Description

Technical Field

[0001] The utility model relates to the technical field of building door and window assembly, and particularly relates to a window profile corner fitting with expandable wedge blocks. Background Art

[0002] During the assembly process of window frames, corner fittings are widely used. However, there are many problems in the prior art regarding the tight fit and automatic leveling between the corner fittings and window frame profiles. The traditional corner fitting process mainly includes the following steps:

[0003] 1. Inserting the corner fitting into the window profile: Usually, an integral or split corner fitting is inserted into the window profile. However, in order to facilitate insertion, the integral or split corner fitting does not fully match the inner cavity of the window profile, resulting in the need for additional adjustment steps after corner assembly.

[0004] 2. Tightening the corner: The inserted corner fitting is tightened on the window frame through a corner fitting device. However, due to process limitations, the corners of the window frame profile are often uneven after corner fitting, and manual knocking is required to achieve a flat effect. This process is not only time-consuming and laborious but also prone to errors due to manual operation, resulting in damage to the window frame profile and the corner fitting.

[0005] 3. Injecting glue for fixation: In order to fill the gap between the corner fitting and the window profile, glue is injected to ensure a tight fit. However, after injecting the glue, a C-clamp needs to be used for static placement to prevent the corner fitting and the window frame profile from being misaligned during the glue solidification process. This step occupies a large amount of production space and time, significantly reducing production efficiency.

[0006] 4. Static placement and handling: After the glue solidifies, the C-clamp needs to be removed for handling. During the handling process, due to the small gap between the corner fitting and the window frame profile, misalignment is likely to occur, affecting product quality.

[0007] To solve this problem, refer to the utility model patent disclosed in "A New Type of Window and Door Corner Fitting with a Leveling Function" with the application number 202123186785.0. Although corner fitting fixings are used, most of these leveling corner fittings rely on the deformation of the overall structure or external forces, making it difficult to ensure the accuracy and consistency of each operation.

[0008] Therefore, how to achieve a tight fit and automatic leveling between the corner fitting and the window frame profile through innovative structural design, and avoid manual adjustment and glue injection static placement steps, has become the technical problem to be solved by the present utility model. Summary of the Utility Model

[0009] The technical problem solved by the present utility model is to provide a window profile corner fitting with an expandable wedge block to address the defects in the above-mentioned prior art, namely, the inconsistency between the leveling and tight fitting of the corner fitting and the low production efficiency as proposed in the background art.

[0010] To solve the above technical problems, the technical solution adopted by the present utility model is as follows:

[0011] A window profile corner fitting with an expandable wedge block, comprising an upper corner fitting component, a lower corner fitting component, and an intermediate plastic part;

[0012] The intermediate plastic part is arranged between the upper corner fitting component and the lower corner fitting component. The intermediate plastic part includes an impact avoidance cavity. The wedge block structure includes a small thickness part and a large thickness part. The small thickness part of the wedge block structure is connected to the impact avoidance cavity of the intermediate plastic part through a connecting rod;

[0013] The wedge block structure is arranged at the corner position of the intermediate plastic part and can be pressed into the impact avoidance cavity between the upper corner fitting component and the lower corner fitting component during the corner fitting process;

[0014] The wedge block structure includes a state before the corner fitting and a state after the wedge block structure is corner - fitted;

[0015] When the wedge block structure is in the state before the corner fitting, the small thickness part of the wedge block structure is located between the upper corner fitting component and the lower corner fitting component;

[0016] After the wedge block structure is corner - fitted and in the state after the wedge block structure is corner - fitted, the large thickness part of the wedge block structure is located between the upper corner fitting component and the lower corner fitting component, causing the upper corner fitting component and the lower corner fitting component to relatively expand due to the pressing - in of the large thickness part of the wedge block structure, thereby enabling the upper corner fitting component and the lower corner fitting component to be tightly clamped and limited in cooperation with the window frame profile.

[0017] As a further scheme of the present utility model, the intermediate plastic part and the wedge block structure are of an integrally formed structure.

[0018] As a further scheme of the present utility model, the material of the wedge block structure is selected as a plastic with certain elasticity, including but not limited to polyurethane or thermoplastic elastomer to ensure that the wedge block structure can provide sufficient expansion force between the upper corner fitting component and the lower corner fitting component after the corner fitting.

[0019] As a further scheme of the present utility model, the outer surfaces of the upper corner fitting component and the lower corner fitting component are respectively provided with a plurality of card slots, and the card slots are used to cooperate with the inner wall of the window frame profile to achieve tight clamping of the corner fitting and the window frame profile.

[0020] As a further solution of the utility model, a plurality of reinforcing ribs are further provided on the outer surfaces of the upper corner code component and the lower corner code component, and the reinforcing ribs extend along the length direction of the corner code component to enhance the structural strength of the corner code component and prevent deformation during the corner hitting process.

[0021] As a further solution of the utility model, there is an inclined surface transition region between the small thickness part and the large thickness part of the wedge block structure.

[0022] As a further solution of the utility model, impact avoidance concave cavities are respectively arranged on one outer side part and the other outer side part of the middle plastic part during the corner hitting.

[0023] As a further solution of the utility model, the connecting rod is an inclined rod.

[0024] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0025] 1. Innovative unfolding method: During the corner hitting process, the wedge block structure is pressed into the gap between the upper corner code component and the lower corner code component to realize the relative unfolding of the corner code component, so that the corner code component is tightly clamped with the window frame profile. This design significantly improves the connection strength between the corner code and the window frame, and avoids the cumbersome steps of manually knocking the flat corner code in the traditional process.

[0026] 2. Efficient installation process: The corner code design of this application simplifies the installation steps. After the wedge block structure is corner hit, the corner code can automatically expand and tightly fit with the window frame profile, eliminating the need for re-adjustment due to corner code misalignment, thus greatly improving the assembly efficiency, saving labor and time costs, and avoiding manually flattening the corners.

[0027] 3. Excellent stability: Under the action of the wedge block structure, the upper corner code component and the lower corner code component can realize relative unfolding and tightly clamp the window frame profile, ensuring that the corner code will not be displaced or misaligned during use. At the same time, the installed corner code forms a firm connection with the window frame profile, without the need for additional fixtures to fix, ensuring the stability and durability of the structure.

[0028] 4. Avoiding misalignment and displacement: During the assembly process, due to the pressing action of the wedge block structure, the upper and lower corner code components can tightly fit the window frame profile. This can avoid displacement and misalignment problems caused by gaps during handling and installation, ensuring the assembly accuracy and improving the product quality.

[0029] 5. Optimizing the use effect of glue: After corner hitting, due to the tight fit between the corner code and the window frame profile, the subsequent glue injection process can be more uniform and efficient. After the glue is initially cured, there is no need for external fixtures to fix, thus simplifying the process flow and ensuring the firmness and sealing performance after glue injection.

[0030] 6. Automatic leveling function: The corner code design of this application realizes the automatic leveling function by pressing the wedge block structure, enabling the corner code to automatically adjust to the optimal position during the assembly process, ensuring the flatness of the window frame corner, and further improving the assembly quality and aesthetics.

[0040] Please refer to Figure 1 —4. In the embodiments of the present utility model, a window profile corner code with an expandable wedge block includes an upper corner code component 1, a lower corner code component 2, and a middle plastic part 3;

[0052] Embodiment 1:

[0053] During the assembly process of modern window frames, the installation of corner codes is a crucial step to ensure the stability and sealing performance of the window frames. Traditional methods for installing window frame corner codes mainly rely on manual hammering and mechanical pressing, which not only increases the operational complexity but also easily leads to problems such as corner code misalignment and insecure installation. The adjustable leveling impact corner code design of the present utility model effectively solves these problems. The following is its implementation method in specific application scenarios.

[0054] In the assembly workshop of a certain window manufacturing factory, workers need to connect the four corners of an aluminum alloy window frame. The traditional method requires workers to use hammers or other tools to manually hammer the corner codes to make them tightly combined with the window frame profiles. However, this method is not only time-consuming and laborious but also easily causes the offset of the corner code positions and damage to the window frame profiles, affecting the quality and production efficiency of the final product.

[0055] To improve the assembly efficiency and product quality, this manufacturing factory decides to adopt the adjustable leveling impact corner code of the present utility model. The specific implementation steps are as follows:

[0056] 1. Prepare the corner code components: Provide the upper corner code part 1, the lower corner code part 2, and the middle plastic part 3. The middle plastic part 3 is arranged between the upper corner code part 1 and the lower corner code part 2. A wedge block structure 6 is arranged on the middle plastic part 3. The wedge block structure 6 includes a small thickness part 4 and a large thickness part 5, and the middle plastic part 3 is connected through the small thickness part 4.

[0057] 2. Insert the corner code: Assemble the upper corner code part 1, the lower corner code part 2, and the middle plastic part 3 together and insert them into the corner of the window frame profile. At this time, the small thickness part 4 of the wedge block structure 6 is located in the gap between the upper corner code part 1 and the lower corner code part 2.

[0058] 3. Impact corner process: Use a specially designed corner impact device to perform the corner impact treatment on the inserted corner code window frame. During the corner impact process, the wedge block structure 6 is pressed into the impact avoidance cavity between the upper corner code part 1 and the lower corner code part 2 through the pressure of the device, so that the large thickness part 5 of the wedge block structure 6 is located between the upper corner code part 1 and the lower corner code part 2, forcing the upper corner code part 1 and the lower corner code part 2 to relatively expand and tightly engage with the window frame profile.

[0059] 4. Glue injection for fixation: After the corner code is tightly engaged with the window frame profile, perform glue injection treatment. Since the corner code has been tightly fixed through the wedge block structure 6, there is no need to use external clamps for fixation, and only need to wait for the glue to be initially cured.

[0060] 5. Final fixation: After the glue is initially cured, the window frame already has sufficient stability and sealing performance, and there is no need for further static placement and adjustment, and it can be directly packaged and stored in the warehouse.

[0061] Through the above embodiments, the adjustable leveling impact angle corner fitting of the present utility model has shown remarkable technical effects and improvements in practical applications:

[0062] 1. Improve installation efficiency: Through the design of the wedge block structure 6, the cumbersome steps of traditional manual knocking are avoided, enabling the corner fitting to automatically expand and tightly fit with the window frame profile, greatly improving the assembly efficiency.

[0063] 2. Ensure installation stability: The wedge block structure 6 provides sufficient expansion force during the impact angle process, ensuring the tight clamping between the upper corner fitting component 1 and the lower corner fitting component 2 and the window frame profile, and avoiding the problems of dislocation and displacement of the corner fitting during handling and installation.

[0064] 3. Simplify the process flow: The tight connection between the corner fitting and the window frame profile makes the gluing process more uniform and efficient, eliminating the need for using external fixtures for fixing and standing still, saving production space and time.

[0065] 4. Improve product quality: Through the automatic leveling function, the flatness of the window frame corner is ensured, improving the aesthetics and quality stability of the final product.

[0066] In summary, the adjustable leveling impact angle corner fitting of the present utility model significantly improves the window frame assembly process through innovative structural design and reasonable implementation steps, and has extremely high application value and promotion prospects.

[0067] Embodiment 2: The functions of the connecting rod and the impact avoidance cavity.

[0068] In the modern window frame assembly process, in order to further improve the installation efficiency of the corner fitting and the overall quality of the product, the present utility model provides a window profile impact angle corner fitting with a marked expandable wedge block. This article specifically introduces the functions and working principles of the connecting rod and the induction avoidance cavity, and demonstrates their application effects through specific embodiments.

[0069] The main function of the connecting rod 8 in the present utility model is to provide a basic connection, enabling the wedge block structure 6 to be stably connected to the intermediate plastic part 3. In the impact angle state of the wedge block structure 6 of the wedge block structure 6, the connecting rod 8 ensures that the small thickness part 4 of the wedge block structure 6 is located between the upper corner fitting assembly 1 and the lower corner fitting assembly 2, maintaining its initial position. After the wedge block structure 6 is impacted, the connecting rod 8 still plays a role of stable connection, ensuring that the large thickness part 5 of the wedge block structure 6 can be accurately pressed between the upper corner fitting component 1 and the lower corner fitting component 2 to achieve gap clamping.

[0070] The design of the impact avoidance cavity 7 is crucial in the present utility model. It provides the avoidance space required by the wedge block structure 6 during the corner ramming process. When pressure is applied by the corner ramming device, the small thickness part 4 of the wedge block structure 6 is pressed into the influence avoidance cavity 7 through the connecting rod 8, causing the whole of the wedge block structure 6 to move inward, and gradually transforming into the large thickness part 5 being pressed between the upper corner fitting member 1 and the lower corner fitting member 2. This ensures that the wedge block structure 6 can be smoothly engaged and provides sufficient expansion force at the final position to achieve a tight clamping of the window frame profile.

[0071] Embodiment 2: Specific application scenario

[0072] In the assembly workshop of a certain production factory, in order to further optimize the production process, the production factory adopted the adjustable leveling corner fitting of the present utility model. The following are the specific implementation steps:

[0073] 1. Prepare the corner fitting components: Provide the upper corner fitting member 1, the lower corner fitting member 2, and the intermediate member 3. A wedge block structure 6 including a small thickness part 4 and a large thickness part 5 is provided on the intermediate plastic part 3 between the upper corner fitting member 1 and the lower corner fitting member, and is connected to the intermediate plastic part 3 through the connecting rod 8.

[0074] 2. Insert the corner fitting: Assemble the upper corner fitting member 1, the lower corner fitting member 2, and the intermediate forming member 3 together and insert them into the corner of the window frame profile. At this time, the small thickness part 4 of the wedge block structure 6 is located in the gap between the upper corner fitting member 1 and the lower corner fitting member 2.

[0075] 3. Corner ramming process: Use a specially designed corner ramming device to perform corner ramming on the inserted corner fitting window frame. During the corner ramming process, the wedge block structure 6 presses upward between the upper corner fitting member 1 and the lower corner fitting member 2 through the pressure of the device. At this time, the small thickness part 4 of the wedge block structure 6 gradually transitions to the large thickness part 5, which is equivalent to the upper corner fitting member 1 and the lower corner fitting member 2 relatively spreading apart and tightly clamping with the window frame profile.

[0076] 4. Glue injection for fixation: After the corner fitting is tightly clamped with the frame profile, glue injection treatment is carried out. Since the corner fitting has achieved tight window fixation through the wedge block structure 6, there is no need to use external clamps for fixation, and only need to wait for the glue to be initially cured.

[0077] 5. Final fixation: After the glue is initially cured, the window frame already has sufficient support and sealing performance, and there is no need for further static placement and adjustment, and it can be directly packaged and stored in the warehouse.
