The chicken beak hinge is installed in the grooves, and grooves are also arranged at the corresponding positions of the door frame. The groove depths of the door panel main body and the door frame are equal to the thickness of the chicken beak hinge.

[0008] Further, a white fluorocarbon spray coating is arranged on the inner surface of the door panel main body.

[0009] Further, a sandblasted rough surface is arranged on the outer surface of the door panel main body, and an interface agent is applied and wallpaper is pasted on the sandblasted rough surface.

[0010] Further, a push-pull handle and a hidden mechanical lock are also arranged on the outer side of the door panel main body.

[0011] Further, stainless steel edging strips are arranged at the edges of the door panel main body and the door frame.

[0012] The beneficial effects of the prefabricated lightweight decorative concealed door described in the present utility model include: the door leaf and door frame are integrally formed with honeycomb panels, which can avoid the deformation of the concealed door in the later stage, and have reasonable design, simple structure, simple production process and low cost; the back is treated with powder spraying, and no further treatment is required after installation; the chicken beak hinges are pre-assembled and reinforced, with unified standards, reducing the errors caused by on-site assembly; the whole is a honeycomb panel, which is light in weight, has low requirements for the specifications of hardware, and can avoid problems such as the door dropping corners and abnormal noises caused by sagging during the later use process, saving maintenance costs, and can adapt to the humid environment of pipe wells by using aluminum honeycomb to prevent moisture and water, improving durability. The concealed door lock uses a spring-loaded handle, and the door lock uses a hidden mechanical lock, which can better enhance the decoration and concealment of the concealed door.
