[0012] (III) Beneficial Effects

[0013] This utility model provides a corrugated cardboard box that is easy to stack. It has the following beneficial effects:

[0014] (i) By setting a limiting plate, the side panels and the mating cover can be bent up when the top of the box needs to be closed, and cooperate with the box to form a closed space to accommodate items. When the side panel is bent, the side panel drives the connecting plate to slide in the slide groove, and makes the limiting plate perpendicular to the top plane of the box. When other corrugated boxes need to be stacked on top of the corrugated box, the limiting plate can limit the corrugated box that is horizontally above, preventing it from being misaligned when stacked.

[0015] (II) By setting up triangular support plates, when the inside of the corrugated cardboard box contains small items, the sliding cover plate is moved to a perpendicular state with the side wall of the box, which can enhance the strength of the side wall of the box and improve the compression resistance of the box. When stacking corrugated cardboard boxes, the limiting plate in the upper cardboard box slides down along the slot and inserts into the vertical limiting groove of the lower cardboard box, which can limit the vertical position of the upper corrugated cardboard box and enhance the structural stability when the boxes are stacked. During this process, the limiting block at the top of the sliding cover plate in the lower corrugated cardboard box can be locked in the horizontal limiting groove at the bottom of the upper corrugated cardboard box, realizing the stable stacking of corrugated cardboard boxes and further enhancing the structural stability when the boxes are stacked.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example: Please refer to Figure 1-4 This utility model provides a technical solution: a corrugated cardboard box that is easy to stack, including a box body 1, with side panels 2 symmetrically crimped to the top of the box body 1, and further including:

[0023] The top of the fitting cover plate 3 is fixedly connected to the limiting block 11. The side wall of the box body 1 is glued with a triangular support plate 4, which is linearly arranged along the inner wall of the box body 1. The outer side of the triangular support plate 4 is slidably connected to the limiting insert plate 5. The outer side of the side plate 2 is fixedly connected to the connecting plate 6, and the outer side of the connecting plate 6 is fixedly connected to the limiting plate 7. There are two fitting cover plates 3, which are symmetrically indented and connected to the top of the box body 1. When it is necessary to close the top of the box body 1, the side plate 2 and the fitting cover plate 3 can be bent up to cooperate with the box body 1 to form a closed space to accommodate items. When the side plate 2 is bent, the side plate 2 drives the connecting plate 6 to slide in the slide groove 8, and makes the limiting plate 7 perpendicular to the top plane of the box body 1. When it is necessary to stack other corrugated cardboard boxes on top of the corrugated cardboard box, the limiting plate 7 can limit the corrugated cardboard boxes that are horizontally upward to prevent them from being misaligned when stacked.

[0024] Limiting blocks 11 are symmetrically arranged along both sides of the mating cover plate 3. A horizontal limiting groove 10 is symmetrically opened at the bottom of the box body 1. The bottom of the limiting insert plate 5 is inserted into the inner side of the box body 1 via a slot 9, and the slot 9 is located at the bottom of the box body 1. The limiting insert plate 5 is symmetrically arranged along the inner side of the box body 1. A vertical limiting groove 12 is opened in the wall of the mating cover plate 3. The outer side of the connecting plate 6 is slidably connected to the side wall of the box body 1 via a sliding groove 8, and the sliding groove 8 is located in the side wall of the box body 1. The inner side wall of the box body 1 is bonded to the side edge of the mating cover plate 3, allowing the triangular support plate 4 to rotate relative to the inner wall of the box body 1 along its edge. When the inside of the box body 1 contains small items... When the cover plate 3 is moved to a perpendicular position with the side wall of the box body 1, it can enhance the strength of the side wall of the box body 1 and improve the compression resistance of the box body 1. When stacking corrugated boxes, the limiting plate 5 located in the upper box is slid down along the slot 9 and inserted into the vertical limiting slot 12 of the lower box, which can limit the corrugated box that is vertically above, thus enhancing the structural stability when the boxes are stacked. During this process, the limiting block 11 at the top of the cover plate 3 in the lower corrugated box can be locked in the horizontal limiting slot 10 at the bottom of the upper corrugated box, realizing the stable stacking of corrugated boxes and further enhancing the structural stability when the boxes are stacked.

[0025] Working principle: This easy-to-stack corrugated cardboard box is mainly composed of the box body 1, side panels 2, hinged cover 3, triangular support plate 4, limiting insert plate 5, connecting plate 6, and limiting plate 7. All components are corrugated cardboard structures, and the various parts work together to achieve the functions of easy stacking and protection of the contents.

[0026] When in use, when the top of the box 1 needs to be closed, the side panel 2 and the mating cover 3 can be bent up to cooperate with the box 1 to form a closed space to accommodate items. When the side panel 2 is bent, the side panel 2 drives the connecting plate 6 to slide in the slide groove 8, and makes the limiting plate 7 perpendicular to the top plane of the box 1. When other corrugated cardboard boxes need to be stacked on top of the corrugated cardboard box, the limiting plate 7 can limit the corrugated cardboard box that is horizontally upward to prevent it from being misaligned when stacked.

[0027] The inner sidewall of the box 1 is bonded to the side edge of the mating cover plate 3, allowing the triangular support plate 4 to rotate relative to the inner wall of the box 1 along its edge. When the box 1 contains small items, the mating cover plate 3 is moved to a perpendicular position with the sidewall of the box 1, which can enhance the strength of the sidewall of the box 1 and improve the compression resistance of the box 1. When stacking corrugated boxes, the limiting insert plate 5 in the upper box is slid down along the slot 9 and inserted into the vertical limiting groove 12 of the lower box, which can limit the corrugated box that is vertically above, enhancing the structural stability when the boxes are stacked. During this process, the limiting block 11 at the top of the mating cover plate 3 in the lower corrugated box can be locked in the horizontal limiting groove 10 at the bottom of the upper corrugated box, achieving stable stacking of corrugated boxes and further enhancing the structural stability when the boxes are stacked.
