[0007] As a preferred solution, the main frame is further provided with a number of second circular through-holes arranged in a rectangular pattern, which can effectively utilize the space of the main frame.

[0008] As a preferred solution, the second circular through-holes are arranged at the exact center of four adjacent first circular through-holes, enhancing the structural strength and stability of the overall frame.

[0009] As a preferred solution, the diameter of the second circular through-holes is larger than that of the first circular through-holes, in order to provide additional fixing points or support points to meet the requirements of crankshafts or other related components of different specifications and models.

[0021] The technical solution of the present utility model will be further specifically described below through embodiments in conjunction with the accompanying drawings.

[0022] Embodiment:

[0023] A compressor is a mechanical device used to increase gas pressure and is widely used in fields such as refrigeration, air conditioning, and gas transportation. The crankshaft is an important component inside the compressor, and its function is to convert the rotational motion of the power machine into a reciprocating motion, thereby driving the piston of the compressor to perform compression work. The turnover box for placing the compressor crankshaft is a device specifically used for storing and transporting the compressor crankshaft, and its design must meet the storage safety and transportation stability of the crankshaft. The crankshaft is one of the core components of the compressor, and its function is to convert the rotational motion of the electric motor or internal combustion engine into the reciprocating motion of the piston, thereby realizing the compression of gas. Therefore, during transportation and storage, it is necessary to ensure that the crankshaft is not damaged and maintain its machining accuracy and surface finish to ensure the good performance of the compressor.

[0024] The present application provides a turnover box for placing a compressor crankshaft 6, which includes a main box 1 in a rectangular shape. The top view of the turnover box is rectangular, and this design is beneficial for saving space and facilitating stacking. The rectangular frame structure provides greater structural strength, capable of bearing the weight of the crankshaft 6 itself and the external forces that may be received during transportation. At the same time, the rectangular frame is convenient for arranging and fixing in a warehouse or a transportation vehicle, thereby improving the utilization rate of space. The main box 1 is provided with a number of first circular through holes 2 arranged in a rectangular pattern, and corresponding-sized crankshafts 6 are provided in the first circular through holes 2. The design of these through holes is to accommodate and fix specific parts of the crankshaft 6. The shape and size of the through holes are precisely designed to ensure that the crankshaft 6 can be stably placed in the frame, preventing displacement or collision during transportation and causing damage to the crankshaft 6. Gaskets 3 are provided around the circular through holes. When the crankshaft 6 is placed in the first circular through hole 2, the surrounding gaskets 3 can play a role in supporting and fixing. The gaskets 3 can not only improve the stability of the crankshaft 6 but also buffer external vibrations and impacts to a certain extent, protecting the surface of the crankshaft 6 from scratches. To further improve the fixing effect of the crankshaft 6, a pedestal 21 extends from the first circular through hole 2 to the side away from the gasket 3. The design of the pedestal 21 is to increase the depth of the through hole, enabling the crankshaft 6 to be more deeply embedded therein, thereby improving its fixing effect. In the present application, the height and shape of the pedestal 21 are precisely calculated to ensure that while providing sufficient supporting force, it will not cause damage to the crankshaft 6. The central section of the gasket 3 bends in the direction away from the corresponding first circular through hole 2. This design is to increase the overall structural strength and stability of the turnover box. The bent gasket 3 can not only improve the load-bearing capacity of the turnover box but also effectively disperse the externally applied forces, reducing the stress concentration on a single part, thereby reducing the risk of damage to the turnover box. The bending design can also compensate for the thermal expansion and contraction characteristics of the material to a certain extent, reducing the influence of environmental temperature changes on the turnover box.

[0025] In terms of material selection for the present application, high-strength metal or engineering plastic materials are usually adopted. These materials have good mechanical properties and durability. Metal materials such as steel can provide extremely high strength and rigidity, being suitable for application scenarios that need to bear large weights and impacts. Engineering plastic materials such as polyethylene or nylon have good wear resistance and chemical corrosion resistance, being suitable for occasions that need to be frequently handled and used under various environmental conditions. The selection of materials also needs to consider cost factors and the complexity of the manufacturing process.

[0026] In terms of manufacturing processes, the present application can adopt die injection molding or metal welding and splicing processes. The die injection molding process is suitable for turnover boxes made of plastic materials, having the advantages of high production efficiency, low cost, and high precision. The metal welding and splicing process is suitable for turnover boxes made of metal materials, capable of ensuring the structural stability and durability. In addition, modern numerical control processing technologies can also be combined to improve the processing precision and consistency of the products.

[0027] The usage scenarios of this application include compressor manufacturing plants, repair workshops, and various transportation links. In the manufacturing plant, the turnover box is used to safely store and transport the produced crankshaft 6 to the assembly line. In the repair workshop, the turnover box is used to store and transport the crankshaft 6 that needs to be replaced or maintained. In the transportation link, the turnover box can effectively protect the crankshaft 6 from vibration and impact during transportation, ensuring its integrity and quality.

[0028] Generally speaking, the design of placing the compressor crankshaft 6 in the turnover box of this application is functionally aimed at providing a safe, efficient, and economical transportation and storage solution for the crankshaft 6. Through the carefully designed structure and reasonably selected materials, this turnover box can not only meet the high requirements of modern industry for product quality and efficiency, but also adapt to different usage environments and working conditions. It plays an important role in the compressor industry, providing a reliable guarantee for the safe transportation and storage of the crankshaft 6.

[0029] The main frame 1 is also provided with a number of second circular through holes 4 arranged in a rectangular pattern. The second circular through holes 4 are provided at the exact center of four adjacent first circular through holes 2. Such a layout design is not only for visual symmetry and aesthetics, but also has practical functional significance. Arranging the second circular through holes 4 at the center of the four first circular through holes 2 can effectively utilize the space of the main frame 1 and improve the structural strength and stability of the overall frame. Because setting through holes at the center position can balance the force distribution around, thus reducing the stress concentration phenomenon caused by uneven loads. This mechanical balance can, to a certain extent, extend the service life of the turnover box and reduce the risk of material fatigue and damage. The diameter of the second circular through holes 4 is larger than that of the first circular through holes 2., This design detail reflects its specific functional use. The larger diameter means that it can accommodate larger components or additional devices than the first circular through holes 2. This design may be to provide additional fixing points or support points to adapt to the needs of different specifications and models of the crankshaft 6 or other related components. In practical applications, the second circular through holes 4 can be used to fix additional support structures or adjustment devices to enhance the multi-functional applicability of the turnover box. This flexible design enables the turnover box to adapt to different industrial scenarios and specific usage requirements, providing a modular and scalable solution.

[0030] In terms of material selection and manufacturing process, the design including the second circular through hole 4 may require higher precision and more complex processing technology. In order to ensure the accurate size and position of the through hole, modern industry usually uses high-precision CNC machine tools for processing. This can not only ensure that the shape and size of each through hole meet the design standards, but also ensure that they are accurately arranged on the main frame 1. Through high-precision processing technology, the turnover frame can not only maintain structural integrity, but also provide stable performance and reliable safety during use.

[0031] The turnover frame provided with the second circular through hole 4 may involve more diverse usage scenarios in practical applications. For example, on a large compressor production line, different models of crankshafts 6 may need to be transported and stored using the same turnover frame. The versatility of the second circular through hole 4 can adapt to the needs of these different models, thereby reducing the company's investment in tools and equipment. In addition, during transportation, the second circular through hole 4 can be used to quickly install and remove additional fixtures or protective measures, further improving safety and efficiency during transportation.

[0032] Several strip columns 5 are arranged on the four sides of the main frame 1. The strip columns 5 on the short sides of the main frame 1 are arranged symmetrically. The strip columns 5 on the long sides of the main frame 1 are unequal on both sides. Not only does it provide additional structural support, it may also play a role in protection and fixation during the use of the turnover frame. The strip columns 5 are evenly distributed on the four sides of the main frame 1. This design is obviously to enhance the overall rigidity and stability of the frame. By arranging the strip columns 5 at the edge of the structure, the turnover frame can better resist collisions and pressure from the outside, thereby effectively protecting the crankshaft 6 and other components inside.

[0033] The strip columns 5 are symmetrically arranged along the short sides of the main frame 1. This symmetrical design is designed to achieve balanced and evenly distributed force management. During transportation and handling, the symmetrically arranged strip columns 5 can evenly disperse the external forces applied to the turnover frame. Therefore, no matter how the turnover frame is lifted or placed, its structure can remain stable, reducing the risk of tilting or damage due to imbalance. In addition, symmetrical design usually helps to simplify the manufacturing process, because symmetrical parts are easier to mass produce and assemble, thereby reducing production costs.

[0034] On the other hand, the strip columns 5 on the long side of the main frame 1 are unequally distributed on both sides. This asymmetric design may serve multiple functional requirements. First, it is to adapt to different load requirements. For example, one side of the long side may need to bear more weight or require additional support, and the asymmetric strip column 5 setting can provide this additional stability. Such a design can ensure that the turnover frame can still maintain balance and stability even under heavy or uneven load conditions.

[0035] This asymmetrical layout may also take into account the functional requirements of the turnover box during specific operations. For example, if frequent opening, closing, or adjustment is required on one side, the arrangement of the strip columns 5 may leave more space for the operation. By reducing the number of strip columns 5 on one side, the design can improve the flexibility and operational convenience of the turnover box without affecting the overall structural integrity.

[0036] Another possible consideration is aesthetics and design aesthetics. In industrial design, in addition to functionality, the visual effect of the product is also an important consideration. The asymmetrical design can add a dynamic visual effect to the turnover box, making it more modern and attractive in appearance. This design can not only enhance the market competitiveness of the product but also meet the needs of specific customers for personalized and innovative designs.

[0037] In addition, the strip columns 5 can also provide additional functions during handling. They can serve as handles or gripping points, facilitating the handling and adjustment of the turnover box by the operator. Especially in situations where frequent movement is required, the reasonable layout of the strip columns 5 can significantly improve operational efficiency and safety.

[0038] In terms of material selection, the strip columns 5 usually need to have high strength and wear resistance because they need to withstand various external forces and friction. Commonly used materials include high-strength alloy steel or durable engineering plastics, which can provide sufficient support and durability while maintaining a certain lightweight advantage. The lightweight design helps reduce transportation costs and improve operational convenience, which is particularly important in modern industrial applications.

[0039] From the perspective of manufacturing processes, the setting of the strip columns 5 requires precise machining and assembly to ensure that they can perform their best functions during use. Advanced manufacturing technologies such as numerical control machining and automated assembly lines can help achieve high-precision production of the strip columns 5, thereby improving the consistency and reliability of the product.

[0040] In practical applications, this design can be widely used in fields such as compressor manufacturing, maintenance, and logistics transportation. They can provide a safe and stable storage and transportation environment for key components such as the crankshaft 6, ensuring high efficiency and low risk throughout the supply chain process. The flexibility and versatility of this design enable it to adapt to changing industrial requirements and environmental conditions.

[0041] In summary, the bar columns 5 of the turnover box for placing the compressor crankshaft 6 play a key role in function realization, structural stability, and operation convenience. Through the carefully designed layout of the bar columns 5, the turnover box not only has strong structural support and load capacity, but also can provide a flexible operation experience and good visual effect. This design concept reflects how to improve the overall performance and market competitiveness of industrial products through innovation and detail optimization in industrial product design. Through such comprehensive design considerations, the turnover box for placing the compressor crankshaft 6 can better meet the high requirements of modern industry for product safety, reliability, and economy.
