[0027] Referring to Figures 1-3 The present embodiment provides a concealed hinge door sealing structure, which comprises a door frame 10, a door leaf 100 and a hinge body 200. The door frame 10 is provided with a first mounting groove 111 on the side facing the door leaf 100. The hinge body 200 comprises a first connecting end 210 fixedly connected in the first mounting groove 111 and a second connecting end 220 fixedly connected with the door frame 10. A side edge 112 is arranged between the first mounting groove 111 and the door frame 10 and the gap 11 between the door leaf 100. The side edge 112 is provided with a first sealing strip 310 for sealing the gap 11.

[0028] In this embodiment, when the door leaf 100 is closed, the first sealing strip 310 installed on the side edge 112 of the door frame 10 is pressed by the door leaf 100 to produce elastic deformation, and is tightly filled in the gap 11 between the door frame 10 and the door leaf 100. Since the first sealing strip 310 is directly arranged on the side edge 112 between the first installation groove 111 and the gap 11, the coverage range thereof avoids the installation space of the hinge body 200, and the first sealing strip 310 can provide a sealing structure at the connection of the hinge body 200; the first sealing strip 310 can also completely cover the gap 11 between the door leaf 100 and the door frame 10, without the need for segmented processing of the first sealing strip 310. When the door leaf 100 is closed, the first sealing strip 310 continuously provides radial pressure through elastic deformation, so as to ensure that a continuous sealing interface is formed when the door leaf 100 is closed, effectively blocks the penetration path of air, dust and moisture, and improves the heat preservation and sound insulation effect of the door.

[0029] Preferably, as shown in Figure 1 and Figure 2 , the side edge 112 is provided with a second installation groove 113, and the first sealing strip 310 is connected in the second installation groove 113; the second installation groove 113 can make the installation of the first sealing strip 310 more convenient and accurate, so that the first sealing strip 310 is more firmly installed and avoids falling off. The first sealing strip 310 can be directly embedded or embedded and pasted in the second installation groove 113, thereby improving the durability.

[0030] Preferably, as shown in Figures 1-3 , the second installation groove 113 is T-shaped, and the first sealing strip 310 includes a T-shaped connecting portion 311 embedded in the second installation groove 113; the T-shaped installation groove cooperates with the T-shaped connecting portion 311 of the sealing strip, which not only increases the contact area of the sealing strip and the installation groove, but also makes the sealing strip more flat and stable after installation, so that the sealing strip can be more firmly embedded in the installation groove.

[0031] Preferably, as shown in Figure 1 and Figure 3 , the first sealing strip 310 includes a portion protruding from the second installation groove 113, and the portion is provided with a cavity 312; the cavity 312 can produce elastic deformation when the first sealing strip 310 is pressed, so as to better fit the uneven surface between the door frame 10 and the door leaf 100, effectively fill the small gap 11, further prevent the intrusion of external air, dust, moisture and the like, and improve the sealing effect of the door; the cavity 312 can also better disperse the pressure when the first sealing strip 310 is stressed, thereby reducing deformation and aging caused by long-term pressure.

[0032] Preferably, as shown in Figure 1 and Figure 2As shown in the drawings, the second installation groove 113 penetrates from the top side of the door leaf 100 to the bottom side of the door leaf 100; the second installation groove 113 penetrates from the top side of the door leaf 100 to the bottom side of the door leaf 100, so that the first sealing strip 310 can be continuously installed along the entire height direction of the door leaf 100, forming a complete sealing barrier, ensuring the sealing between the door leaf 100 and the door frame 10 when closed, effectively preventing the intrusion of external air, dust, moisture, etc. from any height position of the door into the room, thereby significantly improving the heat preservation, sound insulation and noise prevention effect of the door.

[0033] Preferably, as shown in the drawings, Figure 1 and Figure 2 the first sealing strip 310 penetrates the second installation groove 113; the first sealing strip 310 can be continuously installed along the entire height direction of the door leaf 100, forming a continuous sealing barrier.

[0034] Preferably, as shown in the drawings, Figure 1 and Figure 2 the first installation groove 111 penetrates from the top side of the door leaf 100 to the bottom side of the door leaf 100, and the hinge body 200 is provided with a second sealing strip 320 installed in the first installation groove 111 above and below; by providing the second sealing strip 320 above and below the hinge body 200, the first installation groove 111 and the second sealing strip 320 form a second sealing structure in addition to the second installation groove 113 and the first sealing strip 310, further preventing the intrusion of external air, dust, moisture, etc., and improving the overall sealing effect of the door.

[0035] Preferably, as shown in the drawings, Figure 1 and Figure 2 the first installation groove 111 and the second installation groove 113 have consistent opening directions; the consistent opening directions make the installation of the sealing strip more accurate and compact; the consistent opening directions of the first installation groove 111 and the second installation groove 113 make the installation process of the second sealing strip 320 and the first sealing strip 310 more simple and efficient.

[0036] Preferably, as shown in the drawings, Figure 1 and Figure 3 the first sealing strip 310 and the second sealing strip 320 are fixedly connected; after the first sealing strip 310 and the second sealing strip 320 are fixedly connected, a continuous sealing barrier can be formed, effectively filling all possible gaps between the door leaf 100 and the door frame 10, further improving the overall sealing effect of the door; the fixedly connected first sealing strip 310 and second sealing strip 320 are more stable after installation, reducing the risk of loosening or falling of the sealing strip due to the opening and closing vibration of the door, and improving the stability of the entire sealing structure.

[0037] Preferably, as shown in the drawings, Figure 1 and Figure 2As shown, the third sealing strip 330 is installed on the door frame 10 to seal the gap 11; when the door is closed, the third sealing strip 330 on the door frame 10 is in contact with the door leaf 100 to form a third sealing structure, thereby further improving the sealing effect of the door.

[0038] Specifically, as shown in Figure 1 and Figure 2 The side of the door leaf 100 facing the door frame 10 is a profile 110, and the first installation groove 111 and the side edge 112 are both arranged on the profile 110.
