[0033] The following examples, with reference to the accompanying drawings, illustrate preferred practices.

[0034] Case 1;

[0035] exist Figure 1 In the middle, the main buckle 2 is a square iron sheet, which can be made of stainless steel, manganese steel, or black iron sheet, etc. The thickness of the iron sheet is preferably 0.6 mm. The iron sheet is provided with a cutting line, which divides the first mounting part 21. The first mounting part is divided into a first bending part 22 and a second bending part 23 on both sides. The first mounting part also has protruding teeth 211, which can also be spring pieces, mainly for biting.

[0036] The spring clips, countersunk teeth, and engagement holes mentioned in the article are all formed by stamping iron sheets.

[0037] Figure 2 In section 3.4, the first bending part 22 and the second bending part 23 are formed by bending to form a receiving part, which is an enclosed structure.

[0038] Specifically, the first mounting part 21 of the main buckle is provided with a first bending part 22 and a second bending part 23 on both sides. The first bending part 22 is formed by the material on both sides of the main buckle extending away from the first mounting part 21, and the second bending part 23 is formed by the end of the first bending part 22 extending towards the central axis of the main buckle 2, forming a similar enclosing structure.

[0039] Figure 1 , 3 In section 4, the first mounting part, the first bending part, and the second bending part are integrated, which is achieved through... Figure 1 Formed by bending iron sheets.

[0040] Figure 3 , 4 In the middle, a gap is provided between the two second bends. The gap can be set between 0.1-15 mm. Preferably, it is 1-6 mm, and the larger the gap, the more material is saved.

[0041] Figure 5 In the middle, the fastener 3 is composed of the second mounting part 31 and the receiving part, and the main fastener is provided with an interlocking mechanism;

[0042] The fastener 3 consists of a second mounting part and an insert part. The second mounting part and the insert part are integrated, and the insert part is provided with a check valve structure.

[0043] The anti-return structure is a toothed or spring-loaded piece, a step, and an engagement hole. The spring-loaded piece is formed by die-cutting and folding back the material from the edge of the sheet. The toothed piece is formed by protruding parts on the sheet. The engagement structure is a toothed or spring-loaded piece, a step, and an engagement hole.

[0044] Figure 7 In this packaging box, the box body and the box lid are combined. The main buckle 2 is fixed to the box body and is connected to the box body by adhesive through the first mounting part 21. The second mounting part of the buckle 3 is fixed to the box lid by adhesive. Figure 7 This anti-counterfeiting structure can be used on boxes that open from the top, such as book boxes, hinged boxes, etc.

[0045] When the lid is fastened to the box body, the insert part 32 of the fastener 3 is inserted into the receiving part of the main fastener 2. The reverse teeth on the insert part 32 engage with the spring piece in the receiving part, sealing the packaging box and preventing it from being opened illegally.

[0046] Figure 1 , 3 In the first mounting part 21, auxiliary mounting parts 212 are provided on both sides, and the auxiliary mounting parts 212 are formed by extending material from the upper and lower sides of the first mounting part 21. Alternatively, only the upper two sides or the lower two sides may extend.

[0047] The main purpose of this component is to increase the mounting area, making the anti-counterfeiting buckle more secure.

[0048] Figure 3 In the middle, the lower edge of the second bending part 23 is provided with an interlocking structure 213. The advantage of this setting is that the interlocking structure 213 folds inward to avoid the main buckle iron piece from scratching the hand.

[0049] Figure 4 In the design, the insert portion 32 of the fastener 3 is provided with an engaging portion 321, which is a spring-loaded piece formed by folding back the lower edge of the insert portion. The advantage of this design is that the edge of the fastener will not hurt the hand after bending.

[0050] The advantage of this design is that the insert section is thicker, the dimensions are more stable, and it is not easily deformed when damaged.

[0051] Figure 4 In this process, the thickness of the metal sheet of the main buckle is set between 0.3 and 0.8 mm, preferably between 0.6 and 0.8 mm, and the surface of the main buckle is provided with a paint layer, which can be applied by spraying or rolling.

[0052] The advantage of having a paint layer on the surface of the main buckle is that it prevents injury to hands when opening the packaging box.

[0053] Figure 4 In the middle, the upper part of the main buckle 2 is provided with an inlet section, and the front end of the inlet section extends away from the first mounting section. This is mainly to facilitate the insertion of the buckle 3.

[0054] Figure 6 In the main buckle, an inlet part 25 is provided at the upper part, and the insert part 32 of the buckle piece 3 is inserted into the receiving part of the main buckle. The receiving part is an enclosed structure with a second reverse tooth 215 inside. After the insert part 32 is inserted, the anti-return structure 321 provided on it engages with the second reverse tooth 215, making it impossible for the two to separate effectively, thus achieving the purpose of anti-counterfeiting.

[0055] Case 2;

[0056] Figure 8 In section 9, the material on both sides of the insert portion 32 is folded back to form a stepped portion 323, and a check valve structure 3231 is provided on the stepped portion. The check valve structure 3231 is a toothed reciprocating tooth, a spring, or an engaging hole.

[0057] Furthermore, since both the main buckle and the buckle plate of the anti-counterfeiting buckle are made of metal materials, preferably iron sheets such as black iron, manganese steel sheets, and stainless steel sheets, the melting point of these metal materials is over 1000 degrees Celsius. Moreover, these materials undergo processes such as avoidance and surface oiling during manufacturing to ensure they are not harmful to the hands. Therefore, they cannot be damaged by blowing air or heating, thus achieving the function of preventing counterfeiting and unauthorized opening.

[0058] To further understand the features and details of this utility model, please refer to the following detailed description and drawings of this utility model. However, the drawings are provided for reference and illustration only and are not intended to limit this utility model.

[0059] As described above, those skilled in the art can make various other corresponding changes and modifications based on the technical solution and concept of this utility model, and all such adjustments, changes, and modifications should fall within the protection scope of the claims of this utility model.
