Description

Technical Field

[0001] The utility model relates to the technical field of furniture production, and particularly relates to a deformation-proof framed door. Background Art

[0002] Please refer to Figure 10 , there is a seamless framed door on the market today. It is formed by splicing a frame strip covered with a decorative material such as CPL or melamine impregnated film paper with a door panel. Through visual inspection, no gap can be seen at the splicing place of the frame strip and the door panel, achieving the "seamless" effect and greatly improving the aesthetics of furniture made of decorative materials.

[0003] For the frame strip and the door panel covered with decorative materials, their core layers usually adopt wooden materials such as density board, particle board, and OSB board. These wooden core materials will all have a certain problem of absorbing moisture and swelling during use, especially in the humid and rainy seasons in the south, where the absorption of moisture and swelling is more obvious.

[0004] Since the outer side wall of the seamless framed door is close to the wall during use and lacks the covering of decorative materials such as CPL or melamine impregnated film paper, only an edge banding is used for covering. Therefore, when moisture absorption and swelling occur, it mainly occurs on the outer side edges of the frame strip and the door panel (i.e., the side covered by the edge banding) and gradually penetrates inward. Since the existing seamless framed door frame strip and door panel are both multi-sided sealed and covered structures, the moisture absorption of the outer side edge of either of them will not affect the other, resulting in inconsistent degrees of moisture absorption and swelling of the two, thus causing the problem of moisture-induced deformation. In addition, when different materials are used for the frame strip and the door panel, due to the inconsistent coefficient of thermal expansion of different materials, deformation will also occur when heated.

[0005] It can be seen that the existing technology still needs to be improved. Content of the Utility Model

[0006] In view of the above deficiencies of the existing technology, the purpose of the present utility model is to provide a deformation-proof framed door, aiming to solve the technical problem that the overall structure of the framed door in the existing technology is deformed due to inconsistent degrees of moisture absorption and swelling of different structures.

[0007] In order to achieve the above purpose, the present utility model adopts the following technical solutions:

[0021] Beneficial effects: The present utility model provides an anti-deformation assembled frame door. By providing a telescopic deformation joint between the outer side of the bottom surface of the border strip and the top surface of the door panel, a certain expansion and contraction space is reserved to avoid the overall structure deformation of the assembled frame door caused by mutual extrusion after expansion.

The first core material 11 and the second core material 211 can also be made of the same or different materials. Usually, the first core material 11 and the second core material 211 are made of wood materials. During use, since moisture (humidity) usually gradually penetrates inward from the outer side of the framed door, the moisture absorption and expansion occur more significantly on the outer side of the bottom surface of the border strip 21 and the outer side of the top surface of the door panel 1. The setting of the telescopic deformation joint 4 avoids the close connection between the outer side of the bottom surface of the border strip 21 and the outer side of the top surface of the door panel 1, leaving an expansion and contraction space for the two structures, thus avoiding the problem of deformation of the framed door caused by moisture absorption and expansion.

[0040] Specifically, the telescopic deformation joint 4 is covered by the edge sealing strip 3 and hidden inside the framed door.

[0044] In the above two embodiments, the expansion and contraction deformation joint 4 is continuous and extends along the length direction of the border strip 21.

[0045] Please refer to Figure 8 , in another embodiment, the expansion and contraction deformation joint 4 includes a plurality of groove bodies 8 arranged at intervals; the plurality of groove bodies 8 are arranged in sequence along the length direction of the border strip 21.

[0046] Please refer to Figure 9 , in one embodiment, the first decorative layer 12 is provided at the connection between the door panel 1 and the border strip 21. The first decorative layer 12 can improve the moisture-proof performance at the connection between the door panel 1 and the border strip 21.

[0047] Please refer to Figure 9 , in one embodiment, the second decorative layer 212 is provided at the connection between the border strip 21 and the door panel 1. The second decorative layer 212 can improve the moisture-proof performance of the inner side of the bottom of the border strip 21.
