Description

Technical Field

[0001] This utility model relates to the field of transportation technology, and in particular to a logistics container. Background Technology

[0002] In the field of modern logistics transportation and storage, logistics containers, as core tools for ensuring the safe flow of goods and improving logistics efficiency, directly affect the integrity of transported goods and the stability of the logistics system through their structural reliability. This is especially true in the transportation of high-precision, high-value goods such as electronic and communication equipment, medical and biological agents, and aerospace and military equipment, where extremely high demands are placed on the structural strength of logistics containers. However, existing logistics containers suffer from significant deficiencies in structural strength. Specifically, the main body of the container struggles to provide effective and stable support for the goods it carries. When subjected to external forces such as compression or collisions, insufficient structural support can easily lead to displacement, compression, or even damage of the internal items. Simultaneously, the end caps of the containers exhibit poor resistance to pressure and impact, failing to provide reliable protection against significant external impacts and easily deforming or breaking. These shortcomings result in poor overall structural stability and insufficient durability of existing logistics containers in complex transportation environments, making it difficult to meet the stringent requirements for transport containers carrying high-precision, high-value goods, thus hindering their application in high-end logistics scenarios. Utility Model Content

[0003] In view of this, this utility model discloses a logistics container made of aluminum alloy, which gives it structural stability. The specific solution is as follows:

The wall thickness of the axial cutting area is less than the original wall thickness of the main body of the box. The main body of the box has an uncut original wall thickness area behind the axial cutting area. The original wall thickness area of ​​the main body of the box and the axial cutting area form a stepped surface due to the height difference.

[0007] The end cap includes a cover plate and a protrusion. The protrusion has an annular structure and is disposed on the cover plate. The protrusion is embedded in the main body of the box and its outer side wall fits against the axial cutting area of ​​the main body of the box. The front end of the protrusion abuts against the stepped surface.

[0008] As a supplement to the technical solution of this utility model, the main body of the box has a square cross-section, and the four corners of the interior of the main body of the box are respectively provided with limiting connection parts for the main body of the box. The limiting connection parts are protrusions provided on the inner sidewall of the main body of the box. The limiting connection parts are located in the original wall thickness area of ​​the main body of the box, and their ends are on the same plane as the stepped surface of the main body of the box. The ends of the limiting connection parts are provided with threaded holes.

[0009] The end cap has threaded holes at the corresponding positions of the protrusion and the limiting connection part of the cover plate and the main body of the box. The bolt passes through the cover plate and the threaded hole on the protrusion of the end cap and is finally screwed into the threaded hole of the limiting connection part on the main body of the box, thus connecting the end cap to the main body of the box.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0032] like Figures 1 to 11 As shown, a logistics container is made entirely of aluminum alloy and includes a box body 1 and an end cap 2. The box body 1 is a hollow structure and has a storage space for storing and accommodating goods. The end cap 2 is located at the end of the box body 1.

[0033] The inner side of the bottom wall of the main body 1 is provided with supporting ribs to support the goods and improve the structural strength of the main body 1, preventing deformation of the main body 1 due to excessive weight of goods. An axially cut area 4 is provided on the inner side wall of the main body 1, the wall thickness of which is less than the original wall thickness of the main body 1. Behind the axially cut area 4, the main body 1 has an uncut area of ​​the original wall thickness, and the inner side wall of the original wall thickness area of ​​the main body 1 and the axially cut area 4 form a stepped surface 5 due to the height difference.

[0034] The end cap 2 includes a cover plate 6 and a protrusion 7. The protrusion 7 has a ring structure and is disposed on the cover plate 6. The protrusion 7 is embedded in the main body 1 of the container, and its outer side wall is in contact with the axial cutting area 4 of the main body 1 of the container. The front end of the protrusion 7 abuts against the stepped surface 5. The cover plate 6 is fixedly connected to the main body 1 of the container. The protrusion 7 enhances the structural strength of the cover plate 6 and improves the pressure resistance and impact resistance of the end cap 2. Meanwhile, the logistics container is made of aluminum alloy, which has excellent corrosion resistance and will not rust. Its weight is also much lower than that of traditional steel logistics containers.

[0035] As a supplement to the technical solution of this utility model, the main body 1 of the box has a square cross-section. At each of the four corners of the main body 1, a limiting connection portion 8 is integrally formed with the main body 1. The limiting connection portion 8 is a protrusion on the inner wall of the main body 1, integrally formed with the main body 1 by aluminum alloy extrusion. The limiting connection portion 8 is located in the original wall thickness area of ​​the main body 1, and its end is on the same plane as the stepped surface 5 of the main body 1. The end of the limiting connection portion 8 is provided with a threaded hole.

[0036] The end cap 2 has threaded holes at positions corresponding to the limiting connection part 8 of the main body 1, on the protrusion 7 and cover plate 6. When assembling the end cap 2 with the main body 1, the protrusion 7 of the end cap 2 is first inserted into the main body 1. Then, bolts are passed through the threaded holes on the cover plate 6 and protrusion 7 of the end cap 2, and finally screwed into the threaded hole of the limiting connection part 8 on the main body 1, thus connecting the end cap 2 to the main body 1. This design replaces the traditional steel logistics container method of welding the end cap 2 to the main body 1, achieving a detachable connection that facilitates disassembly, replacement, and recycling.

[0037] As a preferred technical solution of this utility model, such as Figure 7 As shown, the box body is a cross-sectional structural schematic diagram. The stepped surface 5 of the box body 1 is provided with a first sealing gasket mounting groove 9, and a sealing gasket is provided in the first sealing gasket mounting groove 9. By setting the sealing gasket, the sealing performance between the box body 1 and the end cover 2 is improved, ensuring the stability of the internal environment for material flow and ventilation.

[0038] As a supplement to the above technical solution, the outer edge of the cover plate 6 of the end cap 2 is bent towards the main body 1 of the housing, so that the outer edge of the cover plate 6 and the protrusion 7 form a second sealing gasket mounting groove 10. The first sealing gasket mounting groove 9 and the second sealing gasket mounting groove 10 cooperate to install the sealing gasket. The end cap 2 and the main body 1 are provided with sealing gasket mounting grooves to form a double-height sealing connection structure, which effectively protects the internal environment and enhances the reliability and durability of the seal.

[0039] As a preferred embodiment of this invention, the end cap 2 further includes an end cap reinforcing grid 11. The end cap reinforcing grid 11 is a grid-like structure composed of interlaced horizontal and vertical beams, integrally formed by extrusion. The end cap reinforcing grid 11 is disposed inside the protrusion 7 of the end cap 2, and is connected to the cover plate 6 and the protrusion 7 by welding. The addition of the end cap reinforcing grid 11 further enhances the compressive and impact resistance of the end cap 2.

[0040] As a preferred embodiment of this invention, the outer wall of the main body 1 of the enclosure is provided with heat dissipation teeth 12. The heat dissipation teeth 12 are grooves formed on the outer wall of the main body 1, and their length direction is the same as that of the main body 1. The heat dissipation teeth 12 are evenly arrayed along the circumference of the main body 1. Heat dissipation teeth 12 structures are provided on the upper surface, lower surface, left side, and right side surface of the main body 1. The arrangement of the heat dissipation teeth 12 increases the heat dissipation area of ​​the main body 1, while also providing an anti-slip effect.

[0041] As a preferred embodiment of this utility model, the main body of the box includes an upper box 13 and a lower box 14. Both the upper box 13 and the lower box 14 have U-shaped cross-sections, with their U-shaped openings facing each other. The upper box 13 and the lower box 14 are fixed together by friction stir welding. Both the upper box 13 and the lower box 14 are integrally formed by aluminum alloy extrusion. Both the upper box 13 and the lower box 14 are provided with an axial cutting area 4, a stepped surface 5, and a limiting connection part 8.

[0042] As a supplement to the above technical solution, the inner sidewall of the upper part of the lower box 14 is provided with an axially extending first stepped cutting part 15, the cutting depth of the first stepped cutting part 15 is less than the thickness of the sidewall.

[0043] The outer side wall of the lower part of the upper box 13 is provided with an axially extending second stepped cutting part 16, the cutting depth of the second stepped cutting part 16 is less than the thickness of the side wall.

[0044] The contours of the first stepped cutting part 15 and the second stepped cutting part 16 match each other, so that when the upper box 13 and the lower box 14 are connected, a stepped overlapping structure is formed; the overlapping structure is fixedly connected by friction stir welding.

[0045] The aluminum alloy logistics container disclosed in this application is a logistics transfer product designed specifically for high-performance heat dissipation requirements. It is made of 6-series aluminum alloy material, combining excellent thermal conductivity with lightweight advantages.
