Description

Technical Field

[0001] The utility model relates to the technical field of cartons, and more particularly to a freight carton which is convenient for stacking. Background Art

[0002] Announcement No. CN219750374U proposes a carton that is easy to stack, which proposes a support component that is set up to ensure that when in use, the corner support strips can be used to support the corners of the box. In addition, the bottom plate is supported at the bottom of the box, which can make the box more firm and stable, not easy to be crushed, and convenient to stack together. In addition, the plug-in cooperation between the guide block and the limit slot is also convenient for guiding operations, further ensuring that the stacking position of the box is correct, and side edges are not likely to appear, making stacking more convenient, and solving the problem of limited pressure resistance of conventional cartons. When the weight in the carton is heavy, it is very easy to crush the carton under the weight, and after the collapse, it may also cause the carton above the collapsed carton to fall over, posing certain safety hazards and bringing inconvenience to the stacking operation.

[0003] In the above-mentioned setting, in order to ensure the stability of the stacking between the upper and lower cartons, the guide plug is inserted into the limit slot. That is, when stacking, the cartons are placed from top to bottom. When unloading, since the guide plug is inserted into the limit slot, the carton needs to be lifted up before it can be removed. For heavier cartons, the general habit is to pull out the carton directly, which is inconvenient for those who need to lift it. Utility Model Content

By arranging the connecting plate, the T-shaped plug block, the first spring, the screw rod and the triangular plate, the connecting plate can be connected to the positioning plate, so as to facilitate the stacking of the upper and lower boxes.

[0007] The solution is further that a spherical groove is provided on the lower surface of the connecting plate, and a movable ball is rotatably connected to the inner wall of the spherical groove; the positioning assembly includes a T-shaped positioning block, a T-shaped groove is provided on the side of the positioning plate, the surface of the T-shaped positioning block overlaps the inner wall of the T-shaped groove, the upper and lower surfaces of the T-shaped positioning block are both arc-shaped, and a second spring is fixedly connected to the opposite surface of the T-shaped positioning block and the T-slot, a connecting groove is provided on the inner side wall of the angle strip, and the surface of the T-shaped positioning block overlaps the inner wall of the connecting groove, a groove is provided on the upper surface of the positioning plate, and a handle is rotatably connected to the inner wall of the groove.

[0008] A further solution is that there are four corner bars, which are arranged in a rectangular array at the four corners of the upper surface of the base. The inner bottom wall of the square cavity is fixedly connected with a limit block for limiting the position of the triangle plate. The setting of the limit block can limit the left and right moving distance of the triangle plate, making it convenient for the staff to turn the screw rod to determine the position of the triangle plate.

[0009] Technical effects and advantages of the utility model:

[0010] 1. The freight carton that is easy to stack, when the boxes are stacked, the connecting plate is placed in the placement groove on the positioning plate, and the screw rod is turned. Under the limit of the square cavity, the triangular plate moves, and the triangular plate pushes the arc surface of the T-shaped plug. Under the extrusion of the triangular plate, the T-shaped plug is inserted into the positioning groove, thereby completing the stacking between the upper and lower boxes. The upper and lower boxes are connected and fixed by the T-shaped plug, which can avoid relative displacement between the upper and lower boxes. At the same time, when unloading the box, the screw rod can be reversed, and the screw rod drives the triangular plate away from the T-shaped plug. Under the elastic force of the first spring, the T-shaped plug is disengaged from the positioning groove, and the box can be directly pulled to complete the separation, which is more convenient than the method of lifting the box upward to complete the separation.

[0011] 2. The freight carton which is easy to stack is provided with a moving ball. When the moving ball overlaps with the ground, the box can be pushed to move. The rotation of the moving ball facilitates the pushing of the box. The box is placed on the base and then covered with a positioning plate. The arc surface of the T-shaped positioning block is forced to be accommodated in the T-shaped groove, and the second spring is squeezed. When the T-shaped positioning block moves to the connecting groove, the elastic force of the second spring pushes the T-shaped positioning block to be inserted into the connecting groove. The positioning plate is pulled by the handle, and the upper arc surface of the T-shaped positioning block is forced to be accommodated in the T-shaped groove. The positioning plate can be removed to facilitate the taking and placing of the box. BRIEF DESCRIPTION OF THE DRAWINGS
