Description

Technical Field

[0001] This utility model relates to the field of drift window technology, and in particular to an inward drift ventilation system. Background Technology

[0002] In the field of building door and window technology, traditional sliding windows and casement windows are unable to meet the comprehensive needs of modern buildings for sealing, energy saving and ease of operation due to their respective performance limitations. Against this background, drift windows have emerged.

[0003] Drift windows integrate advanced mechanical transmission principles with a precise sealing structure design. Their unique opening mechanism eliminates the drawbacks of traditional sliding windows, such as dust accumulation and poor sealing, while also overcoming the problems of casement windows occupying indoor and outdoor space and being susceptible to wind pressure. Through the synergistic effect of an innovative multi-point locking system and high-strength hardware, drift windows achieve smooth lateral sliding opening of the window sash while maintaining excellent airtightness, watertightness, and wind pressure resistance. They effectively block heat transfer and noise interference, providing modern buildings with a door and window solution that combines aesthetics and high performance.

[0004] Patent document CN221277509U discloses a drifting component for a drifting window, comprising: an upper guide rod and a lower guide rod respectively disposed on a sliding track; the upper guide rod is hinged to a first rotating plate on its side; the first rotating plate is hinged to a first support plate via a bearing sleeve; the middle part of the first support plate is hinged to a second support plate; one end of the first support plate is hinged to a limiting plate via an mounting column; one end of the limiting plate is hinged to the second support plate; and the limiting plate has guide limiting holes on its surface. The limiting plate is fixedly disposed on the top surface of the window; the lower guide rod is hinged to the second rotating plate on its side; the second rotating plate is hinged to a mounting column; and the mounting column is hinged to the bottom of the window. In rainy weather, pulling the upper part of the window alone will cause the first support plate to move a certain distance relative to the limiting plate, thereby ensuring that the upper part of the window has a certain opening, preventing rain from getting in while ensuring ventilation. The window's structural configuration is diversified.

[0005] As in the prior art of the aforementioned patent, the drift window is generally composed of two parts: a fixed window and a sliding window. The track of the sliding window is located at the top and bottom of the fixed window frame and is exposed to the outside. The track is not protected, and with the accumulation of dust over time, the surface dust will hinder the normal use of the track, making the slider slide less smoothly on the track and causing resistance. Furthermore, the track being exposed to the air will accelerate its natural corrosion and reduce its service life. Utility Model Content

[0006] The purpose of this invention is to provide an inward-drifting ventilation system to address the aforementioned shortcomings of the prior art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: an inward-drifting ventilation system, comprising a main window frame, a fixed window frame, a drifting window frame, and a handle disposed on the drifting window frame. The fixed window frame is fixedly installed inside the main window frame, and a fixed window body is fixedly installed on the fixed window frame. Slide rails are fixedly installed on the top and bottom walls inside the main window frame. Sliding blocks are slidably installed inside both slide rails. Hinges are provided on multiple sliding blocks. Multiple grooves are provided on the drifting window frame. One end of each hinge is rotatably connected to a sliding block, and the other end of each hinge is rotatably connected to a groove. A first sliding groove and a second sliding groove are provided inside the drifting window frame. The first sliding groove is slidably adapted to the hinge, and the second sliding groove is adapted to the sliding block. One end of the first sliding groove is connected to the second sliding groove, and the other end of the first sliding groove is connected to the outside. A sealing component is provided at the end of the first sliding groove closest to the outside. Lubricant filling components are provided at the top and bottom of the drifting window frame.

[0008] As a further description of the above technical solution: the sealing component includes a sealing strip and a groove, the groove is formed at the top of the first slide groove, the sealing strip is adapted to the first slide groove, and a wedge-shaped surface is provided at the end of the sealing strip near the drift window.

[0009] As a further description of the above technical solution: a first spring is fixedly installed inside the groove, and the first spring is fixedly connected to the top end of the sealing strip.

[0010] As a further description of the above technical solution: the lubricant filling assembly includes an injection cavity opened inside the drift window frame, and a removable sealing strip is provided at one end of the injection cavity.

[0011] As a further description of the above technical solution: the lubricant filling assembly includes a second spring disposed inside the filling cavity. A connecting seat is fixedly installed at the bottom end of the second spring, and a ball is rotatably connected to the bottom end of the connecting seat. The ball penetrates the top wall of the second groove, the upper half of the ball is disposed inside the filling cavity, and the lower half of the ball is disposed inside the second groove.

[0012] As a further description of the above technical solution: the inside of the infusion cavity is provided with an inclined surface, and the inclined surface is inclined downward from the sealing strip towards the ball.

[0013] This invention provides an inward-drifting ventilation system. It offers the following advantages: pulling the drifting window frame outward causes the hinge shaft to slide outward, pulling the drifting window frame moves the slider and hinge shaft towards the fixed window position. During this sliding process, the slider and hinge shaft slide against the second and first sliding grooves respectively. The first sliding groove ensures the hinge shaft is not obstructed by the fixed window frame. The use of a concealed track allows the slider and hinge shaft to slide inside the fixed window frame. When the drifting window frame is closed, the sealing component seals the first sliding groove, preventing dust from entering the fixed window frame through it. The internal track can be lubricated using a lubricant filling component, eliminating the need for disassembly and maintenance.

[0014] It should be understood that the foregoing general description and the following detailed description are exemplary and illustrative only, and are not intended to limit this disclosure.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Reference Figure 1-8A type of inward-drifting ventilation system includes a main window frame 1, a fixed window frame 2, a drifting window frame 8, and a handle 10 mounted on the drifting window frame 8. The fixed window frame 2 is fixedly installed inside the main window frame 1, and a fixed window body 3 is fixedly installed on the fixed window frame 2. Slide rails 4 are fixedly installed on the top and bottom walls inside the main window frame 1. Sliding sliders 5 are slidably installed inside each of the two slide rails 4. Hinges 6 are provided on each of the sliding sliders 5. Multiple slots 7 are formed on the drifting window frame 8, and one end of each of the hinges 6 connects to a sliding slider. 5. A rotatable connection is made, with the other end of each of the multiple hinge shafts 6 rotatably connected to the groove 7. The drifting window frame 8 has a first sliding groove 11 and a second sliding groove 12 inside. The first sliding groove 11 is slidably adapted to the hinge shaft 6, and the second sliding groove 12 is adapted to the slider 5. One end of the first sliding groove 11 is connected to the second sliding groove 12, and the other end of the first sliding groove 11 is connected to the outside. A sealing component is provided at the end of the first sliding groove 11 near the outside. Lubricant filling components are provided at both the top and bottom of the drifting window frame 8. A locking assembly is provided between the aforementioned drift window frame 8 and the main window frame 1, which is locked and unlocked by the handle 10. This technology is existing technology and will not be described in detail. When the drift window is closed, the hinge shaft 6 is located inside the groove 7, and the drift window is located between two slide rails 4 and closes the slide rails 4. When it is necessary to open the drift window, the drift window frame 8 is unlocked by the handle 10, and the drift window frame 8 is pulled outward. The hinge shaft 6 causes the drift window frame 8 to slide outward. Pulling the drift window frame 8 causes the slider 5 and the hinge shaft 6 to slide towards the position of the fixed window 3. During the sliding process, the slider 5 and the hinge shaft 6 slide relative to the second slide groove 12 and the first slide groove 11, respectively. The opening of the first slide groove 11 ensures that the hinge shaft 6 is not blocked by the fixed window frame 2. The use of a hidden track allows the slider 5 and the hinge shaft 6 to slide inside the fixed window frame 2. When the drift window frame 8 is closed, the sealing component can seal the first slide groove 11 to prevent dust from entering the interior of the fixed window frame 2 through the first slide groove 11. Subsequently, the internal track can be lubricated by the lubricant filling component, without the need for disassembly and maintenance.

[0028] As a preferred technical solution of this embodiment, the sealing component includes a sealing strip 15 and a groove 13. The groove 13 is formed at the top of the first slide groove 11. The sealing strip 15 is adapted to the first slide groove 11. A wedge-shaped surface 16 is provided at one end of the sealing strip 15 near the drift window 9. When the drift window slides laterally, the hinge shaft 6 contacts the wedge-shaped surface 16 of the sealing strip 15, which can press the wedge-shaped surface 16 upward and press the wedge-shaped surface 16 into the interior of the groove 13, thereby facilitating the sliding of the hinge shaft 6 inside the first slide groove 11.

[0029] As a preferred technical solution of this embodiment, a first spring 14 is fixedly installed inside the groove 13, and the first spring 14 is fixedly connected to the top end of the sealing strip 15; when the hinge shaft 6 leaves the first slide groove 11, the sealing strip 15 can be reset under the action of the first spring 14, thereby achieving the sealing of the first slide groove 11 by the sealing strip 15 when the drift window 9 is closed.

[0030] As a preferred technical solution of this embodiment, the lubricant filling assembly includes an injection cavity 18 opened inside the drift window frame 8, and a detachable sealing strip 17 is provided at one end of the injection cavity 18; the sealing strip 17 can be installed and removed in a detachable manner, so that the corresponding lubricant can be injected into the inside of the injection cavity 18.

[0031] As a preferred embodiment, the lubricant filling assembly further includes a second spring 20 disposed inside the filling cavity 18. A connecting seat 21 is fixedly installed at the bottom end of the second spring 20, and a ball bearing 22 is rotatably connected to the bottom end of the connecting seat 21. The ball bearing 22 penetrates the top wall of the second slide groove 12. The upper half of the ball bearing 22 is disposed inside the filling cavity 18, and the lower half of the ball bearing 22 is disposed inside the second slide groove 12. When the slider 5 slides inside the second slide groove 12, the lubricant injected into the filling cavity 18 presses the ball bearing 22 upward. As the ball bearing 22 rolls, the lubricant is injected downward between the second slide groove 12 and the slider 5 to lubricate the slider 5. The second spring 20 can push the ball bearing 22 downward to seal the lubricant.

[0032] As a preferred technical solution of this embodiment, the inside of the injection cavity 18 is provided with an inclined surface 19, and the inclined surface 19 is inclined downward from the sealing strip 17 toward the ball 22; the inclined surface 19 can facilitate the lubricant to slide downward and enter the cavity around the ball 22.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
