Background technique [0002] With the gradual improvement of living standards, people's living and office environment and decoration taste are also constantly improving, so wooden flooring is more and more popular among people. At present, the tongue-and-groove design of the wooden floor generally adopts the flat buckle structure. The firmness of the wooden floor with the flat buckle structure is not satisfactory, and because there is no gap between the floors, it is easy to cause the floor to warp due to wet expansion and shrinkage. At the same time, the existing flat buckle structure is prone to generate noise, which affects the user's quality of use. How to produce a wood floor that can solve the above problems has become a difficult problem to be solved urgently in the wood floor industry. Contents of the invention [0003] The techn...
