Description

Technical Field

[0001] The utility model belongs to the technical field of corrugated paper boxes, and particularly relates to a compression-resistant corrugated paper box. Background Art

[0002] Corrugated boxes are the most widely used packaging products, and their usage has always been the highest among all packaging products. They are made by die-cutting, creasing, nailing or gluing corrugated cardboard. With its superior performance and good processing performance, corrugated boxes have gradually replaced wooden boxes and other transport packaging containers, becoming the main force of transport packaging. In addition to protecting goods and facilitating warehousing and transportation, they also play a role in beautifying and promoting goods. At the same time, corrugated boxes are green and environmentally friendly products, which are conducive to environmental protection and loading and unloading transportation.

[0003] Because the hardness of corrugated paper is average, in actual use, in order to ensure the safety of corrugated boxes and avoid the lower layers of corrugated boxes being crushed when stacked, a compression-resistant structure is usually set for the corrugated boxes.

[0004] It was retrieved from the prior art that a Chinese utility model patent with authorization announcement number CN221679267U disclosed "a corrugated cardboard box with strong pressure resistance", including a cardboard box body, a first pressure-resistant structure, an inner liner box, a second pressure-resistant structure and a third pressure-resistant structure. The cardboard box body is composed of a bottom box panel and four side box panels folded together. The top of the cardboard box body is open, and two folding box covers are symmetrically provided on both sides of the top of the cardboard box body. The first pressure-resistant structure is installed at the bottom of the cardboard box body, which can greatly improve the overall pressure resistance of the corrugated cardboard box.

[0005] Although the corrugated cardboard boxes in the prior art, including those mentioned above, can improve the compressive performance to a certain extent, in actual use, because the middle parts of the two box covers are suspended in the air, it is difficult to provide stable support for the middle parts of the box covers. Although the L-shaped compressive support plates have a certain supporting effect, the horizontal parts of the two compressive support plates are still suspended in the air, and the stability is difficult to ensure. In addition, glue bonding is required to ensure that the compressive support plates are stably connected to the box covers, which is inconvenient for disassembly and maintenance.

[0006] In order to solve the above problems, the utility model provides a pressure-resistant corrugated paper box. Utility Model Content

The box cover 2 and the box body 1 can also be further bonded with adhesive tape. The utility model provides the support cage 3 and the cross-shaped plate 41, and the cross-shaped plate 41 is buckled on the top of the box body 1. The cross-shaped plate 41 can support the box cover 2 more stably to avoid the middle part of the box cover 2 collapsing, and has higher pressure resistance. There is no need to use other accessories to fix the support cage 3 and the cross-shaped plate 41, which is convenient for installation, use and disassembly and maintenance.

[0035] Preferably, by Figure 1 、 Figure 2 and Figure 4 As shown, in this embodiment, the auxiliary support plate 4 also includes: a reinforcing cross bar 42, and a plurality of reinforcing cross bars 42 are fixed at equal intervals on the bottom surface of the cross-shaped plate 41. After adopting the above scheme, the structural strength of the cross-shaped plate 41 is further improved by setting a plurality of reinforcing cross bars 42, so that the compressive performance of the corrugated cardboard box is further improved.

[0036] Preferably, by Figure 1 、 Figure 2 and Figure 4 As shown, in this embodiment, between the end of the reinforcing cross bar 42 and the bent portion 411 is a clamping groove 43 for the top end of the box body 1 to be embedded. After adopting the above design, after the cross-shaped plate 41 is buckled on the top end of the box body 1, the top end of the box body 1 is embedded in the clamping groove 43, further improving the stability of the cross-shaped plate 41 buckled on the top end of the box body 1.

The top frame 32 is located directly above the bottom frame 31, and has a positioning groove 321 on the top frame 32 for the cross-shaped plate 41 to be embedded. A plurality of connecting struts 34 are fixed between the bottom frame 31 and the top frame 32. After adopting the above design, the bottom frame 31 and the top frame 32 respectively support the box body 1 from the bottom and the top, thereby improving the stability and impact resistance of the box body 1. The connecting struts 34 stably connect the bottom frame 31 and the top frame 32, and are used to support the box cover 2 to improve the pressure resistance.

[0038] Preferably, by Figure 1-Figure 3As shown, in this embodiment, the support cage 3 also includes: inner angle support rods 33, four inner angle support rods 33 are diagonally fixed between the bottom frame 31 and the top frame 32, and the outer walls of the inner angle support rods 33 are against the inner wall of the box body 1.

[0039] It should be noted that the box body 1 of the present invention is a rectangular structure with four inner corners, so four inner corner support rods 33 are designed. The transverse cross-section of the inner corner support rods 33 is an "L"-shaped structure, which is used to support the four inner corners of the box body 1. The above scheme is only an exemplary scheme of the present invention and is not used to limit the present invention. When the box body 1 is of other shapes, the inner corner support rods 33 need to be designed according to the shape of the box body 1.
