Description
Technical Field
[0001] This utility model relates to the field of door and window technology, and in particular to a sealing and drainage structure for a sliding window and the sliding window itself. Background Technology
[0002] Sliding windows are a common type of door and window. They open and close by sliding the window sash horizontally along a track. They offer advantages such as space saving, ease of operation, and high adaptability, making them widely used in residential, commercial, and public buildings. However, existing sliding windows have some issues with their sealing and drainage structures, affecting their performance and user experience.
[0003] Traditional sliding window bottom track structures typically use a one-piece design, which has the following disadvantages:
[0004] High processing difficulty: The drainage holes of the integral lower rail structure are complex to process, requiring direct drilling on the profile. This not only increases the processing difficulty but also reduces production efficiency, leading to increased production costs.
[0005] Inconvenient maintenance: Once the drainage system becomes blocked or malfunctions, the disassembly and repair of the integrated lower rail structure is very difficult, requiring a lot of time and manpower, which seriously affects the product's service life and user experience.
[0006] Insufficient sealing performance: Existing sliding windows usually do not have anti-backflow devices for their drainage holes, which can cause backflow of air in the lower track due to wind pressure during windy weather, resulting in a whistling sound. At the same time, rainwater may also backflow into the room through the drainage holes, affecting airtightness and watertightness. Utility Model Content
[0007] The purpose of this utility model is to provide a sealing and drainage structure for a sliding window and a sliding window in general. By adopting a split lower track design and an anti-backflow drainage component, the sealing performance, drainage efficiency and maintenance convenience of the sliding window are effectively improved.
[0008] In a first aspect, this utility model provides a sealing and drainage structure for a sliding window, comprising:
[0009] Bottom rail profile;
[0010] A thermal insulation strip is provided on the lower rail profile, and the thermal insulation strip has mounting holes that pass through both opposite ends;
[0011] The outer track profile and the inner track profile are detachably mounted on the lower track profile, and the outer track profile and the inner track profile are respectively located on opposite sides of the heat insulation strip. The inner track profile is provided with a first drainage hole, and the outer track profile is provided with a second drainage hole.
[0012] A drainage component is disposed within the mounting hole. The drainage component enables water and / or airflow to flow from the first drainage hole to the second drainage hole, and the drainage component also prevents water and / or airflow from flowing from the second drainage hole to the first drainage hole.
[0013] The sliding window sealing and drainage structure provided by this utility model adopts a detachable design for the outer and inner track profiles, significantly simplifying the processing technology of the drainage holes and making the processing of the first and second drainage holes more convenient and precise. This split structure not only facilitates installation but also facilitates later maintenance and repair. The drainage components are cleverly hidden in the mounting holes of the thermal insulation strip, which can guide the unidirectional flow of water and air while effectively preventing backflow of external water and air, significantly improving the airtightness and watertightness of the sliding window. Especially in inclement weather, it can effectively prevent rainwater leakage and wind noise, ensuring indoor comfort.
[0014] Furthermore, the drainage assembly includes a connecting cover plate and a rotating cover plate. The connecting cover plate is disposed in the mounting hole and is also provided with a third drainage hole. The rotating cover plate is rotatably disposed at the third drainage hole, and the connecting cover plate is also provided with a limiting block facing the third drainage hole. When water flow and / or air flow from the second drainage hole to the rotating cover plate, the limiting block can restrict the rotating cover plate from rotating toward the inner track profile to close the third drainage hole.
[0015] By employing the above technical solution, the drainage assembly, through the cooperation of the connecting cover and the rotating cover, can precisely guide water and air flow from the first drainage hole to the second drainage hole, ensuring a reasonable drainage path and improving drainage efficiency. Furthermore, through the cooperation of the rotating cover and the limiting block, the drainage assembly not only achieves unidirectional drainage but also has an automatic closing function, reducing potential problems caused by open drainage holes, such as insects entering and dust accumulation.
[0016] Furthermore, mounting buckles are provided on opposite sides of the connecting cover plate, and mounting slots are provided on opposite sides of the mounting hole wall. The mounting buckles can be inserted into the mounting slots to fix the connecting cover plate in the mounting hole.
[0017] The above-mentioned technical solution, with its matching design of the mounting buckle and mounting slot, makes the installation and disassembly of the drainage component simpler and faster. During installation, simply align the mounting buckle with the mounting slot and insert it to secure it; during disassembly, simply pry or press the mounting buckle gently to remove it from the mounting slot, helping to reduce the difficulty of installation and maintenance.
[0018] Furthermore, the mounting hole has a first arc surface on the hole walls on both sides, and the mounting buckle has a second arc surface, wherein the first arc surface and the second arc surface can fit together.
[0019] By adopting the above technical solution, the design of the first and second arc surfaces plays a guiding role, which makes the installation buckle insert into the installation slot more smoothly, reduces the requirement for precise alignment during installation, and further reduces the installation difficulty.
[0020] Furthermore, the lower rail profile is provided with a first snap-fit groove and a second snap-fit groove, the outer rail profile is provided with a first snap-fit, and the inner rail profile is provided with a second snap-fit. The first snap-fit can be inserted into the first snap-fit groove for locking and fixing, and the second snap-fit can be inserted into the second snap-fit groove for locking and fixing.
[0021] By employing the above technical solution, and by setting a first and a second snap-fit groove on the lower rail profile, and setting a first and a second snap-fit on the outer and inner rail profiles respectively, this snap-fit fixing method allows for quick installation and disassembly of the outer and inner rail profiles. This design greatly simplifies the installation process, reduces installation difficulty, and also facilitates later maintenance and repair, improving the maintainability of the product.
[0022] Furthermore, two first buckle slots and two second buckle slots are respectively spaced apart on the lower rail profile. There are two first buckles and two second buckles. The two first buckles can be inserted into the corresponding first buckle slots, and the two second buckles can be inserted into the corresponding second buckle slots.
[0023] By adopting the above technical solution, by setting two first snap-fit grooves and two second snap-fit grooves on the lower rail profile, and setting two first snaps and two second snaps on the outer rail profile and the inner rail profile respectively, this double snap-fit design can better disperse external forces and reduce loosening or displacement caused by local stress concentration.
[0024] Furthermore, the lower rail profile is also provided with a fourth drainage hole, which is located on the side of the outer rail profile away from the inner rail profile. The fourth drainage hole can output the water flow and / or air flow output from the second drainage hole to the outside of the lower rail profile.
[0025] By adopting the above technical solution, a three-stage drainage path is formed by setting a fourth drainage hole on the lower rail profile, from the first drainage hole to the second drainage hole and then to the fourth drainage hole. This ensures that water can be smoothly discharged from the inside to the outside, reducing the possibility of water accumulation and improving drainage efficiency.
[0026] Furthermore, the inner track profile is also provided with a first drainage cavity, and the number of the first drainage holes is two, with the two first drainage holes respectively located on opposite sides of the first drainage cavity.
[0027] Furthermore, the outer track profile is also provided with a second drainage cavity, and the number of the second drainage holes is two, with the two second drainage holes respectively located on opposite sides of the second drainage cavity.
[0028] Secondly, the present invention provides a sliding window, including the sealing and drainage structure of any of the above-mentioned sliding windows.
[0029] As can be seen from the above, the sealing and drainage structure of the sliding window provided by this utility model adopts a detachable design of the outer track profile and the inner track profile, which significantly simplifies the processing technology of the drainage holes, making the processing of the first and second drainage holes more convenient and precise. This split structure is not only easy to install, but also easy to maintain and repair later. The drainage components are cleverly hidden in the mounting holes of the thermal insulation strip, which can guide the unidirectional flow of water and air, and effectively block the backflow of external water and air, significantly improving the airtightness and watertightness of the sliding window. Especially in inclement weather, it can effectively prevent rainwater leakage and wind noise, ensuring indoor comfort.
