Description

Technical Field

[0001] This utility model relates to a commodity anti-theft device, specifically a pull-tab alarm tag. Background Technology

[0002] Nail tags are a mature product on the market, mainly consisting of a clamp and a nail. The nail, after penetrating the product, is inserted into the clamp and secured, thus providing anti-theft protection. Nail tags can also have an alarm function; their clamp has a built-in microswitch. When the nail is inserted, touching the microswitch activates the anti-theft monitoring. When the nail loosens, the microswitch releases, triggering the clamp's alarm.

[0003] Nail tags with alarm functions have the following disadvantages: 1. Inconvenient to use: When installing the nail tag, you need to press the reset switch to power on first, then insert the nail through the product and into the clamp to activate the anti-theft monitoring; when the clamp alarms, if you use a lock pick to pull out the nail, the clamp will continue to alarm. Only by pressing the reset switch with the nail can the alarm be deactivated. 2. The clamping device needs to be equipped with micro switches, reset switches and other components, which makes the structure complex and the assembly cumbersome, making it difficult to reduce product costs.

[0038] 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.

[0039] Example 1 like Figure 1 As shown, the pull-tab alarm label includes a housing 1, a lock cylinder 2, a main board 3, a battery 4, a buzzer 6, and a coil 7.

[0040] The lock cylinder, main board, battery, buzzer, and coil are all housed within the housing. The housing has a lock hole 1.1, and the lock cylinder is a three-ball lock cylinder. The lock hole and lock cylinder are arranged coaxially. After the pull pin is inserted into the lock hole, it can extend into the lock cylinder, and the lock cylinder then clamps and fixes the pull pin to achieve locking.

[0041] The housing consists of an upper shell 1-1 and a lower shell 1-2. The upper shell is provided with the lock hole, and the lower shell is provided with an indicator light hole 1.2, a groove 1.3 for accommodating the lock cylinder, and a sound outlet hole 1.4.

[0042] The above structure is the same as that of the prior art. The improvement of this embodiment is that: It also includes a pair of springs 5, which are electrically connected to the main board and are used to detect the status of the pull pins to determine whether the lock is engaged and for anti-theft monitoring. The springs are set between the keyhole and the lock cylinder, so the keyhole and the lock cylinder maintain a certain vertical distance to facilitate the placement of the springs. The space between the keyhole and the lock cylinder is a pull pin channel for the pull pins to pass through.

[0043] like Figure 12 As shown, the spring is divided into an upper part 5-1, a middle part 5-2, and a lower part 5-3. The lower part of the spring is fixed to the main board, and the upper part of the spring can be U-shaped. A certain distance is maintained between the upper parts of the U-shaped springs (the distance is perpendicular to the axis of the rivet channel, i.e., ...). Figure 9(Horizontal direction), the spacing is smaller than the outer diameter of the pull stud. When the pull stud is not inserted, the two spring contacts do not contact each other; when the pull stud is inserted, the two spring contacts are connected through the pull stud to form a conductive path.

[0044] like Figure 9 As shown, the spring clips can be arranged left and right, and the upper U-shaped parts of the spring clips can be staggered vertically (the spring clip on the right is higher than the spring clip on the left). The curved ends of the upper U-shaped parts of the spring clips extend from both sides towards each other and into the rivet channel. When the rivet is not inserted into the rivet channel, the spring clips on both sides are staggered vertically, which shortens the distance between them. When the rivet is inserted into the rivet channel, the spring clips press against the rivet from both sides, and the spring clips are connected through the rivet.

[0045] The motherboard is equipped with an indicator light 3-1 and a Hall sensor 3-2. The indicator light extends from the indicator light hole in the lower casing. The buzzer is used to issue an alarm. The Hall sensor is used to monitor changes in magnetic force.

[0046] The main board can be located between the lock hole and the lock cylinder. The main board is provided with 3-4 through holes, which are arranged coaxially with the pull pin channel. The pull pin first passes through the lock hole, then through the through hole of the main board, and finally extends into the lock cylinder.

[0047] The working principle of Example 1 is as follows: 1. Lock The tack is inserted through the product and then into the lock hole. As the tack passes through the tack channel, it squeezes the springs on both sides and finally extends into the lock cylinder to be fixed. The springs on both sides are squeezed by the tack and hold it tightly against the tack. Since the tack is made of metal, the springs are connected through the tack to form a conductive path. At this time, the tag enters the anti-theft monitoring state.

[0048] 2. Unlock When the magnetic lock pick is brought close to the lock cylinder of the tag, the lock cylinder releases the pull pin. At the same time, the Hall sensor detects the magnetic field of the magnetic lock pick. After the pull pin is pulled out, although the conductive path is broken, no alarm will be triggered, and the unlocking is completed.

[0049] 3. Anti-theft protection When the pull pin is forcibly pulled by an external force and illegally pulled out, the conductive path is broken. Since the Hall sensor does not detect the magnetic field of the magnetic unlocking device, an alarm is triggered and the buzzer sounds.

[0050] If you carry the goods through the mall exit without removing the tag, the antenna at the exit will trigger an alarm, and the tag itself will also sound an alarm.

[0051] 4. Deactivate alarm Once the alarm is activated, bring the magnetic lock pick close to the lock cylinder of the tag. The Hall sensor detects the magnetic field of the magnetic lock pick, and the alarm sound turns off.

[0052] 5. This utility model can activate the motherboard and lock the device simply by inserting the pull pin, which is very convenient to operate. In contrast, the existing technology requires pressing the power switch to activate the motherboard before inserting the pull pin.

[0053] This invention allows you to unlock the lock simply by using a magnetic unlocking tool to remove the pull pin, while existing technology still triggers an alarm after the pull pin is removed, requiring you to press the reset power switch to deactivate the alarm.

[0054] This invention eliminates the need for microswitches, reset switches, and other components, simplifying the overall structure, reducing assembly steps, and lowering product costs.

[0055] Example 2 Compared with Embodiment 1, the improvement of Embodiment 2 is that it also includes a spring module.

[0056] The spring plate module, lock cylinder, and pull pin channel are arranged coaxially. The spring plate module is fixed to the main board. Figures 8 to 13 As shown, the spring module includes a support frame 8, a pressure cap 9, and the spring 5. The spring is inserted on both sides of the support frame, and the pressure cap is fixed to the top of the support frame to restrict the movement of the spring.

[0057] The support frame is annular, with its inner hole coaxial with the rivet channel. Trapezoidal platforms 8-1 are located on both sides of the support frame, arranged at different heights. Figure 9 As shown, the trapezoidal platform on the right is higher than the trapezoidal platform on the left. The side of the trapezoidal platform is provided with an inclined slot 8-2 for installing a spring clip, and the side wall of the slot is provided with a locking block 8-3.

[0058] The upper part (U-shaped) of the spring is mounted on the top surface of the trapezoidal platform, so the upper parts of the U-shaped springs on both sides are staggered vertically. Figure 9 The upper part of the spring on the right side is higher than the upper part of the spring on the left side. The middle part of the spring is set in the slot, and the middle part of the spring has a notch 5-4 that mates with the locking block, so the spring cannot slide up and down along the slot. The lower part of the spring extends from the bottom surface of the support frame and is electrically connected to the main board.

[0059] The pressure cap is slightly larger than the support frame, and the pressure cap is provided with a spring slot 9-1. The extension direction of the spring slot is the direction of the line connecting the two trapezoidal platforms. Figure 9 (Horizontal direction), the rivet channel passes through the spring clip slot, and the top surface of the pressure cap is provided with baffles 9-2 located on both sides of the spring clip slot, with the upper part of the spring clip located between the baffles. When the rivet passes downward through the spring clip module, although the spring clip is squeezed by the rivet, due to the limiting effect of the pressure cap (otherwise the middle part of the spring clip is easily deformed, causing the upper part of the U-shape to move to both sides), only the upper part of the U-shape of the spring clip located between the baffles deforms. Therefore, the spring clip tightly presses against the rivet, ensuring a stable electrical connection. The spring clip slot can prevent the upper part of the U-shape of the spring clip from moving to both sides. Figure 9The baffle moves to the left and right sides, preventing the upper part of the U-shaped piece from moving towards the left and right sides. Figure 10 It moves to the left and right sides.

[0060] The pressure cap and the support frame, as well as the spring module and the main board, are fixed by a connecting structure. The connecting structure includes: an upper connecting post 8-4 extending upward from the support frame and an upper connecting hole 9-3 provided on the pressure cap, the upper connecting hole and the upper connecting post being tightly fitted; a lower connecting post 9-4 extending downward from the pressure cap and a lower connecting hole 3-5 provided on the main board, the lower connecting hole and the lower connecting post being tightly fitted.

[0061] When locking, the pull pin passes through the product and then inserts into the lock hole. As the pull pin passes through the pull pin channel, it passes through the baffle of the pressure cap (while squeezing the spring), the spring slot of the pressure cap, the inner hole of the support bracket, and the through hole of the main board, and finally extends into the lock cylinder and is fixed.

[0062] Because the spring clip module can be pre-assembled, label assembly is simple: just install the spring clip module on the motherboard and then solder the spring clips, making production very convenient. At the same time, the spring clip module ensures the clamping force of the spring clips, preventing accidental alarms caused by poor contact between the spring clips and the pull studs.

[0063] Example 3 Compared with Example 2, the improvement of Example 3 is that it also includes a silicone pillar 10 and a gasket 11.

[0064] A spring plate module, a main board, a silicone pillar, and a washer (these components are fixed between the upper and lower shells) are sequentially arranged between the lock hole and the lock cylinder. The spring plate module, silicone pillar, washer, lock cylinder, and pull rivet channel are arranged coaxially. The silicone pillar has a central hole for the pull rivet to pass through. The washer has a central hole 11-2 for the pull rivet to pass through. The central hole of the silicone pillar, the washer hole of the washer, and the pull rivet channel are arranged coaxially. The pull rivet can pass through the lock hole, spring plate module, silicone pillar, and washer in sequence before being inserted into the lock cylinder.

[0065] The silicone pillar passes through the inner hole of the support frame and the through hole of the main board. The top surface of the silicone pillar abuts against the bottom surface of the pressure cap, and the bottom surface of the silicone pillar abuts against the top surface of the gasket. The gasket is located between the main board and the lock cylinder, and the gasket and the main board are isolated from each other by the silicone pillar and cannot make contact.

[0066] The bottom surface of the motherboard has several pads 3-3 arranged around through-holes, these pads being adjacent positive and negative terminals. The spacer is made of metal, and its top surface has several bumps 11-1 arranged around the spacer hole. The number of pads and bumps is the same. Figure 20As shown, the pads and bumps are arranged vertically and vertically. When the gasket moves towards the motherboard, each bump touches a pad. To prevent the gasket from rotating axially and causing misalignment between the pads and bumps, the lower housing has a lower positioning groove 1.5 arranged around the lock cylinder. The edge of the gasket has a positioning block 11-3 embedded in the lower positioning groove, allowing the gasket to move up and down but not rotate. The upper housing has an upper positioning groove 1.6 for positioning the spring module, and the baffle of the pressure cap is embedded in the upper positioning groove.

[0067] When an external force forcibly pulls the rivet, but the rivet is not illegally pulled out due to insufficient force, although the conductive path remains connected, Example 3 can still trigger an alarm to prevent the tag from being further damaged: When the rivet is pulled, the lock cylinder is forced to squeeze the silicone pillar. The silicone pillar is deformed under pressure, causing the pad to contact the motherboard. Since the pads and bumps are arranged vertically and vertically, when the bumps touch the pads, the metal pad connects the positive and negative pads, thereby triggering an alarm.

[0068] 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.
