Abstract

The utility model belongs to a commodity safety monitoring device, relating to a safety theft-proof button which is composed of a round-head nail and a button body, wherein, the button body is composed of a locking device and an amorphous magnetic strip. Compared with the prior art, the utility model has the advantages of simple structure, sensitive alarm, fastness, reliability, good theft-proof effect, etc., and can be suitable for various emporiums having open type rack selling and the public places which need theft-proof protection.

Description

Safety button

The utility model belongs to the business security field of surveillance systems.It is parts in the burglary protection system for commodities.

Along with open-shelf is sold goods, free, supermarket increasing, it is serious day by day that commodity are lost phenomenon, and the manager in market is puzzled one's brains.

The at present commercial antitheft radio system that generally adopts.The safe electronic button, be to adopt thin copper conductor and electric capacity to link together, antidetonation, shock resistance are poor, in addition, very easily produce the shielding phenomenon again for metallic article and the polybag that has a metal coating, also have, mostly existing locking device is to adopt two steel balls and nail pin chucking, exists contact-making surface little, poor stability, easily pull out tack, stud, thereby do not reach antitheft purpose.The part of this safe electronic button mostly is car system simultaneously, complex process.

The purpose of this utility model is to solve the deficiency of known technology, thereby provides a kind of technology simple, is quick on the draw, and uses reliable, firm safety button.

The purpose of this utility model realizes with following mode:

Safety button is made up of tack, stud 1 and button body 2, wherein has a ring-type amorphous state magnetic stripe 4 in the button body, and the button body bottom has locking device 3.Locking device 3 is positioned at the button body bottom, and cylindrical interior cover 7 penetrates spring 8 upper ends, and spring 8 lower ends are enclosed within on the cylinder of lower cover 9 bottom centre, put at least 3 steel balls 6 in bell-jar 5, and bell-jar and lower cover button limit combine.

On the finer and closely woven fabric of braiding, safety button is installed and can be used 3 steel balls, like this nail pin of tack, stud can make thinner, do not hinder fabric, but general safety button to be put into 4 steel balls.

The utility model compared with prior art has following advantage:

1. the amorphous state magnetic stripe is contained in the button body, simple in structure, the sensitivity of reporting to the police.

2. component processing mostly is punching out, and technology is simple.

3. button is difficult for drawing back, and anti-theft strengthens.

4. can adopt very thin tack, stud, not hinder fabric.

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

Fig. 1 is the utility model tack, stud and button body cutaway view.

Fig. 2 is the utility model locking device cutaway view.

Fig. 3 is the utility model locking device structure stereogram.

According to Fig. 1, Fig. 2, Fig. 3, shown in, the utility model is made up of tack, stud 1 and button body 2.Button body 2 comprises: locking device 3, button body 2 and ring-type amorphous state magnetic stripe 4.

Wherein locking device 3 comprises: bell-jar 5, steel ball 6, cylindrical interior cover 7, spring 8, lower cover 9.

Locking device 3 is in the button body bottom, outer shape can be injection molded into bullet or hemisphere, the amorphous state magnetic stripe is injection-moulded in button body top, but the outer shape injection moulding on button body top becomes round platform, elliptical table, Fang Tai, rectangular or terrace with edge, and button body 2 is with ABS engineering plastics injection molded.

Cover 7 bottoms in cylindrical are penetrated spring 8 upper ends, and spring 8 lower ends are enclosed within on the cylinder of lower cover 9 bottom centre, put at least 3 steel balls 6 in bell-jar 5, and bell-jar 5 forms Fig. 2 shape with lower cover 9 button limits.

According to the above, tack, stud 1 runs through in the middle of 5,4 steel balls 6 of bell-jar of Fig. 3 locking device 3, cylindrical interior cover 7, the spring 8.Spring 8 upwards promotes cylindrical interior cover and 4 steel balls 6, steel ball 6 locking tack, stud 1.Locking device pulling force in tack, stud pin and the button body is greater than 25Kg.

Because the magnetic stripe that has an amorphous material to make in the button body of safety button.When safety button passes through the outlet passageway, through being arranged on the sniffer of outlet, sniffer is arranged in the outlet passageway, sales area, produce the alternating current-direct current magnetizing field during operate as normal, safety button is to be buckled on the commodity such as clothes, pin yarn fabric the magnetic stripe that has an amorphous material to make in the safety button.When above-mentioned commodity being stolen out the passageway without the payment desire, the alternating current-direct current magnetizing field makes the magnetization curve generation nonlinear change of amorphous material, thereby the magnetic field of channel space is changed, at this moment it is bright that sniffer will send the warning red light, alarming horn sends alert sound, door locking device action, commodity can be intercepted and captured, and not stolenly go out; As untiing safety button easily by remover through normal payment shop assistant, commodity just can normally pass through the exit.

Claims
