Detailed Description

The following description is only for the preferred embodiment of the present invention, and the protection scope of the present invention is not limited thereby, the present invention will be further explained with reference to the drawings and the embodiments.

Example 1, see FIGS. 1-2: the utility model relates to a noise reduction door structure, which comprises a front door panel 1, a rear door panel 2, a sound absorption coiled material 3, an upper receiving roller 4 and a lower receiving roller 5, wherein the front door panel 1 and the rear door panel 2 are fixedly attached, the attaching surfaces of the front door panel 1 and the rear door panel 2 are respectively provided with a groove-shaped recess to form a sound insulation cavity 6, the sound insulation cavity 6 is a flat cuboid structure, the upper end and the lower end of the sound insulation cavity 6 are both provided with openings communicated with the rear door panel 2, the upper receiving roller 4 and the lower receiving roller 5 are rotatably arranged at the upper end and the lower end of the rear door panel 2, the upper receiving roller 4 and the lower receiving roller 5 are both provided with a rotary damper 7 for improving the rotary damping thereof, particularly, the rotary damper 7 is a damper, the shell of the rotary damper 7 is relatively fixed with the position of the rear door panel 2, and the central rotary part is fixed with the roller shaft of the upper receiving roller 4 or the lower receiving roller 5, therefore, a certain damping degree can be provided for the rotation of the upper receiving roller 4 and the lower receiving roller 5, and the damping force is greater than the weight of the sound-absorbing coiled material 3, so that the position of the sound-absorbing coiled material 3 is conveniently fixed;

on accomodate roller 4 and the one end of accomodating roller 5 down be fixed with handle 8, inhale sound coiled material 3 and include two sections sound absorption fiber cloth 9 and film cloth 10 of concatenation in proper order, inhale sound fiber cloth 9 and make for many empty fibre, its effective absorption ambient noise, and inhale sound coiled material 3 with sound insulation chamber 6 wait wide, and length does sound insulation chamber 6 length's twice, sound absorption fiber cloth 9 and film cloth 10 are isometric, inhale sound coiled material 3's film cloth 10 fixed connection on accomodate roller 4, inhale and accomodate roller 5 under the sound fiber cloth 9 fixed connection, just it is from last to running through down to inhale sound coiled material 3 sound insulation chamber 6.

An upper shell 11 and a lower shell 12 are respectively and fixedly arranged at the upper opening and the lower opening of the rear door panel 2, the upper accommodating roller 4 and the lower accommodating roller 5 are respectively and rotatably arranged in the upper shell 11 and the lower shell 12, and one end provided with a handle 8 extends out of the upper shell 11 or out of the lower shell 12.

When the device is used specifically, a user rotates the handle 8 to rotate the upper receiving roller 4, so that the film cloth 10 is wound on the roller shaft of the upper receiving roller 4, and the sound-absorbing fiber cloth 9 completely covers the sound-insulating cavity 6, and the best noise reduction and sound insulation effects are achieved; the lower receiving roller 5 can be rotated to roll the sound-absorbing fiber cloth 9 onto the roller shaft of the lower receiving roller 5, and the film cloth 10 completely covers the sound insulation cavity 6, so that the noise reduction effect is poor, but nearby environmental sounds can be heard, and due to the action of the rotary damper 7, the upper receiving roller 4 and the lower receiving roller 5 cannot rotate randomly, and the interior of the door body is stable.

The present invention and the embodiments thereof have been described above, but the description is not limited thereto, and the embodiment shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. In summary, those skilled in the art should understand that they should not be limited to the embodiments described above, and that they can design the similar structure and embodiments without departing from the spirit of the invention.
