Abstract
Description
Technical Field
[0001] This utility model relates to the field of waterproofing technology for window sills, and in particular to a waterproof building structure for window sills. Background Technology
[0002] The main body of the windowsill refers to the flat part that supports the window frame. The design of the main body of the windowsill makes it more aesthetically pleasing. The function of the main body of the windowsill is to drain rainwater running along the window surface, preventing it from seeping into the wall and into the room through window gaps. It also prevents rainwater from staining the exterior wall. During heavy rain, wind forces can cause rainwater to blow obliquely towards the window, and the main body of the windowsill cannot completely prevent rainwater from entering the room through window gaps. Therefore, the main body of the windowsill needs to be waterproofed. Usually, a rain shelter is installed on the wall above the main body of the windowsill. However, in sunny weather, the rain shelter can block sunlight, affecting the amount of light entering the main body of the windowsill. Utility Model Content
[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a waterproof building structure for window sills.
[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a waterproof building structure for a window sill, including a wall, a window installed inside the wall, a window sill body at the bottom of the window, a device groove inside the window sill body, a shielding component inside the device groove, the shielding component including first sliding grooves on both sides of the device groove, first sliding blocks slidably connected inside the first sliding grooves, a shielding plate fixedly connected between the two first sliding blocks, a fixing opening at the bottom of the shielding plate, first rotating rods rotatably connected to both sides of the bottom of the device groove, and a support frame fixedly connected between the two first rotating rods.
[0005] As a preferred technical solution of this utility model, the surface of the window is provided with a top-out assembly. The top-out assembly includes a second sliding groove opened on both sides of the window. The second sliding groove is connected to the first sliding groove. A top rod is fixedly connected inside the second sliding groove. A second slider is slidably connected inside the second sliding groove. The end of the second slider away from the second sliding groove is fixedly connected to a baffle plate.
[0006] As a preferred technical solution of this utility model, the surface of the wall is provided with a rainproof component. The rainproof component includes a concave fixing plate disposed on the surface of the wall. A second rotating rod is rotatably connected to both sides of the concave fixing plate. An extension plate is fixedly connected between the two second rotating rods. A spring groove is provided on the side of the extension plate away from the second rotating rods. A first spring is fixedly connected inside the spring groove.
[0007] As a preferred technical solution of this utility model, the end of the first spring away from the second rotating rod is fixedly connected to a limiting block, and the rainproof assembly includes a limiting groove opened inside the wall and communicating with the second sliding groove.
[0008] As a preferred embodiment of this utility model, a second spring is fixedly connected to the bottom of the concave fixing plate. The end of the second spring away from the concave fixing plate is fixedly connected to the extension plate. A limit line is fixedly connected to the end of the extension plate away from the second rotating rod. The end of the limit line away from the extension plate passes through the limit groove and is fixedly connected to the baffle plate.
[0009] Compared with the prior art, the beneficial effects that this utility model can achieve are:
[0010] This utility model, through the setting of wall, window, window sill body, device groove and shielding component, allows the shielding plate to be raised by pulling the handle when it rains, through the cooperation of the first sliding groove and the first slider. The support frame is rotated by the first rotating rod and inserted into the fixing hole to fix the shielding plate. The shielding plate blocks the rainwater blown obliquely towards the window sill body by the wind, and prevents the rainwater from accumulating on the window sill body and seeping into the room along the window gap.
[0011] This invention, through the design of a wall, window, top-mounted assembly, and rainproof assembly, allows the limiting block to be squeezed out of the limiting groove by the rising top rod when the weather is sunny. This causes the second spring to push the extension plate to flip and block rainwater. When the weather is sunny, the limiting line pulls the extension plate, causing it to move into the concave fixed plate. The first spring then pushes the limiting block into the limiting groove, thus limiting the extension plate and preventing it from blocking sunlight. This allows the device to be used according to different weather conditions. Attached Figure Description

[0023] Example: This utility model provides, for example... Figure 1 , Figure 2 , Figure 3 and Figure 6 The illustrated waterproof window sill structure includes a wall 1, a window 11 installed inside the wall 1, a window sill body 12 at the bottom of the window 11, a device groove 13 inside the window sill body 12, a shielding component 2 inside the device groove 13, the shielding component 2 including first sliding grooves 21 on both sides of the device groove 13, first sliding blocks 22 slidably connected inside the first sliding grooves 21, a shielding plate 23 fixedly connected between the two first sliding blocks 22, a fixing opening 24 at the bottom of the shielding plate 23, first rotating rods 25 rotatably connected to both sides of the bottom of the device groove 13, and a support frame 26 fixedly connected between the two first rotating rods 25.
[0024] refer to Figure 1 , Figure 2 , Figure 3 and Figure 6As shown, during heavy rain, the shield 23 is raised by the cooperation of the first sliding groove 21 and the first slider 22. At the same time, the support frame 26 is pulled to rotate by the second rotating rod 42, so that the support frame 26 is inserted into the fixing hole 24 to fix the shield 23. The shield 23, the window sill body 12 and the window 11 form a triangle to block the rain.
[0025] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a top-out assembly 3 is provided on the surface of window 11. The top-out assembly 3 includes second sliding grooves 31 on both sides of window 11, which are connected to first sliding grooves 21. A top rod 32 is fixedly connected inside the second sliding groove 31, and a second slider 33 is slidably connected inside the second sliding groove 31. The end of the second slider 33 away from the second sliding groove 31 is fixedly connected to a baffle plate 23. A rainproof assembly 4 is provided on the surface of wall 1. The rainproof assembly 4 includes a concave fixing plate 41 on the surface of wall 1. Second rotating rods 42 are rotatably connected to both sides of the concave fixing plate 41. An extension plate 43 is fixedly connected between the two second rotating rods 42. A spring groove 44 is provided on the side of the wall 1 away from the second rotating rod 42. A first spring 45 is fixedly connected inside the spring groove 44. A limit block 46 is fixedly connected to the end of the first spring 45 away from the second rotating rod 42. The rainproof assembly 4 includes a limit groove 47 that is opened inside the wall 1 and communicates with the second sliding groove 31. A second spring 48 is fixedly connected to the bottom of the concave fixing plate 41. The end of the second spring 48 away from the concave fixing plate 41 is fixedly connected to the extension plate 43. A limit line 49 is fixedly connected to the end of the extension plate 43 away from the second rotating rod 42. The end of the limit line 49 away from the extension plate 43 passes through the limit groove 47 and is fixedly connected to the shield plate 23.
[0026] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, while the lifting plate is raised, the second slide 31 rises and presses against the top rod 32 inside the second slide 31, thus lifting it. The top rod 32 presses against the limiting block 46 through the limiting groove 47, causing the limiting block 46 to retract into the spring groove 44 via the first spring 45, thus releasing its restriction on the baffle plate 23. The baffle plate 23 is then pushed by the second spring 48 and rotated by the second rotating rod 42, causing the baffle plate 23 to flip out from inside the extension plate 43 to block rainwater. When the weather is sunny, the first rotating rod 25 rotates, causing the support frame 26 to emerge from the fixing opening 24. The part is rotated out to release the fixation of the baffle plate 23. At the same time, through the cooperation of the first sliding groove 21 and the first slider 22, the baffle plate 23 is housed inside the device groove 13. Simultaneously, the second slider 33 descends inside the second sliding groove 31. As the top rod 32 descends, the baffle plate 23 pulls the limiting line 49, which in turn pulls the extension plate 43. The extension plate 43 is rotated and flipped inside the concave fixing plate 41 by the second rotating rod 42. At the same time, the first spring 45 pushes the limiting block 46 to insert into the limiting groove 47, thus fixing the extension plate 43 inside the concave fixing plate 41.
[0027] Working principle:
[0028] Before use: Refer to Figure 1 As shown, when the weather is sunny, the shield 23 is stored inside the concave fixing plate 41 to ensure good lighting for the main body of the windowsill 12.
[0029] When using: Refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, during heavy rain, the shield 23 is raised by the cooperation of the first sliding groove 21 and the first slider 22. At the same time, the support frame 26 is pulled and rotated by the second rotating rod 42, so that the support frame 26 is inserted into the fixing port 24 to fix the shield 23. The shield 23, the window sill body 12 and the window 11 form a triangle to block the rain. While the lifting plate is raised, the second sliding groove 31 rises and squeezes the top rod 32 inside the second sliding groove 31 to lift it. The top rod 32 squeezes the limiting block 46 through the limiting groove 47, so that the limiting block 46 is retracted into the spring groove 44 by the first spring 45 and cancels the limiting of the shield 23. The shield 23 is pushed by the second spring 48 and the second rotating rod 42 rotates, so that the shield 23 flips out from inside the extension plate 43 to block the rain.
[0030] After use: Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, when the weather is clear, the first rotating rod 25 rotates, causing the support frame 26 to rotate out of the fixed opening 24 and cancel the fixation of the baffle plate 23. At the same time, through the cooperation of the first sliding groove 21 and the first slider 22, the baffle plate 23 is stored in the device groove 13. Simultaneously, the second slider 33 descends inside the second sliding groove 31, causing the top rod 32 to descend. At the same time, the baffle plate 23 pulls the limiting line 49, causing the limiting line 49 to pull the extension plate 43. The extension plate 43 is rotated and flipped into the concave fixed plate 41 by the second rotating rod 42. At the same time, the first spring 45 pushes the limiting block 46 to insert into the limiting groove 47, fixing the extension plate 43 inside the concave fixed plate 41.
