Description

Technical Field

[0001] This utility model relates to the field of warehouse racking technology, and in particular to a warehouse racking with adjustable column span. Background Technology

[0002] As a core facility in modern logistics warehousing systems, storage racks are widely used in various warehouses, workshops, and supermarkets to store goods, achieving efficient space utilization and standardized management. With the diversification of market demands and the continuous changes in the specifications of stored goods, higher requirements are being placed on the flexibility, adaptability, and economy of storage racks.

[0003] Currently, most warehouse racking systems on the market, especially medium and heavy-duty racking, use a fixed-size design for their main structure. This means the column spacing (span) is determined at the factory and cannot be adjusted according to changes in the actual warehouse layout or the size of the stored goods. This fixed-span design has the following significant drawbacks: when the size of the goods to be stored is special, or when the warehouse layout changes, the fixed-span racking cannot be adjusted, potentially leading to wasted space or failure to meet storage needs. Users often need to purchase racking of specific sizes, increasing operating costs. To cope with the storage requirements of different sized goods, users typically need to stock multiple racking systems with different spans, which not only increases initial procurement costs but also consumes a significant amount of warehouse space and management effort. Therefore, this paper proposes an adjustable-span warehouse racking system to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to propose a warehouse rack with adjustable column span to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0006] To achieve the above objectives, one embodiment of the present invention provides an adjustable column span storage rack, including a base, a main sleeve, and a telescopic section. The main sleeve is fixedly connected to the side of the base, and the telescopic section is movably connected inside the main sleeve. The end of the telescopic section is fixedly connected to another base.

[0007] The spacing between the bases is adjustable, and the top surface of the main sleeve is threaded with a fastening pin, the bottom end of which abuts against the end of the top surface of the telescopic section.

[0008] The top of the base is fixedly connected to a column, and the column has several positioning holes.

[0009] The support frame is detachably connected to the surface of the column. The support frame is X-shaped in general. The end of the support frame is provided with a long strip-shaped guide groove. A threaded pin is movably connected to the center of the support frame.

[0010] The outer surface of the threaded pin is threaded with fasteners.

[0011] A threaded pin is inserted into the guide groove and the corresponding positioning hole, and a fastener is threaded onto the outer surface of the threaded pin.

[0012] The uprights have several sets of hanging holes on their sides, arranged in groups of three. Each hanging hole has a hook, and a shelf is fixedly connected to the front of each hook. The shelf length is selectable and matches the spacing between the bases. This shelving system utilizes a sliding design for the main frame and telescopic sections, allowing continuous adjustment of the spacing between the bases to adapt to different warehouse spaces and varying product sizes, thus improving the shelving's versatility and applicability. Users do not need to purchase multiple fixed-size shelves, saving costs. This shelving system is highly stable and safe: a fastening pin mechanism ensures that the telescopic sections remain securely fixed, preventing shelf deformation; the X-shaped structure and threaded pin connection of the support frame enhance overall rigidity and reduce swaying; the uprights are firmly welded to the base, and the linear array of positioning holes ensures even stress distribution and strong load-bearing capacity.

[0013] Preferably, in any of the above solutions, the base is connected to the end of the main sleeve by screws, and the base is connected to the end of the telescopic section by screws.

[0014] The above technical solution is adopted: the span of the uprights of this warehouse rack is adjustable, that is, the length of this rack is adjustable. After adjustment, a matching shelf is hung to place different types of goods.

[0015] Preferably, of any of the above solutions, the main sleeve is hollow and the material of the main sleeve is stainless steel.

[0016] Preferably, in any of the above solutions, the column is welded to the base, and the positioning holes are linearly arrayed on the column.

[0017] Preferably, the fastener is a washer-type nut, which is one of the above-mentioned solutions.

[0018] Preferably, the hooks and shelves are made of aluminum alloy and are integrally formed. The working principle of this adjustable column span storage rack is based on its adjustable column span design. The core components of the rack include a base, main sleeve, telescopic section, fastening pins, uprights, positioning holes, support frames, guide grooves, threaded pins, fasteners, hanging holes, hooks, and shelves. During operation, the distance between the two bases (i.e., the rack length) is first changed by adjusting the position of the telescopic section within the main sleeve. The telescopic section is movably connected inside the main sleeve, and its end is fixedly connected to another base; sliding the telescopic section allows for continuous adjustment of the span. After adjusting to the desired span, the fastening pins on the top surface of the main sleeve are tightened, so that the bottom end of the fastening pin abuts against the end of the top surface of the telescopic section, thereby fixing the position of the telescopic section and ensuring span stability. The uprights are fixed to the top of the base and have multiple positioning holes for installing the support frames. The support frame is X-shaped with elongated guide slots at its ends. By aligning the guide slots with the positioning holes on the uprights, inserting threaded pins, and threading fasteners (such as washer nuts) onto the outer surface of the threaded pins, the support frame can be detachably fixed to the uprights, providing lateral support. Shelves are attached to hanging holes on the side of the uprights via hooks, with three hooks per group, allowing for flexible adjustment of the shelf height and position. The shelf length can be matched to the adjusted base spacing to ensure stable load-bearing. The entire rack system, through adjustable span and modular assembly, adapts to the storage needs of different goods.

[0019] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0020] This adjustable-span storage rack features a sliding design for the main frame and telescopic sections, allowing for continuous adjustment of the base spacing. This adapts to varying warehouse spaces and product sizes, enhancing the rack's versatility and applicability. Users no longer need to purchase multiple fixed-size racks, saving costs. The rack boasts high stability and safety: a fastening pin mechanism ensures the telescopic sections remain securely fixed, preventing deformation; the X-shaped support structure and threaded pin connections enhance overall rigidity and reduce swaying; the uprights are firmly welded to the base, and the linear array of positioning holes ensures even stress distribution and strong load-bearing capacity.

[0030] like Figure 1-4 As shown, this adjustable-span storage rack includes a base 1, a main sleeve 2, and a telescopic section 3. The main sleeve 2 is fixedly connected to the side of the base 1, and the telescopic section 3 is movably connected inside the main sleeve 2. The end of the telescopic section 3 is fixedly connected to another base 1. The main sleeve 2 is hollow, and the hollowness of the main sleeve 2 matches the telescopic section 3. The main sleeve 2 is fitted on the outer surface of the telescopic section 3, and the telescopic section 3 can move inside the main sleeve 2.

[0031] The spacing between the bases 1 is adjustable. The top surface of the main sleeve 2 is threaded with a fastening pin 4, and the bottom end of the fastening pin 4 abuts against the end of the top surface of the telescopic section 3.

[0032] A column 5 is fixedly connected to the top of the base 1, and several positioning holes 6 are provided on the column 5;

[0033] The support frame 7 is detachably connected to the surface of the column 5. The support frame 7 is X-shaped in general. The end of the support frame 7 is provided with a long strip-shaped guide groove 8. The center of the support frame 7 is movably connected with a threaded pin 9.

[0034] The outer surface of the threaded pin 9 is threaded with fastener 10;

[0035] A threaded pin 9 is inserted into the guide groove 8 and the corresponding positioning hole 6. A fastener 10 is threadedly connected to the outer surface of the threaded pin 9.

[0036] The side of the column 5 has several sets of hanging holes 11, with three hanging holes 11 in each group. A hook 12 is hung on the hanging hole 11, and a shelf 13 is fixedly connected to the front of the hook 12. The length of the shelf 13 is selectable and matches the spacing of the base 1.

[0037] Example 1: The base 1 and the main sleeve 2 are connected at their ends by screws, and the base 1 and the telescopic section 3 are also connected at their ends by screws. The main sleeve 2 is hollow and made of stainless steel. The column 5 is welded to the base 1, and the positioning holes 6 are linearly arrayed on the column 5. The fastener 10 is specifically a washer-loaded nut. The hook 12 and shelf 13 are made of aluminum alloy and are integrally formed.

[0038] Example 2: In this warehouse racking system, the span of the uprights 5 is adjustable, meaning the length of the racking system is adjustable. After adjustment, shelves 13 of matching length are hung to hold different types of goods. The uprights 5 are welded to the base 1, and the positioning holes 6 are linearly arrayed on the uprights 5. The fasteners 10 are specifically nut-type fasteners with washers. The working principle of this adjustable upright span warehouse racking system is based on its adjustable upright span design. The core components of the racking system include the base 1, main sleeve 2, telescopic section 3, fastening pin 4, uprights 5, positioning holes 6, support frame 7, guide groove 8, threaded pin 9, fastener 10, hanging hole 11, hook 12, and shelf 13. During operation, the distance between the two bases 1 (i.e., the racking length) is first changed by adjusting the position of the telescopic section 3 within the main sleeve 2. The telescopic section 3 is movably connected inside the main sleeve 2, and its end is fixedly connected to another base 1; sliding the telescopic section 3 allows for continuous adjustment of the span. After adjusting to the required span, tighten the fastening pin 4 on the top surface of the main sleeve 2, so that the bottom end of the fastening pin 4 abuts against the end of the top surface of the telescopic section 3, thereby fixing the position of the telescopic section 3 and ensuring span stability. The upright 5 is fixed to the top of the base 1, and has multiple positioning holes 6 for installing the support frame 7. The support frame 7 is generally X-shaped, and its end has a long strip guide groove 8; by aligning the guide groove 8 with the positioning holes 6 on the upright 5, inserting the threaded pin 9, and threading the fastener 10 (such as a washer nut) on the outer surface of the threaded pin 9, the support frame 7 can be detachably fixed to the upright 5, providing lateral support. The shelf 13 is hung on the hanging holes 11 on the side of the upright 5 by hooks 12. The hanging holes 11 are in groups of three, allowing the shelf 13 to be flexibly adjusted in height and position. The length of the shelf 13 can be selected to match the size according to the adjusted spacing of the base 1 to ensure stable load-bearing. The entire rack, through span adjustment and modular assembly, adapts to the storage needs of different goods.

[0039] The working principle of this utility model is as follows:

[0040] First, place the two bases 1 on a flat surface, ensuring their stability. The sides of each base 1 are secured to the main sleeve 2 with screws. The main sleeve 2 is made of hollow stainless steel and possesses sufficient strength. Insert the telescopic section 3 into the main sleeve 2, initially fully inserted to minimize the gap between the two bases 1. The end of the telescopic section 3 is connected to the other base 1 with screws. The uprights 5 are welded to the top of the bases 1, and the positioning holes 6 on the uprights 5 are arranged in a linear array for even distribution of support points.

[0041] Due to warehouse space limitations, the shelf length needs to be adjusted to 2.2 meters. Loosen the fastening pin 4 on the top surface of the main sleeve 2, and then pull the telescopic section 3 outwards to gradually increase the distance between the two bases 1 to 2.2 meters. Observe the scale or use a measuring tool to ensure the distance is accurate. Tighten the fastening pin 4 so that the bottom end of the fastening pin 4 is tightly against the end of the top surface of the telescopic section 3 to prevent the telescopic section 3 from sliding and fix the span.

[0042] Based on the required height of the goods, install the support frame 7 on the column 5 at a height of 1 meter above the ground. Align the guide groove 8 of the support frame 7 with the positioning hole 6 at the corresponding height on the column 5, and insert the threaded pin 9 so that the threaded pin 9 passes through the guide groove 8 and the positioning hole 6.

[0043] Thread fasteners 10 onto the outer surface of threaded pin 9, and tighten fasteners 10 with a tool to ensure the support frame 7 is flush against the upright 5. The X-shaped design of the support frame 7 provides lateral stability, and the guide groove 8 allows for fine-tuning of the height. Select a shelf 13 with a length matching the adjusted span of 2.2 meters. The hooks 12 and shelf 13 are integrally molded from aluminum alloy, making them lightweight and durable. Hook the hooks 12 into a set of hook holes 11 on the side of the upright 5 (three hook holes 11 per set), ensuring the hooks 12 are securely attached. Place the shelf 13 flat on the hooks 12 to form a load-bearing platform. Repeat steps 3 and 4 to install the support frame 7 and shelf 13 at multiple heights to form a multi-level shelving unit.

[0044] The shelving is used to store boxed goods. If the span needs to be shortened to 1.8 meters later, simply loosen the fastening pin 4, push the telescopic section 3 into the main sleeve 2, adjust the span, tighten it again, and replace it with a 1.8-meter long shelf 13. The entire adjustment process does not require disassembling the main structure, making it simple and efficient.

[0045] Compared with the prior art, the present invention has the following advantages:

[0046] This adjustable-span storage rack features a sliding design between the main frame 2 and the telescopic section 3, allowing for continuous adjustment of the distance between the base 1 and the frame. This adapts to different warehouse spaces and varying product sizes, enhancing the rack's versatility and applicability. Users no longer need to purchase multiple fixed-size racks, saving costs. The rack is highly stable and secure: the fastening pin 4 mechanism ensures the telescopic section 3 remains securely fixed, preventing rack deformation; the X-shaped structure of the support frame 7 and the threaded pin 9 connection enhance overall rigidity and reduce swaying; the uprights 5 are firmly welded to the base 1, and the linear array of positioning holes 6 ensures even stress distribution and strong load-bearing capacity.
