Description

Technical Field

[0001] This utility model relates to the field of mechanical structural components, and in particular to a structure for adjusting and heightening the uprights of a packaging cabinet. Background Technology

[0002] In the field of mechanical structure assembly, uprights, as core basic support components, are widely used in packaging cabinets, warehouse racks, industrial equipment frames, and other scenarios. Their height specifications directly affect the adaptability and stability of the overall structure. In practical applications, different equipment models (such as packaging cabinets of different capacities or machine tools of different heights) or different working conditions of the same equipment (such as packaging cabinets adapting to materials of different heights or racks adjusting shelf heights) all require flexible adjustment of the upright height to meet the needs. However, traditional uprights are mostly integrated single-length designs, lacking adjustable structures. If the height does not match, it is impossible to adapt them using existing structures, nor is it easy to disassemble or splice them for adjustment; they must be custom-made. The customization process is not only costly and time-consuming, delaying the assembly schedule, but the customized uprights only adapt to specific needs and cannot be reused when the original height needs to be restored or adjusted again, resulting in resource waste. Some temporary non-standard methods, such as welding to lengthen or cutting to shorten, can easily damage the structural strength of the uprights, posing safety hazards. Overall, it is difficult to meet the diverse and adjustable actual needs of mechanical assembly. Utility Model Content

[0003] To address the technical problems existing in the background art, this utility model proposes a structure for adjusting and heightening the length of the uprights of a packaging cabinet.

[0004] This utility model proposes a structure for adjusting and heightening the uprights of a packaging cabinet, comprising a first upright section, with a middle layer plate fixedly connected to the bottom of the first upright section, and a second upright section disposed below the middle layer plate. Bolts are inserted inside the second upright section, and the bolts are threadedly connected to the middle layer plate to fix the second upright section.

[0005] Furthermore, a limiting member is fixedly connected to the top of the section column. The size of the limiting member is smaller than the size of the section column, so as to be inserted into the equipment for constraint.

[0006] Furthermore, the middle layer plate has symmetrically formed threaded holes inside, which are connected to the threaded ends of bolts.

[0007] Furthermore, a countersunk hole is provided on the lower surface of the second-section column, and the end of the countersunk hole extends to the upper surface of the second-section column and corresponds to the threaded hole.

[0008] Furthermore, a groove is provided on the lower surface of the middle layer plate, and a protrusion is fixedly connected to the upper surface of the second-section column, the protrusion being engaged inside the groove.

[0009] Furthermore, both the groove and the protrusion are designed as an "I" shape and are sized to be compatible for positioning during the assembly of the second-section column and to improve the stability of the assembly after assembly.

[0010] Furthermore, the middle layer plate is made of 7-series aluminum plate to improve the connection strength.

[0011] The beneficial effects of this utility model are as follows: By combining a single-section column, a middle layer plate, and a second-section column, along with bolt fastening, "I"-shaped concave-convex positioning, and a middle layer plate made of 7-series aluminum plate, the height of the second-section column can be adjusted and increased by flexibly replacing columns of different lengths to meet the height adaptation requirements of different equipment models or working conditions. This avoids the high cost and long cycle of traditional single columns that need to be customized. Furthermore, the assembly stability is ensured by multiple positioning and high-strength materials. At the same time, the bolt countersunk hole design ensures a flat appearance. Overall, this design effectively solves the pain points of traditional columns that are not height-adjustable and have poor adaptability, taking into account practicality, stability, and economy.

[0014] Reference Figure 1-4 This utility model proposes a packaging cabinet column length adjustment and heightening accessory structure, including a first-section column 1, a middle shelf 2, a second-section column 3, and bolts 4. Through the cooperation of multiple components, the column length can be adjusted and heightened, while ensuring the structural stability after connection. The first-section column 1 is the basic middle part of the column, and its bottom end is fixedly connected to the middle shelf 2. The middle shelf 2 serves as a key connecting transition limiter between the first-section column 1 and the second-section column 3, providing a supporting foundation for subsequent heightening assembly. The second-section column 3 is located below the middle layer plate 2 and is the core extension and limiting component for increasing the height of the column. To achieve a stable connection between the two, bolts 4 are inserted inside the second-section column 3, and the threaded end of the bolts 4 is threadedly connected to the middle layer plate 2. During assembly, first align the second-section column 3 with the installation position below the middle layer plate 2, then insert the bolts 4 from one side of the second-section column 3 and screw them into the corresponding connection position of the middle layer plate 2. Through the tightening action of the bolts 4, the second-section column 3 can be stably fixed below the middle layer plate 2, completing the heightening assembly of the column. If the length needs to be adjusted, a second-section column 3 of different length specifications can be replaced, and the above assembly steps can be repeated. The lower surface of the middle layer plate 2 is provided with a groove 22. Correspondingly, the upper surface of the second section column 3 is fixedly connected with a protrusion 32. Both the groove 22 and the protrusion 32 are set as "I" shaped structures. The two are matched in size. When assembling the second section column 3, the protrusion 32 is first aligned and engaged in the groove 22. Through the interlocking positioning of the "I" shaped structure, the relative installation position of the second section column 3 and the middle layer plate 2 can be quickly determined, avoiding misalignment during assembly. At the same time, the engaged "I" shaped structure can limit the relative displacement of the two in the horizontal direction, greatly improving the structural stability after assembly and preventing the column from shaking during use. The middle plate 2 has symmetrically opened threaded holes 21 inside. The threaded holes 21 match the threaded end of the bolt 4, providing a threaded mating basis for the connection of the bolt 4. The lower surface of the second section column 3 has a countersunk hole 31. The end of the countersunk hole 31 extends to the upper surface of the second section column 3, and the position of the countersunk hole 31 corresponds to the threaded hole 21 on the middle plate 2. When the bolt 4 is inserted, the bolt 4 enters from the opening end of the countersunk hole 31, passes through the second section column 3 and the countersunk hole 31 in sequence, and finally connects with the threaded hole 21. The design of the countersunk hole 31 allows the head of the bolt 4 to be embedded in it, avoiding the bolt head from protruding from the surface of the second section column 3, ensuring the flatness of the column appearance, and preventing the bolt head from being loosened by external impact. A limiting component 11 is fixedly connected to the top of the first section column 1, and the size of the limiting component 11 is smaller than the size of the first section column 1. When the entire column structure is installed on the packaging cabinet equipment, the smaller limiting component 11 can be inserted into the corresponding mounting slot or constraint structure inside the equipment. Through the limiting effect of the internal structure of the equipment on the limiting component 11, the top of the first section column 1 is fixedly constrained, which further enhances the installation stability of the entire column in the packaging cabinet equipment and avoids the top of the column from shifting or shaking. In addition, the middle layer plate 2 is made of 7-series aluminum plate. 7-series aluminum plate has high strength, good mechanical properties and corrosion resistance. Compared with ordinary metal plates, it can greatly improve the load-bearing capacity and connection strength of the middle layer plate 2, ensuring that it is not easily deformed or damaged when bearing a section of column 1 and external loads, thus extending the service life of the entire column structure.
