Description

Technical Field

[0001] This utility model belongs to the field of corner bracket technology, specifically relating to an aluminum window corner bracket. Background Technology

[0002] With the rapid development of the construction industry, aluminum alloy doors and windows are widely used in various types of buildings due to their advantages such as light weight, corrosion resistance, and beautiful appearance. The structural stability and sealing performance of aluminum windows are particularly crucial in practical use. Corner joints, as a core process in the assembly of door and window frames, directly affect the overall performance and service life of the product. Currently, the traditional aluminum window corner joints widely used in the market still present many technical problems in actual installation and use.

[0003] Low assembly efficiency: Existing corner brackets are generally fixed by multiple screws or clips, which makes the installation process cumbersome, requiring repeated positioning and tightening, which is time-consuming and labor-intensive, making it difficult to meet the needs of large-scale and rapid installation.

[0004] Insufficient sealing: Traditional corner joint structures generally lack dedicated glue injection channels. The sealant must be injected from the external glue injection holes on the aluminum profile. This is not only inconvenient to operate, but also makes it difficult to ensure the uniform distribution of the sealant in the joint gaps. As a result, the sealing effect at the corner joints is poor, which can easily lead to water leakage and affect the performance of doors and windows.

[0005] Weak structural strength: Most existing corner brackets are non-integrated structures, and the connection strength relies on screws, clips or simple plugs. The force is unevenly distributed, and under long-term stress or environmental changes (such as temperature difference and vibration), they are prone to deformation and loosening, which in turn affects the stability and safety of the overall frame.

[0006] Therefore, overcoming the shortcomings of the existing technology is an urgent problem to be solved in this technical field. Utility Model Content

[0013] Furthermore, a profile positioning groove is provided at the lower part between the first connector and the second connector.

Detailed Implementation

[0020] like Figures 1 to 3 As shown, an aluminum window corner bracket includes a corner bracket body 1. One end of the corner bracket body 1 is provided with a first insertion part 10, and the other end of the corner bracket body 1 is provided with a second insertion part 20. The first insertion part 10 and the second insertion part 20 are vertically connected. In use, the first insertion part 10 and the second insertion part 20 are respectively inserted into the cavities of two adjacent frame profiles of the aluminum window frame, thereby firmly connecting the two frame profiles into a right-angle structure and fixing the corner of the aluminum window frame.

[0021] In practical implementation, the surface of the first insertion part 10 is recessed with a first guide adhesive groove 11, and the surface of the second insertion part 20 is recessed with a second guide adhesive groove 21. The first guide adhesive groove 11 and the second guide adhesive groove 21 are vertically connected to form a closed or semi-closed flow channel along the connection area of ​​the corner piece body 1, so as to guide the uniform filling of structural adhesive or sealant. An injection hole 30 is provided between the first guide adhesive groove 11 and the second guide adhesive groove 21. In use, structural adhesive can be injected into the first guide adhesive groove 11 and the second guide adhesive groove 21 through the injection hole 30, so that the structural adhesive extends along the adhesive groove path of the first insertion part 10 and the second insertion part 20, thereby forming a reliable adhesive connection between the insertion part and the profile cavity, improving the shear strength and sealing performance of the corner piece, and effectively preventing loosening and water seepage.

[0022] In practical implementation, the inner surface of the first guide groove 11 is provided with a first spring plate slot 111, and a first reinforcing spring plate 12 with elasticity is provided in the first spring plate slot 111. The size of the first spring plate slot 111 is slightly larger than the size of the first reinforcing spring plate 12, so as to provide elastic deformation space for the first reinforcing spring plate 12. One end of the first reinforcing spring plate 12 is connected to the end of the first spring plate slot 111, and the other end of the first reinforcing spring plate 12 is elastically raised outward. During use, when the first insertion part 10 is inserted into the cavity of the aluminum window profile, the first reinforcing spring plate 12 is pressed and rebounds to fit against the inner wall of the profile, thereby forming an elastic interference fit between the inner wall of the profile and the corner piece, enhancing the stability of the insertion connection, preventing the corner piece from loosening or falling out due to vibration, external force and other factors, and effectively improving the overall connection strength and durability of the corner piece.

[0023] In practical implementation, the inner surface of the second guide groove 21 is provided with a second spring plate slot 211, and a second reinforcing spring plate 22 with elasticity is provided in the second spring plate slot 211. The size of the second spring plate slot 211 is slightly larger than the size of the second reinforcing spring plate 22 in order to provide sufficient elastic deformation space. One end of the second reinforcing spring plate 22 is connected to the end of the second spring plate slot 211, and the other end is elastically raised outward. During the assembly process, when the second insertion part 20 is inserted into the cavity of the aluminum window profile, the second reinforcing spring plate 22 generates a rebound force under compression, and fits against the inner wall surface of the profile, forming a stable elastic interference fit between the inner wall of the profile and the corner piece.

[0024] In practical implementation, a profile positioning groove 40 is provided at the lower part between the first plug-in part 10 and the second plug-in part 20. In use, the profile positioning groove 40 is used to cooperate with the ribs or positioning protrusions on the aluminum window frame profile during the assembly process, further enhancing the positioning reliability and assembly accuracy of the overall structure.

[0025] In practice, the main body 1 of the corner piece is a one-piece molded structure, which can be manufactured by aluminum alloy die casting, extrusion molding, or CNC machining. This structural form can effectively reduce dimensional errors and stress concentration problems caused by splicing multiple parts, and improve the overall mechanical strength and structural stability of the corner piece.

[0026] In summary, one end of the corner piece body 1 is provided with a first insertion part 10, and the other end of the corner piece body 1 is provided with a second insertion part 20. The first insertion part 10 and the second insertion part 20 are perpendicularly connected. The surface of the first insertion part 10 is recessed with a first guide glue groove 11, and the surface of the second insertion part 20 is recessed with a second guide glue groove 21. An injection hole 30 is opened between the first guide glue groove 11 and the second guide glue groove 21. The inner surface of the first guide glue groove 11 is provided with a first... A first spring slot 111 is provided in which a first reinforcing spring 12 with elasticity is provided. A second spring slot 211 is provided on the inner surface of the second guide glue groove 21, and a second reinforcing spring 22 with elasticity is provided in the second spring slot 211. The aluminum window corner piece of this utility model can achieve rapid positioning, high-strength assembly, sealing glue injection, shock resistance and loosening resistance, significantly improving the structural strength and installation efficiency of aluminum window corner pieces, and is suitable for connecting aluminum profiles of various specifications.
