Description

A kind of commodity anti-theft nail

Technical field

Anti-theft device when the utility model relates to a kind of commercial articles vending.

Background technology

Leave some commodity on the open shelf of places of business such as supermarket in, such as shoes, clothes etc., businessman often adopts antitheft nail is set on these commodity in order to prevent from illegally to be taken out of the place of business.These antitheft nails comprise the head of a nail, nail bar and nail bar binding clasp.In use, such as clothes class commodity, the nail bar passes the lining of clothes, and lining is sandwiched between the head of a nail and the nail bar binding clasp.When payment,, binding clasp is unclamped by specific purpose tool, take off antitheft nail, otherwise, when clothes are illegally taken out of the place of business, the anti-thefting monitoring door of place of business can be sensed the signal that the electronic article surveillance tag thing in the nail bar binding clasp is launched, and the prompting commodity are stolen.But this antitheft nail when illegally being pulled out in place of business, just can't play antitheft effect.And, for the commodity of complete sale, or the commodity of forming by the article of several separation, this antitheft nail is difficult to take into account the antitheft of each assembly, unless each assembly is all installed antitheft nail respectively, but this has increased cost again, and operation is trouble also.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of good anti-theft effect and can take into account the commodity anti-theft nail of many products.For this reason, the utility model is by the following technical solutions: comprise the head of a nail, nail bar, it also is provided with housing, the head of a nail is located in the housing, the nail bar passes in housing and cooperates with nail bar binding clasp, also is provided with warning circuit in the housing, is provided with the warning triggering conductor that matches along the direction of illegally stirring of antitheft nail, be provided with the rubber-like insulator between conductor, the triggering conductor of an end is subjected to head of a nail effect; Described antitheft nail also is provided with and stretches out the outer antitheft rope of conduction of housing, and warning circuit is connected with the antitheft rope of conduction, and antitheft rope is formed with ring outside housing.Owing to adopt technique scheme, can need antitheft together article to link together with antitheft rope, adopt an antitheft nail can play antitheft effect to the company commodity.When the antitheft rope of conduction is illegally cut off, can trigger warning circuit, there is illegal act to take place by the chimes of doom prompting, when nail bar binding clasp by illegally when the nail bar is pulled out, insulator is compressed, and reports to the police to trigger conductor and contact, trigger warning circuit, by chimes of doom prompting illegal act, prevent from illegally to be removed in antitheft nail in place of business the perfect anti-theft feature of antitheft nail.

Rubber-like insulator described in the utility model general reference can compressed insulation system, it can be made of a part, such as the electro-insulating rubber pad, also can cooperate and form, constitute by insulator that cooperates with the triggering conductor of reporting to the police and the flexible member between the insulator such as it by several parts.

Being subjected to the triggering conductor of head of a nail effect, can be the sheet metal that is enclosed within on the nail bar, also can be set directly on the head of a nail or the nail bar to move along with the nail bar head of a nail.

Fig. 3 is the power circuit of warning circuit shown in Figure 2.

Embodiment

With reference to accompanying drawing.The utility model comprises the head of a nail 1, nail bar 2, it also is provided with housing 3, the head of a nail is located in the housing, the nail bar passes in housing and cooperates with nail bar binding clasp 4, also be provided with warning circuit in the housing, the direction of illegally stirring along antitheft nail is provided with the warning triggering conductor 5,6 that matches, and the triggering conductor 5 that is provided with rubber-like insulator 7, one ends between conductor is subjected to head of a nail effect; Described antitheft nail also is provided with and stretches out the outer antitheft rope 9 of conduction of housing, and warning circuit is connected with the antitheft rope of conduction, and antitheft rope is formed with ring 91 outside housing.

The described triggering conductor 5 that is subjected to head of a nail effect is for being enclosed within the sheet metal on the nail bar, and the other end that cooperates with the aforementioned metal sheet triggers conductor 6 and is located on the wiring board 10 of warning circuit, and it can be the bump on the wiring board.

Described rubber-like insulator adopts the electro-insulating rubber pad in the present embodiment, such as the silica gel sheet.

Present embodiment is provided with the insulator mount pad 31 that is connected with housing, and described wiring board is provided with the hole 20 that cooperates with mount pad, and mount pad is in the described hole, and described insulator is located on the mount pad, and the nail bar passes insulator, mount pad and passes housing.Like this, insulator is installed firm, and the utility model is reported to the police reliable sensitive.

Under normal circumstances, insulator will be reported to the police and be triggered conductor 5,6 and separate, in case have the people to attempt illegally to remove antitheft nail, when nail bar binding clasp by illegally when the nail bar is pulled out, because the clamping of 4 pairs of nail bars of binding clasp is very tight, in pulling out process, the nail bar head of a nail certainly will move to the binding clasp direction, thereby compressed insulator is reported to the police and triggered conductor 5,6 contacts, trigger warning circuit, by chimes of doom prompting illegal act.

Present embodiment has provided a kind of preferable arrangement of parts mode, particularly triggers the layout of conductor 5,6 and rubber-like insulator 7 to reporting to the police.Certainly, these parts also can be arranged on other positions in the housing, need only to guarantee when nail bar head of a nail energy compressed insulator 7 when the binding clasp direction is moved, and triggering conductor 5,6 contacts of reporting to the police are got final product.

With regard to warning circuit, can continue for some time the warning circuit that sends chimes of doom after can adopting some to trigger, these circuit can obtain in the prior art, Fig. 2 has also showed a kind of warning circuit, the power positive end 201 of drawing reference numeral 101 expression map interlinkings 3, power supply is a battery, drawing reference numeral 30 expression battery carriers in Fig. 1, in this warning circuit, also be provided with warning light emitting diode 8, when nail bar binding clasp by illegally when the nail bar is pulled out, insulator is compressed, conductor 5,6 contacts are with the warning circuit conducting, secondary actuator 104, flow to triode 102 high-frequency pulse signals, hummer 103 pipes, by chimes of doom prompting illegal act light emitting diode 8 luminous warnings simultaneously.In Fig. 2, drawing

reference numeral

105 and 106 be in the warning circuit with the conduction antitheft rope 9 tie point, when the conduction antitheft rope 9 cut off, 91 cut off such as ring, also can secondary actuator 104, flow to triode 102 high-frequency pulse signals, hummer 103 pipes, light emitting diode 8 luminous warnings.

In the present embodiment, warning circuit is provided with the supply voltage of test warning circuit and the voltage comparator 107 that is connected with the trigger of warning circuit.When supply voltage is lower than a certain numerical value, energy secondary actuator 104, light emitting diode 8 flickers, hummer 103 pipes, and prompting needs to change battery.
