[0001] This utility model relates to the field of storage rack technology, and more particularly to a storage rack for items in the supply chain. Background Technology
[0002] In modern supply chain management systems, efficient storage and circulation of goods are crucial for ensuring smooth supply chain operation. With the continuous expansion of supply chain scale and the increasing complexity of goods, traditional goods placement racks are no longer sufficient to meet the growing logistics demands. A search revealed a Chinese patent with authorization announcement number CN221795799U, which discloses a goods placement rack for supply chains. The rack includes a base, a rack body fixedly connected to the top of the base, a support plate fixedly connected to the top of the base, a second hydraulic rod fixedly connected to the front of the support plate, a support rod fixedly connected to one end of the second hydraulic rod, and a support seat fixedly connected to one end of the support rod. This goods placement rack for supply chains, through its first hydraulic rod, slide rail, telescopic rack body, platform, rack body, second hydraulic rod, slider, and support rod, allows for assisted lifting of workers when retrieving or storing items from higher locations. This eliminates the need to move ladders, benches, or other items to increase height, providing convenience for workers in retrieving and placing items and further improving work efficiency.
[0003] The aforementioned patent for a shelf for placing items in a supply chain has the following drawbacks: the device uses a first hydraulic rod and a second hydraulic rod to facilitate the retrieval and placement of items that are high up, but the hydraulic rods require an additional hydraulic system to provide power. Since there are generally many shelves in the supply chain, such production costs are not conducive to the promotion and use of this shelf. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a goods storage rack for the supply chain.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A storage rack for a supply chain includes a rack frame. Two vertical plates are fixedly connected to the middle of the bottom inner side of the rack frame. Each vertical plate has a vertical groove on one side of its top. A positioning rod is fixedly connected between the top and bottom of each vertical groove. The same slider is slidably fitted onto the circumferential surface of the two positioning rods. Both sliders have circular holes that match the positioning rods. A single iron U-shaped frame is rotatably connected to the outer side of the two sliders. Handles are fixedly connected to both ends of the outer side of the two iron U-shaped frames. Pulling the handles allows the iron U-shaped frames to be extended and retracted easily. Multiple support rods are fixedly connected at equal intervals between the iron U-shaped frames. Frame sleeves are fixedly connected to both ends of the bottom of the rack frame near the iron U-shaped frames. Magnet blocks are fixedly embedded inside the two frame sleeves. The magnet blocks help to further secure the retracted iron U-shaped frames, preventing them from easily sliding out and obstructing the user's work.
[0006] Preferably, a rectangular groove is provided at the bottom of the inner side of the shelf frame at the two vertical plates, and two guide rods are fixedly connected between the two ends of the rectangular groove.
[0007] Preferably, the same rectangular block is slidably fitted onto the circumferential surface of the two guide rods, and both ends of the rectangular block are provided with circular holes that are adapted to the guide rods.
[0008] Preferably, both ends of the top of the rectangular block are fixedly connected to connecting rods, and the other ends of the two connecting rods are rotatably connected to one side of the bottom of the iron U-shaped frame.
[0009] Preferably, multiple third placement plates are fixedly connected at equal intervals between the two vertical plates, and the third placement plates are adapted to the support rods. The arrangement of multiple third placement plates allows the space at the iron U-shaped frame to be utilized without wasting space.
[0010] Preferably, the tops of the two vertical plates are fixedly connected to the same top plate, and the two ends of the top plate are fixedly connected to the inside of the shelf frame. The inner wall of the shelf frame is fixedly connected with a plurality of first placement plates at equal intervals at the top of the top plate.
[0011] Preferably, multiple side placement plates are fixedly connected at equal distances on the sides of the two vertical plates that are far apart from each other, and the other end of each side placement plate is fixedly connected to the inside of the shelf frame. Support legs are fixedly connected to both ends of the bottom of the shelf frame.
[0012] The beneficial effects of this utility model are as follows: By employing technologies such as iron U-shaped frames, support rods, positioning rods, guide rods, and connecting rods, the iron U-shaped frames can be folded up and fit snugly against the shelf under normal circumstances. When needed, the iron U-shaped frames can be pulled out using the handles, transforming them into a ladder shape, allowing users to easily climb and retrieve items. This convenient unfolding and folding effectively solves the problem of high production costs mentioned in the background technology, enabling the iron U-shaped frames to be quickly unfolded and folded up. This gives the shelf both storage and accessibility functions, improving the flexibility and responsiveness of supply chain operations and ensuring the efficient operation of the supply chain.
