Description
Technical Field
[0001] The utility model belongs to the technical field of wooden doors and relates to a wooden door containing a door core board. Background Art
[0002] The wooden door containing a door core board is a common type of door in the market. As the internal filling material of the door, the door core board has an important impact on the overall performance of the door. When the wooden door cannot effectively prevent the door body from swelling due to long-term indoor humidity during use in a humid environment for a long time, a series of serious problems may occur. These problems not only affect the normal use of the wooden door but also may cause many inconveniences to the home environment and the daily life of the occupants.
[0003] The swollen door body will get stuck in the door frame, making it difficult to open and close the door. Even forced pushing and pulling are required to barely open or close it. This not only increases the inconvenience of use but also may cause additional damage to the door body and the door frame. The wooden door that has been soaked in moisture for a long time is prone to losing its original shape, becoming distorted or uneven, seriously affecting its aesthetics. Due to the change of moisture inside the wood, cracks may also appear on the surface of the door body, further reducing its service life. Therefore, there is an urgent need for a wooden door containing a door core board to solve the above problems. Summary of the Utility Model
