Description

Technical Field

[0001] This utility model relates to the field of home decoration, and in particular to a flat cabinet door with an internal frame structure. Background Technology

[0002] Existing cabinet door panels include plywood, blockboard, and wood-based eco-board doors. Plywood is an odd-numbered multi-layer rotary-cut veneer composite with longitudinal and transverse symmetrical bonding. Blockboard uses core board as the base board, with a transverse veneer and a longitudinal veneer on the surface layer symmetrically bonded on both sides. Wood-based eco-board replaces core board with oriented strand board. The common point of their production process is that the veneer is glued and hot-pressed.

[0003] For example, patent number 201920323538.4 discloses a multifunctional convex and concave cabinet door structure, including two parallel side strips, a crossbar located between the two side strips, and a cabinet door core panel set in the middle frame formed by the side strips and the crossbar. Adjacent side strips and crossbars are spliced ​​with 45-degree angle tenon joints, and the two side strips are also connected by at least one metal reinforcement. The metal reinforcement includes a strip plate, and the two sides of the strip plate are symmetrically provided with limiting plates. The strip plate is connected to the side strips, and the limiting plates are in contact with the cabinet door core panel.

[0004] The above technical solution, by using metal reinforcement, prevents cabinet doors from bulging and ensures the finished product is handled securely. The modular and functional design of the metal reinforcement components expands the practical functions for users, enhancing both customer experience and business efficiency.

[0005] However, due to the significant difference in expansion properties between metal parts and wood materials, both will experience varying degrees of bending, warping, and twisting under the same humidity conditions, leading to the loosening of the connection structure. This phenomenon becomes more severe as the cabinet door size increases, which determines that it cannot be used for large cabinet doors, especially tall cabinet doors.

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

[0007] The purpose of this utility model is to provide a flat cabinet door with an internal frame structure 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] A flat cabinet door with an internal frame structure includes an integrated material used as a core board, the integrated material including square tubes and filler, a plurality of square tubes being evenly distributed inside the integrated material, and filler being provided between the square tubes;

[0010] Multi-layer boards are provided on the front and rear sides of the engineered wood, the multi-layer boards including solid wood boards and high-density fiberboard, the solid wood boards are arranged on the inner side of the multi-layer boards and fixedly connected to the engineered wood, and the high-density fiberboard is arranged on the outer side of the multi-layer boards.

[0011] A decorative material layer is applied to the outer surface of the engineered wood and multilayer board. The decorative material layer includes a wood veneer layer and a PVC layer. The wood veneer layer is disposed on the outer surface of the high-density fiberboard, and the PVC layer is disposed on the left and right sides of the filler, solid wood board and high-density fiberboard.

[0012] Furthermore, the top and bottom surfaces of the square tube and the filler are flush and connected by a composite process to form an engineered wood.

[0013] Furthermore, the solid wood board and high-density fiberboard are connected as one unit through a composite process. The solid wood board on the inner side is connected to the engineered wood through a composite process, and the high-density fiberboard on the outer side is connected to the decorative material layer through a composite process.

[0014] In summary, this utility model has the following beneficial effects:

[0015] The engineered wood and plywood included are made of wood or are composite structures made of various wood materials. Their expansion properties are similar, so there will be no loosening of the connection due to differences in expansion properties. In addition, since wood is a soft material and has small gaps inside, it can also play a role in resisting deformation. Attached Figure Description
