Description

The market anti-theft tag

Technical field

The utility model relates to a kind of anti-theft device, especially is used for antitheft label in the market.

Background technology

Conventional at present market comprises the head of a nail and the clamping body that can fixedly connected with the head of a nail with anti-theft tag; The nail bar that the described head of a nail comprises cap and is fixed on cap central authorities and overhangs outstanding; Described clamping body comprises housing, be positioned the warning circuit of housing and be installed on the lock core of housing central authorities, and the perforation that described nail bar passes the clamping body top is inserted in the housing and cooperated with lock core.

Described lock core comprises the tubular positioning seat that a lower end is uncovered, positioning seat is built-in with an arc pawl seat, this arc pawl seat upper end is equipped with the steel ball that is used for the locking nail bar, there is the spring of installation the lower end of arc pawl seat, thereby so that the inner peripheral surface effect of each steel ball and positioning seat locking is inserted in the middle nail bar of arc pawl seat.

This kind device has antitheft effect, but the arc pawl seat in the lock core is a metal material, and cost is higher, and weight is big, in use the easy damaged commodity; And the nail bar the nail point be the tip shape, to clothing particularly the silk like clothing have damage.

The utility model content

Technical problem to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of improvement of anti-theft device is provided, and this market should have with anti-theft tag that anti-theft feature is strong, simple in structure, cost is lower and to clothing damage features of smaller.

The technical solution adopted in the utility model is: the market anti-theft tag comprises the head of a nail and the clamping body that can fixedly connected with the head of a nail; The nail bar that the described head of a nail comprises cap and is fixed on cap central authorities and overhangs outstanding; Described clamping body comprises housing, be positioned the warning circuit of housing and be installed on the lock core of housing central authorities, the perforation that described nail bar passes the clamping body top is inserted in the housing and is cooperated with lock core, and it is characterized in that: the arc pawl seat employing plastic material in the described lock core is made.

The nail point of described nail bar is the round end shape.

Use-pattern of the present utility model is: the nail bar of the head of a nail is passed sheet object (as the lining of clothes, label or the like) insert clamping body again, the nail bar passes the centre that penetrates and be positioned at each steel ball of arc pawl seat behind the through hole of perforation, positioning seat on clamping body top more successively.Arc pawl seat up moves under the effect of spring force, the outer circumference surface of each steel ball be subjected to positioning seat internal conical surface contention effect and compress jointly toward nail rod axis direction, thereby each steel ball is nibbled firmly follows closely the outer circumference surface of bar; When the people attempts the drawing head of a nail, because the particular angular relationships of the internal conical surface of positioning seat can't pull away it thereby the strength of nibbling instead can strengthen the locking nail bar.As want release only to need with the spring terminal of the close market of a release magnetic patch with anti-theft tag, and spring is spurred and drives arc pawl seat and moves down by magnetic force, and each steel ball is eliminated the acting force of nibbling of nail bar thereupon, and the nail bar can successfully be extracted.

The beneficial effects of the utility model are: simple in structure, locking effect is good, and anti-theft feature is stronger; Arc pawl seat in the lock core adopts plastic material to make, and cost of manufacture is lower; And the nail point of nail bar is the round end shape, clothing damaged less, thereby market outlook are wide.

Embodiment

As shown in the figure, the market anti-theft tag comprises the head of a nail and the clamping body of fixedlying connected with the head of a nail; The nail bar 2 that the described head of a nail comprises cap 1 and is fixed on cap central authorities and overhangs outstanding; Described clamping body comprises housing 4 (housing upper end by cover plate 3 bonding covering), be positioned the warning circuit 9 (prior art) of housing and be installed on the lock core of housing central authorities, and the perforation 3-1 that described nail bar passes the clamping body top inserts that housing is interior to be cooperated with lock core.

Described lock core comprises the tubular positioning seat 5 that a lower end is uncovered, and the inner peripheral surface of positioning seat is the big down little internal conical surface of, and the top of positioning seat is shaped on through hole 5-1 and this hole is aimed at described perforation 3-1; Positioning seat is built-in with an arc pawl seat 6, this arc pawl seat upper end be shaped on three be distributed in circumferencial direction nibble pawl 6-1, respectively nibble pawl and all overhang toward the top from arc pawl seat, described nibbling is equipped with the steel ball 7 that is used for the locking nail bar between the pawl; There is the spring 8 of installation the lower end of arc pawl seat, thereby so that the inner peripheral surface effect of each steel ball and positioning seat locking is inserted in the middle nail bar of arc pawl seat.

Improvement part of the present utility model is: the arc pawl seat in the lock core adopts plastic material to make, and has not only effectively reduced the weight of product, and makes simple (but injection moulding one-shot forming) especially, is fit to produce in enormous quantities, significantly reduces cost; The nail point of nail bar is made the round end shape, has effectively reduced the particularly damage of silk like clothing of clothing.
