Problems solved by technology

[0002] Expansion nails are widely used in daily life, but at present, expansion nails are generally only used to fix or fasten objects. At present, expansion nails are also used for fastening on the outer packaging of some products, but expansion nails are only used for fastening The function does not have anti-counterfeiting function, and because of counterfeiting or counterfeiting of some more expensive commodities such as alcohol and artwork, merchants usually set anti-counterfeiting marks on the outer packaging. Those who recycle the original outer packaging for reuse, this anti-counterfeiting method will not have any effect, and consumers will not be able to distinguish it at all. If an anti-counterfeiting structure is installed on the locking mechanism of the outer packaging, it is undoubtedly good to cooperate with the current conventional anti-counterfeiting methods.

Embodiment Construction

[0014] like Figure 1-4 As shown, an anti-counterfeiting expansion nail includes an expansion nail 1 and an expansion sleeve 2. The expansion sleeve 2 is provided with an expansion hole 21 inside. The bottom of the expansion sleeve is made into a petal shape towards the groove 22. The expansion nail 1 includes a pin 11 and a nail cap. The nail cap is composed of left and right nail caps 12, 13, and the left and right nail caps 12, 13 are mutually Hinged, the lower end of the pin 11 is provided with a self-locking head 14, the self-locking head 14 presents an inverted round platform, and a circle of ribs 141 is naturally formed at the junction of the upper part of the inverted round platform and the pin, and the upper part of the pin 11 is limited. The rotation part 15, the rotation limiting part 15 is connected as a whole with the right nail cap 13 through an easy-to-break rib 3, and the upper part of the expansion sleeve 2 is provided with a rotation limiting hole 23 correspo...

Abstract

The invention relates to an anti-counterfeiting expandable nail which comprises an expandable nail and an expandable sleeve, wherein an expandable hole is arranged in the expandable sleeve; the lower part of the expandable hole is in a taper shape; and the wall of the lower part of the expandable hole is provided with an axial groove, so that the lower part of the expandable sleeve is in a petaloid shape. The invention is characterized in that the expandable nail comprises a pin and a nail cap, wherein the lower end of the pin is provided with a self-locking head; the upper part of the pin is provided with a rotation limit part; the rotation limit part is connected with the nail cap to form an integral body through a breakable rib; and the upper part of the expandable sleeve is provided with a rotation limit hole corresponding to the rotation limit part. The invention adopts the anti-counterfeiting structure that the expandable nail is required to be destroyed when the user opens the package locked by the expandable nail; and after the expandable nail is destroyed, the main body can be permanently retained on the package, thereby having favorable anti-counterfeiting function.
