Detailed implementation manners

[0033] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0034] As Figure 1 shown, the multifunctional protection bag label includes a clamping seat 1, a tongue depressor 2, a rotating plate 3, a lock core structure, and an anti-theft circuit.

[0035] The tongue depressor is rotatably positioned on the clamping seat, and a clamping opening A is formed between the clamping seat and the tongue depressor for clamping the protection bag. The rotating plate is rotatably positioned on the clamping seat, and the rotating plate is used to drive the tongue depressor to move so that the clamping opening is closed. The lock core structure is used to lock the rotating plate so that the clamping opening remains in a closed state. The anti-theft circuit is used for alarm monitoring.

[0036] As Figure 9 , Figure 10 shown, the clamping seat is provided with a locking port 1-1, a supporting platform 1-3, and a locking groove 1-4. As Figure 7As shown in the figure, the supporting platform is arranged at the right end of the clamping seat, the tongue depressor is located above the supporting platform, and the clamping opening is formed between the supporting platform and the tongue depressor. The clamping seat is also provided with a fitting groove, and the RFID tag 6 or the NAL tag 7 is installed in the fitting groove, and the bottom cover 1-5 closes the fitting groove. A hook 5 is rotatably hinged on the clamping seat, which is convenient for the tag to be hung on the hook or iron rod in the supermarket.

[0037] As Figure 12 shown in the figure, the rotating plate is rotatably positioned on the clamping seat through the second rotating shaft 22. The rotating plate is provided with a cam 3-1, a locking hook 3-2, and a through hole 3-3. The rotating plate is a lever structure (one end of the locking hook is the power arm, and one end of the cam is the resistance arm, and the power arm is greater than the resistance arm). The cam is located at the rotation center of the rotating plate, and the locking hook is far from the rotation center of the rotating plate. When locking, the locking hook can apply a strong lever force and a pre-tightening force to squeeze the tongue depressor against the cam, so as to tightly clamp the protection bag.

[0038] The cam is used to squeeze the tongue depressor to close the clamping opening, and the rotation axis of the cam is the axis of the connecting shaft. When the rotating plate rotates, the cam also rotates synchronously. The cam applies a thrust to the tongue depressor through the change of the curved surface, so that the tongue depressor approaches the clamping seat.

[0039] The locking hook is arranged at the distal end of the rotating plate ( Figure 8 the left end of), when the locking hook is inserted into the locking opening, the lock core structure catches the locking hook to complete the locking. At this time, the rotating plate is closely attached to the surface of the clamping seat. The rotating plate has a certain elasticity. When the clamping opening clamps products of different thicknesses, the bending of the rotating plate ensures that the locking hook is inserted into the locking opening and is caught by the lock core structure to complete the locking.

[0040] The lock core structure includes a spring 31, a stud 32, and a lock cap 33. As Figure 7 shown in the figure, the stud can slide horizontally along the lock groove. The lock cap is installed at the left end of the clamping seat. The spring is located between the lock cap and the stud. The right end of the lock groove communicates with the locking opening. The stud extends into the locking opening under the push of the spring. The locking hook is provided with a through hole 3-3 for the stud to penetrate.

[0041] As Figure 7 shown in the figure, rotate the rotating plate counterclockwise to lock. The locking hook is inserted into the locking opening. The locking hook first pushes the stud (the stud moves horizontally to the left). When the locking hook is inserted in place, the stud rebounds (the stud moves horizontally to the right) and extends into the through hole to catch the locking hook to complete the locking.

[0042] A knock-proof structure is provided between the stud and the locking hook. In the knock-proof structure, the through hole is a stepped hole, and the stud is a stepped shaft. The stepped surface of the stepped hole and the stepped surface of the stepped hole are buckled with each other, so that the locking hook also catches the stud, preventing the stud from retracting into the lock groove and avoiding accidental unlocking caused by the loosening of the stud due to external force knocking.

[0043] The tongue depressor is rotatably positioned on the clip seat through the first rotating shaft 21. A torsion spring 23 is provided on the first connecting shaft. The first connecting shaft passes through the spiral part of the torsion spring, and the two ends of the torsion spring respectively abut against the clip seat and the tongue depressor. When unlocking, the tongue depressor is pushed upward by the torsion spring, and the clip opening is automatically opened. When locking, the clip opening is closed, and the bottom surface of the tongue depressor closely adheres to the top surface of the support table.

[0044] The anti-theft circuit includes a circuit board assembly 11, a break switch 12, a power-on switch 13, and a coil 14. The circuit board assembly includes a bracket 15, a circuit board 16, and a battery 17. The circuit board is fixed in the clip seat through the bracket, and the battery is installed in the bracket to supply power to the circuit board. A battery cover 18 is provided on the bracket. An opening for cooperating with the lock groove is provided on the bracket.

[0045] The circuit board is provided with a buzzer 16-1 and an indicator light 16-2. The bracket is installed on the top of the clip seat, and the top surface of the bracket also serves as the top surface of the clip seat. The indicator light extends out of the top surface of the bracket. When locking, the rotating plate completely blocks the bracket. Therefore, sound holes 3-5 and light holes 3-4 for cooperating with the buzzer and the indicator light are provided on the rotating plate.

[0046] The circuit board is electrically connected to the break switch, the power-on switch, and the coil. The circuit board is electrically connected to the break switch and the coil through wires. The coil is installed in the clip seat, and the coil is 8.2m or 58k. The power-on switch is installed on the circuit board, and a switch cap 16-3 for cooperating with the contact of the power-on switch is provided on the bracket. When locking, the rotating plate presses the switch cap of the bracket to turn on the power-on switch, and the alarm monitoring is turned on. When unlocking, the rotating plate opens, the switch cap is loosened, the power-on switch is turned off, and the alarm monitoring is turned off.

[0047] The break switch is installed in the clip opening. As Figure 11 shown, the break switch is installed on the tongue depressor. The tongue depressor is provided with a switch groove 2-1, and the contact of the break switch passes through the switch groove and extends into the clip opening. As Figure 7 shown, a concave platform 1-2 for cooperating with the break switch is provided on the clamping surface of the support table, and the concave platform is lower than the clamping surface of the support table. When the clip opening is closed and the protection bag is clamped, the contact abuts against the protection bag, and the break switch is turned on. If the protection bag is forcefully pulled out, the contact pops out and extends into the concave platform, and the break switch is turned off.

[0048] The bottom surface of the tongue depressor is the upper clamping surface of the clip opening. The top surface of the support table is the lower clamping surface of the clip opening. Metal abrasive plates 4 are provided on the clamping surfaces of the support table and the tongue depressor. The metal abrasive plates are fixedly bonded to the two clamping surfaces through double-sided adhesive tapes. The metal abrasive plates are made by an etching process. Notches for avoiding the break switch are provided on both metal abrasive plates.

[0049] The working principle of the present utility model is:

[0050] 1. Locking

[0051] Put the protection bag into the clamping opening, press the turning plate counterclockwise ( Figure 7 in the counterclockwise direction), so that the locking hook is inserted into the locking opening to complete locking. The cam of the turning plate squeezes the tongue plate to tightly clamp the protection bag by the clamping opening, and the protection clip and the protection bag are integrated; the metal frosted plate can greatly improve the friction force and increase the difficulty of forcibly pulling out the protection bag;

[0052] 2. Unlocking

[0053] Bring the magnetic unlocking device close to the lock core structure, press the turning plate by hand to separate the two step surfaces of the stud and the locking hook. The stud automatically disengages from the locking opening under the magnetic force. After releasing the hand, the torsion spring drives the tongue plate to rotate counterclockwise ( Figure 7 in the counterclockwise direction), the clamping opening automatically opens and the locking hook automatically pops out of the locking opening, and the protection clip and the protection bag are separated;

[0054] 3. Anti-theft protection

[0055] When locking, the open circuit switch is closed, the power-on switch is closed, the circuit board is powered on, and enters the anti-theft monitoring state;

[0056] If locking is performed without putting the protection bag, the open circuit switch remains open, the circuit board is not powered on, and will not enter the anti-theft monitoring state;

[0057] If the protection bag is forcibly pulled and withdrawn from the clamping opening, the open circuit switch is disconnected, and the label itself emits an alarm;

[0058] If the goods are carried through the goods exit without removing the label, the antenna at the exit position will trigger an alarm, and the label itself also emits an alarm;

[0059] If the label is forcibly knocked, the anti-knock structure can prevent the core structure from being accidentally unlocked;

[0060] 4. Maintenance

[0061] The label is built-in with an RFID label or a NAL label, which is convenient for customers to count goods and saves labor costs.

[0062] Only when the turning plate is turned up during unlocking can the battery be replaced.

[0063] The preferred embodiments of the present invention are shown in the accompanying drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described in this specification. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.
