[0020] The following detailed description illustrates the specific implementation method: like Figures 1 to 5 As shown, this utility model includes a support frame, which comprises a top frame portion and a bottom frame portion fixed together. The top frame portion consists of a top longitudinal tube 8, a vertical steel tube 10, and a top horizontal tube 9. The top longitudinal tube 8 and the top horizontal tube 9 are both welded to the vertical steel tube 10. The bottom frame portion consists of the vertical steel tube 10, a bottom longitudinal tube 14, and a bottom horizontal tube 16. The bottom longitudinal tube 14 and the bottom horizontal tube 16 are both welded to the vertical steel tube 10. The top frame portion and the bottom frame portion share the vertical steel tube 10. Two fixed baffles 18 and two first steel wheels 19 are provided on the inner side of one end of the top longitudinal tube 8. The first steel wheels 19 abut against the fixed baffles 18. The two first steel wheels 19 are respectively fixed to the two ends of a corresponding first circular tube 20. The outer side of 20 is fixed to a first supporting steel pipe 21. The first supporting steel pipe 21 is fixed to one end of a plurality of inclined supporting pipes 23. The other end of each inclined supporting pipe 23 is fixed to a middle supporting short round pipe 2. The inner side of the top longitudinal pipe 8 is also provided with two second steel wheels 24. The second steel wheels 24 are respectively fixed to the two ends of a corresponding second round pipe 4. The outer side of the second round pipe 4 is fixed to a second supporting steel pipe 6. A plurality of front supporting pipes 1 are fixed on the second supporting steel pipe 6. A plurality of material round pipes 3 are connected to the front supporting pipes 1. The front supporting pipes 1 and the middle supporting short round pipes 2 are arranged alternately. A solid seamless long round pipe 5 passes through the front supporting pipes 1 and the middle supporting short round pipes 2. A positioning hole 81 is provided on the top longitudinal pipe 8. The movable baffle 7 is partially inserted into the positioning hole 81.

[0021] The bottom end of the upright steel pipe 10 is fixed with a stacked steel pipe 12. The inner diameter of the stacked steel pipe 12 is equal to the outer diameter of the upright steel pipe 10. The inner diameter of the stacked steel pipe 12 and the outer diameter of the upright steel pipe 10 are perfectly matched to form a tight nested structure. The nested structure avoids the "loose gap" when the two are connected, reducing the shaking or displacement of the upright steel pipe 10 when subjected to lateral forces (such as material offset or equipment push). In addition, it facilitates the multi-layer stacking of multiple foldable material racks, reducing the waste of space. The bottom horizontal pipe 16 is equipped with multiple casters 13. The multiple casters 13 can move the foldable material rack, and ensure that the movement is stable, reducing the risk of material bumping and spilling.

[0022] In addition, one side of the upright steel pipe 10 is provided with a hook 11. There are four hooks 11, and each hook 11 corresponds to one upright steel pipe 10. After entering the folding posture, the stacked steel pipe 12 can be aligned with another material rack upright steel pipe 10 for multi-layer stacking by connecting the hook 11 with a gantry crane or a forklift, which is convenient to use.

[0023] like Figure 5As shown, the top longitudinal tube 8 has a C-shaped cross-section and a groove 82 is provided on the inner side of the top longitudinal tube 8 to facilitate the movement of the first steel wheel 19 and the second steel wheel 24 in the groove 82, while preventing the first steel wheel 19 and the second steel wheel 24 from detaching from the top longitudinal tube 8.

[0024] The movable baffle 7 is connected to one end of a chain 15, and the other end of the chain 15 is fixed to the top longitudinal tube 8. This can prevent the movable baffle 7 from being lost and also limit the movement of the movable baffle 7.

[0025] Furthermore, a support plate 22 is fixed on each side of the bottom end of the first support steel pipe 21. When it enters the folding posture, the front support pipe 1 falls on the support plate 22, thereby supporting the front support pipe 1 and increasing stability.

[0026] Specifically, at least one vertical support pipe 17 is welded between the top horizontal pipe 24 and the bottom horizontal pipe 16, and at least one horizontal support pipe 25 is welded between the two bottom horizontal pipes 16. The vertical support pipe 17 increases the structural strength between the top horizontal pipe 24 and the bottom horizontal pipe 16, and the horizontal support pipe 25 increases the structural strength between the two bottom horizontal pipes 16 to prevent deformation under pressure.

[0027] In a specific application scenario, a PVC pipe is fitted onto the material tube 3. The top longitudinal tube 8 and the top transverse tube 9 are both fixed to a placement plate 26. The length of the placement plate 26 extends from the positioning hole 81 to the top transverse tube 9. The PVC pipe protects the material tube 3 from external environmental corrosion and friction, such as preventing corrosion from acids and alkalis, reducing wear caused by friction, and extending the service life of the material tube 3. The placement plate 26 facilitates the placement, retrieval, and operation of items by operators.

[0028] The working principle of this utility model is as follows: After entering the folding posture (i.e., when no materials need to be placed), the movable baffle 7 is fully pulled out from the positioning hole 81. The movable baffle 7 will not block the second steel wheel 24, thus releasing the restriction on the second steel wheel 24. The second steel wheel 24 moves towards the side of the placement plate 26 (i.e., away from the first circular tube 20). The middle support short circular tube 2 rotates around the solid seamless long circular tube 5, thereby driving the front support tube 1 and the inclined support tube 23 to move downward. The inclined support tube 23 slowly flattens, finally driving the material circular tube 3 to rotate, so that the material circular tube 3 is completely perpendicular to the ground, which facilitates the multi-layer stacking of multiple material racks (e.g., ...). Figure 6As shown in the diagram, it is easy to use. After entering the raised position (i.e., when materials need to be placed), push the second support steel pipe 6 towards the side of the first round pipe 20, causing the second steel wheel 24 to move towards the side of the first round pipe 20 (i.e., close to the first round pipe 20). The middle support short round pipe 2 rotates around the solid seamless long round pipe 5, thereby driving the front support pipe 1 and the inclined support pipe 23 to move upward. The inclined support pipe 23 slowly rises, eventually driving the material round pipe 3 to rotate. The movable baffle 7 is partially inserted into the positioning hole 81, blocking the second steel wheel 24, thus restricting the second steel wheel 24 and keeping the material round pipe 3 in an upward inclined state with the ground. This facilitates the placement of different materials such as gears, bearings, retaining rings, sealing gaskets, and O-rings on the material round pipe 3. In addition, there are multiple material round pipes 3, which can meet the needs of different materials with different specifications and sizes. This allows for the use of material racks of the same specification, saving costs and facilitating the subsequent multi-layer stacking of multiple material racks. This utility model can also replace different material round pipes 3, making it widely applicable and easy to use.

[0029] In summary, this utility model can replace traditional material racks for storing various materials such as gears, bearings, retaining rings, sealing gaskets, and O-rings, saving space and improving site utilization. Through this folding method, multiple material racks can be stored by quickly folding and stacking, reducing the waste of site space.
