Patent No. CN202120631335.9 discloses an indoor partition device, including a supporting frame, which includes vertical poles and horizontal poles; a plurality of slots are arranged linearly and at equal intervals along the height direction on the vertical poles for installing louver-type inserts; the louver-type inserts are perpendicular to the vertical poles and inserted between the two vertical poles; the long sides of the inner blades and the outer blades are butt-jointed at an angle and are both inclined downward, so as to block a large area of the light source; every two inner blades and each cross bar are connected at equal intervals. The two outer blades are arranged in a louver-like manner and have gaps between them to form a gas passage; the edge part is provided with an arc-shaped protrusion. When the external air flows through the surface of the arc-shaped protrusion, the air flow rate at this place becomes larger. According to Bernoulli's principle, the pressure at this place becomes smaller, achieving a ventilation effect; a accommodating cavity is provided inside it, filled with sound-absorbing material to achieve a sound insulation effect; a reflective sticker is provided on the lower side of the inner blade; the light entry caused by the gap between two adjacent louver-shaped inserts is eliminated; although this technical solution can achieve the effects of light isolation, ventilation and sound insulation, its structural strength is low and it cannot serve as a door body. It can only be used indoors and cannot be used on the main door. Therefore, a door body with high strength and sound insulation, light isolation and ventilation is required. Utility Model Content

Ventilation is carried out through hole 1 4 and hole 2 5, and the ventilation gap 7 forms a ventilation effect on the front and back sides of the door body. At the same time, the sound insulation layer 6 is used to silence and absorb sound to achieve a sound insulation effect. There are overlapping parts between the sound insulation layers 6, which avoids or weakens the passage of light, thereby achieving a light isolation effect. At the same time, the inner door panel 2 and the outer door panel 3 are added to the frame 1 to form a door structure. The structural strength is high and it can be applied to the door structure.

[0029] like Figure 3-4 As shown, the sound insulation layer 6 includes a plurality of folded-angle sound insulation strips 61, and adjacent folded-angle sound insulation strips 61 are tightly arranged on the outside to form a serrated structure 62. The sound insulation layers 6 on the adjacent inner door panels 2 and outer door panels 3 are rotationally symmetrically arranged, so that the overlapping parts of the sound insulation layers 6 on the inner door panels 2 and the outer door panels 3 form a folded-line ventilation gap 7, which further improves the light insulation and sound insulation effects while ensuring the ventilation effect. The interior of the folded-angle sound insulation strip 61 is a cavity structure and is filled with sound-absorbing cotton 63. Strip cavities are formed between the folded-angle sound insulation strip 61 and the inner door panels 2 and the outer door panels 3, and the strip cavities are filled with sound insulation cotton strips 64, thereby improving the sound insulation effect.

[0030] like Figure 2 、 5As shown in Figures 8, 9, and 10, ventilation partitions are provided in hole 1 4 and hole 2 5, which can ensure ventilation effect while playing a partition role. The ventilation partitions have two structures, namely a louver structure 8 or a grid structure 9. In terms of structural setting, the louver structure 8 includes a gauze mesh 81, and both sides of the gauze mesh 81 are provided with a number of blades 82 inclined in the same direction. The blades 82 on both sides of the gauze mesh 81 are staggered or symmetrically arranged. The grid structure 9 includes two symmetrically arranged rows of angled pieces 91, and a prismatic hollow column 92 is provided between the two rows of angled pieces 91. The prismatic hollow column 92 is provided between adjacent angled pieces 91, and a ventilation duct is formed between the prismatic hollow column 92 and the angled pieces 91. Specifically, in the position setting of the ventilation partitions, the ventilation partitions on hole one 4 and hole two 5 can be louver structures 8 or grid structures 9; the ventilation partition on hole one 4 can be a louver structure 8, and the ventilation partition on hole two 5 can be a grid structure 9; the ventilation partition on hole one 4 can be a grid structure 9, and the ventilation partition on hole two 5 can be a louver structure 8. In this embodiment, the louver structure 8 is set on hole two 5, and the grid structure 9 is set on hole one 4. During use, the louver structure 8 can isolate mosquitoes and ensure ventilation effect.

[0031] like Figure 2 、 5 As shown, in the overall structural setting, the inner door panel 2 and the outer door panel 3 are fixedly connected to the inner wall of the frame 1, and an integral structure is formed between the inner door panel 2, the outer door panel 3 and the frame 1. The inner wall of the frame 1 is located between the inner door panel 2 and the outer door panel 3 and is fixedly connected to the limiting strip 10. After the door is installed on the door frame, the door can be opened and closed as a whole, and handles 11 are installed on both the inner door panel 2 and the outer door panel 3.

[0032] Example 2

[0033] like Figure 2 、 6 As shown in Figure 7, the structure of the inner door panel 2 and the outer door panel 3 in this embodiment is the same as that in Example 1. The difference is that one side of the inner door panel 2 and the outer door panel 3 are connected to the frame 1 through a hinge rotation, and the other side is elastically clamped with the inner wall of the frame 1. The inner side wall of the frame is located between the inner door panel 2 and the outer door panel 3 and is fixedly connected to the limiting strip 10. The side walls of the inner door panel 2 and the outer door panel 3 are provided with a clamping groove 12, and the inner side wall of the frame 1 is provided with an elastic member 13. After the inner door panel 2 and the outer door panel 3 are closed, the elastic member 13 is clamped with the clamping groove 12. After the door is installed on the door frame, the inner door panel 2 can be opened inward and the outer door panel 3 can be opened outward. After the inner door panel 2 and the outer door panel 3 are opened separately, the ventilation effect can be increased, and a certain degree of sound insulation and light insulation effect can also be achieved. The door as a whole can also be rotated relative to the door frame to open, which increases the diversity of usage functions.
