The minimalist style door (window) frame installation only needs to be fixed and sealed between the door (window) frame and the opening. When further decoration is required, the so-called door (window) cover is needed to cover the inner and outer facades of the opening plane and the edge of the opening.

[0003] Commonly used door cover profiles can be divided into wood, aluminum alloy, rigid polyvinyl chloride, foamed polyvinyl chloride, etc. according to the material. According to the connection method between door cover profiles and between door cover profiles and door (window) frames, they can be divided into non-card splicing and card splicing. Card splicing requires the use of glue or nails to splice profiles, which is commonly used in wood and foamed plastic profiles; card splicing can be subdivided into self-locking card splicing with gaps and self-locking card splicing without gaps. Among them, self-locking card splicing with gaps is more commonly used in rigid polyvinyl chloride profiles and aluminum alloy profiles, and is rarely used in foamed plastic profiles due to material and structural reasons.

[0027] Example 2

[0028] like Figure 1-Figure 4 As shown, based on the contents of Example 1, this embodiment discloses a door and window frame foam plastic profile, including a door and window frame main profile 11 and a door and window frame decorative profile 12. The door and window frame decorative profile 12 is detachably installed on both sides of the door and window frame main profile 11 through the above-mentioned elastic self-locking splicing profile.

[0029] Specifically, both sides of the door and window frame main profile 11 are formed with slot profile installation slots 13 for installing the self-locking slot profile 1.

[0030] Example 3

[0031] Based on the content of Example 2, this embodiment provides a foam plastic profile for a door and window frame, wherein an outwardly extending transition edging 14 is provided on the outer edge of the self-locking slot profile 1, and the transition edging 14 is connected to the outer edging of the door and window frame decorative profile 12 as a whole and has a smooth transition.

[0032] Example 4

[0033] Based on the installation requirements of door and window frame decorative profiles 12 of different specifications, the self-locking claw profile 2 is adaptively optimized and designed;

[0034] For the door and window frame decorative profiles 12 with high decorative requirements such as the entrance door, the specifications of the door and window frame decorative profiles 12 selected are relatively large.
