Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy door and window processing technology, and in particular to an angle-adjustable aluminum alloy door and window glue injection corner bracket. Background Technology

[0002] Conventional doors and windows have a rectangular outline with 90° corners. These corners are typically supported by 90° angled connectors or reinforcements. Currently, in response to client demand, many architects use doors and windows with a rectangular bottom and an arched top to achieve a unique curved style. This creates visually soft, smooth lines and enhances the artistic feel of the living space.

[0003] Specifically, existing external contour door and window structures also have shapes such as a rectangle at the bottom and a triangle, equilateral pentagon, equilateral hexagon, and scalene polygon at the top; the included angle between two adjacent frames is not 90°, which makes the connection method and process of corner nodes complicated and makes it difficult to ensure the smoothness of the connection.

[0004] Traditional construction methods often involve placing galvanized or stainless steel connecting plates at the joints between curved and rectangular frames, securing the outer skin with self-tapping screws. The other three surfaces—the indoor visible surface, the outdoor visible surface, and the glass mounting surface—cannot be connected to any attachments, resulting in insufficient fixing strength. Furthermore, because the ends of the connecting frames have cavities, this connection method makes it difficult to meet standards for corner strength, sealing performance, and appearance quality.

[0005] Furthermore, if the connection is made using a special connector with the same angle as the node, and the angle between the curved frame and the rectangular frame is incorrect due to processing reasons, interference or gaps may occur at the connection point, requiring reprocessing. This not only increases the number of steps in the production process but also results in defects such as unsightly door and window appearance and compromised structural strength. Utility Model Content

[0006] In view of this, the present invention aims to propose an angle-adjustable aluminum alloy door and window glue injection angle bracket, so as to accurately set the angle of the curved frame and the rectangular frame for different shapes, and increase the connection stability between the glue injection angle bracket and the aluminum alloy door and window profile.

[0007] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0008] An adjustable aluminum alloy door and window glue injection angle bracket includes two adjustable angle brackets, fastening bolts for connecting the two angle brackets, locking nuts fitted on the fastening bolts, and positioning screws provided on the angle brackets.

[0009] The angle bracket includes a connected turntable segment and an extension segment. The fastening bolt is located at the center of the turntable segment, and the diameter of the turntable segment is equal to the width of the extension segment.

[0010] The turntable segment is also formed with an arc-shaped notch along its thickness direction. The arc-shaped notch is adapted to the diameter of the turntable segment. The two turntable segments are connected back to back. When the locking nut and the fastening bolt are in a loose state, the two angle brackets can be rotated and adjusted. Along the length direction of the angle brackets, the extension segment is provided with a first adhesive channel.

[0011] Furthermore, a fifth adhesive channel is formed on the side of the turntable segment opposite to the arc-shaped notch. The fifth adhesive channel is arranged radially through the turntable segment. One of the turntable segments of the angle bracket is provided with a stepped hole in the middle to accommodate the fastening bolt, and the other turntable segment of the angle bracket is provided with a hexagonal hole in the middle to accommodate the locking nut. The fifth adhesive channel intersects with the stepped hole and the hexagonal hole respectively.

[0012] Furthermore, the extension segment includes a first connecting segment, a second connecting segment, and an opening segment connected in sequence;

[0013] The first connecting section is connected to the turntable section. The first connecting section is provided with a triangular cavity, the second connecting section is provided with a weight-reducing cavity, and the opening section is provided with a U-shaped cavity that opens outward.

[0014] The arc-shaped notch is formed on the turntable segment and part of the first connecting segment.

[0015] Furthermore, a transition section is provided between the first connecting section and the second connecting section. The transition section is provided with a second adhesive channel that surrounds itself. The transition section is also provided with a third adhesive channel that extends along its thickness direction and a fourth adhesive channel that extends along its width direction. The third adhesive channel and the fourth adhesive channel are intersecting and connected, and both the third adhesive channel and the fourth adhesive channel are connected to the second adhesive channel.

[0016] Furthermore, the first connecting segment also includes a first support plate and a second support plate that are spaced apart;

[0017] One end of the first support plate and the second support plate is provided with a connecting section, and the arc-shaped notch is formed at the other end of the first support plate and the second support plate;

[0018] The first support plate has a first arc-shaped segment, and the second support plate has a second arc-shaped segment;

[0019] The first arc segment and the second arc segment simultaneously abut against the turntable segment.

[0020] Furthermore, the first support plate is formed with a first inclined notch, and when the first inclined notches of the two corner brackets abut against each other, the rotation angle between the two corner brackets is between 61° and 179°.

[0021] Furthermore, the first connecting segment has a second inclined notch formed at one end near the turntable segment, and the second inclined notch of one of the corner codes is arranged opposite to the first inclined notch of the other corner code.

[0022] Compared with the prior art, this utility model has the following advantages:

[0023] The adjustable aluminum alloy door and window glue-injection angle brackets described in this utility model have fastening bolts connected to two angle brackets. When the locking nut and the fastening bolts are in a loose state, the angle of the two angle brackets is adjusted to a predetermined angle, and then locked by the locking nut to fix the angle of the two angle brackets. At the same time, positioning screws are used to fix the two angle brackets again, further preventing relative rotation between the two angle brackets during installation.

[0024] Furthermore, the corner bracket includes an interlocking turntable segment and an extension segment. The turntable segment has an arc-shaped notch, and the turntable segment of one corner bracket is respectively set in the arc-shaped notch of the other corner bracket. During rotation, the arc-shaped notch always abuts against the turntable segment, which can ensure that the two corner brackets rotate stably during rotation and prevent steps or misalignment from appearing in the shape after the two corner brackets are fixed at a fixed angle. This makes the installation of the glued corner brackets smooth, improves the installation efficiency, and also effectively ensures that the door and window structure with the arc frame structure meets the design requirements and improves the manufacturing precision of aluminum alloy doors and windows.

[0045] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0046] This embodiment relates to an adjustable aluminum alloy door and window glue injection corner bracket. Overall, as... Figures 1 to 5 As shown, the glue injection bracket includes two adjustable angle brackets 1, a fastening bolt 2 for connecting the two angle brackets 1, a locking nut fitted onto the fastening bolt 2, and a positioning screw 3 on the angle bracket 1. The angle bracket 1 includes a connected turntable section 101 and an extension section 102. The bolt is located at the center of the turntable section 101, and the diameter of the turntable section 101 is equal to the width of the extension section 102. The turntable section 101 also has an arc-shaped notch 1011 formed along its thickness direction, which is adapted to the diameter of the turntable section 101. The two turntable sections 101 are connected back-to-back. When the locking nut and fastening bolt 2 are in a relaxed state, the two angle brackets 1 can be rotated and adjusted. Along the length direction of the angle bracket 1, the extension section 102 has a first glue channel 5.

[0047] Through the above design, the angle-adjustable aluminum alloy door and window glue-injection angle brackets of this embodiment have fastening bolts 2 connected to two angle brackets 1. When the locking nut and the fastening bolt 2 are in a loose state, the angle of the two angle brackets 1 is adjusted to a predetermined angle, and the locking nut is used to lock the angle of the two angle brackets 1 to fix it. At the same time, positioning screws 3 are used to fix the two angle brackets 1 again, further preventing relative rotation of the two angle brackets 1 during installation.

[0048] Furthermore, the corner bracket 1 includes a connected turntable segment 101 and an extension segment 102. The turntable segment 101 is provided with an arc-shaped notch 1011. The turntable segment 101 of one corner bracket 1 is respectively set in the arc-shaped notch 1011 of the other corner bracket 1. During rotation, the arc-shaped notch 1011 always abuts against the turntable segment 101, which can ensure that the two corner brackets 1 rotate stably during rotation and will not cause steps or misalignment in the shape after the two corner brackets 1 are fixed at an angle. This makes the installation of the glued corner brackets smooth, improves the installation efficiency, and also effectively ensures that the door and window structure with the arc frame structure meets the design requirements and improves the manufacturing precision of aluminum alloy doors and windows.

[0049] Based on the above overall introduction, this embodiment presents an exemplary structure of an angle-adjustable aluminum alloy door and window glue injection angle bracket, such as... Figure 1 and Figure 5 As shown, the two corner brackets 1 are pivotally connected, and their pivot center is the axis of the turntable segment 101. The turntable segment 101 is provided with a circular hole to accommodate the fastening bolt 2. In this embodiment, the fastening bolt 2 is a cross pan head bolt.

[0050] In this embodiment, the first adhesive channel 5 is connected to the fifth adhesive channel 4 and the second adhesive channel 6 described below, forming a three-dimensional adhesive channel system in the length, thickness, and width directions of the adhesive injection corner bracket. This not only facilitates the rapid filling of the adhesive channels with adhesive, but also improves the connection strength between the adhesive injection corner bracket and the door and window frame profiles.

[0051] It should be noted that the positioning screw 3 in this embodiment is a self-tapping screw. The positioning screw 3 is installed on one of the corner brackets 1. The angle of the two corner brackets 1 is determined according to the design angle. The positioning screw 3 is driven into the other corner bracket 1 using an electric drill to achieve double fixation between the two corner brackets 1. This avoids the instability of the door and window frame structure caused by the loosening of the locking nut and fastening bolt 2 due to vibration during the use of the door and window.

[0052] As a preferred embodiment, such as Figure 6 and Figure 7 As shown, a fifth adhesive channel 4 is formed on the side of the turntable segment 101 opposite to the arc-shaped notch 1011. The fifth adhesive channel 4 is arranged radially through the turntable segment 101. A stepped hole 103 for accommodating the fastening bolt 2 is also provided in the middle of the turntable segment 101 of the angle bracket 1. Figure 3 As shown, the turntable section 101 of another segment 1 is provided with a hexagonal hole 104 in the middle to accommodate a locking nut, and the fifth glue channel 4 intersects with the stepped hole 103 and the hexagonal hole 104 respectively.

[0053] In this embodiment, the fifth adhesive channel 4 is disposed on the outer surface of the turntable section 101, such as... Figure 3As shown, when the glue injection corner bracket is inserted into the aluminum alloy door frame profile, the fifth glue channel 4 connects the connection line between the rectangular frame profile and the curved frame profile, and runs from the outer corner to the inner corner. After installation, only a glue injection hole corresponding to the fifth glue channel 4 of one of the corner brackets 1 needs to be set on the profile. The glue can then quickly enter the inner side of the profile from the outside and flow through the gap of the inner corner of the glue injection corner bracket to the fifth glue channel 4 of the other corner bracket 1, and then flow through the outer corner, thus forming a ring-shaped glue channel at the corner of the two profiles. Under the pressure of the corner assembly machine, the two profiles can be tightly connected, improving the connection strength and aesthetics of the rectangular frame and the curved frame.

[0054] In addition, such as Figures 1 to 5 As shown, the extension 102 includes a first connecting section 1021, a second connecting section 1022, and an opening section 1023 connected in sequence. The first connecting section 1021 is connected to the turntable section 101, and a triangular cavity 10211 is provided on the first connecting section 1021. The second connecting section 1022 is provided with a weight-reducing cavity 10221, and the opening section 1023 is provided with a U-shaped cavity 10231 opening outwards. An arc-shaped notch 1011 is formed on the turntable section 101 and part of the first connecting section 1021.

[0055] like Figures 1 to 5 As shown, an opening section 1023 is provided at the end of the angle bracket 1 to facilitate a certain amount of deformation when the angle bracket 1 is inserted into the profile, thereby improving the smoothness of the assembly of the angle bracket 1. In addition, several grooves are provided on the extension section 102 to reduce the contact area between the side of the extension section 102 and the inner cavity of the profile, thereby further reducing friction.

[0056] In addition, by setting a triangular cavity 10211 in the first connecting section 1021 and a weight-reducing cavity 10221 in the second connecting section 1022, the weight of the corner block 1 can be reduced, while also serving as a buffer when the door and window are subjected to external forces.

[0057] like Figures 1 to 8 As shown, a transition section 1024 is provided between the first connecting section 1021 and the second connecting section 1022. The transition section 1024 is provided with a second adhesive channel 6 that surrounds itself. The transition section 1024 is also provided with a third adhesive channel 7 that runs through it in the thickness direction and a fourth adhesive channel 8 that runs through it in the width direction. The third adhesive channel 7 and the fourth adhesive channel 8 are intersecting and connected, and both the third adhesive channel 7 and the fourth adhesive channel 8 are connected to the second adhesive channel 6.

[0058] like Figures 1 to 4 As shown, at the position of the second annular adhesive channel 6, a fourth adhesive channel 8 and a third adhesive channel 7 are respectively provided along the width and thickness directions of the profile, so that there is an annular adhesive channel and a cross-shaped adhesive channel in the middle of the corner bracket 1. This arrangement fills the inside and outside of the corner bracket 1 with adhesive channels at the same time, making the bonding between the corner bracket 1 and the profile more secure.

[0059] Preferably, such as Figures 6 to 7 As shown, the first connecting section 1021 also includes a first support plate 10212 and a second support plate 10213 spaced apart. One end of the first support plate 10212 and the second support plate 10213 has a connecting section 10214, and an arc-shaped notch 1011 is formed at the other end of the first support plate 10212 and the second support plate 10213. The first support plate 10212 has a first arc-shaped segment, and the second support plate 10213 has a second arc-shaped segment. The first arc-shaped segment and the second arc-shaped segment simultaneously abut against the turntable section 101.

[0060] By setting the first arc segment and the second arc segment, a tight fit is formed on the turntable segment 101. During rotation, there will be no shaking due to the gap between the fastening bolt 2 and the round hole on the turntable segment 101. This avoids misalignment of the two corner brackets 1 in the width or thickness direction after fastening, and allows them to be smoothly inserted into the profile. This increases the structural stability of the glued corner bracket and further ensures the accuracy and aesthetics of the connection between the rectangular frame profile and the arc frame profile.

[0061] Preferably, such as Figures 6 to 7 As shown, the extension 102 includes a body and a flange connected to one side of the body. Both the body and the flange are adapted to the cavity shape of the door and window frame profile.

[0062] In addition, such as Figures 4 to 7 As shown, a first inclined notch 10215 is formed on the first support plate 10212, and a second inclined notch 10222 is formed at the end of the first connecting section 1021 near the turntable section 101. The second inclined notch 10222 of one corner bracket 1 is arranged opposite to the first inclined notch 10215 of the other corner bracket 1. By setting the first inclined notch 10215 and the second inclined notch 10222, the angle range when the two corner brackets 1 are adjusted is increased, and the applicability of the glue injection corner bracket is increased.

[0063] Preferably, the rotation angle between the two corner brackets 1 is between 70° and 200°. This setting allows the glued corner bracket to adapt to the design requirements of most door and window structures.

[0064] It should be pointed out that, as Figure 8 As shown, due to the different internal cavity structures of door and window frame profiles, the width and thickness of the corner bracket 1 can be adaptively adjusted to meet the needs of inserting different glue-filled corner brackets in different internal cavities.

[0065] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
