Description

Technical Field

[0001] This utility model relates to an anti-theft device, specifically an automatic retractable eight-claw anti-theft tag. Background Technology

[0002] Existing octagonal anti-theft tags (such as ZL201020637002.9 and ZL202121069151.4) include a top cover, a bottom cover, and a steel wire rope. The top cover is equipped with a rotating disc and a one-way rotation mechanism. Rotating the rotating cover can tighten the steel wire rope, so that the top cover and the bottom cover clamp the two ends of the milk powder can.

[0003] The drawback of the above structure is that:

[0004] 1. When the lock is open, the bottom needs to be pulled open to pull the steel wire out from the top cover. The top cover is equipped with a coil spring to tighten the steel wire rope. If the operator is not skilled, the bottom may be released before the goods are placed in place, and the steel wire rope will automatically retract into the top cover, causing the top cover and bottom to close together, which increases the difficulty of installing the goods.

[0005] 2. The battery holder and winding spool inside the top cover are an integrated structure, which is complicated in terms of assembly process. It requires soldering the positive and negative terminals of the battery to the circuit board through lead wires, resulting in low production efficiency and high cost. Utility Model Content

[0006] The purpose of this utility model is to overcome the shortcomings in the above-mentioned background technology and provide an automatic retractable eight-claw anti-theft tag. This anti-theft tag should be easy to operate, simple to produce, and low in cost.

[0007] The technical solution of this utility model is:

[0008] An automatic retractable eight-pronged anti-theft tag includes a top cover and a base connected by a locking cord; the top cover includes a housing, a rotating component rotatably positioned within the housing, a one-way rotation mechanism restricting the rotation direction of the rotating component, a coil spring for retracting the locking cord by the rotating component, and a circuit board electrically connected to the locking cord; characterized in that it further includes an emergency stop mechanism for preventing the rotating component from automatically retracting the cord; the emergency stop mechanism includes a pawl disposed on the rotating component, a button pressably positioned on the side of the housing for locking the pawl, and a torsion spring for resetting the button.

[0009] The outer casing includes a vertical toothed cover, a main casing, and a lower cover; the main casing has a mounting port on its side, and the button can be oscillatingly positioned in the mounting port, with a torsion spring disposed between the button and the main casing.

[0010] The end of the button is provided with a limiting bevel that mates with the edge of the mounting port.

[0011] The rotating component includes a horn cover, a winding reel, and a battery holder; the pawl is disposed on the outer circumferential surface of the battery holder; the pawl has a locking slot that engages with the button.

[0012] The circuit board is fixed to the top of the winding spool; the bottom of the battery holder is provided with a battery compartment and a battery cover; the battery is installed in the battery compartment and supplies power to the circuit board through the positive and negative springs in the winding spool.

[0013] The winding spool has a positive electrode hole and a negative electrode hole; the positive electrode spring is installed in the positive electrode hole; the negative electrode spring is installed in the negative electrode hole.

[0014] The negative electrode hole is a tapered hole that is larger at the top and smaller at the bottom, and the negative electrode spring is a tapered spring that is larger at the top and smaller at the bottom; the top of the negative electrode spring presses against the bottom surface of the circuit board, and the bottom of the negative electrode spring extends into the battery holder and presses against the negative electrode of the battery.

[0037] To make the objectives, technical solutions, and advantages of this 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 merely for explaining the present utility model and are not intended to limit the present utility model.

[0038] like Figure 1 As shown, the automatic retractable eight-pronged anti-theft tag includes a top cover 1, a base 2, and a locking cord 3 connecting the top cover and the base. The top cover includes a housing 4, a rotating component 5, a one-way rotation mechanism 6, a coil spring 7, and a circuit board 8.

[0039] The rotating component is rotatably positioned within the housing. The locking rope is wound around the rotating component and electrically connected to the circuit board. The locking rope also repeatedly passes through the top cover and the base. A coil spring is disposed between the housing and the rotating component, and the coil spring is used to drive the rotating component to rotate in order to wind up the locking rope.

[0040] The one-way rotation mechanism includes a lock cylinder head 31, a lock cylinder spring 32, a lock cylinder cap 33, a long connecting rod 34, a long connecting rod spring 35, a connector 36, a toothed connecting rod 37, a toothed connecting rod spring 38, and a toothed ring located on the inner ring of the top cover.

[0041] like Figure 16 As shown, in use, press the long connecting rod to lock, then rotate the rotating part to retract the locking rope, causing the top cover and base to clamp both ends of item A. Unlocking is only possible by using a magnetic unlocking device to open the lock cylinder. When the locking rope is cut or severed, the circuit board's electrical circuit changes, triggering an alarm. When carrying the protected item out of the designated area, the coil cannot be detected by the detection device, triggering another alarm. To unlock, the long connecting rod pops out, and the rotating part automatically retracts the locking rope under the action of a coil spring.

[0042] Additionally, coils and RFID tags are installed in the top cover or base.

[0043] The above structure is the same as that of the prior art. The improvement of this utility model is as follows:

[0044] It also includes an emergency stop mechanism, which is used to prevent the rotating parts from automatically retracting the wire.

[0045] The emergency stop mechanism includes a pawl 9, a button 10, and a torsion spring 11. The pawl is located on the outer circumference of the rotating component, the button is pressably positioned on the side of the housing, and the torsion spring 11 is used to reset the button. When the button is pressed, the button moves towards the rotating component and locks the pawl, thus preventing the coil spring from driving the rotating component to rotate for wire winding; when the button is released, the torsion spring pushes the button outward to complete the reset, and the rotating component is no longer blocked by the pawl, thus continuing to rotate for wire winding.

[0046] The outer casing includes a toothed cover 12, a main casing 13, and a lower cover 14. For example... Figure 3 As shown, the vertical tooth cover, main shell, and lower cover are arranged in sequence from top to bottom.

[0047] The main housing has a mounting port 13-1 on its side. The button can be oscillatingly positioned in the mounting port. One end of the button can be oscillatingly positioned in the mounting port via a pin 19. The other end of the button has a limiting inclined surface 10-1 that mates with the edge of the mounting port. A torsion spring is mounted on the pin.

[0048] The rotating component includes a horn cover 15, a winding reel 16, and a battery holder 17. For example... Figure 3 As shown, the speaker cover, winding reel, and battery holder are arranged sequentially from top to bottom. The pawl is located on the outer circumference of the battery holder, and the pawl has a locking slot 9-1 that engages with the button.

[0049] When the button is pressed, the limiting bevel of the button can be inserted into the pawl's slot, preventing the rotating part from rotating and automatically retracting the wire. When the button is released, the torsion spring resets the button, the limiting bevel of the button slides out of the pawl's slot, the side of the button extends out of the mounting port, the limiting bevel of the button abuts against the edge of the mounting port, and the rotating part continues to automatically retract the wire.

[0050] The winding spool and battery holder are connected vertically by fasteners (not a traditional integrated structure). The circuit board is fixed to the top of the winding spool. The bottom of the battery holder has a battery compartment 17-1, in which the battery 18 is installed and supplies power to the circuit board through a positive spring 21 and a negative spring 22. A battery cover 17-2 is disposed on the bottom of the battery compartment. The battery is a button cell, preferably a 2032 or 2450 cell.

[0051] The positive and negative springs are disposed in the winding spool. The winding spool has a positive hole 16-1 and a negative hole 16-2, both of which penetrate the upper and lower end faces of the winding spool. The positive spring is installed in the positive hole, and the negative spring is installed in the negative hole. The negative hole is a tapered hole that is larger at the top and smaller at the bottom, and the negative spring is a tapered spring that is larger at the top and smaller at the bottom.

[0052] The top of the negative spring presses against the bottom surface of the circuit board. The top surface of the battery holder is provided with a negative insertion port 17-3. The bottom end of the negative spring extends into the battery holder through the negative insertion port and presses against the negative terminal of the battery. This structure can limit the negative spring and prevent it from sliding outward during assembly.

[0053] The top of the positive spring presses against the bottom of the circuit board. The bottom of the positive spring is provided with an L-shaped pin 21-1. The top surface of the battery holder is provided with a positive positioning post 17-4 and a positive insertion port 17-5. The positive positioning post and the positive hole are arranged coaxially. The positive positioning post extends into the positive spring. The L-shaped pin of the positive spring extends into the battery holder through the positive insertion port and presses against the positive terminal of the battery.

[0054] The positive and negative springs are pressed and fixed between the circuit board and the battery holder, instead of using traditional welding processes. This eliminates the need for welding to achieve conductivity, simplifying the assembly process, reducing the difficulty of manual assembly, improving production efficiency, and lowering production costs.

[0055] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
