Sealing components are provided at the top and bottom of the outer door panel. Each sealing component includes a sealing plate that is slidably connected to the outer door panel. A moving groove is provided on the side of the sealing plate. A first inclined surface is provided on the side of the moving groove near the moving direction of the sealing plate. A push block is slidably connected to the moving groove. A second inclined surface that cooperates with the first inclined surface is provided on the push block. A push rod is provided on the push block. A slot corresponding to the push rod is provided on the side of the outer door panel.

[0005] Furthermore, the outer door panel is provided with a groove for accommodating the sealing plate, and the inner wall of the groove is connected to the sealing plate by a return spring.

[0006] Furthermore, the wall of the movable groove is connected to one end of the movable spring, and the other end of the movable spring is connected to the push block.

[0007] Furthermore, the honeycomb panel is a paper honeycomb panel or an aluminum honeycomb panel, which is fixed to the inner wall of the front door panel with adhesive.

[0008] Furthermore, the inner wall of the front door panel is provided with first positioning posts near the four end points and several second positioning posts in the middle.

[0009] Furthermore, the front door panel is provided with a first sealing protrusion at the top, bottom and outer side, and the top and bottom of the first sealing protrusion are respectively provided with a first adhesive strip and a second adhesive strip.

[0010] Furthermore, a second sealing protrusion extending outward from the edge of the front door panel is used to cover the door frame.

[0011] Due to the adoption of the above technical solutions, the beneficial technical effects of this utility model are as follows: the sealing performance of the security door is effectively improved by setting a sealing component. The sealing component includes a sealing plate. When the security door is closed, the push block connected to the push rod pushes the sealing plate to move outward and abut against the door frame, thereby enhancing the sealing effect of the security door and achieving enhanced sound insulation.

[0021] To more clearly illustrate the technical solution of this utility model, the following description is made in conjunction with the accompanying drawings. Obviously, the drawings described below are only one embodiment of this utility model. For those skilled in the art, other embodiments can be obtained based on these drawings and embodiments without creative effort, and all of them fall within the protection scope of this utility model.

[0022] according to Figure 1-8 As shown, a soundproof structure for a security door includes an inner door panel 1 and an outer door panel 2. A honeycomb panel 3 and a fireproof panel 4 are provided between the inner door panel 1 and the outer door panel 2. Sealing components are provided at the top and bottom of the outer door panel 2. The sealing components include a sealing plate 5 that is slidably connected to the outer door panel 2. A moving groove 6 is provided on the side of the sealing plate 5. A first inclined surface 7 is provided on the side of the moving groove 6 near the moving direction of the sealing plate 5. A push block 8 is provided at the moving groove 6 that is slidably connected to it. A second inclined surface 9 that cooperates with the first inclined surface 7 is provided on the push block 8. A push rod 10 is provided on the push block 8. A slot corresponding to the push rod 10 is provided on the side of the outer door panel 2.

[0023] In the above-mentioned specific technical solution, the sealing performance of the security door is effectively improved by setting a sealing component. The sealing component includes a sealing plate 5. When the security door is closed, the push block 8 connected to the push rod 10 pushes the sealing plate 5 to move outward and abut against the door frame, thereby enhancing the sealing effect of the security door and achieving enhanced sound insulation.

[0024] The outer door panel 2 is provided with a groove 11 for accommodating the sealing plate 5, and the inner wall of the groove 11 is connected to the sealing plate 5 by a return spring 12.

[0025] The wall of the movable groove 6 is connected to one end of the movable spring 13, and the other end of the movable spring 13 is connected to the push block 8.

[0026] In the above specific technical solution, when the security door is opened, taking the sealing assembly installed on the top of the front door panel as an example, the push block 8 moves outward under the action of the moving spring 13, and the sealing plate 5 moves downward under the action of the return spring 12. When the security door is closed, the push rod 10 contacts the door frame, thereby pushing the push rod 10 inward, causing the push block 8 to push the sealing plate 5 upward, and the sealing plate 5 contacts the door frame, thus playing a sealing role and enhancing the sound insulation effect.

[0027] The honeycomb panel 3 is a paper honeycomb panel 3 or an aluminum honeycomb panel 3, which is fixed to the inner wall of the front door panel by adhesive.

[0028] The front door panel has first positioning posts 14 near its four ends on its inner wall, and several second positioning posts 15 in the middle, which facilitates the fixing of the honeycomb panel 3.

[0029] The front door panel is provided with a first sealing protrusion 16 at the top, bottom and outer side. The first sealing protrusion 16 is provided with a first adhesive strip 17 and a second adhesive strip 18 at the top and bottom, respectively, which can improve the sealing performance of the security door and improve the sound insulation effect.

[0030] The second sealing protrusion 19 extends outward from the edge of the front door panel to cover the door frame, further improving the sealing performance of the security door and enhancing sound insulation.

[0031] The above embodiments are merely exemplary embodiments of the present utility model and are not intended to limit the present utility model. The scope of protection of the present utility model is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to the present utility model within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of the present utility model.
