Anti-theft tags for bags with sounding mechanism

Abstract

This invention provides a bag-type anti-theft tag with a self-ringing device, comprising a fixed block and a movable block hinged at one end and openable at the other. A buzzer and a trigger switch electrically connected to the buzzer are mounted on the fixed block; a trigger block is mounted on the movable block. The opening and closing of the fixed and movable blocks causes the trigger block to press or disengage from the trigger switch; when the trigger block disengages from the trigger switch, the buzzer is energized. By integrating the buzzer and trigger switch on the fixed block and linking them with the trigger block on the movable block, the buzzer immediately activates and sounds when the tag is forcibly pulled open (the trigger block disengages from the switch). This active alarm mechanism significantly improves the anti-theft response speed, enabling staff to detect abnormal behavior in real time and overcoming the shortcomings of traditional passive tag protection.

Description

Technical Field

[0001] This utility model relates to the field of anti-theft tag technology, specifically a bag-type anti-theft tag with a self-sounding device. Background Technology

[0002] In the retail industry, theft prevention management of bagged goods has always been a significant challenge. Traditional anti-theft tags typically employ a structure consisting of a fixed block and a hinged movable block, which clamps the product packaging bag by closing the opening and closing ends to achieve the anti-theft function.

[0003] However, in the existing design of anti-theft tags, the fixed and movable blocks can be easily pulled apart when subjected to sufficient external force (such as simultaneous pulling by both hands), causing the anti-theft function to fail. This method of destruction is covert and difficult for monitoring personnel to detect in a timely manner, thus posing a significant risk to product theft prevention.

[0004] Therefore, there is an urgent need for an improved anti-theft tag structure that can be detected by staff in a timely manner when it is forcibly pulled open, in order to solve the above-mentioned problems in the existing technology. Utility Model Content

[0005] To address the technical problems in the background art, this utility model discloses a bag-type anti-theft tag with a self-ringing device.

[0006] This utility model provides a bag-type anti-theft tag with a self-sounding device, including a fixed block and a movable block that are hinged at one end and open and closed at the other end. A buzzer and a trigger switch electrically connected to the buzzer are installed on the fixed block.

[0007] A trigger block is installed on the active block;

[0008] The opening and closing of the fixed block and the movable block causes the trigger block to press or disengage from the trigger switch;

[0009] When the trigger block disengages from the trigger switch, the buzzer is powered on.

[0010] Furthermore, the fixing block is hollow, and a PCB board is installed inside it;

[0011] A mounting plate is provided on the side of the fixed block that faces the movable block;

[0012] The mounting plate has through holes;

[0013] The trigger switch is located inside the through hole, with its trigger head extending beyond the mounting plate.

[0014] Furthermore, the mounting plate is also provided with a recessed positioning recess at the position of the through hole;

[0015] When the fixed block and the movable block are closed, the trigger block is engaged in the positioning recess.

[0016] Furthermore, the opening and closing ends of the fixed block and the movable block are respectively provided with a first needle and a second needle;

[0017] The movable block is provided with a first set of holes corresponding to the first needle;

[0018] The fixing block is provided with a second set of holes corresponding to the second needle;

[0019] When the fixed block and the movable block are closed, the first needle is inserted into the first sleeve hole; the second needle is inserted into the second sleeve hole.

[0020] Furthermore, the first and second needles are arranged collinearly and alternately.

[0021] Furthermore, the first and second needles have the same structure, both consisting of a cylindrical base and a sharp tip;

[0022] Both the fixed block and the movable block are equipped with sleeves;

[0023] The base is inserted into the sleeve.

[0024] The beneficial effects of this invention are as follows: By integrating a buzzer and a trigger switch on the fixed block and linking them with the trigger block on the movable block, the buzzer immediately sounds when the tag is forcibly pulled open (the trigger block disengages from the switch). This active alarm mechanism significantly improves the anti-theft response speed, enabling staff to detect abnormal behavior in real time and overcoming the shortcomings of traditional passive tag protection.

[0033] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0034] like Figure 1 and Figure 2 As shown, this utility model discloses a bag-type anti-theft tag with a self-ringing device, including a fixed block 1 and a movable block 2 that are hinged at one end and open and close at the other end.

[0035] like Figure 3 As shown, the opening and closing end of the fixed block 1 is provided with a first needle 10 pointing towards the movable block 2, and the movable block 2 is provided with a first sleeve hole 12 corresponding to the first needle 10; the opening and closing end of the movable block 2 is provided with a second needle 11 pointing towards the fixed block 1, and the fixed block 1 is provided with a second sleeve hole 13 corresponding to the second needle 11. When the fixed block 1 and the movable block 2 are closed, the first needle 10 passes through the packaging bag and is inserted into the first sleeve hole 12; the second needle 11 passes through the packaging bag and is inserted into the second sleeve hole 13, thus fixing the anti-theft label to the packaging bag and realizing the anti-theft function.

[0036] like Figure 6 As shown, the first needle 10 and the second needle 11 have the same structure, both consisting of a cylindrical base 14 and a sharp needle tip 15; both the fixed block 1 and the movable block 2 are provided with sleeves 16; the base 14 is inserted into the sleeve 16. The sleeve 16 is used for needle installation and is fixed by adhesive. This design not only facilitates needle installation, but also simplifies the structure of the fixed block 1 and the movable block 2 by separating the needle from them, thus reducing their manufacturing cost. The cylindrical shape of the base 14 increases the contact area between the needle and the sleeve 16, resulting in higher structural strength after installation.

[0037] The first needle 10 and the second needle 11 are arranged collinearly and alternately. The advantages of this arrangement are: 1. The collinear and alternate arrangement of the needles creates a cross-piercing effect when closed, allowing them to penetrate the product packaging more securely. If the label is forcibly pulled open, the alternate arrangement of the needles generates greater tearing resistance, causing the packaging to break rather than the label to separate, thus preventing theft and providing an anti-theft warning by damaging the product packaging. 2. The collinear arrangement ensures that the needles experience force in the same direction, avoiding stress concentration or skew failure caused by asymmetrical layouts. Simultaneously, it forms a double anti-theft guarantee with the triggering mechanism of the buzzer 3, improving the reliability of the label.

[0038] like Figure 4 As shown, and with Figure 4 For reference, the fixed block 1 is hollow, with a horizontally arranged mounting plate 7 at its upper end. Inside the fixed block 1, near the mounting plate 7, is a horizontally arranged PCB board 6. A buzzer 3 is mounted on the lower left side of the PCB board 6, and a trigger switch 4 is mounted on the upper right side of the PCB board 6, electrically connected to the buzzer 3 via the PCB board 6. The mounting plate 7 has a through hole 8 running vertically through it, and the trigger switch 4 is located within the through hole 8, with its trigger head extending upwards beyond the mounting plate 7. A trigger block 5 corresponding to the trigger switch 4 is fixed to the lower end face of the movable block 2. When the fixed block 1 and movable block 2 are closed, the trigger block 5 applies pressure to the trigger head, causing it to retract into the trigger switch 4. This triggers the switch 4, de-energizing the buzzer 3 and preventing it from emitting sound. When the fixed block 1 and movable block 2 move away from each other, the trigger block 5 disengages from the trigger head, which then resets under elastic pressure, energizing the buzzer 3 and producing a sound.

[0039] The above setup integrates a buzzer 3 and a trigger switch 4 on the fixed block 1, which are linked to a trigger block 5 on the movable block 2. When the tag is forcibly pulled open (trigger block 5 disengages from the switch), the buzzer 3 is immediately powered on and sounds. This active alarm mechanism significantly improves the anti-theft response speed, enabling staff to detect abnormal behavior in real time and compensating for the shortcomings of traditional passive tag protection.

[0040] The fixed block 1 also contains a decoder installed on the PCB board 6. When the anti-theft tag is opened normally, the decoder will turn off the power to the buzzer 3, so that it will not make a sound accidentally.

[0041] like Figure 4 and Figure 5As shown, in this embodiment, the upper surface of the mounting plate 7 is also provided with a recessed positioning recess 9 that covers the through hole 8. The positioning recess 9 is contoured to the trigger block 5. When the fixed block 1 and the movable block 2 are closed, the trigger block 5 is engaged in the positioning recess 9, thereby limiting the position of the trigger block 5. With this configuration, the trigger block 5 presses the trigger head more stably, and there will be no misalignment that would cause the trigger block 5 to detach from the trigger head. Moreover, the engagement of the trigger block 5 with the positioning recess 9 also limits the position of the fixed block 1 and the movable block 2 when they are closed, resulting in higher structural strength.

[0042] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
