[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] Example 1

[0027] like Figure 1-3As shown, the utility model provides a sound insulation structure inside a door body, including a door frame 1, wherein the inner wall of the door frame 1 is respectively provided with two door panels 2, which are arranged to be opened and closed, and the door panels 2 are composed of a hinge shaft 21 and a sound insulation board 22, and the sound insulation board 22 is hinged to one side of the inner wall of the door frame 1 through the hinge shaft 21, and the inner wall of the door frame 1 is respectively provided with bonding plates 24 for enhancing sealing performance at the front and back positions between the two door panels 2, and the two bonding plates 24 are staggered and fixedly connected with the door panels 2 at the corresponding positions, and by setting the conventional single leaf into two door panels 2, the doors on both sides can be reduced. The weight borne at the hinge of the board 2 can avoid the problem that the hinge of the door panel 2 is easy to deform and the service life is shortened due to the thickness of the door panel 2. A bonding plate 24 is set between the door panels 2 for sealing, which can avoid the gap between the door panels 2 when they are closed to affect the sound insulation effect. The two sound insulation panels 22 are set in an arc shape on the sides corresponding to each other to avoid the problem that the sound insulation panels 22 will collide with each other when closed. A rubber strip is fixedly connected to the side of the bonding plate 24 close to the sound insulation panel 22 to increase the sealing, and the inside of the sound insulation panel 22 is filled with sound insulation cotton to enhance the sound insulation effect.

[0028] In this embodiment, by configuring a conventional single door panel 2 as two door panels 2, the weight borne at the hinges of the door panels 2 on both sides can be reduced, thereby avoiding the problem of deformation of the hinges of the door panels 2 and shortening their service life due to the thickness of the door panels 2. By configuring a fitting plate 24 between the door panels 2 for sealing, it is possible to avoid the generation of gaps between the door panels 2 when they are closed, which would affect the sound insulation effect.

[0029] Example 2

[0030] like Figure 1-3 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the sound insulation board 22 is close to the inner wall of the door frame 1 and the position near the front and back sides are respectively provided with sealing components 23, and the sealing components 23 are composed of a slide groove 231, a slide plate 232, and a spring 233. The two slide grooves 231 are respectively opened at the positions near the front and back sides of the inner wall of the door frame 1 of the sound insulation board 22, and the two slide plates 232 are respectively slidably connected to the inner walls of the two slide grooves 231, and the slide plates 232 are respectively connected to the inner walls of the door frame 1. One side of the inner wall is fitted, and the slide plate 232 is set in an arc position near the inner wall of the door frame 1. Two rows of springs 233 are respectively fixedly connected to the positions between the inner wall of the slide groove 231 and the slide plate 232. By setting the slide plate 232 at the hinge of the sound insulation board 22 and slidingly connected to the inner wall of the slide groove 231 through the tension support of the spring 233, when the door panel 2 is closed, the tension of the spring 233 pushes the slide plate 232 against the inner wall of the door frame 1, so as to enhance the sealing and avoid affecting the sound insulation effect.

[0031] In this embodiment, a slide plate 232 is provided at the hinge of the sound insulation board 22 and is slidably connected to the inner wall of the slide groove 231 through the tension support of the spring 233, so that when the door panel 2 is closed, the tension of the spring 233 pushes the slide plate 232 against the inner wall of the door frame 1, so as to enhance the sealing and avoid affecting the sound insulation effect.

[0032] The following is a detailed description of the working principle of the internal sound insulation structure of the door body.

[0033] like Figure 1-3 As shown, when in use, by configuring a conventional single leaf into two door panels 2, the weight borne at the hinges of the door panels 2 on both sides can be reduced, thereby avoiding the problem that the hinges of the door panels 2 are easily deformed and the service life is shortened due to the thickness of the door panels 2. By arranging a fitting plate 24 between the door panels 2 for sealing, it is possible to avoid that a gap is generated between the door panels 2 when they are closed, which affects the sound insulation effect. By arranging a slide plate 232 at the hinge of the sound insulation plate 22, which is slidably connected to the inner wall of the slide groove 231 and supported by the tension of the spring 233, when the door panel 2 is closed, the tension of the spring 233 pushes the slide plate 232 against the inner wall of the door frame 1, so as to enhance the sealing and avoid affecting the sound insulation effect.
