Description

Anti-theft television, videocorder case

The utility model relates to a kind of TV, video recorder secure device, particularly relates to TV, video recorder Theft-proof cabinet.

Along with the deep development of reform and opening-up, living in constantly of the people improves, and television set, video recorder have entered huge numbers of families, have brought joy to people.But also brought the problem of saving from damage, still do not found safety, the anti-theft device sale of television set, video recorder in the market.

The purpose of this utility model is to provide a kind of can lay television set, video recorder, has the device of anti-theft feature again, i.e. TV, video recorder Theft-proof cabinet.

The utility model can be used in huge numbers of families, and it is generous that it is handsome in appearance, new and original, conveniently moving, and it can place television set, video recorder, is placed on family Anywhere, and is a furniture attractive in appearance; Its safety, reliable has anti-dismounting, anti-ly moves, anti-ly moves function, as long as dismantles, moves, moves all and can report to the police automatically; The utility model uses the 6V power supply, and power consumption is low, and the life-span is long; The utility model also can be placed other more valuable article except that placing safely television set, the video recorder.

The utility model is achieved in that on the top of cabinet television set safety grid 1 is housed that it also is anti-theft switch K1 that Theftproof bolt 3(is housed at the base angle of safety grid 1); The video recorder storage chamber is equipped with anti-theft guardrail 2 at the cabinet middle part in the front portion of storage chamber; Warning device 6 is equipped with in the bottom of cabinet, and mobile alarm switch 7(also is anti-theft switch K2), moving alarm switch 8(also is anti-thefting alarming switch K3), and handle alarm switch 5(also is alarm switch K4), door lock 4 is housed on the cabinet lower gate; For conveniently moving, four universal wheels are adorned in the bottom of the utility model 4.

Accompanying drawing 1 is a structural representation of the present utility model.

Accompanying drawing 2 is circuit theory diagrams of warning device of the present utility model.

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

The utility model is a cupboard handsome in appearance, on the top of cabinet safety grid 1 is housed, safety grid 1 is to be linked by two above metal frameworks, after putting television set cashier's office in a shop, install safety grid 1, can be firmly on cabinet with television set, and do not influence normally watching of television set, it also is anti-theft switch K1 that Theftproof bolt 3(is housed at the base angle of safety grid); The video recorder storage chamber is at the cabinet middle part, and metal (for example stainless steel) railing 2 is equipped with in the front portion of storage chamber, railing 2 movable loading and unloading, but after only taking television set away, just can lay down railing 2; In the bottom of cabinet warning device 6 is housed, mobile alarm switch 7(also is alarm switch K2), to move alarm switch 8(also be alarm switch K3), and handle alarm switch 5(also is alarm switch K4); Metal door is equipped with in the bottom of cabinet, and door lock 4 is housed on metal door, and total power switch K0 is housed on door lock 4; Be conveniently moving, 4 universal wheels are equipped with in the bottom of cabinet.Warning device of the present utility model is by crystal villous themeda BG1--BG9, resistance R 1--R13, and capacitor C 1--C5, and inductance L, relay J and loudspeaker Y constitute.Wherein BG1, BG9 constitute trigger input circuit, BG2--BG4, resistance R 3--R8, capacitor C 1--C3 constitute two saw-toothed wave generators, BG5--BG6, R9--R12, capacitor C 4--C5 constitute square-wave generator, and BG7--BG8, resistance R 13, inductance L constitute compound villous themeda amplifying circuit.

After television set, video recorder placed, owner went out, and door lock 4 is locked, and this moment, total power switch K0 connected, and whole warning device is in treats duty.If someone wants to take away television set or video recorder, then must lay down safety grid 1, or move, or move cabinet, as long as do above-mentioned action, anti-theft switch K1 then, K2, K3 just has an anti-theft switch or a plurality of anti-theft switch to connect, if the handle on someone the automatic rotation cabinet lower gate, then handle alarm switch K4 also can connect, and this moment, power supply E will insert trigger input circuit, make the BG9 conducting, power supply inserts other circuit, and saw-toothed wave generator produces sawtooth waveforms, acts on square-wave generator, amplify the promotion loudspeaker by composite amplifier then and send audible alarm, because relay J has self protective function, so though stop to move, move, actions such as rotation, K1--K4 all disconnects, but warning device is still in running order, chimes of doom is constant, has only with key master switch K0 is disconnected, and whole warning just finishes.

The used electric elements of the utility model circuit all do not have specific (special) requirements, and are on sale on the market, just the power of BG8 bigger slightly for well.
