Description

Technical Field

[0001] This utility model relates to the field of profile technology, specifically to a thermal insulation composite profile. Background Technology

[0002] Aluminum profiles, due to their lightweight, high strength, corrosion resistance, ease of processing and forming, and rich surface treatment options, have become one of the core materials for modern building doors, windows, curtain walls, and structural frames. Especially in high-rise buildings, public facilities, and high-end residences, aluminum alloy profiles are widely used in window frames, door panels, and curtain wall framing due to their excellent mechanical properties and aesthetics. In the field of building doors and windows, sliding doors and windows are a common type, and their structural design plays a crucial role in their performance. Aluminum profiles, due to their good strength and corrosion resistance, are often used as the main frame material for sliding doors and windows. To improve the thermal insulation performance of sliding doors and windows, thermal break strips are usually installed between the aluminum profiles.

[0003] However, as Figure 1 As shown, in existing conventional sliding door and window structures, the protruding weatherstripping at the lower end of the thermal break can interfere with the bonding of the aluminum profile and the thermal break. When attempting to tightly bond the aluminum profile and the thermal break, the protruding weatherstripping hinders effective contact and adhesion between the two, making the bonding process difficult and preventing the achievement of an ideal connection. This not only limits the flexibility of combining aluminum profiles and thermal break materials but also reduces the thermal insulation effect. Utility Model Content

[0030] Example 1

[0031] like Figures 2-5As shown, a thermal insulation composite profile according to an embodiment of the present invention includes a first frame 1, a second frame 2, and a thermal insulation component 3. The first frame 1 and the second frame 2 are symmetrically arranged. One end of the thermal insulation component 3 is detachably connected to the first frame 1, and the end of the thermal insulation component 3 away from the first frame 1 is detachably connected to the second frame 2. The thermal insulation component 3 includes a first thermal insulation strip 31, a second thermal insulation strip 32, a thermal insulation block 33, and an aluminum frame 34. The two ends of the first thermal insulation strip 31 are detachably connected to the first frame 1 and the second frame 2, respectively. The second thermal insulation strip 32 is detachably connected to the first frame 1 and the second frame 2, respectively. The thermal insulation block 33 is disposed between the first thermal insulation strip 31 and the second thermal insulation strip 32. The aluminum frame 34 is detachably connected to the side of the second thermal insulation strip 32 away from the first thermal insulation strip 31. By setting up a heat insulation component 3, which includes a first heat insulation strip 31, a second heat insulation strip 32, a heat insulation block 33, and an aluminum frame 34, the first and second heat insulation strips 31 and 32 act as longitudinal heat insulation barriers, providing initial heat insulation. The heat insulation block 33 forms a core heat insulation layer, blocking the heat conduction path. The detachable connection between the second heat insulation strip 32 and the aluminum frame 34 allows for a smooth composite process, fully realizing the ideal connection between the two. Furthermore, existing exposed heat insulation strips are monochromatic and cannot match the aluminum profile. In this embodiment, a composite connection between the aluminum frame 34 and the second heat insulation strip 32 is implemented, resulting in a more uniform overall color of the profile and improving its aesthetics.

[0032] As a preferred embodiment of this utility model, it may also have the following additional technical features: a first receiving groove 11 is provided at one end of the first frame 1, a second receiving groove 21 is provided at one end of the second frame 2, one end of the first heat insulation strip 31 is engaged with the first receiving groove 11, and the end of the first heat insulation strip 31 away from the first receiving groove 11 is engaged with the second receiving groove 21, ensuring the stability of the first heat insulation strip 31. Under external force or during long-term use, it is not easy to loosen or fall off, thus ensuring the service life and reliability of the profile. A first sealing strip 12 is provided between the first receiving groove 11 and the first heat insulation strip 31, and a second sealing strip 22 is provided between the second receiving groove 21 and the first heat insulation strip 31. This can effectively fill the gap between the first heat insulation strip 31 and the receiving groove, preventing the penetration of air, moisture and other substances, thereby significantly improving the sealing performance of the profile. This not only helps to reduce the heat transfer between indoors and outdoors and improve the heat insulation effect, but also prevents rainwater, dust and other substances from entering the interior of the profile, protecting the internal structure from corrosion and further extending the service life of the profile.

[0033] As a preferred embodiment of this utility model, it may also have the following additional technical features: a third receiving groove 13 is provided at one end of the first frame 1, a fourth receiving groove 23 is provided at one end of the second frame 2, one end of the second heat insulation strip 32 is engaged with the third receiving groove 13, and the end of the second heat insulation strip 32 away from the third receiving groove 13 is engaged with the fourth receiving groove 23, ensuring the stability of the second heat insulation strip 32. Under external force or during long-term use, it is not easy to loosen or fall off, thus ensuring the service life and reliability of the profile. A third sealing strip 14 is provided between the third receiving groove 13 and the second heat insulation strip 32, and a fourth sealing strip 24 is provided between the fourth receiving groove 23 and the second heat insulation strip 32. This can effectively fill the gap between the second heat insulation strip 32 and the receiving groove, preventing the penetration of air, moisture and other substances, thereby significantly improving the sealing performance of the profile. This not only helps to reduce the heat transfer between indoors and outdoors and improve the heat insulation effect, but also prevents rainwater, dust and other substances from entering the interior of the profile, protecting the internal structure from corrosion and further extending the service life of the profile.

[0034] As a preferred embodiment of this utility model, it may also have the following additional technical features: the second heat insulation strip 32 includes a snap-fit ​​portion 321 and an extension portion 322, the snap-fit ​​portion 321 and the extension portion 322 are fixedly connected, the extension portion 322 is provided with a snap-fit ​​groove 3221, and the aluminum frame 34 is disposed in the snap-fit ​​groove 3221 and detachably connected to the extension portion 322. In this embodiment, the snap-fit ​​portion 321 is snapped with the first frame 1 and the second frame 2 respectively to achieve limiting and fixing, and the extension portion 322 is used to connect with the aluminum frame 34, so that the composite process of the aluminum frame 34 and the heat insulation strip can proceed smoothly.

[0035] As a preferred embodiment of this utility model, it may also have the following additional technical features: a locking block 3222 is provided on the end of the extension 322 away from the locking part 321, and a plurality of locking slots 341 are provided on the aluminum frame 34. The locking block 3222 is correspondingly provided with each locking slot 341. The second heat insulation strip 32 and the aluminum frame 34 are joined by locking the locking block 3222 into one of the locking slots 341. The position of the aluminum frame 34 can be adjusted in multiple positions according to different needs. The position of the aluminum frame 34 can be precisely adjusted according to the actual installation needs of the doors and windows, the difference in wall thickness or sealing requirements, so as to ensure the installation accuracy and sealing performance of the doors and windows.

[0036] As a preferred embodiment of this utility model, it may also have the following additional technical features: the locking block 3222 is configured in a sawtooth shape, and each slot 341 is formed with a toothed channel that matches the shape of the locking block 3222, which has a certain self-locking function. During normal use, the locking block 3222 is not easy to fall out of the slot 341, further improving the reliability of the connection and reducing the safety hazards caused by connection failure. When it is necessary to maintain the door and window or replace parts, the connection method between the sawtooth locking block 3222 and the toothed slot 341 is also easy to disassemble. Only appropriate force needs to be applied to pull the locking block 3222 out of the toothed slot 341, which is simple and convenient to operate, will not damage the profile, and reduces maintenance costs.

[0037] As a preferred embodiment of this utility model, it may also have the following additional technical features: the heat insulation block 33 includes a rigid heat insulation block 331 and a soft heat insulation block 332. The soft heat insulation block 332 wraps around the rigid heat insulation block 331. One side of the soft heat insulation block 332 abuts against the first heat insulation strip 31, and the side of the soft heat insulation block 332 away from the first heat insulation strip 31 abuts against the second heat insulation strip 32. In this embodiment, the heat insulation block 33 is disposed between the first heat insulation strip 31 and the second heat insulation strip 32 by filling. The rigid heat insulation block 331 is made of rigid foam, and the soft heat insulation block 332 is made of soft foam. The structure of being hard inside and soft outside makes it less likely for the heat insulation strip to deform due to preheating expansion, while effectively reducing air convection. When the rigid foam core expands slightly due to the increase in temperature, the soft foam wrapping layer buffers the stress through elastic deformation, preventing the expansion force from being directly transmitted to the first heat insulation strip 31 and the second heat insulation strip 32, and preventing the first heat insulation strip 31 and the second heat insulation strip 32 from warping or detaching due to excessive local stress.

[0038] As a preferred embodiment of this utility model, it may also have the following additional technical features: the cross-section of the heat-insulating rigid block 331 is circular, which can achieve a more uniform stress distribution in a limited space. The stress diffuses evenly along the circumference, reducing local stress concentration and helping to improve the overall stability of the heat-insulating block 33. The cross-section of the heat-insulating soft block 332 is rectangular, which can better fit with the planar contact surfaces of the first heat-insulating strip 31 and the second heat-insulating strip 32, providing a larger contact area, enhancing the friction and adhesion between the heat-insulating soft block 332 and the heat-insulating strip, and improving the reliability of the connection.

[0039] Example 2

[0040] This application also provides an embodiment 2, such as Figure 6As shown, as a modified structure of Embodiment 1, Embodiment 2 differs from Embodiment 1 only in the difference between the above-mentioned heat insulation hard block 331 and heat insulation soft block 332, specifically as follows: the heat insulation hard block 331 has a circular cross section, and the heat insulation soft block 332 has a cross-shaped cross section. The two vertical ends of the heat insulation soft block 332 abut against the first heat insulation strip 31 and the second heat insulation strip 32 respectively, and the two horizontal ends of the heat insulation soft block 332 abut against the first frame 1 and the second frame 2 respectively, achieving all-round fit.

[0041] Example 3

[0042] This application also provides Embodiment 3, such as Figure 7 As shown, as a modified structure of Embodiment 1, Embodiment 3 differs from Embodiment 1 only in the difference between the aforementioned rigid heat-insulating block 331 and flexible heat-insulating block 332, specifically as follows: The flexible heat-insulating block 332 is provided with three layers, and the rigid heat-insulating block 331 is disposed within the three layers of flexible heat-insulating blocks 332 and is perpendicular to the three layers of flexible heat-insulating blocks 332. The three layers of flexible heat-insulating blocks 332 are chemically bonded or physically interlocked to form an interlayer seal. Under high-temperature conditions, when the flexible heat-insulating block 332 expands laterally, the rigid heat-insulating block 331 restricts its excessive deformation through rigid constraints, and the vertical expansion of the flexible heat-insulating block 332 is absorbed by the adjacent layers, avoiding cracking or delamination caused by thermal stress concentration.

[0043] The thermal insulation composite profile in this embodiment has a reasonable structural design and is easy to use. This structure can also be used for other equipment with similar usage requirements. In this embodiment, the thermal insulation composite profile can effectively improve the flexibility of the combination of aluminum profile and thermal insulation strip material while effectively improving the thermal insulation effect of the profile.
