Description

Technical Field

[0001] This utility model relates to an anti-theft device for goods, specifically a clip tag. Background Technology

[0002] Anti-theft tags can protect various types of goods from theft. Their working principle is as follows: when locking is required, press the button to extend the nail rod, which passes through the protected object and extends into the lock cylinder to be clamped and fixed; when unlocking is required, bring the lock cylinder close to the unlocking device, and the lock cylinder opens under the action of magnetic force, releasing the nail rod, which automatically retracts and releases the protected object.

[0003] The lock cylinder of the anti-theft tag consists of a steel sleeve, a three-ball seat, steel balls, and a spring. When locking, the spring pushes the steel balls in the three-ball seat against the inner wall of the steel sleeve, tightly clamping the nail rod inserted in the center of the three-ball seat. When unlocking, the unlocking device uses magnetic force to attract the three-ball seat, compressing the spring, and the steel balls no longer clamp the nail rod.

[0004] This lock cylinder is widely used in shopping malls, supermarkets and other places. The lock picks that come with it are also quite common and can be used interchangeably, which poses a significant security risk. In addition, when this lock cylinder is struck, the three ball joint may loosen, which may lead to accidental unlocking and makes it unreliable. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings in the above-mentioned background technology and provide a clip label that is easy to use, simple in structure, and has a good anti-theft effect.

[0006] The technical solution of this utility model is:

[0007] A clip tag includes a main clip body, a button with a locking pin, and an alarm component; the button is retractably positioned on the upper clip arm of the main clip body; characterized in that: the upper clip arm of the main clip body is provided with a slidable locking tooth, a spring for ejecting the button from the upper clip arm, a spring plate for preventing the locking tooth from resetting, and a linkage structure connecting the button and the locking tooth.

[0008] In the linkage structure, the button is provided with a guide groove, and the locking teeth are provided with a guide block that cooperates with the guide groove.

[0009] The front end of the tooth is provided with two guide arms, and the inner side of the guide arms is provided with a guide block; the button is slidably positioned between the two guide arms, and the two sides of the button are provided with guide grooves.

[0010] The spring plate is positioned above the locking teeth; the spring plate has a downwardly protruding spring piece.

[0011] The top surface of the locking tooth is provided with a groove for accommodating the spring clip, and a baffle that can cooperate with the spring clip is provided on the side of the groove near the rear end of the locking tooth.

[0012] The bottom surface of the upper clamping arm and the top surface of the lower clamping arm of the main clamping body are provided with locking holes for matching locking pins.

[0013] The alarm component is a coil or an RFID tag.

[0014] The beneficial effects of this utility model are:

[0015] The working principle of this utility model is simple and reliable. Locking can be completed by pressing the button. When locking, it does not rely on the traditional three-ball structure to clamp the nail rod, but adopts a brand-new locking method of spring-tooth-button. It has high reliability, is not afraid of external force, and can only be unlocked by a special lock pick. Conventional lock picks are not universal, which greatly improves the anti-theft performance. Attached Figure Description

Detailed Implementation

[0030] 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.

[0031] like Figure 1 As shown, a clip label includes a main clip body 1, a button 2, a locking pin 3, an alarm component 4, a locking tooth 5, a spring 6, a spring plate 7, and a linkage structure.

[0032] The main clamping body is composed of two half-shells 1-1. The main clamping body is U-shaped and includes an upper clamping arm 1.1 and a lower clamping arm 1.2 arranged in parallel. A small gap is maintained between the upper clamping arm and the lower clamping arm to prevent accidental injury during use. The object to be protected (such as clothing 9) is placed in the gap.

[0033] The button, locking pin, locking teeth, spring, linkage structure, and spring plate are mounted on the upper clamping arm. The button is telescopically and slidably fixed on the upper clamping arm, and the sliding direction of the button is vertical. Figure 4 (In the vertical direction), the spring is located below the button, with the two ends of the spring pressing against the bottom surface of the button and the inner wall of the upper clamping arm, respectively. When unlocking, the spring pushes the button to extend upward from the top surface of the upper clamping arm, and when locking, the button descends into the upper clamping arm and presses the spring.

[0034] The locking pin is arranged coaxially with the button. The top end of the locking pin is pressed and fixed in the button by the button cap 8. The bottom end of the locking pin extends downward from the bottom of the button. When unlocking, the locking pin is fully retracted into the upper clamping arm. When locking, the locking pin extends out from the upper clamping arm and inserts into the lower clamping arm. The bottom surface of the upper clamping arm and the top surface of the lower clamping arm are both provided with locking holes for matching the locking pin.

[0035] The locking teeth can be horizontally slidably fixed in the upper clamping arm. Figure 4(Horizontal direction) The button and the locking teeth are connected by a linkage structure. A spring plate is positioned above the locking teeth to prevent them from resetting. When locking, pressing the button causes the locking teeth to move backward via the linkage structure, and the spring plate then locks the teeth. When releasing the button, although it is spring-loaded, it cannot move the locking teeth forward to reset, so the button remains pressed. When unlocking, using a lock pick near the spring plate causes the spring plate to deform due to magnetic force and disengage from the locking teeth. The button, spring-loaded, moves the locking teeth forward to reset, causing the button to pop up.

[0036] The linkage structure includes a guide groove 2-1 on the button and a guide block 5-1 on the locking teeth. The guide groove and guide block are arranged at an angle, so that the locking teeth can move horizontally when the button moves up and down. Wherein: Figure 8 and Figure 9 As shown, the front end of the tooth ( Figure 4 The right end of the button is provided with two guide arms 5-2, which are L-shaped (including the first extension section 5-2-1 and the second extension section 5-2-2). The first extension section extends horizontally from the front end of the tooth, and the second extension section extends upward at a certain angle from the front end of the first extension section. A certain distance is maintained between the two guide arms. A guide block is provided on the inner side of the second extension section. The button can be vertically slidably positioned between the two guide arms. Guide grooves are provided on both sides of the button, and the guide block is embedded in the guide groove.

[0037] The spring plate is equipped with a spring piece 7-1, such as Figure 10 As shown, the spring plate is elongated, and the spring piece is located in the middle of the spring plate and protrudes towards the locking teeth. When locking, the spring plate and the spring piece naturally open at a certain angle. When unlocking, the spring piece is pulled towards the spring plate by the magnetic force of the unlocking device (the angle becomes smaller). The spring piece is made by stamping and bending.

[0038] The top surface of the locking tooth has a groove 5-3, and a baffle 5-4 is inclinedly arranged on the side of the groove near the rear end of the locking tooth. When locking, the spring extends downward into the groove and the baffle presses against the movable end 7-2 of the spring, preventing the locking tooth from resetting. When the unlocking device is brought close to the spring plate, the movable end of the spring slides upward along the baffle under the action of magnetic force and completely disengages from the groove. The locking tooth is no longer blocked by the spring, so pressing the button drives the locking tooth to reset and complete the unlocking. After unlocking, the unlocking device is removed. When the spring opens, it presses against the top of the baffle, keeping the spring in a compressed state. When locking again, the change in the position of the locking tooth causes the spring to fully open and prevent the locking tooth from resetting.

[0039] The alarm component can be installed in either the upper or lower clamping arm. The alarm component can be a coil, an RFID tag, or a combination of both. The alarm will be triggered if a thief carrying an unremoved item passes by the supermarket antenna.

[0040] The working principle of this utility model is as follows:

[0041] 1. Not in use:

[0042] like Figure 1 , Figure 3 , Figure 6 As shown, the button pops up, the locking pin retracts into the upper clamping arm, and the locking teeth are positioned to the right.

[0043] 2. Lock:

[0044] like Figure 2 As shown, place garment 9 between the upper and lower clamping arms, press the button and compress the spring. The locking pin extends downward from the upper clamping arm, passes through the garment, and then inserts into the lower clamping arm. Figure 7 As shown, the button simultaneously moves the locking teeth (to the left) through the linkage structure, and the spring pops out to block the locking teeth, keeping the locking pin extended, thus completing the locking process.

[0045] Because the spring plate is made of metal and has a flat shape, it is difficult to deform when hit by external force, and has good reliability.

[0046] 3. Unlock

[0047] The lock pick (omitted in the figure) is long and narrow (with a built-in bar magnet). When the lock pick is placed above the upper clamping arm (the upper clamping arm has a notch 1.3 for positioning the lock pick), the bar magnet, which is close to the spring, can generate enough magnetic force to attract the spring to disengage from the groove. The locking teeth disengage from the spring, and the spring pushes the button and locking teeth to reset, thus completing the unlocking.

[0048] Conventional lock picks are frustum-shaped, which does not match the shape of this invention. The magnet cannot be tightly attached to the spring, and the generated magnetic force is insufficient to act on the spring, thus failing to unlock. In comparison, this invention has better security.

[0049] 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.
