Description

Technical Field

[0001] This invention relates to the field of profile technology, and in particular to a multifunctional profile. Background Technology

[0002] In existing hanging systems, various functional profiles (such as main rail support beams, light tube mounting profiles, and clothes hanger crossbeams) are typically designed independently, resulting in a wide variety of profile types and specifications. This not only increases the cost of material procurement and warehousing management but also increases assembly complexity due to differences in the installation interfaces of different profiles. For example, traditional clothes hanger crossbeams often use a 48×48mm square column structure with a flat surface. When workers temporarily place clothes hangers, they are prone to slipping due to the lack of a fixed structure, affecting work efficiency. In addition, existing light tube profiles and main rail support beams require additional connectors for assembly, further increasing the number of parts and assembly steps. For example, the patent document "A Profile Frame, Profile Frame Connector and Profile Composite Frame" disclosed in Chinese patent literature, publication number "CN206205673U", describes a connector for connecting profile frames and a profile composite frame composed of profile frames and profile frame connectors. Matching hook structures are provided on the profile frames and profile frame connectors respectively. The two profile frames and the profile frame connectors provided between the two profile frames form the profile composite frame. The two profile frames are symmetrically arranged side-by-side at one end of the hook-shaped structure. The hook-shaped structures on the profile frames and the hook-shaped structures on the profile frame connectors are matched and connected. The joint end faces of the two profile frames are tightly fitted under the action of the profile frame connectors.

[0003] In traditional applications, when the clothes hanger beam uses a square column structure, the stability of the clothes hanger is insufficient, and it cannot share installation interfaces with the main rail or light tube profiles. The main rail support beam needs to be designed separately to accommodate the fixing of the main rail, but its function is singular and cannot be compatible with other components. Therefore, the hanging system still suffers from drawbacks such as high cost, inefficient management, and inconvenience in use. Therefore, there is an urgent need for a profile design solution that can integrate multiple functions, simplify the structure, and improve ease of use. Utility Model Content

[0004] To address the problem that current profiles have limited functionality and cannot be compatible with other components, this utility model provides a multifunctional profile that integrates multiple functions, simplifies the structure, and improves ease of use, achieving multifunctional integration such as main rail support, light tube installation, and clothes hanger hanging.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A multifunctional profile includes a main body with an arched cross-section. The arched structure has screw holes distributed along its length at its inner center. The two ends of the arched structure taper inwards to form two symmetrical flat openings. A supporting horizontal plate extending along the length is located in the middle of the arched structure, forming an assembly slot between the supporting horizontal plate and the two flat openings. This design, combining the arched structure, the symmetrical flat openings at both ends, and the supporting horizontal plate forming the assembly slot, with the arc-shaped guide screw holes distributed along the arched top, solves the problems of high cost and complex management caused by the need for independent design of multiple profiles in traditional hanging systems. This achieves multifunctional integration, self-alignment during installation, and uniform stress distribution, enabling individual load-bearing capacity for main rail support, light tube installation, and clothes hanger hanging.

[0007] Preferably, the profile body includes vertical sides extending on both sides of the arched structure, and the vertical sides smoothly transition with the arched structure.

[0008] Preferably, the inner surface of the flat opening is provided with anti-slip texture, which is a continuous groove parallel to the length direction of the profile.

[0009] Preferably, the interior of the arch structure is provided with reinforcing ribs extending along the length direction, and the reinforcing ribs connect the arch top and the supporting cross plate.

[0010] Preferably, the upper surface of the support plate is spaced apart from the screw holes, and the screw holes include two symmetrically arranged, outwardly arc-shaped and inwardly tapering hole walls.

[0011] Preferably, when the profile body is used as a main rail support beam, L-shaped connectors are installed at both ends of the main rail support beam. One end of the L-shaped connector is inserted and fixed in the assembly slot, and the other end is connected to the main rail.

[0012] Preferably, when the profile body is used as a lamp tube profile, an L-shaped connector is provided at the end of the lamp tube profile away from the lamp tube, and the L-shaped connector is inserted and fixed in the assembly slot.

[0013] Preferably, when the profile body is used as a clothes hanger beam, the arched structure, together with the two vertical sides, forms a U-shaped main rail support, on which clothes hanger components can be suspended.

[0014] Therefore, this utility model has the following beneficial effects.

[0015] The arched structure, combined with the flat opening and the supporting cross plate, forms a multi-functional assembly slot. By integrating the main rail support, light tube installation, and clothes hanger hanging functions with a single profile, the independent design requirements of multiple profiles in traditional hanging systems are reduced, thereby lowering material procurement and warehousing management costs.

[0016] The outer arc-shaped wall of the screw hole works in conjunction with the guide slope of the assembly slot to enable the screw to self-align and position, and the L-shaped connector to be quickly inserted, improving the installation efficiency of the main rail, lamp tube and external bracket, and avoiding assembly errors caused by manual adjustment.

[0017] The radial reinforcing ribs inside the arched structure combine with the continuous transition surface of the flat opening to transform the load into uniformly distributed compressive stress, thereby enhancing the bending stiffness of the profile and ensuring long-term stability when hanging clothes hangers or installing light tubes.

Detailed Implementation

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0027] Example 1

[0028] like Figure 1 , 2As shown, in this embodiment, a multifunctional profile is proposed. The main body 100 of the profile adopts an arched cross-section elongated structure. Screw holes 1 are distributed along the length direction from the center of the inner side of the arch apex. These screw holes 1 penetrate the entire length of the profile, and the hole walls 11 have symmetrical outward arc and inward curve geometric features. This allows the screw to achieve self-centering positioning through the arc-shaped guide of the hole walls 11 when screwed in, reducing installation offset. The two ends of the arched structure converge inward to form symmetrical flat openings 2. The ends of the flat openings 2 form a continuous transition surface with the arched sidewalls. This structure makes the stress distribution between the arch apex and the flat openings 2 more uniform when the profile is subjected to external loads, avoiding deformation caused by localized stress concentration. The arched structure has a support plate 3 extending along the length direction in the middle. The support plate 3 and the two flat openings 2 on both sides form an assembly slot 31. The opening width of the slot matches the thickness of the L-shaped connector 5. The inner wall of the slot and the lower surface of the support plate 3 form a vertical limiting surface to ensure that the L-shaped connector 5 does not deviate along the length direction of the profile after insertion.

[0029] The main body 100 of the profile extends vertical side surfaces 32 on both sides of the arched structure. The connection between the vertical side surfaces 32 and the arched structure is achieved through a smooth, rounded surface. The radius of curvature of this rounded surface matches the curvature of the arched structure, ensuring the continuity of the overall appearance of the profile and avoiding stress concentration caused by sharp corners. The outer surface of the vertical side surfaces 32 is parallel to the extension direction of the flat opening 2, forming a continuous planar support area. When the profile is used as a main rail support beam, this planar area can fit snugly against the external structure, enhancing installation stability. Reinforcing ribs are radially distributed along the length of the arched structure, connecting the arch top and the support cross plate 3. The cross-section of the reinforcing ribs is trapezoidal, with the top width smaller than the bottom width. The mechanical properties of the trapezoidal cross-section enhance the profile's bending resistance in the vertical direction.

[0030] like Figure 4 , 5 As shown, when the profile body 100 is used as a main rail support beam, the L-shaped connector 5 includes a first side 51 and a second side 52. The first side 51 of the L-shaped connector 5 is inserted into the inner wall of the mounting slot 31 and fixed with bolts. The second side 52 is installed on the side of the main rail 4 in the same way. This ensures that the L-shaped connector 5 and the main rail 4 are vertically connected.

[0031] During the assembly process of the profile body 100 as the main rail support beam, the first side 51 of the L-shaped connector 5 is first inserted into the assembly slot 31. The first side 51 contacts the lower surface of the support cross plate 3 until the entire side is fully inserted into the assembly slot 31. The first side 51 is then fixed with bolts. Subsequently, the second side 52 of the L-shaped connector 5 is fixed to the side of the main rail with bolts. Because the width of the assembly slot 31 matches the thickness of the L-shaped connector 5, and the vertical limiting surface of the slot's inner wall restricts horizontal displacement, the position of the L-shaped connector 5 along the profile's length is precisely controlled by the spacing of the screw holes. After the main rail is installed, its load is transferred to the arched structure of the profile through the L-shaped connector 5. The arched structure converts the vertical load into compressive stress along the arch top and sidewalls, and the stress is evenly diffused throughout the entire profile cross-section through the radial distribution of reinforcing ribs, avoiding localized overload.

[0032] During installation, the contact surface between the vertical side 32 and the external structure can be cushioned by adding rubber pads. The thickness of the rubber pads is adapted to the flatness of the vertical side 32, and the micro-protrusions on the surface of the pads are embedded in the anti-slip grooves on the profile surface to further prevent relative sliding after installation. The flat end 2 of the arched structure achieves rapid connection during profile splicing through a guide block and groove insertion structure. The cross-sectional shape of the guide block is consistent with the inner contour of the flat end 2, ensuring the continuity of the spliced ​​profile in the length direction.

[0033] Example 2

[0034] like Figure 6 , 7 As shown, in this embodiment, the profile body 100 serves as the connector of the lamp mounting frame 8. Its cross-section is arched, and screw holes 1, distributed along the length of the inner center of the arch, penetrate the entire length of the profile body 100. The hole walls 11 of the screw holes 1 have symmetrical outward arc and inward curvature, allowing the screws to achieve self-centering positioning through the guiding effect of the arc-shaped hole walls 11 when screwed in, avoiding installation misalignment. The two ends of the arched structure converge inward to form symmetrical flat openings 2. The ends of the flat openings 2 are connected to the arched sidewalls by a continuous transition surface. The curvature of the transition surface is consistent with the overall arc of the arched structure, ensuring that when the profile bears the suspension load of the lamp mounting frame 8, the stress is evenly transmitted to the flat openings 2 along the curved surface, reducing the risk of local stress concentration. The supporting horizontal plate 3 extends along the middle of the arched structure, and its width matches the transverse dimension of the arch. The upper surface of the supporting horizontal plate 3 forms a continuous planar area with the arch, which is used to support the mounting base of the lamp clip 7.

[0035] The profile body 100 is vertically installed at both ends of the top of the lamp tube mounting frame 8. The two profile bodies 100 are arranged in parallel, and the vertical side 32 of its arched structure is aligned with the side of the lamp tube mounting frame 8. The connection between the vertical side 32 and the arched structure is made by a smooth transition arc surface. The radius of curvature of the arc surface is consistent with the curvature of the arched structure, so that there is no sharp corner interference between the contact surface of the profile body 100 and the lamp tube mounting frame 8. The outer surface of the vertical side 32 is parallel to the extension direction of the flat opening 2, forming a continuous planar support area. This planar area fits against the side wall of the lamp tube mounting frame 8 during installation and is rigidly fixed by bolt preload. The reinforcing ribs arranged radially along the length of the arched structure are connected at the top to the inner side of the arch and at the bottom to the lower surface of the support plate 3, forming a triangular support structure. This structure can convert the suspension load of the lamp tube mounting frame 8 into tensile and compressive stress of the reinforcing ribs, thereby improving the bending stiffness of the profile.

[0036] The lamp holder 7 includes a rectangular plate and side plates 71 vertically arranged on both sides of the plate. The length direction of the plate is consistent with the length direction of the profile body 100. Two rows of through holes are provided on the back of the plate. The spacing of the through holes matches the distribution spacing of the dome screw holes 1. After the screw passes through the through holes, it is screwed into the screw hole 1 of the profile body 100. The outer arc-shaped hole wall 11 of the screw hole 1 provides radial constraint on the screw shank, preventing axial loosening. The height of the side plate 71 is adapted to the side wall thickness of the lamp mounting frame 8. The inner surface of the side plate 71 has an inwardly inclined guide slope extending from the bottom to the top of the plate, forming a gradually narrowing locking space. When the lamp mounting frame 8 is inserted into the lamp holder 7, its side wall slides into the locking space along the guide slope. The end of the side plate 71 has an inwardly bent limiting flange. The width of the flange matches the edge thickness of the side wall of the lamp mounting frame 8, limiting the vertical displacement of the lamp mounting frame 8.

[0037] The profile body 100 is connected to the top ceiling component via an L-shaped connector 5. The first side 51 of the L-shaped connector 5 is inserted into the mounting slot 31 of the arched structure. The mounting slot 31 is formed by the gap between the supporting horizontal plate 3 and the flat opening 2. The thickness of the first side 51 of the L-shaped connector 5 matches the width of the mounting slot 31. After the first side 51 is inserted, its end contacts the lower surface of the supporting horizontal plate 3. The thickness of the supporting horizontal plate 3 gradually increases from the arch to the flat opening 2, forming a variable cross-section structure. This design optimizes the profile weight while ensuring the load-bearing strength of the first side 51. The second side 52 of the L-shaped connector 5 has two rows of mounting holes. The spacing of the mounting holes is consistent with the distribution spacing of the ceiling joists 101. The profile body 100 is fixed to the ceiling joists with bolts to achieve the suspended installation of the profile body 100.

[0038] When assembling the lamp mounting frame 8 with the profile body 100, first align the through hole on the back of the lamp clip 7 with the screw hole 1 of the profile body 100, and screw in the screws to complete the initial fixing. Then, push the side wall of the lamp mounting frame 8 into the engaging space along the guide slope of the side plate 71 of the lamp clip 7 until the edge of the side wall contacts the limiting flange. At this time, the top end face of the lamp mounting frame 8 is in contact with the upper surface of the support horizontal plate 3 of the profile body 100, forming a surface contact support. The weight of the lamp mounting frame 8 is transferred to the arched structure through the support horizontal plate 3. The arched structure converts the vertical load into compressive stress along the arch top and the flat opening 2, and diffuses the stress to the entire profile cross section through the radial distribution of the reinforcing ribs. The anti-slip texture on the inner surface of the flat section 2 is composed of continuous grooves parallel to the length of the profile. The cross-section of the groove is trapezoidal. When it is necessary to temporarily adjust the position of the lamp tube mounting frame 8, the worker can manually apply force through the groove of the flat section 2. When the side wall of the trapezoidal groove comes into contact with the tool or finger, friction is generated to prevent slippage during operation.

[0039] The flat end of the arched structure 2 is equipped with a guide block and groove insertion structure. The cross-sectional shape of the guide block is consistent with the inner contour of the flat end 2. When two profile bodies 100 need to be extended and spliced, the guide block of one profile is inserted into the groove of the other profile. The outer surface of the guide block is tightly fitted with the inner wall of the groove, and the straightness after splicing is maintained by friction. The planar support area on the outer surface of the vertical side 32 is in contact with the contact surface of the ceiling joist during suspension installation. A rubber gasket is added between the contact surfaces. The thickness of the gasket is adapted to the processing tolerance of the planar support area. The micro-protrusion structure on the surface of the gasket is embedded in the anti-slip groove on the surface of the profile to prevent relative sliding after installation.

[0040] Under vibration conditions, the limiting flange of the lamp mounting frame 8 and the contact surface between the lamp clip 7 side plate 71 and the edge of the lamp mounting frame 8 side wall generate fretting friction, consuming vibration energy. Simultaneously, the radial constraint force of the screws and the rigid support of the lamp clip 7 plate form a composite fixing mechanism, preventing the lamp mounting frame 8 from loosening due to long-term vibration. The triangular support structure of the reinforcing ribs disperses the locally concentrated load to the side wall of the arched structure. The curved surface characteristics of the arched side wall further transform the load into uniformly distributed compressive stress, preventing plastic deformation of the profile.

[0041] During the assembly process of the profile body 100 as a connector for the lamp mounting frame 8, the first side 51 of the L-shaped connector 5 is first inserted into the assembly slot 31 until its end contacts the lower surface of the support plate 3. Then, the second side 52 of the L-shaped connector 5 is fixed to the ceiling joist with bolts. After the lamp clip 7 is fixed to the profile body 100 with screws, the lamp mounting frame 8 is pushed into the engagement space along the guide slope of the side plate 71 and locked in position by the limiting flange. The lamps inside the lamp mounting frame 8 are fixed by clips or clamps, and their weight is transferred to the support plate 3 of the profile body 100 through the side wall of the mounting frame, and finally supported by the arched structure and reinforcing ribs.

[0042] In this embodiment, the profile body 100 achieves rapid assembly and stable suspension of the lamp mounting frame 8 through the coordinated design of the arched structure, the supporting cross plate 3, and the lamp clip 7. The guide slope and limiting flange of the side plate 71 of the lamp clip 7 form a mechanical locking structure, which, combined with the radial constraint of the screws, ensures the positioning accuracy and vibration resistance of the mounting frame. The geometric features of the arched structure and the distribution of internal reinforcing ribs optimize the mechanical load-bearing characteristics of the profile, while the trapezoidal groove with anti-slip texture and the guide block insertion structure enhance the ease of operation and system expandability.

[0043] Example 3

[0044] like Figure 3 As shown, in this embodiment, the profile body 100 is designed to meet the hanging requirements of the clothes hanger assembly 102 through a combination of an arched structure and vertical side 32. The screw holes 1, distributed along the length of the inner center of the arched top, have symmetrical outward-curving and inward-receding geometric features on their walls 11. This allows the profile body 100 to be fixed to the external bracket 8 via these screw holes 1 when installed as a clothes hanger beam. The arc-shaped guiding effect of the hole wall 11 during screw insertion from the external bracket 8 ensures that the screw axis is perpendicular to the length of the profile, avoiding uneven load distribution caused by installation tilt. The two ends of the arched structure converge inward to form symmetrical flat openings 2. The ends of the flat openings 2 are connected to the arched sidewalls via a continuous transition surface. The curvature of the transition surface is consistent with the overall arc of the arched structure, allowing the hanging load of the clothes hanger to be evenly transferred to the flat openings 2 along the curved surface, reducing local stress concentration. The support plate 3 extends along the middle of the arch structure, and its width matches the lateral dimension of the arch. The upper surface of the support plate 3 forms a continuous planar area with the arch. This area is used as an auxiliary support surface in the clothes hanger hanging scenario for temporary placement of tools or accessories.

[0045] When the profile body 100 is used as a hanger beam, the arched structure and the two vertical side panels 32 together form the U-shaped main rail support 6. The outer surface of the vertical side panel 32 is parallel to the extension direction of the flat opening 2, forming the vertical sidewall of the U-shaped structure, and the top of the arched structure serves as the bottom bearing surface of the U-shaped structure. The opening of the U-shaped structure faces upward, and the height of its internal space is adapted to the bending radius of a standard hanger hook. The bent end of the hanger hook is embedded in the U-shaped structure, and the straight section of the hook extends along the outer surface of the vertical side panel 32, limiting the horizontal displacement of the hanger assembly through the sidewall of the U-shaped structure. In this embodiment, the hanger assembly is rolled on the U-shaped main rail support 6 by rollers.

[0046] The reinforcing ribs inside the arched structure are radially distributed along its length. At the junction connecting the arch top and the supporting horizontal plate 3, the cross-section of the reinforcing ribs is trapezoidal, with its top width smaller than its bottom width. When the hanging load of the clothes hanger acts on the bottom bearing surface of the U-shaped structure, the load is transferred to the reinforcing ribs through the arch top. The trapezoidal cross-section of the reinforcing ribs disperses the stress to the supporting horizontal plate 3 and the flat opening 2 through the expansion of its bottom width, avoiding local deformation of the arch top due to concentrated load. The connection between the vertical side 32 and the arched structure is made by a smooth transition arc surface. The radius of curvature of the arc surface is consistent with the curvature of the arched structure. This design allows the stress of the sidewall of the U-shaped structure to be evenly diffused along the arc surface to the entire profile cross-section when subjected to the lateral tensile force of the clothes hanger, preventing cracks from forming at the corners.

[0047] During the assembly process of the main body 100 of the profile as the crossbeam of the clothes hanger, it is fixed to the external bracket 8 through the screw hole 1 of the arch. The screw passes through the through hole of the bracket 8 and is screwed into the screw hole 1. The outer arc-shaped hole wall 11 of the screw hole 1 provides radial constraint on the screw shank, preventing the screw from loosening axially due to the shaking of the clothes hanger. The vertical side wall of the U-shaped structure is in contact with the mounting surface of the external bracket 8. A rubber gasket is added between the contact surfaces. The thickness of the gasket is adapted to the flatness of the side wall. The micro-protrusion structure on the surface of the gasket is embedded in the anti-slip groove on the surface of the profile, further preventing relative sliding after assembly. When the curved end of the clothes hanger hook is embedded in the U-shaped structure, the straight section of the hook contacts the outer surface of the vertical side 32. The planar area of ​​the vertical side 32 provides stable guiding support for the hook, preventing the clothes hanger from falling off due to external force.

[0048] In this embodiment, the profile body 100 achieves stability and convenience in hanging the clothes hanger through the structural features of the U-shaped main rail support 6. The geometric fit between the arched structure and the vertical side 32 optimizes the load distribution of the clothes hanger, while the trapezoidal grooves of the anti-slip texture and the radial distribution of the reinforcing ribs further enhance the resistance to deformation.
