The utility model comprises a cover body and an alarm theft-proof device, wherein, the alarm theft-proof device comprises a power supply connected through a wire, a music module, a buzzer, a power supply switch and a magnetic switch, wherein, the music module, the buzzer and the power supply are arranged in the cover body and an interlayer. The two switches are arranged on the surface of the cover body. The utility model solves the problems of high cost, bad theft-proof effect and inconvenient utilization of like products.

Description

The electronic warning and anti-theft cell-phone cover

(1) technical field: the electronic warning and anti-theft cell-phone cover belongs to the articles for use packing appliance, in particular for antitheft packing appliance.(B65D)

(2) technical background: at present articles for use packing appliance such as the mobile phone that uses of people such as cell-phone cover, generally do not have an anti-theft feature, the hand-set from stolen phenomenon often takes place, even the phenomenon of same individual continuous stolen multi-section mobile phone in a period of time takes place, the problem that therefore solves antitheft mobile phone is extremely urgent.Notification number is that the utility model patent of CN2464663Y discloses a kind of antitheft anti-mistake leather sheath, comprises body and warning device, and warning device comprises the press-type switch, electronic circuit board, siren, delay switch, the power supply that have compressing tablet that is provided with in the housing.When the article in the leather sheath were removed, alarm generation buzzing reminded owner to seek article, if owner normally uses, can press the delay switch button, and alarm circuit interrupts resuming work after 3-5 minute.There is following shortcoming in this leather sheath: (1) structure and circuit complexity, and processing is inconvenient, the processing cost height; (2) this leather sheath just gives the alarm when article are removed, and it is untimely to report to the police, and anti-theft effect is not good; When (3) normally using, can only delay time a few minutes, use inconvenience, show inconvenience especially at special occasions especially meeting-place by delay switch.

(3) summary of the invention: problem to be solved in the utility model is to overcome above-mentioned deficiency, provides that a kind of processing cost is low, easy to process, good anti-theft effect, cell-phone cover easy to use.Its technical scheme is as follows:

The electronic warning and anti-theft cell-phone cover comprises body and alarm against theft, and its key technology is that alarm against theft comprises power supply, music module, buzzer, the mains switch K that connects by lead ₁With alarm switch K ₂One end of music module connects K switch ₁And K ₂, the other end connects buzzer.Music module, power supply and buzzer place in the interlayer of body, alarm switch K ₂Be installed on the protecgulum of body mains switch K ₁Be installed on the back side of body.

(5) embodiment;

Embodiment one:

Referring to accompanying drawing, the utility model comprises body 1 and alarm against theft, and its key technology is that alarm against theft comprises power supply 6, music module 5, buzzer 7, the mains switch K that connects by lead 4 ₁With alarm switch K ₂, an end of music module 5 connects K switch ₁And K ₂, the other end connects buzzer 7.Music module 5, power supply 6 and buzzer 7 place in the interlayer 2 of body 1, alarm switch K ₂Be installed on the protecgulum 3 of body mains switch K ₁Be installed on the back side (comprising the belt card backside) of body 1.Mains switch K ₁Be to place an insulating trip 9 between two contacts 8, insulating trip 9 inserts the interlayer of bodies from the opening 10 on the body outer wall, and insulating trip 9 can move up and down in interlayer through this mouth.Alarm switch K ₂Being magnetic switch, is to establish magnet in the one side at the hasp place of protecgulum 3, and corresponding another side is fixed the copper sheet or the aluminium flakes of two butt joints and made reed 11, and wherein a reed end is fixed an iron plate 12.K switch ₂Also can adopt contact switch, power supply 6 of the present utility model and music module 5 can also be the integral body that is connected as a single entity, and have preformed hole 14 and use for changing power supply on the body outer wall of placing power supply 6 places.

Embodiment two:

Referring to Fig. 5, an end of music module 5 of the present utility model connects reserves plug 13, directly inserts the buzzer or the vibrating device of mobile phone, and other structure is identical with embodiment one structure.The utility model music module 5 adopts commercially available music module.The utility model alarm against theft also can be used for packing appliances such as satchel, wallet.

The utility model operation principle:

Under the normal condition, the protecgulum 3 of cell-phone cover closes up, because magneticaction, the iron plate 12 of reed 11 ends is by magnetic, and the reed of butt joint is because the elastic force effect separately, makes K ₂Be in off-state, this moment no power, buzzer 7 can not reported to the police; When opening when burglar's desire pilferage mobile phone and with cell-phone cover, because the external force effect, iron plate 12 resets, and reed 11 also resets, and two butt joint reeds connect K switch ₂Closure, energized, music module 5 work, buzzer 7 warning reminding owners prevent to steal, if use contact switch, when the robber opens cell-phone cover and contacts the switch of protecgulum inboard, K ₂Closure, buzzer warning; When owner normally uses, lift insulating trip 9, make it between two contacts 8, and two contacts are disconnected, power supply promptly disconnects, and can arbitrarily grasp alarm condition, if think the power turn-on switch on the contrary, then make insulating trip 9 not between two contacts 8, the contact of two contacts, power supply is promptly connected.

The utility model good effect: 1, structure and circuit are very simple, and be easy to process, thereby be processed into This is low, and common people can bear; 2, when cell-phone cover just is opened and report to the police, report to the police in time anti-theft effect Good, take precautions against in possible trouble; 3, the setting of power switch and magnetic switch can arbitrarily arrange alarm condition, makes With making things convenient for, saving worry; 4, in public places, magnetic switch also can remind owner to build cell-phone cover.
