Description

Technical Field

[0001] The utility model relates to the technical field of doors and windows, in particular to an integrated conversion frame structure. Background Art

[0002] Most conversion frames in the current industry can be divided into two types. The first type is composed of two cavity profiles connected by insulation strips. The profile accounts for a large proportion, and more corner codes are required, which greatly increases the weight of the entire window. At the same time, the cost is high and the processing is relatively troublesome. The other type of conversion frame is a single-piece profile. Although compared with the first type of conversion frame, the required profile weight per meter is reduced under the same conditions, the sealing performance is improved, and the processing is relatively easy, but the conversion frame is a profile as a whole, lacks insulation materials, and has poor thermal insulation performance.

Although the patent can achieve the sealing effect between the window sash and the window frame when closed through the coordinated use of the window frame, the window sash, the central strip and the glass outer blade-type strip, there are still certain limitations on the thermal insulation and heat insulation performance of the conversion frame.

The structure is simple, the two sides of the base 3 are respectively matched with the conversion frame profile 7 and the conversion frame buckle, the base 3 is provided with a filling piece inside, which plays a role in heat insulation, a central water vapor rubber strip is arranged between the conversion frame buckle cover 4 and the conversion frame profile 7, the central water vapor rubber strip is located above the base 3 and matched with the outward opening window sash 6, so as to improve the sealing performance of the structure and solve the problem of poor heat insulation performance of the integrated conversion frame profile 7 in the prior art.

[0028] Specifically, the conversion frame profile 7 has only a single cavity, which accounts for a small proportion, and the number of corner codes used is small, which greatly reduces the weight of the entire window and reduces the cost. After the base 3 is installed on the conversion frame profile 7, a filler is filled between the base 3 and the conversion frame profile 7. After the filler meets the installation requirements, the conversion frame buckle cover 4 is buckled on the base 3, and then the caulking strip and the central water vapor strip are installed to complete the installation of the conversion frame.

[0029] like Figure 1 As shown, in Example 2, an integrated conversion frame structure, the conversion frame profile 7 is a metal profile, and the metal material includes but is not limited to stainless steel and aluminum. One side of the conversion frame profile 7 is provided with a support plate 7-1 that matches the window frame 1, and the other side of the conversion frame profile 7 is provided with two U-shaped grooves 7-2 with openings facing each other. The conversion frame profile 7 is installed on the window frame 1, and the support plate 7-1 is located on the upper part of the conversion frame profile 7 and is mounted on the window frame 1. The vertical surface of the support plate 7-1 and the vertical surface of the window frame 1 are both located on the same vertical plane.

One side of the lower part of the central water vapor rubber strip is clamped on the leg 4-1 of the upper part of the E-shaped structure, and the other side of the lower part of the central water vapor rubber strip is clamped between the conversion frame profile 7 and the base 3, which is used to fix the central water vapor rubber strip.
