Description

Technical Field

[0001] This utility model relates to the field of exhibition display racks, and in particular to a prefabricated display rack. Background Technology

[0002] Display racks, widely used in exhibitions, retail, and advertising, directly impact display effectiveness and user experience through their design and functionality. With the diversification of display needs, display racks require rapid setup, adjustment, and adaptation to various display content in different scenarios. However, existing display rack technologies have some shortcomings in terms of structural design and operational flexibility.

[0003] In existing technologies, common display racks typically employ fixed or welded structures. For example, some display racks are formed into a fixed shape by welding metal frames. While this provides a degree of stability, the structure is not detachable and difficult to adjust to the size or shape of the display space, thus limiting its usability. Furthermore, these fixed display racks occupy a significant amount of space during transportation and storage, making them inconvenient to carry and reuse, increasing operating costs. Another common display rack design uses a simple splicing structure, such as connecting metal rods into a frame with bolts. While this design offers some detachability, its assembly process is complex, requiring various tools, and the connectors have poor versatility. When display needs change, such as requiring changes to the size of the display panels or adjustments to the display angle, existing display racks often struggle to adapt quickly, resulting in cumbersome adjustments and impacting display efficiency.

[0004] In summary, existing display rack technologies suffer from shortcomings in terms of assemblability and flexibility of use, making it difficult to meet the demands of modern display scenarios for rapid assembly and flexible adjustment. Therefore, there is an urgent need for a display rack structure that can overcome these deficiencies to improve display efficiency and user experience. Utility Model Content

[0031] Example 1

[0032] Please see Figures 1 to 5 This invention provides an assembly-type display rack 10, which comprises a base frame 11, a vertical support assembly 20, a display panel fixing assembly 30, a cable support assembly 40, and a top cover assembly; wherein,

[0033] The base frame 11 forms the foundation of the prefabricated display rack 10, consisting of two horizontal aluminum profiles 12 connected in an L-shape. This L-shaped design allows the prefabricated display rack 10 to flexibly adapt to corner spaces or be placed against a wall, optimizing the space utilization of the exhibition area. The horizontal aluminum profiles 12 can be made of high-strength aluminum alloy, which is lightweight, corrosion-resistant, and aesthetically pleasing. In practice, the two horizontal aluminum profiles 12 are fixed by L-shaped embedded snap-fit ​​connectors, which are embedded in the T-grooves of the profiles and secured with screws. The vertical support assembly 20 provides height and structural rigidity for the prefabricated display rack 10, comprising three vertical aluminum profile columns 21. These three columns are fixed to the two sections of the horizontal aluminum profiles 12 of the base frame 11 at right angles, forming a corner support structure. The vertical aluminum profile columns 21 use the same aluminum alloy material as the base frame 11, and their cross-sectional design is compatible with the profiles of the base frame 11. In practice, the vertical aluminum profile columns 21 are fixed to the base frame 11 via right-angle connectors 14. The right-angle connectors 14 are embedded in the profile grooves and secured with bolts to form a rigid connection. The arrangement of the three vertical aluminum profile columns 21 enhances the overall stability of the prefabricated display rack 10, making it particularly suitable for supporting large display panels 35 or multi-sided display layouts.

[0034] The display panel fixing assembly 30, used to support and fix the display panel 35, consists of several circular optical axis rods 31 and D-type locking parts 33. The circular optical axis rods 31 are made of stainless steel, with a polished surface, making them corrosion-resistant and easy to clean. The circular optical axis rods 31 are arranged vertically and horizontally, respectively fixed to the vertical aluminum profile column 21 and the base frame 11, forming a rectangular frame structure to support the display panel 35. The horizontal circular optical axis rods 31 are fixed to the vertical circular optical axis rods 31 by cross-shaped optical axis connecting locks 37. The cross-shaped optical axis connecting locks 37 have mutually perpendicular through holes to accommodate and fix two circular optical axis rods 31, and are simultaneously fixed to the horizontal aluminum profile 12 of the base frame 11 by side screws, ensuring a secure connection between the frame and the base frame 11 via the overall cross-shaped optical axis connecting locks 37. The D-type locking element 33, as a form of locking element 32, is pivotally mounted on the horizontal circular optical shaft rod 31. Its pressing end can rotatably clamp the display plate 35, fixing the display plate 35 within the frame. The horizontal circular optical shaft rod 31 is also provided with an annular limiting ring 36, which can be fixed by a set screw to limit the position of the D-type locking element 33 and the display plate 35 and prevent slippage.

[0035] The cable support assembly 40, used to enhance the stability of the prefabricated display rack 10, includes a triangular connecting plate 41 and a steel cable 42.

[0036] The top cover assembly is located at the top of the vertical aluminum profile column 21 and is used to connect to and seal the vertical aluminum profile column 21. T-shaped top cover pieces are installed at the top of adjacent vertical aluminum profile columns 21, or they can span two vertical aluminum profile columns 21, connecting, fixing, and sealing the top opening to prevent dust from entering and improve the aesthetic appearance. The top of a single vertical aluminum profile column 21 is sealed with a square cover plate, made of the same material as the T-shaped top cover piece, typically aluminum alloy or plastic, with the same surface treatment as the vertical aluminum profile column 21.

[0037] During assembly, firstly, two horizontal aluminum profiles 12 are fixed using L-shaped embedded snap-fit ​​connectors to form an L-shaped base frame 11. Three vertical aluminum profile columns 21 are fixed to the two ends of the base frame 11, using right-angle connectors 14 to ensure a right-angle arrangement. Next, the display panel fixing assembly 30 is installed, fixing the vertical circular optical axis rod 31 to the vertical aluminum profile column 21. The horizontal circular optical axis rod 31 is connected to the vertical circular optical axis rod 31 and the base frame 11 via a cross-shaped optical axis connecting lock 37, forming the display panel 35 frame. D-shaped locking parts 33 and annular limiting rings 36 are installed on the horizontal circular optical axis rod 31 to fix the display panel 35. The triangular connecting plate 41 of the cable support assembly 40 is fixed to the vertical aluminum profile column 21, and the steel cable 42 is connected and tensioned via turnbuckles 43. Finally, the top cover assembly is installed, completing the assembly of the prefabricated display rack 10. Using standardized aluminum profiles and connectors 34, assembly and disassembly are simple. The inclined design of the cable support assembly 40 enhances structural rigidity through prestressing, solving the safety hazard of traditional display racks swaying under high loads or heights. The L-shaped base frame 11 and corner vertical support assembly 20 support multi-faceted or circular display layouts, optimizing space utilization and meeting complex exhibition needs.

[0038] Example 2

[0039] Based on Example 1, this embodiment further optimizes the structure of the assembled display rack 10, highlighting the application of right-angle connectors 14, D-type locking components 33, annular limiting rings 36, turnbuckles 43, and spring nuts to improve the stability, flexibility, and practicality of the structure.

[0040] The base frame 11 consists of two horizontal aluminum profiles 12 connected in an L-shape, suitable for corner or wall placement, optimizing space utilization. The two horizontal aluminum profiles 12 are secured by L-shaped embedded snap-fit ​​connectors, which are embedded in the T-slots of the profiles and tightened with screws to ensure a firm and seamless connection. A square cover plate is installed on the outside of the connection point to conceal the bolts and slots, improving the overall neatness of the appearance.

[0041] The vertical support assembly 20 includes three vertical aluminum profile columns 21, which are fixed to two sections of the base frame 11 at right angles to form a corner support structure. The vertical aluminum profile columns 21 are made of the same aluminum alloy as the base frame 11, and their cross-sectional designs are compatible to ensure structural consistency.

[0042] The vertical aluminum profile column 21 and the horizontal aluminum profile 12 are fixedly connected by right-angle connectors 14. The right-angle connectors 14 are L-shaped aluminum alloy parts, respectively embedded in the T-slots of the vertical aluminum profile column 21 and the base frame 11 profiles, and fastened with M6 bolts. This connection method ensures the precision and rigidity of the 90° turn, facilitates quick assembly and disassembly, and enhances the stability of the assembled display rack 10 under high loads. A square cover plate is installed on the outside of the connection point to cover the bolt heads and improve aesthetics.

[0043] The display panel fixing assembly 30, used to support and fix the display panel 35, consists of several circular optical axis rods 31 and locking members 32. The circular optical axis rods 31 are made of stainless steel, with a polished surface, are corrosion-resistant and easy to clean, and are arranged vertically and horizontally to form a rectangular frame. The horizontal circular optical axis rods 31 are connected to the vertical circular optical axis rods 31 and the base frame 11 via cross-shaped optical axis connecting locks 37. The cross-shaped optical axis connecting locks 37 have vertical through holes, and the rods are fixed by locking screws and secured to the base frame 11 by side screws. The locking members 32 are D-type locking members 33, pivotally mounted on the horizontally arranged circular optical axis rods 31, and have a clamping end for clamping the display panel 35. The D-type locking element 33, shaped like the letter "D," includes a hinge and a clamping end. During installation, it can be rotated open around the hinge. After placing the display panel 35 between the circular optical axis rod 31 and the locking element 32, it can be rotated closed, causing the clamping end to hold the surface of the display panel 35. This design facilitates quick installation and replacement of the display panel 35, adapting to display panels 35 of different sizes and materials (such as foam board and acrylic board), improving operational convenience and flexibility. A ring-shaped limiting ring 36 is provided on the horizontally arranged circular optical axis rod 31, connected to the rod 31, to limit the position of the D-type locking element 33. The ring-shaped limiting ring 36 is typically installed close to the edge of the display panel 35 or the locking element 32, preventing the locking element 32 or the display panel 35 from sliding on the circular optical axis rod 31, ensuring the display panel 35 remains in the predetermined position. This limiting design enhances the stability of the display panel 35, avoiding untidy displays or safety hazards caused by movement.

[0044] The cable support assembly 40, used to enhance the stability of the prefabricated display rack 10, includes a triangular connecting plate 41 and steel cables 42. The triangular connecting plate 41 is a metal plate with holes for connecting the steel cables 42, which are made of multiple strands of galvanized steel wire and are diagonally stretched between adjacent vertical aluminum profile columns 21. The steel cables 42 are connected to the triangular connecting plate 41 by turnbuckles 43, which are used to adjust the tension of the steel cables 42. The turnbuckles 43 are adjustment devices with knobs; rotation allows for precise control of the tension of the steel cables 42, forming prestressed support. This design allows the cable support assembly 40 to adjust the support strength according to the height, load, or environmental conditions of the prefabricated display rack 10, significantly improving the rigidity and stability of the structure in the vertical plane, making it particularly suitable for large display panels 35 or high wind load scenarios.

[0045] The triangular connecting plate 41 is fixed in the groove of the vertical aluminum profile column 21 by a spring-loaded nut, and its position can be adjusted along the height of the vertical aluminum profile column 21. The spring-loaded nut is a T-shaped nut with an elastic clip, which is inserted into the longitudinal groove of the vertical aluminum profile column 21 and clamped in place. This installation method facilitates adjustment of the height of the triangular connecting plate 41, thereby changing the angle of the steel cable 42 and the support effect to adapt to different display needs.

[0046] A top cover assembly is installed at the top of the vertical aluminum profile column 21 to connect to and seal the vertical aluminum profile column 21. T-shaped top cover pieces are installed at the top of adjacent vertical aluminum profile columns 21, spanning two columns, connecting, fixing, and sealing the top opening to prevent dust from entering and improve aesthetics. A square cover plate, made of aluminum alloy or plastic, is used to seal the top of each individual vertical aluminum profile column 21, with the same surface treatment as the vertical aluminum profile column 21.

[0047] During assembly, first, two horizontal aluminum profiles 12 are fixed using L-shaped embedded snap-fit ​​connectors to form an L-shaped base frame 11, and then a square cover plate is installed. Three vertical aluminum profile columns 21 are fixed to the base frame 11 using right-angle connectors 14, forming a corner vertical support assembly 20. The vertical circular optical axis rod 31 of the display panel fixing assembly 30 is fixed to the vertical aluminum profile column 21. The horizontal circular optical axis rod 31 is connected to the vertical circular optical axis rod 31 and the base frame 11 via a cross-shaped optical axis connecting lock 37. A D-shaped locking piece 33 and an annular limiting ring 36 are installed on the horizontal circular optical axis rod 31 to fix the display panel 35. The triangular connecting plate 41 of the cable support assembly 40 is fixed to the vertical aluminum profile column 21 using a spring nut, and the steel cable 42 is connected and tensioned using a turnbuckle 43. Finally, the top cover assembly is installed to complete the assembly.

[0048] Right-angle connector 14 ensures a rigid connection between the vertical aluminum profile column 21 and the base frame 11. Cable support assembly 40 uses turnbuckles 43 and spring nuts to achieve adjustable prestress, significantly enhancing structural stability and overcoming the tendency of traditional display racks to sway under high loads. D-type locking parts 33 and annular limiting rings 36 facilitate quick installation and adjustment of display panels 35, adapting to different sizes and materials and improving usability. Standardized connectors 34 and adjustable components support rapid assembly and disassembly, adapting to various display scenarios such as corner or multi-segment layouts. A square cover and top cover assembly conceal connector 34, resulting in a clean overall appearance suitable for high-end exhibition environments.

The base frame 11 also includes supporting aluminum profiles 13 that are snapped onto both sides of the horizontal aluminum profiles 12. These supporting aluminum profiles 13 are fixed to the side grooves of the horizontal aluminum profiles 12 by snaps or screws, increasing the lateral support of the base frame 11 and significantly enhancing its stability. This design is particularly suitable for large prefabricated display racks 10 or those bearing heavy display panels 35, preventing the base frame 11 from deforming or tilting due to excessive load and improving the overall structural load-bearing capacity.

[0052] The vertical support assembly 20 provides height and structural rigidity for the prefabricated display rack 10. It includes three vertical aluminum profile columns 21, each fixed to one end of the base frame 11 at right angles to form a corner support structure. The vertical aluminum profile columns 21 are made of the same aluminum alloy as the base frame 11, and their cross-sectional design is compatible with the base frame 11 profile, ensuring structural consistency and material uniformity. The vertical aluminum profile columns 21 are fixed to the base frame 11 via right-angle connectors 14. The right-angle connectors 14 are L-shaped aluminum alloy pieces, embedded in the T-slots of the vertical aluminum profile columns 21 and the base frame 11 profiles, and are secured with M6 bolts to form a rigid connection.

[0053] The display panel fixing assembly 30, used to support and fix the display panel 35, consists of several circular optical axis rods 31 and locking components 32.

The cross-shaped optical axis connecting lock 37 is a metal block with mutually perpendicular through holes, accommodating the vertical and horizontal circular optical axis rods 31 respectively. The rods are fixed by locking screws, ensuring the rigidity and stability of the frame and demonstrating the fixed connection of the cross-shaped optical axis connecting lock 37. The cross-shaped optical axis connecting lock 37 is also fixed to the horizontal aluminum profile 12 of the base frame 11 by side screws, reliably connecting the display panel 35 frame to the main structure of the assembled display rack 10. This design facilitates quick assembly and adjustment, while enhancing the load-bearing capacity of the display panel 35 frame.

[0054] The locking component 32 is a D-type locking component 33, pivotally mounted on a horizontally arranged circular optical axis rod 31, and has a clamping end for holding the display panel 35. The D-type locking component 33 is shaped like the letter "D," including a hinge and a clamping end. It can be rotated open around the hinge. After placing the display panel 35 between the circular optical axis rod 31 and the locking component 32, it can be rotated closed, so that the clamping end clamps the surface of the display panel 35, ensuring the display panel 35 is stably fixed. The horizontal circular optical axis rod 31 is also provided with an annular limiting ring 36, which is fixed by a set screw to limit the position of the D-type locking component 33 and the display panel 35, preventing slippage and ensuring a neat display effect. The display panel fixing assembly 30 consists of two sets, respectively located on both sides of the cable support assembly 40.
