Description

Anti-theft chair

Technical field

The present invention relates to a kind of Anti-theft chair。

Background technology

Traditional chair does not possess anti-theft feature, and more a lot of artificial abortions, personnel are complicated public place such as restaurant, teahouse etc., it is easy to occur finance to lose stolen situation。Prior art is utilized on the chair back adding the mode that clothes, bag etc. entangle by a cover and comes antitheft, but there is more drawback: one is flexible due to cover, people need to hang over article and cover and the chair back are packaged on the chair back again, its process operation trouble, expend time in, and the process also troublesome poeration that cover is taken off from the chair back, expend time in；Two is narrow application range, it is necessary to the article deposited must be able to hang on the chair back, such as the bag with braces, or put into pocket to be hung up properly by clothes again, once article do not have the belt of energy hook or because volume is not placed into too greatly pocket, or there is no unnecessary overcoat, then cannot place；Three is after article cover packages, often such that the chair back protrudes one piece, affects the comfort level of the seat especially chair back；Four are people's article of tending to forget in cover and cause loss；Five is that anti-theft effect is still undesirable, and cover is likely cut open after the chair back by people, there is potential safety hazard。

Summary of the invention

The technical problem to be solved in the present invention is to provide one and picks and places that article are convenient, applied widely, do not affect seat comfort degree, prevent people from forgeing article and the desirable Anti-theft chair of anti-theft effect。

The technical solution of the present invention is, a kind of Anti-theft chair with following structure is provided, it includes seat board, it also includes power supply and alarm device, seat board is the hollow seat board that inside is provided with the storage chamber of opening upwards, seat board is hinged with one piece of cover plate for covering storage chamber opening, seat board is additionally provided with one when the normally closed switch automatically disconnected after cover plate pressurized, the non-articulated side pressure of cover plate is on the button of normally closed switch, one block of supporting plate for placing objects it is hinged with in storage chamber, one it is additionally provided with when the normal open switch automatically closed after supporting plate pressurized in storage chamber, the non-articulated side pressure of supporting plate is on the button of normal open switch, normal open switch, normally closed switch, power supply and alarm device loop in series。

The operation principle of this Anti-theft chair is: people open cover plate, by article rest on supporting plate, supporting plate pressurized triggers normal open switch Guan Bi, now normally closed switch is also Guan Bi, therefore whole piece line conduction, alarm device is reported to the police, illustrate to house in storage chamber article, cover cover plate, people sits on the cover board, cover plate pressurized triggers normally closed switch and disconnects, and then circuit is disconnected, so, when taking on chair, alarm device is not reported to the police, and people stands up to leave, cover plate is pressurized no longer, re-close under normally closed switch no pressure, circuit connects again, alarm device is reported to the police, remind in people's storage chamber and have article。

After adopting above structure, Anti-theft chair of the present invention compared with prior art, has the advantage that

One is that people are when picking and placeing article, it is only necessary to opening cover plate, compared to existing technology thing is hung over the chair back and put cover again, the cover-plate type storage chamber of the present invention substantially uses more convenient simple and direct；Two is applied widely, it is not necessary to is hooked on the chair back, but is directly placed into storage chamber, so, no matter either with or without the belt for hook, regardless of whether filling in pocket, all can deposit；Three is after article put into storage chamber, will not protrude cover plate, changes the profile of chair, ensures the comfort level of chair；Four is rise people to remind by automatic alarm after one's death, it is to avoid people lose object；Five is that anti-theft effect is desirable, and other people cannot take the article in seat board away under the premise letting alone the people being sitting on chair, stops potential safety hazard。

As improvement, seat board includes a base plate and four side plates, cover plate and the first side plate top are hinged, supporting plate is hinged on the second side plate parallel with the first side plate, opens cover plate, and people are usually the side opened from cover plate and put into thing, namely it is sidelong thing from the second side plate one, and supporting plate is just hinged on the second side plate of this side, so, it is avoided that the object put into is fallen into below supporting plate from the gap between supporting plate and side plate。

As improving, alarm device is the warning fluorescent tube being fixed on the chair back again, so, effectively can remind to people, will not manufacture again noise as alarm。

Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, the invention will be further described。

Anti-theft chair of the present invention as shown in Figure 1 and Figure 2, it includes seat board 1, and it also includes power supply and alarm device。Seat board 1 is the hollow seat board 1 of the internal storage chamber 2 being provided with opening upwards。Being hinged with one piece of cover plate 3 for covering storage chamber 2 opening on seat board 1, specifically, seat board 1 includes a base plate 7 and four side plates, 7, four side plates of base plate and 3 six panels of a cover plate and defines storage chamber 2。Cover plate 3 and the first side plate 8 top are hinged。Seat board 1 is additionally provided with one when the normally closed switch 4 automatically disconnected after cover plate 3 pressurized, normally closed switch 4 is arranged on the second side plate 9 parallel with the first side plate 8, the button of normally closed switch 4 is higher than the end face of the second side plate 9, and the non-articulated side pressure of cover plate 3 is on the button of normally closed switch 4。From general knowledge, normally closed switch 4 is internal exists elasticity reset device such as a stage clip or reed, this elasticity reset device applies an elastic force upwards to button, the size of this elastic force is equal to the cover plate 3 pressure to button, so, and button stress balance, once cover plate 3 is because placed article and pressurized, the elastic force upwards that the pressure of button will be subject to by that cover plate 3 more than button, causes button pressed, promotes normally closed switch 4 to disconnect。

Being hinged with one block of supporting plate 5 for placing objects in storage chamber 2, supporting plate 5 is hinged on the second side plate 9。Being additionally provided with one in storage chamber 2 when the normal open switch 6 automatically closed after supporting plate 5 pressurized, normal open switch 6 is positioned on base plate 7, and the non-articulated side pressure of supporting plate 5 is on the button of normal open switch 6。Same from general knowledge, normal open switch 6 is internal there is also one to button elastic force upwards, this elastic force is equal in magnitude to the pressure of button with supporting plate 5, so, once article shelved by supporting plate 5, the pressure of button is greater than the elastic force within normal open switch 6 by supporting plate 5 so that button pressed, and normal open switch 6 closes。Normal open switch 6, normally closed switch 4, power supply and four unit Series of alarm device constitute loop。Alarm device is the warning fluorescent tube 10 being fixed on the chair back。
