In view of the above-mentioned first class of noise, it is often necessary to improve the structure of the aircraft and to add sound insulation layers, etc. Meanwhile, the working environment of the airplane is considered, and the sound insulation layer is required to be ensured to have a good heat insulation effect. In the prior art, the heat and sound insulation layers are generally arranged among the multilayer equipment of the airplane. When designing the heat and sound insulation layer, the specification and the size of the corresponding heat and sound insulation layer are generally determined by the size of the side window. However, in the actual processing process, in order to avoid the breakage of the heat and sound insulation layer and the leakage of the content, the functional material needs to be packaged, the sealing edge formed by the packaging treatment needs to be at least 20mm away from the edge of the content, and at the moment, the sealing edge interferes with the porthole part, so that the installation of the heat and sound insulation layer in the porthole area is difficult.

The traditional processing mode is that aiming at the edge sealing structure, the filling position of the content is adjusted, so that the filling range of the content is retreated by at least 15mm, and the normal installation of the porthole is not influenced by the edge sealing formed after processing.

The utility model provides a banding structure for adiabatic sound insulation layer, include: the edge sealing body 1 and the slit 2 formed on the edge sealing body 1, the edge sealing body 1 is connected end to end and forms a hollow structure 11, and the slit 2 is formed at the inner side edge of the edge sealing body 1 and points to the outer side edge of the edge sealing body 1.

Because the slit 2 is designed on the edge sealing body 1, when the edge sealing body 1 is installed, the edge sealing body 1 can be turned over through the slit 2, so that the structure of the porthole is better adapted, and the installation difficulty of the porthole area is reduced; in addition, the slit 2 structure can increase the installation space of the corresponding porthole without adjusting the size of the heat and sound insulation layer and the width of the edge sealing body 1, so that the heat and sound insulation layer and the porthole can be installed in a better matching manner.

The slit 2 may be formed by cutting.

In actual use, the larger the number of slits 2, the less interference between the heat and sound insulating layer and the porthole structure will occur.

However, the larger the number of slits 2, the better. The inner edge of the sealing edge body 1 can be divided into a plurality of foldable structures by the slits 2, and the structures can avoid the porthole structure in a folding mode. Along with the increase of the number of the slits 2, the number of the turnover structures is gradually increased, the more structures need to be adjusted during installation, and the installation efficiency is slowed. In addition, the greater the number of slits 2, the more difficult the processing of the edge sealing structure becomes, resulting in an increase in the processing cost thereof.

Therefore, in general, the number of slits 2 is not less than four.

In actual processing, the number of slits 2 needs to be adjusted according to the specific shape and size of the hollow structure 11.

The shape of the inner edge of the trim body 1 is influenced by the shape of the hollow structure 11, i.e. the porthole portion. As an alternative embodiment, the inner edge of the sealing body 1 is formed by a curvilinear and/or linear section.

Specifically, when the edge sealing body 1 is formed by splicing a curved section and a straight section, at least two slits 2 are arranged on the curved section, and the two slits 2 are positioned on two sides of the curved section; in the same way, the two sides of the straight line section are also respectively provided with a slit 2 structure.

When the slit 2 is arranged at the intersection point or the position near the intersection point of different straight lines or curve segments, a better avoiding effect can be realized.

As an alternative embodiment, the hollow structure 11 formed inside the edge sealing body 1 is an ellipse or a regular polygon.

As shown in fig. 1, the hollow structure 11 in the edge sealing body 1 is similar to a rounded rectangle, and two slits 2 are arranged in four directions, namely, up, down, left, and right, of the inner edge of the edge sealing body 1. Alternatively, the hollow structure 11 in the sealing edge body 1 in the figure can also be deformed into an elliptical structure, and the number of the slits 2 is not changed, and the specific distribution positions can be adaptively adjusted according to needs.

Alternatively, as shown in fig. 2, in this case, the hollow structure 11 in the edge sealing body 1 is a regular hexagon structure, and in this case, one slit 2 is provided at a contact point of any two straight lines at the inner edge of the edge sealing body 1.

In order to avoid the damage at the slit 2, as an alternative embodiment, a crack stop hole 3 is provided at one end of the slit 2, which points to the outer edge of the edge sealing body 1, and the crack stop hole 3 can prevent the edge sealing body 1 from being pulled by an external force to crack from the end of the slit 2, thereby effectively protecting the edge sealing body 1 and the core body located in the direction of the outer edge of the edge sealing body 1, and preventing the core body from being exposed.

It should be noted that there is a gap between the side edge of the crack stop hole 3 and the outer edge of the sealing body 1.

In general, the crack stopper hole 3 has a circular structure and a diameter of not more than 6mm.

The utility model also provides a thermal insulation sound insulation layer, including above-mentioned arbitrary thermally insulated sound insulation layer with banding structure, still include the core, the core is arranged in the outside edge direction of banding body 1.

The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present invention, and all should be covered within the protection scope of the present invention.
