Description

Technical Field

[0001] The utility model belongs to the technical field of door and window installation, and particularly relates to a door and window aluminum profile with an anti - detachment notch structure. Background Technique

[0002] In the field of construction engineering, especially in door and window installation, an installation notch (or door and window notch) refers to a groove structure around the door and window frame. This notch is used to install the sealing strip between the door and window and the wall. The size design of the notch needs to precisely match the sizes of the wall and the door and window frame to ensure that the door and window can be firmly embedded in the wall, and the sealing strip can achieve the effects of waterproofing, wind prevention, heat preservation, and sound insulation. The sealing strip is usually inserted into or extruded into the installation notch of the aluminum profile. However, the sealing strip is prone to deformation under the influence of temperature. On the one hand, the sealing performance of the strip decreases, and on the other hand, the strip will fall off after long - term use. Content of the Utility Model

[0003] The utility model aims to provide a door and window aluminum profile with an anti - detachment notch structure to solve the technical problems that the sealing performance of the strip in the existing installation notch decreases after long - term use and the strip falls off.

[0004] To solve the above - mentioned technical problems, the utility model adopts the following technical solutions:

[0005] A door and window aluminum profile with an anti - detachment notch structure includes an aluminum profile body. The aluminum profile body has an installation notch, and the installation notch has a limiting edge and an anti - detachment edge. The cross - section of the anti - detachment edge is in a hook - like structure.

[0006] A number of notch grooves are arranged on the limiting edge at equal intervals. An elastic positioning member is arranged in each notch groove. The elastic positioning member includes an arc - shaped elastic sheet, a hinge column, and a clamping column. The hinge column and the clamping column are both fixed in the notch groove. One end of the arc - shaped elastic sheet is arranged on the hinge column, and the arc - shaped elastic sheet can rotate around the hinge column. The other end of the arc - shaped elastic sheet is provided with an arc - shaped clamping member. When the arc - shaped clamping member abuts against the clamping column, the arc - shaped elastic sheet is in a contracted and deformed state.

[0007] Furthermore, a number of anti - slip convex points are evenly distributed at the bottom of the installation notch.

[0008] Furthermore, the aluminum profile body has a notch structure, and the bottom of the notch structure has a sunken groove structure.

[0009] Compared with the prior art, the beneficial effects of the present utility model are as follows: In the present utility model, the installation notch is used for installing a sealing strip. The limiting edge and the anti - detachment edge limit the sealing strip within the installation notch. The hook - shaped structure of the anti - detachment edge can hook the sealing strip to prevent the sealing strip from slipping outwards. In addition, several elastic positioning members are provided on the limiting edge of the present utility model. The elastic positioning members press on the sealing strip in the use state, thereby pressing the sealing strip within the installation notch. On the one hand, the tight fit between the sealing strip and the installation notch improves the sealing performance. On the other hand, it avoids the displacement and slipping of the sealing strip after long - term use. The overall structure is reasonably designed and has a good use effect.

[0013] Hereinafter, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0014] The following further describes the present utility model in detail with reference to the embodiments.

[0015] As Figure 1 and Figure 2 shown, a specific embodiment of a door and window aluminum profile with an anti - detachment notch structure provided by the present utility model:

[0016] A door and window aluminum profile with an anti - detachment notch structure includes an aluminum profile body 1. The aluminum profile body 1 has an installation notch 2. The installation notch 2 has a limiting edge 3 and an anti - detachment edge 4. The cross - section of the anti - detachment edge 4 is in a hook - shaped structure;

[0017] A plurality of notched grooves 5 are arranged on the limiting edge 3, and all the notched grooves 5 are arranged at equal intervals. An elastic positioning member is arranged in each notched groove 5, and the elastic positioning member includes an arc-shaped spring piece 6, a hinge column 7 and a locking column 8. The hinge column 7 and the locking column 8 are both fixed in the notched groove 5. One end of the arc-shaped spring piece 6 is arranged on the hinge column 7, and the arc-shaped spring piece 6 can rotate around the hinge column 7. The other end of the arc-shaped spring piece 6 is provided with an arc-shaped clamping member 9. When the arc-shaped clamping member 9 abuts against the locking column 8, the arc-shaped spring piece 6 is in a contracted deformation state.

[0018] When in use, the sealing strip is installed in the installation slot 2, wherein the limiting edge 3 and the anti-slip edge 4 limit the sealing strip in the installation slot 2. Secondly, the hook-shaped structure of the anti-slip edge 4 can hook the sealing strip to prevent the sealing strip from slipping outward. In addition, the limiting edge 3 of this embodiment is also provided with a plurality of elastic positioning parts. In the initial state, the arc-shaped spring piece 6 is located in the notch groove 5 of the limiting edge 3, and the arc-shaped clamping piece 9 at its end does not contact the clamping column 8. After the sealing strip is installed, the arc-shaped spring piece 6 is moved to make the arc-shaped spring piece 6 bend and deform, and the arc-shaped clamping piece 9 abuts against the clamping column 8. At this time, the bent and deformed arc-shaped spring piece 6 applies pressure to the sealing strip, and the pressure application direction is toward the installation slot 2, thereby pressing the sealing strip into the installation slot 2, avoiding the displacement and sliding of the sealing strip after long-term use. Moreover, the close fit between the sealing strip and the installation slot 2 also improves the sealing performance.

[0019] In order to further improve the effect of preventing the sealing strip from slipping, a plurality of anti-skid protrusions 10 are evenly distributed at the bottom of the installation slot 2 , and the anti-skid protrusions 10 can increase the friction between the sealing strip and the installation slot 2 .

[0020] Furthermore, the aluminum profile body 1 has a notch structure 11, and the notch structure 11 is used to install hardware. The bottom of the notch structure 11 has a sinking groove structure 12, and the sinking groove structure 12 can improve the strength and stability of the hardware installation.

[0021] It should be noted that, in this article, terms such as "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0022] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
