Description

Technical Field

[0001] The utility model relates to the field of fireproof doors, in particular to a fireproof door with sound insulation function. Background Art

[0002] A fire door is a door that can meet the requirements of fire resistance stability, integrity and thermal insulation within a certain period of time. It is a fire-resistant partition with a certain fire resistance installed at room entrances, fire compartments, evacuation stairwells, vertical shafts, etc.

[0003] When existing fire doors are used, they usually achieve flame retardancy through the fire-resistant materials inside them. However, in actual use, their overall sound insulation effect is not good and they cannot block the propagation of sound. This makes it easy for people inside to be disturbed by outdoor sounds when they are used as home entrance doors. At the same time, the sound of conversations inside the room can easily be transmitted to the outside, which is not conducive to the privacy of the home. For this reason, we propose fire doors with sound insulation function. Utility Model Content

[0004] In view of the above problems, the utility model provides a fireproof door with sound insulation function, which can solve the problems raised in the above background technology.

[0005] The technical solution of the utility model is:

[0006] The fireproof door with sound insulation function comprises a first frame, the inner side of which is movably connected with a second frame, the inner sides of the first frame and the second frame are both bonded with fireproof boards, and sound insulation mechanisms are bonded between adjacent fireproof boards.

[0007] The working principle of the above technical solution is as follows:

[0008] The fire-resistant board can ensure the overall fire resistance, and the sound insulation mechanism can improve the overall sound insulation effect, so that the whole has good fire resistance and good sound insulation effect, with a simple structure and easy use.

[0009] In a further technical solution, a connecting box is bonded between adjacent sound insulation mechanisms, a first through hole is provided on the top of the connecting box, and a second through hole is provided on the top of both the first frame and the second frame.

[0010] It is convenient to fill sand into the inner side of the connection box through the second through hole and the first through hole, so as to increase the number of sound reflections and the sound insulation effect, and at the same time, it can also improve the overall usage strength and facilitate operation.

[0011] In a further technical solution, a fixing groove is provided at the top of the first frame and the second frame, and a movable cover is provided inside the fixing groove.

[0012] The movable cover plate can be installed on the inner side of the fixed groove, and can be connected and used by riveting technology without welding in the prior art, so the connection can be stably performed and the operation is convenient.

[0013] In a further technical solution, the sound insulation mechanism includes a sound insulation board, and a reflective through groove is opened inside the sound insulation board.

[0014] It is convenient for sound to be reflected back and forth on the inner side of the reflection groove, thereby reducing the energy of sound propagation, thereby achieving the effect of sound insulation and easy operation.

[0015] In a further technical solution, a plurality of fixing through holes are provided on the surface of the sound insulation board.

[0016] The fixing through hole can facilitate the sound to enter the inner side of the reflection groove for reflection, and the operation is convenient.

[0017] The beneficial effects of the utility model are:

[0018] 1. Through the sound insulation mechanism, the number of sound reflections can be increased during use, so as to gradually reduce the energy of sound propagation, thereby achieving a good sound insulation effect. The overall structure is simple and the operation is convenient and quick;

[0019] 2. Through the connection box, the first through hole, the second through hole, the fixed groove and the movable cover, sand can be filled into the interior of the connection box through the first through hole and the second through hole, which can increase the number of sound reflections, improve the sound insulation effect, and also improve the overall use intensity, which is convenient and quick to use.

[0026] The embodiments of the present utility model will be further described below in conjunction with the accompanying drawings.

[0027] Example:

[0028] like Figure 1-Figure 4 As shown, the fireproof door with sound insulation function includes a first frame 1, characterized in that the second frame 2 is movably connected to the inner side of the first frame 1, fire-resistant boards 3 are bonded to the inner sides of the first frame 1 and the second frame 2, and sound insulation mechanisms 4 are bonded between adjacent fire-resistant boards 3. The sound insulation mechanism 4 includes a sound insulation board 10, and a reflective through groove 11 is opened inside the sound insulation board 10, and a plurality of fixing through holes 12 are opened on the surface of the sound insulation board 10.

[0029] The working principle of the above technical solution is as follows:

[0030] During use, when sound is transmitted through the solid and enters the inner side of the sound insulation board 10 through the fixed through hole 12, the sound can be reflected back and forth under the action of the reflective groove 11, thereby reducing the energy of sound propagation, thereby improving the overall sound insulation effect and facilitating operation.

[0031] In another embodiment, if Figure 2 and Figure 3 As shown, a connecting box 5 is bonded between adjacent sound insulation mechanisms 4, a first through hole 6 is provided on the top of the connecting box 5, a second through hole 7 is provided on the top of the first frame 1 and the second frame 2, a fixing groove 8 is provided on the top of the first frame 1 and the second frame 2, and a movable cover plate 9 is provided on the inner side of the fixing groove 8.

[0032] It is convenient to fill sand into the inner side of the connecting box 5 through the first through hole 6 and the second through hole 7. The sand can increase the number of sound reflections, thereby reducing the sound energy and improving the sound insulation effect. At the same time, the movable cover 9 is inserted into the inner side of the fixed groove 8, so that the first frame 1, the second frame 2 and the movable cover 9 are connected by riveting, which can make the whole stably connected and easy to operate.
