[0020] According to requirements, the liner 1 is a well-known prior art, such as channel steel or C-shaped steel. The liner 1 is fixedly installed in the steel liner cavity 3 through a number of connectors distributed at intervals. The upper decorative layer 13 and the left end of the lower decorative layer 13 both extend to the left and right sides of the PVC profile 2. The decorative layer 13 can be formed by the embossing device of the co-extrusion die. The PVC profile 2 is formed by double-sided co-extrusion. The large-surface co-extrusion inlet is arranged above the PVC profile 2, and the small-surface co-extrusion inlet is arranged at the lower right of the PVC profile 2.

[0021] During use, as needed, at least one casement mullion structure is fixedly installed in the window frame. Then, glass is installed in the left installation groove 11 and the right installation groove 12. By providing the steel liner cavity 3 and the liner 1, the strength of the PVC profile 2 can be improved. The setting of the partition cavity can not only improve the strength and heat preservation effect of the PVC profile 2, but also facilitate the forming of the casement frame mullion structure.

During use, through such a setting, the strength between the partition cavities inside the PVC profile 2 can be improved.

[0024] Embodiment 3: As an optimization of the above embodiment, as shown in the appendix Figure 1 As shown, the left installation groove 11 is in a U shape with an opening to the left, and the width of the upper side of the left installation groove 11 is greater than the width of the lower side of the left installation groove 11. The upper corner of the left installation groove 11 is recessed upward to the right to form an arc-shaped left drainage groove 15, and the upper corner of the right installation groove 12 is recessed upward to the left to form a right drainage groove 16 symmetrically arranged with the left drainage groove 15.

[0025] According to requirements, a number of first inner drainage holes communicating with the second separation cavity 5 are spaced along the length direction at the bottom of the left drainage groove 15, and a number of second inner drainage holes communicating with the third separation cavity 6 are spaced along the length direction at the bottom of the right drainage groove 16. A number of first outer drainage holes communicating with the second separation cavity 5 are spaced on the upper surface of the left part of the PVC profile 2, and a number of second outer drainage holes communicating with the third separation cavity 6 are spaced on the upper surface of the right part of the PVC profile 2. The first outer drainage holes and the first inner drainage holes are spaced apart, and the second outer drainage holes and the second inner drainage holes are spaced apart. During use, by providing the left drainage groove 15 and the right drainage groove 16, it is possible to prevent excessive water accumulation in the left installation groove 11 and the right installation groove 12 from flowing into the room. During heavy rain, rainwater can be discharged outdoors through the drainage grooves, inner drainage holes, and outer drainage holes. The inverted Y-shaped rib plate 14 facilitates the smooth discharge of rainwater flowing into the second separation cavity 5, and at the same time can also support the drainage groove, preventing the PVC profile 2 corresponding to the drainage groove from deforming, and preventing the accumulated water in the installation groove from damaging the sealant or rubber strip at the edge of the glass in the installation groove, thereby extending the service life of the sealant or rubber strip.

[0026] Embodiment 4: As an optimization of the above embodiment, as shown in the appendix Figure 1 As shown, the inner wall of the left installation groove 11 corresponding to the left side of the left drainage groove 15 is recessed upward to form a T-shaped left connection groove 17 that is wider at the top and narrower at the bottom, and the upper inner wall of the right installation groove 12 is formed with a right connection groove 18 symmetric to the left connection groove 17.

[0027] During use, by providing the left connection groove 17 and the right connection groove 18, a sealing strip can be installed in the connection groove to facilitate improving the sealing performance between the PVC profile 2 and the glass, thereby enhancing the protection performance of the window.

[0028] Embodiment 5: As an optimization of the above embodiment, as shown in the appendix Figure 1 、 2 、3, the lining 1 is in a U-shaped with an opening to the right. The lower inner wall of the lower part of the steel lining cavity 3 corresponding to the position below the right connection groove 18 is provided with two left positioning ridges 19 spaced up and down.
