A locking technology can be widely used in the hardwood and laminate floor installation process. After being spliced, the two-locking structure has bearing capacity similar to that of a whole single material. The technology can be reversely disassembled, and both sides of the locking device are tightly sealed. The glue-free structure has multiple applications, including use in laminated boards, composite floorboards, furniture, and a new separable spliced process, other than welding, for metal boards with thickness over 5 mm.
The floorboard splicing effect enables a whole structural force. Because both sides can be tightly sealed, a moistureproof effect is also achieved. The A/A splicing principle and matching structure provide an improved utilization rate.
