[0002] Stackable racks are designed for storing and organizing items, characterized by their ability to be stacked to increase storage space. They are primarily used in warehousing, logistics, and home organization, and fall under the category of storage and organization devices. Typically made of materials such as metal, plastic, and wood, their stackable design effectively utilizes vertical space, making them particularly suitable for environments with limited space. Individual modules are lightweight and easy to disassemble and reassemble, making them widely used in warehousing, home organization, and retail. Their flexibility and space-optimizing properties have made them an indispensable tool in modern life.

[0003] In valve production, due to the high mass of the product, the structural strength of the rack is paramount.

[0031] An upper support plate 300 is provided on the upper surface of the upper structure frame 200;

[0032] Four support members 400 are respectively arranged at the four corners of the stackable rack. The support members 400 are angle iron shaped. The support members 400 extend upward from the middle of the thickness direction of the lower structural frame 100 and exceed the lower structural frame 100. The inner wall of the support member 400 is connected to the outer wall of the upper structural frame 200 and the lower structural frame 100.

[0033] In the prior art, it is difficult for the storage racks related to the valve field to meet the requirements of convenient processing, convenient assembly and high structural strength.

[0034] The stackable rack provided by the present invention includes a lower structural frame 100 , an upper structural frame 200 , an upper support plate 300 and a support member 400 .

[0035] The lower structural frame 100 includes four lower tubes 110 connected end to end. The connection between the lower tubes 110 is not limited to direct connection (such as mutual welding), and can also be indirectly connected through other structures (such as through angle brackets).

[0036] The upper structural frame 200 is positioned above the lower structural frame 100. The space between the upper structural frame 200 and the lower structural frame 100 forms a ventilation foundation and storage space. The upper structural frame 200 comprises four upper tubes 210 connected end-to-end. The connection between the upper tubes 210 is not limited to direct connection (e.g., welding); indirect connection (e.g., through angle brackets) can also be achieved. The upper tubes 210 and the lower tubes 110 share the same structural design, namely, the same parameters such as length and cross-section.

[0037] The upper support plate 300 is disposed on the upper surface of the upper structural frame 200 . The upper support plate 300 forms a base on which the valve is placed.

[0038] Four support members 400 are positioned at the four corners of the stackable rack, forming the support base. The support members 400 are angle iron. They extend upward from the middle of the thickness of the lower structural frame 100 and extend beyond it. The inner walls of the support members 400 are connected to the outer walls of the upper and lower structural frames 200 and 100. The connection between the support members 400 and the upper and lower structural frames 200 and 100 can be welded or bolted.

[0039] During operation, the lower structural frame 100 enhances the structural strength of the four support members 400, increasing the support and ventilation space of the stackable rack. The valves are placed on the upper support plate 300, providing ample storage space and ventilation. During stacking, the lower stackable rack is stably supported. The lower structural frame 100 of the lower stackable rack is connected to the four support members 400 of the lower stackable rack via the four support members 400 connected thereto.

[0040] In summary, the upper structural frame 200 is supported on the lower structural frame 100 by four support members 400 to form a ventilation foundation and storage space. The four support members 400 are respectively arranged at the four corners to constitute a support foundation. The support members 400 start from the middle of the thickness direction of the lower structural frame 100 and extend upward and exceed the lower structural frame 100; in the stacking process, the upper lower structural frame 100 is hung on the four support members 400 below through the four support members 400 connected thereto; the structure is simple and easy to use, meeting the requirements of valve storage.

[0042] In this embodiment, the support member 400 connects the lower structure frame 100 and the upper structure frame 200 , and also connects the adjacent lower tubes 110 and the adjacent upper tubes 210 , thereby greatly reducing the difficulty of installation and maintenance.

[0043] In one embodiment, the adjacent upper tubes 210 are connected through the support member 400, and the connection method between the support member 400 and the upper tube 210 is welding; the adjacent lower tubes 110 are connected through the support member 400, and the connection method between the support member 400 and the lower tube 110 is welding.

[0044] In this embodiment, the support member 400 is used to connect the lower structure frame 100 and the upper structure frame 200 , and the adjacent lower tubes 110 and the adjacent upper tubes 210 are also connected. The connection by welding has the advantage of high structural strength.

[0045] In one embodiment, adjacent upper tubes 210 are welded together, and adjacent lower tubes 110 are welded together.

[0046] In this embodiment, adjacent upper tubes 210 are welded together to achieve structural complementation, further enhancing the structural stability of the entire upper structural frame 200. Adjacent lower tubes 110 are welded together to achieve structural complementation, further enhancing the structural stability of the entire lower structural frame 100. In particular, when the support members 400 are secured by welding, adding several weld points is convenient.

[0047] In one embodiment, a lower connecting rib is provided in the middle of the lower structure frame 100 .

[0048] In this embodiment, the lower connecting ribs improve the structural strength of the lower structural frame 100 and reduce the possibility of deformation. The lower connecting ribs can be connected to the lower tube 110 by welding or the like.
