[0032] Example 1: Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 According to one embodiment of this utility model, a system door and window profile includes a door frame profile 1, a screen profile 2, and a mullion profile 3. One side of the screen profile 2 is connected to the mullion profile 3, and the other side is in contact with the door frame profile 1. The door frame profile 1, the screen profile 2, and the mullion profile 3 form a four-way sealed connection.

[0033] The door frame profile 1 includes an outer door frame profile 11, an inner door frame profile 12, and a snap strip 13. The outer door frame profile 11 and the inner door frame profile 12 are connected by a heat insulation strip 4. The snap strip 13 is inserted into the upper part of the inner door frame profile 12. The connection between the outer door frame profile 11 and the inner door frame profile 12 forms three steps 14 with the screen profile 2. A sealing cavity 5 is provided between the steps 14.

[0034] The screen window profile 2 includes a screen window frame profile 21, an inner frame profile 22, an outer frame profile 23, and a small snap strip 24. The small snap strip 24 is inserted into the upper inner side of the screen window frame profile 21, and the lower part is connected to the inner frame profile 22. The inner frame profile 22 and the outer frame profile 23 are connected by a heat insulation strip 4. A sealing cavity 5 is provided at the contact point between the inner frame profile 22 and the inner frame profile 12 of the door leaf. A third sealing strip 8 and a fourth sealing strip 9 are respectively connected to the sealing cavity 5.

[0035] The mullion profile 3 includes a mullion outer frame profile 31, a mullion inner frame profile 32, and a decorative strip profile 33. The mullion outer frame profile 31 and the mullion inner frame profile 32 are connected by a thermal insulation strip 4. The decorative strip profile 33 is snapped onto the outside of the mullion inner frame profile 32, and the inside of the mullion profile 3 is connected to the screen profile 2.

[0036] When the door frame profile 1, screen profile 2 and mullion profile 3 are closed, they form four continuous sealing lines through stepped connection, and when the hardware lock points are closed, the first sealing strip 6, the second sealing strip 7, the third sealing strip 8 and the fourth sealing strip 9 are pressed simultaneously.

[0037] Furthermore, through the four-layer sealing connection design between the door frame profile 1, the screen profile 2, and the mullion profile 3, four continuous sealing lines are formed, which can prevent the penetration of air, moisture, and dust, and significantly improve the overall sealing performance of the doors and windows.

[0038] The design of the sealing cavity 5 in conjunction with the first sealing strip 6, the second sealing strip 7, the third sealing strip 8 and the fourth sealing strip 9, when locked, is synchronously pressed by the hardware locking points to form a multi-layer sealing barrier, which effectively prevents rainwater leakage and avoids affecting the indoor environment.

[0039] The stepped structure 14 at the contact point between the door frame profile 1 and the screen profile 2 reduces the space for dust accumulation, and the smooth surface of the sealing cavity 5 facilitates daily cleaning and maintenance, reducing the accumulation of dirt and grime.

[0040] The door frame profile 1, the screen window profile 2, and the mullion profile 3 all form a thermal break structure through the thermal break strip 4, which blocks heat transfer, improves the thermal insulation performance of the doors and windows, and reduces building energy consumption.

[0041] When the hardware locking points are closed, the first sealing strip 6, the second sealing strip 7, the third sealing strip 8, and the fourth sealing strip 9 are pressed simultaneously to ensure that the sealing strips are evenly compressed, thereby enhancing the sealing durability and closing stability.

[0042] Example 2: Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5In one embodiment of this utility model, the outer frame profile 11 and the inner frame profile 12 of the door leaf are connected by a heat insulation strip 4 to form a heat insulation bridge structure.

[0043] The inner frame profile 22 and the outer frame profile 23 of the screen window profile 2 form a thermal break structure through the thermal insulation strip 4;

[0044] The outer frame profile 31 and the inner frame profile 32 of the mullion are connected by a thermal break strip 4 to form a thermal break structure.

[0045] The surface of the sealed cavity 5 has a smooth structure;

[0046] The first sealing strip 6, the second sealing strip 7, the third sealing strip 8 and the fourth sealing strip 9 are subjected to uniform force when locked, forming a continuous sealing barrier;

[0047] Furthermore, by using thermal break strips 4 to form a thermal break structure between the door leaf outer frame profile 11 and the door leaf inner frame profile 12, the screen window profile 2 inner frame profile 22 and the outer frame profile 23, and the mullion outer frame profile 31 and the mullion inner frame profile 32, the heat transfer between the profiles is effectively blocked, significantly improving the overall thermal insulation performance of the doors and windows, reducing the thermal bridge effect, and further reducing building energy consumption;

[0048] The surface of the sealed cavity 5 has a smooth structure, which reduces dust adhesion, facilitates quick cleaning and wiping, avoids dirt residue, and improves daily maintenance efficiency;

[0049] When locked, the first sealing strip 6, the second sealing strip 7, the third sealing strip 8, and the fourth sealing strip 9 are simultaneously and evenly stressed through the hardware locking points, forming a continuous sealing barrier without interruption. This avoids deformation or wear of the sealing strips caused by local stress concentration, extends the service life of the sealing strips, and ensures long-term sealing effect.

[0050] Working principle: Through the four-layer sealing connection design between the door frame profile 1, screen profile 2, and mullion profile 3, four continuous sealing lines are formed, which can prevent the penetration of air, moisture, and dust, significantly improving the overall sealing performance of the door and window. The design of the sealing cavity 5 in conjunction with the first sealing strip 6, the second sealing strip 7, the third sealing strip 8, and the fourth sealing strip 9, when locked, is simultaneously pressed by the hardware locking points, forming multiple sealing barriers, effectively preventing rainwater leakage and avoiding impact on the indoor environment. The stepped structure 14 at the contact between the door frame profile 1 and the screen profile 2 reduces the space for dust accumulation, and the smooth surface of the sealing cavity 5 facilitates daily cleaning and maintenance, reducing dirt accumulation. The door frame profile 1, screen profile 2, and mullion profile 3 all form a thermal break structure through the thermal insulation strip 4, blocking heat transfer, improving the thermal insulation performance of the door and window, and reducing building energy consumption. When the hardware locking points are closed, the first sealing strip 6, the second sealing strip 7, the third sealing strip 8, and the fourth sealing strip 9 are simultaneously pressed, forming multiple sealing barriers, effectively preventing rainwater leakage and avoiding impact on the indoor environment. The sealing strips 7, 8, and 9 ensure uniform pressure on the sealing strips, enhancing sealing durability and closure stability. The door leaf outer frame profile 11 and inner frame profile 12, the screen window profile 2 inner frame profile 22 and outer frame profile 23, and the mullion outer frame profile 31 and inner frame profile 32 all form a thermal break structure via the thermal break strip 4, effectively blocking heat transfer between the profiles, significantly improving the overall thermal insulation performance of the doors and windows, reducing the thermal bridging effect, and further reducing building energy consumption. The sealing cavity 5 has a smooth surface, reducing dust adhesion, facilitating quick cleaning and wiping, preventing dirt residue, and improving daily maintenance efficiency. When locked, the first sealing strip 6, second sealing strip 7, third sealing strip 8, and fourth sealing strip 9 are simultaneously and evenly stressed through the hardware locking points, forming a continuous, uninterrupted sealing barrier, preventing deformation or wear of the sealing strips due to localized stress concentration, extending the service life of the sealing strips, and ensuring long-term sealing performance.
