Abstract
Description
Technical Field
[0001] The utility model relates to a novel anti-theft tag lock core. Background Art
[0002] The anti-theft tag is a common commercial anti-theft device. Its lock core is the core component to realize the anti-theft function. It is closed by the principle of magnetic adsorption, so that the anti-theft tag can be stably fixed on the product, thereby realizing identification and anti-theft. When unlocking the existing anti-theft tag lock core, it is only necessary to place a strong magnet on one side of the lock core. The iron cup and iron ball in the lock core are attracted by the magnetic force and release the lock pin to achieve unlocking. However, the anti-theft effect of this anti-theft tag lock core is limited. The thief only needs to prepare a strong magnet in advance to easily remove the anti-theft tag from the product. Therefore, it is necessary to develop a new type of anti-theft tag lock core to solve the above problems. Utility Model Content

[0016] See Figures 1 to 3 A new anti-theft tag lock core shown in the figure includes a shell 11, a shell cover 12 is provided on the top of the shell 11, a through hole 15 is provided on the bottom of the shell 11, an iron cup 13 is provided in the shell 11, a through hole 2 16 is provided at the bottom of the iron cup 13, an iron ball 14 and a partition 17 are provided in the iron cup 13, there are three iron balls 14, one side of each iron ball 14 is provided with a movable hole 20, the movable hole 20 is provided on the side wall of the iron cup 13, the partition 17 is provided on the upper side of the iron ball 14, a spring 18 is provided between the partition 17 and the shell cover 12, an installation cavity 21 is provided at the bottom of the partition 17, a buzzer 24 and a radio frequency coil 25 are provided in the installation cavity 21, a button 23 is provided on the top of the partition 17, a column 19 is provided on the upper side of the button 23, and the column 19 is fixed on the top wall inside the shell cover 12; each iron ball 14 passes through the movable hole 20 and abuts against the inner wall of the shell 11.
[0017] Furthermore, a cover plate 22 is provided on one side of the RF coil 25 , and the cover plate 22 is connected to the bottom wall of the partition plate 17 by bolts.
[0018] Furthermore, the lower part of the shell 11 is in a truncated cone shape, and the iron ball 14 abuts against the inclined inner wall of the lower part of the shell 11; when the iron cup 13 and the iron ball 14 are attracted by the strong magnet and move upward, the iron ball 14 no longer abuts against the inclined inner wall of the shell 11, and the three iron balls 14 become loose, and the locking pin sandwiched between the three iron balls 14 will be loosened.
[0019] Furthermore, matching threads are provided on the outer wall of the upper portion of the shell 11 and the inner wall of the shell cover 12; the shell 11 and the shell cover 12 are threadedly connected, and the interior of the shell 11 can be sealed by tightening the shell cover 12. The spring 18 between the shell cover 12 and the partition 17 is in a compressed state at this time.
[0020] Furthermore, the through hole 15 and the through hole 2 16 are located on the same vertical line, and the apertures of the through hole 15 and the through hole 2 16 are the same; the through hole 15 and the through hole 2 16 are located on the same straight line and aligned with the gaps between the three iron beads 14 , and the locking needle can be inserted into the gaps between the three iron beads 14 by passing through the through hole 15 and the through hole 2 16 , so that the locking needle is clamped by the three iron beads 14 .
[0021] The working principle of the present invention is that when the anti-theft tag is used, the lock core is installed in the shell of the tag, and the lock pin passes through the through hole 15 and the through hole 2 16 and extends between the three iron beads 14, so that the lock pin is clamped by the three iron beads 14. When unlocking, the user uses a strong magnet to attract the iron cup 13 and the iron beads 14, and uses the radio frequency transmitter to transmit a signal to the radio frequency coil 25. The iron cup 13 and the iron beads 14 move upward under the attraction of the strong magnet, and the iron beads 14 no longer press against the inclined inner wall of the shell 11. The three iron beads 14 become loose, and the lock pin sandwiched between the three iron beads 14 will be released. In this process, the radio frequency coil 25 receives a specific signal from the radio frequency transmitter. The signal is sent to the buzzer 24, causing the power to be cut off, and the iron cup 13 moves up, causing the partition 17 and the button 23 to move up, until the column 19 abuts against the button 23. The button 23 is pressed by the column 19 to activate the buzzer 24, but the buzzer 24 is powered off at this time, so the buzzer 24 will not sound an alarm, and the user can take away the lock pin normally; when the thief uses a strong magnet to unlock the lock cylinder, because the thief does not have a radio frequency transmitter and does not know the specific signal frequency set by the user, the thief uses a strong magnet to attract the iron cup 13 and the iron ball 14, and the buzzer 24 will not be powered off. After the button 23 is pressed by the column 19, the buzzer 24 is activated, and the buzzer 24 sounds an alarm to remind someone of theft.
[0022] The above are only specific embodiments of the present invention, but the scope of protection of the present invention is not limited to them. Any changes or substitutions that do not require creative work should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection defined in the claims.
