[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0027] See Figure 1A preferred embodiment of a detachable casement window decorative trim assembly is provided. In this embodiment, the casement window decorative trim assembly is formed at the mullion position of the casement window, and it presents a simple structural form, including a mullion profile 1, a detachable fastener 2, and a decorative trim 5. In another embodiment, the corresponding mullion profile 1 can also be replaced by a window frame profile to adapt to the needs of different window types. The mullion profile 1 and the window frame profile, as the main structure of the casement window, provide the installation base for the decorative trim 5.

[0028] In this embodiment, the detachable fastener 2 adopts a snap-fit ​​structure, with its snap-fit ​​base integrally formed with the outer surface of the mullion profile 1. This not only effectively ensures the stability of the detachable fastener 2 but also provides a stable support point for the subsequent assembly of the decorative lines 5. The outer side of the snap-fit ​​structure includes hooks extending to both sides. In another embodiment, when the detachable fastener 2 adopts a snap-fit ​​structure, a detachable elongated plate snap-fit ​​can also be used. This plate snap-fit ​​is arranged along the length of the mullion profile 1 and is fixed to the outer surface of the mullion profile 1 by forming methods such as self-tapping screws in the prior art.

[0029] Decorative molding 5 is an independently formed profile with a rectangular structural cavity 4 in its cross-section. The design of the structural cavity 4 not only effectively reduces the overall weight of the decorative molding 5 but also allows connecting brackets to be assembled on its upper and lower ends. Through these connecting brackets, the decorative molding 5 is fixedly connected to the mullion profile 1 on the back side.

[0030] The decorative line 5 has an integrally formed snap-fit ​​groove 3 on the outer side of the short side of the structural cavity 4. In this embodiment, the snap-fit ​​groove 3 is designed with hook grooves that match the hooks extending from both sides of the buckle structure of the detachable fastener 2. Through the precise matching between the hooks on the buckle structure and the hook grooves on the snap-fit ​​groove 3, the decorative line 5 can be securely and conveniently snap-fitted and fixed to the detachable fastener 2 through the snap-fit ​​groove 3.

[0031] The snap-fit ​​assembly structure between the decorative line 5 and the mullion profile 1 not only simplifies the installation process, but also significantly improves installation efficiency and ease of disassembly, effectively reducing maintenance costs.

[0032] In different embodiments, users can select detachable fasteners 2 of different shapes and materials, such as snap-fits, clips, or rotatable latches, according to actual needs, and match them with the snap-fit ​​groove 3 to meet diverse installation requirements. When the detachable fastener 2 adopts a snap-fit ​​or clip-fit ​​structure, in order to improve the structural stability of the connection between the detachable fastener 2 and the snap-fit ​​groove 3, a rubber sleeve can be fitted on the fixing part of the detachable fastener 2 to increase the pre-tightening force and friction, preventing the detachable fastener 2 from accidentally falling off during use, and further improving the safety and stability of the component.

[0033] Furthermore, in another embodiment, to improve the bending strength and overall stability of the decorative line 5, structural reinforcing ribs are pre-embedded in the structural cavity 4 of the decorative line 5. This design effectively enhances the mechanical properties of the decorative line 5, making it less prone to deformation or damage during long-term use.

[0034] In such Figure 2 The embodiment shown illustrates a more complex structural form of the casement window decorative line assembly.

[0035] Specifically, the detachable fastener 2 is replaced with a rotatable latch structure, which is fixed to the outer surface of the mullion profile 1 by self-tapping screws 6. The opposite side of the rotatable latch is designed as a hook, which can engage with the snap-fit ​​groove 3 on the decorative line 5. The structure after it is locked is shown in the figure. Users can easily install and remove the decorative line 5 by rotating the rotatable latch, making the operation simple and quick.

[0036] However, considering that the rotatable latch structure requires openings on the surface of the decorative line 5, in order to maintain the aesthetics of the decorative line 5, a snap-on structure can be provided on the outer side of the decorative line 5.

[0037] Furthermore, considering the limitations imposed by the length of decorative line 5 on operations, decorative line 5 can be designed as a fixed-length, split-type line, such as a single segment of decorative line 5 with a length ≤ 1.5m. It can be pre-assembled on the ground and then hoisted in sections, requiring only locking clips at height. This effectively improves installation efficiency and reduces the risks of working at height. To achieve this effect, adjacent decorative lines 5 can be connected at their ends using concealed connectors 9. The concealed connectors 9 are aluminum alloy rods of the same type as casement window profiles, with an H-shaped cross-section that matches the dimensions of the structural cavity 4 on the cross-section of the decorative line 5. Through the concealed connectors 9, adjacent decorative lines 5 can be tightly and securely connected, maintaining overall aesthetics while improving installation convenience and efficiency.

[0038] Regarding sealing performance, the decorative molding 5 has pre-drilled sealant grooves on both sides of its contact surface with the mullion profile 1 and the window frame profile. After the decorative molding 5 is assembled using the detachable fastener 2, the user can inject sealant 7 into the gaps in the sealant grooves to ensure the structural strength and sealing performance of the connection. This design not only improves the sound and heat insulation of the casement window but also effectively prevents the intrusion of external factors such as rainwater and dust.

[0039] To meet the aesthetic needs of different users, a decorative structural layer is also formed on the outer surface of the decorative line 5. This decorative structural layer can be treated with different materials and processes, such as paint layer, wood grain layer, film layer or decorative cover plate, according to the user's choice, to achieve a variety of decorative effects.

[0040] In addition, this Figure 2 In the illustrated embodiment, the decorative line 5 also has a light strip mounting groove 8 formed on its outer surface. This design provides users with a convenient way to install light strips on the decorative line 5, further enhancing the aesthetics and practicality of the casement window.

[0041] In summary, the detachable casement window decorative line component proposed in this utility model, through the use of a snap-fit ​​design between the detachable fastener and the decorative line, as well as a series of innovative structural and material selections, not only simplifies the installation process, improves installation efficiency and ease of disassembly, but also effectively enhances the stability and sealing performance of the component, meeting the diverse needs of the market.
