It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.

Example 1

As shown in fig. 2, based on the locking structure of the packing box, the packing box comprises a box bottom 1, two long side walls 2 symmetrically arranged at the upper and lower sides of the box bottom 1, a box cover 3 arranged on the long side walls 2, two short side walls 4 symmetrically arranged at the left and right sides of the box bottom 1, and folding parts 5 connected to any two adjacent long side walls 2 and short side walls 4 at the same time, and the packing box is provided with the locking structure; the lock catch structure consists of a buckling piece 6, a lock head 7 and a lock hole 8.

The structure of the packing box, such as the box bottom, the long side wall, the box cover, the short side wall and the folding part, is the prior art, and the arrangement and the use can be completed by a person skilled in the art without creative labor. The box cover can be arranged according to actual requirements, such as only being arranged on any one long side wall, respectively arranging two symmetrical box covers on the two long side walls, respectively arranging two asymmetrical box covers on the two long side walls, and the like.

In order to facilitate the buckling of the box cover, the upper edge or the lower edge of the box cover is respectively provided with an inserting strip, and the short side wall is provided with a slot matched with the inserting strip. In order to improve the bearing capacity of the edge of the paper box, adhesive strips can be arranged between the short side walls and the box bottom and between the long side walls and the folding parts, and the adhesive strips can be turned and adhered to the box bottom and the long side walls when the paper box is folded.

The fastening pieces 6 are arranged on the upper side or the lower side of the folding part 5, and only one fastening piece 6 is arranged on one folding part 5.

The lock head 7 is arranged on the upper side or the lower side of the buckling piece 6, and the lock hole 8 is arranged on the upper edge and the lower edge of the box bottom 1; the size and the position of the lock hole 8 and the lock head 7 are matched with each other.

The buckling piece and the lock head part are obtained after the part is cut out and is reserved and transformed in the prior art, so the material cost of a product cannot be increased due to the arrangement of the buckling piece, the production amount of leftover materials in the production process of the product is reduced, resources are utilized more reasonably, the utilization rate of the resources is effectively improved, and the requirements of enterprises are met more.

When the carton is used, glue is smeared on the shadow part in fig. 4, then the part smeared with the glue is overturned and pasted on the bottom and the long side wall of the carton, the long side wall and the short side wall are folded upwards to form the carton, after the carton is formed, the locking head is inserted into the locking hole by folding the buckling pieces to complete the fixation of the carton so as to obtain the structure shown in fig. 6, and finally, after goods are loaded, the two box covers are overturned relatively, and the inserting strips on the box covers are inserted into the inserting grooves on the short side wall so as to obtain the structure shown in fig. 7.

Due to the fact that the lock catch structure is arranged, when the long side wall or the short side wall of the paper box is pulled/pushed outwards, deformation of the folding portion is hindered by the buckling pieces, and therefore the folding portion cannot be unfolded directly, the paper box is prevented from being scattered when stressed, bearing capacity and stress capacity of the paper box are greatly improved, and stability of the paper box during use is improved better.

In addition, the main material of the present application is paper, but other materials such as PVC, corrugated paper, etc. can be used, so that products made of other materials and having the same structure as the present application should also be included in the protection scope of the present application.
