Description

Technical Field

[0001] This utility model belongs to the field of building door and window technology, specifically an alloy resin integrated flush structure. Background Technology

[0002] In the field of building doors and windows, traditional window frames are often made of a single metal or a single resin material. Although metal window frames have high structural strength, their thermal insulation performance is poor, which can easily cause heat transfer between the indoor and outdoor areas. Resin window frames have good thermal insulation performance, but they have the defect of insufficient rigidity. Moreover, when multi-layer structures or combinations of different materials are used to form window frames, due to limitations such as processing precision and connection methods, there are often obvious step differences on the mating surfaces of each layer, which destroys the flatness of the surface. This not only affects the overall aesthetics of the doors and windows, but also has an adverse effect on sealing, waterproofing and other performance, making it difficult to meet the high requirements for surface flatness of building facades or interior decoration.

[0003] Meanwhile, in existing technologies, the metal and resin layers of window frames are often connected via simple mechanical snap-fits or adhesive bonding, lacking a reliable integrated anchoring structure. This leads to layer separation and loosening during long-term use, further reducing the stability and sealing effect of the window frame structure. Furthermore, traditional window frames struggle to balance strength, thermal insulation, and decorative properties; they either meet rigidity requirements but have poor thermal insulation, or they meet thermal insulation standards but lack rigidity.

[0004] Therefore, an integrated alloy resin flush structure is proposed to address the above problems. Utility Model Content

[0005] To address the problems mentioned in the background art, this utility model provides an integrated alloy resin flush structure that combines the high strength of metal with the excellent thermal insulation performance of resin. It also features a flush surface, strong interlayer connection, good protection and appearance, and scientifically matched thickness to adapt to various scenarios.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an integrated flush alloy resin structure, comprising an alloy resin window frame body, wherein an inner support frame is provided on the inner side of the alloy resin window frame body, and an outer fixing frame is provided on the outer side of the alloy resin window frame body. The alloy resin window frame body is composed of a window frame alloy layer, a window frame connecting layer and a window frame resin layer arranged sequentially from the outside to the inside, and the mating surfaces of the window frame alloy layer, window frame connecting layer and window frame resin layer form a flush structure without step difference.

[0007] Preferably, a first retaining edge is formed outward at the edge of the inner support frame, and a second retaining edge is formed inward at the edge of the outer fixing frame.

[0008] Preferably, the resin layer of the window frame is embedded with resin ribs, and the side of the resin ribs near the window frame connecting layer is provided with serrated alloy anchoring protrusions.

[0009] Preferably, the window frame connecting layer has a protrusion on the side near the window frame alloy layer, and the window frame alloy layer has a groove matching the protrusion on the side near the window frame connecting layer.

[0010] Preferably, the mating surfaces of the window frame alloy layer and the window frame connecting layer, as well as the mating surfaces of the window frame connecting layer and the window frame resin layer, are coated with epoxy structural adhesive.

[0011] Preferably, the surface of the window frame alloy layer is treated with fluorocarbon spraying, and the outer surface of the coating is flush with the edge of the window frame alloy layer.

[0012] Preferably, the thickness of the window frame alloy layer is set to 1.5-2.2 mm, and the thickness of the window frame resin layer is set to 2.0-3.0 mm.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model, through the composite design of alloy layer, connecting layer and resin layer, fully leverages the high strength of metal material and utilizes the excellent thermal insulation performance of resin material, effectively compensating for the shortcomings of traditional single-material window frames in terms of strength or thermal insulation performance, and achieving a balance between strength and thermal insulation performance; at the same time, the flush structure with no step difference at the joint surface of the three not only improves the flatness and aesthetics of the window frame surface, but also optimizes the sealing effect, reduces the possibility of water vapor penetration and dust accumulation, enhances the water tightness and cleanliness of doors and windows, and better meets the surface flatness requirements of building facades and interior decoration; 2. The window frame connecting layer and alloy layer of this utility model adopt a mechanical interlocking method of "protrusion-slot" combined with epoxy structural adhesive bonding. With the synergistic effect of resin ribs and serrated alloy anchor protrusions, the connection between each layer and the overall structure are greatly enhanced, avoiding the problem of separation and loosening between layers during long-term use. This significantly improves the structural stability and service life of the window frame. The design of the outer surface of the fluorocarbon spray coating on the surface of the window frame alloy layer being flush with the edge of the alloy layer not only ensures the protective effect of the spray coating on the alloy substrate, but also enhances the surface flatness and appearance consistency. At the same time, by reasonably setting the thickness of the alloy layer and resin layer, comprehensive performance such as heat insulation is further taken into account while ensuring structural strength.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figures 1 to 6 As shown, this utility model provides an integrated flush structure of alloy resin, including an alloy resin window frame body 1, an inner support frame 2 on the inner side of the alloy resin window frame body 1, and an outer fixing frame 3 on the outer side of the alloy resin window frame body 1. The inner support frame 2 can enhance the stability of the inner structure of the window frame and facilitate the positioning during glass installation. The outer fixing frame 3 can improve the wind pressure resistance of the outer side of the window frame and is suitable for installation and fixing with the wall. The inner support frame 2 and the window frame resin layer 103 are integrally injection molded, and the outer fixing frame 3 and the window frame alloy layer 101 are integrally extruded, which further ensures the connection strength and avoids loosening during later splicing.

[0018] The alloy resin window frame body 1 is composed of a window frame alloy layer 101, a window frame connecting layer 102, and a window frame resin layer 103 arranged sequentially from the outside to the inside. The mating surfaces of the window frame alloy layer 101, window frame connecting layer 102, and window frame resin layer 103 form a flush structure without any step difference. This composite structure not only fully utilizes the high strength and corrosion resistance of the window frame alloy layer 101, but also takes advantage of the excellent thermal insulation performance of the window frame resin layer 103 to make up for the performance shortcomings of traditional single-material window frames. The flush structure without step difference can improve the aesthetics of the window frame surface, reduce dust accumulation, optimize the sealing effect, and reduce the risk of water vapor penetration. In addition, the window frame connecting layer 102 is a nylon PA66 thermal insulation strip, which can further enhance the thermal insulation effect and effectively block the transfer of heat between the indoor and outdoor areas.

[0019] Specifically, a first edge 201 is formed on the outer side of the inner support frame 2, and a second edge 301 is formed on the inner side of the outer fixed frame 3, so as to ensure the limiting and blocking effect without damaging the overall surface flatness of the window frame.

[0020] Furthermore, a resin rib 4 is embedded in the resin layer 103 of the window frame. A serrated alloy anchoring protrusion 5 is provided on the side of the resin rib 4 near the window frame connecting layer 102. The resin rib 4 can significantly enhance the rigidity of the resin layer 103 of the window frame and prevent the resin layer from deforming due to stress after long-term use. The serrated alloy anchoring protrusion 5 can realize the stable anchoring of the resin rib 4 with the window frame connecting layer 102 and the window frame alloy layer 101, and prevent separation between the layers. The resin rib 4 is a glass fiber reinforced resin rib, and the serrated alloy anchoring protrusion 5 is completely embedded in the resin rib 4.

[0021] Furthermore, the window frame connecting layer 102 has a protrusion 6 on the side near the window frame alloy layer 101, and the window frame alloy layer 101 has a slot 7 that matches the protrusion 6 on the side near the window frame connecting layer 102. The engagement of the protrusion 6 and the slot 7 can achieve mechanical fixation between the window frame connecting layer 102 and the window frame alloy layer 101, greatly improving the stability of the interlayer connection.

[0022] It is worth noting that the mating surfaces of the window frame alloy layer 101 and the window frame connecting layer 102, as well as the mating surfaces of the window frame connecting layer 102 and the window frame resin layer 103, are all coated with epoxy structural adhesive. The epoxy structural adhesive can fill the tiny gaps between the mating surfaces of each layer, forming a secondary seal and improving water tightness and air tightness. It can also strengthen the interlayer bonding strength and further prevent the layers from loosening.

[0023] It is worth noting that the surface of the window frame alloy layer 101 is treated with fluorocarbon spraying, and the outer surface of the coating is flush with the edge of the window frame alloy layer 101. The fluorocarbon spraying coating can improve the window frame alloy layer 101's resistance to ultraviolet aging and acid and alkali corrosion, and extend the service life of the window frame. The design of the coating being flush with the edge of the alloy layer further ensures the flatness of the window frame surface and optimizes the consistency of appearance.

[0024] It is worth mentioning that the thickness of the window frame alloy layer 101 is set at 1.5-2.2mm, and the thickness of the window frame resin layer 103 is set at 2.0-3.0mm. This thickness is set to ensure that the window frame alloy layer 101 has sufficient structural strength to resist wind pressure while reducing the overall weight of the window frame. The thickness of the window frame resin layer 103 ensures that the thermal insulation performance meets the standards, thus achieving a balance between strength and thermal insulation effect.

[0025] Working principle and process: The window frame alloy layer 101 provides basic strength for wind pressure resistance and corrosion resistance, and its surface fluorocarbon coating further enhances the protective effect. The window frame connecting layer 102 blocks the transfer of heat between the indoor and outdoor areas. At the same time, it achieves a stable connection with the alloy layer by mechanically engaging with the slot 7 of the window frame alloy layer 101 through the protrusion 6 on one side and bonding with the epoxy structural adhesive on the mating surface. On the other side, it forms an integrated bond with the window frame resin layer 103 through the encapsulation of the resin layer during injection molding and the epoxy structural adhesive. The window frame resin layer 103 plays a role in heat insulation, and the embedded resin ribs 4 enhance its rigidity. The serrated alloy anchor protrusions 5 strengthen the anchoring of the resin ribs 4 with the connecting layer and the alloy layer, preventing separation between the layers. The inner support frame 2 and the outer fixing frame 3 are respectively connected from the inside and outside. To improve overall structural stability, and to ensure surface flatness and reduce sealing risks, the window frame alloy layer 101 is pre-treated and coated with fluorocarbon. A window frame connecting layer 102 with protrusions 6 is prefabricated. When the window frame resin layer 103 is injection molded, resin ribs 4 and serrated alloy anchor protrusions 5 are simultaneously embedded. Then, the protrusions 6 of the window frame connecting layer 102 are inserted into the slots 7 of the window frame alloy layer 101. Epoxy structural adhesive is applied to the mating surfaces of each layer, and the three are composited and cured under pressure. At the same time, an inner support frame 2 with a first baffle 201 and an outer fixing frame 3 with a second baffle 301 are co-extruded or integrally injection molded and connected to the window frame resin layer 103 and alloy layer, respectively. Finally, the flatness of the mating surfaces of each layer is checked, and the overall structure is assembled.
