[0023] In addition, in the description of the present application, "a plurality of" means at least two, for example, two, three, etc., unless otherwise specifically limited.

[0024] In the present application, unless otherwise specifically defined and limited, the terms "set", "sleeve", "connect", "penetrate", "plug" and the like should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrated; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the internal communication of two elements or the interaction relationship between two elements, unless otherwise specifically limited. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0025] Referring to Figure 1 and Figure 2 A household entrance door with strong self-sealing performance, comprising an outer door panel 1, an inner door panel 2 and a door panel frame 3, the outer door panel 1 and the inner door panel 2 are fixed to the front and rear ends of the door panel frame 3 respectively, the length and width of the outer door panel 1 are greater than those of the door panel frame 3, an active frame 4 is movably arranged on the door panel frame 3, a sealing component 5 is installed between the outer door panel 1 and the door panel frame 3, and when the door is closed, the active frame 4 extrudes the sealing component 5, so that the sealing component 5 forms a self-sealing between the door frame and the door panel frame 3.

[0026] In the above technical solution, the outer door panel 1 is limited by the door frame when the door is closed, and the active frame 4 can translate along the door panel frame 3, when the door is closed, the active frame 4 first contacts the stepped surface of the door frame, and as the door continues to close, the active frame 4 is displaced and extrudes the sealing component 5, so that the sealing component 5 expands and forms a self-sealing with the door frame.

[0027] According to the needs of the customer, the door panel frame 3 can be filled with sound insulation cotton to enhance sound insulation.

[0028] Referring to Figure 3 As shown in the figure, the door frame 8 is sealed by the original sealing ring 88.

[0029] Referring to Figure 2 As shown in the figure, the upper and lower end faces of the door panel frame 3 are provided with a sliding groove 31, which penetrates towards the direction of the outer door panel 1. The inner side of the movable frame 4 is provided with a sliding block 41 that slides along the sliding groove 31. The sealing component 5 is applied between the outer door panel 1 and the movable frame 4.

[0030] In the above technical solution, the cooperation of the sliding groove 31 and the sliding block 41 can realize the sliding guidance of the movable frame 4.

[0031] During installation, first, the movable frame 4 is assembled with the door panel frame 3, then the sealing component 5 is sleeved outside the door panel frame 3, and then the door panel frame 3 is fixed with the outer door panel 1.

[0032] Referring to Figure 3 and Figure 4 As shown in the figure, the sealing component 5 includes a sealing strip 501, the outer side of which is injection molded to form an outwardly convex arc-shaped sealing part 502. The sealing strip 501 has a sealing frame 503, the size of which is consistent with the size of the outer door panel 1 and is partially embedded in the outer door panel 1. The movable frame 4 acts on the side of the sealing strip 501 away from the outer door panel 1.

[0033] In the above technical solution, the sealing strip 501 is extruded by the movable frame 4, so that it is elastically deformed and sealed between the door panel frame 3 and the door frame.

[0034] Referring to Figure 4 As shown in the figure, the inside of the sealing strip 501 is injection molded to form a cavity 511, and the inside of the cavity 511 is injection molded to form an open slot 512.

[0035] The cavity 511 is provided to facilitate the elastic deformation of the sealing strip 501.

[0036] Referring to Figure 4 As shown in the figure, a convex column 513 is correspondingly provided at the inner wall of both sides of the cavity 511. The corresponding convex columns 513 are provided in multiple groups, and a spring 514 is sleeved between each group of corresponding convex columns 513.

[0037] When the movable frame 4 is displaced to the limit position away from the outer door panel 1, the spring 514 is in a released state, and both ends of the spring 514 are sleeved outside the convex column 513.

[0038] The sealing strip 501 is made of elastic rubber.

[0039] In the above technical solution, the spring 514 is arranged, and when the door is opened, the spring 514 is used to apply a counterforce by virtue of elasticity, so that the sealing strip 501 is more easily restored elastically when the door lock is unlocked, and the door is more easily opened.

[0040] The disadvantage is that when the door is closed, a greater pulling force needs to be applied to compress the spring 514, and whether to add the spring 514 is selected according to personal preference of the user.
