Description

Technical Field

[0001] This application relates to the field of building door and window technology, and in particular to a corner protection structure for door and window structures and a door and window structure. Background Technology

[0002] In the current field of building doors and windows, with the diversification of door and window functions and the increasing complexity of their structures, the shapes of their corners are becoming increasingly complex, and the number of sharp edges is increasing, leading to a significant increase in safety hazards. To address this issue, the industry typically adopts the method of adding a covering protective structure to the sharp corners for local protection.

[0003] Currently, the mainstream protection method is to add additional protective corner protectors after the profile corners are assembled. However, this method has drawbacks: First, the protection range is limited, only covering the internal corner area, while a large number of sharp edges on the outer side and end face of the profile remain exposed, still posing a risk of impact; Second, it generally relies on post-installation fixing methods such as clips or adhesives, which have inherent disadvantages such as easy aging and detachment, and insufficient installation firmness. This not only affects the durability of protection, but may also lead to a decrease in overall sealing performance due to structural interference or seal damage during the installation process. Utility Model Content

[0004] To address the shortcomings of the aforementioned related technologies, such as limited protection range and insufficient installation stability, this utility model provides a corner protection structure for doors and windows, as well as a door and window structure.

[0005] On the one hand, this application provides a corner protection structure for door and window structures, adopting the following technical solution: A corner protection structure for doors and windows includes door and window profiles and multiple protective components. Each corner of the door and window profile is provided with a reserved notch for installing the protective component. The protective component is located at the reserved notch, and the corner of the protective component is rounded.

[0006] By adopting the above technical solutions, the protection of the corners of doors and windows can be improved, the installation can be made more secure, and the sealing performance can be effectively enhanced.

[0007] Optionally, the door and window profile is further provided with a pre-reserved notch for connectors, and the pre-reserved notch for connecting adjacent protective components is provided with a connector.

[0008] The above solution allows for the connection and positioning of adjacent protective components using connectors, which helps improve the stability of the overall structure and ease of assembly.

[0009] Optionally, the corners of the connector are rounded.

[0010] The above solution can eliminate any sharp corners that may be present in the connectors themselves, thus avoiding new safety hazards.

[0011] Optionally, the plurality of protective components include a first protective component and a second protective component, wherein the first protective component is a nylon protective component located outdoors, and the second protective component is a plastic protective component located indoors.

[0012] The above solution enables the configuration of protective components with different performance characteristics according to the needs of different indoor and outdoor environments. The outdoor components have stronger weather resistance, while the indoor components have lower costs, achieving a good balance between performance and cost.

[0013] Optionally, the connector includes a rubber connector that connects adjacent first protective members and second protective members, adjacent first protective members, or adjacent second protective members.

[0014] The above solution utilizes the elasticity of rubber to form a flexible connection between protective components of different materials or locations, effectively absorbing temperature difference deformation and avoiding stress concentration.

[0015] Optionally, the door and window profile is provided with a profile cavity, and the profile cavity is provided with an angle bracket connected to the protective component.

[0016] The above solution enables the use of corner brackets to provide internal support and connection for the protective components, significantly improving the strength and reliability of the protective component installation.

[0017] Optionally, an adhesive is provided between the protective component and the corner bracket and the door / window profile.

[0018] The above solution achieves the goal of filling gaps with adhesive and forming a strong chemical bond, further enhancing the fixing effect and improving the overall sealing performance.

[0019] Optionally, the protective component has an injection port for injecting the adhesive, and the corner bracket has an injection channel communicating with the injection port.

[0020] The above method enables controllable injection of adhesive, ensuring that the adhesive can fully and evenly fill all preset gaps, thereby improving bonding quality and sealing effect.

[0021] Optionally, the corner protection structure of the door and window structure further includes a frame profile, which cooperates with the door and window profile, wherein the inner corner of the frame profile is constructed as a chamfer that matches the corner of the protective member.

[0022] The above solution achieves a proper fit between the frame profile and the door / window profile, thus improving sealing performance.

[0023] Another objective of this application is to provide a door and window structure having a corner protection structure.

[0024] The above solution provides a door and window product with more corner security features and higher installation stability.

[0025] This application has at least the following beneficial effects: 1. By setting pre-reserved notches and embedding rounded corner protective parts at multiple corners of door and window profiles, sharp edges on both the inner and outer sides can be more fully covered, significantly improving the protective effect, installation firmness and sealing performance; 2. By combining embedded installation, corner bracket mechanical connection, and adhesive bonding, the bonding strength between the protective components and the profile is greatly improved, effectively reducing the risk of detachment; 3. The embedded structure and injection process achieve strong adhesion while filling gaps, which not only enhances installation stability but also improves overall sealing. 4. By differentiating between protective components made of different materials for indoor and outdoor use (such as outdoor nylon and indoor plastic) and rubber elastic connectors, it can adapt to the requirements of different environments for weather resistance, strength and cushioning performance; 5. The protective components and profiles are designed as a single unit, and the matching frame profiles have chamfers to further improve the sealing effect. Attached Figure Description

[0028] This application is based on the inventor's insight that related technologies, from the design stage, do not consider protective components as an essential part of door and window profiles, resulting in poor protective effects, weak reliability, and the separation of the protective structure from the main body of the door and window. Therefore, there is an urgent need for a new protective solution that can be integrated into the profile design, completely eliminate sharp exposed corners from the manufacturing stage, and provide a more secure installation.

[0029] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0030] This application discloses a corner protection structure for door and window structures. (Refer to...) Figure 1 The corner protection structure of the door and window structure includes door and window profiles 10, multiple protective components, connectors 30, corner brackets, and frame profiles (not shown in the figure).

[0031] Reference Figure 1 and Figure 2 The door and window profile 10 has a profile cavity, and the original multiple exposed acute angles of the door and window profile 10 are constructed to form protective component reserved notches for installing the protective components and connecting component reserved notches 12 for installing the connecting components 30. The protective component reserved notches may include a first protective component reserved notch 11a that matches the shape and size of the first protective component 21 and a second protective component reserved notch 11b that matches the shape and size of the second protective component 22. The profile cavity includes a first profile cavity 13a that can accommodate a first corner bracket and a second profile cavity 13b that can accommodate a second corner bracket.

[0032] Reference Figure 1 , Figure 2 and Figure 3 The protective component has a pre-reserved notch, and its sharp corners are rounded to prevent scratches and injuries. The plurality of protective components may include, for example, a first protective component 21 and a second protective component 22. The first protective component 21 is installed at the pre-reserved notch 11a, and the second protective component 22 is installed at the pre-reserved notch 11b.

[0033] The protective components can be designed to adapt to both outdoor and indoor environments. Taking the example of the first protective component 21 being located outdoors and the second protective component 22 being located indoors, the first protective component 21 can be made of nylon, while the second protective component 22 can be made of plastic. The nylon protective component possesses high strength, high weather resistance, and excellent anti-aging properties, while the plastic protective component is lightweight, low-cost, and has good plasticity.

[0034] The protective component may also have an injection port for injecting adhesive, so as to further bond and fix the protective component to the door and window profile 10, thereby improving the robustness of the protective structure. For example, the first protective component 21 may have a first injection port 21a, and the second protective component 22 may have a second injection port 22a.

[0035] Reference Figure 1 and Figure 5 The connector 30 is installed at the reserved notch 12 of the connector to connect and support the adjacent protective components. The connector 30 can be made of elastic materials such as rubber, and the elasticity of rubber can be used to form a flexible transition and buffer between protective components of different materials or positions.

[0036] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5 The profile cavity is provided with corner brackets that connect to the protective component. The first profile cavity 13a is provided with a first corner bracket 41 that connects to the first protective component 21, and the second profile cavity 13b is provided with a second corner bracket 42 that connects to the second protective component 22. The first protective component 21 and the second protective component 22 can further enhance the structural strength of the corner protection structure of the door and window structure.

[0037] The corner bracket may be provided with an adhesive flow channel communicating with the adhesive injection port on the protective component. The first corner bracket 41 is provided with a first adhesive flow channel 41a communicating with a first adhesive injection port 21a, and the second corner bracket 42 is provided with a second adhesive flow channel 42a communicating with a second adhesive injection port 22a. The adhesive can be injected through the adhesive injection port, fully filling the preset gap through the adhesive flow channel, and after curing, forming a strong and sealed adhesive, realizing the connection between the protective component, the corner bracket and the door and window profile 10.

[0038] The frame profile is fitted with the door / window profile 10. The inner corners of the frame profile are chamfered to match the corners of the protective member, thereby improving the sealing strength when the door / window is closed.

[0039] The implementation principle of a corner protection structure for doors and windows in this application is as follows: This application reduces safety hazards at the corners of doors and windows through an integrated design. Notches are pre-drilled at the corners of the door and window profiles 10, and rounded corner protectors are embedded to reduce the safety risks posed by sharp edges. Outdoor nylon protective components and indoor plastic protective components are used to improve weather resistance and strength in different application scenarios. Adjacent components are flexibly connected via rubber connectors to compensate for thermal deformation. Corner brackets provide rigid support, and the injection molding process fills gaps, ensuring structural strength and reliable sealing. The frame profiles are designed with chamfers to match the door and window profiles 10, forming a smooth sealing interface when closed, reducing safety hazards and improving sealing and durability.

[0040] This application also discloses a door and window structure having the corner protection structure described above.

[0041] The implementation principle of a door and window structure in this application embodiment is as follows: by setting the corner protection structure of the door and window structure, more sharp edges of the door and window profiles are protected. The protective component is embedded and installed with the profile to form an integral structure, which improves the sealing performance and reduces safety hazards. The connector 30 and the glue injection structure further improve the firmness and sealing of the connection.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
