Embodiment Construction

[0021] It can be seen from the figure that the steel sheet type anti-theft tag includes a nail cap 1 with a nail rod 1-1 protruding from the cap and a nail holder 10 clamped and matched with the nail rod; The clamping rod mechanism and the circuit coil of the nail rod (the circuit coil is omitted in the figure), the top of the nail holder housing is shaped on a perforation 2-1, and the aforementioned nail rod passes down through the perforation and enters the nail holder to be connected with the clamp. The function of the rod mechanism; the above structure is similar to the structure of the existing anti-theft label.

[0022] The present invention is formed with several circles of grooves 1-11 on the nail shank, and these grooves circle around the outer circumference of the nail shank. The width and depth of the grooves are determined according to the needs. Between each circle of grooves Be separated by a certain distance (the distance can be determined according to needs). ...

Abstract

The invention relates to a theftproof label with the characteristics of good theftproof performance and simple structure. The technical scheme is as follows: the label comprises a nail head and a nail clamping seat matched with a nail rod by clamping, wherein the nail rod overhangs and protrudes from the cap of the nail head; a rod clamping mechanism and a circuit coil are arranged in the nail clamping seat; the top end of the shell of the nail clamping seat is provided with a hole; and the nail rod penetrates through the hole downwards to enter into the nail clamping seat to be clamped, pressed and fixed by the rod clamping mechanism. The label is characterized in that a plurality of circles of grooves surrounding the outer circumference surface are arranged on the nail rod; the grooves are separated by certain space; the rod clamping mechanism comprises two sheet steel which is arranged in the form of double doors and can respectively rotate; the sides of the seam crossing of the two sheet steel are provided with semi-circular nicks; a locating piece which limits the sheet steel in the horizontal folding states and allows the sheet steel to rotate below the horizontal plane is arranged above the sheet steel; and a spring which pushes the sheet steel upwards so as to fold the two sheet steel is arranged below the two sheet steel.

Description

technical field [0001] The invention relates to an anti-theft device, in particular to a label used for anti-theft of commodities in shopping malls. Background technique [0002] Chinese patent application document (application number 200720113287.4) discloses a kind of anti-theft label. The label includes a nail cap with a nail rod protruding from the cap and a nail holder that clamps and cooperates with the nail rod; a steel ball clamp for clamping the nail rod and an alarm circuit are installed in the nail holder, and the nail holder A perforation is formed on the top of the housing, and the aforementioned nail rod passes through the perforation and is inserted into the nail holder to act on the steel ball clamper. [0003] The steel ball clamping device includes a guide cylinder, a group of steel balls for clamping the nail rod, a push piece and a force spring for pressing the group of steel balls; the guide cylinder is a cylindrical structure with an open bottom, and ...
