Description

Technical Field

[0001] This utility model relates to the field of anti-theft clip technology, specifically a puncture-free protective clip for bagged goods. Background Technology

[0002] In the retail industry, bagged goods are typically protected with anti-theft clips to prevent theft. Existing anti-theft clips mainly consist of a needle and a sleeve. Their working principle is that the needle punctures the packaging bag and inserts into the sleeve to secure the goods. Another type of clip has a hole in the packaging bag, through which the needle passes and is inserted into the sleeve.

[0003] While this structure offers some degree of theft prevention, it still has significant drawbacks: the needles are thin, resulting in a small contact area with the packaging bag; once the protective clip is installed, if it is forcibly pulled, the needles may widen the tear in the bag due to the force, or even completely rip the bag apart, causing the clip to detach and lose its anti-theft function. This defect not only reduces the anti-theft effectiveness but may also affect the integrity of the product and the sales experience due to damaged packaging.

[0004] Therefore, there is an urgent need for an improved anti-theft protective clip structure that can reduce damage to the packaging when securing bagged goods and enhance its resistance to pull-out, thereby improving the reliability of anti-theft measures. Summary of the Invention

[0005] To address the technical problems in the background art, this utility model discloses a puncture-free protective clip for bagged goods.

[0006] This utility model provides a puncture-free protective clip for bagged goods, including a hinged fixed clip and a movable clip, the opening and closing ends of the fixed clip and the movable clip are fixed to the packaging bag by a male and female snap-fit ​​structure;

[0007] When the opening and closing ends of the fixed clip and the movable clip are closed, the packaging bag is snapped into the male and female snap-fit ​​structure of the fixed clip and the movable clip by deformation.

[0008] Furthermore, the opening and closing end of the fixed clamp is provided with a first protrusion extending in the direction of the movable clamp, and the movable clamp is provided with a first sleeve hole for engaging the first protrusion.

[0009] The movable clamp has a second protrusion extending toward the fixed clamp at its opening and closing end, and the fixed clamp has a second sleeve hole for engaging the second protrusion.

[0010] Furthermore, a gap is provided between the outer wall of the first protrusion and the inner wall of the first sleeve hole, and a gap is provided between the end of the first protrusion and the bottom of the first sleeve hole;

[0011] There is a gap between the outer wall of the second protrusion and the inner wall of the second sleeve hole, and there is a gap between the end of the second protrusion and the bottom of the second sleeve hole.

[0012] Furthermore, the cross-sections of both the first and second sets of holes are wedge-shaped;

[0013] The flared end of the first hole faces the first protruding post;

[0014] The flared end of the second hole is directly opposite the second protrusion.

[0015] Furthermore, when the fixed clamp and the movable clamp are closed, there is a gap between their interiors, which is provided as a connecting groove;

[0016] The connecting groove connects the opening end of the first set of holes and the opening end of the second set of holes.

[0017] Furthermore, the portion of the fixing clip located between the hinge and the clamping point is designated as a fixed connection part;

[0018] The portion of the movable clamp located between the hinge and the clamping point is designated as the movable connecting part;

[0019] A gap is provided between the fixed connection part and the movable connection part.

[0020] The beneficial effects of this utility model are:

[0021] 1. The male-female interlocking structure of the fixed and movable clips securely holds the packaging bag at the interlocking point through deformation, significantly increasing the contact area between the clamping surface and the packaging bag. Compared to traditional needle structures, this design can evenly distribute external forces, avoiding stress concentration that can cause tears. Even under strong pulling, it is not easily detached, significantly improving anti-theft reliability.

[0022] 2. Abandoning the traditional needle piercing method, it adopts a deformation clamping principle, achieving fixation without piercing the packaging bag. This not only avoids the problem of the opening widening or the bag tearing, but also maintains the integrity of the product packaging. Attached Figure Description

[0028] 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.

[0029] like Figure 1 As shown, this utility model discloses a puncture-resistant protective clip for bagged goods, including a hinged fixed clip 1 and a movable clip 2, to... Figure 2 For reference, the left ends of the fixed clip 1 and the movable clip 2 are hinged, and the right ends hold and fix the packaging bag.

[0030] like Figure 3 As shown, and with Figure 3 For reference, the lower end of the fixed clamp 1 has symmetrically arranged, vertically extending first mounting holes 11 on both sides. The first mounting holes 11 are blind holes. A vertically extending first protrusion 3 is installed inside each first mounting hole 11. A recessed first positioning recess 12 is provided at the bottom of each first mounting hole 11. The upper end of the first protrusion 3 is engaged within the first positioning recess 12 to achieve installation limitation. The upper end of the first protrusion 3 is fixed to the first positioning recess 12 with adhesive. A second sleeve hole 6 is also provided at the center of the first mounting holes 11. The upper end of the movable clamp 2 has symmetrically arranged, vertically extending first sleeve holes 4 on both sides. A second mounting hole 21 is provided at the center of the first sleeve holes 4. The second mounting hole 21 is a blind hole, and a vertically extending second protrusion 5 is installed inside. A recessed second positioning recess 22 is provided at the bottom of the second mounting hole 21. The lower end of the second protrusion 5 is engaged within the second positioning recess 22 to achieve installation limitation.

[0031] When the fixed clamp 1 and the movable clamp 2 are closed, the first protrusion 3 is coaxially inserted into the first sleeve hole 4, and the second protrusion 5 is coaxially inserted into the second sleeve hole 6. When the opening and closing ends of the fixed clamp 1 and the movable clamp 2 are closed, the packaging bag is clamped between the first protrusion 3 and the first sleeve hole 4, and between the second protrusion 5 and the second sleeve hole 6, through deformation. This design has the following advantages: 1. Through the male-female clamping structure of the fixed clamp 1 and the movable clamp 2, the packaging bag is firmly clamped at the clamping point through deformation, significantly increasing the contact area between the clamping surface and the packaging bag. Compared with the traditional needle structure, this design can evenly distribute the external force, avoid stress concentration leading to tearing, and is not easy to detach even under strong pulling, significantly improving the reliability of anti-theft. 2. Abandoning the traditional needle piercing method, the deformation clamping principle is adopted, which can achieve fixation without piercing the packaging bag. This not only avoids the problem of widening the tear or tearing of the bag, but also maintains the integrity of the product packaging.

[0032] A gap is provided between the side wall of the first protrusion 3 and the inner wall of the first sleeve hole 4, and a gap is provided between the end of the first protrusion 3 and the bottom of the first sleeve hole 4. A gap is provided between the side wall of the second protrusion 5 and the inner wall of the second sleeve hole 6, and a gap is provided between the end of the second protrusion 5 and the bottom of the second sleeve hole 6. This gap not only provides space for the packaging bag to be accommodated, but also provides space for the deformation of the packaging bag, and eliminates the positional accuracy requirements between the protrusion and the sleeve hole, so that the protrusion can be stably inserted into the sleeve hole.

[0033] Furthermore, the first protrusion 3, the second protrusion 5, the first sleeve hole 4, and the second sleeve hole 6 are all complete cylinders, and the deformation area of ​​the packaging bag is also a complete cylinder, which can further increase the resistance of the protective clip detaching from the packaging bag and improve the connection strength between the protective clip and the packaging bag. The ends of the first protrusion 3 and the second protrusion 5 are flat end faces, which are blunt faces, and will not cause the packaging bag to be torn.

[0034] The cross-sections of the first sleeve hole 4 and the second sleeve hole 6 are both wedge-shaped; the flared end of the first sleeve hole 4 faces the first protruding post 3; the flared end of the second sleeve hole 6 faces the second protruding post 5. This arrangement allows the first sleeve hole 4 and the second sleeve hole 6 to have a guiding function, facilitating the deformation of the packaging bag. Moreover, the deformation angle of the packaging bag at the opening of the sleeve hole is an obtuse angle, making it less prone to being cut.

[0035] When the fixed clamp 1 and the movable clamp 2 are closed, the fixed clamp 1 forms part of the first sleeve hole 4, and the movable clamp 2 forms part of the second sleeve hole 6. A gap is provided between the two parts, which is designated as a connecting groove 7. The connecting groove 7 connects the open ends of the first sleeve hole 4 and the second sleeve hole 6. The connecting groove 7 provides sufficient space for the packaging bag, preventing it from being damaged due to excessive compression. Furthermore, the connecting groove 7 simplifies the structure of the fixed clamp 1 and the movable clamp 2, thereby simplifying the molding die structure and reducing costs.

[0036] To ensure stable closure of the clamping ends of the fixed clamp 1 and the movable clamp 2 and to provide stable pressure, the portion of the fixed clamp 1 located between the hinge and the clamping point is designated as a fixed connecting part 13; the portion of the movable clamp 2 located between the hinge and the clamping point is designated as a movable connecting part 23; a gap is provided between the fixed connecting part 13 and the movable connecting part 23. This gap ensures that when the fixed clamp 1 and the movable clamp 2 are closed, their clamping ends are not obstructed by the fixed connecting part 13 and the movable connecting part 23, thus maintaining stable pressure on the packaging bag.

[0037] 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.
