Description

Technical Field

[0001] This invention relates to the field of aluminum alloy technology, and in particular to an aluminum alloy door frame. Background Technology

[0002] Aluminum alloy door frames, due to their relatively low hardness, are easily deformed by impacts if not properly protected during manufacturing and transportation. Deformed frames are difficult to install and affect the sealing performance of doors and windows, leading to air and water leaks. Furthermore, when installing glass in deformed frames, excessive gaps or tight sections can easily cause glass breakage or leaks. In existing aluminum alloy door frames, deformation after a period of use can cause sagging, making it difficult to open and close windows using a pull-out mechanism, thus shortening the lifespan of aluminum alloy doors and windows and causing inconvenience to users.

[0003] The existing aluminum alloy door frames require high standards for their shape during installation, and the window size must be compatible with the door frame. However, due to low construction precision, the dimensions of concrete windows cannot meet the requirements for rectangular windows. For windows with large errors, the gap between the aluminum alloy door frame and the window is uneven after installation, resulting in poor overall window sealing. Sealing is achieved by adding sealant between the door frame and the window. However, the sealant's plasticity decreases after exposure to outdoor sunlight and low winter temperatures. Some sealant may even fall off due to stress caused by changes in the gap between the door frame and the window, leading to a decline in the window's sealing performance and a reduced service life.

[0004] In addition, the sealing strip is a key part to ensure the waterproofing and sound insulation of aluminum alloy doors and windows. If it is not installed properly, it may become loose, fall off or be compressed unevenly, which will result in the failure to guarantee the thermal insulation performance of the doors and windows and thus affect the comfort of living. Summary of the Invention

[0005] In view of this, the present invention aims to provide an aluminum alloy door frame to ensure the overall structural integrity of the door frame, prevent deformation after a period of use, effectively ensure the sealing performance between the aluminum alloy door frame and the window, and improve the service life of the door frame.

[0006] To achieve the above objectives, the technical solution of the present invention is implemented as follows: An aluminum alloy door frame includes an aluminum alloy frame body with an inner hole, and connectors respectively disposed at the corners of the aluminum alloy frame body. The aluminum alloy frame includes four aluminum alloy profiles spliced ​​together, and the connectors are respectively inserted between two adjacent aluminum alloy profiles; The aluminum alloy profile includes a main body, an extension section connected to the end of the main body away from the inner hole, a sealing strip provided on the extension section, the extension section being located on the outside of the window, the inner side of the extension section abutting against the wall, and the side of the main body abutting against the side of the window. The extension is connected to a first glass layer on its outer side, and the sealing strip overlaps between the first glass layer and the wall.

[0007] Furthermore, the main body has a receiving hole formed inside to accommodate the connector. The receiving hole is "L"-shaped, and the connector is adapted to the shape of the receiving hole.

[0008] Furthermore, the connector includes a longitudinal vertical section and an irregularly shaped section connected to one side of the vertical section; The vertical segment includes an open segment, a middle segment, and a tail segment connected in sequence; The irregular segment is connected to the tail segment and part of the middle segment.

[0009] Furthermore, the opening segment has an open mouth at one end, the middle segment and the tail segment are respectively formed with cavities, and the irregular segment has a supporting cavity formed inside.

[0010] Furthermore, the opening segment includes a cross brace, first arcuate segments disposed on both sides of the cross brace, a straight segment connecting one of the first arcuate segments, and a curved segment connecting the other of the first arcuate segments. The opening is formed between the straight segment and the curved segment.

[0011] Furthermore, the intermediate section, and / or the tail section, is provided with a second arched section.

[0012] Furthermore, the irregular segment includes a quadrilateral segment and a protruding segment connected to the quadrilateral segment, with three sides of the irregular segment abutting against the side wall of the main body.

[0013] Furthermore, the protruding section is provided with a third arched section that arches downwards, and the quadrilateral section is provided with a fourth arched section that is opposite to the third arched section.

[0014] Furthermore, the first, second, third, and fourth bow-shaped segments are all provided with mounting parts.

[0015] Furthermore, the extension includes a connecting portion at the end and a straight portion; The connecting part is provided with an opening groove to accommodate one end of the sealing strip, and one end of the sealing strip is inserted into the opening groove; The straight section is provided with a rib, and a groove is formed between the rib and the connecting section. A pad is provided in the groove, and the other end of the pad abuts against the first glass layer.

[0016] Compared with the prior art, the present invention has the following advantages: The aluminum alloy door frame described in this invention strengthens the overall structure of the aluminum alloy frame by inserting connectors at the four corners, and facilitates installation and disassembly. Furthermore, by providing main bodies and extensions on the interlocking aluminum alloy profiles, with the main bodies used to insert the aforementioned connectors, the connectors are first inserted into two adjacent main bodies when splicing two aluminum alloy profiles, facilitating positioning during the connection and installation of the aluminum alloy frame.

[0017] Furthermore, by incorporating an extension section, with its inner side abutting against the wall and its main body side abutting against the window side, a "7"-shaped overlap is formed. This avoids difficulties in positioning the aluminum alloy frame and window due to irregular window shapes, achieving double-sided positioning through this overlap. Additionally, a sealing strip is installed on the extension section. This sealing strip forms a first layer of seal by abutting against the wall and aluminum alloy profile, and then sealant is used to seal the door frame and window, forming a second layer of seal. This improves the installation sealing performance of the aluminum alloy door frame and extends its service life. Attached Figure Description

[0023] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] This embodiment relates to an aluminum alloy door frame, which, overall, is as follows: Figure 1As shown, the aluminum alloy door frame includes an aluminum alloy frame body 1 with an inner hole, and connectors 2 respectively located at the corners of the aluminum alloy frame body 1. The aluminum alloy frame body 1 includes four interconnected aluminum alloy profiles 101, and the connectors 2 are respectively inserted between two adjacent aluminum alloy profiles 101. The aluminum alloy profile 101 includes a main body 1011, an extension section 1012 connected to the end of the main body 1011 away from the inner hole, a sealing strip 3 provided on the extension section 1012, the extension section 1012 is located on the outside of the window 4, the inner side of the extension section 1012 abuts against the wall, and the side of the main body 1011 abuts against the side of the window 4. A first glass layer 5 is connected to the outside of the extension section, and the sealing strip 3 overlaps between the first glass layer 5 and the wall.

[0025] In this embodiment, the aluminum alloy door frame strengthens the overall structure of the aluminum alloy frame 1 by inserting connectors 2 at the four corners of the frame, and facilitates installation and disassembly. Furthermore, by providing a main body 1011 and an extension section 1012 on the interlocking aluminum alloy profiles 101, the main body 1011 is used to insert the aforementioned connectors 2. When splicing two aluminum alloy profiles 101, the connectors 2 are first inserted into two adjacent main bodies 1011, facilitating positioning during the connection and installation of the aluminum alloy frame 1.

[0026] Furthermore, an extension section 1012 is provided, with its inner side abutting against the wall and the side of the main body 1011 abutting against the side of the window 4, forming a 7-shaped overlap. This avoids the difficulty in positioning the aluminum alloy frame 1 and the window 4 due to the irregular shape of the window 4, achieving double-sided positioning through this overlap. Additionally, a sealing strip 3 is installed on the extension section 1012. The sealing strip 3 abuts against the wall and the aluminum alloy profile 101 to form a first layer of seal, and then sealant is used to seal the door frame and the window 4, forming a second layer of seal. This improves the installation sealing performance of the aluminum alloy door frame and extends its service life.

[0027] Based on the above overall description, this embodiment presents an exemplary structure of the aluminum alloy door frame, such as... Figures 1 to 3 As shown, this embodiment of the aluminum alloy door frame is illustrated using a rectangular door or window as an example. For irregularly shaped doors or windows, the angle of the connector 2 can be adjusted. The connector 2 is prefabricated in the factory and is suitable for applications such as... Figure 3 and Figure 4 The aluminum alloy profile 101 is used for the main body 1011.

[0028] As a preferred embodiment, such as Figure 3 As shown, the main body 1011 has a receiving hole 10111 formed inside to accommodate the connector 2. The receiving hole 10111 is L-shaped, and the shape of the connector 2 is adapted to the receiving hole 10111. It should be noted that... Figure 3The aluminum alloy profile 101 has a step on its main body 1011 for use with double-glazed windows. For single-glazed aluminum alloy profile 101, refer to... Figure 4 ,exist Figure 4 The structure of the middle connector 2 remains unchanged. It can be fixedly inserted into the main body 1011 through the abutment of the two sides and the top and bottom.

[0029] Furthermore, such as Figure 3 As shown, the connector 2 includes a vertical section 201 and an irregularly shaped section 202 connected to one side of the vertical section 201. The vertical section 201 includes an open section 2011, a middle section 2012, and a tail section 2013 connected in sequence. The irregularly shaped section 202 is connected to the tail section 2013 and part of the middle section 2012. The vertical section 201 allows the connector 2 to abut against the main body 1011 in the longitudinal direction of the receiving hole 10111, thus limiting the longitudinal displacement of the connector 2. The combined action of the irregularly shaped section 202 and the vertical section 201 restricts the lateral movement of the connector, further improving the connection stability of the connector 2 and thus strengthening the overall strength of the door frame.

[0030] Furthermore, such as Figure 3 and Figure 4 As shown, the opening segment 2011 has an opening mouth 20111 at one end, the middle segment 2012 and the tail segment 2013 are respectively formed with cavities 20121, and the irregular segment 202 has a supporting cavity 2021 formed inside. By setting the opening mouth 20111, the deformation of the opening mouth 20111 can be facilitated, and the connection between the connector 2 and the receiving hole 10111 can be facilitated.

[0031] And, as Figure 3 and Figure 4 As shown, the opening section 2011 includes a cross brace 20112, first arched sections 20113 on both sides of the cross brace 20112, a straight section 20114 connecting one of the first arched sections 20113, and a curved section 20115 connecting the other first arched section 20113. An opening is formed between the straight section 20114 and the curved section 20115. The curved section 20115 and the first arched section 20113 further ensure the smoothness of the connector 2 during insertion, preventing jamming. Furthermore, this design ensures that the connector 2 fills the receiving hole 10111, guaranteeing the structural strength of the door frame corners and preventing deformation of the middle receiving hole 10111 over time, thus improving the lifespan of the aluminum alloy door frame.

[0032] Preferably, such as Figure 3As shown, the middle section 2012 and the tail section 2013 are provided with a second arc-shaped section 203. In other embodiments, the second arc-shaped section 203 may also be provided in the middle section 2012, or the second arc-shaped section 203 may be provided in both the middle section 2012 and the tail section 2013, to further increase the lateral and longitudinal adjustment of the connector 2 within the receiving hole 10111, facilitating installation.

[0033] Preferably, such as Figure 3 and Figure 4 As shown, the irregular segment 202 includes a quadrilateral segment 2022 and a protruding segment 2023 connected to the quadrilateral segment 2022. Three sides of the irregular segment 202 abut against the side wall of the main body 1011, increasing the lateral and longitudinal adjustment of the connector 2 within the receiving hole 10111, which facilitates installation.

[0034] In addition, such as Figure 3 As shown, the protruding section 2023 is provided with a downwardly arched third bow-shaped section 204, and the quadrilateral section 2022 is provided with a fourth bow-shaped section 205 opposite to the third bow-shaped section 204, which increases the lateral and longitudinal adjustment of the connector 2 in the receiving hole 10111, making it easier to install.

[0035] Preferably, such as Figure 5 and Figure 6 As shown, mounting portions 206 are provided on the first arc-shaped segment 20113, the second arc-shaped segment 203, the third arc-shaped segment 204, and the fourth arc-shaped segment 205. In this embodiment, the mounting portions 206 are formed into multiple threaded holes or round holes, and the connector 2 is fixed to the aluminum alloy profile 101 by screws or rivets. Of course, it is also possible to inject curing adhesive into each of the above-mentioned arc-shaped segments for fixation.

[0036] Preferably, such as Figure 3 and Figure 4 As shown, the extension 1012 includes a connecting portion 1013 at one end and a straight portion 1014. The connecting portion 1013 has an opening groove 1015 for receiving one end of the sealing strip 3, and one end of the sealing strip 3 is inserted into the opening groove 1015. The straight portion 1014 has a raised rib 1016, and a groove is formed between the raised rib 1016 and the connecting portion 1013. A pad 1017 is provided in the groove, and the other end of the pad 1017 abuts against the first glass layer 5. This arrangement not only facilitates the installation of the sealing strip 3, but the extension also provides an installation position for the sealing strip 3, improving the sealing performance. Furthermore, the pad 1017 ensures the accuracy of the connection position between the first glass layer 5 and the door frame, guaranteeing the flatness of the first glass layer 5.

[0037] As Figure 1 and Figure 2As shown in the figure, the door frame shown can be an integral outer frame or a separate aluminum alloy frame 1. For sliding windows or sliding doors, the aluminum alloy profile 101 can be adapted, which is not shown in this figure.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
