Description

Technical Field

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

[0002] In modern logistics warehousing, supermarket retail, and industrial production workshops, shelving serves as the core equipment for storing and circulating materials, and its performance directly affects space utilization, operational efficiency, and management costs.

[0003] While traditional fixed racking systems are structurally robust and have strong load-bearing capacity, they are difficult to move once installed, lacking necessary flexibility. This exposes significant limitations in applications requiring frequent adjustments to warehouse layout, optimization of goods access routes, or temporary and seasonal warehousing allocations. The rigid structure of fixed racking systems leads to fixed warehouse functional zoning, making it difficult to adapt to dynamically changing warehousing needs. This not only wastes space resources but also significantly reduces the responsiveness and overall efficiency of the logistics system.

[0004] Currently, existing shelving systems mostly use bolts or welding to connect the support base to the upper storage rack. The assembly and disassembly process is cumbersome and requires special tools. This not only increases the time and labor costs for initial installation and subsequent maintenance, but also results in low modularity and standardization of the shelving, which is not conducive to large-scale production and transportation.

[0005] Therefore, in response to the above problems, the applicant needs to design a modular mobile shelving system to solve the problem. Utility Model Content

[0006] This application provides a prefabricated mobile shelf, including a support base and a storage shelf. The bottom surface of the support base is fixedly provided with a plurality of casters. The support base has mounting holes. The top surface of the support base is provided with a locking mechanism, which cooperates with the mounting holes for assembling the storage shelf and the support base. The locking mechanism includes a clamping block, and a connecting lug is fixedly provided on the clamping block. A sliding rod is rotatably provided inside the connecting lug, and a rotating compartment is fixedly provided on the surface of the sliding rod. A fixed shaft is fixedly provided inside the rotating compartment, and a hollow sleeve is rotatably provided outside the fixed shaft. An extension rod is slidably provided inside the hollow sleeve, and the end of the extension rod away from the hollow sleeve passes through the support base.

[0007] Preferably, a fixing spring is provided in the cavity between the hollow sleeve and the extension rod. The fixing spring provides an automatic reset function, ensuring that the extension rod can quickly return to its initial position when no force is applied, thereby enhancing the stability and reliability of the locking mechanism.

[0008] Preferably, the extension rod has a limiting hole, and the bottom surface of the support base is fixedly provided with a reinforcing mechanism. The reinforcing mechanism cooperates with the limiting hole to lock the support base and the storage shelf. The reinforcing mechanism further locks the support base and the storage shelf through the limiting hole, thereby improving the stability and safety of the overall structure.

[0009] Preferably, the reinforcement mechanism includes a fixing block fixedly connected to the bottom surface of the support base, and a sliding sleeve is fixedly provided on the inner side of the fixing block. A locking rod is slidably provided on the inner side of the sliding sleeve, and the locking rod is adapted to the limiting hole. The sliding sleeve and the locking rod make the operation of the reinforcement mechanism simple and smooth, and facilitate quick locking and unlocking.

[0010] Preferably, a handle is fixedly provided at one end of the locking rod, and a return spring is fixedly provided on one side of the handle. The end of the return spring away from the handle is fixedly connected to the fixing block. The return spring causes the locking rod to automatically return to its original position after being released, which simplifies the operation steps and improves the ease of use.

[0011] Preferably, at least two rubber blocks are fixedly disposed above the clamping block, and the rubber blocks are interference-fitted with the rotating chamber, so that the rubber blocks can easily clamp and store the rotating chamber through the interference fit.

[0012] Preferably, the clamping surface of the clamping block is bonded with a gasket, and the gasket is made of silicone rubber. The silicone rubber gasket increases the friction coefficient of the clamping surface, preventing the shelf uprights from slipping or wearing during the clamping process.

[0013] Preferably, the top surface of the support base is provided with anti-slip texture. The anti-slip texture increases the friction of the top surface of the support base, prevents the goods from sliding on the support base, and ensures the stability of the assembly.

[0014] This utility model provides a prefabricated mobile shelving unit, which, compared with the prior art, has the following advantages: This prefabricated mobile shelving unit achieves tool-free, rapid assembly and disassembly by using a rotating compartment to drive an extension rod that clamps the shelving uprights and forms a quick clamping mechanism with the clamping blocks. This improves assembly efficiency. Furthermore, the automatic engagement and locking of the extension rod's limiting hole and the reinforcing mechanism's locking rod under the action of a return spring provides double protection against loosening. The unit is easy to assemble and highly stable, thus enhancing the connection stability and overall safety of the shelving unit during movement and under load. Attached Figure Description

Detailed Implementation

[0018] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0019] Please refer to Figures 1-5This utility model provides a prefabricated mobile shelf, including a support base 1 and a storage shelf 10. The bottom surface of the support base 1 is fixedly provided with several casters 11. The support base 1 has mounting holes 12, and the top surface of the support base 1 is provided with a locking mechanism 2. The locking mechanism 2 cooperates with the mounting holes 12 for assembling the storage shelf 10 and the support base 1. The locking mechanism 2 includes a clamping block 20, and a connecting lug 21 is fixedly provided on the clamping block 20. A sliding rod 22 is rotatably provided inside the connecting lug 21, and a fixed surface is provided on the sliding rod 22. The rack has a rotating compartment 23, with a fixed shaft 24 fixedly installed inside. A hollow sleeve 25 is rotatably installed on the outside of the fixed shaft 24. An extension rod 26 is slidably installed on the inside of the hollow sleeve 25, and the end of the extension rod 26 away from the hollow sleeve 25 passes through the support base 1. The locking mechanism 2 can quickly clamp and fix the rack uprights by simply pressing down, which simplifies the assembly and disassembly process, requires no tools, improves the assembly efficiency and mobility of the rack, and solves the problem of cumbersome and time-consuming traditional bolt connection or welding methods.

[0020] To enhance the reset function and ensure that the extension rod 26 can quickly return to its initial position when no force is applied, a fixing spring is installed in the cavity between the hollow sleeve 25 and the extension rod 26.

[0021] like Figure 4 and Figure 5 As shown, the extension rod 26 has a limiting hole 27. The bottom surface of the support base 1 is fixedly provided with a reinforcing mechanism 3, and the reinforcing mechanism 3 cooperates with the limiting hole 27 to lock the support base 1 and the storage shelf 10. The reinforcing mechanism 3 includes a fixing block 30 fixedly connected to the bottom surface of the support base 1, and a sliding sleeve 31 is fixedly provided inside the fixing block 30. A locking rod 32 is slidably provided inside the sliding sleeve 31, and the locking rod 32 is adapted to the limiting hole 27. A handle 33 is fixedly provided at one end of the locking rod 32, and a return spring 34 is fixedly provided on one side of the handle 33. The end of the return spring 34 away from the handle 33 is fixedly connected to the fixing block 30. When the extension rod 26 of the locking mechanism 2 extends downward and locks, the limiting hole 27 on its surface will move to the position corresponding to the reinforcing mechanism 3. At this time, under the push of the return spring 34, the locking rod 32 will be horizontally embedded in the limiting hole 27 of the extension rod 26, forming a mechanical interlock.

[0022] In order to clamp and store the rotating chamber 23, at least two rubber blocks 28 are fixedly provided above the clamping block 20, and the rubber blocks 28 are interference fit with the rotating chamber 23.

[0023] The clamping surface of the clamping block 20 is bonded with a gasket, and the gasket is made of silicone rubber, which increases the coefficient of friction of the clamping surface and improves stability.

[0024] To prevent the goods from sliding on the support base 1, the top surface of the support base 1 is provided with anti-slip texture.

[0025] In summary, during installation, the uprights of the storage rack 10 are inserted into the mounting holes 12 of the support base 1. Through the rotating chamber 23 of the locking mechanism 2, the hollow sleeve 25 is driven to rotate using the lever principle, which in turn presses the internal extension rod 26. This causes the extension rod to overcome the elastic force of the fixed spring and extend downwards to press against the uprights of the rack. This, in conjunction with the clamping block 20, quickly clamps and fixes the uprights from both sides. At the same time, when the extension rod 26 moves down to a specific position, the limiting hole 27 on it aligns with the locking rod 32 of the reinforcing mechanism 3. Under the action of the return spring 34, the locking rod 32 automatically embeds into the limiting hole 27 to form a mechanical interlock, thereby locking the position of the extension rod 26. This constitutes a double insurance against loosening, ultimately achieving a tool-free, quick, and reliable connection between the support base 1 and the storage rack 10.

[0026] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
