Detailed Description

The present invention will be described in further detail with reference to examples, but the embodiments of the present invention are not limited thereto.

Examples

As shown in fig. 1, the soundproof door assembly of the present invention includes a door frame 1, and a door leaf 2 hinged and rotatable to the door frame 1. Like traditional soundproof door, the utility model discloses a door leaf 2 and door frame 1 are articulated through the hinge for door leaf 2 can open and close.

Specifically, as shown in fig. 2, the door frame 1 is provided with a boss 5, and both sides of the door leaf 2 are provided with convex edges 4 which are matched with the boss 5, and the structure is shown in fig. 3. As shown in fig. 4, protruding edge 4 and 5 lids of boss close when door leaf 2 closes, and the medial surface of door leaf 2 closes with the lateral surface lid of door frame promptly, and protruding surface along 4 closes with the surperficial lid of boss 5, makes door leaf 2 and door frame 1 form hyperbolic chi seam structure by above-mentioned structure, realizes the laminating of compacting of door leaf door frame, improves syllable-dividing effect.

In order to further improve the sound insulation effect, as shown in fig. 5, a first sound insulation plate 21, a sound absorbing plate 23, and a second sound insulation plate 24 are provided inside the door leaf 2 in this order from outside to inside, that is, the first sound insulation plate 21, the sound absorbing plate 23, and the second sound insulation plate 24 are provided in this order from outside to inside. The sound-absorbing panel 23 and the second sound-absorbing panel 24 are attached to each other, and the sound-insulating chamber 22 is formed between the first sound-absorbing panel 21 and the sound-absorbing panel 23.

When the outdoor noise passes through the door 2, the first soundproof panel 21 insulates sound, and the attenuated sound enters the soundproof chamber 22, and the first soundproof panel 21 and the soundproof chamber 22 have different air tightness, so that the sound is attenuated again in the soundproof chamber 22. After sound insulation twice, sound waves are absorbed by the sound-absorbing plate 23 and finally sound insulation is carried out by the second sound-insulating plate 24, so that the noise entering the room is weakened to a great extent. The first baffle plate 21 and the second baffle plate 24 are damping baffle plates.

Further, as shown in fig. 6, the sound-absorbing plate 23 is formed with a plurality of projections 231 on the side facing the sound-insulating chamber 22, i.e., the projections face the outside. Two adjacent protrusions 231 are connected through circular arcs 232, and the protrusions 231 are distributed in an array mode, so that alternately distributed wave crests and wave troughs are formed on the sound-absorbing plate 23, noise with different frequencies can be absorbed through the structure, the absorption range of the noise frequency is enlarged, and a better noise absorption effect is achieved.

As another preferable scheme, each protrusion 231 is provided with a sound absorbing hole 233, the sound absorbing hole 233 penetrates through the protrusions 231, and the sound absorbing holes 233 of each protrusion 231 are communicated with each other, as shown in fig. 6. When sound waves are incident into the sound-absorbing hole 233, air vibration in the gap may be caused; due to the viscous resistance of the air, the air rubs against the walls of the hole, thereby absorbing and dissipating a portion of the sound energy. The sound-absorbing holes 233 are communicated with each other, so that noise can be transmitted in the sound-absorbing holes 233 at a maximum distance, and the maximum attenuation can be achieved, thereby achieving a better sound-absorbing effect.

As another preferred scheme, as shown in fig. 4, a sealing strip 3 is disposed between the door frame 1 and the door leaf 2, i.e. the sealing strip 3 is adhered to the surface of both the door frame 1 and the boss 5, and the sealing strip 3 can seal the gap between the door leaf 2 and the door frame 1 when the door leaf 2 is closed.

Specifically, as shown in fig. 7, the sealing strip 3 includes a sealing body 31, a plurality of small through holes 33 penetrating the sealing body 31 along the length direction of the sealing body 31, and a large through hole 34 disposed inside the sealing body 31 and located below the small through holes 33; the small through holes 33 and the large through holes 34 are arranged in a staggered manner. The number of the small through holes 33 and the large through holes 34 may be set according to the size of the sealing body 31, and in the present embodiment, the number of the small through holes 33 is set to 3, and the number of the large through holes 34 is set to 4.

Furthermore, extension parts 32 are disposed on two sides of the sealing body 31, and a groove 35 is disposed at a lower end of the extension part 32. When in use, one side of the extension part with the groove 35 is attached to the surface of the door frame 1 or the boss 5. Through crisscross little through-hole 33 and the big through-hole 34 that sets up for the sealing strip can be by a wide margin block, separate the receipts with the noise, and then improve soundproof effect of soundproof door.

As described above, the utility model discloses alright fine realization.
