[0020] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application. Figures 2-3 The novel conversion frame profile of the present application will be described in detail as follows:

[0021] The novel conversion frame profile comprises a support frame 1 and a side plate 2, the side plate 2 is connected with a casement sash, the support frame 1 comprises an outer surface 101, an outer frame surface 102, a sash surface 103 and an inner surface 104, the side plate 2 is arranged at the turning part of the sash surface 103 and the inner surface 104, the outer wall of the side plate 2 is flush with the inner surface 104 and perpendicular to the sash surface 103, the outer wall of the inner surface 104 is a flat surface, the outer wall of the outer frame surface 102 is provided with an abutting part 1021, the surface of the abutting part 1021 is perpendicular to the outer wall of the inner surface 104, the abutting part 1021 is used for abutting with the clamping plate 601 of the outer frame, the outer wall of the outer surface 101 is provided with a window frame connecting part 1011, the surface of the window frame connecting part 1011 is provided with a clamping head 1012, and the clamping head 1012 is used for butt joint with the clamping groove 602 of the casement outer frame 6.

[0022] The traditional outwardly bent pressing edge structure in the traditional conversion frame is completely abandoned, the problem of surface protrusion after installation is avoided, the connection between the conversion frame and the casement window frame 5, the window guard rail and other components is more smooth and beautiful, and the attachment and installation of the window guard rail are provided with an unobstructed fitting surface. The surface of the abutting portion 1021 can be tightly fitted with the clamping head 1012 of the casement outer frame 6. Compared with the traditional conversion frame which is in contact with the clamping plate 601 of the casement outer frame 6 through the supporting leg, the deformation of the supporting leg is avoided from the root, the clamping head 1012 can be directly and accurately connected with the clamping groove 602 of the casement outer frame 6, the conversion frame does not need other auxiliary fixing measures to be fixed with the outer frame, the contact area between the conversion frame and the casement outer frame 6 is increased, the connection strength between the conversion frame and the casement outer frame 6 is significantly improved, the structure after installation is stable, and the bearing capacity and stability of the conversion frame are enhanced. In addition, the supporting leg structure is cancelled, the inner space gap width between the conversion frame and the casement outer frame 6 is reduced, a self-tapping screw with a shorter length can be used for fastening connection, and the cost of auxiliary materials is reduced.

[0023] The outer wall of the outer fitting surface 101 is further provided with a sash connecting portion 1013 which is parallel to the window frame connecting portion 1011. When the casement outer frame 6 is assembled with the support frame body 1, the sash connecting portion 1013 and the window frame connecting portion 1011 are provided with a glue injection area 1014. After the sealant 3 is injected into the glue injection area 1014, the sealant 3 flows into the clamping groove 602 of the casement outer frame 6 and fills the gap between the sash connecting portion 1013 and the casement outer frame 6, thereby enhancing the connection tightness between the conversion frame and the casement outer frame 6 and effectively improving the waterproof and dustproof performance of the window body. The existence of the glue injection area 1014 enables the window body to better maintain the comfort and safety of the indoor environment in the face of severe weather conditions.

[0024] The outer wall of the sash connecting surface 103 is provided with a conversion frame notch 1031 which is used for increasing functional components such as sound-absorbing cotton and heat-insulating cotton between the conversion frame and the casement sash, thereby enhancing the use experience of the entire door and window. The conversion frame notch 1031 is composed of two opposite clamping hooks 1131. The clamping hook 1131 close to the outer fitting surface 101 is arranged at the turning position between the sash connecting portion 1013 and the sash connecting surface 103, and the outer wall of the clamping hook 1131 is flush with the surface of the sash connecting portion 1013. After the conversion frame and the casement sash are installed, the rubber strip 4 of the casement sash presses the sash connecting portion 1013 and the outer wall of the clamping hook 1131 close to the outer fitting surface 101. The inner wall of the side plate 2 is provided with a sealing groove 7 for installing the rubber strip 4. The sealing groove 7 is located at the edge of the side plate 2 away from the support frame body 1, so as to seal the conversion frame and the casement sash and effectively prevent foreign matters such as dust and water vapor from entering the cavity between the conversion frame and the casement sash.

[0025] The inner space gap width of the turning frame of the embodiment after installation with the casement frame 6 is 5mm, compared with the installation gap of 12.5mm of the traditional turning frame, is significantly reduced, so that the turning frame and the casement frame 6 can be fastened and connected by using shorter self-tapping screws, not only the closer splicing effect is realized, but also the overall structure and stability are enhanced.

[0026] In terms of size design, the total width of the turning frame of the embodiment is 78.5mm, which is reduced by 1mm compared with the traditional turning frame of 79.5mm, not only the daylighting area of the window glass is increased, but also the overall aesthetic is improved.

[0027] In addition, after detailed calculation, the meter weight of the new conversion frame profile is 0.937kg / m, which is reduced compared with the original conversion frame profile of 0.946kg / m, while ensuring the structural strength, the economy of material use is realized, and the market competitiveness of the product is further improved.

[0028] It is obvious for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting, the scope of the present application is defined by the appended claims rather than the above description, and therefore all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application. Any reference signs in the claims should not be regarded as limiting the claims involved.
