Background

An anti-theft label belongs to the Electronic Article Surveillance (EAS) technology and is used for identifying an anti-theft soft label which is stuck on an article or an anti-theft hard label which is nailed on a clothing shoe cap and detected by a detection system which is placed at an entrance or a cash register passage of a supermarket in a shopping mall.

The existing integrated anti-theft hard tag is generally composed of a steel needle, a plastic shell and a lock cylinder. The lock core is composed of steel balls, steel rings and springs. The steel ball is normally in a closed state under the thrust of the spring, when the steel needle is inserted, the steel ball is tightly buckled in a gap of the steel needle, when the anti-theft buckle is opened, the steel ball clamping the steel needle in the lock cylinder is sucked away from the steel needle by the magnetic steel above 800GS, so that the steel needle can be smoothly pulled out of the magnetic buckle.

The anti-theft hard tag is arranged in such a way that the tag is swung forcefully corresponding to the moving direction of the steel needle, or the position of the steel ball is knocked forcefully to cause the inertia of the steel ball to be larger than the elastic force of the spring, so that unlocking is formed, the anti-theft failure is caused, and an anti-theft leak exists.

The technical problem to be solved by the invention is as follows: in order to overcome the defects of the prior art, the invention provides the conjoined anti-theft tag, which avoids the situation that the anti-theft tag is violently cracked due to mistaken unlocking of the pressing block when the pressing block is impacted or swung by a large force at the position of the pressing block, and effectively improves the reliability and the safety of the tag.

The technical scheme adopted by the invention for solving the technical problems is as follows: a conjoined anti-theft label comprises a steel needle and a shell, wherein the shell is telescopically connected with a lock cylinder, the steel needle is fixed on the lock cylinder and synchronously moves along with the lock cylinder, and an unlocking mechanism is also arranged in the shell; the unlocking mechanism comprises a pressing block, a locking spring, an elastic cap and a limiting frame, the pressing block, the locking spring, the elastic cap and the limiting frame are consistent in moving direction, the limiting frame is guided and limited to be connected to the shell, the pressing block is arranged at one end of the limiting frame and moves synchronously with the limiting frame, the other end of the limiting frame is matched and connected with the lock cylinder, the lock cylinder is controlled to be unlocked by the movement of the limiting frame, the unlocking stroke between the limiting frame and the lock cylinder is an unlocking stroke, the elastic cap is arranged on the shell in a friction mode, one end of the locking spring is fixed on the pressing block, and the other end of the locking spring points to the direction of the elastic cap; the maximum stroke of the elastic cap is the distance between the elastic cap and the limiting frame, and the maximum stroke is smaller than the unlocking stroke; the movement direction of the pressing block is different from that of the steel needle.

In the scheme, through the design that the movement direction of the pressing block is not consistent with that of the steel needle, the situation that the anti-theft label is cracked in violent modes such as knocking and swinging along the movement direction of the steel needle can be effectively avoided. Simultaneously, the elasticity cap has been designed in the direction is inhaled to magnetism, because elasticity cap itself has elasticity, can take place deformation when it is knocked, has effectively cushioned and has knocked, has rationally designed the biggest stroke of elasticity cap simultaneously, even overcome the deformation of elasticity cap and knock the elasticity cap and make it move to the end for the shell, even elasticity cap and unblock spring contact extrusion, only can support the spacing frame more on the lock core, only can lock closely, and can not take place the unblock.

In order to reduce the influence of violent stress on the unlocking mechanism in the moving direction of the steel needle, the moving direction of the steel needle is perpendicular to the moving direction of the pressing block.

Preferably, in order to move the spacing frame and carry out reasonable spacing, make its effectual motion of stabilizing, realize locking and unblock operation, the shell in have the spout that corresponds spacing frame moving direction and set up, spacing frame slide and set up in the spout.

Furthermore, the lock between the limiting frame and the lock cylinder is realized by the limiting locking of the limiting frame after the lock cylinder crosses the limiting frame by the contact surface contact and pressing down the limiting frame, and the unlocking of the limiting frame and the lock cylinder is realized by the self-help pressing down of the limiting frame so that the lock cylinder and the limiting frame are unlocked and can return. The lock core is also provided with a pressing locking part which is matched with the contact surface to press down the limiting frame when the driving steel needle moves and is fixed by the limiting frame after the driving steel needle passes the limiting frame in a limiting way, the contact surface is an inclined surface, and one side of the pressing locking part, which is correspondingly opposite to the contact surface, is also provided with an inclined surface.

Furthermore, the lock core can be further designed, so that the lock core can effectively prevent burglary and prevent a steel needle from scratching workers in use, and meanwhile, the effect of assisting in popping out the outer sleeve to realize final unlocking in unlocking is achieved through the design of the outer unlocking spring. The lock core include outer sleeve and inner skleeve, the inner skleeve tail end slide spacing connection in the outer sleeve, the front end then stretches out the outer sleeve front end, elasticity crimping has interior protection spring between inner skleeve and the outer sleeve, the steel needle fix in the outer sleeve and outer tip stretches out the outer sleeve, the minimum stroke of resilience of interior protection spring for outwards ejecting the inner skleeve to steel needle outer tip parallel and level, push down locking portion set up on the outer sleeve outer peripheral face.
