[0002] The door and window frame profile is one of the main materials for doors and windows. Currently, broken bridge aluminum doors and windows are more common. For door and window profile materials, in the prior art, after retrieval, the utility model patent with the Chinese patent publication number CN216767113U discloses a structure of a broken bridge aluminum door and window frame profile. As Figure 1 shown, it mainly includes an outdoor side frame aluminum profile a, an inner core profile b, and an indoor side frame aluminum profile c. The inner core profile b is located between the outdoor side frame aluminum profile a and the indoor side frame aluminum profile c. A composite foot d is fixedly arranged on the inner core profile b. Both the outdoor side frame aluminum profile a and the indoor side frame aluminum profile c are provided with clamping grooves. The inner core profile b is a glass fiber reinforced composite profile. A longitudinal strip groove e is arranged along the length direction on the composite foot d of the inner core profile b.

[0003] In the prior art, for a door and window frame profile similar to the above technical solution, it is found that there are areas for improvement during actual implementation: the longitudinal strip groove arranged along the length direction on the composite foot of the inner core profile easily causes the composite foot of the inner core profile to split and misalign due to the strip groove, which easily affects the strength of the composite foot. Summary of the Utility Model

[0004] In view of the deficiencies and defects existing in the prior art, the purpose of the present utility model is to provide a door and window frame profile, which solves the problem that the longitudinal strip groove on the composite foot of the inner core profile in the existing door and window frame profile easily causes the composite foot to split and misalign, and easily affects the strength of the composite foot.

[0005] To solve the above technical problems, the present utility model adopts the following technical solution: A door and window frame profile includes an outdoor side frame aluminum profile, an inner core profile, and an indoor side frame aluminum profile. The inner core profile is located between the outdoor side frame aluminum profile and the indoor side frame aluminum profile. A composite foot is fixedly arranged on the inner core profile. Both the outdoor side frame aluminum profile and the indoor side frame aluminum profile are provided with clamping grooves. A toothed strip slot is arranged along the length direction on the composite foot of the inner core profile. Two transverse ribs are arranged in the center of the inner side of the inner core profile. A heat insulation strip is arranged between the two transverse ribs. Two longitudinal ribs are arranged on the front and back sides of the two transverse ribs on the inner side of the inner core profile. A sound insulation strip is arranged between the two longitudinal ribs.

[0006] As a further improvement of the present utility model, a first vertical plate is arranged in the middle of the two composite feet on the front and back sides of the inner core profile. A second vertical plate corresponding to the first vertical plate for clamping connection is arranged on one side of the outdoor side frame aluminum profile and the indoor side frame aluminum profile close to the inner core profile.

[0007] As a further improvement of the present utility model, a clamping groove is provided on the second vertical plate, and a clamping block corresponding to the clamping groove is provided on the first vertical plate.

[0008] As a further improvement of the present utility model, the left and right ends of each of the transverse ribs are bent towards the side away from the other transverse rib.

[0009] As a further improvement of the present utility model, serrated grooves are provided on the facing sides of the two transverse ribs.

[0010] Compared with the prior art, the present utility model has the following advantages:

[0011] 1. By providing a toothed slotted seam along the length direction on the composite foot of the inner core profile, the two sides of the toothed slotted seam on the composite foot are clamped together. Compared with the structure of providing a longitudinal slotted seam on the composite foot in the prior art, it can, to a certain extent, avoid the dislocation and sliding of both sides of the composite foot, and improve the connectivity and overall strength of the composite foot on both sides of the toothed slotted seam.

[0012] By providing transverse ribs and longitudinal ribs on the inner side of the inner core profile, the overall strength of the inner core profile is greatly improved in the transverse and longitudinal directions. In addition, by providing a heat insulation strip between the two transverse ribs, the heat insulation performance of the door and window frame material can be improved, and by providing a sound insulation strip between the two longitudinal ribs, the sound insulation performance of the door and window frame material can be improved.

[0013] 2. By providing a first vertical plate in the middle of the two composite feet on the front and rear sides of the inner core profile, and providing a second vertical plate corresponding to the first vertical plate for clamping on the side of the outdoor side frame aluminum profile and the indoor side frame aluminum profile close to the inner core profile, the connectivity between the inner core profile and the outdoor side frame aluminum profile and the indoor side frame aluminum profile is improved, and the overall connection strength is improved.

[0014] 3. By providing serrated grooves on the facing sides of the two transverse ribs, the embedding connectivity between the transverse ribs and the heat insulation strip is improved, and the overall strength is improved. BRIEF DESCRIPTION OF THE DRAWINGS
