Description

Technical Field

[0001] This utility model relates to the field of soundproof window technology, specifically to a novel noise-reducing window. Background Technology

[0002] In architecture, a window is an opening in a wall or roof to allow light or air to enter a room. It is an essential structural element of any building, serving multiple functions including ventilation, lighting, and sound insulation. Currently, most windows are made of ordinary or tempered glass, which offers relatively poor sound insulation. Some windows use vacuum glass, which can improve sound insulation; however, large gaps at the connection between the window frame and the wall can reduce this effect.

[0003] Patent document CN222595933U discloses a sound-insulating and noise-reducing aluminum alloy window. When installed into the aluminum alloy frame, the top of the aluminum alloy window body pushes against the slide rail and the support plate on it upward through the extension and contraction of the spring. After installation, the slide rail and the support plate themselves drive the spring to stretch, so that the slide rail and the track fit tightly together, improving the sealing performance of the aluminum alloy window. In addition, a second sound-insulating cotton strip is set at the joint between the support plate and the aluminum alloy frame. The spring force squeezes downward, so that the second sound-insulating cotton strip blocks the gap between the support plate and the aluminum alloy frame, enhancing the sound insulation performance of the aluminum alloy window. Sound-absorbing cotton is also filled in the cavity of the slide rail, which can absorb noise and reduce the impact of noise on the residents. A retractable first sound-insulating strip is installed inside the inner window frame at the junction of the two aluminum alloy window panels. This strip is controlled by a push-pull switch, which connects to a fixed plate. Pushing the plate extends the entire first sound-insulating strip, sealing the gap between the two window panels. When the window is open or the first sound-insulating strip is not needed, it can be retracted into the aluminum alloy window frame using the push-pull switch, enhancing the airtightness of the two window panels. However, in this design, the sliding rail is connected to the window frame. After repeated pushing and pulling of the window, the gap between the rail and the window increases, affecting the sound insulation effect. Furthermore, after the two windows are closed, sealing the gap requires manual operation of a handle, which is cumbersome. Utility Model Content

[0004] The main purpose of this utility model is to provide a new type of noise-reducing window with good sound insulation and the ability to automatically seal the gap between the two window frames after they are closed.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0006] A novel noise-reducing window includes a rectangular frame with two tracks fixed to opposite ends on the top and bottom sides. The two upper tracks and two lower tracks are arranged front to back. Two staggered window panels are installed inside the frame and are slidably connected to the tracks on the top and bottom sides. Each track includes a pad fixedly connected to the frame. A protruding strip is fixed to one end of the pad facing the window panel and is located in a long groove of the window panel, making slidable contact with the window panel. Multiple universal balls are evenly distributed along the sliding direction of the window panel at the bottom of the long groove and make rolling contact with the protruding strip. External sound-absorbing cotton is installed inside the long groove and makes slidable contact with the groove wall and the protruding strip. The universal balls are located in the perforations of the external sound-absorbing cotton. A support plate is embedded and fixed to the side of the external sound-absorbing cotton facing the bottom of the long groove and is connected to the bottom of the long groove by a spring. A rectangular annular groove is formed at the bottom of the long groove, and a sound-absorbing cotton ring is fixed to the lower end of the external sound-absorbing cotton and is slidably inserted into the annular groove.

[0007] Specifically, the window includes a window frame, with long grooves at both the top and bottom ends of the window frame, and a vacuum glass is fixedly and sealed inside the window frame.

[0008] Specifically, the protrusion is hollow inside and filled with internal sound-absorbing cotton.

[0009] Specifically, sealing strips are fixed to the opposite end faces of the left and right ends of the frame. After the two windows are closed, the windows are in sealed contact with the sealing strips on one side.

[0010] Specifically, a vertical groove is provided at the front end of the rear window frame, close to the center of the frame. A sliding plate is elastically mounted inside the groove, and a sound-absorbing cotton strip is fixed at the front end of the sliding plate. Ear plates are provided on both the upper and lower sides of the rear window frame. The rear end of the ear plates is fixedly connected to the rear pad strip. A guide wheel is rotatably connected to the front end of the ear plates. After the two windows inside the window frame are closed, the sliding plate drives the sound-absorbing cotton strip to press against the rear end face of the front window under the guidance of the guide wheel.

[0011] Specifically, the slide plate is connected to the bottom of the groove by a tension spring.

[0012] Specifically, the end of the sliding plate opposite to the window sliding closing direction is provided with a guide slope.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. The window uses vacuum glass to isolate high-frequency noise. The interior of the raised strip is filled with inner sound-absorbing cotton to absorb mid- and low-frequency noise, while the outer sound-absorbing cotton and sound-absorbing cotton rings further fill the gaps, forming multi-band noise blocking. The outer sound-absorbing cotton is continuously pressed against the raised strip by springs, and the sound-absorbing cotton rings are embedded in the ring grooves. Even if the window is worn down by long-term sliding, it can still adaptively compensate for the gaps, avoiding the sound insulation failure caused by wear in traditional rigid contact.

[0015] 2. The evenly distributed omnidirectional balls within the window's long groove make rolling contact with the raised strips, reducing sliding resistance and minimizing vibration and friction noise between the window and the track. This also prevents the sealing gap from widening due to frictional wear. The sliding plate, through the cooperation of a tension spring and guide wheels, automatically triggers the sound-absorbing cotton strips to compress adjacent windows when the window is closed, achieving active sealing of the gap between the two windows without manual intervention.

[0016] 3. The sliding plate of the rear window is equipped with a guide slope. During the closing process, the guide wheel pushes the sliding plate forward, and the sound-absorbing cotton strip automatically presses against the front window, eliminating the cumbersome operation of manually adjusting the seal after the traditional sliding window is closed. The sealing strips on both sides of the frame, the sound-absorbing cotton strips between the windows, and the sound-absorbing cotton rings together form a three-dimensional sealing network in the horizontal, vertical, and circumferential directions, blocking the noise transmission path.

[0017] 4. The combination of the omnidirectional ball joint and the external sound-absorbing cotton makes the window sliding process quieter, reducing the noise interference caused by friction of traditional metal tracks. Attached Figure Description

[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] Example 1: Refer to Figures 1-3 As shown, a novel noise-reducing window includes a rectangular frame 1. Two tracks are fixed on the opposite ends of the upper and lower sides of the frame 1. The two upper tracks and the two lower tracks are arranged front to back. Two windows are installed inside the frame 1 with staggered front to back arrangements. The windows are slidably connected to the tracks on the upper and lower sides.

[0028] The slide rail includes a pad strip 12 fixedly connected to the frame 1. A protrusion 13 is fixed to one end of the pad strip 12 facing the window. The protrusion 13 is located in the long groove 5 of the window and slides in contact with the window. The protrusion 13 is hollow inside and filled with inner sound-absorbing cotton 4.

[0029] Multiple omnidirectional balls 6 are evenly distributed on the bottom of the long groove 5 along the sliding direction of the window, and the omnidirectional balls 6 make rolling contact with the convex strip 13.

[0030] An external sound-absorbing cotton 7 is installed inside the long groove 5. The external sound-absorbing cotton 7 slides in contact with the groove wall of the long groove 5 and slides in contact with the protrusion 13. The universal ball 6 is located in the perforation of the external sound-absorbing cotton 7. A support plate 8 is embedded and fixed on the side of the external sound-absorbing cotton 7 facing the bottom of the long groove 5. The support plate 8 is connected to the bottom of the long groove 5 by a spring 9.

[0031] The bottom of the long groove 5 is provided with a rectangular annular groove 10, and the lower end of the outer sound-absorbing cotton 7 is fixed with a sound-absorbing cotton ring 11, which is slidably inserted into the annular groove 10.

[0032] The window includes a window frame 2, with elongated grooves 5 at both the top and bottom ends. Vacuum glass 3 is fixedly and sealed inside the window frame 2. The use of vacuum glass 3 in the window improves sound insulation and noise reduction.

[0033] Sealing strips are fixed to the opposite end faces of both ends of frame 1. When both windows are closed, the windows make sealing contact with the sealing strips on one side. After the windows are closed, the sealing strips can improve the sealing effect between the windows and frame 1.

[0034] After the two windows are installed inside the frame 1, a universal ball joint 6 is installed, and the universal ball joint 6 rolls in contact with the convex strip 13 to ensure that the two windows can slide smoothly within the frame 1. The external sound-absorbing cotton 7 and the ring-shaped sound-absorbing cotton can fill the gap between the convex strip 13 and the long groove 5, so that the two windows can achieve a good sound insulation and noise reduction effect when closed. At the same time, the internal sound-absorbing cotton 4 inside the convex strip 13 can further improve the sound insulation and noise reduction effect.

[0035] After the window slides repeatedly within the frame 1, and the outer sound-absorbing cotton 7 wears down, the outer sound-absorbing cotton 7 can press tightly against the protruding strip 13 under the elastic force of the spring 9, ensuring the sound insulation and noise reduction effect after long-term use.

[0036] Example 2: Based on Example 1, referring to... Figures 4-7 As shown, a vertical groove 14 is provided at the front end of the rear window frame 2. The groove 14 is close to the center of the frame 1. A sliding plate 15 is elastically slidably disposed in the groove 14. The sliding plate 15 is connected to the bottom of the groove 14 by a tension spring 17. A sound-absorbing cotton strip 16 is fixed to the front end of the sliding plate 15. Ear plates 18 are provided on both the upper and lower sides of the rear window frame 2. The rear end of the ear plate 18 is fixedly connected to the rear pad strip 12. A guide wheel 19 is rotatably connected to the front end of the ear plate 18. After the two windows inside the window frame 2 are closed, under the guidance of the guide wheel 19, the sliding plate 15 drives the sound-absorbing cotton strip 16 to press against the rear end face of the front window.

[0037] The end of the sliding plate 15 facing away from the window in the direction of sliding closing has a guide slope 20.

[0038] like Figure 4 As shown, Figure 4 The two arrows indicate the sliding closing directions of the two windows. To close the two windows within frame 1, first slide the front window to the left, then slide the rear window to the right. When guide wheel 19 contacts guide ramp 20, slide plate 15 moves sound-absorbing cotton strip 16 forward, stretching spring 17. When the rear window closes, guide wheel 19 contacts the rear end face of slide plate 15. At this point, sound-absorbing cotton strip 16 is pressed tightly against the rear end face of the front window, sealing the gap between the two windows and further improving sound insulation and noise reduction.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
