[0019] Please refer to Figures 1-3 This utility model provides a decorative profile, including a first connecting plate 1, a second connecting plate 2, and a C-shaped aluminum profile 3; The C-shaped aluminum profile 3 includes a first vertical plate 31, a horizontal plate 32, and a second vertical plate 33; the first vertical plate 31 is disposed on one side of the horizontal plate 32, and the second vertical plate 33 is disposed on one side of the horizontal plate 32; the first vertical plate 31, the horizontal plate 32, and the second vertical plate 33 cooperate with each other to make the cross-section of the C-shaped aluminum profile 3 form a C shape; The horizontal plate 32 is provided with a fixing protrusion 34 on the side near the first vertical plate 31. The fixing protrusion 34 cooperates with the first vertical plate 31 to form a hook groove 311. The inner wall of the hook groove 311 away from the first vertical plate 31 is provided with a fixing side groove 312. One end of the first connecting plate 1 is provided with a hook part 11, which is engaged in the fixing side groove 312. The inner side of the second vertical plate 33 is provided with a snap-fit ​​groove 331, and one end of the second vertical plate 33 is provided with a snap-fit ​​protrusion 21, which snaps into the snap-fit ​​groove 331. The first connecting plate 1 and the second connecting plate 2 are respectively connected to the external base by bolts.

[0020] The decorative profile includes a first connecting plate 1, a second connecting plate 2, and a C-shaped aluminum profile 3. The first connecting plate 1 engages with the C-shaped aluminum profile 3 through a hook 11, and the second connecting plate 2 engages with the C-shaped aluminum profile 3 through a hook 311. Bolts are then used to connect the first connecting plate 1 and the second connecting plate 2 to the external substrate, forming a mutually cooperating connection structure. This improves the connection stability between the first connecting plate 1, the second connecting plate 2, and the C-shaped aluminum profile 3, as well as between the first connecting plate 1, the second connecting plate 2, and the external substrate. It does not have high requirements for the flatness and cleanliness of the substrate surface, and can effectively avoid loosening and falling off due to vibration, external force, and other factors during use, so that the decorative profile can maintain a stable installation state for a long time.

[0021] The C-shaped aluminum profile 3 is integrally formed from a first vertical plate 31, a horizontal plate 32, a second vertical plate 33, and a fixing protrusion 34. The first vertical plate 31 and the fixing protrusion 34 form a groove 311 for fixed connection with the first connecting plate 1. The first connecting plate 1 is fixedly connected to the C-shaped aluminum profile 3 by engaging with the groove 311 through a hook part 11. The second connecting plate 2 is fixedly connected to the C-shaped aluminum profile 3 by engaging with the engaging protrusion 21 through the engaging groove 331.

[0022] Specifically, the bottom of the snap-fit ​​groove 331 is provided with a fixing protrusion 332, and the snap-fit ​​protrusion 21 is provided with a groove that matches the shape of the fixing protrusion 332, and the fixing protrusion 332 is embedded in the groove.

[0023] By adopting the above structure, the fixed protrusion 332 is fixed by fitting the groove. On the basis of the engagement of the snap-fit ​​protrusion 21 and the snap-fit ​​groove 331, multiple fixed structures are added to form a double snap-fit ​​effect, which avoids loosening caused by external forces such as vibration and impact, and improves the stability of the connection between the second connecting plate 2 and the C-shaped aluminum profile 3.

[0024] Specifically, the fixed protrusion 332 is inclined toward one side of the horizontal plate 32.

[0025] In practical applications, the tilt angle of the fixed protrusion 332 is 45°. This structure restricts the relative displacement between the snap-fit ​​protrusion 21 and the snap-fit ​​groove 331 in a direction parallel to the bottom of the groove, further improving the stability of the connection between the second connecting plate 2 and the U-shaped aluminum profile 3.

[0026] Specifically, the first vertical plate 31 has a first protruding ridge 313 near its upper end, and the outer side of the first connecting plate 1 abuts against the first protruding ridge 313; the second vertical plate 33 has a second protruding ridge 333 near its upper end, and the outer side of the second connecting plate 2 abuts against the second protruding ridge 333.

[0027] With the above structure, the first protruding rib 313 provides lateral restraint to the first vertical plate, and together with the fixing structure of the hook part 11 and the hook groove 311, it further improves the stability of the connection between the first connecting plate 1 and the C-shaped aluminum profile 3. Meanwhile, the second protruding rib 333 provides lateral restraint to the second vertical plate 33, improving the connection stability between the second protruding rib 333 and the second vertical plate 33.

[0028] Furthermore, decorative mounting grooves 35 are provided on the outer side wall of the first vertical plate 31, the outer side wall of the second vertical plate 33, and both sides of the bottom of the horizontal plate 32.

[0029] The decorative mounting groove 35 provides a location for installing decorative components. The decorative mounting grooves 35 on the first vertical plate 31 and the second vertical plate 33 can be used to embed metal decorative strips to enhance the texture, while the mounting grooves on both sides of the bottom of the horizontal plate 32 can be used to install light strips for ambient lighting. This structure can meet the personalized decorative needs of different scenarios such as interior and exterior walls, ceilings, and baseboards, improving the decorative properties of the decorative profiles.

[0030] Furthermore, the decorative mounting groove 35 includes a trumpet-shaped channel portion 351, a transition connection portion 352, and an arc-shaped concave cavity portion 353. One end of the trumpet-shaped channel portion 351 forms the opening of the decorative mounting groove 355, and the other end of the trumpet-shaped channel portion 351 is connected to one end of the transition connection portion 352. The other end of the transition connection portion 352 is connected to the arc-shaped concave cavity portion 353. The inner diameter of the trumpet-shaped channel portion 351 gradually decreases along the direction from the opening of the decorative mounting groove 35 to the bottom of the groove. The inner diameter of the other end of the trumpet-shaped channel portion is smaller than the inner diameter of the opening of the arc-shaped concave cavity portion 353.

[0031] With the above structure, the inner diameter of the end of the trumpet-shaped channel portion 351 is smaller than the inner diameter of the opening of the arc-shaped concave cavity portion 353, so that the arc-shaped concave cavity portion 353 forms a structural difference of "narrow entrance and wide interior". When the protrusion of the decorative piece is inserted into the arc-shaped concave cavity portion 353 from the side of the decorative profile, it will be limited by the narrow opening formed by the trumpet-shaped channel portion 351 and the transition connection portion 352. Combined with the wrapping effect of the concave cavity portion, it can effectively prevent the decorative piece from falling outward due to vibration or external force pulling.

[0032] Specifically, the bottom of the horizontal plate 32 is provided with a wave-shaped decorative surface 36, the cross-section of which is wave-shaped; the wave-shaped decorative surface 36 is located between two decorative mounting grooves 35 at the bottom of the horizontal plate 32.

[0033] By adopting the above structure, the visual appeal of the decorative profile can be enhanced by adding a wave-shaped decorative surface 36, making the decorative profile more beautiful.

[0034] Specifically, the inner wall of the hook groove 311 near the first vertical plate 31 is provided with a first transition arc surface 314, and the outer side of the hook part 11 is provided with a second transition arc surface 111.

[0035] With the above structure, when the hook part 11 is inserted into the hook part 11 and hooks the fixed side groove 312, it is smoother, reducing friction, wear and noise, and reducing installation difficulty.

[0036] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without inventive effort, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
