[0020] Compared with the prior art, the sound insulation structure of the present invention has at least the following advantages:

[0021] 1. In the sound insulation structure of the present invention, the bottom of an openable soundproof door, an openable soundproof window or other openable building is sealed by the coordinated use of the sliding seat, the lifting mechanism and the sealing mechanism.

When the sliding assembly slides into the accommodating cavity, the sliding seat and the sealing mechanism are not supported by the lifting mechanism, so that the sliding seat and the sealing mechanism move downward due to gravity and fit tightly with the floor, the counter-sill or the wall, effectively preventing outdoor noise from directly entering the room through the gap at the bottom, thereby improving the sound insulation effect.

[0022] 2. In the sound insulation structure of the present invention, the sliding assembly passes through the sliding seat, and both ends of the sliding assembly are slidably connected to the sliding seat, that is, the sliding assembly and the lifting assembly directly support the sliding seat and the sealing mechanism as a whole, thereby improving the supporting stability of the sliding assembly and the lifting assembly on the sliding seat and the sealing mechanism, and making it difficult for the sliding seat to fall off the sliding assembly, thereby improving the structural stability of the sound insulation structure.

The sealing mechanism is connected to the sliding seat, and the sealing mechanism is located on the side where the sliding seat slides away from the slide groove. Among them, when the telescopic assembly is compressed, the sliding assembly slides toward the accommodating chamber, and the sliding seat is driven by gravity to drive the sealing mechanism downward; when the telescopic assembly is released, the sliding assembly slides away from the accommodating chamber, and the sliding seat is supported by the lifting assembly to drive the sealing mechanism upward.

The invention relates to a method for improving the ease of movement of the sound insulation structure by providing a plurality of movable parts, such as a plurality of movable parts, a plurality of movable parts, and a plurality of movable parts, wherein the movable parts are provided with a plurality of movable parts, and a plurality of movable parts are provided with ...

[0042] Please also refer to 1. Figure 3 and Figure 6To better understand the sound insulation structure 10 of the present invention, the following further describes the sound insulation structure 10 of the present invention. In one embodiment, the sound insulation structure 10 includes a sliding seat 100, a lifting mechanism 200, and a sealing mechanism 300. The sliding seat 100 is positioned within a slide groove 31 and is slidably connected to the mounting seat 30. The sliding seat 100 defines a sliding hole 110 and a receiving cavity 120 that communicate with each other. The sliding hole 110 communicates with the slide groove 31. The lifting mechanism 200 includes a sliding assembly 210, a telescopic assembly 220, and a lifting assembly 230. The sliding assembly 210 is disposed within the sliding hole 110 and is slidably connected to the sliding seat 100. The sliding assembly 210 is also slidably connected to the mounting seat 30. The telescopic assembly 220 is located within the accommodating cavity 120 and is sleeved onto the sliding assembly 210. The ends of the telescopic assembly 220 abut against the mounting seat 30 and the sliding assembly 210, respectively. The lifting assembly 230 is connected to the sliding assembly 210 and is also connected to at least one of the sliding seat 100 and the mounting seat 30. The lifting assembly 230 is used to adjust the relative connection position between the sliding seat 100 and the mounting seat 30 when the sliding assembly 210 slides relative to the sliding seat 100. The sealing mechanism 300 is connected to the sliding seat 100 and is located on the side of the sliding seat 100 facing the notch of the slide groove 31. When the telescopic assembly 220 is compressed, the sliding assembly 210 slides toward the accommodating cavity 120, and the sliding seat 100 is driven by gravity to drive the sealing mechanism 300 downward, so that the sealing mechanism abuts against the floor, the sill or the wall. At this time, the sound insulation structure 10 plays a sound insulation role; when the telescopic assembly 220 is released, the sliding assembly 210 slides away from the accommodating cavity 120, and the sliding seat 100 is supported by the telescopic assembly 220 to drive the sealing mechanism 300 upward, so that the sealing mechanism leaves the floor, the sill or the wall.

[0043] In the above-mentioned sound insulation structure 10, the mounting seat 30 can be a portion of a structure such as a door or window for mounting the sound insulation structure, ensuring the connection stability of the sound insulation structure when in use. The bottom of the sound insulation door is sealed by the cooperation of the sliding seat 100, the lifting mechanism 200, and the sealing mechanism 300. When the telescopic assembly 220 is compressed, the sliding assembly 210 slides toward the accommodating chamber 120, and the sliding seat 100 is driven downward by gravity to move the sealing mechanism 300. When the telescopic assembly 220 is released, the sliding assembly 210 slides away from the accommodating chamber 120, and the sliding seat 100 is supported by the telescopic assembly 220 to drive the sealing mechanism 300 upward. That is, when the sliding assembly 210 slides away from the accommodating chamber 120, the sliding seat 100 and the sealing mechanism 300 are supported by the lifting mechanism 200 and leave the floor, sill, or other similar structure. The wall prevents the sliding seat 100 and the sealing mechanism 300 from moving downward due to gravity and contacting the floor, counter-sill or wall, which increases the friction between the sealing mechanism 300 and the floor, counter-sill or wall during the activity, resulting in increased activity resistance, thereby improving the convenience of activity; when the sliding assembly 210 slides toward the accommodating cavity 120, the sliding seat 100 and the sealing mechanism 300 are not supported by the lifting mechanism 200, so that the sliding seat 100 and the sealing mechanism 300 move downward due to gravity and fit tightly with the floor, counter-sill or wall, effectively preventing outdoor noise from directly entering the room from the gap at the bottom, thereby improving the sound insulation effect. The sliding assembly 210 is inserted into the sliding seat 100, and both ends of the sliding assembly 210 are slidably connected to the sliding seat 100, that is, the sliding assembly 210 and the lifting assembly 230 directly support the sliding seat 100 and the sealing mechanism 300 as a whole, thereby improving the supporting stability of the sliding assembly 210 and the lifting assembly 230 on the sliding seat 100 and the sealing mechanism 300, and making it difficult for the sliding seat 100 to fall off the sliding assembly 210, thereby improving the structural stability of the sound insulation structure 10.

[0044] It is understandable that, in order to reduce the gap at the bottom of the openable soundproof door, openable soundproof window or other openable building, and thus reduce the outdoor noise directly transmitted into the room through the gap in the door, on the openable soundproof door, openable soundproof window or other openable building, if the gap between the openable soundproof door, openable soundproof window or other openable building and the floor, sill or threshold is directly blocked by a fixed seal, the movement resistance of the openable soundproof door, openable soundproof window or other openable building will be greatly increased, and debris will easily accumulate at the sealing mechanism 300, further increasing the movement resistance of the openable soundproof door, openable soundproof window or other openable building. force, causing inconvenience in opening and closing of openable soundproof doors, openable soundproof windows or other openable buildings. Therefore, more often, the composition of openable soundproof doors, openable soundproof windows or other openable buildings will be improved to enhance the sound insulation performance and reduce the defects caused by the poor sealing effect of the soundproof doors. However, improving the composition of openable soundproof doors, openable soundproof windows or other openable buildings will increase the thickness and weight of the openable soundproof doors, openable soundproof windows or other openable buildings, and also cause inconvenience in opening and closing of the openable soundproof doors, openable soundproof windows or other openable buildings, and the sound insulation effect achieved is also poor. Therefore, the present invention focuses on improving the sound insulation effect of openable soundproof doors, openable soundproof windows or other openable buildings, and focuses on improving the sealing of the bottom of the openable soundproof doors, openable soundproof windows or other openable buildings to prevent outdoor noise from directly entering the room through the gap at the bottom of the openable soundproof doors, openable soundproof windows or other openable buildings. By using the sliding seat 100, the lifting mechanism 200 and the sealing mechanism 300, when the sliding assembly 210 slides away from the accommodating cavity 120, the sliding seat 100 and the sealing mechanism 300 are supported by the lifting mechanism 200 and leave the floor, the sill or the wall, thereby avoiding the sliding seat 100 and the sealing mechanism 300. The mechanism 300 moves downward due to the action of gravity and contacts the floor, counter-sill or wall, which increases the friction between the sealing mechanism 300 and the floor, counter-sill or wall during the movement, increases the problem of movement resistance, and thus improves the convenience of movement; when the sliding assembly 210 slides toward the accommodating cavity 120, the sliding seat 100 and the sealing mechanism 300 are not supported by the lifting mechanism 200, so that the sliding seat 100 and the sealing mechanism 300 move downward due to the action of gravity and fit tightly with the floor, counter-sill or wall, effectively preventing outdoor noise from directly entering the room through the gap at the bottom of the openable soundproof door, openable soundproof window or other openable building, thereby improving the sound insulation effect.

[0045] It can also be understood that if the sliding seat 100, the lifting mechanism 200 and the sealing mechanism 300 are used in conjunction with each other to achieve the sealing of the bottom of the openable soundproof door, the openable soundproof window or other openable building, and the gap at the bottom of the openable soundproof door, the openable soundproof window or other openable building is sealed, then another issue that needs to be considered is how to ensure that the sealing structure is tightly fitted with the floor, threshold or wall when the openable soundproof door, the openable soundproof window or other openable building is closed. If the sealing strip or other sealing structure is directly pulled up by the spring, and then the sealing strip or other sealing structure is pushed up by the upper connecting block or other pushing structure, The sealing structure is controlled up and down to achieve the up and down movement of the sealing strip or other sealing structure. There is a problem that the control accuracy of the connecting block or other pushing structure to control the up and down movement distance of the sealing strip or other sealing structure is relatively high. If the control accuracy is poor, the sealing structure will not fit closely with the floor, door sill or wall, which will lead to poor sound insulation effect of the openable soundproof door, openable soundproof window or other openable building. Or it may cause the sealing strip or other sealing structure to be in close contact with the floor, sill or wall when the connecting block has not fully entered the door leaf, so that the door leaf cannot be closed smoothly. Therefore, in the sound insulation structure 10 of the present invention, the sliding assembly 210 passes through the sliding base 100, and both ends of the sliding assembly 210 are used to connect to the mounting base 30. That is, the telescopic assembly 220 and the lifting assembly 230 directly support the sliding base 100 and the sealing mechanism 300 as a whole, avoiding the need for additional structures to support the sealing mechanism 300. In addition, the sliding base 100 and the sealing mechanism 300 are not supported by the sliding assembly 210 and the lifting assembly 230 when the openable sound insulation door, openable sound insulation window, or other openable building is closed. The sliding base 100 and the sealing mechanism 300 move downward due to gravity and are closely attached to the floor, threshold, or wall. That is, the lifting assembly 230 and the sliding assembly 210 do not need to accurately control the descent of the sliding base 100 and the sealing mechanism 300, and the sealing mechanism 300 is closely attached to the floor or wall. Furthermore, the lifting assembly 230 and the sliding assembly 210 directly support the sliding seat 100 and the sealing mechanism 300 as a whole, thereby improving the support stability of the sliding assembly 210 and the lifting assembly 230 on the sliding seat 100 and the sealing mechanism 300, and making it difficult for the sliding seat 100 to fall off the sliding assembly 210, thereby improving the structural stability of the openable soundproof door, openable soundproof window or other openable building.

[0046] It should be noted that the floor, sill, or wall serves as the abutment 40 against the sound insulation structure 10 when the door 20 is closed against the door frame 20a. Both "door 20 closed against door frame 20a" and "door 20 closed" indicate that the periphery of the door 20 and the periphery of the door frame 20a are completely aligned; whereas "door 20 open against door frame 20a" and "door 20 open" both indicate that the periphery of the door 20 and the periphery of the door frame 20a are partially aligned.

[0047] In one embodiment, the sliding assembly 210 is a connecting rod, which ensures the structural strength of the sliding assembly 210 .

[0048] In one embodiment, the sealing mechanism 300 is a sealing ring. Specifically, the sealing mechanism 300 is a rubber sealing ring, which ensures the sealing effect of the sealing mechanism 300 .

[0049] Please also refer to Figure 3 、 Figure 6 and Figure 7In one embodiment, the lifting assembly 230 includes a first adjustment member 231 and a second adjustment member 232. The first adjustment member 231 is disposed on the sliding assembly 210, and the second adjustment member 232 is connected to at least one of the sliding seat 100 and the mounting seat 30. The first adjustment member 231 and the second adjustment member 232 are disposed correspondingly. When the telescopic assembly 220 is compressed, the first adjustment member 231 slides away from the second adjustment member 232; when the telescopic assembly 220 is released, the first adjustment member 231 slides toward the second adjustment member 232. It can be understood that the first adjustment member 231 is provided on the sliding assembly 210, and the first adjustment member 231 is provided corresponding to the second adjustment member 232 provided on at least one of the sliding seat 100 and the mounting seat 30, wherein, when the telescopic assembly 220 is compressed, the first adjustment member 231 slides away from the second adjustment member 232, and the first adjustment member 231 has no supporting effect on the sliding seat 100 and the sealing mechanism 300, so that the sliding seat 100 and the sealing mechanism 300 move downward due to gravity, and the downward movement of the sliding seat 100 and the sealing mechanism 300 occurs due to gravity, which is not affected by the control accuracy of the sliding assembly 210, thereby ensuring the sealing mechanism 300 has a sealing effect with the floor, sill or wall; when the telescopic component 220 is loosened, the first adjusting member 231 slides toward the second adjusting member 232, and the first adjusting member 231 and the second adjusting member 232 produce mechanical interference, so that the sliding component 210 drives the sliding seat 100 and the sealing mechanism 300 to move upward, thereby realizing the upward movement of the sliding seat 100 and the sealing mechanism 300, avoiding the sliding seat 100 and the sealing mechanism 300 from moving downward due to the action of gravity and contacting the floor, sill or wall, so that the friction between the sealing mechanism 300 and the floor, sill or wall during the activity increases, thereby increasing the activity resistance and improving the convenience of the activity.

[0050] Please also refer to Figure 5 and Figure 6In this embodiment, the second adjustment member 232 is disposed on the sliding seat 100, and both the first adjustment member 231 and the second adjustment member 232 are wedge-shaped blocks. The first adjustment member 231 is provided with a first wedge surface 2311, and the second adjustment member 232 is provided with a second wedge surface 2321. The first wedge surface 2311 and the second wedge surface 2321 are slidably connected. When the first adjustment member 231 slides away from the second adjustment member 232, the first wedge surface 2311 and the second wedge surface 2321 are aligned. When the first adjustment member 231 slides toward the second adjustment member 232, the first wedge surface 2311 and the second wedge surface 2321 are offset. It should be noted that when the first wedge surface 2311 and the second wedge surface 2321 are aligned, the sliding assembly 210 or the first adjustment member 231 does not hinder the downward movement of the sliding seat 100 and the sealing mechanism 300. It can be understood that when the first wedge surface 2311 of the first adjusting member 231 and the second wedge surface 2321 of the second adjusting member 232 are arranged in an interlaced manner, the first adjusting member 231 and the second adjusting member 232 are subject to mutual mechanical interference, so that the sliding assembly 210 supports the sliding seat 100 and the sealing mechanism 300, thereby realizing the upward movement of the lifting sliding seat 100 and the sealing mechanism 300; when the first wedge surface 2311 of the first adjusting member 231 and the second wedge surface 2321 of the second adjusting member 232 are arranged relative to each other, the first adjusting member 231 and the second adjusting member 232 lose mutual mechanical interference, so that the sliding assembly 210 loses its supporting effect on the lifting sliding seat 100 and the sealing mechanism 300, thereby realizing the downward movement of the sliding seat 100 and the sealing mechanism 300 due to gravity. The provision of the first wedge surface 2311 and the second wedge surface 2321 improves the sliding smoothness of the sliding component 210 when it slides away from the accommodating cavity 120. That is, when using the telescopic component 220 with smaller elastic force, the sliding component 210 can slide more smoothly relative to the sliding seat 100, reducing the elastic strength requirement for the telescopic component 220.

[0051] Please also refer to Figure 7In another embodiment, the second adjustment member 232 is disposed on the sliding seat 100, and both the first adjustment member 231 and the second adjustment member 232 are magnetic members. The north pole of the first adjustment member 231 is disposed correspondingly to the north pole of the second adjustment member 232, and / or the south pole of the first adjustment member 231 is disposed correspondingly to the south pole of the second adjustment member 232. That is, the corresponding portions of the first adjustment member 231 and the second adjustment member 232 have the same magnetic properties, thereby repelling each other. It can be understood that when the first adjusting member 231 and the second adjusting member 232 are arranged relative to each other, the first adjusting member 231 and the second adjusting member 232 are subjected to mutual repulsive force, so that the sliding assembly 210 supports the sliding seat 100 and the sealing mechanism 300, thereby realizing the upward movement of the sliding seat 100 and the sealing mechanism 300; when the first adjusting member 231 and the second adjusting member 232 are arranged in an alternating manner, the mutual repulsive force exerted on the first adjusting member 231 and the second adjusting member 232 disappears, so that the sliding assembly 210 loses its supporting effect on the sliding seat 100 and the sealing mechanism 300, thereby realizing the downward movement of the sliding seat 100 and the sealing mechanism 300 due to gravity.

[0052] In one embodiment, the second adjusting member 232 is arranged on the sliding seat 100, and the number of the first adjusting member 231 and the second adjusting member 232 is multiple, and the first adjusting member 231 and the second adjusting member 232 are arranged in a one-to-one correspondence, thereby improving the supporting stability of the first adjusting member 231 on the sliding seat 100 and the sealing mechanism 300.

[0053] It is understood that in another embodiment, the second adjusting member 232 is not limited to being provided on the sliding seat 100, but may also be provided on the mounting seat 30. Figure 2 、 Figure 3 and Figure 4In one embodiment, the second adjustment member 232 is disposed on the mounting seat 30, and both the first adjustment member 231 and the second adjustment member 232 are wedge-shaped blocks. The first adjustment member 231 is provided with a first wedge surface 2311, and the second adjustment member 232 is provided with a second wedge surface 2321. The first wedge surface 2311 and the second wedge surface 2321 are slidably connected. When the first adjustment member 231 slides away from the second adjustment member 232, the first wedge surface 2311 and the second wedge surface 2321 are aligned. When the first adjustment member 231 slides toward the second adjustment member 232, the first wedge surface 2311 and the second wedge surface 2321 are offset. It should be noted that when the first wedge surface 2311 and the second wedge surface 2321 are aligned, the sliding assembly 210 or the first adjustment member 231 does not hinder the downward movement of the sliding seat 100 and the sealing mechanism 300. It can be understood that when the first wedge surface 2311 of the first adjusting member 231 and the second wedge surface 2321 of the second adjusting member 232 are arranged in an interlaced manner, the first adjusting member 231 and the second adjusting member 232 are subject to mutual mechanical interference, so that the sliding assembly 210 supports the sliding seat 100 and the sealing mechanism 300, thereby realizing the upward movement of the sliding seat 100 and the sealing mechanism 300; when the first wedge surface 2311 of the first adjusting member 231 and the second wedge surface 2321 of the second adjusting member 232 are arranged relative to each other, the first adjusting member 231 and the second adjusting member 232 lose mutual mechanical interference, so that the sliding assembly 210 loses its supporting effect on the sliding seat 100 and the sealing mechanism 300, thereby realizing the downward movement of the sliding seat 100 and the sealing mechanism 300 due to gravity. The provision of the first wedge surface 2311 and the second wedge surface 2321 improves the sliding smoothness of the sliding component 210 when it slides away from the accommodating cavity 120. That is, when using the telescopic component 220 with smaller elastic force, the sliding component 210 can slide more smoothly relative to the sliding seat 100, reducing the elastic strength requirement for the telescopic component 220.

[0054] Please also refer to Figure 1 、 Figure 2 and Figure 5In one embodiment, the sound insulation structure 10 further includes a muffler 400, which is connected to the sliding base 100 and disposed on the same horizontal plane as the sliding base. It is understood that to ensure that the weight of the sliding base 100 and the sealing mechanism 300 is sufficient to enable the sealing mechanism 300 to be tightly connected to the floor, threshold, or wall, a heavy sliding base 100 and sealing mechanism 300 are required, which increases the material cost of the sound insulation structure 10. Furthermore, although the sliding base 100 and sealing mechanism 300 provide a sealing effect, preventing outdoor noise from being directly transmitted into the room through the gaps at the bottom of an openable soundproof door, openable soundproof window, or other openable building structure, the sound absorption effect of the sliding base 100 and sealing mechanism 300 is not good, and they cannot effectively absorb outdoor noise to achieve a good noise reduction effect. Therefore, in the present invention, the sliding seat 100 and the silencer 400 are connected and arranged on the same horizontal plane. The silencer 400 is used to increase the weight of the sliding seat 100 and the sealing mechanism 300, ensuring that the sliding seat 100 and the sealing mechanism 300 can be tightly abutted against the floor, threshold or wall due to the action of gravity, and the sound absorption performance of the silencer 400 is used to improve the noise absorption effect of the sound insulation structure 10.

[0055] Please also refer to Figure 1 In one embodiment, a plurality of silencer holes 410 are provided on the silencer 400, and the silencer holes 410 are used to communicate with the outside, and the silencer holes 410 are used to communicate with the chute 31, so that the silencer 400 effectively improves the sound absorption and noise reduction effect of the sound insulation structure 10 through microporous sound reduction.

[0056] In one embodiment, a silencer cavity 420 is further provided on the silencer 400, and the silencer cavity 420 is connected to the silencer hole 410, so that the silencer 400 can effectively improve the sound absorption and noise reduction effect of the sound insulation structure 10 by means of resistive sound reduction.

[0057] Please also refer to Figure 1 、 Figure 6 and Figure 8The present application also provides a soundproof door 10a, comprising a door body 20, a mounting seat 30, and the soundproof structure 10 described in any of the above embodiments. The door body 20 is connected to the mounting seat 30, the sliding seat 100 is located on the mounting seat 30 and is slidably connected to the mounting seat 30, and the sliding hole 110 is connected to the sliding groove 31. A sliding assembly 210 is slidably connected to the mounting seat 30, and a lifting assembly 230 is connected to at least one of the sliding seat 100 and the mounting seat 30. When the sliding assembly 210 slides relative to the sliding seat 100, the lifting assembly 230 raises and lowers the relative connection position between the sliding seat 100 and the mounting seat 30, causing the sliding seat 100 to slide out of or into the sliding groove 31. The sealing mechanism 300 is located on the side of the sliding seat 100 away from the door body 20. The door body 20 defines a first through-hole 24 that is connected to the sliding groove 31, and the first through-hole 24 corresponds to the sliding hole 110. The sliding assembly 210 is also inserted into the first through-hole 24 and is slidably connected to the door body 20. Specifically, the sound insulation structure 10 includes a sliding seat 100, a lifting mechanism 200, and a sealing mechanism 300. The sliding seat 100 is located in the sliding groove 31 and is slidably connected to the mounting seat 30. The sliding seat 100 defines a sliding hole 110 and an accommodating cavity 120 that communicate with each other. The sliding hole 110 communicates with the sliding groove 31. The lifting mechanism 200 includes a sliding assembly 210, a telescopic assembly 220, and a lifting assembly 230. The sliding assembly 210 is disposed within the sliding hole 110 and is slidably connected to the sliding seat 100. The sliding assembly 210 is also slidably connected to the mounting seat 30. The telescopic assembly 220 is located within the accommodating cavity 120 and is sleeved on the sliding assembly 210. The ends of the telescopic assembly 220 abut against the mounting seat 30 and the sliding assembly 210, respectively. The lifting assembly 230 is connected to the sliding assembly 210 and is also connected to at least one of the sliding seat 100 and the mounting seat 30. The lifting assembly 230 is used to adjust the relative connection position between the sliding seat 100 and the mounting seat 30 when the sliding assembly 210 slides relative to the sliding seat 100. The sealing mechanism 300 is connected to the sliding seat 100 and is located on the side of the sliding seat 100 facing the notch of the slide groove 31. Among them, when the telescopic component 220 is compressed, the sliding component 210 slides toward the accommodating chamber 120, and the sliding seat 100 is driven by gravity to drive the sealing mechanism 300 to move downward; when the telescopic component 220 is released, the sliding component 210 slides away from the accommodating chamber 120, and the sliding seat 100 is supported by the telescopic component 220 to drive the sealing mechanism 300 to move upward.

[0058] In the above-mentioned soundproof door 10a, the bottom of the door body 20 of the soundproof door 10a is sealed by the sound insulation structure, wherein, when the door body 20 is closed, the telescopic assembly 220 is pressed, the sliding assembly 210 slides toward the accommodating chamber 120, and the sliding seat 100 is driven by gravity to drive the sealing mechanism 300 to move downward. At this time, the sliding assembly 210 is still located in the first insertion hole 24 and is slidably connected to the door body 20; when the door body 20 is opened, the telescopic assembly 220 is released, the sliding assembly 210 slides away from the accommodating chamber 120, and the sliding seat 100 is supported by the lifting assembly 230 to drive the sealing mechanism 300 to move upward. At this time, the sliding assembly 210 is still located in the first insertion hole 24 and is slidably connected to the door body 20, that is, when the sliding assembly 210 slides away from the accommodating chamber 120, the sliding seat 100 is 0 and the sealing mechanism 300 are supported by the lifting mechanism 200 and leave the floor, counter-sill or door sill, avoiding the sliding seat 100 and the sealing mechanism 300 from moving downward due to the action of gravity and contacting the floor, counter-sill or door sill, so that the friction between the sealing mechanism 300 and the floor, counter-sill or door sill increases during the activity, resulting in increased activity resistance, thereby improving the activity convenience of the door body 20; when the sliding assembly 210 slides toward the accommodating cavity 120, the sliding seat 100 and the sealing mechanism 300 are not supported by the lifting mechanism 20, so that the sliding seat 100 and the sealing mechanism 300 move downward due to the action of gravity and fit tightly with the floor, counter-sill or door sill, effectively avoiding outdoor noise directly entering the room from the gap at the bottom, thereby improving the sound insulation effect of the soundproof door 10a. The sound insulation structure 10 is disposed on the mounting base 30, and the mounting base 30 is disposed on the door body 20. That is, the sound insulation structure 10 is disposed on the door body 20, and the sliding assembly 210 passes through the sliding base 100, and both ends of the sliding assembly 210 are connected to the mounting base 30. In this way, the telescopic assembly 220 and the lifting assembly 230 directly support the sliding base 100 and the sealing mechanism 300 as a whole, avoiding the need for additional structures to support the sealing mechanism 300. In addition, when the sound insulation door 10a is closed, the sliding base 100 and the sealing mechanism 300 are not supported by the sliding assembly 210 and the lifting assembly 230. This allows the sliding base 100 and the sealing mechanism 300 to move downward due to gravity and to fit tightly with the floor, door sill, or counter-sill. In other words, the lifting assembly 230 and the sliding assembly 210 do not need to accurately control the descent of the sliding base 100 and the sealing mechanism 300, thereby achieving tight fit between the sealing mechanism 300 and the floor or counter-sill. Furthermore, the lifting assembly 230 and the sliding assembly 210 directly support the sliding seat 100 and the sealing mechanism 300 as a whole, thereby improving the supporting stability of the sliding assembly 210 and the lifting assembly 230 on the sliding seat 100 and the sealing mechanism 300, and making it difficult for the sliding seat 100 to fall off the sliding assembly 210, thereby improving the structural stability of the sound insulation door 10a.

[0059] Please also refer to Figure 3 In one embodiment, the door body 20 includes a shell 211 and a fireproof and soundproofing filler 212. The shell 211 is connected to the mounting base 30 and is covered by the fireproof and soundproofing filler 212. It is understood that fire is a huge safety hazard and often occurs in ordinary homes, factories, or office buildings. Once a fire occurs, it spreads very quickly, seriously endangering personal safety and property safety. Therefore, in order to reduce the harm of fire and slow the spread of fire and further increase rescue time, in the present invention, the fireproof and soundproofing filler 212 is utilized to achieve the fireproof performance of the door body 20 of the soundproof door 10a while ensuring the sound insulation effect of the door body 20 of the soundproof door 10a.

[0060] In one embodiment, the shell 211 and the mounting base 30 are an integrally formed structure, which reduces the processing steps of the sound insulation door 10a and reduces the processing cost, making the structure of the door body 20 and the mounting base 30 more compact, further improving the structural compactness of the sound insulation door 10a, and making the connection between the door body 20 and the mounting base 30 more firm and stable, further improving the structural stability of the sound insulation door 10a.

[0061] Please also refer to Figure 3 and Figure 6 In one embodiment, the fireproof and sound-absorbing filling body 212 includes a fireproof and sound-insulating layer 2121 and a sound-absorbing cotton body 2122. The fireproof and sound-insulating layer 2121 is coated on the sound-absorbing cotton body 2122, and the housing 211 is coated on the fireproof and sound-insulating layer 2121. It can be understood that the sound-absorbing cotton body 2122 has noise-absorbing properties, so the fireproof and sound-insulating layer 2121 coated on the sound-absorbing cotton body 2122 reduces the impact of fire on the sound-absorbing cotton body 2122, and makes the soundproof door 10a fireproof, ensuring the safety and sound insulation and noise reduction performance of the soundproof door 10a.

[0062] In one embodiment, the fireproof and sound-insulating layer 2121 is a calcium silicate layer, so that the fireproof and sound-insulating layer 2121 has better fireproof performance, thereby improving the safety performance of the soundproof door 10a.

[0063] In one embodiment, the thickness of the fireproof and sound-insulating layer 2121 is 8 mm to 12 mm, so that the fireproof and sound-insulating layer 2121 has good fireproof performance, thereby improving the safety performance of the soundproof door 10a.

[0064] In one embodiment, the sound absorbing cotton body 2122 is rock wool. In this embodiment, the density of rock wool is 70kg / cm 3 ~90kg / cm 3 , which makes the sound-absorbing cotton body 2122 have a better sound-absorbing effect, thereby improving the sound-absorbing and noise-reducing performance of the soundproof door 10a.

[0065] Please also refer to Figure 9 and Figure 10 The present application also provides a sealed door device 10b, comprising a door frame 20a and any of the above-described soundproof doors 10a. The door body 20 is movably connected to the door frame 20a, and a sliding assembly 210 is configured to abut against the door frame 20a when the door body 20 is closed against the door frame 20a. The soundproof door 10a comprises a door body 20, a mounting base 30, and a soundproof structure 10 according to any of the above-described embodiments. The door body 20 is connected to the mounting base 30, a sliding base 100 is positioned on the mounting base 30 and slidably connected thereto, a sliding assembly 210 is slidably connected to the mounting base 30, and a lifting assembly 230 is connected to at least one of the sliding base 100 and the mounting base 30. The lifting assembly 230 is configured to adjust the relative connection position between the sliding base 100 and the mounting base 30 when the sliding assembly 210 slides relative to the sliding base 100. The sealing mechanism 300 is located on the side of the sliding base 100 away from the door body 20.

[0066] Please also refer to Figure 1 、 Figure 3 and Figure 6 Specifically, the sound insulation structure 10 includes a sliding seat 100, a lifting mechanism 200, and a sealing mechanism 300. The sliding seat 100 is located in a sliding groove 31 and is slidably connected to the mounting seat 30. The sliding seat 100 defines a sliding hole 110 and a receiving cavity 120 that communicate with each other. The sliding hole 110 is connected to the sliding groove 31. The lifting mechanism 200 includes a sliding assembly 210, a telescopic assembly 220, and a lifting assembly 230. The sliding assembly 210 is disposed within the sliding hole 110 and is slidably connected to the sliding seat 100. The sliding assembly 210 is also slidably connected to the mounting seat 30. The telescopic assembly 220 is located within the accommodating cavity 120 and is sleeved on the sliding assembly 210. The ends of the telescopic assembly 220 abut against the mounting seat 30 and the sliding assembly 210, respectively. The lifting assembly 230 is connected to the sliding assembly 210 and is also connected to at least one of the sliding seat 100 and the mounting seat 30. The lifting assembly 230 is used to adjust the relative connection position between the sliding seat 100 and the mounting seat 30 when the sliding assembly 210 slides relative to the sliding seat 100. The sealing mechanism 300 is connected to the sliding seat 100 and is located on the side of the sliding seat 100 facing the notch of the slide groove 31. Among them, when the telescopic component 220 is compressed, the sliding component 210 slides toward the accommodating chamber 120, and the sliding seat 100 is driven by gravity to drive the sealing mechanism 300 to move downward; when the telescopic component 220 is released, the sliding component 210 slides away from the accommodating chamber 120, and the sliding seat 100 is supported by the telescopic component 220 to drive the sealing mechanism 300 to move upward.

[0067] In the above-mentioned sealing door device 10b, when the door frame 20a squeezes the sliding assembly 210 into the door body 20, the sliding assembly 210 slides toward the placement cavity, and the sliding seat 100 and the sealing mechanism 300 move downward due to gravity; when the door frame 20a releases the sliding assembly 210, the sliding assembly 210 slides away from the placement cavity, and the sliding assembly 210 drives the lifting assembly 230 to move upward, thereby supporting the sliding seat 100 and the sealing mechanism 300. That is, when the sealing door device 10b is open, the sliding seat 100 and the sealing mechanism 300 are supported by the sliding assembly 210 and the lifting assembly 230 and leave the floor, the sill or the door threshold, thereby avoiding the sliding seat 100 and the sealing mechanism 300 from being lifted up due to gravity. The door body 20 moves downward and contacts the floor, sill or door threshold, so that the friction between the door body 20 and the floor, sill or door threshold increases during the movement relative to the door frame 20a, thereby improving the movement resistance of the door body 20 and improving the movement convenience of the door body 20 relative to the door frame 20a; in the closed state of the sealing door device 10b, the sliding part and the sealing mechanism 300 are not supported by the sliding assembly 210 and the lifting assembly 230, so that the sliding seat 100 and the sealing mechanism 300 move downward due to gravity and fit tightly with the floor, door threshold or sill, effectively avoiding outdoor noise from directly entering the room from the gap at the bottom of the door body 20, thereby improving the sound insulation effect of the sealing door device 10b. The sound insulation structure 10 is disposed on the mounting base 30, and the mounting base 30 is disposed on the door body 20. That is, the sound insulation structure 10 is disposed on the door body 20, and the sliding assembly 210 passes through the sliding base 100, and both ends of the sliding assembly 210 are connected to the mounting base 30. In this way, the telescopic assembly 220 and the lifting assembly 230 directly support the sliding base 100 and the sealing mechanism 300 as a whole, avoiding the need for additional structures to support the sealing mechanism 300. In addition, when the sound insulation door 10a is closed, the sliding base 100 and the sealing mechanism 300 are not supported by the sliding assembly 210 and the lifting assembly 230. This allows the sliding base 100 and the sealing mechanism 300 to move downward due to gravity and to fit tightly with the floor, door sill, or counter-sill. In other words, the lifting assembly 230 and the sliding assembly 210 do not need to accurately control the descent of the sliding base 100 and the sealing mechanism 300, thereby achieving tight fit between the sealing mechanism 300 and the floor or counter-sill. Moreover, the lifting assembly 230 and the sliding assembly 210 directly support the sliding seat 100 and the sealing mechanism 300 as a whole, thereby improving the supporting stability of the sliding assembly 210 and the lifting assembly 230 on the sliding seat 100 and the sealing mechanism 300, and making it difficult for the sliding seat 100 to fall off the sliding assembly 210, thereby improving the structural stability of the sealing door device 10b.

[0068] Please also refer to Figure 10 and Figure 11In one embodiment, the door frame 20a includes a door frame body 21a and a gap sealing assembly 22a. The door frame body 21a is movably connected to the door body 20. The gap sealing assembly 22a is mounted on the periphery of the door frame body 21a. The sliding assembly 210 is configured to abut against either the gap sealing assembly 22a or the door frame body 21a when the door body 20 is closed against the door frame 20a. It will be appreciated that the use of the gap sealing assembly 22a to seal the gap between the door body 20 and the door frame 20a further prevents outdoor noise from being directly transmitted into the room through the gap between the door body 20 and the door frame 20a of the sealed door device 10b, thereby improving the sound insulation effect of the sealed door device 10b.

[0069] Please also refer to Figure 11 and Figure 12 In one embodiment, the gap sealing assembly 22a includes a fixing member 223a and an elastic sealing member 224a, the fixing member 223a is connected to the door frame body 21a, and the elastic sealing member 224a is installed on a side wall of the fixing member 223a close to the door body 20. The elastic sealing member 224a is arranged corresponding to the periphery of the door frame body 21a, and abuts against the periphery of the door body 20 when the periphery of the door body 20 is arranged corresponding to the periphery of the door frame body 21a. It can be understood that the fixing member 223a fixes the elastic seal 224a to prevent the elastic seal 224a from moving and reducing the sealing effect. The elastic seal 224a is fixed on the door frame body 21a. When the sealing door device 10b is closed, the periphery of the door body 20 abuts against the elastic seal 224a. At this time, the elastic seal 224a undergoes elastic deformation and fits tightly with the door body 20, further preventing outdoor noise from directly transmitting into the room through the gap at the bottom of the door body 20, thereby improving the sound insulation effect of the sealing door device 10b.

[0070] It should also be noted that in one embodiment, elastic sealing members 224a are provided around the periphery of the door frame 20a, which better prevents outdoor noise from being directly transmitted into the room through the gap between the door body 20 and the door frame 20a of the sealed door device 10b, thereby improving the sound insulation effect of the sealed door device 10b.

[0071] Please also refer to Figure 13In one embodiment, the gap sealing component 22a includes a first sealing component 221a and / or a second sealing component 222a, and the first sealing component 221a and the second sealing component 222a are both installed on the door frame body 21a, and the first sealing component 221a and the second sealing component 222a are both arranged corresponding to the periphery of the door frame body 21a. When the periphery of the door body 20 is arranged corresponding to the periphery of the door frame body 21a, the first sealing component 221a is clamped between the door body 20 and the door frame body 21a, and when the periphery of the door body 20 is arranged corresponding to the periphery of the door frame body 21a, the second sealing component 222a abuts against the periphery of the door body 20, thereby better preventing outdoor noise from directly entering the room from the gap between the door body 20 and the door frame 20a of the sealing door device 10b, thereby improving the sound insulation effect of the sealing door device 10b.

[0072] In one embodiment, the first sealing component 221a is an EPDM rubber sealing strip, which ensures the sealing effect of the gap between the door frame 20a and the door body 20, thereby ensuring the sound insulation effect of the sealed door device 10b. In this embodiment, the first sealing component 221a is provided along the periphery of the door frame 20a, which better prevents outdoor noise from being directly transmitted into the room through the gap between the door body 20 and the door frame 20a of the sealed door device 10b, thereby improving the sound insulation effect of the sealed door device 10b.

[0073] Please also refer to Figure 13In one embodiment, the second sealing component 222a includes a mounting member 2221 and an abutting seal 2222. The mounting member 2221 is connected to the door frame body 21a. The abutting seal 2222 is installed on a side wall of the mounting member 2221 close to the door body 20. The abutting seal 2222 is arranged corresponding to the periphery of the door frame body 21a, and abuts against the periphery of the door body 20 when the periphery of the door body 20 is arranged corresponding to the periphery of the door frame body 21a. It is understood that the mounting member 2221 secures the abutting seal 2222 to prevent it from moving and reducing the sealing effect. The abutting seal 2222 is mounted on the door frame body 21a. When the sealed door device 10b is closed, the periphery of the door body 20 abuts the abutting seal 2222. At this time, the abutting seal 2222 undergoes elastic deformation and fits tightly with the door body 20, further preventing outdoor noise from being directly transmitted into the room through the gap between the door body 20 and the door frame 20a of the sealed door device 10b, thereby improving the sound insulation effect of the sealed door device 10b. It should also be noted that in one embodiment, the periphery of the door frame 20a is provided with abutting seals 2222, further preventing outdoor noise from being directly transmitted into the room through the gap between the door body 20 and the door frame 20a of the sealed door device 10b, thereby further improving the sound insulation effect of the sealed door device 10b. In this embodiment, the abutting seal 2222 is a sealing strip, which ensures the sealing effect of the gap between the door frame 20a and the door body 20, and further ensures the sound insulation effect of the sealed door device 10b.

[0074] Please also refer to Figure 8 and Figure 11 In one embodiment, the door body 20 includes a first door leaf 21 and a second door leaf 22. The first door leaf 21 and the second door leaf 22 are arranged side by side. The first door leaf 21 and the second door leaf 22 are relatively arranged on the door frame 20a and are both movably connected to the door frame 20a. It can be understood that if the user needs to set a larger sealing door device 10b, if a single-opening sealing door device is formed by connecting a single door leaf to the door frame 20a, the connection between the door leaf and the door frame 20a will be subjected to greater force, causing the door body 20 to jam and easily damage the door frame 20a. Therefore, the sealing door device 10b is formed into a double-opening sealing door device, which reduces the force on the connection between the door body 20 and the door frame 20a and increases the smoothness of the movement of the door body 20, thereby improving the service life and convenience of the sealing door device 10b.

[0075] Please also refer to Figure 8In one embodiment, the door body 20 further includes a door leaf sealing assembly 23, which is disposed on the first door leaf 21 and / or the second door leaf 22. The door leaf sealing assembly 23 is connected to the first door leaf 21 and the second door leaf 22 when the first door leaf 21 and the second door leaf 22 are both disposed correspondingly to the periphery of the door frame body 21a. It is understood that if the sealing door device 10b is a double-opening sealing door device 10b, there is still a gap between the first door leaf 21 and the second door leaf 22. The door leaf sealing assembly 23 is used to seal the gap between the first door leaf 21 and the second door leaf 22, thereby preventing outdoor noise from being directly transmitted into the room through the gap between the first door leaf 21 and the second door leaf 22 of the sealing door device 10b, thereby improving the sound insulation effect of the sealing door device 10b.

[0076] Please also refer to Figure 8 、 Figure 9 and Figure 10 In one embodiment, the sealing door device 10b also includes a door lock 30a, which includes a door lock body 31a and a snap body 32a. The door lock body 31a is arranged on the door body 20, and the snap body 32a is arranged on the door body 20 or the door frame 20a. When the periphery of the door body 20 and the periphery of the door frame 20a are arranged correspondingly, the door lock body 31a is snapped onto the snap body 32a, so that the sealing door device 10b has the function of a lock, thereby enhancing the user's convenience.

[0077] Please also refer to Figure 9 In one embodiment, the sealing door device 10b further includes a bolt 40a, which is movably connected to the door body 20, and the bolt 40a is used to be clamped on the door frame 20a when the periphery of the door body 20 and the periphery of the door frame 20a are correspondingly arranged, thereby improving the closing reliability of the door body 20 and the door frame 20a.

[0078] Please also refer to Figure 9 and Figure 11 In one embodiment, the door body 20 and the door frame 20a are movably connected through hinges or hinges, which improves the connection stability between the door body 20 and the door frame 20a.

[0079] Compared with the prior art, the sound insulation structure 10 of the present invention has at least the following advantages:

[0080] 1. In the sound insulation structure 10 of the present invention, the sliding seat 100, the lifting mechanism 200 and the sealing mechanism 300 cooperate to achieve the sealing of the bottom of the openable sound insulation door 10a, the openable sound insulation window or other openable building. When the telescopic assembly 220 is compressed, the sliding assembly 210 slides toward the accommodating chamber 120, and the sliding seat 100 is driven by gravity to move the sealing mechanism 300 downward; when the telescopic assembly 220 is released, the sliding assembly 210 slides away from the accommodating chamber 120, and the sliding seat 100 is supported by the lifting assembly 230 to drive the sealing mechanism 300 upward. That is, when the sliding assembly 210 slides away from the accommodating chamber 120, the sliding seat 100 and the sealing mechanism 300 are lifted and lowered. The support of the lowering mechanism 200 leaves the floor, sill or wall, preventing the sliding seat 100 and the sealing mechanism 300 from moving downward due to gravity and contacting the floor, sill or wall. This increases the friction between the sealing mechanism 300 and the floor, sill or wall during movement, resulting in increased movement resistance, thereby improving the convenience of movement. When the sliding assembly 210 slides toward the accommodating cavity 120, the sliding seat 100 and the sealing mechanism 300 are not supported by the lifting mechanism 200. Therefore, the sliding seat 100 and the sealing mechanism 300 move downward due to gravity and fit tightly with the floor, sill or wall, effectively preventing outdoor noise from directly entering the room through the gap at the bottom, thereby improving the sound insulation effect.

[0081] 2. In the sound insulation structure 10 of the present invention, the sliding assembly 210 is inserted into the sliding seat 100, and both ends of the sliding assembly 210 are slidably connected to the sliding seat 100. That is, the sliding assembly 210 and the lifting assembly 230 directly support the sliding seat 100 and the sealing mechanism 300 as a whole, thereby improving the supporting stability of the sliding assembly 210 and the lifting assembly 230 on the sliding seat 100 and the sealing mechanism 300, and making it difficult for the sliding seat 100 to fall off the sliding assembly 210, thereby improving the structural stability of the sound insulation structure 10.

[0082] The above embodiments merely illustrate several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
