Description

Technical Field

[0001] This utility model relates to the field of aluminum profile technology, specifically to an aluminum profile structure for the upper frame of a door or window with insert strips. Background Technology

[0002] With the acceleration of urbanization and the booming development of the construction industry, the scale of construction projects continues to expand, placing higher demands on the efficiency and quality of door and window installation. In recent years, significant breakthroughs have been made in aluminum profile processing technology, providing a technological foundation for innovation in door and window frame structures. High-precision extrusion molding technology enables the integrated production of aluminum profiles with complex cross-sections, controlling the dimensional accuracy of the profiles within ±0.1mm, meeting the stringent precision requirements of new structures. The widespread use of CNC machining equipment allows for the rapid and precise processing of various special-shaped slots, reinforcing ribs, and other structures.

[0003] There are many existing technologies for aluminum profiles used in doors and windows, such as:

[0004] Chinese Patent (Application No.: CN202421225355.6) discloses a deformation-resistant aluminum profile, including a bottom strip for a door / window frame. The bottom strip has an internal channel, with first plastic pads tightly attached to the upper and lower ends of the inner wall of the internal channel. A first stainless steel rod is fixed between the two first plastic pads. Second stainless steel rods are welded to both sides of the outer wall of the first stainless steel rod, and a second plastic pad is fixed to the other end of the second stainless steel rod. A strip plate is fixed inside the track of the bottom strip. This invention achieves a hollow, heat-insulating effect in the bottom strip through the internal channel. The cross-shaped stainless steel rod structure provides support within the internal channel, giving the bottom strip excellent deformation resistance. The multi-layered structure of the bottom strip ensures its wear and heat resistance.

[0005] Traditional aluminum profiles for door and window frames are mostly fixed cavity structures with pre-defined internal space dimensions (e.g., only suitable for door and window sashes or sealing strips of a certain thickness). When the thickness of the door and window sash or the specifications of the sealing components change, new molds need to be made to customize the profiles, which is costly and time-consuming. If wall errors cause inconsistent installation gaps during on-site construction, the fixed structure cannot be adjusted, which can easily lead to excessive gaps causing air leakage or excessive compression causing the profiles to deform. Utility Model Content

[0006] This utility model addresses the technical problems existing in the prior art by providing an aluminum profile structure for insert-type door and window upper frames. It solves the problem that traditional door and window aluminum profiles are mostly fixed cavity structures, which cannot be adjusted when the thickness of the door and window sash or the specifications of the sealing components change, thus reducing the applicability of the aluminum profile upper frame.

[0007] To achieve the above objectives, this utility model provides an aluminum profile structure for a strip-type door and window upper frame, including a profile frame body. Two symmetrical cavities are arranged inside the profile frame body, and an adjustment component is installed inside each cavity. The adjustment component includes a limiting plate, and a bidirectional bolt is threaded to the upper center position inside the limiting plate. By rotating the bidirectional bolt, the two limiting plates are synchronously driven to move relative to each other or in opposite directions, adjusting the distance between the two limiting plates. A sealing strip is provided on one side of each limiting plate.

[0008] The beneficial effects of this utility model are:

[0009] 1. When installing aluminum profiles and door / window sashes, the two limiting plates are driven to move synchronously relative to each other or in opposite directions by rotating the bidirectional bolts. The distance between the two limiting plates can be adjusted so that the same profile can be used to fit door / window sashes of different thicknesses, eliminating the need for customized profiles and improving the applicability of the profiles.

[0010] 2. During use, the sealing strip on one side of the limiting plate is squeezed or released synchronously with the movement of the limiting plate, dynamically adjusting the sealing pressure to ensure that the doors and windows maintain good airtight performance under different working conditions.

[0011] Based on the above technical solution, the present invention can be further improved as follows.

[0012] Preferably, a guide post is fixedly connected to the bottom of the profile frame.

[0013] The beneficial effect of adopting the above-mentioned further solutions is that it provides a positioning reference for the installation of door and window sashes, reducing alignment errors during installation.

[0014] Preferably, the upper part of the two limiting plates is threaded with several one-way bolts.

[0015] The beneficial effects of adopting the above-mentioned further solutions are that the limiting plate is more firmly connected to the profile frame, preventing the limiting plate from shifting due to vibration during the opening and closing of doors and windows, while strengthening the structural strength of the limiting plate and reducing local stress concentration.

[0016] Preferably, a mounting groove is fixedly connected to one side of the sealing strip, and the mounting groove is engaged with the inside of the mounting strip on the lower side of the limiting plate.

[0017] The advantages of adopting the above-mentioned further solution are that it can adaptively fit with the adjustment of the limiting plate to maintain sealing pressure; at the same time, the snap-fit ​​structure facilitates the replacement of the sealing strip and improves maintenance convenience.

[0018] Preferably, a strip is provided on one side of the profile frame, and dovetail grooves are symmetrically provided at the upper and lower ends of the strip. Dovetail strips are symmetrically fixedly connected to the upper and lower ends inside the profile frame, and the dovetail strips are engaged and connected inside the dovetail grooves.

[0019] The advantages of adopting the above-mentioned further solutions are that they improve the aesthetics of aluminum profiles while ensuring their structural strength, and the connection method is simple, making it easy to disassemble and repair later, thus improving the convenience of maintaining aluminum profiles.

[0020] Preferably, a connecting strip is engaged between the two profile frames, and several reinforcing plates are fixedly connected inside the connecting strip.

[0021] The beneficial effect of adopting the above-mentioned further solution is that a "rigid support skeleton" can be formed at the splicing of the profile frame, which can effectively disperse the bending moment and shear force generated by external forces, enhance the overall rigidity, and distribute the load.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0023] By rotating the bidirectional bolt, two limiting plates are driven to move synchronously relative to each other or in opposite directions. The distance between the two limiting plates is adjusted so that the same profile can be adapted to door and window sashes of different thicknesses, eliminating the need for customized profiles and improving the applicability of the profiles. The "adjustment + adaptation" mode replaces the traditional "customization + measurement" process. During construction, only the bidirectional bolt needs to be rotated to compensate for wall errors. Moreover, the sealing strip is installed on the lower side of the limiting plate. By reasonably adjusting the distance between the two limiting plates, the effective contact of the sealing strip with the door and window sash is effectively ensured, guaranteeing stable sealing performance.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0034] Please see Figures 1-4 As shown, this embodiment provides an aluminum profile structure for a strip-type door and window upper frame, including a profile frame 1. Considering that traditional door and window aluminum profiles are mostly fixed cavity structures, they cannot be adjusted when the thickness of the door and window sash or the specifications of the sealing components change, thus reducing the applicability of the aluminum profile upper frame. Therefore, two cavities 11 are symmetrically arranged inside the profile frame 1. An adjustment component 2 is provided inside the cavity 11. The adjustment component 2 includes a limiting plate 21. A bidirectional bolt 22 is threadedly connected to the upper center position inside the limiting plate 21. By rotating the bidirectional bolt 22, the two limiting plates 21 are synchronously driven to move relative to each other or in opposite directions, thereby adjusting the distance between the two limiting plates 21. A sealing strip 24 is provided on one side of the limiting plate 21.

[0035] In summary, the improvement of this embodiment lies in:

[0036] By rotating the bidirectional bolt 22, the two limiting plates 21 are driven to move synchronously relative to each other or in opposite directions, adjusting the distance between the two limiting plates 21. This allows the same profile to be adapted to door and window sashes of different thicknesses, eliminating the need for customized profiles and improving the applicability of the profiles. The "adjustment + adaptation" mode replaces the traditional "customization + measurement" process. During installation, there is no need to customize the profiles in advance. The internal space of the frame can be adjusted in real time by rotating the bidirectional bolt 22, which is especially suitable for non-standard sized doors and windows or for correcting on-site construction errors.

[0037] Based on the above, other structures also need to be disclosed in detail, such as:

[0038] In order to improve the quick positioning of the door and window sash during installation, a guide post 12 is fixedly connected to the bottom of the profile frame 1. The guide post 12 is fixed to the bottom of the profile frame 1 to provide a positioning reference for the installation of the door and window sash and reduce the alignment error during installation.

[0039] To effectively ensure the stability of the limiting plates 21 during use and prevent structural deformation that could affect the installation and sealing performance of the aluminum profiles for doors and windows, several one-way bolts 23 are threaded onto the upper part of the two limiting plates 21. After determining the position of the two limiting plates 21, multiple one-way bolts 23 are threadedly installed from one side of the profile frame 1. Each one-way bolt 23 passes through the interior of both limiting plates 21, simultaneously fixing the installation position of the two limiting plates 21 and more firmly connecting the limiting plates 21 to the profile frame 1. This prevents the limiting plates 21 from shifting due to vibration during the opening and closing of doors and windows, while also strengthening the structural strength of the limiting plates 21 and reducing local stress concentration. The one-way bolts 23 can fix the position of the limiting plates 21 at multiple points. By tightening or loosening the one-way bolts 23, the position of the limiting plates 21 can be adjusted within a small range. The threaded connection facilitates disassembly later. When the limiting plates 21 or other components are damaged, it is not necessary to replace the entire profile, reducing maintenance costs.

[0040] Considering that traditional sealing strips have a single installation method and cannot adapt to the deformation caused by thermal expansion and contraction of the profile, resulting in sealing failure, an installation groove 25 is fixedly connected to one side of the sealing strip 24. The installation groove 25 is engaged with the inside of the installation strip 26 on the lower side of the limiting plate 21. The sealing strip 24 is engaged with the installation strip 26 through the installation groove 25, and can adaptively fit with the adjustment of the limiting plate 21 to maintain sealing pressure. At the same time, the engaging structure makes it easy to replace the sealing strip 24 and improves maintenance convenience.

[0041] To improve the aesthetics and structural strength of the aluminum profile during use, an insert strip 3 is provided on one side of the profile frame 1. Dovetail grooves 31 are symmetrically arranged at both ends of the insert strip 3. Dovetail strips 32 are symmetrically fixedly connected to the upper and lower ends inside the profile frame 1. The dovetail strips 32 engage with the inside of the dovetail grooves 31. After the limiting plate 21 is adjusted, the insert strip 3 is pushed in and engaged along the dovetail strips 32 of the profile frame 1, improving installation efficiency. The bidirectional bolts 22 and unidirectional bolts 23 are placed inside the profile frame 1, improving the aesthetics of the aluminum profile while ensuring its structural strength. The connection method is simple, facilitating later disassembly and maintenance, and improving the convenience of maintaining the aluminum profile. The tight engagement of the dovetail grooves 31 and dovetail strips 32 reduces gaps at the joint. Adding a sealing strip at the engagement point (such as a sealing strip on the edge of the insert strip) can further improve waterproof and dustproof performance.

[0042] Considering that the connection points of traditional profile frames 1 are weak and easily deformed under wind pressure or self-weight loads, affecting the service life of doors and windows, a connecting strip 4 is used to interlock between the two profile frames 1. Several reinforcing plates 41 are fixedly connected inside the connecting strip 4. The connecting strip 4 is fixed to the profile frames 1 on both sides through the interlocking structure. At the same time, the connecting strip 4 restricts the axial and radial displacement of the profile frames 1, ensuring the overall straightness and flatness of the upper frame after splicing. The reinforcing plates 41 are regularly distributed along the inside of the connecting strip 4, which can form a "rigid support skeleton" at the splicing point of the profile frames 1, effectively dispersing the bending moment and shear force generated by external forces, enhancing the overall rigidity, and dispersing the load.

[0043] In summary, the working principle of this solution is as follows:

[0044] Two symmetrical cavities 11 are arranged inside the frame 1 to provide installation space for the adjustment assembly 2. The limiting plates 21 in the adjustment assembly are connected by bidirectional bolts 22. When the bidirectional bolts 22 are rotated, due to their forward and reverse thread design, they can synchronously drive the limiting plates 21 on both sides to move relative to or away from each other, thereby flexibly adjusting the distance between the two limiting plates 21. This design can adapt to door and window sashes of different thicknesses. There is no need to customize the profiles in advance during installation. On-site adaptation can be completed by adjusting the bidirectional bolts 22, which effectively solves the problem of poor compatibility of traditional fixed-specification profiles. At the same time, the one-way bolts 23 threaded on the limiting plates 21 can make single-point fine adjustments and reinforcements to the position of the limiting plates 21, ensuring that they remain stable during the opening and closing of doors and windows. The sealing strip 24 on one side of the limiting plate 21 is engaged with the mounting strip 26 through the mounting groove 25. It is squeezed or released synchronously with the movement of the limiting plate 21, dynamically adjusting the sealing pressure to ensure that the doors and windows maintain good airtight performance under different working conditions.

[0045] The dovetail grooves 31 at both ends of the insert 3 tightly engage with the dovetail strips 32 inside the profile frame, utilizing the hook characteristics of the dovetail structure to achieve rapid installation and high-strength connection. The mechanical locking effect formed after engagement effectively resists external forces such as wind pressure and vibration, preventing the insert 3 from falling off. The two profile frames 1 are connected by a connecting strip 4, and the reinforcing plate 41 inside the connecting strip 4 further enhances the structural strength of the splice. The connecting strip 4 distributes the load on the door and window, reduces the risk of deformation at the profile splice, and ensures high precision and stability after splicing multiple profile sections.

[0046] This aluminum profile structure achieves size adaptation through adjustable components, completes quick connection using insert strip 3 and dovetail structure, and enhances overall stability with connecting strip 4 and reinforcing plate 41, providing an efficient and reliable upper frame solution for doors and windows.
