[0002] Thermally insulated aluminum profiles refer to aluminum profiles that incorporate thermal insulation materials between their inner and outer layers to effectively prevent heat conduction from the external environment, thereby improving their thermal insulation performance and reducing thermal bridging. Thermally insulated aluminum profiles typically consist of an outer aluminum alloy layer, an inner aluminum alloy layer, and thermal insulation strips; currently, the common practice is to manufacture each component separately according to usage requirements and then assemble them.

[0003] In the prior art, such as Chinese utility model patent with publication number CN209353961U, published on September 6, 2019, an aluminum profile for doors and windows is disclosed. It uses four independent aluminum profiles and then divides the aluminum profile into inner and outer parts by thermal break strips. The inner aluminum profile and the outer aluminum profile are connected by thermal break strips.

[0004] However, the inventors discovered that the connection strength of the above-mentioned splicing method using heat insulation strips is difficult to guarantee. Utility Model Content

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0033] like Figures 1 to 7 The spliced ​​insulated aluminum profile shown includes: an outer profile 1, which is arranged in an L-shape and includes a vertical profile 11 and a horizontal profile 12 with one end perpendicularly connected to the end of the vertical profile 11. The inner wall of the free end of the vertical profile 11 has a first snap-fit ​​portion 11a, and the inner wall of the free end of the horizontal profile 12 has a second snap-fit ​​portion 12a. An inner profile 2 is located diagonally opposite the extension lines of the first snap-fit ​​portion 11a and the second snap-fit ​​portion 12a. The inner profile 2 has a third snap-fit ​​portion 21 corresponding to the first snap-fit ​​portion 11a and a fourth snap-fit ​​portion 22 corresponding to the second snap-fit ​​portion 12a. Figures 1 to 3 As shown, the outer wall of the horizontal profile 12 has two vertically recessed splicing grooves 12b, the vertical profile 11 has a first retaining arm 13, and the inner profile 2 has a second retaining arm 23. Both the first retaining arm 13 and the second retaining arm 23 are adapted to the shape of the splicing grooves 12b, and both extend in a direction away from the horizontal profile 12. Figure 1 As shown, the heat insulation assembly includes a first heat insulation strip 31 connected at both ends to a first snap-fit ​​portion 11a and a third snap-fit ​​portion 21, and a second heat insulation strip 32 connected at both ends to a second snap-fit ​​portion 12a and a fourth snap-fit ​​portion 22, respectively.

[0034] In the above embodiments, the present invention installs the first heat insulation strip 31 through the first snap-fit ​​part 11a and the third snap-fit ​​part 21, and installs the second heat insulation strip 32 through the second snap-fit ​​part 12a and the fourth snap-fit ​​part 22, and provides splicing grooves 12b that are compatible with both the first snap-fit ​​arm 13 and the second snap-fit ​​arm 23, making the installation quick and convenient; compared with the prior art, the reliability of the splicing connection of the heat-insulating aluminum profile is improved.

[0035] In this embodiment of the invention, the outer profile 1 and the inner profile 2 are made of aluminum alloy, and the thermal insulation component is made of PVC. The aluminum alloy provides the outer profile 1 and the inner profile 2 with superior rigidity and resistance to deformation. PVC has good thermal insulation properties and is easy to process. This material selection creates a complementary function, and the materials can be recycled and reused after their service life, resulting in environmental benefits.

[0036] Based on the above embodiments, in order to make the installation of the thermal insulation strip more stable, such as Figure 4 As shown, the first thermal insulation strip 31 and the second thermal insulation strip 32 are arranged in a straight line, and both ends of the first thermal insulation strip 31 and the second thermal insulation strip 32 are dovetail-shaped. The straight line arrangement facilitates the interlocking between the thermal insulation strip, the outer profile 1, and the inner profile 2, while ensuring uniform stress on the thermal insulation strip during connection, thus improving the stability of the thermal insulation system. It should be noted that the dovetail-shaped structure means that the end of the thermal insulation strip is shaped like a dovetail, which is an outwardly expanding wedge-shaped structure. The dovetail design can enhance the interlocking strength and prevent the first thermal insulation strip 31 and the second thermal insulation strip 32 from loosening or falling off when subjected to external forces.

[0037] In this embodiment of the utility model, when the products are connected to each other, such as Figure 1 As shown, the splicing groove 12b has a serrated structure, and both the first clamping arm 13 and the second clamping arm 23 have protrusions that match the serrated structure. The serrated structure and the protrusions improve the overall strength of the splicing of this product, while preventing the ingress of air or moisture.

[0038] To further ensure the stability of the thermal insulation strip installation, such as Figure 5As shown, the second locking portion 12a includes an inner first locking portion 12a1 and an outer second locking portion 12a2. The first locking portion 12a1 and the second locking portion 12a2 are arranged opposite to each other, forming a dovetail-shaped groove for locking one end of the first heat insulation strip 31. One of the two splicing grooves 12b is close to the free end of the horizontal profile 12, and the sidewall of the splicing groove 12b near the free end is coplanar with the second locking portion 12a2. It should be noted that the inner and outer sides of the second locking portion 12a are relative to the center of the outer profile 1; the closer to the center, the inner side, and the farther away, the outer side. The dovetail-shaped groove can firmly fix the dovetail-shaped end of the first heat insulation strip 31, forming a reliable mechanical lock. The coplanar splicing grooves 12b allow for a smooth transition of the overall structure when the product is spliced, and during the splicing process, the second locking portion 12a2 is squeezed, further squeezing and fixing the first heat insulation strip 31. This product enables the secure installation of thermal insulation strips and also provides greater flexibility for splicing functions.

[0039] Furthermore, in the embodiments of this utility model, please continue to refer to... Figure 5 The first locking portion 11a includes a first locking claw 11a1 and a second locking claw 11a2 that are oppositely arranged and form a dovetail-shaped groove. The second locking claw 11a2 is located at the end of the vertical profile 11 near its free end, and the free end of the second locking claw 11a2 is perpendicularly connected to the first locking arm 13. A dovetail-shaped groove is formed between the first locking claw 11a1 and the second locking claw 11a2. The structure of the dovetail-shaped groove is the same as described above and will not be repeated here. The perpendicular connection between the free end of the second locking claw 11a2 and the first locking arm 13 helps to strengthen the force-bearing capacity of the locking point and prevents the locking part from loosening due to uneven force during long-term use. This arrangement optimizes the force distribution of the overall structure and improves the thermal insulation performance and durability of the system.

[0040] In embodiments of this utility model, the arrangement of the inner profile 2 is as follows: Figure 6 As shown, the inner profile 2 includes an arc-shaped support arm 20, and a first retaining claw 21a and a second retaining claw 22a respectively connected to the outer wall of the arc-shaped support arm 20. The first retaining claw 21a and the arc-shaped support arm 20 form a third engaging portion 21, and the second retaining claw 22a and the arc-shaped support arm 20 form a fourth engaging portion 22. The arc-shaped support arm 20 helps to evenly distribute the force and avoid excessive local force that could lead to structural deformation. The third engaging portion 21 is formed by the first retaining claw 21a and the arc-shaped support arm 20, and the fourth engaging portion 22 is formed by the second retaining claw 22a and the arc-shaped support arm 20. Both are used to connect with the thermal insulation strip, enhancing the firmness of the engagement.

[0041] In the embodiment of the present utility model, as Figure 2 and Figure 6As shown, the free end of the first clamping claw 21a is tilted upwards in a direction away from the arc-shaped support arm 20. It should be noted that this tilting upwards means that the direction of the free end is no longer parallel to or parallel to the outer wall of the arc-shaped support arm 20, but rather tilted away from the arc-shaped support arm 20, forming an inclined angle. The tilting angle may be small or large, depending on the actual usage requirements. The tilting of the free end is to create a locking effect during clamping, such as during splicing... Figure 2 As shown, the raised free end can be further compressed by the second heat insulation strip 32 after being squeezed, thus enhancing stability.

[0042] Furthermore, in the embodiments of this utility model, in order to further enhance the stability of the profile, reference is continued... Figure 2 and Figure 6 The second clamping arm 23 is vertically connected to the second clamping claw 22a. A vertical connection means that the connection surfaces of the second clamping arm 23 and the second clamping claw 22a are at a 90-degree angle. Vertical connections offer better shear resistance, effectively reducing damage or failure at the connection point. Vertical connections also allow for compression of the first thermal insulation strip 31 during assembly.

[0043] In embodiments of this utility model, to achieve diversity in splicing methods, such as... Figure 7 As shown, the vertical profile 11 has slots 11b with the same spacing as the splicing grooves 12b. The spacing of the slots 11b is consistent with the spacing of the splicing grooves 12b, enabling splicing of the product in multiple directions. During profile splicing, after the first clamping arm 13 and the second clamping arm 23 are inserted into the splicing grooves 12b, a slot 11b is also provided in another direction to facilitate further splicing of the profiles, improving the wide applicability of this product.

[0044] Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
