Background technique

The materials used in the production of energy-saving doors and windows include plastic and metal composite materials such as plastic steel, broken bridge aluminum alloy, aluminum-wood composite, aluminum-plastic aluminum, etc. The heat insulation materials used are hard nylon (PA66) and polyvinyl chloride (PVC). It is made by connecting metal materials (aluminum alloy) with this low thermal conductivity material to produce composite profiles for making doors and windows, and then using this composite profile to produce energy-saving doors and windows. This energy-saving door and window can play a positive role in promoting energy saving and emission reduction and improving people's quality of life.

In the production process of the existing heat insulation materials, all adopt the form of whole body hard, and the whole body hard heat insulation strips (C-shaped, I-shaped, multi-cavity shapes) are mechanically occluded into aluminum Alloys or other materials are combined to produce composite materials for the production of energy-saving windows and doors. In the process of producing and processing finished doors and windows of this kind of composite material, sealing materials such as isobaric sealing strips should be embedded in the suitable position of the composite material, so as to achieve windproof, rainproof, heat preservation and other effects. This process is time-consuming and labor-intensive, and if it is not handled well, it will get twice the result with half the effort, and the expected effect will not be achieved. Especially when installing glass on-site for doors and windows, few manufacturers use filling or sealing materials to effectively deal with the gap between the glass edge and the profile, so that It will cause the phenomenon that energy-saving doors and windows are not energy-saving.

Detailed ways

The specific embodiment of the utility model will be described below in conjunction with the accompanying drawings. As shown in Figures 1 to 8: a door and window heat insulation strip, which includes a hard heat insulation strip 1, a flexible heat insulation strip 2 is fixedly arranged on this hard heat insulation strip, and the longitudinal direction of the flexible heat insulation strip here is The geometric figure formed by the section is axisymmetric figure A, the two corners of the top edge of figure A are rounded corners with radius R, the width of A is L1, and the height is H, and the distance between the side of figure A and the horizontal line The included angle is α, the width of the hard heat insulation strip is L, then there are 14mm≤L≤30mm, 0mm＜L1≤30mm, 0mm≤R≤0.5L, 0°≤α≤135°, 0mm＜H≤20mm; The flexible heat insulating strip 2 here can be made into a cavity structure or a solid structure as required;

The two sides of the hard heat insulation strip 1 are connecting parts, and through this connection part, this kind of heat insulation strip is fixedly connected between two frame profiles, or this kind of heat insulation strip is fixedly connected between a frame profile and Between a fan profile;

The above-mentioned connection part has two structural forms. The connection part of one structural form is a convex edge 3, and the longitudinal section of this convex edge 3 is an isosceles trapezoidal shape, and a long groove matching its shape is provided on the profile , insert the protruding edge 3 into the long groove, and this kind of heat insulation strip can be connected to the profile; the connection part of another structural form is the groove 4 set on the hard heat insulation strip, and the profile is A flange matching the groove 4 is provided, and after the flange is plugged into the groove 4, the heat insulation strip can be connected to the profile;

Preferably, the hard heat insulation strip 1 in this technical solution can be made of thermal elastic-plastic body TPV, the flexible heat insulation strip 2 can be made of polyvinyl chloride UPVC, and the hard heat insulation strip 1 and the flexible insulation strip The heat bar 2 forms an integral structure through a soft-hard co-extrusion process.

When the door and window heat insulation strip of this structure is used, the hard heat insulation strip 1 is connected to the frame profile (or fan profile) through the connection parts on both sides, so as to ensure that the flexible heat insulation strip 2 is located inside the profile, as shown in the figure 3 and Figure 4, when this kind of heat insulation strip is fixed between two frame profiles and used as a window frame, the outer layer of the frame profile is provided with ordinary heat insulation strips, while the inner layer is provided with the utility model embodiment When the glass is installed on the frame profile, the bottom edge of the glass will be pressed against the top of the flexible heat insulation strip 2. Since the flexible heat insulation strip 2 is a hollow structure, under the pressure of the glass, the flexible heat insulation Strip 2 undergoes elastic deformation, and the elastic force of flexible heat-insulating strip 2 itself will ensure that it always forms a certain positive pressure on the ground of the glass. to the role of heat insulation;
