Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of heat insulation strips and relates to a high-strength aluminum alloy heat insulation strip. Background Art
[0002] Aluminum alloy doors and windows that achieve heat insulation effect by bridging aluminum alloy profiles with heat insulation strips to achieve metal isolation are commonly known as thermal insulation aluminum. The heat insulation strips are generally made of PA66 material, which has a certain hardness and also needs to play a certain supporting and connecting role in the combined profile. The insertion position of the heat insulation strip is generally in the shape of a dovetail boss, which is compatible with the dovetail groove on the profile. The heat insulation strip is inserted into the profile. Two heat insulation strips are generally symmetrically inserted between the two profiles. In order to improve versatility (different profile specifications require different spacing between the two heat insulation strips), the two heat insulation strips are generally not connected separately, which makes the strength of the heat insulation strip as a supporting connection not ideal. Utility Model Content
[0003] The purpose of the utility model is to provide a high-strength aluminum alloy heat insulation strip in view of the above-mentioned problems existing in the prior art. The technical problem to be solved by the utility model is how to improve the versatility and connection strength.
[0004] The purpose of the utility model can be achieved through the following technical solutions: a high-strength aluminum alloy thermal insulation strip, characterized in that it includes a strip-shaped plug-in portion and a connecting portion perpendicular to the plug-in portion, the connecting portion is in the shape of a strip, and both ends of the plug-in portion respectively have a dovetail boss, one end of the plug-in portion is connected to a position deviated from the midpoint of the plug-in portion, and the other end of the connecting portion has a limiting flange perpendicular to the connecting portion, and the limiting flange is located on the side of the connecting portion away from the dovetail boss.
[0005] During installation, two thermal insulation strips form a group, which are symmetrically arranged and jointly connect two identical profiles. The two are symmetrical in that the connecting parts face inwards. After the two thermal insulation strips are installed, a rectangular area is formed between the two connecting parts and the two limiting flanges. Insert strips made of metal or polymer materials can be inserted into the area to establish a connection between the two thermal insulation strips. Specifically, the two are in a tensioned state to prevent the thermal insulation strips from loosening in the profile. This method not only has a greater connection strength, but also allows the selection of insert strips of corresponding sizes according to different profiles, thereby improving the versatility of the thermal insulation strips. In addition, this method is also relatively easy for the installation of the thermal insulation strips. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
[0011] like Figure 1-Figure 3 As shown, the high-strength aluminum alloy thermal insulation strip includes a strip-shaped plug-in portion 1 and a connecting portion 2 perpendicular to the plug-in portion 1. The connecting portion 2 is strip-shaped, and each end of the plug-in portion 1 has a dovetail boss 11. One end of the plug-in portion 1 is connected to a position deviated from the midpoint of the plug-in portion 1, and the other end of the connecting portion 2 has a limiting flange 21 perpendicular to the connecting portion 2. The limiting flange 21 is located on the side of the connecting portion 2 away from the dovetail boss 11.
[0012] During installation, two thermal insulation strips form a group, and the two are symmetrically arranged to connect two identical profiles. The two are symmetrical in that the connecting portion 2 faces inward. After the two thermal insulation strips are installed, a rectangular area is formed between the two connecting portions 2 and the two limiting flanges 21. A metal or polymer material insert 3 can be inserted into the area to establish a connection between the two thermal insulation strips. Specifically, the two are in a tensioned state to prevent the thermal insulation strip from loosening in the profile. This method not only has a greater connection strength, but also allows the insert 3 of corresponding size to be selected according to different profiles, thereby improving the versatility of the thermal insulation strip. In addition, this method is also relatively easy for the installation of the thermal insulation strip.
[0013] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
