Description

Technical Field

[0001] This utility model relates to the field of door and window profile technology, and in particular to a thermally broken aluminum mullion with a flow-guiding concealed drainage structure. Background Technology

[0002] Thermally broken aluminum is the most commonly used profile in door and window systems today. It has excellent thermal insulation and water tightness. The mullion is used to reinforce and divide the overall door and window. In the existing technology, for example, the utility model patent: A Concealed Drainage Structure for an Aluminum Alloy Inward Opening Window (Announcement No.: CN211692193U) discloses a mullion with a concealed drainage structure. Its concealed drainage function is mainly achieved by water inlet and drain outlet that are connected to each other on the mullion. However, in actual use, the above-mentioned concealed drainage structure will produce water residue inside the mullion. The residual water will cause corrosion to the profile and affect the performance and service life of the profile. The holes opened on the mullion will also have a certain impact on the strength of the profile.

[0003] To address the aforementioned problems, this utility model provides improvements. Utility Model Content

[0004] This invention proposes a thermally broken aluminum mullion with a flow-guiding concealed drainage structure, which solves the above-mentioned problems existing in the use of the prior art.

[0005] The technical solution of this utility model is implemented as follows:

[0006] A thermally broken aluminum mullion with a flow-guiding concealed drainage structure includes an outer frame, a middle frame, and an inner frame. The outer frame is composed of a connecting frame and a baffle, and also includes a flow guide. The connecting frame has an installation port that runs vertically through the connecting frame. The upper flow guide portion of the flow guide is fixedly connected to the connecting frame and located inside the installation port. The lower drainage portion of the flow guide is attached to the inner wall of the baffle. A flow guide cavity is formed inside the flow guide portion. An inlet is formed at the upper end of the flow guide cavity and located inside the upper port of the installation port. A drainage cavity communicating with the flow guide cavity is formed inside the drainage portion. A drainage outlet is formed at the lower end of the drainage cavity.

[0007] Preferably, the flow guide is composed of a box with an opening at the top and a cover plate covering the opening at the top of the box. Several bolts pass through the cover plate and are screwed onto the box to achieve a fixed connection between the flow guide and the connecting frame.

[0008] Preferably, the upper end of the cover plate forms a limiting boss that matches the upper port of the mounting port and passes through the upper port of the mounting port, and the lower end of the cover plate forms a limiting ring that matches the upper opening of the box and passes through the upper opening of the box.

[0009] Preferably, a sealing gasket layer is provided between the upper end face of the cover plate and the inner wall of the connecting frame.

[0010] Preferably, the bottom wall of the guide cavity is inclined and the lower end of the bottom wall of the guide cavity is connected to the drainage cavity.

[0011] Preferably, the inlet has a plurality of inlet partitions and the outlet has a plurality of outlet partitions.

[0012] Preferably, a water-proof strip is formed at the upper end of the connecting frame, located inside the upper port of the mounting port.

[0013] In summary, the beneficial effects of this utility model are as follows: rainwater that seeps into the thermally broken aluminum mullion passes through the inlet, guide cavity, drainage cavity, and drain outlet sequentially before being discharged, thus achieving the drainage function. Because the drain outlet, guide cavity, drainage cavity, and drain outlet are distributed vertically from top to bottom, the rainwater discharge path is longitudinally located on the outside of the window glass, ensuring that rainwater seeping into the thermally broken aluminum mullion can be discharged quickly and smoothly, preventing rainwater from remaining inside the thermally broken aluminum mullion. Furthermore, the drainage channel is located within the guide component, reducing direct contact between rainwater and the outer frame during drainage, thereby... This design effectively prevents rainwater from corroding the thermally broken aluminum mullions during drainage, ensuring their performance and extending their service life. Furthermore, the drainage section is located inside the connecting frame, with the drainage section flush against the edge, concealing the drainage component on the outer frame. This prevents interference with the frame's structure and thus avoids affecting the overall structure of the thermally broken aluminum mullions, maintaining their aesthetic appeal. Additionally, the drainage component fills the installation opening, providing support to the outer frame and reducing the impact of the installation opening on the strength of the thermally broken aluminum mullions.

[0021] The following will refer to the appendix in the embodiments of this utility model. Figure 1-5 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] As shown in the figure, a thermally broken aluminum mullion with a flow-guiding concealed drainage structure includes an outer frame 1, a middle frame 2, an inner frame 3, and a flow guide 4. The outer frame 1 is composed of a connecting frame 11 and a retaining edge 12. The connecting frame 11 has an installation port 13 that runs vertically through the connecting frame 11. The upper flow guide part 41 of the flow guide 4 is fixedly connected to the connecting frame 11 and located inside the installation port 13. The lower drainage part 44 of the flow guide 4 is attached to the inner wall of the retaining edge 12. A flow guide cavity 42 is formed inside the flow guide part 41. An inlet 43 is formed at the upper end of the flow guide cavity 42 and located inside the upper port of the installation port 13. A drainage cavity 45 communicating with the flow guide cavity 42 is formed inside the drainage cavity 44. A drainage outlet 46 is formed at the lower end of the drainage cavity 45.

[0023] Specifically, the structure of the flow guide 4 fixedly connected to the connecting frame 11 is as follows: the flow guide 4 is composed of a box 47 with an upper opening and a cover plate 48 covering the upper opening of the box 47. Several bolts are threaded through the cover plate 48 and screwed onto the box 47 to realize the fixed connection between the flow guide 4 and the connecting frame 11. The flow guide part 41 and the drainage part 44 are formed on the box 47, the water inlet 43 is formed on the cover plate 48, the flow guide cavity 42 is formed between the cover plate 48 and the box 47, and the drainage cavity 45 is formed inside the box 47. The above structure facilitates the formation of the flow guide cavity 42 and the drainage cavity 45 by separating the flow guide 4 into the box 47 and the cover plate 48. The fixed connection with the connecting frame 11 by bolts also facilitates the disassembly and assembly of the flow guide 4.

[0024] In the above structure, such as Figure 5As shown, when this type of thermally broken aluminum mullion is applied to a window and door system, the retaining edge 12 is located on the outside of the window glass. Rainwater from outside seeps into the thermally broken aluminum mullion through the gap between the retaining edge 12 and the window glass, falling onto the connecting frame 11. The rainwater falling onto the connecting frame 11 flows into the guide cavity 42 through the inlet 43. The rainwater flowing into the guide cavity 42 then flows into the drainage cavity 45 and exits through the drain outlet 46, thus draining the rainwater from the thermally broken aluminum mullion and achieving the drainage function. During this drainage process, the drain outlet 46, guide cavity 42, drainage cavity 45, and drain outlet 46 are distributed vertically from top to bottom, ensuring that the rainwater drainage path is vertically located on the outside of the window glass, guaranteeing that the rainwater seeping into the thermally broken aluminum mullion can be drained quickly and smoothly. To prevent rainwater from remaining inside the thermally broken aluminum mullion, and with the drainage channel located inside the guide 4, direct contact between rainwater and the outer frame 1 is reduced during drainage, effectively preventing corrosion of the thermally broken aluminum mullion by rainwater during drainage, ensuring the performance of the thermally broken aluminum mullion and extending its service life. Furthermore, the guide 41 is located inside the connecting frame 11, and the drainage part 44 is set close to the baffle 12, so that the guide 4 is hidden on the outer frame 1 and will not interfere with or affect the structure of the outer frame 1, thus not interfering with or affecting the overall structure of the thermally broken aluminum mullion, ensuring the aesthetics of the thermally broken aluminum mullion. Moreover, the guide 4 is set inside the installation opening 13 and fills the installation opening 13, providing a certain support to the outer frame 1, reducing the impact of opening the installation opening 13 on the strength of the thermally broken aluminum mullion.

[0025] Furthermore, based on the above structure, a limiting boss 481 is formed at the upper end of the cover plate 48, which matches the upper port of the mounting port 13 and penetrates into the upper port of the mounting port 13. A limiting protrusion 482 is formed at the lower end of the cover plate 48, which matches the upper opening of the housing 47 and penetrates into the upper opening of the housing 47. The limiting boss 481 limits the displacement of the cover plate 48 relative to the connecting frame 11, thereby strengthening the stability of the guide member 4 fixedly connected to the connecting frame 11. The limiting protrusion 482 limits the displacement of the cover plate 48 relative to the housing 47, thereby strengthening the stability of the cover plate 48 when it is assembled with the housing 47, and thus strengthening the overall strength of the guide member 4.

[0026] In addition, based on the above structure, a sealing gasket 49 is provided between the upper end face of the cover plate 48 and the inner wall of the connecting frame 11. The sealing gasket 49 enhances the sealing between the guide 4 and the connecting frame 11, preventing rainwater from entering the interior of the connecting frame 11.

[0027] Furthermore, based on the above structure, the bottom wall of the guide cavity 42 is inclined and the lower end of the bottom wall of the guide cavity 42 is connected to the drainage cavity 45, so that the rainwater flowing into the guide cavity 42 flows into the drainage cavity 45 more quickly through the guiding effect of the inclined bottom wall, thereby accelerating the drainage speed.

[0028] Furthermore, based on the above structure, several inlet partitions 431 are formed inside the inlet 43, and several drainage partitions 461 are formed inside the outlet 46. The supporting effect of the inlet partitions 431 and the drainage partitions 461 strengthens the strength of the inlet 43 and the outlet 46, thereby strengthening the overall strength of the guide member 4. The inlet partitions 431 and the outlet partitions divide the inlet 43 and the outlet 46 into several smaller units, thereby preventing larger debris from entering the guide member 4 and causing blockage of the guide cavity 42 and the drainage cavity 45, thus ensuring the drainage performance of the guide member 4.

[0029] In addition, based on the above structure, a water-proof strip 14 is formed at the upper end of the connecting frame, located inside the upper port of the mounting port 13. The water-proof strip 14 acts as a barrier against rainwater falling onto the connecting middle frame 2, preventing rainwater from flowing towards the middle frame 2 and intruding inward, so that the rainwater accumulates on the connecting middle frame 2 and is discharged through the guide 4.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
