Anti-theft label

Abstract

The invention discloses an anti-theft label for guarding against theft by locking security nails tightly; which is widely used for preventing commodities in shops or supermarkets from being stolen. The anti-theft label comprises a casing composed of an upper cover and a base with a steplike inner cavity; a coil alarm is provided between the upper cover and the base; the anti-theft label further comprises a security nail locking mechanism which is provided with a transverse blocking device, wherein, the transverse blocking device is linked with a pneumatic mechanism which comprises an air channel arranged on the casing or in the inner cavity of the casing; an air channel opening at one side is arranged beside the transverse blocking device; an air inlet and outlet at the other side is communicated with an external air pump; one or a plurality of the air channels are provided. The anti-theft label of the invention has the advantages that the pneumatic mechanism is adopted and matched with the former magnetic mechanism; the pneumatic mechanism is required to be matched with the air pump and the function of unsealing the anti-theft label can be realized by communicating a nail puller with the air pump, the anti-theft label is safer and more reliable and has elaborate design; the nail puller is added with a common valve structure, therefore, the usage is more convenient, the technology is mature, the implementing effect is better and structure is beautiful.

Description

technical field [0001] The invention relates to an anti-theft label, which is widely used for anti-theft of commodities in stores or supermarkets. Background technique [0002] In the commodity market, anti-theft tags are widely used. One is a locking anti-theft tag. This type of tag is made into a locking device with a specific mechanical structure. The anti-theft tag is fixed on the On the product, only the corresponding magnetic opening tool can be used to open this kind of anti-theft label, and customers cannot open the anti-theft label with bare hands, so as to achieve the purpose of anti-theft. The second is an alarm-type anti-theft label, the principle of which is to set electronic components or other similar alarm components in the label. When the anti-theft label is opened in an abnormal way, the alarm component will send out an alarm signal, so that the theft can be detected in time, thereby preventing theft. With anti-theft function. The third is a comprehensive...

Problems solved by technology

[0003] The disadvantage of magnetic anti-theft tags is that the existing anti-theft tags do not have absolutely safe anti-theft functions. Since this type of anti-theft tag can be opened by any magnet, it can be opened by others with a built-in magnet, making the anti-theft tag Lost the anti-theft function

[0005] However, this kind of anti-theft label g
