Description

Technical Field

[0001] The present invention relates to the technical field of floors, and in particular to a floor comprising coupling components. Background Art

[0002] As a covering material for the interior and exterior of a building, flooring has important functional and aesthetic value. Among them, spliced ​​flooring is a type of flooring that combines multiple floorboards together through a specific connection method, usually using a lock or mortise and tenon structure.
