Description

Technical Field

[0001] This utility model relates to the field of door and window accessories technology, specifically a watertight structure for the opening and closing of doors and windows. Background Technology

[0002] The water tightness of doors and windows refers to their ability to prevent rainwater leakage when closed, under the combined action of wind and rain. It is one of the five major performance indicators of doors and windows, and together with wind pressure resistance, air tightness, thermal insulation and sound insulation, it constitutes an important standard for testing the quality of doors and windows.

[0003] Existing watertight structures for doors and windows still pose a risk of rainwater leakage in practical applications: when encountering severe weather such as heavy rain and strong winds, rainwater can easily seep in through the gaps between the two door and window frames. Especially under the action of wind pressure, water may backflow into the room along the gaps, causing damage to the decoration or dampness to the structure. To address this issue, we provide a watertight structure for the opening and closing of doors and windows. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a watertight structure for the opening and closing of doors and windows.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a watertight structure for the opening and closing of doors and windows, comprising a mounting frame, two door and window frames slidably connected inside the mounting frame, and glass embedded inside the door and window frames, with rubber frames provided between the glass and the door and window frames, a baffle fixedly connected to the bottom of the mounting frame, and a drainage mechanism provided on one side of the baffle, an inclined strip fixedly connected to the bottom of the mounting frame, and multiple water guide grooves respectively opened at the bottom of the mounting frame, a rotating plate rotatably connected inside the water guide groove, the water guide groove being located on one side of the drainage mechanism, a mounting block fixedly connected to the side wall of one of the door and window frames, and a plug-in mechanism movably connected inside the mounting block, and a fixing block fixedly connected to the bottom of the other door and window frame.

[0006] The drainage mechanism described above includes an inclined plate, a guide block, a sealing plate, and a rubber spring. The inclined plate has multiple sealing grooves inside. One end of the guide block is fixedly connected to one side of the sealing plate, and the other end of the guide block is slidably connected to the inside of the inclined plate. Both ends of the sealing plate are slidably connected to the inside of the sealing grooves, and the bottom end of the sealing plate is fixedly connected to one end of the rubber spring.

[0007] As described above, the bottom end of the inclined plate is fixedly connected to the bottom of the mounting frame, and the sealing groove is connected to the water guiding groove.

[0008] As mentioned above, the bottom end of the rubber spring is fixedly connected to the inner bottom of the mounting frame.

[0009] The aforementioned insertion mechanism includes a cam, a slide rod, and an insertion rod. The outer wall of the cam is provided with a spiral groove, and the interior of the cam is fixedly connected to the outer wall of the insertion rod. One end of the slide rod is slidably connected to the interior of the spiral groove.

[0010] As described above, the cam is located inside the mounting block, and the end of the slide bar away from the helical groove is fixedly connected to the inside of the mounting block.

[0011] As described above, one end of the insertion rod is fixedly connected to a drive wheel, and the other end of the insertion rod is inserted into the interior of the fixing block. The outer wall of the insertion rod is movably connected to the interior of the mounting block.

[0012] Compared with existing technologies, this watertight structure for door and window openings has the following advantages:

[0013] I. This utility model utilizes a drainage mechanism where the outer inclined plate directly diverts most of the rainwater to the outside. When rainwater enters the door or window frame, a baffle at the bottom of the mounting frame blocks it between the baffle and the mounting frame. Guided by the inclined plate, the rainwater preferentially enters the sealing groove. The accumulated water and gravity compress the sealing plate, causing it to move down along the guide block's trajectory and compress the rubber spring, thereby opening the water inlet of the drainage channel. The rainwater is then discharged along the inclined drainage channel. At this point, the rainwater impacts the rotating plate and diverts the rainwater to the outside of the door or window frame. The inclined design of the drainage channel effectively prevents backflow and avoids seepage into the interior, which could damage the decoration.

[0014] II. Through the plug-in mechanism, when the window is closed and locked, the rotating drive wheel drives the plug rod and cam to rotate synchronously. Since the spiral groove and the slide rod fixed in the mounting block form a sliding fit, the cam moves along the slide rod trajectory when it rotates, driving the plug rod to move axially and insert into the fixed block, thus completing the mechanical locking of the door and window. This optimizes the traditional lock that requires multiple rotations to achieve the docking of the lock handle and the lock, thereby achieving a one-time stable locking and improving the convenience of use and the reliability of the structure.

[0015] Other advantages, objectives and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be taught from the practice of this invention.

[0021] 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.

[0022] like Figure 1-4 As shown, this utility model provides a technical solution: a watertight structure for the opening and closing of doors and windows, including a mounting frame 1, two door and window frames 2 are slidably connected inside the mounting frame 1, and glass 3 is embedded inside the door and window frames 2. A rubber frame 4 is provided between the glass 3 and the door and window frames 2. A baffle 5 is fixedly connected to the bottom of the mounting frame 1, and a drainage mechanism 6 is provided on one side of the baffle 5. An inclined strip 7 is fixedly connected to the bottom of the mounting frame 1, and multiple water guide grooves 8 are respectively opened at the bottom of the mounting frame 1. A rotating plate 10 is rotatably connected inside the water guide groove 8. The water guide groove 8 is located on one side of the drainage mechanism 6. An installation block 11 is fixedly connected to the side wall of one of the door and window frames 2, and a plug-in mechanism 9 is movably connected inside the installation block 11. A fixing block 12 is fixedly connected to the bottom of the other door and window frame 2.

[0023] First, the mounting frame 1 is fixed to the preset installation position of the door and window. Then, the glass 3 is embedded inside the door and window frame 2. A rubber frame 4 is installed at the gap between the glass 3 and the door and window frame 2 to form an initial seal and prevent rainwater from seeping through the gap. Next, the door and window frame 2 is assembled into the mounting frame 1. In rainy weather, the outer inclined strip 7 directly diverts most of the rainwater to the outside. When rainwater enters the door and window frame 2, the baffle 5 at the bottom of the mounting frame 1 blocks it between the baffle 5 and the mounting frame 1. Under the guidance of the inclined plate 601, the rainwater preferentially enters the sealing groove 13. The accumulated water pressure squeezes the drainage mechanism 6, causing it to open the inlet of the water guide groove 8. The rainwater flows along the inclined plate 601. The water channel 8 is set at an angle to discharge water. At this time, the rainwater impacts the rotating plate 10 and leads the rainwater to the outside of the door and window frame 2. The angled setting of the water channel 8 effectively avoids backflow and prevents it from seeping into the room and damaging the decoration. Finally, when the window is closed and locked, the rotating drive wheel 15 drives the plug-in mechanism 9 to rotate. Since the spiral groove 14 and the slide rod 902 fixed in the mounting block 11 form a sliding fit, the slide rod 902 drives the plug-in mechanism 9 to move and insert into the fixed block 12, completing the mechanical locking of the door and window. This optimizes the traditional lock that requires multiple rotations to achieve the docking of the lock handle and the lock, thereby achieving a one-time stable locking and improving the convenience of use and structural reliability.

[0024] like Figure 1-2 As shown, the drainage mechanism 6 includes an inclined plate 601, a guide block 602, a sealing plate 603, and a rubber spring 604. The inclined plate 601 has multiple sealing grooves 13 inside. One end of the guide block 602 is fixedly connected to one side of the sealing plate 603, and the other end of the guide block 602 is slidably connected to the inside of the inclined plate 601. Both ends of the sealing plate 603 are slidably connected to the inside of the sealing grooves 13, and the bottom end of the sealing plate 603 is fixedly connected to one end of the rubber spring 604. The bottom end of the inclined plate 601 is fixedly connected to the bottom of the mounting frame 1. The sealing grooves 13 are connected to the water guide channel 8. The bottom end of the rubber spring 604 is fixedly connected to the bottom of the mounting frame 1.

[0025] The outer inclined strip 7 directly diverts most of the rainwater to the outside. When rainwater enters the door and window frame 2, the baffle 5 at the bottom of the mounting frame 1 blocks it between the baffle 5 and the mounting frame 1. Under the guidance of the inclined plate 601, the rainwater preferentially enters the sealing groove 13. The accumulated water pressure squeezes the sealing plate 603, causing it to move down along the trajectory of the guide block 602 and compress the rubber spring 604, thereby opening the water inlet of the water guide 8. The rainwater is discharged along the inclined water guide 8. At this time, the rainwater impacts the rotating plate 10 and leads the rainwater to the outside of the door and window frame 2. The inclined setting of the water guide 8 effectively avoids backflow and prevents it from seeping into the room and damaging the decoration.

[0026] like Figure 1 , Figure 3 and Figure 4As shown, the insertion mechanism 9 includes a cam 901, a slide rod 902, and an insertion rod 903. The outer wall of the cam 901 has a spiral groove 14, and the interior of the cam 901 is fixedly connected to the outer wall of the insertion rod 903. One end of the slide rod 902 is slidably connected to the interior of the spiral groove 14. The cam 901 is located inside the mounting block 11. The end of the slide rod 902 away from the spiral groove 14 is fixedly connected to the interior of the mounting block 11. One end of the insertion rod 903 is fixedly connected to a drive wheel 15, and the other end of the insertion rod 903 is inserted into the interior of the fixing block 12. The outer wall of the insertion rod 903 is movably connected to the interior of the mounting block 11.

[0027] When the window is closed and locked, the drive wheel 15 rotates to drive the insert rod 903 and the cam 901 to rotate synchronously. Since the spiral groove 14 and the slide rod 902 fixed in the mounting block 11 form a sliding fit, the cam 901 moves along the trajectory of the slide rod 902 when it rotates, driving the insert rod 903 to move axially and insert into the fixed block 12, thus completing the mechanical locking of the door and window. This optimizes the traditional lock that requires multiple rotations to achieve the docking of the lock handle and the lock, thereby achieving a one-time stable locking and improving the convenience of use and structural reliability.

[0028] Working principle: First, the mounting frame 1 is fixed to the preset installation position of the door and window. Then, the glass 3 is embedded inside the door and window frame 2. A rubber frame 4 is installed at the gap between the glass 3 and the door and window frame 2 to form an initial seal and prevent rainwater from seeping through the gap. Next, the door and window frame 2 is assembled into the mounting frame 1. In rainy weather, the outer inclined strip 7 directly diverts most of the rainwater to the outside. When rainwater enters the door and window frame 2, the baffle 5 at the bottom of the mounting frame 1 blocks it between the baffle 5 and the mounting frame 1. Under the guidance of the inclined plate 601, the rainwater preferentially enters the sealing groove 13, and the accumulated water pressure squeezes the sealing plate 6. 03, causing it to move down along the trajectory of guide block 602 and compress rubber spring 604, thereby opening the water inlet of water guide channel 8. Rainwater is discharged along the inclined water guide channel 8. At this time, the rainwater impacts rotating plate 10 and leads the rainwater to the outside of door and window frame 2. Finally, when the window is closed and locked, rotating drive wheel 15 drives insert rod 903 and cam 901 to rotate synchronously. Since spiral groove 14 and slide rod 902 fixed in mounting block 11 form a sliding fit, when cam 901 rotates, it moves along the trajectory of slide rod 902, driving insert rod 903 to move axially and insert into fixed block 12, completing the mechanical locking of door and window.
