Description

Technical Field

[0002] The frames of aluminum alloy doors, windows, curtain walls, etc. are formed by connecting profiles end to end, which inevitably lead to corners, such as the right-angled corners of doors and windows. Corners need to be connected and fixed using angle brackets. Traditional angle bracket production mostly adopts extrusion molding or die-casting molding. For the extrusion molding method, it is necessary to mill grooves around the angle bracket body, resulting in high production costs and low production efficiency. A large amount of saw cut waste is also generated in the process. In addition, the dimensional accuracy is difficult to control, and the product quality cannot be guaranteed. For the die-casting method, the molten metal needs to be injected into a metal mold under high pressure. Under high pressure, the molten metal quickly fills the mold cavity and is cooled and solidified in the mold. Due to the high cost of mold manufacturing, the production cost of angle brackets is difficult to control. In addition, when the angle bracket is inserted into two profiles, there is a gap between the angle bracket and the profile, which makes the two profiles easily misaligned, and the flatness of the profile corner needs to be improved.

[0030] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without inventive work.

[0031] refer to Figure 1 and Figure 11 According to a preferred embodiment of the present invention, a corner bracket for assembling corners of a profile includes a pair of corner bracket bodies. The pair of corner bracket bodies are connected to form two corner bracket arms. The two corner bracket arms are respectively inserted into two profiles to achieve precise alignment and splicing of the two profiles at a predetermined angle to each other, ensuring the accuracy of the size and shape of the profile frame. It is understood that the shape and structure of the pair of corner bracket bodies constituting the corner bracket can be the same or different. It is sufficient that the two corner bracket arms can be formed by connecting them. This embodiment does not make specific limitations. Those skilled in the art can set it according to actual needs. As an example, the shape and structure of the pair of corner bracket bodies are exactly the same.

[0032] For ease of understanding and description, Figure 1 and Figure 2 As shown, the two corner code arms are defined as a first corner code arm 101 and a second corner code arm 102, respectively. The first corner code arm 101 and the second corner code arm 102 have a symmetrical structure. Adjacent side surfaces of the first corner code arm 101 and the second corner code arm 102 are adjacent surfaces. The side of the first corner code arm 101 and the second corner code arm 102 facing the angle formed is the inner side surface, the side opposite to the inner side surface is the outer side surface, the side located on one side of the inner side surface and the outer side surface is the first side surface, and the side opposite to the first side surface is the second side surface.

[0033] A first guide groove 103 is provided on the inner side surface at the corner of the first corner code arm 101 and the second corner code arm 102, and a second guide groove 104 is provided on the outer side surface (adjacent surface) at the corner of the first corner code arm 101 and the second corner code arm 102; a third guide groove 105 is provided on one side surface of the adjacent surface of the first corner code arm 101 and the second corner code arm 102, and a fourth guide groove 106 is provided on the other side surface of the adjacent surface of the first corner code arm 101 and the second corner code arm 102. The first guide groove 103, the third guide groove 105, the second guide groove 104 and the fourth guide groove 106 are connected in sequence to form a ring loop.

[0034] After the angle bracket is plugged into the profile and secured, glue can be injected into the second guide groove 104 through the glue injection hole on the profile. Because the first guide groove 103, the second guide groove 104, the third guide groove 105, and the fourth guide groove 106 form a loop, the glue will fill the cavity surrounded by the first guide groove 103, the second guide groove 104, the third guide groove 105, the fourth guide groove 106, and the side wall of the profile. In this way, the multiple guide grooves can effectively increase the area where the angle bracket is connected to the profile through glue, thereby enhancing the connection strength between the angle bracket and the profile. In addition, the first guide groove 103, the second guide groove 104, the third guide groove 105, and the fourth guide groove 106 form an annular glue storage area. While enhancing the connection strength at the corner, it can also seal the gap at the profile corner to prevent water leakage at the profile corner.

[0035] A shaping member 14 is also provided on the first and / or second side surfaces of the first and second angle code arms 101, 102. The shaping member 14 can be manufactured by sheet metal stamping, enabling mass production, greatly improving production efficiency and production costs, and achieving high-precision dimensional control. The shaping member 14 protrudes from the angle code arm and has a contact surface that contacts the inner side surface of the profile. When the first and second angle code arms 101, 102 are respectively inserted into the two profiles, the shaping member 14 on the angle code arm fits against the side wall of the profile, eliminating gaps at the connection between the angle code and the profile, preventing misalignment during assembly of the two profiles, and ensuring the flatness of the corner of the two profiles. The cross-sectional shape of the shaping member 14 is not limited in this embodiment, and can be, for example, a regular or irregular shape such as a circle, an ellipse, or a polygon (regular or irregular). It is understood that the contact surface of the shaping member 14 is preferably flat, so that the shaping member 14 has a larger contact area with the inner side surface of the profile, thereby making the connection structure between the angle bracket and the profile more stable and secure. In addition, the number of shaping members 14 can be one or more. For example, when the overall size of the angle bracket is large, at least two shaping members 14 are provided on the first side surface and / or the second side surface of the first angle bracket arm 101 and the second angle bracket arm 102. When the overall size of the angle bracket is small, only one shaping member 14 can be provided on the first side surface and / or the second side surface of the first angle bracket arm 101 and the second angle bracket arm 102.

[0036] In other embodiments, the above-mentioned shaping member 14 can also be provided on the third guide groove 105 and / or the fourth guide groove 106. The effect of the shaping member 14 provided therein is substantially the same as that provided on the first side surface and / or the second side surface, and will not be described in detail here. It is understood that those skilled in the art can selectively provide the shaping member 14 on the first side surface and / or the second side surface of the first angle code arm 101 and the second angle code arm 102, as well as the third guide groove 105 and / or the fourth guide groove 106, according to actual needs. In addition, it should be noted that since the third guide groove 105 and the fourth guide groove 106 have a certain depth, when the shaping member 14 is provided on the third guide groove 105 and / or the fourth guide groove 106, the shaping member 14 should protrude from the angle code arm by a predetermined distance so that the shaping member 14 on the angle code arm fits the side wall of the profile.

[0037] The corner brackets in this embodiment can be formed from sheet material by stamping and bending, offering numerous advantages, including high production efficiency, low cost, high dimensional accuracy, wide applicability, and excellent surface quality. The corner brackets can be made of metal, such as steel or stainless steel, which offer advantages such as high strength, good toughness, and ease of processing. The corner brackets can be fixedly connected to the profile using fasteners 16 or a ramming method. Both connection methods are described below.

[0038] In some embodiments, after the two corner code bodies are butted together, they are fixedly connected to the profile by fasteners 16. Figures 1 to 8 As shown, the angle code body includes a main body, a first flange 13, a folded edge 12 and a second flange 19 located on the same side of the main body.

[0039] The main body is generally L-shaped, comprising a first connecting edge 11 and a second connecting edge 17 at a predetermined angle. The angle between the first and second connecting edges 11, 17 is the same as the angle between the two profiles, for example, a 90° angle. Guide grooves are formed at the corners of the first and second connecting edges 11, 17. When the two corner brackets are docked, the guide grooves at the corners of the two corner brackets can be defined as a third guide groove 105 and a fourth guide groove 106, respectively.

[0040] The first flange 13 is formed on the periphery of a long side of the first connecting side 11, and can be formed by bending and extending a long side of the first connecting side 11 to one side. The first flange 13 has a short side close to the second connecting side 17, and the short side is bent in the direction close to the second connecting side 17 to form a docking edge 15. When the two corner code bodies are docked, the docking edges 15 of the two corner code bodies are spliced ​​together to form the adjacent surface. A stepped groove can be provided on the docking edge 15 so that the adjacent surface has a "Z"-shaped seam. In this way, on the one hand, it can ensure that the two corner code bodies can be spliced ​​more tightly and accurately to reduce the risk of gaps or unevenness at the seams. On the other hand, the interlocking design of the "Z"-shaped seam also makes the assembly of the corner code easier.

[0041] The folded edge 12 is formed at the other long side of the first connecting edge 11 , and can be formed by bending and extending the other long side of the first connecting edge 11 to one side, and the folded edge 12 is parallel to the first flange 13 .

[0042] The second connecting edge 17 has a first long side proximate to the folded edge 12 and a second long side opposite the first long side. A second flange 19 is formed around the periphery of the first long side and can be formed by bending and extending the first long side to one side. When the two corner code bodies are docked, the second flange 19 of one corner code arm fits against the folded edge 12 of the other corner code arm, and the second flange 19 is located outside the folded edge 12. The short side of the second flange 19 proximate to the first connecting edge 11 is bent to form a bent edge 21. When the two corner code bodies are docked, the bent edges 21 of the two corner code bodies enclose and form a first guide groove 103.

[0043] In some embodiments, to improve the accuracy of the alignment of the two corner code bodies, the two corner code bodies can be joined together by means of a snap fit. For example, a snap fit slot 22 is formed on the first flange 13, and a snap fit 18 is formed on the second long side of the second connecting edge 17. When the two corner code bodies are joined together, the snap fit 18 of the second connecting edge 17 is disposed within the snap fit slot 22 of the first flange 13.

[0044] A fastener mounting member 20 is stamped and formed on each of the first flange 13 and the second flange 19. The fastener mounting member 20 has a predetermined length and a stepped hole formed in the middle. When the two corner code bodies are docked, the fastener mounting member 20 on the first flange 13 of one corner code body and the fastener 16 mounting hole on the second flange 19 of the other corner code body are positioned opposite each other, and a fastener 16 is inserted into the fastener mounting member 20 on both corner code bodies.

[0045] Fastener 16 includes an end 161 and a head 162 extending outward from one side of end 161. End 161 and head 162 of fastener 16 are inserted into the stepped hole of fastener mounting member 20. Riveting head 162 of fastener 16 secures the two angle brackets together, providing excellent durability and convenient installation. Threaded holes 163 extending axially are also defined through end 161 and head 162. After the angle bracket is installed in the profile, the bracket and the profile can be threadedly connected through the threaded holes in fastener 16 and the profile, thereby enhancing the connection strength between the bracket and the profile.

[0046] like Figures 9 to 11 As shown, in some embodiments, after the two corner brackets are docked, the corner brackets are fixedly connected to the profile by ramming. Specifically, ram grooves 26 are provided on the outer surface of the first corner bracket arm 101, away from the corner, and on the outer surface of the second corner bracket arm 102, away from the corner. After the corner bracket is installed in the profile, a ramming machine rams the profile sidewall at the position corresponding to the ram groove 26, causing the corresponding position of the profile sidewall to be recessed into the ram groove 26, thereby fixing the corner bracket and the profile together through the ramming connection.

[0047] The corner code body includes a main body, a first folded edge 18 and a second folded edge 19 located on the same side of the main body.

[0048] The main body is generally L-shaped, comprising a first connecting edge 11 and a second connecting edge 17 at a predetermined angle. The angle between the first and second connecting edges 11, 17 is the same as the angle between the two profiles, for example, a 90° angle. A guide groove is formed at the corner of the first and second connecting edges 11, 17. When the two corner brackets are docked, the guide grooves on the two corner brackets can be defined as a third guide groove 105 and a fourth guide groove 106, respectively.

[0049] The first folded edge 18 is formed at the edge of the outer long side of the first connecting edge 11, and can be formed by bending and extending the edge of the outer long side of the first connecting edge 11 to one side. The first folded edge 18 is close to the corner of the first connecting edge 11 and the second connecting edge 17. The first folded edge 18 is bent to one side to form a docking edge 15. When the two corner code bodies are docked, the docking edges 15 of the two corner code bodies are pieced together to form an adjacent surface. A stepped groove can be provided on the docking edge 15 so that the adjacent surface has a "Z"-shaped seam. The characteristics of the "Z"-shaped seam here have been described in the previous text. In order to save space, they will not be repeated here.

[0050] The second folded edge 19 is formed at the edge of the outer long side of the second connecting edge 17 and can be formed by bending and extending the outer long side of the second connecting edge 17 to one side. The second folded edge 19 is close to the corner of the first connecting edge 11 and the second connecting edge 17. When the two corner code bodies are connected, the second folded edges 19 of the two corner code bodies enclose to form the first guide groove 103.

[0051] A pressure-bearing member 25 is formed on both the first connecting edge 11 and the second connecting edge 17 . The pressure-bearing member 25 has an impact groove 26 . The cross-sectional shape of the pressure-bearing member 25 is not limited in this embodiment, and may be, for example, annular or runway-shaped.

[0052] A reinforcement 23 is also connected between the two angle code bodies. The reinforcement 23 is arranged close to the pressure-bearing part 25. When the angle collision machine hits the side wall of the profile at a position corresponding to the angle collision groove 26, the reinforcement 23 can protect the pressure-bearing part 25 to strengthen the structural strength of the angle code and prevent the pressure-bearing part 25 from breaking due to excessive deformation. The specific shape of the reinforcement 23 is not specifically limited in this embodiment. For example, it can be a columnar structure that has been cut multiple times. The reinforcement 23 has an inclined impact surface 232. When the reinforcement 23 is deformed by force, the outer wall of the pressure-bearing part 25 can be in contact with the impact surface 232, thereby being protected by the reinforcement 23. In addition, the reinforcement 23 also has a limiting edge 231 connected to one side of the impact surface 232. The limiting edge 231 can maintain contact with the end face of the pressure-bearing part 25, thereby achieving the installation and positioning of the reinforcement 23.

[0053] In some embodiments, a positioning protrusion 24 is further formed on the first connecting edge 11 and the second connecting edge 17, and a limiting groove 233 is provided through the reinforcement 23, and the positioning protrusion 24 can be accommodated in the limiting groove 233 of the reinforcement 23. When the two corner code bodies are docked, the positioning protrusion 24 on the first connecting edge 11 of one corner code body and the positioning protrusion 24 on the second connecting edge 17 of the other corner code body are both accommodated in the limiting groove 233 of the reinforcement 23. In this way, the installation of the reinforcement 23 is more convenient, and it is not easy to be displaced when subjected to force, and the structural stability is high. This embodiment does not limit the fixing method of the reinforcement 23 and the corner code body. For example, riveting, welding, etc. can be used. Those skilled in the art can choose a suitable fixing method according to actual needs.

[0054] In summary, the corner brackets in the embodiments of the present invention are assembled from a pair of corner bracket bodies, which can be formed from sheet materials through stamping and bending. This offers advantages such as high production efficiency, low cost, high dimensional accuracy, a wide range of applications, and excellent surface quality. Furthermore, the corner bracket bodies are formed with shaping elements 14, which connect the corner brackets to the profiles through these shaping elements. This ensures that there are no gaps between the corner brackets and the profiles, preventing misalignment between the two profiles during assembly and ensuring a high degree of flatness at the corner of the two profiles.

[0055] It should be noted that the above embodiments can be freely combined as needed. The above are only preferred embodiments of the present invention. It should be noted that those skilled in the art can make several improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should also be considered within the scope of protection of the present invention.
