The snap-in element further comprises a second guiding groove 8, as shown in fig. 8. The second guide grooves 8 are positioned at two sides of the second bayonet 7. Meanwhile, the buckle body further comprises a shielding part 5, and the position of the shielding part corresponds to the position of the second guide groove 8.

As shown in fig. 10 to 13, in the present utility model, the shielding portion 5 may be connected to the fixing portion 1 and extend toward the enclosing portion 2 to shield the opening of the card slot 11, or the shielding portion 5 may be connected to the enclosing portion 2 and extend toward the fixing portion 1, and the extending end may be connected to the fixing portion 1 or the enclosing portion 2 toward which the extending end is connected, or may not be connected, which is not limited by the present utility model. In other embodiments, the shielding portion 5 may be divided into two portions, namely, a first shielding portion 501 and a second shielding portion 502, where the first shielding portion 501 is connected to the fixing portion 1 and extends toward the enclosing portion 2, and the second shielding portion 502 is connected to the enclosing portion 2 and extends toward the fixing portion 1, and the first shielding portion 501 may be on the inner side or the outer side of the second shielding portion 502.

As shown in fig. 14, the shielding portion 5 has a folding area 503, and in the folding area 503, the area of the notch of the clamping groove 11 gradually decreases in a direction away from the bottom end of the enclosing portion 2. The angle of the prying tool is limited by the folding area, and the prying tool can be inserted into the clamping groove only at a limited angle, for example, 45-60 degrees, so that the prying tool is better prevented from touching the buckle body after being obliquely inserted into the clamping groove. Meanwhile, the surface of the shielding part can be provided with reinforcing ribs similar to those on the enclosing part.

In the state that the first part to be packaged and the second part are packaged, the shielding part 5 can be inserted into the second guide groove 8 to prevent the second part from moving left and right, and meanwhile, the resistance prying tool can also extend into the clamping groove from the side face.

Example 4

Taking a packaging box as an example, as shown in fig. 7, 8 and 9, a buckle body is connected to the inner wall of the box body 10/side plate of the box cover 11, and a clamping piece is connected to the inner wall of the corresponding side plate of the box cover 11/box body 10 or a clamping structure is directly prepared. The number of the buckle body and the clamping piece/clamping structure can be one, or can be two, three or four, and the buckle body and the clamping piece/clamping structure are arranged on different surfaces of the box body.

As shown in fig. 6, the case is formed by compounding a plurality of paper boards, and at least part of the periphery of the engaging member is covered by the paper boards. The fixing part is fixedly arranged on the side plate of the box body/box cover in an adhesive, clamping or embedding way.

When the box cover is covered on the box body, the buckle body 3 on the side plate/box body of the box cover is clamped with the first bayonet 111 or the second bayonet 7 on the side plate/box body of the box cover, and the shielding part 5 on the side plate/box body of the box cover is inserted into the first guide groove 112 or the second guide groove 8 of the box body/box cover for guiding and limiting. A tear 12 is provided in the area where the fixing portion is installed, and a user can break the case body by tearing the tear 12, thereby opening the case cover to take out the product inside.

Through the arrangement, under the condition that a counterfeiter prizes by external force of tools such as a steel ruler, the side plate of the cover body has strong perforable deformation capacity because of the embedded metal sheet, the deformation is very small, the packaging box is difficult to prize under the condition that the shell does not leave marks, and the packaging box is damaged by forced plugging in to damage the tearing opening. Meanwhile, the guide grooves on the side plates of the cover body are inserted into the shielding parts on the buckle body, and meanwhile, the two sides on the side plates of the cover body are accommodated in the box body to form a cavity, so that the moving amount of the cover body is very small. Meanwhile, if an lawbreaker uses an iron wire to jack in from a gap on one side of the back of the box body and the side plate, the other side box cover is deformed due to the elastic pressing part on the buckle body, so that the iron wire cannot be pried away from the clamping piece. Meanwhile, because of the improvement of the shape and the matching of the metal iron sheet on the box cover, the buckle cannot be damaged and cut no matter what the box cover is pulled left and right. The packaging box can not be opened under the condition that the structures such as the cover body and the anti-counterfeiting buckle are not damaged or the shell is permanently deformed due to external force. The technology can well protect the packaging box and prevent prying and damage.
