Description

Technical Field

[0001] The utility model relates to the technical field of interior door production, in particular to an anti-deformation interior door structure. Background Art

[0002] Interior doors differ from security doors in that they offer less protection but serve a decorative purpose. Most interior doors are made of wood, but due to the decline of forest resources, tree resources are becoming increasingly scarce, and their cost is also higher. Existing interior doors are mostly made of environmentally friendly materials, with eco-friendly panels being the most commonly used, offering excellent dimensional stability, high strength, environmental friendliness, flame retardancy, and weather resistance. During use, eco-friendly panels can easily deform due to the opening and closing of interior doors and the effects of internal stress. This deformation can cause the door to not close securely or even crack. The frame is the primary location for deformation during use, so improving the frame's stability can extend the interior door's lifespan and effectively prevent deformation.

[0003] Patent document CN217841384U discloses an environmentally friendly interior door with an anti-deformation function. The door comprises a middle frame, wherein an environmentally friendly panel is embedded and fixedly connected to the middle frame. The environmentally friendly panel comprises a composite panel, wherein the composite panel has stress-bearing areas at the four corners, the center of the composite panel being the central area, and an insertion opening for the middle frame to be inserted at the junction of the central area and the stress-bearing area. The top and bottom of the composite panel are embedded with vertically placed anti-bending columns at the stress-bearing areas, and the front and back of the middle frame are fixedly connected to decorative panels. This environmentally friendly interior door with an anti-deformation function reinforces the environmentally friendly panel by embedding the environmentally friendly panel within the middle frame and providing an insertion opening in the middle area of ​​the environmentally friendly panel for the insertion frame on the middle frame to pass through. The anti-bending columns are inserted in the stress-bearing areas of the composite panel where stress is greater, thereby further preventing deformation of the door, which may cause the door to close loosely or even crack. At the same time, to reduce the impact force generated when opening and closing the door, L-shaped cushioning stickers are installed on the corners of the decorative panel. The cushioning effect of the cushioning stickers can reduce the impact force on the door, thereby further reducing the probability of door deformation. The installation of anti-bending columns in this interior door is more difficult, and the anti-deformation ability of the frame is not strong.

[0004] Patent document CN209523639U discloses an environmentally friendly interior door that is resistant to deformation and cracking. The door panel has a solid wood core panel installed inside, and an anti-deformation steel profile is installed below the solid wood core panel. The outer surface of the anti-deformation steel profile is filled and wrapped with environmentally friendly sound insulation material. The lower end of the anti-deformation steel profile is provided with a steel component, and the edges of the door panel are provided with PVC edge banding. Installing the anti-deformation steel profile below the solid wood core panel increases the weight of the door panel and increases production costs. The anti-deformation ability of the frame is not strong. Utility Model Content
