Description

Technical Field

[0001] The utility model relates to the technical field of building material decoration products, in particular to a door structure, especially an armored door. Background Art

[0002] Armored doors are widely used in business, commercial, and residential settings due to their high structural strength and high-end aesthetics. To improve the thermal insulation and sound insulation properties of the product and enhance its sealing properties, sealing strips are often used to seal gaps. However, armored doors currently on the market generally suffer from the following shortcomings: First, their airtightness, thermal insulation, and sound insulation are insufficient. This is primarily because there is typically only one sealing strip on the hinge side of the door leaf. When exposed hinges are used, the sealing strip at the hinge needs to be disconnected, which compromises the integrity of the sealing strip. If the sealing strip on the door frame is also ineffective, this will affect the sealing of the entire door. Second, the sealing strip is generally just a simple solid or hollow strip structure with poor deformation resistance, which affects the sealing performance. Third, the general use of only one or two hinges is limited in appearance and function, and cannot meet the needs of personalized customization. In addition, the edge banding of the door leaf is complex and thick. Utility Model Content

DETAILED DESCRIPTION

[0020] In this embodiment, refer to Figure 1-Figure 7 The armored door with improved sealing structure includes a door leaf 1 and a door frame 2. The door leaf 1 is assembled with the door frame 2 to form a rotatable structure through a hinge; an edge banding strip 6 is provided on the side edge of the door leaf 1, and a sealing strip is provided between the door frame 2 and the door leaf 1; the sealing strip includes a first sealing strip 3, a second sealing strip 4 and a third sealing strip 5. A first sealing groove 61 is provided near the bottom surface of the edge banding strip 6, and the first sealing strip 3 is installed in the first sealing groove 61; a second sealing groove 62 is provided in the middle position of the edge banding strip 6, and the second sealing strip 4 is installed in the second sealing groove 62; on the door frame 2 A third sealing groove 21 is provided at a position opposite to the front edge of the door leaf 1, and the third sealing strip 5 is installed in the third sealing groove 21; a first abutting portion 23 and a second abutting portion 22 in a stepped shape are respectively provided at positions of the door frame 2 opposite to the first sealing strip 3 and the second sealing strip 4. After the door leaf 1 is closed, the first sealing strip 3 is pressed against the first abutting portion 23, the second sealing strip 4 is pressed against the second abutting portion 22, and the third sealing strip 5 is pressed against the front edge of the door leaf 1, thus forming a three-sealing structure. Even if the sealing strip at the hinge needs to be disconnected, a good sealing effect can still be maintained.

[0021] The main bodies of the first, second, and third sealing strips 3, 4, and 5 are all hollow structures. A first sealing tongue edge 31 extends forward from the front of the first sealing strip 3, a second sealing tongue edge 41 extends forward from the front of the second sealing strip 4, and a third sealing tongue edge 51 extends forward from the front of the third sealing strip 5. When the door leaf 1 is closed, the first sealing tongue edge 31 abuts against the first abutting portion 23, the second sealing tongue edge 41 abuts against the second abutting portion 22, and the third sealing tongue edge 51 abuts against the front edge of the door leaf 1. This elastic contraction of the hollow parts of the sealing strip bodies in conjunction with the elastic contraction of the sealing tongue edges can further enhance sealing performance.

[0022] The first sealing tongue edge 31 , the second sealing tongue edge 41 and the third sealing tongue edge 51 all have an outer surface with an arc-shaped structure, and each sealing strip is made of EPDM rubber strip.

[0023] The edge banding strip 6 is a double-sided narrow frame edge banding strip. After it is fixed to the side of the door leaf 1, the narrow frames on both sides respectively cover the front edge and the back edge of the door leaf 1. The covering width is 5-6mm, such as 5.5mm, achieving an extremely narrow edge effect.

[0024] The back of the edge banding 6 features a slot with a width of 6-9mm, for example, 6.6mm. A decorative panel 7, suitable for thicknesses from 1-8mm, is positioned on the back of the door leaf. When the thickness of the exterior panel 7 exceeds 2mm, it remains flush with the edge banding 6, creating a nearly seamless effect and a seamless, harmonious whole. Combined with one of four minimalist door frame styles, the result is a minimalist visual experience and a sense of relaxation.

[0025] The total thickness of the entire door leaf 1 is not less than 90mm, which makes the thermal insulation performance of the door leaf 1 better. A lock groove 64 with a notch width greater than 35mm, such as 35.2mm, is provided on the movable side edge of the door leaf, so that lock bodies with panel widths of 24mm, 30mm, and 35mm are all available.

[0026] The hinge can be a light concealed hinge 81 (such as Figure 3 As shown), weighted hidden hinge 82 (as Figure 4 As shown), the heaven and earth axis hinge 83 (as shown Figure 5 ) or 3D hinge 84 (as shown Figure 6 As shown), or with a hinge 85 (as shown Figure 7 Assemble the door leaf 1 in a concealed manner (as shown).

[0027] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and should not limit the scope of implementation of the present application. That is, all equivalent changes and modifications made within the scope of the present application should still fall within the scope of the present invention.
