Description

Anti-theft chair

Technical field

The utility model relates to a kind of Anti-theft chair.

Background technology

Traditional chair does not possess anti-theft feature, and in a lot of public places that the stream of people is more, personnel are complicated as restaurant, teahouse etc., easily there are finance and lose stolen situation.Prior art is to adopt on the chair back, to add a mode that cover entangles clothes, bag etc. and come antitheft, but there is more drawback: the one, because cover is flexible, people need to hang over article on the chair back and cover and the chair back be packaged again, its process operation trouble, expend time in, and the process that cover is taken off from the chair back also troublesome poeration, expend time in; The 2nd, narrow application range, the article that need to deposit must be able to hang on the chair back, as the bag with braces, or putting into pocket hangs up properly clothes again, once article do not have the belt of energy hook or put to enter too greatly pocket because of volume, or there is no unnecessary overcoat, cannot place; The 3rd, after article package with cover, often make the chair back protrude one, affect the especially comfort level of the chair back of seat; The 4th, people often easily forget the article in cover and cause loss; The 5th, anti-theft effect is still undesirable, and cover is likely cut open after the chair back by people, has potential safety hazard.

Utility model content

The technical problems to be solved in the utility model is, provide a kind of pick and place article convenient, applied widely, do not affect seat comfort degree, prevent that people from forgeing article and the desirable Anti-theft chair of anti-theft effect.

Technical solution of the present utility model is, a kind of Anti-theft chair with following structure is provided, it comprises seat board, it also comprises power supply and warning device, seat board is the inner hollow seat board that is provided with the storage chamber of opening upwards, on seat board, be hinged with one for covering the cover plate of storage chamber opening, on seat board, be also provided with a normally closed switch automatically disconnecting after cover plate pressurized, the non-hinged end of cover plate is pressed on the button of normally closed switch, in storage chamber, be hinged with one for the supporting plate of placing objects, in storage chamber, be also provided with an automatic closed normal open switch after supporting plate pressurized, the non-hinged end of supporting plate is pressed on the button of normal open switch, normal open switch, normally closed switch, power supply and warning device loop in series.

The operation principle of this Anti-theft chair is: people open cover plate, article are shelved on supporting plate, it is closed that supporting plate pressurized triggers normal open switch, now normally closed switch is also closed, therefore whole piece line conduction, warning device is reported to the police, illustrate and in storage chamber, deposited article, cover cover plate, people sits on the cover board, cover plate pressurized triggers normally closed switch and disconnects, and then circuit is disconnected, like this, while taking on chair, warning device is not reported to the police, and people stands up to leave, cover plate is pressurized no longer, normally closed switch is without again closed under pressure, circuit is communicated with again, warning device is reported to the police, remind in people's storage chamber and have article.

Adopt after above structure, the utility model Anti-theft chair compared with prior art, has the following advantages:

The one, when people pick and place article, only need to open cover plate, compared to existing technology thing is hung over to the chair back and put again cover, cover-plate type storage chamber of the present utility model is obviously used more convenient simple and direct; The 2nd, applied widely, do not need to be hooked on the chair back, but directly put into storage chamber, like this, no matter whether for the belt of hook, also, no matter whether can fill in pocket, all can deposit; The 3rd, article are put into after storage chamber, can not protrude cover plate, change the profile of chair, ensure the comfort level of chair; The 4th, people, rise after one's death and can remind by automatic alarm, avoid people to lose object; The 5th, anti-theft effect is desirable, and other people cannot take the article in seat board away under letting alone the prerequisite that is sitting in the people on chair, stop potential safety hazard.

As improvement, seat board comprises 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 being generally sidelong into thing of opening from cover plate, namely from the second side plate one, be sidelong thing, and supporting plate is just hinged on the second side plate of this side, like this, can avoid the object of putting into from the gap between supporting plate and side plate, to fall into supporting plate below.

As improving, warning device is the warning fluorescent tube being fixed on the chair back again, like this, can effectively to people, remind, and can as alarm, not manufacture noise again.

Shown in figure 1, seat board, 2, storage chamber, 3, cover plate, 4, normally closed switch, 5, supporting plate, 6, normal open switch, 7, base plate, the 8, first side plate, the 9, second side plate, 10, warning fluorescent tube.

The specific embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.

The utility model Anti-theft chair as shown in Figure 1 and Figure 2, it comprises seat board 1, it also comprises power supply and warning device.Seat board 1 is the inner hollow seat board 1 that is provided with the storage chamber 2 of opening upwards.On seat board 1, be hinged with one for covering the cover plate 3 of storage chamber 2 openings, specifically, seat board 1 comprises a base plate 7 and four side plates, and base plate 7, four side plates and 3 six panels of a cover plate have surrounded storage chamber 2.Cover plate 3 and the first side plate 8 tops are hinged.On seat board 1, be also provided with a normally closed switch 4 automatically disconnecting after cover plate 3 pressurizeds, 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-hinged end of cover plate 3 is pressed on the button of normally closed switch 4.From general knowledge, normally closed switch 4 is inner exists an elasticity reset device as stage clip or reed, this elasticity reset device applies the elastic force making progress to button, the size of this elastic force just equals the pressure of 3 pairs of buttons of cover plate, like this, and button stress balance, once cover plate 3 is because having placed article pressurized, the pressure of 3 pairs of buttons of that cover plate will be greater than the elastic force making progress that button is subject to, and causes button pressed, impels normally closed switch 4 to disconnect.

In storage chamber 2, be hinged with one for the supporting plate 5 of placing objects, supporting plate 5 is hinged on the second side plate 9.In storage chamber 2, be also provided with an automatic closed normal open switch 6 after supporting plate 5 pressurizeds, normal open switch 6 is positioned on base plate 7, and the non-hinged end of supporting plate 5 is pressed on the button of normal open switch 6.Equally from general knowledge, also there is the elastic force that button is made progress in normal open switch 6 inside, the pressure equal and opposite in direction of this elastic force and 5 pairs of buttons of supporting plate, like this, once shelve article on supporting plate 5, the pressure of 5 pairs of buttons of supporting plate is just greater than the elastic force of normal open switch 6 inside, makes button pressed, normal open switch 6 closures.Normal open switch 6, normally closed switch 4, power supply and four unit Series of warning device form loop.Warning device is the warning fluorescent tube 10 being fixed on the chair back.
