Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of door and window devices, in particular to a sound insulation and noise reduction window. Background Art
[0002] Soundproof windows are a type of window specially designed to improve indoor quietness in modern homes. The core design of this type of window lies in its unique glass structure and frame sealing method, which work together to effectively reduce the entry of external noise.
[0003] Soundproof windows usually use double or triple layers of glass, and the transmission of sound waves is significantly reduced by evacuating the glass layers. When sound waves encounter a vacuum layer, their propagation will be greatly hindered because sound needs to pass through a medium to propagate, and there is no medium for sound waves to propagate in a vacuum environment. This design allows soundproof windows to effectively isolate high-frequency and low-frequency noise from the outside world.
[0004] In order to ensure the soundproof effect of the soundproof window, high-quality sealing strips or sealing rings are used to seal between the glass and the frame. The function of these sealing strips or sealing rings is to prevent air from entering the vacuum cavity, because once air enters, the vacuum layer will be destroyed, thus affecting the soundproof effect.
[0005] However, the performance of the sealing strip or seal ring will be affected by the change of the external environment temperature. As the temperature changes, the sealing strip will expand and contract. When the temperature rises, the sealing strip will expand and contact the glass and window frame more closely, thus maintaining its good sealing. In this case, the sound insulation effect of the soundproof window will not be greatly affected.
[0006] However, when the temperature drops, the seal shrinks. At this time, tiny gaps may appear between the seal and the glass and frame. Although these gaps are small, they are enough to allow air to enter the cavity that is supposed to be a vacuum, thus destroying the vacuum layer and causing the soundproofing effect of the soundproof window to decrease. This effect may be more obvious in the cold winter. Summary of the invention

[0023] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.
[0024] like Figure 1 , 2 As shown in FIG. 5 , the utility model includes a frame 1 , a soundproof glass 2 , a first sealing ring 5 , a second sealing ring 4 and a pre-tightening mechanism 3 .
[0025] The inner wall of the frame 1 is provided with a mounting groove, which is a rectangular ring structure, in which three layers of soundproof glass 2 are installed, a vacuum layer is provided between two adjacent soundproof glass 2, and two symmetrically distributed sealing grooves are provided on the bottom of the mounting groove, which are located between two adjacent soundproof glass 2. The two soundproof glass 2 located outside the frame 1 are connected to the groove wall of the mounting groove through the first sealing ring 5 respectively.
[0026] A second sealing ring 4 is installed in the sealing groove. The second sealing ring 4 is in close contact with two adjacent soundproof glasses 2. A pre-tightening groove is provided at the outer end of the second sealing ring 4. A pre-tightening mechanism 3 is installed in the pre-tightening groove.
[0027] like Figure 3 and 4As shown, the pre-tightening mechanism 3 includes a clamping plate 31, a first guide plate 32 and a spring 33. Two clamping plates 31 are installed between the two sealing rings. One end of the two clamping plates 31 is respectively pressed against the groove wall of the pre-tightening groove corresponding to the sealing ring. The corresponding ends of the two clamping plates 31 are provided with inclined surfaces. A first guide plate 32 is installed between the two clamping plates 31. Both ends of the first guide plate 32 are respectively provided with inclined surfaces corresponding to the inclined surfaces of the clamping plates 31. The first guide plate 32 is connected to the groove bottom of the sealing groove through a spring 33. The spring 33 is compressed, and the spring 33 presses the inclined surface of the first guide plate 32 against the inclined surface of the clamping plate 31, so that the two fit each other. When the sealing ring shrinks and becomes thinner, the spring 33 drives the guide plate to squeeze the two clamping plates 31, so that the two clamping plates 31 expand to both sides and squeeze the second sealing ring 4 to prevent the generation of gaps.
[0028] In this embodiment, the pre-tightening mechanism 3 is divided into four parts. The second sealing ring 4 includes upper and lower sealing strips and two side sealing strips. Each part of the pre-tightening mechanism 3 corresponds to a sealing strip, and the sealing strip can be expanded and pre-tightened.
[0029] like Figure 6 and 7 As shown, the upper and lower end walls and the two side walls of the frame 1 are respectively provided with long strip guide cavities, a plurality of connecting holes are provided between the long strip guide cavity and the sealing groove, a second guide plate 34 is installed inside the long strip guide cavity, the second guide plate 34 is slidably matched with the long strip guide cavity, and the spring 33 passes through the connecting hole and is connected to the second guide plate 34.
[0030] In the optimized solution, two symmetrically distributed guide rods 36 are fixedly installed in the long strip guide cavity, and guide holes are respectively provided at both ends of the second guide plate 34. The guide rods 36 pass through the guide holes of the second guide plate 34, and the two are slidably matched.
[0031] A threaded through hole is provided on the outer end wall of the elongated guide cavity, and the threaded through hole is threadedly matched with the adjusting stud 35. The outer end of the adjusting stud 35 is provided with a hexagonal blind hole, and the inner end is pressed against the outer end of the second guide plate 34. A hexagonal wrench is inserted into the hexagonal blind hole, and the adjusting stud 35 is rotated to adjust the compression amount of the spring 33 and the pressure of the clamping plate 31 on the second sealing ring 4.
[0032] The operation process is as follows: when the sealing ring of the utility model is affected by external conditions and shrinks, the spring 33 drives the first guide plate 32 to squeeze the two clamping plates 31, so that the two clamping plates 31 expand to both sides and squeeze the groove wall of the pre-tightening groove of the second sealing ring 4. The clamping plate 31 squeezes the outer end soundproof glass 2 through the second sealing ring 4, and at the same time, the outer end soundproof glass 2 can squeeze the first sealing ring 5 at the same time, thereby preventing the generation of gaps.
[0033] It should be noted that the specific embodiments of the present invention have been described in detail. For those skilled in the art, various obvious changes to the present invention without departing from the spirit and scope of the present invention are within the protection scope of the present invention.
