Description

Technical Field

[0001] This utility model relates to the field of warehouse racking technology, and in particular to an assembled metal warehouse racking system. Background Technology

[0002] Warehouse racking is an important tool for improving efficiency in modern warehouses, which has led to the emergence of the racking industry. Moreover, the market demand is increasing. With the rapid economic development, a large number of foreign-funded enterprises have entered the Yangtze River Delta and Pearl River Delta regions of my country, which has not only boosted the local economy but also brought new management concepts and technologies. As enterprises continue to increase production and expand their capacity, the standardization and efficiency of enterprise warehouses have naturally become a priority. Shelving generally refers to shelves for storing goods; racking is a storage device used to store packaged items.

[0003] For example, the modular metal storage rack disclosed in Chinese Patent No. CN217471512U works as follows: "It includes a rack base, side bars, L-shaped placement racks, and positioning bolts. Side bars are vertically welded to the four corners of the upper surface of the rack base. A hinge is installed on the inner bottom of each side bar. A sliding groove is formed on the side of each side bar away from the hinge. A movable block is fitted onto each side bar. A slider is provided on the inner side of each movable block, and the slider matches the sliding groove. Each movable block is connected to the others via L-shaped placement racks. Several [unclear text - possibly related to a specific type of rack] are formed on one side of each side bar." The positioning screw holes are provided on one side of each of the movable blocks, and the positioning bolts are matched with the through holes and positioning screw holes. This utility model allows for the disassembly of the shelving, changing its volume for easier assembly and handling. However, in actual assembly and disassembly operations, on the one hand, both processes rely on bolt connections, requiring workers to use specific tools, increasing the complexity of the operation and reducing efficiency. This is especially inconvenient in emergency situations or when frequently adjusting the shelving structure. On the other hand, small parts like bolts are easily lost after disassembly. Since the normal use of the shelving depends on the secure connection of its components via bolts, the loss of bolts prevents proper assembly, severely affecting its functionality and causing unnecessary trouble and losses in warehousing operations.

At the same time, the connecting components and the extension fixing components achieve the fixing and connection effect through a simple connection structure, which makes it easy for users to use and disassemble the rack quickly and conveniently, enhancing their work efficiency.

[0015] Specifically, the connecting components include a positioning block 24, a toothed plate 27, and a toothed rotating shaft 28. The fixing sleeve 22 has positioning grooves 23 around its perimeter. The short horizontal plate 13 and the long horizontal plate 14 are fixedly provided with positioning blocks 24 that cooperate with the positioning grooves 23 at both ends. The short horizontal plate 13 and the long horizontal plate 14 have rotating threaded grooves 25 at both ends. The rotating threaded groove 25 has a slot 26 on one side. The toothed plate 27 is connected to the slot 26 above it via a rotating shaft. The toothed rotating shaft 28 is installed inside the rotating threaded groove 25 below the toothed plate 27 via threads.

[0016] In this embodiment, positioning grooves 23 are provided around the fixed sleeve block 22, and positioning blocks 24 that cooperate with the positioning grooves 23 are provided at both ends of the short horizontal plate 13 and the long horizontal plate 14. This allows the short horizontal plate 13 and the long horizontal plate 14 to be quickly and accurately positioned on the fixed sleeve block 22 during assembly, improving assembly efficiency and accuracy and ensuring the stability of the shelf structure. Rotary threaded grooves 25 are provided at both ends of the short horizontal plate 13 and the long horizontal plate 14. A slot 26 is provided on one side of the rotary threaded groove 25 and a toothed plate 27 is connected through a rotating shaft. A toothed rotating shaft 28 is installed inside the rotary threaded groove 25. During the assembly process, the toothed rotating shaft 28 is rotated to cooperate with the installation threaded hole 21 to achieve initial fixation. At the same time, the toothed plate 27 can further tighten and enhance the connection strength, preventing the short horizontal plate 13 and the long horizontal plate 14 from loosening during use. This effectively improves the stability and reliability of the overall shelf structure and ensures the safety of goods storage.

[0017] Specifically, the extension fixing assembly includes a fixing shaft 210, a fixing block 18 fixedly mounted on the upper end of the fixing frame 11, and a fixing groove 17 opened at the lower end of the extension frame 12. A fixing groove 29 is opened through the fixing block 18 at the lower end of the extension frame 12. The fixing shaft 210 is movably mounted inside the fixing groove 29. A limiting groove 211 is opened at one end of the fixing shaft 210. Several elastic grooves are opened inside the limiting groove 211, and elastic elements are installed inside the grooves. A connecting shaft 212 is movably mounted inside the limiting groove 211. The connecting shaft 212 is fixedly connected to the elastic elements through the connecting block. The other end of the connecting shaft 212 is rotatably connected to a limiting plate 213. A limiting groove 214 is opened on the side of the fixing groove 29 at the lower end of the extension frame 12.

[0018] In this embodiment, a fixing block 18 is provided at the upper end of the fixing frame 11, and a fixing groove 17 and a fixing groove 29 are provided at the lower end of the extension frame 12. The fixing shaft 210 is movably disposed inside the fixing groove 29, so that the extension frame 12 can be stably connected to the fixing frame 11 to extend the shelf height. A limiting groove 211 is provided at one end of the fixing shaft 210, and an elastic element and a connecting shaft 212 are provided in the limiting groove 211. The other end of the connecting shaft 212 is rotatably connected to the limiting plate 213. During installation, the fixing shaft 210 is inserted into the fixing groove 29. After step 29, the elastic element pushes the connecting shaft 212, causing the limiting plate 213 to pop out and lock into the limiting groove 214. This effectively prevents the fixed shaft 210 from falling off during use, ensuring the firmness of the connection between the extension rack 12 and the fixed rack 11. At the same time, it is also easy to disassemble. When it is necessary to adjust the height of the shelf or to store it, simply operate the limiting plate 213 to compress the elastic element of the connecting shaft 212, and the fixed shaft 210 can be easily removed, realizing the separation of the extension rack 12 and the fixed rack 11. The operation is convenient and quick, improving the flexibility and convenience of the shelf use.

The spring is sleeved on the outside of the fixed post. The connecting block is movably sleeved on the outside of the fixed post, and the connecting block is fixedly connected to one end of the connecting shaft 212.

[0020] Specifically, the length of the fixing frame 11 is less than half the length of the mounting groove 20, and the base plate 10 has placement compartments 15 on both sides for placing the short horizontal plate 13 and the long horizontal plate 14.

[0021] In this embodiment, the length of the fixing frame 11 is less than half the length of the mounting slot 20, so that the fixing frame 11 can be completely stored in the mounting slot 20 when folded and stored, further reducing the space occupied by the shelf after storage, and facilitating transportation and storage. Placement compartments 15 are opened on both sides of the base plate 10. When the short horizontal plate 13 and the long horizontal plate 14 are not used, they can be placed in the placement compartments 15 to avoid the loss of parts. At the same time, the shelf as a whole is more neat and orderly, and easier to manage and use. This design fully considers the needs of the shelf under different usage conditions and improves the practicality and convenience of the shelf.

[0022] Specifically, the rotating threaded groove 25 has threads inside that are opposite to those in the mounting threaded hole 21.

[0023] In this embodiment, when assembling the shelf, when using bolts or other connectors to connect and fix the shelf through the mounting threaded holes 21 and rotating threaded grooves 25, the opposite thread directions enable the connectors to lock together when subjected to external forces, effectively preventing the connectors from loosening. This further enhances the connection strength between the short horizontal plate 13, the long horizontal plate 14 and the fixed frame 11 or the extension frame 12, improving the stability and reliability of the overall shelf structure, ensuring that the shelf remains stable when carrying goods, and guaranteeing the safety of goods storage.
