Description

Technical Field

[0001] This utility model relates to a sound insulation and sealing technology for an all-aluminum alloy door, and particularly to an all-aluminum alloy door with magnetic sealing. Background Technology

[0002] All-aluminum alloy doors typically refer to door components composed of aluminum alloy door frames, aluminum alloy door casings, and aluminum alloy panels. In other words, the entire door frame, casing, and door leaf are primarily made of aluminum alloy. Aluminum alloy doors are widely used because they are more than four times stronger and more durable than traditional wooden doors, are environmentally friendly (formaldehyde-free), impact-resistant, easy to maintain, waterproof, and insect-proof, and can improve the interior and overall room environment. To ensure the sound insulation and sealing performance of all-aluminum alloy doors, foam strips or felt strips are usually attached to the sides of the door stop. When the door is closed, the front edge of the door leaf and the side of the door stop create a seal against the foam or felt strips, thus achieving sound insulation. The doorstop refers to the step formed by the door frame from the side with the larger internal volume to the side with the smaller internal volume (because this step obstructs the door when it is closed from the side with the larger internal volume, it is called a doorstop); the side of the doorstop usually refers to the flat surface formed by the doorstop on the side with the larger internal volume, where the side of the doorstop faces the front edge of the door when the door is closed. Since the sponge strips or felt strips are pasted onto the side of the doorstop, prolonged compression and environmental climate effects can cause the sponge strips or felt strips to deform, lose elasticity, or fall off, thus losing their sound insulation and sealing function.

[0003] Obviously, existing methods for sound insulation and sealing of door gaps in all-aluminum alloy doors have problems such as the sealing sponge strips or felt strips potentially deforming, losing elasticity, or falling off, thus losing their sound insulation and sealing effect. Summary of the Invention

The door frame includes door leaf posts 2-1, door leaf edge banding 2-2, and door panels 2-4. The door leaf posts are rectangular aluminum alloy profiles, with two horizontal and two vertical posts forming the door leaf frame. The front and rear sides of the door leaf posts have clips for inserting the door panels, and the outer side has slots for fastening the door leaf edge banding. The door leaf edge banding is a bent aluminum alloy profile that fastens into the slots of the door leaf posts, and a protrusion with an equilateral triangular cross-section is provided at the position corresponding to the door leaf post stop. The door panels are aluminum honeycomb panels, consisting of two pieces, respectively inserted into the front and rear of the door leaf posts. The sealing and soundproofing structure is located within the side buckle; it is positioned in the gap between the doorpost's stop and the protrusion on the door leaf's edge, including magnetic strips 1-3 inclined at 45 degrees on the inner side of the doorpost's stop and magnetic strips 2-3 on the inclined surface of the triangular protrusion on the door leaf's edge. When the door is closed, the magnetic strip planes on the doorpost and the door leaf are parallel and attracted to each other. The sealing and soundproofing structure covers the top, left, and right sides of the door frame or door leaf. The aluminum honeycomb panel refers to a panel with two aluminum plates on each surface and a honeycomb-shaped filling core in the middle. This utility model of a magnetically sealed all-aluminum alloy door is made of aluminum alloy profiles and honeycomb aluminum panels, featuring lightweight durability, neat appearance, and sturdiness without deformation. The sealing and soundproofing structure installed between the doorposts / stops and the door panel edge banding uses magnetic strips for sealing and soundproofing. The magnetic strips have a large contact surface and automatically engage, providing excellent sound insulation.

[0024] As one of the preferred technical solutions, a bottom door retainer 2-5 is also provided at the bottom edge of the door leaf. The bottom door retainer has a mountain-shaped cross-section and is fastened to the outside of the lower door leaf post. Adding a bottom door retainer can enhance the aesthetics of the door leaf and at the same time improve the sealing and sound insulation effect of the door leaf.

[0025] As one of the preferred technical solutions, the door bottom stop strip is a combined structure, including an outer stop strip 2-5-1 and an inner stop strip 2-5-2; the outer stop strip is fastened to the outside of the lower door leaf post, and the inner stop strip is inserted into the bottom cavity of the outer stop strip. The combined structure of the door bottom stop strip allows for easy adjustment of the distance between the bottom surface of the door leaf and the ground to accommodate different carpet or doormat thicknesses, without requiring adjustments to the overall door leaf height due to variations in carpet or doormat thickness.

[0026] Obviously, the beneficial technical effect of this utility model of aluminum strip magnetic sealing all-aluminum alloy door is that it can effectively achieve sealing and sound insulation, and is not easy to deform or fall off, thus increasing the effectiveness, reliability and durability of door gap sound insulation and sealing.
