Description

Technical Field

[0001] This invention relates to the field of soundproof curtains, and particularly to a soundproof curtain with optimized sound insulation effect. Background Technology

[0002] Noise levels at the exterior walls of commercial or residential buildings, located approximately 20 meters from the road, can reach 75-80 decibels. Conventional double-glazed casement windows offer only 30-35 decibels of sound insulation, while sliding windows have as low as 15-20 decibels. Furthermore, the sound insulation of casement and sliding windows deteriorates over time, with some reducing their sound insulation to only a few decibels. This sound insulation problem isn't limited to windows; doors also exhibit poor sound insulation.

[0003] Taking windows as an example, methods to improve window sound insulation generally include repairing / replacing the windows or installing soundproof window stickers. Besides these methods, adding soundproof curtains is another option. For instance, Chinese patent CN217501533U discloses a vertical soundproof curtain that uses a sound-insulating layer combined with a sound-absorbing layer to improve sound insulation. It also uses the thickness and surface density of the curtain body to limit the sound insulation effect. Furthermore, during use, the size of the curtain body is selected according to the window opening size, forming a resistive sound-absorbing effect, thus ensuring a certain level of sound insulation. Therefore, it achieves good sound insulation with a simple structure. However, the curtain body is easily affected by uneven walls or airflow, preventing it from achieving optimal acoustic performance. Another example is Chinese patent CN202520208U, where a servo system is connected to the curtain roller, and the curtain's sides are located in side grooves on the window frame, with the bottom of the curtain movably fastened to the bottom groove. However, this setup only provides a sealing effect and does not utilize acoustic principles; it merely provides better fixation for the curtain.

[0004] To improve sound insulation, any abnormal gaps can affect the overall acoustic performance of the soundproof curtain. When the wall opening is a window, a window sill is usually installed at the bottom; when the wall opening is a door, a threshold is usually installed. Both window sills and thresholds are required to be level during construction; however, the levelness achieved during building construction often fails to meet acoustic requirements. Furthermore, there is a possibility of some levelness deviation during the installation of the soundproof curtain. The possibility of abnormal gaps between the counterweight components at the bottom of the curtain and the window sill or threshold is very high. Summary of the Invention

[0005] The main objective of this invention is to provide a soundproof curtain with optimized sound insulation performance, aiming to solve the problem that existing soundproof curtains have poor acoustic performance when installed in wall openings.

[0006] To achieve the above objectives, the present invention provides a soundproof curtain with optimized sound insulation effect, for installation on wall openings in building facades, comprising:

[0007] The drive unit is used to fix the building facade to the exterior and corresponds to the external wall opening structure.

[0008] A curtain element is arranged around the drive unit. The curtain element includes a sound insulation surface layer structure and / or a sound absorption surface layer structure. The curtain element includes a use state where it is rolled out of the drive unit and a storage state where it is rolled up in the drive unit.

[0009] A top seal is arranged parallel to and below the drive unit, wherein the top seal is disposed between the external building facade and the curtain component or on the side of the curtain component facing away from the external building facade;

[0010] Two side guide rail grooves are used to be installed on the building facade on both sides of the external wall opening structure in the height direction. The side guide rail groove includes a base plate and a groove top plate that is parallel to and connected to the outer surface of the base plate. The groove top plate and the base plate form a plate-shaped guide groove that opens towards the wall opening structure. The guide groove has a dimension greater than 10mm in the width direction of the side guide rail groove. When the curtain is in use, its two ends in the width direction extend into the guide groove by 0.2 to 1.0 times the width dimension. The curtain is in close contact with at most one of the two inner walls in the thickness direction of the guide groove. When the curtain is not in close contact with the inner wall in the thickness direction of the guide groove, it forms a sound-absorbing gap with a thickness not exceeding 2mm.

[0011] A counterweight assembly is disposed at one end of the curtain piece away from the drive unit along its length direction. The counterweight assembly includes a counterweight body and an adapter strip connected to the lower part of the counterweight body. The counterweight body and the adapter strip are arranged in parallel, and the angle formed between the length direction of the adapter strip and the length direction of the counterweight body is adjustable.

[0012] Furthermore, the bottom of the cross-section of the adapter strip is perpendicular to the curtain component in use, and the length of the bottom of the cross-section of the adapter strip is 5 to 50 mm.

[0013] Furthermore, the counterweight plate assembly includes a counterweight plate body and an adapter strip. The bottom of the counterweight plate body has an elastic latch that opens downward and extends along the length direction of the counterweight plate body. The cross-section of the adapter strip includes a vertical portion and a horizontal portion connected to the bottom of the vertical portion. The vertical portion is clamped in the elastic latch. The clamping height of the elastic latch on the adapter strip is adjustable. The length of the horizontal portion is 5 to 50 mm, and the height of the vertical portion is 10 to 100 mm.

[0014] Furthermore, the counterweight plate body includes a first drop plate and a second drop plate that are interlocked with each other in the thickness direction, and the elastic latch is formed on the inner side of the bottom of the first drop plate and the second drop plate.

[0015] Furthermore, the top seal is plate-shaped and is installed close to the external building facade.

[0016] Furthermore, the curtain component also includes an operating state between the use state and the storage state. When the curtain component is in the operating state, the curtain component forms the sound-absorbing gap with both inner walls of the guide groove in the thickness direction. When the curtain component is in the use state, the curtain component forms the sound-absorbing gap with one inner wall of the guide groove in the thickness direction and is in close contact with the other inner wall.

[0017] Furthermore, two first magnetic actuators are respectively provided at both ends of the side guide rail groove plate in the length direction, and two second magnetic actuators are provided at intervals in the length direction of the curtain component. When the curtain component is in use, the first magnetic actuators interact with the second magnetic actuators.

[0018] Furthermore, the upper part of the side guide rail groove plate abuts against the top seal in the height direction.

[0019] Furthermore, the top seal is connected to the top of the two side guide rail slots.

[0020] Furthermore, the top plate of the groove is connected to the middle part of the substrate in the width direction.

[0021] Furthermore, the counterweight plate assembly has sliding mating parts at both ends along its length, the sliding mating parts extending into the guide groove, and the thickness of the sliding mating parts matching the thickness of the guide groove.

[0022] Furthermore, the back of the side guide rail groove plate is provided with at least one first sealing strip arranged along its length direction, the top sealing member is plate-shaped and closely attached to the external building facade, and the back of the top sealing member is provided with at least one second sealing strip arranged along its length direction.

[0023] Furthermore, the thickness of the fabric component is 1 to 10 mm, and the areal density of the fabric component is 1.5 to 3.0 kg / m². 2 The curtain component includes at least one layer of the sound insulation surface layer structure and at least one layer of the sound absorption surface layer structure.

[0024] The soundproof curtain with optimized sound insulation provided by this invention has side guide rail grooves set on both sides of the curtain fabric in the width direction. These guide rails guide the curtain fabric in both rolling out and rolling up. By increasing the width of the guide grooves on the side guide rails and forming a sound-absorbing gap between the curtain fabric and the inner wall of the guide grooves, the sound insulation effect is ensured. Furthermore, by adjusting the fixing angle of the adapter strip on the counterweight plate, the bottom of the adapter strip can achieve the required dimensional matching effect with the bottom of the wall opening structure, thus guaranteeing the sound insulation effect.

[0044] Reference Figures 1 to 15In one embodiment of the present invention, a soundproof curtain with optimized sound insulation effect is used to be installed on the wall opening structure 020 of the building facade 010, comprising:

[0045] The drive unit 100 is fixed to the external building facade 010 and is provided corresponding to the external wall opening structure 020;

[0046] A curtain element 200 is arranged around the drive unit 100. The curtain element 200 includes a sound insulation surface layer structure and / or a sound absorption surface layer structure. The curtain element 200 includes a use state where it is rolled out of the drive unit 100 and a storage state where it is rolled up in the drive unit 100.

[0047] A top seal 300 is arranged parallel to and below the drive unit 100, wherein the top seal 300 is disposed between the external building facade 010 and the curtain 200 or disposed on the side of the curtain 200 facing away from the external building facade 010.

[0048] Two side guide rail grooves 400 are used to be installed on the building facades 010 on both sides of the external wall opening structure 020 in the height direction. The side guide rail groove 400 includes a base plate 410 and a groove top plate 420 that is parallel to and connected to the outer surface of the base plate 410. The groove top plate 420 and the base plate 410 form a plate-shaped guide groove 430 that opens towards the wall opening structure 020. The guide groove 430 has a width dimension greater than 10mm in the side guide rail groove 400. When the curtain 200 is in use, its two ends in the width direction extend into the guide groove 430 by 0.2 to 1.0 times the width dimension. The curtain 200 is in close contact with at most one of the two inner walls in the thickness direction of the guide groove 430. When the curtain 200 is not in close contact with the inner wall in the thickness direction of the guide groove 430, it forms a sound-absorbing gap with a thickness not exceeding 2mm.

[0049] A counterweight plate assembly 500 is disposed at one end of the curtain 200 away from the drive unit 100 along its length. The counterweight plate assembly 500 includes a counterweight plate body 510 and an adapter strip 520 connected to the lower part of the counterweight plate body 510. The counterweight plate body 510 and the adapter strip 520 are arranged in parallel, and the angle formed between the length direction of the adapter strip 520 and the length direction of the counterweight plate body 510 is adjustable.

[0050] In existing technology, the guide rails on both sides of the curtain do not use acoustic principles for their function; they merely provide better fixation and restriction for the curtain. Furthermore, it is difficult to achieve the required acoustic effect during the construction of either the windowsill or the threshold stone, and there is a high probability that the gap between the counterweight component at the bottom of the curtain and the windowsill or threshold stone will be abnormal.

[0051] In this invention, the soundproof curtain is set in a wall opening structure 020 (which can be a door opening or a window opening, etc.). Specifically, the wall opening structure 020 is set on the building facade 010. Since the use of the soundproof curtain in this invention utilizes gravity, the environment in which it is used is limited to the building facade 010.

[0052] The drive unit 100 is fixed to the external building facade 010 and positioned above the external wall opening structure 020. The drive unit 100 specifically includes a support base and a roller structure fixed to the support base, which secures the subsequent curtain element 200. The driving force of the roller structure can be a motor or manual operation.

[0053] The curtain element 200 is enclosed in the drive unit 100. The curtain element 200 includes a sound-insulating surface layer structure and / or a sound-absorbing surface layer structure. The number of sound-insulating or sound-absorbing surface layer structures is not limited to one layer. The sound-insulating surface layer structure can be a damping sound-insulating blanket, etc., and the sound-absorbing surface layer structure can be a microporous sound-absorbing blanket, etc. The thickness of the curtain element 200 is not specifically limited and can be 1 to 10 mm (thicker thicknesses are not conducive to rolling up and are mainly for large-scale applications), with the aim of achieving a certain level of sound insulation and sound absorption. The surface density of the curtain element 200 is 1.0 to 4.0 kg / m², and the curtain element 200 includes at least one sound-insulating surface layer structure and at least one sound-absorbing surface layer structure. The curtain element 200 can be composed of multiple sound-insulating surface layer structures and multiple sound-absorbing surface layer structures stacked together, or the outermost layer of the curtain element 200 can also be a decorative surface layer. The curtain component 200 includes a usage state where it is rolled out of the drive unit 100 and a storage state where it is rolled up in the drive unit 100.

[0054] The top seal 300 is arranged parallel to and below the drive unit 100, primarily to ensure the acoustic performance of the curtain 200 above the wall opening structure 020. Specifically, depending on the design type, the top seal 300 may be positioned between the external building facade 010 and the curtain 200, or on the side of the curtain 200 facing away from the external building facade 010. In both cases, contact between the curtain 200 and the top seal 300 is not required, as long as sound insulation is ensured. When the top seal 300 presses the curtain 200 against the external building facade 010, the advantage is that regardless of the distance between the curtain 200 and the building facade 010 when it is fixed to the drive unit 100, it will be pressed against the building facade 010 at the top seal 300, forming a sound insulation effect.

[0055] When the top seal 300 supports the curtain 200 detached from the external building facade 010, the acoustic sealing conditions formed between the top seal 300 and the building facade 010 are good. Of course, the tight fit between the curtain 200 and the top seal 300 can be achieved through the side guide rail groove plate 400.

[0056] Two side guide rail grooves 400 are installed on the building facades 010 on both sides of the external wall opening structure 020 in the height direction. The side guide rail grooves 400 extend vertically and guide the curtain 200 during its roll-out and roll-up processes while also ensuring sound insulation. Each side guide rail groove 400 includes a base plate 410 and a groove top plate 420 parallel to and connected to the outer surface of the base plate 410. The groove top plate 420 and the base plate 410 form a plate-shaped guide groove 430 that opens towards the wall opening structure 020. Generally, the thickness of the guide groove 430 is 1 to 5 mm, but this thickness should not be limited. Specifically, its thickness is designed to accommodate the thickness of the curtain 200 to create a dimensionally acceptable sound-absorbing gap. When the curtain element 200 is in use, it forms a sound-absorbing gap with both inner walls of the guide groove 430 in the thickness direction, or forms a sound-absorbing gap with only one inner wall while being in close contact with the other inner wall. The thickness of the sound-absorbing gap does not exceed 2mm. The guide groove 430 has a width dimension of 10 to 100mm in the side guide rail groove plate 400 (in extreme cases such as large buildings, the width dimension can still be increased). When the curtain element 200 is in use, both ends of its width direction extend into the two guide grooves 430 respectively, and the dimension of both ends of the curtain element 200 extending into the guide grooves 430 in the width direction is 0.2 to 1.0 times the width dimension of the guide groove 430. A sound-absorbing gap with a thickness of 0.01 to 2mm is formed between the curtain element 200 and the front and rear sides of the guide groove 430 in the thickness direction. The sound-absorbing gap formed between the curtain element 200 and the guide groove 430 in the thickness direction achieves both resistive and reactive sound absorption effects.

[0057] The counterweight assembly 500 is located at the end of the curtain 200 away from the drive unit 100 along its length, providing load-bearing capacity and improving the drape of the curtain 200. The counterweight assembly 500 and the curtain 200 can be connected in various ways, including through screws or similar structures, adhesive bonding, snap-fitting, clamping, etc. By adjusting the fixing angle of the adapter strip 520 on the counterweight body 510, the bottom of the adapter strip 520 can achieve the required dimensional matching with the bottom of the wall opening structure 020, ensuring sound insulation. Specifically, the fixing method of the adapter strip 520 on the counterweight body 510 can be varied, depending on whether adjustment is possible; the fixing method can include screw connection, adhesive bonding, hook and loop fastener connection, magnetic connection, etc. The counterweight assembly 500 is positioned along the width direction of the curtain, and whether it extends into the guide groove 430 is not restricted; the specific setting depends on the thickness of the counterweight assembly 500.

[0058] In this embodiment, the curtain fabric 200 has a 2mm thick sound-absorbing surface layer, a 2mm thick sound-insulating surface layer, and a 2mm thick sound-absorbing surface layer, respectively, from the outer side to the inner side. The surface density of the curtain body is 2.5KG / m². 2 The sound insulation of the installed soundproof curtain was tested. In use, the curtain 200 was tightly attached to the inner wall of the guide groove 430 on one side in the thickness direction, while forming a 1mm thick sound-absorbing gap with the inner wall of the guide groove 430 on the other side in the thickness direction. The guide groove 430 has a width dimension of 40mm in the side guide rail groove plate 400. Both ends of the curtain 200 in the width direction extend into the guide groove 430 by 0.9 times the width dimension. The measuring instrument was a Danish Bruel & Kiaer-0 handheld spectrum analyzer, which can achieve a sound insulation effect of about 19 dB under full-frequency noise, forming a full-frequency sound insulation structure, while also having the effects of light blocking, heat insulation, and heat preservation.

[0059] In summary, the side guide rail grooves 400 are located on both sides of the curtain fabric 200 in the width direction. They guide the curtain fabric 200 in both rolling out and rolling up. By increasing the width of the guide groove 430 of the side guide rail grooves 400 and forming a sound-absorbing gap between the curtain fabric 200 and the inner wall of the guide groove 430, the sound insulation effect is ensured. By adjusting the fixing angle of the adapter strip 520 on the counterweight plate body 510, the bottom of the adapter strip 520 can achieve the required size matching effect with the bottom of the wall hole structure 020, thus ensuring the sound insulation effect.

[0060] Reference Figure 12 In one embodiment, the bottom of the cross-section of the adapter strip 520 is perpendicular to the curtain member 200 in use, and the bottom length of the cross-section of the adapter strip 520 is 5 to 50 mm.

[0061] In this embodiment, the bottom of the adapter strip 520's cross-section is perpendicular to the curtain element 200 in use, and the length of the adapter strip 520 is limited, resulting in better performance of the adapter strip 520. There are two usage modes: the first is that the bottom of the adapter strip 520 contacts the bottom of the wall opening structure 020 to form a seal; the second is that the bottom of the adapter strip 520 forms a gap of 0.5 to 1.5 mm with the bottom of the wall opening structure 020. These gaps simultaneously achieve both resistive and damping sound absorption effects. In particular, since the adapter strip 520 does not contact the bottom of the wall opening structure 020, the possibility of the curtain element 200 making abnormal contact with the guide groove 430 during descent is low. The required gap size between the bottom of the adapter strip and the bottom of the wall opening structure 020 can be achieved by limiting the length of the curtain element 200.

[0062] Reference Figures 12 to 14 In one embodiment, the counterweight plate assembly 500 includes a counterweight plate body 510 and an adapter strip 520. The bottom of the counterweight plate body 510 has an elastic latch 511 that opens downward and extends along the length direction of the counterweight plate body 510. The cross-section of the adapter strip 520 includes a vertical portion and a horizontal portion connected to the bottom of the vertical portion. The vertical portion is clamped in the elastic latch 511. The clamping height of the elastic latch 511 on the adapter strip 520 is adjustable. The length of the horizontal portion is 5 to 50 mm, and the height of the vertical portion is 10 to 100 mm.

[0063] In this embodiment, a simple, convenient, and reliable method for fixing the adapter strip 520 is provided. The bottom of the counterweight plate body 510 has an elastic latch 511 that opens downwards and extends along the length of the counterweight plate body 510. The adapter strip 520 is clamped in the elastic latch 511, and the clamping height of the elastic latch 511 on the adapter strip 520 is adjustable. By adjusting the left and right height of the elastic latch 511, the counterweight plate assembly 500 can achieve the required sealing effect with the bottom of the wall opening structure. The adjustable clamping height of the elastic latch 511 on the adapter strip 520 requires that the adapter strip 520 have a certain height dimension and the elastic latch 511 have a certain depth dimension. Specifically, the cross-section of the adapter strip 520 can be "T" shaped or "Г" shaped, etc.

[0064] Reference Figures 12 to 13 In one embodiment, the counterweight plate body 510 includes a first drop plate and a second drop plate that are interlocked with each other in the thickness direction, and the elastic latch 511 is formed on the inner side of the bottom of the first drop plate and the second drop plate.

[0065] In this embodiment, dividing the counterweight plate body 510 into a first drop plate and a second drop plate facilitates processing and forming. At the same time, the snapping process of the first drop plate and the second drop plate can also achieve clamping of the curtain piece 200, which greatly reduces the difficulty of fixing the curtain piece 200.

[0066] In one embodiment, the top seal 300 is plate-shaped and is disposed in close contact with the external building facade 010.

[0067] In this embodiment, due to the presence of the guide groove 430, when the top seal 300 is tightly attached to the external building facade 010, the curtain element 200 will not excessively detach from the top seal 300. Therefore, firstly, the top seal 300 forms a tight connection with the wall, thus ensuring a certain degree of sound insulation between the two, especially since a sealing strip can also be installed on the back of the top seal 300; secondly, through the thickness setting, the top seal 300 can serve as a position guide for the curtain element 200, ensuring the positional relationship between the curtain element 200 and the guide groove 430 in the thickness direction, thereby guaranteeing the acoustic effect. During use, the curtain element 200 can be set tightly against the top seal 300 in the thickness direction, or there can be a gap of 0.01 to 2 mm between them. When set tightly against the top seal 300, the sound insulation effect is better, but the frictional resistance between the curtain element 200 and the top seal 300 is greater. When a certain gap is provided, resistive and reactive sound attenuation can be utilized, ensuring the sound insulation effect of the curtain element 200 at that location without generating frictional resistance. It should be noted that when a gap is provided between the curtain element 200 and the top seal 300, the width of the top seal 300 itself can be set larger (e.g., 20 mm or more) to enhance the sound insulation effect.

[0068] In one embodiment, the curtain component 200 also includes an operating state between a use state and a storage state. When the curtain component 200 is in the operating state, the curtain component 200 and the inner walls on both sides of the guide groove 430 in the thickness direction form the sound-absorbing gap. When the curtain component 200 is in the use state, the curtain component 200 and the inner wall on one side of the guide groove 430 in the thickness direction form the sound-absorbing gap and are in close contact with the inner wall on the other side.

[0069] In this embodiment, the above settings ensure that the curtain 200 will not rub against the inner wall of the guide groove 430 during the lowering process. When the curtain 200 is in use, it is in close contact with the inner wall of the guide groove 430 on one side in the thickness direction, thus ensuring the sound insulation effect of the curtain 200 when it is in use.

[0070] In one embodiment, two first magnetic actuators are respectively provided at both ends of the side guide rail groove plate 400 along its length, and two second magnetic actuators are provided at intervals along the length of the curtain component 200. When the curtain component 200 is in use, the first magnetic actuators interact with the second magnetic actuators.

[0071] In this embodiment, a simple and practical structural implementation is provided, in which the state of the guide groove 430 changes during the lowering of the curtain component 200. Specifically, when the curtain component 200 is not in the usage state, the first magnetic actuating element and the second magnetic actuating element are not aligned and do not interact with each other, so the curtain component 200 is located in the middle of the thickness direction of the guide groove 430; while when the curtain component 200 reaches the usage state, the first magnetic actuating element and the second magnetic actuating element are aligned and magnetic interaction occurs, at which time the curtain component 200 is tightly attached to one side of the inner wall of the guide groove 430 in the thickness direction. The first magnetic actuating element and the second magnetic actuating element can attract or repel each other, and there is no specific limitation. For example, the first magnetic actuating element can be a magnetic material, while the second magnetic actuating element can be a magnetizable material (such as multiple iron wires with small diameters, arranged along the width direction of the curtain component 200, thereby ensuring that the curtain component 200 can be rolled up); or both the first magnetic actuating element and the second magnetic actuating element are magnetic materials. It should be noted that the interaction between the first magnetic actuator and the second magnetic actuator can be mechanically designed so as not to interfere with the downward process of the curtain component 200.

[0072] In one embodiment, the upper part of the side guide rail groove plate 400 in the height direction abuts against the top seal 300.

[0073] In this embodiment, the side guide rail groove plate 400 abuts against the top sealing member 300, forming a seal between them. Specifically, during construction, adhesive can be applied between them to improve the sealing effect.

[0074] In one embodiment, the top seal 300 is connected to the top of the two side guide rail grooves 400.

[0075] In this embodiment, the top seal 300 and the two side guide rail grooves 400 are integrated into a single unit, which has various advantages. For example, the top seal 300 can serve as a guide for the installation height of the two side guide rail grooves 400 (or vice versa) or for the installation spacing of the two side guide rail grooves 400.

[0076] In one embodiment, the drive unit 100 is interconnected with the top seal 300.

[0077] In this embodiment, the drive unit 100 and the top seal 300 are interconnected, which ensures the proper installation position of the top seal 300 relative to the drive unit 100. When the curtain element 200 and the top seal 300 are in contact, a good sealing effect is achieved. If the top seal 300 is connected to the top of the two side guide rail grooves 400, the drive unit 100, the top seal 300, and the two side guide rail grooves 400 can form a single unit, thus ensuring both accuracy and convenience of installation.

[0078] Reference Figures 7 to 10 In one embodiment, the slot top plate 420 is connected to the middle portion of the substrate 410 in the width direction.

[0079] In this embodiment, the groove top plate 420 starts from the middle of the width direction of the substrate 410, so the side of the substrate 410 away from the guide groove 430 in the width direction can serve as the fixing base of the screw structure.

[0080] Reference Figures 7 to 10 In one embodiment, the front side of the substrate 410 has a screw groove 411 on the side away from the top plate 420 in the width direction, and a pressure plate 412 is detachably provided corresponding to the screw groove 411.

[0081] In this embodiment, a fixing structure for the side guide rail slot plate 400 is provided. Screw slots 411 and guide slots 430 are arranged in parallel, and a pressure plate 412 is detachably provided corresponding to the screw slots 411. During the fixing of the screw slots 411, the pressure plate 412 is removed, and the fixing screws are positioned within the screw slots 411. Specifically, the fixing screws pass through the base plate 410 to fix the side guide rail slot plate 400 to the building facade 010, and then the pressure plate 412 is installed into the screw slots 411. The connection method between the pressure plate 412 and the screw slots 411 can be selected according to the situation, preferably a snap-fit ​​connection. Compared to the previous embodiment, the screws are enclosed and made invisible by the arrangement of the screw slots 411 and the pressure plate 412.

[0082] In one embodiment, the counterweight plate assembly 500 has sliding mating parts at both ends along its length, the sliding mating parts extending into the guide groove 430, and the thickness of the sliding mating parts matching the thickness of the guide groove 430.

[0083] In this embodiment, the introduction of the sliding fit portion ensures accurate positioning during the rising and falling of the counterweight plate assembly 500. This results in a more precise position of the curtain fabric 200 relative to the guide groove 430, guaranteeing the sound insulation effect between the curtain fabric 200 and the guide groove 430. The specific structure of the sliding fit portion can be varied; it can be integrally formed into the counterweight plate assembly 500 or subsequently connected to it. For example, the sliding fit portion can be a plastic block inserted into the end face of the counterweight plate assembly 500 along its length.

[0084] Reference Figure 4 , 7 In one embodiment, the back of the side guide rail groove plate 400 is provided with at least one first sealing strip 600 arranged along its length direction, the top sealing member 300 is plate-shaped and closely attached to the external building facade 010, and the back of the top sealing member 300 is provided with at least one second sealing strip 700 arranged along its length direction.

[0085] In this embodiment, the sound insulation effect between the side guide rail groove plate 400 and the building facade 010 is ensured by the setting of the first sealing strip 600 on the side guide rail groove plate 400. The material of the first sealing strip 600 can be various polymer materials, preferably rubber (such as polyurethane). The connection method of the first seal on the side guide rail groove plate 400 is also diverse, such as bonding, and preferably snap-fit ​​or nail-fit that does not produce volatile chemical harmful gases. For example, during the molding process of the side guide rail groove plate 400, a snap-fit ​​for securing the first sealing strip 600 is directly formed on the back of the side guide rail groove plate 400 by the design of the mold. Preferably, there are two first sealing strips 600, which are respectively set at both ends of the width direction of the side guide rail groove plate 400. The sound insulation effect between the top sealing member 300 and the building facade 010 is ensured by the setting of the second sealing strip 700 on the top sealing member 300. The material of the second sealing strip 700 can be various polymer materials, preferably rubber (such as polyurethane). The connection method of the second seal on the top seal 300 is also diverse, such as bonding, etc. Preferred methods are snap-fit ​​or nail-fit, which do not produce volatile chemical harmful gases. For example, during the molding process of the top seal 300, the back of the top seal 300 is directly molded with a snap-fit ​​for securing the second sealing strip 700 through the design of the mold.

[0086] Reference Figures 7 to 10 The thickness of the curtain fabric 200 is 1 to 8 mm, and the areal density of the curtain fabric 200 is 1.5 to 3.0 kg / m². 2 The curtain component 200 includes at least one layer of the sound insulation surface layer structure and at least one layer of the sound absorption surface layer structure.

[0087] In this embodiment, firstly, the curtain component 200 is limited to include a sound-insulating surface layer structure and a sound-absorbing surface layer structure, so that the curtain component 200 has both a certain sound insulation effect and a sound absorption effect. Then, the thickness and surface density of the curtain component 200 are further limited to achieve a better acoustic effect, especially since surface density has a significant impact on acoustic characteristics.

[0088] In summary, the soundproof curtain with optimized sound insulation provided by the present invention has side guide rail grooves 400 disposed on both sides of the curtain fabric 200 in the width direction. These guide rails guide the curtain fabric 200 during its roll-out and roll-up actions. Furthermore, by increasing the width of the guide groove 430 of the side guide rail grooves 400 and forming a sound-absorbing gap between the curtain fabric 200 and the inner wall of the guide groove 430, the sound insulation effect is ensured. By adjusting the fixing angle of the adapter strip 520 on the counterweight plate body 510, the bottom of the adapter strip 520 can achieve the required dimensional matching effect with the bottom of the wall opening structure 020, thus guaranteeing the sound insulation effect.

[0089] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
