Description

Technical Field

[0001] This utility model belongs to the field of storage racks, specifically, it relates to an easy-to-fold storage rack. Background Technology

[0002] With the increasing variety and specifications of products on the market, product racks must be able to adapt to the storage needs of products of different shapes, sizes, and weights, leading to a diversification of rack designs. For example, some products may require greater load-bearing capacity, while others may require specific shapes and support structures to prevent damage. Traditional racks often have design limitations when facing such diverse needs. Many existing fixed racks cannot be adjusted or modified, not only occupying a lot of space but also making it difficult to store different products, especially during the production process. Due to a lack of flexibility and limited rotation capabilities, they cannot adapt to rapidly changing shipping requirements. Meanwhile, another type of traditional rack is the detachable structure. Although it provides flexibility to some extent, its complex disassembly and assembly, cumbersome operation, and long assembly time lead to low work efficiency, and may affect the stability and durability of the structure after long-term use.

[0003] In view of this, this utility model is proposed. Utility Model Content

A tapered guide post is fixedly connected to the upper end of each column. A slot adapted to the tapered guide post is provided below the column. A baffle for placing the folded column is fixedly connected to the middle part of both sides of the lower frame. A connecting block is fixedly connected to one side of each column. A connecting rod is fixedly connected above the connecting block. Through holes adapted to the connecting rod are provided at the four corners of opposite sides of the upper frame.

[0007] Optionally, the upper frame includes two composite rods, and multiple fixing rods are provided above the two composite rods. Nylon strips are fixedly connected to the top of the fixing rods by bolts.

[0008] Optionally, the lower frame includes two rods, with a positioning rod between the two rods, and two lifting rings fixedly connected to one side of the positioning rod.

[0009] Optionally, a through hole is provided on the opposite side of the column, and a through groove corresponding to the through hole is provided on the opposite side of the positioning rod, with a rotating shaft inserted into the inside of the through hole.

[0010] Optionally, one end of the rotating shaft is fixedly connected to a screw rod passing through the through groove, and one end of the screw rod is threadedly connected to a nut that fits against one side of the positioning rod.

[0011] Optionally, shock-absorbing rings are fixedly connected to both the upper and lower ends of the column, with the shock-absorbing ring at the upper end of the column sleeved around the periphery of the tapered guide column, and the shock-absorbing ring at the lower end of the column matching the groove.

[0012] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0013] The purpose of this invention is to reduce space waste and facilitate transportation by folding the storage rack.

Detailed Implementation

[0020] The present invention will now be described in further detail with reference to the accompanying drawings.

[0021] Please see Figure 1-3As shown, this embodiment provides a foldable storage rack, including a lower frame 3 and an upper frame 4 located above the lower frame 3. Columns 9 are rotatably connected to the edges of both sides of the lower frame 3. A tapered guide post 1 is fixedly connected to the upper end of each column 9. A slot 10 matching the tapered guide post 1 is provided below each column 9. Baffles 7 for placing the folded columns 9 are fixedly connected to the middle parts of both sides of the lower frame 3. A connecting block 17 is fixedly connected to one side of each column 9. A connecting rod 11 is fixedly connected above the connecting block 17. Through holes matching the connecting rod 11 are provided at the four corners of the opposite sides of the upper frame 4. This invention, by providing rotatable columns 9 on both sides of the lower frame 3, and a tapered guide post 1 at the upper end of each column 9, with a matching slot 10 at the lower end, makes the folding and unfolding process smoother, automatically aligning without additional adjustments. When folded, the columns 9 rotate inward, and the tapered guide post 1 embeds into the slot 10, ensuring a compact structure after folding and reducing space occupation by approximately 65%. In addition, the design of connecting block 17 and connecting rod 11 allows the upper frame 4 to be quickly installed or disassembled, with the entire operation taking only 1 to 2 minutes, greatly improving assembly efficiency and making it suitable for logistics scenarios with frequent disassembly and assembly.

[0022] In this embodiment, the upper frame 4 includes two combined rods 12, and multiple fixing rods 13 are arranged above the two combined rods 12. Nylon strips 8 are fixedly connected to the upper part of the fixing rods 13 by bolts. The nylon strips 8 form a flexible support surface. The spacing of the nylon strips 8 can be flexibly adjusted according to the product size and shape to avoid scratches on the product surface caused by hard contact.

[0023] In this embodiment, the lower frame 3 includes two rods 14, with a positioning rod 15 positioned between the two rods 14. Two lifting rings 5 ​​are fixedly connected to one side of the positioning rod 15. The lower frame 3 in this embodiment adopts a double-rod 14 structure with a reinforcing positioning rod 15 in the middle, significantly improving the overall load-bearing capacity. A single layer can bear up to 600 kg, meeting the storage requirements of heavy industrial parts. The lifting rings 5 ​​on both sides of the positioning rod 15 are designed for easy lifting by forklifts or cranes.

[0024] In this embodiment, a through hole is provided on the opposite side of the column 9, and a through groove corresponding to the through hole is provided on the opposite side of the positioning rod 15. A rotating shaft 6 is inserted into the inside of the through hole. In this embodiment, through holes and through grooves are provided on the column 9 and the positioning rod 15, and they are connected by a rotating shaft 6, so that the column 9 can rotate freely 180° along the axis, realizing quick folding or unfolding.

[0025] In this embodiment, one end of the rotating shaft 6 is fixedly connected to a screw rod passing through the through groove, and one end of the screw rod is threadedly connected to a nut 16 that fits against one side of the positioning rod 15. The rotating shaft 6 is provided with a screw rod and a nut 16 at one end, and the column 9 is fixed by the threaded locking method. In addition, the nut 16 can also effectively prevent the rotating shaft 6 from falling off in the future.

[0026] In this embodiment, shock-absorbing rings are fixedly connected to both the upper and lower ends of the column 9. The shock-absorbing ring at the upper end of the column 9 is sleeved around the periphery of the tapered guide column 1, and the shock-absorbing ring at the lower end of the column 9 is adapted to fit the groove 10. In this embodiment, shock-absorbing rings are provided at both the upper and lower ends of the column 9. The upper shock-absorbing ring is sleeved around the tapered guide column 1, and the lower shock-absorbing ring is tightly fitted with the groove 10, forming a double buffer structure. The shock-absorbing rings can reduce the impact force during splicing.
