AI Technical Summary
The existing aluminum alloy heat insulation strips have poor versatility under different profile specifications and are not ideal for connection strength, making it difficult to meet the needs of different spacing.
An aluminum alloy heat insulation strip is designed, including a strip-shaped plug-in and a connecting portion perpendicular to the plug-in. Several interphase positioning teeth are provided on the connecting portion, and adapting to different spacings is achieved through these positioning teeth.
Through the design of positioning teeth, the connection strength between the insulation strips is significantly improved, and the spacing between different profiles can be adapted to a certain range, improving versatility.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of heat insulation strips and relates to an aluminum alloy heat insulation strip with good versatility. 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 an aluminum alloy heat insulation strip with good versatility in view of the above problems existing in the prior art. The technical problem to be solved by the utility model is how to improve versatility and connection strength.
[0004] The purpose of the utility model can be achieved through the following technical solutions: an aluminum alloy insulation strip with good versatility, 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 strip-shaped, and both ends of the plug-in portion respectively have a dovetail boss, and the connecting portion has a plurality of positioning teeth arranged alternately, the spacing between adjacent positioning teeth is greater than the thickness of the positioning teeth, and the positioning teeth are located on the side of the connecting portion away from the dovetail boss.
[0005] During installation, two thermal insulation strips form a group, and the two are symmetrically arranged to connect two identical profiles together. The two are symmetrical in that the connecting part faces inward. When the two thermal insulation strips are inserted, one is inserted first, and when the other is inserted, the matching position of the positioning teeth on one of the thermal insulation strips and the positioning teeth on the other thermal insulation strip is selected according to the spacing between the two thermal insulation strips, so that the positioning teeth of one of the thermal insulation strips are inserted into the tooth grooves of the positioning teeth on the other thermal insulation strip. Therefore, this method not only can make the thermal insulation strips have a higher connection strength, but also can select the corresponding positioning tooth position according to the spacing between the two thermal insulation strips, so that it can be adapted within a certain range and has better versatility. BRIEF DESCRIPTION OF THE DRAWINGS
[0006] Figure 1 It is a cross-sectional view of this thermal insulation strip.
[0007] Figure 2 It is a schematic diagram of the connection structure of two insulation strips.
[0008] In the figure, 1, plug-in part; 11, dovetail boss; 2, connecting part; 21, positioning tooth. DETAILED DESCRIPTION
[0009] 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.
[0010] like Figure 1 and Figure 2 As shown, the aluminum alloy thermal insulation strip with good versatility 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 both ends of the plug-in portion 1 have a dovetail boss 11 respectively, and the connecting portion 2 has a plurality of positioning teeth 21 arranged alternately, and the spacing between adjacent positioning teeth 21 is greater than the thickness of the positioning teeth 21, and the positioning teeth 21 are located on the side of the connecting portion 2 away from the dovetail boss 11.
[0011] During installation, two thermal insulation strips form a group, and the two are symmetrically arranged to connect two identical profiles together. The two are symmetrical in that the connecting portion 2 faces inward. When the two thermal insulation strips are inserted, one is inserted first, and when the other is inserted, the matching position of the positioning teeth 21 on one of the thermal insulation strips and the positioning teeth 21 on the other thermal insulation strip is selected according to the spacing between the two thermal insulation strips, so that the positioning teeth 21 of one of the thermal insulation strips are inserted into the tooth groove of the positioning teeth 21 on the other thermal insulation strip. Therefore, this method not only can make the thermal insulation strips have a higher connection strength, but also can select the corresponding positioning tooth 21 position according to the spacing between the two thermal insulation strips, so that it can be adapted within a certain range, and has better versatility.
[0012] 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.
