Description

Technical Field

[0001] The invention relates to the field of foam boxes, and in particular to a foam box structure. Background Art

[0002] Foam boxes are commonly used packaging products for shipping goods. However, foam boxes are light in weight and are prone to tipping over when stacked. In addition, their verticality cannot be controlled during stacking, causing the foam boxes to overturn after being stacked to a certain height, thereby reducing stacking efficiency.

[0003] For this purpose, there is a foam box that is easy to stack, such as patent announcement number CN217754609U. While solving the above problems, it has the following defects, such as: its magnet layer and metal layer are suspended on the bottom wall of the box body or the top surface of the box cover, and cannot effectively improve the overall pressure-bearing performance of the bottom wall of the box body and the box cover. At the same time, the magnet layer and the metal layer are both bonded in the corresponding grooves, and the stability of the two cannot be effectively guaranteed, and the above components are prone to slipping out of the grooves. Summary of the invention

[0004] The purpose of the present invention is to provide a foam box structure.

[0005] The technical problem of the present invention is mainly solved by the following technical solutions:

[0019] The following are examples and the attached Figure 1-2 , the technical solution of the present invention is further specifically described.

[0020] A foam box structure, comprising a box body 1 and a box cover 2:

[0021] A metal plate I3 is longitudinally arranged in the bottom wall of the box body 1, wherein a screw hole I is opened in the middle of the metal plate I3, and a stud 4 screwed to the screw hole I is arranged at the bottom of the box body 1, and a fixing channel 5 is arranged on the bottom end surface of the stud 4, wherein a screw rod 6 is screwed in the fixing channel 5, and the screw rod 6 is connected to a magnetic block 7 on the bottom end surface of the stud 4, and the cross section of the magnetic block 7 is a polygonal structure;

[0022] A metal plate II8 is horizontally arranged in the side wall of the box cover 2, wherein a screw hole II corresponding to the screw hole I is opened in the middle of the metal plate II8, and a screw tube 9 screwed to the screw hole II is arranged on the top of the box cover 2, and the inner diameter of the screw tube 9 is adapted to the size of the magnetic block 7.

[0023] In this embodiment, when two sets of box bodies 1 and box covers 2 are stacked, the magnetic blocks 7 can be embedded in the corresponding openings of the spiral tubes 9 .

[0024] In this embodiment, the metal plate I3 and the metal plate II8 are vertically intersected with each other, and the intersection point between the two is located in the middle of the box body 1 and the box cover 2.

[0025] In this embodiment, a mounting hole I for accommodating the stud 4 to pass through is provided on the bottom end surface of the box body 1, wherein the bottom end of the stud 4 is flush with the bottom end surface of the box body 1.

[0026] In this embodiment, a mounting hole II for accommodating the screw tube 9 is provided on the top surface of the box cover 2 , wherein the top end of the screw tube 9 is flush with the top surface of the box cover 2 .

[0027] In this embodiment, a mounting channel I for the metal plate I3 to pass through is provided on the bottom wall of the box body 1, wherein the metal plate I3 is bonded and fixed to the mounting channel I. At the same time, the stud 4 passes through the mounting hole I and is screwed to the screw hole I, so that the metal plate I3 is hung thereon, thereby effectively preventing the metal plate I3 from slipping out of the mounting channel I, so as to strengthen the stability of the metal plate I3 on ​​the bottom wall of the box body 1.

[0028] In this embodiment, a mounting channel II for the metal plate II8 to pass through is provided on the side wall of the box cover 2, wherein the metal plate II8 is bonded and fixed to the mounting channel II. At the same time, a screw tube 9 is passed through the mounting hole II and is screwed to the screw hole II, so that the metal plate II8 is hung thereon, thereby effectively preventing the metal plate II8 from slipping out of the mounting channel II, thereby strengthening the stability of the metal plate II8 on the bottom wall of the box cover 2.

[0029] The method of using the present invention is as follows: the strength of the corresponding box body 1 and the box cover 2 is strengthened by the metal plate I3 and the metal plate II8. When the upper and lower groups of foam boxes are stacked, the vertically crossed metal plates I3 and the metal plates II8 can support and fix the upper foam box, preventing gravity from acting only on the suspended area of ​​the box cover 2 and the suspended area of ​​the bottom wall of the box body 1, so that the side wall of the box body 1 can be used to share the above gravity, thereby improving the pressure bearing capacity of the bottom wall of the box body 1 and the box cover 2. At the same time, the corresponding metal plates are hung by the studs 4 and the screw tubes 9. The metal plate I3 and the metal plate II8 can effectively prevent it from sliding out from the bottom wall of the box body 1 and the box cover 2, so as to improve its installation stability; and when multiple groups of foam boxes are stacked, the magnetic block 7 is embedded in the corresponding screw tube 9 for magnetic connection, which can effectively prevent the two groups of foam boxes from separating, and secondly, it can also prevent the two groups of foam boxes from being horizontally misaligned. When a foam box needs to be placed on the ground, in order to prevent the magnetic block 7 from lifting it up and suspending it in the air or tilting it, the magnetic block 7 can be rotated to drive the screw 6 to separate from the fixed channel 5.

[0030] The present invention is described in detail above, but the contents are only preferred embodiments of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of application of the present invention should still fall within the scope of the patent coverage of the present invention.
