Description

Technical Field

[0001] This utility model relates to the field of system doors and windows technology, specifically a waterproof and sealed system door and window. Background Technology

[0002] System windows and doors are high-performance building window and door solutions that employ integrated design and precision manufacturing processes. Their core feature is the superior waterproofing, sealing, thermal insulation, sound insulation, and durability achieved through the collaborative work of multiple component systems. Compared to traditional windows and doors, system windows and doors utilize a modular design, comprising multiple subsystems such as profiles, sealing systems, hardware, and glass. Each component undergoes rigorous matching and testing to ensure optimal overall performance.

[0003] In the prior art, a novel waterproof door and window with strong sealing performance is disclosed in patent publication number "CN217233257U". This includes a frame and a glass window. The glass window is located inside the frame, and hydrophobic structures are provided at both ends of the glass window. Sealing structures are provided on both sides of the inner part of the frame, and auxiliary structures are provided at both ends of the inner part of the frame. The sealing structure includes a first sealing strip, a second sealing strip, an iron sheet, and a magnetic block. The second sealing strip is fixed to both sides of the inner part of the frame, and a magnetic block is provided inside the second sealing strip. This invention, by providing a sealing structure, ensures that when the glass window is closed, the first sealing strip on one side abuts against the second sealing strip. The use of the first and second sealing strips improves the sealing effect when the frame and the glass window are in contact. By improving the sealing effect, it prevents, to a certain extent, the problem of reduced heat insulation, sound insulation, and other functions due to poor sealing performance in this type of door and window.

[0004] However, existing technologies still have significant shortcomings. Traditional system doors and windows mainly rely on the compression of rubber sealing strips to achieve waterproofing. However, with repeated opening and closing and friction, the sealing gaskets will inevitably wear and age, resulting in a decline in sealing performance. In rainy weather, rainwater is prone to seepage, thus causing the doors and windows to lose their waterproofing effect. Utility Model Content

[0005] The purpose of this utility model is to provide a waterproof and sealed system door and window to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a waterproof and sealed system door and window, including a frame, a guide rail at the opening on the front of the frame, a sliding window inside the guide rail, a protective cover on the back of the frame, a winding drum rotatably connected inside the protective cover, a waterproof cloth wrapped around the surface of the winding drum, a counterweight head connected to one end of the waterproof cloth, a guide plate fixed to the surface of the protective cover, a scraping end at one end of the guide plate with a pointed tip that contacts one side of the waterproof cloth, and clamps on both sides of the back of the frame, with the portions near the sides of the waterproof cloth located between the clamps and the back of the frame.

[0007] As can be seen, the above technical solution, which adopts an automatic roll-up method for the waterproof fabric, greatly improves the waterproof performance of the sliding window. In rainy weather, the waterproof fabric automatically descends through sensors or manual triggering, completely covering the outdoor side of the sliding window and the frame rail area. The waterproof fabric is tightly fixed on both sides by elastic clamps, forming a sealed waterproof barrier on the back of the window frame. This effectively solves the problem of water seepage caused by the wear of the sealing gaskets in traditional sliding windows due to long-term use. When rainwater seeps in from the wear gap between the sliding window and the frame, it will be completely blocked by the waterproof fabric, preventing water from directly contacting the window body and the internal structure of the rail.

[0008] Preferably, the two guide rails are distributed one in front of the other, and the two sliding window positions are slidably connected to the corresponding guide rails.

[0009] As can be seen, in the above technical solution, rubber strips can be added to the surface of the sliding window and the corresponding positions of the guide rail or frame to play a role in sealing and waterproofing, while allowing the sliding window to move linearly to complete the opening or closing of the window.

[0010] Preferably, the waterproof cloth passes through the opening on the bottom surface of the protective cover, and the counterweight head is perpendicular to the bottom surface of the frame.

[0011] As can be seen, in the above technical solution, when the winding drum is winding or unwinding the waterproof cloth, the waterproof cloth can pass through the opening at the bottom of the winding drum and be wound or lowered by the weight of the counterweight head.

[0012] Preferably, the back of the frame is screwed to a support plate, and the counterweight head is vertically aligned with the mating cavity on the top surface of the support plate.

[0013] As can be seen, in the above technical solution, the counterweight head can eventually descend into the mating cavity opened on the top surface of the support plate, thereby protecting the counterweight head.

[0014] Preferably, a spring is installed in the mounting opening on the back of the frame, and one end of the spring is fixed to the clamp.

[0015] As can be seen, in the above technical solution, the spring can be used to clamp or push the clamping plate, so that the clamping plate can clamp the waterproof cloth when needed and can be moved when not needed, making it convenient to roll up the waterproof cloth.

[0016] Preferably, a motor is installed inside the protective cover, and gears are installed at the rotating end of the motor and one end of the winding drum, and the two gears mesh with each other.

[0017] As can be seen, in the above technical solution, the mechanical transmission of gears can enable the winding drum to rotate forward or reverse under the drive of the motor.

[0018] Preferably, the front of the frame has a threaded hole, and a threaded rod is threaded into the threaded hole. One end of the threaded rod is fixed with a pusher, and the position of the pusher corresponds to that of the clamping plate.

[0019] As can be seen, in the above technical solution, one end of the threaded rod is protected by a protective groove, which makes it convenient for the user to manually rotate the threaded rod to move it and push the clamping plate.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] The automatic roll-up of the waterproof fabric significantly improves the waterproof performance of sliding windows. During rainy weather, the waterproof fabric automatically descends via sensors or manual triggering, completely covering the outdoor side of the sliding window and the frame rail area. The waterproof fabric is tightly secured on both sides by elastic clamps, forming a sealed waterproof barrier on the back of the window frame. This effectively solves the water seepage problem caused by wear and tear on the sealing gaskets of traditional sliding windows over long-term use. When rainwater seeps in through the wear gaps between the sliding window and the frame, it is completely blocked by the waterproof fabric, preventing direct contact between water and the window frame and the internal structure of the rails. It directly utilizes the principle of physical isolation to fundamentally block the path of rainwater penetration, thereby improving the waterproof effect of doors and windows. The structure is simple, and the roll-up mechanism is installed inside a protective cover, with a deflector plate to prevent rainwater from entering the protective cover. The clamps use the spring's rebound force to clamp and limit the waterproof fabric on both sides, while the spring's elasticity allows the clamps to be manually pushed, facilitating the roll-up operation of the waterproof fabric.

[0030] 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.

[0031] Please see Figures 1-7 This utility model provides a technical solution:

[0032] Example 1: A waterproof and sealed system door and window: Includes a frame 1, with guide rails 2 at the opening on the front of the frame 1. Sliding windows 3 are installed inside the guide rails 2. The two guide rails 2 are arranged front and back, and the two sliding windows 3 are slidably connected to their corresponding guide rails 2. The sliding windows 3 can move linearly between the guide rails 2 inside the frame 1 to open or close the window. Rubber sealing strips are installed at waterproof locations on the surface of the sliding windows 3, ensuring a tight seal with the frame 1, guide rails 2, and adjacent sliding windows 3, giving the sliding windows 3 excellent waterproof and sealing performance and preventing rainwater from directly entering from the outside. The sliding window 3 is installed indoors. A protective cover 4 is located on the back of the frame 1. A winding drum 9 is rotatably connected inside the protective cover 4. A waterproof cloth 7 is wrapped around the surface of the winding drum 9. One end of the waterproof cloth 7 is connected to a counterweight 8. The waterproof cloth 7 passes through an opening at the bottom of the protective cover 4, and the counterweight 8 is perpendicular to the bottom surface of the frame 1. Clamping plates 11 are located on both sides of the back of the frame 1, with the portion near the sides of the waterproof cloth 7 positioned between the clamping plates 11 and the back of the frame 1. Because the sliding window 3 is prone to wear and tear on the sealing strip after long-term use, resulting in a loss of waterproofing effect, a waterproof cloth 7 is added to the back of the frame 1. The waterproof cloth 7 is wrapped around the winding drum 9. On the surface of the roll 9, the counterweight head 8 at the end is perpendicular to the bottom surface of the frame 1. The roll 9 is driven by mechanical transmission to roll up the waterproof cloth 7. It can be equipped with a rain sensor to alert the user when it rains. When needed, the clamping plate 11 can be pushed outward so that the waterproof cloth 7 and the counterweight head 8 can pass through the gap between the clamping plate 11 and the back of the frame 1. Finally, the counterweight head 8 falls into the mating cavity inside the support plate 10. At this time, the clamping plate 11 is restored. The clamping plate 11 is clamped on both sides of the waterproof cloth 7 by the rebound force of the spring 12, so as to limit the waterproof cloth 7 and prevent it from being affected by the environment. To prevent the waterproof fabric 7 from swaying significantly on the outside, the waterproof fabric 7 completely covers the outdoor sliding window 3 and the guide rail 2 area of ​​the frame 1, forming a sealed waterproof barrier on the back of the window frame. This effectively solves the water leakage problem caused by the wear of the sealing gasket of the traditional sliding window 3 due to long-term use. The support plate 10 is fixed to the back of the frame 1 with screws, and the counterweight head 8 is vertically aligned with the mating cavity on the top surface of the support plate 10. The counterweight head 8 is mainly used to add gravity to the end of the waterproof fabric 7 when it falls, making its fall more stable, until the counterweight head 8 falls into the mating cavity of the support plate 10.

[0033] A spring 12 is installed in the mounting opening on the back of frame 1, and one end of the spring 12 is fixed to the clamp 11. The clamp 11 is directly connected to the spring 12 in the groove on the back of frame 1. The spring 12 is embedded, and the included angle of the inner side of the clamp 11 is L-shaped. Under normal circumstances, the clamp 11 is pulled by the spring 12, making it fit tightly against the back of frame 1 and hiding the spring 12. A threaded hole 13 is passed through the front of frame 1. A threaded rod 14 is threaded into the threaded hole 13. A push head 15 is fixed to one end of the threaded rod 14, and the push head 15 is connected to the clamp. The positions of the plates 11 correspond to each other. When the waterproof cloth 7 is needed, the threaded rod 14 can be rotated indoors, so that the threaded rod 14 rotates and moves in the threaded holes 13 on both sides of the frame 1 until the push head 15 pushes the clamping plate 11 outward, so that the waterproof cloth 7 can pass through the clamping plate 11 to the gap on the back of the frame 1 and fall directly down. This gap can also act as a slide rail to limit the counterweight and the waterproof cloth 7 to ensure that it can fall normally. After the fall is completed, the threaded rod 14 is rotated in the opposite direction. At this time, the clamping plate 11 is clamped on both sides of the waterproof cloth 7 by the rebound force of the spring 12.

[0034] Example 2:

[0035] Based on Embodiment 1, a guide plate 5 is fixed to the surface of the protective cover 4. One end of the guide plate 5 is provided with a scraping end 6, which is a pointed tip and contacts one side of the waterproof cloth 7. A motor 17 is installed inside the protective cover 4. It should be noted that the protective cover 4 is located on the back of the frame 1 and is partially embedded, so as not to affect the overall aesthetics. At the same time, the protective cover 4 can protect the internal components such as the motor 17, preventing rainwater from directly contacting them and causing damage to the components. The waterproof cloth 7 passes through the opening at the bottom of the protective cover 4 and moves downward or rolls up. The guide plate 5 added to the surface of the protective cover 4 can protect the bottom opening and prevent rainwater from directly entering through the opening. When rainwater falls into the protective cover 4, it can slide down the guide plate 5 on its own. One end of the guide plate 5 is a scraping end 6, which is pointed. The pointed part directly contacts one side of the waterproof cloth 7. When the waterproof cloth 7 is rolled up, the water on its surface can be scraped off, so as to avoid a large amount of water remaining after rolling up and affecting the internal components of the protective cover 4. Gears 16 are installed at the rotating end of the motor 17 and one end of the winding drum 9, and the two gears 16 mesh with each other. It should be noted that the gears 16 inside the protective cover 4 are located on the surface of the winding drum and the rotating end of the motor 17. The two gears 16 mesh with each other. When the motor 17 is working, it can control the winding drum 9 to rotate forward or backward to complete the winding of the waterproof cloth 7.

[0036] Working Principle: The sliding window 3 moves linearly between the guide rails 2 inside the frame 1 to open or close the window. Rubber sealing strips are installed at waterproof locations on the surface of the sliding window 3, ensuring a tight seal between the window and the frame 1, guide rails 2, and adjacent sliding windows 3. This provides excellent waterproof sealing, preventing rainwater from directly entering the room. However, since the sealing strips are prone to wear and tear over time, reducing their waterproof effect, a waterproof cloth 7 is added to the back of the frame 1. The waterproof cloth 7 is wrapped around the surface of the winding drum 9, with the counterweight 8 at the end perpendicular to the bottom of the frame 1. Mechanical transmission drives the winding drum 9 to rewind the waterproof cloth 7. A rain sensor can be added to alert the user during rain and allow for further adjustments when needed. Push the clamp 11 outward so that the waterproof cloth 7, along with the counterweight 8 at the end, can pass through the gap between the clamp 11 and the back of the frame 1. Finally, the counterweight 8 falls into the mating cavity inside the support plate 10. At this time, the clamp 11 is restored. The clamp 11 is clamped on both sides of the waterproof cloth 7 by the rebound force of the spring 12, thereby limiting the position of the waterproof cloth 7 and preventing the waterproof cloth 7 from shaking significantly on the outside due to environmental influences. The waterproof cloth 7 completely covers the outdoor sliding window 3 and the guide rail 2 area of ​​the frame 1, forming a sealed waterproof barrier on the back of the window frame. This effectively solves the water leakage problem caused by the wear of the sealing gasket of the traditional sliding window 3 due to long-term use. Similarly, when the waterproof cloth 7 is rolled up, push the clamp 11, and the winding drum 9 will roll up and wrap the waterproof cloth 7 until it is in the specified position.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
