Description

Technical Field

[0001] The utility model relates to the technical field of building doors and windows, especially the external assembly structure of a composite material window frame. Background Art

[0002] A composite material window frame is a new type of window frame structure composed of multiple materials, usually combining the advantages of metals, plastics, glass fiber reinforced plastics or other high-performance composite materials. This window frame design aims to integrate the characteristics of different materials to achieve higher strength, better heat insulation performance, lighter weight and longer service life.

[0003] The assembly of traditional window frames usually needs to be completed in the factory. The integral window frame is already assembled when leaving the factory. This traditional method has many inconveniences. Especially in the transportation link, due to the large size of the window frame, the integral window frame occupies a large space during transportation, resulting in a significant increase in transportation costs. At the same time, the integral window frame is prone to collision and extrusion during transportation, increasing the risk of window frame deformation or damage. Especially in long-distance transportation or under poor road conditions, this risk is more prominent. Content of the Utility Model

[0004] To solve the above technical problems, the utility model provides an external assembly structure of a composite material window frame.

[0005] The utility model is realized by the following technical solutions: The external assembly structure of a composite material window frame includes an outer frame. An angle code embedding cavity is opened inside the outer frame. An aluminum alloy angle code one is fixedly installed inside the angle code embedding cavity. Several flexible rubber blocks are fixedly connected to the surface of the aluminum alloy angle code one. A friction cushion layer is arranged on one side of the surface of the flexible rubber block. An aluminum alloy angle code two is fixedly installed on the surface of the aluminum alloy angle code one. An angle code installation hole is opened on the surface of the outer frame. A self-tapping screw is fixedly installed inside the angle code installation hole.

[0006] Through the above technical solutions, by arranging a friction cushion layer made of high-density polyethylene on one side of the surface of the flexible rubber block, during the installation process, when the aluminum alloy angle code one and the aluminum alloy angle code two show an unstable trend and tend to move in the reverse direction and disengage, the friction cushion layer on the other side of the flexible rubber block will contact the inner wall of the angle code embedding cavity, generating frictional resistance, thereby effectively preventing the angle code from disengaging from the angle code embedding cavity and avoiding the problem of window frame deformation or damage caused by angle code loosening. On the other hand, splitting the angle code into two sections and designing it in a form that can be assembled on-site enables the window frame to be disassembled into smaller components during transportation, greatly reducing the transportation volume and cost, while reducing the damage risk during transportation, facilitating transportation and on-site installation, and improving the overall construction efficiency.

[0007] As a further improvement of the above solution, two corner code embedding cavities are provided, and the two corner code embedding cavities are respectively provided on both sides inside the outer frame.

[0008] Through the above technical solution, corner code embedding cavities are provided on both sides, making the assembly of the window frame more stable and the force more uniform, further enhancing the overall structural strength and stability of the window frame.

[0009] As a further improvement of the above solution, the material of the friction cushion layer is high-density polyethylene.

[0010] Through the above technical solution, the friction cushion layer made of high-density polyethylene has high wear resistance and friction coefficient, can effectively improve the friction force between the corner code and the corner code embedding cavity, further enhance the stability after installation, and extend the service life of the window frame.

[0011] As a further improvement of the above solution, the corner code embedding cavity is adapted to aluminum alloy corner code one and aluminum alloy corner code two.

[0012] As a further improvement of the above solution, both the aluminum alloy corner code one and the aluminum alloy corner code two are fixedly installed on the outer frame through self-tapping screws.

[0013] Through the above technical solution, using self-tapping screws for fixation, the installation operation is simple and fast, the connection is firm and reliable, can effectively ensure the tight combination of the aluminum alloy corner code one and the aluminum alloy corner code two with the outer frame, and improve the overall structural stability of the window frame.

[0014] As a further improvement of the above solution, the number of the aluminum alloy corner code one and the aluminum alloy corner code two is two, and the two aluminum alloy corner code one and the aluminum alloy corner code two are respectively fixedly installed inside the corner code embedding cavity.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] In the present utility model, a friction cushion layer made of high-density polyethylene is provided on one side of the surface of the flexible rubber block. During the installation process, when the aluminum alloy corner code one and the aluminum alloy corner code two show an unstable tendency and want to move in the reverse direction and disengage, the friction cushion layer on the other side of the flexible rubber block will contact the inner wall of the corner code embedding cavity, generating frictional resistance, thereby effectively preventing the corner code from disengaging from the corner code embedding cavity, avoiding the problem of window frame deformation or damage caused by corner code loosening. On the other hand, splitting the corner code into two sections and designing it in a form that can be assembled on-site makes the window frame can be disassembled into smaller components during transportation, greatly reducing the transportation volume and cost, and at the same time reducing the damage risk during transportation, facilitating transportation and on-site installation, and improving the overall construction efficiency.

[0023] Next, in combination with the drawings and specific implementation modes, the present utility model will be further described. It should be noted that on the premise of no conflict, the following described embodiments or technical features can be combined arbitrarily to form new embodiments.

[0024] Embodiment:

[0025] Please refer to Figures 1-4 , the external assembly structure of the composite material window frame in this embodiment includes an outer frame 1. A corner code embedding cavity 2 is opened inside the outer frame 1. A first aluminum alloy corner code 3 is fixedly installed inside the corner code embedding cavity 2. Several flexible rubber blocks 4 are fixedly connected to the surface of the first aluminum alloy corner code 3. A friction cushion layer 5 is arranged on one side of the surface of the flexible rubber block 4. A second aluminum alloy corner code 6 is fixedly installed on the surface of the first aluminum alloy corner code 3. A corner code installation hole 7 is opened on the surface of the outer frame 1. A self - tapping screw 8 is fixedly installed inside the corner code installation hole 7. After the first aluminum alloy corner code 3 and the second aluminum alloy corner code 6 are combined with each other, they are inserted into the corner code embedding cavity 2 inside the outer frame 1. During the insertion process, the flexible rubber blocks 4 on the surface of the first aluminum alloy corner code 3 are compressed and retracted due to contact with the inner wall of the corner code embedding cavity 2. After installation in place, the self - tapping screw 8 is screwed in through the corner code installation hole 7 on the surface of the outer frame 1 for fixation. If the installation is unstable and the first aluminum alloy corner code 3 and the second aluminum alloy corner code 6 tend to脱离 the corner code embedding cavity 2, a friction cushion layer 5 is arranged on the other side of the surface of the flexible rubber block 4. When moving in the reverse direction, it will contact the inner wall of the corner code embedding cavity 2, increasing the friction force to prevent it from脱离. (Note: There is an unclear word "脱离" in the original text. It should be checked and corrected in the original content if possible. Here it is translated in a way that tries to make sense according to the context.)

[0026] There are two corner bracket embedding cavities 2. The two corner bracket embedding cavities 2 are respectively opened on both sides inside the outer frame 1. The aluminum alloy corner bracket 1 3 and aluminum alloy corner bracket 2 6 are combined and inserted into the two corner bracket embedding cavities 2 respectively, and then fixed by self-tapping screws 8.

[0027] The friction pad 5 is made of high-density polyethylene. When aluminum alloy corner bracket 1 3 and aluminum alloy corner bracket 2 6 are installed in place, if instability occurs, the friction pad 5 will contact the inner wall of the corner bracket embedding cavity 2, and the high-density polyethylene will generate a large friction force to prevent the corner bracket from falling off.

[0028] The corner bracket embedding cavity 2 is compatible with aluminum alloy corner bracket 1 3 and aluminum alloy corner bracket 2 6.

[0029] Both aluminum alloy corner bracket 1 (3) and aluminum alloy corner bracket 2 (6) are fixedly installed to the outer frame 1 by self-tapping screws 8. The self-tapping screws 8 are screwed into the corner bracket mounting holes 7 on the surface of the outer frame 1 to firmly fix the corner brackets to the outer frame 1.

[0030] There are two aluminum alloy corner brackets 1-3 and 2-6, which are fixedly installed inside the corner bracket embedding cavity 2.

[0031] The implementation principle of the composite material window frame external assembly structure in this application embodiment is as follows: Personnel align the assembled aluminum alloy corner bracket 1 (3) and aluminum alloy corner bracket 2 (6) with the corner bracket embedding cavity 2 inside the outer frame 1 and insert them. During insertion, the flexible rubber block 4 on the surface of aluminum alloy corner bracket 1 (3) will be squeezed and retracted due to contact with the inner wall of the corner bracket embedding cavity 2. After aluminum alloy corner bracket 1 (3) and aluminum alloy corner bracket 2 (6) are fully inserted into the corner bracket embedding cavity 2 and installed in place, personnel need to fix them through the corner bracket mounting holes 7 on the surface of the outer frame 1. Personnel use tools to screw self-tapping screws 8 into the corner bracket mounting holes 7 until the self-tapping screws... 8. Securely fix aluminum alloy corner bracket 1 (3) and aluminum alloy corner bracket 2 (6) to the outer frame 1. If the installation is unstable and aluminum alloy corner bracket 1 (3) and aluminum alloy corner bracket 2 (6) tend to detach from the corner bracket embedding cavity 2, the friction pad layer 5 on the surface of the flexible rubber block 4 will contact the inner wall of the corner bracket embedding cavity 2. Since the high-density polyethylene material of the friction pad layer 5 has a large coefficient of friction, it can generate sufficient friction force to effectively prevent aluminum alloy corner bracket 1 (3) and aluminum alloy corner bracket 2 (6) from detaching from the corner bracket embedding cavity 2. This not only improves the stability of the installation, but also enhances the overall structural strength and reliability of the window frame.

[0032] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
