Description

Technical Field

[0001] The utility model relates to the technical field related to aluminum alloy windows, in particular to a thermal insulation core aluminum alloy profile. Background Art

[0002] When the traditional thermal insulation strip of the thermally-insulated aluminum alloy profile is combined with the aluminum alloy profile, the insulation strip is simply extended into the glue injection groove at the clamping end of the aluminum alloy, and then glue is injected into the glue injection groove. The insulation strip is connected to the aluminum alloy profile through the glue. This form of connection structure has unsatisfactory connection strength, weak strength in lateral and vertical shear force, and the insulation strip is easy to fall out of the aluminum alloy.

[0003] In the document CN202021901342, an aluminum alloy thermal insulation composite structure is disclosed, including an aluminum inner frame, an aluminum outer frame, and a heat insulation strip. The aluminum inner frame and the aluminum outer frame are both provided with a glue injection groove. The heat insulation strip is located between the aluminum inner frame and the aluminum outer frame. It is characterized in that: a set of relative surfaces of the heat insulation strip are respectively provided with a dovetail structure and a hook structure, the dovetail structure and the hook structure are respectively extended into two glue injection grooves, and a gap is left between the dovetail structure and the corresponding glue injection groove wall, and the hook structure is connected to the corresponding glue injection groove wall. In this structure, the aluminum outer frame and the heat insulation strip have no direct contact points, and are purely connected by the glue in the glue injection groove. After long-term use, it is easy to slip.

[0004] Therefore, a new technical solution is needed to solve the above technical problems. Summary of the invention

[0005] In order to solve the above problems, the utility model discloses a thermal insulation core aluminum alloy profile, which clamps the insulation section through the clamping points of the rolling part, so that the aluminum alloy profile also produces a certain clamping force on the insulation section. The convex points can increase the contact area with the polyurethane glue, increase the lateral and vertical shear force, and improve the overall strength of the profile.

[0006] The technical solution of the utility model is: a thermal insulation core aluminum alloy profile, including an external aluminum alloy profile and an internal aluminum alloy profile, an insulation section is provided between the external aluminum alloy profile and the internal aluminum alloy profile, the insulation section and the external aluminum alloy profile and the internal aluminum alloy profile are combined by glue, the external aluminum alloy profile and the internal aluminum alloy profile are connected by a Y-shaped structure of a rolling part and the insulation section, the rolling part is provided with an outward protrusion and an inward clamping point, and the end of the Y-shaped structure is provided with an outward hooking part.

[0007] By adopting the above technical solution, through the combination of polyurethane glue between the rolling part and the Y-shaped structure, on the one hand, the rolling part plays a clamping role on the Y-shaped structure through the clamping point to prevent the Y-shaped structure from slipping out of the rolling part. At the same time, the rolling part and the clamping point can increase the contact area with the polyurethane glue, thereby improving the connection strength between the Y-shaped structure and the rolling part.

[0008] Preferably, the hook portion is located at the forked end of the Y-shaped structure, the outermost side extension line of the hook portion and the side extension line of the Y-shaped structure are not on the same straight line, and the hook portion is located outside the Y-shaped structure.

[0009] By adopting the above technical solution, the hooking portion can cooperate with the rolling portion. When the rolling portion is squeezed inward by external force, the clamping point of the rolling portion is just clamped on the hooking portion, which plays a clamping role on the Y-shaped structure of the insulation section and prevents the insulation section from slipping.

[0010] Preferably, the Y-shaped structure extends deep into between the rolled parts, and the rolled parts are respectively located on both inner sides of the outer aluminum alloy frame and the inner aluminum alloy.

[0011] By adopting the above technical solution, the sides of the outer aluminum alloy frame and the inner aluminum alloy frame are clamped on the insulation section by the inward extrusion of the two rolling parts, thereby preventing the insulation section from displacement and keeping the bifurcated section of the Y-shaped structure of the insulation section always within the rolling section.

[0012] Preferably, the end of the rolling portion is located at the side depression of the Y-shaped structure, the convex point is located in the middle of the end of the rolling portion, and the clamping point is located on the inner side of the end of the rolling portion, that is, the clamping point is located on the inner side of the convex point, and the clamping point protrudes from the side surface of the rolling portion.

[0013] By adopting the above technical solution, the clamping point is used to prevent the insulation section from slipping and can be clamped. The protrusion can increase the contact area with the polyurethane, thereby increasing the transverse and longitudinal shear force and improving the mechanical properties of the entire profile.

[0014] Preferably, the rolled portion is connected to a side away from the fork-shaped end and the external aluminum alloy profile, and the outer end of the rolled portion is larger than the inner end.

[0015] By adopting the above technical solution, the connecting portion between the Y-shaped structure and the external aluminum alloy profile and the internal aluminum alloy profile can be deformed by rolling, so that the rolling portion can clamp the Y-shaped structure.

[0016] Preferably, the protrusion and the clamping point are both located in the groove on the outer side of the Y-shaped structure, and the glue fills the position between the groove and the rolling part, and the glue is polyurethane.

[0017] By adopting the above technical scheme, polyurethane glue combines the insulation section and the aluminum alloy profile together. The polyurethane profile has good characteristics such as not easy to deform, strong mechanical properties of the profile, insufficient load-bearing capacity of the insulation strip, not easy to penetrate water, and high temperature resistance.

[0018] Preferably, the thermal insulation section is a solid profile.

[0019] The benefits of the utility model are as follows: 1. The utility model can increase the contact area between the protrusions at the end of the rolling part and the polyurethane glue and the Y-shaped structure of the insulation section, thereby improving the transverse shear force and longitudinal shear force of the entire profile and improving the mechanical properties of the entire profile.

[0020] 2. The utility model can clamp and extrude the heat insulation section by deforming the clamping point on the inner side of the rolling part through extrusion, and can fix the heat insulation section to prevent the heat insulation section from being displaced from the rolling part and slipping, thereby improving the overall firmness of the profile.

[0021] 3. The utility model can effectively improve the overall mechanical properties between the aluminum alloy frame and the heat insulation section, and improve the overall strength of the aluminum alloy profile. BRIEF DESCRIPTION OF THE DRAWINGS

The rolled parts 5 are respectively located on the inner sides of the external aluminum alloy frame 1 and the internal aluminum alloy 3. The sides of the external aluminum alloy frame 1 and the internal aluminum alloy frame 3 are clamped by the inward extrusion of the two rolled parts 5 to prevent the insulation section 2 from being displaced, and the bifurcated section of the Y-shaped structure 2-1 of the insulation section 2 is always kept in the rolled section 5.
