Abstract
Description
Technical Field
[0001] This utility model belongs to the field of soundproof window technology, specifically relating to a double-layer coupled vibration reduction and noise reduction soundproof window. Background Technology
[0002] In existing technologies, traditional soundproof windows generally use single-pane glass or simple double-glazed structures. While they offer some sound insulation, they are ineffective at blocking low-frequency noise and vibration transmission. Especially in high-noise environments such as main traffic arteries and industrial areas, existing soundproof windows suffer from the following technical defects: First, the window frame and glass are often rigidly connected, lacking an effective vibration buffer structure, leading to a significant sound bridge effect, where sound waves are transmitted through the window frame, generating secondary noise. Second, when dealing with sudden high-decibel noise, existing soundproof windows often generate additional noise due to structural resonance, and the glass panes lack multi-dimensional limiting and buffering devices after installation, making them prone to swaying noise under wind pressure or external forces. These defects severely restrict the actual noise reduction performance and service life of soundproof windows. Therefore, this invention proposes a double-layer coupled vibration-damping and noise-reducing soundproof window to solve these problems. Utility Model Content
[0003] The purpose of this invention is to provide a double-layer coupled vibration-damping and noise-reducing soundproof window that can solve the above-mentioned technical problems.
[0004] The specific technical solution adopted by this utility model is as follows:
[0005] This utility model provides a double-layer coupled vibration reduction and noise reduction sound insulation window, including a window body and a glass sash installed in the window body. The window body is installed at the window opening by expansion bolts. The window body includes four sections, and the corners of adjacent two sections are connected by corner brackets. Each section of the window body includes an inner frame, an outer frame, a middle frame and a side frame.
[0006] The inner frame has a hollow structure and is located on the indoor side of the window opening, while multiple first snap-fit blocks are provided on the outdoor side.
[0007] The outer frame is a hollow structure and is located on the outdoor side inside the window opening, while multiple second snap-fit blocks are provided on the indoor side.
[0008] The middle frame is set between the inner frame and the outer frame, and a third snap-fit block is provided on each of the four corner sides.
[0009] Two horizontal connecting strips are provided between the inner frame and the outer frame. The horizontal connecting strips are locked between the first locking block and the third locking block or between the second locking block and the third locking block.
[0010] The side frame is a folded concave shape and is located on the side near the inner side of the window opening. It is fixedly connected to the outer frame and the inner frame near the window opening. A filler is provided between the side frame and the window opening, and the filler is stuck inside the side frame.
[0011] Preferably, the form also includes two vertical connecting strips and two side connecting strips, one of which is inserted between the first and third connecting blocks corresponding to the inner frame and the middle frame, and the other is inserted between the second and third connecting blocks corresponding to the outer frame and the middle frame.
[0012] Preferably, the two side clip connecting strips are symmetrically arranged and attached to both sides of the glass sash, with their opposite sides clipping onto the two first clip blocks on opposite sides of the outer and inner frames.
[0013] Preferably, the two side clip connecting strips are respectively clipped to the two third clip blocks on the side near the middle frame.
[0014] Preferably, the outer frame is integrally provided with a fixing plate for the side window sash near the side card connecting strip.
[0015] Preferably, the inner frame is provided with a fourth snap-fit block on the side near the side snap-fit connecting strip, and a snap-fit plate for pressing the glass sash is snapped onto the fourth snap-fit block.
[0016] Preferably, the transverse connecting strip, longitudinal connecting strip, and side clip connecting strip are all made of PA66GF25 material, and a heat insulation frame strip is provided inside the middle frame.
[0017] The beneficial effects are:
[0018] 1. This utility model utilizes a combined structure of an inner frame, outer frame, middle frame, transverse connecting strips, and longitudinal connecting strips. This structure creates a suspension bridge effect for the glass pane with the middle frame, while the side-clamping connecting strips buffer the swaying on both sides. This design provides multi-dimensional limiting and buffering of the glass pane's vertical, horizontal, and lateral displacement, thereby reducing resonance noise. Furthermore, the longitudinal, transverse, and side-clamping connecting strips can counteract the sound bridge effect caused by external noise, further improving the noise reduction performance and lifespan of the soundproof window.
[0019] 2. This utility model utilizes a combined structure of an inner frame, an outer frame, a middle frame, heat-insulating strips, horizontal connecting strips, and vertical connecting strips to create multiple sealed chambers on the cross-section of the window. This structure effectively blocks heat conduction and sound wave transmission when dealing with outdoor heat and noise, significantly improving the noise reduction and heat insulation performance of the soundproof window.

[0025] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.
[0026] like Figure 1-3 As shown, a double-layer coupled vibration reduction and noise reduction sound insulation window includes a window body 1 and a glass sash 2 installed inside the window body 1. The window body 1 is installed at the window opening by expansion bolts. The window body 1 includes four sections, and the corners of adjacent sections are connected by corner brackets. Each section of the window body 1 includes an inner frame 11, an outer frame 12, a middle frame 13 and a side frame 14.
[0027] The inner frame 11 has a hollow structure inside and is located on the indoor side of the window opening, while multiple first snap-fit blocks are provided on the outdoor side.
[0028] The outer frame 12 is a hollow structure and is located on the outdoor side inside the window opening, while multiple second snap-fit blocks are provided on the indoor side;
[0029] The middle frame 13 is located between the inner frame 11 and the outer frame 12, and a third snap-fit block is provided on each of the four corner sides;
[0030] Two horizontal connecting strips 16 are provided between the inner frame 11 and the outer frame 12. The horizontal connecting strips 16 are locked between the first locking block and the third locking block or between the second locking block and the third locking block.
[0031] The side frame 14 has a folded concave shape and is located on the side near the inner side of the window opening. It is fixedly connected to the outer frame 12 and the inner frame 11 on the side near the window opening. A filler 15 is provided between the side frame 14 and the window opening, and the filler 15 is stuck inside the side frame 14.
[0032] As an optional implementation, the window 1 also includes two longitudinal connecting strips 17 and two side locking connecting strips 19. One longitudinal connecting strip 17 is locked between the first locking block and the third locking block corresponding to the inner frame 11 and the middle frame 13, and the other longitudinal connecting strip 17 is locked between the second locking block and the third locking block corresponding to the outer frame 12 and the middle frame 13. This allows the outer frame 12 and the inner frame 11 to be longitudinally connected and fastened to the middle frame 13, thereby improving the cushioning when the glass sash 2 shakes.
[0033] See attached document Figure 2 and attached Figure 3 Two side-clamping connecting strips 19 are symmetrically arranged and attached to both sides of the glass fan 2. The opposite sides are clamped onto the two first clamping blocks on the opposite sides of the outer frame 12 and the inner frame 11. In this way, when the glass fan 2 is installed, the opposite sides of the outer frame 12 and the inner frame 11 form a soft contact buffer with the glass fan 2, thereby reducing the noise when the glass fan 2 shakes.
[0034] Furthermore, the two side clip connecting strips 19 are respectively clipped to the two third clip blocks on the side near the middle frame 13. This allows the side clip connecting strips 19 to form a downward pressure buffer when the middle frame 13 is pressed down by the glass sash 2, thereby achieving a shock absorption effect on the glass sash 2.
[0035] Furthermore, the outer frame 12 is integrally provided with a fixing plate 110 for the side-blocking glass sash 2 on the side near the side-blocking connecting strip 19, thereby blocking the outdoor side of the glass during installation and facilitating its installation.
[0036] Furthermore, a fourth snap-fit block is provided on the inner frame 11 near the side snap-fit connecting strip 19, and a snap-fit plate 110a for pressing the glass sash 2 is snapped onto the fourth snap-fit block, thereby facilitating the side snap-fit after the glass sash 2 is installed.
[0037] Furthermore, the transverse connecting strip 16, the longitudinal connecting strip 17, and the side clip connecting strip 19 are all made of PA66GF25 material. This allows the damping characteristics of PA66GF25 material to convert mid-frequency noise vibration energy into heat energy for consumption. At the same time, after connecting the outer frame 12 and the inner frame 11 with the middle frame 13, the overall connection strength is improved, thereby increasing the service life. The middle frame 13 is provided with heat insulation strips 18, which gradually reduces the heat and noise transmitted from the outside, thus reducing the transmission of heat and noise.
[0038] With the above structure, when external noise enters, the cavity structure of the outer frame 12 first reflects and attenuates the high-frequency noise. Then, when the sound wave passes through the elastic connection system composed of the transverse connecting strip 16 and the longitudinal connecting strip 17, the damping characteristics of the PA66GF25 material convert the mid-frequency noise vibration energy into heat energy. Finally, the remaining low-frequency noise is further absorbed in the "suspension bridge-buffer" system formed by the middle frame 13 and the side connecting strip 19, achieving three levels of noise reduction by disrupting the sound bridge effect. In terms of thermal insulation, the air layer formed by the outer frame 12 and the middle frame 13 blocks convective heat transfer, while the thermal insulation frame strip 18 effectively blocks the heat conduction path. Combined with the sealed cavity structure, this significantly reduces the overall heat transfer coefficient. This structure achieves simultaneous noise reduction and thermal insulation, realizing synergistic optimization of acoustic and thermal performance.
