Description

Technical Field

[0001] This utility model relates to the technical field of thermal break strips for thermally broken aluminum alloy doors and windows, specifically a thermal break strip for thermally broken aluminum alloy doors and windows. Background Technology

[0002] Currently, the thermal break aluminum profiles widely used in the market are generally mechanically connected to the aluminum profiles through a rolling process during manufacturing to improve the thermal insulation performance of the profiles. However, for some thermal break aluminum products with special structures, problems such as deformation and skewness of the thermal break strips often occur during the rolling process. Especially in structures with multiple thermal break strips, it is easier for one thermal break strip to remain straight while another becomes skewed.

[0003] This deformation not only affects the consistency of product appearance, but also makes it difficult to guarantee product assembly quality and structural stability, thereby affecting its thermal insulation performance and service life. One of the main reasons for this problem is that the thermal insulation strip is fixed in the profile before rolling, which restricts its free adjustment and coordination during the rolling process, and easily leads to uneven stress and deformation. Utility Model Content

[0004] This invention provides a thermal break strip for thermally broken aluminum alloy doors and windows, which can effectively solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a thermal break strip for thermally broken aluminum alloy doors and windows, comprising a left frame and a right frame, wherein limit buckles are provided at the top and bottom of the left frame and the right frame;

[0006] A heat-insulating straight strip is engaged between the two bottom limiting buckles, and a heat-insulating oblique strip is flexibly connected to one side of the bottom end of the heat-insulating straight strip. A limiting protrusion is provided at the bottom edge of the heat-insulating oblique strip.

[0007] A limit stop is provided on the inner side of the right frame at the position of the limit protrusion.

[0008] According to the above technical solution, the upper sealing strip is attached to the limiting buckle at the top of the left frame and the right frame, and the four limiting buckles are the same in shape and size.

[0009] According to the above technical solution, the heat insulation straight strip, the heat insulation diagonal strip and the limiting protrusion are manufactured as a single unit, and the limiting protrusion can drive the heat insulation diagonal strip to be locked at the limiting point position.

[0010] Compared with the prior art, the advantages of this utility model are as follows: The structure of this utility model is scientific and reasonable, and it is safe and convenient to use. By improving the structure of the thermal insulation strip, the buckle is designed to be in the open state before rolling, so that the thermal insulation strip can maintain the same matching method as ordinary thermally broken aluminum profiles during the rolling process. This effectively avoids the problem of thermal insulation strip skewing or deformation caused by structural constraints. After rolling, the buckle on the thermal insulation strip is engaged and fixed with the protrusion on the aluminum profile to achieve the final positioning and connection of the structure.

[0011] This improved solution has the following beneficial effects:

[0012] Improve the stability of the rolling process: During the rolling process, the heat insulation strip is not forcibly fixed and can be freely matched, effectively avoiding problems such as skewing and deformation caused by uneven stress;

[0013] Improve product appearance consistency and aesthetics: After the thermal insulation strip is rolled, it fits tightly with the profile, avoiding unevenness on the surface;

[0014] Ensuring structural connection strength and thermal insulation performance: The snap-fit ​​structure after roll forming can firmly lock the aluminum material and thermal insulation strip, improving overall stability and thermal insulation performance;

[0015] Enhance the controllability and yield of the production process: The rolling operation is closer to the traditional thermal break aluminum process, which facilitates process standardization and reduces the scrap rate;

[0016] In summary, this structural design optimizes the fit between the thermal insulation strip and the aluminum profile, effectively solving the problems of rolling deformation and quality control difficulties in traditional structures, and has good application prospects and practical value.

[0022] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0023] Example: Figs. 1-2 As shown, this utility model provides a technical solution: a thermal insulation strip for thermally broken aluminum alloy doors and windows, including a left frame 1 and a right frame 2. Limiting buckles 4 are provided at the top and bottom of the left frame 1 and the right frame 2. In order to improve the sealing performance, the limiting buckles 4 at the top of the left frame 1 and the right frame 2 are engaged with an upper sealing strip 3, and the four limiting buckles 4 are the same in shape and size.

[0024] A heat-insulating straight strip 5 is snapped between the two bottom limit buckles 4. A heat-insulating diagonal strip 6 is flexibly connected to one side of the bottom end of the heat-insulating straight strip 5. A limit protrusion 7 is provided at the bottom edge of the heat-insulating diagonal strip 6.

[0025] A limit point 8 is provided on the inner side of the right frame 2 at the position of the limit protrusion 7.

[0026] To facilitate production, the heat insulation straight strip 5, the heat insulation diagonal strip 6, and the limiting protrusion 7 are made as a single unit, and the limiting protrusion 7 can drive the heat insulation diagonal strip 6 to be locked at the limiting point 8.

[0027] The working principle and usage process of this utility model are as follows: During production, the structure of the thermal insulation strip is improved. The upper sealing strip 3 between the left frame 1 and the right frame 2 is first inserted into the top limiting buckle 4. Then, the thermal insulation straight strip 5 is inserted into the bottom limiting buckle 4 between the left frame 1 and the right frame 2. This allows the thermal insulation strip to maintain the same matching method as ordinary thermally broken aluminum profiles during the rolling process, thereby effectively avoiding the problem of thermal insulation strip skewing or deformation caused by structural constraints. After the rolling is completed, the limiting protrusion 7 of the thermal insulation diagonal strip 6 is engaged and fixed with the limiting buckle on the right frame to achieve the final positioning and connection of the structure.
