Description

Technical Field

[0001] This utility model relates to the field of home decoration, and in particular to an environmentally friendly surface-coated composite wood door. Background Technology

[0002] Composite wood doors are solid or near-solid doors made primarily of wood, plywood, and other composite materials, with a surface layer of wood veneer or other covering materials. In solid wood composite doors, finger-jointed ordinary wood is often used as the base material, serving as structural connections and a frame to improve resistance to deformation. The engineered wood used is mainly medium-density fiberboard (MDF), which has uniform material properties, good milling performance, and can be used as decorative components.

[0003] For example, patent number 202123224846.8 discloses an impact-resistant and environmentally friendly wooden door, including a wooden door structure. The wooden door structure includes a polyurethane foam board, which is disposed inside the wooden door structure. Filling areas are provided on the left and right sides of the polyurethane foam board, and the filling areas are filled with a grid-like wooden door filler. A reinforcing keel is provided in the wooden door filler near the end of the filling area of ​​the polyurethane foam board. Decorative panels are provided on the front and back sides of the polyurethane foam board and the filling areas. The decorative panels include a waterproof board and a wood veneer. The inner side of the waterproof board is tightly attached to the polyurethane foam board and the filling area, and the wood veneer is tightly attached to the outer side of the waterproof board.

[0004] The above technical solution uses polyurethane foam board as the core board to improve the impact absorption capacity of the wooden door. At the same time, the filling area with embedded reinforcing keel is set on both sides of the polyurethane foam board to improve the overall strength of the wooden door.

[0005] However, the wooden door structure of the above-mentioned technical solution contains polyurethane foam board, wooden door filler, reinforcing keel and decorative panel, all of which contain certain non-environmentally friendly materials.

[0006] Therefore, it is necessary to improve such a structure to overcome the above-mentioned defects. Utility Model Content

[0007] The purpose of this invention is to provide an environmentally friendly surface-coated composite wood door to solve the problems existing in the prior art.

[0008] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0009] An environmentally friendly surface-coated composite wooden door includes laminated veneer lumber for the core layer, which is also used as the frame material. A filler is provided on the end face of the laminated veneer lumber. A medium-density fiberboard (MDF) is provided on the front and rear sides of the laminated veneer lumber and the filler. The MDF, through a composite process, forms the wooden door with the laminated veneer lumber and the filler. A PVC film is applied to the outer surfaces of the laminated veneer lumber, the filler, and the MDF. A glass decorative panel is provided inside the wooden door, and the glass decorative panel is connected and fixed to the wooden door via a door fitting.

[0010] Furthermore, the door kit includes a first door frame and a second door frame, which are disposed opposite to each other on the wooden door. A guide block is provided on the inner end of the first door frame, and a guide groove is provided on the inner end of the second door frame. The first door frame extends into the guide groove through the guide block and is connected to the second door frame.

[0011] Furthermore, the end of the glass decorative panel is positioned between the first door frame and the second door frame. The door frame limits the glass decorative panel by adjusting the position of the guide block and the guide groove. A dot glue groove is also provided on the first door frame and the second door frame. After the glass decorative panel is limited and installed, it is fixed by injecting glass glue into the dot glue groove.

[0012] Furthermore, the first door frame and the second door frame include an inner wood-plastic composite substrate and a PVC film covering the outer surface of the wood-plastic composite substrate.

[0013] In summary, this utility model has the following beneficial effects:

[0014] By embedding environmentally friendly glass decorative panels inside the wooden door structure and setting up a first door frame and a second door frame, the fixed position of the glass decorative panels can be easily installed and adjusted. Attached Figure Description
