Description

Technical Field

[0001] The utility model belongs to the field of door and window manufacturing, and more specifically, relates to a corner fitting for splicing aluminum alloy door and window profiles. Background Art

[0002] In the fields of modern architecture and decoration, aluminum alloy doors and windows are widely used due to their good corrosion resistance, light weight, high strength, and aesthetics. However, during the manufacturing process of aluminum alloy doors and windows, the splicing of profiles is a key link, which directly affects the overall strength, sealing performance, and aesthetics of the doors and windows. Usually, corner fittings are used to connect two adjacent profiles. A corner fitting is a hardware part for reinforcement and connection, and its cross-section is usually L-shaped or V-shaped, with various uses and forms.

[0003] A common corner fitting, such as a waterproof corner fitting installation structure disclosed in the patent document CN205663369U, includes: a window frame, the window frame includes a horizontal window frame and a vertical window frame respectively provided with a horizontal installation hole and a vertical installation hole; an inverted L-shaped corner fitting, including a horizontal side and a vertical side, the horizontal side is inserted into the horizontal installation hole, the vertical side is inserted into the vertical installation hole, and positioning grooves for clamping with the inner walls of the horizontal installation hole and the vertical installation hole are respectively provided on the outer sides of the horizontal side and the vertical side; the corner fitting has a circular arc chamfer, a sealant injection hole is opened at the window frame part opposite to the circular arc chamfer, and a sealant layer is filled in the gap between the circular arc chamfer and the horizontal installation hole and the vertical installation hole.

[0004] When using the above corner fitting, during the installation process, first insert the horizontal side and the vertical side of the corner fitting into the horizontal installation hole and the vertical installation hole respectively, then fit the horizontal window frame and the vertical window frame, and then tap the horizontal window frame downward to make the horizontal window frame move downward. During the downward movement of the horizontal window frame, the inner wall of the horizontal installation hole and the positioning groove on the horizontal side are mutually extruded, and the part of the inner wall of the horizontal installation hole opposite to the positioning groove is embedded into the positioning groove and forms a clamping structure with the positioning groove. However, in actual applications, during the installation process, it is necessary to accurately insert the corner fitting into the installation hole and make the positioning groove and the inner wall of the installation hole be clamped by tapping the window frame. This process may be more cumbersome and requires certain professional skills, increasing the installation difficulty and cost. Summary of the Utility Model

[0005] In order to improve the cumbersome problem of corner fitting installation, the utility model provides a corner fitting for splicing aluminum alloy door and window profiles, and the specific technical solution is as follows:

[0006] An angle code for splicing aluminum alloy door and window profiles, including a first angle code and a second angle code. The first angle code and the second angle code are connected by a locking bolt. The first angle code and the second angle code are spliced into an L shape. The first angle code is used to be inserted into the inner cavity of the first window frame, and the second angle code is inserted into the inner cavity of the second window frame. Through holes for screws to insert are provided on both the first window frame and the second window frame. The screws pass through the through holes and are threadedly connected to the first angle code or the second angle code. Flap pieces for covering the through holes are provided on the outer side walls of the first window frame and the second window frame.

[0007] During installation, first connect the first angle code and the second angle code through the locking bolt and splice them into an L shape. Then insert the first angle code into the first window frame and the second angle code into the second window frame, and use screws to connect the first angle code and the first window frame, and connect the second angle code and the second window frame. Finally, install the flap pieces on the first window frame and the second window frame, and the installation of the angle code can be realized, reducing the installation difficulty and improving the work efficiency.

[0008] In a specific feasible implementation, two L-shaped plates are provided on the back of both the first window frame and the second window frame. The two L-shaped plates are arranged oppositely, and the flap piece is inserted between the two L-shaped plates.

[0009] During installation, by inserting the flap piece between the two L-shaped plates, rainwater can be prevented from seeping into the window frame through the through hole.

[0010] In a specific feasible implementation, notches are provided at the ends of adjacent flap pieces, and two adjacent notches form a V-shaped groove for filling waterproof glue.

[0011] In a specific feasible implementation, an installation cavity is left on the side of the flap piece close to the through hole. The two installation cavities on the back of the first window frame and the second window frame are communicated. A water-swelling waterstop strip is provided in one of the installation cavities, and the other end of the water-swelling waterstop strip is inserted into the installation cavity.

[0012] On the one hand, the water-swelling waterstop strip is used to press the flap piece against the L-shaped plate. On the other hand, when it rains, the water-swelling waterstop strip swells when encountering rainwater, which can effectively prevent rainwater from entering the window frame.

[0013] In a specific feasible implementation, a number of grooves are provided on the first angle code, and convex blocks are provided on the second angle code. The convex blocks and the grooves are in concave-convex fit.

[0014] By using the concave-convex fit of the grooves and the convex blocks, it is convenient for the connecting bolt to pass through the first angle code and the second angle code.

[0015] The beneficial technical effects of the present utility model:

[0016] 1. The locking bolt connection method between the first angle code and the second angle code, as well as the screw connection structure between the angle code and the window frame, greatly simplifies the installation steps. Installers do not need to perform cumbersome knocking operations. They only need to simply insert the angle code into the window frame and fix it with bolts and screws, reducing the requirements for installers' professional skills and improving the installation efficiency;

[0017] 2. The added baffle design effectively blocks the through holes on the window frame, preventing rainwater from seeping into the interior of the window frame through the through holes, and improving the sealing and waterproof performance of the doors and windows. In addition, the cooperation between the baffle and the L-shaped plate, as well as the waterproof glue filled in the V-shaped groove, further enhances the waterproof effect.

[0018] 3. Using the water-swellable waterstop strip, it can automatically expand when rainwater penetrates, closely fit the gap between the baffle and the L-shaped plate, form an effective waterproof barrier, effectively prevent rainwater from entering the window frame, and improve the durability and use safety of the doors and windows.
