The utility model adopts the technical proposal that: the cable packing box with handle is made of corrugated paper board and features that two handle planes and two buckle planes extending upwards from the upper end of the box body are connected to form handle structure. In the carton made by the prior art, the locking structures at the two ends above the carton body are unlocked to open the carton body, and the opening direction of the carton body is only the upper direction, so the carton is inconvenient to use in a plurality of specific environments, such as a portable state and a carton opening, picking and placing operation.

SUMMERY OF THE UTILITY MODEL

The existing handle paper box is inconvenient to use. Based on the problem, the utility model provides a portable side opening carton cut-parts, one of them side can still be opened under portable state to the carton of folding formation, facilitates the use.

In order to realize the purpose of the invention, the utility model adopts the following technical scheme: a portable paper box cutting piece with an opening at the side end comprises a bottom plate, a left side plate, a right side plate and a rear side plate, wherein the left side, the right side and the upper side of the bottom plate are respectively connected with the left side plate, the right side plate and the rear side plate; the upper cover structure comprises a left upper cover plate connected to the left side edge of the left side plate, the left side edge of the left upper cover plate is sequentially connected with a left handle plate and a right handle plate, and the left side edge of the right handle plate is connected with the right upper cover plate; the left side of the left handle plate is taken as a symmetry axis, the left handle plate and the right handle plate are symmetrically arranged, and the left upper cover plate and the right upper cover plate are symmetrically arranged; the upper cover structure is provided with a buckling structure matched with the rear buckling hole; the left side board is gone up before being equipped with of the lower side downwardly extending of left side upper cover board, and the right side board is gone up before being equipped with of the lower side downwardly extending of right side upper cover board, and the left side board before being equipped with of the lower side downwardly extending of left side board, the right side board before being equipped with of the lower side downwardly extending of right side board, and the lower board before being equipped with of the lower side downwardly extending of bottom plate, preceding left side board, preceding right side board and preceding hypoplastron constitute preceding lateral wall locking structure.

The portable side opening carton cut-parts that this technical scheme designed, with the difference of traditional handle box, are provided with independent bottom plate, the lateral wall in four directions is connected with the side of bottom plate, the last side of rear side board wherein is connected with back buckling board, is equipped with back buckling hole on the back buckling board. The rear buckling plate is an openable component. The upper cover structure in this scheme has adopted bilateral symmetry's design, has included left upper cover plate and right upper cover plate, and left and right upper cover plate can the amalgamation form the shape of upper cover. The left and right upper cover plates are connected with a left handle plate and a right handle plate, the left and right handle plates are used for designing handle holes so as to be convenient for carrying, and are bent upwards and attached to each other when folded, only constitute a handle part and do not constitute the shape of the upper cover of the carton. The upper cover structure only retains a buckling structure matched with the buckling hole of the rear side plate, so that the rear buckling hole on the rear buckling plate is matched with the rear buckling hole for use. For the fixing problem of the upper cover structure, the scheme is realized by adopting a mode of locking the front side wall. The left side board is gone up before being equipped with of the lower side downwardly extending of left side upper cover board, right side board is gone up before being equipped with of the lower side downwardly extending of right side upper cover board, left side board before being equipped with of the lower side downwardly extending of left side board, right side board before being equipped with of the lower side downwardly extending of right side board, lower side downwardly extending's of bottom plate lower board before being equipped with, these five downwardly extending's part has constituted the preceding lateral wall of carton, can borrow the locking of lateral wall before the locking bottom structure realization that current carton is commonly used, thereby lock the upper cover in the front side. And the locking of the rear side of the upper cover is realized by matching the rear buckling hole with the buckling structure on the upper cover. Therefore, the upper cover forms a stable fixing structure to ensure the shape fixation of the box body. After the folding box is folded, even if the rear buckling hole is opened, the upper cover is still fixed by the front side wall locking structure and cannot be easily scattered.

Preferably, a left closed folding plate is connected between the left side edge of the rear side plate and the upper side edge of the left side plate, and a plurality of crease lines are arranged on the left closed folding plate; the intersection point of the left side edge of the rear side plate and the upper side edge of the left side plate is taken as an original point, and the crease line is arranged along the ray direction passing through the original point; and a right closed folding plate is connected between the right side edge of the rear side plate and the upper side edge of the right side plate. Under the state that does not have left, right closed folding plate, can form the gap between the rear side board after folding into the case and left, right side board, be unfavorable for placing small-size article in the box body. The left and right closed folding plates of this scheme design, the left and right side of posterior lateral plate is connected with the last side of left lateral plate, the last side of right lateral plate respectively, has eliminated the gap behind the folding forming, helps enlarging the suitability that the box body held the dress article. The crease lines designed on the left and right closed folding plates are used for folding the left and right closed folding plates in the box body when the box is folded, so as to reduce the interference with the objects held in the box body. The number of crease lines can be more or less, more the volume after left and right closed folding board is folding is less, more be favorable to the space utilization of box body inside, but also should consider cut-parts fold into convenience and the high efficiency requirement of case, also receive cut-parts material thickness's physical limitation simultaneously, can not infinitely increase. Finally, the selection can be carried out by the person skilled in the art according to the actual needs.
