Technical Field

[0002] Aluminum-plastic co-extrusion is a composite profile in which aluminum lining and plastic are tightly compounded into one. The profile is made by compounding a foamed plastic with a surface hard core of about 4mm thickness on the surface of the aluminum lining to achieve the combination of inner metal and outer plastic. Aluminum-plastic co-extrusion profile is a commonly used structural form for doors and windows. The design of aluminum-plastic co-extrusion profile can save materials and production energy consumption, so aluminum-plastic co-extrusion profile is an energy-saving profile.
[0003] For example, the utility model with the publication number CN210264339U discloses an aluminum-plastic co-extruded energy-saving profile, including a Lv lining profile, the periphery of the Lv lining profile is wrapped with a layer of foamed plastic profile, and is made in one piece by a set of co-extrusion molds, the bottom of the foamed plastic profile is located at the edge and has two lower grooves, the top of the foamed plastic profile is located at the edge and has two upper grooves, and the bottom of the Lv lining profile is located at the edge and has two dovetail grooves. The aluminum-plastic co-extruded energy-saving profile is provided with a reinforcing frame and a reinforcing vertical rod in the first inner cavity and the second inner cavity respectively, which enhances the strength of the Lv lining profile and is not easy to be destroyed. The dovetail groove and the single-arm structure can make the Lv lining profile and the foamed plastic profile stably connected, and the stability is improved. It is composed of two materials, aluminum and foamed plastic, has strong decorative properties, is simple in manufacturing materials, and is easy to produce and subsequently recycle.
[0004] However, during the installation and use of the aluminum alloy profile, a gap is easily formed between the aluminum alloy profile and the glass due to errors during processing. The existence of the gap reduces the sealing and thermal insulation and sound insulation of the aluminum alloy profile. Therefore, an aluminum-plastic co-extruded energy-saving profile is proposed to address the above problem. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0014] The utility model is provided with foamed plastic, rubber strip and extrusion components. During use, personnel install the glass inside the foamed plastic. Then the relative arrangement of the rubber strip extrusion components will squeeze the glass, so that the sealing strip and the rubber strip are tightly fitted on both sides of the glass, reducing the occurrence of foreign matter entering the interior of the glass, while improving the sealing and thermal insulation and sound insulation of the glass.
