Description

Technical Field

[0001] This utility model relates to the field of storage cage technology, and in particular to a foldable storage cage. Background Technology

[0002] Storage cages are an important warehousing and logistics tool that plays a key role in multiple stages of warehousing, transportation, and production. They enable the classified storage of goods, facilitate the transfer of goods in whole cages, and improve the space utilization of factory buildings by stacking multiple storage cages.

[0003] The structure of the storage cage consists of a perimeter enclosure formed by multiple mesh-like side units, and a load-bearing base for sealing the bottom of the perimeter enclosure. The problem with existing storage cages is that the load-bearing base and perimeter enclosure are a single unit (connected by welding), which occupies a large amount of factory space when the storage cage is unloaded. Therefore, a foldable storage cage needs to be designed to solve this problem. Utility Model Content

[0007] Preferably, the side unit includes a mesh plate and shaft cylinders on both sides of the mesh plate. The shaft cylinders of the two mesh plates that are rotatably connected are staggered and connected by a through-core shaft.

[0008] Preferably, a top sealing ring is provided near the upper end of the through shaft, and the bottom of the through shaft is locked in position by being inserted into the receiving hole of the bearing base.

[0009] Preferably, the bottom of the side unit is provided with an extension edge, and by fixing the extension edge to the side wall of the bearing substrate, a stable connection between the surrounding enclosure structure and the bearing substrate is achieved.

[0010] Preferably, the supporting base is provided with a receiving hole, and a plurality of the side units are rotatably connected by a through shaft.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0023] This utility model provides a foldable storage cage, see reference. Figures 2-5 The enclosure mainly consists of two parts: a detachable perimeter enclosure structure 7 and a load-bearing base. When connected to the load-bearing base, the perimeter enclosure structure 7 maintains a stable, defined storage space, allowing for the storage of goods. When separated from the load-bearing base, the perimeter enclosure structure 7 can be folded due to the rotatable connection of its several side units 1, thus reducing its space occupation when idle. The perimeter enclosure structure 7 has several side units 1. These side units 1, when rotatably connected, form a closed shape that is not stable in geometric force analysis. For example, the top view of three side units 1 connected by rotation forms a triangle. Triangles are stable and therefore cannot be folded. Therefore, the top view of the perimeter enclosure structure 7 is a closed shape (excluding the case of three side units 1) formed by several side units 1 connected by rotation, which is not stable (a closed shape indicates at least three side units 1). This can be interpreted as at least four side units 1 constituting the perimeter enclosure structure 7.

[0024] Furthermore, in order to enable those skilled in the art to clearly understand how the surrounding enclosure structure 7 is specifically folded, first refer to... Figure 1The peripheral enclosure structure 7 comprises several side units 1 (no fewer than four). Each side unit 1 has a shaft sleeve 2 fixedly connected to both sides. The shaft sleeves 2 of adjacent side units 1 are staggered. When the shaft sleeves 2 of adjacent side units 1 are aligned vertically, a through-shaft rod 3 passes through the shaft sleeves 2 of the two adjacent side units 1, thus connecting the two side units 1. To prevent the two side units 1 from detaching from the through-shaft rod 3, a top sealing ring is provided near the top of the through-shaft rod 3. Similarly, a bottom sealing ring can be selectively provided at the bottom of the through-shaft rod 3 (optional). The bottom sealing ring primarily prevents the side units 1 from detaching from the bottom of the through-shaft rod 3. The top and bottom sealing rings can be fixed to the through-shaft rod 3 by welding after the through-shaft rod 3 passes through the shaft sleeves 2 of the two adjacent side units 1, or by thread or other stable connection methods. See the detailed reference. Figure 6 and Figure 7 , Figure 6 This is a top view of multiple side units 1 in the open state, i.e., the shape of the surrounding enclosure structure 7 when it is not folded. Figure 7 A schematic diagram of the folding process of multiple side units 1 of the surrounding enclosure structure 7.

[0025] To enable those skilled in the art to understand the specific implementation of this utility model, two specific embodiments will be provided below to illustrate the above-mentioned solution in detail.

[0026] The first embodiment provided by this utility model is as follows: Figure 2 and Figure 3 As shown, the bottom of the side unit 1 of the aforementioned perimeter enclosure structure 7 is provided with an extension flange 5. When the perimeter enclosure structure 7 (shown in the diagram of four side units 1) is in the open state, the bottom of the perimeter enclosure structure 7 is aligned with the bearing base 8. At this time, the extension flange 5 is aligned with the side wall of the bearing base 8. The extension flange 5 is then detachably connected to the side wall of the bearing base 8 using a fixing device, specifically, fixing bolts 10 can be used. Figure 2 In the middle, a through hole is provided on the extension edge 5, and a threaded hole 13 is provided on the bearing base 8. After the fixing bolt 10 passes through the through hole, it is threaded into the threaded hole 13 on the bearing base 8, so as to achieve the following Figure 3 As shown, the perimeter enclosure structure 7 and the supporting base 8 are detachably connected, and after the perimeter enclosure structure 7 and the supporting base 8 are connected, the position of the side unit 1 is locked, so the stability of the accommodating space can be guaranteed.

[0027] Furthermore, in order to further ensure the stability of the accommodating space, the four corners of the bearing base 8 of the first embodiment (corresponding to the examples of the four side units 1 above) are provided with accommodating holes 9, each accommodating hole 9 corresponding to the bottom of accommodating a through shaft 3, thereby further ensuring the stability of the accommodating space.

[0028] A second embodiment of this utility model is, for example... Figure 4 and Figure 5 As shown, the difference between the second embodiment and the first embodiment is that the bottom of the side unit 1 of the peripheral enclosure structure 7 does not have an extension edge 5, and the connection method between the peripheral enclosure structure 7 and the bearing base 8 is also different from that in the first embodiment. In the second embodiment, the four corners of the bearing base 8 (corresponding to the schematic examples of the four side units 1 in the above and attached figures, the specific positions and numbers are not limited) are also provided with receiving holes 9. The overall length of the receiving holes 9 is relatively short. The bottom of the through shaft 3 passes through the receiving hole 9 and continues to extend downward for a certain distance. The bottom of the through shaft 3 is also provided with a threaded part 301. By threading the nut 11 into the threaded part 301, the through shaft 3 and the bearing base 8 are fixed. That is, before the peripheral enclosure structure 7 is connected to the bearing base 8, as shown in the figure... Figure 4 As shown, after the surrounding enclosure structure 7 is connected to the load-bearing base 8, it is as follows: Figure 5 As shown, the position of the through shaft 3 is relatively fixed at this time, thus ensuring the stability of the accommodating space.

[0029] In both of the above embodiments, a pad 12 can be provided at the bottom of the support base 8. The function of the pad 12 is to provide the bottom of the support base 8 with an operating space for inserting the arm, while maintaining the stability of the center of gravity of the storage cage, thereby facilitating the forklift to transfer the storage cage.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above-described embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
