Detailed implementation mode

[0020] For the convenience of those skilled in the art to understand, the present utility model will be further described below in conjunction with the embodiments and the accompanying drawings. The content mentioned in the implementation mode does not limit the present utility model.

[0021] As Figures 1 to 4 shown, a packaging box provided by the present utility model includes a first box body 1 and a second box body 2 for mating with the first box body 1. The first box body 1 and the second box body 2 are mated to form a loading cavity. One end of the first box body 1 is rotatably connected to one end of the second box body 2 via a crease line 3. A first positioning block or / and a first positioning groove 5 are provided on the inner side surface of the first box body 1. Correspondingly, a second positioning groove that is concavo-convexly adapted to the first positioning block or / and a second positioning block 6 that is concavo-convexly adapted to the first positioning groove 5 are provided on the inner side surface of the second box body 2. A snap-in insert block 8 is provided at the other end of the first box body 1, and a snap-in jack 9 is provided at the other end of the second box body 2. The snap-in insert block 8 is detachably inserted into the snap-in jack 9 so that the snap-in insert block 8 penetrates through the snap-in jack 9 and is engaged with each other.

[0022] In practical applications, the product is placed between the first box body 1 and the second box body 2. After the first box body 1 and the second box body 2 are mated, the product is loaded in the loading cavity. The first positioning block of the first box body 1 is concavo-convexly adapted to the second positioning groove of the second box body 2 or / and the first positioning groove 5 of the first box body 1 is concavo-convexly adapted to the second positioning block 6 of the second box body 2. Then, the snap-in insert block 8 is inserted into the snap-in jack 9 so that the snap-in insert block 8 is engaged with the snap-in jack 9, so that the first box body 1 and the second box body 2 can be firmly mated together, improving the stability of loading the product. The structure of the present utility model is simple. Not only through the concavo-convex cooperation of the positioning block and the positioning groove (the positioning block and the positioning groove are buckled with each other), but also through the engagement of the snap-in insert block 8 and the snap-in jack 9, the mating of the first box body 1 and the second box body 2 is firm and not easy to be opened inadvertently, improving the stability of loading the product.

[0023] In this embodiment, a first profiling loading groove 10 is formed by stretching the first box body 1 from the inner side surface to the outer side surface, and a second profiling loading groove 11 is formed by stretching the second box body 2 from the inner side surface to the outer side surface; after the first box body 1 and the second box body 2 are mated, the first profiling loading groove 10 and the second profiling loading groove 11 enclose a loading cavity. This structural design can not only load the product in a fitting manner, but also make the structure of the packaging box novel, with a beautiful and vivid appearance, and is easy to attract the attention and purchasing desire of consumers.

[0024] In this embodiment, the number of the clamping sockets 9 and the number of the clamping plugs 8 are both two. The two clamping sockets 9 are respectively arranged in one-to-one correspondence with the two clamping plugs 8. The two clamping plugs 8 are located at two end corners of the first box body 1, and the two clamping sockets 9 are located at two end corners of the second box body 2. This structural design further improves the firmness of the alignment between the first box body 1 and the second box body 2.

[0025] In this embodiment, the clamping socket 9 includes an inclined slot 12 formed in the second box body 2. The clamping plug 8 includes a chamfered surface 13 arranged at the end corner of the first box body 1, a connecting piece 14 connected to the chamfered surface 13, and a plug piece 15 connected to the connecting piece 14. The connecting piece 14 and the plug piece 15 are in a T shape. The shape of the plug piece 15 is an isosceles trapezoid. The length of the bottom side of the plug piece 15 is greater than the length of the inclined slot 12. The connecting piece 14 penetrates through the inclined slot 12, and the plug piece 15 is used for clamping with the inclined slot 12. During the process of the plug piece 15 passing through the inclined slot 12, the two isosceles sides of the plug piece 15 play a guiding role, which is beneficial to the plug piece 15 clamping with the inclined slot 12 after passing through the inclined slot 12.

[0026] In this embodiment, two fastening corners 16 are formed at the two bottom corners of the plug piece 15. The clamping socket 9 further includes two avoidance slots 17 respectively communicated with two ends of the inclined slot 12. The two avoidance slots 17 respectively provide an avoidance space for the two fastening corners 16. The included angle formed by the avoidance slot 17 and the inclined slot 12 is an obtuse angle. During the process of the plug piece 15 passing through the inclined slot 12, since the length of the bottom side of the plug piece 15 is greater than the length of the inclined slot 12, the two fastening corners 16 of the plug piece 15 will undergo recoverable elastic deformation. The avoidance slot 17 provides an avoidance space for the fastening corners 16 when they undergo elastic deformation, so that the fastening corners 16 are not easily damaged.

[0027] All the technical features in this embodiment can be freely combined according to actual needs.

[0028] The above embodiment is a preferred implementation scheme of the present utility model. In addition, the present utility model can also be implemented in other ways. Any obvious replacement without departing from the concept of the technical solution is within the protection scope of the present utility model.
