Description

Technical Field

[0001] This utility model relates to the field of noise shielding technology, and in particular to a thresholdless soundproof door. Background Technology

[0002] In various locations with strict noise control requirements, soundproof doors are crucial for blocking sound transmission. However, existing soundproof doors have significant limitations in their bottom sealing design, especially those used without thresholds. Most rely on static rubber strips directly adhering to the ground, a method highly susceptible to surface unevenness. Even minor bumps or depressions in the ground can create gaps in the seal, drastically reducing sound insulation. Furthermore, with prolonged use, the rubber strips easily wear down and age, losing elasticity and further exacerbating sealing failure, making it difficult to maintain stable sound insulation performance.

[0003] Furthermore, traditional soundproof doors have shortcomings in their overall sound insulation design. The fit between the door frame and the door leaf often uses a single sealing structure, which makes it difficult to form multiple sound barriers, allowing sound to easily leak through the gaps between them. In addition, the door leaf itself lacks structural rigidity and is prone to deformation after long-term use, further widening the gaps, resulting in overall sound insulation efficiency that is insufficient to meet the needs of high-requirement applications. Utility Model Content To overcome the above-mentioned shortcomings, the purpose of this utility model is to provide a thresholdless soundproof door with a simple structure and good sound insulation effect.

[0004] This utility model discloses a thresholdless soundproof door, including a door frame and a door panel rotatably connected to the door frame and disposed within the door frame. The door panel is hollow and includes a first panel and a second panel disposed opposite to each other. The bottom and / or top of the door panel are provided with guide grooves along a second direction. A first sealing element is installed in the guide groove. A driving unit is provided between the first panel and the second panel. The driving end of the driving unit is connected to a transmission unit. The transmission unit is connected to the first sealing element in the guide groove to control the first sealing element to move closer to or away from the door frame.

[0005] In one or more embodiments of the present invention, the door frame includes a first outer frame and a second outer frame arranged along a second direction, and a top frame disposed between the first outer frame and the second outer frame, wherein the first outer frame and the second outer frame are provided with a second sealing member.

[0006] In one or more embodiments of the present invention, the driving unit includes a rotating component rotatably disposed on a first panel, and a gear is connected to the end of the rotating component, the gear being connected to a transmission unit for transmission.

[0007] In one or more embodiments of the present invention, the transmission unit includes a first transmission component and a second transmission component, wherein the first transmission component and the second transmission component are disposed on both sides of the gear and are connected to it in a transmission manner.

[0008] In one or more embodiments of this utility model, the first transmission assembly and the second transmission assembly have the same structure. The first transmission assembly includes a rack, a connecting plate, a mounting plate, and a first seal. The rack is slidably mounted on the inner side of the second panel along a second direction and meshes with the gear. The rack is fixedly mounted on the connecting plate. The connecting plate is slidably mounted on the second panel along a second direction. The end of the connecting plate is connected to a mounting plate arranged along a first direction. The first seal is mounted on the mounting plate.

[0009] In one or more embodiments of this utility model, a guide hole is provided on the rack along a third direction, a guide shaft is provided in the guide hole, and the guide shaft is installed between the first panel and the second panel.

[0010] In one or more embodiments of this utility model, a first partition plate and a second partition plate are provided on the inner side of the second panel. The first partition plate and the second partition plate together with the first panel and the second panel respectively form a sound insulation cavity, and a sound insulation filling material is provided in the sound insulation cavity.

[0011] In one or more embodiments of this utility model, the door frame and the door panel are locked together by a locking unit, the locking unit including a first door lock assembly and a second door lock assembly respectively disposed on a first panel and a second panel.

[0012] In one or more embodiments of the present invention, the first door lock assembly and the second door lock assembly include a handle, the end of the handle being provided with a locking pin, the locking pin cooperating with a locking plate disposed on the door frame.

[0013] In one or more embodiments of this utility model, the sides of the first outer frame and the second outer frame that are in contact with the door panel are both set in a stepped shape, and at least two sets of second sealing elements are provided on the first outer frame and the second outer frame.

[0014] The beneficial effects of this utility model are as follows: By setting a driveable telescopic first sealing element at the bottom and / or top of the door panel, and by utilizing the cooperation of the transmission unit and the drive unit, the automatic telescopic adjustment of the sealing element can be realized. This can effectively adapt to changes in the flatness of different ground surfaces, avoid the problem of gaps formed by traditional static sealing strips due to uneven ground surfaces, thereby significantly improving the sealing stability and sound insulation performance of the bottom of the door, and maintaining a good sealing effect even after long-term use.

[0015] This invention employs a multi-layered sealing structure at the junction of the door frame and door panel, and incorporates a sound-insulating cavity and filling material within the door panel, forming a multi-layered sound barrier that significantly reduces the possibility of sound transmission through gaps and structures. Compared to traditional single-seal structures, this design not only improves overall sound insulation efficiency but also maintains stable sound insulation performance in high-noise environments, meeting the needs of demanding environments such as recording studios and laboratories.

[0016] The door panel structure of this utility model is hollow and equipped with a reinforcing partition plate, which not only improves the overall rigidity of the door body and reduces the risk of sound leakage caused by door panel deformation during long-term use, but also ensures that the door leaf and door frame remain tightly fitted when closed by reliable locking unit, effectively preventing sound wave leakage, further extending the service life of the thresholdless soundproof door and reducing maintenance costs.

The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0022] As described in the background section, existing door frames and door panels often use a single sealing structure, which makes it difficult to form multiple sound barriers. Sound can easily leak from the gap between the two, and existing soundproof doors are difficult to meet the sound insulation requirements of door frames without thresholds.

[0023] For the above issues, please refer to the appendix. Figures 1-10As shown, this utility model provides a thresholdless soundproof door, including a door frame 100 and a door panel 200 rotatably connected to and disposed within the door frame 100. The door panel 200 has a hollow structure and includes a first panel 201 and a second panel 202 disposed opposite to each other. A guide groove 2021 is provided at the bottom and / or top of the door panel 200 along the second direction Z, and a retractable first sealing member 504 is installed in the guide groove 2021. A drive unit 400 is disposed between the first panel 201 and the second panel 202. The drive end of the drive unit 400 is connected to a transmission unit 500, and the transmission unit 500 is connected to the first sealing member 504 in the guide groove 2021, for controlling the first sealing member 504 to move closer to or further away from the door frame 100 to adjust the sealing state. In this embodiment, the first sealing member 504 is a sealing member made of D-type wear-resistant material.

[0024] In this embodiment, the door frame 100 includes a first outer frame 101 and a second outer frame 102 arranged along the second direction Z, and a top frame 103 located between the first outer frame 101 and the second outer frame 102. A second sealing element 700 is provided on both the first outer frame 101 and the second outer frame 102 to cooperate with the door panel 200 to form a multiple seal. Preferably, the side of the first outer frame 101 and the second outer frame 102 that contacts the door panel 200 is configured with a stepped structure, and at least two sets of second sealing elements 700 can be provided at the stepped positions to further improve the sealing and sound insulation effects.

[0025] In a further embodiment, the drive unit 400 includes a rotating member 401 rotatably disposed on the first panel 201, and a gear 402 is fixedly connected to the end of the rotating member 401. The gear 402 is meshed with the transmission unit 500 and is used to transmit the rotational motion of the rotating member 401 to the transmission unit 500 to drive the first seal 504 to extend or retract.

[0026] In a further embodiment, the transmission unit 500 includes a first transmission assembly 51 and a second transmission assembly 52 located on both sides of the gear 402. The first transmission assembly 51 and the second transmission assembly 52 have the same structure. Taking the first transmission assembly 51 as an example, it includes a rack 501, a connecting plate 502, a mounting plate 503, and a first seal 504. The rack 501 is slidably mounted on the inner side of the second panel 202 along the second direction Z and meshes with the gear 402. The rack 501 is fixedly mounted on the connecting plate 502, which is slidably mounted in the second panel 202 along the second direction Z. The end of the connecting plate 502 is connected to the mounting plate 503 arranged along the first direction X, and the first seal 504 is fixedly mounted on the mounting plate 503. In this embodiment, the first transmission assembly 51 and the second transmission assembly 52 can press the first seal 500 at the upper and lower positions of the door panel 200 to achieve sealing at the upper and lower positions, and the sealing effect is further improved by cooperating with the second seals 700 on the left and right sides.

[0027] In a further embodiment, to ensure the smoothness of the rack 501 during transmission, the rack 501 is provided with a guide hole 5021 along a third direction, and a guide shaft 505 is provided in the guide hole 5021. The two ends of the guide shaft 505 are respectively installed between the first panel 201 and the second panel 202, thereby limiting the swing of the rack 501 and ensuring the smooth movement of the seal 504 and the uniformity of the seal.

[0028] To improve the overall sound insulation performance of the door panel 200, a first partition plate 601 and a second partition plate 602 are provided on the inner side of the second panel 202. The first partition plate 601 and the second partition plate 602 cooperate with the first panel 201 and the second panel 202 respectively to form a sound insulation cavity.
