Description

Technical Field

[0001] This utility model relates to the field of packaging connection structure technology, specifically to a drop-proof anti-displacement buckle and a wine box. Background Technology

[0002] Wine boxes, as packaging containers for alcoholic beverages, not only protect the bottles but also serve as display and marketing tools, thus they are widely used in the wine industry.

[0003] In most wine boxes, the box body and the base supporting the wine bottle are connected by plastic clips. In practical applications, these clips are divided into anti-counterfeiting clips that serve both a connecting and anti-counterfeiting function, and non-anti-counterfeiting clips that only serve a connecting function. For non-anti-counterfeiting clips, one type of non-anti-counterfeiting clip in existing technology is... Figure 1 As shown, the buckle 100 includes a positioning post 1, one end of which is provided with a cover plate 2, and the other end of which is provided with a plurality of support petals 3 along the circumferential direction. The support petals 3 can be reset after compression, and their maximum size is larger than the diameter of the positioning post 1. Figure 2 As shown, the box body 200 is provided with a positioning hole that cooperates with the positioning post 1, and the base 300 is provided with an installation hole (the diameter is larger than the positioning hole) at the position corresponding to the positioning hole. During installation, the support petal 3 is inserted into the base 300 to complete the installation. When the wine box 200 is opened, the buckle 100 is pulled outward to squeeze the support petal 3 inward, and the buckle 100 can be removed.

[0004] However, the requirements for wine boxes are becoming increasingly stringent. Some wine boxes need to undergo drop tests to ensure their impact resistance and the safety of the wine. Existing clips frequently fail to disengage or even detach during drop tests. Therefore, preventing clip disengagement during drops is a pressing issue that needs to be addressed. Utility Model Content

[0005] The purpose of this utility model is to provide a drop-proof anti-disengagement buckle and wine box to solve the defects of existing buckles and prevent the buckle from disengaging when the wine box is dropped.

[0006] This utility model is achieved through the following technical solution:

[0007] A drop-prevention anti-retraction buckle includes a positioning post, a cover plate, and a support petal. The cover plate is located at one end of the positioning post, and the support petal is located at the other end of the positioning post. It also includes an anti-retraction structure. There are two support petals symmetrically arranged on both sides of the positioning post. The anti-retraction structure includes a connecting body and two anti-retraction ribs symmetrically arranged on both sides of the connecting body. The connecting body is located between the two support petals and connected to the positioning post. One end of the anti-retraction rib is connected to the end of the connecting body and forms a barb shape with the side of the connecting body.

[0008] Optionally, the end of the connector has a notch between the two anti-retraction ribs.

[0009] Optionally, the notch is V-shaped.

[0010] Optionally, the anti-retraction rib has a guide radius on the inner side of the end away from the connector.

[0011] Optionally, a reinforcing rib is provided between the connecting body and the supporting petal.

[0012] Optionally, the outer surface of the support petal extends in a circumferential direction in a drum-shaped structure with a larger diameter in the middle and smaller diameters at both ends. The maximum diameter of the drum-shaped structure is greater than the diameter of the positioning post, and the diameter of the end of the drum-shaped structure away from the positioning post is smaller than the diameter of the positioning post.

[0013] Optionally, the anti-retraction structure is made of PE or PP material.

[0014] This utility model also provides a wine box, including a box body and a base, wherein the box body and the base are connected by the drop-proof anti-dislodgement buckle described in any one of the above.

[0015] The technical solution of this utility model has at least the following advantages and beneficial effects: In this utility model, based on the existing plastic buckle, two of the support petals are replaced with the anti-retraction structure. In the anti-retraction structure, the anti-retraction clamp and the connecting body form a barb shape. Because the plastic part is tough, the anti-retraction rib can bend inward during installation. After the buckle is installed, the anti-retraction rib returns to its original shape, which can restrict the buckle from coming out, making the buckle more reliable and preventing the buckle from coming out or falling off when the wine box is dropped.

[0024] refer to Figures 3-6 This embodiment provides a drop-proof anti-retraction buckle, including a positioning post 1, a cover plate 2, a support petal 3 and an anti-retraction structure 4. The buckle 100 is usually made of plastic, and in actual applications, the buckle 100 is integrally injection molded.

[0025] The cover plate 2 is located at one end of the positioning post 1, and the support petal 3 and the anti-retraction structure 4 are located at the other end of the positioning post 1. There are two support petals 3, which are symmetrically arranged on both sides of the positioning post 1. The anti-retraction structure 4 includes a connecting body 402 and two anti-retraction ribs 401 symmetrically arranged on both sides of the connecting body 402. The connecting body 402 is located between the two support petals 3 and connected to the positioning post 1. One end of the anti-retraction rib 401 is connected to the end of the connecting body 402 and forms a barb shape with the side of the connecting body 402.

[0026] It is worth noting that, due to the flexibility of the plastic parts, the anti-retraction rib 401 can bend inward during installation. After the clip 100 is installed, the anti-retraction rib 401 returns to its original shape, preventing the clip 100 from disengaging and making the clip 100 more reliably secured, thus preventing the clip 100 from disengaging or falling off when the wine box is dropped. Simultaneously, when removing the clip 100, the anti-retraction rib 401 can also bend outward (e.g., ...). Figure 7 As shown in the image, it can fulfill the normal opening function of the wine box.

[0027] In this embodiment, the anti-retraction structure 4 is made of PE (polyethylene) or PP (polypropylene) material. Furthermore, the entire buckle 100 is made of PE or PP material. It is worth noting that PE is soft and has good toughness, while PP has outstanding resistance to bending fatigue (it can be folded tens of thousands of times without breaking). Both ensure that the anti-retraction rib 401 bends well inwards or outwards. It should be understood that in other embodiments of this utility model, the anti-retraction structure 4 can, of course, be made of other similar materials.

[0028] In this embodiment, the end of the connector 402 has a notch 4021 between the two anti-retraction ribs 401, which facilitates the smooth folding of the anti-retraction ribs 401. Furthermore, the notch 4021 is V-shaped. Based on this, the anti-retraction structure 4 is generally similar to a "W" shape. In other embodiments of this utility model, as long as the anti-retraction ribs 401 can be folded inward and outward, they can of course be designed into other shapes.

[0029] The anti-retraction rib 401 has a guide rounded corner 4011 on the inner side of the end away from the connector 402. When the buckle 100 is removed, the guide rounded corner 4011 contacts the edge of the mounting hole on the base 300, so that the buckle 100 can be removed smoothly.

[0030] In this embodiment, a reinforcing rib 5 is provided between the connector 402 and the support petal 3. The reinforcing rib 5 can prevent the support petal 3 from breaking off at the root.

[0031] The outer surface of the support petal 3 extends in a circumferential direction in a drum-shaped structure, with a larger diameter in the middle and smaller diameters at both ends. The maximum diameter of the drum-shaped structure is larger than the diameter of the positioning post 1, while the diameter of the end of the drum-shaped structure away from the positioning post 1 is smaller than the diameter of the positioning post 1. This design ensures that during installation, the end of the support petal 3 away from the positioning post 1 is positioned within the positioning hole on the housing 200. As the buckle 100 is pushed inward, the outer side of the support petal 3 is gradually compressed. After passing the maximum diameter of the drum-shaped structure, the support petal 3 returns to its original position, thus limiting the disengagement of the buckle 100 and preventing it from shaking after it is properly installed.

[0032] This embodiment also provides a wine box, including a box body 200 and a base 300, which are connected by the aforementioned drop-prevention anti-dislodgement buckle 100. In practical applications, similar to existing technologies, the box body 200 is provided with a mounting hole that mates with the positioning post 1, and the base 300 is provided with a corresponding mounting hole with a diameter larger than the positioning hole. The buckle 100 is inserted into the base 300 to complete the installation.

[0033] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
