Description

Technical Field

[0001] The utility model relates to the technical field of aluminum alloy door and window installation, in particular to a novel aluminum alloy door and window connection structure. Background Art

[0002] In aluminum alloy door and window projects, especially the design and construction of door-and-window combinations (such as casement doors and windows from kitchen to balcony), traditional connection structures and methods have many deficiencies and limitations.

[0003] In traditional practice, such as Figure 4 and Figure 5 As shown in the figure, in order to connect the door frame and the window frame, it is necessary to pre-open large and small holes on the door and window frames so that they can be fastened with M5 self-tapping screws. However, this hole-opening method directly weakens the cross-sectional size of the rod, thereby reducing its overall strength and stability. When used for a long time or subjected to external forces, these weak points may become the starting point of damage.

[0004] Large holes on the outside of window frames are usually sealed with decorative buckles, but this approach poses a significant risk of water leakage or seepage. The gap between the decorative buckle and the door and window frames is difficult to completely seal, and especially in windy and rainy weather conditions, moisture can easily penetrate into the room, causing unnecessary losses.

[0005] Decorative buckles are mostly made of PU plastic, which has poor durability and is prone to aging or falling off. In addition, when self-tapping screws are used to fasten and connect the window frame and the corner tube, the window frame and other rods are prone to warping and deformation during the fastening process due to the large screw spacing (usually about 400mm). This deformation not only affects the overall appearance of the doors and windows, but may also increase the risk of water seepage due to the increase in gaps. Utility Model Content

[0006] The utility model aims at the technical problems existing in the prior art and provides a novel aluminum alloy door-window connection structure to solve the problem that the door frame and the window frame need to be connected by opening holes during installation, which reduces the overall strength and stability thereof.

[0007] The technical solution of the utility model for solving the above-mentioned technical problems is as follows: a new type of aluminum alloy door and window connection structure, comprising a main frame, and aluminum alloy window frames, aluminum alloy frame materials and aluminum alloy door frames that are spliced ​​and connected to each other; characterized in that the aluminum alloy window frames, aluminum alloy frame materials and aluminum alloy door frames are respectively clamped with connecting piece one, connecting piece two and connecting piece three on the side close to the main frame; the inner side of the main frame is respectively formed with a fixing part one and a fixing part two that are clamped with connecting piece one and connecting piece three; the connecting piece two is clamped with a fixing piece that abuts against the main frame, and the outer side of the main frame is also equipped with an aluminum alloy pressure plate connected to the fixing piece.

[0008] On the basis of the above technical solution, the present invention can also be improved as follows.

[0009] Furthermore, the aluminum alloy pressing plate is provided with a plurality of fastening screws for tightening the fixing parts.

[0010] Furthermore, the main frame is provided with a telescopic slot adapted to the fixing piece.

[0011] Furthermore, the main frame is provided with limiting grooves along both sides of the telescopic groove opening; and limiting protrusions adapted to the limiting grooves are formed on both sides of the fixing member.

[0012] Furthermore, the inner plate surface of the aluminum alloy pressure plate forms a supporting protrusion that contacts the main frame.

[0013] Furthermore, the aluminum alloy pressure plate has uniformly shaped fixed protrusions on both sides, and an aluminum alloy buckle cover is buckled on the outer side of the aluminum alloy pressure plate through the fixed protrusions.

[0014] Furthermore, the connection positions of the aluminum alloy window frame, the aluminum alloy frame material and the aluminum alloy door frame are all pre-injected with sealant.

[0015] Furthermore, the outer sides of the aluminum alloy window frame, the aluminum alloy frame material and the aluminum alloy door frame are all formed with waterproof retaining edges.

[0016] Moreover, the novel aluminum alloy door and window connection structure provided by the utility model has at least the following beneficial effects compared with the prior art:

[0017] 1. Through the design of connectors 1, 2 and 3, as well as fixing parts 1 and 2 on the main frame, the aluminum alloy window frame, aluminum alloy frame material and aluminum alloy door frame are precisely connected and initially fixed to the main frame. In addition, the introduction of fixings and aluminum alloy pressure plates further enhances the stability of the connection through the tightening effect of the fastening screws, ensuring the stability and safety of doors and windows in long-term use.

[0018] 2. The use of aluminum alloy pressure plates to cover the connection parts not only hides the connection details and improves the overall aesthetics, but also enhances the sealing of the connection through its structural design (such as supporting protrusions), effectively preventing the infiltration of external substances such as rainwater and dust, and improving the waterproof and dustproof performance of doors and windows.

[0019] 3. The expansion slots on the main frame and the limit slots on both sides match the limit protrusions on the fixings, forming an effective adjustment and limit mechanism. This not only facilitates fine-tuning during installation and ensures the accuracy of the connection, but also prevents the fixings from loosening or shifting after installation, ensuring the stability and durability of the connection.

[0027] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0028] It should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrally formed structure. For ordinary technicians in this field, the specific meanings of such terms in this patent can be understood according to specific circumstances.

[0029] like Figure 1 , Figure 2 and Figure 3 As shown, the novel aluminum alloy door-window connection structure of the utility model comprises a main frame 1, and aluminum alloy window frames 2, aluminum alloy frame materials 3 and aluminum alloy door frames 4 which are spliced ​​and connected to each other; the aluminum alloy window frames 2, aluminum alloy frame materials 3 and aluminum alloy door frames 4 are respectively clamped with a connector 1 5, a connector 2 6 and a connector 3 7 on the side close to the main frame 1; a fixing part 1.1 and a fixing part 2 1.2 which are clamped with the connector 1 5 and the connector 3 7 are respectively formed on the inner side of the main frame 1; the connector 2 6 is clamped with a fixing part 8 which abuts against the main frame 1, and an aluminum alloy pressure plate 9 connected with the fixing part 8 is also arranged on the outer side of the main frame 1.

[0030] First, the aluminum alloy window frame 2, the aluminum alloy frame material 3 and the aluminum alloy door frame 4 are precisely connected to the main frame 1 through their respective connectors, connector 1 5, connector 2 6 and connector 3 7. These connectors are respectively designed with structures matching the fixing part 1.1 and fixing part 2 1.2 on the inner side of the main frame, so that they can be easily snapped together during assembly to form a stable preliminary connection.

[0031] For the connection between the aluminum alloy frame material 3 and the main frame 1, a fixing piece 8 is specially used to further enhance the stability. After the fixing piece 8 is clamped with the connecting piece 2 6, it is closely attached to the outer side of the main frame 1. Subsequently, the aluminum alloy pressure plate 9 is installed on the outer side of the main frame 1 and connected to the fixing piece 8 by some means (such as fastening screws) to form a solid external support structure. This design not only strengthens the connection strength between the frame material and the main frame, but also provides additional waterproof and dustproof functions.

[0032] The clamping ensures the initial positioning and stability between the components, while the fastening further enhances the firmness of the connection through external forces (such as the pulling force of the screws). In addition, the covering of the aluminum alloy pressing plate 9 also realizes the hiding and protection of the connection parts, improving the overall aesthetics and durability.

[0033] As an implementation mode, a plurality of fastening screws 10 for tightening the fixing member 8 are installed on the aluminum alloy pressing plate 9 .

[0034] The fastening screws 10 installed on the aluminum alloy pressing plate 9 play a key role in tightening and fixing. These screws pass through the pressing plate 9 and act on the fixing member 8. The tension generated by tightening presses the fixing member 8 tightly against the main frame 1, thereby achieving a firm connection between the aluminum alloy window frame 2, the aluminum alloy frame material 3 and the aluminum alloy door frame 4.

[0035] Specifically, the main frame 1 is provided with a telescopic slot 1.3 adapted to the fixing member 8.

[0036] Specifically, the main frame 1 is further formed with limiting grooves 1.4 along both sides of the telescopic groove 1.3 thereof; and limiting protrusions 8.1 adapted to the limiting grooves 1.4 are formed on both sides of the fixing member 8.

[0037] This design allows a certain amount of adjustment for the fixing member 8 during installation to ensure that it can accurately and tightly contact the main frame 1. At the same time, the limiting grooves 1.4 on both sides of the telescopic groove 1.3 match the limiting protrusions 8.1 on both sides of the fixing member 8, forming an effective limiting mechanism. This limiting design prevents excessive movement or deviation of the fixing member 8 during installation, ensuring the stability and accuracy of the connection.

[0038] As an embodiment, the inner surface of the aluminum alloy pressing plate 9 forms a supporting protrusion 9.1 for contacting the main frame 1. The supporting protrusion 9.1 formed on the inner surface of the aluminum alloy pressing plate 9 is in close contact with the main frame 1, providing additional support for the entire connection structure. This design not only enhances the stability of the connection.

[0039] The aluminum alloy pressing plate 9 has uniformly shaped fixed protrusions 9.2 on both sides, and an aluminum alloy buckle cover 9.3 is buckled on the outer side of the aluminum alloy pressing plate 9 through the fixed protrusions 9.2. The fixed protrusions 9.2 are designed on both side edges of the aluminum alloy pressing plate 9, which not only enhance the overall structural strength of the pressing plate, but also facilitate its connection with the aluminum alloy buckle cover 9.3.

[0040] As an implementation method, the connection positions of the aluminum alloy window frame 2, the aluminum alloy frame material 3 and the aluminum alloy door frame 4 are all pre-injected with sealant. The main function of the sealant is to fill the gaps in the connection parts to ensure the air tightness and water tightness of the connection.

[0041] As an embodiment, the outer edges of the aluminum alloy window frame 2, the aluminum alloy frame material 3 and the aluminum alloy door frame 4 are all formed with waterproof retaining edges 100. The main function of the waterproof retaining edge 100 is to form a physical barrier at the connection between the door and window and the wall or other components to prevent rainwater, moisture and other external moisture from penetrating into the room. This design effectively blocks the path of moisture penetration by increasing the sealing and drainage of the connection, thereby protecting the dryness and comfort of the indoor environment.

[0042] It should be noted that, in this article, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. Unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the utility model can be understood according to the specific circumstances.

[0043] Although the preferred embodiments of the utility model have been described, those skilled in the art may make other changes and modifications to these embodiments once they have learned the basic creative concept. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications falling within the scope of the utility model.
