Description

Technical Field

[0001] This utility model relates to the field of soundproof doors for factory buildings, specifically a soundproof door for industrial factory buildings. Background Technology

[0002] Traditional factories typically generate significant noise during manufacturing processes, necessitating soundproof doors to prevent this noise from escaping. However, while these soundproof doors effectively block noise, a large portion of the noise still leaks out. Furthermore, the heavy soundproof doors are prone to damaging the frame and generating considerable noise when closed.

[0003] Document CN 215369451 U discloses a top-mounted inclined rail type folding swing soundproof industrial door, including a door frame, a door edge plate that is snapped into the upper part of the door frame, a T-shaped groove that runs through the opening of the door edge plate downwards, a first sliding door, a second sliding door, and a third sliding door that are snapped into the lower part of the T-shaped groove, a first sliding groove and a second sliding groove that are opened in the lower part of the door frame, a drain pipe that is fixedly installed in the middle of the first sliding groove and leads to the outside, and several through holes that are connected to the drain pipes in the first sliding groove and the third sliding door are respectively placed on both sides of the first sliding groove, and the second sliding door is placed in the middle of the second sliding groove. When this structure is used for sound insulation of the factory building, the sound insulation effect is not very good due to the simple internal structure of the soundproof door.

[0004] Therefore, a new technical solution is needed to solve the above-mentioned technical problems. Summary of the Invention

[0005] To address the aforementioned problems, this utility model discloses a soundproof door for industrial plants, which improves the overall sound insulation effect through sound-absorbing cotton and increases the overall service life through springs in the door frame.

[0006] The technical solution of this utility model is as follows: a soundproof door for industrial plants, including a soundproof door body located inside the door frame body. The soundproof door body is located inside the door frame body. The side of the door frame body is provided with an inward convex edge. The side of the soundproof door body and the convex edge are adapted to each other. A buffer structure is provided on the convex edge. The buffer structure includes a spring and a buffer cavity. A fireproof door panel is provided inside the soundproof door body. The fireproof door panel is filled with rock wool, a sound insulation board and sound-absorbing cotton.

[0007] By adopting the above technical solution and setting a buffer structure on the door frame body, when the soundproof door body and the door frame body are closed, the impact sound between the two can be reduced as much as possible due to the existence of the buffer structure, thus reducing the sound emission. The sound emitted from inside the factory is absorbed after multiple reflections by the sound-absorbing cotton inside the soundproof panel, achieving the purpose of maximizing sound insulation.

[0008] Preferably, the sound insulation panels are located on both sides inside the soundproof door and are wavy, with the openings of the wavy panels facing each other and the openings between the two wavy sound insulation panels being staggered.

[0009] By adopting the above technical solution, when sound enters, it is reflected multiple times, and the energy of the sound gradually weakens, thereby reducing noise.

[0010] Preferably, the sound-absorbing cotton is located on the upper surface of the sound insulation board, that is, the sound-absorbing cotton is located on the side opposite to the sound insulation board, and the shape of the sound-absorbing cotton is compatible with the shape of the sound insulation board.

[0011] By adopting the above technical solutions, sound-absorbing cotton can absorb sound while it is being reflected, reducing sound reflection and secondary propagation, and improving the overall sound insulation effect.

[0012] Preferably, the recessed part of the sound insulation board is filled with rock wool, and the protruding part of the sound insulation board is fixedly connected to the fireproof door panel.

[0013] By adopting the above technical solution and filling the outside of the sound insulation board with rock wool, sound can be absorbed on the one hand, and on the other hand, rock wool has a fireproof function, which improves the overall fire resistance of the soundproof door.

[0014] Preferably, the sound insulation board, rock wool filling and sound-absorbing cotton are fully enclosed inside the fireproof door panel, and the top and bottom of the fireproof door panel are provided with door panel covers.

[0015] By adopting the above technical solutions, the fireproof door panel isolates the internal structure, reducing the chance of contact with the outside in the event of a fire and improving the safety factor.

[0016] Preferably, the door frame body, except for the side connected to the soundproof door body, is provided with a protruding edge, and springs are sequentially located on the protruding edge. The springs are arranged on both sides along the length direction of the protruding edge, and the top of the spring is located inside the door frame body when it is extended.

[0017] Preferably, the buffer cavities are arranged along the length of the convex edge, the inner side of the buffer cavity abuts against the top of the spring, and the edge of the buffer cavity is connected to the inner side of the upper surface edge of the convex edge.

[0018] By adopting the above technical solution, when the convex edges of the soundproof door body and the door frame body are joined together, the soundproof door body squeezes the buffer cavity and is subjected to the force of the spring, so that the soundproof door can close slowly, reducing the generation of noise while protecting the door frame body of the soundproof door.

[0019] Preferably, when the soundproof door body is closed, the spring and buffer cavity of the door frame body are compressed, and the surface of the soundproof door body is flush with the outer side of the door frame.

[0020] By adopting the above technical solution, when the spring is compressed, that is, when the soundproof door presses down on the door frame body, the compression height of the spring is just enough to make the outer surface of the soundproof door body flush with the outer surface of the door frame body, which makes it easy for the soundproof door body to close.

[0021] The advantages of this utility model are: 1. The spring and buffer cavity on the convex edge of the door frame body can make the spring play a buffering role when the soundproof door body is closed, reducing the noise when the soundproof door is closed, and protecting the door frame body.

[0022] 2. This utility model incorporates sound-absorbing cotton within the sound insulation panel. This cotton not only reduces sound reflection but also absorbs some of the sound, further reducing sound propagation and enhancing the sound insulation effect of the soundproof door.

[0023] 3. The soundproof door of this utility model improves the overall sound insulation effect through sound-absorbing cotton and improves the overall service life through the springs in the door frame. Attached Figure Description

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0030] like Figure 1-4As shown, the soundproof door for industrial plants includes a soundproof door body 9 located inside the door frame body 1. The door frame body 1 has an inwardly protruding edge 2 on its side, which is adapted to the side of the soundproof door body 9 and the protruding edge 2. The protruding edge 2 has a buffer structure, which includes a spring 3 and a buffer cavity. The soundproof door body 9 has a fireproof door panel 5 inside, which is filled with rock wool 8, a sound insulation board 6, and sound-absorbing cotton 7. By setting a buffer structure on the door frame body 1, when the soundproof door body 9 and the door frame body 1 are closed, the impact sound between the two can be reduced as much as possible due to the presence of the buffer structure, thus reducing the sound emission. The sound emitted from inside the plant is absorbed after multiple reflections by the sound-absorbing cotton 7 inside the sound insulation board 6, achieving the purpose of maximizing sound insulation.

[0031] The sound insulation panels 6 are located on both sides inside the soundproof door and are wavy. The openings of the wavy panels are set in opposite directions, and the openings between the two wavy sound insulation panels 6 are staggered. When sound enters, it is reflected multiple times, and the sound energy is gradually weakened, thereby reducing noise.

[0032] The sound-absorbing cotton 7 is located on the upper surface of the sound insulation board 6, that is, the sound-absorbing cotton 7 is located on the side opposite to the sound insulation board 6. The shape of the sound-absorbing cotton 7 is adapted to the sound insulation board 6. The sound-absorbing cotton 7 can absorb the sound while the sound is reflected, reduce the reflection and secondary transmission of the sound, and improve the overall sound insulation effect.

[0033] Rock wool 8 is provided to fill the recessed part on the side of the sound insulation board 6. The protruding part on the side of the sound insulation board 6 is fixedly connected to the fire door panel 5. By using rock wool 8 to fill the outside of the sound insulation board 6, sound can be absorbed on the one hand, and on the other hand, rock wool 8 has a fireproof function, which improves the overall fire resistance of the sound insulation door.

[0034] The sound insulation board 6, rock wool 8, and sound-absorbing cotton 7 are fully enclosed inside the fireproof door panel 5. The top and bottom of the fireproof door panel 5 are equipped with door panel covers. The fireproof door panel 5 isolates the internal structure, reduces the chance of contact with the outside in the event of a fire, and improves the safety factor.

[0035] The door frame body 1 is provided with a protruding edge 2 on the side that is connected to the soundproof door body 9. Springs 3 are located on the protruding edge 2 in sequence. The springs 3 are arranged on both sides along the length of the protruding edge 2. When the springs 3 are extended, the top of the springs 3 is located inside the door frame body 1.

[0036] The buffer cavity 4 is located on the convex edge 2 and arranged along the length direction. The inner side of the buffer cavity 4 abuts against the top of the spring 3, and the edge of the buffer cavity 4 is connected to the inner side of the upper surface edge of the convex edge 2. When the convex edge of the soundproof door body 9 and the door frame body 1 are combined, the soundproof door body 9 squeezes the buffer cavity 4 and is subjected to the force of the spring 3, so that the soundproof door can close slowly, reducing the generation of noise and protecting the door frame body 1 of the soundproof door.

[0037] When the soundproof door body 1 closes, it compresses the spring 3 and the buffer cavity 4 of the door frame body 1. The surface of the soundproof door body 9 is flush with the outer side of the door frame. When the spring 3 is compressed, that is, when the soundproof door presses down on the door frame body 1, the compression height of the spring 3 is just enough to make the outer surface of the soundproof door body 9 flush with the outer surface of the door frame body 1, which makes it easy for the soundproof door body 9 to close.

[0038] When the soundproof door body 9 closes toward the door frame body 1, the spring 3 acts as a buffer for the soundproof door body 9, reducing noise generation and protecting the door frame body 1. The noise inside the factory is gradually reduced through reflection in the soundproof panel 6 and sound-absorbing cotton 7, ultimately achieving the effect of sound insulation.

[0039] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations or modifications.
