed in and hang on the folder (3), the mantle locking device has snap close (4) and push switch (5), in order to close cell-phone cover.Warning circuit part: warning circuit plate (11), battery (12), Microspeaker (13) are arranged, form with the mains switch (10) of push-button switch (5) interlock, when opening cell-phone cover, press the button of hanging on the folder (5), make mains switch (10) closure, trigger warning circuit, alarm equipment alarm.

Mantle (1) can be divided into mantle metal framework (7) and overcoat (9), and mantle metal framework (7) is made with sheet metal, is provided with and has contact with (8), has contact with (8) and snap close (4) closure of hanging on the folder (3), can close cell-phone cover; Mantle metal framework (7) lining overcoat (9), when external force was grabbed mobile phone, overcoat separated with mobile phone, prevents that mobile phone from being robbed.

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

Fig. 1: be the schematic diagram of its extension folder of reporting to the police.

Fig. 2: for it hangs the schematic diagram of clip back face.

Fig. 3: be its mantle metal framework schematic diagram.

Fig. 4: be its mobile phone overcoat schematic diagram

Fig. 5: be its assembled state figure.

Fig. 6: be the embodiment circuit diagram.

As shown in Figure 1: extension folder (3) top of anti-snatch anti-theft alarm cell-phone cover is provided with snap close (4) and button (5); Mains switch (10) is installed in the button (5).Hang the folder middle part and be provided with warning circuit plate (11), Microspeaker (13).Battery (12) is installed in hangs the folder afterbody.

As shown in Figure 2: the anti-extension clip back face of taking off is provided with lockhole (6);

As shown in Figure 3: the opening of mantle metal framework (7) is provided with and has contact with (8);

As shown in Figure 4: the overcoat that can loosen (9);

As Fig. 5 is the extension folder (3) of anti-snatch anti-theft alarm cell-phone cover and the assembled state figure of mantle (1), hang folder (3) and be installed on the back of mantle (1), hang and in the folder snap close (4) and knob (5) are set and are installed in mains switch (10), warning circuit plate (11), battery (12), Microspeaker (13) on the button (5).Hang the clip back face and be provided with lockhole (6), in mobile phone (2) placed mantle (1), inserted in the lockhole (6) have contact with (8) on the mantle metal framework (7), and with snap close (4) closure of hanging on the folder (3), cell-phone cover (1) is closed.In the time will taking out mobile phone (2), must press the button of hanging on the folder (3) (5), make mains switch (10) closure, trigger warning circuit and report to the police; And mantle metal framework (7) can prevent the sharp weapon cutting, and overcoat (9) adopts the device of can loosening, and prevents the violence plunder, plays the purpose of theftproof antirob.

Fig. 6 is the embodiment circuit diagram.Warning circuit adopts KD9561 four tones of standard Chinese pronunciation warning circuit, and resistance R 2 is an outer meeting resistance, and one-way SCR VT is connected in its electric power loop, and positive source is received the trigger end of controllable silicon VT by resistance R 1 and push-button switch in parallel.

The output of KD9561 circuit connects the drive circuit that is made of triode T1, T2, Microspeaker BL and load resistance R3 etc.When pressing button and make mains switch closed, can trigger controllable silicon VT conducting, the KD9561 circuit powers up work, and the alarm signal that output is set promotes loudspeaker through amplifying circuit and sends chimes of doom.

During non-alert status, mains switch cut-offs, and circuit is not worked.In the time will taking out mobile phone, press button and make the mains switch closure, trigger warning circuit and report to the police, remind owner to note, anti-ly when obtaining take off, antitheft purpose.
