Abstract
Description
Technical Field
[0001] This utility model relates to an aluminum rod that prevents it from rolling. Background Technology
[0002] In existing technologies, aluminum rod structures are mainly cylindrical, with some designed as annular (tubular). Such structures require external support frames, primarily because aluminum rods are prone to rolling and are difficult to pack and secure. Therefore, this invention was specifically designed to address this issue. Utility Model Content
[0003] To address the aforementioned problems in the prior art, this invention provides an aluminum rod that prevents rolling and its supporting frame, which can improve upon the above deficiencies.
[0004] This utility model relates to an aluminum rod that prevents rolling, comprising an aluminum rod body with large ends at both ends. The length and width dimensions of the cross-section of the middle region of the aluminum rod body are smaller than the length and width dimensions of the cross-section of the large ends. The fifth plane (bottom surface) of the large ends is a horizontal support surface, forming a stable fulcrum when in contact with the ground to prevent the aluminum rod from rolling. In the direction perpendicular to the length of the aluminum rod, the cross-section of the middle of the aluminum rod body is irregular. The side of the aluminum rod body sequentially includes a first elliptical surface, a first horizontal surface, a second elliptical surface, a first vertical surface, a third elliptical surface, a second horizontal surface, a fourth elliptical surface, and a second vertical surface. The first horizontal surface and the second horizontal surface are parallel to each other, and the first vertical surface and the second vertical surface are parallel to each other.
[0005] Furthermore, in the direction perpendicular to the length of the aluminum rod, the first elliptical surface, the second elliptical surface, the third elliptical surface and the fourth elliptical surface are arc segments on the same ellipse, and the ratio of their major semi-axis to minor semi-axis is 1.153 to 1.224.
[0006] Furthermore, the width ratio of the first horizontal plane to the width of the first vertical plane is 2.09 to 2.12.
[0007] Furthermore, the large end portion includes a first plane, a second plane, a third plane, a fourth plane, a fifth plane, and a sixth plane. The second plane is parallel to the fifth plane. The first plane is inclined relative to the third plane and located on both sides of the second plane. The fourth plane is parallel to each other and located perpendicularly on both sides of the fifth plane. The third plane is adjacent to the fourth plane. The first plane is adjacent to the sixth plane. The width of the second plane is smaller than the width of the fifth plane.
[0008] Furthermore, the first plane is parallel to the first horizontal plane.
[0009] This invention features a clever improvement: by designing the larger end to have a flat surface that contacts the horizontal plane, it prevents the aluminum rods from rolling and facilitates their movement. For example, when the aluminum rods are stacked, the sixth plane contacts the ground to prevent rolling; during movement, the rope can pass through the middle of the aluminum rod body, with the rope loop close to the inside of the larger end, which acts as an anti-detachment mechanism.
[0010] In addition, in the direction perpendicular to the length of the aluminum rod, with the lowest point of the sixth plane as the reference, the height difference from the highest point of the second horizontal plane is 10 to 15 cm. This size design helps to ensure the stability of the aluminum rods when stacked, allowing the larger end to make better contact with the ground and avoid rolling.
[0011] The aluminum rod body is made of 6061 aluminum alloy, which belongs to the 6xxx series and possesses a range of excellent physical and chemical properties. Physically, it exhibits high strength, with a yield strength of up to 240 MPa and a tensile strength of 290 MPa. This makes the aluminum rod resistant to deformation under significant external forces, meeting the requirements of various engineering structures. Simultaneously, this aluminum alloy also possesses good hardness, with a Brinell hardness of 95 HB, effectively enhancing the wear resistance of the aluminum rod and extending its service life. Particularly in the structural design of the large end, the high strength and good hardness of the aluminum alloy help ensure the structural stability of the large end, thereby better achieving the function of preventing rolling.

Detailed Implementation
[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.
[0017] like Figure 1-3As shown, this utility model relates to an aluminum rod that prevents rolling, comprising an aluminum rod body with large-end ends 10 at both ends. The length and width dimensions of the cross-section of the middle region of the aluminum rod body are smaller than the length and width dimensions of the cross-section of the large-end ends, and the large-end ends have a plane in contact with a horizontal plane. In the direction perpendicular to the length of the aluminum rod, the cross-section of the middle of the aluminum rod body is irregularly shaped. (Viewed from one end of the aluminum rod) The side of the aluminum rod body sequentially includes a first elliptical surface 2, a first horizontal plane 3, a second elliptical surface 4, a first vertical plane 5, a third elliptical surface 6, a second horizontal plane 7, a fourth elliptical surface 8, and a second vertical plane 9. The first horizontal plane and the second horizontal plane are parallel to each other, and the first vertical plane and the second vertical plane are parallel to each other. Each surface and plane is smoothly transitioned with a transition radius r = 2-3 mm to ensure no stress concentration, thus ensuring the integrity and stability of the structure.
[0018] As a technical improvement, in the direction perpendicular to the length of the aluminum rod, the first elliptical surface 2, the second elliptical surface 4, the third elliptical surface 6 and the fourth elliptical surface 8 are arc segments on the same ellipse, and the ratio of their major semi-axis to minor semi-axis is 1.153 to 1.224.
[0019] The width ratio of the first horizontal plane to the first vertical plane is 2.09 to 2.12. Here, the width direction is defined as the transverse dimension perpendicular to the length of the aluminum rod and within the cross-section, calculated proportionally based on the transverse dimension of the first vertical plane. For example, assuming the width of the first vertical plane is 5cm, then the width of the first horizontal plane is 10.45cm to 10.6cm.
[0020] As a technical improvement, the large end portion includes a first plane 101, a second plane 102, a third plane 103, a fourth plane 104, a fifth plane 105, and a sixth plane 106. The second plane is parallel to the fifth plane, the first plane is inclined relative to the third plane and located on both sides of the second plane, the fourth plane is parallel to each other and perpendicular to the fifth plane on both sides, the third plane is adjacent to the fourth plane, the first plane is adjacent to the sixth plane, and the width of the second plane is smaller than the width of the fifth plane.
[0021] As a technical improvement, the first plane is parallel to the first horizontal plane. When the aluminum bars are stacked, the sixth plane contacts the ground, preventing rolling. The presence of the larger end also facilitates the movement of the aluminum bars. A rope can pass through the middle of the aluminum bar body, with the rope loop close to the inside of the larger end, which acts as an anti-slip mechanism. In terms of design, the height difference between the lowest point of the sixth plane and the highest point of the second horizontal plane along the direction perpendicular to the length of the aluminum bar is 10-15 cm. This dimensional design helps ensure the stability of the aluminum bars during stacking, allowing the larger end to better contact the ground and preventing rolling. The aluminum bar body is made of 6061 aluminum alloy. This aluminum alloy belongs to the 6xxx series and possesses a series of excellent physical and chemical properties. Physically, it has high strength, with a yield strength of up to 240 MPa and a tensile strength of 290 MPa. This makes the aluminum bars less prone to deformation under large external forces, meeting the requirements of various engineering structures. Taking a single aluminum rod bearing a load of 1000N as an example, the compressive stress σ = F / S = 1000N / (0.05m × 0.1m) = 200kPa at the bottom surface (fifth plane) of the large end, is much less than the yield strength (240MPa) of 6061 aluminum alloy, ensuring no deformation during long-term use. At the same time, this aluminum alloy also possesses good hardness, with a Brinell hardness of 95HB, effectively enhancing the wear resistance of the aluminum rod and extending its service life.
