Description

Technical Field

[0001] This application relates to the field of doors and windows, and in particular to a conversion frame structure. Background Technology

[0002] In the field of architectural doors and windows, inward-opening window systems are a common design form, widely used in various types of buildings. They not only meet the basic needs of indoor ventilation but also enhance the safety and aesthetics of buildings to a certain extent. With the continuous development of the construction industry, people's requirements for the quality and performance of inward-opening window systems are also increasing. Ensuring the stable operation and good user experience of inward-opening window systems in different scenarios has become a key issue of concern within the industry.

[0003] In traditional inward-opening window systems, glazing bead strips are typically installed on the interior side, whether in the opening or fixed section. However, when encountering solid walls, interior glazing becomes difficult. In such cases, a transition profile (transition frame) is needed to allow the glazing bead strips to be installed on the exterior side. When addressing the fit between the transition frame and the main frame, the conventional approach is to achieve a near-seamless connection. This requires the main frame to be pre-assembled at the corners before inserting the transition frame, ensuring precise inner dimensions of the main frame, and requiring extremely high precision in the manufacturing of the transition frame.

[0004] However, errors often occur during the processing of the conversion frame or the main frame. In order to reduce the situation where the conversion frame is difficult to fit into the main frame, the production size of the conversion frame is usually smaller or the production size of the main frame is usually larger. This results in a gap fit between the conversion frame and the main frame, and the installation quality of the conversion frame is low. Utility Model Content

[0005] To ensure the installation quality of the conversion frame, this application provides a conversion frame structure.

[0006] The conversion frame structure provided in this application adopts the following technical solution: A conversion frame structure includes a main frame and a conversion frame for snapping into the main frame. A ring of protrusions is fixedly connected around the perimeter of the conversion frame, and the protrusions abut against the inner sidewall of the main frame.

[0007] By adopting the above technical solution, when installing the conversion frame and the main frame, the conversion frame is inserted into the main frame and tapped until the protrusion is engaged into the main frame under external force and abuts against the inner side of the main frame. If the size of the protrusion is larger than the gap between the conversion frame and the main frame, the excess part of the protrusion can be knocked off while tapping the protrusion into the main frame so that the protrusion can smoothly enter the main frame. This helps to ensure the installation quality of the conversion frame and reduces the occurrence of gaps between the main frame and the conversion frame.

[0008] Preferably, the distance between the outer wall of the protrusion and the outer wall of the conversion frame is 0.5 mm.

[0009] By adopting the above technical solution, the size is reasonably controlled while ensuring that the protrusion can play a snapping role, and the protrusion can be knocked off smoothly when the size is large.

[0010] Preferably, a mounting groove is formed on the inner side wall of the main frame, and a sealing ring for abutting against the inner side wall of the conversion frame is engaged in the mounting groove.

[0011] By adopting the above technical solution, an installation groove is opened on the inner side wall of the main frame and a sealing ring is snapped in place to abut against the inner side wall of the conversion frame, which can enhance the sealing between the conversion frame and the main frame and facilitate the main frame to provide better support for the conversion frame.

[0012] Preferably, a mounting ring groove communicating with the mounting slot is formed on one surface of the main frame, and a support ring is inserted into the mounting ring groove, the support ring abutting against the side wall of the sealing ring near the bottom wall of the mounting slot.

[0013] By adopting the above technical solution, after the conversion frame and the main frame are connected, the support ring is aligned with the mounting ring groove, and the support ring is inserted into the mounting ring groove. During this process, the support ring pushes the sealing ring to gradually press against the outer wall of the conversion frame in the direction closer to the conversion frame. At the same time, the sealing ring applies a force to the support ring to press against the bottom wall of the mounting groove, thereby strengthening the connection between the support ring and the main frame.

[0014] Preferably, the end of the support ring away from the mounting ring groove has a pointed tip.

[0015] By adopting the above technical solution, the support ring is easier to insert into the installation ring groove, the resistance during the insertion process is reduced, and the installation of the support ring can be achieved more smoothly.

[0016] Preferably, the mounting groove includes a bottom end and an open end, the diameter of the open end is smaller than the inner diameter of the bottom end, and the sealing ring includes a sealing end that is tightly inserted into the open end, and a connecting end that is tightly inserted into the bottom end.

[0017] By adopting the above technical solution, the diameter of the mounting groove opening is smaller than the inner diameter of the groove bottom. The sealing end of the sealing ring is tightly inserted into the opening end, and the connecting end is tightly inserted into the groove bottom end. This structural design can effectively limit the sealing ring from detaching from the mounting groove and ensure the stable installation of the sealing ring in the mounting groove.

[0018] Preferably, the sealing end is made of an elastic material and is tightly abutted against the outer wall of the conversion frame.

[0019] By adopting the above technical solution, the sealing end is made of elastic material and is tightly pressed against the outer wall of the conversion frame, which can further enhance the sealing effect.

[0020] Preferably, the conversion frame and the main frame are fastened together by multiple screws.

[0021] By adopting the above technical solution, the protrusions that are fixedly connected around the conversion frame are pressed against the inner side wall of the main frame to achieve initial positioning and connection. Then, multiple screws are used to fasten the conversion frame to the main frame, which can make the connection between the conversion frame and the main frame more solid and improve the overall stability of the conversion frame structure.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. It facilitates the installation quality of the transition frame and reduces the occurrence of gaps between the main frame and the transition frame; 2. Reinforce the connection between the support ring and the main frame; 3. Ensure the sealing ring is stably installed in the mounting groove. Attached Figure Description

[0026] The following is in conjunction with the appendix Figures 1-2 This application will be described in further detail.

[0027] This application discloses a conversion frame structure. (Refer to...) Figure 1 and Figure 2 The conversion frame 2 structure includes a main frame 1 and a conversion frame 2. The conversion frame 2 is used to snap into the main frame 1. A ring of protrusions 21 is fixedly connected around the conversion frame 2. The protrusions 21 are used to press against the inner side wall of the main frame 1.

[0028] When assembling the main frame 1 and the adapter frame 2, align the adapter frame 2 with the main frame 1 and insert the adapter frame 2 into the main frame 1 until the protrusion 21 contacts the main frame 1. Then, use a flexible rubber mallet or other tools to tap the protrusion 21 and the adapter frame 2 to make the protrusion 21 smoothly engage with the main frame 1, facilitating a tight connection between the main frame 1 and the adapter frame 2. Alternatively, during the insertion of the adapter frame 2 into the main frame 1, partially or completely knock off the protrusion 21 so that the adapter frame 2 can smoothly insert into the main frame 1 and fit tightly together.

[0029] The main frame 1 or transition frame 2 is typically a rectangular frame structure, made of aluminum alloy, which is lightweight, high-strength, and corrosion-resistant. Protrusions 21 are fixedly connected around the perimeter of the frame, forming a ring around its circumference. The material of protrusions 21 is the same as the frame, and they can be manufactured using a one-piece molding process to ensure a secure connection.

[0030] The distance between the outer wall of the protrusion 21 and the outer wall of the conversion frame 2 is 0.5mm. The assembly of the conversion frame 2 and the main body is allowed to have a certain error, which is generally ±0.5mm. The size of the protrusion 21 is set in this way to fill the gap between the conversion frame 2 and the main frame 1 due to the error, or to completely knock off the protrusion 21 to cover the assembly between the conversion frame 2 and the main frame 1.

[0031] Reference Figure 1 and Figure 2 The inner sidewall of the main frame 1 is provided with an annular mounting groove 11. A sealing ring 3 is installed in the mounting groove 11. The shape and size of the sealing ring 3 are adapted to the mounting groove 11. The sealing ring 3 is used to press against the outer sidewall of the conversion frame 2.

[0032] The sealing ring 3 includes a sealing end 31 and a connecting end 32. The mounting groove 11 includes an open end 111 and a bottom end 112. The sealing end 31 is engaged in the open end 111, and the connecting end 32 is engaged in the bottom end 112. The diameter of the open end 111 is smaller than the inner diameter of the bottom end 112, thus preventing the sealing ring 3 from disengaging from the mounting groove 11.

[0033] The sealing end 31 is an elastic element, usually made of rubber, which has good elasticity and sealing performance. The sealing end 31 is tightly pressed against the outer wall of the conversion frame 2, which can strengthen the connection between the main frame 1 and the conversion frame 2.

[0034] To facilitate a tighter fit between the sealing ring 3 and the outer wall of the conversion frame 2, a mounting ring groove 12 is formed on one surface of the main frame 1, which communicates with the mounting groove 11. A support ring 4 is inserted into the mounting ring groove 12, located between the sealing ring 3 and the bottom wall of the mounting groove 11, and presses against the sealing ring 3 so that the sealing ring 3 fits tightly against the outer wall of the conversion frame.

[0035] Reference Figure 1 and Figure 2 The support ring 4 includes a ring body 41 and a tip 42. The ring body 41 is inserted into the mounting ring groove 12, which compresses the sealing ring 3 and applies a force to the sealing ring 3 against the conversion frame 2. The tip 42 is located at the end of the support ring 4 away from the mounting ring groove 12. The design of the tip 42 allows the support ring 4 to be inserted relatively smoothly along the mounting ring groove 12 between the sealing ring 3 and the bottom wall of the mounting groove 11.

[0036] The support ring 4 fits tightly with the mounting ring groove 12 and is fixed within the mounting ring groove 12 by insertion. This structural design of the support ring 4 allows it to provide additional support for the sealing ring 3 without affecting its normal operation, thereby improving sealing performance.

[0037] The conversion frame 2 and the main frame 1 are also fastened together by multiple screws 5. The screws 5 pass through corresponding parts of the conversion frame 2, the sealing ring 3, the support ring 4, and the main frame 1 in sequence, tightly connecting the conversion frame 2 and the main frame 1 together. At the same time, the sealing ring 3 and the support ring 4 are securely installed on the structure of this conversion frame 2.

[0038] The implementation principle of the conversion frame structure in this application embodiment is as follows: This conversion frame 2 structure, by setting protrusions 21 around its perimeter, ensures that the protrusions 21 tightly abut against the inner wall of the main frame 1, reducing gaps caused by processing errors and improving the installation quality of the conversion frame 2 and the main frame 1. Simultaneously, a sealing ring 3 is engaged within the mounting groove 11 on the inner wall of the main frame 1, further enhancing the sealing performance. The support ring 4 provides additional support to the sealing ring 3, improving the sealing effect. The conversion frame 2 and the main frame 1 are fastened together with screws 5, ensuring the stability of the connection. Compared with the traditional conversion frame 2 structure, this structure is more stable, has higher installation quality, and can better meet the usage requirements of building doors and windows.

[0039] 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.
