Description

Technical Field

[0001] The utility model relates to the technical field of noise shielding, in particular to an arched sound insulation door. Background Art

[0002] In the prior art, such as patent CN202311174836, a hole is opened on one side of the sound insulation wall, and then a rectangular sound insulation door is used for noise shielding to facilitate the entry and exit of staff.

[0003] In actual applications, the opening will inevitably increase after multiple removal and installation of door panels, and it is difficult to maintain the original regular rectangular shape. In particular, the extra opening at the top is the most difficult to repair. The holes on both sides and below can be repaired with the same materials as the wall, and the joints can be treated with structural adhesive, foaming agent and cement. The holes directly above need to consider the load-bearing problem of the door panel and door frame, so it is difficult to use sound insulation wall materials, but filling with lightweight materials is difficult to meet the basic sound insulation requirements. Utility Model Content

[0004] In order to overcome the above-mentioned shortcomings, the purpose of the utility model is to provide an arched soundproof door which can meet the load-bearing requirements of the door panel and the door frame, and can also meet the sound insulation requirements.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is: an arched soundproof door, comprising a door frame and a door panel, wherein the door frame and the door panel are hinged, and characterized in that: the upper end surface of the door frame is in an arc shape so that the door frame is in an arched shape; two door panels are provided, namely a first door panel and a second door panel, and the upper end surfaces of the two door panels are both in an arc shape so that the entire door panel is in an arched shape after the two door panels are closed;

[0006] A sealing structure is arranged on opposite sides of the two door panels, and the sealing structure includes a first sealing ring arranged on the first door panel and a second sealing ring arranged on the second door panel. A first pressure plate is arranged at a position corresponding to the second sealing ring on the first door panel, and a second pressure plate is arranged at a position corresponding to the first sealing ring on the second door panel. When the first door panel and the second door panel are in a closed state, the first pressure plate presses the second sealing ring and the second pressure plate presses the first sealing ring.

The present application can meet both the load-bearing requirements of the door panel and door frame and the sound insulation requirements, solving the technical problem that the prior art cannot take both into account.

[0008] Furthermore, the first sealing ring and the second sealing ring are both hollow sealing rings. Compared with solid sealing rings, hollow sealing rings are more likely to deform and rebound under the pressure of the pressure plate, thereby achieving a better sealing effect.

[0009] Furthermore, the thickness of the first sealing ring and the second sealing ring is 2-3 mm.

[0010] Furthermore, the distance between the bottom end of the first pressing plate and the bottom edge of the inner ring of the second sealing ring is less than the thickness of the second sealing ring; the distance between the top end of the second pressing plate and the top edge of the inner ring of the first sealing ring is less than the thickness of the first sealing ring.

[0013] Furthermore, a first reinforcing member is arranged on the first door panel, and the first reinforcing member is arranged on a side of the fourth sealing ring away from the third sealing ring.

[0014] Furthermore, the third sealing assembly includes a fifth sealing ring arranged on the door frame, a sixth sealing ring arranged on the second door panel and a fourth pressure plate, and when the second door panel is in a closed state relative to the door frame, the fourth pressure plate presses the fifth sealing ring and the fifth sealing ring contacts the sixth sealing ring.

[0015] Furthermore, a second reinforcing member is arranged on the second door panel, and the second reinforcing member is arranged on a side of the sixth sealing ring away from the fifth sealing ring.

[0016] Furthermore, door handles are provided on both the first door panel and the second door panel.

[0017] The beneficial effect of the utility model is that the door frame and door panel in the present application are arranged in an arch shape to meet the load-bearing requirements of the door panel and door frame, increase the area of ​​the opening, that is, increase the area for people or objects to pass through, and the sealing structure arranged between the two door panels in the present application can meet the sound insulation requirements. The present application can meet both the load-bearing requirements of the door panel and door frame and the sound insulation requirements, solving the technical problem that the two cannot be taken into account in the prior art. Compared with the use of solid sealing rings, the use of hollow sealing rings is more likely to deform and rebound under the compression state of the pressure plate, thereby achieving a better sealing effect.

For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0028] See attached Figure 1 As shown, an embodiment of the present application provides an arched soundproof door, which includes a door frame 1 and a door panel, wherein the door frame 1 and the door panel are hinged, the upper end surface of the door frame 1 is arc-shaped so that the door frame 1 is in an arched shape, and two door panels are provided, namely a first door panel 3 and a second door panel 4, and the upper end surfaces of the two door panels are both arc-shaped so that the entire door panel is in an arched shape when the two door panels are closed.

[0029] The present application does not limit the diameter of the arc shape of the upper end surface of the door frame 1 and the arc shape of the upper end surface of the door panel. It is set according to the opening shape of the top of the hole. The arc shape of the upper end surface of the door frame 1 and the arc shape of the upper end surface of the door panel can be a flat arc shape or a steep arc shape.

[0030] like Figure 2 , Figure 3 As shown, a sealing structure 5 is provided on opposite sides of the two door panels, and the sealing structure 5 includes a first sealing ring 501 provided on the first door panel 3 and a second sealing ring 502 provided on the second door panel 4, a first pressure plate 503 is provided at a position corresponding to the second sealing ring 502 on the first door panel 3, and a second pressure plate 504 is provided at a position corresponding to the first sealing ring 501 on the second door panel 4, and when the first door panel 3 and the second door panel 4 are in a closed state, the first pressure plate 503 presses the second sealing ring 502 and the second pressure plate 504 presses the first sealing ring 501.

[0031] The first sealing ring 501 and the second sealing ring 502 are sealing rings made of soft materials and can be deformed under the pressure of the pressure plate. In this embodiment, the first sealing ring 501 and the second sealing ring 502 are rubber sealing rings.

[0032] During the closing process of the first door panel 3 and the second door panel 4, the first pressure plate 503 gradually contacts the second sealing ring 502, and the second pressure plate 504 gradually contacts the first sealing ring 501. As the first door panel 3 and the second door panel 4 are gradually closed, the first pressure plate 503 gradually squeezes the second sealing ring 502 to deform the second sealing ring 502 until the first door panel 3 and the second door panel 4 are closed. At this time, the first pressure plate 503 presses the second sealing ring 502, and similarly, the second pressure plate 504 presses the first sealing ring 501. At the same time, the first sealing ring 501 contacts the second sealing ring 502 to achieve the maximum sound insulation effect.

[0033] The door frame 1 and the door panel in the present application are arranged in an arch shape to meet the load-bearing requirements of the door panel and the door frame 1, increase the area of ​​the opening, that is, increase the area for people or objects to pass through, and the sealing structure arranged between the two door panels in the present application can meet the sound insulation requirements. The present application can meet both the load-bearing requirements of the door panel and the door frame 1 and the sound insulation requirements, solving the technical problem that the two cannot be taken into account in the prior art.

[0034] On the basis of the above, the first sealing ring 501 and the second sealing ring 502 are both hollow sealing rings. If a solid sealing ring is used, the sealing effect can also be achieved, but the rebound effect of the sealing ring is poor after the pressure plate presses the sealing ring, and a concave shape will be formed, so that the sealing effect is not very good. Compared with a solid sealing ring, a hollow sealing ring is more likely to deform and rebound under the pressure of the pressure plate, so that the sealing effect is better.

[0035] On the basis of the above, the thickness of the first sealing ring 501 and the second sealing ring 502 is 2-3 mm. The thickness of the first sealing ring 501 and the second sealing ring 502 mentioned here refers to the single layer thickness of the first sealing ring 501 and the second sealing ring 502, not the overall thickness of the first sealing ring 501 and / or the second sealing ring 502. The thickness of the first sealing ring 501 and the second sealing ring 502 can be 2 mm, 2.5 mm or 3 mm. In this embodiment, the thickness of the first sealing ring 501 and the second sealing ring 502 are both 2.5 mm.

[0036] On the basis of the above, if Figure 4 , Figure 5As shown, the distance A between the bottom end of the first pressure plate 503 and the bottom edge of the inner ring of the second sealing ring 502 is smaller than the thickness B of the second sealing ring 502; the distance C between the top end of the second pressure plate 504 and the top edge of the inner ring of the first sealing ring 501 is smaller than the thickness D of the first sealing ring 501, so that when the first door panel 3 and the second door panel 4 are in a closed state, the first pressure plate 503 can press the second sealing ring 502 and the second pressure plate 504 can press the first sealing ring 501, thereby preventing the first sealing ring 501 and / or the second sealing ring 502 from not being pressed, causing gaps at the inner rings of the first sealing ring 501 and / or the second sealing ring 502, thereby causing poor sealing effect.

[0037] On the basis of the above, if Figure 2 As shown, a second sealing component 6 is provided between the door frame 1 and the first door panel 3, and the second sealing component 6 is used to achieve sealing between the first door panel 3 and the door frame 1. A third sealing component 7 is provided between the door frame 1 and the second door panel 4, and the third sealing component 7 is used to achieve sealing between the second door panel 4 and the door frame 1, so that the sound insulation effect of the arched soundproof door is better.

[0038] On the basis of the above, if Figure 6 As shown, the second sealing assembly 6 includes a third sealing ring 601 arranged on the door frame 1, a fourth sealing ring 602 and a third pressure plate 603 arranged on the first door panel 3. When the first door panel 3 is in a closed state relative to the door frame 1, the third pressure plate 603 presses the third sealing ring 601 and the third sealing ring 601 contacts the fourth sealing ring 602, so as to seal the gap between the door frame 1 and the first door panel 3, thereby improving the sealing effect of the soundproof door.

[0039] On the basis of the above, if Figure 6 As shown, the first door panel 3 is provided with a first reinforcement member 604, which is arranged on the side of the fourth sealing ring 602 away from the third sealing ring 601. The first reinforcement member 604 is used to reinforce the fourth sealing ring 602 to prevent the fourth sealing ring 602 from being displaced when the first door panel 3 is closed, so that the third sealing ring 601 can fully contact with the fourth sealing ring 602 when the first door panel 3 is closed, thereby ensuring the sealing effect of the soundproof door and thus ensuring the soundproof effect. The first reinforcement member 604 is made of hard material. In this embodiment, the first reinforcement member 604 is made of the same material as the door panel, that is, stainless steel.

[0040] On the basis of the above, if Figure 7As shown, the third sealing assembly 7 includes a fifth sealing ring 701 arranged on the door frame 1, a sixth sealing ring 702 and a fourth pressure plate 703 arranged on the second door panel 4. When the second door panel 4 is in a closed state relative to the door frame 1, the fourth pressure plate 703 presses the fifth sealing ring 701 and the fifth sealing ring 701 contacts the sixth sealing ring 702, so as to seal the gap between the door frame 1 and the second door panel 4, thereby improving the sound insulation effect of the sound insulation door.

[0041] On the basis of the above, a second reinforcing member 704 is provided on the second door panel 4, and the second reinforcing member 704 is provided on the side of the sixth sealing ring 702 away from the fifth sealing ring 701. The second reinforcing member 704 is used to reinforce the sixth sealing ring 702 to prevent the sixth sealing ring 702 from being displaced when the second door panel 4 is closed. The purpose is to ensure that the fifth sealing ring 701 can fully contact the sixth sealing ring 702 when the first door panel 3 is closed, thereby ensuring the sealing effect of the soundproof door and thus the soundproof effect.

[0042] On the basis of the above, the first door panel 3 and the second door panel 4 are both provided with door handles 8 to facilitate closing and opening of the first door panel 3 and the second door panel 4 .

[0043] The above implementation modes are only for illustrating the technical concept and features of the utility model, and their purpose is to allow people familiar with this technology to understand the content of the utility model and implement it. It cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
