Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, and in particular to a shelf with a flexible material that is easy to disassemble. Background Technology

[0002] A storage rack is a shelf made of materials such as metal, primarily used for storing, displaying, or organizing various items. Due to its advantages such as sturdy structure, high load-bearing capacity, and durability, metal storage racks are widely used in many fields.

[0003] However, most existing metal shelves require users to assemble them themselves, which is cumbersome, time-consuming, and labor-intensive, causing many inconveniences for users. When it is necessary to adjust the height of a shelf or to disassemble it partially, it is often necessary to remove all the upper or surrounding shelves and related connecting structures first. This disassembly and assembly method is not only complicated and inefficient, but also prone to problems such as stripped screws and loose connectors during frequent disassembly and assembly, resulting in a decrease in the connection strength of fasteners and thus affecting the stability and safety of the overall structure. Utility Model Content

[0004] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a shelf with a flexible material and an easy-to-disassemble device to solve the problem of complicated disassembly and assembly of shelves in the prior art.

[0005] To achieve the above and other related objectives, this utility model provides the following technical solution: a shelf with a flexible, easily detachable device, comprising: feet disposed at the bottom of the shelf; a first support rod disposed on the side of the shelf; a second support rod movably screwed onto the first support rod for adjusting the height of the shelf; a shelf disposed on the first and second support rods; a flexible washer snapped onto the first and second support rods, with a fastener on its outer ring; a fastener fitted onto the flexible washer; a recessed block is provided on the fastener, and a chamfered plate on the shelf snaps onto the recessed block.

[0006] The above technical solution achieves its purpose by incorporating a swivelable and adjustable structure on the support rod, combined with the snap-fit ​​mechanism of flexible washers and fasteners. This allows the shelves to be quickly installed and positioned by directly snapping their chamfered plates into the recesses on the fasteners, eliminating the need for traditional fastening methods such as bolts and nuts. This significantly simplifies the assembly and disassembly process. When it is necessary to adjust or remove a shelf, only manual force is required to cause the flexible washers and fasteners to deform elastically, allowing the shelf to be easily removed or repositioned without dismantling the upper and lower layers. This convenient and efficient operation ensures the shelf's overall structure is easy to assemble and disassemble, adjustable, and reliable for long-term use.

[0007] In one embodiment of this utility model, the fastener is a semi-circular ring with an opening in the middle and a symmetrical structure; the upper part of the fastener is a fastening outlet and the lower part is a fastening inlet; the diameter of the fastening outlet is smaller than the diameter of the fastening inlet.

[0008] To achieve the above technical solution, the fastener adopts a semi-circular symmetrical structure with an opening in the middle to facilitate elastic deformation and micro-adjustment during installation. The diameter of the fastening outlet is smaller than that of the fastening inlet, forming a tapered guide structure. In order to form an interference fit when fitted onto the flexible washer, the fastener's own elastic deformation generates a pre-tightening force at the fastening outlet during assembly, thereby tightly clamping it to the outer circumference of the flexible washer and effectively preventing loosening or detachment. This interference fit structure not only enhances the connection stability between the fastener and the flexible washer.

[0009] In one embodiment of this utility model, the fastening outlet is interference-fitted with the flexible washer, and the fastening inlet is clearance-fitted with the flexible washer.

[0010] To achieve the above technical solution, the fastening outlet and the flexible washer are fitted with an interference fit, and the elastic deformation of the fastener achieves tight compression, forming a pre-tightening force to prevent loosening or falling off, and ensuring the stability of the connection; while the fastening inlet and the flexible washer are fitted with a clearance fit, which facilitates the fastener to be smoothly inserted and slidably positioned along the axial direction of the flexible washer during installation, reducing assembly resistance.

[0011] In one embodiment of the present invention, the recess is located near the fastening inlet; the fastener further includes a bending member located on both sides of the opening of the fastener.

[0012] To achieve the above technical solution, the fastener has bending elements on both sides of the opening. These bending elements bend outward to form a reinforcing structure, which not only improves the structural strength of the fastener itself, but also serves as a force-applying handle during assembly, making it easy to manually open the fastener to complete the installation or disassembly operation, further improving the reliability of the connection and the ease of use.

[0013] In one embodiment of this utility model, the thickness of the fastener is at least 4 mm.

[0014] The above technical solution effectively improves the overall structural strength and deformation resistance of the fastener, enabling it to maintain good rigidity even when subjected to shelf loads and frequent disassembly and assembly.

[0015] In one embodiment of the present invention, the inner wall of the first support rod is provided with threads, and the outer wall of the second support rod is provided with a spiral mounting groove, wherein the threads and the mounting groove are screwed together.

[0016] To achieve the above technical solution, the second support rod can be rotated and raised along the first support rod by screwing the thread into the mounting groove, thereby adjusting the height of the shelf.

[0017] In one embodiment of this utility model, multiple sets of slots are evenly arranged on the first support rod, and numbers are marked between the slots and the mounting slots.

[0018] To achieve the above technical solution, corresponding numbers are marked between the card slot and the mounting slot on the outer wall of the second support rod. The card slot and the mounting slot are precisely aligned during the screwing process through the numerical markings, so that users can intuitively and quickly confirm the shelf installation position when adjusting the height of the shelf, ensuring that the height of each shelf is consistent and that the left and right sides are adjusted synchronously.

[0019] In one embodiment of the present invention, the flexible washer includes a first flexible component and a second flexible component; the first flexible component is sleeved on a first support rod; and the second flexible component is sleeved on a second support rod.

[0020] To achieve the above technical solution, the two components form a continuous support surface at the connection point, ensuring uniform stress on the shelf, reducing stress concentration, improving the stability and durability of the overall connection, and effectively buffering impacts during frequent height adjustments or disassembly / reassembly.

[0021] In one embodiment of the present invention, the first flexible component is divided into a first snap-fit ​​component and a second snap-fit ​​component, and the first snap-fit ​​component and the second snap-fit ​​component are connected in a cooperative manner; a first protruding component is provided on the inner wall of the first flexible component; the first protruding component is engaged with a slot.

[0022] The above technical solution is achieved by using a matching connection method and detachably assembling it onto the first support rod, which facilitates installation and replacement; the first protruding component cooperates with and engages with the slot, and the mechanical engagement between the first protruding component and the slot enables precise axial positioning of the flexible component. Combined with the elastic properties of the flexible material, it ensures a firm engagement and allows for repeated disassembly and assembly, thereby improving the stability of the structure.

[0023] In one embodiment of the present invention, the second flexible component is divided into a third snap-fit ​​component and a fourth snap-fit ​​component, and the third snap-fit ​​component and the fourth snap-fit ​​component are connected to each other; a second protruding component is provided on the inner wall of the second flexible component; the second protruding component is engaged with the mounting groove.

[0024] The above technical solution is achieved by using a matching connection method and detachably assembling it onto the second support rod, which facilitates installation and replacement; the second protruding component cooperates with and snaps into the mounting groove, and the mechanical engagement between the second protruding component and the mounting groove enables precise axial positioning of the flexible component. Combined with the elastic properties of the flexible material, it ensures a firm snap-fit ​​and allows for repeated disassembly and assembly, thereby improving the stability of the structure.

[0025] As described above, the flexible, easily detachable shelf of this utility model has the following advantages: By setting a swivelable and adjustable structure on the support rod and combining the snap-fit ​​of the flexible washer and the fastener, the shelf can be quickly installed and positioned by directly snapping its corner plate into the recess on the fastener, eliminating the need for traditional fastening methods such as bolts and nuts, thus significantly simplifying the assembly and disassembly process; when it is necessary to adjust or remove a shelf, only manual force is required to cause the flexible washer and the fastener to deform elastically, and the shelf can be easily removed or repositioned without disassembling the upper and lower layers, making the operation convenient and efficient; at the same time, the introduction of flexible material effectively alleviates the mechanical damage to the connecting structure caused by frequent disassembly and assembly, improves the stability and durability of the connection, and thus achieves the reliability of easy disassembly and assembly of the overall shelf structure.

[0033] By setting a swivelable and adjustable structure on the support rod, and combining the flexible washer 5 with the snap-fit ​​of the fastener 6, the shelf 4 can be quickly installed and positioned by directly snapping its chamfered plate 403 into the recess 603 on the fastener 6, eliminating the need for traditional fastening methods such as bolts and nuts, thus significantly simplifying the assembly and disassembly process. When it is necessary to adjust or remove a shelf 4, only manual force is required to cause the flexible washer 5 and the fastener 6 to elastically deform, and the shelf 4 can be easily removed or repositioned without dismantling the upper and lower layers. This makes the operation convenient and efficient, thus achieving easy disassembly and assembly, adjustability, and long-term reliability of the overall structure of the shelving unit.

[0034] Furthermore, multiple sets of reinforcing rods 401 are provided on the shelf 4, and reinforcing corrugated rods 402 are provided on the side. The four corners of the shelf 4 are cut off to form chamfered plates 403 on the side.

[0035] Furthermore, the inner wall of the first support rod 2 is provided with threads, and the outer wall of the second support rod 3 is provided with a spiral mounting groove 301, with the threads corresponding to the mounting groove 301.

[0036] The second support rod 3 can be rotated and raised along the first support rod 2 by screwing the thread into the mounting groove 301, thereby adjusting the height of the shelf.

[0037] Furthermore, multiple sets of slots 201 are evenly arranged on the first support rod 2, and numbers are marked between the slots 201 and the mounting slots 301.

[0038] The slot 201 and the mounting groove 301 on the outer wall of the second support rod 3 are both marked with corresponding numbers. The numerical markings enable the slot 201 and the mounting groove 301 to be precisely aligned during the screwing process, allowing users to intuitively and quickly confirm the installation position of the shelf 4 when adjusting the height of the shelf, ensuring that the height of each shelf is consistent and that the left and right sides are adjusted synchronously.
