Description

Technical Field

[0001] This utility model belongs to the field of building technology, specifically referring to a rainproof and water-blocking structure for the lower frame of doors and windows. Background Technology

[0002] Currently, the outer windowsills of doors and windows on the market are generally plastered with cement mortar, tiled, and painted to achieve waterproofing and aesthetics. However, over time, these door and window materials are very prone to cracking at the contact point with the windowsill. This not only leads to water seepage but also poses a risk of detachment. Even with sealant for waterproofing, cracks and peeling can still occur between the wall and the sealant over time, causing rainwater to accumulate and seep into the wall cracks. Worse still, some outer windowsills are made horizontally, or even sloped downwards, failing to create a proper drainage slope, resulting in severe rainwater accumulation and seepage. To solve the above problems, the traditional approach is to fold stainless steel plates or other metal plates into "L" or "Z" shapes, insert the "L" shaped metal plate between the bottom frame profile of the door or window and the windowsill, and cover the outside of the windowsill, or place the "Z" shaped metal plate against the outside of the bottom edge of the bottom frame profile of the door or window and cover the outside of the windowsill, and fix it to the bottom frame of the door or window with screws to achieve the functions of drainage and water diversion.

[0003] However, gaps will always exist between the metal plate and the bottom frame of doors and windows, allowing rainwater to seep in slowly. Even with sealant applied to these gaps, there is still a risk of sealant failure and cracking, leading to further water leakage. Furthermore, using sealant can easily clog the drainage holes on the outside of the bottom frame, creating even greater hazards, and the exposed screws are unsightly. Therefore, given the current market situation, it is urgent to develop a rainproof and water-blocking structure for bottom frames of doors and windows that effectively solves the problem of water accumulation on windowsills, prevents rainwater leakage, provides long-lasting protection, and is easy to install. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model proposes a rainproof and water-blocking structure for the lower frame of doors and windows.

[0005] This utility model is achieved through the following technical solution: a rainproof and water-blocking structure for the lower frame of a door or window, mainly composed of a water-blocking plate, a slot seat, and a snap-on edge with a snap-on head at one end and fixedly connected to the water-blocking plate at the other end; the slot seat is provided with an upper fixed end and a lower fixed end located below the upper fixed end; the water-blocking plate is connected to the upper fixed end through its upper edge, and the snap-on edge is connected to the lower fixed end through its snap-on head.

[0006] Furthermore, the cross-section of the card slot is C-shaped, and a gap is formed between its upper fixed end and lower fixed end.

[0007] The water baffle is composed of a fixed plate, a connecting plate, and a lower folding plate. The fixed plate is located on one side of the connecting plate and connected to one end of the connecting plate, while the lower folding plate is located on the other side of the connecting plate and connected to the other end of the connecting plate. The upper end of the fixed plate is the upper edge of the water baffle, and the lower end of the lower folding plate is the lower edge of the water baffle.

[0008] The upper fixed end is an arc-shaped outer edge, and the upper edge is an arc-shaped inner edge, and the inner edge and the outer edge can be fastened together.

[0009] The upper fixed end consists of a horizontally positioned end and one or more protrusions positioned on the horizontal end and located on its lower side; the upper edge is planar and matches the protrusions.

[0010] An angle α is formed between the plane of the fixing plate and the plane of the connecting plate.

[0011] The included angle α ranges from 90° to 160°.

[0012] The lower edge of the baffle plate is lower than the plane of the bottom of the card slot.

[0013] The upper fixed end and the lower fixed end are located in the same vertical plane.

[0014] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0015] 1. This utility model has an upper fixed end and a lower fixed end on the card slot seat, and the entire card slot seat can be fixed to the side wall of the lower frame body by screws or adhesive. A connector matching the upper fixed end is provided at the upper edge of the baffle plate. Therefore, the baffle plate can be fixed to the card slot seat by the fastening connection between its connector and the upper fixed end. At the same time, this utility model also has an integrally formed buckle edge on the baffle plate, and the buckle edge has a buckle head. The buckle head can be fastened to the lower fixed end. Therefore, the above structure can form a stable triangle between the baffle plate, the buckle edge and the card slot seat, which can significantly increase its stability.

[0016] 2. The lower edge of the water baffle of this utility model is lower than the bottom plane of the card slot seat or the lower frame body, thus effectively preventing rainwater from entering the bottom of the door and window frame.

[0017] 3. This utility model guides the flow of rainwater through the physical structure of the water-blocking plate, rather than relying on chemical waterproofing methods such as sealant to achieve the purpose of waterproofing. Therefore, it can reduce the dependence on auxiliary waterproofing methods such as sealant and significantly improve the reliability of waterproofing.

[0018] 4. This utility model ingeniously utilizes a snap-fit ​​structure to fix the water baffle to the slot seat, achieving a stable connection without screws. It is not only convenient and quick to install and aesthetically pleasing, but also significantly enhances the grade of doors and windows. Attached Figure Description

Detailed Implementation

[0023] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0024] Example 1

[0025] like Figure 1 As shown, the rainproof and water-blocking structure of the lower frame of the door and window described in this embodiment mainly consists of a water-blocking plate 2, a slot seat 3, and a snap-on edge 5 with a snap-on head 51 at one end and fixedly connected to the water-blocking plate 2 at the other end. The slot seat 3 is fixed to the side wall of the lower frame body 1 by screws or adhesive to ensure that the slot seat 3 can be tightly fixed to the lower frame body 1.

[0026] The card slot 3 has an upper fixed end 31 at its upper end and a lower fixed end 32 at its lower end, meaning the lower fixed end 32 is located below the upper fixed end 31. A gap 33 is formed between the upper fixed end 31 and the lower fixed end 32, and the entire card slot 3 has a cavity inside, making the entire card slot 3 C-shaped.

[0027] One end of the snap-fit ​​edge 5 is provided with a snap-fit ​​head 51, and the other end is fixedly connected to the baffle plate 2. The upper edge 4 of the baffle plate 2 can be interlocked with the upper fixed end 31, and its specific structure is as follows. Figure 1 and Figure 2As shown, the upper fixed end 31 is an arc-shaped outer edge, and the upper edge 4 is an arc-shaped inner edge, which can be interlocked with each other. Depending on the actual situation, the upper fixed end 31 and the upper edge 4 can also be other structural shapes, as long as the upper fixed end 31 and the upper edge 4 can be interlocked or connected to each other for fixation.

[0028] In this embodiment, the water baffle 2 is a flat plate, and its structure is as follows: Figure 2 As shown. At this time, the baffle plate 2 needs to be set at an angle, and the buckle head 51 of the buckle edge 5 is engaged or connected with the lower fixed end 32, while the other end of the buckle edge 5 is fixed to the baffle plate 2. The specific shape of the plate is determined according to the actual needs of the user, and can be rectangular, elongated, elliptical or semi-circular, etc.

[0029] After installation using the above structure, the baffle 2 can be fixed to the slot seat 3 by engaging its upper edge 4 with the upper fixed end 31. The snap-fit ​​head 51 of the snap-fit ​​edge 5 can engage with the lower fixed end 32. Therefore, the above structure can form a stable triangle between the baffle 2, the snap-fit ​​edge 5, and the slot seat 3. Since triangles have strong stability, the baffle 2 in this embodiment can, under its own weight, tightly engage the snap-fit ​​head 51 of the snap-fit ​​edge 5 with the lower fixed end 32, thereby ensuring the stability of the entire baffle 2 after installation.

[0030] Example 2

[0031] The difference between this embodiment and embodiment 1 is the structure of the water baffle 2. In this embodiment, the water baffle 2 consists of three parts: a fixing plate 21, a connecting plate 22, and a lower folding plate 23, as shown in the figure. Figure 1 and Figure 3 As shown, the fixing plate 21 and the lower folding plate 23 are located on both sides of the connecting plate 22, with one end of the fixing plate 21 connected to one end of the connecting plate 22, and one end of the lower folding plate 23 connected to the other end of the connecting plate 22. This allows the fixing plate 21, connecting plate 22, and lower folding plate 23 to be sequentially connected to form a shape resembling a "Z". At this time, the connecting plate 22 needs to be tilted, with the snap-fit ​​head 51 of the snap-fit ​​edge 5 engaging with the lower fixing end 32, while the other end of the snap-fit ​​edge 5 is fixedly integrated with the connecting plate 22.

[0032] In this structure, the upper end of the fixing plate 21 is the upper edge 4 of the water baffle 2, and the lower end of the lower folding plate 23 is the lower edge of the water baffle 2.

[0033] Regardless of the shape or configuration of the baffle 2, the lower edge of the baffle 2 must be lower than the bottom plane of the lower frame body 1, thereby ensuring that the baffle 2 can cover the entire lower part of the lower frame body 1, preventing the gap between the lower frame body 1 and the outer windowsill of the door and window from being exposed, and further preventing external rainwater from seeping in.

[0034] When the water baffle 2 is composed of three parts: a fixed plate 21, a connecting plate 22, and a lower folding plate 23, an angle α is formed between the plane of the fixed plate 21 and the plane of the connecting plate 22 to facilitate drainage. The value of the angle α can be set arbitrarily according to the site conditions, and its value range is generally between 90°≤α≤160°.

[0035] After installation using the above structure, since the slot seat 3 is integrally fixed to the lower frame body 1, and the buckle edge 5 is integrally fixed to the connecting plate 22, when the buckle head 51 of the buckle edge 5 is fastened to the lower fixed end 32, the upper edge of the fixed plate 21, the fixed connection point between the buckle edge 5 and the connecting plate 22, and the fixed connection point between the buckle head 51 and the lower fixed end 32 form the three vertices of a triangle. Because triangles have strong stability, the baffle plate 2 in this embodiment can, under its own weight, tightly fasten the buckle head 51 of the buckle edge 5 to the slot seat 3, thereby ensuring the stability of the entire baffle plate 2 after installation.

[0036] In this embodiment, the lower fixed end 32 and the buckle head 51 can be implemented in any shape, as long as they can achieve the purpose of fastening without separation.

[0037] Example 3

[0038] The difference between this embodiment and Embodiments 1 and 2 is that the structure of the upper fixed end 31 is different. For example... Figure 2 As shown, the upper fixed end 31 is composed of a horizontal end 311 horizontally disposed at the upper end of the slot seat 3, and one or more protrusions 312 disposed on the horizontal end 311 and located on its lower side. At this time, there will be one or more protrusion grooves 313 between two adjacent protrusions 312.

[0039] In this embodiment, the upper edge 4 of the baffle plate 2 is disposed inside the protrusion groove 313, and the upper edge 4 of the baffle plate 2 is connected to the protrusion 312 in a contact-fixed manner. Contact-fixing refers to the connection between two components through mutual contact without fixation, allowing for easy separation of the two components at any time. When using contact-fixing, factors such as the direction of force and coefficient of friction between the two connecting components need to be considered. Therefore, the rationality and ingenuity of the overall structural design are necessary when using contact-fixing.

[0040] When there are two or more protruding grooves 313, the installer can select the appropriate protruding groove 313 according to actual needs, so that the upper position of the baffle plate 2 can be flexible.

[0041] In order to minimize the noise generated when rainwater drips onto the baffle 2, the baffle 2 in all the above embodiments can be made into one or more cavity structures, and the cavity structure is filled with foaming agent to increase its overall strength and sound insulation performance.

[0042] As described above, this utility model can be implemented quite well.
