Description

Technical Field

[0001] This utility model relates to a heat insulation structure between a cover and a profile, belonging to the technical field of building doors and windows. Background Technology

[0002] With the continuous development of technology, more and more building door and window profiles are adopting thermal break structures, which are widely recognized by consumers for their excellent thermal insulation performance. During the assembly process, some profiles inevitably have exposed end faces. The usual practice is to use clips to conceal these end faces, thus improving the overall aesthetics. However, some clips directly connect the interior and exterior metal profiles, compromising the thermal break function and reducing the overall insulation performance of the doors and windows. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a heat insulation structure between the cover and the profile. The heat insulation structure between the cover and the profile adopts a non-metallic cover base as a transition structure, thereby realizing that the cover has a thermal break structure and ensuring the overall heat insulation effect of the door and window.

[0004] To solve the above problems, the specific technical solution of this utility model is as follows: a heat insulation structure between the cover and the profile, wherein a U-shaped groove I is provided on the indoor end face of the profile, and an extension arm is provided on the outdoor end face; a U-shaped groove II is provided on one side of the cover, and the position of the U-shaped groove II corresponds to that of the U-shaped groove I; the other side of the cover is sealed and engaged with the extension arm; a non-metallic cover base is provided between the U-shaped groove II and the U-shaped groove I, and positioning legs are provided on both sides of the cover base, and the positioning legs on both sides are engaged with the U-shaped groove I or the U-shaped groove II respectively.

[0005] The U-shaped slot I and U-shaped slot II have the same opening structure, both having inwardly curved edges; the outer surface of the positioning leg is provided with a positioning groove, and each curved edge is engaged in the corresponding positioning groove.

[0006] The extension arm has a sealing strip groove at its end; the outdoor end of the cover is flush with the extension arm and has an L-shaped clamping plate that engages with the sealing strip groove, with the bent end of the L-shaped clamping plate engaging with the sealing strip groove.

[0007] A sealing strip is provided at the junction of the L-shaped card plate and the inner surface of the cover.

[0008] The thermal insulation structure between the cover and the profile in this application adopts the above-described structure, which has the following advantages:

[0009] 1. Both the profile and the cover are made of metal, and the profile has an internal thermal break structure. The heat transfer from the outside is blocked by the base of the cover, thereby improving the overall heat insulation effect of the doors and windows.

[0010] 2. The cover base adopts a positioning support leg structure to achieve the snap-fit ​​connection between the profile and the cover, which not only ensures the connection between the cover and the profile, but also improves assembly efficiency;

[0011] 3. An L-shaped retaining plate is provided at the end of the cover, which not only further improves the connection stability with the profile, but also seals the cover with a sealing strip, forming a heat insulation cavity between the cover and the profile. Attached Figure Description

[0013] Figure 2 for Figure 1 AA sectional view. Detailed Implementation

[0014] like Figure 1 and Figure 2 As shown, a heat insulation structure between a cover and a profile is provided. A U-shaped groove I3 is provided on the indoor end face of the profile 1, and an extension arm 4 is provided on the outdoor end face. A U-shaped groove II5 is provided on one side of the cover 2, and the position of the U-shaped groove II5 corresponds to that of the U-shaped groove I3. The other side of the cover 2 is sealed and engaged with the extension arm 4. A non-metallic cover base 6 is provided between the U-shaped groove II5 and the U-shaped groove I3. Positioning legs 7 are provided on both sides of the cover base 6, and the positioning legs 7 on both sides are engaged with the U-shaped groove I3 or the U-shaped groove II5 respectively.

[0015] The U-shaped slots I3 and II5 have the same opening structure, both having inwardly curved edges; the outer surface of the positioning leg 7 is provided with positioning grooves, and each curved edge is engaged in the corresponding positioning groove. This achieves a tight engagement between the cover 2 and the profile 1.

[0016] The extension arm 4 is provided with a sealing strip groove 8 at its end to ensure the sealing performance of the connection; the outdoor end of the cover 2 is flush with the extension arm 4 and has an L-shaped clamping plate 9 that engages with the sealing strip groove 8. The bent end of the L-shaped clamping plate 9 engages with the sealing strip groove 8 to further ensure the secure engagement of the cover.

[0017] A sealing strip 10 is provided at the junction of the L-shaped card plate 9 and the inner surface of the cover 2 to further improve the overall sealing performance.
