Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example 1 Please see Figure 1-5 The present invention provides the following technical solution: an environmentally friendly door and window profile structure, including a corner bracket 1, connecting blocks 2 are fixedly connected to both ends of the corner bracket 1, and frame profiles 3 are tightly sleeved on both ends of the corner bracket 1. The connecting blocks 2 and the frame profiles 3 are fixed by a fixing component 4, and a sealing component 5 is fixed on one side of the frame profiles 3. The fixing component 4 includes a fixing screw 41. One end of the frame profile 3 is threadedly connected to the fixing screw 41. One end of the fixing screw 41 is fixedly connected to a cylindrical fixing block 42. The other end of the fixing screw 41 is fixedly connected to a rotating block 43. A protective component 45 is provided on one side of the rotating block 43.

[0018] Specifically, a fixing hole is provided on one side of the connecting block 2, and the cylindrical fixing block 42 is tightly inserted into the fixing hole.

[0019] By adopting the above technical solution, the frame profile 3 and the corner bracket 1 are tightly inserted. Then, the rotating block 43 is rotated, which drives the fixing screw 41 to rotate. The rotation of the fixing screw 41 will drive the cylindrical fixing block 42 to move, so that the cylindrical fixing block 42 is inserted into the fixing hole on one side of the connecting block 2, thereby completing the fixing between the frame profile 3 and the corner bracket 1.

[0020] Specifically, the protective component 45 includes an external threaded tube seat 451, which is fixedly connected to one side of the frame profile 3. An internal threaded tube seat 452 is threadedly connected to the surface of the external threaded tube seat 451, and a protective limit cover 453 is fixedly connected to one end of the internal threaded tube seat 452.

[0021] By adopting the above technical solution, the internal threaded pipe seat 452 and the external threaded pipe seat 451 are connected to facilitate the installation of the protective limit cover 453. After the protective limit cover 453 is installed, one side of its interior fits against one side of the rotating block 43, thereby facilitating the protection of the fixing screw 41 through the protective limit cover 453, and at the same time improving the stability of the fixing screw 41 and preventing its displacement.

[0022] Specifically, the surface of the protective limit cover 453 is surrounded and fixedly connected with a rubber anti-slip strip 454, and the surface of the rotating block 43 is surrounded and fixedly connected with an auxiliary rod 44.

[0023] By adopting the above technical solution, the rubber anti-slip strip 454 makes it easy to rotate the protective limit cover 453, and the auxiliary rod 44 makes it easy to rotate the rotating block 43, so that the device can be used without the aid of tools.

[0024] Specifically, the inner wall of the external threaded pipe seat 451 is in contact with the rotating block 43.

[0025] By adopting the above technical solution, the inner wall of the external threaded pipe seat 451 and the rotating block 43 fit together, which facilitates the limiting of the fixing screw 41.

[0026] In this embodiment, when in use: the frame profile 3 and the corner bracket 1 are tightly inserted, and then the rotating block 43 is rotated. The rotating block 43 drives the fixing screw 41 to rotate. The rotation of the fixing screw 41 will drive the cylindrical fixing block 42 to move, so that the cylindrical fixing block 42 is inserted into the fixing hole on one side of the connecting block 2, thereby completing the fixation between the frame profile 3 and the corner bracket 1. The internal threaded tube seat 452 and the external threaded tube seat 451 are connected to facilitate the installation of the protective limit cover 453. After the protective limit cover 453 is installed, one side of its interior fits against one side of the rotating block 43, thereby facilitating the protection of the fixing screw 41 through the protective limit cover 453, and at the same time improving the stability of the fixing screw 41 and preventing its displacement. This allows the device to easily connect and fix the corner bracket 1 and the frame profile 3 during use, and the structure is stable.

[0027] Example 2 The difference between this embodiment and embodiment 1 is that, specifically, the sealing component 5 includes a base layer 51, a buffer layer 52 is fixedly connected to one side of the base layer 51, a sealing layer 53 is fixedly connected to one side of the buffer layer 52, and a protective layer 54 is fixedly connected to one side of the sealing layer 53.

[0028] By adopting the above technical solutions, the base layer 51 is made of nitrile rubber, which has good oil resistance, aging resistance, and mechanical strength, providing stable structural support for the entire sealing gasket and preventing excessive deformation of the gasket during assembly and use. The buffer layer 52 is located above the base layer 51 and has several arrayed hemispherical elastic protrusions inside. The elastic protrusions are made of natural rubber, which has excellent elasticity and resilience, effectively mitigating the squeezing impact generated by the glass profile during opening, closing, and vibration, reducing rigid contact between the sealing gasket and the glass / profile, thereby reducing wear. The sealing layer 53 is the core structure for achieving the sealing function and is made of modified EPDM rubber. EPDM rubber itself has good weather resistance, ozone resistance, and sealing performance, further enhancing its anti-aging and wear resistance. The protective layer 54 is located above the sealing layer 53 and is made of polytetrafluoroethylene (PTFE) film. PTFE has excellent corrosion resistance, abrasion resistance, and high temperature resistance, effectively isolating the sealing layer 53 from external rainwater, dust, ultraviolet rays, and other factors, while reducing frictional damage between the sealing gasket and the glass.

[0029] Specifically, an anti-aging layer is provided inside the sealing layer 53.

[0030] By adopting the above technical solution, the anti-aging layer is the effect layer. By adding anti-aging agents to the raw materials of the sealing layer 53, the anti-aging effect is improved.

[0031] In this embodiment, the base layer 51 is made of nitrile rubber, which has good oil resistance, aging resistance and mechanical strength, and can provide stable structural support for the entire sealing gasket, preventing excessive deformation of the sealing gasket during assembly and use; the buffer layer 52 is located above the base layer 51, and has several hemispherical elastic protrusions arranged in an array inside. The elastic protrusions are made of natural rubber, which has excellent elasticity and resilience, and can effectively alleviate the squeezing impact generated by the glass profile during opening and closing and vibration, reduce the rigid contact between the sealing gasket and the glass and profile, thereby reducing wear; the sealing layer 53 is the core structure for realizing the sealing function, and is made of modified EPDM rubber. Ethylene propylene diene monomer (EPDM) rubber itself has good weather resistance, ozone resistance, and sealing performance. To further improve its anti-aging and wear resistance, the protective layer 54 is located above the sealing layer 53 and is made of polytetrafluoroethylene (PTFE) film. PTFE has excellent corrosion resistance, abrasion resistance, and high temperature resistance, which can effectively isolate external factors such as rainwater, dust, and ultraviolet rays from eroding the sealing layer 53, while reducing frictional damage between the gasket and the glass, thereby facilitating the improvement of the service life of the sealing component 5.

[0033] The working principle and usage process of this utility model are as follows: In use, the two frame profiles 3 and the corner bracket 1 are connected at both ends to facilitate the connection of the two frame profiles 3. Then, they are fixed by the fixing component 4. This structure is convenient to use and does not require tools. The sealing component 5 of this structure has a long service life. When using the fixing component 4, the frame profiles 3 and the corner bracket 1 are tightly inserted. Then, the rotating block 43 is rotated, which drives the fixing screw 41 to rotate. The rotation of the fixing screw 41 drives the cylindrical fixing block 42 to move, allowing the cylindrical fixing block 42 to insert into the fixing hole on one side of the connecting block 2, thus completing the fixation between the frame profiles 3 and the corner bracket 1. The internal threaded tube seat 452 and the external threaded tube seat 451 are connected to facilitate the installation of the protective limit cover 453. After the protective limit cover 453 is installed, one side of its interior fits against one side of the rotating block 43, thus allowing the protective limit cover 453 to... To protect the fixing screw 41 and improve its stability, preventing displacement, the device can be easily connected and fixed between the diagonal bracket 1 and the frame profile 3 during use, resulting in a stable structure. When using the sealing component 5, the base layer 51 is made of nitrile rubber, which has good oil resistance, aging resistance, and mechanical strength, providing stable structural support for the entire sealing gasket and preventing excessive deformation during assembly and use. The buffer layer 52 is located above the base layer 51 and contains several arrayed hemispherical elastic protrusions made of natural rubber, which has excellent elasticity and resilience, effectively mitigating the squeezing impact generated by the glass profile during opening, closing, and vibration, reducing rigid contact between the sealing gasket and the glass / profile, thereby reducing wear. The sealing layer 53 is the core structure for achieving the sealing function and is made of modified EPDM rubber. Ethylene propylene diene monomer (EPDM) rubber itself has good weather resistance, ozone resistance, and sealing performance. To further improve its anti-aging and wear resistance, the protective layer 54 is located above the sealing layer 53 and is made of polytetrafluoroethylene (PTFE) film. PTFE has excellent corrosion resistance, abrasion resistance, and high temperature resistance, which can effectively isolate external factors such as rainwater, dust, and ultraviolet rays from eroding the sealing layer 53, while reducing frictional damage between the gasket and the glass, thereby facilitating the improvement of the service life of the sealing component 5.
