Detailed Description

The following further description is made with reference to the embodiments shown in the drawings.

The code matching unlocking device of the anti-theft tag comprises an unlocking device body 1, a base 2, a lock cylinder assembly 3, an alarm assembly and a transformer 10.

The lock opener body is arranged in a cylindrical shape, wherein an aluminum shell surface 1-1 is in threaded connection with an aluminum shell bottom 1-3, and magnetic steel 1-5 for providing magnetic force is arranged inside the lock opener body; the upper end surface (namely the top surface of the aluminum shell surface) of the lock opener body is used as an unlocking surface; in order to further improve the magnetic force at the unlocking surface, the middle part of the aluminum shell surface is provided with a through hole 1-2, and a stainless steel separation sheet 1-4 is welded at the through hole for sealing.

The base comprises a cover body 2-1 and a base body 2-2 which are fixedly connected through a screw 6, wherein the cover body is provided with a containing groove 2-3 for containing and supporting the unlocking device body. During installation, the seat body can be fixed on a worktable such as a desktop through the screw 6. The unlocking device body is fixedly connected with the base through a double-core spring wire steel cable 5, and a worker can take the unlocking device body out of the base and perform moving operation within a certain range; the double-core spring wire steel cable is connected into an alarm circuit in the alarm assembly to give an alarm when the wire is broken, so that the lock opener body is prevented from being stolen by someone who shears the double-core spring wire steel cable.

The lock cylinder assembly is arranged on the base body and can be matched with the lock opener body in a clamping mode, and therefore the lock opener body is locked in the base. The lock cylinder component comprises a lock tongue 3-1, a lock hook 3-2, a button 3-3 and an elastic component 3-4. The lock tongue is driven by the keys 3-6 to move horizontally, and the tail end of the lock tongue can extend into the accommodating groove so as to lock or release the lock opener body. The lock hook is hinged in the base through a pin shaft 3-8 which is horizontally arranged so as to swing in a vertical plane; the lock hook is provided with a clamping head 3-5 extending into the containing groove and used for clamping the lock opener body to prevent the lock opener body from shaking in the containing groove. The button can be vertically and slidably positioned on the base and used for driving the locking hook to swing; the button sets up in the top of latch hook, when button vertical movement and downward application of force in the latch hook, can drive the dop and move (clockwise in fig. 3 promptly) towards the direction of keeping away from the storage tank to make the dop relax the unlocking body, make things convenient for the staff to take out the unlocking body from the storage tank. The elastic piece adopts a spring which is vertically arranged on the base (specifically in the spring holes 2-4 of the base body) and the upper part of the spring is propped against the latch hook. In addition, in the containing groove: the battery cover plate 11 is fixed with the bottom of the accommodating groove through two screws, and forms a battery box for accommodating the alarm battery with the inner wall of the bottom of the accommodating groove. The battery cover plate is upwards sequentially provided with an aluminum shell bottom 1-3 and an aluminum shell surface 1-1, and a circuit board fixing sleeve 8 is arranged in an inner cavity at the upper part of the aluminum shell bottom; the magnetic steels 1-5 are fixed in the cavity at the center of the aluminum shell surface and are pressed against the top end of the aluminum shell bottom.

The above structure is similar to CN 114482706.

For preventing the lock opener from being illegally used, the utility model discloses the improvement of making is: a code matching circuit board 9 for transmitting a code matching signal to the anti-theft tag and a voltage division circuit board 7 for providing partial voltage for the operation of the code matching circuit board are also arranged in the unlocking device body; the specific installation positions can be seen from fig. 3 and 7: because an external power supply is adopted, a battery is not needed, and the cavity in the alarm battery box is used for installing the voltage division circuit board 7. The code matching circuit board 9 is arranged on a circuit board fixing sleeve 8 in the bottom of the aluminum shell; as can be seen from fig. 7: the inner sides of the three support legs of the circuit board fixing sleeve are respectively provided with a notch 8-1, and the periphery of the code matching circuit board is clamped in the three notches. The power supply input end of the voltage division circuit board is connected with the output end of the transformer 10, and the power supply output end of the voltage division circuit board is connected with the input end of the code matching circuit board so as to provide working voltage for the code matching circuit board; the voltage division circuit board is also connected with the code matching circuit board through a lead, so that a verification signal is output to the code matching circuit board (the drawing is clear, a power supply connecting wire and a signal lead of the voltage division circuit board are omitted, and the power supply connecting wire and the signal lead of the code matching circuit board are also omitted). The corresponding matching is as follows: all the anti-theft tags are provided with receiving elements for receiving code matching signals, and if the anti-theft tags do not receive the code matching signals during unlocking, the configured alarm components can send out alarm sound signals.

Further, the output voltage of the transformer is 12V.

Further, the voltage division circuit board divides voltage according to a proportion of 5.

The utility model discloses a theory of operation is:

the transformer in the utility model converts the voltage into 12V; the voltage division circuit board divides voltage according to the proportion of 5; the design can prevent the stolen unlocking device from working (an illegal owner usually utilizes the charge pal to supply power to the unlocking device, but the 5V voltage output by the charge pal is only 3.5V after being divided by the voltage dividing circuit board according to the proportion of 5. If the voltage division circuit board cannot work, the code matching circuit board cannot receive the verification signal, and therefore the code matching signal cannot be sent out. When the anti-theft tag is physically unlocked, the code matching signal needs to be received immediately; otherwise, the label can send out an alarm signal, and the alarm can not be finished until the label receives the code matching signal.

The lock opener can not work when being stolen (if an illegal thief cuts off the steel cable, only the lock opener of the magnetic steel part is stolen, and at the moment, the lock opener can not work when an external power supply or a charger is used for charging the lock opener), thereby achieving the aim of preventing the lock opener from being stolen.
