Description

Technical Field

[0001] This utility model relates to the field of noise reduction technology, and in particular to a lifting sealing structure and a soundproof door. Background Technology

[0002] Soundproof doors are special doors whose core function is to block the propagation of sound waves. They are crucial components in noise reduction projects and are widely used in places such as studios, dance halls, recording studios, conference rooms, and hospitals. For example, the invention patent application with application number CN202010201895.0 uses the cooperation of a first galvanized steel plate layer, a second galvanized steel plate layer, a low-frequency absorption layer, a mid-to-high-frequency absorption layer, and a sound-damping felt layer to improve the sound insulation effect. However, this does not involve adjusting the door body, which actually makes the door increasingly thick and heavy. In addition, regarding the position between the door and the floor, in order to ensure the sound insulation effect of the door, the door needs to fit tightly against the floor when closed. However, the heavy door will make it inconvenient to open and close. For example, application number CN202011334473. Patent application No. 7 describes a method that uses a sliding seat, a lifting mechanism, and a sealing mechanism to seal the bottom of openable soundproof doors, windows, or other openable structures. It also reduces friction between the door and the floor during opening and closing, effectively improving sound insulation while allowing for convenient opening and closing. However, the compression and telescopic components used are springs, meaning the sliding component needs to spring back to lift the sliding seat and sealing mechanism together. Springs are prone to permanent deformation and have limited return force. Under the weight of the sliding seat and sealing mechanism, their lifting capacity is poor, making it difficult to lift the sliding seat and sealing mechanism stably over extended periods, thus affecting the smoothness of opening and closing the soundproof door. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a lifting and sealing structure and a soundproof door that ensures the soundproofing effect while making the lifting and lowering of the soundproof door more stable, thereby ensuring the smooth opening and closing of the soundproof door.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A lifting and sealing structure includes a sealing seat for placement between a door and a floor. The sealing seat is slidably connected to the door in a direction away from or towards the floor. The sealing seat has a telescopic through-hole, the extension direction of which intersects the sliding direction of the sealing seat. The lifting and sealing structure further includes a sliding member, a lifting member, a rotating member, and a push-pull member. The sliding member is disposed at the telescopic through-hole, and both ends of the sliding member are slidably connected to the door. The lifting member is connected to the sliding member and also to the wall of the telescopic through-hole. The sliding direction of the sliding member is parallel to the extension direction of the telescopic through-hole. The lifting member is configured to push the sealing seat to move in a direction closer to or away from the floor when the sliding member slides on the door.

[0006] The rotating component is rotatably connected to the door. The rotation axis of the rotating component intersects the extension direction of the telescopic through hole. The rotating component is disposed at the end of the sliding component and exposed to the door. The rotating component is provided with a push-pull slide rail, which is arranged around the rotation axis of the rotating component. The two ends of the push-pull slide rail are at different distances from the rotation axis of the rotating component. The push-pull component is connected to the sliding component and slidably connected to the push-pull slide rail.

[0007] In one embodiment, the door is rotatably connected to the door frame, and the door is movably covered by the door frame;

[0008] The door frame is provided with a meshing track, the extension direction of the meshing track intersects the rotation axis of the door, and the extension direction of the meshing track is parallel to the thickness direction of the door when the door cover is installed on the door frame;

[0009] The rotating component is provided with a meshing component, which is arranged around the rotation axis of the rotating component. The meshing component protrudes from the door and is detachably meshed with the meshing track.

[0010] In one embodiment, the lifting member includes a first lifting part and a second lifting part, the first lifting part and the second lifting part being connected one-to-one to the hole wall of the telescopic through hole and the sliding member, and the first lifting part and the second lifting part being correspondingly arranged;

[0011] When the rotating member rotates, the first lifting part is configured to move toward or away from the second lifting part, so that the sliding member drives the sealing seat to move toward or away from the floor.

[0012] In one embodiment, the first lifting part is provided with a first wedge-shaped surface on the side near the second lifting part, and the second lifting part is provided with a second wedge-shaped surface on the side near the first lifting part, and the first wedge-shaped surface and the second wedge-shaped surface are slidably connected.

[0013] In one embodiment, the first lifting part and the second lifting part are magnets, and the magnetic pole of the first lifting part near the second lifting part is the same as the magnetic pole of the second lifting part near the first lifting part.

[0014] In one embodiment, the first lifting part and the sealing seat are integrally formed.

[0015] In one embodiment, the second lifting part and the sliding member are integrally formed.

[0016] In one embodiment, the sliding member has a rotation clearance groove at one end near the rotating member, the rotating member is partially housed in the rotation clearance groove and used to set the push-pull slide, and the push-pull member is set in the rotation clearance groove and slidably connected to the push-pull slide.

[0017] In one embodiment, the push-pull slide is a push-pull sliding hole, the depth direction of which is parallel to the rotation axis of the rotating member, and the two ends of the push-pull member protrude from the push-pull sliding hole and are respectively connected to the two groove walls of the rotating clearance groove.

[0018] A soundproof door includes a door, a door frame, and a lifting and sealing structure as described in any of the above embodiments. The door is rotatably connected to the door frame and movably covers the door frame. A sealing seat is disposed between the door and the floor. The sealing seat is slidably connected to the door in a direction away from or towards the floor. Both ends of a sliding member are slidably connected to the door. The lifting member is configured to push the sealing seat to move in a direction towards or away from the floor when the sliding member slides on the door.

[0019] The rotating component is rotatably connected to the door, and is disposed at the end of the sliding component and exposed to the door.

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

[0021] The lifting and sealing structure of this utility model allows the sealing seat to slide towards or away from the floor onto the door. The sealing seat has a telescopic through-hole, the extension direction of which intersects the sliding direction of the sealing seat. A sliding member is positioned at the telescopic through-hole, with both ends slidably connected to the door, thus supporting the sealing seat. A lifting member connects to the sliding member and is also connected to the wall of the telescopic through-hole. The sliding direction of the sliding member is parallel to the extension direction of the telescopic through-hole. The lifting member is configured to push the sealing seat towards or away from the floor when the sliding member slides on the door. This ensures that when the sliding member slides through the telescopic through-hole, it drives the lifting member to slide relative to the telescopic through-hole, and pushes the sealing seat towards or away from the floor. This effectively ensures the lifting and lowering of the soundproof door and guarantees the door's stability. The effective sound insulation of the soundproof door is further enhanced by a rotating component connected to the door. The rotation axis of the rotating component intersects with the extension direction of the telescopic through-hole. The rotating component is located at the end of the sliding component and exposed outside the door, allowing the rotating component to be adjusted from outside the door. The rotating component is equipped with a push-pull track, which is arranged around the rotation axis of the rotating component. The two ends of the push-pull track are at different distances from the rotation axis of the rotating component. The push-pull component is connected to the sliding component and slidably connected to the push-pull track. This causes the position of the push-pull component on the push-pull track to change when the rotating component rotates. Since the two ends of the push-pull track are at different distances from the rotation axis of the rotating component, the push-pull component drives the sliding component to move closer to and further away from the rotating component. Furthermore, without the use of a spring, the stable lifting and lowering of the sealing seat is effectively ensured, thus ensuring the smooth opening and closing of the soundproof door.

[0032] This application provides a lifting and sealing structure. The lifting and sealing structure includes a sealing seat, a sliding member, a lifting member, a rotating member, and a pushing and pulling member. The sealing seat is disposed between a door and the floor, and is slidably connected to the door in a direction away from or towards the floor. The sealing seat has a telescopic through-hole, the extension direction of which intersects the sliding direction of the sealing seat. The sliding member is disposed at the telescopic through-hole, and both ends of the sliding member are slidably connected to the door. The lifting member is connected to the sliding member and also to the wall of the telescopic through-hole. The sliding direction of the sliding member is parallel to the extension direction of the telescopic through-hole. The lifting member is configured to push the sealing seat to move in a direction closer to or away from the floor when the sliding member slides on the door. The rotating component is rotatably connected to the door. The rotation axis of the rotating component intersects the extension direction of the telescopic through hole. The rotating component is located at the end of the sliding component and exposed to the door. The rotating component is provided with a push-pull slide rail, which is arranged around the rotation axis of the rotating component. The two ends of the push-pull slide rail are at different distances from the rotation axis of the rotating component. The push-pull component is connected to the sliding component and slidably connected to the push-pull slide rail.

[0033] The aforementioned lifting and sealing structure allows the sealing seat to slide towards or away from the floor onto the door. The sealing seat has a telescopic through-hole, the extension direction of which intersects the sliding direction of the sealing seat. A sliding member is positioned at the telescopic through-hole, with both ends slidably connected to the door, thus supporting the sealing seat. A lifting member connects to the sliding member and is also connected to the wall of the telescopic through-hole. The sliding direction of the sliding member is parallel to the extension direction of the telescopic through-hole. The lifting member is configured to push the sealing seat towards or away from the floor when the sliding member slides on the door. This ensures that when the sliding member slides through the telescopic through-hole, it drives the lifting member to slide relative to the through-hole, and pushes the sealing seat towards or away from the floor. This effectively ensures the soundproof door can be raised and lowered, and also ensures sound insulation. The soundproof door effectively insulates by further coordinating with a rotating component that is rotatably connected to the door. The rotation axis of the rotating component intersects with the extension direction of the telescopic through-hole. The rotating component is located at the end of the sliding component and exposed outside the door, allowing the rotating component to be adjusted from outside the door. The rotating component is equipped with a push-pull track, which is arranged around the rotation axis of the rotating component. The two ends of the push-pull track are at different distances from the rotation axis of the rotating component. The push-pull component is connected to the sliding component and slidably connected to the push-pull track. This causes the position of the push-pull component on the push-pull track to change when the rotating component rotates. Since the two ends of the push-pull track are at different distances from the rotation axis of the rotating component, the push-pull component drives the sliding component to move closer to and further away from the rotating component. Furthermore, without the use of a spring, this effectively ensures the stable lifting and lowering of the sealing seat, thus ensuring the smooth opening and closing of the soundproof door.

[0034] To better understand the lifting and sealing structure of this application, the following further explanation is provided:

[0035] Please refer to the following: Figures 1 to 4 One embodiment of the lifting and sealing structure 10 includes a sealing seat 100, a sliding member 200, a lifting member 300, a rotating member 400, and a push-pull member 500. The sealing seat 100 is disposed between a door 20 and a floor 30. The sealing seat 100 is slidably connected to the door 20 in a direction away from or towards the floor 30. The sealing seat 100 has a telescopic through-hole 101, the extension direction of which intersects the sliding direction of the sealing seat 100. The sliding member 200 is disposed at the telescopic through-hole 101, and both ends of the sliding member 200 are slidably connected to the door 20. The lifting member 300 is connected to the sliding member 200 and also connected to the wall of the telescopic through-hole 101. The sliding direction of the sliding member 200 is parallel to the extension direction of the telescopic through-hole 101. The lifting member 300 is configured to push the sealing seat 100 to move in a direction closer to or away from the floor 30 when the sliding member 200 slides on the door 20. The rotating component 400 is rotatably connected to the door 20. The rotation axis of the rotating component 400 intersects the extension direction of the telescopic through hole 101. The rotating component 400 is disposed at the end of the sliding component 200 and exposed in the door 20. The rotating component 400 is provided with a push-pull slide 401, which is arranged around the rotation axis of the rotating component 400. The two ends of the push-pull slide 401 are at different distances from the rotation axis of the rotating component 400. The push-pull component 500 is connected to the sliding component 200 and slidably connected to the push-pull slide 401.

[0036] The aforementioned lifting and sealing structure 10 allows the sealing seat 100 to slide on the door 20 in a direction closer to or further away from the floor 30. The sealing seat 100 has a telescopic through-hole 101, the extension direction of which intersects the sliding direction of the sealing seat 100. A sliding member 200 is positioned at the telescopic through-hole 101, and both ends of the sliding member 200 are slidably connected to the door 20, thus providing support for the sealing seat 100. The lifting member 300 is connected to the sliding member 200, and the lifting member 300 also... The wall of the telescopic through-hole 101 is connected, and the sliding direction of the sliding member 200 is parallel to the extension direction of the telescopic through-hole 101. The lifting member 300 is configured to push the sealing seat 100 towards or away from the floor 30 when the sliding member 200 slides on the door 20. This ensures that when the sliding member 200 slides in the telescopic through-hole 101, it drives the lifting member 300 to slide relative to the telescopic through-hole 101, and pushes the sealing seat 100 towards or away from the floor 30, thus effectively ensuring the raising and lowering of the soundproof door. This ensures effective sound insulation of the soundproof door. Furthermore, the rotating component 400 is rotatably connected to the door 20. The rotation axis of the rotating component 400 intersects the extension direction of the telescopic through-hole 101. The rotating component 400 is located at the end of the sliding component 200 and exposed outside the door 20, allowing the rotating component 400 to be adjusted from outside the door 20. The rotating component 400 is equipped with a push-pull slide rail 401, which is arranged around the rotation axis of the rotating component 400. The distance between the two ends of the push-pull slide rail 401 and the rotation axis of the rotating component 400 is... The push-pull member 500 is connected to the sliding member 200 and slidably connected to the push-pull track 401. This causes the position of the push-pull member 500 on the push-pull track 401 to change when the rotating member 400 rotates. The two ends of the push-pull track 401 are at different distances from the rotation axis of the rotating member 400. In this way, the push-pull member 500 drives the sliding member 200 to move closer to and further away from the rotating member 400. Without the use of a spring, this effectively ensures the stable lifting and lowering of the sealing seat 100, thereby ensuring the smooth opening and closing of the soundproof door.

[0037] In one embodiment, the extension direction of the telescopic through-hole 101 is perpendicular to the sliding direction of the sealing seat 100.

[0038] Please refer to the following: Figures 2 to 4In one embodiment, door 20 is rotatably connected to door frame 40, and door 20 is movably covered by door frame 40. Further, door frame 40 is provided with a meshing track 4001, the extension direction of meshing track 4001 intersecting the rotation axis of door 20, and the extension direction of meshing track 4001 being parallel to the thickness direction of door 20 when door 20 is covered by door frame 40. Further, rotating member 400 is provided with a meshing member 600, the meshing member 600 being arranged around the rotation axis of rotating member 400, and a portion of meshing member 600 protruding from door 20 and detachably meshing with meshing track 4001. It is understandable that when the door 20 is movably covered by the door frame 40, the push-pull member 500 is positioned near one end of the push-pull track 401, which is farther from the rotation axis of the rotating member 400. When the door 20 is further rotated by external force, the engaging part slides on the engaging track 4001, causing the rotating member 400 to rotate relative to the door 20. The push-pull member 500 slides towards the other end of the push-pull track, thus causing the sliding member 200 to move closer to the rotating member 400. At this time, the lifting member 300 pushes the sealing seat 100 towards the floor 30. Conversely, when the door 20 is not covered by the door frame 40, the push-pull member... The push-pull slide 401, which is close to the rotation axis of the rotating member 400, is set in a section. When the door 20 is covered by the door frame 40 by external force, the engaging part slides on the engaging track 4001, causing the rotating member 400 to rotate in the opposite direction relative to the door 20. The push-pull member 500 slides towards the other end of the push-pull slide, and the push-pull member 500 drives the sliding member 200 to move away from the rotating member 400. At this time, the lifting member 300 pushes the sealing seat 100 to move away from the floor 30, effectively ensuring the stable lifting and lowering of the sealing seat 100, thereby ensuring the smooth opening and closing of the soundproof door.

[0039] In one embodiment, the direction of extension of the engagement track is perpendicular to the rotation axis of the door.

[0040] Please refer to the following: Figure 3 , Figure 5 and Figure 6In one embodiment, the lifting member 300 includes a first lifting portion 310 and a second lifting portion 320, which are connected one-to-one to the wall of the telescopic through hole 101 and the sliding member 200, and are correspondingly arranged. Further, when the rotating member 400 rotates, the first lifting portion 310 is configured to move towards or away from the second lifting portion 320, so that the sliding member 200 drives the sealing seat 100 to move towards or away from the floor 30. It can be understood that the push-pull member 500 moves towards or away from the rotating member 400, thereby causing the sliding member 200 to move towards or away from the rotating member 400, thus changing the relative position between the first lifting portion 310 and the second lifting portion 320. Furthermore, it can be understood that when the door 20 is movably covered by the door frame 40, the push-pull member 500 is positioned near one end of the push-pull track 401, which is farther from the rotation axis of the rotating member 400. When the door 20 is rotated by external force, the engaging part slides on the engaging track 4001, causing the rotating member 400 to rotate relative to the door 20. The push-pull member 500 slides towards the other end of the push-pull track, thereby causing the sliding member 200 to move closer to the rotating member 400. At this time, the first lifting part 310 moves closer to the second lifting part 320, and the sealing seat 100 moves closer to the floor 30 via the sliding member 200. Conversely, when the door 20 is not covered by the door frame 40, The push-pull member 500 is positioned near a section of the push-pull slide rail 401 that is close to the rotation axis of the rotating member 400. When the door 20 is placed on the door frame 40 by external force, the engaging part slides on the engaging track 4001, causing the rotating member 400 to rotate in the opposite direction relative to the door 20. The push-pull member 500 slides towards the other end of the push-pull slide rail, thereby causing the sliding member 200 to move away from the rotating member 400. At this time, the first lifting part 310 moves away from the second lifting part 320, and the sealing seat 100 moves away from the floor 30 via the sliding member 200, effectively ensuring the stable lifting and lowering of the sealing seat 100, thereby ensuring the smooth opening and closing of the soundproof door.

[0041] Please refer to the following: Figures 2 to 3In one embodiment, the first lifting part 310 has a first wedge-shaped surface 301 on the side near the second lifting part 320, and the second lifting part 320 has a second wedge-shaped surface 302 on the side near the first lifting part 310. The first wedge-shaped surface 301 and the second wedge-shaped surface 302 are slidably connected. Further, in at least another embodiment, the first and second lifting parts are magnets. The magnetic poles of the first lifting part near the second lifting part are the same as the magnetic poles of the second lifting part near the first lifting part. This better ensures that when the sliding member moves towards or away from the rotating member, the first lifting part moves stably towards or away from the second lifting part, thereby enabling the sealing seat to move towards or away from the floor. This ensures that the soundproof door can be effectively raised and lowered while maintaining sound insulation, thus ensuring the effective opening and closing of the soundproof door.

[0042] In one embodiment, the first lifting part and the sealing seat are integrally formed. Furthermore, the second lifting part and the sliding member are integrally formed, improving the structural compactness and stability of the lifting sealing structure, thereby further ensuring the stability of the soundproof door during lifting and lowering, and reducing the processing steps of the lifting sealing structure, thus improving its processing efficiency.

[0043] Please refer to the following: Figure 3 and Figure 5 In one embodiment, the sliding member 200 is provided with a rotation clearance groove 201 at one end near the rotating member 400. The rotating member 400 is partially housed in the rotation clearance groove 201 and is used to set the push-pull slide 401. The push-pull member 500 is disposed in the rotation clearance groove 201 and slidably connected to the push-pull slide 401. It is understandable that, since both ends of the sliding member 200 need to be supported by the door 20 during the rotation of the rotating member 400, and the rotating member 400 also needs the door 20 as an installation platform for installation, and since the rotating member 400 is located at the end of the sliding member 200, both the rotating member 400 and the sliding member 200 need to occupy the door 20 for installation. If the rotating member 400 and the sliding member 200 are spaced apart, the thickness of the part of the door 20 used for installing the rotating member 400 and the sliding member 200 needs to be larger. This would further increase the weight of the door 20 and occupy the space inside the door 20 used for noise reduction. Therefore, a rotation clearance groove 201 is provided at the end of the sliding member 200 near the rotating member 400, so that the space occupied by the sliding member 200 and the rotating member 400 in the door 20 overlaps. This ensures that the sliding member 200 is effectively connected to the rotating member 400 through the pusher, improves the weight of the door 20, and ensures that there is a large space inside the door 20 for noise reduction.

[0044] Please refer to the following: Figure 3 , Figure 5 and Figure 6In one embodiment, the push-pull slide 401 is a push-pull sliding hole, the depth direction of which is parallel to the rotation axis of the rotating member 400. The two ends of the push-pull member 500 protrude from the push-pull sliding hole and are connected to the two groove walls of the rotation clearance groove 201, which improves the sliding stability of the push-pull member 500 at the push-pull slide 401, and further improves the stability of the lifting and lowering of the sealing seat 100.

[0045] This application also provides a soundproof door. One embodiment of the soundproof door includes a door, a door frame, and a lifting and sealing structure as described in any of the above embodiments. The door is rotatably connected to the door frame, and the door movably covers the door frame. A sealing seat is disposed between the door and the floor, and is slidably connected to the door in a direction away from or towards the floor. Both ends of a sliding member are slidably connected to the door. A lifting member is configured to push the sealing seat to move in a direction towards or away from the floor when the sliding member slides on the door. Further, a rotating member is rotatably connected to the door, and is disposed at the end of the sliding member and exposed outside the door. Further details are also available in the following sections. Figures 1 to 4 In this embodiment, the lifting and sealing structure 10 includes a sealing seat 100, a sliding member 200, a lifting member 300, a rotating member 400, and a push-pull member 500. The sealing seat 100 is disposed between the door 20 and the floor 30. The sealing seat 100 is slidably connected to the door 20 in a direction away from or towards the floor 30. The sealing seat 100 has a telescopic through-hole 101, the extension direction of which intersects the sliding direction of the sealing seat 100. The sliding member 200 is disposed at the telescopic through-hole 101, and both ends of the sliding member 200 are slidably connected to the door 20. The lifting member 300 is connected to the sliding member 200 and also connected to the wall of the telescopic through-hole 101. The sliding direction of the sliding member 200 is parallel to the extension direction of the telescopic through-hole 101. The lifting member 300 is configured to push the sealing seat 100 to move in a direction closer to or away from the floor 30 when the sliding member 200 slides on the door 20. The rotating component 400 is rotatably connected to the door 20. The rotation axis of the rotating component 400 intersects the extension direction of the telescopic through hole 101. The rotating component 400 is disposed at the end of the sliding component 200 and exposed in the door 20. The rotating component 400 is provided with a push-pull slide 401, which is arranged around the rotation axis of the rotating component 400. The two ends of the push-pull slide 401 are at different distances from the rotation axis of the rotating component 400. The push-pull component 500 is connected to the sliding component 200 and slidably connected to the push-pull slide 401.

[0046] The aforementioned soundproof door employs a lifting and sealing structure, which effectively ensures the stable raising and lowering of the sealing seat, thereby ensuring the smooth opening and closing of the soundproof door.

[0047] Compared with the prior art, the present invention has at least the following advantages:

[0048] The lifting and sealing structure 10 of this utility model allows the sealing seat 100 to slide and connect to the door 20 in a direction closer to or further away from the floor 30. The sealing seat 100 has a telescopic through hole 101, the extension direction of which intersects the sliding direction of the sealing seat 100. A sliding member 200 is disposed at the telescopic through hole 101, and both ends of the sliding member 200 are slidably connected to the door 20, thus enabling the sliding member 200 to support the sealing seat 100. The lifting member 300 is connected to the sliding member 200. It is also connected to the wall of the telescopic through-hole 101. The sliding direction of the sliding member 200 is parallel to the extension direction of the telescopic through-hole 101. The lifting member 300 is configured to push the sealing seat 100 toward the floor 30 when the sliding member 200 slides on the door 20. That is, when the sliding member 200 slides on the telescopic through-hole 101, it drives the lifting member 300 to slide relative to the telescopic through-hole 101, and pushes the sealing seat 100 toward the floor 30 through the lifting member 300, thus better ensuring the effective lifting and lowering of the soundproof door. The soundproof door is effectively soundproofed, and the rotating component 400 is rotatably connected to the door 20. The rotation axis of the rotating component 400 intersects the extension direction of the telescopic through hole 101. The rotating component 400 is located at the end of the sliding component 200 and exposed outside the door 20, allowing the rotating component 400 to be rotated and adjusted outside the door 20. The rotating component 400 is equipped with a push-pull slide rail 401, which is arranged around the rotation axis of the rotating component 400. The distance between the two ends of the push-pull slide rail 401 and the rotation axis of the rotating component 400 is... In contrast, the push-pull member 500 is connected to the sliding member 200 and slidably connected to the push-pull track 401. This causes the position of the push-pull member 500 on the push-pull track 401 to change when the rotating member 400 rotates. The distances between the two ends of the push-pull track 401 and the rotation axis of the rotating member 400 are different. In this way, the push-pull member 500 drives the sliding member 200 to move towards and away from the rotating member 400. Without the use of a spring, the stable lifting and lowering of the sealing seat 100 is effectively ensured, thereby ensuring the smooth opening and closing of the soundproof door.

[0049] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
