Description

Technical Field

[0001] The utility model relates to the technical field of packaging paper boxes, in particular to a packaging paper box which is easy to stack. Background Art

[0002] With the continuous improvement of people's living standards and environmental awareness, more and more paper boxes are appearing in our lives instead of plastic packaging. By cutting corrugated paper into specific shapes and then folding it and fixing it with transparent tape, the paper boxes not only have functions such as multiple use and recyclability, but also can be printed with patterns and text on the top, which not only increases the aesthetics of the paper boxes but also displays and promotes the items inside. Existing packaging paper boxes are not easy to position when stacked, and are prone to displacement and misalignment during the stacking process, resulting in the packaging paper boxes being not very stable when stacked. When the stack is too high, the packaging paper boxes are prone to collapse, causing damage to the items inside the paper boxes, affecting normal use, and reducing the practicality of the device. Therefore, a packaging paper box that is easy to stack is provided to solve the above problems. Utility Model Content

[0003] The purpose of the present invention is to provide a packaging paper box that is easy to stack, so as to solve the problem raised in the above background technology that the existing packaging paper boxes are not easy to position when stacking, and are very likely to be offset and misplaced during the stacking process, resulting in the packaging paper boxes being not very stable when stacked. When the stacking is too high, the packaging paper boxes are likely to collapse, causing damage to the items inside the paper box, affecting normal use, and reducing the practicality of the device.

[0004] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0006] The first, second, third and fourth corner guard plates are arranged inside the device so that there will be no collision between adjacent packaging paper box bodies. The user pushes the first push block to slide along the first slide groove, and the first push block drives the first limit block to move so that the first limit block enters the interior of the first limit groove, completing the longitudinal limit work of multiple packaging paper box bodies to ensure that after multiple packaging paper box bodies are stacked, there will be no longitudinal displacement. The user pushes the second push block to move along the second slide groove, and the second push block drives the L-shaped limit plate to move so that the L-shaped limit plate enters the interior of the second limit groove, completing the lateral displacement restriction of the left packaging paper box body and the right packaging paper box body, ensuring that there is no slippage between the stacked adjacent left and right packaging paper box bodies. Compared with conventional packaging paper box bodies, no positioning mechanism is provided. The stacked packaging paper box bodies are not easy to overturn, ensuring that the stored items inside the packaging paper box bodies are protected from damage. The structural stability of the entire positioning mechanism is good, not easy to deform, does not affect the normal use of the packaging paper box body, is easy to install and splice, and improves the practicality of the device.

[0007] As a preferred solution of the present invention, a first sliding groove is provided inside the third corner guard plate, a first push block is slidably connected inside the first sliding groove, and the first push block is fixedly connected to the first limit block.

[0008] The user pushes the first pushing block to slide along the first sliding groove, and the first pushing block drives the first limiting block to move.

[0009] As a preferred solution of the present invention, a second corner guard is symmetrically fixedly connected to the outside of the packaging paper box body and located on one side of the first corner guard.

[0010] The arrangement of the first corner guard plate, the second corner guard plate, the third corner guard plate and the fourth corner guard plate inside the device prevents adjacent packaging paper box bodies from colliding with each other.

[0011] As a preferred solution of the present invention, a second sliding groove is provided inside the fourth corner guard plate, a second push block is slidably connected inside the second sliding groove, and the second push block is fixedly connected to the L-shaped limiting plate.

[0012] The user pushes the second push block to move along the second sliding groove, and the second push block drives the L-shaped limiting plate to move.

[0013] As a preferred solution of the present invention, the bottom of the L-shaped limiting plate is equidistantly fixedly connected with a second limiting block, and the interior of the second square groove is equidistantly fixedly connected with a third limiting block used in conjunction with the second limiting block.

[0014] It is convenient to limit the L-shaped limiting plate and prevent the L-shaped limiting plate from shaking inside the second square groove.

[0015] As a preferred solution of the present invention, the first corner guard plate, the second corner guard plate, the third corner guard plate and the fourth corner guard plate are all L-shaped structures.

[0016] This prevents adjacent packaging carton bodies from colliding with each other, effectively protecting the packaging carton bodies.

[0017] The beneficial effect achieved by the present invention is that: through the arrangement of the first limit block, the first limit groove and the L-shaped limit plate, the first pushing block can be pushed to drive the first limit block to move, so that the first limit block enters the interior of the first limit groove, and the second pushing block is pushed to move the L-shaped limit plate to enter the interior of the second limit groove, thereby completing the limiting work after multiple packaging paper box bodies are stacked. Compared with conventional packaging paper box bodies that do not have a positioning mechanism, the stacked packaging paper box bodies are not easy to overturn, ensuring that the stored items inside the packaging paper box bodies are protected from damage. The structural stability of the entire positioning mechanism is good, not easy to deform, and does not affect the normal use of the packaging paper box bodies, thereby improving the practicality of the device.
