Description

Technical Field

[0001] The invention relates to an anti-theft device, in particular to a lock core structure for hooking an anti-theft tag. Background Art

[0002] Hanging display sales is a commodity sales method widely used in shopping malls and supermarkets. Hanging display can make non-three-dimensional commodities produce a good three-dimensional effect, and can add changes that other special display methods do not have. At present, many enterprises produce commodities with hanging display holes, such as candy, razors, pencils, toys, small hardware tools, headwear, socks, batteries, etc. These commodities are all packaged in sheet-shaped plastic packaging boxes, and are inserted on the hooks of the shelves through the openings on the packaging boxes for consumers to choose. In addition, some higher-value commodities have also been added to the hanging display. Commodities sold in this way also need to use anti-theft tags, so the lock core structure used in the anti-theft tags is the key. Summary of the invention

[0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the above-mentioned background technology and provide a novel lock core structure for hooking an anti-theft tag, which should have an anti-theft function and be easy to use.

[0004] The technical solution provided by the present invention is:

[0005] A new lock core structure for a hook anti-theft tag includes a bottom shell and a front shell that are hingedly connected to form a cover seat; the characteristic is that the lock core structure also includes a locking assembly installed in the inner cavity of the cover seat to lock the bottom shell and the front shell into one, and an unlocking component that can open the locking assembly under the action of a magnetic unlocker; a columnar hook that can hook a sheet-like packaging box is made between the bottom shell and the front shell.

[0006] The locking assembly includes a bottom cover fixed to the inner side of the bottom shell and having two columnar hooks, a surface cover fixed to the inner side of the surface shell to form a cavity, and a locking strip that can be laterally movably embedded in the cavity to interact with the columnar hooks through a locking structure.

[0007] The locking structure includes: a groove made in the middle part of the columnar hook and extending along the busbar direction, an opening opened on the surface cover corresponding to the columnar hook and facilitating the insertion of the columnar hook, and a lock head made on the lock strip and capable of being inserted and matched with the groove.

[0008] The unlocking component includes a steel ball movably embedded between the face cover and the lock bar, and an inclined surface obliquely made on the lock bar and capable of interacting with the steel ball, so that the steel ball can exert a lateral pushing force on the lock bar when it moves; the moving route of the steel ball is perpendicular to the moving direction of the lock bar.

[0009] A lock core spring is also installed between the lock bar and the face cover, and the lock core spring can apply force to the lock bar to make the lock head fit into the groove.

[0010] The unlocking component also includes an auxiliary spring, which applies force to the steel ball to enable it to move toward the bottom cover.

[0011] The working principle of the present invention is (see Figure 7 ):

[0012] After the acoustic magnetic coil or magnetic bar coil and RFID are installed in the present invention, it becomes an anti-theft tag. When in use, the bottom shell connected to the bottom cover and the surface shell connected to the surface cover swing around the hinge axis to open like a clam shell, and the plastic packaging box ( Figure 7 The opening on the plastic packaging box (with the item in the middle) is inserted into the two columnar hooks, and then the top shell and the bottom shell are closed, so that the two locks in the locking assembly are embedded in the grooves of the columnar hooks with a "snap", thereby locking the plastic-sealed packaging box on the anti-theft label.

[0013] If someone steals a plastic-sealed box in a shopping mall without permission, the acoustic magnetic coil in the anti-theft tag will trigger the antenna when passing by the antenna at the mall entrance, and the antenna will then sound and light alarms.

[0014] When unlocking, just align the magnetic unlocker with the unlocking part of the face shell. The steel ball will be attracted by the magnetic force and push the lock bar to move horizontally during the movement, so that the lock head on the lock bar will exit the groove of the columnar hook. The face shell will then open from the bottom shell, and the columnar hook will also detach from the face cover, and the plastic-sealed packaging box can be removed from the columnar hook.

[0015] The beneficial effects of the present invention are as follows: due to the unique anti-theft structural design on the lock core, the formed anti-theft label has perfect anti-theft performance, ensuring the safety of the goods displayed for sale in a hanging manner, and also enabling the displayed goods to be placed properly (without tilting), thereby obtaining a good display effect. In addition, the present invention is convenient to use and is welcomed by users. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following is a further description with reference to the embodiments shown in the accompanying drawings.

[0024] Figures 1 to 3 The lock core structure of the new hook anti-theft tag shown includes a cover seat with a curved hook 1, in which an acoustic magnetic coil or a magnetic bar coil and an RFID (the acoustic magnetic coil or the magnetic bar coil and the RFID are omitted in the figure) can be installed; this is similar to the lock core structure of the existing anti-theft tag.

[0025] The improvement of the present invention is that: in the cover seat: the bottom shell 7 and the surface shell 9 are connected by a hinge pin 6 (by Figure 1 It can be seen that the hinge pin is arranged horizontally on the top of the cover seat) and can be hinged and connected as a whole. The locking assembly is installed in the inner cavity of the cover seat to lock the bottom shell and the front shell as a whole. The unlocking component can open the locking assembly under the action of the magnetic unlocker, thereby opening the cover seat (similar to the opening of a clam shell). A columnar hook that can hook a sheet-shaped packaging box is also made between the bottom shell and the front shell; it can be seen from the figure that the axis of the columnar hook is basically perpendicular to the axis of the hinge pin.

[0026] In the locking assembly: the bottom cover 5 with two columnar hooks 10 is fixed (preferably fixed by adhesive) on the inner side of the bottom shell; the surface cover 8 is fixed (preferably fixed by adhesive) on the inner side of the surface shell, thereby forming a cavity between the surface shell and the surface shell; the locking strip 3 can be laterally movably embedded in the cavity, thereby interacting with the columnar hooks through the locking structure.

[0027] In the locking structure: a groove 10.1 is made in the middle of the columnar hook (the top of the columnar hook remains cylindrical to prevent the groove from extending upward), and the groove extends downward along the busbar direction; openings corresponding to the two columnar hooks are opened on the surface cover to facilitate the columnar hooks to enter the cavity through the openings and extend into the position corresponding to the lock head 3.1 in the middle of the lock bar; a guide rail 8.1 is made on the inner side of the surface cover, and the lock bar can be movably inserted into the guide rail, so that the lock head on the lock bar can be inserted and matched with the groove on the columnar hook one by one. A lock core spring 4 is also installed between the lock bar and the surface cover; Figure 1It can be seen that the left end of the lock core spring is sleeved on the convex head 3.2 of the lock bar, and the right end of the lock core spring is against the slot 8.1.1 on the left side of the guide rail; therefore, the lock core spring can exert a leftward thrust on the lock bar, so that after the lock bar moves to the left, the lock head is inserted and matched with the groove. After the lock head is inserted into the groove, the cylindrical top of the columnar hook can prevent the lock head from sliding outward along the generatrix direction; thus effectively preventing the opening swing of the front shell and the bottom shell around the axis of the hinge pin (opening and swinging like a clam shell).

[0028] In the unlocking component: the steel ball 2 is movably embedded between the cover and the lock bar (by Figure 2 , Figure 6 It can be seen that: the inner side of the cover is provided with a circular sliding groove 8-2, in which a steel ball is placed and can slide along the axis of the sliding groove (the sliding direction of the steel ball is perpendicular to the moving direction of the lock bar); a fork is provided on the right side of the sliding groove to pass through the generatrix direction, and the inclined surface 3.3 obliquely made on the lock bar can be slidably inserted into the fork accordingly, so that a space with a small top and a large bottom is formed in the sliding groove (see Figure 2 ). When the steel ball moves upward under the action of external magnetic force, it will exert force on the inclined surface and force the lock bar to move to the right, thereby driving the lock head to leave the groove and realize the unlocking operation.

[0029] Furthermore, as embodiment 2, the unlocking component further includes an auxiliary spring 11, which is positioned in the sliding groove and always applies force to the steel ball to enable it to move toward the bottom cover, thereby ensuring that the steel ball moves accurately. Since the elastic force of the auxiliary spring is relatively small, it has almost no effect on the unlocking of the steel ball.
