[0030] like Figures 1-13 As shown, this utility model discloses an aluminum-steel composite steel concealed door, comprising a door body 1 for installation in a doorway 400 of a building wall 300. The door body 1 includes an aluminum alloy door frame 2 and decorative panels 3 disposed at the front and rear ends of the aluminum alloy door frame. The decorative panels serve a decorative purpose and can be replaced with different types and materials as needed. The aluminum alloy door frame 2 includes a pair of left and right vertical door profiles 6. Horizontal door profiles 7 are provided between the upper and lower ends of the pair of vertical door profiles 6. The left and right ends of the horizontal door profiles 6 are respectively spliced ​​with the pair of vertical door profiles 7, and the splicing points are connected by connectors. The horizontal door profiles and vertical door profiles of the aluminum alloy door frame are assembled by splicing and connected by connectors, eliminating the need for welding and making the overall structure less prone to deformation during processing and installation.

[0031] In this embodiment, the decorative panel 3 is made of the same material as the wall panel 600 on the front side of the building wall 300, which improves the concealment effect of the hidden door.

[0032] In this embodiment, the left and right ends of the horizontal door profile 7 are symmetrically provided with first splicing slopes 8, and the upper and lower ends of the vertical door profile 6 are symmetrically provided with second splicing slopes 9. The first splicing slopes 8 and the second splicing slopes 9 are parallel, and the inclination angle of the splicing slopes can be 45 degrees. The upper and lower ends of the vertical door profile 6 are spliced ​​together with the first splicing slopes 8 of the horizontal door profile 7 through the second splicing slopes 9. The horizontal door profile and the vertical door profile are connected at the splicing point of the slopes by a connector, and the connector is located inside the splicing point.

[0033] In this embodiment, the first splicing inclined surface 8 is provided with two horizontal slots 10 distributed front to back, and the left and right ends of the front side of the horizontal door profile 7 are provided with several first connecting holes 11 communicating with the horizontal slots 10; the second splicing inclined surface 9 is provided with two vertical slots 12 distributed front to back, and the upper and lower ends of the front side of the vertical door profile 6 are provided with several second connecting holes 13 communicating with the vertical slots 12; the connector includes two right-angled connecting blocks 14 distributed front to back, the horizontal side of the connecting block 14 is inserted into the horizontal slot 10, and is locked together with the horizontal door profile 7 by a first fastener 15 (e.g., a bolt or screw) passing through the first connecting hole 11; the vertical side of the connecting block 14 is inserted into the vertical slot 12, and is locked together with the vertical door profile 6 by a second fastener 16 (e.g., a bolt or screw) passing through the second connecting hole 13. The aluminum alloy door frame is constructed by splicing aluminum alloy door frames, and the vertical and horizontal door profiles are connected by internal connecting blocks, which facilitates assembly and provides excellent concealment of the joints, reducing their visibility. At the same time, the aluminum alloy door frame has high overall structural strength and is not easily deformed.

[0034] In this embodiment, to improve the structural strength of the aluminum alloy door frame, a number of horizontal reinforcing bars 17 are evenly distributed from top to bottom between a pair of vertical door profiles 6. Preferably, the horizontal reinforcing bars 17 are made of composite steel.

[0035] In this embodiment, the bottom of the horizontal door profile between the lower ends of a pair of vertical door profiles is integrally formed with an installation groove 4, and a door bottom seal 5 is provided in the installation groove 4. The traditional method of installing the door bottom seal is to cut a groove at the bottom of the door panel. In this embodiment, the installation groove is directly integrally formed into the horizontal door profile between the lower ends of a pair of vertical door profiles. During installation, the door bottom seal is directly inserted into the installation groove without the need for additional grooving, which improves the convenience and efficiency of installation.

[0036] In this embodiment, as Figure 6-11 As shown, the room also includes a door frame 500 installed in the doorway 400 of the building wall 300. A magnetic sealing element 90 is provided at the door gap 18 between the door body and the door frame. The magnetic sealing element 90 includes a first magnetic sealing strip 50 and a second magnetic sealing strip 60 with opposite magnetic properties. The first magnetic sealing strip 50 is installed in the aluminum alloy frame 2, and the second magnetic sealing strip 60 is installed in the door frame 500. When the door is closed, the first magnetic sealing strip 50 and the second magnetic sealing strip 60 are oppositely distributed and magnetically attracted to each other. By installing a magnetic sealing element at the door gap, the first magnetic sealing strip and the second magnetic sealing strip are oppositely distributed and magnetically attracted to each other when the door is closed, effectively improving the sealing effect at the door gap, thereby achieving a good sound insulation effect.

[0037] In this embodiment, for sealing the door gaps between the left and right ends of the concealed door and the left and right ends of the door frame, specifically: Each of the opposite ends of the front ends of a pair of vertical door profiles 6 is provided with a horizontal V-shaped first sealing mounting portion 140. Each of the first sealing mounting portions 140 at the front ends of the pair of vertical door profiles 6 is provided with a vertically extending first snap-fit ​​groove 150. The first snap-fit ​​grooves at the front ends of the pair of vertical door profiles are distributed on the left and right sides of the decorative panel. The first magnetic sealing strip 50 is embedded in the first snap-fit ​​groove 150. The door frame 500 includes a pair of door frame profiles 13 distributed on the left and right. Each of the adjacent ends of the front ends of the pair of door frame profiles 130 is provided with a horizontal L-shaped second sealing mounting portion 160. Each of the second sealing mounting portions 160 on an adjacent side of the front ends of the pair of door frame profiles 130 is provided with a second snap-fit ​​groove 170. The second magnetic sealing strip 60 is embedded in the second snap-fit ​​groove 170. When the door is closed, the positions of the first and second snap-fit ​​grooves on the same side correspond.

[0038] In this embodiment, one end of the first magnetic sealing strip 50 extends out of the first latching groove 150 and is provided with a first magnetic inclined surface 180, while the other end of the first magnetic sealing strip 50 is embedded in the first latching groove; one end of the second magnetic sealing strip 60 extends out of the second latching groove 170 and is provided with a second magnetic inclined surface 190, while the other end of the second magnetic sealing strip is embedded in the second latching groove. When the door is closed, the second magnetic inclined surface 190 is parallel to the first magnetic inclined surface 180 and magnetically engages with it. Preferably, the inclination angle of both the first and second magnetic inclined surfaces is 30 degrees.

[0039] In this embodiment, the first latching groove 150 has a first latching arm 200 extending vertically on both opposite sides; the first magnetic sealing strip 50 has a first limiting groove 210 cooperating with the first latching arm 200 on both sides; the second latching groove 170 has a second latching arm 220 extending vertically on both opposite sides; and the second magnetic sealing strip 60 has a second limiting groove 230 cooperating with the second latching arm 220 on both sides.

[0040] It should be noted that this embodiment is for sealing the gaps between the left and right ends of the concealed door and the left and right ends of the door frame. For sealing the gap between the top of the door body and the door frame, magnetic sealing components can also be used (i.e., forming a seal for the top, left, and right door gaps). The sealing structure is the same as the sealing method for the gaps on the left and right sides of the door body, and will not be repeated here.

[0041] In this embodiment, the first magnetic sealing strip 50 includes a first soft magnetic strip, the outer side of which is covered with a rigid covering layer; the second magnetic sealing strip 60 includes a second soft magnetic strip, the outer side of which is covered with a flexible covering layer. The first magnetic sealing strip and the second magnetic sealing strip are respectively in a rigid and flexible state, which not only improves the tightness of their fit, but also achieves silent closing.
