Plug-in strip type packing box

Abstract

The invention relates to a plug-in strip type packing box; a main box plate is connected with a lateral box plate through an L-shaped locking bar on which a positioning nail embedded in the main box plate and the lateral box plate are punched; at least one edge of external walls of the main box plate and the lateral box plate is provided with a locking piece; a locking seam or a locking button isarranged on the L-shaped locking bar; and the locking piece is in an insertion and tight locking condition with the locking seam or the locking button so as to cause the connection between the two adjacent box plates to be more fastened. By using a dual-locking way between the L-shaped locking bar and the box plates and between the L-shaped locking bar and the locking piece, the plug-in strip typepacking box facilitates the connection of the packing box to be firm, safe and reliable, and the installation can be convenient and fast; the box plates can be transported to spot for assembly, thereby saving transportation cost, improving working efficiency and causing the disassembly to be more convenient, in addition, the box plates can be repeatedly used, thereby saving timber and lowering cost.

Description

technical field [0001] The invention relates to a packing box, in particular to an insert-type packing box. Background technique [0002] The existing packaging boxes are generally made by fixing the box boards with nails. The assembly is cumbersome and not firm. It is easy to cause damage during transportation and affects the safety of the goods. Moreover, the traditional packaging boxes are inconvenient to disassemble and cannot be reused, which wastes wood. Rough and not beautiful. For example, the patent No. ZL03259099.7 discloses a fast packing box, the main box board and the side box board are connected by "L" shaped corner strips, and the corner strips are provided with positioning nails embedded in the main box board and side box boards. , the use of this fixing method can make the packaging box reused, save wood, and facilitate assembly and disassembly. The purpose of locking and positioning is not strong enough. Once the positioning nail is displaced or deformed,...
