The profile corner bracket used in this application for door and window frames includes a corner bracket body, which includes a first corner bracket support and a second corner bracket support connected to each other. The first and second corner bracket supports are respectively provided with assembly holes. The corner bracket body also has an injection groove. The outer surface of the profile corner bracket has a first guide groove, which connects the injection groove and the assembly hole. The profile corner splicing assembly of this application includes a first profile and a second profile spliced ​​at an angle to each other, and a profile corner bracket installed in the cavities of the first and second profiles. The assembly holes correspond to the assembly openings of the first and second profiles, and they are assembled and fixed by fittings. The first or second profile has an injection port corresponding to the injection groove. The profile corner bracket of this application is injected with glue through the injection groove and the assembly hole.

[0023] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0024] like Figures 1-3As shown, this utility model provides a novel concealed built-in positioning steel plate door and window profile structure, including: a door and window profile body 100, which includes a first profile 1, a second profile 2, and a thermal break strip 3, wherein the thermal break strip 3 is installed between the first profile 1 and the second profile 2. Generally, the first profile 1 and the second profile 2 are both aluminum profiles, thus the door and window profile body 100 constitutes a thermally broken aluminum door and window profile. Furthermore, an assembly bevel angle 4 is provided at the ends of the first profile 1 and the second profile 2. Taking a right-angle door and window as an example, the assembly bevel angle 4 is 45°, so that the two door and window profile bodies 100 are aligned. The two door and window profiles are perpendicularly connected to each other. Specifically, the ends of the first profile 1 and the second profile 2 between the two door and window profile bodies 100 are connected by an inner fastening corner bracket 6, a first positioning steel plate 14, and a second positioning steel plate 23. In this way, the inner fastening corner bracket 6 fixes the two door and window profile bodies 100 together to form the corresponding door and window frames. The first positioning steel plate 14 and the second positioning steel plate 23 are hidden, which further increases the structural strength of the door and window profile bodies 100, provides good waterproof sealing, corrosion resistance, and makes the corner connection of the profiles aesthetically pleasing. At the same time, it improves the strength, tensile strength, and flatness of the interior and exterior surfaces of the door and window corners.

[0025] It is understood that, in addition to the right-angle doors and windows mentioned above, there may also be obtuse-angle windows, acute-angle windows, and other angled window types, which will not be listed one by one in this utility model.

[0026] Furthermore, a first fixing hole 5 is provided on the inner outer wall of the end of the first profile 1 and the second profile 2, and a second fixing hole 60 corresponding to the first fixing hole 5 is provided on the inner fastening corner bracket 6. Therefore, after the inner fastening corner bracket 6 is inserted into the two door and window profile bodies 100, glue can be injected into the door and window profile body 100 through the first fixing hole 5 to seal the inner fastening corner bracket 6 inside the door and window profile body 100. Then, it is connected to the first fixing hole 5 and the second fixing hole 60 through the fastening bolt 51 to further fix the inner fastening corner bracket 6. In this way, the inner fastening corner bracket 6 fixes the two door and window profile bodies 100 together to form the corresponding door and window frame. This utility model provides a first fixing hole 5 on the inner outer wall of the end of the first profile 1 and the second profile 2, and is equipped with an inner fastening corner bracket 6, so that the main body 100 of the door and window profile can resist corrosion, is not limited by processing equipment and site, is easy to produce, is flexible in long-distance and vertical transportation, and is aesthetically pleasing.

[0027] Exemplary first profile

[0028] like Figure 1As shown, in some embodiments of this utility model, a first cavity 11 is provided in the first profile 1 and a second cavity 21 is provided in the second profile 2. When the two door and window profile bodies 100 are vertically connected, an inner fastening corner bracket 6 is inserted between two adjacent first cavities 11 and an inner fastening corner bracket 6 is also inserted between two adjacent second cavities 21. Thus, the inner fastening corner bracket 6 can be accommodated by the first cavity 11 and the second cavity 21, so that the inner fastening corner bracket 6 fixes the door and window profile body 100. It is not limited by processing equipment and site, is convenient to produce, flexible for long-distance and vertical transportation, and has an aesthetically pleasing appearance.

[0029] Exemplary inner fastening corner bracket

[0030] like Figure 1 , Figure 4 As shown, further, some embodiments of this utility model provide a specific structure of the above-mentioned inner fastening corner bracket 6. Here, the inner fastening corner bracket 6 of this structure is L-shaped and has two fixing arms 61. Further, a glue groove 62 is provided on the inner surface of the fixing arm 61, and the above-mentioned second fixing hole 60 is opened in the glue groove 62. In this way, when glue is injected, it can be initially stored in the glue groove 62. Thus, the inner fastening corner bracket 6 can be sealed in the first cavity 11 (second cavity 21), and then connected to the first fixing hole 5 and the second fixing hole 60 by fastening bolts 51 to fix the inner fastening corner bracket 6.

[0031] like Figure 1 , Figure 5 As shown, further, an upwardly extending baffle 12 is provided on the outer side of the first profile 1, and a first hidden cavity 13 is provided on the inner wall of the upper baffle 12. When the two door and window profile bodies 100 are assembled, they can be connected to adjacent first hidden cavities 13 by inserting a first positioning steel plate 14. A second hidden cavity 22 is provided on the inner side of the second cavity 21, and adjacent second hidden cavities 22 are connected by a second positioning steel plate 23. Here, both the first positioning steel plate 14 and the second positioning steel plate 23 are L-shaped. By designing the hidden cavity structure of the first hidden cavity 13 and the second hidden cavity 22, the first positioning steel plate 14 and the second positioning steel plate 23 are also hidden, resulting in good waterproof sealing and aesthetically pleasing corner connections of the profiles. Simultaneously, it improves the strength, tensile strength, and surface flatness of the door and window corners.

[0032] Furthermore, a third hidden cavity (not shown) is provided inside the first cavity 11, and two adjacent third hidden cavities are connected by a third positioning steel plate (not shown), which can further improve the strength of the corners of the doors and windows, tensile strength, and the flatness of the indoor and outdoor surfaces.
