Description

Technical Field

[0001] This application relates to a base frame, a storage cage, and a method for manufacturing the base frame. Background Technology

[0002] Warehouse cages, also known as storage cages or storage boxes, offer advantages such as fixed storage capacity, neat stacking, clear visibility of stored items, and ease of inventory counting, while also improving the effective utilization of storage space.

[0003] A storage cage may include a base frame and a base frame support mesh, with the mesh surrounding and providing storage space for the storage cage.

[0004] However, the inventors discovered during the process of completing this application that the surface of the base frame would have poor surface quality after being placed for a period of time. Summary of the Invention

[0005] In view of the problems existing in the background art, the purpose of this application is to provide a base frame, a warehouse cage, and a method for manufacturing the base frame, so as to solve the problem of surface corrosion that occurs on the surface of the base frame after being placed for a period of time, and to improve the product quality of the base frame and the warehouse cage.

[0007] In the technical solution of this application embodiment, there is a gap between the supporting surface of the beam and the supporting leg of its corresponding support. The supporting leg and the supporting surface of the beam are fixedly connected through an intermediate structure. This avoids the problem of electroplating solution accumulating in the surface-to-surface bonding structure and being difficult to flow out during the subsequent electroplating process due to the surface-to-surface bonding welding between the supporting surface of the beam and the supporting leg of the corresponding support. After a period of time, the electroplating solution seeps out, causing surface corrosion. The gap structure facilitates the smooth flow of the electroplating solution and avoids the problem of surface corrosion caused by the accumulation of the electroplating solution and its seepage after a period of time.

[0011] In some embodiments, the base frame is a structure with at least two layers, including an upper structure and a lower structure. The upper structure is located above the lower structure. The lower structure includes the base and the support legs. The upper structure includes beams of the upper structure supported by the support legs.

[0012] In some embodiments, the base includes at least two first crossbeams and at least one longitudinal beam, the crossbeams supporting the support legs and the longitudinal beam connecting the at least two first crossbeams.

[0013] In some embodiments, the base further includes a second crossbeam, the height of which is the same as the support height of the support foot. The upper structure includes a crossbeam and a longitudinal beam, the support foot supports the crossbeam of the upper structure, and the second crossbeam supports the longitudinal beam of the upper structure.

[0014] In some embodiments, the support feet are distributed in the corner areas of the base frame, and the support feet are also connected to hooks.

[0015] Secondly, this application provides a warehouse cage, including a wire mesh and a base frame as described in any one of the first aspects, wherein the base frame supports the wire mesh, and the wire mesh provides storage space for the warehouse cage.

[0016] Thirdly, this application provides a method for manufacturing a base frame, wherein the base frame is the base frame described in any one of the first aspects, and the manufacturing method includes...

[0040] The storage cage may include a base frame and a base frame support mesh, the mesh surrounding and providing storage space for the storage cage. The base frame includes a base, including beams; and support legs, the beams being supported by the base.

[0041] The inventors of this application discovered that when manufactured warehouse cages are stored in a warehouse, after a period of time, poor surface quality develops near the connection area between the support legs and their corresponding beams. Furthermore, even after localized repairs to the areas with poor surface quality, the problem recurs after a period of time, making it difficult for products with poor surface quality to meet delivery requirements.

[0042] To address the issue of poor surface quality in warehouse cages after a period of storage, ensuring they meet delivery requirements, the inventors, after in-depth research, discovered that the poor surface quality stems from the use of surface-to-surface welding between the beam's supporting surface and the corresponding support legs. During the electroplating process following the warehouse cage manufacturing process, a small amount of electroplating solution accumulates in this surface-to-surface welded structure and is difficult to drain after electroplating. After manufacturing is complete, storing the finished warehouse cages in a warehouse for a period causes the electroplating solution to seep out, leading to surface corrosion—the discovered problem of poor surface quality. Since surface corrosion indicates that the electrochemical corrosion caused by the electroplating solution has progressed to a certain stage, even localized repairs of the poor-quality areas will result in the reappearance of poor surface quality after a period of time.

[0043] The inventors discovered that it is necessary to ensure the smooth flow of the electroplating solution within the base frame structure, preventing accumulation due to obstructed flow in certain areas. Therefore, the inventors designed a structure with gaps between the beam's support surface and its corresponding support legs, facilitating the smooth outflow of the electroplating solution, reducing the risk of later seepage, and improving surface quality.

[0044] The base frame disclosed in this application can be used, but is not limited to, for warehouse cages, and can also be applied to other base frame structures that employ electroplating processes.

[0045] According to some embodiments of this application, refer to Figure 1 This application provides a storage cage 10, including a base frame 1 and a wire mesh 2. The base frame 1 supports the wire mesh 2, and the wire mesh 2 provides storage space S for the storage cage 10 to place items that need to be stored in the storage cage 10.

[0046] Continue to refer to Figures 2 to 4 As shown, in some embodiments, the base frame 1 includes a base 11 and support legs 12. The base 11 includes a beam 111, and the support legs 12 are supported on the beam 111. Figure 4 As shown, there is a gap G1 between the support surfaces 1111 and 1112 of beam 111 and the support legs 12 of their corresponding supports. The support legs 12 are fixedly connected to the support surfaces 1111 and 1112 of beam 111 through an intermediate structure 13.

[0047] In this context, beam 111 refers to the structural component in base 11 that bears the load, and the deformation caused by the external forces it bears is mainly bending. Support leg 12 refers to the component that supports the corresponding part to a certain height.

[0048] There is a gap G1 between the supporting surfaces 1111 and 1112 of beam 111 and their corresponding supporting legs 12. The supporting legs 12 are fixedly connected to the supporting surfaces 1111 and 1112 of beam 111 through an intermediate structure 13. This means that the supporting surfaces 1111 and 1112 of beam 111 and the connecting surfaces 1211 and 1212 of supporting legs 12 are not perfectly flush, but have a certain gap. The intermediate structure 13 is a structure existing within the gap; it does not restrict the intermediate structure 13 from being formed separately and then fixedly connected to beam 111 or supporting legs 12, or it can be integrally formed with either beam 111 or supporting legs 12 and then fixedly connected to the other. The specific structure of the fixed connection can be welding, bonding, etc., but is not limited to these methods. The specific value of the gap G1 is determined according to the different types of electroplating solutions and electroplating process parameters. It should be sufficient to allow the electroplating solution to flow out smoothly. Of course, it is understandable that the gap G1 should not be too large, as it may cause the fixed connection structure between the support leg 12 and the support surfaces 1111 and 1112 of the beam 111 to be unstable.

[0049] As mentioned above, the base frame 1 adopts a structure with a gap G1 between the support surfaces 1111 and 1112 of the beam 111 and the corresponding support feet 12. This avoids the problem of electroplating solution accumulating in the surface-to-surface bonding structure and being difficult to flow out during the subsequent electroplating process due to the surface-to-surface bonding welding between the support surfaces of the beam 111 and the corresponding support feet 12, which leads to surface corrosion after a period of time. The gap structure facilitates the smooth flow of electroplating solution and avoids the problem of surface corrosion caused by the accumulation of electroplating solution and its seepage after a period of time, thereby improving the surface quality of the base frame and the warehouse cage.

[0050] According to some embodiments of this application, optionally, please continue to refer to Figures 2 to 4The intermediate structure 13 can specifically include inwardly recessed structures 1113 and 1114 integrally formed from the support surfaces 1111 and 1112 of the beam 111. Here, "inward" refers to the direction from the support surfaces 1111 and 1112 of the beam 111 towards the support foot 12. The specific method for integral forming can be to press out the inwardly recessed structures 1113 and 1114 from the support surfaces 1111 and 1112 of the beam 111 using a stamping process, but this is not limited to this method; for example, casting, forging, or 3D printing processes can also be used. It can be understood that the intermediate connecting structure 13 can also be an outwardly protruding structure integrally formed from the support foot 12. Here, "outward" refers to the direction from the support foot 12 towards the support surfaces 1111 and 1112 of the beam 111. The intermediate structure 13 is an integrally formed structure. Compared to separately formed structures, the gap G1 is generally smaller, making the integrally formed structure easier to fix and connect.

[0051] Optionally, reference may continue to be made to some embodiments of this application. Figure 3 as well as Figure 4 As shown, the specific structure of beam 111 can be as follows: beam 111 includes angle steel 1110, the inner plane of angle steel 1110 is the support surface 1111, 1112 of the beam, and there is a gap G1 between it and the support leg 12. The intermediate structure 13 includes inwardly recessed structures 1113, 1114 integrally formed from angle steel 1110. Angle steel 1110 has a first support portion 11101 and a second support portion 11102 that are perpendicular to each other. The support leg 12 has a first connecting portion 121 corresponding to the first support portion 11101 and a second connecting portion 122 corresponding to the second support portion 11102. The first connecting portion 121 and the second connecting portion 122 are perpendicular to each other. It can be understood that the perpendicularity here is not a strict 90°, but an approximate perpendicularity within the allowable error range.

[0052] The beam structure using angle steel is simple, has low material cost, and is easy to obtain. Furthermore, the process of creating the inwardly recessed structure 1113 and 1114 in the angle steel is simpler than the process of creating the outwardly protruding structure integrally formed in the support leg 12.

[0053] According to some embodiments of this application, optionally, reference is made to... Figure 2 As shown, the base frame 1 has at least two layers, for example... Figure 2 The two-layer structure shown includes an upper structure 101 and a lower structure 102. The upper structure 101 is located above the lower structure 102. The lower structure 101 includes a base 11 and supporting legs 12. The upper structure 101 includes beams 1011 supported by the supporting legs 12. It can be understood that multi-layer structures are not limited to... Figure 2The two-layer structure shown can also have more layers. The advantage of using a two-layer structure is that it can further improve the stability of its support, thereby enhancing the overall structural strength of the warehouse cage 10.

[0054] Optionally, reference may continue to be made to some embodiments of this application. Figure 2 As shown, the base 11 includes at least two first crossbeams 1101 and at least one longitudinal beam 1102. The first crossbeams 1101 are fixedly connected to the support legs 12 to support the support legs 12. The longitudinal beam 1102 connects the two first crossbeams 1101. Figure 2 As shown, the number of first crossbeams 1101 can be two first crossbeams 1101 and two longitudinal beams 1102, with the two first crossbeams 1101 and the two longitudinal beams 1102 surrounding to form a square base 11 structure. However, this is not a limitation; for example, the two first crossbeams 1101 and one longitudinal beam 1102 can also form an I-shaped base structure. The base 11 structure described in the above embodiment is relatively stable.

[0055] Optionally, reference may continue to be made to some embodiments of this application. Figure 2 As shown, the base 11 also includes a second crossbeam 1103, the height of which is the same as the support height of the support leg 12, to support the upper structure 101. The beams 1011 of the upper structure 101 include crossbeams 10111 and longitudinal beams 10112. The support leg 12 supports the crossbeams 10111 of the upper structure 101, and the second crossbeam 1103 supports the longitudinal beams 10112 of the upper structure 101. The specific structure can be... Figure 2 As shown, two second crossbeams 1103 are provided between the two first crossbeams 1101 of the base 11. The second crossbeams 1103 and the crossbeams 10111 supported by the support legs 12 jointly support six longitudinal beams 10112. It can be understood that the number of second crossbeams 1103 and longitudinal beams 10112 can be adjusted according to actual support needs and is not limited to the number shown in the figure. The structure of the base 11 described in the above embodiment is further stabilized and is conducive to adapting to larger loads.

[0056] Optionally, reference may continue to be made to some embodiments of this application. Figure 2 As shown, the specific locations of the support legs 12 are distributed in the corner areas of the base frame 1, for example... Figure 2 The base frame 1 is located at the four corners of the direction shown, and the support legs 12 are also connected to hooks 14. This facilitates the hoisting and transportation of the base frame 1 and the warehouse cage 10.

[0057] As described above, this application also provides a method for manufacturing a base frame 1 and a warehouse cage 10. The base frame 1 is the base frame described in the above embodiments, and the manufacturing method includes:

[0058] S1. A prefabricated component that fixes the base 11 and the support leg 12 together to form the base frame 1. The prefabricated component refers to the state in which the base frame 1 has fixedly connected the base 11 and the support leg 12, but has not yet undergone electroplating.

[0059] S2. Electroplating is performed on the prefabricated base frame 1 to obtain the processed part of the base frame 1. The processed part refers to the state after electroplating. Of course, it can also be that the mesh 2 of the warehouse cage and the base frame 1 are electroplated as a whole to obtain the processed part of the warehouse cage. Since the base frame 1 adopts a structure with a gap G1 between the support surfaces 1111 and 1112 of the beam 111 and the corresponding support feet 12, it avoids the problem of electroplating liquid accumulating in the surface-to-surface bonding structure and being difficult to flow out during the subsequent electroplating process due to the surface-to-surface bonding welding between the support surfaces of the beam 111 and the corresponding support feet 12, which leads to surface corrosion caused by the electroplating liquid seeping out after a period of time. The gap structure facilitates the smooth flow of electroplating liquid and avoids the problem of surface corrosion caused by the accumulation of electroplating liquid and seepage after a period of time, thereby improving the surface quality of the base frame and the warehouse cage.
