Description

Technical Field

[0001] This utility model relates to the field of shelving technology, and in particular to a modular shelving unit with flush-mounted and detachable shelves. Background Technology

[0002] Modular shelving units are becoming increasingly popular due to their ease of transportation and storage. Furthermore, some modular furniture pieces are favored because they can be randomly combined into suitable shapes and sizes to meet different needs.

[0003] Currently, the storage rack products available on the market typically use a method where a concave annular groove is machined into the side wall of a circular upright tube. A plastic sleeve with a convex ring is fitted onto the annular groove of the upright tube, allowing the convex ring to fit and fix the groove. A conical iron ring is then passed through the circular upright tube to the outside of the sleeve, and is fixed to the circular upright tube together with the plastic sleeve using the taper. The metal wire mesh or partitions used for placing items are firmly and horizontally fixed to the conical iron ring to ensure load-bearing capacity.

[0004] However, in this type of shelving unit, where multiple shelves are arranged side-by-side, the plastic sleeves of adjacent shelves need to be staggered vertically on the uprights, making it impossible to fix them at the same height simultaneously. This results in misaligned and misaligned shelves, leading to untidy items and affecting aesthetics. Furthermore, adding or removing a shelf to change the layout requires completely removing the obstructing shelf from above or below, making assembly and modification cumbersome. Therefore, further improvements are needed. Utility Model Content

[0026] Example Reference Figures 1 to 5 The present invention proposes a modular shelving unit with flush-mountable and detachable shelves, comprising: several uprights 10, shelf assembly 20, and connecting support plates 30. The column 10 has a hollow rectangular tube structure, with several tube grooves 11 arranged vertically at intervals on the side walls on opposite sides; the inner opening of the connecting support plate 30 is provided so that it can be fitted onto the outer side of the column 10; the inner side of the connecting support plate 30 is provided with an inner connecting part 31, which can be inserted into the tube groove 11; the outer side of the connecting support plate 30 is a tapered surface that gradually expands from top to bottom; the connecting support plates 30 can be clamped at the same height on opposite sides of the column 10. The outer periphery of the shelf assembly 20 is provided with an open conical sleeve 21. The inner side of the open conical sleeve 21 is open and can be clamped to the outer side of the connecting support piece 30. The inner side of the open conical sleeve 21 is a conical surface that gradually narrows from top to bottom, which can fit tightly against the outer side of the connecting support piece 30.

[0027] This utility model addresses the core pain points of existing circular vertical tube shelving units, such as misaligned side-by-side shelves 23 and cumbersome assembly and disassembly. Through structural innovation, it achieves multiple technological breakthroughs, with the following specific benefits: 1. Flat and aesthetically pleasing shelves 23, flexible combination: The design of rectangular columns 10 and column grooves 11 of the same height allows the connecting support pieces 30 of adjacent shelves to be installed at the same height, completely solving the problem of misalignment of shelves 23 in traditional products. The items are placed neatly and uniformly, enhancing the decoration of the space; it supports multiple shelves to be freely arranged side by side and spliced ​​together to adapt to different space layout needs.

[0028] 2. Convenient and efficient assembly and disassembly, supporting flexible and independent assembly and disassembly of shelves 23: The snap-fit ​​connection between the connecting support plate 30 and the column 10, and the tight fit between the open conical sleeve 21 and the conical surface of the connecting support plate 30, allow for quick insertion and removal of shelf components 20 without tools. When adding or removing shelves 23, there is no need to remove the blocking shelves 23, simplifying the operation process and meeting the needs of immediate adjustment of the layout space; a certain shelf 23 can be added, removed or adjusted independently without removing other shelves 23, greatly improving the convenience of assembly changes and the flexibility of spatial layout.

[0029] 3. Stable and reliable with excellent load-bearing capacity: The tapered surfaces of the connecting support plate 30 and the open tapered sleeve 21 form a tight tapered fit. By utilizing the self-centering characteristics of the tapered surface contact and the advantage of large area force distribution, the load stress is dispersed, local stress concentration is avoided, and the structural stability and load-bearing capacity are significantly improved.

[0030] In this embodiment, the connecting support piece 30 includes a clamping body 32 and a clamping bending portion 33; the clamping body 32 can fit against the first sidewalls 12 on both sides of the column 10 in the lateral direction; the clamping bending portion 33 is disposed on the opposite sides of the clamping body 32 and can be sleeved on the second sidewalls 13 on both sides of the column 10 in the front-back direction; the width of the clamping bending portion 33 is less than or equal to half the width of the second sidewall 13. The width of the bent portion 33 of the clamping piece is less than or equal to half the width of the second side wall 13, so that the second side wall 13 in the front and rear directions of the column 10 can simultaneously accommodate the bent portions of the connecting support pieces 30 on both sides, avoiding spatial interference between adjacent support pieces during installation; the clamping piece body 32 fits against the first transverse side wall 12 of the column 10, and the bent portion fits over the front and rear second side walls 13, forming a "U"-shaped wrapping clamping structure, increasing the contact area between the connecting support piece 30 and the column 10, improving the clamping firmness, and preventing the support piece from shifting or rotating under force; this structural design makes the support piece more evenly stressed, further enhancing the stability of the shelf assembly 20; the segmented bending portion design not only ensures effective wrapping of the column 10, but also avoids material waste, making the connecting support piece 30 structure more compact and reducing processing costs; at the same time, it does not affect the hollow and lightweight characteristics of the column 10, balancing strength and portability.

[0031] In this embodiment, the connecting support piece 30 is made of plastic material, and the bent portion 33 of the clamping piece is elastic. The plastic material has good moldability and elasticity, and the elastic characteristics of the bent portion 33 of the clamping piece allow for slight deformation during installation, making it easy to fit into the column 10 and fit tightly; during disassembly, the elastic deformation allows for easy release from the column 10, avoiding the problems of jamming and damage during disassembly of traditional rigid clamping structures, and making the operation more labor-saving.

[0032] In this embodiment, at least two inner connecting portions 31 are vertically spaced along the inner side of the connecting support plate 30; at least two column grooves 11 are provided on the side wall of the column 10 at the same height area corresponding to the inner connecting portions 31. The at least two inner connecting portions 31 on the inner side of the connecting support plate 30 and the corresponding column grooves 11 at the same height area of ​​the column 10 form a multi-point engagement. Compared with a single-point connection, the stress points are more dispersed, avoiding loosening or damage caused by excessive local stress, and significantly improving the connection strength and fatigue resistance of the connecting support plate 30 and the column 10.

[0033] In some embodiments, please refer to Figures 1 to 3The inner connecting part 31 is a snap-fit ​​structure located inside the clamping body 32; the column groove 11 is a through-hole structure located on the first side wall 12, and the inner connecting part 31 can extend into and be snapped into the column groove 11. The design of the snap-fit ​​structure and the through-hole column groove 11 allows for simple installation: align the connecting support piece 30 with the first side wall 12 of the column 10, press to insert the snap-fit ​​structure into the through-hole, and secure it. This simple and direct operation requires no complex alignment or tool assistance, lowering the installation threshold. The through-hole column groove 11 has a simple processing technology, requires no complex cavity design, and does not affect the overall structural strength of the column 10. The through-hole structure facilitates observation of the snap-fit ​​status of the inner connecting part 31, allowing for quick confirmation of proper installation and improving assembly efficiency.

[0034] In some embodiments, please refer to Figure 4 and Figure 5 The inner connecting part 31 is a protruding column structure located inside the bending part 33 of the clamping piece; the column groove 11 is a limiting slide groove structure located on the second side wall 13 and extending to the first side wall 12; the inner connecting part 31 can slide into and be locked at the bottom of the column groove 11. The cooperation between the protruding column structure and the limiting slide groove allows the connecting support piece 30 to be installed by sliding, which is smoother than the pressing and locking method, and is especially suitable for space-constrained scenarios; during the sliding process, the slide groove can guide the protruding column to be accurately positioned, avoiding installation deviation. The limiting slide groove extends to the first side wall 12, forming a lateral wrapping around the protruding column, restricting the left and right swaying of the connecting support piece 30, and ensuring that the position of the support piece is fixed after installation; the contact area between the protruding column and the inner wall of the slide groove is large, the load is transmitted more evenly, local wear is reduced, and the service life is extended.

[0035] Specifically, the column mounting groove 11 has a "┐" shaped structure, including a connected horizontal sliding groove 111 and a vertical limiting groove 112; the vertical limiting groove 112 is vertically arranged on the second side wall 13; one side of the horizontal sliding groove 111 connects to the top of the vertical limiting groove 112, and the other side extends to the first side wall 12 and forms an opening; the inner connecting part 31 can slide into the opening of the horizontal sliding groove 111 and be locked at the bottom of the vertical limiting groove 112. After the convex column slides into the horizontal opening, it falls to the bottom along the vertical limiting groove 112, which not only restricts horizontal displacement but also prevents vertical detachment. The fixing effect is far superior to that of a single sliding groove design, ensuring that the shelf assembly 20 does not loosen during load-bearing and transportation.

[0036] In this embodiment, the shelf assembly 20 includes a support frame 22 and shelf panels 23; the shelf panels 23 are disposed on the support frame 22; and the connecting support pieces 30 are disposed on the outer periphery of the support frame 22. The shelf assembly 20 includes a support frame 22 and shelf panels 23. The support frame 22 provides a support structure, and the shelf panels 23 can be designed as fixed or detachable as needed, enhancing the flexibility of use and meeting different load-bearing and aesthetic requirements.

[0037] In some embodiments, the shelf 23 is a metal wire mesh frame structure welded integrally with the supporting frame 22; the metal wire mesh structure is ventilated and breathable, reduces dust accumulation, and is easy to clean, making it especially suitable for storing items that require ventilation (such as food and kitchen utensils).

[0038] In some embodiments, the shelf 23 is a detachable shelf placed on the support frame 22; the support frame 22 has an "L" shaped cross section and is provided with placement steps. The placement steps of the "L" shaped support frame 22 provide stable support for the shelf, effectively limiting the shelf from sliding or falling, and improving safety; the placement steps also allow for easy removal of the shelf for cleaning.

[0039] In this embodiment, the bottom of the column 10 is provided with a latch 14, which can be inserted from above and assembled with the top of another column 10. The latch 14 at the bottom of the column 10 allows the top of another column 10 to be inserted from above and downward, realizing the vertical assembly of the columns 10. This facilitates the expansion of the shelf height or the combination into a multi-layer structure, improves the modularity, and saves storage and transportation space.

[0040] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
