Description

Technical Field

[0001] This application relates to the field of sealing and waterproofing of building doors and windows, and in particular to a sealing structure for the corner of a skylight. Background Technology

[0002] In the construction industry, thermally broken aluminum alloy materials are widely used in structures such as doors and windows due to their excellent thermal insulation performance, especially in skylights. Their use effectively improves indoor thermal insulation, reduces energy consumption, and creates a comfortable indoor environment. As the construction industry's requirements for energy conservation and comfort continue to increase, the application scope of thermally broken aluminum alloy materials is also expanding, playing a vital role in improving the overall performance of buildings. It not only improves the thermal insulation performance of buildings but also enhances their aesthetics and safety to a certain extent.

[0003] In skylights made of thermally broken aluminum alloy profiles, the corners are typically connected by welding. However, skylights made of thermally broken aluminum alloy profiles are usually composed of outdoor aluminum alloy profiles, nylon thermal break strips, and indoor aluminum alloy profiles. Welding the corners of the skylight to fix them together can easily melt the thermal break strips due to the high temperature generated during welding, resulting in lower production quality. Utility Model Content

[0004] To ensure the production quality of skylights, this application provides a corner sealing structure for skylights.

[0005] The technical solution for a sunroof corner sealing structure provided in this application is as follows: A sunroof corner sealing structure includes two profiles and a corner insert. Each profile has a cavity, and each end of the corner insert is used to insert into the cavity of one of the profiles. The ends of the two profiles that are close to each other are beveled and fit tightly against each other. The corner insert is a plastic corner insert.

[0006] By adopting the above technical solution, the two profiles are tightly fitted at the bevel and connected by plastic corner inserts, achieving a seal at the skylight corner and ensuring the production quality of the skylight. The plastic corner inserts are lightweight and low-cost. Furthermore, using plastic corner inserts reduces the heat transfer issues associated with aluminum alloy corner inserts, minimizing heat conduction between the two profiles through the corner inserts. This improves the thermal insulation performance of the skylight corner sealing structure, reduces heat exchange between indoors and outdoors, helps maintain a stable indoor temperature, and reduces energy consumption.

[0007] Preferably, one surface of the insert corner is provided with an injection guide groove, the injection guide groove is aligned with the connection point of the two profiles, and each profile has a connecting port on the surface near the injection guide groove, which communicates with the injection guide groove, and the two connecting ports are interconnected.

[0008] By adopting the above technical solution, on the basis of the sunroof corner sealing structure composed of two profiles and plastic corner inserts, an injection guide groove is opened on the corner insert and aligned with the connection of the two profiles. A connecting port is opened on the profile that is connected to and mutually connected with the injection guide groove. Glue is injected into the injection guide groove through the connecting port, so that the metal glue fills the injection guide groove. At this time, the metal glue will fill the connection of the two profiles, thereby improving the sealing performance of the sealing structure.

[0009] Preferably, the insertion corner is provided with multiple weight-reducing grooves.

[0010] By adopting the above technical solution, the two profiles and plastic corner brackets work together to achieve a sunroof corner seal. Multiple weight-reducing grooves on the corner brackets can reduce the weight of the corner brackets and save costs.

[0011] Preferably, each end of the insertion corner is provided with at least one reinforcing groove, and each profile cavity is provided with at least one reinforcing folding rod, which is used to slide into the corresponding reinforcing groove.

[0012] By adopting the above technical solution, the reinforcing grooves at each end of the corner bracket are slidably inserted into the reinforcing folding rods inside the profile cavity. This connection method makes the fit between the corner bracket and the profile tighter, effectively enhancing the connection stability between the corner bracket and the profile. This, in turn, makes the entire sunroof corner sealing structure more robust and reliable, capable of withstanding greater external impacts and vibrations, ensuring the sealing performance and structural integrity of the sunroof corner.

[0013] Preferably, the opening area of ​​the reinforcement groove is smaller than the area of ​​the bottom of the reinforcement groove.

[0014] By adopting the above technical solution, the reinforcing folding rod is not easy to fall out after being inserted into the reinforcing groove, which enhances the stability of the connection between the corner and the profile and ensures the firmness of the corner sealing structure of the sunroof.

[0015] Preferably, each end of the insert corner is chamfered.

[0016] By adopting the above technical solution, when the corner plug is inserted into the cavity of the profile, the chamfer can play a guiding role, making it easier for the corner plug to be inserted into the cavity of the profile, and facilitating the installation of the sunroof corner sealing structure.

[0017] Preferably, the two connecting ports are connected to the same sealing plate.

[0018] By adopting the above technical solution, the same sealing plate is snapped into both connecting openings, making it convenient and quick to seal the openings and ensuring the sealing performance and stability of the sunroof corner sealing structure. Furthermore, the metal adhesive at the contact point between the sealing plate and the connecting opening secures the sealing plate in place, making the seal more robust and reliable. The use of metal adhesive also results in a smoother and more uniform appearance at the sealing point.

[0019] Preferably, a plug rod is fixedly connected to one side of the sealing plate, and a plug groove is formed on one surface of the plug corner where an injection guide groove is formed, and the plug rod is plugged into the plug groove.

[0020] By adopting the above technical solution, the stability of the connection between the sealing plate and the corner plug can be enhanced, and the connection port can be sealed better.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. The plastic corner brackets are lightweight and low in cost, while ensuring the production quality of the skylight, reducing heat exchange between indoors and outdoors, helping to maintain a stable indoor temperature and reduce energy consumption; 2. Metal adhesive fills the joint between the two profiles, improving the sealing performance of the sealing structure; 3. Ensured the robustness of the sealing structure at the corner of the skylight.

[0027] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0028] This application discloses a sunroof corner sealing structure. (Refer to...) Figure 1 and Figure 2 The sunroof corner sealing structure includes two profiles 1 and one insert 2. Each profile 1 has a cavity 11. Each end of the insert 2 is inserted into the cavity 11 of one of the profiles 1. The ends of the two profiles 1 that are close to each other are beveled. After the profiles 1 and insert 2 are inserted, the bevels of the two profiles 1 are in close contact. The insert 2 is made of plastic, which reduces the heat conduction of the metal insert 2. The profiles 1 are generally made of thermally broken aluminum alloy.

[0029] Both ends of the insertion corner 2 are chamfered to facilitate easy insertion of the insertion corner 2 into each profile 1.

[0030] One surface of the insert 2 has an injection guide groove 21, which is aligned with the joint of the two profiles 1. One surface of each of the two profiles 1 has a connecting opening 12. After the two profiles 1 are joined, the two connecting openings 12 are interconnected and both are connected to the injection guide groove 21. The injection guide groove 21 is used to inject sealant, enhancing the sealing effect between the insert 2 and each profile 1.

[0031] Multiple weight-reducing grooves 22 are provided on the insertion corner 2. The weight-reducing grooves 22 can reduce the weight of the insertion corner 2 and save materials. The weight-reducing grooves 22 can be grooves of different shapes such as round or square.

[0032] Each end of the insert 2 is provided with at least one reinforcing groove 23, and the cavity 11 of the profile 1 is provided with at least one reinforcing folding rod 13. The reinforcing groove 23 is used to slide and engage with the reinforcing folding rod 13 in the cavity 11 of the profile 1 to enhance the stability of the connection. When installing the insert 2 and the profile 1, each reinforcing groove 23 is aligned with the corresponding reinforcing folding rod 13 and slidably inserted.

[0033] The opening area of ​​the reinforcing groove 23 is smaller than the area of ​​the bottom of the reinforcing groove 23. This structure can prevent the reinforcing folding rod 13 from easily detaching from the reinforcing groove 23.

[0034] Specifically, the reinforcing flexure 13 is located within the cavity 11 of the profile 1. The reinforcing flexure 13 is generally made of metal, such as aluminum alloy, and has a certain strength. Its shape is usually bent to allow for sliding insertion with the reinforcing groove 23. The cooperation between the reinforcing flexure 13 and the reinforcing groove 23 makes the connection between the insertion corner 2 and the profile 1 more stable.

[0035] Reference Figure 3 and Figure 4 After the sealant is applied, the same sealing plate 3 is snapped into both connecting ports 12. The sealing plate 3 can restrict the flow of sealant, ensuring the sealing effect. Moreover, the outer surface of the sealing plate 3 is flush with the corresponding surfaces of the two profiles 1, which makes the sealing structure of the sunroof corner more aesthetically pleasing.

[0036] Reference Figure 2 and Figure 4 A plug-in rod 31 is fixedly connected to one side of the sealing plate 3. A plug-in groove 24 is formed on one surface of the plug corner 2, where an adhesive injection guide groove 21 is provided. The plug-in rod 31 is inserted into the plug-in groove 24. (Refer to...) Figure 3 This connection method allows the sealing plate 3 to be more firmly fixed at the connection port 12.

[0037] The implementation principle of the sunroof corner sealing structure in this application embodiment is as follows: the plastic insert 2 is inserted into the cavity 11 of the profile 1 to complete the connection of the sunroof corner. The setting of the glue injection guide groove 21 and the connecting port 12 facilitates the injection of sealant and enhances the sealing performance of the corner. The weight reduction groove 22 reduces the weight of the insert 2, saving materials. The cooperation between the reinforcing folding rod 13 and the reinforcing groove 23 enhances the stability of the connection. Compared with the traditional welding connection method, this structure solves the problem of the high temperature of welding melting the heat insulation strip, and improves the production quality and performance of the sunroof.

[0038] 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.
